Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that when the wiring harness of a new energy vehicle is hooked by a worker or a maintenance and installation tool held by the worker and bears a large tensile force, it is unable to buffer the tensile force, and it is easy to cause damage or breakage of the wiring harness, and to propose a pressing device and method for processing internal wiring harnesses of new energy vehicles.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: A pressing device for processing internal wiring harnesses of new energy vehicles includes a bottom plate, and a bracket is fixedly installed on the upper end of the bottom plate; A pressing mechanism for pressing the internal wiring harnesses of new energy vehicles is further provided. The pressing mechanism includes a slider slidably installed through the middle of the bracket. A first spring is fixedly installed at the rear end of the slider, and the rear end of the first spring is fixedly installed on the bracket. A fixed seat is fixedly installed on the lower side of the slider, and the lower end of the fixed seat is slidably installed on the bottom plate.

The fixing mechanism includes a fixed clamping plate abutted and attached to the lower end of the bottom plate, and a guide rod is fixedly installed at the lower end of the fixed clamping plate.

[0007] Preferably, a telescopic rod is fixed in the middle of the upper end of the limit pressing plate. A second spring is sleeved on the outer side of the telescopic rod. The upper and lower ends of the second spring are respectively fixedly connected to the telescopic rod and the limit pressing plate. The upper end of the telescopic rod is rotatably installed with a first screw rod. The upper end of the first screw rod is threadedly installed on the fixed seat.

[0008] Preferably, elastic side clamping strips are provided on both the left and right sides of the limit pressing plate. Through grooves are correspondingly formed in the left and right ends of the limit pressing plate for the elastic side clamping strips. The front ends of the elastic side clamping strips are slidably installed through the fixed seat.

[0009] Preferably, a second screw rod is threadedly installed on the right elastic side clamping strip. The left end of the second screw rod is rotatably installed on the fixed seat. Rack teeth are fixedly installed at the front ends of the elastic side clamping strips. A gear is meshed between the rack teeth. The gear is rotatably installed on the fixed seat.

[0010] Preferably, a top strip is fixedly installed in the middle of the upper end of the limit pressing plate. An inclined block plate is fixedly installed at the lower end of the bracket corresponding to the top strip.

[0011] Preferably, a connecting plate is slidably installed in the middle of the rear side of the fixed seat. The lower end of the connecting plate is slidably installed on the bottom plate. A T-shaped sliding groove is formed in the fixed seat corresponding to the connecting plate. A slope is formed in the T-shaped groove of the connecting plate corresponding to the fixed seat.

[0012] Preferably, a winding barrel is fixedly installed at the rear side of the upper end of the connecting plate. A cross plate is fixedly installed in the middle of the winding barrel. A limit strip is abutted and attached to the rear end of the cross plate.

[0013] Preferably, a connecting rod is fixedly installed at the rear end of the limit strip. The rear end of the connecting rod penetrates and is slidably installed with a movable plate. The movable plate is slidably installed on the cross plate. A third spring is sleeved on the outer side of the connecting rod.

[0014] Preferably, the lower end of the guide rod penetrates and is slidably installed with a connecting frame. A fourth spring is sleeved on the outer side of the guide rod. The upper end of the connecting frame is fixedly connected to the bottom plate.

[0015] A method for using a pressing device for processing internal wiring harnesses of new energy vehicles is as follows: Step 1: Fix the device on the frame of the new energy vehicle through the fixing mechanism; Step 2: Fix the end of the wiring harness of the new energy vehicle through the fixed seat and the limit pressing plate; Step 3: Then drive the elastic side clamping strips on both sides to limit the excess extended wiring harnesses on both sides of the wiring harness end by rotating the second screw rod; Step 4: Wind and fix the excess length of the wiring harness through the provided winding barrel; Step 5: Buffer the external pulling force on the wiring harness through the provided first spring, and when the external pulling force on the wiring harness is too large, disconnect the wiring harness from the device through the provided top strip and inclined block plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, first, the device is fixed to the frame of the new energy vehicle to be fixed through the fixed clamping plate and the bottom plate. Then, the inclined surface on the fixed clamping plate is aligned with the frame of the new energy vehicle. By pushing the device, the inclined surface on the fixed clamping plate will slide on the frame, thereby driving the guide rod to slide on the connecting frame and compressing the fourth spring until the frame stops when it moves between the fixed clamping plate and the bottom plate. This makes it convenient to fix the device on the frame of the new energy vehicle. The operation is simple, fast, and can be operated with one hand, improving work efficiency.

[0017] 2. In the present invention, the end of the internal wiring harness of the new energy vehicle is placed inside the fixed seat and below the limiting pressure plate. Rotating the first screw drives the telescopic rod and the limiting pressure plate to slide downward on the fixed seat. When the lower end of the limiting pressure plate contacts the end of the wiring harness inside the fixed seat, continuing to rotate the first screw forces the telescopic rod to automatically contract and the second spring to be compressed, which is beneficial to fixing the end of the wiring harness inside the fixed seat, enabling the wiring harness to be straightened and avoiding the situation where the wiring harness spreads out and droops, affecting the normal maintenance and installation of the new energy vehicle by the staff.

[0018] 3. In the present invention, rotating the second screw drives the elastic side clip on the right side and the rack fixed thereto to move leftward, driving the gear to rotate. The gear drives the elastic side clip on the other side and the rack fixed thereto to move rightward, making the elastic side clips on both sides move relatively and abutting and fitting on the wiring harnesses on both sides of the end of the wiring harness. The elastic side clips provided on both sides are convenient for limiting the wiring harnesses on both sides of the end of the wiring harness, reducing the state where multiple wiring harnesses at the end spread outwards, and thus being beneficial to improving the compression degree of the wiring harness.

[0019] 4. In the present invention, the provided winding barrel is convenient for first winding the longer wiring harness on the winding barrel and then fixing it, thereby improving the applicable range of wiring harness compression. After the winding and fixing are completed, pushing the movable plate downward drives the connecting rod and the limiting strip to slide downward. When the limiting strip separates from the movable plate, the limiting strip and the connecting rod extend towards the winding barrel under the action of the third spring, and the limiting strip tightly abuts against the wiring harness wound on the outer side of the winding barrel, effectively preventing the wiring harness wound on the outer side of the winding barrel from spreading outwards.

[0020] 5. In the present invention, when the compressed wiring harness is accidentally caught by the staff or the tools they carry, the wiring harness will drive the fixed seat, the limiting pressure plate, and the slider to slide outward on the bottom plate synchronously, compressing the first spring. The first spring provided is convenient for buffering when the wiring harness is subjected to an external pulling force, reducing the situation where the wiring harness is damaged by being strained when directly fixed and then subjected to an external pulling force, and thus being convenient for protecting the wiring harness.

[0021] 6. In the present invention, when the pulling force is too large, it will drive the fixed seat, the connecting plate, and the winding barrel to continue sliding outwards. When the connecting plate detaches from the bottom plate, under the action of the slope, it will continue to slide and separate from the fixed seat, so that the connecting plate and the winding barrel will remain suspended. With the continuous pulling force of the wire harness, it will drive the fixed seat, the limiting pressing plate, and the top bar to continue moving outwards. When the top bar contacts the inclined block plate, it will slide on the inclined surface of the inclined block plate, and then will push the top bar and the limiting pressing plate to slide upwards on the fixed seat. At this time, the telescopic rod and the second spring will be further contracted and compressed adaptively. Since when the limiting pressing plate slides upwards, the clamping force on the end of the wire harness will be lost, and then it will detach from between the limiting pressing plate and the fixed seat, causing the wire harness to separate from the device (the end of the wire harness will also directly squeeze the elastic side clamping strip, causing it to deform, and then it will also break away from the restriction of the two elastic side clamping strips). In this way, it can be avoided that when the wire harness is subjected to too large an external pulling force, it cannot be separated from the pressing device in time, resulting in the situation of being strained or even broken, effectively protecting the integrity of the wire harness and preventing it from being strained and damaged.

The pressing mechanism includes a slider 3 slidably installed through the middle of the bracket 2. A first spring 4 is fixedly installed at the rear end of the slider 3, and the rear end of the first spring 4 is fixedly installed on the bracket 2. A fixed seat 5 is fixedly installed on the lower side of the slider 3, and the lower end of the fixed seat 5 is slidably installed on the bottom plate 1. A limiting pressing plate 6 is slidably installed through the middle of the fixed seat 5. A telescopic rod 7 is fixedly installed in the middle of the upper end of the limiting pressing plate 6. A second spring 8 is sleeved on the outer side of the telescopic rod 7, and the upper and lower ends of the second spring 8 are respectively fixedly connected to the telescopic rod 7 and the limiting pressing plate 6. A first screw 9 is rotatably installed at the upper end of the telescopic rod 7, and the upper end of the first screw 9 is threadedly installed on the fixed seat 5. Elastic side clamping strips 10 are provided on both the left and right sides of the limiting pressing plate 6. Through grooves 11 are respectively opened on the left and right ends of the limiting pressing plate 6 corresponding to the elastic side clamping strips 10. The front ends of the elastic side clamping strips 10 are slidably installed through the fixed seat 5. A second screw 12 is threadedly installed on the right elastic side clamping strip 10, and the left end of the second screw 12 is rotatably installed on the fixed seat 5. Rack bars 13 are fixedly installed at the front ends of the elastic side clamping strips 10, and a gear 14 is meshed between the rack bars 13. The gear 14 is rotatably installed on the fixed seat 5. A top bar 15 is fixedly installed in the middle of the upper end of the limiting pressing plate 6, and an inclined block plate 16 is fixedly installed at the lower end of the bracket 2 corresponding to the top bar 15. A connecting plate 17 is slidably installed in the middle of the rear side of the fixed seat 5, and the lower end of the connecting plate 17 is slidably installed on the bottom plate 1. A T-shaped chute is opened on the fixed seat 5 corresponding to the connecting plate 17, and a slope 171 is opened on the T-shaped groove of the connecting plate 17 corresponding to the fixed seat 5. A winding barrel 18 is fixedly installed at the rear side of the upper end of the connecting plate 17. A cross plate 19 is fixedly installed in the middle of the winding barrel 18. A limiting strip 22 is abutted and fitted at the rear end of the cross plate 19. A connecting rod 23 is fixedly installed at the rear end of the limiting strip 22. The rear end of the connecting rod 23 is slidably installed through a movable plate 24. The movable plate 24 is slidably installed on the cross plate 19, and a third spring 25 is sleeved on the outer side of the connecting rod 23; During operation, place the end of the internal wiring harness of a new energy vehicle inside the fixed seat 5 and below the limit pressure plate 6. Rotate the first screw 9 to drive the telescopic rod 7 and the limit pressure plate 6 to slide downward on the fixed seat 5. When the lower end of the limit pressure plate 6 contacts the end of the wiring harness inside the fixed seat 5, continue to rotate the first screw 9, forcing the telescopic rod 7 to automatically contract and the second spring 8 to be compressed. This is beneficial for fixing the end of the wiring harness inside the fixed seat 5, enabling the wiring harness to be straightened, avoiding the situation where the wiring harness spreads out and droops, which affects the normal maintenance and installation of the new energy vehicle by workers. Rotate the second screw 12 to drive the elastic side clip 10 on the right and the rack 13 fixed to it to move leftward, driving the gear 14 to rotate. The gear 14 drives the elastic side clip 10 on the other side and the rack 13 fixed to it to move rightward, making the elastic side clips 10 on both sides move relatively, and making the elastic side clips 10 on both sides abut and fit on the wiring harness on both sides of the end of the wiring harness. The elastic side clips 10 on both sides are provided to facilitate limiting the wiring harness on both sides of the end of the wiring harness, reducing the state where multiple wiring harnesses at the end spread outwards, which is beneficial for improving the compression degree of the wiring harness. The winding barrel 18 is provided to facilitate winding the longer wiring harness on the winding barrel 18 first and then fixing it, which can improve the applicable range of wiring harness compression. After winding and fixing are completed, push the movable plate 24 downward to drive the connecting rod 23 and the limit bar 22 to slide downward. When the limit bar 22 separates from the movable plate 24, the limit bar 22 and the connecting rod 23 extend towards the winding barrel 18 under the action of the third spring 25, making the limit bar 22 closely abut on the wiring harness wound outside the winding barrel 18, effectively preventing the wiring harness wound outside the winding barrel 18 from spreading outwards. When the compressed wiring harness is accidentally caught by a worker or the tools they carry, the wiring harness will drive the fixed seat 5, the limit pressure plate 6, and the slider 3 to slide outward on the bottom plate 1, compressing the first spring 4. The first spring 4 is provided to facilitate buffering when the wiring harness is subjected to an external tensile force, reducing the situation where the wiring harness is damaged by being pulled when it is directly fixed and then subjected to an external tensile force, which is beneficial for protecting the wiring harness. When the tensile force is too large, it will drive the fixed seat 5, the connecting plate 17, and the winding barrel 18 to continue sliding outward. When the connecting plate 17 separates from the bottom plate 1, it will continue to slide and separate from the fixed seat 5 under the action of the slope 171. Thus, the connecting plate 17 and the winding barrel 18 will remain suspended. As the wiring harness continues to be pulled, it will drive the fixed seat 5, the limit pressure plate 6, and the top bar 15 to continue moving outward. When the top bar 15 contacts the inclined block plate 16, it will slide on the inclined surface of the inclined block plate 16, and then push the top bar 15 and the limit pressure plate 6 to slide upward on the fixed seat 5. At this time, the telescopic rod 7 and the second spring 8 will be further contracted and compressed adaptively. Since the limit pressure plate 6 slides upward, the clamping force on the end of the wiring harness will be lost, and then it will break away from between the limit pressure plate 6 and the fixed seat 5, separating the wiring harness from the device (the end of the wiring harness will also directly squeeze the elastic side clip 10, causing it to deform,Furthermore, it will also break away from the restrictions of the two elastic side clamping strips 10), which can avoid the situation that when the wire harness is subjected to excessive external tensile force and cannot be separated from the pressing device in time, resulting in strain or even breakage, effectively protecting the integrity of the wire harness and preventing it from being strained and damaged.

[0026] As an embodiment of the present invention, a fixing mechanism for fixing the bottom plate 1 on the frame of a new energy vehicle is further provided. The fixing mechanism includes a fixing clamp plate 26 that is abutted and fitted to the lower end of the bottom plate 1. A guide rod 27 is fixedly installed at the lower end of the fixing clamp plate 26. The lower end of the guide rod 27 is slidably installed through a connecting frame 28. A fourth spring 29 is sleeved on the outer side of the guide rod 27. The upper end of the connecting frame 28 is fixedly connected to the bottom plate 1. During operation, the device is aligned with the frame of the new energy vehicle to be fixed through the fixing clamp plate 26 and the bottom plate 1. Then, by aligning the inclined surface on the fixing clamp plate 26 with the frame of the new energy vehicle and pushing the device, the inclined surface on the fixing clamp plate 26 will slide on the frame, thereby driving the guide rod 27 to slide on the connecting frame 28 and compressing the fourth spring 29 until the frame moves between the fixing clamp plate 26 and the bottom plate 1 and stops. This facilitates fixing the device on the frame of the new energy vehicle. The operation is simple, fast, and convenient, and can be operated with one hand, improving work efficiency.

[0027] A method for using a pressing device for processing wire harnesses inside a new energy vehicle is as follows: Step 1: Fix the device on the frame of the new energy vehicle through the fixing mechanism; Step 2: Fix the end of the wire harness of the new energy vehicle through the fixing seat 5 and the limiting pressing plate 6; Step 3: Then, drive the two elastic side clamping strips 10 to limit the excess protruding wire harnesses on both sides of the wire harness end by rotating the second screw 12; Step 4: Wind and fix the wire harness of the excess length through the provided winding barrel 18; Step 5: Buffer the external tensile force received by the wire harness through the provided first spring 4, and when the wire harness receives excessive external tensile force, disconnect from the device through the provided top strip 15 and inclined block plate 16.

[0028] Working principle: When the present invention is in use, first, the device is aligned with the frame of the new energy vehicle to be fixed through the fixed clamping plate 26 and the bottom plate 1. Then, the inclined surface on the fixed clamping plate 26 is aligned with the frame of the new energy vehicle, and the device is pushed. The inclined surface on the fixed clamping plate 26 will slide on the frame, thereby driving the guide rod 27 to slide on the connecting frame 28 and compressing the fourth spring 29 until the frame stops when it moves between the fixed clamping plate 26 and the bottom plate 1. This facilitates fixing the device on the frame of the new energy vehicle. The operation is simple, fast, and convenient, and can be operated with one hand, improving work efficiency. Then, the end of the wire harness inside the new energy vehicle is placed in the fixed seat 5 and is located below the limit pressing plate 6. Rotate the first screw rod 9 to drive the telescopic rod 7 and the limit pressing plate 6 to slide downward on the fixed seat 5. When the lower end of the limit pressing plate 6 contacts the end of the wire harness in the fixed seat 5, continue to rotate the first screw rod 9, forcing the telescopic rod 7 to automatically contract and the second spring 8 to be compressed, which is conducive to fixing the end of the wire harness in the fixed seat 5, enabling the wire harness to be straightened, avoiding the wire harness from spreading and drooping, and affecting the normal maintenance and installation of the new energy vehicle by the staff. Rotate the second screw rod 12 to drive the elastic side clip 10 on the right side and the rack 13 fixed thereto to move leftward, driving the gear 14 to rotate. The gear 14 drives the elastic side clip 10 on the other side and the rack 13 fixed thereto to move rightward, making the elastic side clips 10 on both sides move relatively, and the elastic side clips 10 on both sides abut and fit on the wire harnesses on both sides of the end of the wire harness. The elastic side clips 10 on both sides are provided to facilitate limiting the wire harnesses on both sides of the end of the wire harness, reducing the state of multiple wire harnesses spreading outward at the end, which is conducive to improving the pressing degree of the wire harness. The provided winding barrel 18 facilitates winding the longer wire harness on the winding barrel 18 first and then fixing it, thereby increasing the applicable range of wire harness pressing. After winding and fixing are completed, push the movable plate 24 downward to drive the connecting rod 23 and the limit strip 22 to slide downward. When the limit strip 22 separates from the movable plate 24, the limit strip 22 and the connecting rod 23 extend toward the winding barrel 18 under the action of the third spring 25, making the limit strip 22 tightly abut against the wire harness wound outside the winding barrel 18, effectively preventing the wire harness wound outside the winding barrel 18 from spreading outward. When the pressed wire harness is accidentally caught by the staff or the tools they carry, the wire harness will drive the fixed seat 5, the limit pressing plate 6, and the slider 3 to slide outward on the bottom plate 1, compressing the first spring 4. The provided first spring 4 facilitates buffering when the wire harness is subjected to an external tensile force, reducing the situation where the wire harness is damaged by being strained when directly fixed and then subjected to an external tensile force, thereby facilitating protecting the wire harness. When the tensile force is too large, it will drive the fixed seat 5, the connecting plate 17, and the winding barrel 18 to continue sliding outward. When the connecting plate 17 detaches from the bottom plate 1, it will continue to slide and separate from the fixed seat 5 under the action of the slope 171. Thus, the connecting plate 17 and the winding barrel 18 will remain suspended. As the wire harness continues to be pulled,It will drive the fixed seat 5, the limit pressing plate 6 and the top bar 15 to continue moving outwards. When the top bar 15 contacts the inclined block plate 16, it will slide on the inclined surface of the inclined block plate 16, and then push the top bar 15 and the limit pressing plate 6 to slide upwards on the fixed seat 5. At this time, the telescopic rod 7 and the second spring 8 will be further contracted and compressed adaptively. Since the limit pressing plate 6 slides upwards, the clamping force on the end of the wire harness will be lost, and then it will break away from between the limit pressing plate 6 and the fixed seat 5, separating the wire harness from the device (the end of the wire harness will also directly squeeze the elastic side clamping strip 10, causing it to deform, and then it will also break away from the restriction of the two elastic side clamping strips 10). In this way, it can be avoided that when the external pulling force on the wire harness is too large, it cannot be separated from the pressing device in time, resulting in the situation of being strained or even broken, effectively protecting the integrity of the wire harness and preventing it from being strained and damaged.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
