[0062] The battery pack is used to provide power for the electrical equipment, and is an important power source. At present, after the existing battery pack is inserted into the electrical equipment, a cover needs to be added to the electrical equipment in order to fix the battery pack to the electrical equipment.

[0063] However, the existing battery pack is inconvenient to take off from the electrical equipment, and needs to be first taken off from the electrical equipment, and then taken out from the electrical equipment by force, which is very inconvenient to operate.

[0064] Based on the above technical problems, the present application provides a power supply assembly to solve the problem of inconvenient taking and placing of the existing battery pack 20 of the electrical equipment.

[0065] As shown in Figures 1-14 , the overall design, the power supply assembly includes a mounting seat 10, a battery pack 20 and a locking member 30. Among them, the mounting seat 10 is provided with a containing cavity 11, and the containing cavity 11 has an opening at one end along the first direction a. The battery pack 20 has a shell 21 matched with the containing cavity 11, and a limiting guide part provided on the surface of the shell 21. The locking member 30 is rotatably arranged on the mounting seat 10, and the locking member 30 has a locking part 31 matched with the limiting guide part. The elastic return member 40 is arranged between the mounting seat 10 and the locking member 30, and the elastic return member 40 is used to drive the locking member 30 to rotate relative to the mounting seat 10.

[0066] Specifically, by arranging the limiting guide part on the shell 21 of the battery pack 20, rotatably arranging the locking member 30 on the mounting seat 10, and arranging the elastic return member 40 between the mounting seat 10 and the locking member 30, the locking part 31 can be quickly accommodated in the limiting guide part by rotating, so that the limiting guide part cooperates with the locking part 31, thereby forming a locking structure limiting the battery pack 20 from separating from the mounting seat 10 along the first direction a, completing the locking of the battery pack 20 by the locking member 30, and the locking can be released by simple screwing operation, which helps to solve the problem of inconvenient taking and placing of the existing battery pack of the electrical equipment.

[0067] It should be understood that the mounting seat 10 has a containing cavity 11 extending along the first direction a, and the containing cavity 11 has an opening at one end. As shown in Figures 2-6 , in this embodiment, the mounting seat 10 is provided in a circular tube structure, and the inside of the mounting seat 10 is provided with an electrical connection seat 50, at this time, the electrical connection seat 50 cooperates with the mounting seat 10 to form the containing cavity 11 with an open end, wherein the axis direction of the mounting seat 10 is the first direction a.

[0068] It should be noted that the mounting seat 10 can be provided in other structures in addition to the circular tubular structure, and the structure of the mounting seat 10 is not limited in the present application. Alternatively, when the mounting seat 10 is in other structures, the mounting seat 10 has a cylindrical mounting portion, and the accommodation cavity 11 is provided in a cylindrical shape and formed on the mounting portion. At this time, the first direction a is the axial direction of the accommodation cavity 11.

[0069] In addition, the mounting seat 10 can be connected to the electrical equipment 1000, and the connection mode can be one of welding, threaded connection, flange connection, clamping, plug-in connection or hoop connection. Of course, the mounting seat 10 can also be provided as part of the housing of the electrical equipment 1000. The electrical equipment 1000 can be a household appliance or a power tool, and the specific form can refer to the following content.

[0070] As shown in Figure 7 , the battery pack 20 is adaptively connected with the mounting seat 10. Specifically, the battery pack 20 has a housing 21 which is adapted to the accommodation cavity 11. In the present embodiment, the housing 21 is provided in a cylindrical structure, and along the first direction a, the housing 21 has an insertion end 22 inserted into the accommodation cavity 11, and an operation end 23 provided outside the accommodation cavity 11. The operation end 23 of the housing 21 is provided with a holding structure to facilitate the hand of the user to hold. The holding structure is not marked in the figure. An insertion port 221 is provided on the end face of the insertion end 22 of the housing 21, and the insertion port 221 is adaptively connected with the battery plug 53 of the electrical connector 50.

[0071] A limiting guide portion is provided on the surface of the housing 21, and further, the limiting guide portion includes a first limiting groove 211 and a second limiting groove 212 connected in sequence. One end of the first limiting groove 211 communicates with the insertion end 22 of the housing 21, and the other end is provided with the second limiting groove 212. In combination with Figure 1 、 Figure 2 and as Figure 8 , the locking member 30 is rotatably provided on the mounting seat 10 with the axis of the mounting seat 10 as the center, and the locking member 30 is provided with a locking portion 31 which extends along the radial direction of the mounting seat 10 to the axis of the mounting seat 10. In the present embodiment, the locking portion 31 is the opening end of the accommodation cavity 11, and at this time, the first distance between the locking portion 31 and the axis of the mounting seat 10 is smaller than the radius of the accommodation cavity 11, that is, the first distance is smaller than the radius of the housing 21. In this way, during the insertion of the battery pack 20, the locking portion 31 can be accommodated in the first limiting groove 211, which helps to ensure the reliability of the battery pack 20 during insertion, so as to ensure the accuracy of the connection between the insertion port 221 and the battery plug 53 after the battery pack 20 is inserted in place.

[0072] In the embodiment, the extending direction of the second limiting groove 212 is perpendicular to the first direction a, and the locking portion 31 has a first locking position and a second locking position due to the rotation of the locking member 30, and the first locking position and the second locking position are arranged at intervals along the rotation direction. In the first locking position, the locking portion 31 can move in the first limiting groove 211, and in the second locking position, the locking portion 31 is accommodated in one end of the second limiting groove 212 away from the first limiting groove 211. In this way, after the battery pack 20 is inserted in place, the position of the locking portion 31 can be adjusted by rotating the locking member 30 to be accommodated in the second limiting groove 212, and the structure of the second limiting groove 212 being perpendicular to the first direction a forms a locking effect of limiting the battery pack 20 from being separated from the accommodation cavity 11, which is simple in structure, easy to operate, and has good locking effect. Compared with existing electric equipment, there is no need to set a battery pack fixing cover, so that the operation of assembling and disassembling the battery pack 20 fixing cover during the taking and placing of the battery pack 20 can be cancelled, which helps to improve the convenience of taking and placing the battery pack 20.

[0073] It should be noted that in addition to arranging the locking portion 31 at the opening end of the accommodation cavity 11, the locking portion 31 can also be arranged at other positions, such as an accommodation cavity 11 having a relief groove, and the locking portion 31 can pass through the relief groove and extend to the inside of the accommodation cavity 11. In this way, the locking effect of the locking member 30 on the battery pack 20 and the assembly effect of cooperating with the first limiting groove 211 can also be achieved.

[0074] In addition, in the embodiment, since the mounting seat 10 has a circular tube structure, the extending direction of the second limiting groove 212 is an arc direction, and the plane where the arc direction is located is perpendicular to the first direction a, that is, the extending direction of the second limiting groove 212 is perpendicular to the first direction a. Of course, in addition to this, the extending direction of the second limiting groove 212 can be a straight line direction, and at this time, along the extending direction of the second limiting groove 212, the depth of the second limiting groove 212 has a trend of first increasing and then decreasing.

[0075] Further, the elastic reset member 40 is arranged between the locking member 30 and the mounting seat 10, one end of the elastic reset member 40 is connected with the locking member 30, and the other end of the elastic reset member 40 is connected with the mounting seat 10. The elastic reset member 40 has a first compression state and a second compression state. In the first compression state, the locking portion 31 has a first locking position, and the locking portion 31 can move in the first limiting groove 211. In the second compression state, the locking portion 31 has a second locking position, and the locking portion 31 can be accommodated in one end of the second limiting groove 212 away from the first limiting groove 211.

[0076] Specifically, by setting the elastic reset member 40, the locking portion 31 has a tendency to move from the first locking position to the second locking position, which on one hand helps to reduce the interference of the outside to the locking member, enables the locking portion 31 of the locking member 30 to return to the second locking position, thereby reducing the operation steps and improving the use effect; on the other hand, enables the locking portion 31 to be maintained in the second locking position for a long time, thereby enabling the locking member 30 to have a better locking effect on the taking and placing of the battery pack 20.

[0077] It needs to be understood that in the present embodiment, the mounting seat 10 is provided in a circular tube structure, the locking member 30 is provided in a tube structure and is sleeved on the mounting seat 10, the elastic reset member 40 is arranged between the mounting seat 10 and the locking member 30, one end of the elastic reset member 40 is connected with the locking member 30, and the other end of the elastic reset member 40 is connected with the mounting seat 10. When the elastic reset member 40 is in the first compression state, the locking portion 31 is in the first locking position, the elastic reset member 40 has an acting force to drive the locking portion 31 to move from the first locking position to the second locking position, and in the second compression state, the locking portion 31 is in the second locking position, and the elastic reset member 40 has an acting force to keep the locking portion 31 in the second locking position.

[0078] In actual use, the user drives the locking member 30 to rotate by external force, at this time, the locking portion 31 moves from the second locking position to the first locking position, the elastic reset member 40 enters the first compression state from the second compression state, the locking portion 31 is in the first locking position and can be accommodated in the first limiting groove 211, thereby ensuring the accuracy of the installation of the shell 21. When the user cancels the external force, the elastic reset member 40 enters the second compression state from the first compression state, at this time, the elastic reset member 40 drives the locking member 30 to rotate, so that the locking portion 31 moves from the first locking position to the second locking position and is maintained in the second locking position. In this process, the locking portion 31 can enter the second limiting groove 212 from the first limiting groove 211 and move to the end of the second limiting groove 212 away from the first limiting groove 211.

[0079] It needs to be further understood that, as Figure 3 , Figure 5 and Figure 9As shown in the drawings, the mounting base 10 is provided with an assembly groove 12 on the outer circumferential surface, and the assembly groove 12 is internally provided with a pivot shaft 121. When the locking piece 30 is sleeved on the mounting base 10, the locking piece 30 blocks the assembly groove 12 and forms an assembly cavity, and at this time, the elastic reset piece 40 is arranged in the assembly cavity. In this embodiment, the elastic reset piece 40 is arranged as a torsion spring, the torsion ring part 41 of the torsion spring is sleeved on the pivot shaft 121, the first supporting part 42 of the torsion spring abuts against the side wall of the assembly groove 12, and the second supporting part 43 of the torsion spring abuts against the driving part 32 of the locking piece 30. Alternatively, the locking piece 30 is of a tubular structure, and the driving part 32 is arranged on the inner wall of the locking piece 30.

[0080] Specifically, the driving part 32 includes a connecting part and an abutting part, both of which are not indicated in the drawings, wherein the thicknesses of the connecting part and the abutting part are different. At the same time, as shown in the drawings, Figure 3 As shown in the drawings, the mounting base 10 is provided with a relief structure 15, and since the locking piece 30 is rotatably arranged on the mounting base 10, the arrangement of the relief structure 15 can effectively guarantee the installation and movement of the driving part 32. Alternatively, the relief structure 15 is arranged as a groove structure, specifically including a first relief groove 151 and a second relief groove 152, wherein the first relief groove 151 is adaptively connected with the abutting part, so as to be used for moving the abutting part in the first relief groove 151, one end of the first relief groove 151 is communicated with the assembly groove 12, so that the abutting part can abut against the second supporting part 43 and enter the assembly groove 12 from the first relief groove 151 along with the movement of the locking piece 30. Correspondingly, the second relief groove 152 is adaptively connected with the connecting part, wherein the extension length and the opening depth of the second relief groove 152 are both greater than those of the first relief groove 151, so as to help guarantee the movement of the abutting part and further guarantee the effect of the driving part 32 on the torsion spring.

[0081] Still as Figure 3 As shown in the drawings, the assembly groove 12 is further provided with a limiting structure 122, and a clamping space is formed between the limiting structure 122 and the side wall of the assembly groove 12, and the first supporting part 42 of the torsion spring is accommodated in the clamping space. In cooperation with the installation of the locking piece 30, the movement of the first supporting part 42 of the torsion spring can be effectively avoided, so as to help guarantee the installation effect of the torsion spring.

[0082] It needs to be further understood that, as Figures 3-6As shown, a mounting structure 14 is provided on the mounting base 10 to allow the locking member 30 to be fitted onto the mounting base 10. Specifically, the mounting structure 14 includes a mounting groove 141 and a limiting spring 142. The mounting groove 141 has a first segment 1411 and a second segment 1412 arranged sequentially. The first segment 1411 extends along a first direction a and is connected to the end of the receiving cavity 11 with an opening. The extension direction of the second segment 1412 is perpendicular to the first direction a. In this embodiment, the extension direction of the second segment 1412 is the circumferential direction of the mounting base 10. Meanwhile, the locking member 30 is provided with an assembly part 33 adapted to the mounting groove 141. The assembly part 33 can enter the second segment 1412 through the first segment 1411 of the mounting groove 141, thereby ensuring that the locking member 30 can be fitted onto the mounting base 10 and rotated. When the locking part 31 is in the first locking position, the assembly part 33 is housed at one end of the second segment 1412 away from the first segment 1411. When the locking part 31 is in the second locking position, the assembly part 33 is housed at one end of the second segment 1412 close to the first segment 1411.

[0083] Still Figure 4 and Figure 5 As shown, a limiting spring 142 is provided at one end of the second segment 1412 near the first segment 1411. When the locking part 31 is in the second locked position, the assembly part 33 is accommodated in the second segment 1412 and abuts against the limiting spring 142. Of course, the limiting spring 142 can also be provided at one end of the first segment 1411 near the second segment 1412. The provision of the limiting spring 142 can, on the one hand, ensure that the assembly part 33 can enter the second segment 1412 through the first segment 1411 of the mounting groove 141, and on the other hand, restrict the assembly part 33 from entering the first segment 1411 from the second segment 1412.

[0084] It should be noted that the number of mounting structures 14 is set to at least one, and when there is only one mounting structure 14, the mounting structure 14 and the aforementioned clearance structure 15 are spaced apart and correspondingly arranged along the circumference of the mounting base 10. When there are at least two mounting structures 14, at least one mounting structure 14 is provided with a limiting spring 142, and the limiting spring 142 can be omitted from the other mounting structures 14.
