[0002] Car keys are tools for unlocking and starting the car. Traditional car keys require inserting the physical key into the keyhole to unlock the car door, which is relatively cumbersome. To address this issue, major automakers and parts suppliers have introduced in-car smart keys to replace traditional physical keys for controlling car unlocking and locking. Simply pressing a button on the in-car smart key unlocks and locks the vehicle, and the in-car smart key also allows keyless starting. However, the control mounting plate of existing in-car keys is screwed onto the key housing. The control mounting plate integrates control circuit components and chips, making it difficult to disassemble for maintenance. Utility Model Content

DETAILED DESCRIPTION

[0021] like Figures 1 to 5 As shown, a vehicle key mounting plate includes a front key shell 1, a rear key shell 2 and a control mounting plate 3. A mounting frame 4 is fixed on the rear key shell 2. The inner wall shape of the mounting frame 4 matches the outer wall shape of the control mounting plate 3. The control mounting plate 3 is adapted to the mounting frame 4. The inner wall of the mounting frame 4 is provided with a plurality of limiting notches 5. The plurality of limiting notches 5 are arranged at intervals around the mounting frame 4. The side walls of the control mounting plate 3 are fixed with limiting blocks 6 corresponding to the positions of the limiting notches 5. The limiting blocks 6 are adapted to the limiting notches 5. An elastic protrusion 7 is provided at the front and rear of the front key shell 1. The elastic protrusion 7 is in a compressed state and contacts the control mounting plate 3 for fixing the control mounting plate 3 is restricted within the mounting frame 4. The control mounting plate 3 is installed within the mounting frame 4. The control mounting plate 3 is limited and positioned by the cooperation of the limiting block 6 and the limiting notch 5 to limit the freedom of horizontal movement of the control mounting plate 3. After the rear key shell 2 and the front key shell 1 are connected together, the elastic protrusion 7 presses on the control mounting plate 3, thereby further limiting the control mounting plate 3, which is used to limit the freedom of vertical movement of the control mounting plate 3. This achieves horizontal and vertical positioning of the control mounting plate 3, ensuring stable installation of the control mounting plate 3 without the use of screws, and facilitating later disassembly of the control mounting plate 3 for maintenance. In specific implementations, the control mounting plate 3 is a PCB board for integrated circuits and electronic components.

[0022] Furthermore, if Figures 1 to 3As shown, the front key shell 1 is fixed with an annular shell 8 at the position where the elastic protrusion 7 is set. The elastic protrusion 7 is interference fit in the annular shell 8. The height of the elastic protrusion 7 is greater than the height of the annular shell 8. The elastic protrusion 7 includes a conical section 9 and a cylindrical section 10. The large diameter end of the conical section 9 is connected to the cylindrical section 10. The diameter of the cylindrical section 10 is greater than the inner diameter of the annular shell 8. The minimum diameter of the conical section 9 is smaller than the inner diameter of the annular shell 8. The conical section 9 of the elastic protrusion 7 is inserted into the annular shell 8. Since the minimum diameter of the conical section 9 is smaller than the inner diameter of the annular shell 8 , so that the elastic protrusion 7 can be easily inserted into the annular shell 8. Through the guidance of the tapered section 9, the elastic protrusion 7 is squeezed and deformed to fit into the annular shell 8, so that the elastic protrusion 7 is stably installed in the annular shell 8. When the front key shell 1 and the rear key shell 2 are connected, the elastic protrusion 7 will not fall off. Because the height of the elastic protrusion 7 is greater than the height of the annular shell 8, the elastic protrusion 7 protrudes from the annular shell 8, so that the elastic protrusion 7 contacts the control mounting plate 3 to limit the position, thereby preventing the annular shell 8 from contacting the control mounting plate 3 and causing scratches or crushing. Preferably, the elastic protrusion 7 is made of insulating rubber material so as not to affect the circuit transmission on the control mounting plate 3.

[0023] Furthermore, if Figure 1 、 Figure 4 and Figure 5 As shown, it also includes a mechanical key 12. A keyhole 11 is provided at one end of the rear key shell 2. The mechanical key 12 is adapted in the keyhole 11. The lock teeth of the mechanical key 12 face the mounting frame 4. A lock cavity 13 is provided in the rear key shell 2. The lock cavity 13 faces one of the lock teeth of the mechanical key 12, and the lock cavity 13 is communicated with the keyhole 11. A lock body 14 is slidably adapted in the lock cavity 13. Under normal circumstances, the lock body 14 is adapted in the lock teeth corresponding to the mechanical key 12. When the vehicle key is out of power, the vehicle door is opened by the mechanical key 12. The mechanical key 12 includes a key handle and a key body. The key body is inserted into the keyhole 11, and the key handle contacts the front key shell 1 and the rear key shell 2. Under normal circumstances, the lock body 14 is inserted into one of the lock teeth of the mechanical key 12 to confine the mechanical key 12 in the rear key shell 2 to prevent it from falling.

[0024] Furthermore, if Figure 5As shown, a spring 15 is disposed within the lock cavity 13. The two ends of the spring 15 connect the lock body 14 and the rear key shell 2, respectively. An unlocking slot 16 is provided on the back of the rear key shell 2, which communicates with the lock cavity 13. A drive block 17 is fixed to the lock body 14, extending into the unlocking slot 16. A plurality of tooth grooves 18 are densely formed on the end of the drive block 17 away from the lock body 14. By detent action on the tooth grooves 18, the drive block 17 is driven to move within the unlocking slot 16, thereby driving the lock body 14 to move within the lock cavity 13, causing the lock body 14 to be inserted into or disengaged from the lock teeth of the mechanical key 12. When the lock body 14 is disengaged from the lock teeth, the mechanical key 12 can be removed and used. In specific implementation, the front key shell 1 and the rear key shell 2 are connected using existing technology, i.e., screws or snaps. A snap connection is preferably used for easy disassembly.

[0025] Furthermore, if Figure 1 As shown, a disassembly space is formed between the control mounting plate 3 and the inner bottom wall of the rear key shell 2, and a disassembly notch 19 is opened at one end of the mounting frame 4. The disassembly notch 19 passes through the top of the mounting frame 4, and the disassembly notch 19 is communicated with the disassembly space. After disassembling the front key shell 1 and the rear key shell 2, the mechanical key 12 is taken out, and the mechanical key 12 is inserted into the disassembly space through the disassembly notch 19. The control mounting plate 3 is taken out of the mounting frame 4 by using the mechanical key 12, which makes the removal of the control mounting plate 3 simpler and faster, and will not cause damage to the control mounting plate 3.
