Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a rotary power switch for automobiles. Background Technology

[0002] To promptly cut off the power circuit in case of vehicle malfunction or to prevent battery depletion when the vehicle is not driven for an extended period, a main power switch is typically installed on the vehicle. This power switch can disconnect the power to the entire vehicle. A mechanical power switch mounting structure, disclosed in publication number "CN222483174U", includes a housing with an upwardly protruding tube at the upper end. The tube has an opening at its upper end and an operating shaft inside. To enhance sealing performance, a sealing sleeve made of soft rubber is also included. The sealing sleeve includes a collar fitted onto the outside of the tube, a cap for covering the opening, and a connecting band between the collar and the cap.

[0003] However, in the aforementioned document, the sealing sleeve is attached to the outside of the tube body, which can be easily removed by anyone and is very easy to lose. In addition, the entire sealing sleeve is made of soft rubber material, which is prone to wear and aging under long-term use, which not only reduces the sealing effect but also requires replacement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automotive rotary power switch that prevents the loss of the sealing structure, addressing the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary power switch for automobiles, comprising a base, a bottom cover and a top cover on the base, a stationary contact block at the bottom of the base, a handle mechanism detachably provided at the top of the top cover through an opening, and an actuator capable of abutting or separating from the stationary contact block inside the top and bottom covers, characterized in that: a shell is integrally formed on the outer wall of the top cover, a first mounting block is provided on one side of the shell at the upper end, a rotating hole is opened on the opposite end of the first mounting block, a rotating shaft is rotatably connected in the rotating hole, and a dust cover capable of exposing the opening and covering the opening is rotatably connected on the rotating shaft.

[0006] The above technical solution addresses the issue that, unlike existing technologies where the sealant is attached to the outside of the tube and can be easily removed and lost, this invention uses a shell integrally formed with the top cover and a dust cover hinged to the shell. This prevents the dust cover from being easily removed. In use, simply disassemble the handle mechanism and then close the dust cover at the opening of the top cover to achieve dust and water protection. Furthermore, the preferred dust cover is made of flame-retardant nylon material, which improves wear resistance and extends service life compared to soft rubber materials.

[0007] A further feature of this invention is that a second mounting block is provided on the side of the dust cover near the housing, a mounting groove for inserting the second mounting block is formed between the first mounting blocks, and a mounting hole for the rotating shaft to pass through is provided on the second mounting block.

[0008] The above technical solution is adopted: by setting the second mounting block, during the installation process, the rotating shaft is simply inserted into the second mounting block through the mounting hole, and then both ends of the rotating shaft are respectively inserted into the rotating holes on the first mounting block to complete the hinge between the dust cover and the housing, so that the rotation of the dust cover can expose the opening and cover the opening.

[0009] A further feature of this invention is that the dust cover has a chamber for the top of the cover to be accommodated, the chamber has a sealing ring groove along its inner wall, a sealing ring is provided in the sealing ring groove, and a sealing block with the same shape as the opening is also provided in the chamber.

[0010] The above technical solution is adopted: by setting the sealing ring, when the dust cover is closed at the opening, the sealing ring is located between the dust cover and the outer wall of the upper cover, which improves the sealing effect and plays a waterproof role. At the same time, the shape of the sealing block is consistent with the shape of the opening, which further improves the sealing effect.

[0011] A further feature of this invention is that a third mounting block is provided on the side of the dust cover away from the second mounting block, and a buckle is hinged to the third mounting block. A corresponding latching block is provided on the side of the housing away from the first mounting block, and a latching groove is provided on the buckle for the latching block to pass through.

[0012] The above technical solution is adopted: by setting the buckle, when the dust cover is closed at the opening, the buckle is flipped down so that the buckle passes through the snap-fit ​​groove and the buckle is fastened to the shell. This can prevent the dust cover from being opened by external forces other than human factors and ensure the sealing effect.

[0013] A further feature of this invention is that the handle mechanism includes a handle body, a pin is provided laterally in the lower part of the handle body, an insertion groove for installing the pin is provided at the opening of the upper cover, an abutment platform is provided inside the upper cover below the insertion groove to abut the pin, a power-off position groove is provided on the left and right sides of the abutment platform, and a power-on position groove is provided on the front and rear sides of the side wall of the abutment platform, the depth of the power-on position groove is greater than the depth of the power-off position groove, the power-off position groove and the power-on position groove are connected by an inclined surface, and a through hole is provided in the middle of the abutment platform.

[0014] The above technical solution is adopted as follows: During use, when the power is off, the pin is located in the power off position slot. When power supply is required, the handle body is rotated to drive the pin to rotate into the power on position slot, so that the lower end of the handle body can cause the actuator to move downward and then abut against the stationary contact block to realize power supply.

[0015] A further feature of this invention is that the actuator includes a push rod, a movable contact block is provided on one end of the push rod near the stationary contact block, and a support ring and a spring seat are provided on the outer sleeve of the push rod; the spring seat includes an upper spring seat and a lower spring seat, an upper spring slot and a lower spring slot are respectively provided on opposite sides of the upper spring seat and the lower spring seat, and the spring slot and the lower spring slot form a spring cavity, a spring is provided in the spring cavity, the support ring is disposed between the lower spring seat and the contact block, and a return spring is provided at the point where the base and the push rod cooperate.

[0016] The above technical solution is adopted as follows: During use, when power supply is required, rotating the handle body drives the push rod downward, thereby causing the moving contact to abut against the stationary contact to achieve power supply. At the same time, the spring setting ensures that the moving contact and the stationary contact are always abutting. In addition, through the setting of the return spring, when power is cut off, the moving contact moves upward with the push rod through the handle body in the opposite direction. The return spring has the effect of automatically returning the moving contact to its original position, improving stability.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description
