Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery device, a positioning tool and an electrical device. Background Art

[0002] In the related art, batteries are usually used in electrical equipment and provide power for the electrical equipment. The electrical equipment will cause the battery to shake during driving or transportation. Excessive battery shaking will have an adverse effect on the performance of the battery. Therefore, how to provide a battery device that can be fixed to the electrical equipment is a technical problem that needs to be solved in battery technology. Utility Model Content

[0003] Based on this, it is necessary to provide a battery device, a positioning tool and an electrical equipment to address the above technical problems. The battery device can be fixed to the electrical equipment through a mounting part, and the manufacturing cost of the battery device can also be reduced.

[0004] According to the first aspect of the present application, a battery device is provided, the battery device includes a box body, an embedded part, a mounting part and an electric body cell, the box body has a accommodating space and a side beam arranged around the accommodating space, and the electric body cell is arranged in the accommodating space. A mounting beam is arranged on the side beam, and a mounting hole is arranged on the mounting beam. The embedded part is at least partially arranged in the mounting hole, and a plug-in hole is arranged on the embedded part, and the mounting hole is arranged around the plug-in hole. At least a part of the mounting part is arranged in the plug-in hole. In the technical solution of the present application, the embedded part can be plugged into the mounting hole, and then at least a part of the mounting part can be plugged into the plug-in hole of the embedded part, so that the battery device can be fixed to the electric device body of the electric device through the mounting part. In addition, the battery cell in the accommodating space of the box body can also provide power to the electric device. Furthermore, since the present application is provided with an embedded part instead of directly fixing the mounting part in the mounting hole, it is advantageous to use a lower-cost punching operation method (compared with laser hole opening, the hole opening cost of the punching operation is lower) to open a larger mounting hole. Therefore, the battery device of the present application is also beneficial to reduce manufacturing costs.

[0005] In one embodiment, at least a portion of the mounting member is welded to the embedded member. The mounting member and the embedded member may be connected by welding to improve the connection stability between the mounting member and the embedded member, thereby more stably fixing the mounting member to the mounting beam, and further more stably fixing the mounting member to the electrical device body of the electrical device.

[0006] In one embodiment, solder is provided between the outer peripheral wall of the mounting part and the inner peripheral wall of the plug hole. By welding the solder between the outer peripheral wall of the mounting part and the inner peripheral wall of the plug hole, the connection stability between the mounting part and the embedded part can be improved, and the mounting part can be fixed to the mounting beam more stably, and the battery device can be fixed to the electrical device body of the electrical device more stably. In addition, the solder is flexible or movable, so that the mounting part is not easy to interfere with the mounting beam after positioning, which increases the adjustment freedom of the mounting part and can compensate for the offset caused by deformation after welding.

[0007] In one embodiment, the solder includes brazing material. The brazing material is flexible or movable, so that the mount is not likely to interfere with the mount beam after positioning, which increases the degree of freedom of adjustment of the mount, can compensate for the offset caused by deformation after welding, and because the brazing deformation is small, it is beneficial to improve the accuracy of the final position of the mount. In addition, the brazing material melts slightly after heating and is connected between the outer peripheral wall of the mount and the inner peripheral wall of the plug hole, so it is not easy for the solder to flow and weld through the mount and other components.

[0008] In one embodiment, the mounting part includes a connected plug-in part and a terminal part, and the plug-in part is plugged into the plug-in hole along the axial direction of the plug-in hole, and the terminal part is blocked outside the hole wall of the plug-in hole. In this way, during the welding operation between the mounting part and the embedded part, the battery device can be inverted so that the terminal part is located at the bottom side of the plug-in part, so that the terminal part is conveniently blocked outside the plug-in hole and receives the solder, so that the solder is disposed between the outer peripheral wall of the mounting part and the inner peripheral wall of the plug-in hole, and before the solder melts, this part of the solder is not easy to overflow or flow out from between the outer peripheral wall of the mounting part and the inner peripheral wall of the plug-in hole, thereby improving the convenience and reliability of the welding operation between the mounting part and the embedded part.

[0009] In one embodiment, the cross section of the end portion perpendicular to the axial direction of the plug hole is circular, and the radial dimension of the end portion is larger than the diameter of the plug hole. It can be understood that the end portion is a cylindrical structure, which is conducive to better limiting the end portion outside the side wall of the plug hole, and then the end portion can also better receive the solder, thereby better improving the convenience and reliability of the welding operation between the mounting part and the embedded part.

[0010] In one embodiment, along the axis direction of the plug hole, the end of the embedded part close to the end head is arranged farther from the end head than the end of the plug hole close to the end head; or, along the axis direction of the plug hole, the end of the plug hole close to the end head is arranged flush with the end of the embedded part close to the end head. It can be understood that the embedded part does not protrude from the end head, and the end head can be well utilized to reduce solder overflow, and the solder can also be used to weld the mounting part to the embedded part, thereby improving the stability of the mounting part, and thereby more stably fixing the mounting part to the electrical equipment body of the electrical equipment.

[0011] In one embodiment, a preset interval is provided between the outer peripheral wall of the mounting part and the inner peripheral wall of the plug hole, and the preset interval is 1mm-3mm. The preset interval is set within a reasonable range, for example, the preset interval is set to 1mm-3mm. In this way, the preset interval can be used to reserve sufficient adjustment space for the mounting part, reduce the occurrence of extrusion deformation or internal stress caused by the mounting part and the mounting beam, and meet the adjustment requirements of welding deformation, thereby facilitating the improvement of the accuracy of the final position of the mounting part.

[0012] In one embodiment, the central axis of the mounting hole coincides with the central axis of the plug hole. The embedded part can be arranged centered relative to the mounting hole, so that at least part of the mounting part can be plugged into the plug hole, and can be arranged roughly centered relative to the mounting hole, thereby facilitating improving the accuracy of the final position of the mounting part.

[0013] In one embodiment, the embedded part is clamped and / or welded to the side wall of the mounting hole, so as to improve the stability and reliability of the embedded part inserted into the mounting hole, thereby facilitating the installation stability of the mounting part.

[0014] In one embodiment, at least two installation holes arranged at intervals are formed through the mounting beam; the battery device includes at least two embedded parts corresponding to the at least two installation holes, and at least two mounting parts corresponding to the at least two embedded parts, the embedded parts are inserted into the corresponding installation holes, and at least part of the mounting parts is inserted into the corresponding insertion holes of the embedded parts. In this way, the mounting stability of the battery device can be improved by using at least two embedded parts and at least two mounting parts.

[0015] In one embodiment, mounting beams are provided on opposite sides of the side beam along the first direction; at least two mounting holes on the same mounting beam are arranged at intervals along the second direction; wherein the first direction and the second direction intersect each other and are both perpendicular to the bottom surface of the box body. Thus, since mounting beams are provided on opposite sides of the side beam along the first direction, the mounting parts on the mounting beams on both sides can be respectively connected to the electrical equipment body of the electrical equipment, thereby facilitating the improvement of the installation stability and balance of the battery device.

[0016] In one embodiment, the mounting hole is arranged through the mounting beam, so that the embedded component can be installed on the side wall of the mounting hole.

[0017] According to the second aspect of the present application, a positioning tool is provided. The positioning tool is applied to the battery device of any of the above embodiments. The positioning tool includes a positioning shaft. The positioning shaft is passed through the mounting part along the axial direction of the mounting hole and is connected to the inner wall of the mounting part. In this way, after selecting the installation position of the mounting part in the plug-in hole, the mounting part can be fixed by the positioning tool so that the mounting part is positioned at the installation position. Then, solder is loaded into the gap between the embedded part and the mounting part. Then, the solder is melted and welded between the embedded part and the mounting part by welding. Induction brazing can be used to weld parts of the mounting part. In this way, the positioning tool can be used to improve the accuracy of the final position of the mounting part.

[0018] According to a third aspect of the present application, there is provided an electrical device comprising the battery device of any one of the above embodiments.

Figure 4 Shows Figure 3AA cross-sectional diagram of Figure 5 Shows Figure 4 A partial enlarged schematic diagram of .

[0044] Please refer to Figure 2-Figure 5 According to the first aspect of the present application, an embodiment of the present application provides a battery device 10, including a box assembly and an electric body cell, the box assembly includes a box 100, an embedded part 200 and a mounting part 300, the box 100 has a accommodating space R and a side beam 110 arranged around the accommodating space R, and the electric body cell is arranged in the accommodating space R. A mounting beam 120 is arranged on the side beam 110 of the box 100, and a mounting hole K1 is arranged on the mounting beam 120. The box 100 is used to accommodate battery cells to prevent liquid or other foreign matter from affecting the charging or discharging of the battery cells. The box 100 can be a simple three-dimensional structure such as a single rectangular parallelepiped or a cylinder or a sphere, or it can be a complex three-dimensional structure composed of simple three-dimensional structures such as rectangular parallelepiped or a cylinder or a sphere, and the embodiment of the present application is not limited to this.

[0045] The accommodation space R refers to a space provided in the box body 100 and used to accommodate a battery cell.

[0046] The battery device 10 may further include a cover body, which is used to cover the box body 100 and to close the accommodation space R to protect the battery cells in the accommodation space R.

[0047] The side beam 110 refers to a portion disposed around the accommodation space R on the box body 100 .

[0048] The mounting beam 120 refers to a beam disposed on the side beam 110 and used to connect the main body of the electrical equipment.

[0049] The mounting hole K1 refers to a hole penetrating through the mounting beam 120 and is used to mount the embedded component 200 .

[0050] The embedded component 200 is at least partially disposed in the mounting hole K1 , and an inserting hole K2 is disposed on the embedded component 200 . The mounting hole K1 is disposed around the inserting hole K2 , and at least a portion of the mounting component 300 is disposed in the inserting hole K2 .

[0051] It can be understood that at least a portion of the embedded component 200 is inserted into the installation hole K1, and at least a portion of the mounting component 300 is inserted into the insertion hole K2.

[0052] The embedded component 200 is a component used for being inserted into the mounting hole K1 and having an inserting hole K2 . The embedded component 200 may be made of metal, such as steel.

[0053] The inserting hole K2 refers to a hole provided on the embedding component 200 and is located inside the mounting hole K1 .

[0054] The mounting member 300 refers to a component that is used to be at least partially inserted into the insertion hole K2 and can be mounted on the main body of the electrical equipment.

[0055] “At least part of the mounting member 300 is inserted into the insertion hole K2” may mean that part of the mounting member 300 is inserted into the insertion hole K2, or the mounting member 300 is completely inserted into the insertion hole K2, which is not specifically limited here.

[0056] In the technical solution of the present application, the embedded part 200 can be inserted into the installation hole K1, and then at least part of the mounting part 300 can be inserted into the insertion hole K2 of the embedded part 200, so that the battery device 10 can be fixed to the electrical device body of the electrical device through the mounting part 300, which is beneficial to improve the installation stability and service life of the battery device 10 to a certain extent. In addition, the battery monomer in the accommodating space R of the box 100 can also provide power for the electrical device. And because the present application is provided with an embedded part 200 instead of directly fixing the mounting part 300 in the installation hole K1, it is beneficial to use a lower-cost punching operation method (compared with laser hole opening, the hole opening cost of the punching operation is lower) to open a larger installation hole K1, so the battery device 10 of the present application is also beneficial to reduce manufacturing costs.

[0057] In some embodiments, the mounting hole K1 is disposed through the mounting beam 120 .

[0058] In this way, the embedded component 200 is conveniently installed on the side wall of the installation hole K1.

[0059] In some embodiments, at least a portion of the mounting component 300 is connected to the embedding component 200 by welding.

[0060] It is possible that a part of the mounting component 300 is connected to the embedded component 200 by welding; or it is possible that the mounting component 300 is connected to the embedded component 200 by welding; there is no specific limitation here.

[0061] The mounting member 300 can be connected to the embedded member 200 by welding to improve the connection stability between the mounting member 300 and the embedded member 200, so that the mounting member 300 can be more stably fixed to the mounting beam 120, and the mounting member 300 can be more stably fixed to the electrical equipment body of the electrical equipment.

[0062] In some embodiments, solder 400 is disposed between the outer peripheral wall of the mounting component 300 and the inner peripheral wall of the plug hole K2 .

[0063] The solder 400 may be a welding rod, a welding wire or a solder, which is not particularly limited herein.

[0064] Solder 400 may be provided between the outer peripheral wall of the mounting part 300 and the inner peripheral wall of the insertion hole K2. By welding the solder 400 between the outer peripheral wall of the mounting part 300 and the inner peripheral wall of the insertion hole K2, the connection stability between the mounting part 300 and the embedded part 200 may be improved, and the mounting part 300 may be fixed to the mounting beam 120 more stably, and the battery device 10 may be fixed to the electrical device body of the electrical device more stably. In addition, the solder 400 is flexible or movable, so that the mounting part 300 is not easy to interfere with the mounting beam 120 after being positioned, and the adjustment freedom of the mounting part 300 is increased, and the offset formed by the deformation after welding can be compensated.

[0065] In some embodiments, the solder 400 includes brazing material.

[0066] The solder refers to a welding material used to weld the workpieces to be welded and to form a weld during the brazing process. The solder can be welded at least between the outer peripheral wall of the mounting member 300 and the inner peripheral wall of the insertion hole K2 by induction brazing.

[0067] The solder is flexible or movable, so that the mounting part 300 is not likely to interfere with the mounting beam 120 after being positioned, which increases the adjustment freedom of the mounting part 300, and can compensate for the offset caused by the deformation after welding. Moreover, since the soldering deformation is small, it is beneficial to improve the accuracy of the final position of the mounting part 300. In addition, the solder is slightly melted after heating and connected between the outer peripheral wall of the mounting part 300 and the inner peripheral wall of the plug hole K2, and it is not easy for the solder 400 to flow and weld through the mounting part 300 and other parts.

[0068] In some embodiments, the mounting member 300 includes a connected plug-in portion 310 and an end portion 320 . Along the axial direction of the plug-in hole K2 , the plug-in portion 310 is plugged into the plug-in hole K2 , and the end portion 320 is blocked outside the hole wall of the plug-in hole K2 .

[0069] The plug-in portion 310 refers to a portion of the mounting component 300 located inside the plug-in hole K2 , and the end portion 320 refers to a portion of the mounting component 300 located outside the plug-in hole K2 and blocked by the hole wall of the plug-in hole K2 .

[0070] In this way, during the welding operation between the mounting component 300 and the embedded component 200, the battery device 10 can be inverted so that the end portion 320 is located on the bottom side of the plug-in portion 310, so that the end portion 320 is conveniently blocked outside the plug-in hole K2 and receives the solder 400, so that the solder 400 is disposed between the outer peripheral wall of the mounting component 300 and the inner peripheral wall of the plug-in hole K2, and before the solder 400 melts, this part of the solder 400 is not easy to overflow or flow out from between the outer peripheral wall of the mounting component 300 and the inner peripheral wall of the plug-in hole K2, thereby improving the convenience and reliability of the welding operation between the mounting component 300 and the embedded component 200.

[0071] In some embodiments, the cross-section of the end portion 320 perpendicular to the axial direction of the plug hole K2 is circular, and the radial dimension of the end portion 320 is larger than the aperture of the plug hole K2.

[0072] It can be understood that the end portion 320 is a cylindrical structure, which is beneficial for better limiting the end portion 320 outside the side wall of the plug hole K2, and thus the end portion 320 can also better receive the solder 400, thereby better improving the convenience and reliability of the welding operation between the mounting part 300 and the embedded part 200.

[0073] In some embodiments, along the axial direction of the inserting hole K2 , compared with the end of the inserting hole K2 close to the end portion 320 , the end of the inserting member 200 close to the end portion 320 is disposed farther away from the end portion 320 .

[0074] It can be understood that the end of the insert 200 close to the end head 320 does not protrude from the end of the plug hole K2 close to the end head 320, and along the axial direction of the plug hole K2, the insert 200 is at a certain distance from the end head 320, so that a part of the solder 400 can be arranged between the outer peripheral wall of the mounting part 300 and the inner peripheral wall of the plug hole K2, and the other part of the solder 400 contacts the side wall of the mounting hole K1 through the gap between the end of the insert 200 close to the end head 320 and the end head 320 (which can be combined with Figure 6 In this way, the end portion 320 can be used to reduce the overflow of the solder 400, and the solder 400 can be used to weld the mounting part 300 to the embedding part 200 and the side wall of the mounting hole K1 respectively, thereby improving the installation stability of the mounting part 300, and furthermore, the battery device 10 can be more stably fixed to the electrical equipment body of the electrical equipment through the mounting part 300.

[0075] In some other embodiments, along the axial direction of the inserting hole K2 , one end of the inserting hole K2 close to the end portion 320 is flush with one end of the inserting member 200 close to the end portion 320 .

[0076] In this way, the end portion 320 can be well utilized to reduce the overflow of the solder 400, and the solder 400 can also be used to weld the mounting part 300 to the embedded part 200, thereby improving the stability of the mounting part 300, and furthermore, the mounting part 300 can be more stably fixed to the electrical equipment body of the electrical equipment.

[0077] In other embodiments, a preset interval is provided between the outer circumferential wall of the mounting component 300 and the inner circumferential wall of the plug hole K2, and the preset interval is 1 mm-3 mm, wherein the preset interval is J, and J is 1 mm-3 mm.

[0078] Illustratively, J is 1 mm, 2 mm or 3 mm.

[0079] The preset interval is set within a reasonable range, for example, the preset interval is set to 1mm-3mm. In this way, the preset interval can be used to reserve sufficient adjustment space for the mounting part 300, reduce the occurrence of hard-to-hard extrusion deformation or internal stress between the mounting part 300 and the mounting beam 120, and meet the adjustment requirements of welding deformation, thereby facilitating the improvement of the accuracy of the final position of the mounting part 300. In addition, the gap between the outer peripheral wall of the mounting part 300 and the inner peripheral wall of the plug hole K2 is small, so that the mounting part 300 and the embedded part 200 are matched with a small gap, and it is not easy for the solder 400 to flow and weld through the mounting part 300 and other parts, which is also conducive to improving the welding yield between the mounting part 300 and the embedded part 200.

[0080] In some embodiments, the central axis of the mounting hole K1 and the central axis of the plugging hole K2 coincide with each other.

[0081] Thus, the embedding member 200 is centered relative to the mounting hole K1, which facilitates at least a portion of the mounting member 300 to be inserted into the insertion hole K2, and can be roughly centered relative to the mounting hole K1, thereby facilitating improving the accuracy of the final position of the mounting member 300.

[0082] In some embodiments, the embedded component 200 is snap-fitted and / or welded to the side wall of the mounting hole K1 .

[0083] The embedded part 200 adapted to the mounting hole K1 can be manufactured as required, and then the embedded part 200 is clamped on the side wall of the mounting hole K1. The embedded part 200 can also be welded to the side wall of the mounting hole K1 by welding. Of course, the present application is not limited to this, and the embedded part 200 can also be clamped on the side wall of the mounting hole K1 first, and then the embedded part 200 and the side wall of the mounting hole K1 are welded.

[0084] In this way, the stability and reliability of the insertion of the embedding component 200 into the mounting hole K1 can be improved, thereby facilitating the improvement of the installation stability of the mounting component 300 .

[0085] In some embodiments, please combine Figure 3 and Figure 7 At least two installation holes K1 arranged at intervals are formed through the mounting beam 120, and the battery device 10 includes at least two embedded components 200 corresponding to the at least two installation holes K1, and at least two mounting components 300 corresponding to the at least two embedded components 200. The embedded components 200 are inserted into the corresponding installation holes K1, and at least a portion of the mounting components 300 is inserted into the corresponding insertion holes K2 of the embedded components 200.

[0086] In this way, at least two embedding members 200 and at least two mounting members 300 can be used to improve the mounting stability of the battery device 10 .

[0087] In some embodiments, mounting beams 120 are respectively disposed on opposite sides of the side beam 110 along the first direction F1, and at least two mounting holes K1 on the same mounting beam 120 are arranged at intervals along the second direction F2. The first direction F1 and the second direction F2 intersect each other and are both perpendicular to the bottom surface of the box body 100.

[0088] In some embodiments, the first direction F1 and the second direction F2 are perpendicular to each other and are perpendicular to the bottom surface of the box 100. For example, the first direction F1 is parallel to one of the length direction and the width direction of the box 100, and the second direction F2 is parallel to the other of the length direction and the width direction of the box 100.

[0089] Thus, since mounting beams 120 are respectively provided on opposite sides of the side beam 110 along the first direction F1, the mounting members 300 on the mounting beams 120 on both sides can be respectively connected to the electrical equipment body of the electrical equipment, thereby facilitating the installation stability and balance of the battery device 10.

[0090] When the battery device 10 of the present application is manufactured, the solder 400 can be loaded into the gap between the embedding part 200 and the mounting part 300, and then the solder 400 is melted and welded between the embedding part 200 and the mounting part 300 by welding. This is beneficial to improve the installation stability of the mounting part 300, and then the battery device 10 can be more stably fixed to the electrical device body of the electrical device through the mounting part 300.

[0091] According to the second aspect of the present application, the present application provides a positioning tool, which is applied to the battery device 10 of any of the above-mentioned embodiments. The positioning tool (not shown in the figure) includes a positioning shaft (not shown in the figure). The positioning shaft is penetrated into the mounting component 300 along the axial direction of the mounting hole K1 and is connected to the inner side wall of the mounting component 300.

[0092] Specifically, a connecting hole K3 is formed through the mounting component 300 , and the positioning shaft passes through the connecting hole K3 and is connected to the inner wall of the mounting component 300 .

[0093] In this way, after selecting the installation position of the mounting member 300 in the plug hole K2, the mounting member 300 can be fixed by the positioning tool to position the mounting member 300 at the installation position, and then the solder 400 is loaded into the gap between the embedded member 200 and the mounting member 300, and then the solder 400 is melted and welded between the embedded member 200 and the mounting member 300 by welding. Induction brazing can be used to weld a part of the mounting member 300. In this way, the positioning tool can be used to improve the accuracy of the final position of the mounting member 300.

[0094] According to a third aspect of the present application, the present application provides an electrical device, comprising the battery device 10 of any one of the above embodiments.

[0095] In some embodiments, the electrical equipment also includes an electrical equipment body, a connection hole K3 is penetrated through the mounting component 300, the plug-in hole K2 is arranged around the connection hole K3, the battery device 10 also includes a connector adapted to the connection hole K3, and the mounting component 300 is connected to the electrical equipment body through the connector.

[0096] The electrical device may be a vehicle, the electrical device body may include a frame, and the mounting component 300 may be connected to the frame via a connecting component.

[0097] In this way, the battery device 10 can be fixed to the electrical equipment body by using the mounting member 300 and the connecting member, thereby improving the installation stability of the battery device 10 and helping to increase the service life of the battery device 10 to a certain extent.

[0098] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
