Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or the order in which the indicated technical features are presented.

[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] In related technologies, after drivers arrive at outdoor parking locations, passengers often project their phones onto the vehicle's in-car screen for audio-visual playback. Projecting a phone screen to the vehicle's in-car screen essentially connects it to the central control screen, allowing playback of videos from the phone. To meet the viewing needs of passengers, a screen amplifier is typically installed on the in-car screen to magnify the image. However, the screen amplifier's installation position is not adjustable, making it inconvenient for users.

[0023] Reference Figures 1 to 3 An embodiment of the present invention discloses a vehicle-mounted projection device for a vehicle's in-vehicle screen, comprising a connecting frame 100, a screen amplifier 200, a mounting assembly, a telescopic assembly 400, and a damping adjustment assembly 500. The connecting frame 100 is connected to the in-vehicle screen, the screen amplifier 200 is mounted on the mounting assembly, and the telescopic assembly 400 includes a first rod 410 and a second rod 420. One end of the first rod 410 is connected to the connecting frame 100, and the second rod 420 is disposed on the first rod 410 and movable along the length direction of the first rod 410. The second rod 420 is located away from the first rod 410. The end connection mounting assembly includes a damping adjustment assembly 500 located between the first rod 410 and the second rod 420. The damping adjustment assembly 500 is used to adjust the moving resistance of the second rod 420. On the one hand, the telescopic assembly 400 allows the screen amplifier 200 to be adjusted along the length of the first rod 410, which can meet the viewing needs at different distances. On the other hand, by adjusting the moving resistance of the second rod 420, the damping adjustment assembly 500 enables the screen amplifier 200 to maintain a stable position after adjustment, thereby improving the ease of use and stability of the vehicle projection device.

[0024] For example, taking the front-to-back direction of the vehicle as the front-to-back direction of the in-vehicle projection device, the connecting frame 100 is located in front of the mounting component, and the second rod 420 can extend and retract relative to the first rod 410 in the front-to-back direction, so that the screen amplifier 200 can move relative to the in-vehicle screen in the front-to-back direction, which can meet the viewing needs of different distances. Moreover, the damping adjustment component 500 adjusts the moving resistance of the second rod 420, so that the screen amplifier 200 can maintain a stable position after adjustment, thereby improving the ease of use and stability of the in-vehicle projection device.

[0025] It should be noted that the screen amplifier 200 uses the principle of mirror optical refraction to magnify the originally slightly smaller in-vehicle screen, so as to achieve a wider field of view. It can magnify the image on the in-vehicle screen, and there are no limitations on this.

[0026] Reference Figure 3In this embodiment, the damping adjustment assembly 500 includes a housing 510, an abutment 520, an adjustment member 530, and an elastic member 540. The housing 510 is connected to the first rod 410. The abutment 520 and the adjustment member 530 are movably disposed on the housing 510. The moving directions of the abutment 520 and the adjustment member 530 are staggered. The adjustment member 530 is provided with a first inclined surface 531, and one end of the abutment 520 is provided with a second inclined surface 521. The first inclined surface 531 abuts against the second inclined surface 540. 21, so that the end of the abutment 520 away from the adjusting member 530 abuts against the second rod 420. The elastic member 540 is connected between the housing 510 and the adjusting member 530. The elastic member 540 is used to move the adjusting member 530 in the direction close to the abutment 520. The elastic member 540 can drive the adjusting member 530 to automatically reset so that the first inclined surface 531 continuously abuts against the second inclined surface 521, ensuring that the abutment 520 can stably abut against the second rod 420, thereby restricting the movement of the second rod 420.

[0027] For example, the adjusting member 530 can move vertically, and the abutting member 520 can move horizontally. When it is necessary to adjust the front and back position of the screen amplifier 200, the user can pull the adjusting member 530 away from the abutting member 520 to separate the first inclined surface 531 from the second inclined surface 521. At this time, the elastic member 540 is compressed, and the adjusting member 530 does not apply pressure to the abutting member 520. The friction between the abutting member 520 and the second rod 420 is reduced, which makes it easier for the user to move the screen amplifier 200. When the screen amplifier 200 is moved to the appropriate position, the adjusting member 530 is released. Under the elastic action of the elastic member 540, the adjusting member 530 automatically rebounds, so that the first inclined surface 531 continues to abut against the second inclined surface 521. This increases the friction between the abutting member 520 and the second rod 420, ensuring that the abutting member 520 can stably abut against the second rod 420, thereby restricting the movement of the second rod 420 and improving the reliability of the vehicle projection device.

[0028] It should be noted that there are two of each of the adjusting member 530 and the elastic member 540. One of the two adjusting members 530 is located above the abutment member 520, and the other is located below the abutment member 520. The second inclined surface 521 is a conical surface structure. The elastic member 540 is located between the corresponding adjusting member 530 and the housing 510. The first inclined surface 531 of the upper adjusting member 530 abuts against the upper side of the second inclined surface 521, and the first inclined surface 531 of the lower adjusting member 530 abuts against the lower side of the second inclined surface 521. When it is necessary to adjust the front and back position of the screen amplifier 200, the user's hand simultaneously pulls the upper adjusting member 530 upward and the lower adjusting member 530 downward to balance the force on the housing 510 and ensure that the first rod 410 is balanced. This can reduce the shaking of the first rod 410 and improve the reliability of the vehicle projection device. No restrictions are imposed here.

[0029] It should be noted that the elastic element 540 is a component that can undergo axial elastic deformation, such as a compression spring or a rubber component. The two ends of the elastic element 540 abut against the inner peripheral wall of the housing 510 and the adjusting element 530, respectively, without limitation.

[0030] It should be noted that the housing 510 has an internal cavity 511, and the upper and lower sides of the housing 510 are respectively provided with first openings 512, and the left or right side of the housing 510 is provided with a second opening 513. The adjusting member 530 enters the cavity 511 through the corresponding first opening 512, and the abutting member 520 enters the cavity 511 through the second opening 513, so that the first inclined surface 531 and the second inclined surface 521 can be hidden in the cavity 511, which can prevent dust from entering the mating position between the first inclined surface 531 and the second inclined surface 521, thereby improving the service life of the damping adjustment assembly 500.

[0031] In another embodiment, the damping adjustment assembly 500 includes a housing 510 and an abutment 520. The abutment 520 is threadedly connected to the housing 510. When the abutment 520 rotates, it can move in a direction close to or away from the second rod 420. One end of the abutment 520 abuts against the second rod 420, and can also adjust the moving resistance of the second rod 420. This is not limited here.

[0032] In this embodiment, the abutment 520 includes a main body 522 and a first magnet 523. A second inclined surface 521 is provided at one end of the main body 522, and the first magnet 523 is connected to the other end of the main body 522. The first magnet 523 magnetically attracts and abuts against the second rod 420, which can prevent the second rod 420 from moving relative to the first rod 410, thereby improving the stability of the screen amplifier 200 in its position.

[0033] For example, the second rod 420 is made of metal, and the first magnet 523 can attract the second rod 420, preventing the second rod 420 from moving relative to the first rod 410, thereby improving the stability of the screen amplifier 200 in its position.

[0034] Reference Figure 1 , Figure 7 In this embodiment, two telescopic components 400 are configured, and the two telescopic components 400 are arranged opposite to each other. The connecting frame 100 is provided with connecting shafts 101 arranged opposite to each other along the length direction of the vehicle screen. One end of the first rod 410 is rotatably connected to the corresponding connecting shaft 101 so that the vehicle projection device can be in a storage state or a use state. A locking structure is provided between the first rod 410 and the connecting shaft 101. The locking structure is used to restrict the vehicle projection device from switching from the use state to the storage state. On the one hand, by setting the locking structure and the two telescopic components 400, the stability of the screen amplifier 200 in the use state can be improved. On the other hand, when the vehicle projection device is not in use, the first rod 410 can be rotated to switch from the use state to the storage state, which can reduce the overall size of the vehicle projection device and make it convenient for users to store and fold the vehicle projection device.

[0035] For example, when the vehicle-mounted projection device switches from the use state to the storage state, the locking structure is disengaged, and the first rod 410 is rotated upwards to allow the connecting frame 100 to retract with the first rod 410, thereby reducing the overall size of the vehicle-mounted projection device and making it easier for users to store and store it. When the vehicle-mounted projection device switches from the storage state to the use state, the first rod 410 is rotated downwards to allow the first rod 410 to unfold relative to the connecting frame 100. Once the first rod 410 has moved to a preset position, it is connected and fixed by the locking structure. Then, the installation components are moved by the two telescopic components 400, which can improve the stability of the screen amplifier 200 in the use state.

[0036] In this embodiment, the locking structure includes a first fastener 103 and a plurality of threaded holes 102 provided on the connecting shaft 101. The plurality of threaded holes 102 are spaced apart along the circumference of the connecting shaft 101. The first fastener 103 passes through the first rod 410 and is threadedly engaged with the corresponding threaded hole 102. By selecting threaded holes 102 with different angles for fixing, the rotation angle of the first rod 410 can be adjusted in multiple positions and firmly locked, which can meet the viewing needs of users at different angles.

[0037] Reference Figure 2 In this embodiment, a second magnet 140 is provided on the side of the connecting frame 100 facing the mounting component. When the vehicle projection device is in the storage state, the second magnet 140 magnetically attracts the first rod 410, so that the vehicle projection device remains stable in the storage state, making it convenient for users to store the vehicle projection device.

[0038] For example, the first rod 410 is made of metal. When the vehicle projection device needs to be stored, the user can loosen the first fastener 103 so that the user can rotate the first rod 410 upward so that the first rod 410 contacts the second magnet 140, so that the vehicle projection device remains stable in the stored state, making it convenient for the user to store the vehicle projection device.

[0039] Reference Figures 3 to 5 In this embodiment, the mounting assembly includes a base 310, a first slide 320, a second slide 330, a third side plate 340, a fourth side plate 350, and an adjustment assembly. The base 310 is connected to the second rod 420. The first slide 320 and the second slide 330 are movably mounted on the base 310. The adjustment assembly is located on the base 310 and is used to move the first slide 320 and the second slide 330 closer to or further apart from each other. The third side plate 340 is connected to the first slide 320, and the fourth side plate 350 is connected to the second slide 330. The third side plate 340, the fourth side plate 350, and the base 310 together form a mounting groove. The screen amplifier 200 is mounted in the mounting groove. On the one hand, the third side plate 340 and the fourth side plate 350 can clamp and fix the screen amplifier 200. On the other hand, they can adapt to screen amplifiers 200 of different sizes, thereby improving the versatility of the vehicle projection device.

[0040] For example, when installing the screen amplifier 200, it is installed in the mounting slot. The first slide 320 and the second slide 330 are driven closer together by the adjusting component, so that the third side plate 340 and the fourth side plate 350 respectively abut against the left and right sides of the screen amplifier 200, improving the installation stability of the screen amplifier 200. When disassembling the screen amplifier 200, the first slide 320 and the second slide 330 are driven further apart by the adjusting component, so that the third side plate 340 and the fourth side plate 350 are separated from the screen amplifier 200, facilitating the installation and removal of the screen amplifier 200. Furthermore, since the third side plate 340 and the fourth side plate 350 can move closer or further apart, they can accommodate screen amplifiers 200 of different sizes, thereby improving the versatility of the vehicle-mounted projection device.

[0041] It is understandable that when the distance between the screen amplifier 200 and the connecting frame 100 increases, the magnification ratio of the image on the vehicle screen by the screen amplifier 200 increases. Users can improve their viewing experience by selecting a larger screen amplifier 200 so that the image on the vehicle screen can be fully displayed within the screen amplifier 200. No restrictions are imposed here.

[0042] Reference Figure 5 , Figure 6In this embodiment, the third side plate 340 is detachably connected to the first slide block 320. The third side plate 340 is provided with a first insertion post 342, and the first slide block 320 is provided with a first insertion hole. The first insertion post 342 is inserted into the first insertion hole and abuts against the side wall of the first insertion hole. The fourth side plate 350 is detachably connected to the second slide block 330. The fourth side plate 350 is provided with a second insertion post 352, and the second slide block 330 is provided with a second insertion hole. The second insertion post 352 is inserted into the second insertion hole and abuts against the side wall of the second insertion hole, so as to facilitate the user to store the vehicle projection device.

[0043] Reference Figure 6 In this embodiment, the third side plate 340 is provided with a first limiting groove 341 on the side facing the fourth side plate 350, and the fourth side plate 350 is provided with a second limiting groove 351 on the side facing the third side plate 340. The left and right sides of the screen amplifier 200 are respectively embedded in the first limiting groove 341 and the second limiting groove 351, and the screen amplifier 200 abuts against the side wall of the first limiting groove 341 and the side wall of the second limiting groove 351, which can improve the installation stability of the screen amplifier 200.

[0044] In this embodiment, the adjustment assembly includes a transmission rod 360 and a knob 370. The two ends of the transmission rod 360 along its length are respectively provided with a first threaded portion 361 and a second threaded portion 362. The helical direction of the first threaded portion 361 is opposite to that of the second threaded portion 362. The first slide 320 is threadedly engaged with the first threaded portion 361, and the second slide 330 is threadedly engaged with the second threaded portion 362. A transmission structure is provided between the knob 370 and the transmission rod 360. The knob 370 drives the transmission rod 360 to rotate through the transmission structure, which can realize the synchronous movement of the third side plate 340 and the fourth side plate 350, thereby improving the installation stability of the screen amplifier 200.

[0045] For example, the first slide 320 is sleeved on the outer periphery of the first threaded portion 361 and threadedly engaged with the first threaded portion 361, and the second slide 330 is sleeved on the outer periphery of the second threaded portion 362 and threadedly engaged with the second threaded portion 362. Since the helical direction of the first threaded portion 361 is opposite to that of the second threaded portion 362, when the adjusting component drives the transmission rod 360 to rotate through the transmission structure, the first slide 320 and the second slide 330 can move closer or further away from each other, which can realize the synchronous movement of the third side plate 340 and the fourth side plate 350, and improve the installation stability of the screen amplifier 200.

[0046] In another embodiment, the adjustment assembly includes a first rack, a second rack, and a first gear. The first rack is connected to the first slide 320, the second rack is connected to the second slide 330, and the first gear is rotatably connected to the base 310. The opposite sides of the first gear mesh with the first rack and the second rack respectively, which can also realize the synchronous movement of the third side plate 340 and the fourth side plate 350, which is not limited here.

[0047] In this embodiment, the transmission structure includes a first bevel gear 363 disposed on the transmission rod 360 and a second bevel gear 371 disposed on the knob 370. The first bevel gear 363 meshes with the second bevel gear 371, allowing the arrangement direction of the knob 370 to be perpendicular to the axial direction of the transmission rod 360, so that the knob 370 can be set in a more convenient position for operation, making it convenient for users to use.

[0048] In another embodiment, the transmission structure includes a second gear and a third gear. The second gear is located on the transmission rod 360, and the third gear is rotatably located on the base 310. The second gear meshes with the third gear and can also drive the transmission rod 360 to rotate. This is not limited here.

[0049] Reference Figure 2 In this embodiment, the connecting frame 100 includes a first side plate 110, a second side plate 120, and a connecting plate 130. The first side plate 110 and the second side plate 120 are disposed opposite to each other, and the connecting plate 130 is connected between the first side plate 110 and the second side plate 120. The first side plate 110 and the second side plate 120 are respectively provided with connecting shafts 101. The first side plate 110 is threadedly connected to a second fastener 104, which can move towards or away from the second side plate 120. The second side plate 120 is threadedly connected to a third fastener 105, which can move towards or away from the first side plate 110. The second fastener 104 and the third fastener 105 can apply clamping force from both sides simultaneously to ensure that the connecting frame 100 and the vehicle screen can achieve a stable connection, thereby improving the reliability of the vehicle projection device.
