Therefore, the calibration efficiency of the sensor of different types of vehicles is greatly improved.

[0060] Please refer to Figure 1 、 Figure 2 、 Figure 18 and Figure 19 In some embodiments, the display device 10 comprises a display body 11 and a connecting piece 12 arranged on the display body 11, the hanging part 10b is a clamping notch opened on the connecting piece 12, and the bracket assembly 22 comprises a hanging piece 2202, and the hanging matching part 22a is a flange formed on the hanging piece 2202.

[0061] It can be understood that the display body 11 is a display. The connecting piece 12 is a structure connected with the bracket assembly 22.

[0062] Specifically, the clamping notch is opened on the connecting piece 12, and the flange matched with the clamping notch is formed on the hanging piece 2202.

[0063] Alternatively, an opening can be arranged on the connecting piece 12, and a protruding column matched with the opening can be arranged on the hanging piece 2202.

[0064] Please refer to Figure 18 and Figure 19 In some embodiments, the bracket assembly 22 further comprises a bracket body 2201 connected with the hanging piece 2202, and the bracket body 2201 is connected with the carrier body 21.

[0065] It can be understood that the support body 2201 is a main part of the support assembly 22 and is also connected to the carrier body 21. Here, the form of the support body 2201 is not limited, for example, the support body 2201 can be a frame structure, a plate structure, and a rack structure, etc.

[0066] The hanging piece 2202 is connected to the support body 2201. Here, the connection form of the hanging piece 2202 and the support body 2201 is not limited, for example, the hanging piece 2202 can be fixedly connected to the support body 2201, that is, the two are connected by screws, welding, etc. or the hanging piece 2202 can also be movably connected to the support body 2201, that is, the two can be movably connected through the corresponding connecting piece 12, specifically, the hanging piece 2202 and the support body 2201 can be slidably connected through a slide rail and a slide block, or can also be slidably connected through a screw rod mechanism.

[0067] Please refer to Figure 18 and Figure 19 In some embodiments, the support body 2201 includes two spaced apart longitudinal beams 22011 and at least two transverse beams 22012, each transverse beam 22012 is spaced apart in the vertical direction, and the opposite ends of each transverse beam 22012 are respectively connected to the corresponding longitudinal beam 22011, the hanging piece 2202 is arranged on the two longitudinal beams 22011, and the two longitudinal beams 22011 are connected to the carrier body 21.

[0068] It can be understood that the support body 2201 is mainly formed by the two longitudinal beams 22011 and the at least two transverse beams 22012, for example, if the number of transverse beams 22012 is two, then the two longitudinal beams 22011 and the two transverse beams 22012 form a frame structure, and the weight of the support body 2201 is lighter.

[0069] Of course, in other embodiments, the number of longitudinal beams 22011 can also be increased accordingly, for example, an additional longitudinal beam 22011 is added, and the longitudinal beam 22011 is arranged between the two transverse beams 22012 for supporting the two transverse beams 22012, thereby improving the structural strength of the support body 2201.

[0070] In addition, the connection form of the two longitudinal beams 22011 and the carrier body 21 includes but is not limited to insertion, clamping, threaded connection, and welding, etc.

[0071] In this way, the support body 2201 is formed by the longitudinal beams 22011 and the transverse beams 22012, and the overall structure is simple and the weight is lighter, which is easy to assemble.

[0072] Please refer to Figure 18In some embodiments, the support assembly 22 comprises a locking member 2203, which is arranged in the longitudinal beam 22011 and connected to the connecting member 12.

[0073] It can be understood that the locking member 2203 can be in the form of a bolt, a screw, a threaded connecting member 12, or the like.

[0074] In use, the locking member 2203 is rotated to form a connection between the support body 2201 and the connecting member 12.

[0075] In this way, the display body 11 is locked and fixed by the locking member 2203, so as to improve the connection stability of the display body 11 on the support assembly 22.

[0076] Please refer to Figure 2 In some embodiments, the carrier body 21 comprises:

[0077] The horizontal distance adjusting mechanism 100 comprises a base 101, a horizontal guide mechanism 102 arranged on the base 101, and a support structure 103 fixedly connected to the horizontal guide mechanism 102, the support structure 103 being slidable along the horizontal direction through the horizontal guide mechanism 102;

[0078] The vertical distance adjusting mechanism 200 comprises a support frame 201 fixed to the support structure 103, a power part 202 arranged on the support frame 201, a first lead screw assembly 203 connected to the power part 202, and a rocker member 204 rotationally connected to the support frame 201; the first lead screw assembly 203 comprises a first lead screw body 205 having one end connected to an output end of the power part 202 and the other end rotationally connected to the support frame 201, and a first nut part 206 sleeved on the first lead screw body 205, and the rocker member 204 is engagedly connected to the first lead screw body 205;

[0079] The angle adjusting mechanism 300 comprises a fixed assembly 301 fixedly connected to the first nut part 206, a rotating shaft member 302 rotationally connected to the fixed assembly 301, an installation assembly 303 connected to the rotating shaft member 302 and capable of rotating about an axis of the rotating shaft member 302, and an adjusting rod 304 arranged on the fixed assembly 301 and capable of abutting against the installation assembly 303, and the adjusting rod 304 drives a long side or a short side of the installation assembly 303 to rotate about the axis of the rotating shaft member 302 by abutting against the installation assembly 303.

[0080] The two longitudinal beams 22011 are connected to the installation assembly 303.

[0081] It can be understood that the horizontal distance adjusting mechanism 100 comprises a base 101, a horizontal guide mechanism 102 and a support structure 103, the support structure 103 can move in the horizontal direction under the guidance of the horizontal guide mechanism 102, so as to realize the distance adjustment of the support body 2201 in the horizontal direction; the vertical distance adjusting mechanism 200 comprises a support frame 201, a power part 202, a first screw rod assembly 203 and a rocker 204; the first screw rod assembly 203 comprises a first screw rod body 205 and a first nut part 206. Here, the support frame 201 is installed on the support structure 103, so that the entire vertical distance adjusting mechanism 200 can move in the horizontal direction, at the same time, the power part 202 outputs power to drive the first screw rod body 205 of the first screw rod assembly 203 to rotate around the shaft, and finally realizes the movement of the first nut part 206 in the vertical direction, that is, realizes the distance adjustment of the support body 2201 in the vertical direction. In addition to the electric mode to realize the lifting of the first nut part 206, the rotation of the rocker 204 can also realize the rotation of the first screw rod body 205 around the shaft. The angle adjusting mechanism 300 comprises a fixed assembly 301, a rotating shaft 302, a mounting assembly 303 and an adjusting rod 304. The mounting assembly 303 can rotate around the axis of the rotating shaft in the long edge direction or the short edge direction of the fixed assembly 301, so that the two longitudinal beams 22011 arranged on the mounting assembly 303 rotate around the shaft together with the mounting assembly 303, and the entire angle adjusting process is realized by pushing or pushing the mounting assembly 303 to rotate around the shaft through the adjusting rod 304, so as to realize the control of the rotating angle of the mounting assembly 303 around the shaft, and further improve the precision of the rotation of the two longitudinal beams 22011 around the shaft. In summary, the calibration device of the present application can realize the distance adjustment of the support body 2201 in the horizontal direction and the vertical direction, and can also realize the angle adjustment of the two longitudinal beams 22011 around the rotating shaft 302, so as to improve the calibration efficiency of the calibration device, that is, the display body 11 can be adjusted in space to adapt to the use requirements of different types of vehicles.

[0082] Please refer to Figures 3 to 7In one embodiment, the base 101 comprises two beams 2201 2104 which are parallel and spaced apart. Here, the two beams 2201 2104 are used to limit the space for the horizontal sliding of the support body 2201, i.e. the support body 2201 slides horizontally between the two beams 2201 2104. The horizontal guiding mechanism 102 comprises guiding portions 106 provided on the corresponding beams 2201 2104 and sliding block portions 107 connected to the guiding portions 106. It can be understood that the guiding direction of the guiding portions 106 is parallel to the extension direction of the beams 2201 2104, and the sliding block portions 107 slide under the guiding action of the guiding portions 106, thereby regulating the moving direction of the support body 2201 and improving the distance adjustment accuracy. The support structure 103 comprises a support plate body 108 and support arms 109 provided at opposite ends of the support plate body 108, and the support plate body 108 is connected to the sliding block portions 107 through the support arms 109. Among them, the support plate body 108 is used to fix the support frame 201 of the vertical distance adjustment mechanism 200, and the support arms 109 are connected to the sliding block portions 107 and slide together with the sliding block portions 107. Finally, the support frame 201 moves with the support plate body 108 under the guiding action of the guiding portions 106. In this way, the support frame 201 mounted on the support plate body 108 slides on the guiding portions 106 through the sliding block portions 107, thereby changing the horizontal displacement of the support frame 201, and the sliding direction of the sliding block portions 107 can be regulated through the limiting of the guiding portions 106, thereby improving the distance adjustment accuracy of the support plate body 108 in the horizontal plane.

[0083] Please refer to Figures 3 to 7 In one embodiment, the support arm 109 comprises a first support sub-arm 110 and a second support sub-arm 111. Among them, the cross section of the first support sub-arm 110 is L-shaped, and the first support sub-arm 110 comprises a vertical section 112 and a horizontal section 113 perpendicular to the vertical section 112, the vertical section 112 is connected to the sliding block portion 107, and the support plate body 108 is placed on the horizontal section 113. It can be understood that the mounting end surface of the support plate body 108 is lower than the upper end surface of the beams 2201 2104, i.e. the support body 2201 is sunken between the two beams 2201 2104, so as to reduce the probability of shaking of the support frame 201 during horizontal movement due to excessive height.

[0084] The second support sub-arm 111 is connected to the vertical section 112. In this way, the cross section of the support arm 109 forms a Z shape, i.e. the first support sub-arm 110 can be connected to the sliding block portion 107, or can be connected to the sliding block portion 107 through the second support sub-arm 111.

[0085] Please refer to Figures 3 to 7In one embodiment, the horizontal distance adjusting mechanism 100 further comprises a locking member 114, which is arranged in the second support sub-arm 111 and abuts against the guide portion 106. It can be understood that when the horizontal moving distance of the support frame 201 is determined, in order to prevent it from moving, the horizontal distance adjusting mechanism 100 is additionally provided with a locking member 114, which is arranged in the second support sub-arm 111 and abuts against the guide portion 106, and the interaction between the locking member 114 and the guide portion 106 is used to achieve that the support structure 103 is stably kept stationary with the cross beam 2201 2104.

[0086] For example, the locking member 114 can be a screw or the like structure, which abuts against the guide portion 106 by screwing, so as to achieve the purpose of keeping stationary with the cross beam 2201 2104. Alternatively, the locking member 114 can also be a positioning column or the like structure, and a plurality of positioning holes are formed in the guide portion 106, and the positioning column is abutted in the corresponding positioning hole to achieve the requirement of stability.

[0087] Specifically, as shown in Figure 4 the locking member 114 comprises a locking rod 115 arranged in the second support sub-arm 111 and a knob 116 arranged on the locking rod 115. It can be understood that in the present embodiment, the locking rod 115 is provided with external threads, and the inner wall of the corresponding through hole in the second support sub-arm 111 is provided with internal threads matched with the external threads, so that the operator drives the locking rod 115 to rotate around the shaft by screwing the knob 116, thereby achieving the abutting action on the guide portion 106.

[0088] Further, in one embodiment, the guide portion 106 is provided with a positioning structure matched with the locking rod 115. It can be understood that when the friction between the end of the locking rod 115 and the surface of the guide portion 106 is insufficient or difficult to achieve that the support structure 103 is stably kept stationary with the cross beam 2201 2104, the locking rod 115 can be inserted into the positioning structure to improve the stability of the connection between the two.

[0089] Specifically, the positioning structure is a plurality of blind holes arranged on the guide portion 106 along the sliding direction. It can be understood that the gap between the blind holes can be adjusted according to actual conditions. For example, the distance between the blind holes can be equally spaced, i.e. the distance between the blind holes is linear, and then the position of the support body 2201 is equally spaced; or the distance between the blind holes can be unequal, i.e. the distance between the blind holes is nonlinear, and then the position of the support body 2201 is non-equally spaced.

[0090] Alternatively, the positioning structure is a groove formed on the guide portion 106 along the sliding direction, and a plurality of blind holes are arranged on the inner wall of the groove, each blind hole being arranged at equal intervals or non-equal intervals in the groove. In this way, when the locking rod 115 slides in the groove, the locking rod 115 is prevented from being deviated, and the locking rod 115 is locked and positioned through the corresponding blind hole.

[0091] For reference Figures 3 to 7 In an embodiment, the guide portion 106 includes a mounting plate 117 connected to the cross beam 22012104, a guide block 118 protruding outwardly from the mounting plate 117, and an anti-disengagement structure 119 arranged on the guide block 118, and the sliding block portion 107 is provided with a first groove structure 121 matched with the anti-disengagement structure 119. It can be understood that the mounting plate 117 serves as a fixed support, and the mounting plate 117 can be mounted on the cross beam 22012104 by screws or other fasteners. The guide block 118 is in direct contact with the sliding block portion 107, that is, the sliding block portion 107 moves along the sliding direction under the guidance of the guide block 118. The anti-disengagement structure 119 is used to prevent the sliding block portion 107 from disengaging along the direction perpendicular to the sliding direction, that is, to prevent the sliding block portion 107 from disengaging from between the two cross beams 22012104, thereby improving the stability of the sliding block portion 107 sliding on the guide block 118.

[0092] For example, as shown in Figure 4 and Figure 5 The anti-disengagement structure 119 is a convex rib with an arc-shaped cross section, and the sliding block portion 107 is provided with a first groove structure 121 matched with the convex rib, that is, the cross-sectional structure of the first groove structure 121 is matched with the anti-disengagement structure 119. During installation, the sliding block portion 107 is inserted into the guide block 118 from the sliding direction, so that the anti-disengagement structure 119 is inserted into the first groove structure 121. Of course, the cross-sectional shape of the anti-disengagement structure 119 can be adjusted according to actual use requirements, for example, the cross section of the anti-disengagement structure 119 can be an arrowhead shape, a rectangular shape, etc.

[0093] For reference Figures 3 to 7 In an embodiment, the guide block 118 has a first guide slope 120, the sliding block portion 107 is provided with a second groove structure 122 communicating with the first groove structure 121, the guide block 118 is accommodated in the second groove structure 122, and the second groove structure 122 has a second guide slope 123 abutting against the first guide slope 120. It can be understood that the second guide slope 123 of the sliding block portion 107 abuts against the first guide slope 120 during sliding, thereby distributing part of the gravity on the guide portion 106, and preventing the anti-disengagement structure 119 from bearing excessive gravity.

[0094] For example, the guide block 118 has two first guide slopes 120 arranged oppositely, and the second groove structure 122 has two second guide slopes 123 corresponding to the first guide slopes 120. That is, during the sliding process, the two second guide slopes 123 of the slider 107 interact with the two first guide slopes 120 of the guide block 118.

[0095] Referring to Figure 3 In an embodiment, the base 101 further comprises two vertical beams 105 for limiting the distance between the two horizontal beams 220 12104, and opposite ends of each vertical beam 105 are connected to the corresponding horizontal beam 220 12104. Here, the vertical beam 105 plays a role of fixation, so that the base 101 becomes a stable structure.

[0096] Referring to 3, in an embodiment, the horizontal distance adjusting mechanism 100 comprises support rollers 124 arranged on the horizontal beams 220 12104. Understandably, the base 101 can move on the platform with the aid of the support rollers 124. Optionally, the number of support rollers 124 is four, and one support roller 124 is arranged on each opposite end of each horizontal beam 220 12104.

[0097] Specifically, the support roller 124 comprises a roller body, a support part hinged to the roller body, and a fastening part connected to the support part, and the support part is connected to the horizontal beam 220 12104 through the fastening part. For example, the support part has a clamping groove, and the roller body is hinged to the clamping groove through a rotating shaft, and the support part has a mounting end face, and the fastening part passes through the horizontal beam 220 12104 and is connected to the mounting end face of the support part. In addition, the support roller 124 further comprises a locking structure for preventing the roller body from rotating in the clamping groove, which plays a role of limiting. It should be noted that the support roller 124 can also be a commercially available roller.

[0098] Referring to Figures 8 to 12 The support frame 201 has a bottom end part 208 and a top end part 209 arranged oppositely to the bottom end part 208. Understandably, the support frame 201 plays a role of support and is in an upright state during use. Specifically, the bottom end part 208 of the support frame 201 is in contact with the support platform, and the top end part 209 is away from the support platform, so that the angle adjusting mechanism 300 can move back and forth between the bottom end part 208 and the top end part 209.

[0099] The power part 202 is arranged at the bottom end part 208. Understandably, the power part 202 realizes power output, for example, the power part 202 can be a motor. Specifically, the motor can be started and stopped through a switch, so that the operator only needs to turn on or off the switch to realize the back-and-forth movement of the angle adjusting mechanism 300 between the bottom end part 208 and the top end part 209.

[0100] The first screw rod assembly 203 comprises a first screw rod body 205 connected to the output end of the power unit 202 at one end and rotatably connected to the top end portion 209 at the other end, and a first nut portion 206 sleeved on the first screw rod body 205, the first nut portion 206 being used for connecting the angle adjusting mechanism 300. It can be understood that the first screw rod body 205 rotates around the shaft under the driving of the power unit 202, while the first nut portion 206 cooperating with the first screw rod body 205 does not rotate around the shaft with the first screw rod body 205 due to the limiting of the angle adjusting mechanism 300, but moves along the axial direction of the first screw rod body 205, i.e. the rotational motion of the power unit 202 is converted into the linear motion of the first nut portion 206. Specifically, the first nut portion 206 is a nut structure with internal threads, for example, a threaded channel can be formed on a sliding block, and the threaded channel is engaged with the external threads of the first screw rod body 205. Meanwhile, one end of the first screw rod body 205 can be connected to the output end of the power unit 202 through a shaft coupling.

[0101] The rocker member 204 is rotatably connected to the support frame 201 and engaged with the first screw rod body 205. It can be understood that when the rocker member 204 rotates around the shaft, it is engaged with the first screw rod body 205, thereby driving the first screw rod body 205 to rotate around the shaft to drive the first nut portion 206 to move on the first screw rod body 205. The rocker member 204 is manually operated by an operator.

[0102] In summary, the vertical distance adjusting mechanism 200 has both manual and automatic modes to realize the movement of the support body 2201 in the vertical direction, and accordingly, the corresponding driving mode can be selected according to different scenes, thereby improving the distance adjusting efficiency.

[0103] Please refer to Figures 8 to 12 In one embodiment, the first screw rod assembly 203 comprises two fixed frames 207 each arranged on the support frame 201, one of the fixed frames 207 being close to the top end portion 209 and the other fixed frame 207 being close to the bottom end portion 208, and the opposite ends of the first screw rod body 205 are rotatably connected to the corresponding fixed frames 207. Here, the fixed frames 207 support the first screw rod body 205. Alternatively, bearings are arranged on the fixed frames 207, and the opposite ends of the first screw rod body 205 are connected to the corresponding bearings, so that the first screw rod body 205 rotates around the shaft between the two fixed frames 207.

[0104] Please refer to Figure 8In one embodiment, the vertical distance adjusting mechanism 200 further comprises two guide rails 210 symmetrically arranged on the support frame 201 with the central axis of the first screw body 205 as the center of symmetry, and the extension direction of each guide rail 210 is the same as the extension direction of the first screw body 205. It can be understood that the function of the two guide rails 210 is to limit the moving direction of the angle adjusting mechanism 300, that is, under the driving of the first nut part 206, the support body 2201 slides on the two guide rails 210, and at the same time, the guide rail 210 also limits the rotation of the angle adjusting mechanism 300 around the shaft, so as to ensure that the first nut part 206 always moves in the axial direction of the first screw body 205.

[0105] Please refer to Figure 8 In one embodiment, the vertical distance adjusting mechanism 200 further comprises an up-limit switch 211 and a down-limit switch 212, both of which are electrically connected with the power part 202. The up-limit switch 211 is arranged on the support frame 201 and close to the top end part 209, and the down-limit switch 212 is arranged on the support frame 201 and close to the bottom end part 208. It can be understood that the up-limit switch 211 is used to limit the upper limit position of the movement of the angle adjusting mechanism 300, and the down-limit switch 212 is used to limit the lower limit position of the movement of the angle adjusting mechanism 300. Specifically, when the first nut part 206 or the angle adjusting mechanism 300 triggers the up-limit switch 211 or the down-limit switch 212, the power part 202 stops power output, thereby avoiding the first nut part 206 or the angle adjusting mechanism 300 from being out of place.

[0106] For example, as shown in Figure 8 the up-limit switch 211 is arranged on the support frame 201 and adjacent to the fixed frame 207 at the top end part 209, and the down-limit switch 212 is arranged on the support frame 201 and adjacent to the fixed frame 207 at the bottom end part 208. It can be understood that when the first nut part 206 moves close to the fixed frame 207, the corresponding limit switch at the position is triggered, thereby avoiding the first nut part 206 from colliding with the fixed frame 207.

[0107] Please refer to Figure 8 In one embodiment, the vertical distance adjusting mechanism 200 further comprises a lifting part 213 arranged on the support frame 201. It can be understood that the lifting part 213 is arranged to facilitate the disassembly and assembly of the entire vertical distance adjusting mechanism 200, that is, during the disassembly and assembly process, the operator can use the lifting part 213 as the force application position.

[0108] For example, as shown in Figure 8 the number of the lifting part 213 is two, and the two lifting parts 213 are symmetrically arranged on the support frame 201 with the central axis of the first screw body 205 as the center of symmetry.

[0109] Please refer to Figure 1 、 Figure 4 and Figure 5 In one embodiment, the first screw body 205 is provided with a first transmission member 214, the rocker member 204 includes a rotating wheel 215 hinged to the support frame 201 and a second transmission member 216 provided on the rotating wheel 215 and rotating with the rotating wheel 215, and the first transmission member 214 is in meshing connection with the second transmission member 216. Understandably, the first transmission member 214 and the second transmission member 216 realize power transmission, that is, when the operating personnel rotates the rotating wheel 215 to make the rotating wheel 215 rotate about the shaft relative to the support frame 201, power is transmitted to the second transmission member 216, and then transmitted to the first transmission member 214 and finally drives the first screw body 205 to rotate about the shaft.

[0110] For example, the first transmission member 214 and the second transmission member 216 change the transmission direction of the force in the process of force transmission. Specifically, the first transmission member 214 rotates about the shaft in the vertical direction with the first screw body 205; and the second transmission member 216 can also be selected to rotate about the shaft in the vertical direction, that is, at this time, the rotating plane of the rotating wheel 215 is perpendicular to the axial direction of the first screw body 205. Understandably, the rotating wheel 215 is arranged along the axial direction of the first screw body 205, and at this time, the support frame 201 is suitable for being used in the case that the height is low and the weight of the support body 2201 is light.

[0111] Alternatively, the second transmission member 216 can be selected to rotate about the shaft in the horizontal direction, that is, at this time, the rotating plane of the rotating wheel 215 is parallel to the axial direction of the first screw body 205. Understandably, the rotating wheel 215 is arranged on one side of the first screw body 205, and at this time, the support body 2201 is suitable for being used in the case that the weight is heavy. Of course, the rotating mode of the second transmission member 216 about the shaft can be selected according to the actual scene.

[0112] Specifically, in one embodiment, the first transmission member 214 is a worm gear, and the second transmission member 216 is a worm. Understandably, the worm gear and the worm are matched with each other to change the transmission direction of the force of the rotating wheel 215, that is, the rotating wheel 215 is arranged on one side of the first screw body 205, and the transmission torque is also larger, which is suitable for being used in the case that the weight is heavy. Of course, the positions of the worm gear and the worm can be exchanged, that is, the first transmission member 214 is a worm, and the second transmission member 216 is a worm gear.

[0113] Specifically, in another embodiment, the first transmission member 214 can also be a first bevel gear, and the second transmission member 216 can be a second bevel gear. It can be understood that the first transmission member 214 and the second transmission member 216 are both bevel gears, and the engagement characteristics of the two bevel gears are utilized to change the transmission direction of the force of the rotating wheel 215, i.e., the rotating wheel 215 is also arranged on one side of the first screw body 205.

[0114] Please refer to Figures 8 to 12 In one embodiment, the rocker member 204 further comprises a handle 217 hingedly connected to the rotating wheel 215, and the rotating wheel 215 has a receiving cavity 218, and the handle 217 can be accommodated in the receiving cavity 218. It can be understood that the handle 217 has two states: one is a use state, and the handle 217 is wound around the rotating wheel 215 and is in an unfolded state, at this time, a user can hold the handle 217 to drive the rotating wheel 215 to rotate around the shaft; the other is a non-use state, and the handle 217 is accommodated in the receiving cavity 218.

[0115] Please refer to Figures 13 to 17 In one embodiment, the fixing assembly 301 comprises a fixing housing 305, the fixing housing 305 comprises a fixing vertical plate 306 and two fixing horizontal plates 308 vertically connected to the fixing vertical plate 306, and the opposite ends of the rotating shaft member 302 are respectively rotationally connected to the corresponding fixing horizontal plates 308. It can be understood that the fixing housing 305 has a U-shaped groove structure in cross section, and the mounting assembly 303 is accommodated in the groove structure space formed by the fixing housing 305, of course, according to actual use needs, the mounting assembly 303 can be accommodated in the groove structure space in a long edge direction, or in a short edge direction. In addition, the opposite ends of the rotating shaft member 302 are respectively rotationally connected to the corresponding fixing horizontal plates 308 through bearings, i.e., the rotating shaft member 302 can rotate around the shaft between the two fixing horizontal plates 308.

[0116] Please refer to Figures 13 to 17In one embodiment, the mounting assembly 303 comprises a mounting housing 308, which comprises a mounting vertical plate 309 and two mounting horizontal plates 310 connected to the mounting vertical plate 309 perpendicularly, the opposite ends of the rotating shaft 302 are respectively arranged in the corresponding mounting horizontal plate 310, and the rotating shaft 302 is connected to the mounting vertical plate 309. It can be understood that the cross section of the mounting housing 308 also forms a U-shaped groove structure, and when mounted, the opening end of the mounting housing 308 faces the opening end of the fixed housing 305, and the two mounting horizontal plates 310 correspond to the two fixed horizontal plates 308 respectively. Optionally, the mounting horizontal plate 310 extends into the groove structure space of the fixed housing 305, and the mounting horizontal plate 310 is parallel to the fixed horizontal plate 308. At the same time, in order to obtain the rotating space, a through hole for the rotating shaft 302 to pass through is formed on the mounting horizontal plate 310. And the rotating shaft 302 can be connected to the mounting vertical plate 309 by screws and other fasteners, so as to ensure that the mounting vertical plate 309 rotates with the rotating shaft 302.

[0117] Please refer to Figures 13 to 17 Specifically, the adjusting rod 304 comprises a rod body 311 arranged in the fixed vertical plate 306 and abutting against the mounting vertical plate 309, and an adjusting handle 312 arranged on the rod body 311. It can be understood that the rod body 311 can abut against the mounting vertical plate 309 in a manner of applying force along the axial direction of the rod body 311, so as to make the mounting vertical plate 309 rotate relative to the fixed vertical plate 306. At this time, a scale can be arranged on the rod body 311, and the specific rotation angle of the mounting vertical plate 309 is determined according to the scale value. Alternatively, a threaded hole is formed on the fixed vertical plate 306, and an external thread is arranged on the rod body 311, that is, the rod body 311 is abutted against the mounting vertical plate 309 by rotating, and a scale can also be arranged on the rod body 311 to clearly indicate the specific rotation angle of the mounting vertical plate 309. And the adjusting handle 312 is convenient for the operator to apply force, for example, the adjusting handle 312 can be a knob, so as to facilitate the operator to rotate the rod body 311 by the knob.

[0118] Please refer to Figures 13 to 17In one embodiment, the angle adjusting mechanism 300 further comprises a reset rod 313, and a waist-shaped hole 314 is formed on the fixed assembly 301, one end of the reset rod 313 is connected to the mounting assembly 303 and the other end is arranged outside through the waist-shaped hole 314. It can be understood that the adjusting rod 304 pushes the mounting assembly 303 to rotate around the fixed assembly 301 by pushing, but it cannot be pulled back after being pushed out. Therefore, a reset rod 313 is added, which is preferably symmetrically arranged with the adjusting rod 304 with the central axis of the rotating shaft 302 as the symmetric center. In this way, the mounting assembly 303 after rotation can be pushed back to the reset position through the reset rod 313. At the same time, the waist-shaped hole 314 formed on the fixed assembly 301 also has the function of limiting the rotating angle of the mounting assembly 303. When the mounting assembly 303 rotates around the shaft to the limit position, the reset rod 313 is limited by the hole wall of the waist-shaped hole 314, thereby preventing the mounting assembly 303 from continuing to rotate.

[0119] For example, as shown in Figure 13 the waist-shaped hole 314 is formed on the fixed vertical plate 306 of the fixed assembly 301, and one end of the reset rod 313 is connected to the mounting vertical plate of the mounting assembly 303, thereby corresponding to the adjusting rod 304 and being distributed on both sides of the rotating shaft 302.

[0120] For example, as shown in Figure 15 In one embodiment, the mounting assembly 303 further comprises a mounting cylinder 315, which is used for the longitudinal beam 22011, and the mounting cylinder 315 is arranged on the mounting vertical plate 309. It can be understood that when the target piece has a support rod that needs to be fixed, it can be inserted into the mounting cylinder 315.

[0121] For example, two mounting cylinders 315 are symmetrically arranged on the mounting vertical plate 309, and the mounting cylinder 315 is surrounded by the mounting vertical plate 309 as a side wall to form a containing space for containing the longitudinal beam 22011. In order to tighten the support rod, a screw is further arranged on the mounting cylinder 315, which is arranged in the containing space through the mounting cylinder 315. In this way, the screw can be tightened to tighten the support rod.

[0122] For example, as shown in Figures 13 to 17 In one embodiment, the fixed assembly 301 further comprises a fixed cover 316 and a second screw rod assembly 317. Here, the fixed cover 316 is used to connect with the support body 2201, so that after being connected with the support body 2201, the fixed cover 316 is kept fixed, so that the whole fixed assembly 301 is fixed and different, and the mounting assembly 303 rotates around the axis of the rotating shaft 302 relative to the fixed assembly 301 under the pushing of the adjusting rod 304.

[0123] The second screw rod assembly 317 is used to adjust the horizontal displacement of the fixed vertical plate 306 relative to the fixed cover 316. The second screw rod assembly 317 comprises a second nut part 318 connected to the fixed vertical plate 306 and a second screw rod body 319 rotatably connected to the fixed cover 316. The second screw rod body 319 is arranged through the second nut part 318 and threadedly cooperates with the second nut part 318. It can be understood that the fixed housing 305 and the fixed cover 316 can move relative to each other, i.e., they are not fixedly connected. Specifically, the second nut part 318 in the second screw rod assembly 317 is mounted on the fixed vertical plate 306, and the second screw rod body 319 is rotatably connected to the fixed cover 316. When the second screw rod body 319 rotates around the shaft, the second nut part 318 converts the rotation of the second screw rod body 319 around the shaft into movement along the axial direction of the second screw rod body 319, so that the fixed vertical plate 306 can move along the axial direction of the second screw rod body 319 relative to the fixed cover 316. In this way, the support body 2201 can be fine-adjusted in the horizontal direction while obtaining the rotation angle, thereby obtaining a larger range of viewing angle.

[0124] Specifically, the second screw rod assembly 317 comprises a positioning ring 320 fixedly connected to the fixed cover 316, and the second screw rod body 319 is rotatably connected to the positioning ring 320 through a bearing. It can be understood that the positioning ring 320 plays a role of connection and bearing. Specifically, the positioning ring 320 is provided with mounting ears, and the positioning ring 320 is fixed to the fixed cover 316 through screws arranged through the mounting ears. Meanwhile, the second screw rod body 319 arranged through the positioning ring 320 rotates in the positioning ring 320.

[0125] For example, as shown in Figure 17 , the number of the positioning rings 320 is two, and the two positioning rings 320 are symmetrically arranged on the two sides of the second nut part 318 with the second nut part 318 as the center of symmetry. At this time, the second screw rod body 319 is arranged through one of the positioning rings 320, the second nut part 318 and the other positioning ring 320 in sequence. In this way, the second screw rod body 319 rotates between the two positioning rings 320, and the second nut part 318 moves along the axial direction of the screw nut when the second screw rod body 319 rotates around the shaft. The above-mentioned arrangement mode of the positioning ring 320 has higher stability.

[0126] For example, as shown in Figure 17 , in one embodiment, the second screw rod assembly 317 comprises a knob part 321 connected to one end of the second screw rod body 319, and the knob part 321 extends to the outside of the fixed cover 316. It can be understood that the knob part 321 can increase the force point of the operator on the second screw rod body 319, and it is more convenient to rotate the second screw rod body 319.

[0127] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
