The transmission member 50 includes a cam 501 and a cam shaft 503.
Further, the cam 501 includes a first surface 5011 and a second surface 5013 opposite the first surface 5011. In this embodiment, the first surface 5011 is provided with a recess 5015. The end of the connecting portion 403 away from the cover 303 is accommodated in the recess 5015, so that the driving member 50 is connected to the switch 40. Preferably, the recess 5015 is a hexagon socket. The second surface 5013 is a cam surface. The second surface 5013 is a mixed surface comprising a highest surface 5016, a lowest surface 5017 and a transition surface 5018, wherein the transition surface connects the highest surface 5016 and the lowest surface 5017 in a smooth manner. Wherein the highest face 5016 is closer to the switch 40 than the lowest face 5017.
The cam shaft 503 is disposed at the center of the second surface 5013. Wherein the cam 501 and the cam shaft 503 are integrated, and the cam 501 and the cam shaft 503 rotate synchronously. The center of the cam shaft 503 is provided with a connecting via 5031.
In this embodiment, the switch 40 passes through the second opening 3051, the switch body 401 is just contained in the containing groove 3031, the connecting portion 403 passes through the first opening 3033, the positioning ring 4031 abuts against the first surface 5011, and meanwhile, the driving ring 4032 is located in the groove 5015 and does not abut against the bottom surface of the groove 5015, so as to achieve a good driving effect of the driving ring 4032 on the driving member 50. In this embodiment, a connecting piece is further used to connect and penetrate through the connecting via 5031, and then is locked in the connecting hole 4033, so as to realize the fixed connection between the driving piece 50, the switch 40 and the cover 303. The cover 303 is fixedly connected to the body 301 by screws. The decoration panel 305 covers the cover 303 and is also fixedly connected with the body 301.

The holding portion 603 is used for holding the electronic device disposed on the base 10. Accordingly, referring to fig. 5, a through hole 3015 is formed in the bottom plate 3011 of the body 301. The holding portion 603 may be exposed from the bottom plate 3011 through the through hole 3015 to hold the electronic device disposed on the base 10. In this way, when the handle 402 is turned, the cam 501 connected to the connecting portion 403 and the cam shaft 503 are driven to rotate synchronously, so that the contact portion 601 abutting against the second surface 5013 rotates, and the abutting portion 603 is driven to move in a direction opposite to or opposite to the cover 303. When the contact portion 601 gradually contacts the lowest surface 5017 of the cam 501, the abutting portion 603 moves in a direction opposite to the cover 303, so that the abutting portion 603 gradually exposes out of the bottom plate 3011 through the through hole 3015, so as to abut against an electronic device disposed on the base 10, and further fix the electronic device together with the base 10, so as to achieve locking. When the contact portion 601 gradually contacts the highest surface 5016 of the cam 501, the abutting portion 603 moves in a direction opposite to the cover 303, so that the abutting portion 603 gradually retracts to the accommodating space 3014 through the through hole 3015, and the abutting portion 603 is separated from abutting the electronic device, so as to realize unlocking.
Further, referring to fig. 3 again, in this embodiment, the latch structure 20 further includes a connecting member 70. The abutment 60 is rotatably connected to the cam shaft 503 by the connection 70.
The connector 70 includes a fixing portion 701 and an elastic portion 702.
Further, the fixing portion 701 includes a bottom wall 7011, a first side wall 7012, and a second side wall 7013 disposed opposite to the first side wall. Two second side walls 7013 are disposed on opposite sides of the bottom wall 7011. The first side wall 7012 is disposed on the bottom wall 7011 and connects the two second side walls 7013.
The bottom wall 7011 is provided with a mounting hole 7014, and each of the second side walls 7013 is provided with a through hole 7016. The two through holes 7016 are disposed opposite to each other.
The fixing part 701 further comprises a lug 7017. The lugs 7017 are protruded on the surface of each second side wall 7013 away from the bottom wall 7011, and screw holes are further formed on the lugs 7017.
In this embodiment, the fixing portion 701 is fixed to the base plate 3011 by using screws, through screw holes formed in the lugs 7017, and through the mounting holes 7014. The lug 7017 may be further attached to the base plate 3011 by an adhesive or a clamping connection.
In this embodiment, the elastic portion 702 is a torsion spring. The elastic portion 702 includes a first elastic arm 7021, a second elastic arm 7022, and a connection ring 7023. The first elastic arm 7021 and the second elastic arm 7022 are formed by extending the connection ring 7023 in different directions.
Accordingly, an end of the contact portion 601 remote from the abutting portion 603 is provided with a connection hole 6011. The connection hole 6011 is a through hole. A partition 6012 is arranged in the middle of the end part of the contact part 601; the two second side walls 7013 are located at the partition 6012, and the through holes 7016 and the connecting holes 6011 are opposite to each other; meanwhile, the first side wall 7012 and the two second side walls 7013 together define a receiving space, and the elastic portion 702 is located in the receiving space.
In this embodiment, the device further comprises a connection pivot 80, wherein the connection pivot 80 is installed from one end of the connection hole 6011, penetrates through the through hole 7016 and the connection ring 7023 in sequence, and is connected to the other end of the connection hole 6011; that is, the abutting piece 60, the elastic portion 702 and the fixing portion 701 are connected together by the connecting pivot 80, and can rotate relatively around the connecting pivot 80; the first elastic arm 7021 abuts against the contact portion 601, and the second elastic arm 7022 abuts against a surface of the bottom wall 7011 facing the first elastic arm 7021.
Thus, referring to fig. 9 and 10, the locked and unlocked states of the latch structure 20 are illustrated. When the handle 402 is turned, the cam 501 connected to the connecting portion 403 and the cam shaft 503 are synchronously turned, so that the contact portion 601 abutting against the second surface 5013 is turned. At this time, in order to gradually contact the contact portion 601 with the lowest surface 5017 of the cam 501, the abutting portion 603 moves in a direction opposite to the cover 303, so that the abutting portion 603 gradually exposes from the through hole 3015 to the bottom plate 3011 to abut against an electronic device mounted on the base 10, and further fix the electronic device together with the base 10, thereby achieving locking, as shown in fig. 9. The first elastic arm 7021 abuts against the contact portion 601, and the second elastic arm 7022 abuts against the bottom wall 7011, so that the elastic portion 702 is simultaneously pressed by the contact portion 601 and the two sides of the bottom wall 7011 to generate elastic compression deformation in a process that the contact portion 601 gradually contacts the lowest surface 5017 of the cam 501, and has elastic force for recovering toward the deformation of the contact portion 601.
If the handle 402 is rotated reversely, at this time, the contact portion 601 gradually contacts the highest surface 5016 of the cam 501 under the action of the elastic force generated by the elastic compression and recovery of the elastic portion 702, at this time, the first elastic arm 7021 gradually breaks away from the compression of the contact portion 601, releases the elastic force to return to the initial state, and drives the abutting portion 603 to move in the direction opposite to the cover 303, and retracts into the accommodating space 3014 through the through hole 3015, so that the abutting portion 603 breaks away from the abutting against the electronic device, and the unlocking is achieved, as shown in fig. 10.
The connection relationship between the respective members related to the present application related to the seat cushion 100 in the present embodiment is specifically described above, but the assembly sequence of the plurality of members related to the latch structure 30 needs to be further described, and since the latch structure 30 is assembled as a whole and then connected to the base 10, the assembly of the members of the latch structure 30 will be mainly described below.
