[0029] Please see Figure 1-12 A small table with a flip-damping structure includes a support plate 10, rivets 20, a shaft 30, multiple damping springs 40, a makeup mirror 50, and a small table 60. One end of the shaft 30 passes through the support plate 10 and the multiple damping springs 40 in sequence and extends to the outside of the damping springs 40. The rivets 20 pass through the support plate 10 and the multiple damping springs 40 in sequence and extend to the outside of the damping springs 40. The shaft 30 and the rivets 20 are arranged parallel to each other. The number of damping springs 40 is greater than three.

[0030] Example 2: The difference between this example and Example 1 is that the outer surface of the support plate 10 is provided with a first support plate mounting hole 10-1 and a second support plate mounting hole 10-2. The outer surface of the support plate 10 is provided with a vertical protrusion. The outer surface of the vertical protrusion is provided with a shaft mounting hole 10-3 and a rivet mounting hole 10-4. One end of the shaft 30 passes through the shaft mounting hole 10-3, and one end of the rivet 20 passes through the rivet mounting hole 10-4.

[0031] The support plate 10 provides support for the entire system and protects the damping spring 40. The rivet mounting holes 10-4 on the positioning part of the support plate 10 cooperate with the rivet through holes 40-8 on the damping spring 40 to fix and position the damping spring 40. The shaft mounting holes 10-3 and the shaft 30-1 on the support plate 10 provide guidance for the installation of the damping spring 40. The support plate 10 is tightly integrated with the damping spring 40 by rivets 20 and shaft 30 to prevent rotation and shaking, and to fix the damping spring 40 in the preset position. The first support plate mounting holes 10-1 and the second support plate mounting holes 10-2 on the support plate 10 are fixed to external components to prevent the support plate 10 from shaking and to ensure the reliability and stability of the entire system. Example 3: The difference between this example and Example 1 is that the rivet 20 includes a rivet rod 20-2, one end of which is equipped with a rivet head 20-3, and the other end of which is provided with a rivet ring 20-1.

[0032] Rivet 20 provides positioning for the entire system, ensuring that the damping spring 40 is installed in the correct position on the support plate 10. Rivet 20 is installed in the rivet through hole 40-8 on the protruding part at the lower end of the spring 40 and the rivet mounting hole 10-4 on the support plate 10, positioning the damping spring 40 on the support plate 10 to achieve a matching positioning function. After the damping spring 40 is assembled, the rivet rod 20-1 is riveted to prevent the damping spring 40 from falling off when twisted.

[0033] Example 4: The difference between this example and Example 1 is that the shaft 30 includes a shaft rod 30-1, one end of the shaft rod 30-1 is equipped with a shaft rod cap 30-3, and the outer surface of the shaft rod 30-1 is provided with a flat part 30-2.

[0034] Shaft 30 generates friction with the damping spring 40, providing reliable torque output to the system, and connects the support plate 10 to external components. Shaft rod 30-1 mates with shaft mounting hole 10-3. One end of shaft 30 is designed as a flat section 30-2 to prevent synchronous rotation of shaft 30 when the damping spring 40 twists. It also provides guidance during installation, ensuring stability. The structure is simple and compact, easy to assemble, and can meet the assembly requirements of various products, significantly saving installation time.

[0035] Example 5: The difference between this example and Example 1 is that the damping spring 40 includes a first spring portion 40-2, a second spring portion 40-5, a third spring portion 40-10, and a square portion 40-9. The outer surface of the damping spring 40 is provided with an opening 40-1 and a spring protrusion 40-4. The inner wall of the damping spring 40 is provided with a first oil groove 40-3 and a second oil groove 40-6. The first oil groove 40-3 is located between the first spring portion 40-2 and the second spring portion 40-5, and the second oil groove 40-6 is located between the second spring portion 40-5 and the third spring portion 40-10. The center of the damping spring 40 is provided with a shaft through hole 40-7, and the outer surface of the square portion 40-9 is provided with a rivet through hole 408.

[0036] The damping spring 40 is composed of one or more springs. The square part 40-9 serves as the fixed end. It is connected to the rivet 20 by using the rivet through hole 40-8 to form a mutual engagement. The two are tightly connected, so that the damping spring 40 and the support plate 10 remain relatively stationary, thereby achieving the function of matching and positioning.

[0037] The damping spring 40 has a first oil groove 40-3 and a second oil groove 40-6. When the shaft 30 passes through the damping spring 40, the damping spring 40 will undergo elastic deformation, providing stable and lasting pressure for the damping system. When the shaft 30 and the damping spring 40 generate relative motion, this pressure will be converted into frictional force.

[0038] The outer surface of the makeup mirror 50 is provided with a first makeup mirror hole 50-1 and a second makeup mirror hole 50-2. The first makeup mirror hole 50-1 and the second makeup mirror hole 50-2 are symmetrically distributed about the axis of the makeup mirror 50. The first makeup mirror hole 50-1 and the second makeup mirror hole 50-2 are both matched with the flat part 30-2.

[0039] The outer surface of the small table 60 has a makeup mirror storage compartment. The left side wall inside the makeup mirror storage compartment has a first shaft receiving hole 60-1, and the right side wall inside the makeup mirror storage compartment has a second shaft receiving hole 60-2.

[0040] Shaft 30-2 is installed in the first makeup mirror hole 50-1 and the second makeup mirror hole 50-2. Shaft 30 and damping spring 40 are placed together in the first shaft receiving hole 60-1 and the second shaft receiving hole 60-2.

[0041] Two sets of small table positioning holes are provided on the outer surface of the small table 60. Each set of small table positioning holes has two holes, namely the first small table positioning hole 60-3 and the second small table positioning hole 60-4. The first small table positioning hole 60-3 corresponds to the first support plate mounting hole 10-1, and the second small table positioning hole 60-4 corresponds to the second support plate mounting hole 10-2.

[0042] The first support plate mounting hole 10-1 and the second support plate mounting hole 10-2 are fixed to the first small table positioning hole 60-3 and the second small table positioning hole 60-4 to prevent the support plate 60 from shaking and to ensure the reliability and stability of the entire system.

[0043] Rivet 20 passes through rivet through hole 40-8. When damping spring 40 starts to rotate, shaft 30 does not rotate with it. The relative movement between the two causes friction between the shaft through hole 40-7 of damping spring 900 and the friction surface shaft 30-1 of shaft 30, thereby generating torque.

[0044] Furthermore, the shaft through-hole 40-7 is annularly spaced with a first oil groove 40-3 and a second oil groove 34-6. When the system is in use, the first oil groove 40-3 and the second oil groove 40-6 are filled with lubricating oil, which helps to keep the frictional damping of the damping spring as stable as possible during use. During long-term use, many mechanical parts may experience changes in damping force due to wear and other reasons. This oil groove design effectively avoids this situation, greatly improving the reliability and stability of the entire system and extending the service life of the system.

[0045] The damping spring 40 has different structures on both sides. The first part consists of a semicircle on one side extending from the spring protrusion 40-4 to the square portion 40-9. This part supports the third spring portion 40-5 and the third spring portion 40-10. The second part consists of a semicircle on one side extending from the spring protrusion 40-4 to the square portion 40-9. This part is the variable structure opening 40-1. The structure also incorporates a second oil groove 40-6 and a first oil groove 40-3. The main function of this part is to allow the variable structure first spring portion 40-2 to elastically deform under lateral external forces, providing a stable pressure to the shaft 30. When the damping system starts operating, the damping spring undergoes elastic deformation due to external forces. The opening 40-1 allows the spring to expand flexibly while maintaining a continuous and stable pressure on the shaft. A stable frictional force is generated between the shaft 30 and the damping spring 40 during relative movement. This friction provides a stable torque for the entire system, ensuring stable and reliable operation under various complex conditions, such as different speeds and loads.

[0046] In summary, this small table with a flip-damping structure provides reliable unlocking and locking functions for various operational states, such as pressing down for storage. The unlocking mechanism of this car table precisely locks and unlocks during the table's rising and lowering / storing operations. Through the coordinated operation of various components, reliability and stability are ensured, preventing accidental unlocking while the vehicle is in motion and guaranteeing safety. It is easy to operate, ergonomically designed, and user-friendly. The durable structure is easy to maintain, enhancing the table's performance and meeting users' needs for convenience and stability.
