[0027] Referring to Figures 1-4 , according to an embodiment of a horn switch of the present utility model, it includes a base 11 and a switch body embedded in the base 11. A pressing member 13 is also slidably connected in the base 11. A trigger post 14 extending out of the switch body abuts against the pressing member 13. When a user presses down the pressing member 13, the pressing member 13 will cause the circuit in the switch body to close through the trigger post 14, thereby causing the horn to work. When the user releases the pressing member 13, the built-in spring in the switch body will cause the trigger post 14 and the pressing member 13 to reset upward.

[0028] In order to enable the shape of the switch body to change for the convenience of user control, a hinge groove 15 is provided in the upper side surface of the switch body. A hinge rod 17 is provided in the hinge groove 15, and a control board 16 is mounted on the hinge rod 17. A positioning mechanism for controlling the angle of the control board 16 is also included.

[0029] The articulated rod 17 is close to the right curved surface of the switch body. A chamfer is formed between the right side surface of the articulated groove 15 and the upper side surface of the pressing member 13 to form a first inclined surface. When the control board 16 flips, its original upper side surface can abut against the first inclined surface.

[0030] In addition, in order to enable the control board 16 to extend laterally outside the base 11 when the control board 16 abuts against the first inclined surface, so as to be close to the thumb of the palm of the user holding the handle of the battery vehicle, the distance between the axis of the articulated rod 17 and the switch body is greater than the minimum value of the distance between the articulated rod 17 and the outer curved surface of the switch body.

[0031] When the control board 16 is embedded in the articulated groove 15, the base 11 is integrally cylindrical, and the user can control the pressing member 13 by pressing the front surface of the control board 16;

[0032] When the control board 16 flips and abuts against the first inclined surface, the user can press the control board 16 extending outside the base 11 to press the pressing member 13, and at this time, the adjustment of the control distance of the pressing member 13 is completed.

[0033] The articulated rod 17 is fixed in the articulated groove 15, and the control board 16 is rotatably connected to the outside of the articulated rod 17. The positioning mechanism includes a hollow groove 31 provided in the control board 16 and penetrated by the articulated rod 17. A plug board 19 is slidably connected horizontally in the hollow groove 31, and two positioning grooves 20 for accommodating the plug board 19 are provided in the outer curved surface of the articulated rod 17.

[0034] A spring groove 21 is provided in the side surface of the plug board 19, and a spring plate 22 extending into the spring groove 21 is provided on the side surface of the hollow groove 31. The spring plate 22 is connected to the side surface of the spring groove 21 through a spring. The user can move the plug board 19 to the left to make it leave the positioning groove 20, and then the user can flip the control board 16 to rotate it relative to the articulated rod 17. The plug board 19 can be embedded in different positioning grooves 20 so that the plug board 19 abuts against the bottom surface of the articulated groove 15 or abuts against the first inclined surface and is in a flipped state.

[0035] In order to facilitate the user to control the left and right positions of the plug board 19, a pressing block 23 extending into the spring groove 21 is slidably connected up and down in the control board 16. An inclined chamfer is formed between the lower side surface and the left side surface of the spring groove 21 to form a second inclined surface, and the lower edge of the pressing block 23 is attached to the second inclined surface. The pressing block 23 is limited and cannot leave the control board 16. When the pressing block 23 is pressed down, the plug board 19 will be pushed to the left through the inclined surface so that it leaves the positioning groove 20. When the pressing block 23 is no longer pressed, the spring will push the plug board 19 to the right and make it tend to be inserted into the positioning groove 20.

[0036] In order to make it easier for the user to press the control board 16 when the control board 16 is in a flipped state, an extension board 24 extending upward to the left is provided at the left edge of the control board 16. With this setting, when the control board 16 is flipped and attached to the first inclined surface, the extension board 24 is in a parallel state and is located on the right side of the base 11, which is convenient for the user to press. An inclined chamfer is formed between the left side surface of the hinge groove 15 and the upper side surface of the switch body to form a third inclined surface for accommodating the extension board 24. The third inclined surface is symmetrically arranged with the first inclined surface left and right.

[0037] In order to prevent the pressing member 13 from being in an inclined state when the control board 16 is in a flipped state and is pressed, which may accelerate the wear of the pressing member 13, a partition 25 is integrally formed on the outer curved surface of the base 11. A support plate 26 is provided on the upper side surface of the partition 25. The left side surface of the support plate 26 is attached to the right curved surface of the pressing member 13. The function of the partition 25 is that when the horn switch is installed, the support plate 26 is attached to the upper edge of the installation platform.

[0038] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
