Abstract
Description
Technical Field
[0001] The utility model relates to a shock absorber, in particular to a shock absorber which is convenient for heat dissipation and belongs to the technical field of shock absorbers. Background Art
[0002] Shock absorbers are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the smoothness of the car's ride. When passing over uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump. The car's shock absorption system is composed of springs and shock absorbers. The shock absorber is not used to support the weight of the car body, but to suppress the shock when the spring rebounds after shock absorption and absorb the energy of road impact. When the vehicle is driving on a bumpy road, the piston rod in the shock absorber continuously retracts and contracts in the cylinder, and the shock-absorbing oil in the cylinder continuously flows back and forth, buffering the impact force, reducing the degree of bumps, playing a shock-absorbing role, and increasing the stability of the vehicle's driving.
[0003] Common shock absorbers usually have an oil pressure structure inside the damper. In order to ensure the stability of the damper, a dust cover is usually installed on the outer surface of the shock absorber. During the use of the shock absorber, a closed space will be formed between the dust cover, which will affect the heat dissipation effect and have a bad impact on the shock absorber.

[0024] The embodiment of the utility model provides a shock absorber which is convenient for heat dissipation.
[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , cylinder body 1 and piston rod 2, the piston rod 2 is slidably connected to the cylinder body 1, an upper spring seat 3 and a lower spring seat 4 are respectively fixed to the top end of the piston rod 2 and the bottom end of the cylinder body 1, a shock-absorbing spring 5 is fixedly connected between the upper spring seat 3 and the lower spring seat 4, and a support ring 6 is installed on the outer surfaces of the upper spring seat 3 and the lower spring seat 4, and a vertical plate 7 is installed on the side where the two support rings 6 are close to each other, a dust cover 8 is installed between the two vertical plates 7, and a heat dissipation port is opened on the outer surface of the dust cover 8, and a dustproof net 9 is installed in each heat dissipation port, and openings distributed equidistantly are opened on the outer sides of the two vertical plates 7, an exhaust check valve 10 is installed at the opening position of the upper vertical plate 7, and an intake check valve 11 is installed at the opening position of the lower vertical plate 7.
[0026] Please refer to Figure 1 , Figure 2 and Figure 4 The size of the opening of the vertical plate 7 is larger than the size of the heat dissipation port, which is beneficial to the overall stable heat dissipation and improves the heat dissipation efficiency of the dust cover 8. The exhaust check valve 10 is only opened during exhaust, and the intake check valve 11 is only opened during intake, which is beneficial to the stability of the intake check valve 11 and the exhaust check valve 10, thereby maintaining the overall stability.
[0027] Please refer to Figure 1 , Figure 2 and Figure 4The sides of the upper spring seat 3 and the lower spring seat 4 are provided with slots, and the inner sides of the two support rings 6 are provided with grooves. The inner wall of each groove is slidably connected with an insertion rod 12, and each insertion rod 12 is plugged into the slots close to each other, which is beneficial to the stability of the insertion rod 12. The support ring 6 can be limited by plugging the insertion rod 12 into the slot, and the other end of each insertion rod 12 is fixedly connected to a limiting plate 13, and the other side of each limiting plate 13 is fixedly connected with an auxiliary spring 14, and the right side of each limiting plate 13 is fixedly connected with an auxiliary rod 15, and each auxiliary rod 15 passes through the support ring 6. Moving the auxiliary rod 15 is beneficial to the stable disassembly of the insertion rod 12, and then it is convenient to replace the dust cover 8.
[0028] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A chamber is provided on the side of the upper spring seat 3 and the lower spring seat 4 away from each other, and a baffle 16 is fixedly connected to the inner bottom wall of each chamber. A lifting ring 17 is installed on the side of the two baffles 16 away from each other, which is conducive to the stability of the lifting ring 17. The whole can be connected to the outside world through the lifting ring 17. A groove matching the shock-absorbing spring 5 is provided at the bottom end of the upper spring seat 3 and the top end of the lower spring seat 4. A limiting rubber ring 18 matching the shock-absorbing spring 5 is fixed on the inner wall of the groove, which is conducive to the stability of the shock-absorbing spring 5, thereby maintaining the stability of the whole.
[0029] When the utility model is in use: when the vibration occurs and the whole is compressed and reset, the sliding between the piston rod 2 and the cylinder body 1 generates high temperature and dissipates it, causing the internal temperature of the dust cover 8 to increase. As the dust cover 8 is compressed and reset, the internal hot air leaves from the heat dissipation port, and the external air enters into the dust cover 8 from the heat dissipation port.
[0030] At the same time, when the whole is reset, the air pressure inside the dust cover 8 is lower than the external air pressure, and the external air enters the dust cover 8 from the air intake check valve 11. Since the size of the opening of the vertical plate 7 is larger than the size of the heat dissipation port, the air intake volume of the air intake check valve 11 is greater than the air intake volume of the heat dissipation port. When compression occurs, the air pressure inside the dust cover 8 is greater than the external atmospheric pressure, and the internal air leaves the dust cover 8 from the exhaust check valve 10. Since the exhaust volume of the exhaust check valve 10 is greater than the exhaust volume of the heat dissipation port, the proportion of hot air leaving from the exhaust check valve 10 is relatively large, thus forming a flow route in which the air flow enters from the air intake check valve 11 and is discharged from the exhaust check valve 10, so that convection is formed between the air inside and outside the dust cover 8, which is convenient for heat dissipation inside the dust cover 8 and solves the problem of poor heat dissipation effect of the shock absorber in the prior art.
[0031] During normal use, the insertion rod 12 is inserted in the slot to maintain the stability of the support ring 6. When the dust cover 8 is damaged and needs to be replaced, the auxiliary rod 15 is pulled to drive the insertion rod 12 to leave the slot so that the insertion rod 12 is released from the limit, and then the support ring 6 can be separated from the upper spring seat 3 and the lower spring seat 4, which is convenient for replacing the dust cover 8.
[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
