[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Example 1

[0046] Please refer to Figures 1-4 One embodiment of this utility model provides a projection vehicle light, including: a vehicle light housing 10, a projection module 20, and a controller 30;

[0047] The headlight housing 10 includes a coaxially arranged outer shell 11 and a sleeve 12, one end of which is provided with an outlet 13; a third lens 16 is provided on the outlet (13);

[0048] The projection module 20 includes at least an optical component 21, a screen panel 22, and a reflector 23. The optical component 21 is disposed inside the housing 11. The screen panel 22 is disposed in the optical path of the headlight beam emitted by the optical component 21. The reflector 23 is disposed at the end of the sleeve 12 and is used to receive the headlight beam passing through the screen panel 22 and to emit the headlight beam from the outlet 13.

[0049] The controller 30 is disposed on the top or side of the headlight housing 10;

[0050] The optical component 21 includes at least a lamp cup 211, a light source 212, a first lens 213, and a second lens 214. The light source 212 is disposed at the bottom of the lamp cup 211, and the first lens 213 and the second lens 214 are arranged sequentially inside the lamp cup 211 along the light path of the light source 212.

[0051] The first lens 213 is configured as a beam expander, and the second lens 214 is configured as a collimator.

[0052] In this embodiment, the parabolic curved surface design of the lamp cup 211 improves the luminous efficiency of the light source 212 and reduces beam loss. The first lens 213 and the second lens 214 are used to expand and collimate the light emitted by the light source 212. The collimated beam is the headlight beam.

[0053] By setting the screen panel 22 in the optical path of the headlight beam, the headlight beam can carry the information on the screen panel 22 and illuminate the reflector 23. The reflector 23 refracts the beam to the third lens 16, and the headlight beam is then projected onto the illuminated plane, such as the ground or a wall, thus forming a projection with the information from the screen panel. Therefore, this invention allows the headlight to have both lighting and projection functions. When the projection headlight of this invention is applied to balance bikes, bicycles, or motorcycles, it can not only achieve basic lighting functions but also meet the needs of vehicle drivers for personalized projection.

[0054] Example 2

[0055] Based on Example 1, please refer to Figures 2-3 The outer casing 11 is also provided with a fixing seat 14, and the lamp cup 211 is fixedly sleeved in the fixing seat 14;

[0056] In one application scenario of this embodiment, the outer shell 11 and the fixing base 14 are aluminum alloy accessories made of the same material;

[0057] In another application scenario of this embodiment, heat dissipation fins are provided on the outer side of the fixing base 14.

[0058] In this embodiment, by using the mounting bracket 14 to fix the lamp cup 211 and multiple optical elements, not only can the safety of the lamp cup and the optical elements installed inside the lamp cup be guaranteed, making them less susceptible to damage from impacts, but it also facilitates the alignment of the entire optical assembly 21 with the screen panel 22 and the reflector 23 in sequence during installation. At the same time, using aluminum alloy fittings made of the same material for the outer shell 11 and the mounting bracket 14 makes the overall structure more robust and lightweight. Combined with the heat dissipation fins provided on the outer side of the mounting bracket 14, the heat generated by the optical assembly 21 during operation can be dissipated more effectively.

[0059] Example 3

[0060] Please refer to Figure 1 , Figure 7 Based on Embodiment 1, the controller 30 has an operation panel 31, which is located on the top of the controller 30;

[0061] The operation panel 31 is provided with a switch button 32 and an indicator light 33. The switch button 32 is configured to control the opening or closing of the optical component 21, and the indicator light 33 is configured to indicate the opening or closing status of the optical component 21.

[0062] Alternatively, the operation panel 31 may be a touch screen configured to control the on or off state of the optical component 21.

[0063] By setting a switch button 32 and an indicator light 33 on the operation panel 31, or by using a touch screen as the operation panel 31, users can easily control the light source in the optical component 21 to turn on or off.

[0064] In one application scenario of this embodiment, a power supply interface 15 is provided on the headlight housing 10, and the power supply interface 15 is electrically connected to the controller 30;

[0065] The power supply interface 15 is located on the top or side of the headlight housing 10; the power supply interface 15 is a USB interface or a DC interface.

[0066] On the top of the headlight housing 10, a USB or DC interface is provided as a power supply interface 15, which facilitates direct power supply from the balance scooter power supply or external power supply such as (power bank, battery) to power the projection headlight. At the same time, the power supply interface 15 is more compatible with conventional power supply cables, eliminating the need for users to purchase additional power cables.

[0067] Example 4

[0068] Based on Embodiment 1, the third lens 16 is a prism used to shift the projected light spot of the headlight beam emitted from the third lens 16, or the third lens 16 is a beam expander used to magnify the projected light spot of the headlight beam emitted from the third lens 16.

[0069] In one application scenario of this embodiment, the sleeve 12 is rotatably mounted on the outer casing 11 via an adapter ring, so as to adjust the emission direction of the vehicle headlight beam from the emission port 13 by rotating the sleeve 12;

[0070] The angle between the reflector 23 and the optical path of the headlight beam is 45°.

[0071] Understandably, by using a prism as the third lens 16, the projection can be projected onto the inclined plane at an inclined angle; or, a beam expander can be used to magnify the projection and project it onto the plane; or, a lens group formed by a prism and a beam expander can be used as the third lens 16 to simultaneously achieve the purpose of magnification and inclined projection; thus, it is convenient to meet the projection needs of users in different situations.

[0072] Furthermore, by setting a rotatable adapter ring, when the headlight beam is aligned with the center of the reflector 23, the sleeve 12 is rotated to adjust the direction of the headlight beam emitted from the outlet 13. This allows the sleeve 12 to be freely rotated after the projection headlight is installed, enabling multi-angle projection and increasing the playability of the projection headlight during projection.

[0073] Example 5

[0074] Please refer to Figure 3 Based on Embodiment 1, the projection vehicle light also includes a wireless transceiver element 40, which is disposed on the inner wall of the vehicle light housing 10 and is electrically connected to the controller 30 or the screen panel 22.

[0075] The wireless transceiver element 40 can be any one of a WiFi module, a Bluetooth module, or a GPS receiver.

[0076] By using any one of a WiFi module, Bluetooth module, or GPS receiver as the wireless transceiver element 40, and by electrically connecting the wireless transceiver element 40, the controller 30, and the screen panel 22, the controller 30 can receive signals through the wireless transceiver element 40 and adjust the display content of the screen panel 22 after the user has selected and installed the wireless transceiver element 40.

[0077] Example 6

[0078] Please refer to Figures 6-7 In one embodiment of the present invention, the projection vehicle light further includes a mounting assembly 50, which includes a base 51 and a fixing bracket 52. A connector 53 is installed at the bottom of the fixing bracket 52, and the connector 53 is used to mount the fixing bracket 52 on the base 51. One side of the fixing bracket 52 is provided with an opening with an elastic buckle, and the vehicle light housing 10 is mounted on the fixing bracket 52 from the side of the elastic buckle.

[0079] In one application scenario of this embodiment, the connector 53 has an upper connecting plate and a lower connecting plate. The upper connecting plate is fixedly connected to the bottom of the fixed bracket 52 by screws, and the lower connecting plate is fixedly connected to the base 51 by screws.

[0080] In one application scenario of this embodiment, the fixing bracket 52 is made of plastic. After installation, the elastic deformation of the plastic material is used to clamp the headlight housing, thereby reducing the cost of production and manufacturing.

[0081] In this embodiment, the base 51 is fixedly installed in the forward or backward direction of the electric balance vehicle by adhesive or screws, so that the beam of the projection vehicle light can be directed in the forward or backward direction to achieve the lighting or projection effect in the corresponding direction. The fixing bracket 52 is used to fix the vehicle light housing to the mounting assembly by elastic snap-fit ​​and limiting to prevent accidental fall. At the same time, the base 51 and the fixing bracket 52 are detachably connected by the connector 53. After the lower connecting plate of the connector 53 is fixedly connected to the base 51 by screws, the installation direction of the fixing bracket 52 relative to the base 51 can be adjusted to achieve upright installation (with the opening of the elastic buckle facing upward) or inverted installation (with the opening of the elastic buckle facing upward, provided that the vehicle light housing is effectively fixed), thereby adjusting the height position of the vehicle light beam. This embodiment can easily install or remove the projection vehicle light, and flexibly adjust the height of the emitted beam of the projection vehicle light.
