[0034] As shown in Figures 1 to 9 The embodiment provides a clamp structure, which comprises a main frame 1, the main frame 1 is used for being connected with a robot, and the main frame 1 has a height direction z and a width direction x intersecting with each other.

[0035] In addition, the main frame 1 also has a length direction y intersecting with the height direction z and the width direction x.

[0036] Further, the clamp structure also comprises a first clamping assembly 2, the first clamping assembly 2 is used for clamping a seat mounting support 4, and the first clamping assembly 2 comprises a first clamping piece 21 and a second clamping piece 22 which are oppositely arranged along the height direction z, the first clamping piece 21 is movably connected with the main frame 1, the first clamping piece 21 can move along the height direction z towards or away from the second clamping piece 22, so as to increase or decrease the distance between the first clamping piece 21 and the second clamping piece 22, and the second clamping piece 22 is connected with the main frame 1.

[0037] Furthermore, the clamping structure also includes a second clamping component 3, which is used to clamp the seat mounting bracket 4. The second clamping component 3 and the first clamping component 2 are spaced apart from each other along the width direction x. The second clamping component 3 is movably connected to the main frame 1 and can move along the width direction x towards or away from the first clamping component 2.

[0038] In this embodiment, the clamping structure includes two first clamping components 2 arranged opposite each other along the length direction y and two second clamping components 3 arranged opposite each other along the length direction y. Only one first clamping component 2 and one second clamping component 3 are described in detail below. The other first clamping component 2 and the other second clamping component 3 can be implemented with reference to this embodiment.

[0039] In this embodiment, when the main frame 1 is connected to the robot, if the seat mounting bracket 4 needs to be placed on the upper part of the rear floor of the vehicle body 6, the first clamping member 21 can be moved away from the second clamping member 22 along the height direction z to increase the distance between the first clamping member 21 and the second clamping member 22. Then, the seat mounting bracket 4 can be placed between the first clamping member 21 and the second clamping member 22. Then, the first clamping member 21 can be moved closer to the second clamping member 22 along the height direction z to reduce the distance between the first clamping member 21 and the second clamping member 22. The distance between the two clamping components 22 is adjusted so that the seat mounting bracket 4 can be clamped by the first clamping component 21 and the second clamping component 22. At the same time, the second clamping component 3 can be moved along the width direction x towards or away from the first clamping component 2 to adjust the position of the second clamping component 3 relative to the seat mounting bracket 4, thereby clamping the seat mounting bracket 4. Finally, the movement of the robot drives the main frame 1, the first clamping component 2 and the second clamping component 3 into the vehicle body 6 to place the seat mounting bracket 4 on the upper end of the rear floor of the vehicle body 6.

[0040] In summary, by using a clamping structure to place the seat mounting bracket 4 on the upper part of the rear floor of the vehicle body 6, not only can manpower be saved and production line efficiency be improved, but damage to the door frame of the vehicle body 6 can also be avoided due to the instability of manually handling the seat mounting bracket 4.

[0041] Combination Figure 1 , Figure 2 and Figure 5 As shown, the second clamping member 22 includes a second clamping part 221 and a second connecting part 222. The second clamping part 221 is disposed opposite to the first clamping member 21 along the height direction z. The first end a of the second clamping part 221 is hinged to the second connecting part 222. The second end b of the second clamping part 221 can rotate in a direction closer to or farther from the first clamping member 21 to increase or decrease the distance between the first clamping member 21 and the second clamping part 221. The second connecting part 222 is connected to the main frame 1.

[0042] Specifically, when the second end b of the second clamping part 221 rotates in a direction away from the first clamping part 21, the distance between the first clamping part 21 and the second clamping part 221 increases; when the second end b of the second clamping part 221 rotates in a direction close to the first clamping part 21, the distance between the first clamping part 21 and the second clamping part 221 decreases.

[0043] In the embodiment, when the first clamping assembly 2 needs to clamp the seat mounting bracket 4, the first clamping part 21 can first move in the height direction z in a direction away from the second clamping part 221, while the second end b of the second clamping part 221 rotates in a direction away from the first clamping part 21, so as to increase the distance between the first clamping part 21 and the second clamping part 221, and then the seat mounting bracket 4 can be placed between the first clamping part 21 and the second clamping part 221; then the first clamping part 21 moves in the height direction z in a direction close to the second clamping part 221, while the second end b of the second clamping part 221 rotates in a direction close to the first clamping part 21, so as to decrease the distance between the first clamping part 21 and the second clamping part 221, and then the seat mounting bracket 4 is clamped by the first clamping part 21 and the second clamping part 221.

[0044] It should be understood that the movement of the first clamping part 21 and the rotation of the second clamping part 221 should be synchronized to increase or decrease the distance between the first clamping part 21 and the second clamping part 221.

[0045] In the embodiment, the rotation of the second clamping part 221 can also increase or decrease the distance between the first clamping part 21 and the second clamping part 221, so that the maximum distance between the first clamping part 21 and the second clamping part 221 is increased, so as to facilitate the first clamping assembly 2 to clamp the seat mounting bracket 4, and also facilitate to improve the versatility of the first clamping assembly 2 to clamp different seat mounting brackets 4.

[0046] In combination with the figures shown in Figure 1 , Figure 2 and Figure 5 , the clamp structure further comprises a first driving part 51 and a second driving part 52, the first driving part 51 is connected with the main frame 1 and the first clamping part 21, so as to drive the first clamping part 21 to move in the height direction z in a direction close to or away from the second clamping part 22, and the second driving part 52 is connected with the second clamping part 221 and the second connecting part 222, so as to drive the second end b of the second clamping part 221 to rotate in a direction close to or away from the first clamping part 21.

[0047] In the embodiment, the first driving member 51 is a first cylinder, the cylinder body of the first cylinder is connected with the main body frame 1, and the end of the piston rod of the first cylinder is connected with the first clamping member 21. The first cylinder can provide power for the first clamping member 21, so that the first clamping member 21 can move along the height direction z towards the direction of approaching or moving away from the second clamping member 22, thereby increasing or reducing the distance between the first clamping member 21 and the second clamping part 221, so as to open or close the first clamping assembly 2.

[0048] In addition, the first cylinder further comprises a first air outlet pipe and a first air inlet pipe, both of which are in communication with the cylinder body of the first cylinder, the first air outlet pipe is used for outputting compressed air, and the first air inlet pipe is used for inputting compressed air.

[0049] Specifically, when the compressed air in the cylinder body of the first cylinder is output, the piston rod of the first cylinder retracts, the first clamping member 21 moves along the height direction z towards the direction of moving away from the second clamping part 221, and the distance between the first clamping member 21 and the second clamping part 221 increases; when the compressed air is input into the cylinder body of the first cylinder, the piston rod of the first cylinder extends, the first clamping member 21 moves along the height direction z towards the direction of approaching the second clamping part 221, and the distance between the first clamping member 21 and the second clamping part 221 decreases.

[0050] For the specific structure of the first cylinder, please refer to the prior art, which will not be described here.

[0051] In the embodiment, the second driving member 52 is a second cylinder, the cylinder body of the second cylinder is connected with the second connecting part 222, and the end of the piston rod of the second cylinder is hinged with the second clamping part 221. The second cylinder can provide power for the second clamping part 221, so that the second clamping part 221 can rotate towards the direction of approaching or moving away from the first clamping member 21, thereby increasing or reducing the distance between the first clamping member 21 and the second clamping part 221, so as to open or close the first clamping assembly 2.

[0052] In addition, the second cylinder further comprises a second air outlet pipe and a second air inlet pipe, both of which are in communication with the cylinder body of the second cylinder, the second air outlet pipe is used for outputting compressed air, and the second air inlet pipe is used for inputting compressed air.

[0053] Specifically, when the compressed air in the cylinder body of the second cylinder is output, the piston rod of the second cylinder retracts, the second clamping part 221 rotates towards the direction of moving away from the first clamping member 21, and the distance between the second clamping part 221 and the first clamping member 21 increases; when the compressed air is input into the cylinder body of the second cylinder, the piston rod of the second cylinder extends, the second clamping part 221 rotates towards the direction of approaching the first clamping member 21, and the distance between the first clamping member 21 and the second clamping part 221 decreases.

[0054] For the specific structure of the second cylinder, please refer to the prior art, which will not be described here.

[0055] In combination Figure 2 and Figure 5 As shown in the figure, the second clamping part 221 is provided with a first locking hole between the first end a and the second end b; the second clamping part 22 further comprises a first locking part 223, the first locking part 223 comprising a first fixed segment and a first locking segment, the first fixed segment being provided through the second connecting part 222 and connected with the second connecting part 222, the first fixed segment being movably connected with the first locking segment, the first locking segment being able to stretch or contract along the length direction y towards the direction of approaching or moving away from the second clamping part 221.

[0056] Further, when the first locking segment is in the first locking position, the first locking segment is located in the first locking hole and abuts against the hole wall of the first locking hole, so as to limit the rotation of the second clamping part 221 relative to the second connecting part 222; when the first locking segment is in the first unlocking position, the first locking segment is located outside the first locking hole, so that the second clamping part 221 can rotate relative to the second connecting part 222.

[0057] In this embodiment, the first locking part 223 further comprises a first spring and a first electromagnet which are spaced from each other, the first spring being located in the first accommodating groove of the first fixed segment, one end of the first spring being connected with the bottom groove wall of the first accommodating groove, the other end of the first spring being connected with the first locking segment, the first electromagnet being located in the first accommodating groove and oppositely arranged with the first locking segment along the length direction y, the first electromagnet being connected with the groove wall of the first accommodating groove. The first locking segment is made of ferromagnetic metal such as iron and nickel.

[0058] It should be understood that the ferromagnetic metal refers to a metal that can be magnetized and maintain magnetism in an external magnetic field.

[0059] When the second clamping part 221 needs to rotate, the first electromagnet can be energized, the first electromagnet generates a magnetic field, the first electromagnet attracts the first locking segment to contract along the length direction y towards the direction of moving away from the second clamping part 221, the first locking segment compresses the first spring, at this time, the first locking segment is located outside the first locking hole, so that the second clamping part 221 can rotate relative to the second connecting part 222, and further, the second clamping part 221 can rotate towards the direction of approaching or moving away from the first clamping part 21.

[0060] When the second clamping part 221 clamps the seat mounting bracket 4, the first electromagnet can be powered off, the first electromagnet cannot generate a magnetic field, the first locking section is stretched along the length direction y to the direction close to the second clamping part 221 by the elastic restoring force of the first spring, the first spring is restored to normal, at this time, the first locking section is located in the first locking hole and abuts against the hole wall of the first locking hole to limit the rotation of the second clamping part 221 relative to the second connecting part 222, and further limit the rotation of the second clamping part 221 to the direction close to or away from the first clamping part 21.

[0061] It should be understood that whether the first electromagnet is powered on or not can be controlled by an electronic signal.

[0062] In the embodiment, when the second clamping part 221 clamps the seat mounting bracket 4, the second cylinder can provide sufficient power for the second clamping part 221 to clamp the seat mounting bracket 4 to prevent the second clamping part 221 from rotating relative to the second connecting part 222, that is, primary locking; at the same time, the first locking section can lock the second clamping part 221 to prevent the second clamping part 221 from rotating relative to the second connecting part 222 due to the failure of the second cylinder, that is, secondary locking.

[0063] In other embodiments, the first locking part 223 can be a common bolt, and the first locking part 223 is detachably connected with the second connecting part 222 and the second clamping part 221. The first locking part 223 can be simultaneously provided in the second connecting part 222 and the first locking hole, the first locking part 223 is connected with the second connecting part 222, and the first locking part 223 abuts against the hole wall of the first locking hole to limit the rotation of the second clamping part 221 relative to the second connecting part 222; or the first locking part 223 can be simultaneously separated from the second connecting part 222 and the second clamping part 221, so that the second clamping part 221 can rotate relative to the second connecting part 222.

[0064] In combination Figure 7 As shown, the side of the second clamping part 221 close to the first clamping part 21 is provided with a limiting protrusion c, and the limiting protrusion c matches the seat mounting hole 401 of the seat mounting bracket 4 to limit the clamping position of the seat mounting bracket 4.

[0065] It should be understood that the seat mounting hole 401 is used to connect with the second row seat of the vehicle. The matching of the limiting protrusion c and the seat mounting hole 401 of the seat mounting bracket 4 means that the shape, size and position of the limiting protrusion c match the shape, size and position of the seat mounting hole 401.

[0066] In the embodiment, when the first clamping part 21 and the second clamping part 221 clamp the seat mounting support 4, the limiting protrusion c is located in the seat mounting hole 401 of the seat mounting support 4 to limit the clamping position of the seat mounting support 4, so that the seat mounting support 4 cannot move in the plane formed by the width direction x and the length direction y, which is beneficial to improve the stability and accuracy of clamping the seat mounting support 4 by the first clamping part 21 and the second clamping part 221.

[0067] In addition, the first clamping part 21 is provided with a avoiding groove 201 on the side close to the second clamping part 221, the avoiding groove 201 is matched with the limiting protrusion c, when the first clamping part 21 and the second clamping part 221 are in contact, the limiting protrusion c is located in the avoiding groove 201, the avoiding groove 201 is used for avoiding the limiting protrusion c, so as to avoid that the first clamping part 21 damages the limiting protrusion c.

[0068] It should be understood that the avoiding groove 201 is matched with the limiting protrusion c, which means that the shape, size and position of the avoiding groove 201 are matched with the shape, size and position of the limiting protrusion c.

[0069] In combination with Figures 1 to 3 As shown, the main body frame 1 comprises a main body part 11 and a sliding part 12, the main body part 11 is slidingly connected with the sliding part 12, the sliding part 12 is movably connected with the second clamping assembly 3, the sliding part 12 and the second clamping assembly 3 slide synchronously along the length direction y relative to the main body part 11, the main body part 11 is movably connected with the first clamping part 21, the main body part 11 is connected with the second connecting part 222, and the main body part 11 is used for connecting with the robot.
