Integrated structure of power source of power winch and electric control box

Abstract

In an integrated structure of a power source of a power winch and an electric control box, the electric control box of the power winch is integrally combined with the top of the power source by a support frame, and an outer cover is provided for axially covering the electric control box and the power source and locked and connected to a front shell wall, so that the electric control box and the power source are completely hidden in the outer cover without any exposure. In other words, the electric control box is combined with the power source by a hidden assembly mode, so that the electric control box can be securely assembled without any risk of being shaken or falling off. In the meantime, the electric control box is hidden in the outer cover, and thus it will not be affected by weather at all.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) The objectives, technical measures and effects of the present invention will become clearer in light of the following detailed description of an illustrative embodiment of this invention described in connection with the drawings.

(8) With reference to FIGS. 1 and 2 for a power winch 1 in accordance with an embodiment of the present invention, the power winch 1 includes a power source 11 (such as a power motor, an electric DC motor, etc.), and after the power outputted by the power source 11 is transmitted to an deceleration device 12 to drive a rope wheel 13 to perform a forward rotation or a reverse rotation in order to release or retract a rope, when needed. For simplicity, the rope is not shown in the figures, the rope wheel 13 is disposed transversally at the central position of a support frame 14, the power source 11 is mounted on a side of the support frame 14, the deceleration device 12 is mounted on the other opposite side of the support frame 14, the power transmission between the power source 11 and the deceleration device 12 is passed without touching through the interior of the cylinder shaft of the rope wheel 13, and then the deceleration device 12 substantially drives the whole rope wheel 13 to rotate, and the rope wheel 13 and the support frame 14 are connected with each other by a bearing to achieve the effect of maintaining the support frame 14 stably unmoved during the rotation of the rope wheel 13, and the power source 11, the deceleration device 12, the rope wheel 13, the rope and the support frame 14 form a “winch host”.

(9) In FIGS. 3 and 4, the front end of the power source 11 is fixedly connected to a sidewall of the support frame 14 by a front shell wall 51, and the power source 11 is locked onto the front shell wall 51, so as to define a relationship status that the front shell wall 51 supports the power source 11, and then the top of power source 11 is connected to an electric control box 15, as shown in FIGS. 5 and 6, and the bottom of the electric control box 15 is locked and connected to a support frame 151, and the support frame is also locked and connected to the top of the power source 11, so that the electric control box 15 is directly locked with the top of the power source 11 and integrated with the power source 11 as a whole. In FIG. 5, the electric control box 15 and the power source 11 are connected with each other by a plurality of electrical connectors 152, so that the electric control box 15 and the power source 11 are electrically connected. After the electric control box 15 and the power source 11 are combined, the external periphery axially cover the electric control box 15 and the power source 11 by an outer cover 50, and the outer cover 50 is locked and connected with the front shell wall 51 to define the status that the outer cover 50 and the front shell wall 51 simultaneously cover the electric control box 15 and the power source 11 therein. A plug-in hole 52 is reserved at the top of the outer cover 50, and a plug-in rod is disposed in the plug-in hole 52 and electrically connected with the electric control box 15, and the plug-in hole 52 is provided for plugging a plug of a wired remote controller (not shown in the figure), so that the wired remote controller and the electric control box 15 can be electrically connected. When the plug-in hole 52 is not in use, the slot of the plug-in hole can be covered by a cover 53. Before use, it is necessary to open the cover 53 to expose the slot of the plug-in hole 52.

(10) The major improvement of the present invention resides on that the electric control box 15 is locked to the top of the power source 11 by the support frame 151 and integrated with the power source 11 as a whole, and an outer cover 50 is provided to axially cover the electric control box 15 and the power source 11, and the outer cover is locked and connected to a front shell wall, so that the electric control box 15 is completely hidden in the outer cover 50 without any exposure. In other words, the electric control box 15 is combined with the power source 11 of the winch host in a hidden assembly mode, so that the electric control box 15 can be stably assembled without any risk of being shaken or falling off. Since the electric control box 15 is hidden in the outer cover 50, the electric control box 15 will not be affected by weather at all.

(11) In summation of the description above, the integrated structure of a power source of a power winch and an electric control box in accordance with the present invention is novel and can really achieve the expected creative purpose. Apparently, the invention complies with patent application requirements, and is thus duly filed for patent application.
