[0004] The inventor discovered the following problems in the prior art during the implementation of this application: Although the above-mentioned comparative patent provides an integrated storable pneumatic boarding assist device by providing a storage box, a step frame, a pedal and a baffle, it is necessary to provide a corresponding storage box on the lower skirt of the car, which results in that when it is applied to a car driving simulator, not only the addition of components of the real car cockpit may interfere with the simulation results, but also when the motion system controls the real car cockpit to produce a certain lateral tilt instead of keeping it horizontal, it is difficult to ensure a good use effect. Therefore, those skilled in the art provide a boarding device for a car driving simulator to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a boarding device for a car driving simulator, which realizes the precise lifting and lowering and lateral tilt adjustment of the platform and the step through a motor-driven screw and jack system, and at the same time uses a limit mechanism to fix the relative position of the platform and the step, and uses an auxiliary support mechanism to automatically adjust through a gas rod system to assist in maintaining the balance and stability of the device at different heights and angles.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a boarding device for a car driving simulator, comprising a platform, a stepping platform, a lifting mechanism, an auxiliary support mechanism and a limiting mechanism, the platform comprising a lower plate, the upper end of the lower plate near one side is fixedly provided with three slide rails equidistantly, the stepping platform comprising an upper plate, the lower end of the upper plate near one side is provided with three slide grooves equidistantly;

[0007] The lifting mechanism includes four jacks and two screw rods. The two screw rods are axially symmetrical and are respectively threaded with four nuts. The four nuts on each screw rod are fixed with a main gas rod in a group of two. The auxiliary support mechanism includes six support blocks. The centers of the lower ends of the six support blocks are respectively ball-hinged and connected with auxiliary gas rods. The limiting mechanism includes a rack. The lower end of the rack is fixed to a position on the upper end of the lower plate near the front of the upper plate, and the upper end of the rack is meshed with a gear. The gear passes through both sides and is slidably provided with a limiting pin near the edge.

[0008] Furthermore, the three slide rails are slidably arranged in the three slide grooves respectively.

[0009] Furthermore, one end of the two screw rods is fixedly connected to a motor respectively, one end of the two screw rods is fixedly connected to the output ends of the two motors respectively, and the inner sides of the two motors are fixedly arranged to the front end of the lower plate through a bracket.

[0010] Furthermore, a limiting groove is opened near the front end position on one side of the upper plate, and the gear passes through the center and is rotated to the center of the limiting groove through a rotating shaft. The limiting groove is a plurality of cylindrical grooves in a centrally symmetrical and staggered annular array, and each of the cylindrical grooves has the same size as the cylindrical size at the inner end of the limiting pin, and the diameter of the cylindrical part in the middle of the limiting pin is smaller than the cylindrical parts at both ends.

[0011] Furthermore, the upper ends of the four jacks are respectively connected to fixed blocks through support ball hinges, and the upper ends of the four fixed blocks are axially symmetrically fixed to one side of the middle of the inner surface of the upper end of the lower plate, and the four jacks are respectively connected to the two sides of the eight nuts by rotating shafts at both ends.

[0012] Furthermore, the six support blocks are respectively fixed with their upper ends to the lower end of the lower plate near the four corners and the middle of both sides near the edges, the four of the six auxiliary air rods near the four corners of the lower plate are respectively fixedly connected to the nearest one of the four main air rods near one end through air pipes and hoses, and the two of the six auxiliary air rods located on both sides of the middle of the lower plate are fixedly connected to each other through air pipes and hoses.

[0013] Furthermore, a truncated cone-shaped support column is fixedly provided at the lower ends of the four jacks, and threaded interfaces are respectively provided at the centers of the lower ends of the four truncated cone-shaped support columns and the six auxiliary gas rods.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model proposes a boarding device for a car driving simulator, which drives two screw rods respectively through two motors to flexibly control the lifting and tilting operations of the platform and the step. When the user needs the platform and the step to be level, it only needs to start the two motors synchronously so that the two screw rods drive the corresponding nuts to make the corresponding jacks extend and retract at the same time, thereby achieving a smooth lifting operation; and when the tilt angle of the platform and the step needs to be adjusted, the motor on one side can be started separately so that the jack on that side is raised or lowered accordingly, thereby forming a specific tilt angle. Not only does it simplify the operation process, but it also ensures the accuracy of the adjustment. In addition, the limit mechanism realizes the smooth sliding and precise positioning of the upper plate on the lower plate by means of the slide rail, slide groove, gear and limit groove arranged between the upper plate and the lower plate. After determining the reasonable gap between the upper platform of the motion system and the step boss of the upper plate, the user can fix the position of the upper plate and the lower plate through the limit pin, thereby preventing displacement caused by vibration or other external forces during use, and ensuring the safety of the user when getting on and off the vehicle.

[0016] 2. The utility model proposes a boarding device for a car driving simulator, which further improves the stability and safety of the boarding device through the design of an auxiliary support mechanism and a limit mechanism. The four auxiliary gas rods near the four corners of the lower end of the lower plate are connected to the corresponding main gas rods through air pipes and hoses. When a certain jack is extended or retracted, the corresponding auxiliary gas rod can automatically adjust to maintain the balance and stability of the device. In particular, when the platform and the step are operated at different heights and angles, the auxiliary support mechanism can provide reliable support to ensure that the device will not tip over or become unstable.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 The utility model provides an embodiment: a boarding device for a car driving simulator, comprising a platform 1, a stepping platform 2, a lifting mechanism 3, an auxiliary support mechanism 4 and a limiting mechanism 5, wherein the platform 1 comprises a lower plate 101, the stepping platform 2 comprises an upper plate 201, the lifting mechanism 3 comprises four jacks 301 and two screw rods 303, the auxiliary support mechanism 4 comprises six support blocks 402, and the limiting mechanism 5 comprises a rack 503;

[0029] Specifically, due to the limitation of the installation and use site, the upper and lower platforms of the motion system under the cabin of the actual vehicle are relatively large in size and are not suitable for getting on and off the vehicle with a boarding ladder. The boarding device includes a separable platform 1 and a step 2 on the upper and lower layers. The frame of the lower fixed boarding platform 1 is welded and formed by carbon steel rectangular tubes, the upper plane is covered with an anti-slip patterned steel plate, the side is well covered with a stainless steel plate, and the rear side extends out at a corner to place the upper step 2. The upper movable step 2 is made of an aluminum alloy square tube, the upper plane is covered with an aluminum alloy patterned plate, and the side and the ground are well covered with a stainless steel plate of a certain thickness. The step boss on the rear side close to the rear wheel is adjusted to the same height as the motion system each time. The upper platform is flat, which is convenient for users to get on and off the vehicle from the rear door. The lifting mechanism 3 is controlled by four jacks 301 in groups of two, so as to adjust the platform 1 and the step 2 to a certain height or a certain tilt angle, so as to adapt to the different vertical heights and tilt angles of the motion system for the convenience of users to get on and off the vehicle. The auxiliary support mechanism 4 well assists the lifting mechanism 3 to maintain the platform 1 and the step 2 to maintain a stable height, tilt angle and balance. The limiting mechanism 5 plays a good role in fixing the relative position of the platform 1 and the step 2. The device can be axially symmetrically arranged on both sides of the real vehicle cabin, so that users can get on and off the vehicle safely and conveniently from any of the four doors on both sides.

[0030] Reference Figure 3 : Three slide rails 102 are fixedly arranged at equal intervals on the upper end of the lower plate 101 near one side;

[0031] Specifically, the three slide rails 102 are fixedly arranged in sequence and equidistantly, which can provide a more stable fixing effect for the upper plate 201 of the platform 2 compared to the use of a single slide rail 102 .

[0032] Reference Figure 3 , Figure 4 and Figure 8 : Three slide grooves 202 are equidistantly provided at the lower end of the upper plate 201 near one side, and three slide rails 102 are respectively slidably arranged inside the three slide grooves 202. A limiting groove 203 is provided near the front end of one side of the upper plate 201. The limiting groove 203 is a plurality of columnar grooves in a centrally symmetrical and staggered annular array, and each columnar groove has the same size as the cylindrical end of the inner side of the limiting pin 501;

[0033] Specifically, the three slide grooves 202 and the three slide rails 102 have corresponding sizes and fit well, so as to well connect the lower plate 101 of the platform 1 and the upper plate 201 of the step 2, and the upper plate 201 can be smoothly slid on the lower plate 101 according to actual needs, thereby adjusting the gap between the step boss of the upper plate 201 and the upper platform of the motion system, which is convenient for users to get on and off the vehicle safely. The multiple columnar grooves of the limit groove 203 are in a centrally symmetrical and staggered annular array, so that the limit pin 501 has sufficiently fine limiting accuracy. Each columnar groove has the same size as the cylinder at the inner end of the limit pin 501, so that the limit pin 501 plays a good fixing and limiting role when it is inserted into a columnar groove in the limit groove 203.

[0034] Reference Figure 2 , Figure 5 and Figure 6 : The rod bodies of the two screw rods 303 are axially symmetrical and are respectively threaded with four nuts 304. The four nuts 304 on each screw rod 303 are fixedly provided with a main gas rod 302 in a group of two. One end of the two screw rods 303 is respectively fixedly connected to a motor 306. One end of the two screw rods 303 is respectively fixedly connected to the output end of the two motors 306. The inner sides of the two motors 306 are fixedly provided to the front end of the lower plate 101 through a bracket. The upper ends of the four jacks 301 are respectively connected to the fixed blocks 305 through the support ball hinge. The upper ends of the four fixed blocks 305 are axially symmetrical and respectively fixedly provided to the middle side of the inner surface of the upper end of the lower plate 101. The four jacks 301 respectively connect the two ends to the two sides of the eight nuts 304 through a rotating shaft. The lower ends of the four jacks 301 are fixedly provided with a truncated cone support.

[0035] Specifically, when only the platform 1 and the step 2 need to be raised or lowered without generating a lateral tilt, the user starts the two motors 306 and synchronously drives the two screw rods 303 to rotate at the same angle, and the four nuts 304 on each screw rod 303 drive the jack 301 rotatably connected thereto to extend or contract in the vertical direction, and the lower plate 101 and the upper plate 201 rise and fall accordingly, which well matches the height of the upper platform of the motion system and is convenient for users to get on and off the vehicle; when the platform 1 and the step 2 need to generate a certain lateral tilt angle, the user starts a single motor 306 to drive the screw rod 303 on the same side to rotate, and the four nuts 304 threadedly connected to the screw rod 303 move closer to or farther away from each other in groups of two, thereby driving the jack 301 rotatably connected thereto to extend or contract in the vertical direction, making the heights of the two sides different, thereby forming a certain lateral tilt angle, and the truncated cone-shaped pillars fixed at the lower ends of the four jacks 301 play a good stabilizing supporting role.

[0036] Reference Figure 2 and Figure 5The auxiliary support mechanism 4 comprises six support blocks 402, the six support blocks (402) respectively fix their upper ends to the lower end of the lower plate (101) near the four corners and the middle of both sides near the edge, the lower ends of the six support blocks 402 are respectively connected to auxiliary gas rods 401 by ball hinges, four of the six auxiliary gas rods 401 near the four corners of the lower plate 101 are respectively fixedly connected to the rod body of the nearest one of the four main gas rods 302 near one end through air pipes and hoses, two of the six auxiliary gas rods 401 located on both sides of the middle of the lower plate 101 are fixedly connected to each other through air pipes and hoses, and threaded interfaces are respectively provided at the centers of the lower ends of the four truncated cone pillars and the six auxiliary gas rods 401;

[0037] Specifically, when each jack 301 is extended in the vertical direction, the main gas rod 302 near the lower end thereof is shortened and the compressed air is discharged into the auxiliary gas rod 401 connected thereto through the air pipe and the hose to extend it. Similarly, when each jack 301 is contracted in the vertical direction, the corresponding auxiliary gas rod 401 is shortened accordingly, and the two auxiliary gas rods 401 in the middle of the lower plate 101 are connected to each other through the air pipe and the hose, and shorten or lengthen accordingly when the other party is extended and contracted, playing a good adaptive stable balancing role. The four truncated cone-shaped pillars and the six auxiliary gas rods 401 are well threadedly connected to the bottom frame of the motion system through the threaded interface at the lower end, and the positioning is reliable and the connection with the motion system is stable.

[0038] In actual applications, for example, when the jacks 301 on both sides are synchronously extended to the same degree in the vertical direction, the corresponding main gas rod 302 is shortened accordingly to make the connected auxiliary gas rod 401 extend, so that the whole device maintains balance and rises stably. For another example, when only one side of the jack 301 is raised, the corresponding main gas rod 302 is shortened accordingly to make the auxiliary gas rod 401 connected to the same side extend, so that the whole device maintains a certain heel angle.

[0039] Reference Figure 1 , Figure 7 and Figure 8 : The lower end of the rack 503 is fixedly set to the front of the upper end of the lower plate 101 near the upper plate 201, and the upper end of the rack 503 is meshed with a gear 502. The gear 502 passes through both sides and is slidably set with a limit pin 501 near the edge. The gear 502 passes through the center and is rotated to the center of the limit slot 203 through the rotating shaft. The diameter of the cylindrical part in the middle of the limit pin 501 is smaller than the cylindrical parts at both ends;

[0040] Specifically, the upper plate 201 slides well on the three slide rails 102 of the lower plate 101 through the three slide grooves 202, and the gear 502 that is well meshed with the rack 503 rotates well accordingly. After the relative position of the upper plate 201 and the lower plate 101 is determined according to the reasonable gap between the upper platform and the step boss of the upper plate 201, the limit pin 501 is slidably inserted into the columnar groove at the corresponding position in the limit groove 203, so as to fix the relative position of the upper plate 201 and the lower plate 101 well.

[0041] Working principle: when in use, according to actual needs, when only the platform 1 and the step 2 need to be raised or lowered without generating a lateral tilt, the user can start the two motors 306 and synchronously drive the two screw rods 303 to rotate at the same angle, and the four nuts 304 on each screw rod 303 drive the jack 301 rotatably connected thereto to extend or contract in the vertical direction, and the lower plate 101 and the upper plate 201 rise and fall accordingly, which well matches the height of the upper platform of the motion system and is convenient for users to get on and off the vehicle; when the platform 1 and the step 2 need to generate a certain lateral tilt angle, the user starts a single motor 306 to drive the screw rod 303 on the same side to rotate, and the four nuts 304 threadedly sleeved with the screw rod 303 move closer to or farther away from each other in groups of two, thereby driving the jack 301 rotatably connected thereto to extend or contract in the vertical direction, making the heights of the two sides different, thereby forming a certain lateral tilt angle;

[0042] Secondly, when each jack 301 is stretched in the vertical direction, the main air rod 302 near the lower end thereof is shortened and the compressed air is discharged into the auxiliary air rod 401 connected thereto through the air pipe and the hose to extend it. Similarly, when each jack 301 is contracted in the vertical direction, the corresponding auxiliary air rod 401 is shortened accordingly, and the two auxiliary air rods 401 in the middle of the lower plate 101 are connected to each other through the air pipe and the hose, and shorten or lengthen accordingly when the other party stretches and contracts, playing a good adaptive stable balancing role. In practical applications, for example, when only the jacks 301 on both sides are synchronously stretched to the same degree in the vertical direction, the corresponding main air rod 302 is shortened accordingly to make the connected auxiliary air rod 401 extend, so that the whole device is balanced and stably raised. For another example, when only one side of the jack 301 is raised, the corresponding main air rod 302 is shortened accordingly to make the auxiliary air rod 401 connected to the same side extend, so that the whole device maintains a certain heel angle.

[0043] In addition, the upper plate 201 slides well on the three slide rails 102 of the lower plate 101 through the three slide grooves 202, and the gear 502 that is well meshed with the rack 503 rotates well accordingly. After the relative position of the upper plate 201 and the lower plate 101 is determined according to the reasonable gap between the upper platform and the step boss of the upper plate 201, the limit pin 501 is slidably inserted into the columnar groove at the corresponding position in the limit groove 203, so that the relative position of the upper plate 201 and the lower plate 101 is well fixed.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
