[0059] The first embodiment of the present application provides a sleeve assembly. Figure 1 , Fig.10 and Fig.12 The sleeve assembly 100 includes a locking and unlocking sleeve 10 and a sleeve changing seat 20 . The locking and unlocking sleeve 10 includes a sleeve seat 11 and a sleeve 12 floatingly mounted on the sleeve seat 11, the sleeve 12 is used to cooperate with the bolt to disassemble and assemble the bolt; the sleeve seat 11 includes a first seat body 111, a rotating arm 112 and a first elastic member 113, the rotating arm 112 is rotatably mounted on the first seat body 111, the rotating arm 112 has a first end 1121 and a second end 1122, the first end 1121 is provided with a clamping portion 11211, the first elastic member 113 is used to apply elastic force to the first end 1121 and / or the second end 1122 so that the clamping portion 11211 is clamped into the clamping slot 201 of the driving mechanism 200; the cartridge changing seat 20 includes a second seat body 21 and an unlocking portion 22 provided on the second seat body 21, the unlocking portion 22 is used to squeeze the second end 1122 so that the clamping portion 11211 is disengaged from the clamping slot 201 of the driving mechanism 200.

[0060] The sleeve 12 is installed in a floating manner on the sleeve seat 11, that is, in the axial direction of the sleeve 12, the sleeve 12 can be close to or away from the sleeve seat 11. Optionally, a second elastic member 13 is provided between the sleeve 12 and the sleeve seat 11. When the sleeve 12 is subjected to an external force, the sleeve 12 can compress the second elastic member 13 to approach the sleeve seat 11. After the external force disappears, the second elastic member 13 recovers to make the sleeve 12 away from the sleeve seat 11. The second elastic member 13 is a compression spring.

[0061] The sleeve 12 is used to cooperate with the bolt to disassemble and assemble the bolt, that is, the sleeve 12 has a cavity 121 adapted to the head of the bolt; after the head of the bolt enters the cavity 121, the bolt will rotate with the sleeve 12 to achieve loosening or tightening of the bolt.

[0062] The rotating arm 112 is rotatably mounted on the first base 111, wherein the rotating axis of the rotating arm 112 is between the first end 1121 and the second end 1122 of the rotating arm 112, so that the rotating arm 112 and the first base 111 together form a seesaw-like structure. It should be noted that the rotating axis of the rotating arm 112 is parallel or almost parallel to the central axis of the sleeve 12.

[0063] Optionally, a second accommodating groove 1114 is provided on the outer circumferential surface of the first seat body 111 , and the rotating arm 112 is located in the second accommodating groove 1114 .

[0064] Optionally, see Fig. 9 and Fig.10 The first seat body 111 is provided with a rotating shaft 11213, the central axis of the rotating shaft 11213 is the rotating axis of the rotating arm 112, and the rotating arm 112 has a through hole for the rotating shaft 11213 to pass through. It can be understood that the rotating shaft 11213 is fixedly connected to the first seat body 111 (can be but not limited to welding), and the rotating shaft 11213 can rotate relative to the rotating arm 112; or, the rotating shaft 11213 can rotate relative to the first seat body 111, and the rotating shaft 11213 is fixedly connected to the rotating arm 112 (can be but not limited to welding); or, the rotating shaft 11213 can rotate relative to the first seat body 111 and relative to the rotating arm 112. Among them, the rotating shaft 11213 can be a pin.

[0065] Optionally, the rotating shaft 11213 is located in the middle of the rotating arm 112, so that locking and unlocking are more labor-saving.

[0066] The first elastic member 113 is used to apply an elastic force to the first end 1121 and / or the second end 1122. It can be understood that the first elastic member 113 applies an elastic force to the first end 1121, or the first elastic member 113 applies an elastic force to the second end 1122, or the first elastic member 113 applies an elastic force to both the first end 1121 and the second end 1122.

[0067] Under the elastic force of the first elastic member 113 , the engaging portion 11211 of the first end 1121 is inserted into the engaging groove 201 of the driving mechanism 200 along the radial direction of the first seat body 111 , so that the sleeve seat 11 cannot move axially relative to the driving mechanism 200 in the first seat body 111 .

[0068] The unlocking portion 22 is used to squeeze the second end 1122 so that the clamping portion 11211 is disengaged from the clamping slot 201 of the driving mechanism 200. It can be understood that when the unlocking portion 22 squeezes the second end 1122, the movement directions of the first end 1121 and the second end 1122 are opposite, and the first end 1121 overcomes the elastic force of the first elastic member 113, so that the clamping portion 11211 on the first end 1121 is disengaged from the clamping slot 201 of the driving mechanism 200 along the radial direction of the first seat body 111, thereby realizing the unlocking of the sleeve seat 11.

[0069] Optionally, a rotation-stopping recess 1113 is provided on the first seat body 111, and the rotation-stopping recess 1113 is used to cooperate with the rotation-stopping protrusion 203 of the driving end of the driving mechanism 200 to stop the rotation, so as to realize that the driving mechanism 200 drives the sleeve seat 11 to rotate; wherein, the rotation-stopping recess 1113 is provided at the middle position of the first seat body 111, and correspondingly, the rotation-stopping protrusion 203 is provided at the middle position of the driving end of the driving mechanism 200. For example, the rotation-stopping recess 1113 is a square groove, and the rotation-stopping protrusion 203 is a square column; or, the rotation-stopping recess 1113 is a hexagonal groove, and the rotation-stopping protrusion 203 is a hexagonal column. Of course, the rotation-stopping recess 1113 can also be provided at the driving end of the driving mechanism 200, and the rotation-stopping protrusion 203 can be provided on the first seat body 111.

[0070] The beneficial effects of the sleeve assembly 100 provided in the embodiment of the present application are as follows: when the sleeve seat 11 is installed at the output end of the driving mechanism 200 through the first seat body 111, the first elastic member 113 applies an elastic force to the first end 1121 of the rotating arm 112 and / or the second end 1122 of the rotating arm 112, so that the clamping portion 11211 of the first end 1121 is clamped in the clamping groove 201 of the driving mechanism 200, thereby locking the sleeve seat 11 at the output end of the driving mechanism 200; at this time, the driving mechanism 200 can drive the sleeve seat 11 to rotate, thereby driving the sleeve 12 on the sleeve seat 11 to disassemble and assemble the bolts. When it is necessary to replace other locking and unlocking sleeves 10, the unlocking portion 22 on the second seat body 21 of the sleeve changing seat 20 squeezes the second end 1122 of the rotating arm 112 to make the clamping portion 11211 on the first end 1121 of the rotating arm 112 disengage from the clamping slot 201 of the driving mechanism 200, thereby unlocking the sleeve seat 11, and the locking and unlocking sleeve 10 can be removed from the output end of the driving mechanism 200, making disassembly more convenient and solving the problem of the complicated replacement process of the locking and unlocking sleeve 10.

[0071] In some embodiments, a plurality of locking and unlocking sleeves 10 are provided, and each locking and unlocking sleeve 10 is different from another, and the difference includes interface size, elastic member strength, etc., so that the plurality of locking and unlocking sleeves 10 can adapt to the disassembly and assembly of bolts of different models, that is, the plurality of locking and unlocking sleeves 10 can be applied to different vehicle models; and, because the locking and unlocking sleeves 10 are adapted to the bolts, the problem of noise in the vehicle when locking and unlocking is reduced or avoided. It should be noted that the structures of the sleeve seats 11 of the plurality of locking and unlocking sleeves 10 are all consistent.

[0072] Please refer to Figure 1 and Figure 2 In some embodiments, the first end 1121 is also provided with a locking fit portion 11212, which is located on one side of the rotating arm 112 in the axial direction of the sleeve 12; the first elastic member 113 is an elastic band used to apply elastic force to the locking fit portion 11212 so that the clamping portion 11211 is clamped into the clamping slot 201 of the driving mechanism 200.

[0073] Optionally, the locking fitting portion 11212 is a pin fixed to the first end 1121 of the rotating arm 112, and the extending direction of the pin is consistent with the axial direction of the first seat body 111. Of course, the locking fitting portion 11212 can also be a bump fixed or integrally formed on the first end 1121 of the rotating arm 112.

[0074] The locking fitting portion 11212 is located on one side of the rotating arm 112 in the axial direction of the first seat body 111. It can be understood that if the axial direction of the first seat body 111 is a vertical direction, the locking fitting portion 11212 can be located on the upper side of the rotating arm 112 or on the lower side of the rotating arm 112. Figure 4 The second base body 21 is provided with an escape groove 211 for escaping the first elastic member 113 , so as to prevent the second base body 21 from squeezing the first elastic member 113 and causing damage to the first elastic member 113 .

[0075] The first elastic member 113 is an elastic band used to apply elastic force to the locking fitting portion 11212 . It can be understood that the first elastic member 113 indirectly applies elastic force to the first end 1121 so that the clamping portion 11211 of the first end 1121 is clamped into the clamping slot 201 of the driving mechanism 200 .

[0076] Optionally, the first elastic member 113 is wound around the outer circumferential surface of the first base body 111 , and in the radial direction of the first base body 111 , the locking fitting portion 11212 is located on the inner side of the first elastic member 113 .

[0077] Based on the above solution, the first elastic member 113 is designed as an elastic band, and the first elastic member 113 can be wound around the outer circumference of the first seat body 111 , which is beneficial to the arrangement of the first elastic member 113 .

[0078] In other embodiments, the first elastic member 113 may be a tension spring disposed between the first end 1121 of the rotating arm 112 and the first seat body 111, and the tension spring applies a radially inward tension force along the first seat body 111 to the first end 1121, so that the clamping portion 11211 of the first end 1121 is clamped into the clamping slot 201 of the driving mechanism 200. Alternatively, the first elastic member 113 may be a compression spring disposed between the second end 1122 of the rotating arm 112 and the first seat body 111, and the compression spring applies a radially outward thrust force along the first seat body 111 to the second end 1122, so that the clamping portion 11211 of the first end 1121 is clamped into the clamping slot 201 of the driving mechanism 200. Alternatively, the first elastic member 113 includes an elastic band for applying an elastic force to the locking fitting portion 11212 and a compression spring for applying a radially outward thrust force along the first seat body 111 to the second end 1122.

[0079] Please refer to Figure 1 In some embodiments, the first elastic member 113 is an annular elastic band sleeved on the outer circumference of the first base body 111 .

[0080] The first elastic member 113 may be an annular spring, a rubber ring, etc.

[0081] Based on the above solution, the first elastic member 113 can be directly sleeved on the outer peripheral surface of the first base body 111 , which is further beneficial to the installation of the first elastic member 113 .

[0082] In other embodiments, the first elastic member 113 is wrapped around a portion of the outer circumference of the first base body 111, both ends of the first elastic member 113 are fixed on the outer circumference of the first base body 111, and the locking fitting portion 11212 is between the two ends of the first elastic member 113 and located on the inner side of the first elastic member 113.

[0083] Please refer to Figure 1 and Figure 2 In some embodiments, based on the fact that the first elastic member 113 is an annular elastic band, an annular groove 1112 is provided on the outer circumferential surface of the first seat body 111 , and the annular elastic band is located in the annular groove 1112 .

[0084] Optionally, the annular groove 1112 is formed by a depression in the outer peripheral surface of the first seat body 111. It can be understood that the cross section of the annular groove 1112 can be semicircular, rectangular, V-shaped, trapezoidal, etc.

[0085] Based on the above solution, in the axial direction of the first seat body 111, the annular groove 1112 can limit the annular elastic band to prevent the annular elastic band from moving in the axial direction of the first seat body 111, thereby ensuring the stability of the annular elastic band.

[0086] In other embodiments, the annular groove 1112 may not be provided on the outer circumferential surface of the first seat body 111, but a plurality of first limiting protrusions and a plurality of second limiting protrusions may be provided on the outer circumferential surface of the first seat body 111, the plurality of first limiting protrusions are arranged at intervals along the circumference of the first seat body 111, and the plurality of second limiting protrusions are arranged at intervals along the circumference of the first seat body 111; in the axial direction of the first seat body 111, the plurality of first limiting protrusions are located on one side of the annular elastic band, and the plurality of second limiting protrusions are located on the other side of the annular elastic band, and the annular elastic band is limited by the plurality of first limiting protrusions and the plurality of second limiting protrusions to prevent the annular elastic band from moving in the axial direction of the first seat body 111.

[0087] Please refer to Figure 1 and Figure 2 In some embodiments, a first receiving groove 1111 is provided on the outer circumference of the first seat body 111, and the first receiving groove 1111 is for the locking fitting portion 11212 to enter. The first receiving groove 1111 is connected to the second receiving groove 1114. Please refer to Figures 3 to 6 After the unlocking portion 22 of the cartridge changing seat 20 squeezes the second end 1122 of the rotating arm 112 , the locking fitting portion 11212 overcomes the elastic force of the first elastic member 113 and escapes from the first receiving groove 1111 .

[0088] Optionally, the first receiving groove 1111 is formed by a depression in the outer peripheral surface of the first seat body 111. It can be understood that the cross section of the first receiving groove 1111 can be semicircular, rectangular, V-shaped, trapezoidal, etc.

[0089] Optionally, the locking fitting portion 11212 extends along the axial direction of the first base body 111 . For example, the locking fitting portion 11212 is a pin shaft. Correspondingly, the first receiving groove 1111 extends along the axial direction of the first base body 111 .

[0090] By adopting the above technical solution, the overall structure of the sleeve seat 11 is made more compact and the aesthetics is also improved.

[0091] Please refer to Figure 1 In some embodiments, a plurality of rotating arms 112 are arranged at intervals along the circumference of the first seat body 111 .

[0092] It is understood that two or three rotating arms 112 may be arranged at intervals along the circumference of the first seat body 111. When two rotating arms 112 are arranged at intervals along the circumference of the first seat body 111, the two rotating arms 112 are symmetrically distributed around the center of the first seat body 111 to ensure uniform force.

[0093] It should be noted that when there are multiple rotating arms 112 , there are correspondingly multiple unlocking portions 22 , and each unlocking portion 22 is used to squeeze the second end 1122 of a rotating arm 112 to unlock.

[0094] Based on the above solution, by providing a plurality of rotating arms 112 , the stability of fixing the sleeve seat 11 on the output end of the driving mechanism 200 can be improved.

[0095] In other embodiments, one rotating arm 112 may also be provided.

[0096] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the sleeve seat 11 further includes a plurality of hanging portions 114 disposed on the first seat body 111 . When the unlocking portion 22 of the cartridge changing seat 20 squeezes the second end 1122 , the sleeve seat 11 is hung on the second seat body 21 through the plurality of hanging portions 114 .

[0097] Optionally, two hanging parts 114 are provided, and the two hanging parts 114 are symmetrically distributed around the center of the first base body 111 to ensure uniform force.

[0098] Optionally, the hanging portion 114 is an L-shaped structure. Of course, the hanging portion 114 may also be a U-shaped structure with an opening toward the radial outer side of the first seat body 111 .

[0099] Based on the above solution, when the unlocking portion 22 of the cartridge changing seat 20 squeezes the second end 1122, the sleeve seat 11 can be unlocked, so that the sleeve seat 11 can be separated from the output end of the driving mechanism 200; because the sleeve seat 11 is suspended on the second seat body 21 through a plurality of suspension portions 114, the sleeve seat 11 can move with the cartridge changing seat 20. Therefore, the cartridge changing seat 20 not only plays the role of unlocking the sleeve seat 11, but also plays the role of moving the sleeve seat 11. In this way, after the sleeve seat 11 is unlocked, there is no need to design an additional manipulator to move the unlocking sleeve 10, thereby simplifying the structure.

[0100] Optionally, a plurality of cartridge changing seats 20 and locking and unlocking sleeves 10 may be provided, and each cartridge changing seat 20 may support one locking and unlocking sleeve 10 .

[0101] In other embodiments, the hanging portion 114 may not be provided on the first seat body 111. After the unlocking portion 22 of the cartridge changing seat 20 squeezes the second end 1122 of the rotating arm 112 to unlock the sleeve seat 11, an additionally provided manipulator is used to move the locking and unlocking sleeve 10 away from the output end of the driving mechanism 200.

[0102] Please refer to Figure 1In some embodiments, the unlocking portion 22 has a guiding slope 221 , and the guiding slope 221 is used to guide the unlocking portion 22 to squeeze the second end 1122 .

[0103] Optionally, two unlocking parts 22 are provided, and the guiding inclined surfaces 221 of the two unlocking parts 22 are arranged opposite to each other to form a flaring structure, so that the two unlocking parts 22 can squeeze the second ends 1122 of the two rotating arms 112 at the same time.

[0104] The unlocking portion 22 also has a first straight surface, and the rotating arm 112 also has a second straight surface between the first end 1121 and the second end 1122; after the cartridge holder 20 moves into position, the first straight surface fits with the second straight surface to keep the cartridge holder 11 in the unlocked state.

[0105] Please refer to Figure 1 , Figure 3 , Figure 7 and Figure 8 In some embodiments, the cartridge changing seat 20 moves radially along the sleeve seat 11 so that the unlocking portion 22 squeezes the second end 1122; the second seat body 21 is also provided with a stopping portion 24 that cooperates with the first seat body 111 along the moving direction of the cartridge changing seat 20.

[0106] It can be understood that the stopping portion 24 can be integrally formed with the first base body 111; or, the stopping portion 24 can be fixed to the first base body 111 by welding, fastener connection, clamping, etc.

[0107] The stopping portion 24 cooperates with the first seat body 111 to ensure that the cartridge changing seat 20 moves to an accurate position, thereby ensuring that the sleeve seat 11 is unlocked.

[0108] Please refer to Figure 1 , Figure 3 , Figure 7 and Figure 8 In some embodiments, the second seat body 21 is further provided with a position sensor 23 for detecting whether the cartridge changing seat 20 moves into position along the radial direction of the sleeve seat 11 .

[0109] Optionally, the second base body 21 is disposed on an overhanging plate, and the position sensor 23 is fixed on the overhanging plate.

[0110] Optionally, the in-position sensor 23 is a proximity sensor. When the edge of the first seat body 111 is below the in-position sensor 23, the proximity sensor is triggered, and the cartridge changer 20 stops moving radially along the sleeve seat 11. At this time, the sleeve seat 11 has been unlocked, and the cartridge changer 20 can move axially along the sleeve seat 11 to drive the locking and unlocking sleeve 10 to disengage from the driving mechanism 200.

[0111] Please refer to Figure 1 , Fig.11 and Fig.12 The second aspect of the present application provides a locking and unlocking device 1.
