DETAILED DESCRIPTION

[0029] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1 As shown:

[0031] An adjustable suspension system for an intelligent rail vehicle using mixed reality technology includes an intelligent rail vehicle body 101 and driving wheels 102 arranged at the four corners of the intelligent rail vehicle body 101.

[0032] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "in order to improve the driving stability and comfort of the current intelligent rail vehicle, the independent suspension of the intelligent rail vehicle is generally adjusted according to different road conditions. However, in the process of suspension adjustment, it is difficult to accurately ensure the consistency and performance of each suspension unit. Moreover, the adjustment by turning the wrench has an inconvenient range of motion, low adjustment efficiency, and reduced suspension adjustment effect." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve.

[0033] More specifically:

[0034] like Figures 1-4 As shown:

[0035] In combination with the above content: a first suspension arm 103 is fixedly installed on the lower surface of the intelligent rail vehicle body 101 near the driving wheel 102;

[0036] The bottom end of the first suspension arm 103 is hinged with a second suspension arm 104;

[0037] A hydraulic telescopic member 105 is provided between the first suspension arm 103 and the second suspension arm 104, and a spring 106 is wound around the outside of the hydraulic telescopic member 105;

[0038] An upper cover 107 hinged to the first suspension arm 103 is fixedly mounted on one end of the hydraulic telescopic member 105, and a lower support rod 108 hinged to the second suspension arm 104 is fixedly mounted on the other end of the hydraulic telescopic member 105. A threaded sleeve 109 is mounted on the hydraulic telescopic member 105, and a threaded cap 110 is threadedly connected to the surface of the threaded sleeve 109.

[0039] The screw cap 110 is provided with a unidirectional driving mechanism 2, which can drive the screw cap 110 to rotate in a single direction.

[0040] The unidirectional drive mechanism 2 includes a rotating disk 201 that rotates on the bottom of the threaded cap 110 via a bearing, a screw 204 that is hinged to the surface of the rotating disk 201 via a hinge seat, and a latch 202 that is provided on the rotating disk 201 near one side of the screw 204. A center hole is provided at the center of the rotating disk 201.

[0041] A second spring 203 is wound around the surface of the latch 202. The two ends of the second spring 203 are fixedly connected to the rotating disk 201 and the latch 202 respectively. The edge surface of the threaded cap 110 is provided with multiple groups of equidistantly arranged locking grooves 208 that match the latch 202.

[0042] The surface of the rotating disk 201 is provided with a sliding hole adapted to fit the latch 202. The latch 202 and the rotating disk 201 are slidably connected through the sliding hole. The latch 202 is inserted into one of the sets of lock slots 208.

[0043] A fixing plate 111 is fixed to the surface of the lower support rod 108;

[0044] The fixing plate 111 is provided with an adjusting and positioning mechanism 3 which can accurately measure the position of the threaded cap 110;

[0045] The adjustment and positioning mechanism 3 includes a push rod 301 sliding on the fixed plate 111 and a spring 304 wound around the surface of the push rod 301;

[0046] The two ends of the spring 304 are fixedly connected to the fixed disk 111 and the ejector rod 301 respectively. A strip groove is provided on the surface of the ejector rod 301. The ejector rod 301 is provided with a scale line 303 in the strip groove. A movable hole is provided inside the fixed disk 111 to match the ejector rod 301. The ejector rod 301 and the fixed disk 111 are slidably connected through the movable hole.

[0047] A connecting seat is fixedly mounted on the bottom end of the second suspension arm 104 , and the driving wheel 102 is rotatably connected to the connecting seat via a driving shaft.

[0048] In this embodiment, the adjustable suspension system of the intelligent rail vehicle of the mixed reality technology is used. When the intelligent rail vehicle body 101 adjusts the suspension according to different road conditions, the screw rod 204 is first swung, thereby driving the rotating disk 201 to rotate clockwise. Since the latch 202 is inserted into the locking groove 208 provided in the threaded cap 110, the connection between the rotating disk 201 and the threaded cap 110 is achieved. When the rotating disk 201 is rotated, the threaded cap 110 is driven to rotate. Since the threaded cap 110 is threadedly connected to the threaded sleeve 109, the threaded cap 110 moves on the threaded sleeve 109. By driving the movement of the threaded cap 110, the spring 106 is squeezed to adjust the preload of the spring 106. Increasing the preload makes the suspension harder, while reducing the preload makes the suspension softer.

[0049] After the threaded cap 110 is rotated to a certain angle, the latch 202 is pulled at the same time, so that the latch 202 stretches the spring 203, so that the latch 202 disengages from the lock groove 208, thereby releasing the connection and locking between the rotating disk 201 and the threaded cap 110. At this time, the screw 204 drives the rotating disk 201 to rotate counterclockwise to a certain angle. During the rotation process, the latch 202 is loosened, so that the latch 202 fits the edge surface of the threaded cap 110. When the rotating disk 201 rotates to a certain angle, the spring 203 in the stretched state is in the latch 202 state. During the alignment process of the pin 202 and the locking groove 208, the threaded cap 110 will not rotate in the opposite direction. After the rotating disk 201 rotates in the opposite direction by an angle, the rotating disk 201 is driven to rotate clockwise again. Through this operation, the threaded cap 110 is driven by a wrench (not shown in the figure) to rotate a certain angle, and then the wrench is disengaged from the threaded cap 110 again, and then the wrench is engaged and rotated again. Frequent operations will slow down the rotation efficiency of the threaded cap 110, and at the same time solve the problem of the wrench being inconvenient to rotate, further improve the use effect of the device, and make the rotation operation of the threaded cap 110 more convenient;

[0050] When the threaded cap 110 moves up or down, it can drive the rotating disk 201 to move synchronously. At this time, the spring three 304 in the stretched state drives the ball 302 on the ejector rod 301 to always contact the surface of the rotating disk 201. When the rotating disk 201 moves, the ejector rod 301 will slide on the fixed disk 111. By observing the scale line 303 on the ejector rod 301, the moving distance of the ejector rod 301 can be accurately judged, and the position of the rotating disk 201 and the threaded cap 110 can be indirectly determined at this time. Through this structure, it can ensure that the stress of the four groups of springs 106 are at the same parameter. The intelligent rail car body 101 can be more stable during driving, reducing the vibration transmitted to the car body, thereby improving the comfort of movement, and can evenly bear the force, thereby improving the response speed of the intelligent rail car body 101.

[0051] It should be noted that the hydraulic telescopic member 105 includes a cylinder, a piston, a piston rod, a seal, a damping valve, hydraulic oil and a guide sleeve, and its specific structure and function can be achieved by conventional means.

[0052] The threaded sleeve 109 is fixed on the surface of the cylinder body, the lower support rod 108 is fixedly installed on the bottom end of the cylinder body, and the upper cover seat 107 is fixedly installed on one end of the piston rod.

[0053] Going further;

[0054] In an optional embodiment, the upper portion of the threaded cap 110 is provided with a second abutment plate 207 which rotates via a bearing, and both ends of the first spring 106 respectively abut against the upper cover seat 107 and the second abutment plate 207 .

[0055] In this embodiment, when the threaded cap 110 is rotated, the second contact plate 207 and the threaded cap 110 are rotatably connected. The setting of the second contact plate 207 reduces the resistance generated by the contact between one end of the spring 106 and the threaded cap 110, thereby improving the smoothness of the rotation of the threaded cap 110.

[0056] Going further;

[0057] In an optional embodiment, the surface of the screw rod 204 is threadedly connected to a threaded barrel 205, and the bottom end of the threaded barrel 205 is rotated by a bearing to form a resistance plate 206.

[0058] In this embodiment: after the stress adjustment of the spring 106 is completed, the suspension adjustment is achieved, and then the screw 204 is flipped so that the interference disk 1 206 on the threaded barrel 205 corresponds to the fixed disk 111, and then the threaded barrel 205 is rotated, thereby driving the interference disk 1 206 to contact the fixed disk 111 and squeeze the fixed disk 111. At this time, the squeezing force generated by the interference disk 1 206 and the fixed disk 111 can reduce the rotation of the threaded cap 110 driven by the rotating disk 201 on the threaded sleeve 109.

[0059] Going further;

[0060] In an optional embodiment, a rolling groove is provided at the top of the ejector rod 301, and a ball 302 is provided in the rolling groove. The ball 302 can roll in the rolling groove provided in the ejector rod 301, and the spring three 304 is in a stretched state. The ball 302 on the ejector rod 301 is driven by the spring three 304 to always contact the top of the rotating disk 201.

[0061] In this embodiment, the provision of the ball 302 can reduce the friction between the rotating disk 201 and the ejector rod 301 , thereby improving the rotation effect of the ejector rod 301 .

[0062] The working principle and use process of the utility model: The adjustable suspension system of the intelligent rail car of the mixed reality technology is used. When the intelligent rail car body 101 adjusts the suspension according to different road conditions, the screw rod 204 is first swung, thereby driving the rotating disk 201 to rotate clockwise. Since the latch 202 is inserted into the locking groove 208 provided in the threaded cap 110, the connection between the rotating disk 201 and the threaded cap 110 is realized. When the rotating disk 201 is rotated, the threaded cap 110 is driven to rotate. Since the threaded cap 110 and the threaded sleeve are connected, the rotating disk 201 is rotated. 109 is threadedly connected, thereby making the threaded cap 110 move on the threaded sleeve 109, and by driving the movement of the threaded cap 110, the spring 106 is squeezed to adjust the preload of the spring 106. By increasing the preload, the suspension will be harder, and by reducing the preload, the suspension will be softer. When the threaded cap 110 is rotated, the resistance generated by the contact between one end of the spring 106 and the threaded cap 110 is reduced by the setting of the friction disk 207, thereby improving the smoothness of the rotation of the threaded cap 110. After the threaded cap 110 is rotated to a certain angle, the latch 202 is pulled at the same time, so that the latch 202 stretches the spring 203, so that the latch 202 disengages from the lock groove 208, thereby releasing the connection and locking between the rotating disk 201 and the threaded cap 110. At this time, the screw 204 drives the rotating disk 201 to rotate counterclockwise to a certain angle. During the rotation process, the latch 202 is loosened, so that the latch 202 fits the edge surface of the threaded cap 110. When the rotating disk 201 rotates to a certain angle, during this process, the spring 203 in the stretched state is During the process of the latch pin 202 and the locking groove 208 being aligned, the threaded cap 110 will not rotate in the opposite direction. After the rotating disk 201 rotates in the opposite direction by a certain angle, the rotating disk 201 is driven to rotate clockwise again. Through this operation, the threaded cap 110 is driven by a wrench (not shown in the figure) to rotate a certain angle, and then the wrench is disengaged from the threaded cap 110 again, and then the wrench is engaged and rotated again. Frequent operation will slow down the rotation efficiency of the threaded cap 110, and at the same time solve the problem of the wrench being inconvenient to rotate, further improve the use effect of the device, and make the rotation operation of the threaded cap 110 more convenient;When the threaded cap 110 moves up or down, it can drive the rotating disk 201 to move synchronously. At this time, the spring three 304 in the stretched state drives the ball 302 on the ejector rod 301 to always contact the surface of the rotating disk 201. When the rotating disk 201 moves, the ejector rod 301 will slide on the fixed disk 111. By observing the scale line 303 on the ejector rod 301, the moving distance of the ejector rod 301 can be accurately judged, and the position of the rotating disk 201 and the threaded cap 110 can be indirectly determined at this time. Through this structure, the stress of the four groups of springs 106 can be ensured to be at the same parameter. The intelligent rail car body 101 can be more stable during driving, reducing the vibration transmitted to the car body, thereby improving the comfort of movement. Moreover, it can evenly distribute force, improving the response speed of the intelligent rail vehicle body 101. The provision of the ball bearing 302 can reduce the friction between the rotating disk 201 and the ejector rod 301, thereby improving the rotation effect of the ejector rod 301. After the stress of the spring 106 is adjusted, thereby achieving suspension adjustment, the screw rod 204 is then flipped so that the contact disk 1 206 on the threaded barrel 205 corresponds to the fixed disk 111. The threaded barrel 205 is then rotated, thereby driving the contact disk 1 206 to contact the fixed disk 111 and squeeze the fixed disk 111. At this time, the squeezing force generated by the contact disk 1 206 and the fixed disk 111 can reduce the rotation of the threaded cap 110 on the threaded sleeve 109 caused by the rotating disk 201.
