Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a bracket for reducing swing noise. It is a bracket installed on a bicycle, and its structure can reduce noise generation during the unfolding and folding process. Background Technology

[0002] To make it easier for bicycles to stand upright when not being ridden, many users choose to install a stand on the bicycle frame. In order to avoid the stand interfering with riding, the stand usually has the function of unfolding and folding. However, the stand generates a lot of noise during the unfolding and folding process, which is a rather annoying problem for many users.

[0003] To address the aforementioned issues, various products have been released on the market (such as Taiwan Patent No. M601205 and European Patent No. EP4375173) to improve the noise generated during the unfolding and folding of the bracket. However, some of these products have drawbacks. For example, European Patent No. EP3208182 describes a specific structure that creates gaps between parts of the bracket that would otherwise collide and generate noise during unfolding and folding. This reduces the likelihood of noise during these processes. However, this structure still has its flaws. To maintain structural stability, the aforementioned gaps cannot be too large, otherwise it will affect the stability of the bracket during unfolding and folding. Therefore, displacement or deformation between parts, or manufacturing tolerances, can cause the aforementioned gaps to disappear, thus rendering the noise reduction effect ineffective. This makes it a product that requires a very high degree of precision in the assembly of individual parts. Utility Model Content

[0004] This invention addresses the problem of conventional noise reduction pads being placed in the column groove of the column or in the joint protrusion of the connecting member. Whether unfolded or folded, the noise reduction pads provide a barrier between the first joint abutment section and the first groove abutment section, and between the second joint abutment section and the second groove abutment section. Furthermore, the noise reduction pads are elastic, thus effectively eliminating noise. Compared to the noise reduction principle of traditional products, which does not rely on the precision of assembly between parts, this invention provides better stability in reducing noise generated during the unfolding and folding of the support, demonstrating novelty and progress.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A support for reducing swaying noise, comprising:

[0007] A connecting member has a connecting joint at one end and a vehicle body connecting part at the other end. The connecting joint includes a first joint abutment section and a second joint abutment section, and a joint protrusion section is connected between the first joint abutment section and the second joint abutment section.

[0008] A column has a ground-supporting part at one end and a column groove at the other end. The column groove has a groove opening, and a pivot piece is provided on each of the two corresponding sides of the groove opening. The parts of the groove opening without pivot pieces are a first groove opening abutment section and a second groove opening abutment section, respectively. The joint protrusion section is pivotally connected between the two pivot pieces by a shaft.

[0009] An elastic sound-absorbing pad is disposed in a column groove. The sound-absorbing pad includes a first wing and a second wing. The first wing is attached to the first groove opening and the second wing is attached to the second groove opening and the second wing is attached to the second groove opening and the second wing.

[0010] When the column is in an unfolded state relative to the connecting member, the first joint abutment section abuts against the first wing; when the column is in a folded state relative to the connecting member, the second joint abutment section abuts against the second wing.

[0011] Furthermore, the shape of the sound-absorbing pad matches the shape of the column groove and the two pivot plates.

[0012] Furthermore, the shaft passes through the sound-absorbing pad.

[0013] A bracket for reducing swaying noise includes: a connector having a connecting joint at one end and a vehicle body connecting part at the other end; the connecting joint includes a first joint abutment section and a second joint abutment section, and a joint protrusion section is connected between the first joint abutment section and the second joint abutment section.

[0014] A column has a ground-supporting part at one end and a column groove at the other end. The column groove has a groove opening, and a pivot piece is provided on each of the two corresponding sides of the groove opening. The parts of the groove opening without pivot pieces are a first groove opening abutment section and a second groove opening abutment section, respectively. The joint protrusion section is pivotally connected between the two pivot pieces by a shaft.

[0015] An elastic sound-absorbing pad is disposed on the joint protrusion section. The sound-absorbing pad includes a first wing and a second wing. The first wing is attached to the first joint abutment section, and the second wing is attached to the second joint abutment section.

[0016] When the column is in an unfolded state relative to the connecting member, the first slot abutting section abuts against the first wing; when the column is in a folded state relative to the connecting member, the second slot abutting section abuts against the second wing.

[0017] Furthermore, the sound-absorbing pad is wrapped around the joint protrusion.

[0018] Furthermore, the shaft passes through the sound-absorbing pad.

[0019] The beneficial effects of this utility model are as follows: This utility model sets the sound-absorbing pad in the column groove of the column or in the joint protrusion of the connecting member. Whether it is unfolded or folded, there will be a sound-absorbing pad between the first joint abutment section and the first groove abutment section, and between the second joint abutment section and the second groove abutment section. Moreover, the sound-absorbing pad is elastic, so it does have the function of eliminating noise. Compared with the sound-absorbing principle of traditional products, which does not rely on the assembly precision between parts, this utility model has a better improvement in the stability of the noise generated when the bracket is unfolded and folded. It has novelty and progress. Attached Figure Description

[0032] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0033] like Figures 1 to 5 As shown, the present invention provides a bracket for reducing swaying noise, comprising: a connector 1, one end of which has a connecting joint 11, and the other end of which is a vehicle body connecting part 12 (for connecting a bicycle). The connecting joint 11 includes a first joint abutment section 111 and a second joint abutment section 112, and a joint protrusion section 113 is connected between the first joint abutment section 111 and the second joint abutment section 112; and a column 2, one end of which is a ground abutment part 21 (for abutting against the ground), and the other end of which is a column groove 22. The column groove 22 has a slot 221, and two pivot plates 222 are respectively located on two corresponding sides of the slot 221. No pivot plates are provided at the slot 221. The components of 222 are a first groove abutment section 223 and a second groove abutment section 224. The joint protrusion section 113 is pivotally connected between the two pivot pieces 222 by a shaft 3. An elastic sound-absorbing pad 4 is disposed in the column groove 22. The sound-absorbing pad 4 includes a first wing 41 and a second wing 42. The first wing 41 is attached to the first groove abutment section 223, and the second wing 42 is attached to the second groove abutment section 224. When the column 2 is in an unfolded state relative to the connecting member 1, the first joint abutment section 111 abuts against the first wing 41. When the column 2 is in a folded state relative to the connecting member 1, the second joint abutment section 112 abuts against the second wing 42.

[0034] In addition, the shape of the sound-absorbing pad 4 matches the shape of the column groove 22 and the two pivot plates 222; the sound-absorbing pad 4 with this shape can be more stably installed in the column groove 22.

[0035] like Figures 6 to 10As shown, this utility model also has another embodiment, which is a bracket for reducing swaying noise, comprising: a connector 1, one end of which has a connecting joint portion 11, and the other end of which is a vehicle body connecting portion 12. The connecting joint portion 11 includes a first joint abutment section 111 and a second joint abutment section 112, and a joint protrusion section 113 is connected between the first joint abutment section 111 and the second joint abutment section 112; a column 2, one end of which is a ground abutment portion 21, and the other end of which is a column groove 22. The column groove 22 has a slot 221, and two pivot plates 222 are respectively located on two corresponding sides of the slot 221. The slot 221 does not have a pivot plate 222. The joint protrusion 113 is pivotally connected to the two pivot plates 222 by a shaft 3, and has a first groove abutment section 223 and a second groove abutment section 224 respectively. The joint protrusion 113 is pivotally connected to the two pivot plates 222 by a shaft 3. The joint protrusion 113 has an elastic sound-absorbing pad 4, which is disposed on the joint protrusion 113. The sound-absorbing pad 4 includes a first wing 41 and a second wing 42. The first wing 41 is attached to the first joint abutment section 111, and the second wing 42 is attached to the second joint abutment section 112. When the column 2 is in an unfolded state relative to the connecting member 1, the first groove abutment section 223 abuts against the first wing 41. When the column 2 is in a folded state relative to the connecting member 1, the second groove abutment section 224 abuts against the second wing 42.

[0036] The difference between this embodiment and the previous embodiment is that the sound-absorbing pad 4 is set on the joint protrusion 113 and is set in a covering manner, making it less likely to fall off.

[0037] This invention addresses the problem of conventional methods where the sound-absorbing pad is placed in the column groove 22 of the column 2 or in the joint protrusion 113 of the connecting member 1, regardless of whether it is unfolded ( Figure 3 and Figure 8 ), collection ( Figure 5 and Figure 10 When the first joint abutment section 111 and the first groove abutment section 223 are in contact ( Figure 3 and Figure 8 ), between the second joint abutment section 112 and the second groove abutment section 224 ( Figure 5 and Figure 10 All of them have sound-absorbing pads 4 to block the noise, and the sound-absorbing pads 4 are elastic, so they do have the function of eliminating noise. Compared with the sound-absorbing principle of traditional products, the sound-absorbing pads 4 do not rely on the assembly precision between parts. This utility model has better stability of the noise generated when the bracket is unfolded and folded, and is novel and progressive.

[0038] Furthermore, regardless of the embodiment of this utility model, when the sound-absorbing pad 4 is set, the shaft 3 can pass through the sound-absorbing pad 4 to prevent the sound-absorbing pad 4 from easily falling off. Moreover, the part of the sound-absorbing pad 4 corresponding to the pivot piece 222 can avoid the abnormal noise generated by the direct friction between the joint protrusion 113 and each pivot piece 222.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
