Description

Technical Field

[0001] The invention relates to the field of automobile display stands, in particular to an automobile shock absorption performance display stand. Background Art

[0002] Car display stands are mainly used to place cars at car exhibitions. Traditional car display stands are mainly static displays. The car is stationary on the display stand or rotates with the display stand. Visitors can generally only see the car's shape, interior and some car functions, but cannot intuitively feel the car's shock absorption performance. The car's shock absorption performance seriously affects the car's driving experience, so it is particularly important to display the car's shock absorption performance at car exhibitions. Summary of the invention

[0003] The purpose of the present invention is to provide a car shock absorption performance display stand to overcome the above-mentioned defects in the prior art.

[0004] According to the present invention, a car shock absorption performance display stand includes a pedestal, the interior of the pedestal is hollow, the upper end surface of the pedestal is provided with an opening, two groups of vibration components are arranged in the opening to drive the front and rear wheels of the car to vibrate up and down respectively, the vibration components include a table plate, a central axis and a driving component to drive the table plate to swing, the central axis is arranged in the middle position of the table plate and parallel to the length direction of the pedestal, the table plate is rotatably connected to the outer periphery of the central axis, the central axis is fixed in the pedestal, and the table plate swings back and forth around the central axis under the drive of the driving component.

[0005] Through the above technical solution, the car is placed on two platforms, and the two platforms of the driving component swing back and forth simultaneously or staggered, thereby simulating the bumpy situation when the car is driving, thereby demonstrating the shock absorption performance of the car, so that visitors can judge the shock absorption performance of the displayed car more intuitively.

[0006] Furthermore, two support plates parallel to the width direction of the pedestal are fixed inside the pedestal, and two ends of the central axis are fixed between the two support plates.

[0007] Through the above technical solution, the provision of the support plate is not only conducive to improving the strength of the pedestal, but also realizes the support and fixation of the central axis, ensuring the stability of the table during the swinging process.

[0008] Furthermore, a reinforcement portion is fixedly disposed on the lower end surface of the table plate and is arranged around its edge. Two shaft sleeves are fixed on the lower end surface of the reinforcement portion. The central axis passes through the shaft sleeves and is rotatably connected thereto.

[0009] Through the above technical solution, the provision of the reinforcement part can effectively increase the overall strength of the table top.

[0010] Furthermore, the driving assembly includes a driving plate, a driving shaft and two connecting rods. The driving shaft is fixed between two support plates. The driving shaft is located directly below the central axis. The lower ends of the two connecting rods are respectively rotatably connected to the two ends of the driving plate, and the upper ends are rotatably connected to the lower end surface of the table. The two connecting rods are arranged in parallel. When the driving plate is horizontal, the two connecting rods are perpendicular to the horizontal plane.

[0011] Through the above technical solution, the two connecting rods, the driving plate and the part of the table located between the two connecting rods form a parallelogram, and the table rotates around the central axis, and the driving plate rotates around the driving core shaft, so that the table can be driven to swing by rotating the driving plate.

[0012] Furthermore, magnets are fixed on the lower sides of both ends of the driving plate, and four electromagnets are fixed on the bottom wall of the internal cavity of the base. The four electromagnets are respectively aligned with the magnets on the lower sides of the two driving plates. When the electromagnets are energized, they repel the magnets aligned with them.

[0013] Through the above technical solution, different on-off conditions of the four electromagnets can control the different swing conditions of the two drive plates, thereby simulating different vibrations to which the car is subjected.

[0014] Furthermore, two support blocks symmetrically arranged around the driving shaft are provided on the lower side of each driving plate, and the support blocks are fixed on the bottom wall of the internal cavity of the pedestal. When the upper end of the support block abuts against the driving plate, there is a gap between the magnet and the electromagnet.

[0015] Through the above technical solution, the setting of the support block can effectively prevent the magnet from hitting the electromagnet when the drive plate swings, thereby ensuring the operating life of the magnet and the electromagnet.

[0016] Furthermore, each of the table tops is provided with limit blocks on the left and right sides, the limit blocks are fixed to the upper side walls of the internal cavity of the table, and the limit blocks are slidably connected with a limit seat that can abut against the lower end surface of the table top. Telescopic cylinders are fixed on the end surfaces of both sides of the table, and the four limit seats are respectively fixed on the piston rods of the four telescopic cylinders.

[0017] Through the above technical solution, the telescopic cylinder can control whether the limit blocks are in contact with the lower end surface of the table. When all four limit blocks are in contact with the lower end surface of the table, the two table can maintain a horizontal and stable state.

[0018] Furthermore, two positioning seats are provided on the lower side of the table and located on both sides of the driving assembly. A number of positioning plates are fixedly provided at both ends of the positioning seat along the length direction of the table. A number of through slots are opened in the table and are evenly distributed along the width direction of the table. A number of the positioning plates penetrate the through slots respectively. A connecting rod is fixed to the upper end of the positioning plate on the same side, and a "V" shape is formed between the positioning plates on both sides. A fixing rod fixed to the lower end surface of the table is provided on the lower side of the positioning seat, and a motor is fixed to the lower end surface of the fixing rod. A nut is fixed in the positioning seat, and a screw is threadedly connected to the inner thread of the nut, and the lower end of the screw is fixed to the rotating shaft of the motor.

[0019] Through the above technical solution, the motor drives the screw to rotate, thereby enabling the positioning seat to move upward or downward, thereby driving the positioning plate on the corresponding side to abut against the outer periphery of the automobile tire, thereby limiting the rolling of the automobile tire.

[0020] Furthermore, each of the positioning seats is provided with a fixing seat fixed on the upper end surface of the table top on both sides, and a limiting plate is slidably engaged in the fixing seat, and a clamp is fixed to the end of the limiting plate close to the positioning seat, and the clamp is located between the two fixing seats on the corresponding sides, and strapping belts are fixed to the upper ends of the clamps, and the two adjacent strapping belts are connected by buckles, and through holes evenly distributed along the length direction of the limiting plate are opened in the limiting plate, and a limiting pin that can pass through the through hole is slidably connected in the fixing seat.

[0021] Through the above technical solution, after the strapping belt passes through the automobile tire, the strapping belt is clamped by the buckle, so that the automobile tire is fixed on the table plate, ensuring the stability of the automobile tire during the swinging process of the table plate.

[0022] The beneficial effects of the present invention are as follows: a car is placed on two platforms, the rolling of the tires is restricted by a positioning plate, and the tires are fixed to the platforms by a strapping belt, and the two driving plates are driven to swing back and forth by different on and off states of four electromagnets, thereby causing the two platforms to swing back and forth at the same time, thereby simulating the bumpy conditions of the car when driving, thereby demonstrating the shock absorbing performance of the car, so that visitors can more intuitively judge the shock absorbing performance of the displayed car.

As used herein, the terms up and down and left and right are not limited to their strict geometric definitions, but include reasonable and inconsistent tolerances for machining or human errors. The specific features of the automobile shock absorption performance display stand are described in detail below: An embodiment of the present invention: Reference Figure 1-Figure 7 The present invention provides a car shock absorption performance display stand, including a pedestal 10, the pedestal 10 is hollow inside, an opening is formed on the upper end surface of the pedestal 10, two groups of vibration components are arranged in the opening to respectively drive the front and rear wheels of the car to vibrate up and down, the vibration components include a table 20, a central axis 12 and a driving component for driving the table 20 to swing, the central axis 12 is arranged in the middle of the table 20 and parallel to the length direction of the pedestal 10, the table 20 is rotatably connected to the outer periphery of the central axis 12, the central axis 12 is fixed in the pedestal 10, and the table 20 swings back and forth around the central axis 12 under the drive of the driving component.

[0027] Reference Figure 2 Two support plates 11 parallel to the width direction of the pedestal 10 are fixed inside, and both ends of the central axis 12 are fixed between the two support plates 11 .

[0028] Reference Figure 2 , Figure 7 The lower end surface of the table 20 is fixed with a reinforcing portion 23 arranged around its edge. Two shaft sleeves 21 are fixed to the lower end surface of the reinforcing portion 23. The central shaft 12 passes through the shaft sleeves 21 and is rotatably connected thereto.

[0029] Reference Figure 3 , Figure 4 , Figure 5 The driving assembly includes a driving plate 40, a driving spindle 41 and two connecting rods 43. The driving spindle 41 is fixed between the two supporting plates 11. The driving spindle 41 is located directly below the central axis 12. The lower ends of the two connecting rods 43 are rotatably connected to the two ends of the driving plate 40, and the upper ends thereof are rotatably connected to the lower end surface of the table 20. The two connecting rods 43 are arranged in parallel. When the driving plate 40 is horizontal, the two connecting rods 43 are perpendicular to the horizontal plane. Magnets 45 are fixed on the lower side surfaces of the two ends of the driving plate 40. Four electromagnets 44 are fixed on the bottom wall of the internal cavity of the table 10. The four electromagnets 44 are aligned with the magnets 45 on the lower side surfaces of the two driving plates 40, respectively. The electromagnets 44 After power is turned on, the magnet 45 aligned with it is repelled. Two support blocks 42 symmetrically arranged with the driving core shaft 41 as the center are arranged on the lower side of each driving plate 40. The support blocks 42 are fixed on the bottom wall of the internal cavity of the pedestal 10. When the upper end of the support block 42 abuts against the driving plate 40, there is a gap between the magnet 45 and the electromagnet 44. Limit blocks 61 are arranged on the left and right sides of each table 20. The limit blocks 61 are fixed to the upper side wall of the internal cavity of the pedestal 10. A limit seat 60 that can abut against the lower end surface of the table 20 is slidably connected in the limit block 61. Telescopic cylinders 62 are fixed on the end surfaces on both sides of the pedestal 10, and the four limit seats 60 are respectively fixed on the piston rods of the four telescopic cylinders 62.

[0030] Reference Figure 4 , Figure 6 , Figure 7Two positioning seats 50 located on both sides of the driving assembly are provided on the lower side of the table 20. A number of positioning plates 57 are fixedly provided at both ends of the positioning seat 50 along the length direction of the table 10. A number of through slots 22 equidistantly distributed along the width direction of the table 10 are opened in the table 20. The positioning plates 57 respectively penetrate the through slots 22. A connecting rod 56 is fixedly provided on the upper end of the positioning plate 57 on the same side. The positioning plates 57 on both sides are in a "V" shape. A fixing rod 51 fixed to the lower end surface of the table 20 is provided on the lower side of the positioning seat 50. A motor 53 is fixed to the lower end surface of the fixing rod 51. A nut 55 is fixed in the positioning seat 50. A screw 54 is threadedly connected to the nut 55. The upper end of the screw 54 is rotatably connected to the lower end surface of the table 20, and the lower end of the screw 54 is fixed to the rotating shaft of the motor 53.

[0031] Reference Figure 4 , Figure 5 Each positioning seat 50 is provided with a fixing seat 34 fixed on the upper end surface of the table 20 on both sides, and a limiting plate 33 is slidably fitted in the fixing seat 34. A clamping plate 32 is fixed to the end of the limiting plate 33 close to the positioning seat 50. The clamping plate 32 is made of rubber material. The clamping plate 32 is located between the two fixing seats 34 on the corresponding side. A strapping belt 30 is fixed to the upper end of the clamping plate 32. The adjacent two strapping belts 30 are connected by a buckle. Through holes evenly distributed along the length direction of the limiting plate 33 are opened in the limiting plate 33, and a limiting pin 31 that can pass through the through hole is slidably connected in the fixing seat 34.

[0032] In the initial state, the four telescopic cylinders 62 are in an extended state, and the piston rods therein push the limit seat 60 out of the limit block 61, so that the four limit seats 60 are all in contact with the lower end surface of the table 20, thereby ensuring that the two table plates 20 are in a horizontal state and the upper end surface of the table plate 20 is flush with the upper end surface of the base 10.

[0033] At this time, the car is pushed along the slopes at both ends of the pedestal 10 to the upper end surface of the pedestal 10, and the tires on both sides of the car are aligned with the connecting rods 56 respectively. When the car tires are located between the two clamping plates 32, the motor 53 is started to rotate the screw 54, thereby driving the nut 55 to move upward, and then the positioning seat 50 moves upward, thereby driving the positioning plate 57 on the corresponding side to move upward until the positioning plate 57 abuts against the outer periphery of the car, thereby limiting the rolling of the car tires.

[0034] Then, after passing the strapping belt 30 through the automobile tire, pull out the limit pin 31 upwards, push the limit plate 33 towards the tire, so that the clamping plates 32 on both sides of the tire abut against the side surfaces of the tire. At this time, insert the limit pin 31 into the through hole on the limit plate 33 to ensure that the two adjacent clamping plates 32 clamp the tire, and tighten the two adjacent strapping belts 30 through the buckle to fix the automobile tire on the platform 20.

[0035] The car is now placed on the pedestal 10 in a static display.

[0036] When the shock absorption performance of the automobile needs to be demonstrated, the four telescopic cylinders 62 are started, so that the four telescopic cylinders 62 are shortened, and the four limit seats 60 are retracted into the limit blocks 61 on the corresponding sides under the pulling of the piston rods of the telescopic cylinders 62 on the corresponding sides, and the four limit seats 60 are disengaged from the abutment with the platform 20.

[0037] Taking the driving shaft 41 as the boundary, when the two electromagnets 44 located on one side of the driving shaft 41 are energized first, the two electromagnets 44 repel the magnets 45 on the corresponding side, and then one end of the driving plate 40 where the electromagnets 44 on that side are fixed is lifted up and the other end falls down. Then the two electromagnets 44 located on the other side of the driving shaft 41 are energized again and the two electromagnets 44 originally energized are de-energized. Then, the lifted end of the driving plate 40 falls down and the fallen end is lifted up, and so on and so forth, so that the two platform plates 20 swing back and forth at the same time, thereby realizing the simultaneous display of the shock absorbing performance of the shock absorbing system on the same side of the vehicle.

[0038] Reference Figure 5 When the electromagnet 44 on the left side of one driving assembly is energized and the electromagnet 44 on the right side is de-energized, and the electromagnet 44 on the right side of another driving assembly is energized and the electromagnet 44 on the left side is de-energized, the two platform plates 20 are caused to swing back and forth alternately, thereby separately demonstrating the shock absorbing performance of the shock absorbing system at the four tires of the automobile.

[0039] In summary, the shock absorption performance of the car can be demonstrated through the reciprocating swing of the two platform plates 20, and visitors can intuitively feel the shock absorption performance of the car by observing the vibration of the car.

[0040] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention.
