DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Please refer to Figure 1 The present embodiment provides a linkage lock seat mechanism 100, including a seat body 110, and a seat cushion locking assembly 120 arranged on the seat body 110, the seat cushion locking assembly 120 is used to lock or unlock the seat cushion; the seat body 110 is also provided with a first locking assembly 130 and a second locking assembly 140, the first locking assembly 130 is used to connect to the first to-be-locked part through a first cable 150, and the second locking assembly 140 is used to connect to the second to-be-locked part through a second cable 160.

[0033] Specifically, in actual use, the seat body 110 of the present application is disposed in the storage box. Under normal conditions, the seat cushion disposed on the storage box is locked with the storage box through the seat cushion locking assembly 120. The seat cushion serves as a box cover and can be locked or unlocked with the storage box. When the seat cushion is locked with the storage box, since the seat body 110 is disposed in the storage box, the first locking assembly 130 and the second locking assembly 140 cannot be triggered, which is beneficial to improving the safety of the first and second locking parts to be locked. After the seat cushion is opened, the first locking assembly 130 and the second locking assembly 140 can be operated.

[0034] It should be noted that the embodiments of the present application do not impose any specific restrictions on the specific configuration of the first locking member and the second locking member, and are mainly applied to components on the vehicle body that require a lock-and-start function. For example, the first locking member may be a battery box cover lock, so that the first locking assembly 130 is triggered by connecting the first cable 150 to the first locking member. The second locking member may be a battery lock, so that the second locking assembly 140 is triggered by connecting the second cable 160 to the second locking member.

[0035] The linkage lock seat mechanism 100 provided in the embodiment of the present invention can lock or unlock the seat cushion through the seat cushion locking assembly 120 arranged on the seat body 110. At the same time, through the first locking assembly 130 on the seat body 110 and the first piece to be locked connected to the first locking assembly 130 through the first cable 150, the first locking assembly 130 can be manipulated to pull the first cable 150, thereby realizing the unlocking operation of the first piece to be locked. Through the second locking assembly 140 on the seat body 110 and the second piece to be locked connected to the second locking assembly 140 through the second cable 160, the second locking assembly 140 can be manipulated to pull the second cable 160, thereby realizing the unlocking operation of the second piece to be locked. With the above scheme, the seat cushion locking assembly 120, the first locking assembly 130 and the second locking assembly 140 can be integrated on the seat body 110, and when a vehicle model requiring more locking and starting functions is used, there is no need to install multiple lock seats, and there is no need to add other welding installation positions on the frame. By integrating multiple lock and unlock functions into one lock seat, assembly is simplified and convenient, thereby reducing manufacturing costs.

[0036] like Figure 1 and Figure 2 As shown, the seat locking assembly 120 includes a locking tongue 121, a seat locking rocker arm 122 and a locking tongue reset elastic member 123. The locking tongue 121 and the seat locking rocker arm 122 are respectively rotatably connected to the seat body 110. A limiting protrusion 1222 is provided on the seat locking rocker arm 122, and a groove 1212 is correspondingly provided on the locking tongue 121. The locking tongue reset elastic member 123 is respectively connected to the locking tongue 121 and the seat locking rocker arm 122 so that the limiting protrusion 1222 and the groove 1212 are engaged.

[0037] Specifically, the locking tongue 121 is used to cooperate with the hook on the seat cushion, and the seat cushion locking rocker arm 122 is provided with a seat cushion locking cable. When the seat cushion needs to be opened, the seat cushion locking rocker arm 122 is pulled by the seat cushion locking cable to unlock the locking tongue 121 and the hook on the seat cushion. The seat cushion locking rocker arm 122 and the locking tongue 121 have a first state of engagement and a second state of separation. In the initial state (the first state), under the action of the locking tongue resetting elastic member 123, the limiting protrusion 1222 on the seat cushion locking rocker arm 122 is engaged with the groove 1212 on the locking tongue 121 (such as Figure 1 When unlocking is required, the seat lock rocker arm 122 is rotated by pulling the seat lock cable, so that the position between the limiting protrusion 1222 and the groove 1212 moves relative to each other until the limiting protrusion 1222 and the groove 1212 are disengaged, that is, the locking relationship is broken. At this time, the second state (such as Figure 2 As shown in the figure, after the limiting protrusion 1222 is disengaged from the groove 1212, since the lock tongue reset elastic member 123 is respectively connected to the lock tongue 121 and the cushion locking rocker arm 122, the lock tongue 121 is rotated to a certain angle under the action of the lock tongue reset elastic member 123, so that the hook is separated from the restriction of the lock tongue 121 and the cushion is opened.

[0038] It should be noted that the embodiment of the present application does not impose any specific restrictions on the arrangement of the lock tongue reset elastic member 123, as long as it can provide the required elastic force. For example, the lock tongue reset elastic member 123 can be an elastic rope or a tension spring, or can be connected by a torsion spring, and the specific arrangement position can be flexibly set according to actual needs.

[0039] like Figure 3 As shown, the locking tongue 121 includes an arc-shaped notch 1213, and a first side wall 1214 and a second side wall 1215 forming the arc-shaped notch 1213. A guide groove 112 is correspondingly provided on the seat body 110 for enabling the hook on the seat cushion to engage with the arc-shaped notch 1213 when it is extended into the guide groove 112.

[0040] Specifically, when the hook on the seat extends from the guide groove 112, the hook abuts against the first side wall 1214, and under the action of the hook abutting force, the lock tongue 121 and the seat body 110 rotate relative to each other, so that the groove 1212 on the lock tongue 121 is engaged with the limiting protrusion 1222 on the seat locking rocker arm 122, and at the same time, the second side wall 1215 rotates to the guide groove 112, and the second side wall 1215 plays a limiting role on the hook, so that when the hook extends into the guide groove 112, it is engaged with the arc-shaped notch 1213, so that the lock tongue 121 locks the hook. When the hook needs to be unlocked, the seat locking rocker arm 122 is rotated by the seat lock cable, so that the groove 1212 on the lock tongue 121 is disengaged from the limiting protrusion 1222 on the seat locking rocker arm 122, and the lock tongue 121 rotates back under the action of the lock tongue reset elastic member 123 to release the restriction on the hook.

[0041] like Figure 4 As shown, the seat body 110 is further provided with a first protrusion 114 and a second protrusion 116 . The first protrusion 114 is used to limit the seat cushion locking rocker arm 122 , and the second protrusion 116 is used to limit the locking tongue 121 .

[0042] Specifically, the lock tongue reset elastic member 123 is connected to the lock tongue 121 and the cushion locking rocker arm 122 respectively. Under the force of the lock tongue reset elastic member 123, the lock tongue 121 and the cushion locking rocker arm 122 have a tendency to rotate relative to the seat body 110. In order to ensure the stability of the relative position of the lock tongue 121 and the cushion locking rocker arm 122 when the lock tongue 121 locks the hook, a first protrusion 114 is provided on the seat body 110 to limit the cushion locking rocker arm 122. Under the force of the lock tongue reset elastic member 123, the cushion locking rocker arm 122 abuts against the first protrusion 114. In order to ensure the stability of the relative position of the lock tongue 121 and the seat body 110 when the lock tongue 121 unlocks the hook, a second protrusion 116 is provided on the seat body 110 to limit the lock tongue 121. Under the force of the lock tongue reset elastic member 123, the lock tongue 121 abuts against the second protrusion 116. The above form is adopted to ensure the stability of the structure in the locked state and the unlocked state.

[0043] like Figure 5 As shown, the first locking assembly 130 includes a first rocker arm 131 and a first reset elastic member 133. The first rocker arm 131 is rotatably connected to the seat body 110. A first button 1312 is provided on the first rocker arm 131. The first reset elastic member 133 is respectively connected to the first rocker arm 131 and the seat body 110. A third protrusion 118 is also provided on the seat body 110 for limiting the first rocker arm 131.

[0044] Specifically, under the action of the first resetting elastic member 133, the first rocker arm 131 has a tendency to rotate relative to the seat body 110. In order to ensure the stability of the relative position of the first rocker arm 131 and the seat body 110, a third protrusion 118 is provided on the seat body 110 to limit the first rocker arm 131. Under the action of the first resetting elastic member 133, the first rocker arm 131 abuts against the third protrusion 118. When the first to-be-locked member needs to be unlocked by the first locking assembly 130, the first button 1312 is pressed to overcome the elastic force of the first resetting elastic member 133, so that the first rocker arm 131 rotates relative to the seat body 110, thereby pulling the first cable 150 to unlock the first to-be-locked member.

[0045] It should be noted that the embodiment of the present application does not impose any specific restrictions on the arrangement of the first resetting elastic member 133, as long as it can provide the required elastic force. For example, the first resetting elastic member 133 can be an elastic rope or a tension spring, or can be connected by a torsion spring, and the specific arrangement position can be flexibly set according to actual needs.

[0046] like Figure 3 and Figure 5 As shown, a limiting portion 1216 is further provided on the locking tongue 121 , and a clamping portion 1314 is correspondingly provided on the first rocker arm 131 , and the limiting portion 1216 can be clamped with the clamping portion 1314 .

[0047] Specifically, the seat body 110 is arranged in the storage box. When the first button 1312 needs to be pressed, the seat cushion needs to be opened first. When the seat cushion is opened, the lock tongue 121 rotates relative to the seat body 110 under the action of the lock tongue reset elastic member 123 until the lock tongue 121 abuts against the second protrusion 116. At this time, when the first button 1312 is pressed, the first rocker arm 131 rotates relative to the seat body 110, thereby pulling the first cable 150 to unlock the first to-be-locked part. When the first button 1312 is released, the first rocker arm 131 rotates back under the elastic force of the first reset elastic member 133 until the clamping portion 1314 abuts against and clamps with the limiting portion 1216 to ensure the opening state of the first to-be-locked part. When the seat cushion is closed, the lock tongue 121 rotates back to the first state where there is a clamping connection between the seat cushion locking rocker arm 122 and the lock tongue 121. At this time, the limiting portion 1216 of the locking tongue 121 releases the limiting action on the clamping portion 1314 of the first rocker arm 131, so that the first rocker arm 131 rotates to the locked position under the action of the first reset elastic member 133, so as to achieve simultaneous locking of the seat cushion and the first member to be locked.

[0048] like Figure 6As shown, a first positioning hole 1316 is provided on the first rocker arm 131 , a first opening 1318 is provided on a side wall forming the first positioning hole 1316 , and a first limiting portion 1319 is further provided on the first rocker arm 131 , with a gap between the first limiting portion 1319 and the first opening 1318 .

[0049] Specifically, the first cable 150 is connected to the first to-be-locked member through the first rocker arm 131, and one end of the first cable 150 is inserted into the first positioning hole 1316. When the first cable 150 and the first rocker arm 131 are installed in coordination, the first cable 150 slides from the first opening 1318 into the first positioning hole 1316, and is engaged with the first rocker arm 131 to form a connection and coordination relationship. The gap between the first limiting portion 1319 and the first opening 1318 facilitates the first cable 150 to slide into the first opening 1318. After the engagement is completed, the first limiting portion 1319 can prevent the first cable 150 from being loosened from the first rocker arm 131, which is conducive to improving the stability of the connection.

[0050] like Figure 1 and Figure 7 As shown, the second locking assembly 140 includes a second rocker arm 141 and a second reset elastic member 143. The second rocker arm 141 is rotatably connected to the seat body 110. A second button 1412 is provided on the second rocker arm 141. The second reset elastic member 143 is respectively connected to the second rocker arm 141 and the seat body 110. A fourth protrusion 119 is also provided on the seat body 110 for limiting the second rocker arm 141.

[0051] Specifically, under the action of the second resetting elastic member 143, the second rocker arm 141 has a tendency to rotate relative to the seat body 110. In order to ensure the stability of the relative position of the second rocker arm 141 and the seat body 110, a fourth protrusion 119 is provided on the seat body 110 to limit the second rocker arm 141. Under the action of the second resetting elastic member 143, the second rocker arm 141 abuts against the fourth protrusion 119. When the second locking member 140 needs to be unlocked, the second button 1412 is pressed to overcome the elastic force of the second resetting elastic member 143, so that the second rocker arm 141 rotates relative to the seat body 110, thereby pulling the second cable 160 to unlock the second locking member.

[0052] It should be noted that the embodiment of the present application does not impose any specific restrictions on the arrangement of the second reset elastic member 143, as long as it can provide the required elastic force. For example, the second reset elastic member 143 can be an elastic rope or a tension spring, or can be connected by a torsion spring, and the specific arrangement position can be flexibly set according to actual needs.

[0053] like Figure 8As shown, a second positioning hole 1416 is provided on the second rocker arm 141 , a second opening 1418 is provided on a side wall forming the second positioning hole 1416 , and a second limiting portion 1419 is further provided on the second rocker arm 141 , with a gap between the second limiting portion 1419 and the second opening 1418 .

[0054] Specifically, the second cable 160 is connected to the second locking member through the second rocker arm 141, and one end of the second cable 160 is inserted into the second positioning hole 1416. When the second cable 160 and the second rocker arm 141 are installed in coordination, the second cable 160 slides from the second opening 1418 into the second positioning hole 1416, and is engaged with the second rocker arm 141 to form a connection and coordination relationship. The gap between the second limiting portion 1419 and the second opening 1418 facilitates the second cable 160 to slide into the second opening 1418. After the engagement is completed, the second limiting portion 1419 can prevent the second cable 160 from loosening from the second rocker arm 141, which is conducive to improving the stability of the connection.

[0055] It should be noted that the embodiment of the present application does not specifically limit the number of the first positioning hole 1316 or the second positioning hole 1416, and can be flexibly set according to actual needs to ensure the needs of the multi-locking function. For example, the first positioning hole 1316 can be set to one or two, and the first cable 150 is connected to the first positioning hole 1316. The second positioning hole 1416 can also be set to one or two, and the second cable 160 is connected to the second positioning hole 1416.
