Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing brackets, in particular to a shock-absorbing bracket for a wire harness assembly of a new energy vehicle. Background Technique

[0002] In the production and processing of new energy vehicles, various high-strength wire harnesses are often required. The vehicle wire harness is the network main body of the vehicle circuit, and the vehicle circuit is a circuit composed of multiple wire harnesses connecting the entire vehicle body and various electrical components. The circuit is an important structure for controlling the entire vehicle.

[0003] In the existing new energy vehicle wire harness brackets, during use, the base is mostly connected to the vehicle frame by screws, and then the wire harness is clamped on the bracket for fixation. However, due to the lack of a buffer structure in the existing wire harness brackets, it may cause the bracket to shake when the vehicle shakes or vibrates, resulting in the bracket dragging the wire harness during the shaking process, causing the wire harness to become loose or broken in connection, affecting the normal use of the wire harness. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a shock-absorbing bracket for a wire harness assembly is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A shock-absorbing bracket for a new energy vehicle wire harness assembly, including a base. A support device is arranged on one side of the base, and an adjusting device is arranged on one side of the base. The support device includes a spring and a circular tube. The wire harness is inserted into the circular tube for positioning, and then the telescopic movement and reaction force of the spring are used to assist in supporting the circular tube, so that the circular tube can move reciprocally under the vibration of the vehicle to buffer the forces on the circular tube and the wire harness.

[0006] The effects achieved by the above components are as follows: When the vehicle vibrates or shakes, the circular tube moves reciprocally under the action of the spring following the vibration or shaking of the vehicle, and the circular tube moves when it is about to drag the wire harness, thereby achieving the force buffering effect and reducing the situation that the circular tube drags the wire harness when the vehicle vibrates or shakes, resulting in damage to the wire harness.

[0007] Preferably, the support device includes a screw rod, the screw rod is fixedly connected to the base, a ring is sleeved on the surface of the screw rod, one side of the ring is fixedly connected to a spring, the spring is sleeved on the surface of the screw rod, the other end of the spring is fixedly connected to the base, one side of the ring is fixedly connected to a connecting rod, the connecting rod is fixedly connected to a circular tube at the end far away from the ring, and a rubber pad is fixedly connected to the inner wall of the circular tube, and the surface of the rubber pad is arc-shaped.

[0008] The effects achieved by the above components are as follows: By setting up the support device, the wire harness is first inserted and passed through the inside of the round tube for positioning, so that the rubber pad separates the wire harness from the inner wall of the round tube. When the vehicle vibrates or shakes, the base moves along with the vehicle, causing the round tube to move under the telescopic action of the spring. At the same time, under the limiting action of the wire harness on the round tube, when the round tube drags the wire harness during the movement process, the round tube moves under the telescopic action of the spring, making the round tube an active support that can move along with the wire harness, reducing the pulling force of the round tube on the wire harness, and reducing the situation where the wire harness breaks or the connection becomes loose due to the pulling force generated when the vehicle vibrates or shakes during use, thereby improving the usage efficiency of the wire harness.

[0009] Preferably, a plurality of ventilation holes are provided on the surface of the round tube, and the plurality of ventilation holes are arranged at equal distances.

[0010] The effects achieved by the above components are as follows: By setting up the ventilation holes, the ventilation holes can increase the air flow and reduce the situation where the temperature of the contact surface between the round tube and the wire harness is relatively high due to the tight contact.

[0011] Preferably, a threaded hole ring is threadedly connected to the surface of the screw rod. One side of the threaded hole ring is fixedly connected with an operation ring. A plurality of anti-slip protrusions are provided on the surface of the operation ring. The surface of the threaded hole ring is larger than the inner wall of the ring. The operation ring is sleeved on the surface of the screw rod.

[0012] The effects achieved by the above components are as follows: By setting up the threaded hole ring, first manually rotate the operation ring, so that the operation ring drives the threaded hole ring to move up and down along the surface of the screw rod, causing the threaded hole ring to squeeze the surface of the ring and intercept and limit the ring, so that the ring and the round tube can be intercepted at a specified height position, enabling personnel to adjust the installation height of the round tube and the wire harness, thereby improving the installation efficiency of the wire harness.

[0013] Preferably, a damping rod is fixedly connected to one side of the connecting rod, and the surface of the damping rod is higher than the surface of the round tube.

[0014] The effects achieved by the above components are as follows: By setting up the damping rod, when the round tube moves under force, the damping rod can assist in intercepting the round tube, reducing the situation of collision between the round tube and the base.

[0015] Preferably, a rubber block is fixedly connected to the end of the damping rod away from the connecting rod, and the surface of the rubber block is circular.

[0016] The effects achieved by the above components are as follows: By setting up the rubber block, the rubber block can block between the damping rod and the base, reducing the situation of wear on their surfaces when the damping rod collides with the base.

[0017] Preferably, one end of the screw rod away from the base is fixedly connected with a limit plate, and the surface of the limit plate is larger than the inner wall of the operation ring.

[0018] The effect achieved by the above components is that by setting the limit plate, the limit plate can intercept the operation ring and the screw hole ring during the movement process, reducing the situation that the screw hole ring disengages from the surface of the screw rod during the movement process.

[0019] Preferably, the adjusting device includes a rectangular hole opened on one side of the base. A round hole block is slidably connected to the inner wall of the rectangular hole. A bolt is provided inside the round hole block. A gasket is sleeved on the surface of the bolt. The nut position of the bolt is larger than the inner wall of the gasket. One side of the gasket is fixedly connected with a cylindrical block. A plurality of round grooves are opened on one side of the base close to the rectangular hole. The size and shape of the surface of the cylindrical block are adapted to the size and shape of the inner wall of the round groove.

[0020] The effect achieved by the above components is that by setting the adjusting device, first manually move the round hole block so that the round hole block slides left and right along the inside of the rectangular hole. When the round hole block moves to the specified position, manually move the gasket so that the gasket drives the cylindrical block to move. When the cylindrical block moves to the position where it is inserted into the round groove, make the inner wall of the gasket coincide with the inner wall of the round hole block. At this time, insert the bolt into the gasket and the round hole block and rotate the bolt with a tool so that the bolt rotates to the position inside the screw hole opened on the vehicle frame to fix the positions of the gasket and the round hole block, thereby achieving the stable connection between the base and the vehicle frame and the adjustment of the installation position of the base, reducing the deviation between the screw hole position on the vehicle frame and the hole position on the base, which affects the normal installation of the base, and improving the installation convenience and flexibility of the base.

[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0022] In the present utility model, by setting the support device, the wire harness can be limited, and at the same time, it can become a movable bracket that moves along with the wire harness, reducing the pulling force of the round tube on the wire harness, and reducing the situation that the wire harness breaks or the connection becomes loose due to the pulling force generated when the vehicle vibrates or shakes during use, improving the use efficiency of the wire harness. Among them, the rubber pad clamping the cable can reduce the expansion of the cable vibration. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0028] Refer to Figures 1-4 As shown, this embodiment discloses a shock-absorbing bracket for a new energy vehicle wire harness assembly, including a base 1. A support device 2 is provided on one side of the base 1, and an adjusting device 3 is provided on one side of the base 1. The support device 2 includes a spring 23 and a round tube 25. The wire harness is inserted into the round tube 25 for limiting, and then the telescopic movement and reaction force of the spring 23 are used to assist in supporting the round tube 25, so that the round tube 25 can move reciprocally under the vibration of the vehicle to buffer the force on the round tube 25 and the wire harness. When the vehicle vibrates or shakes, the round tube 25 moves reciprocally under the action of the spring 23 following the vibration or shake of the vehicle, so that the round tube 25 moves when it is about to drag the wire harness, thereby achieving the force buffering effect and reducing the situation that the round tube 25 drags the wire harness when the vehicle vibrates or shakes, resulting in wire harness damage.

[0029] Refer to Figure 2 and Figure 3As shown in the figure, this embodiment discloses that the support device 2 includes a screw rod 21, the screw rod 21 is fixedly connected to the base 1, a circular ring 22 is sleeved on the surface of the screw rod 21, one side of the circular ring 22 is fixedly connected to a spring 23, the spring 23 is sleeved on the surface of the screw rod 21, and the other end of the spring 23 is fixedly connected to the base 1. One side of the circular ring 22 is fixedly connected to a connecting rod 24, the end of the connecting rod 24 far from the circular ring 22 is fixedly connected to a circular tube 25, and a rubber pad 26 is fixedly connected to the inner wall of the circular tube 25. The surface of the rubber pad 26 is arc-shaped. By setting the support device 2, first insert and pass the wire harness through the inside of the circular tube 25 for positioning, so that the rubber pad 26 separates the wire harness from the inner wall of the circular tube 25. When the vehicle vibrates or shakes, the base 1 moves with the vehicle, so that the circular tube 25 moves under the telescopic action of the spring 23. At the same time, under the limiting action of the wire harness on the circular tube 25, when the circular tube 25 drags the wire harness during the movement process, the circular tube 25 moves under the telescopic action of the spring 23, so that the circular tube 25 becomes a movable bracket that can move along with the wire harness, reducing the pulling force of the circular tube 25 on the wire harness, and reducing the situation that the wire harness breaks or the connection becomes loose due to the pulling force generated when the vehicle vibrates or shakes during use, improving the use efficiency of the wire harness.

[0030] Referring to Figure 2 and Figure 3 As shown in the figure, this embodiment discloses that a plurality of ventilation holes 27 are opened on the surface of the circular tube 25, and the plurality of ventilation holes 27 are arranged at equal distances. By setting the ventilation holes 27, the ventilation holes 27 can increase the air flow and reduce the situation that the temperature of the fitting degree is relatively high due to the relatively tight fitting between the circular tube 25 and the wire harness. A screw hole ring 28 is threadedly connected to the surface of the screw rod 21, one side of the screw hole ring 28 is fixedly connected to an operation ring 29, and a plurality of anti-slip protrusions are provided on the surface of the operation ring 29. The surface of the screw hole ring 28 is larger than the inner wall of the circular ring 22, and the operation ring 29 is sleeved on the surface of the screw rod 21. By setting the screw hole ring 28, first manually rotate the operation ring 29, so that the operation ring 29 drives the screw hole ring 28 to move up and down along the surface of the screw rod 21, so that the screw hole ring 28 presses against the surface of the circular ring 22 and intercepts and limits the circular ring 22, so that the circular ring 22 and the circular tube 25 can be intercepted at a specified height position, so that the installation height of the circular tube 25 and the wire harness can be adjusted by personnel, improving the installation efficiency of the wire harness.

[0031] Referring to Figure 2 and Figure 3As shown in the figure, this embodiment discloses that a damping rod 211 is fixedly connected to one side of the connecting rod 24. The surface of the damping rod 211 is higher than the surface of the circular tube 25. By providing the damping rod 211, when the circular tube 25 moves under force, the damping rod 211 can assist in intercepting the circular tube 25, reducing the collision between the circular tube 25 and the base 1. One end of the damping rod 211 away from the connecting rod 24 is fixedly connected with a rubber block 212. The surface of the rubber block 212 is circular. By providing the rubber block 212, the rubber block 212 can block between the damping rod 211 and the base 1, reducing the wear on the surface when the damping rod 211 collides with the base 1 and can also perform shock absorption. One end of the screw 21 away from the base 1 is fixedly connected with a limiting plate 210. The surface of the limiting plate 210 is larger than the inner wall of the operation ring 29. By providing the limiting plate 210, the limiting plate 210 can intercept the operation ring 29 and the screw hole ring 28 during the moving process, reducing the situation that the screw hole ring 28 detaches from the surface of the screw 21 during the moving process.

[0032] Referring to Figure 4 As shown in the figure, this embodiment discloses that the adjusting device 3 includes a rectangular hole 31 opened on one side of the base 1. The inner wall of the rectangular hole 31 is slidably connected with a round hole block 33. A bolt 34 is provided inside the round hole block 33. A gasket 35 is sleeved on the surface of the bolt 34. The nut position of the bolt 34 is larger than the inner wall of the gasket 35. One side of the gasket 35 is fixedly connected with a cylindrical block 36. A plurality of circular grooves 32 are opened on one side of the base 1 close to the rectangular hole 31. The size and shape of the surface of the cylindrical block 36 are adapted to the size and shape of the inner wall of the circular groove 32. By providing the adjusting device 3, first manually move the round hole block 33 so that the round hole block 33 slides left and right along the inside of the rectangular hole 31. When the round hole block 33 moves to the specified position, manually move the gasket 35 so that the gasket 35 drives the cylindrical block 36 to move. When the cylindrical block 36 moves to the position where it is inserted into the circular groove 32, the inner wall of the gasket 35 coincides with the inner wall of the round hole block 33. At this time, insert the bolt 34 into the gasket 35 and the round hole block 33 and rotate the bolt 34 with a tool so that the bolt 34 rotates to the position inside the screw hole opened on the vehicle frame to fix the positions of the gasket 35 and the round hole block 33, thereby achieving the stable connection between the base 1 and the vehicle frame and the adjustment of the installation position of the base 1, reducing the deviation between the screw hole position on the vehicle frame and the hole position on the base 1, which affects the normal installation of the base 1, and improving the installation convenience and flexibility of the base 1.

[0033] Working principle: First, manually move the round-hole block 33 so that the round-hole block 33 slides left and right along the inside of the rectangular hole 31. When the round-hole block 33 moves to the specified position, manually move the gasket 35 so that the gasket 35 drives the cylindrical block 36 to move. When the cylindrical block 36 moves to the position where it is snapped into the round groove 32, make the inner wall of the gasket 35 coincide with the inner wall of the round-hole block 33. At this time, insert the bolt 34 into the gasket 35 and the round-hole block 33 and rotate the bolt 34 with a tool so that the bolt 34 rotates to the position inside the screw hole opened in the vehicle frame to fix the positions of the gasket 35 and the round-hole block 33, thereby achieving the stable connection between the base 1 and the vehicle frame and adjusting the installation position of the base 1. At the same time, achieve the rapid assembly of the support device 2 and the vehicle frame. At this time, insert the wire harness and pass it through the inside of the round tube 25 for limiting, so that the rubber pad 26 separates the wire harness from the inner wall of the round tube 25. When the vehicle vibrates or shakes, make the base 1 move with the vehicle, so that the round tube 25 moves under the telescopic action of the spring 23. At the same time, under the limiting action of the wire harness on the round tube 25, when the round tube 25 drags the wire harness during the movement process, make the round tube 25 move under the telescopic action of the spring 23, so that the round tube 25 becomes a movable bracket that can move along with the wire harness, reducing the pulling force of the round tube 25 on the wire harness and completing the force buffering of the wire harness.
