[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 5 As shown, a vehicle suspension buffer structure of the present invention comprises a buffer chamber 1 and a connecting arm 2, wherein the buffer chamber 1 is used to connect to the vehicle body, and the connecting arm 2 is used to connect to the engine; The buffer chamber 1 is provided with an oil storage chamber inside, and a side plate 3 and a piston 4 are provided in the oil storage chamber. The piston 4 is connected to the inner wall of the buffer chamber 1 through a first spring 5. The piston 4 is in the shape of a vertically flat square barrel. A horizontal piston 6 is vertically slidably provided in the piston 4. The horizontal piston 6 is connected to the inner wall of the piston 4 through a second spring 7. Among them, an opening is provided on the side wall of the buffer chamber 1, and the opening direction is perpendicular to the vertical plane where the side plate 3 is located. A sealing structure is provided in the opening, and the horizontal plug column 6 is connected to the connecting arm 2 through the sealing structure. The end surface of the horizontal plug column 6 facing the side plate 3 is coplanar with the end surface of the piston 4 facing the side plate 3. The horizontal plug column 6 divides the internal space of the piston 4 into two upper and lower first spaces, and the piston 4 divides the space in the buffer chamber 1 where it is located into two front and rear second spaces. The gap between the piston 4 and the side plate 3 and the gap between the horizontal plug column 6 and the side plate 3 are both used to limit the flow rate of the oil.

[0020] In detail, the automobile engine can be installed on the vehicle body through the connecting arm 2 and the buffer chamber 1. The structure in the buffer chamber 1 can have a buffering effect on the connecting arm 2, thereby having a buffering effect on the engine. The side plate 3 is mainly used to form a narrow gap between the piston 4 and the horizontal piston column 6. This gap can allow oil to flow. The two first spaces and the two second spaces are connected to the inside of the buffer chamber 1 through the gap and share the oil. When the horizontal piston column 6 moves vertically in the piston 4, one of the two first spaces is reduced, and the oil therein flows into the other enlarged first space through the gap between the horizontal piston column 6 and the side plate 3. Since the gap limits the flow speed of the oil, the speed-limiting flow of the oil can be used to achieve a buffering effect on the horizontal piston column 6 in the vertical direction. Of course, due to the horizontal The different pressures exerted on the piston 6 will result in different squeezing forces on the oil, which will result in different flow speeds of the oil through the gap. This can achieve an automatically adjustable buffering effect on different vibration pressures. When the horizontal piston 6 moves in the longitudinal direction, it will push the piston 4 to move longitudinally. At this time, one of the two second spaces is reduced, and the oil therein flows through the gap into the other enlarged second space. At this time, the speed-limiting flow of the oil through the gap can have a buffering effect on the horizontal piston 6 in the longitudinal direction. In this way, the structure in the buffer chamber 1 can have a buffering effect on the horizontal piston 6 in any direction on the vertical plane. The horizontal piston 6 transmits this buffering effect to the connecting arm 2, thereby having a buffering effect on any vibration direction of the engine in the vertical direction through the connecting arm 2.

[0021] It should be pointed out here that the sealing structure at the opening position of the buffer chamber 1 is mainly used to seal the oil to prevent the oil from flowing out of the opening position of the buffer chamber 1. The first spring 5 on the piston 4 and the second spring 7 on the horizontal plug 6 can provide elastic force for the horizontal plug 6 and help it to reset.

[0022] Compared with the traditional suspension structure, this solution can not only provide a buffering effect in the vertical direction, but also in the front and rear directions, which means that it can more effectively cope with the vibration of the engine in different directions and improve the overall stability and driving comfort of the vehicle; by using the movement of the piston 4 and the horizontal plug 6 to push the oil to flow through the gap, and then cooperating with the restriction of the gap on the oil flow rate, the different forces of the vibration pressure on the oil can be used to automatically adjust the flow rate of the oil in the gap, so as to achieve the automatic adjustment effect of the vibration buffering strength, which helps to maintain good buffering performance under various working conditions and adapt to a wider range of use environments; the structure is simple and compact, the processing of various components is convenient, the cost investment is low, and it is conducive to saving space, which is convenient for installation and layout in the limited space of modern cars; the solution uses the oil stored in the buffer chamber 1 to achieve buffering effects in multiple directions, reduce direct contact and wear between mechanical components, and thus improve the durability and reliability of the entire system.

[0023] Furthermore, the blocking structure includes a first baffle 8 and a second baffle 9 installed in the opening of the buffer chamber 1, a through opening is provided in the middle of the first baffle 8 and the middle of the second baffle 9, the first baffle 8 is located between the second baffle 9 and the side plate 3, a movable plate 10 is provided between the first baffle 8 and the second baffle 9, the horizontal plug 6 is fixed on the movable plate 10 through the through opening on the first baffle 8, and the connecting arm 2 is connected to the movable plate 10 through the through opening on the second baffle 9; The first baffle plate 8 and the second baffle plate 9 are used to limit the movable plate 10 , and a sealing structure is provided between the first baffle plate 8 and the movable plate 10 .

[0024] In detail, when the horizontal plug 6 moves, it will drive the movable plate 10 to slide between the first baffle 8 and the second baffle 9, and the movable plate 10 will drive the connecting arm 2 to move. The first baffle 8 and the second baffle 9 can limit the movable plate 10, so that the movable plate 10 can only move between the first baffle 8 and the second baffle 9. This can not only seal the opening of the buffer chamber 1, but also allow the movement of the horizontal plug 6 to be transmitted to the connecting arm 2.

[0025] It should be pointed out here that, since there is also a gap between the through opening on the first baffle 8 and the outer wall of the horizontal plug 6 , the oil can flow in the gap, which has little effect on the buffering effect of the horizontal plug 6 .

[0026] Furthermore, a plurality of balls 11 are rotatably provided on the end surface of the second baffle plate 9 facing the movable plate 10 , and the balls 11 are in contact with the side wall of the movable plate 10 .

[0027] In detail, by providing the balls 11, the friction between the movable plate 10 and the second baffle plate 9 can be reduced, thereby reducing wear.

[0028] Furthermore, the horizontal plug 6 is provided with an oil hole along its own length direction, and a plug post 12 is slidably arranged in the oil hole. The end of the plug post 12 away from the side plate 3 passes through the movable plate 10 and slides out. The plug post 12 is fixedly connected to the connecting arm 2, and the plug post 12 and the movable plate 10 are connected by a leaf spring 13.

[0029] In detail, the connecting arm 2 is connected to the movable plate 10 through the plug 12, and oil can be stored in the oil hole in the horizontal plug 6. When the plug 12 slides in the oil hole, the internal space of the oil hole changes, and the oil can enter and exit the oil hole through the gap between the horizontal plug 6 and the side plate 3. In this way, when the connecting arm 2 receives the vibration of the engine in the horizontal direction, the connecting arm 2 will push the plug 12 to slide in the oil hole in the horizontal plug 6, thereby allowing the oil to enter and exit the oil hole. The gap between the horizontal plug 6 and the side plate 3 also limits the inlet and outlet flow rate of the oil in the oil hole, thereby having a buffering effect on the engine in the horizontal direction. The leaf spring 13 can be used to provide a reset elastic force for the connecting arm 2 and the plug 12.

[0030] In actual use, since the movement of the plug 12 in the oil hole will cause the internal space of the buffer chamber 1 to increase or decrease, and the storage volume of the oil is fixed, in order to ensure the normal movement of the plug 12, an inert gas such as nitrogen can be filled on the upper side of the buffer chamber 1. When the plug 12 moves, the inert gas can be compressed or expanded. This method will not affect the buffering effect of the oil, and this method can also use gas compression and expansion to achieve a soft buffering effect, thereby protecting the engine.

[0031] Furthermore, the sealing structure includes a support frame 14 located inside the opening of the first baffle plate 8, a plurality of top columns 15 are arranged on the inner wall of the opening of the first baffle plate 8, and the support frame 14 is fixed on the top columns 15 by connecting bolts 16; An installation channel is formed between the outer wall of the top column 15 and the inner wall of the opening of the first baffle plate 8, and a sealing ring 17 and a sealing ring 18 are arranged in the installation channel. One side wall of the sealing ring 17 contacts the side wall of the movable plate 10, and the other side wall of the sealing ring 17 contacts the sealing ring 18. The cross-sectional shape of the end face of the sealing ring 18 facing the side plate 3 is a transverse herringbone. Among them, the cross-sectional shape of the sealing ring 17 is a horizontal T-shape, and a card groove used in conjunction with the shape of the sealing ring 17 is provided on the side of the outer wall of the support frame 14 close to the movable plate 10 and on the side of the inner wall of the opening of the first baffle plate 8 close to the movable plate 10, and a curved surface used in conjunction with the shape of the sealing ring 18 is provided on the side of the outer wall of the support frame 14 away from the movable plate 10 and on the side of the inner wall of the opening of the first baffle plate 8 away from the movable plate 10.

[0032] In detail, the support frame 14 is fixed to the first baffle 8 by a top column 15 and a connecting bolt 16. The support frame 14 is mainly used to form a mounting channel with the first baffle 8, and the mounting channel is used to install a sealing ring 17 and a sealing ring 18. The mounting channel is annular in shape. The oil in the buffer chamber 1 can enter the mounting channel and squeeze the sealing ring 17 through the sealing ring 18, thereby making the sealing ring 17 fit tightly with the movable plate 10, thereby improving the sealing effect of the sealing ring 17 on the movable plate 10.

[0033] Due to the shape characteristics of the sealing ring 18, when the oil acts on the two herringbone branches of the sealing ring 18, the herringbone branches of the sealing ring 18 will be tightly attached to the arc surface of the outer wall of the support frame 14 or the arc surface of the inner wall of the opening of the first baffle 8, thereby improving the sealing performance of the sealing ring 18 to the installation channel.

[0034] The sealing ring 17 is a low-friction ring made of materials such as polytetrafluoroethylene. By adopting this structure, a sealing effect can be achieved while reducing friction.

[0035] Furthermore, a slot is provided on a side of the arc surface of the outer wall of the support frame 14 away from the movable plate 10 and a side of the arc surface of the inner wall of the opening of the first baffle plate 8 away from the movable plate 10 .

[0036] In detail, the outer ends of the two herringbone branches of the sealing ring 18 are set as hidden ends 19, and the two hidden ends 19 are respectively inserted into two slots. In this way, the position of the sealing ring 18 can be limited by the two slots, and the hidden ends 19 can be conveniently hidden, so that the oil directly acts on the herringbone arc surface of the sealing ring 18.

[0037] Furthermore, two deformation holes 20 are defined in the sealing ring 18 .

[0038] In detail, the two deformation holes 20 are respectively located on the two herringbone branches of the sealing ring 18, so that when the oil squeezes the herringbone branches, they can be deformed and the herringbone branches can be extended toward the slot direction to make the hidden end 19 fit more closely with the slot.

[0039] Further, the side plate 3 slides in the buffer chamber 1, and the sliding direction of the side plate 3 is along a direction perpendicular to the surface where the side plate 3 is located. The side plate 3 divides the inside of the buffer chamber 1 into two third chambers on the left and right. A notch is opened on the side plate 3, and the two third chambers are connected through the notch. A threaded sleeve 21 is fixed on the side wall of the side plate 3 away from the piston 4. The threaded sleeve 21 slides through the buffer chamber 1 and extends out. A threaded rod 23 is screwed in the threaded sleeve 21. The buffer chamber 1 is provided with an adjustment motor 22 for providing power to the threaded rod 23; The piston 4 , the first spring 5 , the horizontal plug 6 and the second spring 7 are all located in the third chamber on one side of the side plate 3 .

[0040] In detail, since the position of the side plate 3 in the buffer chamber 1 is adjustable, the size of the gap between the piston 4 and the side plate 3 is adjustable, so that the buffering strength of the oil can be adjusted. The adjusting motor 22 can push the threaded sleeve 21 to move through the threaded rod 23, thereby driving the side plate 3 to move, and the oil in the two third chambers can flow through the notch on the side plate 3.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
