Abstract
Description
Technical Field
[0001] This disclosure relates to the field of vehicle lock technology, and in particular to a locking actuator, a locking module, and a vehicle lock. Background Technology
[0002] Shared bicycles are generally equipped with smart locks, allowing users to unlock them remotely via mobile devices.
[0003] Early products mostly used exposed horseshoe locks, with the locking ring directly engaging the wheel spokes. Because the locking ring was exposed, it was extremely vulnerable to violent damage such as shearing and prying, leading to frequent incidents of vehicle damage and loss.
[0004] Subsequently, the mainstream solution in the industry was upgraded to a built-in brake disc lock, where the brake disc rotates coaxially with the wheel hub, and the locking module is hidden inside the housing. Locking is achieved by embedding a locking component into the brake disc. This design significantly increases the difficulty of brute-force attacks, resulting in a substantial decrease in vehicle theft rates.
[0005] However, under severe impact or vibration, the locking element may still unexpectedly retract in the unlocking direction, leading to unintended unlocking. To address this, the relevant technology adds a safety block to the locking module: in the locked state, the safety block abuts against the locking element, restricting its retraction; during unlocking, the drive mechanism moves the control element, which in turn rotates the switch element, causing the safety block to disengage from the locking element, releasing the restriction on the locking element, allowing it to retract to the unlocked position. During locking, the drive mechanism releases the force on the control element, and the locking element returns to the locked position under the action of a torsion spring, thus achieving locking. Simultaneously, the safety element returns to its original position under the action of another torsion spring, further restricting the retraction of the locking element.
[0006] Although the aforementioned safety block improves the ability to resist disturbances, the overall number of parts in the locking module is relatively large, resulting in high manufacturing costs and process difficulty. There is an urgent need to further simplify the locking module.
[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may contain information that does not constitute prior art. Utility Model Content
[0008] The purpose of this disclosure is to overcome at least one of the above-mentioned technical defects and to provide a locking actuator, a locking module, and a vehicle lock. The control component drives the safety component to move along a first direction or a second direction, so that the safety component drives the locking component to lock or unlock. That is, locking and unlocking are achieved by omitting the switch component and the torsion spring, reducing the number of parts in the locking actuator, simplifying the locking module, and reducing the manufacturing cost and process difficulty of the locking module.
[0009] The purpose of this disclosure is achieved through the following technical solution:
[0010] In a first aspect, this disclosure provides a locking actuator, which has a locked position and an unlocked position, and includes a locking member and a safety member. When the locking member is in the locked position, the safety member blocks the unlocking path of the locking member. The mechanism is characterized in that...
[0011] The safety element can move along a first direction to move the locking element to the locked position, and can also move along a second direction opposite to the first direction to move the locking element to the unlocked position;
[0012] The locking mechanism further includes a control component, which is fixedly connected to the safety component and can drive the safety component to move along the first direction and the second direction.
[0013] In some implementations, one of the locking member and the safety member has a mating protrusion and the other has a mating groove. The mating protrusion abuts against the inner wall of the mating groove, so that the safety member can move in a first direction to move the locking member to the locked position, and can move in a second direction to move the locking member to the unlocked position.
[0014] In some implementations, the locking element is rotatably configured, the safety element is rotatably configured, and both the first direction and the second direction are rotational directions.
[0015] In some implementations, the mating groove is located at one end of the locking member; the rotation axis of the safety member is located between the two ends of the safety member; the mating protrusion is located at the first end of the safety member; and the control member is fixedly connected to the second end of the safety member.
[0016] In some implementations, the second end of the safety component has a protruding sleeve portion, and the control component is sleeved on the sleeve portion;
[0017] The locking actuator further includes a connector, the sleeve portion is provided with a connector hole, the first end of the connector is inserted into the connector hole, and the second end of the connector is provided with a limiting portion, the limiting portion abutting against the control member to restrict the control member on the sleeve portion.
[0018] In some implementations, the control element is a spring.
[0019] Secondly, this disclosure provides a locking module, including a drive mechanism and a locking actuator as described in any of the above implementations, wherein the drive mechanism is configured to drive the control element.
[0020] In some implementations, the drive mechanism includes a power output shaft and a crank, one end of which is connected to the power output shaft and the other end of which is connected to the control element.
[0021] In some implementations, the drive mechanism further includes a torsion spring, which is sleeved on the power output shaft. The two ends of the torsion spring abut against the power output shaft and the crank, respectively. The power output shaft is connected to the crank via the torsion spring.
[0022] Thirdly, this disclosure provides a vehicle lock, including a gate and the aforementioned locking module, wherein the locking member engages with the gate when in the locked position.
[0023] Compared with the prior art, this disclosure has at least the following advantages:
[0024] In the aforementioned locking actuator, the control component and the safety component are fixedly connected. Under the action of the drive mechanism, the control component moves the safety component, allowing it to move along a first direction and a second direction. When the safety component moves along the first direction, it moves the locking component to the locked position, thus achieving the locking operation. When the safety component moves along the second direction, it moves the locking component to the unlocked position, thus achieving the unlocking operation. In other words, by using the control component to drive the safety component, both locking and unlocking operations are achieved. This eliminates the need for the switching component and torsion spring in the locking actuator, simplifying its structure and reducing the manufacturing cost and process complexity of the locking module.

Detailed Implementation
[0031] To facilitate understanding of this disclosure, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this disclosure are shown in the drawings. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide the reader with a more thorough and complete understanding.
[0032] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0034] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0035] like Figures 1 to 3 As shown, the locking actuator 10a of this disclosure has a locked position 101 and an unlocked position 102, and includes a locking member 100 and a safety member 200. The locking member 100 can move between the locked position 101 and the unlocked position 102, that is, the locking member 100 can be switched to the locked position 101 and fixedly connected to the external gate disc 20 to realize the locking operation of the rotating gate disc 20. The locking member 100 can be switched to the unlocked position 102 and separated from the external gate disc 20, so that the gate disc 20 can rotate freely.
[0036] When the locking member 100 is in the locked position 101, the safety member 200 blocks the unlocking path of the locking member 100. That is, the safety member 200 is located in the unlocking path of the locking member 100 and abuts against the locking member 100. In other words, the safety member 200 abuts against the side of the locking member 100 away from the gate 20, so that the safety member 200 prevents the locking member 100 from moving toward the unlocked position 102, thus preventing the locking member 100 from unlocking under the action of external force. The safety member 200 can move in two opposite directions. Specifically, the safety member 200 can move in the first direction A to move the locking member 100 to the locked position 101, and can move in the second direction B to move the locking member 100 to the unlocked position 102. The first direction A and the second direction B are opposite.
[0037] The locking actuator 10a also includes a control element 300, which is configured to connect to the power output end of the drive mechanism 10b and is fixedly connected to the safety element 200. Driven by the drive mechanism 10b, the control element 300 can move the safety element 200 along a first direction A and a second direction B, causing the safety element 200 to switch the locking element 100 between a locked position 101 and an unlocked position 102.
[0038] like Figure 2 and Figure 3 As shown, in this embodiment, when the locking member 100 is in the locked position 101, the locking member 100 is fixedly connected to the external gate disc 20, and the safety member 200 abuts against the side of the locking member 100 away from the gate disc. When unlocking, the drive mechanism 10b drives the control member 300 to move, the control member 300 drives the safety member 200 to move along the second direction B, and the safety member 200 drives the locking member 100 to move along the unlocking direction until the locking member 100 enters the unlocked position 102. When locking, the drive mechanism 10b drives the control member 300 to move in another direction, the control member 300 drives the safety member 200 to move along the first direction A, and the safety member 200 drives the locking member 100 to move along the locking direction until the locking member 100 enters the locked position 101. When the locking member 100 enters the locked position 101, the safety member 200 abuts against the side of the locking member 100 away from the gate disc 20.
[0039] It is understood that the locking actuator 10a also includes a housing 700, and the locking element 100, the safety element 200 and the control element 300 are all movably disposed within the housing 700.
[0040] The aforementioned locking actuator 10a has a control component 300 fixedly connected to a safety component 200. Under the action of the drive mechanism 10b, the control component 300 drives the safety component 200, allowing it to move along a first direction A and a second direction B. When the safety component 200 moves along the first direction A, it moves the locking component 100 to the locked position 101, thus achieving the locking operation. When the safety component 200 moves along the second direction B, it moves the locking component 100 to the unlocked position 102, thus achieving the unlocking operation. In other words, by using the control component 300 to drive the safety component 200, both locking and unlocking operations are achieved. This eliminates the need for the switching component and torsion spring in the locking actuator 10a, simplifying its structure and reducing the manufacturing cost and process complexity of the locking module 10.
[0041] like Figure 2 As shown, in some embodiments, one of the locking member 100 and the safety member 200 is provided with a mating protrusion 210, and the other is provided with a mating groove 103. The mating protrusion 210 is located in the mating groove 103 and abuts against the inner wall of the mating groove 103, so that the safety member 200 can move along the first direction A to drive the locking member 100 to the locked position 101, and can move along the second direction B to drive the locking member 100 to the unlocked position 102.
[0042] In this embodiment, when the safety member 200 moves along the first direction A, the mating protrusion 210 abuts against the inner wall of the mating groove 103 to push the locking member 100 from the unlocked position 102 to the locked position 101, thereby causing the locking member 100 to enter the locked position 101. When the locking member 100 enters the locked position 101, the mating protrusion 210 abuts against the inner wall of the mating groove 103 to prevent the locking member 100 from moving towards the unlocked position 102, thus avoiding the problem of the locking member 100 being unlocked by external force. When the safety member 200 moves along the second direction B, the mating protrusion 210 abuts against the inner wall of the mating groove 103 to push the locking member 100 from the locked position 101 to the unlocked position 102, thereby causing the locking member 100 to enter the unlocked position 102.
[0043] like Figure 2 As shown, the locking member 100 is rotatably configured, and the safety member 200 is rotatably configured, with the first direction A and the second direction B both being rotational directions.
[0044] like Figure 2As shown, in some embodiments, a mating groove 103 is provided at one end of the locking member 100. The rotation axis of the safety member 200 is located between the two ends of the safety member 200, that is, the portion between the two ends of the safety member 200 is rotatably connected to the housing 700. A mating protrusion 210 is provided at the first end of the safety member 200, and a control member 300 is fixedly connected to the second end of the safety member 200. In this embodiment, when the safety member 200 rotates along the first direction A, the mating protrusion 210 pushes the inner wall of the mating groove 103 along the first direction A, causing the locking member 100 to move toward the upper locking position 101. When the safety member 200 rotates along the second direction B, the mating protrusion 210 pushes the inner wall of the mating groove 103 along the second direction B, causing the locking member 100 to move toward the unlocking position 102.
[0045] like Figure 4 As shown, in some embodiments, the second end of the safety element 200 has a protruding sleeve portion 220, and the control element 300 is sleeved on the sleeve portion 220, so that the control element 300 is pre-fixed on the safety element 200. The locking actuator 10a also includes a plug 400, the sleeve portion 220 has a plug hole 221, the first end of the plug 400 is inserted into the plug hole 221, and the second end of the plug 400 has a limiting portion 410, which abuts against the control element 300 to restrict the control element 300 on the sleeve portion 220, thereby fixing the control element 300 on the safety element 200.
[0046] like Figure 3 As shown, in some embodiments, the control element 300 is a spring. It is understood that when the safety element 200 rotates to its limit position, due to control precision issues, the drive mechanism 10b may continue to drive for a certain period. However, due to the restriction of the safety element 200, the drive mechanism 10b cannot continue to rotate, causing it to stall and overheat, which can easily damage it. Therefore, in this embodiment, the control element 300 is a spring. When the safety element 200 rotates to its limit position, because the spring is elastic, the safety element 200 does not completely restrict the rotation of the drive mechanism 10b; that is, the transmission chain between the safety element 200 and the drive mechanism 10b is not completely locked. At this time, the drive mechanism 10b can still rotate slightly, reducing the risk of stalling and extending its service life.
[0047] like Figure 3 As shown, this disclosure also provides a locking module 10, including a drive mechanism 10b and a locking execution mechanism 10a of any of the above embodiments. The drive mechanism 10b is configured to drive a control member 300 so that the control member 300 drives the safety member 200 to move along a first direction A and a second direction B.
[0048] like Figure 3As shown, in some embodiments, the drive mechanism 10b includes a power output shaft 500 and a crank 600. One end of the crank 600 is connected to the power output shaft 500, and the other end of the crank 600 is connected to the control member 300. In this embodiment, the output shaft 500 drives the crank 600 to rotate, and the crank 600 drives the control member 300 to move, causing the control member 300 to drive the safety member 200 to move along the first direction A and the second direction B.
[0049] like Figure 3 As shown, in some embodiments, the drive mechanism 10b further includes a torsion spring (not shown), which is sleeved on the power output shaft 500. The two ends of the torsion spring abut against the power output shaft 500 and the crank 600, respectively. The power output shaft 500 is connected to the crank 600 via the torsion spring. In this embodiment, when the safety element 200 rotates to its limit position, due to the elasticity of the torsion spring, the transmission chain between the safety element 200 and the power output shaft 500 is not completely locked. At this time, the drive mechanism 10b can still rotate slightly, reducing the risk of the drive mechanism 10b stalling and extending its service life.
[0050] like Figure 1 As shown, this disclosure also provides a vehicle lock, characterized in that it includes a gate 20 and a locking module 10 of any of the above embodiments, wherein the locking member 100 is engaged with the gate 20 when in the locked position 101.
[0051] Compared with the prior art, this disclosure has at least the following advantages:
[0052] The control component 300 is fixedly connected to the safety component 200. Under the action of the drive mechanism 10b, the control component 300 drives the safety component 200, allowing the safety component 200 to move along the first direction A and the second direction B. When the safety component 200 moves along the first direction A, it drives the locking component 100 to the locked position 101 to achieve the locking operation. When the safety component 200 moves along the second direction B, it drives the locking component 100 to the unlocked position 102 to achieve the unlocking operation. That is, by driving the safety component 200 through the control component 300, the locking and unlocking operations are realized, eliminating the switching component and torsion spring of the locking actuator 10a, simplifying the structure of the locking actuator 10a, and reducing the manufacturing cost and process complexity of the locking module 10.
[0053] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
