Description

Technical Field

[0001] The present invention relates to the field of mechanical connection components, and particularly to a universal bracket with flexible angle adjustment. Background Art

[0002] In the installation and use of modern technological products, especially in-vehicle electronic products such as display screens and other components, a device that can stably support and conveniently adjust the angle is required. Although existing movable brackets can also achieve some purposes, after repeated or long-term use, due to wear, the fixed position cannot be well maintained, resulting in the inability to stably fix at the set position or angle, leading to fixation failure. Moreover, fixed brackets often have complex structures, large volumes, inconvenient installation, and poor flexibility in angle adjustment, making it difficult to meet the installation requirements of increasingly miniaturized and multifunctional electronic products. The present invention aims to provide a universal bracket with a simple structure, small size, and capable of flexible multi-angle adjustment and high reliability to solve the above problems. Summary of the Invention

[0003] The universal bracket of the present invention mainly includes three coaxially connected fixed seats, a connecting shaft, and a fastener, and each component cooperates with each other to achieve a unique function.

[0004] Specifically, a universal bracket includes a shaft fixed seat, a second fixed seat, a third fixed seat, a connecting shaft, and a fastener. The shaft fixed seat is bowl-shaped and is located inside the second fixed seat. A fixing hole is provided in the middle of the shaft fixed seat. The second fixed seat is located between the shaft fixed seat and the third fixed seat. The second fixed seat is bowl-shaped, and both the inner and outer circumferential surfaces are arc-shaped. The rim of the bowl extends outward to form a cap-shaped ring for fixing external parts. A movable hole for its own rotation is provided at the center of the bottom of the bowl. The third fixed seat is bowl-shaped and is adjacent to the outer circumferential surface of the second fixed seat. The rim of the bowl is lower than that of the second fixed seat, and a through hole is provided at the center of the bottom of the bowl. The hole positions at the centers of the fixed seats are coaxial. The connecting shaft passes through the coaxial hole positions to connect the shaft fixed seat, the second fixed seat, and the third fixed seat, and is fixed by a fastener.

[0005] Furthermore, the universal bracket further includes a thickening washer, which is located on the connecting shaft between the third fixed seat and the fastener.

[0006] Preferably, the connecting shaft is a hexagonal bolt.

[0007] Preferably, the middle part of the shaft fixed seat is a counterbore. The upper part of the counterbore is hexagonal, and the lower hole diameter is adapted to the connecting shaft.

[0008] Preferably, the fastener is a plum-shaped internal thread nut.

[0009] Further, through holes for fixing external parts are provided on the circular ring at the mouth of the second fixing seat bowl.

[0010] The present invention has at least the following beneficial effects: 1. Flexible angle adjustment: The second fixing seat is located between the shaft fixing seat and the third fixing seat, and is designed in a bowl shape. Both its inner and outer circumferences are designed as arc surfaces. This design of arc surface fitting with arc surface and bowl shape fitting with bowl shape enables the second fixing seat to rotate flexibly around the connecting shaft as the axis within the space defined by the shaft fixing seat and the third fixing seat after loosening the fastener, with small friction and smooth rotation.

[0011] 2. Simple and compact structure: Compared with the traditional complex bracket structure, the present invention greatly reduces the overall volume through a clever bowl-shaped design and component layout, and is more suitable for installation environments with limited space such as in vehicles.

[0012] 3. Strong fixing stability: By adjusting the fastener nut to maintain an appropriate pressing force between the shaft fixing seat and the third fixing seat to generate damping, the second fixing seat can be stably maintained at the current angle, and can still maintain a firm connection under vehicle conditions such as vibration and bump, with high reliability.

[0017] Combined with Figure 1-2 , the gimbal includes three coaxially connected fixing seats, a connecting shaft 4, and a fastener 5. The fixing seats include a shaft fixing seat 1, a second fixing seat 2, and a third fixing seat 3.

[0018] The second fixing seat 2 is located between the shaft fixing seat 1 and the third fixing seat 3. The second fixing seat is bowl-shaped, and both the inner and outer circumferential surfaces are arc-shaped, which can reduce the frictional resistance when adjusting the angle and achieve smoother rotation. The rim of the second fixing seat extends outward to form a brim-shaped ring, and holes for fixing external parts are also provided on the ring, which can conveniently use connecting parts such as bolts to firmly fix in-vehicle electronic products, such as components like display screens.

[0019] A moving hole for its own rotation is provided at the center of the bottom of the second fixing seat 2, such as Figure 2 , there is a relatively large gap between the moving hole at the center of the bottom of the second fixing seat 2 and the connecting shaft 4, and the gaps between the shaft fixing seat 1, the third fixing seat 3 and the shaft are relatively small. After loosening the fastener 5, the second fixing seat can rotate flexibly around the connecting shaft within the space defined by the shaft fixing seat and the third fixing seat to adjust the angle required by the external parts.

[0020] The shaft fixing seat 1 is bowl-shaped and is located inside the second fixing seat 2. A fixing hole is provided in the middle of the shaft fixing seat.

[0021] The third fixing seat 3 is also bowl-shaped and is adjacent to the outer circumferential surface of the second fixing seat. The rim of the bowl is lower than that of the second fixing seat, leaving enough space for the angle adjustment of the second fixing seat to avoid interference between components. A through hole is provided at the center of the bottom of the bowl, which is coaxial with the moving hole at the center of the bottom of the second fixing seat and the fixing hole in the middle of the shaft fixing seat to ensure that the connecting shaft can pass through smoothly.

[0022] The holes at the bottoms of the shaft fixing seat 1, the second fixing seat 2, and the third fixing seat 3 are coaxial. The connecting shaft 4 passes through the coaxial holes to connect the three fixing seats and is fixed by a fastener 5. The inner and outer circumferential surfaces of the second fixing seat 2 are both arc surfaces, and the outer circumferential surface of the shaft fixing seat that fits with the second fixing seat 2 and the inner circumferential surface of the third fixing seat are both arc surfaces. This design of the fit between arc surfaces and between bowl shapes enables the second fixing seat to rotate and adjust around the connecting shaft within the space defined by the shaft fixing seat and the third fixing seat when the fastener is loosened.

[0023] In one embodiment, the connecting shaft is a hexagon bolt. The central fixing hole of the shaft fixing seat is a counterbore. The upper part of the counterbore is hexagonal, matching the shape of the bolt head, and the lower hole diameter is adapted to the diameter of the connecting shaft. The head of the hexagon bolt sinks into the counterbore and is flush with the surface of the shaft fixing seat, which is convenient for installation and improves the overall aesthetics.

[0024] The fastener 5 is fixed to the tail of the connecting shaft. Tightening the fastener can fix the shaft fixing seat, the second fixing seat, and the third fixing seat. In a preferred embodiment, the fastener is a plum-shaped internal thread nut, which can provide a large torque and is convenient for adjusting the position of the fastener on the connecting shaft. The user can easily tighten or loosen the fastener.

[0025] In one embodiment, the universal bracket further includes a thickening washer, which is located on the connecting shaft between the third fixing seat and the fastener. The thickening washer plays a role in buffering and dispersing pressure, preventing the fastener from damaging the third fixing seat during the tightening process, and at the same time can further enhance the stability of the connection.

[0026] The second fixing seat is made of metal and has sufficient strength to support external components, ensuring no deformation under long-term use and different working conditions. The shaft fixing seat and the third fixing seat are made of plastic material, having a certain hardness and elasticity. On the one hand, they can provide a certain supporting force. On the other hand, when cooperating with the metal second fixing seat, their own elasticity makes the connection between the fixing seats tighter. After adjusting the fastener, the second fixing member can be pressed tightly, enabling the second fixing seat to be stably maintained at the current angle, avoiding loosening and abnormal noises, and at the same time reducing the weight of the entire bracket.

[0027] Combined Figure 3 , it is a schematic diagram of the connection state between the universal bracket and the in-vehicle display terminal. The display terminal is fixed to the brim-shaped ring of the second fixing seat through bolts and other connecting pieces. When the angle of the display screen needs to be adjusted, the user manually loosens the plum-shaped nut, adjusts the fixing angle of the display screen up and down, rotates the second fixing seat relative to the third fixing seat until the appropriate angle, and tightens the nut to fix the second fixing seat. The display screen can be stably fixed at the current angle and still maintain a firm connection under in-vehicle conditions such as vibration and bumpiness, with high reliability.
