[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Figure 1 This is a schematic diagram showing the positional structure of the battery module retaining strip and the battery tray, as shown below. Figure 1 As shown, the battery module 3 is located in the center of the battery tray 4, and the battery module pressure strip 2 is located above the battery module 3. Figure 2 This is a schematic diagram of the battery module clamping strip. Protrusions 21 are provided at each of the four corners of the clamping strip 2, and clamping holes 211 are provided on each protrusion 21. The battery module 3 is fixed to the battery tray 4 via the clamping strip 2. Currently, the battery module clamping strip 2 is installed by directly passing bolts 5 through the clamping holes 211 and fixing them to the side beam 41 of the battery tray 4. However, during the battery module installation and production process, the clamping strip is prone to twisting, leading to poor process quality, such as clamping strip warping, clamping strip deformation, and poor torque retention. To solve this problem, this utility model provides a mechanism for installing battery module clamping strips.

[0027] Figure 3 This is a schematic diagram of the mechanism for installing the battery module clamping strip provided by this utility model, as shown below. Figure 3 As shown, the mechanism includes: a tooling body 1, on which a limiting mechanism 11 is provided; the limiting mechanism 11 is used to limit the back-and-forth movement of the protrusion 21 of the battery module pressure bar 2.

[0028] Specifically, Figure 4 The diagram shows the installation process of the battery module pressure strip. First, place the battery module pressure strip 2 on the battery module 3 and align the position of the pressure strip hole 211 with the position of the screw hole 411 on the side beam 41. Then, place the tooling body 1 of this application on the side beam 41, so that the protrusion 21 is between the tooling body 1 and the side beam 41. The tooling body 1 limits the protrusion 21 so that the protrusion 21 will not move up, down, left, or right. Finally, pass the bolt 5 vertically through the pressure strip hole 211 to fix the protrusion 21 on the side beam 41.

[0029] The mechanism for installing battery module pressure strips provided by this utility model first limits the protrusion of the battery module pressure strip by using the tooling body, and then fixes the protrusion of the battery module pressure strip to the side beam by bolts. This avoids twisting phenomena such as pressure strip warping, pressure strip deformation, and poor torque retention rate that occur during the installation of battery module pressure strips, so that the battery module pressure strip can more reliably and securely fix the battery module.

[0030] Furthermore, such as Figure 3 As shown, the limiting mechanism 11 includes a limiting groove 111 and a mounting through hole 112; the mounting through hole 112 is vertically arranged and passes through directly above the limiting groove 111.

[0031] During installation, the protrusion 21 of the battery module pressure strip 2 is first limited by the limiting groove 111, and then the bolt 5 is passed through the mounting hole 112 in the vertical direction and tightened with a screwdriver so that the protrusion 21 is fixed on the side beam 41, thereby achieving reliable fixing of the battery module pressure strip 2.

[0032] The mechanism for installing battery module pressure strips provided by this utility model uses the limiting groove 111 to ensure that the battery module pressure strip 2 is not rotated during installation; at the same time, the installation through hole 112 provides installation space for bolts, avoiding the use of a wrench to tighten in the horizontal direction, but instead using the sleeve action of the installation through hole 112 to tighten the bolts from the vertical direction, which greatly reduces the installation space.

[0033] Furthermore, the mechanism for installing battery module pressure strips provided by this utility model also includes a positioning pin 12, which is clearance-fitted with a positioning pin hole provided on the tooling body 1.

[0034] Specifically, during the assembly process, the battery module pressure strip 2 is placed on the battery module 3, and then the tooling body 1 is inserted into the pressure strip. The positioning of the pressure strip is completed by the cooperation of the positioning pin 12 and the positioning pin hole, so that the pressure strip hole 211 and the screw hole 411 on the side beam 41 are aligned. At the same time, the limiting groove 111 holds the pressure strip body through the protrusion 21, and then the bolt 5 is used for tightening. The battery module pressure strip 2 will not be subjected to force and rotate.

[0035] The mechanism for installing battery module clamping strips provided by this utility model has a clearance fit between the positioning pin 12 and the positioning pin hole provided on the tooling body 1, which ensures that the tooling body 1 is easy to disassemble and assemble during use. After one battery module clamping strip is tightened, the positioning pin 12 can be pulled out, and the tooling body 1 can be taken out for the installation of the next battery module clamping strip 2, which makes the installation of the battery module clamping strip 2 faster and simplifies the installation process of the battery module clamping strip.

[0036] Furthermore, the mechanism for installing battery module pressure strips provided by this utility model has an inverted U-shaped limiting groove 11, the width of which is adapted to the width of the protrusion 21.

[0037] Specifically, this application uses an inverted U-shaped limiting groove 11 to confine the protrusion 21 within a certain height range, preventing any protrusion 21 on the battery module retaining strip 2 from tilting upwards excessively due to unforeseen circumstances. Furthermore, designing the width of the limiting groove 111 to match the width of the protrusion 21 further prevents excessive lateral movement of the protrusion 21. This makes the fastening of the battery module retaining strip 2 more reliable.

[0038] Furthermore, the mechanism for installing battery module pressure strips provided by this utility model has a limiting mechanism on each of the left and right sides of the tooling body 1.

[0039] The mechanism for installing battery module clamping strips provided by this utility model has a limiting mechanism on each of the left and right sides of the tooling body 1, so that the four protrusions 21 on the battery module clamping strip 2 can be effectively limited, thereby making the fastening of the battery module clamping strip 2 more reliable.

[0040] Furthermore, the mechanism for installing battery module pressure strips provided by this utility model has at least two positioning pin holes on the tooling body 1.

[0041] The mechanism for installing battery module clamping strips provided by this utility model can make the positioning of the tooling body 1 more stable by setting at least two positioning pin holes on the tooling body 1, thereby further improving the fastening reliability of the battery module clamping strip 2.

[0042] Furthermore, the mechanism for installing battery module pressure strips provided by this utility model has two positioning pin holes disposed between two limiting mechanisms.

[0043] The mechanism for installing battery module pressure strips provided by this utility model effectively reduces the lateral length of the tooling body by setting two positioning pin holes between two limiting grooves 111, making the tooling body easier to use.

[0044] Furthermore, the tooling body 1 of the mechanism for installing the battery module pressure strip provided by this utility model is made of metal or synthetic polymer material.

[0045] Specifically, the material used to prepare the tooling body 1 can be a metallic material, such as iron or steel; it can also be a synthetic polymer material, such as plastic or composite material; or, for example, epoxy glass fiber.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
