Description

Technical Field

[0001] The utility model relates to the field of shock absorbing equipment, in particular to a coilover shock absorber. Background Art

[0002] A coilover shock absorber is a shock absorber that can adjust the spring expansion and contraction, shock absorber body and shock absorber damping. The height adjustment is completed through a coilover ring (that is, the outer periphery of the ring is toothed).

[0003] When installing a coilover shock absorber, first ensure that the shock absorber assembly is returned to its original position, and then use the top mounting plate to connect it to the vehicle structure. Tightening the bolts is the core step, and it is necessary to ensure that the connection surface fits tightly. The existing method may be difficult to control the positioning by manual pressing alone. When installing the bolts, gaps are easily generated due to displacement, resulting in an unstable connection, thereby affecting the overall use effect. For this reason, a coilover shock absorber is proposed. Utility Model Content

[0004] In response to the deficiencies in the prior art, the present invention provides a coilover shock absorber, in which external slots are opened around the outside of a mounting top plate, and a stabilizing tube with a magnetic convex layer is installed in the external slot, so that the upper end surface of the magnetic convex layer is flush with the upper end surface of the mounting top plate. Therefore, when the mounting top plate is fitted to the vehicle structure, the magnetic convex layer and the structure on the vehicle are attracted to each other, positioning the mounting top plate while avoiding manual pressure that causes the connection surface to be out of fit, resulting in a gap during subsequent installation. At the same time, the mounting top plate is made more stable after connection, thereby improving the overall use effect.

[0005] In order to solve the above technical problems, the present invention solves the problem that when the coilover shock absorber is installed with bolts, a gap is easily generated due to displacement, resulting in an unstable connection through the following technical solution.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A coilover shock absorber includes a mounting top plate arranged on the coilover shock absorber assembly. The coilover shock absorber assembly is provided with external slots with stabilizing tubes on all four sides. The upper end surface of the stabilizing tube is provided with a magnetic convex layer and is flush with the mounting top plate.

[0008] Preferably, the external slot is configured to be arc-shaped and the stabilizing tube is glued therein, and the lower end surface of the stabilizing tube extends to the outside of the external slot.

[0009] Preferably, an inner support rod with an outer sleeve is provided below one of the stabilizing cylinders, the inner support rod can move along the inside of the outer sleeve, and an extrusion spring is provided between the inner support rod and the outer sleeve.

[0010] Preferably, one end of the extrusion spring is connected to the inner wall of the inner support rod, and the other end is connected to the outer sleeve, and the extrusion spring can be wrapped around the shaft of the inner support rod.

[0011] Preferably, a movable supporting base plate is provided at the bottom of the outer sleeve, and openings are provided at the four corners of the supporting base plate.

[0012] Preferably, a card insertion rod is installed on the top of the supporting base plate and can be inserted into it by the bottom of the outer sleeve.

[0013] Preferably, the top of the inserting rod is connected to a stable rod head with elasticity to squeeze the inner wall of the outer sleeve, and the lower end of the inner wall of the outer sleeve is connected to a positioning inner plate for limiting position.

[0014] Preferably, a clamping piece is provided at one end outside the inner support rod and its opening is clamped on the coilover shock absorber assembly, an outer limiting cylinder is connected to the outside of the outer sleeve, and a movable sleeve is connected to one end of the clamping piece facing the outer limiting cylinder and is sleeved thereon for movement.

[0015] Preferably, a section of thread is provided on the lower portion of the outer wall of the stabilizing tube, a section of thread is provided on the upper portion of the inner support rod, and an installation kit is provided between the threads on the stabilizing tube and the inner support rod.

[0016] Preferably, the top of the inner support rod is connected to an end plate and can move inside the stabilizing tube, and the top of the end plate is provided with a round convex pad that contacts the top of the inner wall of the stabilizing tube.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The coilover shock absorber provided in the present application is provided with external slots around the outside of the mounting top plate, and a stabilizing tube with a magnetic convex layer is installed in the external slot, so that the upper end surface of the magnetic convex layer is flush with the upper end surface of the mounting top plate. Therefore, when the mounting top plate is fitted with the vehicle structure, the magnetic convex layer is attracted to the structure on the vehicle, and while positioning the mounting top plate, it avoids the connection surface being out of fit due to manual pressing, which causes a gap in the subsequent installation. At the same time, it also makes the mounting top plate more stable after connection, thereby improving the overall use effect.

[0019] The present application sets an outer sleeve, an inner support rod and an extrusion spring. The inner support rod can move up and down inside the outer sleeve. An extrusion spring with elastic force is installed between the outer sleeve and the inner support rod to adjust the distance, thereby preventing the coilover shock absorber assembly from being difficult to fix as a whole during installation, resulting in left and right deviation problems.

[0020] The present application provides a support base plate to further increase the contact area when the outer sleeve is in contact with the ground, thereby making the support surface more stable.

[0021] The present application provides a card insertion rod, which is fixedly installed in the middle of the top end of the support base plate so that it can be inserted into the bottom opening of the outer sleeve, thereby facilitating the disassembly, assembly and replacement of the support base plate according to needs.

Therefore, the above terms should not be understood as limitations on the present invention.

[0033] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0034] See also Figure 1 - Figure 6 A coilover shock absorber includes a mounting top plate 101 arranged on a coilover shock absorber assembly 1. The coilover shock absorber assembly 1 is provided with an external slot 2 with a stabilizing tube 3 on all four sides. The upper end surface of the stabilizing tube 3 is provided with a magnetic convex layer 301 and is flush with the mounting top plate 101.

[0035] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 6The coilover shock absorber of the present application is mainly composed of a coilover shock absorber assembly 1 and a mounting top plate 101 and other structural combinations, wherein the mounting top plate 101 is arranged on the top of the coilover shock absorber assembly 1. When ensuring that the coilover shock absorber assembly 1 is returned to its original position, the mounting top plate 101 is used to connect with the vehicle structure. The main structural material of the vehicle is usually metal, such as iron, steel, etc. Therefore, an external slot 2 is provided around the outside of the mounting top plate 101, and a stabilizing tube 3 with a magnetic convex layer 301 is installed in the external slot 2, so that the stabilizing tube 3 and the magnetic convex layer 301 are connected. After layer 301 is installed, the upper end surface of the magnetic protrusion 301 is flush with the upper end surface of the mounting top plate 101. Therefore, when the mounting top plate 101 is fitted with the vehicle structure, the magnetic protrusion 301 composed of magnets is attracted to the structure on the vehicle, positioning the mounting top plate 101 while avoiding the problem of gaps caused by improper manual pressure control resulting in the connection surface not being in a tight state during the subsequent installation process. At the same time, it also makes the mounting top plate 101 more stable after connection, thereby improving the overall use effect.

[0036] It should also be noted that the curvature set inside the external slot 2 just makes the outer wall of the stabilizing tube 3 fit tightly, and the two are glued to facilitate subsequent disassembly; the magnetic protrusion 301 can be connected to the stabilizing tube 3 by gluing, which is convenient for subsequent replacement of the material of the magnetic protrusion 301 according to the requirements of the vehicle structure, so that the two can contact each other.

[0037] See also Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In this application, an outer sleeve 5, an inner support rod 501 and an extrusion spring 502 are also provided, wherein the inner support rod 501 can move up and down inside the outer sleeve 5, and an elastic extrusion spring 502 is installed between the outer sleeve 5 and the inner support rod 501 to adjust the spacing, and the outer sleeve 5 and the inner support rod 501 are vertically installed on the stabilizing cylinder 3, so that when the mounting top plate 101 is fitted with the vehicle structure, the outer sleeve 5 is driven to support it on the ground, thereby further positioning the mounting top plate 101 while preventing the coilover shock absorber assembly 1 from being difficult to fix as a whole during installation, resulting in left and right deviation problems.

[0038] It should also be noted that by moving the outer sleeve 5 upward, the inner support rod 501 can be driven to move therein. After squeezing the extrusion spring 502 provided between the two, the overall height between the outer sleeve 5 and the inner support rod 501 can be adjusted. The elastic force of the extrusion spring 502 itself can drive the outer sleeve 5 to be squeezed on the ground or other positions for support.

[0039] In the present application, a supporting base plate 4 is also provided to further increase the contact area when the outer sleeve 5 is in contact with the ground, etc., so as to make the supporting surface more stable.

[0040] The present application also provides a card insertion rod 401, which is fixedly mounted in the middle of the top end of the support base plate 4 so that it can be inserted into the bottom opening of the outer sleeve 5, thereby facilitating the disassembly, assembly and replacement of the support base plate 4 according to needs.

[0041] The present application also provides a stabilizing rod head 402 and a positioning inner plate 403. The stabilizing rod head 402 is elastic. When the card rod 401 is inserted into the outer sleeve 5 for installation, a greater friction force is generated between the stabilizing rod head 402 and the inner wall of the outer sleeve 5, thereby improving the stability of the connection between the card rod 401; the positioning inner plate 403 is installed on the inner tube wall of the outer sleeve 5. When the stabilizing rod head 402 is installed together with the card rod 401, the upper end face of the stabilizing rod head 402 can be fitted on the lower end face of the positioning inner plate 403, thereby limiting it.

[0042] The present application also provides a movable sleeve 7, a clamping member 701 and an outer limiting cylinder 6. After the coilover shock absorber assembly 1 and the mounting top plate 101 are vertically supported by the outer sleeve 5 and the inner support rod 501, the clamping member 701 is arranged on the outside of the outer sleeve 5. The clamping member 701 is elastic and can clamp the shaft rod part of the coilover shock absorber assembly 1 to obtain a certain support on the horizontal line, which is convenient for installing the side structure of the coilover shock absorber assembly 1 to other structural parts of the vehicle; the movable sleeve 7 and the clamping member 701 are an integrated structural design, and the outer limiting cylinder 6 is installed on the outer cylinder wall of the outer sleeve 5, so that after the outer limiting cylinder 6 is sleeved on the outside thereof, it can move up and down relatively and drive the clamping member 701 to move in the same direction with it, so as to adjust the clamping height of the clamping member 701.

[0043] The present application also provides an installation kit 8 for connecting the inner support rod 501 with the stabilizing tube 3, wherein the lower end portion of the outer tube wall of the supporting base plate 4 is provided with a section of thread that matches the inner thread of the installation kit 8, and the upper end of the outer axis of the inner support rod 501 is provided with a section of outer thread that matches the inner thread of the installation kit 8 tube. The section of thread on the inner support rod 501 allows the installation kit 8 to rotate relatively thereon and move up and down. After rotating upward, it drives the installation kit 8 to connect with the thread on the outer wall of the stabilizing tube 3, and installs the stabilizing tube 3 and the inner support rod 501. When disassembling, it only needs to reverse and move the installation kit 8 downward to separate the installation kit 8 from the stabilizing tube 3.

[0044] The present application also provides an end plate 801 and a round convex pad 802. The round convex pad 802 is made of rubber and is glued to the top of the end plate 801. The end plate 801 can move inside the stabilizing tube 3. When connecting the installation kit 8 and the stabilizing tube 3, the end plate 801 is pushed upward until the round convex pad 802 is in contact with the top of the inner wall of the stabilizing tube 3. This increases the friction of the contact surface and makes the connection between the inner support rod 501 and the stabilizing tube 3 more stable.

[0045] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as 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 demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
