In addition, in the description with reference to the drawings, the same reference numerals in different drawings denote the same elements.

According to a first aspect of the present disclosure, a high voltage connector holder for a battery pack is provided. Referring to fig. 1 to 6, the high-voltage connector bracket includes: the mounting plate 110 is provided with a first surface and a second surface which are oppositely arranged, the first surface is provided with a mounting platform 111 for mounting the high-voltage connector, and the first surface is used for being attached to the upper shell 200 of the battery pack; and a support plate 120 having a first end for being detachably coupled to the mounting plate 110 and a second end opposite to the first end for being detachably coupled to the lower case 300 of the battery pack, wherein the support plate 120 has a bent portion 121 between the first and second ends to allow relative displacement between the first and second ends of the support plate 120.

Through the above technical scheme, that is, the high-voltage connector bracket for a battery pack provided by the present disclosure, utilizes the bending part 121 of the support plate 120 to enable the first end of the support plate 120 for connecting with the mounting plate 110 and the second end for connecting with the lower housing 300 to generate relative displacement therebetween, so as to absorb the fit tolerance between the lower housing 300, the high-voltage connector bracket and the upper housing 200, and further prevent the upper housing 200 from being damaged by the pulling force caused by the fit tolerance. Specifically, after the high-voltage connector is mounted on the mounting platform 111 of the mounting plate 110, the second end of the support plate 120 is connected to the lower casing 300, so that the support function and the pre-positioning function can be achieved, the mounting position of the mounting plate 110 and the mounting position of the upper casing 200 are accurate, then the first surface of the mounting plate 110 is attached to the upper casing 200 of the battery pack, and the high-voltage connector penetrates through the through hole 210 of the upper casing 200, so that the high-voltage connector can be connected with an electric component outside the battery pack. At this time, since the support plate 120 is provided with the bent portion 121, the fitting tolerance between the upper case 200 and the high-voltage connector holder and the lower case 300 can be absorbed by the bending of the support plate 120, so that the upper case 200 is subjected to only a small pulling force, and the upper case 200 can be prevented from being damaged by the pulling. In conclusion, the high-voltage connector support for the battery pack provided by the disclosure can absorb the fit tolerance between the upper shell 200, the high-voltage connector support and the lower shell 300, prevent the upper shell 200 from being damaged by the pulling force caused by the fit tolerance, and has the advantages of convenience in mounting and positioning and high assembly efficiency.

Specifically, referring to fig. 1, when the high-voltage connector and the high-voltage connector bracket are mounted at the rear end of the battery pack, that is, the first surface of the mounting plate 110 is attached to the rear end surface of the upper housing 200 of the battery pack, the supporting plate 120 can absorb the fitting tolerance in the X direction and the Z direction through the bending portion 121, so that the upper housing 200 is subjected to only a small pulling force, and the upper housing 200 can be prevented from being damaged by pulling.

The bent portion 121 may be configured in any suitable manner, for example, in some embodiments, as shown with reference to fig. 4, the bent portion 121 may be configured as an arc-shaped structure protruding from the support plate 120. Thus, the arcuate structure can better absorb the fit tolerance and reduce the pulling force on the upper housing 200. Wherein the arc of the arc structure may be configured as a circular arc or an elliptical arc, which is not limited by the present disclosure.

In some embodiments, referring to fig. 3, the second surface of the mounting plate 110 is provided with a mounting post 112, the support plate 120 is provided with a first mounting hole 122 adapted to the mounting post 112, and the mounting post 112 and the first mounting hole 122 are detachably connected by a first fastener 130. Specifically, the first fastening member 130 may be a bolt, and the mounting post 112 is provided with a threaded hole that is in threaded engagement with the bolt. In this way, rapid assembly of the support plate 120 and the mounting plate 110 is facilitated.

In some embodiments, referring to fig. 3 and 5, a stop strip 113 for stopping one side of the support plate 120 is disposed on the mounting post 112 to limit the rotation of the support plate 120. In this way, the limiting bar 113 can prevent the support plate 120 from rotating during or after installation, so as to facilitate installation of the support plate 120, and meanwhile, the support plate 120 is installed behind the lower housing 300, so as to ensure accurate positioning of the mounting plate 110 and the upper housing 200.

In some embodiments, referring to fig. 3 and 5, the number of the limiting bars 113 is two and the limiting bars are arranged on the mounting post 112 at intervals. In this way, when the supporting plate 120 is installed, the supporting plate 120 is installed between the two limiting strips 113, and the two limiting strips 113 respectively stop at the two sides of the supporting plate 120, so that the supporting plate 120 can be further prevented from rotating, thereby facilitating the installation of the supporting plate 120 and ensuring the accurate positioning of the mounting plate 110 and the upper housing 200.

It is considered that there may be a fitting tolerance in the Y direction when the high-voltage connector holder is mounted on the side of the rear end face of the battery pack. Therefore, in some embodiments, as shown in fig. 1 and 4, one end of the support plate 120 for connection with the lower housing 300 is provided with a second mounting hole 123, and the second mounting hole 123 is an oblong hole and has a length direction parallel to the length direction of the mounting plate 110. Thus, when the high-voltage connector bracket is mounted on the rear end face side of the battery pack, the length direction of the mounting plate 110 is parallel to the Y direction, the second mounting hole 123 is set to be a long round hole, the position of the high-voltage connector bracket in the Y direction can be finely adjusted, the matching tolerance in the Y direction can be reduced or eliminated, the pulling force of the upper shell 200 in the Y direction can be further reduced or eliminated, and the upper shell 200 is prevented from being damaged. Wherein, the support plate 120 may be coupled to the lower case 300 through the second mounting hole 123 by a fastener such as a bolt.

In some embodiments, referring to fig. 2, the number of the supporting plates 120 is two and the supporting plates are spaced apart. Thus, the supporting strength and stability can be enhanced, and the equipotential connection function on the lower case 300 can be realized. The supporting plate 120 may be made of a galvanized material, and may be formed by stamping a galvanized plate, for example, but the disclosure is not limited thereto.

In some embodiments, and with reference to FIG. 6, the first surface of the mounting plate 110 is provided with a sealing strip 140 disposed around the periphery of the mounting plate 110, and the mounting platform 111 is disposed in the space enclosed by the sealing strip 140. In this way, the sealing strip 140 can be sealed between the first surface of the mounting plate 110 and the inner side wall of the upper housing 200, so as to enhance the sealing performance and ensure the normal operation of the components in the battery pack.

In some embodiments, referring to fig. 6, the first surface of the mounting plate 110 is provided with a plurality of mounting bosses 114, and the mounting bosses 114 are provided with third mounting holes 115 for coupling with the upper case 200. In this way, by setting the protrusion height of the mounting boss 114, i.e., the distance between the top surface of the mounting boss 114 and the first surface of the mounting plate 110, the size of the sealing strip 140 that is compressed can be limited, and the sealing strip 140 can be ensured to achieve a good sealing effect and simultaneously prolong the service life of the sealing strip 140. The third mounting hole 115 may be a threaded hole, and the mounting plate 110 may be mounted on the upper housing 200 by passing a fastener such as a bolt through the upper housing 200 and then threadedly engaging with the threaded hole.

According to a second aspect of the present disclosure, there is also provided a battery pack including the above-mentioned high voltage connector bracket for a battery pack, and having all the advantages of the above-mentioned high voltage connector bracket, which will not be described herein again.
