DETAILED DESCRIPTION

[0031] 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.

[0032] See attached Figure 1 -Attached Figure 6, a car screen flipping mechanism, comprising a support arm 1, a wheel rod 2, a spring 3 and a driving member 4; the support arm 1 is installed in a bracket (not shown in the figure), and a receiving cavity 10 is provided inside the support arm 1; the wheel rod 2 is rotatably installed on the support arm 1, and the head end of the wheel rod 2 can slide into the receiving cavity 10 and is installed with a pressure block 21, the tail end of the wheel rod 2 is placed outside the receiving cavity 10 and is provided with a connection portion 22 that abuts the support arm 1 and connects the screen P, and two wheel rods 2 are provided and symmetrically arranged at both ends of the support arm 1; the spring 3 is sleeved on the wheel rod 2 and abuts the pressure block 21 and the side wall of the receiving cavity 10, and two springs 3 are provided to correspond to the two wheel rods 2 one by one; the driving member 4 is installed in the receiving cavity 10, and the driving member 4 is connected to one of the wheel rods 2 to drive the wheel rod 2 to rotate to flip the screen P.

[0033] Specifically, when in use, the driving member 4 is started to drive the wheel rod 2 to rotate, so as to drive the screen P to flip, thereby adjusting the display angle of the screen P, and unfolding or retracting the screen P; and the elastic member can continuously apply pressure to the wheel rod 2 to make the wheel rod 2 have damping to prevent the screen P from moving too quickly, and during the rotation of the wheel rod 2, the elastic member can also undergo adaptive deformation, so it can also effectively reduce wear and tear to extend the service life.

[0034] In summary, the utility model installs the wheel rod 2 rotatably and slidably on the support arm 1 for connecting the screen P, and uses the elastic force of the elastic member itself to provide damping for the wheel rod 2. Compared with the method of using a damper, this structural design not only has a low cost, but also can reduce wear and tear and extend the service life; in addition, under the cooperation of the connecting part 22 and the elastic member, the wheel rod 2 does not have a tendency to move, so it can also well eliminate the installation gap of the wheel rod 2, thereby improving the installation stability of the wheel rod 2.

[0035] It should be noted that since the damping strength is related to the elastic force of the elastic member itself, if an elastic member with stronger elastic force is used, even if the elastic member is worn, the pressure value provided by the elastic member can still be within a certain range to maintain the damping required by the wheel rod 2, thereby further extending the overall service life.

[0036] See attached Figure 1 -Attached Figure 3 The connecting part 22 includes a main tooth block 221 and a secondary tooth block 222. The main tooth block 221 is installed at the tail end of the wheel rod 2 and abuts the support arm 1. The secondary tooth block 222 is installed on the screen P and meshed with the main tooth block 221. The secondary tooth block 222 is also provided with a shaft column 2220 rotatably connected to the bracket.

[0037] Specifically, when in use, the wheel rod 2 is driven to rotate by the driving member 4 , and the wheel rod 2 drives the main gear block 221 and the auxiliary gear block 222 , thereby causing the screen P to rotate in a circumferential direction around the shaft column 2220 .

[0038] It should be noted that, in addition to the above structure, the connecting portion 22 can also directly adopt a connecting plate (not shown in the figure), and fix the screen P through the connecting plate. In this case, there is no need to additionally set up the shaft column 2220, but the connecting plate and the screen P installed on the connecting plate are directly driven to rotate through the wheel rod 2.

[0039] See attached Figure 5 -Attached Figure 8 In order to facilitate the disassembly and assembly of the main tooth block 221, in the utility model, the connecting part 22 also includes a fastening bolt 223, and the main tooth block 221 is provided with a shaft sleeve 2210 on which the wheel rod 2 is sleeved, and the shaft sleeve 2210 is provided with a fastening hole 2211; the fastening bolt 223 is threadedly connected to the fastening hole 2211, and the end of the fastening bolt 223 can pass through the fastening hole 2211 and abut the wheel rod 2.

[0040] Specifically, when installing the main tooth block 221, screw the fastening bolt 223 into the fastening hole 2211 so that the end of the fastening bolt 223 abuts against the wheel rod 2, and the main tooth block 221 can be fixed to the rear end of the wheel rod 2; when removing the main tooth block 221, loosen the fastening bolt 223 to make it disengage from the fastening hole 2211.

[0041] See attached Figure 7 -Attached Fig.10 The elastic part can be a rubber column, an elastic plastic sleeve, a spring 3 and other accessories. For ease of understanding, the elastic part is taken as an example of a spring 3 in this embodiment; the spring 3 has the advantages of low cost, good elasticity, good deformation ability and recovery ability, and long service life.

[0042] See attached Figure 5 -Attached Fig.10 There are various types of driving members 4, which are not limited in the present invention. For ease of understanding, the driving member 4 in this embodiment includes a motor 41, and the output shaft of the motor 41 is drivingly connected to one of the wheel rods 2.

[0043] Specifically, by controlling the output shaft of the motor 41 to rotate forward or reverse, one of the wheel rods 2 can be driven to rotate. Since both wheel rods 2 are connected to the screen P through the connecting portion 22, the two wheels can rotate synchronously with the operation of the motor 41.

[0044] It should be noted that, if cost is not considered, two driving members 4 can also be provided to synchronously drive two wheel rods 2 to improve driving stability, and this is not limited in the present invention.

[0045] See attached Figure 6 -Attached Fig. 9 The driving member 4 also includes a speed reduction unit 42, which connects the output shaft of the motor 41 and the head end of the wheel rod 2; the design of the speed reduction unit 42 can slow down the rotation speed of the motor 41 driving the wheel rod 2 to improve the rotation stability of the wheel rod 2.

[0046] See attached Figure 6 -Attached Fig. 9 The types of the speed reduction part 42 are various and relatively conventional in the mechanical field, so the present invention does not impose any restrictions on this. For ease of understanding, the speed reduction part 42 in this embodiment includes a first gear 421, a second gear 422, a third gear 423, a gear column 424 and a speed reduction gear set 425; the first gear 421 is mounted on the output shaft of the motor 41 and is meshed with the second gear 422, the third gear 423 is mounted on the speed reduction gear set 425, the speed reduction gear set 425 is slidably connected to the head end of the wheel rod 2, the gear column 424 is rotatably mounted in the accommodating chamber 10, and the gear column 424 is meshed with the second gear 422 and the third gear 423 at the same time.

[0047] Specifically, when the output shaft of the motor 41 rotates, it will drive the first gear 421, and the first gear 421 will drive the tooth column 424 through the second gear 422, and the tooth column 424 will drive the reduction gear set 425 through the third gear 423, thereby driving the rotating rod to rotate; wherein, the first gear 421, the second gear 422, the third gear 423 and the tooth column 424 are used in coordination, have a transmission effect, and are convenient for installation in a closed space, and the reduction gear set 425 can slow down the rotation speed of the output shaft of the motor 41 to prevent the wheel rod 2 from rotating too fast; and since the reduction gear set 425 is slidably connected to the head end of the wheel rod 2, the reduction gear set 425 will not limit the movement of the wheel rod 2, ensuring that the elastic member can be normally squeezed by the pressure block 21 to play its role.

[0048] It should be noted that the reduction gear set 425 requires an existing product, so it is not further elaborated in the present invention.

[0049] See attached Figure 4 -Attached Figure 6 A bearing 23 is also provided at the rotation connection between the wheel rod 2 and the support arm 1. The bearing 23 is designed to support the wheel rod 2 and reduce the friction between the wheel rod 2 and the support arm 1, so as to improve the installation stability of the wheel rod 2 and reduce the wear of the wheel rod 2.

[0050] See attached Figure 1 -Attached Figure 4 The utility model also includes a mounting plate 5, which is fixed on the support arm 1, and is provided with a mounting hole 50 for inserting a bolt (not shown in the figure); the support arm 1 can be fixed on the bracket by connecting the bracket after the bolt passes through the mounting hole 50.

[0051] 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.
