Description

Technical Field

[0001] The present application relates to the field of automobile chassis system maintenance, and in particular to a disassembly and assembly wrench for an electronically controlled shock absorber. Background Art

[0002] Since most new energy vehicles use electronically controlled chassis, and electronically controlled shock absorbers are important components for improving chassis performance, adjusting the internal parts of electronically controlled shock absorbers has become an important means to improve chassis performance. The steps for adjusting the internal parts of electronically controlled shock absorbers generally include preparing electronically controlled shock absorber debugging tubes and preparing special disassembly and assembly wrenches. At present, the disassembly and assembly of adjustable electronically controlled shock absorbers usually rely on specially designed wrenches. Generally speaking, adjustable electronically controlled shock absorbers need to be equipped with screw covers on the basis of conventional electronically controlled shock absorbers, and special wrenches are used to loosen and tighten the screw covers to open or lock the adjustable electronically controlled shock absorbers.

[0003] There are basically two types of special wrenches commonly used in the industry. The first type of special wrench is a hexagonal wrench designed with a hexagonal screw cap. This screw cap is simple in design, but its protruding shape interferes with the installation of other accessories. In addition, because ordinary open-end wrenches can also open hexagonal screw caps, safety is not guaranteed, so round screw caps are now more commonly used. The second type of special wrench is used for round screw caps, and the round screw caps are screwed by locating pins. However, the locating pins and the wrench are welded and are very easy to break during use, which means that the wrench body cannot be reused, which is not conducive to cost control. In addition, the existing structure generally adopts a two-point positioning method, so if one of the locating pins breaks, the entire wrench cannot be used, which is easy to affect the progress of the project.

[0004] In summary, there is an urgent need for a special wrench with high availability and efficient disassembly and assembly for disassembling and assembling an adjustable electronically controlled shock absorber. Utility Model Content

[0005] In order to solve the above problems, the present application provides a disassembly and assembly wrench for an electronically controlled shock absorber, which significantly improves the availability of the disassembly and assembly wrench and makes the disassembly and assembly process more efficient and stable.

[0006] The present application provides a disassembly and assembly wrench for an electronically controlled shock absorber, which adopts the following technical solution:

[0007] A disassembly wrench for an electronically controlled shock absorber is adapted to a screw cap of the electronically controlled shock absorber, comprising a wrench positioning portion and a wrench handle connected to the wrench positioning portion for applying force, wherein the wrench positioning portion is provided with a plurality of positioning pin holes, the number of the positioning pin holes being at least three, any three of the plurality of positioning pin holes being sequentially connected end to end to form a closed pattern in the form of a triangle, the positioning pin hole matches the positioning pin, and the positioning pin is detachably connected to the positioning pin hole.

[0008] By adopting the above technical solution, at least three positioning pin holes are opened on the positioning part of the wrench. When the three positioning pins are matched, the triangular positioning pin structure will make the disassembly and assembly process more stable; when there are only two matching positioning pins, the positioning pins can also cooperate with the screw cap to realize the loosening or tightening of the screw cap; and the positioning pins are detachably connected to the positioning pin holes, even if one of the positioning pins is damaged, the positioning pin can be replaced and the wrench can continue to be used, thereby improving the utilization rate of the wrench and saving resource costs.

[0009] Preferably, a plurality of positioning holes are provided on the screw cover, and each positioning pin hole has a positioning hole corresponding thereto. When the positioning pin is detachably connected to the positioning pin hole, one end of the positioning pin protrudes beyond one side of the wrench positioning portion, and the protruding portion of the positioning pin contacts the positioning hole.

[0010] By adopting the above technical solution, the part of the locating pin protruding from the wrench locating part contacts the locating hole on the screw cap, and the rotation of the screw cap can be achieved through accurate positioning. The position of the locating pin hole corresponds to the locating hole, which has a certain degree of specificity and can prevent non-professionals from easily using other tools to twist the screw cap, causing safety hazards, thereby improving safety.

[0011] Preferably, the diameter of the portion of the positioning pin protruding from the wrench positioning portion is smaller than the diameter of the portion of the positioning pin not protruding from the wrench positioning portion and the diameter of the positioning hole.

[0012] By adopting the above technical solution, the diameter of the protruding part of the positioning pin is smaller than the diameter of the positioning hole, and there is a certain fault tolerance when positioning between the two. While ensuring the positioning effect, the wear of the positioning pin on the screw cover is reduced.

[0013] Preferably, there are at least two wrench handles, one end of each wrench handle is connected to the outside of the wrench positioning portion, and the wrench handle and the wrench positioning portion are integrally formed.

[0014] By adopting the above technical solution, the wrench handle and the wrench positioning portion are integrally formed, which can increase the overall strength of the wrench and enable it to maintain a certain stability when force is applied.

[0015] Preferably, there are two wrench handles, the two wrench handles are in the shape of long strips, and the two wrench handles are coaxially arranged.

[0016] By adopting the above technical solution and providing two opposite and coaxial wrench handles, the force applied to the wrench positioning part can be more uniform, thereby reducing the possibility of damage thereof.

[0017] Preferably, an open slot is provided through the wrench positioning portion for avoiding the upper connecting rod (8) of the electronically controlled shock absorber, and the slot width of the open slot is greater than the outer diameter of the connecting rod.

[0018] By adopting the above technical solution, an open groove is provided on the wrench positioning part, so that the wrench can effectively avoid the connecting rod of the electronically controlled shock absorber when in use, reducing interference during disassembly and assembly, facilitating operation and reducing damage to the connecting rod by the wrench positioning part.

[0019] Preferably, the opening groove includes a first groove and a second groove, the first groove is semicircular, the semicircular opening is connected to one end of the second groove, and the other end of the second groove is connected to the outside, and the groove width of the second groove is the groove width of the opening groove.

[0020] By adopting the above technical solution, the open groove is divided into sections. The first semicircular groove can accommodate the connecting rod, so that the wrench can rotate the nut without interfering with the connecting rod. The second groove can allow the connecting rod to directly enter the wrench positioning part, which can prevent the wrench positioning part from being inserted into the connecting rod from top to bottom and damaging the connecting rod.

[0021] Preferably, an anti-slip section is provided at one end of the wrench handle away from the wrench positioning portion.

[0022] Preferably, the surface of the anti-slip section is provided with anti-slip textures.

[0023] By adopting the above technical solution, the friction between the hand and the lever handle is increased, which effectively prevents the hand from slipping during use, and further improves the safety and convenience of operation.

[0024] In summary, this application has at least the following beneficial effects:

[0025] 1. The positioning pins on the positioning part of the wrench in the present application are arranged in a triangular shape, which enhances the stability of the structure and makes the use of the wrench more reliable. The triangular arrangement makes it possible to tighten or loosen the nut cover even if there are only any two positioning pins on the positioning part of the wrench, thereby ensuring the efficient use of the wrench.

[0026] 2. In the present application, a detachable connection is adopted between the locating pin and the locating part of the wrench, which facilitates the timely replacement of the damaged locating pin and avoids the wrench being scrapped along with the locating pin, thereby improving the service life and safety of the wrench and effectively saving cost resources.

[0027] 3. In the present application, the wrench positioning part and the handle are connected in one piece, which increases the overall strength and stability of the wrench.

[0028] 4. The present application adopts a method of combining a positioning pin with a positioning hole on the screw cover to realize the screwing of the screw cover, which is targeted at the screw cover and can prevent non-professionals from using other tools to open the screw cover of the electronically controlled shock absorber, thereby ensuring the safety of use.

Therefore, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features.

[0042] The present embodiment provides a disassembly wrench for an electronically controlled shock absorber, which is adapted to fit a screw cap 1 on the electronically controlled shock absorber. Figure 1 As shown, the screw cap 1 is tightened or loosened by a wrench, thereby achieving the purpose of adjusting the electronically controlled shock absorber.

[0043] like Figure 2 As shown, the disassembly and assembly wrench disclosed in this embodiment includes a wrench positioning portion 2 and a wrench handle 3 connected to the wrench positioning portion 2 for applying force.

[0044] The wrench positioning portion 2 is provided with a plurality of positioning pin holes 4, the number of which is at least three. Any three of the plurality of positioning pin holes 4 are sequentially connected end to end to form a closed pattern in the form of a triangle.

[0045] In this embodiment, the number of the positioning pin holes 4 is 3, and the three positioning pin holes 4 are connected end to end in sequence to form a closed pattern that is an equilateral triangle. Such a layout significantly enhances the stability of the structure.

[0046] In other specific implementations, the number of the positioning pin holes 4 can be 4, 5, etc., as long as any three of them can form a triangle, and the remaining solutions will not be described in detail.

[0047] like Figure 3 As shown, the locating pin hole 4 matches the locating pin 5. It should be noted that the number of locating pins 5 can be equal to the number of locating pin holes 4 or less than the number of locating pin holes 4, but the number of locating pin holes 4 is at least 2.

[0048] The positioning pin 5 is detachably connected to the positioning pin hole 4 .

[0049] In this embodiment, a thread is provided on the inner wall of the positioning pin hole 4, so the connection between the positioning pin 5 and the positioning pin hole 4 is a threaded hole connection. In other specific implementations, the detachable connection between the positioning pin 5 and the positioning pin hole 4 can also be a pin connection or a key connection, etc., so as to facilitate timely replacement of a damaged positioning pin 5.

[0050] like Figure 4 and Figure 5 As shown, a plurality of positioning holes 6 are provided on the screw cover 1 , and each positioning pin hole 4 has a corresponding positioning hole 6 .

[0051] During specific implementation, the number and positions of the positioning pin holes 4 can be adjusted accordingly according to the positioning holes 6 on the screw cover 1 to achieve the best positioning effect.

[0052] like Figure 3 As shown, when the positioning pin 5 is detachably connected to the positioning pin hole 4, one end of the positioning pin 5 protrudes out of one side of the wrench positioning portion 2, and the protruding portion of the positioning pin 5 contacts the positioning hole 6 to realize the rotation of the screw cap;

[0053] Combination Figure 5 As shown, the diameter of the protruding part of the locating pin 5 is smaller than the diameter of the locating hole 6, and the diameter of the part of the locating pin 5 protruding from the wrench locating part 2 is smaller than the diameter of the part of the locating pin 5 not protruding from the wrench locating part 2 and the diameter of the locating hole 6, so as to reduce the wear on the screw cover and provide a certain degree of fault tolerance.

[0054] like Figure 6 and Figure 7 As shown, the protruding portion is inserted into the positioning hole 6 and is clearance-matched with the positioning hole 6 .

[0055] There are at least two wrench handles 3 , one end of the wrench handle 3 is connected to the outside of the wrench positioning portion 2 , and the wrench handle 3 and the wrench positioning portion 2 are integrally formed.

[0056] In other specific implementations, the number of the wrench handles 3 can be 3, 4, etc., and the distance between two adjacent wrench handles 3 is equal. The one-piece design can enhance the overall structural strength of the wrench and avoid breakage or damage during use.

[0057] Furthermore, in this embodiment, if Figure 1 As shown, there are two lever handles 3 , the two lever handles 3 are in the shape of long strips, and the two lever handles 3 are coaxially arranged.

[0058] The long strip design makes the wrench as a whole easier to hold and apply force, thereby improving the convenience of use; at the same time, the relative coaxial setting between the two wrench handles 3 can also ensure that the wrench will not deflect or twist during the force application process, thereby ensuring the accuracy and safety of the operation.

[0059] An open slot 7 for avoiding the upper connecting rod 8 of the electronically controlled shock absorber is provided through the wrench positioning portion 2 , and the slot width of the open slot 7 is greater than the outer diameter of the connecting rod 8 .

[0060] like Figure 8 As shown, the opening groove 7 includes a first groove 71 and a second groove 72. The first groove 71 is semicircular. One end of the semicircular opening second groove 72 is connected, and the other end of the second groove 72 is connected to the outside. The groove width of the second groove 72 is the groove width of the opening groove 7.

[0061] like Fig. 9 As shown, the semicircular wall of the first groove 71 does not contact the connecting rod 8 on the electronically controlled shock absorber, and the diameter of the semicircular arc is equal to the width of the second groove 72. When the connecting rod 8 enters the first groove 71 of the wrench positioning portion 2 through the second groove 72, the outer surface of the connecting rod 8 and the inner wall of the second groove 72 also do not contact each other. Through this design, it can be ensured that when the wrench is used to disassemble and assemble the electronically controlled shock absorber, the connecting rod 8 will not interfere with or collide with the wrench, thereby ensuring the smooth operation.

[0062] An end of the wrench handle 3 away from the wrench positioning portion 2 is provided with an anti-slip section.

[0063] In this embodiment, if Figure 1 As shown, the surface of the anti-skid section is provided with anti-skid lines to increase the friction between the wrench handle 3 and the palm and prevent slipping during use. This design can further improve the safety and convenience of the wrench.

[0064] In other specific implementations, the anti-slip section may also be a rubber sleeve or the like which is sleeved on the handle 3 and has an anti-slip structure.

[0065] When using the present embodiment to disassemble the adjustable electronically controlled shock absorber, firstly, clamp the shock absorber with a bench vise, then align the positioning pin 5 of the present embodiment with the positioning hole 6 of the shock absorber screw cover 1 and insert it into the hole, then rotate the wrench handle 3 counterclockwise until the screw cover 1 is loose enough to be directly screwed by hand, and finally remove the wrench from the screw cover 1; remove the screw cover 1 from the shock absorber from bottom to top, and finally, the connecting rod 8 and the internal parts such as the solenoid valve can be taken out normally.

[0066] When using this embodiment to assemble the adjustable electronically controlled shock absorber: the steps are the reverse operation of the disassembly process until the screw cover 1 and the shock absorber are completely tightened, which will not be repeated here.

[0067] In summary, the disassembly and assembly wrench for the electronically controlled shock absorber of the present application significantly improves the safety, availability and ease of use of the wrench by adopting multiple technical means such as the design of multiple positioning pin holes 4, the detachable positioning pins 5, the integrally formed wrench handle 3 and the anti-slip treatment. These optimization measures work together to make the disassembly and assembly wrench of the present application have better use effect and higher practical value in actual application.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application. For example, different materials or features can be selected according to actual needs to replace part or all of the technical features in the above embodiments; the technical features in the above embodiments can also be combined or split to form a new technical solution. In short, any simple modification, equivalent replacement or improvement of the technical solution of the present application should be included in the protection scope of the present application.
