The present disclosure illustrates a fixing device including a fixing assembly, a first plate and a second plate. The fixing assembly includes a sleeve, a position-limiting device, an elastic element, and a fastener. A supporting surface of the second plate is slid along a guiding incline of a stop part of the fastener, so that a stop section and the stop part of the fastener can be respectively positioned in a first fastening recess and a second fastening recess of the second plate. Later, the user just needs to push the position-limiting device to separate the fixing assembly from the second plate. Therefore, effects of reliable positioning and easy detachment can be achieved.

A misting device has a form factor that allows the device to be handheld. The device includes a fluid tank that can be pressurized to force the contained fluid under pressure through a fluid delivery system. A hand-operated pump injects air into the fluid tank to pressurize the fluid tank. The pump includes a pump handle located at the bottom of the tank at one end of a rod, and a piston at the other end of the rod. A pressure-relieving air channel extends through the piston, the rod, and the pump handle to emit air out of the pump and into the environment when the fluid tank is at a maximum pressure. A pressure relief valve is disposed inside the piston to control the flow of air through the air channel. The pump handle locks against the tank using a twist-and-lock mechanism to remain secured in a retracted position.

A retention system for temporarily joining vehicle elements to one another includes a first vehicle element integral meshing surface and a second vehicle element integral cooperating meshing surface. The first vehicle element integral meshing surface and the second vehicle element integral cooperating meshing surface are adapted to engage one another to at least temporarily prevent separation of the first vehicle element from the second vehicle element. The integral meshing surface and integral cooperating meshing surface may each be defined by meshing tooth structures. The plurality of meshing tooth structures may be disposed in an aligned configuration. The system finds use in joining vehicle elements such as wrapped armrest trim pieces and armrests during vehicle assembly. Methods for temporarily joining vehicle elements using the described retention system are provided.

A joint assembly includes a structural body having a key which projects cantilevered from an abutment surface. The key includes a stem with a first stem portion having a reduced transverse encumbrance, and a second stem portion from which fins project and define locking surfaces. A seat body includes an abutment counter-surface facing the abutment surface. A seat is formed by opening from the abutment counter-surface, which delimits a key entry slot. A first seat portion proximate the entry slot allows insertion of the key if the fins are aligned with the entry slot. A second seat portion internal and opposite the entry slot widens to allow free rotation of the key. The seat body forms locking counter-surfaces having an inclined plane portion moving away from the entry slot so that key rotation brings the abutment surface in force-contact against the abutment counter-surface, creating a firm frictional fit.

An electric vehicle thermal management system and an electric vehicle using the thermal management system, wherein a passenger cabin is heated by the heat dissipated from a battery and/or a motor, and the battery and the electric motor are connected in different cooling paths. Heat is supplied to the passenger cabin by using the heat absorbed by cooling liquid from the battery and/or the motor, so that the electric power of the electric vehicle can be effectively utilized to increase the endurance mileage of the electric vehicle.

A method for the connection of a first component to a second component includes providing a first component which has a projection with an undercut, and providing a second component which has a cavity. The method also includes introducing a sealing and/or connecting material into the cavity of the second component, and joining the first component and the second component together to form a component arrangement. The projection of the first component projects, in the joined state, into the cavity of the second component.

A protective case for a handheld electronic device is provided. The protective case can include a removable mounting system comprised of an interlocking member and a plurality of mounting bases. The protective case may further include a non-slip member to prevent the device from slipping on a surface and a magnet for attaching the device to a magnetic surface.
