[0030] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] The battery pack is usually fixed inside the existing battery module using a locking structure such as bolts. Since the battery module usually contains more battery packs, each battery pack needs to be fixed individually with evenly distributed bolts. During maintenance and overhaul, this bolt positioning and fixing structure seriously affects the overall operation time and reduces the overall efficiency during maintenance and overhaul.

[0032] See also Figures 1 to 12 , provides a battery pack mounting bracket with a quick locking function, including: a shell 10, an air blowing assembly 20 arranged inside the shell 10, an air supply mechanism 30 arranged on one side of the shell 10, and a plurality of battery packs 40 are arranged inside the shell 10.

[0033] Specifically, an airbag 25 is provided inside the inflation assembly 20, and the airbag 25 is connected to the air outlet end of the air supply mechanism 30. A plurality of positioning grooves 22 are opened on the side of the inflation assembly 20, and a positioning member 23 is inserted into the positioning groove 22. One side of the positioning member 23 contacts the battery pack 40, and the other side of the positioning member 23 contacts the airbag 25. When the air supply mechanism 30 delivers gas into the airbag 25, the airbag 25 expands to push the positioning member 23 to squeeze the battery pack 40 to complete the fixation of the battery pack 40.

[0034] The air flow is sent into the interior of the inflation assembly 20 through the air supply mechanism 30. When the inflation assembly 20 is inflated, the air flow will enter the interior of the airbag 25. As the gas continues to enter, the airbag 25 will continue to expand, and will continuously push the positioning member 23 during the expansion process. The positioning member 23 will squeeze the battery pack 40 after being pushed, thereby fixing the battery pack 40. When disassembly is required, it is only necessary to extract the gas inside the airbag 25 to retract the positioning member 23, thereby canceling the positioning and fixation of the battery pack 40.

[0035] In order to further improve the structural design of the housing 10, please refer to Figure 1 and Figure 2 The housing 10 includes a base 11 and an upper shell 12. The upper shell 12 is a shell structure with an opening at the bottom. A mounting plate 122 is provided at the edge of the lower opening of the upper shell 12. The surface of the mounting plate 122 is fixed to the base 11 by penetrating bolts.

[0036] The upper shell 12 is used as the main positioning structure, and the base 11 is used as the bottom connection and support structure. The mounting plate 122 is fixed to the base 11, so that the battery pack 40 and the related structures of the inflation assembly 20 can be positioned inside the upper shell 12. Due to the inflation requirement of the airbag 25, the structure of the upper shell 12 needs to be further improved. Before that, the related structures of the inflation assembly 20 need to be improved. Therefore, please refer to Figures 1 to 4 , as follows:

[0037] The inflation assembly 20 includes a positioning shell 21, and a positioning groove 22 is opened on the side of the positioning shell 21 close to the battery pack 40. One end of the positioning member 23 passes through the positioning groove 22 from the inside of the positioning shell 21 and contacts the battery pack 40. The airbag 25 is arranged inside the positioning shell 21, and the end of the positioning member 23 away from the battery pack 40 contacts the airbag 25.

[0038] The positioning shell 21 is used as the expansion limiting structure of the airbag 25, so that the expansion of the airbag 25 will not exceed the inner cavity of the positioning shell 21. In this way, when the internal air pressure reaches a certain level, the airbag 25 can push the positioning member 23 out, thereby realizing the clamping function through air pressure. After completing the preliminary design of the structure of the air-inflating assembly 20, it is necessary to consider the installation and design of the related structures of the air-inflating assembly 20. Based on this, please refer to Figures 1 to 4 , as follows:

[0039] Side grooves 121 are provided on both sides of the upper shell 12, and the positioning shell 21 is inserted into the interior of the upper shell 12 through the side grooves 121. A vent 251 is provided on one side of the airbag 25 close to the side groove 121, and the air outlet end of the air supply mechanism 30 is inserted into the interior of the positioning shell 21 and communicated with the vent 251.

[0040] The positioning shell 21 is installed to the interior of the upper shell 12 through a side groove 121. Such a design allows the entire upper shell 12 to be designed as a rectangular structure, and the battery packs 40 are evenly distributed in the form of rectangular blocks. In this way, it is possible to ensure that there is an airbag 25 and a positioning piece 23 on both sides of any battery pack 40 to fix the battery pack 40.

[0041] In traditional thinking, the airbag 25 cannot be used in long-term clamping work. This is because the pressure generated by the clamping will continuously react on the airbag 25, causing the airbag 25 to have a worse and worse sealing performance. Considering the force problem and service life of the airbag 25, it is necessary to improve its structure and convert the force direction of the airbag 25 to avoid the battery pack 40 generating a reaction force on the airbag 25 when the car shakes. Based on this, please refer to Figures 2 to 8 , as follows:

[0042] The positioning member 23 includes an integrally formed piston plate 231 and an insert plate 232. The inner wall of the positioning shell 21 is provided with movable cavities 24 whose number is the same as that of the piston plates 231. The piston plates 231 are sealed inside the movable cavities 24. The side of the movable cavity 24 away from the piston plate 231 is connected to the second positioning groove 22. The insert plate 232 is inserted into the movable cavity 24 and passes through the second positioning groove 22.

[0043] That is, the movement of the piston plate 231 is limited by the moving chamber 24. Figure 8 Under the structural design, the piston plate 231 can only move forward and backward. On this basis, the side wall of the battery pack 40 is fitted into the positioning shell 21, so that the battery pack can be prevented from lateral shaking. That is, during the positioning process of the battery pack 40, even if shaking occurs, no squeezing force will be generated on the piston plate 231, that is, the airbag 25 will not be squeezed. In this case, the sealing performance of the airbag 25 itself can be better maintained, and the overall service life is longer.

[0044] Under the above design, if the vehicle shakes, the battery pack 40 may vibrate up and down. To solve this vibration problem, please refer to Figures 1 to 5 Specifically, positioning ribs 41 are provided on both sides of the battery pack 40, a positioning opening 233 is opened in the middle of the plug plate 232, and positioning rods 234 are provided at the upper and lower ends of the plug plate 232. The positioning ribs 41 are inserted into the interior of the positioning opening 233, and the positioning rods 234 are respectively attached to the upper and lower end surfaces of the battery pack 40.

[0045] By providing position restrictions on the upper and lower sides of the battery pack 40 through the positioning rod 234, and combining the clamping connection between the positioning port 233 and the positioning rib 41, the position of the battery pack 40 is fixed in four directions, so that the battery pack 40 can be fixed. This connection design is always in a tight state, so the battery pack 40 cannot exert an inward squeezing force on the plug plate 232, that is, the piston plate 231 will not squeeze the airbag 25 during the clamping process, while ensuring the fixing effect of the battery pack 40, it will not affect the sealing of the airbag 25.

[0046] In the above scheme, the structures of the battery pack 40 and the air blowing assembly 20 are improved, but the upper and lower end surfaces of the battery pack 40 are not designed. As a result, the distortion force generated by the battery pack 40 when it shakes is only positioned by the positioning member 23, which causes the related structure of the positioning member 23 to be overloaded. In order to reduce the burden of the positioning member 23, please refer to Figure 1 , Figure 2 , Fig. 9 , Fig.10 and Fig.11 , as follows:

[0047] A plurality of positioning grooves 111 are provided on the upper end surface of the base 11, and a plurality of support plates 13 and support plates 2 34 are provided inside the upper shell 12, wherein one support plate 2 34 and one support plate 13 form a group, a positioning portion 131 is provided on the lower end surface of the support plate 13, and a positioning portion 2 341 is provided on the upper end surface of the support plate 2 34. Positioning grooves 111 are provided on the upper end surface of the base 11 and the surface of the upper wall inside the upper shell 12, and the positioning portion 131 is inserted into the interior of the positioning groove 111 of the base 11, and the positioning portion 2 341 is inserted into the interior of the positioning groove 111 of the upper shell 12. The battery pack 40 is provided between the support plate 13 and the support plate 2 34, and the upper end surface and the lower end surface of the battery pack 40 are respectively attached to the surfaces of the support plate 13 and the support plate 2 34.

[0048] By using the support plate 1 13 and the support plate 2 34 to support the upper and lower end surfaces of the battery pack 40, the stability of the battery pack 40 can be further enhanced while reducing the load of the positioning member 23. In addition, since there is a certain space between the support plate 1 13, the support plate 2 34 and the base 11 and the upper shell 12, as shown in FIG. Fig.11 As shown, this design can provide a buffer space when the outermost base 11 or the upper shell 12 is hit, reducing the possibility of the battery pack 40 being directly hit, thereby improving the protection effect of the battery pack 40. During installation, the bottom support plate 1 13 can be installed first, and then the battery plate 40 can be installed on the support plate 1 13, and finally the support plate 2 34 and the upper shell 12 can be installed in sequence.

[0049] On the basis of the above structural design, in order to ensure the convenience of disassembly of structural parts, please refer to Figure 1 , Figure 2 , Fig. 9 , Fig.10 and Fig.11 Specifically, a positioning cavity 132 is separated between two adjacent support plates 13, and a positioning plate 342 is provided on the side close to the two support plates 34. The two positioning plates 342 are fitted and inserted into the interior of the positioning cavity 132.

[0050] The upper positioning plate 342 is clamped by the positioning cavity 132 separated by the bottom support plate 13, thereby ensuring that each support plate 13 and support plate 2 34 are structurally independent while having strong stability, which not only facilitates subsequent disassembly, but also allows direct replacement of the structure or separate repair after disassembly if part of the structure is damaged during maintenance, which is more convenient to use.

[0051] In order to ensure that each airbag 25 can receive the gas delivered, while reducing the complexity of the structural parts, please refer to Figure 2 , Figure 3 as well as Figure 4 The air supply mechanism 30 includes a shunt pipe 31, and a plurality of branch pipes 33 are arranged on the side of the shunt pipe 31 close to the inflation assembly 20. The branch pipes 33 are connected to the airbag 25. A valve body 331 is embedded in the branch pipe 33. The side of the shunt pipe 31 away from the inflation assembly 20 is connected to the air supply pipe 32.

[0052] The gas is injected through external equipment, such as a blower and other equipment. The airflow enters through the air supply pipe 32 and enters the inside of the branch pipe 33 through the shunt pipe 31. Different from the traditional air supply method, here, since the position of the piston plate 231 is in a directional state, even if the time and speed of the airflow entering are different, it can ensure that the piston plate 231 and the plug plate 232 can be accurately inserted into the slot position where the positioning rib 41 of the battery pack 40 is located. When the airflow is injected into the interior, when the air pressure reaches the preset threshold, the gas injection can be disconnected. The threshold value of the air pressure can be tested according to the design of different sizes and vehicle models. The air pressure value after the gas pushes all the piston plates 231 and the plug plates 232 to the extreme position for a period of time is used as the threshold value. This is to ensure that the internal air pressure strength is sufficient to avoid the shaking of the piston plate 231 itself when the internal air pressure strength is insufficient, which can cause the airbag 25 to deform.

[0053] In addition, in order to facilitate the inflation and deflation at the port of the air supply pipe 32, it is necessary to consider improving the connection structure at its end. Figure 2 and Fig.12 The outer side of the end of the air supply pipe 32 away from the shunt pipe 31 is threadedly connected with an outer tube 321, and the inner side of the end of the outer tube 321 away from the air supply pipe 32 is integrally formed with an insert tube 3211, the insert tube 3211 is inserted into the interior of the air supply pipe 32, and the inner wall of the air supply pipe 32 is integrally formed with an inner tube 322, the outer surface of the insert tube 3211 fits the inner wall of the inner tube 322, the inner wall of the inner tube 322 is provided with a plurality of air grooves 3221, the inner wall of the insert tube 3211 is provided with a plurality of side grooves 3212 that penetrate to the outside, and the end of the insert tube 3211 inserted into the inner side of the inner tube 322 is in a sealed state.

[0054] By rotating, the air groove 3221 and the second side groove 3212 are in two states: connected and misaligned. Since the insert tube 3211 is a side groove 3212 opened on the side and the end is sealed, when the air groove 3221 is connected with the second side groove 3212, the external air flow can enter from the inside of the insert tube 3211, and when the air groove 3221 and the second side groove 3212 are misaligned, the connected state is disconnected to form a closed state. When designing, it is only necessary to make the state between the second side groove 3212 and the air groove 3221 misaligned when the outer tube 321 and the air supply tube 32 are fully tightened, so as to ensure the sealing of the structural installation, and insert the air pipe for injecting gas into the insert tube 3211 for gas injection. After injecting gas for a period of time, rotate the outer tube 321 until the entire outer tube 321 is fully tightened, and the entire device is now closed.

[0055] When disassembly is required, the valve body 331 on a certain branch pipe 33 can be opened separately to achieve the disassembly of the battery pack 40 on a certain side, or all the valve bodies 331 can be opened to loosen the clamping of all the battery packs 40. In addition, the base 11 can be removed, and then the support plate 13 on the base 11 is removed, and then the valve body 331 on the corresponding side is opened for a period of time and then closed again. In this way, part of the gas inside the airbag 25 will flow out, but there is still a certain amount of gas inside, so that no negative pressure adsorption state is generated on the piston plate 231. In this case, the positioning rod 234 on the plug plate 232 can be pressed inward separately to disassemble one of the battery packs 40 without affecting the positioning state of other battery packs 40. After the disassembly and replacement are completed, the gas can be injected again to re-fix it.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them. Anyone familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
