Description

Technical Field

[0001] This invention relates to the field of noise reduction technology for automotive interior components, specifically a spring anti-sway mounting structure for a tabletop socket sealing assembly. Background Technology

[0002] The car center console is a car accessory installed between two seats, including the center armrest, and belongs to the car's interior system. Its ergonomic design aims to allow the driver to rest their arms during long drives, preventing soreness, numbness, and stiffness.

[0003] However, as people's demands for car functions increase, in order to fully utilize the car's center console without excessively occupying interior space, developers have added various structures to give the armrest box different functions, such as increasing the storage space for items by setting up foldable tables. Figures 9 to 10 As shown, to connect the foldable tabletop, tabletop insertion holes are made on both sides of the armrest box. To prevent these holes from being exposed and affecting aesthetics after the foldable tabletop is disassembled, a tabletop insertion hole sealing assembly is designed. Its main structure includes a housing, a plug, and an elastic element (spring). The spring's function is to move the plug outwards and block the insertion hole after the tabletop is removed. To make tabletop insertion easier, the spring's elasticity cannot be too high. Also, because the plug is lightweight, the spring doesn't need too much elasticity to reset it. For these two reasons, the selected spring's rigidity cannot be too high. However, in subsequent production, it was found that due to the low rigidity of the spring, it would wobble during vehicle operation due to inertia. Because the spring has a certain length, its two ends have small displacements due to their fit with the assembly position, while the middle part of the spring is suspended and has a larger displacement range. This suspended middle part of the spring is prone to colliding with the housing, generating noise. Additionally, the spring also collides with other contacting parts, generating noise. Therefore, its structure needs further improvement. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned deficiencies and to disclose to the public a spring anti-sway installation structure for a tabletop socket sealing component that is simple in structure, reasonable in design, easy to manufacture, and can effectively reduce noise.

[0005] The technical solution of this invention is implemented as follows: A spring-loaded anti-sway mounting structure for a tabletop socket sealing assembly includes a housing, with tabletop sockets adapted to a detachable tabletop at both ends of the housing. The housing contains a spring and a plug that can seal the corresponding tabletop socket under the action of the spring. The spring has at least one tight section in its suspended portion.

[0006] Further optimization measures for this technical solution are as follows: As an improvement, the spring has two to three closely spaced sections at intervals in its suspended portion. The presence of multiple closely spaced sections further enhances anti-sway performance, thereby reducing noise generation.

[0007] As an improvement, in the spring, the spacing between adjacent spring coils in the tightly closed section is one-third to one-half the spacing between adjacent spring coils in the non-tightly closed section of the spring.

[0008] As an improvement, a mounting base is provided inside the housing. Both ends of the mounting base protrude towards the plug and are provided with mounting portions. One end of the spring is fitted onto the mounting portion, and the other end is placed inside the plug. The inner side of the plug extends inward to form an extension portion. By providing the extension portion, the limiting length of the spring is increased, thus reducing the length of the suspended portion of the spring, which also aims to reduce the amplitude of swaying.

[0009] As an improvement, the mounting base is covered with a first vibration-absorbing and noise-reducing layer around the assembly part. This first vibration-absorbing and noise-reducing layer physically isolates the spring from the assembly part, preventing direct collisions between them.

[0010] As an improvement, the spring is covered with a second vibration-absorbing and noise-reducing layer. Similarly, the second vibration-absorbing and noise-reducing layer is to prevent direct collision between the spring and the mounting position.

[0011] As an improvement, the outer periphery of the plug is wrapped with a third vibration-absorbing and noise-reducing layer. The third vibration-absorbing and noise-reducing layer can effectively reduce the noise generated by the collision between the plug and the housing.

[0012] As an improvement, the inner wall of the plug is provided with inwardly protruding ribs. The ribs reduce the range of motion of the spring end, thereby reducing noise.

[0013] As an improvement, the mounting base has locking parts on both sides, and the housing has locking grooves that fit the locking parts. Each end face of the locking part has a protrusion. The mounting base and housing are locked together, resulting in a simple structure and convenient connection. The protrusions ensure a tight fit between the locking parts and the locking grooves, improving the connection's strength.

[0014] As an improvement, the bottom of the mounting base is provided with a plug-in portion, and the housing is provided with a slot that matches the plug-in portion; the top of the mounting base is provided with a protrusion portion. The bottom plug-in portion of the mounting base mates with the slot, which can play a positioning role during assembly and facilitate assembly; the protrusion portion makes it easier for assemblers to hold the mounting base for assembly, which can improve assembly efficiency.

[0015] The advantages of this invention compared to the prior art are: The present invention discloses a spring anti-sway installation structure for a tabletop socket sealing assembly. The structure is simple and reasonable. By setting a tight section in the suspended part of the spring, the rigidity of the suspended part is increased while ensuring that the overall rigidity of the spring does not change too much. This reduces the swaying of the suspended part of the spring and avoids noise caused by the collision between the suspended part of the spring and the housing. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings: The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0019] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0020] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0021] Example 1, as Figures 1 to 7 As shown, a spring anti-sway installation structure for a tabletop socket sealing assembly includes a housing 1. The two ends of the housing 1 are respectively provided with tabletop sockets adapted to a detachable tabletop. The housing 1 is provided with a spring 2 and a plug 3 that can seal the corresponding tabletop socket under the action of the spring 2. The spring 2 has a tight section 21 in its suspended part.

[0022] In the spring 2, the spacing between adjacent spring coils in the tightly packed section 21 is one-third to one-half the spacing between adjacent spring coils in the non-tightly packed section of the spring 2 (excluding the medium-tightly packed section 21, the rest of the spring 2 is non-tightly packed). In this embodiment, the spacing between adjacent spring coils in the tightly packed section 21 is one-half the spacing between adjacent spring coils in the non-tightly packed section.

[0023] Because the spacing between adjacent spring coils is small, the rigidity of the tightly closed section 21 of spring 2 is greater than that of the non-tight section. This allows the rigidity of the suspended part to be increased while maintaining the overall rigidity of spring 2 without significant changes. This reduces the swaying of the suspended part of the spring and prevents it from colliding with the housing and generating noise.

[0024] The housing 1 is provided with a mounting base 4. Both ends of the mounting base 4 are respectively provided with assembly parts 41 protruding towards the plug. One end of the spring 2 is fitted onto the assembly part 41, and the other end is placed inside the plug 3. The inner side of the plug 3 extends inward to form an extension part 31.

[0025] One end of the spring 2 is placed inside the plug 3 and abuts against the inner surface of the plug 3. The other end of the spring 2 is fitted over the mounting portion 41 of the mounting base 4 (i.e., the mounting portion 41 is placed inside the spring 2). Thus, the portion of the spring 2 not in contact with the mounting portion is suspended. The mounting portions are the plug 3 (including the extension portion 31) and the mounting portion 41 of the mounting base 4. The plug 3 itself and the extension portion 31 on the plug 3 restrict the shaking of the portion where the spring 2 and the plug 3 mate; while the mounting portion 41 of the mounting base 4 restricts the shaking of the portion where the spring 2 and the mounting portion 41 mate. By extending the length of the plug 3 through the extension portion 31, the length of the suspended portion in the middle of the spring 2 is reduced while maintaining the main structure of the plug 3, thereby reducing the shaking of the spring 2 and lowering noise.

[0026] The mounting base 4 is covered with a first vibration-absorbing and noise-reducing layer 4a on the outer periphery of the assembly part 41.

[0027] The spring 2 is covered with a second vibration-absorbing and noise-reducing layer 2a.

[0028] The outer periphery of the plug 3 is wrapped with a third vibration-absorbing and noise-reducing layer 3a.

[0029] By setting up vibration-absorbing and noise-reducing layers, physical isolation is achieved between components, preventing direct collisions and effectively reducing noise generation. The vibration-absorbing and noise-reducing layers should ideally be made of a soft and elastic material. In this embodiment, the first vibration-absorbing and noise-reducing layer 4a and the second vibration-absorbing and noise-reducing layer 2a are made of fleece fabric, which is soft and inexpensive.

[0030] The inner wall of the plug 3 is provided with an inwardly protruding rib 32. The rib 32 has two main functions: first, by setting the rib 32, the strength of the plug 3 can be increased; second, by setting the rib 32, the cross-sectional area of ​​the cavity of the plug 3 is reduced, which can further reduce the shaking of the spring 2 in the plug 3, thereby reducing the generation of noise.

[0031] The mounting base 4 is provided with a locking part 42 on both sides, and the housing 1 is provided with a locking groove 1a that is adapted to the locking part 42. The locking part 42 is provided with a protrusion 42a on both ends.

[0032] The mounting base 4 has a plug-in part 43 at its bottom, and the housing 1 has a slot 1b that is adapted to the plug-in part 43; the mounting base 4 has a protrusion 44 at its top.

[0033] When assembling the mounting base 4 with the housing 1, align the insertion part 43 at the bottom of the mounting base 4 with the insertion part 43 inside the housing 1 and insert it vertically, so that the locking parts 42 on both sides are inserted into the corresponding slots 1a. Since the locking parts 42 are provided with protrusions 42a, the locking parts 42 and the slots 1a are tightly fitted, thereby firmly fixing the mounting base 4 inside the housing 1. Since the two sides of the mounting base 4 cooperate with the housing 1, and the mounting parts 41 at both ends are equipped with springs 2, it is inconvenient to hold the mounting base 4 during assembly. Therefore, a protrusion 44 is designed on the top to facilitate holding and improve assembly efficiency.

[0034] The housing 1 is formed by the mating of an upper housing 11 and a lower housing 12. In this embodiment, the slot 1a and the slot 1b are both provided on the lower housing 12, and the spring 2 is a square spring.

[0035] Example 2, as Figure 8 As shown, the tabletop socket sealing assembly in this embodiment has the same structure as that in Embodiment 1. The difference is that the spring 2 in this embodiment has two closely spaced sections 21. Since the space for installing the spring 2 in the tabletop socket sealing assembly is limited, the length of the selected spring 2 will not be very long. Therefore, it is advisable to set 1 to 3 closely spaced sections 21 in the suspended part of the spring 2. Setting too many sections will affect the overall elasticity of the spring 2.

[0036] In the tabletop socket sealing assembly of the present invention, during assembly, one end of the spring 2 is placed inside the sealing member 3, and the other end is fitted over the mounting portion 41 of the mounting base 4; after assembling the sealing member 3, spring 2, and mounting base 4 into the lower housing 12, the upper housing 11 is placed on top of the lower housing 12 and then secured with screws. This completes the assembly of the tabletop socket sealing assembly. The entire tabletop socket sealing assembly is then installed on the armrest box 5, as shown below. Figure 9 As shown, after installation, without connecting the detachable tabletop 6, the sealing element 3 blocks the tabletop insertion hole; as Figure 10 As shown, when connecting the detachable tabletop 6, simply insert the detachable tabletop 6 into the tabletop insertion hole. At this time, the sealing member 3 compresses the spring 2 and retracts into the housing 1. The first guide portion 32 and the second guide portion 33 on the sealing member 3 cooperate with the corresponding guide grooves in the housing 1. This invention improves the stability and reliability of the guide by increasing the length of the first guide portion 32. The structure is simple and easy to implement.

[0037] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
