However, as the functions of modern new energy vehicles are gradually enriched, the functional controls that can be performed on the key end have also expanded from simple flashing lights and unlocking to high-level functions such as turning on the air conditioner and starting and closing the vehicle. When the key itself has many functions, it is limited by the relatively fixed size of the key, which may cause users to accidentally touch it, resulting in unnecessary trouble. Summary of the invention

[0003] The purpose of the present invention is to provide a car remote control key that prevents accidental touches, so as to solve the problem raised in the above background technology that as the functions of modern new energy vehicles are gradually enriched, the functional controls that can be performed on the key end have also expanded from simple flashing lights, unlocking, etc. to high-level functions such as turning on the air conditioner and starting and closing the vehicle. When the key itself has many functions, it is limited by the relative fixed size of the key, which may cause users to easily touch it by mistake, resulting in unnecessary troubles.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a car remote control key that prevents accidental touch, comprising a shell and a button arranged above the shell and for pressing. After the button moves, it contacts a trigger module installed on a circuit board in the shell and generates trigger information, and the information is processed by a micro-control module on the circuit board. The movement of the button includes movement in a non-vertical direction and movement in a vertical direction. After the non-vertical movement of the button is located above the trigger module, it moves in a vertical direction and contacts the trigger module.

[0005] Preferably, the button is installed in a cylinder, which moves in a vertically penetrating groove in the shell, and is guided by a guide mechanism arranged in the shell to drive the contact part in the button to move vertically by itself, wherein the contact part is slidably installed under the cylinder through a longitudinally distributed sliding rod.

[0006] Preferably, the guide mechanism comprises a guide rail with grooves therein and vertical spacing therebetween, the guide rail being divided into a horizontal section and an arc section connecting the upper and lower horizontal sections, wherein the trigger module is located below the lower horizontal section; Preferably, a roller is fitted in the groove in the guide rail, and the roller is connected to the contact portion via a rod, and the rod passes through the spacing gap between the upper and lower guide rails.

[0007] Preferably, the vertical projection point of the trigger module on the guide rail is located between the two ends of the low horizontal section of the guide rail.

[0008] Preferably, the surface of the cylinder is provided with an air hole, which is connected to the air supply mechanism and is located outside or inside the shell; Preferably, the air supply mechanism is used to generate airflow and blow it out from the air hole when the contact part is displaced.

[0009] Preferably, the air supply mechanism comprises a valve plate mounted on the top of the slide rod and vertically and sealingly slidably connected in the cylinder; Preferably, the space formed by the lower end surface of the valve plate and the bottom wall of the cylinder is communicated with the air hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the anti-accidental-touch automobile remote control key redesigns the button trigger logic, and achieves an effective anti-accidental-touch effect on the basis of ensuring convenient operation. At the same time, the hardware anti-accidental-touch solution design can greatly improve the overall use efficiency of the remote control key, as shown in the following content: 1. The use of the cylinder and the groove structure enables the button as a whole to slide horizontally in the key housing, and in this way avoids the finger from accidentally touching and triggering the wrong remote control information due to a simple pressing operation. The use of the guide rail and the roller can utilize the unique distribution form of the guide rail itself to make the button as a whole automatically adjust its vertical position at different horizontal positions when subjected to horizontal force, thereby achieving the effect of automatic pressing, thereby improving the efficiency of the use of the operation logic; Furthermore, the length design of the low-position horizontal section on the guide rail and the setting of the corresponding vertical position of the micro-hole module facilitate the user to achieve multiple pressing effects through a single operation, thereby enabling the effect of partially repeated pressing to trigger different functions to be achieved normally; Furthermore, the structural design of the slide bar and the valve plate enables the contact part to move vertically following the traction of the guide rail, which will drive the valve plate to move synchronously, thereby generating airflow or air pressure change effects, and generating different effects according to the different positions of the air holes, further improving the durability of the remote control key; 2. The structural design of the limiting plate and the circular plate can achieve the effect of physical prevention of accidental touches from another angle. It uses a simple lever principle to prevent the accidental touches and sliding of two adjacent buttons at the same time, thereby achieving a more comprehensive prevention of accidental touches and is more suitable for specific customer groups with a higher accidental touch rate at the knuckles.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-Figure 8 , the present invention provides the following technical solutions: Embodiment 1: In this embodiment, in order to solve the problems existing in the prior art, the following solution is disclosed: Figure 1-Figure 3As shown, it includes a shell 1 and a button 2 arranged above the shell 1 and for pressing. After the button 2 moves, it contacts the trigger module 3 installed on the circuit board 4 in the shell 1 and generates trigger information, and the information is processed by the micro-control module 5 on the circuit board 4. The movement of the button 2 includes non-vertical movement and vertical movement. After the button 2 moves non-vertically and is located above the trigger module 3, it moves vertically and contacts the trigger module 3. The button 2 is installed in a cylinder 6, and the cylinder 6 moves in a vertically penetrating through groove 7 in the shell 1, and is guided by a guide mechanism arranged in the shell 1 to drive the contact part 10 in the button 2 to move vertically by itself, wherein the contact part 10 is slidably installed under the cylinder 6 through a longitudinally distributed slide rod 11, and the guide mechanism includes a guide rail 8 with an internal groove and a vertical spacing, and the guide rail 8 is divided into a horizontal section and an arc section connecting the high and low horizontal sections, wherein the low horizontal section The trigger module 3 is located below. A roller 9 fits into the groove in the guide rail 8. The roller 9 is connected to the contact portion 10 through a rod, and the rod passes through the spacing gap between the upper and lower guide rails 8. The present solution solves the problem of possible accidental touches from a structural level. When the function needs to be triggered by a remote control key and a signal is transmitted through short-range wireless communication, the button 2 and the cylinder 6 for installing the button 2 can be directly slid by fingers in the slide groove provided on the shell 1, and the contact portion 10 arranged below the cylinder 6 will move horizontally synchronously, and synchronously with it, the rollers 9 connected on both sides of the contact portion 10 will move synchronously in the guide rail 8. When it moves to the arc section and the low-position horizontal section, the position of the roller 9 will also change from high to low, and the contact portion 10 will also pull the slide rod 11 downward at the same time and gradually contact the trigger module 3. In this way, accidental touches caused by simple pressing actions can be effectively avoided.

[0017] Also because the volume of the remote control key end is limited, downstream automobile manufacturers often require that the key buttons can trigger different functions by pressing in combination. For example, pressing a certain button twice repeatedly within a set time period can trigger a function different from the original button. After the present embodiment has the above-mentioned sliding anti-mistouch function, it can also have the function of repeatedly triggering signals and generating other instructions, which is also achieved through the structural end. Specifically, Figure 2 and Figure 4As shown, the vertical projection point of the trigger module 3 on the guide rail 8 is located between the two ends of the low horizontal section of the guide rail 8, and the contact portion 10 is used to contact the trigger module 3 and generate a specified signal. When the contact portion 10 moves to the low horizontal section and returns to the initial high horizontal section position, due to the design of the above scheme, the contact portion 10 can contact the trigger module 3 twice when it moves and quickly rebounds. In addition to saving user time and operating steps in terms of operational logic, this design scheme can also avoid users from accidentally triggering multiple instructions to contact the trigger module 3 at high frequency without their own will by appropriately increasing the contact resistance between the trigger module 3 and the contact portion 10.

[0018] Embodiment 2: Based on the above embodiment, this embodiment further discloses a scheme for automatically cleaning the key operating surface or cooling the key internal circuit by airflow, as shown in the following example. Figure 5 As shown, an air hole 13 is opened on the surface of the cylinder 6, and the air hole 13 is connected to an air supply mechanism. The air hole 13 is located outside or inside the shell 1, wherein the air supply mechanism is used to generate airflow and blow it out from the air hole 13 when the contact part 10 is displaced. The air supply mechanism includes a valve plate 12 installed on the top of the sliding rod 11 and vertically sealed and slidably connected in the cylinder 6. The space formed by the lower end surface of the valve plate 12 and the bottom wall of the cylinder 6 is connected to the air hole 13. When the contact part 10 moves up and down, the valve plate 12 will be driven to move up and down synchronously inside the cylinder 6 through the sliding rod 11, and during the movement, the space pressure below the valve plate 12 changes accordingly, so the air hole 13 will eject airflow or produce a negative pressure adsorption effect accordingly. When the air hole 13 is located outside the shell 1, the airflow can clean the operating surface of the shell 1, and if it is located inside the shell 1, it can accelerate the airflow circulation in the circuit space inside the shell 1.

[0019] Embodiment 3: In this embodiment, another method for preventing accidental touch based on the sliding operation is disclosed. Whether this method is actually put into production depends on whether the key needs to be used for a specific customer group. It cannot be used as the only method for preventing accidental touch of the present invention. For details, please refer to Figure 6-Figure 8The back of the contact portion 10 is connected to the top of the connecting rope 14, and the bottom of the connecting rope 14 is connected to the front of the circular plate 15, and the back of the circular plate 15 is connected to the inner wall of the housing 1 through the elastic member 16. The front edge of the circular plate 15 is also in contact with the surface of the limiting plate 17, wherein the middle section of the limiting plate 17 is used for rotation and installation in the housing 1, and the fronts of the two adjacent circular plates 15 are in contact with the two end surfaces of the same limiting plate 17. Under normal conditions, when the user slides one of the buttons 2, the contact portion 10 below it will pull the circular plate 15 to move through the connecting rope 14, and one end of the limiting plate 17 is moved by the circular plate 15. Normal traction movement, while the other end of the limiting plate 17 compresses the adjacent circular plate 15 and compresses the elastic member 16 to deform due to the lever principle, and the corresponding cylinder 6 of the compressed circular plate 15 will move a certain distance toward the edge of the shell 1 at the initial position, thereby ensuring the normal movement of the other operated cylinder 6. Similarly, the connecting rope 14 can also be set to a rope structure with a certain elasticity or tensile deformation. Therefore, when the user slides the two cylinders 6 at the same time in the case of misoperation, they will not be able to move due to the restriction that the two ends of the limiting plate 17 cannot deflect in one direction at the same time, thereby achieving the effect of preventing accidental touch.

[0020] Embodiment 4: The anti-mistouch function includes a button module and a micro-control module built into the fuselage. The button module includes multiple buttons, each button corresponds to a corresponding function trigger module in the micro-control module, wherein the micro-control module also includes a mistouch judgment unit. The micro-control unit is used to transmit and register the information triggered by the function trigger module after the button is pressed to the automobile terminal via the short-range wireless transmission module, wherein the mistouch judgment unit is used to filter out the trigger information that is judged to be mis-touched.

[0021] The false touch determination unit determines the false touch signal in a manner of intercepting or preventing the false touch signal from being triggered, wherein two or more key modules cause the information generated by the function trigger module to be determined as a false touch signal.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
