[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0027] A cantilever key structure provided in the utility model, referring to Figure 1-3 , including a button 1 and a cantilever 2 connected to the button 1, the button 1 is arranged in a circular shape, the cantilever 2 is arranged in a concave arc shape, and the thickness of the cantilever 2 close to the button 1 is greater than the thickness of the cantilever 2 away from the button 1.

[0028] First, from the perspective of ergonomics, the cantilever key structure with a concave arc shape is more in line with the shape of human fingers. Fingers vary in shape, but most people's fingers have a natural curvature. The concave arc shape can better fit the user's fingers and improve the comfort of operation. Secondly, because the contact area between the keys and fingers of this design is large, the pressure on the keys by the user during operation is relatively uniform, which can reduce the wear of the keys and extend the service life of the equipment. The cantilever key structure with an arc and groove shape helps to improve the durability of the equipment. In addition, the cantilever key structure with an arc and groove shape helps to improve the accuracy of the operation. During the operation, the fingers can be better positioned on the keys, reducing the possibility of misoperation. For the keys with grooves, when the fingers touch the keys, the position of the grooves can be immediately sensed, thereby accurately operating.

[0029] Among them, in order to adapt to different stress conditions and ensure the stability of the structure, the thickness of the end arm of the cantilever 2 close to the button 1 is larger. This is because the force borne by this part of the cantilever 2 is larger, and it needs to have sufficient thickness to ensure its stability. If the thickness is insufficient, it may cause the cantilever 2 to bend or break, thereby affecting the stability of the entire structure; while the thickness of the end arm of the cantilever 2 away from the button 1 is smaller, because the force borne by this part of the cantilever 2 is relatively small, and the thickness requirement is lower. Under the premise of meeting the overall structural stability of the cantilever 2, the thickness of the cantilever 2 can be appropriately reduced to reduce costs and reduce structural weight, so that the cantilever 2 can perform well in various application scenarios.

[0030] Reference Figure 3 The upper end face angle of the cantilever 2 near the end arm of the button 1 is in the range of 4 to 8 degrees, and the lower end face angle is in the range of 6 to 15 degrees, which can effectively ensure the strength and rigidity of the cantilever 2 near the end arm of the button 1. In the cantilever 2 structure, the part near the end arm of the button 1 is subjected to a large torque. If the strength and rigidity of this part are insufficient, the cantilever 2 may be deformed or damaged during use. When the button is pressed, the cantilever 2 will be affected by the force. If the angle of the cantilever 2 is designed to be too large, the cantilever 2 may not be able to deform normally, thereby affecting the service life and performance of the button.

[0031] Reference Figure 4 The diameter of button 1 ranges from 5 to 10 mm. From an ergonomic point of view, a button 1 diameter of 5 to 10 mm is in line with the habits of most people. Within this range, users can easily place their fingers on button 1 and press it. Compared with buttons 1 with diameters that are too large or too small, a diameter in this range can make users more comfortable during operation.

[0032] The utility model provides a car remote control key, referring to Figure 5-7, including an inner cover 3, the inner cover 3 is provided with an air avoidance groove 4, the button 1 is arranged in the air avoidance groove 4, and the air avoidance groove 4 is arranged in a circular shape with a diameter range of 12 to 16 mm. The circular design of the air avoidance groove 4 enables the force to be evenly distributed around the groove when the button 1 is pressed, thereby avoiding the force from being concentrated on a certain point and reducing the risk of damage to the inner cover 3; the circular air avoidance groove 4 can better disperse the force when subjected to pressure, so that the inner cover 3 is not easy to deform, which greatly improves the service life of the remote control key and enables it to maintain good performance during long-term use.

[0033] Reference Figure 6 The car remote control key also includes a cover 5, a waterproof rubber pad 6, a circuit board 7, a battery 9 shell 8, a battery 9 and a back cover 10. The cover 5 is connected to the inner cover 3 by a buckle. The inner cover 3 integrates the button 1 through a cantilever key structure. The waterproof rubber pad 6 is assembled between the inner cover 3 and the circuit board 7. The circuit board 7 is triggered by pressing the cover 5. Among them, the cover 5 is the outer protective layer of the car remote control key, which plays a role in preventing the wear and damage of the key surface. The cover 5 is connected to the inner cover 3 by a buckle. This design makes the structure between the cover 5 and the inner cover 3 more compact, which is conducive to preventing dust and moisture from invading the inside of the key; the inner cover 3 is the core part of the remote control key, which integrates various buttons 1 together through a cantilever key structure, so that the user can easily operate the remote control key to realize functions such as unlocking the car door and starting the engine; the waterproof rubber pad 6 between the inner cover 3 and the circuit board 7 plays a sealing role to prevent moisture and dust from damaging the circuit board 7, thereby ensuring the stable performance of the remote control key; the circuit board 7 is the control center of the car remote control key, which is responsible for receiving and processing the signal sent by the user operating the button 1, thereby realizing various functions of the remote control key. In order to ensure the normal operation of the circuit board 7, the battery 9 shell 8 and the battery 9 provide a stable power supply; the battery 9 shell 8 is a protective shell for the battery 9, which can prevent the battery 9 from accidental damage and extend the service life of the battery 9. The back cover 10 is located at the bottom and is also connected to the inner cover 3 by a snap to achieve the integrity of the overall structure.

[0034] The orthographic projection of the button 1 on the circuit board 7 covers the orthographic projection of the micro switch 11 on the circuit board 7, wherein the micro switch 11 is a switch with a relatively small volume, which can realize the on and off of the circuit when subjected to external force. The orthographic projection of the button 1 on the circuit board 7 covers the orthographic projection of the micro switch 11 on the circuit board 7, so that the button 1 can realize the on and off of the circuit by pressing or releasing it.

[0035] Specifically, the inner cover 3 includes at least two cantilever button structures. In the present embodiment, three cantilever button structures are provided. Among them, the micro switches 11 on the circuit board 7 correspond one-to-one to the cantilever button structures. The button 1 in the cantilever button structure is located directly above the micro switch 11. When the user presses the button 1, the cantilever button structure transmits the force of the button 1 to the micro switch 11. After receiving the force, the micro switch 11 will generate corresponding mechanical movement, thereby triggering the circuit board 7 for signal processing. This design makes the cantilever button structure have higher sensitivity and accuracy, which greatly improves the operation convenience of the electronic device.

[0036] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
