Description

Technical Field

[0001] This utility model relates to the field of electric tricycle technology, and in particular to an electric vehicle motor wiring slot. Background Technology

[0002] The motor is a crucial drive component of an electric vehicle. When wiring the motor, wiring channels are needed to standardize, fix, and protect the wire connections, ensuring circuit stability and reliability and preventing short circuits or loosening. This ensures a neat and orderly wiring layout, reduces electromagnetic interference, improves insulation performance, facilitates installation, maintenance, and troubleshooting, ultimately improving motor operating efficiency, extending service life, and ensuring the overall safety and reliability of the electric vehicle.

[0003] Application No. 202222621939.2 discloses a wiring slot for an electric vehicle motor, specifically relating to the field of electric vehicles. This utility model includes a tube frame with a protective device inside. The protective device includes a wiring block with a wiring groove on its surface and placement grooves on both sides. A protective shell is fitted inside the placement grooves on the surface of the wiring block. Several partition plates are fixedly connected to the inner wall of the wiring grooves on the surface of the wiring block. Guide blocks with smooth surfaces are fixedly connected to both sides of the placement grooves on the surface of the wiring block. Protective pads are fixedly connected to both sides of the partition plates, and the size of the protective pads matches the size of the partition plates. This utility model can classify and place cables inside the wiring slot with the protective shell, preventing the cables inside the wiring slot from easily getting tangled and affecting later cable maintenance.

[0004] The above solution has shortcomings in use. When a single cable needs to be repaired, the entire protective shell must be removed. Once the protective shell is removed, the clamping and fixing of all cables will be released, causing the originally neatly arranged cables to scatter and fall out of the wiring tray. When the cables are fixed after the repair is completed, all the cables need to be sorted one by one and put back into the wiring tray in order. This not only increases the maintenance workload, but may also cause cable damage or loosening of connections during repeated disassembly and assembly, affecting the reliability of the electrical system. Therefore, we provide an electric vehicle motor wiring tray. Utility Model Content

[0005] This utility model provides a wiring slot for an electric vehicle motor. When inspecting a single cable, it is not necessary to remove the entire protective shell to inspect the cable. This keeps the cable neat and prevents it from falling out or coming off. It also reduces the possibility of physical damage to the cable and loosening of the connection caused by repeated disassembly and assembly, and enhances the long-term reliability of the electrical system.

[0006] The purpose and effect of this utility model for an electric vehicle motor wiring channel are achieved by the following specific technical means: An electric vehicle motor wiring channel includes a tube frame, and further includes:

[0007] The branch assembly is located at the bottom of the pipe rack, including a set of separately arranged junction boxes located at the bottom of the pipe rack and a connection structure on the pipe rack for installing individual junction boxes.

[0008] A fixing component used to clamp and secure one end of a cable.

[0009] Preferably, the connection structure includes a set of sleeves fitted outside each wiring frame, and the bottom end of each sleeve is connected to the inner bottom wall of the pipe rack.

[0010] Preferably, each of the wiring frames is fixedly connected to an L-shaped elastic plate on both the left and right sides, and a locking block is fixedly connected to the other end of each L-shaped elastic plate. Each L-shaped elastic plate is provided with a baffle on its exterior, and the bottom end of each baffle is connected to the inner bottom wall of the pipe rack.

[0011] Preferably, each of the card blocks is triangular, and the outer surface of the card block is in contact with the outer surface of the baffle.

[0012] Preferably, a limiting plate is fixedly connected to the front of each of the sleeve frames, and the bottom end of each limiting plate is connected to the inner bottom wall of the tube rack.

[0013] Preferably, each of the wiring frames has a heat dissipation groove on its upper surface, and the heat dissipation grooves in each group are arranged at equal distances.

[0014] Preferably, a set of arc-shaped pressure plates are fixedly connected to the inner top wall of each wiring frame.

[0015] Preferably, the fixing component includes a set of support blocks fixedly connected to the bottom wall of the tube rack, each support block has a pressure block above it, each pressure block has a connecting plate fixedly connected to its upper surface, and the other end of each connecting plate is connected to the front end of the wiring frame.

[0016] Preferably, an elastic pad is fixedly connected to the upper surface of each support block and the bottom surface of each pressure block, and each elastic pad is made of insulating material.

[0017] Preferably, a set of protective pads is fixedly connected to the inner bottom wall of the tube rack, and each of the protective pads is located inside the wiring frame.

[0018] Beneficial effects:

[0019] 1. By setting up the branching components, cables can be arranged separately and stabilized. When a single cable needs to be repaired, it will not affect the stability of the other cables, thus preventing the other cables from falling apart. This reduces the possibility of physical damage to the cables and loosening of connections caused by repeated disassembly and assembly, and enhances the long-term reliability of the electrical system.

[0020] 2. With the fixed components in place, once the wiring frame is stable, it will fix the pressure block. The pressure block and the support block will then press and fix the cable, which can effectively prevent the cable from shifting or loosening under vibration or external force, and also ensure that the cable is neatly arranged and firmly fixed.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] First Embodiment

[0031] As attached Figure 1 To be continued Figure 5 As shown: An electric vehicle motor wiring channel includes a tube frame 1, and further includes:

[0032] The branch assembly 2 is located at the bottom of the pipe rack 1. It includes a set of separately arranged wiring frames 201 located at the bottom of the pipe rack 1. When the wiring frames 201 are in the pipe rack 1, the space between the wiring frames 201 and the pipe rack 1 will form a wiring groove, which can place individual cables.

[0033] A connection structure for installing a single wiring frame 201 on the pipe rack 1 is provided. The connection structure includes a set of sleeves 202 sleeved around each wiring frame 201. The bottom end of each sleeve 202 is connected to the inner bottom wall of the pipe rack 1. L-shaped elastic plates 203 are fixedly connected to the left and right sides of each wiring frame 201. A locking block 204 is fixedly connected to the other end of each L-shaped elastic plate 203. A baffle 205 is provided on the outside of each L-shaped elastic plate 203. The bottom end of each baffle 205 is connected to the inner bottom wall of the pipe rack 1. Each locking block 204 is triangular, and the outer surface of the locking block 204 contacts the outer surface of the baffle 205. The connection structure holds the wiring frame 201 in place. 01 is fitted outside the cable placement frame. When the junction box 201 is pushed, the locking block 204 will contact the baffle 205. The baffle 205 will squeeze the locking block 204, causing the L-shaped elastic plate 203 to deform. As the junction box 201 moves, the locking block 204 will pass through the baffle 205 and be held outside the baffle 205. One end of the junction box 201 will also enter the sleeve 202, thus forming separate placement of the cables. When a single cable needs to be repaired, only the single junction box 201 needs to be removed. The remaining cables will remain in a neat state, which can prevent them from scattering or falling out, reduce the possibility of physical damage to the cables and loosening of connections caused by repeated disassembly and assembly, and enhance the long-term reliability of the electrical system.

[0034] A set of protective pads 4 are fixedly connected to the inner bottom wall of the pipe rack 1. Each protective pad 4 is located inside the wiring frame 201. The protective pads 4 can protect the cable from friction damage.

[0035] Each frame 202 has a fixed limiting plate 206 on its front side. The bottom end of each limiting plate 206 is connected to the inner bottom wall of the pipe rack 1. The limiting plate 206 can limit the position of the wiring frame 201, thereby ensuring that the wiring frame 201 is aligned with the frame 202 and facilitating its fixation. Each wiring frame 201 has a heat dissipation groove 207 on its upper surface. Each set of heat dissipation grooves 207 is arranged at equal intervals. The heat dissipation grooves 207 can dissipate heat inside the wiring frame 201, effectively reducing the operating temperature of the cable and connecting parts, reducing the aging effect of high temperature on the cable insulation layer, and extending the service life of the cable. Each wiring frame 201 has a set of arc-shaped pressure plates 208 fixedly connected to its inner top wall. The arc-shaped pressure plates 208 can stabilize the cable inside the wiring frame 201 and prevent it from shifting or loosening under vibration or external force.

[0036] Second Embodiment

[0037] As attached Figure 1 With appendix Figure 6 As shown: Fixing component 3 is used to clamp and fix one end of the cable. Fixing component 3 includes a set of support blocks 301 fixedly connected to the bottom wall of the inner wall of the pipe rack 1. Each support block 301 is provided with a pressure block 302 above it. Each pressure block 302 is fixedly connected to a connecting plate 303 on its upper surface. The other end of each connecting plate 303 is connected to the front end of the wiring frame 201. When the wiring frame 201 is stable, the wiring frame 201 will drive the pressure block 302 to move synchronously above the support block 301, thereby stabilizing the cable and further preventing the cable from shifting or loosening under vibration or external force. It can also ensure that the cable is neatly arranged and firmly fixed. Each support block 301 and each pressure block 302 is fixedly connected to an elastic pad 304. Each elastic pad 304 is made of insulating material. The elastic pad 304 can protect the cable and form a buffer protective layer between the clamping component and the cable, effectively dispersing the clamping force and avoiding mechanical damage to the cable insulation layer caused by rigid clamping.

[0038] Working principle: When in use, the cable can be placed between each set of limiting plates 206, and then the wiring frame 201 is placed between the limiting plates 206, with the cable positioned between the support block 301 and the pressure block 302. Pushing the wiring frame 201 to slide, one end of the wiring frame 201 will move towards the sleeve frame 202, and the L-shaped elastic plate 203 at the other end will push the locking block 204. The locking block 204 will contact the baffle 205, and the baffle 205 will squeeze the locking block 204, causing the L-shaped elastic plate 203 to deform. As the wiring frame 201 moves, the locking block 204 will pass through the baffle 205 and be held outside the baffle 205. One end of the wiring frame 201 will also enter the sleeve frame 202, thus forming separate placement of the cable.

[0039] When a single cable needs to be inspected, simply pinch the L-shaped elastic plate 203 of the locking block 204 to deform it, and the locking block 204 will separate from the baffle 205. Then, pull the wiring frame 201 to move it out of the sleeve 202. The remaining cables will remain in a neat state, which can prevent them from scattering or coming off, reduce the possibility of physical damage to the cables and loosening of connections caused by repeated disassembly and assembly, and enhance the long-term reliability of the electrical system.
