[0031] Reference will be made below to Figures 1 to 5 describe the switch assembly according to an embodiment of the present utility model.

[0032] As Figures 1 to 3 shown, the switch assembly according to an embodiment of the present utility model includes a switch module 100, a circuit board assembly 200 connected to the rear end of the switch module 100, and a switch cover 300 covering the circuit board assembly 200. The switch cover 300 is provided with a cavity 301 having an open end structure, and the switch cover 300 is provided with hooks 310. The switch cover 300 can be sleeved into the circuit board assembly 200 along the length direction of the switch assembly through the open end structure, and the hooks 310 can be hooked on the circuit board assembly 200, so that the switch cover 300 can be detachably covered on the circuit board assembly 200, which is convenient for disassembly and assembly, convenient for battery replacement or circuit board maintenance, and the switch cover 300 can be stably covered on the circuit board assembly 200 through the hooks 310 and is not easy to fall off. The switch cover 300 is stably and reliably installed and can play a good role in protecting the circuit board assembly 200.

[0033] Specifically, the circuit board assembly 200 is fixedly connected to the rear end of the switch module 100. The circuit board assembly 200 includes a circuit board, a power supply assembly 220 or other electronic components, etc. The hooks 310 can be hooked on the edge position of the circuit board, so as to fix the switch cover 300 to the circuit board assembly 200 and complete the protection of the circuit board assembly 200. When disassembly is required, the hooks 310 can be lifted to make them fall off the edge position of the circuit board.

[0034] It can be understood that in some embodiments of the present utility model, hole positions can also be provided on the circuit board to cooperate with the hooks 310.

[0035] In some embodiments of the present utility model, the open end structure of the switch cover 300 abuts against the switch module 100, and in cooperation with the hook connection between the hooks 310 and the circuit board assembly 200, the stability of the installation of the switch cover 300 is improved.

[0036] Specifically, the switch module 100 generally has a hard shell such as metal or plastic. The open end structure of the switch cover 300 abuts against the hard shell of the switch module 100 to perform front positioning on the switch cover 300 (the switch cover 300 cannot move forward). When the hooks 310 are hooked on the circuit board assembly 200, rear positioning is performed on the switch cover 300 (the switch cover 300 cannot move backward), thereby improving the stability of the installation of the switch cover 300.

[0037] As Figure 3 、Figure 5 As shown, in some embodiments of the present utility model, a flaring structure 302 is provided at the inner edge of the opening structure of the switch cover 300. The flaring structure 302 can cooperate with the rear end of the switch module 100 to improve the installation stability of the switch cover 300.

[0038] Specifically, a chamfer is provided at the inner edge of the opening structure of the switch cover 300, so that the opening structure forms a flaring structure that gradually expands from the rear to the front, which can be inserted into and closely abutted against the rear end part of the switch module 100, improving the installation stability of the switch cover 300.

[0039] In some embodiments of the present utility model, the switch cover 300 is provided with a driving mechanism capable of driving the hook 310 to disengage from the circuit board assembly 200 to facilitate the disassembly and assembly of the switch cover 300.

[0040] As Figures 1 to 5 shown, in some embodiments of the present utility model, the driving mechanism is a pressing handle 330. One end of the pressing handle 330 is a connecting end 331 connected to the housing main body 320 through a rotatable structure, and the other end of the pressing handle 330 is a pressing end 332 suspended relative to the housing main body 320. The hook 310 is connected to the connecting end 331 of the pressing handle 330 and extends forward from the connecting end 331. By pressing the pressing end 332, the pressing handle 330 rotates clockwise, thereby driving the hook 310 to rotate clockwise to a position where it disengages from the circuit board assembly 200, thus facilitating the disassembly of the switch cover 300.

[0041] It can be understood that in some embodiments of the present utility model, the driving mechanism can also be a pulling ear or the like provided above the hook 310.

[0042] As Figure 4 、 Figure 5 shown, in some embodiments of the present utility model, the switch cover 300 includes a housing main body 320. Below the connecting end 331 is a hollow structure 334, and the rotatable structure is support arms 333 respectively provided on both sides of the connecting end 331 and connected to the housing main body 320. Pressing the pressing end 332 downward can cause the support arms 333 to be distorted and deformed to drive the hook 310 to lift and disengage from the circuit board assembly 200, thereby realizing the disassembly function of the switch cover 300.

[0043] Specifically, the switch cover 300 is integrally formed by injection molding with a plastic material. The support arms 333 have certain distortion and reset performance, that is, the support arms 333 can be twisted at a small angle, thereby realizing the rotational support of the pressing handle 330, facilitating the disassembly of the switch cover 300, and making use of the material characteristics of the plastic to enable the hook 310 to have a reset function, so that it can stably hook the circuit board assembly 200 in the assembled state, improving the reliability of the covering structure.

[0044] It can be understood that in some embodiments of the present utility model, the switch cover 300 can be a metal cover, and a plastic part or a thin metal plate part can be used at the support arm 333, which can also meet the requirement of small-angle rotation of the support arm 333.

[0045] It can be conceived that in some embodiments of the present utility model, the rotatable structure can also be a rotating shaft connecting the housing main body 320 and the pressing handle 330, and a torsion spring can be arranged at the rotating shaft to realize the reset of the hook 310.

[0046] As Figure 4 、 Figure 5 shown, in some embodiments of the present utility model, the switch cover 300 is integrally in a cylindrical structure. The switch cover 300 includes a front section 340 and a rear section 350 extending backward from the front section 340. The rear section 350 is provided with a concave structure 351. Two support arms 333 are arranged at one end of the front section 340 close to the rear section 350. The hollow structure 334 penetrates the joint end face of the front section 340 and the rear section 350, so as to form a cantilever structure with the two support arms 333; the connection end 331 is located between the two support arms 333, the pressing end 332 extends backward toward the rear section 350, and a gap is formed between the pressing end 332 and the upper end face of the concave structure 351, so that the pressing end 332 is suspended relative to the rear section 350; the hook 310 extends forward from the connection end 331 to the front section 340, and the front section 340 is provided with an avoidance clearance 353 corresponding to the hook 310, so as to meet the setting requirements of the pressing handle 330 and the hook 310.

[0047] Specifically, by providing the concave structure 351 corresponding to the pressing handle 330 at the rear end 350, the pressing handle 330 will not protrude from the projection in the length direction of the switch cover 300. The setting of the pressing handle 330 will not affect the normal installation of the switch assembly, and the pressing handle 330 is not easily accidentally touched to cause the hook 310 to disengage, improving the reliability.

[0048] As Figure 4 、 Figure 5 shown, in some embodiments of the present utility model, reinforcing parts 352 are arranged to extend downward on both sides of the avoidance clearance 353 to improve the structural strength of the opening structure of the switch cover 300.

[0049] As Figure 4 、 Figure 5 shown, in some embodiments of the present utility model, the switch cover 300 is integrally in a cylindrical structure. A planar structure 303 corresponding to the circuit board assembly 200 is arranged at the bottom of the cavity 301 to form a flat bottom structure to facilitate the stable accommodation of the circuit board assembly 200.

[0050] Specifically, as Figure 2As shown, the switch assembly as a whole is generally cylindrical in structure, adapted to the corresponding hole positions. The switch cover 300 is correspondingly cylindrical as a whole. The circuit board assembly 200 includes a battery assembly 220. The battery assembly 220 is arranged on the main mounting plate 230. The main mounting plate 230 extends along the length direction of the switch cover 300. The battery assembly 220 can be a battery box assembly or a rechargeable battery pack, etc. A vertical plate 210 is fixedly arranged at the front end of the main mounting plate 230. The circuit board assembly 200 is generally rectangular parallelepiped in structure as a whole. By providing the planar structure 303, the circuit board assembly 200 can be placed compactly and stably into the switch cover 300, and the front end of the switch cover 300 can be better matched with the switch module 100.

[0051] In some embodiments of the present invention, the rear section 350 is provided with a concave structure 351. The concave structure 351 cooperates with the planar structure 303, making the cooperation between the switch cover 300 and the circuit board assembly 200 more compact.

[0052] As Figure 2 、 Figure 3 As shown, in some embodiments of the present invention, the circuit board assembly 200 includes a vertical plate 210 fixedly connected to the switch module 100. The vertical plate 210 is perpendicular to the length direction of the switch assembly or the vertical plate 210 forms an angle with the length direction of the switch assembly. The hook 310 can be hooked on the vertical plate 210, thereby fixing the switch cover 300 to the circuit board assembly 200.

[0053] It can be understood that, in some embodiments of the present invention, the hook 310 can also be hooked on other positions of the circuit board assembly 200, such as the leading edge of the main mounting plate 230 or the outer edge of the battery box of the battery assembly 220.

[0054] As Figure 2 、 Figure 3 As shown, in some embodiments of the present invention, the switch module 100 extends backward to be provided with a plug-in portion 110. The vertical plate 210 is provided with a plug-in hole 211 corresponding to the plug-in portion 110. After the plug-in portion 110 is inserted into the plug-in hole 211, it is welded and fixed to the vertical plate 210, thereby stably fixing the vertical plate 210 and the circuit board assembly 200 to the rear end of the switch module 100 and realizing electrical connection.

[0055] Specifically, the plug-in hole 211 of the vertical plate 210 is provided with a circuit connecting the battery assembly 220. After the plug-in portion 110 is inserted into the plug-in hole 211, it is welded and fixed to the vertical plate 210, realizing the electrical connection between the switch module 100 and the battery assembly 220. At the same time, the vertical plate 210 can be stably fixed to the rear end of the switch module 100. When the hook 310 is hooked on the vertical plate, the switch cover 300 can be firmly fixed to the switch assembly.
