The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1, the present embodiment provides a linkage seat locking mechanism 100, which includes a seat body 110 and a seat cushion locking assembly 120 disposed on the seat body 110, wherein the seat cushion locking assembly 120 is used for locking or unlocking the seat cushion; the base 110 is further provided with a first locking assembly 130 and a second locking assembly 140, the first locking assembly 130 is used for being connected with a first to-be-locked part through a first cable 150, and the second locking assembly 140 is used for being connected with a second to-be-locked part through a second cable 160.

Specifically, when in actual use, the pedestal 110 of this application sets up in putting the thing box, and under the normal condition, the cushion that puts the thing box and go up the setting passes through cushion locking subassembly 120 and puts and be in the locking state between the thing box. The cushion is used as a box cover and can be locked with or unlocked from the object placing box body. When the cushion with put between the thing box locking, because pedestal 110 sets up in putting the thing box for first locking subassembly 130 and second locking subassembly 140 can not triggered, be favorable to promoting the first security that waits the latch fitting with the second and wait the latch fitting, open the back at the cushion, can operate first locking subassembly 130 and second locking subassembly 140.

It should be noted that, the embodiment of the present application does not specifically limit the specific arrangement forms of the first to-be-locked component and the second to-be-locked component, and is mainly applied to components that need a locking and unlocking function on a vehicle body. For example, the first to-be-locked member may be a battery cover lock, such that the first locking assembly 130 is triggered by the connection of the first cable 150 with the first to-be-locked member. The second waiting to-be-locked part may be a battery lock such that the second locking assembly 140 is triggered by the connection of the second cable 160 with the second waiting to-be-locked part.

The linkage seat locking mechanism 100 provided by the embodiment of the invention can lock or unlock the seat cushion through the seat cushion locking assembly 120 arranged on the seat body 110. Meanwhile, through the first locking component 130 on the base 110 and the first to-be-locked component connected with the first locking component 130 through the first cable 150, the first locking component 130 can be controlled to pull the first cable 150, so as to realize the unlocking operation of the first to-be-locked component. Through the second locking subassembly 140 on the pedestal 110 to and wait the latch fitting through the second that second cable 160 is connected with second locking subassembly 140, the accessible is controlled second locking subassembly 140 in order to stimulate second cable 160, thereby realizes waiting the unblock operation of latch fitting to the second. Adopt above-mentioned scheme, can be integrated on pedestal 110 with cushion locking subassembly 120, first locking subassembly 130 and second locking subassembly 140, need not to install a plurality of locks seats when the motorcycle type that the more lock of demand opened the function uses, need not to increase other welding installation positions on the frame. Through the form of integrating the function that opens many locks on a lock seat, make the assembly simple and convenient, and then reduce manufacturing cost.

As shown in fig. 1 and 2, the seat cushion latch assembly 120 includes a latch tongue 121, a seat cushion latch rocker 122 and a latch tongue return elastic element 123, the latch tongue 121 and the seat cushion latch rocker 122 are respectively rotatably connected to the seat body 110, a limit protrusion 1222 is disposed on the seat cushion latch rocker 122, a groove 1212 is correspondingly disposed on the latch tongue 121, and the latch tongue return elastic element 123 is respectively connected to the latch tongue 121 and the seat cushion latch rocker 122, so that the limit protrusion 1222 and the groove 1212 are engaged.

Specifically, spring bolt 121 is used for cooperating with the couple on the cushion, is provided with cushion lock cable on the cushion locking rocking arm 122, when the cushion is opened to needs, through cushion lock cable pulling cushion locking rocking arm 122 to make the couple unblock on spring bolt 121 and the cushion. Wherein, have the first state of joint and the second state of separation between cushion locking rocking arm 122 and the spring bolt 121, under initial condition (under the first state), under the effect of spring bolt reset elastic component 123, spacing arch 1222 on cushion locking rocking arm 122 and the recess 1212 joint (as the state in fig. 1) on the spring bolt 121, when needs unblock, through cushion lock cable pulling cushion locking rocking arm 122 rotation, make the position between spacing arch 1222 and the recess 1212 take place relative motion, until the dropout is between spacing arch 1222 and the recess 1212, break away from the joint relation promptly. At this time, a second state (as shown in fig. 2) is formed between the cushion latch rocker 122 and the latch tongue 121, after the limit protrusion 1222 is disengaged from the groove 1212, because the latch tongue reset elastic element 123 is connected to the latch tongue 121 and the cushion latch rocker 122 respectively, under the action of the latch tongue reset elastic element 123, the latch tongue 121 rotates by a certain angle, so that the hook is disengaged from the limit of the latch tongue 121, and the opening of the cushion is realized.

It should be noted that, in the embodiment of the present application, the arrangement form of the latch return elastic member 123 is not particularly limited as long as the required elastic force can be provided. In the example, the bolt resetting elastic element 123 may be an elastic rope or an extension spring, or may be connected by a torsion spring, and the specific setting position may be flexibly set according to actual needs.

As shown in fig. 3, the latch tongue 121 includes an arc notch 1213, and a first side wall 1214 and a second side wall 1215 forming the arc notch 1213, and the seat body 110 is correspondingly provided with a guide slot 112 for engaging with the arc notch 1213 when the hook on the seat cushion extends into the guide slot 112.

Specifically, when the hook on the seat cushion extends from the guide groove 112, the hook abuts against the first side wall 1214, under the action of the abutting force of the hook, the lock tongue 121 and the seat body 110 are relatively rotated, so that the groove 1212 on the lock tongue 121 is clamped with the limiting protrusion 1222 on the seat cushion locking rocker arm 122, meanwhile, the second side wall 1215 is rotated to the guide groove 112, the second side wall 1215 plays a limiting role on the hook, the hook extends into the guide groove 112 and is clamped with the arc notch 1213, and the locking effect of the lock tongue 121 on the hook is realized. When the hook needs to be unlocked, the cushion locking rocker arm 122 is rotated through the cushion locking cable, so that the groove 1212 on the latch bolt 121 is disengaged from the limit protrusion 1222 on the cushion locking rocker arm 122, and the latch bolt 121 rotates back under the action of the latch bolt resetting elastic element 123 to release the limitation on the hook.
