Description

Technical Field

[0001] The utility model relates to the technical field of automobile controllers, in particular to an automobile controller and a control module. Background Art

[0002] In hot weather, when a car drives on a high-temperature road for a long time, the tire temperature will gradually rise, causing the internal tire pressure to increase. At this time, when the car tire pressure is too high and exceeds a certain range, it is easy to rupture when impacted, resulting in a tire blowout.

[0003] Generally speaking, when a car controller detects that the tire pressure is too high, it will display a warning message on the instrument panel to remind the driver that the tire is over-inflated. However, when the driver is already driving on a highway or has entered a road section with complex road conditions, it is not convenient to stop and deflate the tire.

[0004] Therefore, those skilled in the art provide an automobile controller and a control module to solve the problems raised in the above background technology. Utility Model Content

[0030] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0031] Please see the attached Figure 1-5 In an embodiment of the present utility model, a car controller includes a car tire 1, to which a controller body 2 is fixedly connected, and the controller body 2 is used to provide overpressure protection for the car tire 1;

[0032] The controller body 2 includes an upper shell 21 and a lower shell 22, the upper shell 21 and the lower shell 22 are fixedly connected and communicated, and the lower shell 22 is communicated with the automobile tire 1;

[0033] A micro electric cylinder 5 is fixedly connected to the upper shell 21, an output end of the micro electric cylinder 5 is connected to a piston rod 6, and one side of the piston rod 6 is fixedly connected to a pressure plate 7;

[0034] A support plate 16 is fixedly connected to the lower shell 22, and a connecting rod 9 is slidably connected to the middle of the support plate 16. A pushing rod 10 is fixedly connected to the bottom of the connecting rod 9. A ball valve 11 is movably connected to the bottom of the lower shell 22. The ball valve 11 is used to block or connect the lower shell 22 and the car tire 1. The pushing rod 10 and the ball valve 11 cooperate with each other. When the pressure of the car tire 1 is normal and the piston rod 6 of the micro-electric cylinder 5 does not drive the pressure plate 7 to move down and squeeze the connecting block 8, the pushing rod 10 and the ball valve 11 are not in contact. At this time, the ball valve 11 is under the internal pressure of the tire and the spiral Under the thrust of the support spring 20, it fits tightly with the limit seat 12 and is limited by the limit seat 12, which can prevent the gas in the tire from leaking. When the pressure of the car tire 1 is too high, the micro cylinder 5 drives the pressure plate 7 to move downward through the piston rod 6, and when squeezing the connecting block 8, it can drive the connecting rod 9 and the pushing rod 10 to move downward synchronously, and press the ball valve 11 to move downward, so that the connecting gap between the ball valve 11 and the limit seat 12 can discharge the excess gas in the car tire 1, complete the pressure relief, and effectively avoid the phenomenon of tire blowout caused by excessive pressure in the tire.

[0035] A connecting block 8 is fixedly connected to the connecting rod 9, and a tension spring 14 is fixedly connected between the connecting block 8 and the support plate 16 on the outside of the connecting rod 9. When the pressure in the tire drops to a set range, the micro-cylinder 5 drives the piston rod 6 and the pressure plate 7 to reset, and then the tension spring 14 releases the pressure, pushing the connecting block 8 to the top of the lower shell 22, and then the connecting rod 9 and the pushing rod 10 move up synchronously and separate from the ball valve 11. A groove 15 is provided on the top of the connecting block 8, and the groove 15 cooperates with the pressure plate 7. The groove 15 can position the pressure plate 7, which can improve the stability of the pressure plate 7 when pushing the connecting block 8. The bottom of the pushing rod 10 is set in an arc shape, which can better fit the curvature of the ball valve 11 and improve its stability in pushing the ball valve 11.

[0036] The bottom of the lower shell 22 is fixedly connected to the limit seat 12, and a support spring 20 is connected inside the limit seat 12. The support spring 20 is arranged in a spiral shape, and the diameter of the support spring 20 gradually increases from top to bottom. The ball valve 11 is connected above the support spring 20, and then the support spring 20 can effectively support the ball valve 11 and the limit seat 12 tightly. When the ball valve 11 moves downward, the support spring 20 is compressed. When the ball valve 11 is reset, the support spring 20 releases pressure and resets.

[0037] The power supply unit 3 and the control unit 4 are fixedly connected in the upper shell 21. The micro cylinder 5, the power supply unit 3 and the control unit 4 are electrically connected. The power supply unit 3 provides power to the control unit 4 and the micro cylinder 5. The control unit 4 can be connected to the Bluetooth in the car to display the internal pressure of the tire in real time and control the operation of the micro cylinder 5.

[0038] An opening 23 is provided at the bottom of the lower shell 22, and an arc-shaped stopper 24 is connected to the outside of the opening 23, which can further avoid the possibility of separation of the ball valve 11 and the support spring 20. The lower shell 22 is provided with multiple exhaust ports 13, and the multiple exhaust ports 13 are arranged at intervals. The exhaust ports 13 are all connected to a dustproof net 17, so that when the pressure is released, the multiple exhaust ports 13 can quickly discharge the gas in the tire. The dustproof net 17 can effectively prevent external dust from entering the lower shell 22 through the exhaust ports 13.

[0039] A guide groove 18 is fixedly connected to the bottom of the support plate 16, and the guide groove 18 is used to limit and guide the connecting rod 9. The support plate 16 and the guide groove 18 can effectively limit and guide the connecting rod 9 to avoid deviation during its movement.

[0040] A support base 19 is fixedly connected to the interior of the upper shell 21, and the micro electric cylinder 5 is fixedly connected to the top of the support base 19. The cross-section of the support base 19 is an inverted U-shape. The support base 19 guides and limits the pressure plate 7 inside, thereby ensuring the stability of the movement of the pressure plate 7.

[0041] The control module includes any one of the above-mentioned automobile controllers.
