Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a limiting component and a vehicle. Background Technology

[0002] In vehicles using related technologies, rubber limiters and plastic limit blocks are typically installed on the vehicle body and movable components (such as tailgates), respectively. After the component is fitted to the vehicle body, the contact between the rubber limiters and plastic limit blocks increases the holding force of the component in the lateral and longitudinal directions, thereby preventing vibration and adjusting for gap differences. Since the two limit blocks are bolted to the vehicle body and the component, plastic caps are usually used to cover the mounting holes on the two limit blocks to avoid unsightly exposed bolts. Friction ribs are also provided on the rubber limit blocks to prevent the plastic caps on the rubber limiters from contacting the plastic limit blocks and / or another plastic cap, which could cause noise. However, this design results in poor aesthetics for the rubber limit blocks, and the friction ribs can still produce noise after wear, affecting the user experience. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a limiting component, which has the advantages of low friction noise and high aesthetic appearance.

[0005] An embodiment of this utility model also proposes a vehicle.

[0006] The limiting component of this utility model embodiment includes a first limiting block, a first plug, a second limiting block, and a second plug. The first limiting block is adapted to be connected to a first pair of components, and the first plug is connected to the first limiting block. Both the first limiting block and the first plug are elastic components. The second limiting block is adapted to be connected to a second pair of components, and the second plug is connected to the second limiting block. At least one of the second limiting block and the second plug is a rigid component. When the first pair of components and the second pair of components are engaged, the at least one of the second limiting block and the second plug compresses the at least one of the first limiting block and the first plug.

[0007] According to the limiting component of this utility model embodiment, by setting the first limiting block and the first end cap to be elastic elements, and setting at least one of the second limiting block and the second end cap to be a rigid element, when the first pair of parts and the second pair of parts are engaged, the rigid element of the second limiting block and the second end cap presses against at least one of the first limiting block and the first end cap, thereby preventing the second pair of parts from shaking relative to the first pair of parts and adjusting the gap difference. Furthermore, this design avoids the two elastic elements from contacting and rubbing against each other, thus preventing excessive noise, and also eliminates the need for friction ribs on the first limiting block, resulting in a more aesthetically pleasing limiting component.

[0008] In some embodiments, both the second limiting block and the second plug are rigid components.

[0009] In some embodiments, both the first limiting block and the first plug are rubber components;

[0012] In some embodiments, the first mounting hole includes a first hole segment and a second hole segment arranged in a direction close to the first mating member, the cross-sectional area of ​​the first hole segment being larger than the cross-sectional area of ​​the second hole segment, the cross-section being perpendicular to the axial direction of the first hole segment, and the second hole segment accommodating a portion of the first threaded member.

[0013] The first plug includes a first rod portion fitted within the first hole segment. The cross-sectional area of ​​the first rod portion gradually decreases along the axial direction of the first rod portion. The maximum cross-sectional area of ​​the first rod portion is greater than the cross-sectional area of ​​the first hole segment, and the minimum cross-sectional area of ​​the first rod portion is less than the cross-sectional area of ​​the first hole segment but greater than the cross-sectional area of ​​the second hole segment.

[0014] In some embodiments, the first plug further includes a second rod portion fitted within the second hole segment, the second rod portion being connected to the first rod portion, the cross-sectional area of ​​the second rod portion gradually decreasing in a direction away from the first rod portion, the maximum cross-sectional area of ​​the second rod portion being greater than the cross-sectional area of ​​the second hole segment, and the minimum cross-sectional area of ​​the second rod portion being less than the cross-sectional area of ​​the second hole segment.

[0015] In some embodiments, the second limiting block is connected to the second opposing member via a second threaded component. The second limiting block has a second mounting hole on the side opposite to the second opposing member for accommodating part of the second threaded component.

[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] In related technologies, regarding the solution of setting friction ribs on the rubber limit block to prevent the plastic cap on the rubber limit component from contacting the plastic limit block and / or another plastic cap to generate abnormal noise, the applicant found through practice that when the vehicle has a long mileage, the friction ribs are prone to wear under the pressure of the plastic limit block and / or plastic cap, and the plastic cap is exposed again, causing the plastic cap of the rubber limit block to come into direct contact with the plastic limit block and / or another plastic cap. As a result, when the tailgate is on a bumpy road, the two limit blocks collide with each other, causing abnormal noise again.

[0027] To address the aforementioned shortcomings, the following will be combined with... Figures 1-3 A limiting component according to an embodiment of the present utility model is described.

[0028] The limiting component of this utility model embodiment includes a first limiting block 1, a first plug 2, a second limiting block 3, and a second plug 4. The first limiting block 1 is adapted to be connected to a first pair of components, and the first plug 2 is connected to the first limiting block 1. Both the first limiting block 1 and the first plug 2 are elastic components. The second limiting block 3 is adapted to be connected to a second pair of components, and the second plug 4 is connected to the second limiting block 3. At least one of the second limiting block 3 and the second plug 4 is a rigid component. When the first pair of components and the second plug 4 are engaged, at least one of the first limiting block 1 and the first plug 2 is compressed.

[0029] According to the limiting component of this utility model embodiment, by setting the first limiting block 1 and the first end cap 2 to be elastic elements, and setting at least one of the second limiting block 3 and the second end cap 4 to be a rigid element, when the first pair of parts and the second pair of parts are engaged, the rigid element of the second limiting block 3 and the second end cap 4 presses against at least one of the first limiting block 1 and the first end cap 2, thereby preventing the second pair of parts from shaking relative to the first pair of parts and adjusting the gap difference. Furthermore, this design avoids the two elastic elements from contacting and rubbing against each other, thus preventing excessive noise, and also eliminates the need for friction ribs on the first limiting block 1, resulting in a more aesthetically pleasing limiting component.

[0030] It should be noted that the first limiting block 1 and the first cover 2 are elastic components made of rubber or silicone material. When they come into contact with rigid components, they can be compressed and deformed to achieve the function of energy absorption and noise reduction. The limiting components will be further introduced below using the first pair of components as the car body and the second pair of components as the tailgate as an example.

[0031] In some embodiments, the second limiting block 3 and the second plug 4 are both rigid components.

[0032] In other words, when the tailgate is closed, both the second limiting block 3 and the second cover 4 on the tailgate can contact the first limiting block 1 and the first cover 2 on the vehicle body, thereby limiting the tailgate in both the left-right and front-back directions. This design allows for flexible structural and positional design of the second limiting block 3 and the second cover 4. It also effectively ensures the connection strength between the second limiting block 3 and the second cover 4. When the second cover 4 is subjected to pressure from the first cover 2 and the first limiting block 1, the second cover 4 is less likely to detach and affect the protection of the bolts inside the second limiting block 3. The limiting assembly has a more aesthetically pleasing appearance and a longer service life.

[0033] In some embodiments, the first limiting block 1 and the first plug 2 are both rubber parts. And / or, the second limiting block 3 and the second plug 4 are both plastic parts.

[0034] This design further reduces the abnormal noise generated when each of the first limiting block 1 and the first plug 2 comes into contact with the second limiting block 3 and the second plug 4, and also further reduces the wear rate of the first limiting block 1 and the first plug 2, resulting in a longer service life for the limiting components.

[0035] Meanwhile, the design that the first limiting block 1 and the first plug 2 are made of the same material, and the second limiting block 3 and the second plug 4 are made of the same material, also avoids the formation of color difference, and the appearance of the limiting components is more aesthetically pleasing.

[0036] The first limiting block 1 and the first plug 2 are made of EPDM (Ethylene Propylene Diene Monomer) or TPV (Thermoplastic Vulcanizate). The second limiting block 3 and the second plug 4 are made of PA66 (Polyamide 66), PC+ABS, or POM (Paraformaldehyde).

[0037] It should be noted that the first limiting block 1 and the first plug 2 can also be made of silicone material, and the second limiting block 3 and the second plug 4 can also be made of hard materials such as metal.

[0038] In some embodiments, the first limiting block 1 is connected to the first pair of components via the first threaded component. The first limiting block 1 is provided with a first assembly hole 11 on the side opposite to the first pair of components for accommodating part of the first threaded component. The first plug 2 is interference-fitted into the assembly hole.

[0039] Since both the first limiting block 1 and the first plug 2 are rubber parts, the first plug 2 is interference-fitted with the first mounting hole 11 on the first limiting block 1, so that the first plug 2 can be installed on the first limiting block 1. The installation of the first plug 2 is convenient and reliable, and it has a good sealing effect on the first mounting hole 11. The first threaded part in the first mounting hole 11 has a good waterproof effect.

[0040] Specifically, the first threaded component is a bolt. After the first limiting block 1 is connected to the vehicle body by the bolt, the head of the bolt is located in the first assembly hole 11.

[0041] In some embodiments, the first mounting hole 11 includes a first hole segment 111 and a second hole segment 112 arranged along a direction close to the first mounting member. The cross-sectional area of ​​the first hole segment 111 is larger than that of the second hole segment 112, and the cross-section is perpendicular to the axial direction of the first hole segment 111. The second hole segment 112 accommodates a portion of the first threaded member. The first plug 2 includes a first rod portion 21 that fits within the first hole segment 111. The cross-sectional area of ​​the first rod portion 21 gradually decreases along the axial direction of the first rod portion 21. The maximum cross-sectional area of ​​the first rod portion 21 is larger than that of the first hole segment 111, and the minimum cross-sectional area of ​​the first rod portion 21 is smaller than that of the first hole segment 111 but larger than that of the second hole segment 112.

[0042] like Figure 3 As shown, the outer periphery of the first rod 21 is generally a frustum-shaped structure, that is, a structure that is thinner at the bottom and thicker at the top. This effectively reduces the difficulty of fitting the first rod 21 into the first hole 111, while also ensuring that the upper end of the first rod 21 can be interference-fitted into the first hole 111, thus ensuring the sealing of the connection between the first rod 21 and the first limiting block 1.

[0043] Specifically, the first hole segment 111 is generally a rectangular hole, the maximum length of the outer contour of the cross section of the first rod portion 21 is greater than the length of the outer contour of the cross section of the first hole segment 111 and the difference between the two is greater than or equal to 0.5 mm, and the maximum width of the outer contour of the cross section of the first rod portion 21 is greater than the width of the outer contour of the cross section of the first hole segment 111 and the difference between the two is greater than or equal to 0.5 mm.

[0044] In some embodiments, the first plug 2 further includes a second rod portion 22 that fits within the second hole section 112. The second rod portion 22 is connected to the first rod portion 21. The cross-sectional area of ​​the second rod portion 22 gradually decreases in the direction away from the first rod portion 21. The maximum cross-sectional area of ​​the second rod portion 22 is greater than the cross-sectional area of ​​the second hole section 112, and the minimum cross-sectional area of ​​the second rod portion 22 is less than the cross-sectional area of ​​the second hole section 112.

[0045] That is, the outer periphery of the second rod 22 is also roughly a frustum-shaped structure with a thinner bottom and a thicker top, making it easier to fit the second rod 22 into the second hole section 112, thus increasing the installation efficiency of the first plug 2 on the first limiting block 1. At the same time, the interference fit between the second rod 22 and the second hole section 112 creates a secondary seal between the first plug 2 and the first assembly hole 11, resulting in a higher waterproofing effect on the bolt head inside the second hole section 112.

[0046] Specifically, the outer contour of the cross-section of the second hole section 112 and the second rod section 22 is rectangular.

[0047] In some embodiments, the second limiting block 3 is connected to the second opposing member through the second threaded member. The side of the second limiting block 3 facing away from the second opposing member is provided with a second assembly hole 31 for accommodating part of the second threaded member. The second plug 4 is engaged with the second limiting block 3 and blocks the second assembly hole 31.

[0048] With both the second limiting block 3 and the second plug 4 being rigid components, the snap-fit ​​connection between the second plug 4 and the second limiting block 3 effectively improves the installation efficiency of the second plug 4. This design also allows the second plug 4 to seal the second assembly hole 31, effectively preventing external moisture from entering the second threaded component in the second assembly hole 31 and affecting the service life of the second threaded component.

[0049] Specifically, the second threaded component is a bolt. After the second limiting block 3 is connected to the tailgate by the bolt, the head of the bolt is located in the second assembly hole 31.

[0050] In some embodiments, such as Figure 2 As shown, the inner wall of the second assembly hole 31 is provided with a locking hole 32, and the second plug 4 is provided with a buckle 41. The buckle 41 extends into the second assembly hole 31 and is locked in the locking hole 32. Thus, the second plug 4 is easy and reliable to install on the second limiting block 3.

[0051] Specifically, there are at least two locking holes 32 arranged at intervals along the circumference of the second mounting hole 31. The buckles 41 correspond one-to-one with the locking holes 32. When installing the second plug 4, one buckle 41 can be inserted into one of the locking holes 32 to complete the positioning. Then, the remaining buckles 41 can be forcefully snapped into the corresponding buckles 41 to realize the installation of the second plug 4 on the second limiting block 3.

[0052] The vehicle according to the present utility model includes a first pair of components, a second pair of components, and a limiting component as described in any of the above embodiments, wherein the first limiting block 1 is connected to the first pair of components, and the second limiting block 3 is connected to the second pair of components.

[0055] As a result, the limiting components can be used in a wider range of vehicles, and the cost of limiting and preventing swaying of tailgates, engine hoods and luggage compartment covers can be effectively reduced.
