Description

Technical Field

[0001] The present invention relates to the field of battery technology, and in particular to an all-in-one plug-in anti-rotation bracket and a battery pack. Background Art

[0002] The automotive industry is currently undergoing revolutionary changes, with electric vehicles gradually replacing traditional fuel-powered vehicles. As a core component of new energy vehicles, the performance of the power battery pack directly affects vehicle performance.

[0003] Typically, in a power battery pack, current is output from the plug-in unit, forming a circuit diagram that connects the copper / aluminum busbars within the pack to the plug-in unit, and finally to the vehicle's high-voltage wiring harness. As the intermediate electrical connection point, the plug-in unit is particularly important for protection.

[0004] When securing the copper / aluminum busbars and the electrical connections between the plug-in modules within the battery pack, the busbars can rotate when the bolts are tightened, causing misalignment and installation difficulties. Therefore, an anti-rotation bracket is necessary. However, 2-pin plug-ins are commonly used within battery packs, and the corresponding anti-rotation brackets are not compatible with 3-pin plug-ins, making them less versatile. Summary of the Invention

In this way, the pins of the plug-in and the conductive bar can be bolted and installed on the mounting platform. The rotation-stop groove can cooperate with the conductive bar to limit the conductive bar. When the pins of the plug-in and the conductive bar are connected by bolts, the conductive bar is limited to prevent rotation of the conductive bar, thereby improving the assembly convenience and stability of the plug-in and the conductive bar. Since a plurality of mounting platforms are staggered, they can adapt to the connection of a plug-in with multiple pins and multiple conductive bars, and have strong versatility.

[0008] In an optional embodiment, the mounting platform is provided with a plurality of anti-rotation grooves, and the openings of the plurality of anti-rotation grooves face different directions.

[0010] In an optional embodiment, each mounting platform is provided with at least two third limiting plates, and a rotation-stop groove is formed between adjacent third limiting plates, and the top of the third limiting plate is higher than the top of the first limiting plate.

[0011] In an optional embodiment, a cover body is further included, which includes a plurality of cover plates adapted to the mounting platform of the base and a connecting plate connecting adjacent cover plates, and the cover body is detachably connected to the base.

[0014] In an optional embodiment, the cover is divided into a plurality of parts, and the parts are detachably connected to the base and / or adjacent parts are detachably connected via a snap-fit ​​structure.

[0015] In an optional embodiment, the pins of the plug-in and the conductive bar are fastened together by locking bolts, and the mounting platform is provided with grooves for avoiding the locking bolts; and / or, each cover plate is provided with a bulge for avoiding the locking bolts.

[0016] In the second aspect, the present invention also provides a battery pack, including a plug-in, a conductive bar and the multi-in-one plug-in anti-rotation bracket in the above technical solution. The plug-in is provided with multiple pins, and the ends of the pins and the ends of the conductive bar are provided with mounting holes.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0032] The following combination Figures 1 to 10 , describing embodiments of the present invention.

[0033] According to an embodiment of the present invention, in a first aspect, an all-in-one plug-in anti-rotation bracket 1 is provided, comprising a base 11, the base 11 comprising a plurality of staggered mounting platforms 111, each mounting platform 111 being provided with a rotation-stop groove 112 adapted to the conductive bar 3, the base 11 also comprising a plurality of plug-in interfaces 113 adapted to the pins 21 of the plug-in 2, each plug-in interface 113 passing through the base 11 to the corresponding mounting platform 111.

[0034] The multi-in-one plug-in anti-rotation bracket 1 provided in an embodiment of the present invention has a base 11 including a plurality of staggered mounting platforms 111, each of which is provided with a rotation-stop groove 112. A plug-in interface 113 adapted to the pins 21 of the plug-in 2 extends to the mounting platform 111, so that the pins 21 of the plug-in 2 and the conductive bar 3 can be bolted and installed on the mounting platform 111. The rotation-stop groove 112 can cooperate with the conductive bar 3 to limit the conductive bar 3. When the pins 21 of the plug-in 2 and the conductive bar 3 are connected by bolts, the conductive bar 3 is limited in position and prevented from rotating, thereby improving the assembly convenience and stability of the plug-in 2 and the conductive bar 3. Since multiple mounting platforms 111 are staggered, they can adapt to the connection between a plug-in 2 with multiple pins 21 and multiple conductive bars 3, and have strong versatility. For example, when three mounting platforms 111 are provided, a 3-pin high-voltage connector can be adapted. The number and position of the mounting platform 111 can be adjusted according to the different PIN numbers of the plug-in 2, and the structure of the all-in-one plug-in anti-rotation bracket 1 can be adjusted accordingly to meet the use environment.

[0035] The all-in-one plug-in anti-rotation bracket 1 provided in the embodiments of the present invention solves the problem of an anti-rotation bracket being unavailable for a corresponding 3-pin plug-in 2. Furthermore, the all-in-one plug-in anti-rotation bracket 1 is easy to assemble and highly versatile. It can be selected based on different connection methods for different projects. Specifically, the plug-in 2 can be a high-voltage plug-in.

[0036] In some embodiments, the mounting platform 111 is provided with a plurality of anti-rotation grooves 112 , and the openings of the plurality of anti-rotation grooves 112 face in different directions.

[0037] By setting the openings of the multiple anti-rotation grooves 112 to face different directions, multiple overlapping directions can be provided, further improving the versatility of the all-in-one plug-in anti-rotation bracket 1.

[0038] In some embodiments, at least part of the mounting platform 111 is provided with two oppositely arranged first limit plates 114, and a plug-in interface 113 is formed between the two first limit plates 114, and the two first limit plates 114 are suitable for abutting against the side walls of the pins 21 of the plug-in 2; and / or, a second limit plate 115 is provided at the end of the plug-in interface 113 on the mounting platform 111, and the second limit plate 115 is suitable for abutting against the outer wall of the fixed tube at the lower part of the pin 21 of the plug-in 2.

[0039] With this arrangement, the two oppositely arranged first limiting plates 114 can limit the pins 21 of the plug-in 2, ensuring that the pins 21 of the plug-in 2 will not be skewed when inserted into the plug-in interface 113, thereby facilitating the positioning and installation of the pins 21 of the plug-in 2 and the conductive bar 3.

[0040] A second stopper plate 115 is provided on the mounting platform 111 at the end of the plug-in interface 113. This stopper plate 115 abuts against the outer wall of the fixing barrel below the pins 21 of the plug-in 2 to determine the insertion depth of the pins 21 of the plug-in 2. When the pins 21 of the plug-in 2 abut against the second stopper plate 115, it indicates that the pins 21 of the plug-in 2 are properly inserted. At this point, the conductive bar 3 is inserted into the anti-rotation groove 112, ensuring that the mounting holes on the pins 21 and the conductive bar 3 are aligned, allowing for installation of the locking bolt 4. Specifically, the inner wall of the fixing barrel is provided with internal threads.

[0041] Specifically, in some embodiments, the second limiting plate 115 is a semi-open arc-shaped plate, the curvature of the arc-shaped plate being adapted to the fixing barrel below the pin 21, and the opening of the second limiting plate 115 facing the head end of the plug interface 113. In this way, when the pin 21 of the plug 2 is inserted into the plug interface 113, the contact area between the fixing barrel below the pin 21 and the second limiting plate 115 is larger, and the limiting effect is better.

[0042] In some embodiments, each mounting platform 111 is provided with at least two third limiting plates 116 , and a stop groove 112 is formed between adjacent third limiting plates 116 . The top of the third limiting plate 116 is higher than the top of the first limiting plate 114 .

[0043] By arranging a third limit plate 116 on the mounting platform 111, two adjacent third limit plates 116 can respectively abut against the two side walls of the conductive bar 3, so that the anti-rotation groove 112 can limit the conductive bar 3, effectively preventing the conductive bar 3 from rotating when being bolted to the pin 21 of the plug-in 2, thereby achieving an anti-rotation effect and improving the assembly stability and convenience of the plug-in 2 and the conductive bar 3.

[0044] Since the top of the third limiting plate 116 is higher than the top of the first limiting plate 114 , the conductive bar 3 can be pressed onto the pins 21 of the plug-in 2 and then fixed by the locking bolts 4 .

[0045] In some embodiments, a cover body 12 is further included. The cover body 12 includes a plurality of cover plates 121 adapted to the mounting platform 111 of the base 11 and a connecting plate 122 connecting adjacent cover plates 121 . The cover body 12 is detachably connected to the base 11 .

[0046] In some embodiments, the plurality of mounting platforms 111 are distributed in a stepped manner, and the cover plate 121 of the cover body 12 is adapted to the mounting platforms 111 .

[0047] The cover plate 121 of the cover body 12 is arranged corresponding to the mounting platform 111 of the base 11, and is used to cover the connection area after the conductive bar 3 and the pins 21 of the plug-in 2 are fixedly connected. In this way, the conductive bar 3 can be prevented from being exposed to the outside, meeting the safety requirements of IPXXB and reducing the possibility of safety accidents.

[0048] The cover 12 and the base 11 are detachably connected to facilitate subsequent maintenance and assembly, thereby improving operating efficiency.

[0049] In this embodiment, three mounting platforms 111 are provided, arranged in a stepped pattern. Accordingly, the cover body 12 is provided with three cover plates 121 and a connecting plate 122 connecting two adjacent cover plates 121. The cover plates 121 are provided in a one-to-one correspondence with the mounting platforms 111. The cover plates 121 are detachably connected to the base 11.

[0050] In this embodiment, the cover 121 and the base 11 are detachably connected via a snap-fit ​​structure.

[0051] Specifically, the snap-fit ​​structure includes a protruding lock hook 128 and an elastic lock tongue 118 adapted to the lock hook 128 . The elastic lock tongue 118 is adapted to be snap-fitted and connected with the lock hook 128 to achieve a detachable connection between the cover 12 and the base 11 .

[0052] Furthermore, at least one set of snap-fit ​​structures is provided at both the top and bottom of the cover 12 and the base 11. Specifically, in this embodiment, a raised locking hook 128 is provided on the first end surface of the top of the base 11, facing the plug-in 2, and an elastic locking tongue 118 is provided at a corresponding position on the top of the cover 12. The elastic locking tongue 118 of the cover 12 and the locking hook 128 of the base 11 are elastically engaged. A locking hook 128 is provided on the second end surface of the bottom of the base 11, facing away from the plug-in 2, and an elastic locking tongue 118 is provided at a corresponding position on the bottom of the cover 12. The two are elastically engaged.

[0053] In some embodiments, the cover 12 is divided into multiple parts, and the parts are detachably connected to the base 11 and / or adjacent parts are detachably connected via a snap-fit ​​structure.

[0054] In this embodiment, the above-mentioned snap-fit ​​structure is used to achieve elastic fastening between adjacent parts.

[0055] Furthermore, in this embodiment, the cover body 12 is divided into a first cover body 123 and a second cover body 124. The first cover body 123 includes a first cover plate, a first connecting plate, and a second cover plate connected in sequence, while the second cover body 124 includes a second connecting plate and a third cover plate connected in sequence. In the first cover body 123, an elastic locking tongue 118 is provided at the bottom of the second cover plate, and in the second cover body 124, a locking hook 128 is provided at the top of the second connecting plate. The two engage to connect the first cover body 123 and the second cover body 124.

[0056] In this embodiment, a lug 129 is provided on the top of the second connecting plate of the second cover body 124. The lug 129 is positioned toward the mounting platform 111. When the second cover body 124 is connected to the base 11, the lug 129 is hooked onto the third limiting plate 116, providing initial positioning between the second cover body 124 and the base 11. The cover plate 121 of the first cover body 123 presses against the lug 129 of the second cover body 124 and then engages with the locking hook 128 on the second connecting plate.

[0057] In some embodiments, the cover body 12 further includes a baffle 125 , which is connected to the side wall of the cover plate 121 via a fragile connector 126 , and the baffle 125 corresponds to the opening of the anti-rotation groove 112 .

[0058] By providing a baffle 125, the notch of the anti-rotation slot 112 where the conductive bar 3 is not located can be shielded, protecting the pins 21 of the plug-in 2 and the conductive bar 3. The baffle 125 is connected to the cover 121 via a brittle connector 126. At the notch of the anti-rotation slot 112 where the conductive bar 3 is located, the brittle connector 126 can be broken, removing the baffle 125 to facilitate installation of the conductive bar 3.

[0059] In some embodiments, the pins 21 of the plug-in 2 and the conductive bar 3 are fastened together by locking bolts 4 , and the mounting platform 111 is provided with grooves 117 for avoiding the locking bolts 4 ; and / or, each cover plate 121 is provided with convex bumps 127 for avoiding the locking bolts 4 .

[0060] By providing the groove 117 on the mounting platform 111 , an installation space can be provided for the rod portion of the locking bolt 4 , thereby reducing the difficulty of assembly.

[0061] By providing a convex bump 127 at a corresponding position of the cover plate 121 , an assembly space can be provided for the head of the locking bolt 4 .

[0062] In summary, the first limiting plate 114, the second limiting plate 115, the third limiting plate 116, and the groove 117 provided on the base 11 form an uneven structure. This not only achieves their respective functions but also enhances the structural strength of the base 11. Similarly, the cover plate 121 of the lid 12 is provided with a bump 127, creating an uneven structure and also enhancing the structural strength of the cover plate 121. Furthermore, a reinforcing rib is connected between the cover plate 121 and the connecting plate 122, further enhancing the structural strength of the lid 12.

[0063] In this embodiment, three mounting platforms 111 are provided, and the mounting platforms 111 are arranged in a stepped manner. The cover body 12 is divided into a first cover part 123 and a second cover part 124, which is convenient for assembly. The multi-in-one plug-in anti-rotation bracket 1 provides eight different overlapping directions for the conductive bar 3, such as Figure 5 The directions shown in F1, F2, F3, F4, F5, F6, F7 and F8 can be selected according to different overlap methods of different projects to improve versatility.

[0064] According to an embodiment of the present invention, in a second aspect, a battery pack is further provided, comprising a plug-in 2, a conductive bar 3 and the all-in-one plug-in anti-rotation bracket 1 in the above embodiment, the plug-in 2 is provided with a plurality of pins 21, the ends of the pins 21 and the ends of the conductive bar 3 are provided with mounting holes, the pins 21 are plugged into the plug-in interface 113 of the all-in-one plug-in anti-rotation bracket 1, the conductive bar 3 is provided in the anti-rotation groove 112, and the mounting hole of the conductive bar 3 corresponds to the mounting hole of the pin 21, and is connected by a locking bolt 4.

[0065] Because the battery pack includes the all-in-one plug-in anti-rotation bracket 1, it has the same effect as the all-in-one plug-in anti-rotation bracket 1, and will not be described in detail here.

[0066] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
