[0046] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0047] Reference below Figure 1-Figure 13 The vehicle-mounted projection device, the projection system and the vehicle according to the embodiments of the utility model are described.

[0048] The vehicle-mounted projection device of the embodiment of the utility model comprises a bracket 1 and a projector 2 .

[0049] The bracket 1 is used to be arranged on a vehicle body. The bracket 1 includes a guide section 11 and a clamping section 12 sequentially arranged along the extension direction of the bracket 1. The clamping section 12 is provided with one of a clamping member 3 and a clamping slot 121. The projector 2 has a switchable clamping state and a guiding state. The projector 2 is provided with the other of the clamping member 3 and the clamping slot 121. The projector 2 and the guide section 11 guide and move to form the guiding state. In the clamping state, the clamping member 3 has a clamping tongue portion 311, and the clamping tongue portion 311 is clamped in the clamping slot 121 to form the clamping state. It can be understood that the clamping member 3 is connected to the projector 2, and the clamping slot 121 is arranged on the bracket 1; or the clamping slot 121 is arranged on the projector 2, and the clamping member 3 is arranged on the bracket 1.

[0050] The vehicle-mounted projection device of the embodiment of the utility model divides the bracket 1 into a guide section 11 and a clamping section 12 sequentially arranged along the extension direction thereof, and the projector 2 is guided and moved in cooperation with the guide section 11. During assembly, the projector 2 can be positioned first by the cooperation between the guide section 11 and the projector 2, and then the projector 2 can be clamped in the clamping section 12 without the need for manual positioning of the projector 2. Therefore, the vehicle-mounted projection device greatly improves the convenience of projector installation.

[0051] Therefore, the vehicle-mounted projection device according to the embodiment of the utility model has the advantage of high installation convenience.

[0052] The projector 2 has a switchable engagement state and a guide state, which can be specifically understood to be determined according to the relative matching state of the projector 2 and the bracket 1. When the projector 2 is installed, the projector 2 can be guided and moved with the help of the guide section 11, and the projector 2 can be positioned first by the matching between the guide section 11 and the projector 2. When the projector 2 is installed to the guide position, the tongue portion of the clamping member 3 is arranged in the clamping groove 121, thereby fixing the projector 2.

[0053] Optionally, the guide section 11 and the engaging section 12 may be a continuous guide rail section or two components arranged at intervals. Furthermore, corresponding indicator lights, sensors and electric controls may be arranged on the engaging section 12, and the indicator lights, sensors and electric controls are electrically connected. The sensor is arranged on the engaging section 12, so that after the projector 2 is pushed into the corresponding position of the engaging section 12, the indicator lights light up to indicate that the projector 2 is installed in place. Thus, the vehicle-mounted projection device further improves the convenience of installation.

[0054] For example, the bracket 1 includes a guide segment 11 and a clamping segment 12 arranged in sequence along its extension direction. For example, the guide segment 11 and the clamping segment 12 can be arranged in sequence along the front-rear direction of the vehicle body, and the guide segment 11 can be arranged at the front side of the clamping segment 12.

[0055] like Figure 1 , Figure 8 and Fig. 9 As shown, the holding member 3 includes a guide block 31, a pressing block 32 and an elastic member 33. The pressing block 32 has a limiting portion, and the guide block 31 has a tongue portion 311. The elastic member 33 is arranged between the guide block 31 and the limiting portion to press the guide block 31 in the direction of the tongue portion 311 extending into the slot 121. The pressing block 32 is used to squeeze the guide block 31 to overcome the elastic force of the elastic member 33 to drive the tongue portion 311 to disengage from the slot 121. In the guiding state, the tongue portion 311 abuts against the wall surface of the bracket 1. In the engaging state, the tongue portion 311 is clamped in the slot 121.

[0056] The vehicle-mounted projection device of the embodiment of the utility model is provided by dividing the clamping member 3 into a guide block 31, a pressing block 32 and an elastic member 33, and the pressing block 32 is used to press the guide block 31 to overcome the elastic force of the elastic member 33 to drive the tongue 311 to disengage from the clamping slot 121. Therefore, when the projector 2 is disassembled, the clamping member 3 can be disassembled by pressing the pressing block 32, thereby further improving the convenience of disassembling the projector 2.

[0057] Meanwhile, in the guiding state, the tongue portion 311 abuts against the wall surface of the bracket 1, and the elastic member 33 presses the guide block 31 to abut against the wall surface of the bracket 1. When the projector 2 is switched between the engaging state and the guiding state, the tongue portion 311 can be driven by the elastic force of the elastic member 33 to engage with the card slot 121. Thus, the vehicle-mounted projection device further improves the convenience of installation.

[0058] like Figure 1 and Figure 3 As shown, the projector 2 is provided with a guide groove 211 matching the guide section 11 , and a part of the guide section 11 is embedded in the guide groove 211 .

[0059] The vehicle-mounted projection device of the embodiment of the utility model embeds a part of the guide section 11 in the guide groove 211. Thus, a part of the guide section 11 can position the guide groove 211 of the projector 2, thereby further improving the convenience of installation.

[0060] like Figure 1 , Figure 8 and Fig. 9 As shown, the tongue portion 311 has an inclined surface 312, and the inclined surface 312 of the tongue portion 311 is inclined from the engaging section 12 to the guiding section 11 (for example, Figure 1 That is, in the guiding state, the tongue portion 311 abuts against the inclined surface 312 on one side of the guiding section 11 .

[0061] The vehicle-mounted projection device of the embodiment of the utility model is configured such that the inclined surface 312 of the tongue portion 311 is inclined from the engaging section 12 to the guiding section 11. When the projector 2 is guided and moved with the guiding section 11, the contact area between the inclined surface 312 of the tongue portion 311 and the guiding section 11 is relatively small, and the relative resistance is also small during the guided movement. Thus, the vehicle-mounted projection device helps to improve the convenience of installation.

[0062] like Figure 1 , Figure 8 and Fig. 9 As shown, the elastic member 33 has a first end and a second end that are arranged opposite to each other, the first end of the elastic member 33 stops on the guide block 31, and the second end of the elastic member 33 stops on the projector 2; a groove 313 is provided on the top surface of the guide block 31, and a first mounting column 215 is provided on the bottom surface of the groove 313, and a second mounting column 231 is provided on the inner wall of the projector 2, one end of the elastic member 33 is sleeved on the first mounting column 215, and the second end of the elastic member 33 is sleeved on the second mounting column 231.

[0063] The vehicle-mounted projection device of the embodiment of the utility model is provided with a first mounting column 215 on the guide block 31, and a second mounting column 231 is provided on the inner wall of the projector 2. When the elastic member 33 is installed, both ends of the elastic member 33 are clamped on the first mounting column 215 and the second mounting column 231. When the guide block 31 moves with the guide block 31, the guide block 31 can only move along the length direction of the mounting column, preventing the guide block 31 from moving out of position, thereby improving the stability of the movement process of the structure. Therefore, the vehicle-mounted projection device of the embodiment of the utility model has the function of preventing the guide block 31 from being difficult to reset during the process of pressing the pressing block 32.

[0064] Optionally, the elastic member 33 may be a compression spring.

[0065] like Figure 1 , Figure 8 and Fig. 9 As shown, the side surface of the guide block 31 is a first inclined surface 314 , and the side surface of the pressing block 32 that contacts the first side surface of the guide block 31 is a second inclined surface 321 .

[0066] The vehicle-mounted projection device of the embodiment of the utility model has the advantage of reducing the force required for pressing by setting the side surface of the pressing block 32 in contact with the first side surface of the guide block 31 as an inclined surface, so as to make the guiding movement of the guide block 31 more flexible.

[0067] like Figure 5 and Figure 7As shown, the projector 2 includes a housing 21 and a projector body 23 disposed in the housing 21. The housing 21 is provided with a placement groove and a control hole. The depth direction of the placement groove is perpendicular to the extension direction of the control hole. The pressing block 32 is inserted into the control hole. The two ends of the elastic member 33 in the length direction are respectively abutted against the bottom wall of the placement groove and the guide block 31. It can be understood that the card slot 121 is provided in the bracket 1.

[0068] The vehicle-mounted projection device of the embodiment of the utility model is divided into a shell 21 and a projector body 23 disposed in the shell 21, and the shell 21 is provided with a clamping member 3. Because the accommodation space on the shell 21 is larger than that on the bracket 1, the corresponding placement grooves and control holes are pre-opened on the shell 21 during processing, and the relative convenience of assembly is higher. Therefore, the vehicle-mounted projection device has the advantages of stable structure and convenient processing.

[0069] Specifically, for example, Fig. 9 As shown, the seating groove extends along the thickness direction of the housing 21 .
