Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness bracket technology, specifically a wiring harness bracket, wiring harness fixer, and fixing method for new energy vehicles. Background Technology

[0002] New energy vehicle wiring harness brackets are important structural components used to fix, protect and guide high-voltage and low-voltage wiring harnesses in vehicles. Their design must take into account requirements such as safety, lightweight, high temperature resistance and electromagnetic compatibility.

[0003] The harness bracket's binding force prevents the harness from wearing out or falling off due to vibration during vehicle operation. At the same time, the bracket also provides isolation protection to prevent wear when the harness comes into contact with the vehicle's metal edges or other parts.

[0004] Therefore, rigid brackets can be made of metal or engineering plastics to ensure the stability of the wiring harness. However, since high-frequency vibrations inevitably occur when a car is in motion, the vibrations not only increase the friction between the wiring harness and the bracket, but may also cause the clips or bolts of the rigid bracket to loosen, leading to the failure of the wiring harness restraint.

[0005] To address this, elastic supports can be used to provide a certain buffering effect during vibration, thereby reducing the force transmitted to the wire harness. However, the binding force provided by existing elastic supports to the wire harness cannot be adaptively adjusted according to the vibration frequency and amplitude. This can easily lead to excessive binding force, causing deformation or damage to the wire harness insulation layer under the restraint of the support, or insufficient binding force, making it easy for the wire harness to detach from the support when vibration occurs. Summary of the Invention

[0006] The purpose of this invention is to provide a wiring harness bracket, wiring harness fastener, and fastening method for new energy vehicles, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A wiring harness bracket for new energy vehicles, comprising:

[0009] A connecting bracket and a shock-absorbing mechanism installed on the connecting bracket. A receiving plate is connected to the shock-absorbing mechanism. A fixing plate is installed on the receiving plate in a symmetrical arrangement. A fixing plate is installed on the fixing plate.

[0010] Also includes:

[0011] An elastic restraint mechanism, mounted on a fixed plate, includes symmetrically arranged movable locking plates;

[0012] The follower component, which is mounted on the receiving plate and connected to the shock absorption mechanism, includes a movable plate. The side wall of the movable plate has symmetrically arranged inclined grooves that are connected to the elastic restraint mechanism. When the shock absorption mechanism moves, the follower component drives the movable plate to move and performs an automatic compression action on the elastic restraint mechanism through the inclined grooves to adjust the restraint force of the movable plate on the wire harness.

[0013] As a further embodiment of the present invention: the follower component includes a sliding groove formed on the receiving plate and arranged symmetrically, a sliding block is slidably installed in the sliding groove, the sliding block is connected to the movable plate, and a follower plate is provided on the side wall of the sliding block.

[0014] As a further embodiment of the present invention: the shock absorption mechanism includes a support sleeve fixed on the connecting bracket and symmetrically arranged, and a support rod connected to the receiving plate is axially slidable inside the support sleeve;

[0015] It also includes a driven component and a support component disposed on the support sleeve and connected to the follower plate, for controlling the follower plate to perform translational movements.

[0016] As a further embodiment of the present invention: the driven component includes a groove formed on the outer circumferential wall of the support sleeve, and the end of the support rod is provided with a connecting plate that is slidably connected to the groove.

[0017] As a further embodiment of the present invention: the support assembly includes a first fixing ring and a second fixing ring fixed on the support sleeve, the second fixing ring is hinged to a connecting rod that is hinged to the follower plate, the support sleeve is fitted with a first spring and a second spring, the two ends of the first spring abut against the first fixing ring and the connecting plate respectively, and the two ends of the second spring abut against the second fixing ring and the connecting plate respectively.

[0018] As a further embodiment of the present invention: the elastic restraint mechanism includes a guide post fixed on the fixed plate, the guide post having a sliding sleeve and a first push plate slidably sliding on its axial direction, the side wall of the sliding sleeve being provided with a limiting post that slides into the inclined groove, and the sliding sleeve being connected to the first push plate.

[0019] It also includes a pushing component and a guiding component disposed on the fixed plate and connected to the first push plate for adjusting the swing angle of the movable plate.

[0020] As a further embodiment of the present invention: the pushing component includes a rotating rod rotatably mounted on the fixed plate and symmetrically arranged, and the rotating rod is provided with an extension plate connected to the movable plate;

[0021] It also includes a movable sleeve and a second push plate that slide along the axial direction of the rotating rod. The movable sleeve is connected to the second push plate. A third spring is sleeved on the rotating rod, and the two ends of the third spring abut against the first push plate and the second push plate, respectively.

[0022] As a further embodiment of the present invention: the guiding component includes a spiral groove formed on the outer wall of the circumference of the rotating rod, and the inner wall of the movable sleeve is provided with a limiting block that slides and engages with the spiral groove.

[0023] A wiring harness retainer includes the aforementioned new energy vehicle wiring harness bracket.

[0024] A method for securing a wire harness includes the following steps:

[0025] Step 1: Fix the connecting bracket to the area where the wire harness needs to be restrained;

[0026] Step 2: Control the two movable plates to swing away from each other using the elastic restraint mechanism;

[0027] Step 3: Place the harness to be bound between the two movable plates;

[0028] Step 4: Under the action of the elastic restraint mechanism, the two movable clamps cross each other, and the wire harness is restrained by the fixed clamp.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: When a car vibrates while driving, the binding force on the wiring harness can be adaptively adjusted according to the vibration frequency and amplitude to ensure that the wiring harness does not detach. Specifically, under the action of the elastic binding mechanism, the movable plate binds the wiring harness. When the car vibrates while driving, the shock absorption mechanism continuously dampens the receiving plate. At the same time, when the shock absorption mechanism moves, it also drives the follower component to move, thereby driving the movable plate to move, causing the inclined groove to move. Under the action of the inclined groove and the elastic binding mechanism, the binding force of the movable plate on the wiring harness is adaptively enhanced by the elastic binding mechanism according to the damping frequency and amplitude of the damping mechanism, so as to ensure that even when the car vibrates at high frequency while driving, the problem of the wiring harness detaching from the movable plate due to vibration can be avoided.

[0030] Under the action of the first and second springs, the bearing plate is provided with good shock absorption when the vehicle vibrates during driving, avoiding the problem of loosening of the connection or damage of the connecting parts due to the rigid connection of the bearing plate during high-frequency vibration.

[0031] By cooperating with the inclined groove and the limiting post, the deformation of the third spring can be automatically adjusted according to the vibration frequency and amplitude, reducing the vibration energy transmitted to the wire harness and providing sufficient binding force to prevent the wire harness from detaching from the movable clamp due to vibration. At the same time, under the action of adaptive binding force, it can also avoid continuously providing high binding force to the wire harness, which would cause rigid friction between the wire harness and the bracket, and thus lead to conductor fatigue fracture. Under the action of buffering force, it can also avoid the problem of material fatigue of the wire harness binding components due to vibration, which would lead to damage to the binding components.

[0045] 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.

[0046] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0047] Please see Figures 1-12 In this embodiment of the invention, a wiring harness bracket for new energy vehicles includes:

[0048] A connecting bracket 1 and a shock-absorbing mechanism provided on the connecting bracket 1. A receiving plate 4 is connected to the shock-absorbing mechanism. A fixing plate 12 is provided on the receiving plate 4 in a symmetrical arrangement. A fixing plate 21 is provided on the fixing plate 12.

[0049] Also includes:

[0050] An elastic restraint mechanism is provided on the fixed plate 12, including symmetrically arranged movable locking plates 23;

[0051] The follower component, which is mounted on the receiving plate 4 and connected to the shock absorption mechanism, includes a movable plate 11. The side wall of the movable plate 11 has symmetrically arranged inclined grooves 1101 that are connected to the elastic restraint mechanism. When the shock absorption mechanism moves, the follower component drives the movable plate 11 to move, and the inclined grooves 1101 perform an automatic compression action on the elastic restraint mechanism to adjust the restraint force of the movable clamping plate 23 on the wire harness.

[0052] Specifically, in areas such as the motor or chassis of new energy vehicles, high-frequency vibrations will occur when the vehicle is in motion. To prevent the wiring harness in the motor or chassis area from detaching from the wiring harness bracket due to vibration, shock absorption is required. For this purpose, the connecting bracket 1 can be fixed to the area where the wiring harness needs to be restrained. When the wiring harness is placed between the movable clamp 23 and the fixed clamp 21, the movable clamp 23 applies a certain restraining force to the wiring harness under the action of the elastic restraint mechanism. When vibration occurs during vehicle operation, the shock absorption mechanism continuously provides shock absorption to the receiving plate 4. Simultaneously, the movement of the shock absorption mechanism also... The moving component moves, thereby driving the movable plate 11 to move, causing the inclined groove 1101 to move. Under the action of the inclined groove 1101 and the elastic restraint mechanism, according to the damping frequency and damping amplitude of the damping mechanism, the elastic restraint mechanism adaptively enhances the restraint force of the movable plate 23 on the wire harness, so as to ensure that even when the car is moving and high-frequency vibration occurs, the problem of the wire harness coming off the movable plate 23 due to vibration can be avoided. Moreover, the movable plate 23 will only enhance the restraint force on the wire harness when the car is vibrating, so as to avoid the problem of wear or deformation of the outer surface of the wire harness due to the continuous strong restraint force provided by the movable plate 23.

[0053] Please see Figures 1-5 , Figure 9 The follower component includes a symmetrically arranged groove 401 formed on the receiving plate 4, a sliding block 7 slidably installed in the groove 401, the sliding block 7 being connected to the movable plate 11, and a follower plate 8 being provided on the side wall of the sliding block 7.

[0054] Please see Figures 1-3 , Figure 5 , Figure 6The shock absorption mechanism includes a support sleeve 2 fixed to the connecting bracket 1 and symmetrically arranged, with a support rod 3 axially sliding inside the support sleeve 2 and connected to the receiving plate 4; it also includes a driven component and a support component disposed on the support sleeve 2 and connected to the follower plate 8 for controlling the follower plate 8 to perform translational movements. The driven component includes a groove 202 formed on the outer circumference of the support sleeve 2, and a connecting plate 9 slidably connected to the groove 202 at the end of the support rod 3. The support component includes a first fixing ring 201 and a second fixing ring 203 fixed to the support sleeve 2, with a connecting rod 10 hinged to the second fixing ring 203 and hinged to the follower plate 8. A first spring 5 and a second spring 6 are sleeved on the support sleeve 2, with the two ends of the first spring 5 abutting against the first fixing ring 201 and the connecting plate 9, and the two ends of the second spring 6 abutting against the second fixing ring 203 and the connecting plate 9, respectively.

[0055] In detail, in the initial state, the connecting plate 9 is located in the middle position of the slot 202, so that the distance between the connecting plate 9 and the first fixing ring 201 and the second fixing ring 203 is equal. The elongation of the first spring 5 and the second spring 6 in the natural state is greater than this distance. Therefore, the first spring 5 and the second spring 6 are both in a pre-compressed state. In this state, the thrust provided to the connecting plate 9 cancels each other out, so that the position of the connecting plate 9 on the slot 202 does not change. Under the action of the second fixing ring 203, the sliding block 7 is controlled to be located in the middle position in the slide groove 401 by the connecting rod 10 and the follower plate 8.

[0056] When the connecting bracket 1 is installed on the car and the wiring harness is bound by the movable clamp 23 and the fixed clamp 21, the car can drive normally. When the car is driving, vibration will inevitably occur, which will be transmitted to the connecting bracket 1, causing the receiving plate 4 to vibrate in the vertical direction. When the receiving plate 4 vibrates away from the support sleeve 2, it drives the support rod 3 to move, which in turn drives the connecting plate 9 to move away from the support sleeve 2. Under the action of the connecting plate 9, the second spring 6 is compressed, and at the same time, the first spring 5 is released elastically, which causes the elastic potential energy of the second spring 6 to gradually increase and the elastic release of the first spring 5 to gradually decrease.

[0057] Due to the change in the distance between the receiving plate 4 and the second fixed ring 203, the second fixed ring 203 will drive the follower plate 8 to move via the connecting rod 10, causing the sliding block 7 to slide along the length of the slide groove 401 and move towards one side of the slide groove 401, thereby driving the movable plate 11 to move. When the receiving plate 4 moves to the end of its stroke away from the support sleeve 2 due to vibration, since the elastic potential energy of the second spring 6 is greater than that of the first spring 5 at this time, the second spring 6 is released elastically and pushes the connecting plate 9 to move towards the support sleeve 2. The support rod 3 drives the receiving plate 4 to move. At this time, the elastic potential energy of the second spring 6 gradually decreases and the elastic potential energy of the first spring 5 gradually increases. When the connecting plate 9 continues to move closer to the support sleeve 2 and passes the initial position, the elastic potential energy of the second spring 6 gradually becomes less than the elastic potential energy of the first spring 5. At this time, the sliding block 7 also passes the initial position and slides towards the other side of the slide groove 401. The above steps are repeated until the vibration ends or the vibration generated by the vehicle is less than the supporting force provided to the connecting plate 9 by the first spring 5 and the second spring 6.

[0058] Preferably, when the vehicle is in motion, it is mainly subjected to vertical vibration force. The support sleeve 2 and support rod 3 are also set in the vertical direction. Under the action of the first spring 5 and the second spring 6, it can not only ensure that the bearing plate 4 has a good shock absorption effect when the vehicle is moving and vibrating, but also avoid the problem of loosening of the connection or damage of the connecting parts due to the rigid connection of the bearing plate 4 during high-frequency vibration. During vibration, it can also continuously control the radial reciprocating movement of the movable plate 11 along the slide groove 401, so as to adjust the binding force of the movable clamping plate 23 on the wire harness through the cooperation of the inclined groove 1101 and the elastic binding mechanism, ensuring that the wire harness will not detach from the movable clamping plate 23 due to vibration.

[0059] Please see Figures 1-4 , Figure 7 , Figure 8 , Figures 10-12The elastic restraint mechanism includes a guide post 13 fixed on the fixed plate 12. The guide post 13 has a sliding sleeve 15 and a first push plate 17 that slide axially. The sliding sleeve 15 has a limiting post 16 on its side wall that slides into the inclined groove 1101. The sliding sleeve 15 is connected to the first push plate 17. The mechanism also includes a pushing assembly and a guiding assembly disposed on the fixed plate 12 and connected to the first push plate 17, for adjusting the tilt angle of the movable locking plate 23. The pushing assembly includes rotating rods 14 rotatably mounted on the fixed plate 12 and symmetrically arranged. The rotating rod 14 is provided with an extension plate 22 connected to the movable card plate 23; it also includes a movable sleeve 19 and a second push plate 20 that slide along the axial direction of the rotating rod 14. The movable sleeve 19 is connected to the second push plate 20. A third spring 18 is sleeved on the rotating rod 14. The two ends of the third spring 18 abut against the first push plate 17 and the second push plate 20, respectively. The guide assembly includes a spiral groove 1401 formed on the outer circumference of the rotating rod 14. A limiting block 1901 that slides and engages with the spiral groove 1401 is provided on the inner wall of the movable sleeve 19.

[0060] Furthermore, with the guide post 13 as the central axis, the pushing component, the guiding component, the first push plate 17, the sliding sleeve 15, and the limiting post 16 are distributed in a mirror symmetrical manner. The inclined grooves 1101 are symmetrically arranged, and the two inclined grooves 1101 combine with each other on the movable plate 11 to form a V-shaped structure. Taking one of the mirror symmetrical structures as an example, in the initial state, the limiting post 16 is located at the point where the two inclined grooves 1101 are connected to each other, so that the sliding sleeve 15 is located at the end of the stroke in the direction close to the adjacent fixed plate 12, and the limiting block 1901 is located at the end of the stroke of the spiral groove 1401 on the side away from the adjacent fixed plate 12. Under the action of the sliding sleeve 15 and the movable sleeve 19, the distance between the first push plate 17 and the second push plate 20 is at its maximum state, and the elongation of the third spring 18 in its natural state is greater than this maximum distance. Therefore, the third spring 18 is in a pre-compressed state and always provides the first push plate 17 and the second push plate 20 with a thrust to move in the direction away from each other.

[0061] The movable clamping plate 23 is arranged in the shape of a claw, that is, the clamping part has a plurality of through slots that are evenly distributed. The through slots on the two movable clamping plates 23 are arranged alternately, so the two movable clamping plates 23 can cross each other to bind the wire harness. The side of the movable clamping plate 23 used for binding is also equipped with a rubber pad. Under the action of the rubber pad, it can not only play a certain buffering role, but also prevent the wire harness from being worn. The fixed clamping plate 21 is also equipped with a rubber pad on the side facing the wire harness. Under the dual action of the movable clamping plate 23 and the fixed clamping plate 21, the protection effect of the wire harness is enhanced.

[0062] When it is necessary to install and bind the wire harness, the two movable clamping plates 23 can be manually controlled to open, and the two rotating rods 14 can be controlled to rotate in opposite directions through the extension plate 22. The rotating rods 14 will drive the movable sleeve 19 to move through the spiral groove 1401 and the limiting block 1901, thereby driving the second push plate 20 to move along the length direction of the guide post 13. Under the action of the second push plate 20 and the guide post 13, the movable sleeve 19 is ensured to slide along the axial direction of the rotating rod 14 and will not rotate with the rotating rod 14. When the second push plate 20 moves, it will also compress the third spring 18. Since the limiting post 16 is located at the connection position of the two inclined grooves 1101, that is, the sliding sleeve 15 and the first push plate 17 are already located at the end of the stroke in the direction close to the adjacent fixed plate 12, the position of the first push plate 17 will not change when the third spring 18 is compressed.

[0063] When the opening angle of the two movable plates 23 reaches its maximum, the wire harness can be placed between the two movable plates 23, and the force applied to the movable plates 23 can be removed. The third spring 18 is released elastically and pushes the second push plate 20 to move toward the initial position, thereby driving the movable sleeve 19 to move. Under the action of the limiting block 1901 and the spiral groove 1401, the rotating rod 14 rotates toward the initial angle, thereby controlling the two movable plates 23 to move closer to each other and form a cross restraint to lock the position of the wire harness.

[0064] Preferably, under the action of the third spring 18, the movable clamping plate 23 can provide elastic binding force to the wire harness, avoiding rigid friction between the wire harness and the bracket caused by rigid binding, which could lead to damage to the wire harness insulation layer.

[0065] When the vehicle vibrates while driving, the first spring 5 and the second spring 6 can dampen the support plate 4. At the same time, under the influence of vibration, the wire harness tends to move towards or away from the movable clamping plate 23. When the rotating rod 14 is locked, the third spring 18 provides a thrust to the second push plate 20 and the movable sleeve 19. Under the action of the limiting block 1901 and the spiral groove 1401, the rotation of the rotating rod 14 is restricted. When the movable clamping plate 23 vibrates, it may overcome the locking force on the rotating rod 14. As a result, the two movable clamping plates 23 will deflect towards each other, reducing the binding force on the wire harness. Therefore, it is necessary to increase the elastic potential energy of the third spring 18 when vibrating, so as to enhance the binding force of the movable clamping plate 23 on the wire harness by increasing the locking force of the rotating rod 14.

[0066] In response, when vibration occurs, the movable plate 11 will continuously reciprocate along the radial direction of the slide groove 401, thereby driving the inclined groove 1101 to move. When the movable plate 11 moves towards one side of the slide groove 401, the limiting post 16 will enter one of the inclined grooves 1101 relative to the movable plate 11. Under the action of the inclined groove 1101 and the limiting post 16, the sliding sleeve 15 slides along the axial direction of the guide post 13, thereby driving the first push plate 17 to move, so that the third spring 18 is further compressed, so that the elastic potential energy of the third spring 18 increases, thereby increasing the binding force of the movable clamping plate 23 on the wire harness. When the movable plate 11 moves to the end of the stroke on one side of the slide groove 401, it will slide towards the other side of the slide groove 401. The limiting post 16 will move towards the initial position and gradually enter the other inclined groove 1101, so that the third spring 18 adaptively adjusts its own elastic potential energy according to the vibration frequency and vibration amplitude, thereby adjusting the binding force of the movable clamping plate 23 on the wire harness, ensuring that the wire harness will not detach from the movable clamping plate 23 during vibration.

[0067] Preferably, the cooperation between the inclined groove 1101 and the limiting post 16 can automatically adjust the deformation of the third spring 18 according to the vibration frequency and amplitude, reduce the vibration energy transmitted to the wire harness, and provide sufficient binding force to the wire harness to prevent the wire harness from detaching from the movable clamp 23 due to vibration. At the same time, under the action of the adaptive binding force, it can also avoid continuously providing high binding force to the wire harness, which would cause rigid friction between the wire harness and the bracket, and thus lead to conductor fatigue fracture. Under the action of the buffer force, it can also avoid the problem of material fatigue of the wire harness binding parts due to vibration, which would lead to damage to the binding parts.

[0070] Step 1: Fix the connecting bracket 1 to the area where the wire harness needs to be restrained;

[0072] Step 3: Place the wire harness to be bound between the two movable clamps 23;

[0073] Step 4: Under the action of the elastic restraint mechanism, the two movable clamps 23 cross each other, and the wire harness is restrained by the fixed clamp 21.
