Description

Technical Field

[0001] The present invention relates to the technical field of locks, and particularly to a saddle lock. Background Art

[0002] Motorcycles and battery-powered vehicles are commonly used means of transportation in people's daily lives. Below the seat (saddle) of motorcycles and battery-powered vehicles, a storage cavity is generally provided for users to place objects. To improve safety, a locking hook of a saddle lock is used to lock with a lock buckle on the seat cushion.

[0003] In the natural state, the locking hook of the saddle lock is located at the locking position. When unlocking, it is generally achieved by rotation. When unlocking is required, an artificial remote controller needs to be used to drive the locking hook of the saddle lock to rotate away from the lock buckle to achieve unlocking. After unlocking, the saddle lock can rotate reversely to reset, so that the locking hook rotates to the locking position. When the side of a motorcycle or a battery-powered vehicle is impacted in the unlocking direction, under the action of inertia, the saddle lock will rotate, and then disengage from the lock buckle, resulting in the unlocking of the locked state, and further causing the items in the storage cavity to spill or be lost.

[0004] Therefore, there is an urgent need to design a technical solution that can prevent the saddle lock from automatically unlocking due to inertia when the vehicle body is impacted. Summary of the Invention

One side of the upper part of the locking ratchet is connected to the upper part of the locking hook through an elastic member, and the lower part of the locking ratchet is rotatably arranged on the locking plate assembly through a second rotating shaft; when the locking ratchet rotates, it can drive the locking hook to rotate around the first rotating shaft and disengage from the lock catch to achieve unlocking; the shock-resistant mechanism is located on the side of the lower part of the locking ratchet close to the opening of the hook body, and under inertial force, the shock-resistant mechanism can abut against the side of the lower part of the locking ratchet close to the opening of the hook body.

[0015] Preferably, the shock-resistant mechanism includes a counterweight. One side of the counterweight is connected to the locking plate assembly through the elastic member, and the other side of the counterweight can abut against the side of the hook body far from the opening or abut against the side of the lower part of the locking ratchet close to the opening of the hook body.

[0016] Preferably, a first convex tooth is provided on the side of the locking ratchet close to the locking hook. A concave first sliding groove is connected below the first convex tooth. A second convex tooth is provided at the position of the locking hook close to the first convex tooth. A smooth first tooth groove is connected below the second convex tooth; when the locking hook is in the locked state, the first convex tooth can be engaged with the first tooth groove; during the unlocking process of the locking hook, the second convex tooth can slide downward to the position of the first sliding groove.

[0021] Compared with the prior art, the present invention has achieved the following technical effects:

[0022] The saddle lock is in a locked state. When the saddle lock is subjected to an impact force in the unlocking direction and the vehicle body overturns, under the action of inertia and gravity, the upper part of the lock hook will rotate around the hinge point toward one side of the impact direction, and the lower part of the lock hook is located below the hinge point. During the process, the lower part of the lock hook will rotate to the side away from the impact direction, thereby causing the lower part of the lock hook and the lock buckle to be unlocked in an abnormal state; the present invention provides an anti-impact mechanism on the lock plate assembly. Normally, the anti-impact mechanism does not contact the lock hook and other components, so it will not hinder the normal unlocking of the lock hook. 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 implementation manners

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] The purpose of the present invention is to provide a saddle lock to solve the problems existing in the above-mentioned prior art, and to avoid the automatic unlocking of the saddle lock due to inertia when the vehicle body is impacted.

[0030] To make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0031] When the saddle lock is in the locked state, when one side of the vehicle body is impacted 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 towards the side close to the impact direction, and then rotate towards the unlocking direction around the hinge point. 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 towards the side away from the impact direction, thereby causing the lower part of the lock hook and the latch to be unlocked under abnormal conditions.

[0032] 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 buckle 1, a lock plate assembly 2, a lock hook 5 assembly and an anti-impact mechanism. The 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. For the convenience of locking, the bottom of the lock hook 5 in this embodiment is provided with a hook body, the outer bottom of the hook body is a smooth inclined surface structure, and the front side of the hook body is open. The buckle 1 includes a mounting plate fixedly arranged on the saddle, and a U-shaped rod is connected to the mounting plate. When the saddle rotates 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 fits the frame. When the unlocker is controlled by a remote control to drive the lower part of the lock hook 5 to rotate backward, the hook body can disengage from the buckle 1 at 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 move forward against the elastic force of the elastic member under the inertial force, 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 elastic force of the elastic member, the anti-impact mechanism moves to the side away from the impact direction to the initial position and does not interfere with the normal unlocking process of the lock hook 5; thus, the present invention can avoid the automatic unlocking of the saddle lock due to inertia when the vehicle body is impacted.

[0033] In one embodiment, the anti-impact mechanism is located on the side away from the opening of the hook body. Thus, in this embodiment, when the unlocker is controlled by a remote control to drive the lower part of the lock hook 5 to rotate in the unlocking direction, the hook body can disengage from the buckle 1 at the open end to achieve unlocking. During the process, the anti-impact mechanism remains stationary and thus does not interfere with this unlocking process. When an impact occurs in the unlocking direction, the upper part of the lock hook 5 rotates to the side close to the impact direction under the inertial force, and further causes the hook body at the bottom of the lock hook 5 to rotate to the side away from the impact direction. At this time, under the inertial force, the anti-impact mechanism also moves to the side close to the impact direction, and then the anti-impact mechanism can abut against the side of the hook body away from the opening, restricting the tendency of the hook body to move to the side away from the impact direction, so that the hook body cannot move to the side away from the impact direction, avoiding the unlocking of the hook body in an abnormal state. When the impact disappears, the anti-impact mechanism moves to the side away from the impact direction to the initial position under the restoring force of the elastic member and does not interfere 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 can be used, etc. In this embodiment, a compression spring 8 is used as the elastic member.

[0034] To achieve rapid unlocking under normal conditions, in one embodiment, the lock hook 5 assembly further includes a lock ratchet 3. One side of the upper part of the lock ratchet 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 can be a spring, a telescopic rod, etc. In this embodiment, the elastic member is a tension spring 4. The opening on one side of the upper part of the lock ratchet 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 ratchet 3 is rotatably arranged on the lock plate of the lock plate assembly 2 through a second rotating shaft. When the lock ratchet 3 rotates, it can drive the lock hook 5 to rotate around the first rotating shaft and disengage from the lock catch 1 to achieve unlocking. The top of the lock ratchet 3 is provided with an unlocking dial 302. The unlocker can abut against the unlocking dial 302 and then drive the unlocking dial 302 to rotate around the second rotating shaft. During this process, the lock ratchet 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 at the lower part of the lock hook 5 to rotate backward synchronously, that is, to rotate toward the side away from the impact direction, to disengage from the lock catch 1 and achieve unlocking. The unlocker in this embodiment is a known structure, which uses a motor and a gear set structure to drive the slider to move reciprocally. During the movement of the slider, it can abut against the unlocking dial 302 and then drive the unlocking dial 302 to rotate around the second rotating shaft.

[0035] In another embodiment, a cable connecting block 303 is provided on the side of the top of the lock ratchet 3 away from the tension spring 4. The cable connecting block 303 is fixedly connected to one end of a cable, and the other end of the cable is connected to the slider of the unlocker. Thus, the unlocker can also drive the upper part of the lock ratchet 3 to rotate around the second rotating shaft through the cable and finally achieve the unlocking process.

[0036] Due to the introduction of the lock ratchet 3 structure, the position of the anti-impact mechanism in this embodiment has changed. The anti-impact mechanism in this embodiment is located on the side of the lock ratchet 3 below and close to the opening of the hook body, that is, on the side below the second rotating shaft. In this embodiment, when the unlocker is controlled by a remote control to drive the upper part of the lock ratchet 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 disengage from the lock catch 1 at the opening end to achieve unlocking. During this process, the anti-impact mechanism remains stationary and thus does not interfere with this unlocking process. When an impact occurs in the unlocking direction, the upper part of the lock ratchet 3 rotates forward under the action of inertia and gravity, and then the part of the lock ratchet 3 below the second rotating shaft rotates backward. At this time, under inertia, the anti-impact mechanism also moves forward, and then the anti-impact mechanism can abut against the part of the lock ratchet 3 below the second rotating shaft to limit the tendency of the lock ratchet 3 to move backward, so that the upper part of the lock ratchet 3 cannot move forward, and thus the upper part of the lock hook 5 cannot move forward, avoiding unlocking of the hook body under abnormal conditions. When the impact disappears, the anti-impact mechanism moves backward to the initial position under the restoring force of the compression spring 8 and does not interfere with the normal rotational unlocking process of the lock ratchet 3.

[0037] When an impact in the unlocking direction occurs, the abnormal state unlocking process of the locking hook 5 is very rapid. In order to avoid this process in a timely manner, the anti-impact mechanism of this embodiment is designed to include a counterweight 7. The counterweight 7 has a large weight, so the inertial force is large. One side of the counterweight 7 of this embodiment is connected to the lock plate assembly 2 through a compression spring 8, and the other side of the counterweight 7 can abut against one side of the lower part of the lock pawl 3 close to the opening of the hook body. When an impact in the unlocking direction occurs, under the action of inertial force and gravity, the counterweight 7 can move forward rapidly to achieve the limiting effect on the lower part of the lock pawl 3.

[0038] When the counterweight 7 is directly slidably arranged on one side of the lock plate, it is impossible to limit the counterweight 7, resulting in the deviation of the counterweight 7. In order to avoid this problem, in one embodiment, a strip-shaped groove 9 is formed on the lock plate assembly 2, and the counterweight 7 is movably arranged in the strip-shaped groove 9. The strip-shaped groove 9 limits the counterweight 7, so that the counterweight 7 can only slide back and forth along the strip-shaped groove 9 and will not shake up and down; one side of the counterweight 7 is connected to the inner wall of one end of the strip-shaped groove 9 through a tension spring 4. Since the counterweight 7 is arranged in the strip-shaped groove 9, it cannot directly abut against one side of the lower part of the lock pawl 3. In order not to affect the anti-impact effect of the counterweight 7 on the lock pawl 3, in this embodiment, a stop rod 6 is fixedly arranged on the counterweight 7, and the end of the stop rod 6 extends out of the strip-shaped groove 9, and the part of the stop rod 6 located outside the strip-shaped groove 9 can abut against one side of the lower part of the lock pawl 3 close to the opening of the hook body, and the anti-impact limit of the lock pawl 3 can be realized through the baffle. In a preferred embodiment, in order to further make the forward and backward movement process of the counterweight 7 more accurate, a guide rod is fixedly connected to one side of the counterweight 7. The guide rod movably penetrates through one end of the strip-shaped groove 9, and the tension spring 4 is coaxial with the guide rod. When the counterweight 7 moves back and forth in the strip-shaped groove 9, the guide rod moves back and forth in the opening at one end of the strip-shaped groove 9, realizing further limitation of the counterweight 7, and the compression spring 8 is sleeved on the guide rod, so that the compression spring 8 will not bend during the stretching process, and a certain limiting effect on the compression spring 8 is also achieved.

[0039] In order to avoid relative sliding when the baffle abuts against the lock pawl 3, thereby reducing the limiting effect of the stop rod 6 on the lower part of the lock pawl 3, in one embodiment, a smooth card slot 304 is provided on one side of the lower part of the lock pawl 3 close to the opening of the hook body. The part of the stop rod 6 located outside the strip-shaped groove 9 can abut against the side of the hook body far from the opening or against the card slot 304, so that when an impact in the unlocking direction occurs, the stop rod 6 can quickly enter the card slot 304 to realize the limitation of the lock pawl 3.

[0040] In order to clarify the locking position, in one embodiment, a first convex tooth 301 is provided on one side of the lock pawl 3 close to the lock hook 5. A concave first chute is connected below the first convex tooth 301. A second convex tooth is provided at a position of the lock hook 5 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 be engaged 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 chute. When closing the saddle downward, the lock buckle 1 is snapped into the hook body of the lock hook 5. Due to the pulling force of the tension spring 4, the upper part of the lock hook 5 rotates synchronously with the lock pawl 3, so that the position of the first convex tooth 301 of the lock pawl 3 is engaged with the position of the first tooth groove 501 of the lock hook 5 to achieve the locking operation. When unlocking, the position of the first convex tooth 301 of the lock pawl 3 is disengaged from the position of the first tooth groove 501 of the lock hook 5. At this time, the second convex tooth can slide downward to the position of the first chute. At this time, the hook body of the lock hook 5 rotates backward to disengage from the lock buckle 1 to achieve unlocking.

[0041] In the present invention, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. At the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation of the present invention.
