Description

Technical Field

[0001] The invention belongs to the field of automobile shock absorbers, and in particular relates to an intelligent automobile shock absorber. Background Art

[0002] Automobile shock absorbers are the core components of the automobile suspension system and are vibration damping devices. Their main function is to attenuate vibrations caused by road impacts, improving ride smoothness and handling safety. They convert mechanical energy into heat energy through hydraulic or gas damping, reducing resistance during the suspension compression stroke to cushion impacts, and increasing resistance during the extension stroke to suppress rebound and ensure wheel grip.

[0003] However, when the existing automobile shock absorber is actually used, its shock absorbing component is exposed on the outer surface. Over time, it will cause the outer surface of the dynamic shock absorber to be covered with stains, which will affect the service life of the shock absorber. At the same time, when the car moves violently, the vibration amplitude of the shock absorber is too large, which will cause damage to the shock absorber and reduce the service life of the shock absorber.

[0004] Therefore, a smart automobile shock absorber is needed to solve the above-mentioned problems. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an intelligent automobile shock absorber, which effectively solves the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an intelligent automobile shock absorber, comprising a top plate, a bottom plate, a shock-absorbing spring and a hydraulic cylinder, wherein the bottom of the top plate is fixedly connected to the hydraulic cylinder, the telescopic end of the hydraulic cylinder is fixedly connected to the bottom plate, the bottom of the top plate is located on the outside of the hydraulic cylinder and is fixedly connected to the shock-absorbing spring, the side of the top plate is fixedly connected to a hydraulic rod, the fixed end of the hydraulic rod is provided with a limiting component, and the outside of the hydraulic cylinder is provided with a control component.

[0007] As a further solution of the present invention, the fixed end of the hydraulic rod is fixedly connected to the top plate, and the telescopic end of the hydraulic rod is fixedly connected to the bottom plate.

[0008] As a further solution of the present invention, the control component includes a first electrode sheet, a second electrode sheet, a power supply and a PLC controller. The fixed end of the hydraulic cylinder is fixedly connected to the second electrode sheet, and the telescopic end of the hydraulic cylinder is fixedly connected to the first electrode sheet. The two ends of the first electrode sheet and the second electrode sheet are electrically connected to the positive and negative poles of the power supply respectively, and the first electrode sheet is electrically connected to the PLC controller.

[0009] As a further solution of the present invention, the bottom of the top plate is fixedly connected to a sleeve 1, and the top of the bottom plate is fixedly connected to a sleeve 2.

[0010] As a further solution of the present invention, the inner wall of the second sleeve fits with the outer wall of the first sleeve, and the inner wall of the second sleeve and the outer wall of the first sleeve are both smooth.

[0011] As a further solution of the present invention, the limiting component includes a rubber sleeve, a friction sleeve, a through hole and piezoelectric ceramics. The fixed end of the hydraulic rod is fixedly connected to the friction sleeve, the inner wall of the friction sleeve is opened with a through hole, the outer wall of the friction sleeve is sleeved with a rubber sleeve, and the inner wall of the rubber sleeve is sleeved with piezoelectric ceramics.

[0012] As a further solution of the present invention, the rubber sleeve is fixedly connected to the fixed end of the hydraulic rod, and the end of the piezoelectric ceramic is in contact with the friction sleeve.

[0013] As a further solution of the present invention, the piezoelectric ceramic is electrically connected to the PLC controller. When the piezoelectric ceramic is energized, its volume will expand, thereby squeezing the friction sleeve.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, the second electrode sheet contacts the first electrode sheet, thereby connecting the circuit and transmitting current to the PLC controller. Subsequently, the piezoelectric ceramic expands, and the friction sleeve hinders the movement of the telescopic end of the hydraulic rod, thereby avoiding excessive vibration amplitude of the shock absorber, ensuring the normal use of the shock absorber, and improving the service life of the shock absorber.

[0016] 2. The present invention prevents the shock-absorbing spring and the hydraulic cylinder from being exposed to the outside world by wrapping the hydraulic cylinder and the shock-absorbing spring inside. At the same time, the sleeve 1 can slide along the inner wall of the sleeve 2, thereby not hindering the contraction of the shock-absorbing spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Embodiment 1, by Figure 1-5 The present invention discloses an intelligent automobile shock absorber, comprising a top plate 1, a bottom plate 2, a shock-absorbing spring 7 and a hydraulic cylinder 8. The bottom of the top plate 1 is fixedly connected to the hydraulic cylinder 8, the telescopic end of the hydraulic cylinder 8 is fixedly connected to the bottom plate 2, the bottom of the top plate 1 is located on the outside of the hydraulic cylinder 8 and is fixedly connected to the shock-absorbing spring 7, the side of the top plate 1 is fixedly connected to a hydraulic rod 3, the fixed end of the hydraulic rod 3 is fixedly connected to the top plate 1, and the telescopic end of the hydraulic rod 3 is fixedly connected to the bottom plate 2;

[0026] The fixed end of the hydraulic rod 3 is provided with a limiting assembly 4, which includes a rubber sleeve 41, a friction sleeve 42, a through hole 43, and a piezoelectric ceramic 44. The fixed end of the hydraulic rod 3 is fixedly connected to the friction sleeve 42, the inner wall of which is opened with a through hole 43. The outer wall of the friction sleeve 42 is sleeved with a rubber sleeve 41, and the inner wall of the rubber sleeve 41 is sleeved with a piezoelectric ceramic 44. The rubber sleeve 41 is fixedly connected to the fixed end of the hydraulic rod 3, and the end of the piezoelectric ceramic 44 is in contact with the friction sleeve 42.

[0027] The piezoelectric ceramic 44 is electrically connected to the PLC controller. When the piezoelectric ceramic 44 is energized, its volume will expand, thereby squeezing the friction sleeve 42 .

[0028] Example 2: Figure 1-5 It is given that a control component is provided on the outside of the hydraulic cylinder 8, and the control component includes a first electrode sheet 9, a second electrode sheet 10, a power supply and a PLC controller. The fixed end of the hydraulic cylinder 8 is fixedly connected to the second electrode sheet 10, and the telescopic end of the hydraulic cylinder 8 is fixedly connected to the first electrode sheet 9. The two ends of the first electrode sheet 9 and the second electrode sheet 10 are electrically connected to the positive and negative poles of the power supply respectively, and the first electrode sheet 9 is electrically connected to the PLC controller;

[0029] The bottom of the top plate 1 is fixedly connected with a sleeve 1 5, and the top of the bottom plate 2 is fixedly connected with a sleeve 2 6;

[0030] The inner wall of sleeve 2 6 fits with the outer wall of sleeve 1 5 , and both the inner wall of sleeve 2 6 and the outer wall of sleeve 1 5 are smooth.

[0031] Working principle: When the automobile shock absorber is in use, the hydraulic cylinder 8 and the shock-absorbing spring 7 play a role in cushioning. Under the connection of the sleeve 1 5 and the sleeve 2 6, the hydraulic cylinder 8 and the shock-absorbing spring 7 are wrapped inside, preventing the shock-absorbing spring 7 and the hydraulic cylinder 8 from being exposed to the outside world. At the same time, the sleeve 1 5 can slide along the inner wall of the sleeve 2 6, thereby not hindering the contraction of the shock-absorbing spring 7.

[0032] At the same time, the setting of the hydraulic rod 3 can enhance the cushioning effect of the shock absorber;

[0033] When the car moves violently, the vibration amplitude in the shock absorber will increase, causing the second electrode sheet 10 to contact the first electrode sheet 9, thereby connecting the circuit and transmitting current to the PLC controller. Subsequently, the piezoelectric ceramic 44 will expand, thereby squeezing the friction sleeve 42, increasing the friction between the friction sleeve 42 and the telescopic end of the hydraulic rod 3, thereby preventing the contraction of the telescopic end of the hydraulic rod 3, ensuring that the shock absorber is not over-compressed, thereby ensuring that the shock absorber can be used normally;

[0034] The friction sleeve 42 blocks the movement of the telescopic end of the hydraulic rod 3, thereby preventing the vibration amplitude of the shock absorber from being too large, ensuring the normal use of the shock absorber, and increasing the service life of the shock absorber.
