Description

Technical Field

[0001] The invention relates to the technical field of locks, in particular to a saddle lock. Background Art

[0002] Motorcycles and electric vehicles are commonly used means of transportation in people's daily lives. Under the seat cushion (saddle) of motorcycles and electric vehicles, there is generally a storage cavity for users to place objects. In order to improve safety, the saddle lock is locked by a lock hook of the saddle lock and a lock buckle on the seat cushion.

[0003] The lock hook of the saddle lock is in the locked position in its natural state. When unlocking, it is usually achieved by rotating the lock buckle. When unlocking is required, the unlocker needs to be manually controlled remotely so that the unlocker drives the lock hook of the saddle lock to rotate to disengage from the lock buckle, thereby achieving unlocking. After unlocking, the saddle lock can be reversed and reset to make the lock hook rotate to the locked position. When the side of a motorcycle or electric vehicle is subjected to an impact force in the unlocking direction, the saddle lock will rotate under the action of inertia and then disengage from the lock buckle, so that the locked state is released, which in turn causes the items in the storage cavity to spill or be lost.

When subjected to an impact force in the unlocking direction, the lock hook will be unlocked normally. When an impact force occurs, the anti-impact mechanism quickly moves toward one side of the impact direction under the action of inertia and gravity, which is opposite to the moving direction of the lower part of the lock hook, and abuts against the lower part of the lock hook assembly, thereby offsetting the force of the lock hook moving toward the side away from the impact direction, so that the lower part of the lock hook cannot be rotated toward the side away from the impact direction to unlock; when the impact force disappears, under the elastic force of the elastic member, the anti-impact mechanism moves to the initial position and will not interfere with the normal unlocking process of the lock hook; thereby, the present invention can prevent the saddle lock from being automatically unlocked due to inertia when the vehicle body is subjected to an impact force.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0021] The object of the present invention is to provide a saddle lock to solve the problems existing in the above-mentioned prior art and to prevent the saddle lock from being automatically unlocked due to inertia when the vehicle body is subjected to impact force.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] The saddle lock is in the locked state. When one side of the vehicle body is subjected to an impact force in the unlocking direction, or the vehicle body overturns, under the action of inertia and gravity, the upper part of the lock hook will move toward the side close to the impact direction, and then rotate around the hinge point in the unlocking direction. The lower part of the lock hook is located below the hinge point. During this process, the lower part of the lock hook will rotate toward the side away from the impact direction, causing the lower part of the lock hook and the lock buckle to be unlocked in an abnormal state.

[0024] In order to solve the above technical problems, the present invention provides a saddle lock, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a lock buckle 1, a lock plate assembly 2, a lock hook 5 assembly and an anti-impact mechanism. The lock buckle 1 is fixedly installed on the saddle; the lock plate assembly 2 includes a lock plate bracket and a lock plate, and the lock plate is fixedly installed on the frame through the lock plate bracket; the lock hook 5 assembly includes a lock hook 5 rotatably arranged on the lock plate assembly 2. In order to facilitate locking, a hook body is provided at the bottom of the lock hook 5 of this embodiment. The bottom of the hook body is a smooth inclined structure, and the front side of the hook body is open. The lock buckle 1 includes a mounting plate, which is fixedly arranged on the saddle. A U-shaped rod is connected to the mounting plate. When the saddle is rotated downward, the end of the U-shaped rod away from the mounting plate can gradually slide into the opening of the hook body along the inclined surface of the hook body to achieve locking. At this time, the saddle is close to the When the unlocker is controlled by the remote control to drive the lower part of the lock hook 5 to rotate backward, the hook body can be separated from the lock buckle 1 from the open end to achieve unlocking; the anti-impact mechanism is connected to the lock plate assembly 2 through an elastic member. When the vehicle body is impacted, the anti-impact mechanism can overcome the elastic force of the elastic member under the inertia force and move forward, abut against one side of the lower part of the lock hook 5 assembly, and limit the rotation of the lower part of the lock hook 5 to the side away from the impact direction; when the impact force disappears, under the action of the elastic force of the elastic member, the anti-impact mechanism moves to the initial position to the side away from the impact direction, and will not interfere with the normal unlocking process of the lock hook 5; thereby, the present invention can prevent the saddle lock from being automatically unlocked due to inertia when the vehicle body is subjected to impact force.

[0025] In one embodiment, the anti-impact mechanism is located on the side away from the opening of the hook body. In this embodiment, when the unlocker is controlled by the remote control to drive the lower part of the lock hook 5 to rotate in the unlocking direction, the hook body can be separated from the lock buckle 1 from the opening end to achieve unlocking. During the process, the anti-impact mechanism is fixed and does not interfere with the unlocking process. When an impact in the unlocking direction occurs, the upper part of the lock hook 5 rotates toward the side close to the impact direction under the action of inertia, thereby causing the hook body at the bottom of the lock hook 5 to rotate toward the side away from the impact direction. At this time, under the inertia, the anti-impact mechanism also moves toward the side close to the impact direction, thereby the anti-impact mechanism can abut against the side of the hook body away from the opening, limiting the tendency of the hook body to move toward the side away from the impact direction, so that the hook body cannot move toward the side away from the impact direction, thereby avoiding unlocking of the hook body in an abnormal state. When the impact disappears, the anti-impact mechanism moves to the initial position toward the side away from the impact direction under the action of the restoring force of the elastic member, thereby not interfering with the normal unlocking process of the lock hook 5. The elastic member of the present invention is not limited. In one embodiment, a telescopic rod or a cylinder or the like can be used. In this embodiment, a compression spring 8 is used as the elastic member.

[0026] In order to achieve rapid unlocking in the normal state, in one embodiment, the lock hook 5 assembly also includes a lock pawl 3, one side of the upper part of the lock pawl 3 is connected to the upper part of the lock hook 5 through an elastic member, the specific structure of the elastic member is not limited, and a spring, a telescopic rod, etc. can be used. The elastic member of this embodiment adopts a tension spring 4; the opening on one side of the upper part of the lock pawl 3 is fixedly connected to the opening on the upper part of the lock hook 5 through the tension spring 4; the lower part of the lock pawl 3 is rotatably arranged on the lock plate of the lock plate assembly 2 through the second rotating shaft; when the lock pawl 3 rotates, it can drive the lock hook 5 to rotate around the first rotating shaft and disengage from the lock buckle 1 to achieve unlocking; the top of the lock pawl 3 is provided with a release The lock lever block 302, the unlocking device can abut against the unlocking lever block 302, and then drive the unlocking lever block 302 to rotate around the second rotation axis. During the process, the lock pawl 3 drives the upper part of the lock hook 5 to rotate forward through the tension spring 4, that is, to rotate toward the side close to the impact direction, and then drives the hook body of the lower part of the lock hook 5 to rotate backward synchronously, that is, to rotate toward the side away from the impact direction, disengage from the lock buckle 1, and realize unlocking. The unlocking device of this embodiment is a known structure, which adopts a motor and a gear set structure to drive the slider to move back and forth. During the movement of the slider, it can abut against the unlocking lever block 302, and then drive the unlocking lever block 302 to rotate around the second rotation axis.

[0027] In another embodiment, a cable connecting block 303 is provided on the side of the top of the lock pawl 3 away from the tension spring 4. The cable connecting block 303 is fixedly connected to one end of the cable, and the other end of the cable is connected to the slider of the unlocker. Then, the unlocker can also drive the upper part of the lock pawl 3 to rotate around the second rotating axis through the cable, and finally realize the unlocking process.

[0028] Due to the introduction of the locking pawl 3 structure, the position of the anti-impact mechanism of this embodiment is changed. The anti-impact mechanism of this embodiment is located on the side below the locking pawl 3 close to the hook opening, that is, on the side below the second rotating shaft. When the unlocking device is controlled by the remote control to drive the upper part of the lock pawl 3 to rotate forward and drive the upper part of the lock hook 5 to rotate forward synchronously, the lower part of the lock hook 5 rotates backward, and the hook body can be separated from the lock buckle 1 from the open end to achieve unlocking. During the process, the anti-shock mechanism is fixed and does not interfere with the unlocking process. When an impact in the unlocking direction occurs, the upper part of the lock pawl 3 rotates forward under the action of inertia and gravity, and then the part of the lock pawl 3 located below the second rotating shaft rotates backward. At this time, under the inertia, the anti-shock mechanism also moves forward, and then the anti-shock mechanism can abut against the part of the lock pawl 3 located below the second rotating shaft, limiting the tendency of the lock pawl 3 to move backward, making the upper part of the lock pawl 3 unable to move forward, and then making the upper part of the lock hook 5 unable to move forward, avoiding unlocking of the hook body in an abnormal state. When the impact disappears, the anti-shock mechanism moves backward to the initial position under the action of the restoring force of the compression spring 8, and will not interfere with the normal rotation and unlocking process of the lock pawl 3.

[0029] When an impact in the unlocking direction occurs, the abnormal state unlocking process of the lock hook 5 is very rapid. In order to avoid this process in time, the anti-impact mechanism of this embodiment is designed to include a counterweight block 7. The weight of the counterweight block 7 is large, so the inertia force is large. One side of the counterweight block 7 of this embodiment is connected to the lock plate assembly 2 through a compression spring 8, and the other side of the counterweight block 7 can abut against the side of the lower part of the lock pawl 3 close to the hook body opening. When an impact in the unlocking direction occurs, under the action of inertia and gravity, the counterweight block 7 can move forward quickly to achieve a limiting effect on the lower part of the lock pawl 3.

[0030] When the counterweight block 7 is directly slidably arranged on one side of the lock plate, it is impossible to limit the counterweight block 7, causing the counterweight block 7 to deviate. In order to avoid this problem, in one embodiment, a strip groove 9 is opened on the lock plate assembly 2, and the counterweight block 7 is movably arranged in the strip groove 9. The counterweight block 7 is limited by the strip groove 9, so that the counterweight block 7 can only slide back and forth along the strip groove 9, and will not shake up and down; one side of the counterweight block 7 is connected to the inner wall of one end of the strip groove 9 by the tension spring 4. Since the counterweight block 7 is arranged in the strip groove 9, it cannot directly abut against one side of the lower part of the locking pawl 3. In order not to affect the anti-impact effect of the counterweight block 7 on the locking pawl 3, in this embodiment, a blocking rod 6 is fixedly provided on the counterweight block 7, and the end of the blocking rod 6 extends out of the strip groove 9, and the part of the blocking rod 6 located outside the strip groove 9 can abut against one side of the lower part of the locking pawl 3 close to the hook body opening, and the anti-impact limiting of the locking pawl 3 can be achieved through the baffle. In a preferred embodiment, in order to further make the counterweight block 7 move back and forth more accurately, a guide rod is fixedly connected to one side of the counterweight block 7, and the guide rod is movably inserted into one end of the strip groove 9. The tension spring 4 is coaxial with the guide rod. When the counterweight block 7 moves back and forth in the strip groove 9, the guide rod moves back and forth in the opening at one end of the strip groove 9, thereby further limiting the counterweight block 7. The compression spring 8 is mounted on the guide rod, so that the compression spring 8 will not bend during the extension and retraction process, and it also plays a certain limiting role on the compression spring 8.

[0031] In order to avoid relative sliding when the baffle plate and the lock pawl 3 abut against each other, thereby reducing the limiting effect of the baffle rod 6 on the lower part of the lock pawl 3, in one embodiment, a smooth slot 304 is provided on the lower part of the lock pawl 3 close to the opening of the hook body, and the portion of the baffle rod 6 located outside the strip groove 9 can abut against the side of the hook body away from the opening or against the slot 304, so that when an impact in the unlocking direction occurs, the baffle rod 6 can quickly enter the slot 304 to limit the lock pawl 3.

[0032] In order to make the locking position clear, in one embodiment, the locking pawl 3 is provided with a first convex tooth 301 on the side close to the lock hook 5, and a concave first slide groove is connected below the first convex tooth 301. The lock hook 5 is provided with a second convex tooth at a position close to the first convex tooth 301, and a smooth first tooth groove 501 is connected below the second convex tooth; when the lock hook 5 is in the locked state, the first convex tooth 301 can mesh with the first tooth groove 501; during the unlocking process of the lock hook 5, the second convex tooth can slide downward to the position of the first slide groove. When the saddle is closed downward, the lock buckle 1 is inserted into the hook body of the lock hook 5, and the upper part of the lock hook 5 rotates synchronously with the locking pawl 3 due to the tension of the tension spring 4, so that the first convex tooth 301 position of the lock pawl 3 is meshed with the first tooth groove 501 position of the lock hook 5, and the locking operation is realized. When unlocking, the first convex tooth 301 position of the lock pawl 3 is out of meshing with the first tooth groove 501 position of the lock hook 5. At this time, the second convex tooth can slide downward to the first slide groove position. At this time, the hook body of the lock hook 5 rotates backward to disengage the lock buckle 1 to achieve unlocking.

[0033] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
