Description

Technical Field

[0001] The invention relates to the technical field of automobile shock-absorbing chassis, and in particular to a shock-absorbing chassis for a new energy automobile. Background Art

[0002] With the increasing development of new energy vehicles and the continuous progress of science and technology, the technical requirements for key components related to the technical level of new energy vehicles are becoming higher and higher. The chassis of existing new energy vehicles are also constantly being updated to meet the development of new energy vehicles, but there are still some problems with the chassis of existing new energy vehicles.

[0003] The Chinese patent with publication number CN114771658A discloses a shock-absorbing chassis for new energy vehicles, which relates to the automotive field. The chassis includes an I-shaped base, and mounting frames are fixedly installed at the four corners of the top of the I-shaped base, and the number of mounting frames is four. A moving ring is slidably connected in the mounting frame, and the same axle is rotatably connected through two moving rings on the same side, and the front and rear ends of the axle extend to the front and rear sides of the I-shaped base respectively and are connected to wheel hubs. A connecting cover is fixedly installed on the top of the mounting frame, and a pressure rod is slidably connected in the connecting cover, and the bottom end of the pressure rod extends into the mounting frame and is fixedly connected to the top of the moving ring. After being assembled on the automobile, the present invention can provide stable buffering protection for the automobile, thereby ensuring that the I-shaped base has stable support and stability when actually used, so it has good practicality.

[0004] However, the above patent has the following shortcomings:

[0005] 1. The above patent can provide space for sliding displacement when the axle undergoes longitudinal vibration through the sliding connection between the moving ring and the mounting frame, which is convenient for shock absorption and buffering. However, the moving ring and the mounting frame will cause wear during long-term use, which will cause the diameter of the moving ring to continue to increase, resulting in an excessively large gap between the moving ring and the mounting frame, which will cause instability when the moving ring slides on the mounting frame.

[0006] 2. The above patent reduces shock by the action of a buffer spring. During long-term use of the buffer spring, its length will become shorter, and thus the distance between the parts cooperating with the buffer spring and the buffer spring needs to be adjusted so that the parts cooperating with the buffer spring are always in a cooperating state with the buffer spring. Summary of the invention

[0007] The purpose of the present invention is to provide a shock-absorbing chassis for a new energy vehicle to solve the problem of being unable to adsorb and clean metals proposed in the above-mentioned background technology.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a shock-absorbing chassis for a new energy vehicle, comprising a vehicle bottom, a rectangular frame is horizontally arranged on the top of the vehicle bottom, and a mounting plate is vertically installed on the top of the rectangular frame, rectangular rods are horizontally installed on both side walls of the mounting plate, cylinders are horizontally installed on the sides of the two rectangular rods away from each other, and the ends of the two cylinders away from each other are installed to the inner wall of the rectangular frame, threads are opened on the ends of the cylinders away from each other, a rectangular sleeve is sleeved on the rectangular rod, and a sliding component is arranged in the rectangular sleeve, an adjustment component is arranged on the end of the cylinder with the threaded wire, and a support shock-absorbing component is vertically arranged on the bottom of the rectangular frame;

[0009] The sliding assembly includes a first rotating roller and a second rotating roller. The second rotating roller is installed at the top and bottom of the rectangular sleeve for transverse rotation. The first rotating roller is installed at both sides of the rectangular sleeve for vertical rotation. A rectangular rod is inserted between the first rotating roller and the second rotating roller.

[0010] As a further solution of the present invention: the adjustment component includes a threaded sleeve and an annular plate, the end of the cylinder away from each other is sleeved with a threaded sleeve, and the threaded sleeve is threadedly connected to the cylinder, and the outer side of the cylinder is respectively slidably sleeved with an annular plate and a first spring.

[0011] By adopting the above technical solution, when the first spring becomes shorter during long-term use, the threaded sleeve is rotated to approach the first spring, thereby pushing the annular plate to contact the first spring to adapt to the gap between the first spring and the threaded sleeve after the first spring becomes shorter.

[0012] As a further solution of the present invention: a plurality of fixing grooves are provided on the outer side of the cylinder, and fixing bolts are threadedly penetrated through the outer side of the threaded sleeve, and the penetrating ends of the fixing bolts are inserted into the fixing grooves.

[0013] By adopting the above technical solution, it is achieved that the thread is inserted and fixed on the cylinder after the thread is rotated.

[0014] As a further solution of the present invention: a rotating handle is vertically installed on the outer side of the threaded sleeve, and a ball is installed on one end of the rotating handle away from the threaded sleeve.

[0015] By adopting the above technical solution, the threaded sleeve is driven to rotate on the cylinder by pushing the rotating handle.

[0016] As a further solution of the present invention: a circular cylinder is transversely installed on the side of each rectangular sleeve away from each other, and each circular cylinder is slidably sleeved on the outside of the cylinder, and the side of the circular cylinder away from each other is in contact with the side wall of the first spring.

[0017] By adopting the above technical solution, it is realized that the rectangular sleeve is moved on the rectangular rod to move on the track, thereby pushing the circular tube to squeeze the first spring, thereby playing a shock-absorbing role.

[0018] As a further solution of the present invention: a connecting rod is rotatably mounted on the bottom of each rectangular sleeve, and one end of the connecting rod away from the rectangular frame is rotatably mounted to the top of the bottom of the car.

[0019] By adopting the above technical solution, the force on the rectangular frame is buffered.

[0020] As a further solution of the present invention: the support shock absorbing assembly includes a guide cylinder, a circular column and a second spring, the guide cylinders are vertically installed on both sides of the top of the bottom of the car, and the circular columns are slidably inserted into the top of the guide cylinders, the tops of the circular columns are connected to the top of the rectangular frame, and the second spring is vertically sleeved on the outside of the circular column and the guide cylinder.

[0021] By adopting the above technical solution, the effect of shock absorption on the bottoms of both ends of the rectangular frame is achieved.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the shock-absorbing chassis of the new energy vehicle,

[0023] A first rotating roller and a second rotating roller are provided. When the bottom of the car is compressed upward by pressure, the connecting rod is pushed upward by the bottom of the car. At this time, the top of the connecting rod pushes the rectangular sleeve to move laterally on the outside of the rectangular rod. When the rectangular sleeve moves laterally, the second rotating roller rotatably installed on the top and bottom of the rectangular sleeve rotates on the top and bottom of the rectangular rod. At the same time, the first rotating roller rotatably installed on the side wall of the rectangular sleeve rotates on the outer side wall of the rectangular rod, thereby reducing the friction between the laterally moving rectangular sleeve and the rectangular rod, thereby preventing the rectangular sleeve from being worn during long-term use.

[0024] In addition, the shock-absorbing chassis of the new energy vehicle is also provided with a threaded sleeve and an annular plate. When the distance between the shortened first spring and the threaded sleeve needs to be reduced, the threaded sleeve on the cylinder is rotated to approach the first spring. During the process of the threaded sleeve approaching the first spring, the annular plate is pushed to approach the first spring, thereby pushing the annular plate to contact the first spring, thereby solving the problem of the first spring moving back and forth laterally on the cylinder due to the first spring becoming shorter during long-term use.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-5 The present invention provides a technical solution: a shock-absorbing chassis for a new energy vehicle, comprising a vehicle bottom 1, a rectangular frame 2 is horizontally arranged on the top of the vehicle bottom 1, and a mounting plate 19 is vertically installed on the top of the rectangular frame 2, rectangular rods 3 are horizontally installed on both side walls of the mounting plate 19, cylinders 7 are horizontally installed on the sides of the two rectangular rods 3 away from each other, and the ends of the two cylinders 7 away from each other are installed to the inner wall of the rectangular frame 2, and the ends of the cylinders 7 away from each other are provided with threaded wires 12, a rectangular sleeve 4 is sleeved on the rectangular rod 3, and a sliding component is arranged in the rectangular sleeve 4, an adjustment component is arranged on the end of the cylinder 7 with the threaded wire 12, and a supporting shock-absorbing component is vertically arranged at the bottom of the rectangular frame 2;

[0033] The sliding assembly includes a first rotating roller 13 and a second rotating roller 14. The second rotating roller 14 is installed in a horizontal rotation at the top and bottom of the rectangular sleeve 4. The first rotating roller 13 is installed in a vertical rotation at both sides of the rectangular sleeve 4. A rectangular rod 3 is inserted between the first rotating roller 13 and the second rotating roller 14.

[0034] When the bottom 1 of the automobile is compressed upward by pressure, the connecting rod 15 is pushed upward by the bottom 1 of the automobile, and the top of the connecting rod 15 pushes the rectangular sleeve 4 to move laterally on the outside of the rectangular rod 3. When the rectangular sleeve 4 moves laterally, the second rotating roller 14 rotatably installed at the top and bottom of the rectangular sleeve 4 rotates at the top and bottom of the rectangular rod 3, and at the same time, the first rotating roller 13 rotatably installed on the side wall of the rectangular sleeve 4 rotates on the outer side wall of the rectangular rod 3, thereby reducing the friction between the laterally moving rectangular sleeve 4 and the rectangular rod 3, preventing the rectangular sleeve 4 from wearing out during long-term use.

[0035] See also Figure 1 and Figure 5 , further, the adjustment component includes a threaded sleeve 8 and an annular plate 20, the end of the cylinder 7 away from each other is sleeved with the threaded sleeve 8, and the threaded sleeve 8 is threadedly connected to the cylinder 7, and the outer side of the cylinder 7 is respectively slidably sleeved with the annular plate 20 and the first spring 6;

[0036] When the distance between the shortened first spring 6 and the threaded sleeve 8 needs to be reduced, the threaded sleeve 8 on the rotating cylinder 7 is moved closer to the first spring 6. During the process of the threaded sleeve 8 approaching the first spring 6, the annular plate 20 is pushed closer to the first spring 6, thereby pushing the annular plate 20 to contact the first spring 6, thereby solving the problem of the first spring 6 becoming shorter during long-term use, causing the first spring 6 to move back and forth laterally on the cylinder 7.

[0037] See also Figure 3 Furthermore, a plurality of fixing grooves 10 are provided on the outer side of the cylinder 7, and a fixing bolt 9 is threadedly penetrated through the outer side of the threaded sleeve 8, and the through end of the fixing bolt 9 is inserted into the fixing groove 10;

[0038] When the threaded sleeve 8 is rotated on the thread 12 opened on the cylinder 7, the fixing bolt 9 is rotated. When the fixing bolt 9 approaches the cylinder 7, the through end of the cylinder 7 is inserted into the fixing groove 10, thereby fixing the adjusted threaded sleeve 8 to prevent the threaded sleeve 8 from loosening during use.

[0039] See also Figure 3 Furthermore, a rotating handle 11 is vertically installed on the outer side of the threaded sleeve 8, and a ball is installed at one end of the rotating handle 11 away from the threaded sleeve 8;

[0040] When the threaded sleeve 8 needs to be rotated, the threaded sleeve 8 is driven to rotate by pushing the rotating handle 11 installed on the threaded sleeve 8, thereby making the threaded sleeve 8 approach the first spring 6 during the rotation process, so that the pushing personnel can push the threaded sleeve 8 to rotate more easily.

[0041] See also Figure 4 , further, a circular cylinder 5 is transversely installed on the side away from each other of each rectangular sleeve 4, and each circular cylinder 5 is slidably sleeved on the outside of the cylinder 7, and the side away from each other of the circular cylinder 5 is in contact with the side wall of the first spring 6;

[0042] When the rectangular sleeve 4 slides on the rectangular rod 3, the circular tube 5 installed on the rectangular sleeve 4 moves laterally outside the cylindrical body 7. When the circular tube 5 moves laterally, it pushes the first spring 6 to contract. When the first spring 6 contracts, it achieves shock absorption of the force transmitted to the bottom 1 of the car.

[0043] See also Figure 1 , further, a connecting rod 15 is rotatably mounted on the bottom of each rectangular sleeve 4, and one end of the connecting rod 15 away from the rectangular frame 2 is rotatably mounted to the top of the bottom 1 of the car;

[0044] When the automobile bottom 1 is subjected to force, the two connecting rods 15 rotatably installed on the top of the automobile bottom 1 are rotatably installed to the bottom of the rectangular sleeve 4, thereby transmitting the force transmitted from the automobile bottom 1 to the rectangular sleeve 4, and then moving laterally through the two rectangular sleeves 4, thereby achieving a shock-absorbing effect on the automobile bottom 1.

[0045] See also Figure 1 , further, the support shock absorption assembly includes a guide cylinder 16, a circular column 17 and a second spring 18, the guide cylinders 16 are vertically installed on both sides of the top of the car bottom 1, and the top of the guide cylinder 16 is slidably inserted with a circular column 17, the top of the circular column 17 is connected to the top of the rectangular frame 2, and the second spring 18 is vertically sleeved on the outer side of the circular column 17 and the guide cylinder 16;

[0046] When the automobile bottom 1 is subjected to impact force, the circular column 17 sliding sleeve installed vertically at the lower part of the rectangular frame 2 is inserted into the guide cylinder 16 installed vertically at the top of the automobile bottom 1, so as to guide the rectangular frame 2 moving up and down. When the automobile bottom 1 and the rectangular frame 2 are close to each other, the second spring 18 installed between the rectangular frame 2 and the automobile bottom 1 realizes the shock absorption effect on the automobile bottom 1.

[0047] Working principle: When the shock-absorbing chassis of new energy vehicles is used, when the bottom 1 of the vehicle is compressed upward by pressure, the connecting rod 15 is pushed upward by the bottom 1 of the vehicle, and the top of the connecting rod 15 at this time pushes the rectangular sleeve 4 to move laterally on the outside of the rectangular rod 3. When the rectangular sleeve 4 moves laterally, the second rotating roller 14 rotatably installed at the top and bottom of the rectangular sleeve 4 rotates at the top and bottom of the rectangular rod 3, and at the same time, the first rotating roller 13 rotatably installed on the side wall of the rectangular sleeve 4 rotates on the outer side wall of the rectangular rod 3, and the circular cylinder 5 installed on the rectangular sleeve 4 moves laterally on the outside of the cylinder 7. When the circular cylinder When the first spring 6 is contracted, the force transmitted to the bottom 1 of the vehicle is reduced. At the same time, the circular column 17 installed vertically at the lower part of the rectangular frame 2 is inserted into the guide cylinder 16 installed vertically at the top of the bottom 1 of the vehicle to guide the rectangular frame 2 moving up and down. When the bottom 1 of the vehicle and the rectangular frame 2 are close to each other, the second spring 18 installed between the rectangular frame 2 and the bottom 1 of the vehicle is further reduced.
