Description

Technical Field

[0001] The invention relates to the technical field of shock absorbers, and in particular to a double shock absorber for a sightseeing vehicle. Background Art

[0002] The shock absorbers in some existing electric sightseeing vehicles use spring shock absorbers, which have a relatively simple structure and poor shock absorption effect. It is not easy to ensure the stability of the sightseeing vehicle during driving. After long-term use, the spring of this single-structure spring shock absorber is prone to deformation; when driving on a bumpy road, the spring rebounds slowly, which reduces the stability of the sightseeing vehicle and affects the service life of the shock absorber of the sightseeing vehicle. Summary of the invention

[0003] In view of the above-mentioned technical deficiencies, the technical problem to be solved by the present invention is to provide a double shock absorber for a sightseeing vehicle which can reduce the bumpy feeling during driving and improve the stability.

[0004] In order to solve the above technical problems, the present invention provides a double shock absorber for a sightseeing vehicle, comprising:

[0005] Mounting seat;

[0006] A shock-absorbing cylinder assembly, which is movably arranged on the top surface of the mounting seat;

[0007] A connecting seat, which is arranged at one end of the shock absorbing cylinder assembly away from the mounting seat;

[0008] A shock absorber assembly, wherein two shock absorber assemblies are provided, and the two shock absorber assemblies are respectively connected obliquely to two opposite ends of the connecting seat, and one end of the shock absorber assembly away from the connecting seat is connected to the mounting seat;

[0009] The shock-absorbing cylinder assembly includes a shock-absorbing rod vertically arranged on a mounting seat, an outer cylinder coaxial with the shock-absorbing rod is arranged on the connecting seat, one end of the shock-absorbing rod away from the mounting seat is movable and penetrates into the outer cylinder, a pressure plate is rotatably arranged on the outer side of one end of the shock-absorbing rod close to the mounting seat, a shock-absorbing spring is arranged on the outside of the outer cylinder, and the outer diameter of the shock-absorbing spring is smaller than the diameter of the pressure plate;

[0010] The shock absorber assembly includes a main shock absorber, one end of the main shock absorber away from the mounting seat is movably connected to the connecting seat through an adjusting slot, the other end of the main shock absorber away from the connecting seat is connected to the mounting seat, and an auxiliary shock absorber is arranged parallel to the outside of the main shock absorber.

The position of the pressure plate can be adjusted by rotating on the externally threaded rod to achieve different buffering effects for the sightseeing vehicle.

[0012] Preferably, the main shock absorber is a hydraulic shock absorber, the piston rod of the main shock absorber is hinged to the mounting seat, a sliding shaft is rotatably arranged on the cylinder of the main shock absorber, an adjusting slide groove is arranged on the connecting seat, and the sliding shaft is movably arranged through the connecting seat.

Two buffer plates are symmetrically arranged in the waist-shaped through hole, and the sliding shaft is located between the two buffer plates. The outer peripheral wall of the sliding shaft is in conflict with the buffer plate. When the sightseeing car is bumpy when driving on a complex road, the sliding shaft can move in the waist-shaped through hole and conflict with the buffer plate at the same time, causing the buffer plate to deform, thereby playing a buffering role.

[0017] A buffer steel plate, wherein both ends of the arc-shaped opening of the buffer steel plate are respectively connected to the upper plate and the lower plate, and the arc-shaped top of the buffer steel plate is located at the end close to the sliding shaft, and the outer peripheral wall of the sliding shaft conflicts with the arc-shaped top of the buffer steel plate. When the sightseeing car encounters bumps when driving on a complex road, the sliding shaft can move in the waist-shaped through hole and conflict with the arc-shaped top of the buffer steel plate, causing the buffer steel plate to deform, thereby playing a buffering role.

[0018] Preferably, the arc-shaped top of the buffer steel plate has a plurality of anti-slip protrusions evenly distributed along the circumferential direction, which can prevent or reduce the sliding of the sliding shaft when it conflicts with the arc-shaped top of the buffer steel plate.

[0022] An outer sleeve, an inner wall of which is provided with two internal threads, an outer portion of the piston rod of the auxiliary shock absorber body is provided with an external thread, the outer sleeve is threadedly connected to the outside of the piston rod of the auxiliary shock absorber body, and one end of the outer sleeve away from the piston rod of the auxiliary shock absorber body corresponds to the position of the trigger rod, the auxiliary shock absorber body and the outer sleeve are coaxial, when the sightseeing car is driving on a complex road and the bumps are more serious, the outer sleeve can conflict with the trigger rod, thereby facilitating the auxiliary shock absorber body to play a buffering role, thereby improving the shock absorbing effect on the sightseeing car.

[0023] Preferably, the mounting seat is also rotatably provided with limit wheels at both opposite ends, and the limit wheels can provide a certain degree of protection for the mounting seat to prevent the mounting seat from colliding with obstacles on the road surface when the sightseeing vehicle is traveling on a complex road surface, thereby causing damage to the shock absorber cylinder assembly and the shock absorber assembly.

[0024] The beneficial effects of the present invention are as follows: a double shock-absorbing structure is formed between the main shock absorber and the auxiliary shock absorber arranged in parallel in the present invention, which can reduce the bumpy feeling when the sightseeing car is traveling on a bumpy road surface and improve the shock-absorbing effect; the arrangement of the shock-absorbing cylinder assembly can supplement the shock-absorbing effect of the main shock absorber when in use, and can avoid the disadvantage that the shock-absorbing effect is affected by the slow rebound of the shock absorber assembly when bumping; the limiting wheel can play a certain protective role on the mounting seat. When an obstacle appears on the road surface, the limiting wheel can conflict with the obstacle when the sightseeing car is traveling, thereby avoiding the mounting seat from colliding with the obstacle on the road surface, which is easy to cause damage to the shock-absorbing cylinder assembly and the shock absorber assembly, thereby ensuring the stability and safety of the sightseeing car.

[0032] 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.

[0033] Embodiment 1

[0034] like Figures 1 to 5As shown, the present invention provides a double shock absorber for a sightseeing car, comprising a mounting seat 1; a shock absorber cylinder assembly 2 is movably arranged on the top surface of the mounting seat 1; a connecting seat 3 is arranged at one end of the shock absorber cylinder assembly 2 away from the mounting seat 1; two shock absorber assemblies 4 are arranged, and the two shock absorber assemblies 4 are respectively obliquely connected to the two opposite ends of the connecting seat 3, and the end of the shock absorber assembly 4 away from the connecting seat 3 is connected to the mounting seat 1; the shock absorber cylinder assembly 2 comprises a shock absorber rod 21 vertically arranged on the mounting seat 1, an outer cylinder 22 coaxial with the shock absorber rod 21 is arranged on the connecting seat 3, the end of the shock absorber rod 21 away from the mounting seat 1 is movably penetrated into the outer cylinder 22, a pressure plate 23 is rotatably arranged on the outer side of the shock absorber rod 21 close to one end of the mounting seat 1, a shock absorber spring 24 is arranged on the outside of the outer cylinder 22, and the outer diameter of the shock absorber spring 24 is smaller than the diameter of the pressure plate 23; the shock absorber assembly 4 comprises a main shock absorber 41, one end of the main shock absorber 41 away from the mounting seat 1 is movably connected to the connecting seat 3 through an adjusting slot 42, and the one end of the main shock absorber 41 away from the connecting seat 3 is connected to the mounting seat 1, and an auxiliary shock absorber 43 is arranged in parallel on the outside of the main shock absorber 41; an external threaded rod 25 is coaxially arranged on the outside of the end of the shock absorber rod 21 close to the mounting seat 1, the pressure plate 23 is a circular ring structure, and an internal thread one matched with the external threaded rod 25 is arranged on the inner circumferential wall of the pressure plate 23, the pressure plate 23 is threadedly connected to the outside of the external threaded rod 25, and a locking nut 26 that conflicts with the pressure plate 23 is also threadedly connected to the external threaded rod 25; the main shock absorber 41 is a hydraulic shock absorber, the piston rod of the main shock absorber 41 is hinged to the mounting seat 1, a sliding shaft 44 is rotatably arranged on the cylinder barrel of the main shock absorber 41, the adjusting slot 42 is arranged on the connecting seat 3, and the sliding shaft 44 is movably arranged through the connecting seat 3.

[0035] First, connect the connecting seat 3 to the chassis of the sightseeing car, and install the wheel on the side wall of the mounting seat 1 (and make the wheel installed at the position between the two shock absorber assemblies 4). When the sightseeing car is bumpy when driving on the road, the wheel and the mounting seat 1 can drive the shock absorber rod 21 to move back and forth in the outer cylinder 22. When the pressure plate 23 conflicts with the shock absorber spring 24, the shock absorber spring 24 can be compressed, thereby playing a buffering and shock absorbing role; the position of the pressure plate 23 can also be adjusted on the external threaded rod 25, and then the position of the pressure plate 23 can be fixed by the locking nut 26, so that the distance between the shock absorber spring 24 and the pressure plate 23 can be adjusted to achieve different shock absorbing effects.

[0036] A waist-shaped through hole 421 is horizontally arranged on the adjustment slide 42, and the slide shaft 44 is horizontally slidably arranged in the waist-shaped through hole 421. Two buffer sheets 5 are symmetrically arranged in the waist-shaped through hole 421, and the slide shaft 44 is located between the two buffer sheets 5, and the outer peripheral wall of the slide shaft 44 is in conflict with the buffer sheet 5; the buffer sheet 5 includes an upper plate 51; the upper plate 51 and the lower plate 52 are arranged in the waist-shaped through hole 421 from top to bottom, and the upper plate 51 is connected to the top of the waist-shaped through hole 421 by a plurality of connecting bolts 511, and the lower plate 52 is connected to the bottom of the waist-shaped through hole 421 by a plurality of connecting bolts 521; the two ends of the arc opening of the buffer steel plate 53 are respectively connected to the upper plate 51 and the lower plate 52 The arc-shaped top of the buffer steel plate 53 is located at one end close to the sliding shaft 44, and the outer peripheral wall of the sliding shaft 44 conflicts with the arc-shaped top of the buffer steel plate 53; at the same time, when the sightseeing car is bumpy when driving on the road, the wheels and the mounting seat 1 can squeeze the two shock absorber assemblies 4. At this time, the end of the main shock absorber 41 away from the connecting seat 3 rotates on the mounting seat 1, and the end of the main shock absorber 41 away from the mounting seat 1 moves in the adjusting slide groove 42, that is, the sliding shaft 44 moves in the waist-shaped through hole 421, and the sliding shaft 44 can squeeze the two buffer sheets 5 in the waist-shaped through hole 421 (the sliding shaft 44 conflicts with the arc-shaped top of the buffer steel plate 53), so that the buffer steel plate 53 is deformed, thereby playing a buffering role.

[0037] A plurality of threaded holes 1 that are compatible with the connecting bolts 1 511 may also be provided on the top surface of the adjusting slide groove 42, and a plurality of threaded holes 2 that are compatible with the connecting bolts 2 521 may also be provided on the bottom surface of the adjusting slide groove 42, so as to facilitate connecting the upper plate 51 and the lower plate 52 at different positions in the waist-shaped through hole 421 through the connecting bolts 1 511 and the connecting bolts 2 521 respectively (the distance between the upper plate 51 and the lower plate 52 after installation can be adjusted, that is, the distance between the two buffer plates 5 can be adjusted, so that the range of movement of the sliding shaft 44 in the waist-shaped through hole 421 can be adjusted).

[0038] The arc-shaped top of the buffer steel plate 53 has a plurality of anti-slip protrusions 531 evenly distributed along the circumferential direction. When the sliding shaft 44 collides with the arc-shaped top of the buffer steel plate 53 in the waist-shaped through hole 421, the outer peripheral wall of the sliding shaft 44 collides with the anti-slip protrusions 531, which can increase the friction between the outer peripheral wall of the sliding shaft 44 and the arc-shaped top of the buffer steel plate 53, thereby preventing or reducing the sliding of the sliding shaft 44 when it collides with the arc-shaped top of the buffer steel plate 53.

[0039] When the shock-absorbing cylinder assembly 2 is not needed, the position of the pressure plate 23 can be adjusted by rotating on the external threaded rod 25, so that the pressure plate 23 can be adjusted in the direction away from the shock-absorbing spring 24; when the sightseeing car is bumpy during driving, the distance between the mounting seat 1 and the connecting seat 3 is relatively far, and the sightseeing car can be buffered and shock-absorbed under the action of the two shock absorber assemblies 4; and when the bumps are large, that is, when the mounting seat 1 compresses the two shock absorber assemblies 4 with a large stroke, the distance between the mounting seat 1 and the connecting seat 3 is relatively close, and when the pressure plate 23 conflicts with the shock-absorbing spring 24, shock absorption can be performed under the joint action of the shock-absorbing spring 24 and the two shock absorber assemblies 4; the shock-absorbing cylinder assembly 2 can serve as a supplement to the shock-absorbing effect, thereby avoiding the disadvantage that the shock-absorbing effect is affected by the slow rebound of the shock absorber assembly 4 during bumps.

[0040] Embodiment 2

[0041] Based on the first embodiment, Figure 3 As shown, the auxiliary shock absorber 43 includes an auxiliary shock absorber body 431, which is a hydraulic shock absorber. The auxiliary shock absorber body 431 is fixedly arranged on the cylinder of the main shock absorber 41, and the axis of the auxiliary shock absorber body 431 is parallel to the axis of the cylinder of the main shock absorber 41, and the piston rod of the auxiliary shock absorber body 431 is located near one end of the piston rod of the main shock absorber 41; the trigger rod 432 is arranged on the piston rod of the main shock absorber 41, and the position of the trigger rod 432 corresponds to the position of the piston rod of the auxiliary shock absorber body 431; the inner wall of the outer sleeve 433 is provided with an internal thread 2, and the outer part of the piston rod of the auxiliary shock absorber body 431 is provided with an external thread, the outer sleeve 433 is threadedly connected to the outside of the piston rod of the auxiliary shock absorber body 431, and the end of the outer sleeve 433 away from the piston rod of the auxiliary shock absorber body 431 corresponds to the position of the trigger rod 432, and the auxiliary shock absorber body 431 and the outer sleeve 433 are coaxial.

[0042] When the sightseeing car is bumpy when driving on a complex road, the piston rod of the main shock absorber 41 moves in the cylinder of the main shock absorber 41 for buffering, which can simultaneously drive the trigger rod 432 on the piston rod of the main shock absorber 41 to move simultaneously. When the trigger rod 432 moves to conflict with the outer sleeve 433 (that is, the trigger rod 432 moves in the direction close to the outer sleeve 433), the piston rod of the auxiliary shock absorber body 431 can be squeezed, so that the piston rod of the auxiliary shock absorber body 431 moves in the cylinder of the auxiliary shock absorber body 431 for buffering, thereby improving the shock absorption effect on the sightseeing car.

[0043] As needed, the length of the outer sleeve 433 can be adjusted by rotating the outside of the piston rod of the auxiliary shock absorber body 431 (the distance between the outer sleeve 433 and the trigger rod 432 can be adjusted: when the distance between the outer sleeve 433 and the trigger rod 432 is large, the trigger rod 432 can conflict with the outer sleeve 433 when the sightseeing car bumps on a complex road surface with a large amplitude; on the contrary, when the distance between the outer sleeve 433 and the trigger rod 432 is small, the trigger rod 432 can conflict with the outer sleeve 433 when the sightseeing car bumps on a complex road surface with a small amplitude), and then whether to use the auxiliary shock absorber 43 can be selected according to the bumping situation of the sightseeing car on the complex road surface.

[0044] Embodiment 3

[0045] Based on the first embodiment, Figure 1 As shown, the mounting base 1 has limit wheels 6 rotatably arranged at both opposite ends thereof; the limit wheels 6 can provide a certain degree of protection for the mounting base 1. When an obstacle appears on the road surface, the limit wheels 6 can collide with the obstacle when the sightseeing vehicle is traveling, thereby preventing the mounting base 1 from colliding with the obstacle on the road surface and causing damage to the shock absorber cylinder assembly 2 and the shock absorber assembly 4.
