DETAILED DESCRIPTION

[0074] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0075] Please also see Figure 1-Figure 5 , the present application provides some embodiments of a rotationally switched vehicle body positioning device.

[0076] like Figure 1As shown, the rotation switching vehicle body positioning device of the present application comprises: a base 1, a rotation component 2, a limit locking component 3 and at least two positioning components 4. The rotation component 2 is rotatably arranged on the base 1; the limit locking component 3 is arranged on the base 1 and is used to limit and lock the rotation of the rotation component 2; the positioning component 4 is arranged on the rotation component 2 and is used to position the vehicle body.

[0077] Specifically, the rotating assembly 2 refers to an assembly that rotates relative to the base 1, the limiting and locking assembly 3 refers to an assembly that limits and locks the rotation of the rotating assembly 2, and the positioning assembly 4 refers to an assembly that positions the vehicle body, and the vehicle bodies positioned by the positioning assemblies 4 are different in model. The rotation of the rotating assembly 2 drives the positioning assembly 4 to rotate, and different positioning assemblies 4 can be switched to position the vehicle bodies of different models.

[0078] Since the limit locking assembly 3 in the present application can limit and lock the rotation of the rotating assembly 2, the positioning assembly 4 can be prevented from rotating too far by limiting the rotating assembly 2. When the positioning assembly 4 is rotated to the right position and locked, the position of the positioning assembly 4 and the limit positioning assembly 4 can be accurately switched, thereby improving the reliability of the vehicle body positioning device.

[0079] In an implementation of the embodiment of the present application, the rotation-switching vehicle body positioning device further includes: a controller which is electrically connected to the rotation component 2 , the limit locking component 3 , and the positioning component 4 , respectively.

[0080] Specifically, the rotating assembly 2, the limit locking assembly 3 and the positioning assembly 4 are controlled by the controller to realize the automatic control of the vehicle body positioning device. For example, when the positioning assembly 4 needs to be switched, the limit locking assembly 3 is first controlled to be unlocked, and then the rotating assembly 2 is controlled to rotate. The limit locking assembly 3 will limit the rotation of the rotating assembly 2. After the rotating assembly 2 rotates to the right position, the limit locking assembly 3 is controlled to lock the rotating assembly 2, and the rotating assembly 2 is controlled to stop rotating, and then the corresponding positioning assembly 4 can be controlled to position the vehicle body.

[0081] In one implementation of the embodiment of the present application, Figure 1-Figure 2 As shown, the rotating assembly 2 includes: a rotating member 21 and a first driving member 22. The rotating member 21 is rotatably connected to the base 1; the first driving member 22 is disposed on the base 1; an extension arm 211 is disposed on the rotating member 21, and the first driving member 22 is rotatably connected to the extension arm 211 and is used to drive the extension arm 211 to rotate.

[0082] Specifically, the rotating member 21 rotates relative to the base 1, and the limit locking assembly 3 limits and locks the rotation of the rotating member 21. An extension arm 211 is formed on the rotating member 21, and the first driving member 22 is rotatably connected to the extension arm 211. The first driving member 22 drives the extension arm 211 to rotate and drives the rotating member 21 to rotate. The extension arm 211 extends in a direction away from the rotation center axis of the rotating member 21, so that the first driving member 22 can drive the rotating member 21 to rotate with a smaller torque.

[0083] In one implementation of the embodiment of the present application, Figure 1-Figure 2 As shown, the rotating member 21 is a cylindrical member.

[0084] Specifically, a cavity is formed inside the cylindrical member, and the cylindrical member has a barrel, which can reduce the weight of the rotating member 21 and make the rotating member 21 easier to rotate. The extension arm 211 is arranged on the outer wall of the cylindrical member. The cylindrical member can be cylindrical, and the extension arm 211 can extend radially of the cylindrical member.

[0085] In one implementation of the embodiment of the present application, Figure 1-Figure 2 As shown, the first driving member 22 is a telescopic driving member; the telescopic driving member is rotatably connected to the base 1, and the telescopic rod of the telescopic driving member is rotatably connected to the extension arm 211.

[0086] Specifically, the first driving member 22 is a telescopic driving member, and the output shaft of the telescopic driving member is a telescopic rod, which is telescopic along its length. The telescopic driving member is rotatably connected to the base 1. During the rotation of the extension arm 211, the movement trajectory of the extension arm 211 is an arc, and the telescopic driving member also needs to rotate to adapt to the rotation of the extension arm 211. During the extension and retraction of the telescopic rod, the telescopic driving member and the rotating member 21 both rotate relative to the base 1. The telescopic driving member can adopt a telescopic cylinder. An axial hole is provided on the extension arm 211, and a wear-resistant sleeve 215 is provided in the axial hole. A rotating shaft is provided in the wear-resistant sleeve 215, and the rotating shaft is connected to the telescopic rod.

[0087] In one implementation of the embodiment of the present application, Figure 1-Figure 3 As shown, the limit locking assembly 3 includes: a stopper 31, a first protrusion 32, a second protrusion 33 and a locker 35. The stopper 31 is arranged on the base 1; the first protrusion 32 and the second protrusion 33 are arranged at intervals on the rotating member 21; the locker 35 is arranged on the base 1 and is used to lock the rotating member 21; when the first protrusion 32 rotates along the first direction with the rotating member 21 to the stopper 31, the locker 35 locks the rotating member 21; when the second protrusion 33 rotates along the second direction with the rotating member 21 to the stopper 31, the locker 35 locks the rotating member 21.

[0088] Specifically, the stopper 31 refers to a component that blocks the protrusion. When the rotating member 21 rotates, the protrusion will be driven to rotate, and the stopper 31 is located on the rotation track of the protrusion. Since the protrusion is blocked by the stopper 31, the rotation range of the rotating member 21 is limited by the stopper 31. There are two protrusions, namely the first protrusion 32 and the second protrusion 33. The first protrusion 32 and the second protrusion 33 may be blocked by the stopper 31, thus forming two blocking positions. When the first protrusion 32 abuts against the stopper 31, it indicates that the rotating member 21 rotates to a blocking position, a certain positioning component 4 reaches a predetermined position and can position the body of the corresponding vehicle model, then the lock 35 can lock the rotating member 21; when the second protrusion 33 abuts against the stopper 31, it indicates that the rotating member 21 rotates to another blocking position, another positioning component 4 reaches a predetermined position and can position the body of the corresponding vehicle model, then the lock 35 can also lock the rotating member 21.

[0089] In one implementation of the embodiment of the present application, Figure 2 As shown, the first protrusion 32 and the second protrusion 33 are connected by an arc-shaped connecting member 34 ; an arc-shaped groove 212 is provided on the outer side of the rotating member 21 , and the arc-shaped connecting member 34 is located in the arc-shaped groove 212 .

[0090] Specifically, the first protrusion 32 and the second protrusion 33 are connected to each other, specifically connected by an arc-shaped connecting member 34, and the arc-shaped connecting member 34 is adapted to the shape of the cylindrical member. An arc-shaped groove 212 is provided on the outer side of the rotating member 21, that is, an arc-shaped groove 212 is provided on the outer side of the cylindrical member, and the arc-shaped groove 212 is provided around the central axis of the cylindrical member. The arc-shaped connecting member 34 is installed in the arc-shaped groove 212, and specifically, the arc-shaped connecting member 34 can be installed in the arc-shaped groove 212 by bolts or screws.

[0091] In one implementation of the embodiment of the present application, Figure 2 As shown, a position sensor 14 is provided on the base 1 for detecting the rotation position of the rotating member 21 .

[0092] Specifically, the position sensor 14 is used to detect the position of the rotating member 21, and specifically can detect that the rotating member 21 rotates to the blocking position. When the rotating member 21 rotates to the blocking position, it is detected by the position sensor 14, and the lock 35 can be controlled to lock the rotating member 21, and the corresponding positioning component 4 can be controlled. Since there are two blocking positions of the rotating member 21, two position sensors 14 can be configured. The position sensor 14 can use a metal sensor 44, and the metal target is set on the rotating member 21, the protrusion or the arc-shaped connecting member 34.

[0093] In an implementation of the embodiment of the present application, the rotationally switched vehicle body positioning device further includes: a controller which is electrically connected to the first driving member 22 , the locker 35 , the positioning assembly 4 , and the position sensor 14 , respectively.

[0094] Specifically, the controller is used to control the first driving member 22, the locker 35, and the positioning assembly 4, and the controller can also receive the sensing signal of the position sensor 14. When the positioning assembly 4 needs to be switched, the controller controls the locker 35 to unlock, and then controls the first driving member 22 to drive the rotating member 21 to rotate, until the sensing signal of the position sensor 14 is received, the locker 35 is controlled to lock, and the control of the first driving member 22 is stopped, and finally the positioning assembly 4 can be controlled.

[0095] In one implementation of the embodiment of the present application, Figure 1-Figure 3 As shown, the rotating member 21 is provided with a first pin hole 213 and a second pin hole 214 at intervals. The locker 35 includes a telescopic latch 351, which can be inserted into the first pin hole 213 or the second pin hole 214; when the first protrusion 32 abuts against the stopper 31, the first pin hole 213 corresponds to the telescopic latch 351; when the second protrusion 33 abuts against the stopper 31, the second pin hole 214 corresponds to the telescopic latch 351.

[0096] Specifically, the rotating member 21 is provided with a first pin hole 213 and a second pin hole 214 at intervals, and the telescopic latch 351 of the locker 35 can be telescopic and inserted into the first pin hole 213 or the second pin hole 214. When the first protrusion 32 abuts against the stopper 31, the first pin hole 213 corresponds to the telescopic latch 351, and the telescopic latch 351 can be inserted into the first pin hole 213; when the second protrusion 33 abuts against the stopper 31, the second pin hole 214 corresponds to the telescopic latch 351, and the telescopic latch 351 can be inserted into the second pin hole 214. By inserting the telescopic latch 351 into the first pin hole 213 or the second pin hole 214, the rotating member 21 can be prevented from rotating, and the position of the rotating member 21 can be ensured to be accurate and reliable.

[0097] In one implementation of the embodiment of the present application, Figure 1-Figure 3 As shown, the lock 35 further includes: a second driving member 352 and a guide sleeve 353. The second driving member 352 is disposed on the base 1 and is electrically connected to the controller; the guide sleeve 353 is sleeved outside the telescopic bolt 351 and is used to guide the telescopic bolt 351 to extend and retract; the telescopic bolt 351 is rotatably connected to the output shaft of the second driving member 352.

[0098] Specifically, the second driving member 352 is used to drive the telescopic bolt 351 to move telescopically, and the guide sleeve 353 covers the telescopic bolt 351 to guide the telescopic movement of the telescopic bolt 351, so as to facilitate the insertion of the telescopic bolt 351 into the first pin hole 213 or the second pin hole 214. For example, an external thread is formed on the output shaft of the second driving member 352, and an internal thread is formed on the telescopic bolt 351. The internal thread and the external thread form a threaded connection. When the output shaft rotates, the telescopic bolt 351 is driven to move telescopically under the guidance of the guide sleeve 353. The second driving member 352 can be a motor or a rotary cylinder. Of course, a telescopic driving member can also be connected to the telescopic bolt 351 to achieve the telescopic movement of the telescopic bolt 351. The telescopic driving member can be a telescopic cylinder.

[0099] In one implementation of the embodiment of the present application, Figure 2 and Figure 4 As shown, the base 1 includes: a support frame 11, a base plate 12 and a bearing assembly 13.

[0100] Specifically, the support frame 11 plays a supporting role, supporting the base plate 12, the bearing assembly 13, the rotating assembly 2, the positioning assembly 4 and the limit locking assembly 3. The rotating member 21 is rotatably connected to the bearing assembly 13, and the rotation of the rotating member 21 relative to the base 1 is realized by the bearing assembly 13. The first driving member 22 is rotatably connected to the base plate 12. The limit locking assembly 3 is arranged on the base plate 12.

[0101] In one implementation of the embodiment of the present application, Figure 1 and Figure 4 As shown, the support frame 11 includes: a bottom plate 111, a top plate 112 and a connecting pipe 113. The two ends of the connecting pipe 113 are respectively connected to the bottom plate 111 and the top plate 112. A reinforcing rib 114 is arranged outside the connecting pipe 113, and the reinforcing rib 114 is connected to the top plate 112.

[0102] Specifically, the size of the top plate 112 is larger than that of the bottom plate 111, and the portion of the top plate 112 extending from the bottom plate 111 (i.e., the extension portion) is connected to the reinforcing rib 114. The bottom plate 111 is provided with connection holes for bolts or screws to pass through so as to install the support frame 11 on other equipment.

The connection between the column 131 and the sleeve 132 is conducive to fixing the column 131 and the sleeve 132 to the base plate 12. Two or more bearings 133 can be provided, so that the rotation of the rotating member 21 is more stable.

[0105] In one implementation of the embodiment of the present application, Figure 1-Figure 2 As shown, a via hole 121 is provided on the substrate 12 , and the column 131 passes through the via hole 121 .

[0106] Specifically, the substrate 12 is provided with a through hole 121, and the column 131 is inserted into the through hole 121, which is beneficial to the connection stability of the column 131. The size of the sleeve 132 is larger than the size of the through hole 121, and the sleeve 132 cannot pass through the through hole 121.

[0107] In one implementation of the embodiment of the present application, Figure 1-Figure 2 As shown, a flange 1311 is provided at one end of the column 131 , and an end plate 1312 is detachably connected to the other end of the column 131 , and the base plate 12 and the sleeve 132 are both located between the flange 1311 and the end plate 1312 .

[0108] Specifically, a flange 1311 is provided at the lower end of the column 131. The flange 1311 cannot pass through the through hole 121, so the base plate 12 limits the flange 1311. The upper end of the column 131 is detachably connected with an end plate 1312. The size of the end plate 1312 is larger than the size of the sleeve 132.
