Description

Technical Field

[0001] This invention relates to an electrical connector assembly and a battery pack comprising the same. Background Technology

[0002] Currently, vehicle exhaust emissions remain a significant contributor to environmental pollution. To address this issue, researchers have developed natural gas vehicles, hydrogen fuel cell vehicles, solar-powered vehicles, and electric vehicles to replace gasoline-powered cars. Among these, electric vehicles hold the most promising potential. Current electric vehicles primarily fall into two categories: direct-charging and quick-swapping. Due to limitations in charging time and location, many new energy electric vehicles are gradually adopting a rapid battery swapping system for energy replenishment. Currently, battery packs utilize a box-like structure with pre-installed electrical connectors for matching and power supply connections. However, different battery pack models and vehicle types result in variations in the structure and location of these connectors. The pre-installed connector matching structure on the box is difficult to accommodate these differences, leading to poor connector compatibility in existing technologies and an inability to meet the needs of various battery pack models and vehicle types. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect of poor compatibility of electrical connectors on battery packs in the prior art, and to provide an electrical connector assembly and a battery pack including the same.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] The present invention discloses an electrical connector assembly, the electrical connector assembly including an electrical connector and a housing for accommodating the electrical connector, the housing being provided with a mounting portion for connecting to a battery pack bracket.

[0006] In this solution, the aforementioned structural form is adopted, where the electrical connector is connected to the battery pack bracket as a separate module via a cover. The connection position and method of the cover and battery pack bracket can be adjusted according to the size of the battery pack and the vehicle model, without requiring extensive modifications to the battery pack bracket. This improves the compatibility of the electrical connector and facilitates the connection between the electrical connector and the battery pack bracket. Furthermore, the cover does not need to be processed together with the battery pack bracket, thus simplifying the processing of the battery pack bracket and improving processing efficiency. In addition, the cover design can prevent mud and water from splashing from the front wheels into the battery pack bracket while also reducing wind resistance.

[0007] Preferably, the housing includes a central housing and a side housing, the electrical connector is located on the central housing, and the side housing is located on the side of the central housing for accommodating at least a portion of the wires, the wires being electrically connected to the electrical connector.

[0008] In this solution, the above-mentioned structural form, with its separate central and side covers, facilitates the processing of the covers. In addition, if one of the central or side covers is damaged, only the damaged central or side cover needs to be replaced for normal use, reducing usage and replacement costs. By accommodating at least part of the wires in the side covers, the wires are not exposed to the external environment, improving safety during use.

[0009] Preferably, the central cover includes a first cover plate portion and a first bent portion extending from the first cover plate portion toward the battery pack bracket, the first cover plate portion and the first bent portion forming a receiving cavity, and the first bent portion being used to cooperate with the battery pack bracket.

[0010] In this solution, the above-mentioned structural form is adopted, and the connection between the first cover plate and the battery pack bracket is realized through the first bending part; in addition, the receiving cavity is used to accommodate the electrical connector, which improves the compactness of the structure, and the receiving cavity can protect the electrical connector and improve the service life of the electrical connector.

[0011] Preferably, the side cover includes a body and a transition portion, the transition portion being inclined relative to the body in a direction away from the battery pack bracket, and the transition portion being connected to the central cover.

[0012] In this design, the aforementioned structure forms a first accommodating cavity between the transition section and the outer wall of the battery pack bracket. One end of the wire is electrically connected to the electrical connector through this cavity. The first accommodating cavity can accommodate the wire, preventing it from being exposed to the external environment and improving safety. Since the wire needs to be bent near the electrical connector, the transition section is angled relative to the main body in the direction away from the battery pack bracket, causing the surface of the transition section to protrude from the main body. This allows the first accommodating cavity to accommodate the bend in the wire, preventing contact between the transition section and the wire and thus avoiding wear at the bend, improving safety and extending the wire's lifespan. Furthermore, the transition section is sloped or semi-sloping, reducing the contact area between the side cover and the wind, thereby reducing wind resistance.

[0013] Preferably, the transition portion includes an inclined portion, one end of which is connected to the main body portion and extends inclinedly from the main body portion away from the battery pack bracket, and the other end of which is connected to the central cover.

[0014] In this solution, the above-mentioned structural form can prevent the end of the inclined part away from the main body from contacting the wire, thereby avoiding wear on the bent part, improving the safety of use and the service life of the wire.

[0015] Preferably, the transition portion further includes an end plate portion, which is disposed at both ends of the inclined portion along the height direction of the battery pack bracket.

[0016] In this design, one end of the end plate is connected to the inclined section, and the other end of the end plate extends towards the battery pack bracket. This structural form, by connecting the end plate to the battery pack bracket, achieves a convenient connection between the side cover and the battery pack bracket.

[0017] Preferably, the transition portion further includes a connecting portion, which is parallel to the main body portion and located between the inclined portion and the central cover.

[0018] In this solution, the above-described structural form allows a first accommodating cavity to be formed between the connecting part, the inclined part, and the outer wall of the battery pack bracket. Since the connecting part is connected to the end of the inclined part furthest from the battery pack bracket, the volume of the first accommodating cavity is increased, allowing it to be adapted to the bend in the wire, thus enabling the first accommodating cavity to fully accommodate the bend in the wire.

[0019] Preferably, the main body includes a second cover plate portion and a second bent portion extending from the second cover plate portion toward the battery pack bracket, the second bent portion being provided with a first mating member, and the battery pack bracket being provided with a second mating member that mates with the first mating member.

[0020] In this design, the aforementioned structural form is adopted. The second cover plate, the second bend, and the outer wall of the battery pack bracket form a second receiving cavity, which is connected to the first receiving cavity. This allows one end of the wire to be electrically connected to the electrical connector, and the other end of the wire to pass through the first and second receiving cavities sequentially before extending into the battery pack bracket, facilitating the wire's insertion into the battery pack bracket. Furthermore, the mating connection between the first and second mating parts ensures a stable connection between the battery pack bracket and the side cover.

[0021] Preferably, of the first mating member and the second mating member, one has a protrusion and the other has a recess that mates with the protrusion.

[0022] In this solution, the above-mentioned structural form is adopted, and a stable connection between the battery pack bracket and the side cover is achieved through the cooperation of protrusions and recesses.

[0023] Preferably, the second bend is provided around the edge of the second cover plate portion, so that the second bend and the second cover plate portion form an accommodating cavity.

[0024] In this design, the aforementioned structural form increases the contact area between the second cover plate and the battery pack bracket, thereby improving connection stability. Furthermore, placing the wires within the housing cavity prevents them from being exposed to the external environment, thus enhancing safety during use.

[0025] Preferably, a buffer portion is provided between the electrical connector and the housing, the surface of the buffer portion is in contact with the electrical connector and / or the housing, and the buffer portion is elastic.

[0026] In this solution, the above-mentioned structural form is adopted. The buffer part allows the mounting surface of the electrical connector and the cover box at the end of the battery pack to act as a buffer when the vehicle accelerates and brakes, thereby avoiding direct collision between the electrical connector and the cover box and improving the service life of the electrical connector and the cover box. In addition, assuming that the plane formed by the locking shaft is the reference plane, the reference degree of the electrical connector and the reference plane can be adjusted by adjusting the tightness of the bolts to match the buffer part, which facilitates the adjustment of the electrical connector.

[0027] Preferably, the housing has a connection hole, through which the electrical connector passes.

[0028] In this solution, the above-mentioned structural form is adopted, with one end of the electrical connector extending into the battery pack bracket through the connection hole, which ensures the normal use of the electrical connector while improving the compactness of the electrical connector assembly structure.

[0029] Preferably, the mounting part further includes a mounting member, one end of which is detachably connected to the side cover box, and the other end is detachably connected to the side of the battery pack bracket.

[0030] In this solution, the aforementioned structural form increases the connection area between the side cover and the battery pack bracket through the mounting components, thereby improving the stable connection between them. Furthermore, the mounting components enable a detachable connection between the side cover and the battery pack bracket, meaning that if either the side cover or the battery pack bracket is damaged, only the damaged side cover or battery pack bracket needs to be replaced for normal operation, reducing usage and replacement costs.

[0031] Preferably, the mounting component is a U-shaped connecting plate, which includes two side plates arranged opposite each other, and the two side plates are respectively connected to the side cover box and the battery pack bracket.

[0032] In this solution, the above-mentioned structural form is adopted, and the connection between the side cover box and the battery pack bracket is realized through the U-shaped connecting plate.

[0033] Preferably, there are multiple side covers, which are symmetrically arranged on both sides of the central cover.

[0034] In this solution, the above-mentioned structural form is adopted, which allows the wires to exit from both sides of the electrical connector, improving the convenience of wire exit and reducing the length of the wires used.

[0035] The present invention further discloses a battery pack, the battery pack including a battery pack bracket and an electrical connector assembly as described above.

[0036] In this solution, by adopting the above-mentioned structural form, the electrical connector assembly is applied to the battery pack bracket device. The cover facilitates the connection between the electrical connector and the battery pack bracket, and the cover does not need to be processed together with the battery pack bracket, thus simplifying the processing of the battery pack bracket. In addition, the cover can prevent mud from the front wheels from splashing into the battery pack bracket, while also reducing wind resistance.

[0037] Preferably, the housing includes a central housing, and the battery pack further includes an adapter bracket, the central housing being connected to the battery pack bracket via the adapter bracket.

[0038] In this solution, the above-mentioned structural form is adopted, and the contact area between the middle cover box and the battery pack bracket is increased by the adapter bracket, thereby achieving a stable connection between the middle cover box and the battery pack bracket.

[0039] Preferably, the adapter bracket includes a frame body and a connecting bracket extending from the frame body, the frame body being connected to the battery pack bracket, and the connecting bracket being at least partially located within the receiving cavity of the central cover.

[0040] In this design, the aforementioned structural form creates a cavity between the central housing and the frame body via connecting brackets. This cavity accommodates the end of the electrical connector closest to the frame body, preventing direct contact between the connector and the frame body and improving the connector's safety and lifespan. Furthermore, a channel for wires to pass through is formed between adjacent connecting brackets, connecting to the accommodating cavity and facilitating wire placement.

[0041] Preferably, the adapter bracket further includes a fourth connector, and the connecting bracket is connected to the central cover box via the fourth connector;

[0042] The central cover is provided with mounting holes or mounting cylinders;

[0043] The fourth connector passes through the mounting hole or mounting cylinder to connect the central cover body to the battery pack bracket.

[0044] In this solution, the above-mentioned structural form is adopted, and the fourth connector further improves the stable connection between the central cover body and the battery pack bracket. In addition, the fourth connector enables the detachable connection between the central cover body and the battery pack bracket, so that if either the central cover body or the battery pack bracket is damaged, only the damaged central cover body or the battery pack bracket needs to be replaced for normal use, thus reducing the cost of use, replacement and processing.

[0045] Preferably, there are multiple mounting holes or mounting cylinders, and the multiple mounting holes are arranged circumferentially around the central cover body, with each mounting hole or mounting cylinder corresponding to one of the fourth connectors.

[0046] In this solution, the above-mentioned structural form is adopted, and by setting multiple mounting holes and a fourth connector, the stability of the connection between the central cover body and the battery pack bracket is improved.

[0047] The positive and progressive effects of this invention are as follows:

[0048] The electrical connector assembly of this application is mounted together with an electrical connector and a housing, which facilitates the connection and removal of the electrical connector and the battery pack bracket.

[0049] Furthermore, the housing and electrical connectors can be manufactured as separate modules in advance. They do not need to be processed together with the battery pack bracket, which simplifies the processing of the battery pack bracket and improves processing efficiency. In addition, the housing design can prevent mud and water from the front wheels from splashing into the battery pack bracket. Attached Figure Description

[0089] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0090] This embodiment provides an electrical connector assembly 100 to solve the problem that current battery packs 1000 all adopt a shell structure, and in order to install the electrical connector 1, an installation port needs to be reserved on the shell, which increases the processing difficulty of the shell and reduces the processing efficiency.

[0091] like Figures 1 to 10 As shown, the electrical connector assembly 100 includes an electrical connector 1 and a housing 2 for housing the electrical connector 1. The housing 2 is provided with a mounting part 21 for connecting to the battery pack bracket 200. Specifically, by connecting the electrical connector as a separate module to the battery pack bracket 200 through the housing 2, the connection position and method of the housing and the battery pack bracket 200 can be adjusted according to the size of the battery pack and the vehicle model, without requiring excessive changes to the battery pack bracket 200. This improves the compatibility of the electrical connector 1 and facilitates the connection between the electrical connector 1 and the battery pack bracket 200. Furthermore, the housing 2 does not need to be processed together with the battery pack bracket 200, thus simplifying the processing of the battery pack bracket 200 and improving processing efficiency. In addition, the housing 2 can prevent mud and water from splashing from the front wheels into the battery pack bracket 200 while also reducing wind resistance. In this embodiment, the cover 2 is detachably connected to the battery pack bracket 200 via the mounting part 21. This means that if either the cover 2 or the battery pack bracket 200 is damaged, only the damaged cover 2 or battery pack bracket 200 needs to be replaced for normal operation, thus reducing usage and replacement costs. In other embodiments, the cover 2 and the battery pack bracket 200 can also be connected in other ways, such as by welding. The specific form of connection between the cover 2 and the battery pack bracket 200 is not limited here.

[0092] like Figure 1As shown, the electrical connector assembly 100 also includes a first connector 3, through which the electrical connector 1 is connected to the housing 2. Specifically, one end of the electrical connector 1 passes through the connection hole 22, and the diameter of the other end of the electrical connector is larger than that of the connection hole 22, so that after the electrical connector 1 passes through the mounting hole 3002, the first connector 3 can sequentially pass through the electrical connector 1 and the housing 2, thereby realizing the connection between the electrical connector 1 and the housing 2. In addition, the first connector 3 enables a detachable connection between the electrical connector 1 and the housing 2, so that if one of the electrical connector 1 and the housing 2 is damaged, only the damaged electrical connector 1 and the housing 2 need to be replaced for normal use, reducing the cost of use and replacement.

[0093] In this embodiment, the first connector 3 is a bolt. In other embodiments, the first connector 3 may also be a screw or a pin. The specific form of the first connector 3 is not limited here.

[0094] A buffer portion is provided between the electrical connector 1 and the housing 2, and the buffer portion is elastic. The buffer portion can be provided in several ways: First, the surface of the buffer portion is in contact with the electrical connector 1; second, the surface of the buffer portion is in contact with the housing 2; third, the surface of the buffer portion is in contact with both the electrical connector 1 and the housing 2. In this embodiment, the surface of the buffer portion is in contact with both the electrical connector 1 and the housing 2, thereby allowing the mounting surfaces of the electrical connector 1 and the housing 2 at the end of the battery pack 1000 to act as a buffer during vehicle acceleration and braking, thus preventing direct collision between the electrical connector 1 and the housing 2 and improving the service life of the electrical connector 1 and the housing 2. Furthermore, assuming the plane formed by the locking shaft is a reference plane, the reference degree and perpendicularity of the electrical connector 1 and the reference plane can be adjusted by loosening or loosening the bolts to accommodate the buffer portion, facilitating the adjustment of the electrical connector 1.

[0095] like Figures 1 to 3 as well as Figure 8 As shown, a connection hole 22 is provided on the housing 2, through which the electrical connector 1 passes. With this structure, one end of the electrical connector 1 extends into the battery pack bracket 200 through the connection hole 22, ensuring normal operation of the electrical connector 1 while improving the compactness of the electrical connector assembly 100. In practical use, after the electrical connector 1 passes through the connection hole 22, the end of the electrical connector 1 away from the battery pack bracket 200 is in contact with the surface of the electrical connector 1 away from the battery pack bracket 200, thus facilitating the connection between the electrical connector 1 and the housing 2 via the first connector 3. Furthermore, this structure also improves the stability of the connection between the electrical connector 1 and the housing 2.

[0096] like Figure 1 and Figure 2As shown, the housing 2 includes a central housing 23 and a side housing 24. The electrical connector 1 is located on the central housing 23, and the side housing 24 is located on the side of the central housing 23, used to accommodate at least a portion of the wires. The wires are electrically connected to the electrical connector 1. With this structure, the side housing 24 can accommodate at least a portion of the wires, preventing them from being exposed to the external environment and improving safety. In practical use, the central housing 23 and the side housing 24 are separate units, each connected to the battery pack bracket 200, facilitating the processing and connection of the housing 2. Furthermore, the separate design means that if either the central housing 23 or the side housing 24 is damaged, only the damaged unit needs to be replaced, reducing usage and replacement costs. In other embodiments, the side housing 24 and the central housing 23 can also be integrally formed.

[0097] like Figures 1 to 3 as well as Figure 5 and Figure 8 As shown, the central housing 23 includes a first housing cover portion 231 and a first bent portion 232 extending from the first housing cover portion 231 toward the battery pack bracket 200. The first housing cover portion 231 and the first bent portion 232 form a receiving cavity, and the first bent portion 232 is used to cooperate and connect with the battery pack bracket 200. Specifically, the first housing cover portion 231 is connected to the battery pack bracket 200 through the first bent portion 232; in addition, the receiving cavity is used to accommodate the electrical connector 1, which improves the compactness of the structure, and the receiving cavity can protect the electrical connector 1, thereby improving the service life of the electrical connector 1.

[0098] In practical use, the central cover 23 is plate-shaped, and the central cover 23 is formed by a bending process to form a first bent portion 232 facing the battery pack bracket 200, thereby improving the structural strength of the central cover 23. Preferably, the first bent portion 232 is located at both ends and the top end of the first cover plate portion 231, which further improves the stability of the connection between the cover 2 and the battery pack bracket 200.

[0099] like Figure 1 and Figure 2 as well as Figure 4 and Figures 9 to 10As shown, the side cover 24 includes a main body 241 and a transition portion 242. The transition portion 242 is inclined relative to the main body 241 in a direction away from the battery pack bracket 200. The transition portion 242 is connected to the central cover 23. Specifically, a first receiving cavity is formed between the transition portion 242 and the outer wall of the battery pack bracket 200, and one end of the wire is electrically connected to the electrical connector 1 through the first receiving cavity. The first receiving cavity can accommodate the wire, preventing the wire from being exposed to the external environment and improving safety during use. Since the wire needs to be bent near the electrical connector 1, the transition portion 242 is inclined relative to the main body 241 in a direction away from the battery pack bracket 200, so that the surface of the transition portion 242 protrudes from the main body 241. This allows the first receiving cavity formed by the transition portion 242 to accommodate the bend of the wire, thereby preventing the transition portion 242 from contacting the wire and causing wear at the bend, improving safety during use and extending the service life of the wire. Furthermore, the transition section 242 is sloped or sloping, which increases the necessary wiring space at both ends of the electrical connector while minimizing the overall volume of the battery pack bracket, saving space required when the battery pack bracket is installed in the vehicle. Moreover, the slope of the transition section 242 also reduces the contact pressure between the side cover 24 and the air, thereby reducing wind resistance.

[0100] The transition section 242 includes an inclined section 2421. One end of the inclined section 2421 is connected to the main body section 241 and extends inclinedly away from the main body section 241 in a direction away from the battery pack bracket 200. The other end of the inclined section 2421 is connected to the central cover 23. This structural design prevents the end of the inclined section 2421 away from the main body section 241 from contacting the wires, thus avoiding wear at the bend and improving safety and the lifespan of the wires.

[0101] The transition portion 242 also includes an end plate portion 2422, which is disposed at both ends of the inclined portion 2421 along the height direction of the battery pack bracket 200. Specifically, one end of the end plate portion 2422 is connected to the inclined portion 2421, and the other end of the end plate portion 2422 extends toward the battery pack bracket 200. With the above structure, the connection between the side cover 24 and the battery pack bracket 200 is achieved through the connection of the end plate portion 2422 and the battery pack bracket 200, which has the advantage of convenient connection.

[0102] The transition portion 242 also includes a connecting portion 2423, which is parallel to the main body portion 241 and located between the inclined portion 2421 and the central cover 23. With this structure, a first accommodating cavity can be formed between the connecting portion 2423, the inclined portion 2421, and the outer wall of the battery pack bracket 200. Since the connecting portion 2423 is connected to the end of the inclined portion 2421 away from the battery pack bracket 200, the volume of the first accommodating cavity is increased, allowing the volume of the first accommodating cavity to be adapted to the bend in the wire, thereby enabling the first accommodating cavity to fully accommodate the bend in the wire.

[0103] In the first and second mating parts, one has a protrusion and the other has a recess that mates with the protrusion, thereby achieving a stable connection between the battery pack bracket 200 and the side cover box 24.

[0104] In practical use, the inclined part 2421, the connecting part 2423 and the main body part 241 are integrally formed, thereby increasing the structural strength of the side cover 24.

[0105] like Figure 1 and Figure 2 as well as Figure 4 and Figures 9 to 10 As shown, the main body 241 includes a second cover plate 2411 and a second bent portion 2412 extending from the second cover plate 2411 toward the battery pack bracket 200. A first mating member is provided on the second bent portion 2412, and a second mating member that mates with the first mating member is provided on the battery pack bracket 200. Specifically, the second cover plate 2411, the second bent portion 2412, and the outer wall of the battery pack bracket 200 form a second receiving cavity, which is connected to the first receiving cavity. This allows one end of a wire to be electrically connected to the electrical connector 1, and the other end of the wire to pass through the first and second receiving cavities sequentially before extending into the battery pack bracket 200, facilitating the wire's insertion into the battery pack bracket 200. Furthermore, the mating connection between the first and second mating members achieves a stable connection between the battery pack bracket 200 and the side cover 24. Specifically, the main body 241 is plate-shaped, and the main body 241 is bent to form a second bent portion 2412 facing the battery pack bracket 200, thereby improving the structural strength of the main body 241. Preferably, the second bent portion 2412 is provided at both ends and the top of the second cover plate portion 2411, which further improves the stability of the connection between the cover 2 and the battery pack bracket 200.

[0106] The second bending portion 2412 is provided around the edge of the second cover plate portion 2411, so that the second bending portion 2412 and the second cover plate portion 2411 form a receiving cavity. Specifically, the second cover plate portion 2411 can be connected to the battery pack bracket 200 through the second bending portion 2412, thereby creating a gap between the second cover plate portion 2411 and the battery pack bracket 200. Therefore, a receiving cavity for accommodating wires can be formed between the second cover plate portion 2411, the second bending portion 2412, and the outer wall of the battery pack bracket 200. The receiving cavity includes the aforementioned first receiving cavity and second receiving cavity, with the first receiving cavity being closer to the electrical connector 1 than the second receiving cavity. Since the wires need to be bent when approaching the electrical connector 1, the distance between the connecting plate and the side wall of the battery pack bracket 200 is greater than the distance between the second cover plate portion 2411 and the side wall of the battery pack bracket 200, thereby allowing the first receiving cavity to accommodate the bent portion of the wires. By adopting the above-described structure, the second bending portion 2412 increases the contact area between the second cover plate portion 2411 and the battery pack bracket 200, thereby improving the stability of the connection between the side cover 24 and the battery pack bracket 200.

[0107] like Figures 5 to 7 As shown, the mounting part 21 also includes a mounting member 211. One end of the mounting member 211 is detachably connected to the side cover 24, and the other end is detachably connected to the side of the battery pack bracket 200. With this structure, the mounting member 211 increases the connection area between the side cover 24 and the battery pack bracket 200, thereby improving the stable connection between them. Furthermore, the detachable connection between the side cover 24 and the battery pack bracket 200 via the mounting member 211 means that if either the side cover 24 or the battery pack bracket 200 is damaged, only the damaged side cover 24 or battery pack bracket 200 needs to be replaced for normal operation, reducing usage and replacement costs. In practical use, the mounting member 211 is plate-shaped, and its extension direction is the same as that of the side cover 24.

[0108] In this embodiment, the mounting component 211 is a U-shaped connecting plate, which includes two opposing side plates 2111. The two side plates 2111 are respectively connected to the side cover box 24 and the battery pack bracket 200. Using the above structural form, the connection between the side cover box 24 and the battery pack bracket 200 is achieved through the U-shaped connecting plate.

[0109] In this embodiment, the U-shaped connecting plate further includes a middle plate 2112, and the two opposite ends of the middle plate 2112 are respectively connected to the two side plates 2111 to form a U-shaped connecting plate. Preferably, the middle plate 2112 and the two side plates 2111 are integrally formed, thereby improving the structural strength of the U-shaped connecting plate. In use, the main body 241 includes a main body portion and a second bent portion 2412, and the second bent portion 2412 extends from the main body portion toward the battery pack bracket 200. The two side plates 2111 are respectively connected to the main body portion and the battery pack bracket 200, and the portion of the second bent portion 2412 near the middle plate 2112 is connected to the middle plate 2112, thereby improving the stable connection between the side cover 24 and the battery pack bracket 200. The portion of the second bent portion 2412 near the battery pack bracket 200 is also provided with a first mating member, and the first mating member and the second mating member are connected, thereby further improving the stable connection between the side cover 24 and the battery pack bracket 200. In other embodiments, the shape of the mounting component 211 may not be limited.

[0110] The mounting part 21 further includes a second connector and a third connector 212, which can be implemented in several ways. In a first embodiment, the mounting member 211 is connected to the battery pack bracket 200 via the second connector; in a second embodiment, the mounting member 211 is connected to the side cover 24 via the third connector 212; in a third embodiment, the mounting member 211 is connected to the battery pack bracket 200 via the second connector, and also to the side cover 24 via the third connector 212. In this embodiment, the mounting member 211 is connected to the battery pack bracket 200 via the second connector, and also to the side cover 24 via the third connector 212. With the above-described structure, the second connector enables a stable connection between the mounting component 211 and the battery pack bracket 200. Furthermore, the second connector also allows for a detachable connection between the mounting component 211 and the battery pack bracket 200. This means that if either the mounting component 211 or the battery pack bracket 200 is damaged, only the damaged component needs to be replaced for normal operation, reducing usage and replacement costs. Similarly, the third connector 212 enables a stable connection between the mounting component 211 and the side cover box 24. This third connector 212 also allows for a detachable connection between the mounting component 211 and the side cover box 24. This means that if either the mounting component 211 or the side cover box 24 is damaged, only the damaged component needs to be replaced for normal operation, further reducing usage and replacement costs. In practical use, the second and third connecting members 212 can be bolts. Of course, in other embodiments, the second and third connecting members 212 can also be in other forms, such as screws and pins. The specific forms of the second and third connecting members 212 are not limited here.

[0111] In practical use, the first mating part on the second bending part 2412 is mated to the second mating part on the battery pack bracket 200, and the two ends of the mounting part 211 are respectively connected to the battery pack bracket 200 and the side cover box 24, thereby further improving the stability of the connection between the battery pack bracket 200 and the side cover box 24.

[0112] The distribution of the second and third connectors 212 can be implemented in several ways. In the first implementation, there are multiple second connectors, spaced apart along the extension direction of the mounting member 211. In the second implementation, there are multiple third connectors 212, spaced apart along the extension direction of the mounting member 211. In the third implementation, there are multiple second connectors, spaced apart along the extension direction of the mounting member 211, and multiple third connectors 212, spaced apart along the extension direction of the mounting member 211. In this embodiment, there are multiple second connectors, spaced apart along the extension direction of the mounting member 211, and multiple third connectors 212, spaced apart along the extension direction of the mounting member 211, thereby improving the installation stability of the mounting member 211 and the battery pack bracket 200 through the multiple second and third connectors 212.

[0113] There are multiple side covers 24, which are symmetrically arranged on both sides of the central cover 23. Specifically, wires can exit from both sides of the electrical connector 1, allowing the wire exit position to be selected according to actual needs or the distribution position of the battery pack 1000, thereby improving the convenience of wire exit and reducing the length of the wires used.

[0114] In this embodiment, there are two side cover boxes 24, which are symmetrically arranged on both sides of the central cover box 23. In other embodiments, the number of side cover boxes 24 can be selected according to actual needs, and the specific number of side cover boxes 24 is not limited here.

[0115] This embodiment also provides a battery pack 1000, which includes a battery pack bracket 200 and an electrical connector assembly 100. By adopting the above-described structure, the electrical connector assembly 100 is applied to the battery pack bracket 200 device. The cover 2 facilitates the connection between the electrical connector 1 and the battery pack bracket 200, and the cover 2 does not need to be processed together with the battery pack bracket 200, thus simplifying the processing of the battery pack bracket 200. Furthermore, the cover 2 prevents mud from the front wheels from splashing into the battery pack bracket 200 while also reducing wind resistance.

[0116] The housing 2 includes a middle housing 23, and the battery pack 1000 also includes an adapter bracket 300. The middle housing 23 is connected to the battery pack bracket 200 through the adapter bracket 300, thus achieving a stable connection between the middle housing 23 and the battery pack bracket 200.

[0117] like Figure 3As shown, the adapter bracket 300 includes a frame body 3003 and a connecting bracket 3004 extending from the frame body 3003. The frame body 3003 is connected to the battery pack bracket 200, and the connecting bracket 3004 is at least partially located within the receiving cavity of the central cover 23. With this structure, the connecting bracket 3004 forms a cavity between the central cover 23 and the frame body 3003, which can accommodate the end of the electrical connector 1 near the frame body 3003, thereby preventing direct contact between the electrical connector 1 and the frame body 3003 and improving the safety and lifespan of the electrical connector 1. Furthermore, a channel for wires to pass through is formed between two adjacent connecting brackets 3004, and this channel communicates with the receiving cavity, facilitating wire placement.

[0118] In practical use, there are multiple connecting brackets 3004, which are symmetrically arranged on both sides of the frame body 3003, and each side of the frame body 3003 is connected to the battery pack bracket 200 on both sides. In this embodiment, there are six connecting brackets 3004, but the number of connecting brackets 3004 is not limited in other embodiments.

[0119] In this embodiment, the receiving cavity formed by the first bending portion 232 and the second cover plate portion 2411 can enclose the connecting bracket 3004, and the first cover plate portion 231 and the battery pack bracket 200 are connected by the fourth connector 3001, thereby further improving the stable connection between the middle cover 23 and the battery pack bracket 200.

[0120] The adapter bracket 300 includes a fourth connector 3001. The connecting bracket 3004 is connected to the central cover 23 via the fourth connector 3001, further improving the stable connection between the central cover 23 body 241 and the battery pack bracket 200. Furthermore, the fourth connector 3001 enables a detachable connection between the central cover 23 body 241 and the battery pack bracket 200. This means that if either the central cover 23 body 241 or the battery pack bracket 200 is damaged, only the damaged part needs to be replaced, reducing usage, replacement, and manufacturing costs. In practical use, the central cover 23 is provided with a mounting hole 3002 or a mounting sleeve; the fourth connector 3001 passes through the mounting hole 3002 or the mounting sleeve to connect the central cover 23 body 241 to the battery pack bracket 200.

[0121] In this embodiment, the mounting hole 3002 is provided on the second cover plate portion 2411, and the fourth connector 3001 passes through the mounting hole 3002 to connect the central cover plate 23 body portion 241 to the battery pack bracket 200. The mounting hole 3002 or the mounting sleeve corresponds one-to-one with the connecting bracket 3004. The fourth connector 3001 is a bolt; in other embodiments, the fourth connector 3001 may also be a screw or pin, etc. The specific form of the fourth connector 3001 is limited here. In other embodiments, the second cover plate portion 2411 may also be provided with a mounting sleeve; this is not limited here.

[0122] Multiple mounting holes 3002 or mounting cylinders are provided, spaced circumferentially around the central cover 23 body 241. Each mounting hole 3002 or mounting cylinder corresponds to a fourth connector 3001. This structural design, by providing multiple mounting holes 3002 and a fourth connector 3001, improves the stability of the connection between the central cover 23 body and the battery pack bracket 200.

[0123] In this embodiment, the electrical connector is mounted in the middle of the front of the battery pack bracket 200 via the adapter bracket 300, and is protected by the central cover 23. The side cover 24 is provided to increase the wiring space by utilizing the space in front of the battery pack bracket.

[0124] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
