Description

[0002] With the rapid development of new energy vehicles, the requirements for battery packs are also getting higher and higher. One of the most important indicators is the energy density. The lower box of the battery pack is an important structure that bears all the components inside the battery pack and is also a structure fixedly connected to the whole vehicle. Due to the large size of the mounting bracket for the connector, it is generally installed at the front or rear of the battery pack. The installation position is restricted by the size of the side beam. If the height of the side beam of the lower box is not enough, the mounting bracket for the connector cannot be installed, and the extruded profile cannot be formed.

[0003] In the related art, usually, the overall height of the side beam is increased to meet the installation requirements of the mounting bracket. This will cause an increase in the weight of the lower box, increase the use cost and the energy density of the battery pack. At the same time, the mounting bracket for the connector needs to be fixed on the side beam, and holes also need to be opened on the side beam, resulting in a weakening of the side beam structure strength and a reduction in the reliability of the battery pack.

Detailed Description of the Embodiment

[0038] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0039] The following refers to Figures 1-9 to describe a battery pack according to an embodiment of the present application.

[0040] As Figure 1 and Figure 2 shown, the battery pack of the embodiment of the present application includes: an upper box body 1, a lower box body 2, a distribution box 4, and a mounting bracket 5; the lower box body 2 and the upper box body 1 define an installation cavity 3 for accommodating battery cells; the distribution box 4 is installed in the installation cavity 3; the mounting bracket 5 is installed on the upper box body 1, and the mounting bracket 5 is provided with a mounting position 56 for installing a connector 51, and the mounting position 56 is electrically connected to the distribution box 4.

[0041] Among them, as Figure 3 shown, the mounting bracket 5 is used to fix the connector 51. The connector 51 can be a low-voltage connector, a charging connector, or a discharging connector. The mounting position 56 corresponding to the connector 51 can be the mounting position 56 of the low-voltage connector, the charging connector, or the discharging connector.

[0042] The upper box body 1 includes a top plate and side walls arranged around the top plate in the circumferential direction. The mounting bracket 5 can be arranged on the side wall or the top plate of the upper box body 1. For the convenience of description, the following takes the mounting bracket 5 being arranged on the side wall of the upper box body 1 as an example for specific description.

[0043] In this embodiment, the installation requirements of the mounting bracket 5 can be met by increasing the height of the side wall of the upper box body 1, so that the mounting bracket 5 has enough space to install various connectors 51.

[0044] In the related art, the mounting bracket is usually integrated with the lower box body. The side beam of the lower box body is relatively low and cannot meet the design requirements of the mounting bracket, resulting in limited installation scenarios. Generally, it is necessary to increase the overall height of the side beam of the lower box body to meet the installation requirements of the mounting bracket, which will increase the weight of the lower box body and increase the use cost. At the same time, the mounting bracket of the connector needs to be fixed on the side beam, and holes also need to be drilled on the side beam, resulting in a weakened structural strength of the side beam and a reduced reliability of the battery pack.

[0045] According to the battery pack provided by the embodiment of the present application, by integrating the mounting bracket 5 with the upper box body 1, on the one hand, the installation requirements of the mounting bracket 5 can be met by increasing the height of the side wall of the upper box body 1. Since the height of the upper box body 1 increases, the height of the lower box body 2 can be reduced, thereby reducing the weight of the lower box body 2, increasing the energy density by reducing the weight of the battery pack, and reducing the cost; at the same time, it is applicable to the battery pack with a very low tray border of the lower box body 2 and a composite material upper box body 1, increasing the application scenarios of the bracket installation; on the other hand, it is possible to avoid drilling holes on the side beam to install the mounting bracket 5, avoiding the situation where the structural strength of the side beam is reduced due to the installation and fixation of the mounting bracket 5, and improving the reliability of the battery pack.

[0046] In some embodiments, as Figure 3 and Figure 4As shown, the mounting bracket 5 includes: a first part 52 and a second part 53. A mounting position 56 is provided on the first part 52, and the first part 52 is connected to the upper box body 1; the second part 53 is disposed around the circumferential side of the first part 52, and one side of the second part 53 is connected to the first part 52, and the other side extends toward the direction close to the distribution box 4 and is connected to the distribution box 4.

[0047] Among them, the first part 52 is used for installing various connectors 51. The first part 52 is connected to the side wall of the upper box body 1, and the first part 52 can be connected to the side wall of the upper box body 1 by means of threaded connection, welding or bonding.

[0048] The second part 53 is used for protection and connection. The second part 53 is disposed on the circumferential side of the first part 52. The second part 53, the first part 52 and the distribution box 4 jointly define a protection space. The high-voltage power connection end of the connector 51 is located in the protection space. When an operator operates on the battery pack, the second part 53 can reduce the risk of electric shock to the operator and play a role in high-voltage protection.

[0049] The second part 53 can be continuously extended to form a continuous baffle structure, or can be arranged at intervals in a shape of a fence structure, which can be specifically defined according to the actual situation.

[0050] The first part 52 and the second part 53 can be connected by means of integral molding, welding or threaded connection.

[0051] In some embodiments, as Figure 4 shown, the second part 53 includes a bottom plate 531 and side plates 532. The bottom plate 531 is connected to the bottom end of the first part 52, and the other side extends toward the direction close to the distribution box 4 and is connected to the distribution box 4; the side plates 532 are oppositely arranged on both sides of the first part 52 and the bottom plate 531. One side of the side plate 532 is connected to the first part 52, and the other side extends toward the direction close to the distribution box 4 and is connected to the distribution box 4.

[0052] Among them, the bottom plate 531 and the side plates 532 can be connected by means of integral molding, welding or threaded connection.

[0053] The bottom plate 531 extends along the length direction of the first part 52, and one end of the bottom plate 531 is connected to the bottom of the first part 52; the side plates 532 include two oppositely arranged on both sides of the first part 52. The arrangement of the bottom plate 531 and the side plates 532 can be at the bottom and side of the first part 52 to play a protective role.

[0054] In some embodiments, as Figure 8 and Figure 9 shown, a convex portion 5311 is provided on one side of the bottom plate 531 close to the distribution box 4, and the convex portion 5311 is used for concave-convex cooperation with the groove of the distribution box 4.

[0055] It should be noted that the protrusion of the bottom plate 531 is adapted to the groove on the distribution box 4 .

[0056] In this embodiment, a groove is provided on the distribution box 4, and the protrusion provided on the bottom plate 531 is located in the groove. A groove is formed between two adjacent protrusions of the bottom plate 531, which can avoid the protrusion of the distribution box 4, so that the bottom plate 531 and the distribution box 4 form a concave-convex bite structure, which can increase the protection effect on the one hand, and play a positioning role on the other hand.

[0057] In some embodiments, Figure 4 and Figure 5 As shown, the mounting bracket 5 also includes a protective cover 54 , which is arranged opposite to the bottom plate 531 , one side of the protective cover 54 is connected to the first part 52 , and the other side extends toward the direction close to the distribution box 4 and is connected to the distribution box 4 .

[0058] The protective cover 54 extends along the length direction of the first part 52, and the protective cover 54, the first part 52 and the second part 53 jointly define a protective cavity, and at least part of the connector 51 passes through the threading cavity and is electrically connected to the distribution box 4. The protective cover 54, the bottom plate 531 and the side plate 532 protect the gap between the distribution box 4 and the first part 52 to increase the high voltage protection effect.

[0059] In some embodiments, Figure 4 As shown, the protective cover 54 has relatively arranged flanges 541 , the flanges 541 extend toward the direction close to the side plate 532 , and the flanges 541 are detachably connected to the side plate 532 .

[0060] In this embodiment, the flange 541 and the side plate 532 can be connected by threaded connection, welding or snap connection.

[0061] The protective cover 54 is provided with a flange 541 along the length direction, and the flange 541 at least partially overlaps with the side plate 532 . The provision of the flange 541 not only increases the protective effect, but also facilitates the fixation of the protective cover 54 .

[0062] In some embodiments, the flange 541 is provided with a slot, and the side panel 532 is provided with a buckle. The flange 541 and the side panel 532 are connected by the buckle to facilitate the installation and removal of the protective cover 54.

[0063] There may be a plurality of card slots, and there may be a plurality of corresponding buckles to increase the stability of the connection.

[0064] In some embodiments, the upper box body 1 is formed with a first notch, and the projection direction is the normal direction of the mounting bracket 5. The projection of the mounting position 56 falls into the projection of the first notch. The mounting bracket 5, the upper box body 1 and the mounting bracket 5 together define the mounting cavity 3.

[0065] The first notch passes through the upper box body 1 , and the first notch avoids the installation position 56 , so that the connector 51 passes through the first notch and is connected to the distribution box 4 .

[0066] At least part of the mounting bracket 5 blocks the first notch. The mounting bracket 5 can be arranged on the inner side of the upper box body 1, or on the outer side of the upper box body 1, or at the first notch. The mounting bracket 5, the upper box body 1 and the mounting bracket 5 together define a closed mounting cavity 3 to improve the airtightness of the battery pack.

[0067] In some embodiments, Figure 8 and Figure 9 As shown, the first part 52 is provided with a mounting groove 521 , the opening of the mounting groove 521 faces outside the mounting cavity 3 , and a bolt embedded part is provided in the mounting groove 521 .

[0068] Among them, the first part 52 is arranged on the inner side of the upper box body 1, the opening of the installation groove 521 faces the outside of the installation cavity 3, the installation groove 521 is a blind hole, and the first part 52 is a whole without perforation. The bolt fastener passes through the side wall of the upper box body 1 and is fastened with the bolt embedded part located in the installation groove 521, which can not only achieve the sealing of the installation cavity 3, but also achieve the fixed connection between the installation bracket 5 and the upper box body 1.

[0069] The groove depth and inner diameter of the installation groove 521 can be determined according to the type and specification of the bolt embedded part, and the setting position and setting number of the installation groove 521 can be set according to the specific application scenario.

[0070] The embedded screw sleeve 522 adopts a blind hole installation groove 521, which can improve the sealing between the installation bracket 5 and the battery pack and reduce the situation of sealing failure at the threaded hole position.

[0071] In some embodiments, Figure 8 and Figure 9 As shown, the bolt embedded part is a threaded sleeve 522 , and the connector 51 can be connected to the mounting bracket 5 by bolts through the embedded threaded sleeve 522 , so as to facilitate the installation and removal of the connector 51 relative to the mounting bracket 5 .

[0072] In some embodiments, the bolt embedded part is a metal ring 523. By embedding the metal ring 523, it is possible to reduce the situation where the mounting bracket 5 is crushed due to excessive bolt torque and the torque is attenuated after the mounting bracket 5 is aged for a long time.

[0073] The metal ring 523 may be a steel ring or an iron ring.

[0074] In some embodiments, as Figure 9 shown, the mounting bracket 5 further includes a wire harness holder 55, and the wire harness holder 55 is disposed inside the first portion 52.

[0075] The wire harness holder 55 can be a metal part or a plastic part having a wire threading hole, or can be a U-shaped bracket. The feet of the U-shaped bracket are connected to the inside of the first portion 52, and at least a part of the U-shaped bracket is spaced apart from the inside of the first portion 52 to form a wire threading hole.

[0076] The wire harness holder 55 is used to fix the wire harness on the connector 51, and reduce the situation of communication and sampling anomalies caused by wire harness wear.

[0077] One or more wire harness holders 55 can be provided. The multiple wire harness holders 55 can be correspondingly disposed on one side of the mounting position 56 of the plug-in connector, so as to facilitate fixing the wire harness on the corresponding connector 51.

[0078] In some embodiments, as Figure 7 shown, the battery pack further includes: a seal 6, the seal 6 is disposed between the mounting bracket 5 and the upper box body 1, and a second notch is provided on the seal 6, and the second notch is used to avoid the mounting position 56.

[0079] In this embodiment, the mounting bracket 5 can be disposed outside the upper box body 1 or inside the upper box body 1. The seal 6 is disposed between the upper box body 1 and the mounting bracket 5 to improve the sealing performance of the mounting bracket 5 and the battery pack and improve the connection reliability between the mounting bracket 5 and the upper box body 1.

[0080] The seal 6 can be a sealing foam or a rubber pad.

[0081] In some embodiments, as Figure 3 、 Figure 5 and Figure 7 shown, the battery pack further includes: a fixing pressing plate 7, the fixing pressing plate 7 is disposed outside the upper box body 1 and is connected to the mounting bracket 5 and the upper box body 1; a third notch is provided on the fixing pressing plate 7, and the third notch is used to avoid the mounting position 56.

[0082] In this embodiment, the fixing pressing plate 7 is disposed outside the upper box body 1. The third notch on the fixing pressing plate 7 can avoid the mounting position 56. The mounting bracket 5 is located inside the upper box body 1. The bolt sequentially passes through the fixing pressing plate 7, the upper box body 1 and the seal 6 and is fixedly connected to the bolt embedded part in the mounting bracket 5.

[0083] By providing the fixing pressing plate 7, the damage to the upper box body 1 can be reduced when the bolt torque is too large, which plays a certain protective role for the upper box body 1, and at the same time improves the connection reliability between the mounting bracket 5 and the upper box body 1.

[0084] According to the mounting bracket 5 provided by the present application, the layout position of this mounting bracket 5 for the connector 51 in the battery pack is relatively flexible, and it is applicable to both the connector 51 mounted in the Z direction and the connector 51 mounted on the horizontal plane.

In terms of structure and manufacturing, the mounting bracket 5 can be realized by die forming or integral machining. The manufacturing accuracy of the mounting bracket 5 is high and the price is cheap, which is more suitable for mass production.

[0086] According to the vehicle provided by the embodiment of the present application, by integrating the mounting bracket 5 with the upper box body 1, on the one hand, the installation requirements of the mounting bracket 5 can be met by increasing the side wall height of the upper box body 1. Since the height of the upper box body 1 increases, the height of the lower box body 2 can be reduced, thereby reducing the weight of the lower box body 2, reducing the weight of the battery pack, increasing the energy density, and reducing the cost; at the same time, it is applicable to the battery pack with a very low tray border of the lower box body 2 and a composite material upper box body 1, increasing the application scenarios of the bracket installation, reducing the weight of the battery pack, and increasing the energy density; on the other hand, it is possible to avoid drilling holes in the side beam to install the mounting bracket 5, avoiding the situation that the structural strength of the side beam is reduced due to the installation and fixation of the mounting bracket 5, and improving the reliability of the battery pack.

[0087] The embodiment of the present application also provides a mounting bracket 5. The mounting bracket 5 is mounted on the upper box body 1 of the battery pack of any one of the above embodiments. The mounting bracket 5 is provided with a mounting position 56 for mounting the connector 51, and the mounting position 56 is electrically connected to the distribution box 4.

[0088] According to the mounting bracket 5 provided by the embodiment of the present application, by integrating the mounting bracket 5 with the upper box body 1, on the one hand, the installation requirements of the mounting bracket 5 can be met by increasing the side wall height of the upper box body 1. Since the height of the upper box body 1 increases, the height of the lower box body 2 can be reduced, thereby reducing the weight of the lower box body 2, reducing the weight of the battery pack, increasing the energy density, and reducing the cost; at the same time, it is applicable to the battery pack with a very low tray border of the lower box body 2 and a composite material upper box body 1, increasing the application scenarios of the bracket installation, reducing the weight of the battery pack, and increasing the energy density; on the other hand, it is possible to avoid drilling holes in the side beam to install the mounting bracket 5, avoiding the situation that the structural strength of the side beam is reduced due to the installation and fixation of the mounting bracket 5, and improving the reliability of the battery pack.
