Description

Technical Field

[0001] This invention relates to the field of electric vehicle controller technology, specifically to an electric vehicle controller with a shock-absorbing and buffering structure. Background Technology

[0002] A controller is a master control device that controls the starting, speed regulation, braking, and reversing of a motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. It consists of a program counter, instruction register, instruction decoder, timing generator, and operation controller. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire computer system. The controller is mainly used to control the starting, running, forward and reverse, speed, and stopping of the micro motor of the electric vehicle, as well as other electronic components of the electric vehicle. It is like the brain of the electric vehicle and is an important component.

[0003] Existing controllers are directly installed and used, but they can be damaged by external forces, especially when traveling on uneven roads. Bumps in the road can also cause the controller to be squeezed, and once the controller is damaged, the entire vehicle cannot move, requiring immediate replacement, which can cause inconvenience to users. To address this, we propose an electric vehicle controller with a shock-absorbing and buffering structure. Summary of the Invention

[0004] The purpose of this invention is to provide an electric vehicle controller with a shock-absorbing and buffering structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electric vehicle controller with a shock-absorbing and buffering structure, comprising a housing, side panels, an upper panel, a protective shell, and a controller body. A first U-shaped frame is fixedly connected to the bottom end of the upper panel. Two side panels are provided, and a second U-shaped frame is fixedly connected to the opposite side of each side panel. A movable rod passes through the second U-shaped frame, and a spring is sleeved on the surface of the movable rod. One end of the spring overlaps with the side of the second U-shaped frame. A connecting groove is fixedly connected above the second U-shaped frame, and a connecting element is provided inside the connecting groove. The controller body has a micro motor at its upper end. The output shaft of the micro motor is fixedly connected to a drive wheel, and a driven wheel meshes with the surface of the drive wheel. A threaded rod is fixedly connected to the side of the driven wheel via a rotating shaft. A threaded block is threadedly connected to the surface of the threaded rod. A contact switch is fixedly connected to the surface of the protective shell, and the contact switch is electrically connected to the micro motor.

[0006] Preferably, the bottom end of the housing is provided with a first sliding groove, and a first slider is provided inside the first sliding groove. The surface of the first slider is fixedly connected to the bottom end of the side baffle.

[0007] Preferably, the upper end of the housing is provided with a second sliding groove, and a second slider is provided inside the second sliding groove. The surface of the second slider is fixedly connected to the upper end of the side baffle.

[0008] Preferably, a first limiting groove is vertically formed on the side of the housing, and a first limiting block is provided inside the first limiting groove. The side of the first limiting block is fixedly connected to the side of the first U-shaped frame.

[0009] Preferably, a second limiting groove is laterally opened on the side of the housing, and a second limiting block is provided inside the second limiting groove. The side of the second limiting block is fixedly connected to the side of the second U-shaped frame.

[0010] Preferably, the threaded block is disposed inside the protective shell, and the surface of the threaded block is flush with the surface of the protective shell. A bearing is sleeved on the surface of the rotating shaft, and a fixing block is fixedly connected to the side of the bearing. The side of the fixing block is fixedly connected to the protective shell.

[0011] Preferably, a third limiting groove is provided inside the protective shell, and a third limiting block is provided inside the third limiting groove. The side of the third limiting block is fixedly connected to the surface of the threaded block.

[0012] Preferably, the side baffle overlaps with the side of the housing, the upper baffle overlaps with the upper surface of the housing, the controller body is provided inside the housing, a protective shell is fixedly connected to the upper end of the housing, and the distances from the side baffle and the upper baffle to the surface of the protective shell are equal.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention, by setting side and top baffles, when subjected to slight external impact, will cause the side and top baffles to move along the movable rod, thereby compressing the springs on the surface of the movable rod and using the spring force to push the side and top baffles back. Under the force, it can play a certain buffering role, and can use the spring force to prevent external force from directly squeezing and damaging the controller body. It can effectively provide the first protection for the controller body and increase the shock absorption effect of the controller body surface.

[0015] This invention, by setting a contact switch and a micro motor, enables the threaded block inside the protective shell to be quickly pushed out through the linkage between the driving wheel and three driven wheels after the side baffle and the top baffle contact the contact switch. This directly supports the side baffle and the top baffle, preventing the side baffle and the top baffle from continuing to squeeze the controller body, thereby achieving secondary protection. This effectively avoids damage to the controller body caused by excessive pressure and improves the protection of the controller body. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-7This invention provides a technical solution: an electric vehicle controller with a shock-absorbing and buffering structure, comprising a housing 1, side baffles 2, an upper baffle 3, a protective shell 11, and a controller body 10. A first U-shaped frame 13 is fixedly connected to the bottom end of the upper baffle 3. There are two side baffles 2, and a second U-shaped frame 15 is fixedly connected to the opposite side of each side baffle 2. A movable rod 18 passes through the second U-shaped frame 15, and a spring 17 is sleeved on the surface of the movable rod 18. One end of the spring 17 overlaps with the side of the second U-shaped frame 15. A connecting groove 20 is fixedly connected above the second U-shaped frame 15. The unit is equipped with a connecting block 21, and a connecting rod 14 is fixedly connected above the connecting block 21. A movable rod 18 is provided between the first U-shaped frame 13 and the connecting rod 14, and a spring 17 sleeved on the surface of the movable rod 18 overlaps with the surfaces of the first U-shaped frame 13 and the connecting rod 14 respectively. By setting the side baffle 2 and the upper baffle 3, when subjected to a slight external impact, the side baffle 2 and the upper baffle 3 will move on the movable rod 18, thereby squeezing the spring 17 on the surface of the movable rod 18, and using the elastic force of the spring 17 to push the side baffle 2 and the upper baffle 3 back, which can play a certain buffering role under the force. The spring 17 can be used to prevent external forces from directly squeezing and damaging the controller body 10, effectively providing initial protection for the controller body 10 and increasing the shock absorption effect on the surface of the controller body 10. A micro motor 22 is provided at the upper end of the controller body 10. The output shaft of the micro motor 22 is fixedly connected to the drive wheel 23, and the surface of the drive wheel 23 is engaged with the driven wheel 31. A threaded rod 26 is fixedly connected to the side of the driven wheel 31 through the rotating shaft 30. A threaded block 27 is threadedly connected to the surface of the threaded rod 26. A contact switch is fixedly connected to the surface of the protective shell 11. 12. The contact switch 12 is electrically connected to the micro motor 22. By setting the contact switch 12 and the micro motor 22, after the side baffle 2 and the upper baffle 3 contact the contact switch 12, the drive wheel 23 and the three driven wheels 31 can quickly push out the threaded block 27 inside the protective shell 11 through the linkage, and directly support the side baffle 2 and the upper baffle 3, so as to prevent the side baffle 2 and the upper baffle 3 from continuing to squeeze the controller body 10, thereby achieving secondary protection. This can effectively prevent excessive pressure from damaging the controller body 10 and improve the protection of the controller body 10.

[0026] Specifically, a first sliding groove 5 is provided at the bottom of the housing 1, and a first slider 4 is provided inside the first sliding groove 5. The surface of the first slider 4 is fixedly connected to the bottom of the side baffle 2. A second sliding groove 7 is provided at the top of the housing 1, and a second slider 6 is provided inside the second sliding groove 7. The surface of the second slider 6 is fixedly connected to the top of the side baffle 2. By setting the first slider 4 and the second slider 6, the side baffle 2 can be assisted to avoid tilting above the side baffle 2. It can also cooperate with the side baffle 2 to move relative to each other, and can also play a certain role in stress relief and shock absorption.

[0027] Specifically, a first limiting groove 8 is vertically opened on the side of the housing 1, and a first limiting block 16 is provided inside the first limiting groove 8. The side of the first limiting block 16 is fixedly connected to the side of the first U-shaped frame 13. A second limiting groove 9 is horizontally opened on the side of the housing 1, and a second limiting block 19 is provided inside the second limiting groove 9. The side of the second limiting block 19 is fixedly connected to the side of the second U-shaped frame 15. The first limiting block 16 and the second limiting block 19 can cooperate with the up and down movement of the first U-shaped frame 13 and the left and right movement of the second U-shaped frame 15 to ensure the limiting during movement and avoid damage to the controller body 10 caused by the side baffle 2 and the upper baffle 3.

[0028] Specifically, the threaded block 27 is set inside the protective shell 11, and the surface of the threaded block 27 is flush with the surface of the protective shell 11. The bearing 28 is sleeved on the surface of the rotating shaft 30, and a fixing block 29 is fixedly connected to the side of the bearing 28. The side of the fixing block 29 is fixedly connected to the protective shell 11.

[0029] Specifically, the protective shell 11 has a third limiting groove 24 inside, and a third limiting block 25 is provided inside the third limiting groove 24. The side of the third limiting block 25 is fixedly connected to the surface of the threaded block 27.

[0030] Specifically, the side baffle 2 overlaps with the side of the housing 1, the upper baffle 3 overlaps with the upper surface of the housing 1, the controller body 10 is located inside the housing 1, and the upper end of the housing 1 is fixedly connected to the protective shell 11. The side baffle 2 and the upper baffle 3 are equidistant from the surface of the protective shell 11. The side baffle 2 and the upper baffle 3, which are equidistant, can support the side baffle 2 and the upper baffle 3 immediately after the threaded block 27 is pushed out, so as to avoid damage to the controller body 10 at the bottom of the protective shell 11.

[0031] Working principle: In use, the entire device is installed in the designated position. When the left and right side baffles 2 and the upper baffle 3 are subjected to pressure, they will move to the left and right and downward respectively. Simultaneously, the upper baffle 3, under pressure, will cause the first U-shaped frame 13 at the bottom to press downward against the spring 17 on the surface of the movable rod 18 between the two connecting rods 14. The movement of the side baffles 2 will, through the second U-shaped frame 15, press against the spring 17 on the surface of the movable rod 18 between the two second U-shaped frames 15. At the same time, the third limiting groove 24 above the second U-shaped frame 15 will also move, sliding on the surface of the third limiting block 25. The side baffles 2 and the upper baffle 3 will also move with the help of the springs. The spring force of spring 17 pushes the side baffle 2 and the upper baffle 3 in the opposite direction to achieve reset. When the side baffle 2 and the upper baffle 3 are subjected to excessive pressure, the side baffle 2 and the upper baffle 3 will squeeze the contact switch 12 on the surface of the protective shell 11. After the contact switch 12 is activated, the micro motor 22 will start immediately and drive the drive wheel 23 to rotate. Through the meshing between the drive wheel 23 and the driven wheel 31, the driven wheel 31 drives the three threaded rods 26 to rotate via the rotating shaft 30, quickly pushing the corresponding three threaded blocks 27 out of the shell 1. The threaded blocks 27 support the side baffle 2 and the upper baffle 3, thereby protecting the controller body 10 at the bottom of the protective shell 11.
