DETAILED DESCRIPTION OF EMBODIMENTS

[0029] In the disclosure, unless otherwise stated, the terms “first”, “second”, etc., used to describe various elements are not intended to limit the positional, temporal or importance relationship of these elements, but rather only to distinguish one component from the other. In some examples, the first element and the second element may refer to the same instance of the element, and in some cases, based on contextual descriptions, the first element and the second element may also refer to different instances.

[0030] The terms used in the description of the various examples in the disclosure are merely for the purpose of describing particular examples, and are not intended to be limiting. Unless the context clearly dictates otherwise, if the number of elements is not expressly limited, there may be one or more elements. In addition, as used in the disclosure, the term “and/or” encompasses any and all possible combinations of the listed items.

[0031] A schematic structural diagram of a concealed door handle according to an embodiment of the invention is shown in FIG. 1. As shown in FIG. 1, the concealed door handle 100 is composed of a handle body 110, a handle base 120, a deployment microswitch 130 and other components. The handle base 120 is fixed in a body of a vehicle. The handle body 110 is concealed in the handle base 120, and the handle body 110 is rotatably connected to the handle base 120. The deployment microswitch 130 is arranged on the handle base 120 and configured to detect a deployed position of the handle body 110 and to maintain communication with a vehicle control module. When the deployment microswitch 130 jumps from a triggered state into an untriggered state, the deployment microswitch 130 sends an input signal for unlocking an electronic lock to the vehicle control module. According to the concealed door handle of the invention, the state detection microswitch of the electric deployed position of the concealed door handle is also used as an signal input of the electronic lock for manually opening a door, and the two signals are advantageously obtained by the same mechanical structure, thereby simplifying the structure of the concealed door handle and reducing the number of parts.

[0032] In some embodiments of the invention, the concealed door handle further comprises a retraction microswitch (not shown) configured to detect a retracted position of the handle body 110 and to maintain communication with the vehicle control module. The retraction microswitch is arranged on the handle base 120.

[0033] In some embodiments of the invention, the handle body 110 has the retracted position A, the deployed position B and a release position C in sequence as the position of a rear end of the handle body changes from inside to outside.

[0034] When the handle body 110 is in the retracted position A, the deployment microswitch 130 is not triggered, and the retraction microswitch is triggered. In this case, the handle body 110 is located in the handle base 120.

[0035] When the handle body 110 is in the deployed position B, the deployment microswitch 130 is triggered, and the retraction microswitch is not triggered. In this case, an operator pulls the handle body 110 to unlock the vehicle door.

[0036] When the handle body 110 is in the release position C, neither the deployment microswitch 130 nor the retraction microswitch is triggered. In this case, the retraction microswitch remains untriggered, and the deployment microswitch 130 jumping from the triggered state to the untriggered state is used as an input signal for unlocking the electronic lock.

[0037] In some embodiments of the invention, the handle body 110 further comprises a fault state.

[0038] When the handle body 110 is in the fault state, the deployment microswitch 130 and the retraction microswitch are both triggered. In this case, since the deployment microswitch 130 and the retraction microswitch are both triggered, the handle body 110 cannot operate normally.

[0039] In some embodiments of the invention, the deployment microswitch comprises a microswitch trigger block 131 (see FIGS. 2 and 3), and the microswitch trigger block 131 has a distinct recess 132 configured for signal jump. As shown in FIG. 3, the micro switch trigger block 131 has a triggered region Y corresponding to the recess 132, and untriggered regions X.

[0040] In some embodiments of the invention, the handle body has a contact face 110, which forms a contactable connection with a side face (the triggered region Y) of the microswitch trigger block 131 that has the recess 132.

[0041] In some embodiments of the invention, the micro switch trigger block 131 is rotatable about a length direction of the handle base. As shown in FIG. 1, the microswitch trigger block 131 has a microswitch trigger block retracted position a, a microswitch trigger block deployed position b and a microswitch trigger block release position c in sequence as the position of the rear end of the handle body changes from inside to outside.

[0042] In some embodiments of the invention, when the deployment microswitch jumps from the triggered state into the untriggered state and sents the input signal for unlocking the electronic lock, the unlocking of an electronic door lock of the vehicle is commanded by the vehicle control module.

[0043] According to a further aspect of the invention, there is also provided a vehicle. The vehicle of the embodiment of the invention may comprise the concealed door handle described above. According to some embodiments, the concealed door handle described above may be mounted on a vehicle door of the vehicle. In the above, as a non-limited example, the vehicle is considered to be a type of motor vehicle, for example, refers to a car, a coach, a truck, or a commercial vehicle. However, the invention is not limited to this type of vehicle. In conclusion, the concealed door handle according to the invention has the advantages of simplified structure and low costs, and effectively solves the problem of arranging a signal source in a limited structural space.

[0044] Several specific embodiments are listed above to detail the concealed door handle and the vehicle of the invention, and these examples are only for explaining the principle of the invention and its embodiments, and not limiting the invention; and those of ordinary skill in the art can make various modifications and improvements without departing from the spirit and scope of the invention. As an example, the concealed door handle is a swing-out concealed door handle or a slide-out concealed door handle. Therefore, all equivalent technical solutions should fall within the scope of the invention and be defined by the claims of the invention.
