Description

Technical Field

[0001] The utility model relates to the technology of automobile structure, in particular to a combination switch. Background Art

[0002] Currently, the light switches used in heavy-duty vehicles generally utilize independent seesaw-type structures. Each of the side marker lights, low beam lights, front fog lights, and rear fog lights is equipped with a corresponding seesaw structure and switch. When assembling the light switch, multiple seesaw structures and switches must be separately mounted on the light switch mounting structure. This occupies a large space, requires numerous components, and is difficult to assemble. Utility Model Content

[0003] The technical problem to be solved by the present invention is that a light switch composed of a seesaw structure and a switch that are independent of each other has many parts and a large external structure. The purpose is to provide a combination switch that reduces the number of parts used, simplifies the structure of the light switch, makes the light switch small in external structure, and reduces the space occupied by the light switch in the car.

[0004] The utility model is achieved through the following technical solutions:

[0005] A combination switch comprises a width light microswitch, a low beam light microswitch, a front fog light microswitch and a rear fog light microswitch connected to a control end, a mounting plate, a torsion bar and a positioning structure, wherein the width light microswitch, the low beam light microswitch, the front fog light microswitch and the rear fog light microswitch are all connected to the mounting plate; a convex ring and a cam are provided on the torsion bar, the convex ring is located below the mounting plate, and the cam is located above the mounting plate, when the torsion bar rotates, the cam drives the width light microswitch and / or the low beam light microswitch to be in an open or closed state; when the torsion bar is pulled up, the convex ring drives the front fog light microswitch to be in a closed state; when the torsion bar is pressed down, the cam drives the rear fog light microswitch to be in a closed state; the positioning structure is connected to the torsion bar to lock the position of the torsion bar.

[0006] Since the existing light switches have a complex structure, many parts, cumbersome assembly procedures and great assembly difficulty, a combination switch is provided for this purpose, in which the width light microswitch, low beam microswitch, front fog light microswitch and rear fog light microswitch are all connected to the mounting plate, and a convex ring and a cam are provided on the torsion bar. By rotating the torsion bar, the cam controls the width light microswitch and low beam microswitch to be opened or closed, the torsion bar is pulled up to control the front fog light microswitch to be closed, and the torsion bar is pressed down to control the rear fog light microswitch to be closed. Instead of using multiple rocker structures to control each microswitches individually, the number of parts used is reduced, the light switch has a small appearance and structure, reduces the space occupied by the light switch in the car, and improves the appearance quality inside the car.

[0007] In some embodiments, the device further includes a housing, the mounting plate being connected to the inner side of the housing, and a through-hole provided in the center of the mounting plate for the protruding ring and the torsion bar to pass through. The housing provides support for the mounting plate, and the through-hole is provided so that when the torsion bar moves upward, the protruding ring passes through the through-hole and moves upward, thereby closing the front fog lamp microswitch and turning on the front fog lamp.

[0008] In some embodiments, the cam is clamped onto the torsion bar, and two protrusions are provided at the bottom of the cam. The two protrusions can respectively abut against the transmission components of the width light microswitch and the low beam microswitch, thereby turning the width light microswitch and / or the low beam microswitch into an open or closed state. The torsion bar is rotated to drive the protrusions to rotate synchronously, and the torsion bar rotates to different angles to enable the lights to have the following states: the width light microswitch and the low beam microswitch are both opened or closed, and the width light and low beam are simultaneously turned on or off; or either the width light microswitch or the low beam microswitch is opened, and either the width light or low beam is turned off.

[0009] In some embodiments, an upper pull block is rotatably connected to the front fog light microswitch. The upper pull block is generally L-shaped. One end of the upper pull block is located above the transmission portion of the front fog light microswitch, and the raised ring can abut against the other end of the upper pull block. When the torsion bar is pulled upward, the upper pull block presses downward on the transmission portion of the front fog light microswitch, and the front fog light microswitch is closed. By pulling the torsion bar upward, the raised ring applies force to one end of the upper pull block, and the end of the upper pull block located above the transmission portion of the front fog light microswitch applies force downward on the transmission portion of the front fog light microswitch, closing the front fog light microswitch and turning on the front fog lights.

[0010] In some embodiments, a pressing block is rotatably connected to the rear fog light microswitch. The pressing block is generally L-shaped, with one end of the pressing block positioned above the transmission portion of the rear fog light microswitch. The disc portion of the cam can abut against the other end of the pressing block. When the torsion bar is depressed, the pressing block depresses the transmission portion of the rear fog light microswitch, placing the rear fog light microswitch in a closed state. Depressing the torsion bar downward causes the convex ring to apply force to one end of the pressing block, which in turn causes the end of the pressing block located above the transmission portion of the rear fog light microswitch to apply force downward to the transmission portion of the rear fog light microswitch, closing the rear fog light microswitch and turning on the rear fog light.

[0011] In some embodiments, the device further comprises a knob, wherein a knob rod is connected below the knob, the knob rod is provided with a latch hole, and the torsion bar is provided with a latch hook, the latch hook cooperates with the latch hole to connect the knob rod to the inner side of the torsion bar. By latching the knob rod to the inner side of the torsion bar, installation and removal are facilitated.

[0012] In some embodiments, a light-sensitive microswitch is further included, the light-sensitive microswitch being connected to the mounting plate and electrically connected to a light sensor and a control terminal, respectively. The light sensor is configured to detect the brightness of the vehicle's driving environment, and the control terminal controls the activation of a light-sensitive lamp based on data from the light sensor, thereby automatically activating the light-sensitive lamp and ensuring driving safety.

[0013] In some embodiments, the positioning structure includes a positioning member and an elastic locking member. The positioning structure is fixedly connected to the inner side of the housing, the elastic locking member is fixedly connected to the torsion bar, and the elastic locking member is slidably connected to the inner side of the positioning member. The elastic locking member abuts against the positioning structure to position the torsion bar in its operated position, ensuring that the light remains in the operated state (on or off) for a long time.

[0014] In some embodiments, three annular grooves are provided on the inner side of the positioning member, each of which extends laterally along the inner side wall of the positioning member. The three annular grooves are sequentially provided along the height direction of the positioning member. The elastic locking member can be located in any of the annular grooves, and the two ends of the elastic locking member can respectively abut against the bottom of the annular grooves. Three annular grooves are provided at different heights of the positioning member so that the elastic locking member can be positioned at three height positions of the torsion bar, ensuring that the lights remain in the operated state for a long time. When the torsion bar is not in the state of being pulled up or pressed down, the elastic locking member is located in the annular groove centered among the three annular grooves. At this time, the front fog lights and rear fog lights are both turned off, and the width marker lights and low beam lights may be turned on or off. When the elastic locking member is located in the annular groove at the upper end or the lower end, at this time, either the front fog lights or the rear fog lights are turned on, and the width marker lights and low beam lights may all be turned on, all turned off, or either turned on.

[0015] In some embodiments, the elastic locking member includes a locking spring, each end of which is provided with a spring sleeve. The torsion bar is provided with a guide portion perpendicular to the torsion bar, and a through hole is provided along the axis of the guide portion. The locking spring is connected to the through hole, and the two spring sleeves are slidably connected to the ends of the through hole. This facilitates the spring sleeve to abut against the bottom of the annular groove, increasing the contact area with the annular groove, ensuring effective positioning, and also facilitates the elastic locking member to slide freely in the three annular grooves, ensuring smooth operation.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0017] 1. Instead of using multiple seesaw structures to control each micro switch individually, the number of parts used is reduced, the light switch has a small structure, which reduces the space occupied by the light switch in the car and improves the appearance quality of the car.

[0018] 2. Set up a photosensitive sensor to detect the brightness of the car's driving environment. The control terminal controls the light to turn on according to the data of the photosensitive sensor, and automatically turns on the light to ensure the safety of the car when driving.

[0019] 3. Three annular grooves are set at different heights of the positioning piece so that the elastic locking piece can be positioned at three height positions of the torsion bar, ensuring that the light is in the operated state for a long time. When the torsion bar is not in the state of being pulled up or pressed down, the elastic locking piece is located in the annular groove in the middle of the three annular grooves. At this time, the front fog lights and rear fog lights are not turned on, and the width marker lights and low beam lights may be turned on or off; when the elastic locking piece is located in the annular groove at the upper end or the lower end, at this time, either the front fog lights or the rear fog lights are turned on, and the width marker lights and low beam lights may be all turned on, all turned off, or either turned on.
