Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, and more specifically, to a shock absorber with a dust-proof bushing and an automobile. Background Technique

[0002] At present, there are mainly two assembly methods for the shock absorber dust cover. One is to directly put it on the shock absorber, and the other is to fix the dust cover on the shock absorber through a fixing fixture or screws. Through actual use, it is found that both of these assembly methods have deficiencies. First, for the assembly method of directly putting it on the shock absorber, the dust cover is usually made of rubber or plastic materials and is designed in a set form according to the shape and size of the shock absorber, and then directly put on the shock absorber. Although this assembly method is simple to install, it is easy to loosen or fall off, affecting the dust-proof effect. Moreover, during driving, the dust cover may fall off due to vibration, resulting in the shock absorber being exposed to the external environment and being easily contaminated by dust, water vapor, etc. Second, for the assembly method of fixing fixtures or screws, generally, a special fixing fixture (such as a clamp) or screws are used to fix the dust cover on the shock absorber, which can ensure that the dust cover is firmly fixed on the shock absorber and improves the dust-proof effect to a certain extent. However, this assembly method requires additional parts, such as fixtures or screws, increasing the production cost; and the installation process is relatively complex and requires additional processes, resulting in low production efficiency. It can be seen that the existing assembly methods of shock absorber dust covers need to be improved. Content of the Utility Model

[0003] The purpose of the utility model is to provide a shock absorber with a dust-proof bushing and an automobile, so as to solve the technical problems that the assembly method of the dust-proof bushing on the existing shock absorber is easy to fall off during use or the assembly process is complex.

The two ends of the dust-proof bushing are respectively detachably connected to the bushing connecting pieces on the upper fixed seat and the lower fixed seat. The dust-proof bushing is sleeved around the piston rod of the shock absorber and is fixedly connected to the shock absorber through the upper fixed seat and the lower fixed seat. The top end of the piston rod is rotatably connected to the upper fixed seat. When the piston rod expands and contracts, the upper fixed seat moves together with the piston rod.

Detailed implementation mode

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] It should be noted that when a component is referred to as "fixed to" or "disposed on" another component, it can be directly or indirectly located on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component. The orientations or positions indicated by the terms "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientations or positions shown in the drawings, and are only for the convenience of description and cannot be construed as a limitation to the technical solution of the present application. The terms "first" and "second" are only used for the purpose of convenient description and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of technical features. The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0025] Referring to the figure, in the first embodiment of the present utility model, a shock absorber with a dust-proof bushing is provided, which includes a shock absorber oil cylinder, a piston rod, a fixing seat, a bushing connecting piece and a dust-proof bushing. The fixing seat includes an upper fixing seat and a lower fixing seat. A bushing connecting piece is connected to the middle position of each of the upper fixing seat and the lower fixing seat. The two ends of the dust-proof bushing are respectively detachably connected to the bushing connecting pieces on the upper fixing seat and the lower fixing seat. The dust-proof bushing is sleeved around the piston rod of the shock absorber and is fixedly connected to the shock absorber through the upper fixing seat and the lower fixing seat. The top end of the piston rod is rotatably connected to the upper fixing seat. When the piston rod expands and contracts, the upper fixing seat moves together with the piston rod.

[0026] The above shock absorber with a dust-proof bushing can be applied to an automobile. It is connected to both ends of the dust-proof bushing through a bushing connecting member provided on a fixed seat, and then the dust-proof bushing is connected and fixed to the shock absorber through the fixed seat, thereby completing the installation and fixation of the dust-proof bushing. Compared with the existing assembly method of directly fixing the dust-proof cover on the shock absorber through a special fixing fixture or screw, the dust-proof bushing connection structure provided in this embodiment can avoid the problem that the dust-proof bushing rubs against the clamp under a vibration scenario, resulting in wear at the connection between the dust-proof bushing and the clamp, and causing the dust-proof bushing to become loose or even fall off after a long time of use. It not only plays a role in protecting the dust-proof bushing, improves the fixing effect of the dust-proof bushing on the shock absorber, but also enhances the reliability and durability of the dust-proof bushing.

[0027] Among them, the specific implementation methods for realizing the detachable connection between the bushing connecting member and the dust-proof bushing are not unique. For example, the bushing connecting member and the dust-proof bushing can be connected by threads or snap connection, or both thread connection and snap connection can be used simultaneously.

[0028] In an alternative embodiment, referring to the figure, a fixing ring is connected to each end of the dust-proof bushing, and a first thread is provided on the inner wall of the fixing ring;

[0029] The bushing connecting member includes a connecting ring corresponding to the fixing ring. A second thread matching the first thread is provided on the outer wall of the connecting ring. The bushing connecting member is connected to the dust-proof bushing through the cooperation of the first thread and the second thread.

[0030] Specifically, the fixing ring is connected to the outer wall of the connecting ring through the cooperation of the first thread and the second thread. Through this threaded connection method, both ends of the dust-proof bushing can be respectively connected to the bushing connecting members of the upper fixed seat and the lower fixed seat. When assembling the dust-proof bushing, the connecting ring of the bushing connecting member on the upper fixed seat can be aligned with the fixing ring at one end of the dust-proof bushing first, and then the upper fixed seat is rotated to make the second thread move along the first thread, so that the fixing ring and the connecting ring are threadedly connected, thereby connecting one end of the dust-proof bushing to the upper fixed seat; then the connecting ring of the bushing connecting member on the lower fixed seat is aligned with the fixing ring at the other end of the dust-proof bushing, and then the lower fixed seat is rotated to make the second thread move along the first thread, so that the fixing ring and the connecting ring are threadedly connected, thereby connecting the other end of the dust-proof bushing to the lower fixed seat, thus completing the connection of both ends of the dust-proof bushing to the upper and lower fixed seats.

[0031] In an alternative embodiment, referring to the figure, a fixing ring is connected to each end of the dust-proof bushing, and a first connecting buckle is provided on the inner wall / outer wall of the fixing ring;

[0032] The bushing connector includes a connecting ring corresponding to the fixing ring. A second connecting buckle is provided on the outer wall / inner wall of the connecting ring, and the second connecting buckle can be engaged and matched with the first connecting buckle. The bushing connector is connected to the dust-proof bushing through the clamping cooperation between the first connecting buckle pattern and the second connecting buckle.

[0033] Specifically, the first connecting buckle and the second connecting buckle rely on mechanical interlocking or elastic deformation to achieve a tight connection, restricting the relative movement of the fixing ring and the connecting ring in the axial direction. Among them, the structures for the first connecting buckle and the second connecting buckle to achieve clamping are not unique. For example, in this embodiment, both the first connecting buckle and the second connecting buckle are annular protrusions, and at least one of the connecting ring and the fixing ring is elastic.

[0034] When connecting the dust-proof bushing and the bushing connector, align the fixing ring and the connecting ring. The diameter of the fixing ring is generally just large enough to cover the connecting ring. Then, move the fixing ring and the connecting ring towards each other in the axial direction so that the first connecting buckle and the second connecting buckle are in a state of mutual extrusion at the contact position. Since at least one of the connecting ring and the fixing ring is elastic, the elastic one will deform under extrusion to produce radial contraction or expansion, allowing the first connecting buckle and the second connecting buckle to cross each other to form a state of axial mutual locking, thereby tightly connecting one end of the bushing connector and the dust-proof bushing together. It can be understood that the annular protrusions on the fixing ring and the connecting ring can be more than one circle, and can be multiple circles. In the case of multiple circles, it is optimal that the distance between two adjacent annular protrusions can just accommodate one annular protrusion, so that axial looseness can be ensured when the first connecting buckle and the second connecting buckle are connected, playing a role in clamping connection.

[0035] In an alternative embodiment, referring to the figure, a fixing ring is connected to each end of the dust-proof bushing. A first thread is provided on the inner wall of the fixing ring, and a first connecting buckle is provided at the bottom of the first thread;

[0036] The bushing connector includes a connecting ring corresponding to the fixing ring, and the height of the connecting ring is greater than the height of the fixing ring. A second thread matching the first thread is provided on the outer wall of the connecting ring, and a second connecting buckle is provided at the top of the second thread. The second connecting buckle can be engaged and matched with the first connecting buckle. When the second thread rotates along the first thread to the end, the first connecting buckle on the fixing ring and the second connecting buckle on the connecting ring are locked through mutual clamping cooperation.

[0037] This embodiment realizes the connection and fixation between the bushing connector and the dust-proof bushing through two connection methods: threaded connection and clamping connection. Optionally, both the first connecting buckle and the second connecting buckle are annular protrusions, and at least one of the connecting ring and the fixing ring is elastic.

[0038] Specifically, in the bushing connector, the second thread on the outer sidewall of the connecting ring is rotationally connected to the first thread on the inner wall of the fixing ring to connect the bushing connector and the dust-proof bushing together. Since the height of the connecting ring is greater than the height of the fixing ring, when the fixing ring and the connecting ring are connected, when the second thread rotates along the first thread to the end, the first connection buckle on the inner wall of the fixing ring at the lower end of the second thread presses against the upper outer edge of the connecting ring and finally locks with the second connection buckle on the outer edge of the connecting ring, thereby completing the overall installation connection and fixation of the dust-proof bushing and the bushing connector. In this embodiment, by using the cooperation of the second thread on the connecting ring of the bushing connector and the first thread on the fixing ring of the dust-proof bushing, and at the end position of the threaded connection between the second thread and the first thread, and then through the snap-fit of the first connection buckle on the fixing ring and the second connection buckle on the connecting ring, a detachable and fastening connection between the bushing connector and one end of the dust-proof bushing is achieved. In the scenario where the shock absorber vibrates, this dual combination connection method can effectively prevent the dust-proof bushing from falling off.

[0039] Specifically, the dust-proof bushing is connected to the shock absorber through a fixing seat. Among them, the connection method between the fixing seat and the shock absorber is not unique.

[0040] For example, in an alternative embodiment, referring to the figure, the shock absorber includes a connection seat for connecting the dust-proof bushing. The connection seat includes an upper connection seat and a lower connection seat. The upper connection seat is fixedly connected to the upper fixing seat, and the lower connection seat is fixedly connected to the shock absorber oil cylinder of the shock absorber and is fixedly connected to the lower fixing seat.

[0041] Preferably, both the connection seat and the fixing seat are flange plates. The flange plates are provided with connection holes. The two connection seats and the fixing seat are fixedly connected together by using fasteners at the connection hole positions of the flange plates. Specifically, as shown in the figure, the upper connection seat is provided with a plurality of first connection holes (for example, the number is 4), and the upper fixing seat is provided with a plurality of second connection holes (for example, the number is also 4). The positions of the first connection holes and the second connection holes correspond to each other. Fasteners such as bolts, nuts or screws can pass through the first connection holes and the second connection holes to fixedly connect the upper fixing seat and the upper connection seat together, that is, one end of the dust-proof bushing is fixed on the upper connection seat. In addition, the lower connection seat is provided with a plurality of third connection holes, and the lower fixing seat is provided with a plurality of fourth connection holes. The positions of the third connection holes and the fourth connection holes correspond to each other. Fasteners such as bolts, nuts or screws can pass through the third connection holes and the fourth connection holes to fixedly connect the lower fixing seat and the lower connection seat together, that is, the other end of the dust-proof bushing is fixed on the lower connection seat. Thus, the operation of installing the dust-proof bushing on the upper and lower connection seats of the shock absorber through the bushing connector is completed.

[0042] According to the technical solution provided by the embodiment of the present utility model, the assembly process of the dust-proof bushing of the shock absorber is as follows: First, one end of the dust-proof bushing is detachably snap-fitted and fixed to the bushing connecting member of the upper fixed seat. Then, the other end of the dust-proof bushing is detachably snap-fitted and fixed to the bushing connecting member of the lower fixed seat. Then, the piston rod of the shock absorber is passed through the dust-proof bushing, so that the dust-proof bushing is sleeved around the piston rod, and the top end of the piston rod is rotatably connected to the upper fixed seat. Finally, the upper fixed seat and the upper connecting seat are firmly connected respectively, and the lower fixed seat and the lower connecting seat are firmly connected respectively, thereby completing all the installation and fixing of the dust-proof bushing on the shock absorber.

[0043] In an alternative embodiment, the shock absorber further includes a connecting head, which includes an upper connecting head and a lower connecting head. The upper connecting head is fixedly connected to the upper connecting seat, and the lower connecting head is fixedly connected to the lower connecting seat. The connecting head is used to fix the shock absorber on the vehicle suspension system and the vehicle frame to ensure that the shock absorber can be correctly installed and work stably. Specifically, the upper connecting head is usually connected to the vehicle body or the vehicle frame to provide a fixed point; while the lower connecting head is usually connected to the suspension arm or the axle to provide another fixed point.

[0044] In addition, in the second embodiment of the present utility model, an automobile is provided, which includes the shock absorber with a dust-proof bushing in the above-mentioned first embodiment.

[0045] In the embodiment, in combination with the embodiment of the shock absorber with a dust-proof bushing, when the dust-proof bushing is installed on the shock absorber body, it is connected through the bushing connecting member and the dust-proof bushing, and then the bushing connecting member is fixedly connected to the fixed seat on the shock absorber through bolts. This structure is used to replace the existing fixing method of directly locking the bushing with a clamp. In this structure, the dust-proof bushing is connected to the upper fixed seat and the lower fixed seat respectively through the fixing rings at both ends. The first thread on the inner wall of the fixing ring is tightly engaged with the second thread on the outer wall of the connecting ring for fixed connection. And because the height of the connecting ring is greater than the height of the fixing ring, after the first thread and the second thread are connected, the first connecting buckle at the bottom of the first thread is matched and fastened with the second connecting buckle at the edge position of the connecting ring to complete the installation of the dust-proof bushing. Then, the dust-proof bushing together with the bushing connecting member is sleeved on the piston rod of the shock absorber. Finally, the connecting hole structures on the upper and lower fixed seats are respectively connected and fixed with the connecting holes on the upper and lower connecting seats through screws, and finally the upper and lower connecting seats are rotatably fixed to the corresponding positions of the shock absorber, thereby completing the installation and fixing of the dust-proof bushing. Such a connection structure can avoid the problem that the existing dust-proof bushing is directly locked by a clamp, resulting in friction between the bushing and the clamp in a vibration scenario, causing wear at the connection between the bushing and the clamp, and even loosening and falling off of the bushing, playing a role in protecting the dust-proof bushing and improving the fixing effect of the dust-proof bushing.

[0046] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
