Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a connector bracket and an electric vehicle comprising the same. Background Art

[0002] Currently in the field of electric vehicles, the electrical connection and liquid cooling connection between the battery pack and the vehicle-end equipment need to be achieved through the vehicle-end electrical connector and the vehicle-end liquid cooling connector. In order to install the vehicle-end electrical connector and the vehicle-end liquid cooling connector, a connector bracket is usually required.

[0003] Due to the need to consider the installation space, the connector bracket and the battery pack are not close together, and there is a gap between the connector bracket and the battery pack; in addition, although the connector bracket is set in the chassis of the electric vehicle, because the vehicle-end electrical connector and the vehicle-end liquid cooling connector are exposed, there is a gap between the space inside the electric vehicle chassis and the wheels of the electric vehicle. As a result, during the driving of the electric vehicle, water, gravel and other debris rolled up by the wheels on the road may be thrown into the chassis of the electric vehicle, and then splashed into the gap between the connector bracket and the battery pack, which may easily cause the vehicle-end electrical connector and vehicle-end liquid cooling connector located here to be short-circuited by water, or be hit by debris and disconnected or damaged, affecting the normal electrical connection and liquid cooling connection between the battery pack and the vehicle-end equipment, and thus affecting the safe driving of the electric vehicle. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the vehicle-end connector is easily short-circuited by water, or disconnected or damaged by being hit by debris, and to provide a connector bracket and an electric vehicle containing the same.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A connector bracket is provided on an electric vehicle, the connector bracket comprising at least one mounting plate, the mounting plate being provided with a vehicle-end connector for docking with a battery-end connector on a battery pack;

[0007] A shielding portion is further provided on the side of the mounting plate facing the battery pack, and the shielding portion is located on at least one side of the vehicle-end connector along the length direction of the electric vehicle.

[0008] In this solution, a vehicle-end connector is provided on the mounting plate in the connector bracket. During the driving of the electric vehicle, debris such as water and gravel are thrown into the space within the chassis of the electric vehicle by the wheels and usually splash toward the vehicle-end connector in a direction opposite to the driving direction of the electric vehicle. By providing a shielding portion on the side of the mounting plate facing the battery pack, and the shielding portion is located on at least one side of the vehicle-end electrical connector along the length direction of the electric vehicle, the shielding portion can protect the vehicle-end connector in the gap between the mounting plate and the battery pack when debris splashes toward the vehicle-end connector, thereby preventing the vehicle-end connector from being short-circuited by water, being damaged by being hit by debris, or being disconnected from the battery-end connector on the battery pack, thereby ensuring the reliability of the electrical connection and / or liquid cooling connection between the battery pack and the vehicle-end equipment, and thus ensuring the safe driving of the electric vehicle.

[0009] Preferably, the mounting plate includes a first mounting surface facing the battery pack, and the shielding portion is provided on the first mounting surface;

[0010] The shielding portion extends from the first mounting surface toward the battery pack by a distance H1 , and the vehicle-end connector extends from the first mounting surface toward the battery pack by a distance H2 , where H1 > H2 .

[0011] In this solution, the first mounting surface on the mounting plate provides a physical basis for the setting of the shielding portion, and the distance that the shielding portion extends from the first mounting surface toward the battery pack is greater than the distance that the vehicle-end connector extends from the first mounting surface toward the battery pack, so that the shielding portion completely covers the vehicle-end connector in the direction extending from the first mounting surface toward the battery pack, providing better protection for the vehicle-end connector.

[0012] Preferably, the projection of the vehicle-end connector along the vertical direction does not exceed the range of the projection of the shielding portion along the vertical direction.

[0013] In this solution, through the above-mentioned structural form, the shielding portion completely shields the vehicle-end connector in the vertical direction, so that the protection effect of the shielding portion is better.

[0014] Preferably, the shielding portion includes a main body portion extending in a vertical direction and bent portions located at both ends of the main body portion, and the bent portions extend horizontally from the main body portion toward the vehicle-end connector.

[0015] In this solution, the main body extending in the vertical direction constitutes the main structure that plays a protective role in the shielding part, and the bent parts at both ends of the main body extend horizontally from the main body toward the vehicle-end connector, that is, an angle is formed between the main body and the bent parts, so as to provide support for the main body through the bent parts, reinforce the structural strength of the main body, and prevent the main body from breaking or damaging.

[0016] Preferably, flanges are provided on opposite sides of the main body and the bent portion.

[0017] In this solution, by providing the flange, the structural strength of the main body and the bent portion is enhanced, making the shielding portion more secure.

[0018] Preferably, the mounting plate is further provided with a connecting portion, and the connecting portion is used to connect the connector bracket to the beam of the electric vehicle or the quick-change bracket of the electric vehicle;

[0019] The connecting portion includes a first flange extending from one side of the mounting plate in a direction away from the battery pack. The first flange is provided with a mounting hole for allowing a connecting member to pass through and connect to the beam or the quick-change bracket.

[0020] In this solution, the first flange in the connecting portion extends in a direction away from the battery pack and has a certain extension distance, which is convenient for fitting and abutting with the quick-change bracket. The connection between the connector bracket and the quick-change bracket can be achieved by passing the connecting piece through the mounting hole on the first flange and the corresponding mounting hole on the quick-change bracket.

[0021] Preferably, the mounting plate includes a first mounting surface facing the battery pack;

[0022] The connecting portion further includes a connecting piece provided on the first mounting surface;

[0023] The connecting member includes a first fixing portion connected to the mounting plate and a second fixing portion connected to the quick-change bracket, and the first fixing portion and the second fixing portion form an angle.

[0024] In this solution, the connector includes a first fixing portion and a second fixing portion that form an angle. The first fixing portion is used to connect to the mounting plate, thereby connecting the connector to the mounting plate and also providing structural reinforcement for the mounting plate. The second fixing portion is used to connect to the quick-change bracket, further increasing the number of connection points between the connector bracket and the quick-change bracket.

[0025] Preferably, the second fixing portion is flush with the surface of the first flange.

[0026] In this solution, the surfaces of the second fixing portion and the first flange are flush with each other without any height difference, which facilitates the first flange and the connector to simultaneously fit and abut against the quick-change bracket to complete the connection, thus facilitating practical operation.

[0027] Preferably, second flanges are provided on two opposite sides of the first fixing portion.

[0028] In this solution, the second flange can be provided to reinforce the structural strength of the connecting piece, and the second flange can also support the second fixing portion, making the second fixing portion more stable.

[0029] Preferably, the connecting portion further includes a connecting plate;

[0030] The connecting plates are arranged on both sides of the mounting plate, and the connecting plates are bent from both sides of the mounting plate in a direction away from the battery pack. The connecting plates are provided with connecting holes for connecting with the quick-change bracket.

[0031] In this solution, the setting of the connecting plate further increases the connection points between the connector bracket and the quick-change bracket. The connecting plate is provided with connecting holes, which can be connected to the quick-change bracket through fasteners, thereby making the connection between the connector bracket and the quick-change bracket more firm and stable.

[0032] Preferably, the number of the connecting parts is two;

[0033] The two connecting parts are spaced apart along the length direction of the electric vehicle to form an accommodating area between the two connecting parts and the mounting plate, which is used to avoid the connecting beams between the beams in the electric vehicle and / or to make way for the connecting wiring harness of the vehicle-end connector.

[0034] In this solution, the setting of the accommodating area can play a variety of roles according to actual conditions: it can avoid the connecting beams between the beams, and can also allow the connecting wiring harness extending from the vehicle-end connector to pass through; the two connecting parts are respectively arranged at the two ends of the accommodating area, so that the connection force of the mounting plate is more balanced, which is conducive to the stable connection of the connector bracket.

[0035] Preferably, the mounting plate is further provided with a hollow portion;

[0036] The hollow portion is spaced apart from the vehicle-end connector in the length direction of the electric vehicle.

[0037] In this solution, under the premise that the mounting plate needs to be provided with a connection portion and an accommodating area, the length of the mounting plate along the length direction of the electric vehicle may exceed the necessary installation length required by the vehicle-end connector, resulting in the mounting plate being too long and there being useless space. By providing a hollow portion spaced apart from the vehicle-end connector in the direction of travel of the electric vehicle, the weight of the mounting plate can be reduced without affecting the setting of the vehicle-end connector.

[0038] Preferably, a base plate is provided at the bottom of the mounting plate, and the base plate extends from the bottom of the mounting plate in a direction away from the battery pack. The base plate is provided with positioning holes for positioning external battery exchange equipment and the electric vehicle.

[0039] In this solution, the positioning holes on the base plate facilitate the positioning of external battery replacement equipment. Setting the base plate at the bottom of the mounting plate makes the structure more compact and improves space utilization.

[0040] Preferably, the connector bracket further comprises a storage rack, and the storage rack is used to store the connection harness of the vehicle-end connector;

[0041] The storage rack is connected to a second mounting surface of the mounting plate facing away from the battery pack.

[0042] In this solution, the provision of a storage rack facilitates wire harness storage, ensuring orderliness and neatness of the wiring harness, reducing the possibility of wiring harness entanglement or snagging on other structures, and thus reducing the possibility of wiring failures, thereby ensuring the safety of the electrical and / or liquid cooling connections between the battery pack and the vehicle-side equipment. Furthermore, the storage rack is attached to the second mounting surface of the mounting plate, facing away from the battery pack, and is not restricted by the battery pack, providing a wider installation space.

[0043] Preferably, a receiving area is provided on a side of the mounting plate away from the vehicle-end connector to make room for a connecting harness of the vehicle-end connector;

[0044] The storage rack includes a connecting frame and a protective frame;

[0045] The connecting frame is a ring-shaped structure, the connecting frame is vertically connected to the mounting plate, and the connecting frame is located between the vehicle-end connector and the accommodating area;

[0046] The protection frame is connected to a side of the connection frame away from the mounting plate, and a plane where the protection frame is located and a plane where the connection frame is located form an angle.

[0047] In this solution, the connecting frame in the storage rack is located between the vehicle-end connector and the accommodating area, allowing the connecting wire harness extending from the vehicle-end connector to be arranged by the connecting frame before passing through the accommodating area. This creates a rational layout and a compact structure. The protective frame, which forms an angle with the connecting frame, limits the range of movement of the connecting wire harness, confining it between the connecting frame and the protective frame, thereby achieving the purpose of storing the connecting wire harness.

[0048] Preferably, the protection frame extends a predetermined distance in a direction away from the vehicle-end connector.

[0049] In this solution, the protection frame extends in a direction away from the vehicle-end connector so that the protection frame does not need to avoid the vehicle-end connector or the connecting wire harness extending from the vehicle-end connector, thereby reducing interference with the installation of the vehicle-end connector.

[0050] Preferably, the connector bracket includes two mounting plates arranged opposite to each other;

[0051] The two mounting plates are spaced apart by a predetermined distance to form an escape space, and the escape space is used to escape the vehicle-end connector and / or other electric vehicle accessories.

[0052] In this solution, a connector bracket comprising two opposing mounting plates is suitable for installation between two battery packs. Each mounting plate enables independent electrical and / or liquid cooling connections between the opposing battery pack and vehicle-side equipment. Furthermore, the space between the two mounting plates creates a clearing for vehicle-side connectors or other electric vehicle accessories, effectively utilizing the space and contributing to the compactness of the electric vehicle.

[0053] Preferably, the connector bracket further comprises a plurality of support members;

[0054] The support member is connected between the two mounting plates.

[0055] In this solution, the support member is connected between the two mounting plates, which can prevent the two mounting plates from deforming towards each other, moving away from each other or staggered due to external forces. This not only improves the structural strength and stability of the connector bracket itself, but also further avoids the disconnection of the vehicle-end connector due to deformation of the connector bracket.

[0056] Preferably, the number of the supporting members is two;

[0057] The support member is in the shape of a plate or a rod, and is respectively connected to the two ends of the two mounting plates in the length direction of the electric vehicle, and in the direction perpendicular to the length direction of the electric vehicle in the mounting plate, the support member is located at one end of the mounting plate close to the vehicle-end connector.

[0058] In this solution, the plate- or rod-shaped support members can achieve support for the two mounting plates with a smaller structural volume, reducing material usage. Furthermore, the support members are connected to both ends of the two mounting plates in the longitudinal direction of the electric vehicle, and are located at the end of the mounting plate near the vehicle-end connector in a direction perpendicular to the longitudinal direction of the electric vehicle. This not only improves support by connecting the support members to the ends of the mounting plates in both directions, but also allows the support members to be positioned at the end of the mounting plate near the vehicle-end connector, avoiding the need for connection, resulting in a more rational layout.

[0059] Preferably, the connector bracket further includes a baffle;

[0060] Both ends of the baffle are connected to the two support members respectively.

[0061] In this solution, by connecting a baffle between the two support members, shielding protection can be provided for the vehicle-end connector and other electric vehicle accessories arranged in the avoidance space.

[0062] Preferably, the other two ends of the baffle adjacent to the two ends connected to the support member are connected to the mounting plate.

[0063] In this solution, through the above-mentioned structural form, the baffle completely seals the end surface formed between the support member and the mounting plate, which can provide a larger shielding area for the vehicle-end connector and other accessories of the electric vehicle arranged in the avoidance space, and the protection effect is better.

[0064] An electric vehicle comprises the connector bracket described above.

[0065] In this solution, an electric vehicle equipped with the connector bracket as described above can effectively prevent the vehicle-side connector from being short-circuited due to water ingress, or being disconnected or damaged by being hit by debris, thereby ensuring the reliability of the electrical connection and / or liquid cooling connection between the battery pack and the vehicle-side equipment, thereby ensuring the safe driving of the electric vehicle.

[0066] Preferably, the electric vehicle comprises a beam, a quick-change bracket and two battery packs;

[0067] The battery pack is mounted on both sides of the beam through the quick-change bracket, and the connector bracket is located between the two battery packs.

[0068] In this solution, the two battery packs are arranged on both sides of the frame, so that the electric vehicle can replace the battery sideways, reducing the space occupied in the length direction of the vehicle body; and the space between the two battery packs can be used to install a connector bracket, which facilitates the connection between the vehicle-end connector on the connector bracket and the battery pack, and the overall layout is compact.

[0069] Preferably, the top of the connector bracket is connected to the quick-change bracket or the beam.

[0070] In this solution, the connector bracket is located below the quick-change bracket. The top of the connector bracket can be connected to the beam or quick-change bracket above the connector bracket according to actual conditions. The setting is reasonable and flexible.

[0071] The positive progress effect of the present invention is:

[0072] In the present invention, a vehicle-end connector is provided on the mounting plate in the connector bracket. During the driving of the electric vehicle, debris such as water and gravel are thrown into the space within the chassis of the electric vehicle by the wheels and usually splash toward the vehicle-end connector in a direction opposite to the driving direction of the electric vehicle. By providing a shielding portion on the side of the mounting plate facing the battery pack, and the shielding portion is located on at least one side of the vehicle-end electrical connector along the length direction of the vehicle, the shielding portion can protect the vehicle-end connector in the gap between the mounting plate and the battery pack when debris splashes toward the vehicle-end connector, thereby preventing the vehicle-end connector from being short-circuited by water, being damaged by being hit by debris, or being disconnected from the battery-end connector on the battery pack, thereby ensuring the reliability of the electrical connection and / or liquid cooling connection between the battery pack and the vehicle-end equipment, and thus ensuring the safe driving of the electric vehicle.

[0116] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0117] like Figure 1 and Figure 2 As shown, this embodiment provides an electric vehicle, including two beams 900 extending along the vehicle length direction X, a quick-change bracket 100, two battery packs 200, and a connector bracket 300. The quick-change bracket 100 is mounted on the beam 900 for detachably mounting the battery pack 200, and the area between the two beams 900 is used to accommodate the connector bracket 300.

[0118] Furthermore, two battery packs 200 are mounted on both sides of the beam 900 via quick-change brackets 100 , and the connector bracket 300 is located between the two battery packs 200 .

[0119] The two battery packs 200 are arranged on both sides of the beam 900, making full use of the space on both sides of the beam 900 to install the battery packs 200, and the space between the two battery packs 200 can be used to install the connector bracket 300, and the overall layout is compact.

[0120] like Figure 2-Figure 7 As shown, the connector bracket 300 is provided on the electric vehicle. Specifically, the connector bracket 300 includes at least one mounting plate 310. The mounting plate 310 is provided with a vehicle-end connector 320 for docking with the battery-end connector 210 on the battery pack 200; the mounting plate 310 is also provided with a shielding portion 400 on the side facing the battery pack 200, and the shielding portion 400 is located on at least one side of the vehicle-end connector 320 along the length direction X of the electric vehicle.

[0121] The mounting plate 310 in the connector bracket 300 is equipped with a vehicle-side connector 320. The vehicle-side connector 320 includes a vehicle-side electrical connector and a vehicle-side liquid-cooling connector. The connector bracket 300 is installed between two battery packs 200. The vehicle-side electrical connector and the vehicle-side liquid-cooling connector can easily mate with the battery-side connector 210 on the battery pack 200, establishing electrical and liquid-cooling connections between the battery pack 200 and the vehicle-side equipment.

[0122] During the driving of an electric vehicle, when water, gravel and other debris are thrown into the space inside the chassis of the electric vehicle by the wheels, they are usually splashed toward the vehicle-end connector 320 in the direction opposite to the driving direction of the electric vehicle. By providing a shielding portion 400 on the side of the mounting plate 310 facing the battery pack 200, and the shielding portion 400 is located on at least one side of the vehicle-end electrical connector along the vehicle length direction X, the shielding portion 400 can protect the vehicle-end connector 320 in the gap between the mounting plate 310 and the battery pack 200 when debris is splashed toward the vehicle-end connector 320, thereby preventing the vehicle-end connector 320 from being short-circuited by water, being damaged by being hit by debris, or being disconnected from the battery-end connector 210 on the battery pack 200, thereby ensuring the reliability of the electrical connection and liquid cooling connection between the battery pack 200 and the vehicle-end equipment, thereby ensuring the safe driving of the electric vehicle.

[0123] like Figure 3 As shown, in this embodiment, the shielding portion 400 is arranged on both sides of the vehicle-end connector 320 along the length direction X of the electric vehicle, so that the shielding portion 400 can provide protection for the vehicle-end connector 320 regardless of whether the electric vehicle is moving forward or reversing normally.

[0124] In other optional implementations, the shielding portion 400 may be arranged on any side of the vehicle-end connector 320 along the length direction X of the electric vehicle according to actual conditions.

[0125] Specifically, the mounting plate 310 includes a first mounting surface 311 facing the battery pack 200, and the shielding portion 400 is arranged on the first mounting surface 311; the distance that the shielding portion 400 extends from the first mounting surface 311 toward the battery pack 200 is H1, and the distance that the vehicle-end connector 320 extends from the first mounting surface 311 toward the battery pack 200 is H2, H1>H2.

[0126] The first mounting surface 311 on the mounting plate 310 provides an installation basis for the setting of the shielding portion 400, and the distance that the shielding portion 400 extends from the first mounting surface 311 toward the battery pack 200 is greater than the distance that the vehicle-end connector 320 extends from the first mounting surface 311 toward the battery pack 200, so that the shielding portion 400 completely covers the vehicle-end connector 320 in the direction extending from the first mounting surface 311 toward the battery pack 200, providing better protection for the vehicle-end connector 320.

[0127] Furthermore, the projection of the vehicle-end connector 320 along the vertical direction Z does not exceed the range of the projection of the shielding portion 400 along the vertical direction Z. Thus, the shielding portion 400 completely shields the vehicle-end connector 320 in the vertical direction Z, thereby improving the protection effect of the shielding portion 400.

[0128] Specifically, the shielding portion 400 includes a main body portion 410 extending along the vertical direction Z and bent portions 420 located at both ends of the main body portion 410 . The bent portions 420 extend horizontally from the main body portion 410 toward the vehicle-end connector 320 .

[0129] The main body 410 extending along the vertical direction Z constitutes the main structure of the shielding portion 400 that plays a protective role. The bending portions 420 at both ends of the main body 410 extend horizontally from the main body 410 toward the vehicle-end connector 320, that is, an angle is formed between the main body 410 and the bending portion 420, so as to provide support for the main body 410 through the bending portion 420, reinforce the structural strength of the main body 410, and prevent the main body 410 from breaking or damaging.

[0130] In addition, if Figure 5 As shown, flanges 430 are provided on opposite sides of the main body 410 and the bent portion 420. By providing the flanges 430, the structural strength of the main body 410 and the bent portion 420 is enhanced, making the shielding portion 400 more solid.

[0131] like Figure 2 As shown, the connector bracket 300 is located below the quick-change bracket 100. The top of the connector bracket 300 can be connected to the beam 900 or the quick-change bracket 100 located above the connector bracket 300 according to actual conditions. In this embodiment, the top of the connector bracket 300 is connected to the quick-change bracket 100.

[0132] Specifically, a connecting portion 500 is also provided on the mounting plate 310, and the connecting portion 500 is used to connect the connector bracket 300 to the quick-change bracket 100 of the electric vehicle; the connecting portion 500 includes a first flange 510 extending from one side of the mounting plate 310 in a direction away from the battery pack 200, and the first flange 510 is provided with a mounting hole 511 for allowing the connecting member 520 to pass through and connect to the quick-change bracket 100.

[0133] The first flange 510 in the connecting portion 500 extends in a direction away from the battery pack 200 and has a certain extension distance, which is convenient for fitting and abutting with the quick-change bracket 100. The connecting member 520 passes through the mounting hole 511 on the first flange 510 and the corresponding mounting hole 511 on the quick-change bracket 100, thereby realizing the connection between the connector bracket 300 and the quick-change bracket 100.

[0134] In other optional embodiments, the top of the connector bracket 300 may also be connected to the beam 900 of the electric vehicle through the connecting portion 500 .

[0135] Specifically, if Figure 6 As shown, the connecting portion 500 in this embodiment also includes a connecting member 520 provided on the first mounting surface 311; the connecting member 520 includes a first fixing portion 521 connected to the mounting plate 310 and a second fixing portion 523 connected to the quick-change bracket 100, and the first fixing portion 521 and the second fixing portion 523 form an angle.

[0136] The first fixing portion 521 is used to connect to the mounting plate 310 so that the connecting member 520 is connected to the mounting plate 310, and at the same time, the connecting member 520 also serves as a structural reinforcement for the mounting plate 310; the second fixing portion 523 is used to connect to the quick-change bracket 100 to further increase the connection points between the connector bracket 300 and the quick-change bracket 100.

[0137] Furthermore, the second fixing portion 523 is flush with the surface of the first flange 510 .

[0138] The second fixing portion 523 is flush with the surface of the first flange 510 without any height difference, which facilitates the first flange 510 and the connector 520 to simultaneously fit and abut against the quick-change bracket 100 to complete the connection, facilitating practical operation.

[0139] In addition, second flanges 522 are provided on opposite sides of the first fixing portion 521. The second flanges 522 can enhance the structural strength of the connector 520 and also support the second fixing portion 523, making the second fixing portion 523 more stable.

[0140] Furthermore, the connecting portion 500 also includes a connecting plate 530; the connecting plate 530 is arranged on both sides of the mounting plate 310, and the connecting plate 530 is bent from both sides of the mounting plate 310 in a direction away from the battery pack 200, and the connecting plate 530 is provided with a connecting hole 531 for connecting to the quick-change bracket 100.

[0141] The setting of the connecting plate 530 further increases the connection points between the connector bracket 300 and the quick-change bracket 100. The connecting plate 530 is provided with a connecting hole 531, which can be connected to the quick-change bracket 100 through a fastener 532, thereby making the connection between the connector bracket 300 and the quick-change bracket 100 more firm and stable.

[0142] In this embodiment, the number of connecting parts 500 provided on the mounting plate 310 is two; the two connecting parts 500 are spaced apart along the length direction X of the electric vehicle to form an accommodating area 600 between the two connecting parts 500 and the mounting plate 310, which is used to avoid the connecting beams between the beams 900 in the electric vehicle and / or to make way for the connecting wiring harness of the vehicle-end connector 320.

[0143] The design of the accommodating area 600 can serve multiple purposes depending on the actual situation: it can avoid the connecting beam extending along the width of the electric vehicle between the two beams and allow the connection harness extending from the vehicle-end connector 320 to pass through. Moreover, the two connecting portions 500 are respectively provided at both ends of the accommodating area 600, which ensures a more balanced force on the connection of the mounting plate 310 and facilitates a stable connection of the connector bracket 300.

[0144] Furthermore, the mounting plate 310 is further provided with a hollow portion 330 ; the hollow portion 330 is spaced apart from the vehicle-end connector 320 in the longitudinal direction X of the electric vehicle.

[0145] Under the premise that the mounting plate 310 needs to be provided with a connecting portion 500 and an accommodating area 600, the length of the mounting plate 310 along the length direction X of the electric vehicle may exceed the necessary installation length required by the vehicle-end connector 320, resulting in the mounting plate 310 being too long and there being useless space. By providing a hollow portion 330 spaced apart from the vehicle-end connector 320 in the driving direction of the electric vehicle, the weight of the mounting plate 310 can be reduced without affecting the setting of the vehicle-end connector 320.

[0146] like Figure 4 As shown, a base plate 340 is provided at the bottom of the mounting plate 310, and the base plate 340 extends from the bottom of the mounting plate 310 in a direction away from the battery pack 200. The base plate 340 is provided with a positioning hole 341 for positioning the external battery exchange equipment and the electric vehicle.

[0147] The positioning holes 341 on the base plate 340 facilitate the positioning of external battery exchange equipment. Setting the base plate 340 at the bottom of the mounting plate 310 makes the structure more compact and improves space utilization.

[0148] The connector bracket 300 further includes a storage rack 700 for storing the connection harness of the vehicle-end connector 320 ; the storage rack 700 is connected to the second mounting surface 312 of the mounting plate 310 facing away from the battery pack 200 .

[0149] The storage rack 700 facilitates wire harness storage, ensuring order and neatness, reducing the possibility of wire harness entanglement or snagging on other structures, and thus reducing wiring faults, thereby ensuring secure electrical and cooling connections between the battery pack 200 and on-board equipment. Furthermore, the storage rack 700 is attached to the second mounting surface 312 of the mounting plate 310, facing away from the battery pack 200. It is not restricted by the battery pack 200, providing a wider installation space.

[0150] Specifically, if Figure 7 As shown, the storage rack 700 includes a connecting frame 710 and a protective frame 720; the connecting frame 710 is a ring structure, the connecting frame 710 is vertically connected to the mounting plate 310, and the connecting frame 710 is located between the vehicle-end connector 320 and the accommodating area 600; the protective frame 720 is connected to the side of the connecting frame 710 away from the mounting plate 310, and the plane where the protective frame 720 is located has an angle with the plane where the connecting frame 710 is located.

[0151] The connecting frame 710 in the storage rack 700 is located between the vehicle-end connector 320 and the accommodating area 600. This facilitates the wiring harness extending from the vehicle-end connector 320 to be arranged through the connecting frame 710 before passing through the accommodating area 600, resulting in a rational layout and compact structure. The protective frame 720, which forms an angle with the connecting frame 710, limits the range of movement of the wiring harness, confining it between the connecting frame 710 and the protective frame 720, thereby effectively storing the wiring harness.

[0152] In this embodiment, the plane where the protection frame 720 is located is perpendicular to the plane where the connection frame 710 is located. In other optional implementations, the plane where the protection frame 720 is located and the plane where the connection frame 710 are located may also form other angles.

[0153] Furthermore, the protection frame 720 extends a predetermined distance in a direction away from the vehicle-end connector 320 .

[0154] The protection frame 720 extends in a direction away from the vehicle-end connector 320 so that the protection frame 720 does not need to avoid the vehicle-end connector 320 or the connecting wire harness extending from the vehicle-end connector 320, thereby reducing interference with the installation of the vehicle-end connector 320.

[0155] like Figure 3 As shown, in this embodiment, the connector bracket 300 includes two mounting plates 310 arranged opposite to each other; the two mounting plates 310 are spaced a predetermined distance apart to form an escape space 350, which is used to escape the vehicle-end connector 320 and / or other electric vehicle accessories.

[0156] The connector bracket 300, comprising two opposing mounting plates 310, is suitable for installation between two battery packs 200. Each mounting plate 310 enables independent electrical and liquid cooling connections between the corresponding battery pack 200 and on-board equipment. Furthermore, the clearance space 350 formed between the two mounting plates 310 allows for the use of a vehicle-side connector 320 or other electric vehicle accessories, effectively utilizing the space and contributing to the compactness of the electric vehicle.

[0157] In this embodiment, the structural arrangements of the two mounting plates 310 are completely consistent, so that the connector bracket 300 can be functionally symmetrically connected to the battery packs 200 on both sides.

[0158] In other optional embodiments, the structural arrangement of the two mounting plates 310 may also vary according to actual circumstances; in addition, although the connector bracket 300 is installed between the two battery packs 200, only one mounting plate 310 may be provided.

[0159] Specifically, in this embodiment, the connector bracket 300 further includes a plurality of support members 800 ; the support members 800 are connected between the two mounting plates 310 .

[0160] The support member 800 is connected between the two mounting plates 310, which can prevent the two mounting plates 310 from deforming towards each other, moving away from each other or staggered due to external force. It not only improves the structural strength and stability of the connector bracket 300 itself, but also further avoids the disconnection of the vehicle-end connector 320 due to the deformation of the connector bracket 300.

[0161] Furthermore, there are two support members 800; the shape of the support member 800 is plate-shaped or rod-shaped, and the support member 800 is respectively connected to the two ends of the two mounting plates 310 in the length direction X of the electric vehicle, and in the direction perpendicular to the length direction X of the electric vehicle in the mounting plate 310, the support member 800 is located at one end of the mounting plate 310 close to the vehicle-end connector 320.

[0162] The plate-shaped or rod-shaped support member 800 can achieve support for the two mounting plates 310 with a smaller structural volume, reducing material consumption. In addition, the support member 800 is respectively connected to the two ends of the mounting plates 310 in the longitudinal direction X of the electric vehicle, and in the direction perpendicular to the longitudinal direction X of the electric vehicle, the support member 800 is located at the end of the mounting plate 310 near the vehicle-end connector 320. This not only makes the support member 800 connected to the ends of the mounting plate 310 in both directions, providing better support, but also the support member 800 is located at the end of the mounting plate 310 near the vehicle-end connector 320, so that the arrangement of the support member 800 can avoid the arrangement of the connection portion 500, and the layout is reasonable.

[0163] Furthermore, the connector bracket 300 further includes a baffle 810 ; both ends of the baffle 810 are respectively connected to the two support members 800 .

[0164] By connecting the baffle 810 between the two support members 800 , shielding protection can be provided for the vehicle-end connector 320 and other electric vehicle accessories disposed in the avoidance space 350 .

[0165] In this embodiment, the baffle 810 extends in a horizontal direction (or substantially in a horizontal direction) to provide protection for the equipment in the avoidance space 350 in a vertically upward direction.

[0166] Furthermore, the other two ends of the baffle 810 adjacent to the two ends of the connecting support member 800 are connected to the mounting plate 310 .

[0167] Thus, the baffle 810 completely seals the end surface formed between the support member 800 and the mounting plate 310, and can provide a larger shielding area for the vehicle-end connector 320 and other accessories of the electric vehicle arranged in the avoidance space 350, thereby achieving a better protection effect.
