Description

Technical Field

[0001] The utility model relates to a soundproof structure, and more particularly to a soundproof spring structure and a lifting cup holder. Background Art

[0002] The lifting of the lifting cup holder is mainly realized by a tower spring structure. However, certain noises will be generated during the compression and rebound processes of the tower spring. Generally, flocking the tower spring is used to eliminate the noise. However, the flocking process is complicated and costly. At the same time, glue is introduced in the middle, which is not environmentally friendly. In addition, a bagged spring with both ends closed is used to eliminate the noise. When the non-woven fabrics at both ends of the bagged spring are not edge-sealed, the edge at the bottom of the bag may interfere with the unlocking mechanism at the bottom of the lifting cup holder, causing problems such as jamming, as Figure 11 shown. Summary of the Utility Model

[0003] In order to solve the problems in the prior art such as the high cost of the flocked tower spring and the unlocking jamming caused by the non-edge-sealed non-woven fabric, the utility model provides a soundproof spring structure and a lifting cup holder.

[0004] According to the soundproof spring structure of the utility model, it is a bagged spring and includes a spring and a bag. Among them, the bag is sleeved on the outside of the spring, and the opposite ends of the bag are reversely wrapped and edge-sealed.

[0005] Preferably, the bag includes a body, a first edge and a second edge. Among them, the first edge and the second edge are edges axially extending outward from the top end and the bottom end of the body respectively, and they are respectively folded inward, reversely wrapped and connected to the inside of the body.

[0006] Preferably, the bag further includes welding points, and the first edge and the second edge are respectively fixed to the inside of the body by welding at the welding points. It should be understood that the first edge and the second edge can also be respectively fixed to the inside of the body by sewing or bonding.

[0007] Preferably, the spring is a tower spring.

[0008] Preferably, the bag is a non-woven bag, a nylon bag, a fiber bag, a cotton bag, a linen bag or a DuPont bag.

[0009] According to the lifting cup holder of the utility model, it includes a barrel body, a base, a pad body and the above-mentioned soundproof spring structure. Among them, the base is fixedly installed at the lower part of the barrel body, and the pad body is liftably installed inside the barrel body through the soundproof spring structure.

[0010] Preferably, the cushion body is provided with a locking hook. The lifting cup holder further includes a locking buckle and a return spring. The locking buckle is radially movably mounted on the base through the return spring. When the spring in the silent spring structure is in a non-compressed state, the cushion body is in a high position and the lifting cup holder is in an unlocked state. When the cushion body is pressed down to a low position, the locking hook cooperates with the locking buckle to define the locked state of the lifting cup holder.

[0011] Preferably, the lifting cup holder further includes a locking rod, which is mounted on the barrel body and connected to the locking buckle to drive the locking buckle to unlock.

[0012] Preferably, the lifting cup holder further includes a lifting track and a damper. The cushion body includes a first skeleton having the locking hook. The lifting track is fixedly mounted inside the barrel body, and the first skeleton is mounted on the lifting track through the damper.

[0013] Preferably, the cushion body further includes a second skeleton and an appearance pad. The appearance pad is fixedly mounted on the first skeleton through the second skeleton, so as to provide a supporting surface through the second skeleton and the appearance pad.

[0014] According to the silent spring structure of the present invention, the opposite ends of the sleeve bag are reversely wrapped and sealed to limit the axial and radial movement of the sleeve bag relative to the spring. The sleeve bag isolates the spring coils to play a silent role, and is low in cost and environmentally friendly compared with the flocked tower spring. According to the lifting cup holder of the present invention, through the reverse wrapping and sealing edge, problems such as interference between the bottom of the sleeve bag of the silent spring structure and the locking buckle, resulting in jamming, are avoided.

[0026] The following combines the accompanying drawings to give a preferred embodiment of the present invention and describes it in detail.

[0027] As Figures 1 - 2 shown, a lifting cup holder A according to a preferred embodiment of the present invention is installed inside the interior I of the vehicle V.

[0028] As Figures 3 - 5 shown, the lifting cup holder A includes a barrel body 1, a base 2, a cushion body 3, and a silent spring structure 4. Among them, the barrel body 1 is fixedly installed inside the interior I of the vehicle V (see Figure 2 ), the base 2 is fixedly installed at the lower part of the barrel body 1, and the cushion body 3 is installed inside the barrel body 1 in a liftable manner through the silent spring structure 4. Specifically, the silent spring structure 4 is installed inside the barrel body 1, connected to the base 2 at the bottom, and connected to the cushion body 3 at the top.

[0029] As Figures 6 - 8As shown, the silent spring structure 4 is a pocket spring, which includes a spring 41 and a sleeve bag 42. Among them, the sleeve bag 42 is sleeved outside the spring 41. When the spring 41 is subjected to an external force, the pitch of the coils decreases. After the external force is released, the spring 41 rebounds. The sleeve bag 42 isolates the coils of the spring 41, which can play a role in silencing. In this embodiment, the spring 41 is a conical spring. The conical spring is made of 65Mn material, and the surface treatment can be electrophoresis, galvanizing, etc. The pitch of the coils can be the same or different. The diameter of the bottom coil is the largest, and the diameter of the coils gradually decreases upward. It should be understood that the conical spring here is only an example rather than a limitation when the lifting distance is relatively large. In this embodiment, the sleeve bag 42 is a non-woven fabric bag. It should be understood that the sleeve bag can also be a nylon cloth bag, a fiber cloth bag, a cotton cloth bag, a hemp cloth bag, a DuPont cloth bag, a Tyvek cloth bag, etc. Specifically, the sleeve bag 42 includes a body 421, a first edge 422 and a second edge 423. Among them, the first edge 422 and the second edge 423 are edges extending outward along the axial direction L from the top end and the bottom end of the body 421 respectively, and they are respectively folded inward and wrapped around the spring 41 and connected to the inner side of the body 421. In this embodiment, the lengths of the first and second edges 422 and 423 are 10-15 mm respectively. In this embodiment, the sleeve bag 42 further includes welding points 424, and the first and second edges 422 and 423 are respectively fixed to the inner side of the body 421 by the welding points 424. It should be understood that the first and second edges can also be fixed to the inner side of the body by sewing or bonding respectively. The formation process of the silent spring structure 4 in this embodiment is as Figure 9 shown. First, a non-woven fabric roll with a thickness of 0.1-1 mm is used to provide sheet materials through cutting. The sheet materials are formed into a sleeve bag 42 with open top and bottom ends through sewing or edge sealing. The sleeve bag 42 is sleeved on the spring 41 by machine or manually. The non-woven fabric at the top and bottom ends of the spring 41 extends out 10-15 mm to form the first edge 422 and the second edge 423. After the first edge 422 and the second edge 423 are wrapped around, ultrasonic welding is used for edge sealing to provide the silent spring structure 4. It should be understood that the welding and edge sealing after wrapping here are only examples rather than limitations. In fact, sewing or bonding can also meet the requirements, achieving the purpose of silencing while restricting the axial and radial movement of the sleeve bag 42 relative to the spring 41.

[0030] Back to Figure 3 , the lifting cup holder A further includes a lifting track 5 and a damper 6. The cushion body 3 includes a first skeleton 31. Among them, the lifting track 5 is fixedly installed outside the barrel body 1, and the first skeleton 31 is installed on the lifting track 5 through the damper 6. In this embodiment, the damper 6 is assembled on the lifting track 5 and installed on both sides of the barrel body 1. Specifically, as Figure 4 shown, the bottom of the first skeleton 31 has a locking hook 3a.

[0031] As Figure 3 and Figure 4As shown, the cushion body 3 further includes a second framework 32 and an appearance cushion 33. Among them, the appearance cushion 33 is fixedly installed on the first framework 31 through the second framework 32, so as to provide a supporting surface through the second framework 32 and the appearance cushion 33. In this embodiment, the appearance cushion 33 is a soft cushion. In the specific assembly process, the first framework 31, the second framework 32 and the appearance cushion 33 are first assembled to form the cushion body 3, and then installed on the barrel body 1 from the upper end.

[0032] As Figure 3 and Figure 4 shown, the lifting cup holder A further includes a lock catch 7, a return spring 8 and a lock rod 9. Among them, the lock catch 7 is radially movably installed on the base 2 through the return spring 8, and the lock rod 9 is installed on the barrel body 1 and connected to the lock catch 7 to move the lock catch 7 as required. In this embodiment, the lock rod 9 is installed on the side surface of the barrel body 1.

[0033] As Figure 10 shown, when the spring 41 in the mute spring structure 4 is in a non-compressed state, the cushion body 3 is in a high position, and at this time the lifting cup holder A is in the unlocked state shown in the left figure. When the cushion body 3 is pressed down to a low position, the lock hook 3a of the cushion body 3 cooperates with the lock catch 7, and at this time the lifting cup holder A is in the locked state shown in the right figure. When an external force acts on the lock rod 9 to make the lock catch 7 move radially outwards, the lock hook 3a will be disengaged from the lock catch 7 to achieve unlocking. In particular, the mute spring structure 4 avoids problems such as jamming caused by possible interference between the bottom of the sleeve bag and the lock catch 7 through reverse edge wrapping (by welding or sewing or bonding).

Various changes can be made to the above embodiments of the present invention. That is, all simple, equivalent changes and modifications made according to the claims and the content of the specification of the present invention application shall fall within the scope of the claims of the present invention patent.
