[0041] Example

[0042] Combination Figures 1 to 6 As shown, this embodiment provides a multi-stage contact conductive assembly for electrically connecting a battery pack assembly 10 and a circuit board 9, comprising a seat 1, a first contact assembly having a plurality of first elastic contacts 2, and a second contact assembly having a plurality of second elastic contacts 3; the seat 1 is used to connect the bracket 18 of the battery pack assembly 10; the first elastic contact 2 is arranged on the seat 1, used to abut against the electrode of the battery pack and provide a conductive contact surface 8; the second elastic contact 3 is used to connect the circuit board 9 and abut against the conductive contact surface 8. Specifically, in this embodiment, as Figures 2 to 5 As shown, the first elastic contact piece 2 and the second elastic contact piece 3 are both provided with a fixed portion 4 and an elastic movable portion; the elastic movable portion includes three sections. The first section 5 of the elastic movable portion is connected to the fixed portion 4 at an angle of 90 degrees, the second section 6 is connected to the first section 5 at an angle of 120 degrees, and the third section 7 is connected to the second section 6 at an angle of 90 degrees.

[0043] The conductive contact surface 8 is formed on the upper end surface of the fixed portion 4 of the first elastic contact piece 2 through the setting of the first contact piece assembly to achieve quick contact with the electrode of the battery pack, and provides a conductive contact surface 8, which is contacted with the conductive contact surface 8 through the setting of the second contact piece assembly to achieve conduction with the circuit board 9.

[0044] Preferably, rounded corners are provided at the connection between the fixing part and the first section 5, at the connection between the second section 6 and the first section 5, and at the connection between the third section 7 and the second section 6. On the one hand, it facilitates the installation of the elastic contact piece in a compact and narrow space. On the other hand, it can also increase the contact area between the connection between the third section 7 and the second section 6 and the battery pack electrode or the conductive contact surface 8 to ensure the conduction of the battery power supply output. The shape of the fixing part 4 can be adaptively changed and adjusted according to the part to be fixed. In this embodiment, the shape of the fixing part 4 of the second elastic contact piece 3 is different from that of the fixing part 4 of the first elastic contact piece 2 and can be regarded as a C-shaped to facilitate the fixed connection of the second elastic contact piece 3.

[0045] In this embodiment, the battery pack can be a rechargeable and recyclable power supply battery with metal contact pieces. The materials of the electrodes of the battery pack, the first elastic contact piece 2, and the second elastic contact piece 3 can be silver, copper, aluminum, nickel, or stainless steel, etc.

[0046] One side of the bracket 18 is open to form a battery compartment. There is a second opening 35 at one end of the battery compartment for the first elastic contact piece 2 to extend into the battery compartment, so that the elastic movable part of the first elastic contact piece 2 extends into the battery compartment and abuts against the electrode of the battery pack. The seat body 1 is provided with open areas at intervals for the conductive contact surface 8 to be exposed. A plurality of open areas are arranged in parallel. The seat body 1 is relatively located at the second opening 35 of the battery compartment and fixes the first elastic contact piece 2, and the seat body 1 is fixedly connected or detachably connected to the bracket 18.

[0047] The present utility model also provides a lamp, as Figures 7 to 17 shown, which includes a housing 11, a circuit board 9 placed in the housing 11, a lamp body assembly 12 arranged on the housing 11 and electrically connected to the circuit board 9, and a battery pack assembly 10 detachably arranged in the housing 11. It also includes the multi-stage contact piece conduction assembly; the seat body 1 is arranged on the bracket 18 of the battery pack assembly 10, and the first elastic contact piece 2 abuts against the electrode of the battery pack; the second elastic contact piece 3 is connected to the circuit board 9 and abuts against the conductive contact surface 8 of the first elastic contact piece 2. The lamp body assembly 12 is provided with a lens, a lamp board, and a heat dissipation board in sequence from the surface to the inside. The lens is hermetically arranged with the housing through a sealing ring to ensure the waterproof effect of the lamp body; the lamp board is electrically connected to the circuit board 9.

[0048] As Figures 8 to 11 shown, the housing 11 is a hollow cavity 14 provided with a first opening 15 at one end, and a card slot 16 is provided on the inner side surface of the first opening 15 end; one end of the battery pack assembly 10 is provided with a clamping assembly 19; the battery pack assembly 10 can pass through the first opening 15 and be manually clamped and locked with the card slot 16 through the clamping assembly 19 to be detachably installed in the hollow cavity 14.

[0049] A plurality of reinforcing ribs and assembly spaces are respectively provided on both sides of the hollow cavity 14 to ensure the stability of the hollow cavity 14 and the shell 11. The volume of the lamp is reduced as much as possible through the hollow cavity 14 and the remaining assembly space on both sides, making the lamp easy to carry and store.

[0050] like Figures 12 to 15 As shown, the clamping assembly 19 includes a slider 20, two lock buckles 21, and a cover plate 22; the slider 20 has triangular side plates 26 on both sides, and the side plates 26 are wide at the bottom and narrow at the top; the slider 20 is used to drive the two lock buckles 21 to move synchronously to approach or move away from the clamping slot 16; the cover plate 22 is used to install the slider 20 and the lock buckle 21 on one end surface of the bracket 18; specifically, the cover plate 22 is provided with a second sliding groove 34, and the operating part of the slider 20 can be slidably set on the second sliding groove 34.

[0051] Specifically, two first sliding grooves 24 are arranged opposite to each other on one end surface of the bracket 18, a retaining wall 25 is arranged between the two first sliding grooves, the lock buckle 21 is arranged on the first sliding groove 24, and a first spring 23 is arranged between the lock buckle 21 and the retaining wall 25; the first spring 23 is used to keep the two lock buckles 21 away from each other. The lock buckle 21 includes a clamping portion 27 and a driving portion 28, and the driving portion 28 is placed inside the side plate 26 of the slider 20. When the battery pack assembly 10 passes through the first opening 15 into the hollow cavity 14, the two lock buckles 21 are squeezed by the side of the first opening 15, thereby overcoming the elastic force of the first spring 23 and approaching each other. The battery pack assembly 10 continues to move into the hollow cavity 14 until the lock buckle 21 is opposite to the card slot 16. Under the action of the elastic force of the first spring 23, the two lock buckles 21 move away from each other, and the clamping portion 27 of the lock buckle 21 is inserted into the card slot 16, thereby fixing the battery pack assembly 10. When the battery pack assembly 10 needs to be removed, the slider 20 only needs to be slid upward. Since the side plate 26 is wide at the bottom and narrow at the top, when it slides upward, the side plate 26 will drive the driving portions 28 of the two lock blocks to approach each other, so that the lock blocks overcome the elastic force of the first spring 23, and then the clamping portion 27 is separated from the card slot 16, so that the battery pack assembly 10 can be taken out of the hollow cavity 14.

[0052] Preferably, a second spring 17 is provided at the other end of the hollow cavity 14 opposite to the first opening 15. When the slider 20 drives the clamping portion 27 to disengage from the clamping slot 16, the battery pack assembly 10 is ejected under the action of the elastic force of the second spring 17, so that the battery pack assembly 10 can be taken out of the hollow cavity 14 more quickly.

[0053] Preferably, if Fig.16 and Fig.17 As shown, it also includes a rotating bracket 13 rotatably arranged on the housing 11, and a magnet 33 arranged on the rotating bracket 13. The rotating bracket 13 is provided with a rotating tooth 29; the housing 11 is elastically provided with a gear block 30 adapted to the rotating tooth 29. Specifically, as Fig.16 and Fig.17 As shown, the rotating bracket 13 is connected to both ends of the housing through a rotating shaft 32, and the rotating shaft 32 is arranged on the housing body 11 through a rotating shaft cover 31. Rotating teeth 29 are arranged at both ends of the rotating bracket 13, and a gear block 30 is protruded from the housing body through a third spring; when the rotating bracket 13 rotates, the gear block 30 is compressed back into the housing body 11, and after stopping the rotation, the gear block 30 is embedded in the rotating teeth 29 for limiting, so that the rotating bracket 13 stops rotating. The magnet 33 is convenient for fixing the lamp, and the lighting angle is adjusted in conjunction with the rotation of the rotating bracket 13.

[0054] The lamp is provided with the multi-stage contact piece conduction assembly, and the first contact piece assembly is provided to achieve quick contact with the electrode of the battery pack, and provide a conductive contact surface 8, and the second contact piece assembly is provided to abut against the conductive contact surface 8 to achieve conduction with the circuit board 9. Thus, the battery pack assembly 10 can be quickly disassembled and assembled with the lamp body, without the need for wire connection inside the housing 11, saving the internal space of the housing 11; at the same time, the battery in the battery pack assembly 10 can also be quickly disassembled and assembled with the bracket 18.
