Description

Technical Field

[0001] This utility model relates to the field of rotating mechanism technology, and in particular to a flipping mechanism and a flipping screen. Background Technology

[0002] Existing displays are typically connected to their bases via hinges, allowing the display to rotate. A hinge connection uses a mechanical device that can rotate around a fixed axis to connect the display to the base. This connection method allows the display to rotate within a certain range, adjusting its angle and position to meet different user needs. This connection method is widely used in laptops, monitor stands, and various electronic devices with displays.

[0003] Our company has designed another flipping mechanism that enables relative rotation of two components. Utility Model Content

[0004] The purpose of this utility model is to provide a flipping mechanism and a flipping screen. When the first connecting member and the second connecting member rotate relative to each other, the elastic member is squeezed from both ends to compress the elastic member, thereby enabling the first tooth and the second tooth to rotate, and thus enabling the component A connected to the first connecting member to rotate relative to the component B connected to the second connecting member.

[0005] This utility model is achieved through the following technical solution:

[0006] A flipping mechanism that causes component A to rotate relative to component B includes:

[0007] Elastic components;

[0008] The first connector, two first connectors are respectively fixedly connected to the two ends of the elastic member, and the end of the first connector away from the elastic member is provided with a first tooth;

[0009] The second connectors are respectively disposed on both sides of the first connector away from the elastic member. The second connectors have second teeth, and the teeth of the first teeth and the second teeth interlock and mesh.

[0010] Component A is connected to two first connecting members, and component B is connected to two second connecting members, and axially limits the ends of the second connecting members that are away from the first connecting members.

[0011] Furthermore, the center lines of both the first and second teeth coincide with the axis of the elastic element.

[0012] Furthermore, the elastic element is a helical spring.

[0013] Furthermore, the first connector has a guide portion at one end facing the helical spring, and the guide portion extends into the interior of the helical spring; the length of the guide portion is less than the initial length of the helical spring.

[0014] A flip screen includes the flipping mechanism described above, and also includes a screen assembly and a base assembly, wherein the screen assembly and the base assembly are connected through the flipping mechanism.

[0015] Furthermore, the screen assembly is connected to one of the two first connectors and the two second connectors, and the screen assembly and the connector cannot rotate relative to each other at least in the screen assembly flipping direction;

[0016] The base assembly is connected to the other of the two first connectors and the two second connectors, and the base assembly and the connector cannot rotate relative to each other at least in the screen assembly flipping direction;

[0017] The screen assembly or the base assembly connected to the second connector limits the second connector in the axial direction.

[0018] Furthermore, a limiting portion is provided on the outer periphery of the first connector, and a sleeve that fits against the limiting portion is provided on the screen assembly or base assembly connected to the first connector, so that when the sleeve is fitted on the limiting portion, the screen assembly or base assembly connected to the first connector cannot rotate relative to the first connector in the circumferential direction.

[0019] Furthermore, the end of the second connector away from the elastic member is a snap-fit ​​groove, and the screen assembly or base assembly connected to the second connector is provided with a protruding rib that matches the snap-fit ​​groove.

[0020] Furthermore, the base assembly includes an adjacent first plane and a second plane, the angle between the first plane and the second plane is greater than 180 degrees, and the flipping mechanism is disposed at the intersection of the first plane and the second plane.

[0021] Compared with the prior art, the technical solution of this utility model and its beneficial effects are as follows:

[0022] (1) When the flipping mechanism of this utility model is used, its two ends of the axis are limited. When component A and component B rotate relative to each other, the first tooth and the second tooth will change from the biting state to the tooth tip to tooth tip state. When the tooth tip to tooth tip, the axial length formed by the first connector and the second connector becomes longer, while the total length of the flipping mechanism remains unchanged. Therefore, the first connector squeezes the elastic component and compresses it. The first connector and the second connector rotate relative to each other by overcoming the restoring deformation force of the elastic component. Similarly, component A and component B remain relatively stationary by the restoring deformation force of the elastic component.

[0023] (2) The elastic component of this utility model is a helical spring. The first connecting component is provided with a guide portion that extends into the helical spring. When the helical spring is compressed, it can play a guiding and supporting role and prevent the helical spring from bending.

[0024] (3) In the flip screen of this utility model, a limiting part is provided on the outer periphery of the first connector, and the screen assembly 100 is provided with a sleeve that fits with the limiting part, so that when the sleeve is fitted on the limiting part, the screen assembly and the first connector cannot rotate relative to each other in the circumferential direction. The end of the second connector away from the elastic member is provided with a snap-fit ​​groove, and the base assembly is provided with a protrusion that matches the snap-fit ​​groove. Through the snap-fit ​​groove and the protrusion, the second connector and the base assembly cannot rotate in the circumferential direction. At the same time, the base assembly limits the ends of the two second connectors. The structure is simple and the assembly is convenient. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Example 1

[0039] See Figures 1 to 3 A flipping mechanism is provided, which allows component A to rotate relative to component B. It includes a spring element 10, a first connecting member 20, and a second connecting member 30. Two first connecting members 20 are fixedly connected to both ends of the spring element 10, and a first tooth 21 is provided at the end of the first connecting member 20 away from the spring element. Two second connecting members 30 are respectively located on both sides of the first connecting member 20 away from the spring element 10, and each second connecting member 30 has a second tooth 31. The teeth of the first tooth 21 and the second tooth 31 interlock and engage.

[0040] When assembling the flipping structure, component A is connected to two first connecting members 20, and component B is connected to two second connecting members 30, with axial restraint applied to the ends of the second connecting members 30 away from the first connecting members 20, thus restraining both ends of the flipping mechanism. It is understood that after assembly, the elastic member 10 is in a compressed state, ensuring that the first tooth 21 and the second tooth 31 are engaged. It should be understood that the actions of the two first connecting members and the two second connecting members in this application are synchronized; for ease of description, the numbers have been simplified.

[0041] When component A rotates relative to component B, that is, when the first connecting member 20 rotates relative to the second connecting member 30, the tooth tip of the first tooth 21 slides from the root of the second tooth 31 to the tooth tip and then to the next tooth root. This constitutes one gear rotation for the first connecting member 20 relative to the second connecting member 30. One tooth rotation completes one gear. During the process of the first tooth 21 sliding from the root of the second tooth 31 to the tooth tip, the axial direction of the flipping mechanism is limited, so the first connecting member 20 can only compress the elastic member 10. After flipping over the tooth tip of the second tooth 31, the first tooth 21 and the second tooth 31 continue to mesh under the restoring deformation force of the elastic member. Similarly, when component B rotates relative to component A, when the second tooth 31 slides from the root of the first tooth 21 to the tooth tip, it compresses the elastic member 10 from both ends, thus smoothly rotating one gear. Due to the restoring deformation force of the elastic component, the first tooth 21 and the second tooth 22 are always in a meshing state without the action of external force, that is, component A and component B are relatively stationary.

[0042] In this embodiment, the center lines of the first tooth 21 and the second tooth 31 coincide with the axis of the elastic member 10. Therefore, when the first connector and the second connector rotate relative to each other, the compressive force on the elastic member 10 can be uniform.

[0043] The elastic element 10 is a helical spring. A guide portion 22 is provided at the end of the first connecting member 20 facing the helical spring. The guide portion 22 extends into the interior of the helical spring and provides guidance and support during compression, preventing the helical spring from bending. Of course, the length of the guide portion 22 is less than the initial length of the helical spring, thus allowing the helical spring to have compression space.

[0044] Example 2

[0045] See Figure 4 and Figure 5 A flip screen, the flip mechanism described in Embodiment 1, further includes a screen assembly 100 and a base assembly 200, the screen assembly 100 and the base assembly 200 being connected through the flip mechanism.

[0046] Specifically, the screen assembly 100 is connected to two first connectors 20, and the screen assembly 100 and the first connectors 20 cannot rotate relative to each other, at least in the screen assembly's flipping direction. That is, the screen assembly 100 and the first connectors 20 are positioned at the upper limit in the circumferential direction of the first connectors 20, thereby allowing them to rotate synchronously in the circumferential direction. To achieve the upper limit in the circumferential direction of the screen assembly 100 and the first connectors 20, synchronous rotation can be achieved by fixing the screen assembly 100 and the first connectors 20 together; alternatively, a limiting part 23 can be provided on the outer periphery of the first connectors 20, and the screen assembly 100 can be provided with a sleeve 101 that fits against the limiting part 23, so that when the sleeve 101 is fitted onto the limiting part 23, the screen assembly 100 and the first connectors 20 cannot rotate relative to each other in the circumferential direction, i.e., they rotate synchronously.

[0047] The base assembly 200 is connected to two second connectors 30. The base assembly 200 limits the second connectors 30 in the axial direction. The base assembly 200 and the second connectors 30 cannot rotate relative to each other in the circumferential direction. That is, the base assembly 200 and the second connectors 30 rotate synchronously.

[0048] The second connector has a snap-fit ​​groove 32 at the end away from the elastic member. The base assembly 200 has a rib (not shown) that matches the snap-fit ​​groove 32. By snapping the snap-fit ​​groove 32 with the rib, the second connector 30 and the base assembly cannot rotate in the circumferential direction. At the same time, the base assembly limits the ends of the two second connectors 30, thereby limiting the axial movement of the flipping mechanism.

[0049] During assembly: ① Install the second connector on the base assembly, ensuring its locking groove engages with the protruding rib; ② Pass the first connector 20 and the elastic member 10, which are fixedly connected, through the sleeve 101 of the screen assembly 100, so that the sleeve 101 and the limiting part 23 are circumferentially limited; ③ Press the first connectors at both ends of the elastic member towards the middle, so that the length of the first connector and the elastic member is less than the distance between the two second connectors, and then release the first connector after aligning the first tooth with the second tooth. The base assembly also has a groove 201 for accommodating the sleeve 101. The sleeve 101 is placed in the groove 201, which also allows the base assembly 200 to support the screen assembly 100 and prevents the first connector 20 and the second connector 30 from sliding relative to each other in the horizontal direction.

[0050] In one embodiment, the screen assembly 100 is connected to the second connector 30, and the base assembly 200 is connected to the first connector 20. The principle is the same, and will not be described again here.

[0051] See Figure 6The base assembly includes an adjacent first plane 210 and a second plane 220. The angle α between the first plane 210 and the second plane 220 is greater than 180 degrees. The flipping mechanism is located at the intersection of the first plane 210 and the second plane 220. The rotation angle range of the screen assembly 100 is α-180 degrees. The screen assembly 100 rotates between being parallel to the first plane 210 and being parallel to the second plane 220.

It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
