[0002] With the continuous development of new energy technologies, the automotive field has also started to design new energy vehicles. For new energy vehicles, their battery modules are one of the most important components in the vehicle. To ensure the safety of new energy vehicle battery modules during use, in the prior art, a housing covering method is usually adopted for fixation and installation, and a locking structure such as bolts is usually adopted inside the battery module. Since the inside of the battery module usually contains a large number of battery packs, this results in the need to separately fix each battery pack with evenly distributed bolts. During maintenance and repair, this bolt positioning and fixing structure seriously affects the overall operation time and reduces the overall efficiency during maintenance and repair. Summary of the Invention

The battery pack is arranged between the first support plate and the second support plate, and the upper end surface and the lower end surface of the battery pack are respectively attached to the surfaces of the first support plate and the second support plate.

[0008] As an improvement of the above technical solution, a positioning cavity is separated between two adjacent first support plates. A positioning plate is arranged on one side where two second support plates are close to each other. After the two positioning plates are attached, they are inserted into the positioning cavity.

[0009] As an improvement of the above technical solution, the air-blowing assembly includes a positioning shell. A second positioning groove is formed on one side of the positioning shell close to the battery pack. One end of the positioning member passes through the second positioning groove from the inside of the positioning shell and contacts the battery pack. The airbag is arranged inside the positioning shell, and the end of the positioning member far from the battery pack contacts the airbag.

[0010] As an improvement of the above technical solution, the positioning member includes a piston plate and an insertion plate which are integrally formed. Moving cavities with the same number as the piston plates are formed on the inner wall of the positioning shell. The piston plate is hermetically arranged inside the moving cavity. The side of the moving cavity far from the piston plate is communicated with the second positioning groove. The insertion plate is inserted into and penetrates through the second positioning groove from the moving cavity.

[0011] As an improvement of the above technical solution, positioning ribs are arranged on both sides of the battery pack. A positioning opening is formed in the middle position of the insertion plate. Positioning rods are arranged at the upper end part and the lower end part of the insertion plate. The positioning ribs are clamped into the positioning opening, and the positioning rods are respectively attached to the upper end surface and the lower end surface of the battery pack.

[0012] As an improvement of the above technical solution, first side grooves are formed on both sides of the upper shell. The positioning shell is inserted into the upper shell from the first side grooves. An air vent is formed on one side of the airbag close to the first side grooves.

A plurality of air grooves are formed on the inner side wall of the inner tube. A plurality of side grooves two penetrating to the outside are formed on the inner wall of the insertion tube. The end of the insertion tube inserted into the inner side of the inner tube is in a sealed state. When the outer tube is fully tightened with the air delivery pipe, the side grooves two are misaligned with the air grooves.

[0015] Advantages of the present invention:

[0016] The rapid locking of the positioning member is formed by the inflation of the airbag, and then the rapid clamping and fixing of the battery pack are realized. By providing a plurality of corresponding clamping structures, the fixing of the battery packs inside the entire battery module can be achieved. And the airbag is arranged inside the air inflation assembly. In this case, the housing of the air inflation assembly itself can act as an external limiting structure, thus avoiding the problem of the airbag bursting due to excessive pressure. While ensuring the clamping function of the battery pack, it has strong stability. And during disassembly, only by pumping out the gas inside the airbag can rapid disassembly be achieved.

Detailed implementation manners

[0030] The following uses specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] In the existing battery module, a locking structure such as bolts is usually used to fix the battery pack. Since the interior of the battery module usually contains a relatively large number of battery packs, it is necessary to individually use evenly distributed bolts to fix each battery pack. When performing maintenance and repair, this bolt positioning and fixing structure seriously affects the overall operation time and reduces the overall efficiency during maintenance and repair.

[0032] Please refer to Figures 1 to 12 , there is provided a battery pack mounting bracket with a quick locking function, including: an outer shell 10, an air inflation assembly 20 arranged inside the outer shell 10, an air supply mechanism 30 arranged on one side of the outer shell 10, and a plurality of battery packs 40 arranged inside the outer shell 10.

[0033] Specifically, an airbag 25 is provided inside the air inflation assembly 20. The airbag 25 is communicated with the air outlet end of the air supply mechanism 30. A plurality of second positioning grooves 22 are formed on the side of the air inflation assembly 20. A positioning member 23 is inserted into the second positioning grooves 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 sends 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 inside of the air inflation assembly 20 through the air supply mechanism 30. When the air inflation assembly 20 is inflated, the air flow will enter the inside of the airbag 25. As the gas continuously enters, the airbag 25 will continuously expand. During the expansion process, the airbag 25 will continuously push the positioning member 23. After being pushed, the positioning member 23 will squeeze the battery pack 40, thereby forming the fixation of the battery pack 40. When disassembly is required, only by pumping out the gas inside the airbag 25 can the positioning member 23 be retracted, thereby canceling the positioning and fixation of the battery pack 40.

[0035] 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 housing 12. The upper housing 12 is a housing structure with an open lower part. An installation plate 122 is provided at the edge of the open lower part of the upper housing 12. The surface of the installation plate 122 is fixed to the base 11 through through bolts.

[0036] Taking the upper housing 12 as the main positioning structure and the base 11 as the bottom connection and support structure, and then fixing the upper housing 12 to the base 11 through the installation plate 122, the relevant structures of the battery pack 40 and the air inflation assembly 20 can be positioned inside the upper housing 12. Due to the air inflation requirement of the airbag 25, the structure of the upper housing 12 needs to be further improved. Before that, the relevant structures of the air inflation assembly 20 need to be improved. Therefore, please refer to Figures 1 to 4 as follows:

[0037] The air inflation assembly 20 includes a positioning shell 21. A second positioning groove 22 is formed on one side of the positioning shell 21 close to the battery pack 40. One end of the positioning member 23 passes through the second 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] By using the positioning shell 21 as the expansion limiting structure of the airbag 25, 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 out the positioning member 23, thus realizing the clamping function through air pressure. After the preliminary design of the structure of the air inflation assembly 20 is completed, it is necessary to consider the installation and design of the related structures of the air inflation assembly 20. Based on this, please refer to Figures 1 to 4 , specifically as follows:

[0039] On both sides of the upper shell 12, there are first side grooves 121. The positioning shell 21 is inserted into the interior of the upper shell 12 through the first side grooves 121. On one side of the airbag 25 close to the first side grooves 121, there is an air vent 251. The air outlet end of the air supply mechanism 30 is inserted into the interior of the positioning shell 21 and communicated with the air vent 251.

[0040] The positioning shell 21 is installed into the interior of the upper shell 12 through the first side grooves 121. Such a design can consider designing the entire upper shell 12 as a rectangular structure, and the battery packs 40 are evenly distributed in a rectangular grid block manner. In this way, it can be ensured that there is an airbag 25 and a positioning member 23 on both sides of any battery pack 40 to fix the battery pack 40.

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

[0042] The positioning member 23 includes a piston plate 231 and an insertion plate 232 that are integrally formed. On the inner wall of the positioning shell 21, there are moving cavities 24 with the same number as the piston plates 231. The piston plates 231 are hermetically arranged inside the moving cavities 24. The side of the moving cavity 24 away from the piston plates 231 is communicated with the second positioning grooves 22. The insertion plates 232 are inserted into and penetrate through the second positioning grooves 22 from the moving cavities 24.

[0043] That is, the movement of the piston plates 231 is restricted by the moving cavities 24. Under the structural design as in Figure 8 , the piston plates 231 can only move back and forth. On this basis, the side wall of the battery pack 40 is attached to the positioning shell 21. In this way, the lateral shaking of the battery pack can be avoided. That is, during the positioning process of the battery pack 40, even if there is shaking, it will not generate a squeezing force on the piston plates 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 scheme design, when 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 port 233 is opened in the middle position of the plug board 232, and positioning rods 234 are provided at the upper and lower ends of the plug board 232. The positioning ribs 41 are snapped into the inside of the positioning port 233, and the positioning rods 234 are respectively attached to the upper and lower end faces of the battery pack 40.

[0045] By providing position limitations on the upper and lower sides of the battery pack 40 through the positioning rods 234, and combining with the snap connection between the positioning port 233 and the positioning ribs 41, the position of the battery pack 40 is fixed in four directions, so that the battery pack 40 can be fixed. And this connection design is always in a tightly attached state. Therefore, the battery pack 40 cannot exert an inward squeezing force on the plug board 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 performance of the airbag 25.

[0046] In the foregoing scheme, the structures of the battery pack 40 and the air inflation assembly 20 are improved, but the upper and lower end faces of the battery pack 40 are not designed. This results in that the torsional force generated when the battery pack 40 shakes is only positioned by the positioning member 23, which will cause an excessive burden on the relevant structures of the positioning member 23. To reduce the burden on the positioning member 23, please refer to Figure 1 、 Figure 2 、 Figure 9 、 Figure 10 And Figure 11 , specifically as follows:

[0047] A plurality of first positioning grooves 111 are opened on the upper end face of the base 11. A plurality of first support plates 13 and second support plates 34 are arranged inside the upper housing 12. One second support plate 34 and one first support plate 13 form a group. A first positioning portion 131 is arranged on the lower end face of the first support plate 13, and a second positioning portion 341 is arranged on the upper end face of the second support plate 34. First positioning grooves 111 are opened on the upper end face of the base 11 and the surface of the upper inner wall of the upper housing 12. The first positioning portion 131 is inserted into the first positioning groove 111 of the base 11, and the second positioning portion 341 is inserted into the first positioning groove 111 of the upper housing 12. The battery pack 40 is arranged between the first support plate 13 and the second support plate 34, and the upper and lower end faces of the battery pack 40 are respectively attached to the surfaces of the first support plate 13 and the second support plate 34.

[0048] By using the first support plate 13 and the second support plate 34 to support the upper and lower end faces of the battery pack 40, while further strengthening the stability of the battery pack 40, the load on the positioning member 23 can be reduced, and since there is a certain space between the first support plate 13, the second support plate 34, the base 11, and the upper housing 12, such as Figure 11 shown, this design can provide a buffer space when the outermost base 11 or the upper housing 12 is impacted, reducing the possibility of the battery pack 40 being directly impacted, thereby improving the protection effect on the battery pack 40. During installation, the first support plate 13 at the bottom can be installed first, then the battery panel 40 can be installed on the first support plate 13, and finally the second support plate 34 and the upper housing 12 can be installed in sequence.

[0049] On the basis of the above structural design, in order to ensure the convenience of disassembling the structural members, please refer to Figure 1 、 Figure 2 、 Figure 9 、 Figure 10 and Figure 11 . Specifically, a positioning cavity 132 is separated between two adjacent first support plates 13, and positioning plates 342 are provided on one side of the two second support plates 34 close to each other. After the two positioning plates 342 are fitted, they are inserted into the interior of the positioning cavity 132.

[0050] The positioning plates 342 above are clamped by the positioning cavities 132 separated between the first support plates 13 at the bottom, so as to ensure that each first support plate 13 and the second support plate 34 are structurally independent and have strong stability at the same time. This not only facilitates subsequent disassembly, but also during maintenance, if part of the structure is damaged, the structure can be directly replaced or repaired separately after disassembly, making it more convenient to use.

[0051] In order to ensure that each airbag 25 can receive the incoming gas while reducing the complexity of the structural members, please refer to Figure 2 、 Figure 3 and Figure 4 . The air supply mechanism 30 includes a shunt pipe 31. A number of branch pipes 33 are provided on one side of the shunt pipe 31 close to the air blowing assembly 20. The branch pipes 33 are communicated with the airbags 25. A valve body 331 is embedded in the interior of the branch pipes 33. The shunt pipe 31 is connected with an air supply pipe 32 on the side far from the air blowing assembly 20.

[0052] Gas is injected through an external device, such as a blower or other equipment. The air flow enters through the air supply pipe 32 and then enters the interior of the branch pipe 33 through the shunt pipe 31 respectively. Different from the traditional air supply method, here, since the position of the piston plate 231 is in a fixed state, even if the time and speed of the air flow entering are different, it can be ensured that the piston plate 231 and the plug plate 232 can accurately insert into the notch position where the positioning rib 41 of the battery pack 40 is located. When the air pressure reaches the preset threshold value during the internal injection of the air flow, the injection of the gas can be disconnected. The threshold value of the air pressure can be tested according to the designs of different sizes and vehicle models. The air pressure value after a period of time when all the piston plates 231 and the plug plates 232 are pushed to the limit position by the gas is used as the threshold value. This is to ensure that the internal air pressure intensity is sufficient and to avoid the deformation of the airbag 25 caused by the shaking of the piston plate 231 itself when the internal air pressure intensity is insufficient.

[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. Based on this, please refer to Figure 2 And Figure 12 , an outer pipe 321 is threadedly connected to the outer side of one end of the air supply pipe 32 away from the shunt pipe 31. An insertion pipe 3211 is integrally formed on the inner side of the end of the outer pipe 321 away from the air supply pipe 32. The insertion pipe 3211 is inserted into the interior of the air supply pipe 32. An inner pipe 322 is integrally formed on the inner wall of the air supply pipe 32. The outer surface of the insertion pipe 3211 fits the inner wall of the inner pipe 322. A plurality of air grooves 3221 are formed on the inner side wall of the inner pipe 322. A plurality of side grooves two 3212 penetrating to the outside are formed on the inner wall of the insertion pipe 3211. The end of the insertion pipe 3211 inserted into the inner side of the inner pipe 322 is in a sealed state.

[0054] By rotating, two states of connection and dislocation are formed between the air grooves 3221 and the side grooves two 3212. Since the side grooves two 3212 are opened on the side of the insertion pipe 3211 and the end is sealed, when the air grooves 3221 are connected to the side grooves two 3212, the external air flow can enter from the interior of the insertion pipe 3211. When the air grooves 3221 are dislocated from the side grooves two 3212, the connection state is disconnected and a closed state is formed. Only when designing, when the outer pipe 321 and the air supply pipe 32 are completely tightened, the state between the side grooves two 3212 and the air grooves 3221 is in dislocation, so as to ensure the sealing of the structure installation. It is only necessary to insert the air injection pipe into the interior of the insertion pipe 3211 for gas injection. After injecting gas for a period of time, rotate the outer pipe 321 until the entire outer pipe 321 is completely tightened. At this time, the entire device is 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 one side. Alternatively, all valve bodies 331 can be opened to loosen the clamping of all battery packs 40. In addition, the base 11 can be removed, then the support plate 13 on the base 11 can be removed, and then the valve body 331 on the corresponding side can be opened for a period of time and then closed again. In this way, a part of the gas inside the airbag 25 will flow out, but there is still a certain amount of gas inside, so there will be no negative pressure adsorption state on the piston plate 231. In this case, the positioning rod 234 on the insertion plate 232 can be pressed inward alone to disassemble one of the battery packs 40 without affecting the positioning state of other battery packs 40. After disassembly and replacement are completed, gas can be injected again for re-fixation.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed 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.
