Description

Technical Field

[0001] This invention relates to the field of motorcycle technology, and in particular to a manual / automatic unlocking device. Background Technology

[0002] Existing motorcycle seat locks on the market offer both electric and manual unlocking methods, with some integrating both. However, existing manual / automatic seat locks typically use two unlocking cables, such as... Figure 1 As shown, the common arrangement on the market uses a first cable 10′ and a second cable 20′. One end of the first cable 10′ and the second cable 20′ are connected to the pawl 120 on the lock body 100. One end of the first cable 10′ is connected to the manual lock cylinder, and one end of the second cable 20′ is connected to the unlocking motor. The pawl 120 can be pulled by either the manual lock cylinder or the unlocking motor, causing the lock hook 110 to spring up. At this time, the lock body 100 is in the unlocked state. When the manual lock cylinder or the unlocking motor is reset, the lock body needs to be locked by pressing the lock hook 110 with the buckle of the object being locked.

[0003] Because the existing manual / automatic transmission method uses two unlocking cables, the overall structure is more complex and the cost is higher. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to solve the problems of complex structural layout and high cost in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a manual / automatic unlocking device, comprising a pawl acting on the lock body, and including:

[0006] An unlocking mechanism includes a mounting bracket having a proximal end and a distal end. A lock cylinder is located at the proximal end of the mounting bracket. A lock cylinder head is coaxially located at one end of the lock cylinder. The lock cylinder head has a first groove extending from the proximal end to the distal end. A transmission shaft is movably mounted on the first groove. A first support arm is rotatably mounted on the transmission shaft. An unlocking motor is located at the distal end of the mounting bracket. A motor support arm is located at the output end of the unlocking motor. A second support arm is located on the motor support arm. The second support arm has a second groove, and the transmission shaft movably passes through the second groove.

[0007] The cable has one end connected to the first support arm and the other end connected to the pawl of the lock body.

[0008] More preferably, the lock cylinder head includes:

[0009] A rotating part, which is coaxially connected to the lock cylinder; and

[0010] An extension portion is perpendicularly connected to the rotating portion, the extension portion extends from the proximal end to the distal end, and the first groove is formed in the extension portion.

[0011] More preferably, one end of the first support arm is provided with a clamping slot, and the other end is provided with a waist-shaped compensation hole. The transmission shaft passes through the compensation hole. Both ends of the cable have cable heads, one end of which is connected to the pawl of the lock body, and the other end of which is connected to the clamping slot.

[0012] More preferably, the second arm includes:

[0013] The connecting part has a motor bayonet, and one end of the motor support arm is connected to the motor bayonet; and

[0014] An arc-shaped portion is provided at one end of the connecting portion away from the motor support arm, and the arc-shaped portion has an arc-shaped second sliding groove.

[0015] More preferably, the rotation trajectory of the transmission shaft driven by the lock cylinder head matches the second slide groove.

[0016] More preferably, during manual unlocking, the lock cylinder head drives the transmission shaft to move along the second slide groove; during electric unlocking, the second support arm drives the transmission shaft to move along the first slide groove.

[0017] More preferably, it also includes a gasket, which is connected to the transmission shaft to achieve axial positioning of the lock cylinder head, the first arm, and the second arm.

[0018] More preferably, the unlocking motor and the mounting bracket are detachably connected by fasteners.

[0019] More preferably, it also includes a crossbeam for mounting on the vehicle body, the lock body being located at the near end of the crossbeam, the crossbeam having a mounting plate, and the mounting bracket being detachably connected to the mounting plate.

[0020] More preferably, the mounting bracket has a mounting slot at its proximal end, which is used to fix the cable.

[0021] Compared with the prior art, the manual / automatic unlocking device provided by this invention has the following advantages:

[0022] This invention integrates the lock cylinder and unlocking motor into one unit, allowing two unlocking methods to be achieved by a single cable pulling the pawl to rotate, thereby causing the lock hook to spring up and unlock the lock body. Specifically, for manual unlocking, the manual unlocking key is inserted into the lock cylinder, and the lock cylinder head is turned, causing the transmission shaft to move along the second slide groove of the second arm. The transmission shaft drives the first arm to move from the proximal end to the distal end, and the first arm pulls the pawl via the cable to achieve the unlocking purpose. For electric unlocking, the unlocking motor is activated, and the motor arm pulls the second arm and the transmission shaft to move from the proximal end to the distal end in the first slide groove of the lock cylinder head. The transmission shaft drives the first arm to move from the proximal end to the distal end, and the first arm pulls the pawl via the cable to achieve the unlocking purpose. This invention solves the problems of complex arrangement and high cost caused by two cables in the prior art, and achieves decoupling of electric and manual unlocking. Attached Figure Description

[0037] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0038] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" used to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0039] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0043] It should be noted that in existing lock bodies, such as Figure 1 As shown, the lock body 100 includes a lock hook 110 and a pawl 120. The pawl 120 and the lock hook 110 are linked together. When unlocking, the pawl 120 is usually turned by an external force to drive the lock hook 110 to rotate and unlock. When the external force applied to the pawl 120 is removed, the lock hook 110 can be rotated back to the locked state under the pressure of the buckle of the locked object.

[0044] like Figures 2-7 As shown, this embodiment provides a manual / automatic unlocking device, including an unlocking mechanism 400 and a pull cable 500. The pull cable 500 acts on the pawl 120 of the lock body 100. The purpose of the unlocking mechanism 400 is to enable both electric and manual unlocking of the pawl 120 through a single pull cable 500, thereby decoupling electric and manual operation and solving the problems of complex arrangement and high cost caused by two pull cables in the prior art.

[0045] In a specific embodiment, the unlocking mechanism 400 includes a mounting bracket 401 having a proximal end and a distal end. A lock cylinder 404 is located at the proximal end of the mounting bracket 401. A lock cylinder head 405 is coaxially located at one end of the lock cylinder 404. The lock cylinder head 405 has a first groove 4053 extending from the proximal end to the distal end. A transmission shaft 406 is movably mounted on the first groove 4053. A first support arm 407 is rotatably mounted on the transmission shaft 406. An unlocking motor 408 is located at the distal end of the mounting bracket 401. A motor support arm 410 is located at the output end of the unlocking motor 408. A second support arm 411 is located on the motor support arm 410. A second groove 4114 is located on the second support arm 4114. The transmission shaft 406 movably passes through the second groove 4114. One end of the pull cable 500 is connected to the first support arm 407, and the other end... One end is connected to the pawl 120 of the lock body 100; thus, when manually unlocking, the manual unlocking key 600 is inserted into the lock cylinder 404, and the lock cylinder head 405 is turned to drive the transmission shaft 406 to move along the second slide groove 4114 of the second support arm 411. The transmission shaft 406 drives the first support arm 407 to move from the near end to the far end. The first support arm 407 pulls the pawl 120 through the cable 500 to achieve the unlocking purpose; when electrically unlocking, the unlocking motor 408 is started, and the motor support arm 410 pulls the second support arm 411 and the transmission shaft 406 to move from the near end to the far end in the first slide groove 4053 of the lock cylinder head 405. The transmission shaft 406 drives the first support arm 407 to move from the near end to the far end. The first support arm 407 pulls the pawl 120 through the cable 500 to achieve the unlocking purpose.

[0046] In the above embodiment, the lock cylinder 404 and the unlocking motor 408 are integrated into one unit, so that the two unlocking methods can be achieved by pulling the pawl 120 to rotate through a single cable 500, thereby causing the lock hook 110 to spring up and unlock the lock body 100. This solves the problems of complex arrangement and high cost caused by two cables in the prior art, and achieves decoupling between electric and manual operation.

[0047] In the above embodiment, when manually unlocking, the lock cylinder head 405 drives the transmission shaft 406 to move along the second slide groove 4114; when electrically unlocking, the second support arm 411 drives the transmission shaft 406 to move along the first slide groove 4053.

[0048] It should be noted that the "proximal end" refers to the end closer to the lock body 100, and the "distal end" refers to the end farther away from the lock body 100.

[0049] In some embodiments, the lock cylinder head 405 includes a rotating portion 4051 and an extension portion 4052, wherein the rotating portion 4051 is coaxially connected to the lock cylinder 404; the extension portion 4052 is perpendicularly connected to the rotating portion 4051, and the extension portion 4052 extends from a proximal end to a distal end, and a first groove 4053 is formed in the extension portion 4052; thus, after the manual unlocking key 600 is inserted into the lock cylinder 404 and the rotating portion 4051 is rotated, the extension portion 4052 is located at the rotating portion 4051. Driven by 1, it makes a circular motion, which in turn drives the transmission shaft 406 to move along the second slide groove 4114 of the second arm 411. The transmission shaft 406 drives the first arm 407 to move from the proximal end to the distal end. The first arm 407 pulls the pawl 120 through the cable 500 to achieve the unlocking purpose. In addition, the extension part 4052 extends from the proximal end to the distal end to meet the movement requirements of the transmission shaft 406 during electric unlocking and can avoid the second arm 411 and the lock cylinder head 405 from interfering with each other.

[0050] In some embodiments, one end of the first arm 407 is provided with a clamp slot 4071, and the other end is provided with a waist-shaped compensation hole 4072. The transmission shaft 406 is provided through the compensation hole 4072. The two ends of the cable 500 are provided with cable heads 501, one end of which is connected to the pawl 120 of the lock body 100, and the other end of which is connected to the clamp slot 4071. Preferably, the cable head 501 and the clamp slot 4071 are detachably connected to facilitate the assembly of the manual and automatic unlocking device. The compensation hole 4072 can meet the requirement that the transmission shaft 406 drives the first arm 407 from the proximal end to the distal end under the drive of the lock cylinder head 405 or the second arm 411 to unlock the lock body 100.

[0051] In some embodiments, the second support arm 411 includes a connecting portion 4111 and an arc-shaped portion 4113. The connecting portion 4111 has a motor bayonet 4112, and one end of the motor support arm 410 is connected to the motor bayonet 4112. The arc-shaped portion 4113 is located at the end of the connecting portion 4111 away from the motor support arm 410, and the arc-shaped portion 4113 has an arc-shaped second slide groove 4114. By setting the motor bayonet 4112 and the second slide groove 4114, the motor support arm 410 and the transmission shaft 406 can be connected, thereby driving the first support arm 407 to move. The second slide groove 4114 is designed with an arc-shaped structure, which can meet the trajectory movement of the transmission shaft 406 during manual unlocking, avoiding motion interference that affects the unlocking function.

[0052] In the above embodiment, during the manual unlocking process, in order to avoid interference with the second arm 411 when the lock cylinder head 405 drives the transmission shaft 406 to rotate around the rotating part 4051, the rotation trajectory of the transmission shaft 406 driven by the lock cylinder head 405 matches the second slide groove 4114. Thus, the transmission shaft 406 will not interfere with the trajectory of the second arm 411 when rotating around the rotating part 4051, thereby achieving unlocking.

[0053] In some embodiments, to facilitate the connection of the lock cylinder head 405, the first arm 407, and the second arm 411 via the transmission shaft 406, the manual / automatic unlocking device further includes a washer 412. One end of the transmission shaft 406 passes sequentially through the first groove 4053 of the lock cylinder head 405, the compensation hole 4072 on the first arm 407, and the second groove 4114 on the second arm 411, and then connects to the washer 412 to achieve axial limiting of the lock cylinder head 405, the first arm 407, and the second arm 411. The lock cylinder head 405, the first arm 407, and the second arm 411 can rotate around the transmission shaft 406 to avoid interference during manual and electric unlocking.

[0054] In some embodiments, the unlocking motor 408 and the mounting bracket 401 are detachably connected by a fastener 409 to facilitate the installation, replacement and maintenance of the unlocking motor 408, making the operation convenient and flexible; preferably, the fastener 409 is a fastening bolt; more preferably, it is an internal hexagonal fastening bolt.

[0055] In some embodiments, a crossbeam 200 is also included, which is used for mounting on a vehicle body (such as a motorcycle). The lock body 100 is located near the end of the crossbeam 200. A mounting plate 300 is provided on the crossbeam 200. The mounting bracket 401 is detachably connected to the mounting plate 300 to facilitate the disassembly, replacement, and maintenance of this manual / automatic unlocking device. In some examples, mounting holes 403 can be provided on the mounting bracket 401 for fixing the mounting bracket 401 to the mounting plate 300 by fasteners (not shown), thereby achieving a detachable connection between the device and the mounting plate 300.

[0056] In some embodiments, the mounting bracket 401 has a mounting slot 402 at its proximal end, which is used to fix the cable 500 so that the pawl 120 can be pulled by the cable head 501 to unlock.

[0057] The working process of this invention is as follows:

[0058] When unlocking manually, insert the manual unlocking key 600 into the lock cylinder 404 and turn the lock cylinder head 405 to drive the transmission shaft 406 to move along the second slide groove 4114 of the second arm 411. The transmission shaft 406 drives the first arm 407 to move from the near end to the far end. The first arm 407 pulls the pawl 120 through the cable 500 to achieve the unlocking purpose.

[0059] When unlocking is performed electrically, the unlocking motor 408 is activated. The motor arm 410 pulls the second arm 411 and the transmission shaft 406 to move from the near end to the far end in the first slide groove 4053 of the lock cylinder head 405. The transmission shaft 406 drives the first arm 407 to move from the near end to the far end. The first arm 407 pulls the pawl 120 through the cable 500 to achieve the unlocking purpose.

[0060] In summary, the manual / automatic unlocking device provided by this embodiment of the invention integrates the lock cylinder 404 and the unlocking motor 408 into one unit, enabling two unlocking methods to be achieved by pulling the pawl 120 through a single cable 500, thereby causing the lock hook 110 to spring up and unlock the lock body 100. This solves the problems of complex arrangement and high cost caused by two cables in the prior art, and achieves decoupling of electric and manual operation.
