DETAILED DESCRIPTION

[0040] Hereinafter, with reference to the accompanying drawings, an electric vehicle headlamp light adjusting structure which is one embodiment of the present application is described.

[0041] Please refer to Figures 1-7 , an electric vehicle headlamp light adjusting structure, comprising a headlamp main body, further comprising an adjusting assembly for adjusting the headlamp main body;

[0042] The headlamp main body is derived from the prior art and is used for lighting. The adjusting assembly comprises an adjusting part and a control part. The adjusting part is used for adjusting the lighting direction of the headlamp main body. The control part is used for realizing mechanical control between the user and the adjusting part.

[0043] Regarding the headlamp main body (only the structure is shown in the drawings, and the size ratio between each part is not limited), comprising:​​​

[0044] Lamp holder 1, used as a base;

[0045] Adjustment plate 101 is rotatably mounted inside lamp holder 1;

[0046] Lamp holder 102 is fixedly installed on one side of adjustment plate 101;

[0047] The lamp body 103 is electrically connected to the lamp holder 102;

[0048] The lampshade 104 is disposed on one side of the lamp holder 1 and located inside the lamp body 103;

[0049] The power terminal 101b is located on the side of the adjustment plate 101 away from the lamp holder 102 and is electrically connected to the lamp holder 102;

[0050] Specifically, the aforementioned lamp holder 1, lamp base 102, lamp body 103 and lamp shade 104 are all derived from existing technology, and their structure, principle and installation method will not be described in detail;

[0051] Regarding the regulating section, it includes:

[0052] The rotating shaft 101c is located between the adjusting plate 101 and the lamp holder 1;

[0053] Specifically, the rotating shaft 101c is fixed to the adjusting plate 101, and there are two of them symmetrically arranged around the center of the adjusting plate 101 on the outer edge of the adjusting plate 101. Each rotating shaft 101c extends through the lamp holder 1 to the outside of the lamp holder 1.

[0054] More specifically, under the limitation of the rotating shaft 101c, the lamp holder 1 is a ring and the adjusting plate 101 is a circular plate. The extension lines of the two rotating shafts 101c pass through the center of the lamp holder 1 and the center of the adjusting plate 101. That is, the rotation of the lamp holder 1 and the adjusting plate 101 is a rotation of the outer edge of the fixed center. The side wall of the lamp holder 1 and the adjusting plate 101 can form an angle under the limitation of the rotating shaft 101c.

[0055] The outer edge of the adjustment plate 101 is provided with an arc-shaped protrusion 101a, and the inner wall of the lamp holder 1 is provided with an arc-shaped groove corresponding to the adjustment plate 101. The arc-shaped protrusion 101a and the arc-shaped groove are adapted to achieve the sealing of the rotating part during the rotation of the adjustment plate 101 and the lamp holder 1.

[0056] Furthermore, the length of the arc-shaped groove provided on the inner wall of the lamp holder 1 is the swing range of the adjustment plate 101;

[0057] The regulating unit also includes:

[0058] The transmission gear 2 is mounted on one of its rotating shafts 101c and is located outside the lamp holder 1;

[0059] The first adjusting shaft 201 rotates on the outer wall of the lamp holder 1 and is located on one side of the transmission gear 2;

[0060] The outer wall of the first adjusting shaft 201 is provided with adjusting teeth 201a that mesh with the transmission gear 2;

[0061] That is, when the first adjusting shaft 201 rotates, it can drive the transmission gear 2 to rotate, thereby driving the rotating shaft 101c and the adjusting plate 101 to rotate, realizing the deflection of the adjusting plate 101, and realizing the deflection adjustment of the lamp holder 102 and the lamp body 103;

[0062] A dust cover is provided on the outside of the transmission gear 2 and the first adjusting shaft 201, and the dust cover is installed on the outer wall of the lamp holder 1;

[0063] Specifically, the minimum transmission ratio of the adjusting gear 201a and the adjusting gear 201a wheel is 1:5. This setting enables labor-saving transmission and is convenient for users.

[0064] The control unit includes:

[0065] Mounting cylinder 204 is used as a base to support components. Mounting cylinder 204 is installed on the handlebars, instrument housing, or headgear of the electric vehicle according to user requirements.

[0066] Handwheel 203 is rotatably mounted on the top of mounting cylinder 204;

[0067] The second adjusting shaft 202 is disposed on the end face of the handwheel 203 and located on the inner wall of the mounting cylinder 204;

[0068] Two straps 204a are provided on the outside of the mounting cylinder 204.

[0069] One strap 204a has a through hole 204b, and the other strap 204a has a matching limiting protrusion 204c.

[0070] In use, the two straps 204a are wrapped around the handlebars of the electric vehicle or the remaining tubular parts on the electric vehicle that can be wrapped with the straps 204a. The ends of the two straps 204a are stacked, and the limiting protrusion 204c is passed through the through hole 204b to fix the straps 204a, thereby fixing the mounting cylinder 204.

[0071] Both the regulating and control units include:

[0072] Adjustment cable 201c is configured as a closed rope or wire rope, which is wound around the outer wall of the first adjustment shaft 201 and the second adjustment shaft 202;

[0073] Among them, the adjusting cable 201c is wound into a coil 201b on the outer wall of the first adjusting shaft 201 and the second adjusting shaft 202;

[0074] The 201b spool has at least 4 turns;

[0075] The purpose of this configuration is to transmit power from the first adjustment shaft 201 to the second adjustment shaft 202. That is, when the first adjustment shaft 201 and the second adjustment shaft 202 are respectively fixed on different planes, rotating the first adjustment shaft 201 causes the adjustment cable 201c to rotate synchronously with the first adjustment shaft 201 due to the friction of the wire coil 201b. Since the adjustment cable 201c is a closed rope or wire rope, the friction of its other wire coil 201b with the second adjustment shaft 202 can also achieve synchronous rotation, thus realizing the power transmission from the first adjustment shaft 201 to the second adjustment shaft 202. When the user rotates the first adjustment shaft 201, the second adjustment shaft 202 can be driven to rotate under the action of the adjustment cable 201c and the two wire coils 201b. Combined with the aforementioned description of the rotation of the first adjustment shaft 201, the lamp body 103 can be driven to rotate.

[0076] Specifically, rubber pads 201d are provided on the outer walls of the first adjusting shaft 201 and the second adjusting shaft 202 at the locations corresponding to the coil 201b, in order to further enhance the friction.

[0077] Compared with the prior art, this utility model has the following characteristics:

[0078] The arc-shaped protrusion 101a and arc-shaped groove are provided to improve the sealing effect while allowing the adjustment plate 101 and the lamp holder 1 to rotate relative to each other.

[0079] Based on the setting of the adjustment shaft, wire reel 201b, and adjustment cable 201c, manual mechanical adjustment is adopted. With the dustproof function of the dust cover and the mounting cylinder 204, the reliability of the dimming structure is greatly improved, which can be used for a long time. It is simple to operate and easy to maintain.

[0080] Thanks to the straps 204a and the adjustment cable 201c, the control unit can adjust the mounting position on the electric vehicle according to the user's needs, making it widely applicable.

[0081] This utility model is not limited to any particular implementation method; various modifications can be made as long as the principle is not violated.
