Description

Technical Field

[0001] This utility model relates to the field of projection equipment technology, and in particular to a multi-angle adjustable vehicle projector mounting bracket. Background Technology

[0002] Currently, most vehicle projector mounting brackets use adjustable connection mechanisms to adapt to the vehicle seat environment. For example, as shown in patent number CN202222756064.7, an adjustable vehicle projector mounting bracket uses two sets of connection mechanisms and a linear adjustment mechanism on the back of the support plate to adjust the spacing of the connecting parts to adapt to the fixing groove spacing on the top of the vehicle seat, and uses a rotating shaft to adjust the angle of the projector.

[0003] However, in practice, it has been found that this type of structure only allows for single-degree-of-freedom adjustment via a rotation axis, which cannot meet the precise positioning requirements of projectors at multiple angles and in micro-positions, and can easily affect projection stability and user experience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing vehicle projector mounting brackets, which can only be adjusted in a single degree of freedom and therefore cannot meet the precise positioning requirements of projectors at multiple angles and in micro-directions. This invention proposes a multi-angle adjustable vehicle projector mounting bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a multi-angle adjustable vehicle projector mounting bracket, including a rotating bracket mechanism 1 and a universal ball mechanism 2 connected to the rotating bracket mechanism 1. The rotating bracket mechanism 1 is provided with a locking mechanism 3 to lock and position its rotation angle. The rotating bracket mechanism 1 is also provided with a connecting bracket 11 that is inserted into the car headrest mounting slot. The end of the universal ball mechanism 2 is provided with a connecting part 21 for connecting the projector and an adjusting nut 22 that cooperates with the connecting part 21 to adjust the torsional stroke of the projector.

[0007] Furthermore, the rotating support mechanism 1 includes a first rotating support 12 and a second rotating support 13 hinged to the first rotating support 12 via a horizontally arranged rotating shaft 14. The connecting support 11 is disposed on the first rotating support 12, and the universal ball mechanism 2 and the locking mechanism 3 are respectively disposed on the second rotating support 13.

[0008] Furthermore, the locking mechanism 3 includes a locking switch 31 and a fixing nut 32 disposed on the universal ball mechanism 2 and connected to the end of the locking switch 31. The lower end of the second rotating bracket 13 is provided with an opening 131 for the end of the locking switch 31 to be inserted therein.

[0009] Furthermore, the first rotating bracket 12 and the second rotating bracket 13 are arranged in pairs and connected accordingly by the rotating shaft 14. The openings 131 on the two second rotating brackets 13 overlap and allow the end of the locking switch 31 to be inserted.

[0010] Furthermore, the omnidirectional ball mechanism 2 includes an omnidirectional ball 23 and an omnidirectional ball mounting base 24. The omnidirectional ball mounting base 24 is provided with a ball socket 241 in which the omnidirectional ball 23 is rotatably mounted. The ball socket 241 is provided with a slot 242. The outer periphery of the omnidirectional ball mounting base 24 is provided with a locking member 25 that radially retracts the slot 242 to limit and lock the rotation of the omnidirectional ball 23. The connecting part 21 is provided on the end of the omnidirectional ball 23.

[0011] Furthermore, the locking component 25 includes a wrench 251 and a locking bolt 252 that engages with the end of the wrench 251. The outer periphery of the universal ball mounting base 24 is provided with a locking component mounting part 243. The locking component mounting part 243 has a through hole 244 for the end of the wrench 251 and the locking bolt 252 to pass through. The locking component mounting part 243 also has an opening 245 that communicates with the slot 242.

[0012] Furthermore, the connecting bracket 11 includes a first gasket 111 and an insertion part 112, the insertion part 112 being inserted into the car headrest mounting groove, and the first gasket 111 being disposed between the rotating bracket mechanism 1 and the insertion part 112.

[0013] Furthermore, the end of the omnidirectional ball mechanism 2 is provided with a second washer 26 disposed between the adjusting nut 22 and the projector.

[0014] The multi-angle adjustable vehicle projector mounting bracket proposed in this utility model has the following advantages:

[0015] In this utility model, the present application can adopt a two-level adjustment mode of large-angle coarse adjustment by rotating bracket mechanism and all-round fine adjustment by universal ball mechanism.

[0016] Secondly, in this utility model, the application can achieve non-destructive and rapid installation by utilizing the car's own structure. At the same time, it perfectly balances flexibility and stability through a two-stage adjustment and locking mechanism. Furthermore, it reduces costs and improves durability with a simple and reliable mechanical structure. It effectively solves the core pain points of the prior art, such as "inconvenient installation, cumbersome adjustment, and easy loosening". Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1 and Figure 2 As shown, a multi-angle adjustable vehicle projector mounting bracket includes a rotating bracket mechanism 1 and a universal ball joint mechanism 2 connected to the rotating bracket mechanism 1. The rotating bracket mechanism 1 provides rotational freedom in both horizontal and vertical directions, allowing for a wide range of angle adjustments to the projector. The universal ball joint mechanism 2 enables fine-tuning of the projector in any direction, including pitch, yaw, and roll. The rotating bracket mechanism 1 is equipped with a locking mechanism 3 to lock its rotation angle securely, preventing rotation due to vibration during vehicle operation. The rotating bracket mechanism 1 also includes a connecting bracket 11 that inserts into the car headrest mounting slot, serving as the interface between the entire bracket and the vehicle. This design allows for direct insertion into the car headrest mounting slot, enabling quick installation and removal. The end of the omnidirectional ball mechanism 2 is provided with a connecting part 21 for connecting the projector and an adjusting nut 22 that cooperates with the connecting part 21 to adjust the torsional stroke of the projector. After the omnidirectional ball mechanism 2 is locked, the adjusting nut 22 can provide a two-stage fine adjustment function, that is, by cooperating with the bolt of the connecting part 21, the projector can be tightened or loosened.

[0022] In this invention, a two-stage adjustment mode is employed: a rotating bracket mechanism 1 for coarse adjustment at large angles and a omnidirectional ball joint mechanism 2 for fine adjustment in all directions. Specifically, the rotating bracket mechanism 1 can quickly adjust the projector to the approximate desired direction and angle, while the omnidirectional ball joint mechanism 2 allows for fine adjustments in any direction (pitch, yaw, roll), ensuring the projected image is perfectly square and fills the screen without the need to repeatedly move the vehicle or the main bracket. This invention is intuitive to operate, with a clear two-stage adjustment logic, making it easy for users to learn.

[0023] In detail, in this embodiment, the present application can first adjust the spacing of the connecting bracket 11 according to the spacing between the support rods of the current car seat headrest using the rotating bracket mechanism 1, so as to directly insert the connecting bracket 11 into it. The rotating bracket mechanism 1 of the present application can adjust the spacing of the connecting bracket 11 so that it can adapt to each car model, with strong versatility and wide applicability. Then, the entire rotating bracket mechanism 1 can be manually rotated to adjust the left and right orientation and approximate pitch angle of the projector within a large range, and the locking mechanism 3 can be used to quickly lock it, realizing the first-level coarse adjustment. Next, the present application can use the swing universal ball mechanism 2 to fine adjust the projection angle of the projector in any direction (including up and down, left and right, and tilt). Finally, the adjusting nut 22 is used to perform the second-level fine adjustment to fix the projector on it, realizing the second-level fine adjustment.

[0024] In more detail, the design of the connecting bracket 11 in this application makes full use of the existing structure in the vehicle (headrest bar), allowing users to complete the installation or removal in seconds, greatly improving the user experience and achieving extremely simplified non-destructive installation. At the same time, it completely avoids the risk of leaving adhesive residue or damaging the vehicle interior by drilling, thus maintaining the integrity and resale value of the vehicle.

[0025] Clearly, this application enables non-destructive and rapid installation using the vehicle's own structure. Simultaneously, its two-stage adjustment and locking mechanism perfectly balances flexibility and stability, while its simple and reliable mechanical structure reduces costs and improves durability. It effectively solves the core pain points of existing technologies, such as inconvenient installation, cumbersome adjustment, and easy loosening, providing users with an optimized and reliable in-vehicle projection solution.

[0026] Furthermore, in this embodiment, as Figure 1 and Figure 2As shown, the rotating support mechanism 1 includes a first rotating support 12 and a second rotating support 13 hinged to the first rotating support 12 via a horizontally arranged rotating shaft 14. A connecting support 11 is mounted on the first rotating support 12. The rotating shaft 14 provides a pivot for a first degree of freedom of rotation, such as longitudinal angle adjustment. It connects the first rotating support 12 and the second rotating support 13, allowing relative rotation between them. It also adjusts the spacing between the connecting supports 11 to fit the current car headrest mounting slot. A ball joint mechanism 2 and a locking mechanism 3 are respectively mounted on the second rotating support 13. The second rotating support 13 provides a pivot for a second degree of freedom of rotation, such as lateral angle adjustment, thereby adjusting the projector's horizontal and vertical range. After the user has adjusted the approximate angle, the locking mechanism 3 can be used to stop the relative movement between the first and second rotating supports, ensuring the stability of the initial adjustment. Subsequently, the ball joint mechanism 2 can perform fine-tuning in all directions—up and down, left and right, and tilt—to precisely align the projected image.

[0027] Furthermore, in this embodiment, as Figure 1 and Figure 2 As shown, the locking mechanism 3 includes a locking switch 31 and a fixing nut 32 that is mounted on the universal ball mechanism 2 and connected to the end of the locking switch 31. The lower end of the second rotating bracket 13 is provided with an opening 131 for the end of the locking switch 31 to be inserted therein. This application allows the screw of the locking switch 31 to "penetrate" the bracket overlapping area, i.e., the opening 131, to form a through-type locking, preventing the second rotating bracket 13 from shifting laterally, and achieving the purpose of double-stage locking of the second rotating bracket 13 and the universal ball mechanism 2 with one tightening.

[0028] In detail, after the screw of the locking switch 31 passes through the opening 131 on the second rotating bracket 13, it is not yet connected to the internal thread of the fixing nut 32. At this time, the second rotating bracket 13 can be freely adjusted. Subsequently, after the second rotating bracket 13 has completed the angle adjustment, the locking switch 31 can be rotated clockwise so that the head of the screw of the locking switch 31 is tightly connected to the fixing nut 32, so as to fasten the universal ball mechanism 2 to the second rotating bracket 13. At the same time, the second rotating bracket 13 can be pressed at the same time to achieve locking.

[0029] Furthermore, in this embodiment, as Figure 1 and Figure 2As shown, the first rotating bracket 12 and the second rotating bracket 13 are arranged in pairs and connected by a rotating shaft 14. The openings 131 on the two second rotating brackets 13 overlap to allow the end of the locking switch 31 to be inserted. The paired first rotating brackets 12 provide double-sided support for pitch adjustment, resisting torsion and preventing off-center loading. The lower ends of the two second rotating brackets 13 overlap to form a "shared force-bearing surface," turning the locking force into a closed force ring. At the same time, the two holes at the lower ends of the second rotating brackets 13 completely overlap, allowing the locking switch 31 to pass through in one go, realizing "single-point locking of double brackets." The rotating shaft 14 can be hinged one-to-one, so that the first rotating brackets 12 and the second rotating brackets 13 rotate synchronously, ensuring that the angle adjustment is coaxial and without jamming.

[0030] In detail, firstly, the locking switch 31 can be loosened counterclockwise to release its tension on the two second rotating brackets 13. At this time, the whole assembly of the two second rotating brackets can rotate freely around the pivot 14 for coarse adjustment of the pitch angle. At this time, the universal ball mechanism 2 can also move freely for fine adjustment in all directions. After adjusting to the appropriate angle, the locking switch 31 is tightened clockwise. At this time, the thread at the end of the locking switch 31 can engage with the fixing nut 32, generating a strong pulling force. This pulling force, through the overlapping opening 131, simultaneously pulls the lower ends of the two second rotating brackets 13 closer to the central universal ball mechanism to lock the rotation angle of the second rotating brackets 13. At the same time, the same pulling force can directly act on the outer shell of the universal ball mechanism 2 to fix it to the second rotating brackets 13.

[0031] Furthermore, in this embodiment, as Figure 1 and Figure 2 As shown, the omnidirectional ball mechanism 2 includes an omnidirectional ball 23 and an omnidirectional ball mounting base 24. The omnidirectional ball mounting base 24 is provided with a ball socket 241 in which the omnidirectional ball 23 is rotatably mounted. It can accommodate and constrain the omnidirectional ball, providing it with a track and space for rotation and sliding. The omnidirectional ball 23 serves as the core angle adjustment mechanism. It can achieve flexible adjustment of the projector in multiple directions and angles by rotating the ball in the ball socket 241. The ball socket 241 is provided with a slot 242 to create a controllable weak point or elastic deformation area. The outer periphery of the omnidirectional ball mounting base 24 is provided with a locking member 25 for limiting and locking the rotation of the omnidirectional ball 23 by radially contracting the slot 242. The locking member 25 serves as a locking actuator. It can retract the slot 242 by applying external force (such as tightening a bolt). The connecting part 21 is provided at the end of the omnidirectional ball 23.

[0032] In detail, the omnidirectional ball 23 can rotate freely within the ball socket 241 to quickly align the projector with the screen. Then, the locking member 25 radially compresses the slot 242, reducing the inner diameter of the ball socket 241 and locking the omnidirectional ball 23 around its circumference, achieving stepless locking. Finally, after keeping the omnidirectional ball 23 stationary, only the adjusting nut 22 needs to be rotated to compensate for millimeter-level torsional movement of the projector using thread displacement, achieving precise focus or image edge alignment. If readjustment is needed, simply loosen the limiting member in the opposite direction to repeat the above steps. The entire process requires no disassembly of any parts, and the operation is completed in one step. This application, by adopting a universal thread or quick-release interface, combined with a one-handed locking member and adjusting nut, achieves a four-step integrated process of "installation-adjustment-locking-micro-adjustment," significantly improving installation and maintenance efficiency.

[0033] In more detail, this application employs a combination design of a ball socket 241 with a slotted structure 242 and a locking element 25. By operating the locking element 25 (such as tightening a bolt), the ball socket 241 can radially contract, thus uniformly gripping the universal ball like a "hand." This structure differs from traditional complex methods that use gears, racks, levers, or multiple bolts for tightening, achieving single-action control and multi-directional synchronous locking. This is a more direct and efficient force transmission method, with a simple structure, large and uniform locking force, and extremely high reliability.

[0034] Furthermore, in this embodiment, as Figure 1 and Figure 2 As shown, the locking component 25 includes a wrench 251 and a locking bolt 252 that engages with the end of the wrench 251. The locking bolt 252 can convert the torque of the wrench 251 into axial tension to radially tighten the ball socket 241 and lock the universal ball 23. The universal ball mounting base 24 has a locking component mounting part 243 on its outer periphery. It is a specially designed boss or reinforcing part on the universal ball mounting base 24, forming an independent force island and providing a sufficiently thick structure to process the through hole 244 and the opening 245, so as to avoid the locking force from damaging the roundness of the ball socket. The locking component mounting part 243 has a through hole 244 through which the end of the wrench 251 and the locking bolt 252 pass, providing precise guidance for the locking bolt 252 and ensuring that the direction of the tightening force is perpendicular to the slot each time. The locking component mounting part 243 also has an opening 245 communicating with the slot 242, ensuring that the force applied by the user is accurately transmitted to the slot 242 where deformation needs to occur without any waste, which is extremely efficient.

[0035] In detail, when the user rotates the wrench 251 counterclockwise, the pressure applied by the locking bolt 252 to the locking mounting part 243 is released. Due to the elasticity of the metal, the material on both sides of the slot 242 rebounds, the ball socket 241 returns to its original diameter, and the universal ball 23 returns to its free rotation state. After the user adjusts the projector angle, the wrench 251 can be rotated clockwise to drive the locking bolt 252 to apply pressure to the locking mounting part 243, causing the opening 245 to elastically deform and shrink inward. This results in the slot 242 becoming narrower, and the narrowing of the slot 242 inevitably causes the inner diameter of the ball socket 241 surrounding it to shrink, thus tightly gripping the internal universal ball 23 like a hand, eliminating all gaps and achieving absolute locking.

[0036] Furthermore, in this embodiment, as Figure 2 As shown, the connecting bracket 11 includes a first gasket 111 and an insertion part 112. The insertion part 112 is inserted into the car headrest mounting groove. The first gasket 111 is disposed between the rotating bracket mechanism 1 and the insertion part 112. The first gasket 111 is sandwiched between the rotating bracket mechanism 1 and the insertion part 112, which can compensate for manufacturing tolerances, increase friction, absorb driving vibration, and prevent the bracket from loosening and shaking.

[0037] Furthermore, in this embodiment, as Figure 2 As shown, the end of the omnidirectional ball mechanism 2 is provided with a second washer 26 positioned between the adjusting nut 22 and the projector. The second washer 26 acts as a protective and force distribution element, preventing the metal adjusting nut 22 from directly contacting and scratching or abrading the surface of the projector's casing. Furthermore, it can evenly distribute the concentrated force applied by the adjusting nut 22 over a larger area of ​​the projector casing, avoiding excessive local pressure that could cause deformation or damage to the casing.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
