[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0029] like Figure 1As shown, the battery holder 1 includes a frame 100, and the frame 100 is provided with a battery connection portion 10 and a device connection portion 20. Specifically, in the present embodiment, the frame 100 is a plate-like structure as a whole, and in order to ensure the structural strength of the frame 100, the frame 100 is made of a metal material, for example, the frame 100 can be a steel plate, an iron plate, an alloy plate, etc. The overall shape of the frame 100 can be flexibly designed according to actual conditions. For example, in the scheme shown in the figure, the frame 100 is a rectangular plate with weight-reducing notches 40 on both sides, which is not only simple in structure and easy to cast, but also can prevent the frame 100 from being too heavy.

[0030] The frame 100 is provided with a battery connection portion 10, and the battery connection portion 10 is used to connect with the battery pack 41, so that the battery pack 41 can be fixed on the frame 100. It should be noted that the fixing method between the battery connection portion 10 and the battery pack 41 can be flexibly designed as needed, as long as the battery pack 41 can be stably fixed on the frame 100. For example, Figure 4 and Figure 5 In the illustrated embodiment, the battery connection portion 10 includes a plurality of fixing through holes 101, and a plurality of threaded connection holes 412 are correspondingly provided on the battery pack 41, and then a plurality of battery bolts 42 are passed through the plurality of fixing through holes 101 one by one and are screwed into the plurality of threaded connection holes 412 one by one, thereby achieving a fixed connection between the battery pack 41 and the frame 100. For another example, in some other embodiments, a plurality of buckles may be provided on the battery pack 41, and the battery connection portion 10 includes a plurality of snap holes, and the buckles may be correspondingly snapped into the snap holes, and then the battery pack 41 may be fixed to the frame 100 by snapping. For another example, the battery connection portion 10 may also be bonded and fixed to the battery pack 41 by adhesive. In short, the fixing method between the battery connection portion 10 and the battery pack 41 may be flexibly selected according to actual needs.

[0031] In addition, with respect to the solution mentioned above that “the battery connection portion 10 is fixedly connected to the battery pack 41 through the battery bolt 42”, as Figure 5 As shown, in order to prevent external water vapor from entering the battery pack 41 through the threaded connection hole 412, a plurality of rivet nuts 411 are further installed on the battery pack 41, each rivet nut 411 is formed with a threaded connection hole 412, and the threaded connection hole 412 is a blind hole, so that the threaded connection hole 412 will not be connected to the interior of the battery pack 41, thereby preventing external water vapor from entering the battery pack 41 through the threaded connection hole 412.

[0032] It should also be noted that there may be multiple battery connection parts 10, so that the battery holder 1 can be connected to multiple battery packs 41 at the same time, thereby reducing the number of battery holders 1 used, reducing costs and weight. Figure 5As shown, in this embodiment, the battery connection part 10 includes an upper connection part 11 and a lower connection part 12, and the upper connection part 11 and the lower connection part 12 are respectively used to connect a battery pack 41, that is, one battery holder 1 is connected to two battery packs 41 at the same time, and the two battery packs 41 are arranged at intervals along the upper and lower directions to ensure the safety of electricity use. Of course, in other embodiments, the battery connection parts 10 can also be provided with three, four, five, etc., so that the battery holder 1 can be connected to a larger number of battery packs 41 at the same time, and the specific number of battery connection parts 10 can be flexibly designed according to actual conditions.

[0033] like Figure 1 As shown, the battery holder 1 is also provided with a device connection portion 20, which is used to connect to an electric device 5 (such as an electric car, a charging pile, etc.). Figure 1 and Figure 6 The device connecting part 20 includes a first connecting part 21 and a second connecting part 22. The first connecting part 21 is used to connect to the first fixing part 52 on the electric device 5, and the second connecting part 22 is used to connect to the second fixing part 53 on the electric device 5. That is, the battery holder 1 is fixed to the electric device 5 through two fixing points, so that the connection strength between the battery holder 1 and the electric device 5 can be ensured.

[0034] Among them, you can refer to Figure 7 In one embodiment, the first connecting portion 21 is provided with a screw hole 211, the screw hole 211 has an internal thread, the electric device 5 is provided with a mounting bracket 51, and the first fixing portion 52 and the second fixing portion 53 are both provided on the mounting bracket 51. The first fixing portion 52 includes a first through hole 521 and a first bolt 522 inserted into the first through hole 521. Fig. 9 As shown, during assembly, the first bolt 522 passes through the first through hole 521 and is screwed into the screw hole 211. Of course, in other embodiments, the first connecting portion 21 may also be provided with a buckle, and the first fixing portion 52 is correspondingly provided with a buckle hole, so that the first connecting portion 21 and the first fixing portion 52 are connected by a buckle.

[0035] It should be noted that, for the solution of "the first connection portion 21 is provided with a screw hole 211", since the screw hole 211 itself needs to have a certain depth to ensure stable connection, in this embodiment, Figure 1 As shown, the first connection portion 21 is provided with a connection protrusion 212, and the connection protrusion 212 is provided with the screw hole 211, which can ensure that the screw hole 211 has a sufficient depth and avoid the situation where the entire frame 100 needs to be designed with a larger thickness.

[0036] Can be combined Figure 1 and Figure 7In this embodiment, the second connecting portion 22 is provided with a connecting hole 221, and the connecting hole 221 is used for the second fixing portion 53 to pass through and connect to the second connecting portion 22, and the connecting hole 221 is also used for clearance fit with the second fixing portion 53, so that the relative position between the connecting hole 221 and the second fixing portion 53 is adjustable. Specifically, Figure 7 As shown, the second fixing portion 53 includes a second through hole 531, a second bolt 532 and a second nut 533, wherein the second bolt 532 includes a fixing head 5321 and a fixing rod 5322, the fixing head 5321 is located at a side of the connecting through hole 221 away from the mounting bracket 51, the fixing rod 5322 passes through the connecting through hole 221 and the second through hole 531 in sequence from the fixing head 5321, and the nut 533 is located at a side of the mounting bracket 51 away from the fixing head 5321 (i.e. Figure 8 The nut 533 is screwed on the fixing rod 5322. It can be understood that the nut 533 can not only limit the second bolt 532 from being separated from the mounting bracket 51, but also pull the second bolt 532 toward the operating side 512 when tightening, and at this time, the fixing head 5321 can not only limit the frame 100 from being away from the mounting bracket 51, but also generate friction with the frame 100, thereby forming a certain support for the frame 100.

[0037] Of course, in addition to pulling the second bolt 532 toward the operating side 512 through the nut 533, an eccentric component (such as an eccentric wheel) can be installed on the fixed rod 5322, and the fixed rod 5322 and the fixed head 5321 can be pulled toward the operating side 512 when the eccentric component rotates to a certain angle. In this way, the connection between the second fixed portion 53 and the second connecting portion 22 can also be achieved.

[0038] It is also understandable that, because errors are inevitable in the production process, in some cases, the distance between the first connection part 21 and the second connection part 22 may not be equal to the distance between the first fixing part 52 and the second fixing part 53, resulting in "when the first connection part 21 and the first fixing part 52 are accurately aligned, the second connection part 22 and the second fixing part 53 are not accurately aligned", or "when the second connection part 22 and the second fixing part 53 are accurately aligned, the first connection part 21 and the first fixing part 52 are not accurately aligned".

[0039] Therefore, in this embodiment, the connecting via 221 is also configured to be able to be gap-matched with the second fixing portion 53, so that the relative position between the connecting via 221 and the second fixing portion 53 is adjustable. Figure 7, taking the example that the second fixing portion 53 includes a fixing head portion 5321 and a fixing rod portion 5322, and the fixing rod portion 5322 is cylindrical, in this case, the connecting via 221 can be designed as a waist-shaped hole, and the length of the connecting via 221 is greater than the outer diameter of the fixing rod portion 5322, and then the relative position between the connecting via 221 and the fixing rod portion 5322 at least in the length direction of the connecting via 221 is adjustable. Alternatively, the connecting via 221 can be a circular hole with an opening area greater than the fixing rod portion 5322 and smaller than the fixing head portion 5321, in which case the connecting via 221 and the fixing rod portion 5322 can move relative to each other in any direction, that is, the relative position between the connecting via 221 and the second fixing portion 53 in any direction is adjustable.

[0040] It should be noted that the clearance direction of the connecting hole 221 and the fixing rod 5322 when the clearance fits can be set according to the actual situation. For example, in one embodiment, Figure 3 As shown, the connecting via 221 is a long hole with a length direction and a width direction, for example, the connecting via 221 is a rectangular hole, a waist-shaped hole, or other long holes with a length-to-width ratio greater than 1, and the first connecting portion 21 and the second connecting portion 22 are arranged at intervals along the length direction of the connecting via 221, and the connecting via 221 is at least used to be gap-matched with the second fixing portion 53 in its length direction. Specifically, taking the first connecting portion 21 and the second connecting portion 22 as an example of being spaced apart in the up-down direction, according to production experience, the error generated in the up-down direction is usually larger, and the errors generated in other directions are usually smaller, so by making the connecting via 221 at least used to be gap-matched with the second fixing portion 53 in its length direction, the error in actual production can be compensated more specifically, and the connecting via 221 is prevented from being opened too large to affect the connection strength and structural strength.

[0041] In addition, the size of the gap between the connecting via 221 and the fixed rod 5322 when they are matched can also be set according to actual conditions. For example, during production, the error range between the two fixed points in the up and down directions is mostly within 5 mm. Then the gap between the connecting via 221 and the fixed rod 5322 in the up and down directions is at least not less than 5 mm, and can be specifically 5 mm, 5.5 mm, 6 mm, 6.5 mm, etc., to ensure that there is sufficient adjustment space.

[0042] It can be understood that in this embodiment, the connection through hole 221 on the battery holder 1 is set to be able to loosely fit with the second fixing part 53 on the electric device 5, so that the relative position between the connection through hole 221 and the second fixing part 53 is adjustable, that is, when the entire battery holder 1 moves relative to the second fixing part 53, the second fixing part 53 can still correspond to the second connection through hole 221 and connect with the second connection part 22. In this way, when the first connection part 21 and the first fixing part 52 are not aligned, the first connection part 21 and the first fixing part 52 can be accurately aligned by moving the entire battery holder 1, and it is ensured that the second connection part 22 and the second fixing part 53 will not be misaligned due to the movement of the battery holder 1, thereby ensuring that the battery holder 1 can be smoothly installed on the electric device 5 with the battery pack 41, thereby solving the technical problem that the battery holder 1 is inconvenient to install due to the spacing error between the fixing points.

[0043] Of course, in order to solve the technical problem that the battery holder 1 is inconvenient to install due to the spacing error between the fixing points, in addition to the solution described above, in another embodiment, a connecting through hole (not shown) can also be provided on the first connecting portion 21, and the connecting through hole is used for the first fixing portion 52 to pass through and connect to the first connecting portion 21, and the connecting through hole is also used to match the clearance with the first fixing portion 52, so that the relative position between the connecting through hole and the first fixing portion 52 is adjustable. Specifically, the size, shape, and matching between the connecting through hole and the first fixing portion 52 can be designed with reference to the connecting through hole 221, and the extending connecting through hole can be completely designed according to the connecting through hole 221, so the connecting through hole will not be introduced in detail here, and the specifics can refer to the introduction of the connecting through hole 221 in this specification.

[0044] It can be understood that in this embodiment, a connecting through hole is provided on the first connecting portion 21, and the connecting through hole is also configured to be able to loosely fit with the first fixing portion 52 on the electric device 5, so that the relative position between the connecting through hole and the first fixing portion 52 is adjustable, and thus, by adjusting the position of the first fixing portion 52 in the connecting through hole, the effect of "the first connecting portion 21 is accurately aligned with the first fixing portion 52, and the second connecting portion 22 is also accurately aligned with the second fixing portion 53" can be achieved, which provides double insurance for solving the technical problem that "the battery holder 1 is inconvenient to install due to the spacing error between the fixing points".

[0045] In one embodiment, if Figure 3 As shown, a mounting opening 2211 is provided on one side of the connecting via hole 221 away from the first fixing portion 52, and the mounting opening 2211 is used for the second fixing portion 53 to enter and exit the connecting via hole 221 along the length direction of the connecting via hole 221. Figure 7 or Figure 8As shown, the second fixing portion 53 includes a second through hole 531, a second bolt 532 and a nut 533 provided on the mounting bracket 51. The second bolt 532 is pre-installed in the second through hole 531, and the fixing head 5321 of the second bolt 532 is located at the connection side 511 of the mounting bracket 51, and the fixing rod 5322 extends from the fixing head 5321 to the operation side 512 of the mounting bracket 51, and the nut 533 is screwed on the operation side 512 of the mounting bracket 51 and screwed on the fixing rod 5322. During assembly, the battery bracket 1 moves from top to bottom with the battery pack 41 until the fixing rod 5322 passes through the mounting opening 2211 and enters the connection through hole 221, and the first connecting portion 21 and the first fixing portion 52 are accurately aligned.

[0046] That is to say, in this embodiment, the moving direction of the battery holder 1 during installation and the adjustment direction during error compensation are the same direction, so that the assembler can adjust the position of the battery holder 1 while assembling, which is conducive to improving assembly efficiency.

[0047] In one embodiment, if Figure 3 As shown, the connecting hole 221 includes a connecting hole section 2212 and a guide hole section 2213 that are interconnected along the length direction thereof, the guide hole section 2213 is located between the connecting hole section 2212 and the mounting opening 2211, and the guide hole section 2213 has two guide side walls 2214 that are opposite to each other along the width direction of the connecting hole 221, and each guide side wall 2214 gradually tilts toward the side where the other guide side wall 2214 is located while extending from the mounting opening 2211 to the connecting hole section 2212. Therefore, the guide side wall 2214 can guide the fixing rod portion 5322 when the fixing rod portion 5322 enters, so as to ensure that the fixing rod portion 5322 can enter the connecting hole section 2212 more smoothly, thereby improving the assembly efficiency.

[0048] In one embodiment, if Figure 7 As shown, the second fixing portion 53 includes a fixing rod portion 5322 and a fixing head portion 5321. Figure 1 and Figure 2 As shown, the second connecting portion 22 includes a connecting boss 222, which is formed by bending a part of the plate body of the frame 100, and a limiting space 2221 is provided in the connecting boss 222, and a connecting through hole 221 is provided on the connecting boss 222 and passes through the limiting space 2221; the mounting opening 2211 is used for allowing the fixing rod portion 5322 to enter and exit the connecting through hole 221 along the length direction of the connecting through hole 221, and also for allowing the fixing head portion 5321 to enter and exit the limiting space 2221 along the length direction of the connecting through hole 221, and the limiting space 2221 is used to accommodate the fixing head portion 5321, so as to limit the connecting boss 222 from detaching from the electric device 5 along the axial direction of the fixing rod portion 5322 through the fixing head portion 5321.

[0049] Specifically, please refer to Figure 8 The second fixing portion 53 includes a second through hole 531, a second bolt 532 and a nut 533 provided on the mounting bracket 51. The second bolt 532 is pre-installed in the second through hole 531, and the fixing head 5321 of the second bolt 532 is located on the connecting side 511 of the mounting bracket 51. The fixing rod 5322 extends from the fixing head 5321 to the operating side 512 of the mounting bracket 51. The nut 533 is screwed on the operating side 512 of the mounting bracket 51 and is screwed on the fixing rod 5322. During assembly, the battery bracket 1 moves from top to bottom with the battery pack 41, and in the process of downward movement, the fixing rod 5322 will enter the connecting through hole 221 through the mounting opening 2211, and the fixing head 5321 will enter the limiting space 2221 through the mounting opening 2211. Fig. 9 As shown, when the fixed head 5321 is located in the limiting space 2221 , the fixed head 5321 can limit the connecting boss 222 from detaching from the mounting bracket 51 along the axial direction of the fixed rod 5322 , thereby ensuring that the battery bracket 1 is stably mounted on the mounting bracket 51 .

[0050] In one embodiment, if Figure 1 or Figure 3 As shown, the battery connection part 10 includes an upper connection part 11 and a lower connection part 12 that are spaced apart. The upper connection part 11 and the lower connection part 12 are respectively used for connecting one battery pack 41, that is, one battery holder 1 is used to install two battery packs 41 at the same time, and in order to ensure the safety of electricity use, the two battery packs 41 are spaced apart from each other. At this time, in addition to connecting the two battery packs 41, the frame 100 also needs to support the weight of the battery pack 41 connected to the upper connection part 11. Therefore, in order to ensure that the frame 100 has sufficient supporting strength, in this embodiment, a reinforcing rib 30 is further provided on the frame 100, and the reinforcing rib 30 at least partially extends along the spacing direction of the upper connection part 11 and the lower connection part 12, thereby strengthening the structural strength of the frame 100 in the up and down directions, ensuring that the frame 100 is not easily bent and deformed, so that the two battery packs 41 are stably spaced apart.

[0051] In one embodiment, if Figure 1 or Figure 3As shown, the first connection part 21 and the second connection part 22 are arranged between the upper connection part 11 and the lower connection part 12, and the first connection part 21 is closer to the upper connection part 11 than the second connection part 22. The reinforcing rib 30 includes a connecting reinforcing rib 31, and the connecting reinforcing rib 31 is connected between the first connection part 21 and the second connection part 22. It can be understood that the battery pack 41 connected to the upper connection part 11 is mainly supported by the frame 100, and the frame 100 is fixed to the mounting bracket 51 through the first connection part 21 and the second connection part 22, so the first connection part 21 and the second connection part 22 are the main force points on the frame 100. Therefore, by making the reinforcing rib 30 include a connecting reinforcing rib 31, and the connecting reinforcing rib 31 is connected between the first connection part 21 and the second connection part 22, the supporting strength of the first connection part 21 and the second connection part 22 can be improved, so as to ensure that the battery pack 41 is installed on the mounting bracket 51 more stably.

[0052] It should be noted that, because the connecting hole 221 on the second connecting portion 22 is clearance-matched with the second fixing portion 53, there is a situation where the fixing rod portion 5322 and the top of the connecting hole 221 are spaced apart from each other (see Fig. 9 ), at this time, the second connection part 22 has a smaller support force on the frame 100, and most of the pressure will be concentrated on the first connection part 21. Therefore, in one embodiment, if Figure 1 or Figure 3 As shown, the reinforcing ribs 30 also include a plurality of reinforcing ribs 32, and the plurality of reinforcing ribs 32 all extend from the first connecting portion 21 to the lower connecting portion 12, and the plurality of reinforcing ribs 32 are symmetrically arranged about the connecting reinforcing ribs 31. In this way, the pressure of the first connecting portion 21 can be shared by the plurality of reinforcing ribs 32, and the pressure on the first connecting portion 21 can be evenly distributed to each reinforcing rib 32, thereby preventing the first connecting portion 21 from being bent and deformed due to excessive force, thereby ensuring a stable spacing between the two battery packs 41.

[0055] Specifically, in one embodiment, Fig. 9 As shown, the mounting bracket 51 has a relative connecting side 511 and an operating side 512, and the power supply assembly 4 composed of a battery pack 41 and a battery bracket 1 is located on the connecting side 511, wherein the first connecting portion 21 on the battery bracket 1 is provided with a screw hole 211, and the first fixing portion 52 includes a first through hole 521 and a first bolt 522, and the first bolt 522 includes a bolt head 5221 and a threaded rod 5222, the bolt head 5221 is located on the operating side 512, and the threaded rod 5222 passes through the first through hole 521 to the connecting side 511 and is connected to the screw hole 211.

[0056] like Fig. 9 As shown, the second fixing portion 53 includes a second through hole 531, a second bolt 532 and a nut 533. The second bolt 532 includes a fixing rod 5322 and a fixing head 5321. The fixing head 5321 is located on the connecting side 511 and is limited in the limiting space 2221 of the second connecting portion 22. The fixing rod 5322 passes through the connecting through hole 221 and the second through hole 531 in sequence from the fixing head 5321. The nut 533 is located on the operating side 512 and is screwed onto the fixing rod 5322.

[0057] Please combine Figure 8 and Fig. 9 During assembly, the second bolt 532 can be pre-installed on the mounting bracket 51 through the nut 533, and then the battery bracket 1 with the battery pack 41 installed can be moved from top to bottom corresponding to the second bolt 532, until the fixing rod 5322 of the second bolt 532 enters the connecting through hole 221 and the fixing head 5321 enters the limiting space 2221, and then the position of the battery bracket 1 is adjusted up and down until the screw hole 211 is accurately aligned with the first through hole 521, and then the first bolt 522 is passed through the first through hole 521 and connected to the screw hole 211, and the nut 533 on the second bolt 532 is tightened.
