[0053] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides a calibration device, including a display device 10 and a carrier mechanism 20.

[0054] It can be understood that the display device 10 is used to display and switch the corresponding target identification. The target identification here is an electronic target in the form of an image. The carrier mechanism 20 is used to support the display device 10 so that the display device 10 meets the setting requirements of a certain height and angle.

[0055] The display device 10 includes a display portion 10 a and a card hanging portion 10 b facing the display portion 10 a .

[0056] Here, the display part 10a is mainly a display screen, which is a carrier for realizing the electronic target to appear in the form of an image. The hanging card part 10b is used to connect with the carrier mechanism 20 to meet the needs of rapid disassembly and assembly.

[0057] The carrier mechanism 20 includes a carrier body 21 and a bracket assembly 22 connected to the carrier body 21 . The bracket assembly 22 has a hanging card matching portion 22 a adapted to the hanging card portion 10 b .

[0058] Here, the carrier body 21 is the main body of the carrier mechanism 20, and the bracket assembly 22 is for the display screen hanging card portion 10b.

[0059] The calibration device provided by the embodiment of the present invention uses the display part 10a of the display device 10 to display the corresponding electronic target, which can meet the calibration requirements of the installation position of sensors of different types of vehicles. At the same time, the hanging card part 10b can be quickly disassembled and assembled to the hanging card matching part 22a of the bracket assembly 22 of the carrier mechanism 20, that is, the electronic target can be switched to a conventional physical target. In this way, the calibration efficiency of sensors of different types of vehicles is greatly improved.

[0060] Please refer to Figure 1 , Figure 2 , Fig.18 and Fig.19 In some embodiments, the display device 10 includes a display body 11 and a connecting member 12 provided on the display body 11, the hanging card portion 10b is a clamping notch opened on the connecting member 12, the bracket assembly 22 includes a hanging card member 2202, and the hanging card matching portion 22a is a flange formed on the hanging card member 2202.

[0061] It can be understood that the display body 11 is a display, and the connecting member 12 is a structure connected to the bracket assembly 22 .

[0062] Specifically, a clamping notch is provided on the connecting member 12 , and a flange matched with the clamping notch is formed on the hanging clamp member 2202 .

[0063] Alternatively, an opening may be provided on the connecting member 12 , and a protruding column adapted to the opening may be provided on the hanging clamp 2202 .

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

[0065] It can be understood that the support body 2201 is the main part of the support assembly 22 and is also the part connected to the carrier body 21. Here, the structural 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.

[0066] The hanging clamp 2202 is connected to the bracket body 2201. Here, the connection form between the hanging clamp 2202 and the bracket body 2201 is not limited. For example, the hanging clamp 2202 can be fixedly connected to the bracket body 2201, that is, the two are connected by screws, welding, etc.; or, the hanging clamp 2202 can also be movably connected to the bracket body 2201, that is, the two can be movably connected through the corresponding connecting member 12. Specifically, the hanging clamp 2202 and the bracket body 2201 can be slidably connected through a slide rail and a slider, or can also be slidably connected through a screw mechanism.

[0067] Please refer to Fig.18 and Fig.19 In some embodiments, the bracket body 2201 includes two longitudinal beams 22011 and at least two transverse beams 22012 that are spaced apart from each other. The transverse beams 22012 are spaced apart from each other in the vertical direction, and the opposite ends of each transverse beam 22012 are respectively connected to the corresponding longitudinal beams 22011. The hanging card 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 two longitudinal beams 22011 and at least two cross beams 22012. For example, if there are two cross beams 22012, then the two longitudinal beams 22011 and the two cross beams 22012 form a frame structure, and then the weight of the support body 2201 is lighter.

[0069] Of course, in other embodiments, the number of longitudinal beams 22011 may also be increased accordingly. For example, an additional longitudinal beam 22011 is added, and the longitudinal beam 22011 is set between two cross beams 22012 to support the two cross beams 22012, thereby improving the structural strength of the bracket body 2201.

[0070] Furthermore, the connection forms between the two longitudinal beams 22011 and the carrier body 21 include but are not limited to plug-in, snap-on, threaded connection, and welding.

[0071] In this way, the bracket body 2201 is surrounded by the longitudinal beam 22011 and the transverse beam 22012, and its overall structure is simple, lighter, and easy to assemble.

[0072] Please refer to Fig.18In some embodiments, the bracket assembly 22 includes a locking member 2203 , which is passed through the longitudinal beam 22011 and connected to the connecting member 12 .

[0073] It can be understood that the structural form of the locking member 2203 includes but is not limited to connecting members 12 such as bolts, screws, and threaded connecting members 12.

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

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

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

[0077] The horizontal distance adjustment mechanism 100 includes a base 101, a horizontal guide mechanism 102 disposed on the base 101, and a support structure 103 fixedly connected to the horizontal guide mechanism 102, and the support structure 103 slides in the horizontal direction through the horizontal guide mechanism 102;

[0078] The vertical pitch adjustment mechanism 200 includes a support frame 201 fixed on the support structure 103, a power unit 202 arranged on the support frame 201, a first screw assembly 203 connected to the power unit 202, and a rocker 204 rotatably connected to the support frame 201; the first screw assembly 203 includes a first screw body 205 connected to the output end of the power unit 202 at one end and rotatably connected to the support frame 201 at the other end, and a first nut portion 206 sleeved on the first screw body 205, and the rocker 204 is meshedly connected to the first screw body 205;

[0079] The angle adjustment mechanism 300 includes a fixing assembly 301 fixedly connected to the first nut portion 206, a rotating shaft 302 rotatably connected to the fixing assembly 301, a mounting assembly 303 connected to the rotating shaft 302 and capable of rotating around the axis of the rotating shaft 302, and an adjusting rod 304 disposed on the fixing assembly 301 and capable of pushing against the mounting assembly 303, and the adjusting rod 304 drives the long side or short side of the mounting assembly 303 to rotate around the axis of the rotating shaft 302 by pushing against the fixing assembly 301.

[0080] Among them, the two longitudinal beams 22011 are connected to the mounting assembly 303 .

[0081] It can be understood that the horizontal distance adjustment mechanism 100 includes 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 to adjust the distance of the bracket body 2201 in the horizontal direction. The vertical distance adjustment mechanism 200 includes a support frame 201, a power unit 202, a first screw assembly 203 and a rocker 204. The first screw assembly 203 includes a first screw 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 adjustment mechanism 200 can move in the horizontal direction. At the same time, the power unit 202 outputs power to drive the first screw body 205 of the first screw assembly 203 to rotate around the axis, and finally, the first nut part 206 is moved in the vertical direction, that is, the distance adjustment of the bracket body 2201 in the vertical direction is achieved. In addition, in addition to achieving the lifting and lowering of the first nut portion 206 by electric means, the first screw body 205 can also be rotated around the axis by rotating the rocker member 204. The angle adjustment mechanism 300 includes a fixed component 301, a rotating shaft member 302, a mounting component 303 and an adjusting rod 304. The mounting component 303 can rotate around the axis of the rotating shaft in the long side direction or the short side direction relative to the fixed component 301, so that the two longitudinal beams 22011 arranged on the mounting component 303 rotate around the axis with the mounting component 303, and the entire angle adjustment process is achieved by pushing or toggling the mounting component 303 by the adjusting rod 304 to achieve the rotation around the axis, so that the rotation angle of the mounting component 303 around the axis is controlled, thereby improving the accuracy of the rotation of the two longitudinal beams 22011 around the axis. In summary, the calibration device of the present application can realize the distance adjustment of the bracket body 2201 in the horizontal direction and the vertical direction. At the same time, it can also realize the angle adjustment of the two longitudinal beams 22011 around the rotating shaft 302, thereby improving the calibration efficiency of the calibration device, that is, the display body 11 can be adjusted in position in space to adapt to the use requirements of different types of vehicle models.

[0082] Please refer to Figures 3 to 7In one embodiment, the base 101 includes two beams 22012104 that are parallel to each other and spaced apart. Here, the two beams 22012104 are used to limit the horizontal sliding space of the bracket body 2201, that is, the bracket body 2201 slides horizontally between the two beams 22012104. The horizontal guide mechanism 102 includes a guide portion 106 provided on the corresponding beam 22012104 and a slider portion 107 slidably connected to the guide portion 106. It can be understood that the guiding direction of the guide portion 106 is parallel to the extension direction of the beam 22012104, and the slider portion 107 slides under the guiding action of the guide portion 106, thereby regulating the moving position of the bracket body 2201 and improving the distance adjustment accuracy. The support structure 103 includes 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 slider portion 107 through the support arms 109. The support plate body 108 is used to fix the support frame 201 of the vertical distance adjustment mechanism 200, and the support arm 109 is connected to the slider 107 and slides with the slider 107. Finally, the support frame 201 moves with the support plate body 108 under the guidance of the guide 106. In this way, the support frame 201 installed on the support plate body 108 slides on the guide 106 through the slider 107, thereby changing the horizontal displacement of the support frame 201, and the sliding direction of the slider 107 can be regulated by the limit of the guide 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 includes a first support sub-arm 110 and a second support sub-arm 111. The cross section of the first support sub-arm 110 is L-shaped, and the first support sub-arm 110 includes a vertical section 112 and a horizontal section 113 perpendicular to the vertical section 112. The vertical section 112 is connected to the slider 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 cross beam 22012104, that is, the bracket body 2201 is sunk between the two cross beams 22012104, so as to reduce the probability of the support frame 201 shaking during horizontal movement due to excessive height.

[0084] The second supporting sub-arm 111 is connected to the vertical section 112. Thus, the cross section of the supporting arm 109 is formed into a Z shape, that is, the first supporting sub-arm 110 can be connected to the slider portion 107, and can also be connected to the slider portion 107 through the second supporting sub-arm 111.

[0085] Please refer to Figures 3 to 7In one embodiment, the horizontal distance adjustment mechanism 100 further includes a locking member 114, which is disposed through the second supporting sub-arm 111 and abuts against the guide portion 106. It can be understood that when the horizontal movement distance of the support frame 201 is determined, in order to prevent it from moving, the horizontal distance adjustment mechanism 100 is additionally provided with a locking member 114, which is disposed through the second supporting 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 the support structure 103 being stably kept stationary with the crossbeam 22012104.

[0086] For example, the locking member 114 can be a structure such as a screw, which is screwed to abut against the guide portion 106, thereby achieving the purpose of keeping the crossbeam 22012104 still. Alternatively, the locking member 114 can also be a structure such as a positioning column, and a plurality of positioning holes are provided on the guide portion 106, and the stability requirement is achieved by abutting the positioning columns against the corresponding positioning holes.

[0087] Specifically, Figure 4 As shown, the locking member 114 includes a locking rod 115 that penetrates the second supporting sub-arm 111 and a knob 116 that is disposed on the locking rod 115. It can be understood that in this embodiment, an external thread is provided on the locking rod 115, and at the same time, an internal thread that matches the external thread is provided on the inner wall of the corresponding through hole on the second supporting sub-arm 111, so that the operator drives the locking rod 115 to rotate around the axis by turning the knob 116, thereby realizing the abutment effect on the guide portion 106.

[0088] Furthermore, in one embodiment, a positioning structure adapted to the locking rod 115 is provided on the guide portion 106. 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 and the crossbeam 22012104 remain stationary stably, 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 at intervals along the sliding direction. It can be understood that the gaps between the blind holes can be adjusted according to actual conditions. For example, the spacing between the blind holes can be arranged at equal intervals, that is, the spacing between the blind holes is linear, then the positions where the bracket body 2201 is limited are equidistant; or, the spacing between the blind holes can be unequal, that is, the spacing between the blind holes is non-linear, then the positions where the bracket body 2201 is limited are non-equidistant.

[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 formed on the inner wall of the groove, and the blind holes are arranged at equal intervals or at 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 at the same time, the locking rod 115 is locked and limited by the corresponding blind holes.

[0091] Please refer to Figures 3 to 7 In one embodiment, the guide portion 106 includes a mounting plate 117 connected to the cross beam 22012104, a guide block 118 formed by the mounting plate 117 protruding outward, and an anti-slip structure 119 provided on the guide block 118, and a first groove structure 121 adapted to the anti-slip structure 119 is provided on the slider portion 107. It can be understood that the mounting plate 117 plays a fixed supporting role. Optionally, the mounting plate 117 can be installed on the cross beam 22012104 by fasteners such as screws. At the same time, the guide block 118 is in direct contact with the slider portion 107, that is, the slider portion 107 moves along the sliding direction under the guidance of the guide block 118. And the anti-slip structure 119 is used to prevent the slider portion 107 from slipping out in a direction perpendicular to the sliding direction, that is, to prevent the slider portion 107 from slipping out from between the two cross beams 22012104, thereby improving the stability of the slider portion 107 sliding on the guide block 118.

[0092] For example, Figure 4 and Figure 5 As shown, the anti-slip structure 119 is a convex rib with an arc-shaped cross section. At the same time, the slider 107 is provided with a first groove structure 121 adapted to the convex rib, that is, the cross-sectional structure of the first groove structure 121 is adapted to the anti-slip structure 119. During installation, the slider 107 is inserted into the guide block 118 from the sliding direction, so that the anti-slip structure 119 is slidably inserted into the first groove structure 121. Of course, the cross-sectional shape of the anti-slip structure 119 can be adjusted according to actual use requirements. For example, the cross-sectional shape of the anti-slip structure 119 can be arrow-shaped, rectangular, etc.

[0093] Please refer to Figures 3 to 7 In one embodiment, the guide block 118 has a first guide slope 120, and the slider 107 is provided with a second groove structure 122 connected to 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 slider 107 abuts against the first guide slope 120 during the sliding process, thereby distributing part of the gravity to the stop guide portion 106, and preventing the anti-slip structure 119 from bearing too much gravity.

[0094] For example, the guide block 118 has two first guide slopes 120 arranged opposite to each other, and similarly, 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 portion 107 interact with the two first guide slopes 120 of the guide block 118.

[0095] Please refer to Figure 3 In one embodiment, the base 101 further includes two vertical beams 105 for limiting the distance between the two horizontal beams 22012104, and the opposite ends of each vertical beam 105 are respectively connected to the corresponding horizontal beam 22012104. Here, the vertical beams 105 play a fixing role, making the base 101 a stable structure.

[0096] Please refer to 3. In one embodiment, the horizontal distance adjustment mechanism 100 includes a support roller 124, and the support roller 124 is disposed on the crossbeam 22012104. It can be understood that the base 101 can move on the platform with the assistance of the support roller 124. Optionally, the number of the support roller 124 is four, and a support roller 124 is disposed at each of the opposite ends of each crossbeam 22012104.

[0097] Specifically, the support roller 124 includes a roller body, a support portion hinged to the roller body, and a fastening portion connected to the support portion, and the support portion is connected to the crossbeam 22012104 through the fastening portion. For example, the support portion has a clamping groove, the roller body is hinged in the clamping groove through a rotating shaft, and the support portion has a mounting end face, and the fastening portion passes through the crossbeam 22012104 and is connected to the mounting end face of the support portion. In addition, the support roller 124 also includes a locking structure, which is used to prevent the roller body from rotating in the clamping groove and plays a role of limiting. It should be noted that the support roller 124 can also be a commercially available roller.

[0098] Please refer to Figures 8 to 12 The support frame 201 has a bottom end 208 and a top end 209 disposed opposite to the bottom end 208. It can be understood that the support frame 201 plays a supporting role and is in an upright state when in use. Specifically, the bottom end 208 of the support frame 201 is in contact with the support platform, while the top end 209 is away from the support platform, so that the angle adjustment mechanism 300 can reciprocate between the bottom end 208 and the top end 209.

[0099] The power unit 202 is disposed at the bottom end 208. It can be understood that the power unit 202 realizes power output, for example, the power unit 202 can be a motor. Specifically, the motor can be started and stopped by a switch, so that the operator can realize the reciprocating movement of the angle adjustment mechanism 300 between the bottom end 208 and the top end 209 by simply turning on or off the switch.

[0100] The first screw assembly 203 includes a first screw body 205, one end of which is connected to the output end of the power unit 202 and the other end is rotatably connected to the top end 209, and a first nut part 206 sleeved on the first screw body 205, and the first nut part 206 is used to connect the angle adjustment mechanism 300. It can be understood that the first screw body 205 rotates around the axis driven by the power unit 202. At the same time, the first nut part 206 matched with the first screw body 205 does not rotate around the axis with the first screw body 205 due to the limitation of the angle adjustment mechanism 300, but moves along the axial direction of the first screw body 205, that is, the rotational motion of the power unit 202 is converted into the linear motion of the first nut part 206. Specifically, the first nut part 206 is a nut structure with an internal thread. For example, a threaded channel can be opened on a slider, and the threaded channel is meshed with the external thread of the first screw body 205. At the same time, one end of the first screw body 205 can be connected to the output end of the power unit 202 through a coupling.

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

[0102] In summary, the vertical distance adjustment mechanism 200 has both manual and automatic modes to realize the movement of the bracket body 2201 in the vertical direction, and then, the corresponding driving mode can be selected according to different scenarios, so as to improve the distance adjustment efficiency.

[0103] Please refer to Figures 8 to 12 In one embodiment, the first screw assembly 203 includes two fixing frames 207 both disposed on the support frame 201, wherein one fixing frame 207 is close to the top end 209, and the other fixing frame 207 is close to the bottom end 208, and the opposite ends of the first screw body 205 are rotatably connected to the corresponding fixing frames 207. Here, the fixing frames 207 support the first screw body 205. Optionally, bearings are provided on the fixing frames 207, and the opposite ends of the first screw body 205 are connected to the corresponding bearings, so that the first screw body 205 rotates around the axis between the two fixing frames 207.

[0104] Please refer to Figure 8In one embodiment, the vertical distance adjustment mechanism 200 further includes two guide rails 210, which are symmetrically arranged on the support frame 201 with the central axis of the first screw body 205 as the symmetry center, 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 two guide rails 210 function to limit the moving direction of the angle adjustment mechanism 300, that is, driven by the first nut part 206, the support body 2201 slides on the two guide rails 210, and at the same time, the guide rails 210 also have the function of limiting the rotation of the angle adjustment mechanism 300 around the axis to ensure that the first nut part 206 always moves along the axial direction of the first screw body 205.

[0105] Please refer to Figure 8 In one embodiment, the vertical distance adjustment mechanism 200 further includes an upward limit switch 211 and a downward limit switch 212 both electrically connected to the power unit 202. The upward limit switch 211 is disposed on the support frame 201 and is close to the top end 209, and the downward limit switch 212 is disposed on the support frame 201 and is close to the bottom end 208. It can be understood that the upward limit switch 211 is used to limit the upward limit position of the movement of the angle adjustment mechanism 300, and the downward limit switch 212 is used to limit the downward limit position of the movement of the angle adjustment mechanism 300. Specifically, when the first nut portion 206 or the angle adjustment mechanism 300 triggers the upward limit switch 211 or the downward limit switch 212, the power unit 202 stops the power output, thereby preventing the first nut portion 206 or the angle adjustment mechanism 300 from falling out.

[0106] For example, Figure 8 As shown, the upward limit switch 211 is arranged on the support frame 201 and is adjacent to the fixed frame 207 located at the top end 209, and the downward limit switch 212 is arranged on the support frame 201 and is adjacent to the fixed frame 207 located at the bottom end 208. It can be understood that when the first nut portion 206 moves near the fixed frame 207, the limit switch at the corresponding position is triggered, thereby preventing the first nut portion 206 from colliding with the fixed frame 207.

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

[0108] For example, Figure 8 As shown, there are two lifting portions 213 , and the two lifting portions 213 are symmetrically arranged on the support frame 201 with the central axis of the first screw rod body 205 as the symmetry center.

[0109] Please refer to Figure 1 , Figure 4 and Figure 5 In one embodiment, a first transmission member 214 is provided on the first screw body 205, and the rocker member 204 includes a rotating wheel 215 hinged on the support frame 201 and a second transmission member 216 provided on the rotating wheel 215 and rotating around the axis with the rotating wheel 215, and the first transmission member 214 is meshed and connected with the second transmission member 216. It can be understood that the first transmission member 214 and the second transmission member 216 realize the transmission of power, that is, when the operator rotates the rotating wheel 215 so that the rotating wheel 215 rotates around the axis relative to the support frame 201, the power is transmitted to the second transmission member 216, and then transmitted to the first screw body 205 by the first transmission member 214, and finally drives the first screw body 205 to rotate around the axis.

[0110] For example, the first transmission member 214 and the second transmission member 216 change the force transmission direction during the force transmission process. Specifically, the first transmission member 214 rotates around the axis together with the first screw rod body 205, and is in the state of rotating around the axis in the vertical direction; and the second transmission member 216 can also choose to rotate around the axis in the vertical direction, that is, at this time, the rotation plane of the rotating wheel 215 is perpendicular to the axial direction of the first screw rod body 205. It can be understood that the rotating wheel 215 is arranged along the axial direction of the first screw rod body 205. At the same time, in this scenario, it is suitable for use when the height of the support frame 201 is relatively low and the weight of the support body 2201 is relatively light.

[0111] Alternatively, the second transmission member 216 can be rotated in the horizontal direction around the axis, that is, at this time, the rotation plane of the rotating wheel 215 is parallel to the axial direction of the first screw body 205. It can be understood that the rotating wheel 215 is arranged on one side of the first screw body 205. At the same time, in this scenario, it is suitable for use when the weight of the bracket body 2201 is heavy. Of course, the rotation mode of the second transmission member 216 around the axis can be selected according to the actual scenario.

[0112] Specifically, in one embodiment, the first transmission member 214 is a worm wheel, and the second transmission member 216 is a worm. It can be understood that the mutual adaptation of the worm wheel and the worm changes 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 at the same time, the transmission torque is also larger, which is suitable for use in heavy weight situations. Of course, the setting positions of the worm wheel and the worm can be interchanged, that is, the first transmission member 214 is a worm, and the second transmission member 216 is a worm wheel.

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

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

[0115] Please refer to Figures 13 to 17 In one embodiment, the fixed assembly 301 includes a fixed housing 305, the fixed housing 305 includes a fixed vertical plate 306 and two fixed horizontal plates 308 vertically connected to the fixed vertical plate 306, and the opposite ends of the rotating shaft 302 are respectively rotatably connected to the corresponding fixed horizontal plates 308. It can be understood that the cross-section of the fixed housing 305 is a U-shaped groove structure, and the installation assembly 303 is accommodated in the groove structure space enclosed by the fixed housing 305. Of course, according to actual use needs, the installation assembly 303 can be selected to be accommodated in the groove structure space in the long side direction, or in the short side direction. And the opposite ends of the rotating shaft 302 are respectively rotatably connected to the corresponding fixed horizontal plates 308 through bearings, that is, the rotating shaft 302 can rotate around the axis between the two fixed horizontal plates 308.

[0116] Please refer to Figures 13 to 17In one embodiment, the mounting assembly 303 includes a mounting housing 308, the mounting housing 308 includes a mounting vertical plate 309 and two mounting horizontal plates 310 vertically connected to the mounting vertical plate 309, the opposite ends of the rotating shaft 302 are respectively penetrated through the corresponding mounting horizontal plates 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 presents a U-shaped groove structure, and when installed, the open end of the mounting housing 308 faces the open 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 a rotation space, a through hole for the rotating shaft 302 to penetrate is opened on the mounting horizontal plate 310. Furthermore, the rotating shaft member 302 can be connected to the mounting vertical plate 309 by means of fasteners such as screws, thereby ensuring that the mounting vertical plate 309 rotates together with the rotating shaft member 302 .

[0117] Please refer to Figures 13 to 17 Specifically, the adjustment rod 304 includes a rod body 311 that penetrates the fixed vertical plate 306 and pushes against the mounting vertical plate 309, and an adjustment handle 312 provided on the rod body 311. It can be understood that the rod body 311 can push against the mounting vertical plate 309 by applying a force along its axial direction, so that the mounting vertical plate 309 rotates around the fixed vertical axis. At this time, a scale can be set 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 opened on the fixed vertical plate 306, and an external thread matching the threaded hole is provided on the rod body 311, that is, the mounting vertical plate 309 is pushed against by rotating the rod body 311. Similarly, a scale can also be set on the rod body 311 to clarify the specific rotation angle of the mounting vertical plate 309. Furthermore, the adjustment handle 312 is convenient for the operator to apply force. For example, the adjustment handle 312 can be a knob, so that the operator can conveniently rotate the rod body 311 through the knob.

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

[0119] For example, Fig.13 As shown, a waist-shaped hole 314 is provided on the fixed vertical plate 306 of the fixing assembly 301 , and one end of the reset rod 313 is connected to the mounting vertical of the mounting assembly 303 , thereby corresponding to the adjustment rod 304 and distributed on both sides of the rotating shaft 302 .

[0120] Please refer to Fig.15 In one embodiment, the mounting assembly 303 further includes a mounting cylinder 315, which is used for the longitudinal beam 22011 and is disposed on the mounting vertical plate 309. It can be understood that when the target part 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 uses the mounting vertical plate 309 as a side wall to enclose a storage space for accommodating the longitudinal beam 22011. At the same time, in order to fasten the support rod, a screw is also arranged on the mounting cylinder 315. The screw passes through the mounting cylinder 315 and is placed in the storage space. In this way, the support rod can be fastened by screwing.

[0122] Please refer to Figures 13 to 17 In one embodiment, the fixing assembly 301 further includes a fixing cover 316 and a second screw assembly 317. Here, the fixing cover 316 is used to connect with the bracket body 2201. Thus, after being connected with the bracket body 2201, the fixing cover 316 remains fixed, so that the entire fixing assembly 301 is fixed, and the mounting assembly 303 rotates relative to the fixing assembly 301 around the axis of the rotating shaft 302 under the pushing action of the adjusting rod 304.

[0123] The second screw assembly 317 is used to adjust the relative horizontal displacement between the fixed vertical plate 306 and the fixed cover 316. The second screw assembly 317 includes a second nut portion 318 connected to the fixed vertical plate 306 and a second screw body 319 rotatably connected to the fixed cover 316. The second screw body 319 is inserted through the second nut portion 318 and threadedly engaged with the second nut portion 318. It can be understood that the fixed housing 305 and the fixed cover 316 can move relative to each other, that is, there is no fixed connection between the two. Specifically, the second nut portion 318 in the second screw rod assembly 317 is installed 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 axis, the second nut portion 318 converts the rotation of the second screw rod body 319 around the axis into an axial movement along 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 bracket body 2201 can obtain the rotation angle while also performing fine-tuning translation in the horizontal direction, thereby obtaining a wider range of viewing angles.

[0124] Specifically, the second screw assembly 317 includes a positioning ring 320 fixedly connected to the fixed cover 316, and the second screw 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 a mounting ear, and the positioning ring 320 is fixed to the fixed cover 316 by screws passing through the mounting ears. At the same time, the second screw body 319 passing through the positioning ring 320 rotates in the positioning ring 320.

[0125] For example, Fig.17 As shown, there are two positioning rings 320, and they are symmetrically arranged on both sides of the second nut portion 318 with the second nut portion 318 as the symmetry center. At this time, the second screw body 319 passes through one of the positioning rings 320, the second nut portion 318 and the other positioning ring 320 in sequence, so that the second screw body 319 rotates between the two positioning rings 320. At the same time, the second nut portion 318 moves along the axial direction of the screw nut when the second screw body 319 rotates around the axis. The above-mentioned arrangement of the positioning ring 320 has higher stability.

[0126] Please refer to Fig.17 In one embodiment, the second screw assembly 317 includes a knob 321 connected to one end of the second screw body 319, and the knob 321 extends to the outside of the fixed cover 316. It can be understood that the knob 321 can increase the force application points of the operator on the second screw body 319, and it is more convenient to rotate the second screw body 319.

[0127] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
