Description

Technical Field

[0001] This utility model relates to the field of electric vehicle batteries, and in particular to a battery for electric vehicles. Background Technology

[0002] Lead-acid batteries, as a common type of rechargeable battery, are widely used in the electric vehicle industry due to their advantages such as stable electromotive force during discharge and stable operating voltage. In practical applications, multiple lead-acid batteries are often connected in series. However, during the series connection process, users need to spend considerable time fixing the connecting cables to the battery terminals, which not only increases the difficulty of the connection operation but also reduces its efficiency.

[0003] A search revealed that the patent CN218334212U, "High-efficiency lead-acid battery for electric vehicles," provides a solution to the aforementioned problem. The battery in this patent includes multiple independently working battery components, each equipped with a negative terminal and a positive terminal, with the negative terminal located on the side of the positive terminal. The negative and positive terminals also have protruding teeth on their outer sides and are equipped with connecting rings that fit on these two terminals. This design eliminates the need for users to spend time fixing connecting cables, thus reducing the difficulty of connecting lead-acid batteries in series to a certain extent.

[0004] However, this installation method, which relies on the engagement of the protruding teeth with the grooves on the connecting ring, has certain limitations. After repeated disassembly and installation, the engagement is prone to loosening. Moreover, during vehicle operation, due to bumps and vibrations, the engagement may also loosen, affecting the normal use of the lead-acid battery. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a storage battery for electric vehicles.

[0006] The present invention provides a storage battery for electric vehicles, which adopts the following technical solution:

[0007] An electric vehicle battery includes several battery packs, each battery having two sets of positive and negative terminals. It also includes a connecting sleeve, a docking assembly, a conductive head, and wires. The connecting sleeve is fixed to the outside of the positive and negative terminals on the battery. Both ends of the wires are connected to the docking assembly. The conductive head is connected to the wire core inside the wire and is fixed to the bottom of the docking assembly. The docking assembly and the connecting sleeve quickly engage. When the docking assembly and the connecting sleeve are fixed together, the conductive head abuts against the positive and negative terminals.

[0008] Optionally, the outer wall of the connecting sleeve is provided with an L-shaped groove, and the top of the connecting sleeve is provided with an annular groove, and a plurality of ratchet teeth arranged in an annular array along the axis of the connecting sleeve are provided in the annular groove.

[0009] The docking assembly includes a fixing plate, the outer diameter of which is equal to the inner diameter of the connecting sleeve;

[0010] A connecting block, wherein the connecting block is disposed on a fixed disk;

[0011] A limiting plate is provided on a connecting block. A limiting ring is connected to the bottom of the limiting plate. A limiting block is provided at the bottom of the inner side wall of the limiting ring. The limiting block can move freely in the L-shaped groove.

[0012] A limiting component is disposed on a fixed disk, and the limiting component and the ratchet form a ratchet mechanism;

[0013] The conductive head passes through the fixed plate, the connecting block and the limiting plate and connects to the wire core inside the conductor.

[0014] Optionally, the limiting assembly includes an insert block, a slide groove, a spring, a push plate, and a lever. The slide groove is disposed on a fixed block, and the insert block slides within the slide groove. The push plate is disposed at the end of the insert block. One end of the spring is connected to the push plate, and the other end is fixed to the connecting block. A through groove is provided on the limiting plate, and the lever is fixed to the insert block and extends through the through groove.

[0015] Optionally, the end of the insert is provided with an inclined surface adapted to the ratchet, and the inclination angle of the inclined surface is the same as the inclination angle of the ratchet tooth surface.

[0016] Optionally, at least three T-slots and limiting blocks are provided.

[0017] Optionally, the top of the limiting plate is provided with a rotating handle, and the outer wall of the rotating handle is covered with an anti-slip rubber sleeve, the surface of which is provided with a number of anti-slip patterns distributed along the axial direction.

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] 1. When it is necessary to fix the docking components and the connecting sleeves relative to each other, simply insert the connecting block into the connecting sleeve. Make sure that the limiting block on the limiting ring is aligned with the L-shaped groove on the outer wall of the connecting sleeve. When the limiting block is fully inserted, the bottom of the limiting plate is exactly against the top of the connecting sleeve, and the bottom of the conductive head is against the positive and negative poles inside the connecting sleeve. Rotate the limiting plate, and the ratchet mechanism formed by the limiting component and the ratchet tooth allows unidirectional rotation. At this time, the limiting block moves completely from one end of the L-shaped groove to the other end, forming an axial lock between the limiting plate and the connecting sleeve. This method greatly improves the efficiency of wire bundling.

[0020] 2. When disassembly is required, simply move the lever to compress the spring in the slide block and slide it into the slide block. The end of the insert will then disengage from the ratchet teeth. At this time, the one-way locking state of the ratchet mechanism formed by the limiting component and the ratchet teeth is released. Rotate the limiting plate in the opposite direction, and the limiting block can move smoothly from the other end of the L-shaped groove back to the initial end. The axial locking between the limiting plate and the connecting sleeve will then fail. Subsequently, pull the connecting block out of the connecting sleeve to complete the separation of the docking component and the connecting sleeve, realizing the quick disassembly of the wire. This detachable structure ensures the stability of the connection while effectively avoiding the loosening problem caused by repeated disassembly and assembly, further improving the convenience and reliability of the battery during use.

[0021] 3. At least three T-slots are provided on the outside of the connecting sleeve and at least three limit blocks are provided on the inner wall of the limit ring. The multiple T-slots and limit blocks are evenly distributed, which can distribute the force between the docking component and the connecting sleeve to multiple contact points. During the bumpy and vibrating process of vehicle driving, the force on the overall structure is more even, which further enhances the stability and durability of the connection.

[0031] Furthermore, "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] This utility model discloses a storage battery for electric vehicles. (Refer to...) Figure 1-2 An electric vehicle battery includes several battery packs, a connecting sleeve, a docking assembly, a conductive head, and wires. The battery has two sets of positive and negative terminals. The connecting sleeve is fixed to the outside of the positive and negative terminals on the battery. Both ends of the wires are connected to the docking assembly. The conductive head is connected to the wire core inside the wire and is fixed to the bottom of the docking assembly. The docking assembly and the connecting sleeve are quickly snapped together. When the docking assembly and the connecting sleeve are fixed together, the conductive head abuts against the positive and negative terminals.

[0033] Specifically, refer to Figure 2 The outer wall of the connecting sleeve is provided with an L-shaped groove, and the top of the connecting sleeve is provided with an annular groove, and several ratchet teeth arranged in an annular array along the axis of the connecting sleeve are provided in the annular groove.

[0034] The docking assembly includes a fixed plate, a connecting block, a limiting plate, and a limiting component. The outer diameter of the fixed plate is equal to the inner diameter of the connecting sleeve. The connecting block is set on the fixed plate, and the limiting plate is set on the connecting block. A limiting ring is connected to the bottom of the limiting plate, and a limiting block is set at the bottom of the inner side wall of the limiting ring. The limiting block can move freely in the L-shaped groove. The limiting component is set at the bottom of the fixed plate. The limiting component and the ratchet form a ratchet mechanism. When it is necessary to fix the docking assembly and the connecting sleeve relative to each other, simply insert the connecting block into the connecting sleeve. Note that the limiting block on the limiting ring should be aligned with the L-shaped groove on the outer wall of the connecting sleeve. When the limiting block is fully inserted, the bottom of the limiting plate is exactly against the top of the connecting sleeve, and the bottom of the conductive head is against the positive and negative poles inside the connecting sleeve. Rotating the limiting plate allows unidirectional rotation of the ratchet mechanism formed by the limiting component and the ratchet. At this time, the limiting block moves completely from one end of the L-shaped groove to the other end, forming an axial lock between the limiting plate and the connecting sleeve. This method greatly improves the efficiency of wire bundling.

[0035] Reference Figure 3-6 The limiting assembly includes an insert block, a slide groove, a spring, a push plate, and a lever. The slide groove is mounted on a fixed block, and the insert block slides within the slide groove. The end of the insert block has an inclined surface adapted to a ratchet tooth, with the inclination angle of the inclined surface being the same as the inclination angle of the ratchet tooth surface. The push plate is located at the other end of the insert block. One end of the spring is connected to the push plate, and the other end is fixed to a connecting block. A through groove is provided on the limiting plate, and a lever is fixed to the insert block, passing through the through groove. When disassembly is required, simply move the lever to compress the spring within the slide groove and slide the insert block further into the slide groove. It will then disengage from between the ratchet teeth. At this point, the one-way locking state of the ratchet mechanism formed by the limiting component and the ratchet teeth is released. By rotating the limiting plate in the opposite direction, the limiting block can smoothly move back to the initial end from the other end of the L-shaped groove, and the axial locking between the limiting plate and the connecting sleeve will become ineffective. Subsequently, the connecting block can be pulled out from the connecting sleeve to complete the separation of the docking component and the connecting sleeve, realizing the quick disassembly of the wire. This detachable structure ensures the stability of the connection while effectively avoiding the loosening problem caused by repeated disassembly and assembly, further improving the convenience and reliability of the battery during use.

[0036] At least three T-slots are provided on the outside of the connecting sleeve and at least three limit blocks are provided on the inner wall of the limit ring. The multiple T-slots and limit blocks are evenly distributed, which can distribute the force between the docking component and the connecting sleeve to multiple contact points. During the bumpy and vibrating process of vehicle driving, the force on the overall structure is more even, which further enhances the stability and durability of the connection.

[0037] The top of the limiting plate is equipped with a rotating handle, and the outer wall of the rotating handle is covered with an anti-slip rubber sleeve. The surface of the anti-slip rubber sleeve is provided with several anti-slip patterns distributed along the axial direction.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
