Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage battery boxes, and in particular relates to a connection structure of a liquid cooling plate. Background Art

[0002] The energy storage battery box usually consists of two parts, a box cover and a bottom. The box cover can be fixedly installed on the bottom through standard parts (connectors), and the bottom is a liquid cooling plate. In addition, other components, such as module mounting beams, can also be installed on the liquid cooling plate through standard parts.

[0003] Since the installation of standard parts requires a certain height of space, in order to install standard parts on the liquid cooling plate and finally connect the box cover and other components, the height of the mounting beam should be reduced as much as possible to save the overall material of the liquid cooling plate, while preventing the liquid from flowing out. The traditional solution is to set a solid part at the relevant position of the liquid cooling plate, and set a corresponding connection hole on the solid part, and one end of the standard part passes through the connection hole. Therefore, setting a solid part will greatly increase the material of the liquid cooling plate, and because the connection hole is directly set on the liquid cooling plate, the air tightness of the liquid cooling plate will be affected during long-term use, that is, the air tightness of the liquid cooling plate is poor. In order to meet the space requirements for the installation of standard parts, some traditional solutions set the mounting beam height higher, which will increase the overall material of the liquid cooling plate and the cost is higher. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model aims to provide a connection structure of a liquid cooling plate.

[0005] The technical solution adopted by the utility model is:

[0006] A connection structure of a liquid cooling plate comprises a liquid cooling plate, wherein a beam is arranged at a corresponding position of the liquid cooling plate, the beam is fixed to the liquid cooling plate by welding or integral molding, standard parts are arranged on the beam, and the beam can be connected to other parts through the standard parts.

[0007] In some embodiments, a circular hole is provided on the beam, and the standard part includes a columnar portion and a flange portion, the columnar portion extends out of the circular hole, the upper end surface of the flange portion overlaps the lower side surface of the beam, and the lower end surface of the flange portion overlaps the upper end surface of the liquid cooling plate. Thus, the standard part can be longitudinally positioned in this way.

[0008] In some embodiments, the cross section of the flange of the standard part is circular, and the standard part is fixed to the beam by riveting or welding. Thus, in this way, the standard part can be fixed to the beam to prevent the standard part from axially rotating and affecting its use.

[0009] In some embodiments, the cross section of the flange of the standard part is square, and a groove is formed on the lower side of the beam, and the two sides of the groove can abut against the flange of the flange. Thus, in this way, the standard part and the beam can be fixed to prevent the standard part from axial rotation and affecting the use.

[0010] In some embodiments, there are four beams, namely a front beam, a rear beam, a left beam and a right beam. Thus, the number and position of the beams can be set according to the actual installation position.

[0011] In some embodiments, the left beam and the right beam are welded or integrally formed on the liquid cooling plate, and the front beam and the rear beam are fixed to the liquid cooling plate by welding. Thus, the arrangement of the beams can be set according to the actual shape and structure of the liquid cooling plate.

[0012] The beneficial effects of the utility model are as follows: the utility model arranges standard parts on the beam, and then arranges the beam on the liquid cooling plate by welding / integrated molding. Therefore, there is no need to drill holes and arrange standard parts on the liquid cooling plate, the height of the beam is lower, and the cover plate and other components can also be connected with the standard parts arranged on the beam through standard parts, that is, the cover plate and other components can be fixed together with the liquid cooling plate.

[0013] Since the standard parts installed on the beam are firm and reliable, compared with the traditional standard parts installation method, the installation height of the standard parts of the utility model is lower, which can greatly save material costs. During long-term use, the standard parts on the beam will not affect the liquid cooling plate. The overall airtight stability is stronger, and the comprehensive cost and effect are better.

[0025] Specifically, in this embodiment, there are two beams, namely a front beam 3 and a rear beam 4. At the same time, two module mounting beams 7 can also be arranged on the liquid cooling plate 1.

[0026] In this embodiment, the front beam 3 and the rear beam 4 can be fixed on the liquid cooling plate 1 by welding. Of course, the arrangement of the beams can also be arranged according to the actual shape and structure of the liquid cooling plate 1.

Therefore, different types of standard parts 2 can be selected according to different methods, and the height of the standard part 2 is relatively low.

The arrangement of the beams can be set according to the actual shape and structure of the liquid cooling plate 1.

[0035] The specific installation method of the standard part 2 of the utility model is described in detail below. In this embodiment, a front beam 3 and a rear beam 4 are respectively arranged at the front end and the rear end of the liquid cooling plate 1, and a left beam 5 and a right beam 6 are respectively formed integrally on the left and right sides of the liquid cooling plate 1.

Of course, other components, such as the module installation beam, can also be installed on the beam in this way. In addition, other components that need to be connected to the energy storage battery can also be installed on the beam in this way.
