Description

Technical Field

[0002] As a key auxiliary tool, the racing car lift is widely used in the Formula Student car competition. Its design and performance directly affect the maintenance efficiency and performance of the car. The China Formula Student car competition requires that the four-wheel lift can lift the vehicle by a single person so that all driving wheels are at least 100mm off the ground and the vehicle is fully supported. Although the existing racing car lift meets the basic lifting needs, it has some obvious limitations in practical applications. First, due to the unreasonable design of its lever, it requires a lot of force when operated by a single person, which not only increases the difficulty of operation, but also may cause physical burden on the operator; secondly, the stability and self-locking ability after lifting are insufficient, which is particularly critical in the rapidly changing competition environment, because any unstable factors may cause delays in the maintenance of the car or accidents. In addition, the existing lift is relatively wasteful in the use of materials, which increases the manufacturing cost, which is particularly unfavorable in the cost-sensitive competition environment, especially in the cost defense link, which is not conducive to demonstrating the economy and environmental awareness of the racing team.

[0028] like Figure 1As shown, the utility model provides a formula car lifter, which includes: a rotating shaft 110, the outer surface of which is provided with threads; two smooth hole shafts 120, the middle position of which is radially provided with a smooth through hole 121; two threaded shafts 130, the middle position of which is radially provided with a threaded through hole; wherein, the rotating shaft 110 passes through the smooth through hole 121 to connect with the smooth hole shaft 120, and retaining rings 122 are arranged on both sides of the connection between the smooth hole shaft 120 and the rotating shaft 110, so that the smooth hole shaft 120 is fixedly connected with the rotating shaft 110 and cannot move relative to the rotating shaft 110; the rotating shaft 110 passes through the threaded through hole and is connected with the threaded shaft 130 by threads; the smooth hole shaft 120 and the threaded shaft 130 are arranged at intervals; four upper seats 140, four bases 150, each of which has two through holes inside; the upper seat 140 and the base 150 are arranged at the four corners of the lifter in a one-to-one correspondence; eight upper arms 160, one end of which is hinged to the upper seat 140; each of the upper seat 140 and the two upper arms 160 are correspondingly connected through a pin shaft 180; eight lower arms 170, one end of which is hinged to the base 150; each of the base 150 and the two lower arms 170 are correspondingly connected through the pin shaft 180; one end of the pin shaft 180 is provided with a pin cap with a diameter larger than the diameter of the pin shaft 180, and a pin hole 181 is radially arranged near the other end. When the upper seat 140 is hinged to the upper arm 160 and the base 150 is hinged to the lower arm 170, , the pin shaft 180 passes through the through holes of the upper seat 140 and the base 150, so that the upper seat 140 and the upper arm 160, the base 150 and the lower arm 170 are fixedly connected, and the pin shaft rod is inserted into the pin holes 181 of the two pin shafts 180 of the upper seat 140 or the base 150 at the same time to enhance the stability of the lifter; wherein, the other end of the upper arm 160 is hinged with the other end of the lower arm 170, and is connected with the light hole shaft 120 or the threaded shaft 130; the upper arm 160 and the lower arm 170, the upper arm 160 or the lower arm 170 and the threaded shaft 130 or the light hole shaft 120 are all connected one by one; the rotating handle 210, which is connected to the rotating shaft 110 through the The universal joint 220 can be detachably connected, and the universal joint 220 can be a cross-axis universal joint or a ball universal joint, which can improve the lifting efficiency and make it easier for a single person to operate the lifter; the rotating handle 210 has a certain angle with the rotating shaft 110, so that the rotating handle 210 is also convenient to rotate when the lifter is just started; the reinforcing frame 230 is composed of a plurality of reinforcing ribs 231; the bases 150 are connected to each other by a reinforcing rib 231; the triangular support 240 is arranged on the outside of the two reinforcing ribs 231 parallel to the rotating shaft 110 to prevent the lifter from tipping over due to the rotation of the rotating shaft 110 and prevent the lifter from sliding relative to the ground; the platform plate 250 is rectangular in shape;The platform plate 250 is arranged above the upper seat 140, and the four corners of the platform plate 250 are fixedly connected to the upper seat 140, so that the contact surface between the lifter and the racing car is increased, thereby ensuring the stability of the racing car during the lifting process.

[0029] When the racing car needs to be lifted, the rotating handle 210 is turned to make the universal joint 220 drive the rotating shaft 110 to rotate. When the racing car is on the lifter, under the action of gravity, the threaded shaft 130 will not move axially or along the axial direction of the rotating shaft 110, which is equivalent to the threaded shaft 130 being fixed, and the rotating shaft 110 moving forward and backward along the axial direction of the rotating shaft 110 relative to the threaded shaft 130. Since the retaining rings 122 are arranged on both sides of the connection between the light hole shaft 120 and the rotating shaft 110, the light hole shaft 120 is fixedly connected to the rotating shaft 110, and the light hole shaft 120 moves axially along the rotating shaft 110 together with the rotating shaft 110, thereby driving the upper arm 160 and the lower arm 170 to rotate, and the angle between the upper arm 160 and the lower arm 170 after connection gradually increases, so that the upper seat 140 is raised, so that the lifter can lift the racing car; when the racing car is lifted to the highest point by the lifter, it stops rotating, and the threaded structure of the rotating shaft 110 and the threaded shaft 130 can achieve self-locking, so that the lifter is fixed at the lifted height.

[0030] like Figure 2 As shown, the smooth through hole 121 is radially arranged in the middle position of the light hole axis 120, and the diameters of the two end heads of the light hole axis 120 are smaller than the diameters of the through holes of the ends of the upper arm 160 and the lower arm 170, so that after the upper arm 160 and the lower arm 170 are hinged, the ends of the light hole axis 120 can pass through the through holes of the ends of the upper arm 160 and the lower arm 170 to connect the upper arm 160 and the lower arm 170 together; a thread is axially arranged on the inner wall of the end head of the light hole axis 120, and a limiting bolt 190 is arranged on the outer side after the upper arm 160 and the lower arm 170 are hinged, so that the upper arm 160 and the lower arm 170 are connected to the light hole axis 120, and at the same time play a limiting role to prevent the upper arm 160 and the lower arm 170 from moving axially along the light hole axis 120 after being hinged.

[0031] The shape of the threaded shaft 130 and the connection method with the upper arm 160 and the lower arm 170 are consistent. The difference is that the threaded through hole is radially arranged in the middle position of the threaded shaft 130, and the outer surface of the rotating shaft 110 is provided with threads at a certain distance at the position connected to the threaded shaft 130, so that the rotating shaft 110 and the threaded shaft 130 are connected by threads.

[0032] The diameter of the smooth hole shaft 120 or the threaded shaft 130 is thickened at the connection with the rotating shaft 110; the outer surface of the rotating shaft 110 is only provided with threads at a certain distance, and the outer surface at other positions can be a smooth surface, which can not only meet the lifting distance of the lifter, but also reduce costs.

[0033] like Figure 3 As shown, after the light hole axis 120 is connected to the rotating shaft 110, the retaining rings 122 are arranged on both sides of the light hole axis 120 to fix the light hole axis 120 on the rotating shaft 110, so that the light hole axis 120 can move axially along the rotating shaft 110 together with the rotating shaft 110.

[0034] The threaded shaft 130 is connected to the rotating shaft 110 by threads, and the retaining rings 122 are not provided on both sides; when the racing car is located on the lifter, under the action of gravity, the threaded shaft 130 will not move axially or along the axial direction of the rotating shaft 110, which is equivalent to the threaded shaft 130 being fixed, and the rotating shaft 110 moves forward and backward along the axial direction of the rotating shaft 110 relative to the threaded shaft 130.

[0035] like Figure 4 As shown, the support mechanism 310 is composed of the upper seat 140, the base 150, the upper arm 160, and the lower arm 170; the upper arm 160 is divided into a first upper arm 161 and a second upper arm 162; the lower arm 170 is divided into a first lower arm 171 and a second lower arm 172; the upper seat 140 is hinged with one end of the first upper arm 161 and the second upper arm 162, the pin shaft 180 passes through the two through holes of the upper seat 140 from one side of the upper seat 140, and the pin shaft rod is inserted into the pin holes 181 of the two pin shafts 180 on one side of the upper seat 140, so that the upper seat 140 and the first upper arm 161 are hinged. 1 and one end of the second upper arm 162 are stably connected; the base 150 is hinged to one end of the first lower arm 171 and the second lower arm 172, the pin shaft 180 passes through the two through holes of the base 150 from one side of the base 150, and the pin shaft rod is inserted into the pin holes 181 of the two pin shafts 180 on one side of the base 150, so that the base 150 is stably connected to one end of the first lower arm 171 and the second lower arm 172; the other end of the first upper arm 161 is hinged to the other end of the first lower arm 171, and the other end of the second upper arm 162 is hinged to the other end of the second lower arm 172.

[0036] like Figure 5As shown, the lifting mechanism 320 is composed of two supporting mechanisms 310 connected with the threaded shaft 130 and the light hole shaft 120; the other end of the first upper arm 161 is hinged to the other end of the first lower arm 171, and one end of the light hole shaft 120 passes through the through holes of the first upper arm 161 and the first lower arm 171, and the outer side is connected to the light hole shaft 120 through the limiting bolt 190, so that the other ends of the first upper arm 161 and the first lower arm 171 are connected to the light hole shaft 120 together, and at the same time play a limiting role to prevent the other end of the first upper arm 164 from moving axially along the light hole shaft 120 after being hinged to the other end of the first lower arm 171.

[0037] The other end of the second upper arm 162 is hinged to the other end of the second lower arm 172, and one end of the threaded shaft 130 passes through the through holes in the second upper arm 162 and the second lower arm 172, and the outer side is connected to the threaded shaft 130 through the limiting bolt 190, so that the other ends of the second upper arm 162 and the second lower arm 172 are connected to the threaded shaft 130 together, and at the same time play a limiting role to prevent the other end of the second upper arm 162 from moving axially along the threaded shaft 130 after being hinged to the other end of the second lower arm 172.

[0038] The two supporting mechanisms 310 are arranged at both ends of the light hole shaft 120 and the threaded shaft 130 and connected to form the lifting mechanism 320; the two lifting mechanisms 320 are arranged at different positions of the rotating shaft 110, one lifting mechanism 320 is arranged at the end of the rotating shaft 110, and the other is arranged near the position where the rotating shaft 110 is connected to the rotating handle 210, thereby forming a complete racing car lift.

[0039] A handle through hole can be additionally provided at the end of the rotating handle 210, and a round tube can be inserted into the handle through hole, so that single-person operation is simpler and more labor-saving; the rotating shaft 110 and the rotating handle 210 can be connected without using the universal joint 220. A rotating shaft through hole 111 is radially provided at the end where the rotating shaft 110 and the rotating handle 210 are connected, and a round tube can be directly inserted into the rotating shaft through hole 111. By rotating the round tube to apply a lateral force, the rotating shaft 110 is driven to rotate, thereby lifting the racing car; a detachable handle can also be directly used at the end of the rotating shaft 110, and the lifting of the racing car can also be achieved by rotating the handle.

[0040] The lifter does not need to use the platform plate 250 to lift the racing car, and the four upper seats 140 can be directly used to lift the vehicle. It only needs to increase the surface roughness of the upper seats 140 during processing to increase the friction force; or the four upper seats 140 are connected by a cross bar to avoid relative sliding between the racing car and the lifter during the lifting process of the racing car.

[0041] The threaded through hole and the threads outside the rotating shaft 110 can be processed into double-thread threads, which can not only improve the lifting efficiency, but also improve the self-locking stability of the lifter.

[0042] In order to reduce the cost, the lifter may not use the reinforcing frame 230, a small triangular support may be provided on the outside of the base 150, and the surface roughness of the base 150 may be increased, which may also meet the strength requirements of the racing car.

[0043] The formula car lift provided by the utility model has a simple structure, can improve the convenience of single-person operation, and enhance the stability and self-locking ability after lifting; multiple single lifting points similar to jacks are connected together, which reduces the manufacturing cost, is simple to process, and is easier to carry and more labor-saving than existing lifts. The formula car lift provided by the utility model adopts a combination of a threaded shaft and a light hole shaft, combined with the principle of self-locking thread and lever, which significantly improves the convenience of single-person operation, and enhances the stability and self-locking ability after lifting. In addition, the lift is more economical and reasonable in the use of materials, reduces the manufacturing cost, and maintains sufficient strength and stability, which meets the needs of cost-sensitive and environmentally conscious stadiums; the overall design is compact and easy to carry, providing an efficient and safe solution for formula car maintenance.
