Description

Technical Field

[0001] This invention relates to the field of bicycle lock technology, and more particularly to a bicycle equipped with a frame-integrated steel cable lock structure. Background Technology

[0002] As a traditional mode of transportation, bicycles offer advantages over modern transportation methods, including being environmentally friendly, convenient, and fast. With the continuous improvement of people's living standards, the pursuit of a healthy lifestyle is accelerating, and cycling, as an environmentally friendly and fitness-oriented activity, is becoming increasingly popular. However, with the rise of the bicycle industry, more and more high-end bicycles are gradually entering the public eye. Therefore, ensuring bicycle theft prevention is a pressing issue that needs to be addressed.

[0003] Steel cable locks are a common method of bicycle theft prevention. They are used to secure bicycles to fixed objects along the roadside, such as trees, lampposts, or utility poles. This method is very effective in preventing bicycle theft.

[0004] However, in practical use, existing steel cable locks have been found to have the following shortcomings:

[0005] (1) The lock body of the steel cable lock is exposed, while the clamping and locking parts inside the steel cable lock are made of stainless steel or other metal materials. During the process of the clamping and locking parts engaging, when rainwater enters between the clamping and locking parts, it is easy to cause rust between the clamping and locking parts and make it impossible to open.

[0006] (2) The fixed objects that can be tied to a bicycle are limited by the length of the steel cable lock and the distance between the bicycle and the fixed object. In the existing steel cable lock, the bicycle needs to be close to the fixed object to be tied together, which greatly affects the flexibility of the bicycle. Summary of the Invention

[0007] This invention discloses a bicycle with a frame-integrated steel cable lock structure to solve the problems in the prior art where the lock body of the steel cable lock is exposed to the outside, and when rainwater enters between the clamping and locking parts, it is easy to cause rust between the clamping and locking parts, making it impossible to open. Also, if you want to tie the bicycle to a roadside fixed object, you need to put the bicycle tightly against the roadside fixed object, which greatly affects the bicycle's flexibility.

[0008] To solve the above-mentioned technical problems, the following technical solution is proposed:

[0009] A bicycle with an in-frame steel cable lock structure, including a frame, a lock body and a bolt. The lock body is placed inside the hollow part of the frame and fixedly connected to the frame. There is a second through hole on the frame, and the bolt passes through the first through hole and is clamped with the lock body.

[0010] Among them, the lock body includes:

[0011] A housing fixedly connected to the frame. The side wall of the housing has a first through hole adapted to the second through hole, and a chute is provided inside the housing.

[0012] A buckle member slidably arranged in the chute. There is also a first spring member between the buckle member and the housing, and the first spring member abuts against the buckle member to move along the chute.

[0013] A pushing device arranged inside the housing. The output end of the pushing device contacts the side of the buckle member away from the first spring.

[0014] An induction element arranged inside the housing, and the induction element forms a locking induction area.

[0015] A rotary rod rotatably arranged inside the housing. One end of the rotary rod extends towards the first through hole, and the other end extends towards the induction area.

[0016] A control device electrically connected to the pushing device and the induction element, and the control device is also wirelessly or wiredly connected to an external control end and is used to control the pushing device.

[0017] The bolt sequentially passes through the second through hole and the first through hole. The buckle member is engaged with the annular groove, and the bolt pushes the end of the rotary member away from the first through hole towards the induction area.

[0018] Preferably, a card hole is provided on the upper end surface of the buckle member. The axis of the card hole is parallel to the axis of the first through hole, and the center of the first through hole is located on the movement track of the center of the card hole.

[0019] Preferably, a stop block is further provided on the side of the chute away from the first spring member, and stop blocks are provided on both sides of the chute. The buckle member has a "convex" shape structure, and the protruding part of the buckle member passes through between the two stop blocks.

[0020] Preferably, the pushing device includes a rotating motor and a rotating block. The lower end surface of the rotating block is connected to the rotating motor, and the upper end surface of the rotating block has a spiral structure, and the buckle member always abuts against the upper end surface of the rotating block.

[0021] Preferably, a limiting block is provided at the highest point of the upper surface of the rotating block, and the bottom end of the limiting block extends toward the lowest point of the upper surface of the rotating block. When the fastener moves to the lowest or highest point of the upper surface of the rotating block, the side wall of the fastener abuts against the limiting block.

[0022] Preferably, the device also includes a second spring member, one side of which abuts against the inner wall of the housing, and the other side abuts against the end of the rotary rod near the first through hole. When the pin is not inserted into the first through hole, the end of the rotary rod near the first through hole of the second spring member abuts against the first through hole and partially overlaps with the first through hole.

[0023] Preferably, the pin includes a steel cable portion, a main body portion, and a top portion arranged sequentially. The annular groove is disposed on the side wall of the main body portion. The top portion has a frustum-shaped structure. When the latching member abuts against the stop block, the distance from the edge position of the latching member near the first spring member to the center of the first through hole is greater than the radius of the small circular end of the top portion.

[0024] Preferably, when the buckle is engaged with the annular groove, the top is in contact with the bottom of the first through hole.

[0025] Preferably, the bottom of the first through hole is provided with a hemispherical protrusion, and the top is in contact with the protrusion.

[0026] Preferably, the end of the steel cable portion away from the main body portion is also provided with a ring, through which the top, the main body portion, and the steel cable portion can all pass.

[0027] Beneficial effects:

[0028] (1) In this invention, the lock body is set in the hollow part of the frame, which not only greatly increases the security of the lock body, but also effectively prevents wind and rain from corroding the lock body.

[0029] (2) In this invention, the pin is connected to the lock body at only one end, while the other end is provided with a ring. When in use, the top, the main body and the steel cable pass through the ring to form a loop, which can tie the bicycle to the fence on the side of the road, greatly increasing the freedom of locking the bicycle.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] The following detailed description of embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0046] This invention relates to a bicycle with a frame-integrated cable lock structure. Please refer to [link / reference]. Figure 1-12 It includes a frame 9, a lock body 1 and a pin 2. The lock body 1 is placed in the hollow part of the frame 9 and is fixedly connected to the frame 9. The frame 9 is provided with a second through hole, and the pin 2 passes through the first through hole 33 and engages with the lock body 1.

[0047] The lock body 1 includes a housing 3, a latching member 4, a pushing device 5, a sensing element 6, a rotary rod 7, and a control device 8. The housing 3 is placed in the hollow part of the frame 9 and is fixedly connected to the inner side of the frame 9. The side wall of the housing 3 is provided with a first through hole 33 that matches the second through hole. The housing 3 is also provided with a sliding groove 31. The latching member 4 is slidably disposed in the sliding groove 31. A first spring member 32 is provided between the latching member 4 and the housing 3. The first spring member 32 abuts against the latching member 4 and moves along the sliding groove 31. The pushing device 5 is disposed in the housing 3, and the output end of the pushing device 5 contacts the side of the latching member 4 away from the first spring. The sensing element 6 is disposed in the housing 3 and forms a locking sensing area. The rotary rod 7 is rotatably disposed in the housing 3. One end of the rotary rod 7 extends toward the first through hole 33, and the other end extends toward the sensing area. The control device 8 is electrically connected to the pushing device 5 and the sensing element 6, and the control device 8 is also wirelessly or wiredly connected to an external control terminal.

[0048] During use, the pin 2 passes through the second through hole and the first through hole 33 in sequence. Under the action of the first spring 32, the latch 4 moves away from the first spring 32. At this time, the latch 4 engages with the annular groove 21, thus allowing the pin 2 to be latched inside the lock body 1. Simultaneously, as the pin 2 is inserted into the lock body 1, it pushes the end of the rotary member near the first through hole 33 away from the first through hole, while the other end of the rotary member moves towards the sensing area. At this time, the sensing element 6 in the sensing area detects the rotary member and transmits a sensing signal to... The control device 8 converts the sensing signal into locking information and transmits it to an external control terminal, allowing the user to confirm the bicycle's locking status. When the user needs to unlock the bicycle, they only need to send an unlocking command to the control device 8 through the external control terminal. After receiving the unlocking command, the control device 8 controls the push device 5 to start. The push device 5 pushes the buckle 4 towards the first spring 32. At this time, the buckle 4 disengages from the annular groove 21 on the pin 2, thereby completing the unlocking work of the pin 2 and allowing the pin 2 to be pulled out of the lock body 1.

[0049] In this embodiment, a card hole 41 is provided on the upper end surface of the buckle member 4. The axis of the card hole 41 is parallel to the axis of the first through hole, and the center of the first through hole is located on the movement track of the center of the card hole 41. When the bolt 2 is inserted into the lock body 1, the bolt 2 sequentially passes through the first through hole 33 and the buckle. And when the card hole 41 is aligned with the annular groove 21, under the action of the first spring member 32, the buckle member 4 sinks into the annular groove 21, so that the buckle member 4 is engaged with the bolt 2. At the same time, since the center of the first through hole is located on the movement track of the center of the card hole 41, when the buckle member 4 is engaged with the bolt 2, the area of the buckle member 4 sinking into the annular groove 21 is the largest, which makes the engagement between the buckle member 4 and the bolt 2 more firm.

[0050] In this embodiment, a stop block 35 is further provided on the side of the chute 31 away from the first spring member 32, and stop blocks 35 are provided on both side walls of the chute 31. The buckle member 4 has a "convex" shape structure, and the protruding part of the buckle member 4 passes through between the two stop blocks 35. When the bolt 2 is in the state of not being inserted into the lock body 1, the buckle member 4 abuts against the stop block 35, and the stop block 35 is used to prevent the buckle member 4 from脱离滑槽31.

[0051] In this embodiment, the bolt 2 includes a steel cable part 22, a main body part 23 and a top part 24 arranged in sequence. The annular groove 21 is arranged on the side wall of the main body part 23. When the buckle member 4 is engaged with the annular groove 21, the top part 24 contacts the bottom of the first through hole, so that when the bolt 2 is inserted into the through hole, the buckle member 4 can sink into the annular groove 21 more accurately, preventing the phenomenon that the buckle member 4 is aligned with the annular groove 21 when the bolt 2 is inserted into the through hole. More preferably, a hemispherical convex point 36 is provided at the bottom of the through hole, and the top part 24 contacts the convex point 36, reducing the contact area between the top part 24 and the bottom of the first through hole (that is, reducing the wear between the bolt 2 and the bottom of the first through hole). At the same time, after the bolt 2 is inserted into the first through hole, the bolt 2 can rotate more smoothly.

[0052] In the embodiment, the side wall of the top part 24 of the bolt 2 shrinks towards the axis of the main body part 23, so that the top part 24 forms a frustum-shaped structure. In order to enable the bolt 2 to pass through the buckle, when the buckle member 4 abuts against the stop block 35 (that is, the bolt 2 is in the state of not being inserted into the lock body 1), the distance from the edge position of the buckle near the first spring member 32 to the axis of the first through hole should be greater than the radius of the small end of the top part 24, so that when the bolt 2 is inserted into the first through hole, the small end of the top part 24 can pass through the overlapping part of the card hole 41 and the first through hole.

[0053] In this embodiment, the pushing device 5 includes a rotating motor 51 and a rotating block 52. The lower end face of the rotating block 52 is connected to the rotating motor 51, and the upper end face of the rotating block 52 has a spiral structure. The latching member 4 is in contact with the upper end face of the rotating block 52. When an external control terminal sends an unlocking command to the control device 8, the control device 8 responds to the unlocking command and controls the rotating motor 51 to start. The rotating motor 51 drives the rotating block 52 to rotate, so that the contact position between the latching member 4 and the rotating block 52 moves from the bottom end to the top end. As the contact position between the latching member 4 and the rotating block 52 changes, the latching member 4 moves towards the direction of the first spring member 32, so that the latching member 4 disengages from the annular groove 21, thereby completing the unlocking of the pin 2.

[0054] In this embodiment, a limiting block 53 is also provided at the highest point of the upper end surface of the rotating block 52, and the bottom end of the limiting block 53 extends to the lowest point of the upper end surface of the rotating block 52. When the fastener 4 moves to the lowest or highest point of the upper end surface of the rotating block 52, the side wall of the fastener 4 abuts against the limiting block 53, thereby preventing the rotating block 52 from rotating excessively, so that the fastener 4 cannot disengage from the annular groove 21.

[0055] In this embodiment, a second spring member 37 is also included. One side of the second spring member 37 abuts against the inner wall of the housing 3, and the other side abuts against the end of the rotary rod 7 near the first through hole. When the pin 2 is not inserted into the first through hole, the end of the rotary member near the first through hole held by the second spring member 37 partially overlaps with the first through hole. When the pin 2 is disengaged from the first through hole, the rotary member moves out of the sensing area under the action of the second spring member 37. At this time, the sensing element 6 in the sensing area senses that the rotary member has moved out of the sensing area and sends a reset command to the control device 8. The control device 8 responds to the reset command and rotates the motor 51 in the reverse direction, thereby making the contact position between the buckle 4 and the rotating block 52 located at the lowest end of the rotating block 52.

[0056] In this embodiment, since only one end of the pin 2 is connected to the lock body 1, a ring 25 is provided at the end of the steel cable 22 away from the main body 23 in order to realize the locking function. The top 24, the main body 23 and the steel cable 22 can all pass through the ring 25. During use, the top 24, the main body 23 and the steel cable 22 pass through the ring 25 to form a loop, so that the bicycle can be tied to the fence on the roadside.

[0057] In this embodiment, the frame 9 is also equipped with an unlocking device 10, which is electrically connected to the control device 8. The unlocking device 10 sends an unlocking command to the control device 8, thereby unlocking the lock body 1. It should be noted that the unlocking device 10 can be an external control terminal, and its unlocking method includes, but is not limited to, key unlocking, fingerprint unlocking, or mobile phone command unlocking.

[0058] Advantages:

[0059] (1) In this invention, the lock body is set in the hollow part of the frame, which not only greatly increases the security of the lock body, but also effectively prevents wind and rain from corroding the lock body.

[0060] (2) In this invention, the pin is connected to the lock body at only one end, while the other end is provided with a ring. When in use, the top, the main body and the steel cable pass through the ring to form a loop, which can tie the bicycle to the fence on the side of the road, greatly increasing the freedom of locking the bicycle.

[0061] It should be noted that the bicycles mentioned in this invention include, but are not limited to, pedal bicycles and electric bicycles, and other types of bicycles are also within the scope of protection of this invention.

[0062] The above-disclosed embodiments are merely a few specific examples of the present invention, but the present invention is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
