Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] This utility model provides a vehicle window lift controller, the structure of which is as follows: Figure 1 - Figure 3 As shown, it includes a housing 1, a buffer rod 2, a circuit board 3, and wires 4.

[0027] The housing 1 is provided with a clearance hole 11 for the wire 4 to pass through.

[0028] The buffer rod 2 includes a first rod body 21, a second rod body 22, and a spring 23. The first rod body 21 is connected to the housing 1, the second rod body 22 is slidably connected to the first rod body 21, one end of the spring 23 is connected to the first rod body 21, and the other end of the spring 23 is connected to the second rod body 22.

[0029] The circuit board 3 is mounted on the second rod 22.

[0030] One end of the wire 4 passes through the clearance hole 11 and is connected to the circuit board 3, and the other end of the wire 4 is connected to the switch.

[0031] During use, when the mining vehicle experiences strong vibrations, the housing 1, as the external support structure, bears the impact first. The spring 23 of the buffer rod 2 absorbs the vibration energy through elastic deformation, converting the vibration into the elastic potential energy of the spring 23. The second rod 22 moves linearly within the sliding groove of the first rod 21, creating a damping effect and further dissipating the vibration energy. The preload of the spring 23 ensures that the second rod 22 is in its initial equilibrium position when there is no vibration, preventing rigid collisions between the circuit board 3 and the housing 1. The dynamic stiffness variation characteristics of the spring 23 effectively avoid the resonance zone, preventing amplitude amplification. When the wire 4 enters the housing 1 through the clearance hole 11, its connection point with the second rod 22 moves synchronously with the circuit board 3, preventing relative displacement between the wire 4 and the fixed end and reducing the risk of wire 4 breakage.

[0032] In this invention, when a mining vehicle generates strong vibrations, the shell 1, as an external support structure, first bears the impact, and the second rod 22 moves linearly within the sliding groove of the first rod 21, forming a damping effect, further dissipating vibration energy and reducing the possibility of joint loosening.

[0033] For easier disassembly and assembly of housing 1, please refer to... Figure 1 In a preferred embodiment, the housing 1 includes an upper housing 12, a lower housing 13, and a fixing component 14. The upper housing 12 and the lower housing 13 abut together, and the fixing component 14 is used to fix the upper housing 12 and the lower housing 13 together. The clearance hole 11 is provided on the upper housing 12, and the buffer rod 2 is connected to the upper housing 12.

[0034] During use and installation, the upper shell 12 and the lower shell 13 abut together to form a positioning, and the upper shell 12 and the lower shell 13 are fixed together using the fixing component 14; during disassembly, the restriction of the fixing component 14 is released, and the upper shell 12 and the lower shell 13 can be separated, making disassembly and assembly convenient.

[0035] To improve the explosion-proof performance of the controller, please refer to... Figure 2 In a preferred embodiment, the housing 1 further includes an explosion-proof plate 15, which is located between the upper housing 12 and the lower housing 13, with both sides of the explosion-proof plate 15 abutting against the upper housing 12 and the lower housing 13 respectively.

[0036] When in use, the explosion-proof plate 15 is made of high-strength explosion-proof metal material, which has extremely strong explosion resistance. When an explosion occurs due to sparks generated inside the window controller caused by electrical faults or other reasons, the explosion-proof plate 15 can effectively block the high-temperature flames and shock waves generated by the explosion from spreading outward, thus preventing a larger safety accident.

[0037] To secure the upper shell 12 and the lower shell 13 together, please refer to... Figure 2In a preferred embodiment, the fixing component 14 includes a screw 141, the lower shell 13 is provided with a first through hole 142, the explosion-proof plate 15 is provided with a second through hole 143, the upper shell 12 is provided with a screw groove 144, the screw 141 passes through the first through hole 142 and the second through hole 143, and the screw 141 is threaded into the screw groove 144.

[0038] In use, screws 141 pass sequentially through the first through hole 142 of the lower shell 13 and the second through hole 143 of the explosion-proof plate 15, and are finally threaded into the screw groove 144 of the upper shell 12, tightly connecting the upper shell 12, the explosion-proof plate 15, and the lower shell 13 into a whole. This effectively prevents the components of the shell 1 from loosening or shifting when the mining vehicle faces complex working conditions such as strong vibrations and bumps during operation.

[0039] To further reduce the possibility of screw 141 loosening, please refer to Figure 3 In a preferred embodiment, the fixing component 14 further includes an elastic washer 145, which is sleeved on the screw 141, and the two sides of the elastic washer 145 abut against the lower shell 13 and the nut of the screw 141, respectively.

[0040] When in use, mining vehicles face continuous strong vibrations. The elastic washer 145 can generate elastic deformation during vibration, and always apply pressure to the screw 141 nut and the lower shell 13, effectively preventing the screw 141 from loosening due to vibration.

[0041] To secure circuit board 3, please refer to... Figure 3 In a preferred embodiment, the controller further includes a locking component 5, which includes a positioning rod 51 and a nut 52. The positioning rod 51 is connected to the second rod body 22. The circuit board 3 is provided with a positioning hole 53 for the positioning rod 51 to pass through. The nut 52 is threadedly connected to the positioning rod 51 and abuts against the circuit board 3.

[0042] In use, the positioning rod 51 passes through the positioning hole 53 on the circuit board 3, which can accurately position the circuit board 3 in the planar direction and restrict its horizontal movement. After the nut 52 is tightened, it abuts against the circuit board 3, firmly fixing the circuit board 3 to the second rod 22 and preventing it from being displaced in the vertical direction.

[0043] To reduce the possibility of nut 52 loosening, please refer to... Figure 3 In a preferred embodiment, the locking component 5 further includes an anti-loosening block 54, the positioning rod 51 is provided with a first slot 55, the nut 52 is provided with a second slot 56, and the anti-loosening block 54 is engaged in the first slot 55 and the second slot 56.

[0044] During use, the anti-loosening block 54 simultaneously engages with the first slot 55 of the positioning rod 51 and the second slot 56 of the nut 52, forming a mechanical limit and preventing the nut 52 from rotating relative to the positioning rod 51. This ensures that the circuit board 3 remains firmly fixed under long-term and complex working conditions.

[0045] To make wire 4 move synchronously with circuit board 3, please refer to... Figure 3 In a preferred embodiment, the controller further includes a cable tie 6 and a positioning ring 7. The cable tie 6 includes a strap body 61 and a buckle 62. The buckle 62 is connected to the strap body 61. The positioning ring 7 is connected to the upper shell 12. The strap body 61 passes through the positioning ring 7. The cable tie 6 is used to fix the wire 4 inside the shell 1 so that there is a stretch allowance between the wire 4 and the circuit board 3.

[0046] During use, cable ties 6 secure the wire 4 to the positioning ring 7 via the locking buckle 62, preventing the wire 4 from shaking or shifting in the strong vibration environment of vehicle operation, and reducing the risk of loosening or detachment of the wire 4 at the connector with the circuit board 3 due to pulling. When securing the wire 4, the cable ties 6 leave an appropriate amount of flexibility between the wire 4 and the circuit board 3. When the relative displacement of components occurs due to vehicle bumps, the wire 4 can move freely within the flexibility range, avoiding breakage of the wire 4 or damage to the solder joints due to excessive stretching, thus extending the service life of the wire 4.

[0047] To reduce the possibility of damage to wire 4, please refer to Figure 3 In a preferred embodiment, the controller further includes an elastic layer 63, which is made of foam and has a thickness of 1 mm. The elastic layer 63 is connected to the belt body 61 and abuts against the wire 4.

[0048] During use, the strong vibrations generated by mining vehicles can easily damage the conductor 4. The elastic layer 63 has good elasticity and flexibility, which can effectively absorb vibration energy. This reduces problems such as breakage of the internal metal wires and wear of the outer sheath caused by vibration, thus extending the service life of the conductor 4.

[0049] To reduce the possibility of wire 4 detaching, please refer to... Figure 3 In a preferred embodiment, the controller further includes an anti-slip layer 64, which is made of rubber and has a thickness of 1 mm. The anti-slip layer 64 is connected to the elastic layer 63 and abuts against the wire 4.

[0050] When in use, the anti-slip layer 64 is made of a material with a high coefficient of friction. Under the same fastening force, the sliding resistance of the wire 4 increases, effectively preventing the wire 4 from loosening due to vibration.

[0051] To better understand this utility model, the following is combined with... Figure 1 - Figure 3The working principle of a vehicle window lift controller according to the present invention is described in detail as follows: When a mining vehicle generates strong vibrations, the housing 1, as an external support structure, first bears the impact. The spring 23 of the buffer rod 2 absorbs the vibration energy through elastic deformation, converting the vibration into the elastic potential energy of the spring 23. The second rod 22 moves linearly within the sliding groove of the first rod 21, forming a damping effect and further dissipating the vibration energy. The preload of the spring 23 ensures that the second rod 22 is in its initial equilibrium position when there is no vibration, avoiding rigid collision between the circuit board 3 and the housing 1. The dynamic stiffness change characteristics of the spring 23 can effectively avoid the resonance zone and prevent amplitude amplification. When the wire 4 enters the housing 1 through the clearance hole 11, the connection point with the second rod 22 moves synchronously with the circuit board 3, avoiding relative displacement between the wire 4 and the fixed end, and reducing the risk of wire 4 breakage.

[0052] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
