Description

Technical Field

[0001] This utility model relates to the field of motor bus ring technology, specifically a new energy vehicle motor bus ring assembly. Background Technology

[0002] A bus ring is an electrical connection device used in a motor. Its main function is to enable the transmission of power and signals between a fixed position and a rotating position when the motor is rotating. A bus ring typically consists of a multi-layer coaxial ring structure. Each layer of conductive rings is positioned between adjacent layers of flat wire windings within the stator slot and is electrically connected through the conductive rings to ensure stable power and signal transmission.

[0003] A search of patent application number CN202323423220.9 reveals a busbar structure for a motor stator. This utility model enhances the connection strength between the busbar assembly and the mounting frame by setting bosses and fixing feet on the support frame, and makes the connection between the busbar and the motor mounting frame more stable. In use, the copper busbars at the busbar ring are sometimes raised, which makes them convenient to use. However, the raised copper busbars may be affected by the environment or external forces, causing surface damage. Since the copper busbars are integrally injection molded with the busbar ring, they cannot be replaced if damaged, causing inconvenience in subsequent use.

[0004] Further searching patent application number CN202420569744.4 reveals that this utility model relates to the field of oil pump motors and discloses a novel manifold structure for oil pump motors. In this utility model, protective modules are fitted onto the outer and inner walls of the manifold body, effectively protecting the outer wall of the manifold body from wear and preventing internal corrosion, thereby extending the motor's service life and improving its stability and reliability in harsh environments. The design of components such as the connecting plate, through holes, sealing rings, mounting rings, and guide posts ensures the stability and balance of the mounting modules, contributing to a secure connection of the entire structure. During use, the copper busbars at the manifold are sometimes raised for ease of use; however, these raised areas may be affected by the environment or external forces, causing surface damage. Since the copper busbars are integrally injection molded with the manifold, damage cannot be replaced, leading to inconvenience in subsequent use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a new energy vehicle motor busbar assembly. The movement of the limiting plate allows the sliding rod and crossbar to move simultaneously, gradually separating them from the fixed plate. The sliding rod moves linearly along the guide rod, and the movement of the crossbar moves the positive Velcro fastener fixed to it, separating it from the negative Velcro fastener, facilitating subsequent operations. The protruding copper busbar is then rotated. Because the threaded rod is threadedly connected to the internal copper busbar, the rotating threaded rod moves upwards through the internal copper busbar, gradually moving out of the mounting hole and separating from the internal copper busbar. The protruding copper busbar can then be removed and replaced, preventing inconvenience caused by damage. This invention solves the problem that the protruding copper busbar may be damaged by environmental or external forces, as the copper busbar is integrally injection molded with the busbar, making replacement impossible if damaged, thus causing inconvenience in subsequent use.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a new energy vehicle motor bus ring assembly, including a bus ring, a moving mechanism is provided on the top of the bus ring, the number of moving mechanisms is multiple, the surface of the bus ring is provided with holes, and the interior of the bus ring is provided with an internal copper busbar.

[0007] The motion mechanism includes a raised copper busbar. The top of the inner copper busbar has a mounting hole, and a threaded rod is installed inside the mounting hole. The top of the threaded rod is fixedly connected to the raised copper busbar, and the threaded rod is threadedly connected to the inner copper busbar. Fixing plates are fixedly installed on both sides of the bottom end of the raised copper busbar. A limiting plate is installed on the top of the fixing plate, and the limiting plate has a U-shaped cross-section. The limiting plate is in contact with the fixing plate.

[0008] Preferably, a sliding rod is fixedly provided at the bottom of the end of the limiting plate away from the protruding copper busbar, and the bottom end of the sliding rod is in contact with the top of the busbar ring.

[0009] Preferably, a support rod is provided on one side of the bottom end of the sliding rod, and a guide rod is provided on one side of the fixed plate.

[0010] Preferably, the guide rod passes through the bottom end of the sliding rod and is in contact with the sliding rod, and a connecting spring is provided between the support rod and the sliding rod.

[0011] Preferably, the protruding copper busbar is in contact with the inner copper busbar, and the bottom end of the support rod is fixedly connected to the bus ring.

[0012] Preferably, a crossbar is provided on the side of the sliding rod away from the top of the support rod, and the crossbar is fixedly disposed between the two ends of the limiting plate.

[0013] Preferably, the crossbar is provided with a positive hook and loop fastener on the side near the fixing plate, and a negative hook and loop fastener is fixedly provided on the end of the fixing plate near the positive hook and loop fastener.

[0014] Preferably, the positive and negative hook and loop fasteners are bonded together, and the width and thickness of the raised copper busbar are equal to the thickness and width of the top of the inner copper busbar. Beneficial effects

[0015] This utility model provides a bus ring assembly for a new energy vehicle motor. Compared with the prior art, it has the following advantages:

[0016] 1. This new energy vehicle motor busbar assembly allows the sliding rod and crossbar to move simultaneously by moving the limiting plate, gradually separating them from the fixed plate. The sliding rod moves linearly along the guide rod, and the crossbar moves the positive Velcro fastener fixed to it, separating it from the negative Velcro fastener, facilitating subsequent operations. The raised copper busbar can then be rotated. Because the threaded rod is threadedly connected to the internal copper busbar, the rotating threaded rod moves upwards through the internal copper busbar, gradually moving out of the mounting hole and separating from the internal copper busbar. The raised copper busbar can then be removed and replaced, preventing inconvenience caused by damage.

[0017] 2. In this new energy vehicle motor busbar assembly, because the cross-sectional shape of the limiting plate is U-shaped, when the limiting plate contacts the fixing plate, the limiting plate can prevent the protruding copper busbar from rotating, and the positive and negative hook and loop fasteners can contact each other, which can improve the stability of the contact between the limiting plate and the fixing plate, reduce the automatic movement of the limiting plate, and prevent the protruding copper busbar from rotating.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-2 In accordance with 4-5, this utility model provides a technical solution: a new energy vehicle motor bus ring assembly, including a bus ring 1, a motion mechanism 2 is provided on the top of the bus ring 1, the number of motion mechanisms 2 is multiple, holes 3 are provided on the surface of the bus ring 1, and an internal copper busbar 4 is provided inside the bus ring 1.

[0027] The motion mechanism 2 includes a raised copper busbar 201. The top of the inner copper busbar 4 is provided with a mounting hole 202. A threaded rod 203 is provided inside the mounting hole 202. The top of the threaded rod 203 is fixedly connected to the raised copper busbar 201. The threaded rod 203 is threadedly connected to the inner copper busbar 4. Fixing plates 204 are fixedly provided on both sides of the bottom end of the raised copper busbar 201. A limiting plate 205 is provided on the top of the fixing plate 204. The limiting plate 205 has a U-shaped cross-section and is in contact with the fixing plate 204.

[0028] A sliding rod 206 is fixedly installed at the bottom of the end of the limiting plate 205 away from the protruding copper busbar 201. The bottom end of the sliding rod 206 contacts the top of the busbar ring 1. A support rod 207 is provided on one side of the bottom end of the sliding rod 206. A guide rod 208 is provided on one side of the fixed plate 204. The guide rod 208 passes through the bottom end of the sliding rod 206 and contacts the sliding rod 206. A connecting spring 209 is provided between the support rod 207 and the sliding rod 206, which allows the sliding rod 206 to move along the guide rod 208 in a straight line and compresses the connecting spring 209 on the outside of the guide rod 208, causing the connecting spring 209 to deform, thereby gradually bringing the sliding rod 206 closer to the support rod 207.

[0029] The raised copper busbar 201 is in contact with the inner copper busbar 4, and the bottom end of the support rod 207 is fixedly connected to the bus ring 1, so that the raised copper busbar 201 and the inner copper busbar 4 can be separated, and the raised copper busbar 201 can be removed and replaced.

[0030] Please see Figure 3 and 6 A crossbar 210 is provided on the side of the sliding rod 206 away from the top of the support rod 207, and the crossbar 210 is fixedly set between the two ends of the limiting plate 205. A positive hook and loop fastener 211 is provided on the side of the crossbar 210 near the fixed plate 204, and a negative hook and loop fastener 212 is fixedly set on the end of the fixed plate 204 near the positive hook and loop fastener 211. The positive hook and loop fastener 211 and the negative hook and loop fastener 212 are bonded together. The width and thickness of the raised copper busbar 201 are equal to the thickness and width of the top of the inner copper busbar 4. When the positive hook and loop fastener 211 and the negative hook and loop fastener 212 are in contact, the bond between the positive hook and loop fastener 211 and the negative hook and loop fastener 212 makes the connection between the limiting plate 205 and the fixed plate 204 more stable, reduces the automatic movement of the limiting plate 205, improves stability, and prevents the rotation of the raised copper busbar 201.

[0031] During operation, the entire assembly is mounted on the motor shaft. If the protruding copper busbar 201 is damaged during prolonged use, first move the limiting plates 205 on both sides of the protruding copper busbar 201, increasing the distance between the limiting plates 205 and the protruding copper busbar 201. This causes the sliding rod 206, which is fixedly connected to the limiting plates 205, to move. During this movement, the guide rod 208 passes through the bottom of the sliding rod 206 and contacts it, allowing the sliding rod 206 to move along the guide rod 208 in a straight line. This compresses the connecting spring 209 on the outside of the guide rod 208, causing the connecting spring 209 to deform, thereby gradually compressing the sliding rod 206. Approaching the support rod 207, when the limiting plate 205 moves, it drives the crossbar 210 to move, and the positive Velcro 211 fixedly connected to the crossbar 210 moves, separating from the negative Velcro 212, ensuring the movement of the limiting plate 205. Through the continuous movement of the limiting plate 205, it can be separated from the fixing plate 204, facilitating subsequent operations. After separation, the protruding copper busbar 201 is rotated, which drives the threaded rod 203 at the bottom to rotate. Since the threaded rod 203 is threadedly connected to the internal copper busbar 4, the internal copper busbar 4 allows the rotating threaded rod 203 to move upward, gradually moving it out of the mounting hole 202, separating it from the internal copper busbar 4. The protruding copper busbar 201 can then be removed and replaced to prevent inconvenience caused by damage.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
