Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, and more specifically to an automobile shock absorber. Background Art

[0002] Automobile shock absorbers, also known as shock absorbers or vibration absorbers, are important components installed in the automobile suspension system. Their main function is to reduce the vibration and impact caused by uneven road surfaces, bumps and suspension system movement during driving. They eliminate or reduce the vibration of the vehicle by controlling the elastic changes and damping effects of the suspension system, so that the vehicle body can maintain a relatively stable posture.

[0003] A Chinese patent publication number CN219692121U discloses a split shock absorber. When the shock absorber is performing shock absorption, the piston rod slides in the cylinder, the cylinder is filled with mechanical oil, the oil storage tank is filled with part of the mechanical oil, and the end of the oil storage tank away from the baffle is filled with nitrogen. The gas can be compressed, so that when the piston assembly is pressed down, the gas is compressed, and part of the mechanical oil enters the oil storage tank through the through hole b. When the piston assembly moves upward, the mechanical oil enters the cylinder from the through hole a, the flow rate of the mechanical oil is slowed down, and the sliding speed of the piston rod is further slowed down, reducing the rebound times of the spring a, thereby reducing the vibration.

[0038] The shock absorbers of a car are all located on the suspension below the chassis. When the car is running, mud and sand on the ground will splash onto the shock absorbers. Therefore, dust covers need to be installed to prevent rainwater and mud and sand from invading the hydraulic cylinder inside the shock absorber and causing damage. Traditional shock absorber dust covers are located between the coil spring and the piston rod of the shock absorber. Therefore, when replacing the dust covers, the entire car needs to be propped up with a jack, and then the wheels, wheel hubs and brake calipers need to be removed before the shock absorbers can be removed and the dust covers can be replaced. At the same time, the dust covers are consumables, so they need to be replaced every once in a while, but removal is time-consuming and labor-intensive, which causes the inconvenience of replacing the dust covers.

[0039] Based on this, the problem in the related art that the entire shock absorber needs to be disassembled before the dust cover can be replaced can be improved. The shock absorber is connected to the chassis suspension of the car, so disassembly is time-consuming and laborious, which causes the inconvenience of replacing the dust cover.

[0040] See also Figure 1-Figure 6 A car shock absorber comprises a shock absorber body 1 and two corrugated protective sleeves 6, the outer ends of the shock absorber body 1 are respectively fixedly connected with mounting blocks 1 2 and 2 3, two connecting rings 1 4 are arranged between the mounting blocks 1 2 and 2 3, and two connecting rings 2 5 are arranged between the mounting blocks 1 2 and 2 3, and a connecting assembly 8 is arranged at the outer end of the connecting ring 2 5, the connecting assembly 8 comprises a driving block 88 and two movable blocks 87, both sides of the driving block 88 are provided with inclined surfaces, the two movable blocks 87 are respectively located on both sides of the driving block 88, the outer sides of the two movable blocks 87 are provided with inclined surfaces adapted to the driving block 88, the inclined surface of the driving block 88 is fixedly connected with a slider 89, the inclined surface of the movable block 87 is provided with a slide groove adapted to the slider 89, and the slider 89 is slidably connected to the slide groove.

[0041] Two ends of the corrugated protective sleeve 6 are respectively fixedly connected to two connecting rings 1 4 , and two ends of another corrugated protective sleeve 6 are respectively fixedly connected to two connecting rings 2 5 . The corrugated protective sleeve 6 is made of rubber material.

[0042] The outer ends of the connecting ring 1 4 and the connecting ring 2 5 are fixedly connected to two fixing frames 7, and the outer ends of the plurality of fixing frames 7 are all provided with bolt holes.

[0043] The upper and lower ends of the shock absorber body 1 in the present scheme are respectively fixed with mounting blocks 1 2 and 2 3, which are mainly used to abut against connecting rings 1 4 and 2 5 so that the corrugated protective sleeve 6 can be installed in the middle. The connecting rings 2 5 and 1 4 have the same shape and size, which are semicircular rings and can fit each other. The top and bottom ends of one corrugated protective sleeve 6 are fixed on the two connecting rings 1 4, and the other corrugated protective sleeve 6 is similarly fixed between the two connecting rings 2 5, so that the corrugated protective sleeve 6 can be installed on the outer side of the shock absorber body 1 instead of at the outer end of the piston rod. There is no need to remove the entire shock absorber during installation, which not only reduces the difficulty of replacement, but also saves labor costs and improves the efficiency of replacement.

[0044] During installation, it is first necessary to align the two corrugated protective sleeves 6 around the outer cover of the shock absorber body 1 so that the connecting ring 1 4 and the connecting ring 2 5 are aligned. Since half of the connecting assembly 8 is installed on the connecting ring 1 4 and the connecting ring 2 5 respectively, the two-part connecting assembly 8 is mainly through magnetic attraction, so that the driving block 88 drives the two movable blocks 87 to move, so that the claw 85 clamps the clamping block 82, so that the connecting ring 1 4 and the connecting ring 2 5 can be temporarily fixed and connected when they are aligned, so that the user does not need to hold the corrugated protective sleeve 6 all the time when using bolts to reinforce, thereby improving the convenience of installation. A fixing frame 7 is fixed on each connecting ring 1 4 and the connecting ring 2 5. By using bolts to connect the fixing frames 7 on the connecting ring 1 4 and the connecting ring 2 5 together, the installation of the corrugated protective sleeve 6 can be completed. Compared with the traditional method of removing the entire shock absorber to replace the corrugated protective sleeve 6, the convenience of replacement can be improved, the labor cost of maintenance can be saved for the user, and the economy is improved.

[0045] Optionally, in some embodiments, see Figure 2-Figure 6 The connecting assembly 8 also includes a shell 81, the outer end of the shell 81 is fixedly connected to the connecting ring 4, the inner wall of the shell 81 is fixedly connected to a clamping block 82, and the outer end of the clamping block 82 is fixedly connected to a magnetic block 83.

[0046] The connecting assembly 8 also includes a shell 84, the outer end of which is fixedly connected to the connecting ring 5, and the driving block 88 and the movable block 87 are both located inside the shell 84. A magnet compatible with the magnetic block 83 is installed on the outer end of the driving block 88, and the magnetic block 83 penetrates the shell 84 and extends to the inside.

[0047] The outer end of the movable block 87 is fixedly connected to a connecting rod 86, and the outer end of the shell 84 is provided with two movable holes 812. The connecting rod 86 passes through the movable holes 812. The end of the connecting rod 86 away from the movable block 87 is fixedly connected to a claw 85, and both sides of the block 82 are provided with a slot adapted to the claw 85.

[0048] The inner wall of the shell 2 84 is fixedly connected with a plurality of limit blocks 1 810, and the inner wall of the shell 2 84 is fixedly connected with two limit blocks 2 811, the outer end of the movable block 87 is slidably connected to the limit block 1 810, and the outer end of the movable block 87 is slidably connected to the inner wall of the shell 2 84, and the outer end of the driving block 88 is slidably connected to the limit block 2 811 via the sliding block.

[0049] The connecting assembly 8 in this scheme is mainly used to temporarily fix the connecting ring 1 4 and the connecting ring 2 5 when they are aligned, so that the user does not need to hold the corrugated protective sleeve 6 all the time when fastening the connecting ring 1 4 and the connecting ring 2 5 with bolts, thereby improving the convenience of installation. The shell 1 81 is fixed on the connecting ring 1 4, and the shell 2 84 is fixed on the connecting ring 2 5. The shell 1 81 is hollow on the side facing the shell 2 84, and a clamping block 82 is fixed inside it. A magnetic block 83 is fixed at the outer end of the clamping block 82. The magnetic block 83 can be made of iron so that it can be attracted by the magnet installed on the driving block 88. A through hole is opened on the shell 2 84 for the magnetic block 83 to enter its interior. The driving block 88 and two movable The movable block 87 and the driving block 88 are provided with an inclined surface on one side that contacts the movable block 87, which matches the inclined surface provided on the movable block 87. The movable block 87 is slidably connected to the slider 89 on the driving block 88 through the sliding groove provided on the inclined surface. The two movable blocks 87 are symmetrically distributed. At the same time, in order to increase the stability of the movable block 87 during movement, the upper and lower sides of the movable block 87 are slidably connected to the limit block 1 810 fixed inside the shell 2 84, and the back side of the movable block 87 is slidably connected to the inner wall of the shell 2 84 through a sliding bar. Through the multi-faceted sliding connection, the stability of the movable block 87 can be increased while limiting it to lateral movement. The driving block 88 is slidably connected to the limit block 2 811 fixed to the inner wall of the shell 2 84 through the sliding blocks installed on the upper and lower sides.

[0050] When the shell 2 84 slides into the interior of the shell 1 81, the magnetic block 83 will first pass through the through hole into the interior of the shell 2 84, and the clamping block 82 will be blocked outside and abut against the outer surface of the shell 2 84. At this time, the magnetic block 83 is attracted to the magnet on the driving block 88, and the driving block 88 will move toward the magnetic block 83 so that they are adsorbed together. At this time, the movable block 87 is slidably connected to the inclined surface of the driving block 88, so the two movable blocks 87 will approach each other. A connecting rod 86 is fixed on the movable block 87, and the connecting rod 86 passes through the movable hole 812 and is installed with a claw 85. Therefore, the claw 85 is driven by the movable block 87 to be stuck in the groove on the clamping block 82, so that the connecting ring 1 4 and the connecting ring 2 5 can be temporarily fixed and connected when they are aligned.

[0051] Working principle: When the device is used to replace the corrugated protective sleeve 6, first, the two corrugated protective sleeves 6 need to be aligned and covered on the outer periphery of the shock absorber body 1, so that the connecting ring 1 4 and the connecting ring 2 5 are matched, the shell 1 81 is fixed on the connecting ring 1 4, and the shell 2 84 is fixed on the connecting ring 2 5. The shell 1 81 is hollow on the side facing the shell 2 84. When the shell 2 84 slides into the interior of the shell 1 81, the magnetic block 83 will first pass through the through hole into the interior of the shell 2 84. The magnetic block 83 and the magnet on the driving block 88 will attract each other, which will cause the driving block 88 to move toward the magnetic block 83. At this time, the two movable blocks 87 will approach each other. Therefore, through the drive of the movable block 87, the claw 85 will be stuck in the groove on the clamping block 82, so that the connecting ring 1 4 and the connecting ring 2 5 can be temporarily fixed and connected when aligned, and then the fixing frame 7 on the connecting ring 1 4 and the connecting ring 2 5 is connected together by bolts to complete the installation of the corrugated protective sleeve 6.

[0052] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
