Description

Technical Field

[0001] The utility model 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-side equipment need to be achieved through the vehicle-side electrical connector and the vehicle-side liquid cooling connector. In order to install the vehicle-side electrical connector and the vehicle-side 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 arranged 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 in the chassis of the electric vehicle and the wheels of the electric vehicle, resulting in that during the driving of the electric vehicle, water, gravel and other debris rolled up by the wheels rotating 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 the 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. Utility Model Content

[0004] The technical problem to be solved by the utility model 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 comprising the same.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0008] In the present 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 are usually splashed 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 short-circuiting due to water ingress, 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, thereby ensuring the safe driving of the electric vehicle.

[0009] Preferably, the mounting plate comprises 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 shields the vehicle-end connector in the direction in which the first mounting surface extends toward the battery pack, thereby 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.

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

[0017] In this solution, by providing the flange, the structural strength of the main body and the bending portion is reinforced, making the shielding portion more solid.

[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, and the first flange is provided with a mounting hole for allowing a connecting member to pass through and connect with 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, so as to facilitate the fit and abutment 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 comprises a first mounting surface facing the battery pack;

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

The first fixing portion is used to connect with the mounting plate so that the connector is connected to the mounting plate, and the connector also plays a structural reinforcement role for the mounting plate; the second fixing portion is used to connect with the quick-change bracket to further increase the 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, so that the first flange and the connecting piece can be simultaneously fitted and abutted against the quick-change bracket to complete the connection, which is convenient for 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 to make the second fixing portion more stable.

[0030] The connecting plate is arranged on both sides of the mounting plate, and the connecting plate is bent from both sides of the mounting plate toward a direction away from the battery pack. The connecting plate is provided with a connecting hole 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.

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

[0033] The two connecting parts are arranged at intervals 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 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 for 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 driving direction 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, and the base plate is provided with positioning holes for positioning an external battery exchange device and the electric vehicle.

[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 storage rack is provided to facilitate the storage of the wire harness, which is conducive to ensuring the orderliness and neatness of the connection harness, reducing the possibility of the connection harness being entangled or hooked with other structures, thereby reducing the occurrence of line failures, thereby ensuring the safety of the electrical connection and / or liquid cooling connection between the battery pack and the vehicle-side equipment. In addition, the storage rack is connected to the second mounting surface of the mounting plate away from the battery pack, is not restricted by the battery pack, and has a wider installation space.

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

[0047] In this solution, the connection frame in the storage rack is located between the vehicle-end connector and the accommodating area, so that the connection harness extending from the vehicle-end connector can be arranged by the connection frame and then pass through the accommodating area, with a reasonable layout and compact structure. The protection frame forming an angle with the connection frame limits the movement range of the connection harness, so that the connection harness is confined between the connection frame and the protection frame, so as to achieve the storage function of the connection 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 comprises 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, the connector bracket including two mounting plates arranged opposite to each other is suitable for installation between two battery packs, and the mounting plates on each side can realize independent electrical connection and / or liquid cooling connection between the battery pack and the vehicle-end device opposite to it. In addition, the avoidance space formed by the interval between the two mounting plates to avoid the vehicle-end connector or other electric vehicle accessories is reasonably utilized, which is conducive to improving the compactness of the electric vehicle structure.

[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 force. 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 of the mounting plate perpendicular to the length direction of the electric vehicle, the support member is located at one end of the mounting plate close to the vehicle-end connector.

[0058] In this solution, the plate-shaped or rod-shaped support member can achieve the support function for the two mounting plates with a smaller structural volume, reducing the material consumption. In addition, the support members are respectively connected to the two mounting plates at both ends 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, which not only makes the support member connected to the ends of the mounting plate in two directions, but also makes the support function better, and the support member is located at one end of the mounting plate close to the vehicle-end connector, so that the setting of the support member can be avoided with the setting of the connection part, and the layout is reasonable.

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

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

[0061] In this solution, by connecting a baffle between two support members, shielding and 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 as 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 by water, 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 is convenient for connecting the vehicle-end connector on the connector bracket to 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 to the beam.

[0116] The present invention will be described more clearly and completely below through embodiments in conjunction with the accompanying drawings.

[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 place the connector bracket 300.

[0118] Furthermore, two battery packs 200 are installed on both sides of the beam 900 through the quick-change bracket 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, and the space on both sides of the beam 900 is fully utilized to install the battery packs 200. 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 arranged on the electric vehicle. Specifically, the connector bracket 300 includes at least one mounting plate 310, and 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 provided with a vehicle-end connector 320, and the vehicle-end connector 320 includes a vehicle-end electrical connector and a vehicle-end liquid cooling connector. The connector bracket 300 is installed between two battery packs 200, and the vehicle-end electrical connector and the vehicle-end liquid cooling connector can be conveniently docked with the battery-end connector 210 on the battery pack 200 to achieve electrical connection and liquid cooling connection between the battery pack 200 and the vehicle-end device.

[0122] During the driving of the electric vehicle, when debris such as water and gravel are thrown into the space within 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 splashes toward the vehicle-end connector 320, thereby preventing the vehicle-end connector 320 from short-circuiting due to water ingress, 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 selected to be disposed 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 shielding portion 400 extends from the first mounting surface 311 toward the battery pack 200 by a distance H1, and the vehicle-end connector 320 extends from the first mounting surface 311 toward the battery pack 200 by a distance H2, H1>H2.

[0126] The first mounting surface 311 on the mounting plate 310 provides a mounting 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 shields the vehicle-end connector 320 in the direction in which the first mounting surface 311 extends toward the battery pack 200, thereby providing better protection for the vehicle-end connector 320.

[0127] Further, 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, so that the protection effect of the shielding portion 400 is better.

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

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

[0130] In addition, if Figure 5 As shown, the two opposite sides of the main body 410 and the bent portion 420 are provided with flanges 430. 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, so as to facilitate the fit and abutment with the quick-change bracket 100. The connecting piece 520 passes through the mounting hole 511 on the first flange 510 and the corresponding mounting hole 511 on the quick-change bracket 100, so as to realize 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, Figure 6 As shown, the connecting portion 500 in this embodiment also includes a connecting member 520 arranged 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 with the mounting plate 310 so that the connecting member 520 is connected to the mounting plate 310, and the connecting member 520 also plays a role in structural reinforcement of the mounting plate 310; the second fixing portion 523 is used to connect with 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 and the surface of the first flange 510 are flush with each other without height difference, so that the first flange 510 and the connecting piece 520 can be simultaneously fitted and abutted against the quick-change bracket 100 to complete the connection, which is beneficial to actual 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 connecting member 520 and can also support the second fixing portion 523 to make 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 arranged on the mounting plate 310 is two; the two connecting parts 500 are arranged at intervals 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, so as 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 arrangement of the accommodation area 600 can play a variety of roles according to actual conditions: it can avoid the connecting beam extending between the two beams along the width direction of the electric vehicle, and can also allow the connecting wire harness extending from the vehicle-end connector 320 to pass through. In addition, the two connecting parts 500 are respectively arranged at both ends of the accommodation area 600, so that the connection force of the mounting plate 310 is more balanced, which is conducive to the 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 length direction X of the electric vehicle.

[0145] Under the premise that the mounting plate 310 needs to be provided with a connection portion 500 and a 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 for 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 dead 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 bottom plate 340 is provided at the bottom of the mounting plate 310, and the bottom plate 340 extends from the bottom of the mounting plate 310 in a direction away from the battery pack 200. The bottom plate 340 is provided with a positioning hole 341 for positioning the external battery replacement equipment and the electric vehicle.

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

[0148] The connector bracket 300 also includes a storage rack 700, which is used to store 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 that is away from the battery pack 200.

[0149] The storage rack 700 is provided to facilitate the storage of the wire harness, which is conducive to ensuring the orderliness and neatness of the connection harness, reducing the possibility of the connection harness being entangled or hooked with other structures, thereby reducing the occurrence of line failures, thereby ensuring the safety of the electrical connection and liquid cooling connection between the battery pack 200 and the vehicle-side equipment. In addition, the storage rack 700 is connected to the second mounting surface 312 of the mounting plate 310 away from the battery pack 200, is not restricted by the battery pack 200, and has a wider installation space.

[0150] Specifically, 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 a 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 connection frame 710 in the storage rack 700 is located between the vehicle-end connector 320 and the accommodating area 600, so that the connection harness extending from the vehicle-end connector 320 can be arranged through the connection frame 710 and then pass through the accommodating area 600, with a reasonable layout and compact structure. The protection frame 720 that forms an angle with the connection frame 710 limits the movement range of the connection harness, so that the connection harness is confined between the connection frame 710 and the protection frame 720, so as to achieve the storage function of the connection harness.

[0152] In this embodiment, the plane where the protection frame 720 is located is selected to be 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 is located may also form other angles.

[0153] Further, 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 connection 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, and the escape space 350 is used to escape the vehicle-end connector 320 and / or other electric vehicle accessories.

[0156] The connector bracket 300 including two mounting plates 310 arranged opposite to each other is suitable for installation between two battery packs 200. The mounting plates 310 on each side can realize independent electrical connection and liquid cooling connection between the battery pack 200 and the vehicle-end device opposite to it. In addition, the avoidance space 350 formed between the two mounting plates 310 to avoid the vehicle-end connector 320 or other electric vehicle accessories is reasonably utilized, which is conducive to improving the compactness of the electric vehicle structure.

[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 conditions; in addition, although the connector bracket 300 is installed between 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 toward each other, away from each other or offset from each other due to external force. This not only improves the structural strength and stability of the connector bracket 300 itself, but also further prevents the vehicle-end connector 320 from being disconnected due to 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 the supporting function for the two mounting plates 310 with a smaller structural volume, reducing the material consumption. In addition, 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, which not only makes the support member 800 connected to the ends of the mounting plate 310 in two directions, and the supporting function is better, but also the support member 800 is located at one end of the mounting plate 310 close to the vehicle-end connector 320, so that the setting of the support member 800 can be avoided with the setting of the connection part 500, and the layout is reasonable.

[0163] Furthermore, the connector bracket 300 further includes a baffle 810 ; two ends of the baffle 810 are respectively connected to the two supporting 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 protective effect.

[0168] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
