Description

Technical Field

[0002] The car screen is a human-computer interaction interface installed in the car, which is used to display a lot of information such as car status, navigation information, communication information, etc.; conventional car screens are mostly installed in an inlaid manner, resulting in the inability to adjust the display angle, which brings a lot of inconvenience to the driver. For this reason, screen brackets with movable pairs have appeared on the market.

[0003] The existing screen bracket mainly includes a support arm and a wheel rod. The support arm is installed on the car. One end of the wheel rod is fixed to the screen through a mounting plate, and the other end is rotatably connected to the support arm so that the screen can swing. An interference fit is adopted between the wheel rod and the support arm to limit the wheel rod through friction, thereby ensuring that the screen can stay in the current position after swinging.

[0004] However, it was found in actual driving that the above structure has poor stability. Especially when the car passes through an uneven road, the vibration force generated will be directly transmitted to the wheel rod through the support arm, which will not only lead to a decrease in stability, but also cause a rigid collision between the wheel rod and the support arm, aggravating the wear of the wheel rod and the support arm and shortening the overall service life.

[0005] Therefore, it is urgent to design a new screen bracket to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See attached Figure 1 -Attached Figure 6 A high-stability vehicle-mounted screen adjustment bracket comprises a first supporting mechanism 1 and a mounting plate 2 for fixing a screen, wherein the first supporting mechanism 1 comprises a support arm 11, a wheel rod 12 and a buffer portion 13; a receiving cavity 110 is provided inside the support arm 11; the wheel rod 12 is arranged in the receiving cavity 110, and a rotating block 121 rotatably connected to the support arm 11 is provided at the head end of the wheel rod 12, and a connecting block 122 protruding from the receiving cavity 110 and connected to the mounting plate 2 is provided at the tail end of the wheel rod 12; the buffer portion 13 comprises a shaft sleeve 130, the shaft sleeve 130 is installed in the receiving cavity 110 and sleeved with the wheel rod 12, and two ends of the shaft sleeve 130 respectively abut against the rotating block 121 and the connecting block 122; a plurality of deformable friction blocks 1300 are arranged in a circular array on the shaft sleeve 130, and the plurality of friction blocks 1300 abut against each side wall of the wheel rod 12 at the same time.

[0036] Specifically, when in use, the support arm 11 of the first support mechanism 1 is installed on the center console of the car so that the screen faces the user.

[0037] When in use, the wheel rod 12 is rotated around the support arm 11 to drive the mounting plate 2 to swing, thereby adjusting the display angle of the screen. During this process, multiple friction blocks 1300 rub against the rotating wheel rod 12 to form damping, so that the rotated screen can stay in the current position when not subject to external force and can be used normally.

[0038] When the car passes through an uneven road or vibrates due to other reasons, the support arm 11 transmits the vibration force to the wheel rod 12, and the wheel rod 12 transmits the vibration force to the multiple friction blocks 1300, so that the multiple friction blocks 1300 will deform adaptively. The multiple deformed friction blocks 1300 have a buffering effect to eliminate the vibration force.

[0039] In summary, the utility model designs a receiving cavity 110 inside the support arm 11 for installing the wheel rod 12, and the wheel rod 12 is rotatably connected to the support arm 11 and connected to the mounting plate 2, so as to facilitate the adjustment of the rotation angle of the screen; by designing a sleeve 130 in the receiving cavity 110 for sleeve-mounting the wheel rod 12, and the multiple friction blocks 1300 on the wheel rod 12 can limit the wheel rod 12 and have damping, and because the multiple friction blocks 1300 can be deformed as the wheel rod 12 vibrates, the sleeve 130 also has a buffering effect, which can effectively eliminate the vibration force and improve the overall stability, and can also avoid the rigid collision between the wheel rod 12 and the support arm 11, and reduce the wear between the support arm 11, the wheel rod 12 and the sleeve 130, thereby extending the overall service life.

[0040] It should be noted that the sleeve 130 can be made of plastic, and by opening a plurality of spaced grooves on the sleeve 130, a plurality of friction blocks 1300 that are interference fit with the wheel rod 12 are formed, so that the plurality of friction blocks 1300 have a certain deformation ability and reset ability, ensuring that the plurality of friction blocks 1300 can be reused; in addition, the plurality of friction blocks 1300 can also be designed independently relative to the sleeve 130. In this case, the sleeve 130 can be made of any hard material, and the plurality of friction blocks 1300 are made of plastic or other materials with deformation and recovery capabilities. Due to the diversity of corresponding materials, there is no restriction on this in the utility model.

[0041] See attached Figure 6 -Attached Fig.10 The buffer portion 13 also includes two bearings 131 installed in the accommodating cavity 110. The two bearings 131 are sleeved on the wheel rod 12 and are respectively located on both sides of the sleeve 130. The sleeve 130 respectively abuts against the rotating block 121 and the connecting block 122 through the two bearings 131. The design of the two bearings 131 can further reduce the friction between the wheel rod 12 and the support arm 11, and improve the rotation stability of the wheel rod 12.

[0042] See attached Figure 6 -Attached Fig.10 Considering that the sleeve 130 and the bearing 131 are not installed tightly during the assembly process, and after long-term use, the connection between the bearing 131 and the sleeve 130 may wear and become loose, in order to solve this problem, in the utility model, the buffer part 13 also includes an elastic member 132, and a boss 1301 is provided on the sleeve 130, and the boss 1301 abuts against the bearing 131 close to the rotating block 121, and the elastic member 132 is sleeved on the sleeve 130 and abuts against the boss 1301 and the bearing 131 close to the connecting block 122 respectively.

[0043] Specifically, after assembly, the elastic member 132 applies pressure to the boss 1301 and the bearing 131 close to the connecting block 122 at the same time, so that the two bearings 131 fit tightly against the rotating block 121 and the connecting block 122, and when the connection between the sleeve 130 and the two bearings 131 is worn, the elasticity continues to apply pressure to the boss 1301 and the two bearings 131; therefore, the design of the elastic member 132 can effectively eliminate the installation gap, ensuring that the sleeve 130 and the two bearings 131 can remain tightly installed in the accommodating cavity 110, further extending the service life and overall stability.

[0044] Furthermore, there are various types of elastic members 132 , for example, rubber sleeves, springs, etc. For ease of understanding, the elastic member 132 in this embodiment is a spring, which has good deformation ability and can continuously apply pressure to the sleeve 130 and the two bearings 131 .

[0045] See attached Figure 6 -Attached Fig.10 The first support mechanism 1 also includes a driving member 14. A driving cavity 111 is also provided inside the support arm 11. The driving member 14 is installed in the driving cavity 111 and is drivingly connected to the rotating block 121. The driving member 14 drives the rotating block 121 to rotate, thereby driving the rotating rod and the mounting plate 2, thereby automatically adjusting the display angle of the screen.

[0046] Furthermore, there are various types of driving members 14. For ease of understanding, the driving member 14 in this embodiment includes a motor 141. The output shaft of the motor 141 is drivingly connected to the rotating block 121. By controlling the output shaft of the motor 141 to rotate forward or reverse, the wheel rod 12 can be driven to rotate forward or reverse, thereby adjusting the rotation angle of the screen.

[0047] See attached Figure 6 -Attached Fig.10 The driving member 14 also includes a reduction gear set 142, the input end of the reduction gear set 142 is connected to the output shaft of the motor 141, and the output end of the reduction gear set 142 is connected to the rotating block 121; the design of the reduction gear set 142 can slow down the rotation speed of the wheel rod 12 and improve the rotation stability of the wheel rod 12.

[0048] See attached Figure 1 -Attached Figure 3 The utility model also includes an end cover 3, which is mounted on the support arm 11 and encloses the rear end of the wheel rod 12. This design can prevent the wheel rod 12 from being exposed and improve the overall aesthetics.

[0049] See attached Figure 1 -Attached Figure 3 and attached Figure 7 The utility model also includes a control board 4 , which is installed in the end cover 3 and is electrically connected to the motor 141 .

[0050] Among them, the motor 141 and the reduction gear set 142 are both existing products, and the technology of controlling the operation of the motor 141 through the control board 4 is also relatively conventional in the technical field, so it is not elaborated in detail in the utility model.

[0051] See attached Figure 1 -Attached Figure 6 The utility model also includes a second supporting mechanism 5. The first supporting mechanism 1 is horizontally arranged, the second supporting mechanism 5 is vertically arranged and has the same structure as the first supporting mechanism 1, and the connecting block 122 of the second supporting mechanism 5 is fixedly connected to the support arm 11 of the first supporting mechanism 1.

[0052] Specifically, when in use, the arm 11 of the second supporting mechanism 5 is installed on the center console of the car, so that the first supporting mechanism 1 has a swing amplitude, and the screen has multiple adjustment angles to increase the adjustment flexibility of the screen.

[0053] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
