[0024] The specific implementation of the utility model is further described in detail below through the description of embodiments in conjunction with the accompanying drawings.

[0025] A remote control key, such as the one Figure 1 ,2 As shown, a remote control switch 20 is provided on the key housing 10. In this embodiment, the remote control switch is a button type, including a lock button 21 for closing the door lock, and also includes a switch button for controlling the opening of the door lock and the opening of the trunk. In other embodiments, the remote control switch 20 can also be in other forms such as a knob, a touch screen, etc.

[0026] The key housing 10 is also rotatably connected to a cover plate 30, and the cover plate 30 avoids the locking button 21, so that the locking button 21 is always in an exposed state. The cover plate 30 rotates around its rotation axis and moves between the position of shielding the remote control switch and the position of revealing the remote control switch. The rotation axis of the cover plate 30 is arranged along the thickness direction of the key housing 10, so that the cover plate 30 moves horizontally along the upper surface of the remote control switch 20 as a whole, as shown in the attached figure. Figure 1 As shown, when the cover plate 30 is in the closed state, all remote control switches 20 except the vehicle lock button 21 are blocked, and the cover plate 30 is rotated to the adjacent Figure 2 In the unfolded state shown, all remote control switches 20 are exposed. The lock button 21 for closing the door lock is exposed, so that the user can conveniently lock the vehicle without opening the cover 30, thereby ensuring the convenience of the lock operation. Even if the lock button 21 is accidentally touched during use, it only issues a lock command and will not accidentally unlock the vehicle, thereby ensuring convenient vehicle lock control while avoiding vehicle damage or user property loss.

[0027] Details are as attached Figure 2 As shown, in this embodiment, the remote control switches 20 are arranged in a row in the length direction of the key housing 10 to form a remote control switch row 20a, and the hinged connection position between the cover plate 30 and the key housing 10 is set at one end of the remote control switch row 20a, and the long edge of the cover plate 30 away from the hinged connection position is consistent with the outer contour of the key housing 10. Fig.17 , 18 As shown in FIG. 1 , a cover plate 30 can be used to cover the hinged connection position between the key housing 10 and the remote control switch array 20a. Figure 1 , 2 In the embodiment shown, two cover plates 30 are hingedly connected to the key housing 10, and the plates of the two cover plates 30 are symmetrically arranged with the axis in the length direction of the key housing 10 as the center, so that each cover plate 30 can be rotated at a small angle to expose all the remote control switches 20. The user can hold the remote control key with the cover plate 30 unfolded in one hand, and then naturally close the cover plate 30 by naturally closing the fingers to hold the remote control key, which is easy to operate. In addition, this also makes the plate area of ​​the cover plate 30 on the side of the key housing 10 in the unfolded state smaller, which can prevent the cover plate 30 in the unfolded state from being damaged by external force folding or twisting. For details, see the attached Figure 1 , 2As shown in FIGS. 7 and 8, the lock button 21 is located in the middle of the remote switch array 20a, and the adjacent edges of the two cover plates 30 are arranged along the length direction of the key housing 20.
