Description

Technical Field

[0001] This utility model belongs to the field of lock technology, specifically relating to a helmet lock and a cycling vehicle. Background Technology

[0002] With increasing concerns about travel safety, riders of two-wheeled or three-wheeled vehicles are required to wear helmets. However, since carrying a helmet is inconvenient, most people simply place it in the basket of their vehicle after riding. To prevent helmet loss, helmet locks have emerged.

[0003] Common helmet locks in existing technology involve a lock body installed in the basket and a lock hole on the helmet shell. After the helmet is placed in the basket, a latch in the lock body extends and inserts into the lock hole to lock it in place. This method requires the helmet shell to have a corresponding lock hole, which not only affects the helmet's structural strength but also increases its cost. Another common helmet lock method involves inserting the buckle of the helmet into a lock hole fixed to the bike frame. A latch, positioned perpendicular to the lock hole, then passes through a hole in the buckle to lock it in place. However, this method suffers from low buckle strength, especially at the edge of the hole, making it prone to breakage. Therefore, it not only has weak locking strength but also easily damages the buckle, rendering the helmet unwearable.

[0004] In view of the above, all types of helmet locks in the existing technology have drawbacks in terms of locking reliability and affecting the performance of the helmet itself, and urgently need to be improved. Utility Model Content

[0005] This utility model provides a helmet lock and a cycling vehicle, aiming to avoid the negative impact of helmet lock application on the performance of the helmet itself and improve the reliability of helmet locking.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: Firstly, a helmet lock is provided, suitable for locking a helmet with a snap-on buckle, wherein a first locking tooth surface is formed on the snap of the snap-on buckle. The helmet lock includes:

[0007] The lock housing is used to fix it to the vehicle body and has a lock hole for inserting the buckle. The lock housing has an assembly cavity and a locking channel that is adapted to the buckle.

[0008] The locking component is rotatably assembled in the assembly cavity and located on the side of the locking channel. The side of the locking component near the locking channel forms a second locking tooth surface.

[0009] An elastic torque element is disposed on the locking element to be suitable for driving the locking element to swing, so that the second locking tooth surface is close to the locking channel, and when the buckle is inserted into the position, the second locking tooth surface presses against the first locking tooth surface to lock the buckle.

[0010] The unlocking component is located in the assembly cavity and connected to the locking component. It is used to drive the locking component to swing away from the lock track to overcome the elastic force of the elastic torsion member, so that the second locking tooth surface disengages from the first locking tooth surface to unlock the buckle.

[0011] In one possible implementation, the unlocking component includes:

[0012] The unlocking drive component contacts the end of the locking component furthest from its rotating assembly when unlocked; and

[0013] Gear linkage mechanism, including motor and gear transmission assembly;

[0014] The unlocking drive component is equipped with spur teeth or racks, which are connected to the final gear of the gear transmission assembly and are driven by the final gear.

[0015] The unlocking drive unit uses a gear linkage mechanism to drive the locking unit to swing, so that the second locking tooth surface moves closer to or away from the locking track.

[0016] In some embodiments, the locking member has a movable groove at one end away from its rotating assembly, and the unlocking drive member passes through the movable groove at its end facing the locking member and is provided with a baffle; wherein the baffle abuts against the side of the locking member facing the locking channel, and there is a movable gap between the unlocking drive member and the groove wall of the movable groove.

[0017] For example, the end of the unlocking drive component away from the locking component is provided with a locking trigger boss. When the unlocking drive component moves to the correct position, it triggers the locking trigger boss, and the motor stops rotating.

[0018] For example, the upper part of the locking component is a rotating assembly part, the middle part is provided with a second locking tooth surface, and the lower part extends an operating arm; wherein, the rotating assembly part is assembled with the lock housing through a rotating shaft, and an elastic torque member is mounted on the rotating shaft, and a movable groove is opened in the lower part of the operating arm.

[0019] In one possible implementation, a fixing plate is provided inside the lock housing, and a locking channel is formed between the fixing plate and the second locking tooth surface. The locking channel is aligned with the lock hole. The buckle passes through the lock hole and extends into the locking channel to form a locking state. In the locking state, the side of the buckle away from the locking member abuts against the fixing plate.

[0020] In some embodiments, the plate surface opposite to the second locking tooth surface of the fixing plate is an arc surface, which is used to guide the buckle to gradually approach the second locking tooth surface when it is inserted into the locking channel.

[0021] For example, a locking sensor is provided at the end of the lock track away from the lock hole; when the locking sensor senses the buckle, it generates a successful locking signal and transmits it to the vehicle's central control system, and the locking member approaches the buckle, and the second locking tooth surface presses against the first locking tooth surface to form a locking state.

[0022] In one possible implementation, an identification circuit is provided inside the lock housing, and an identification chip is provided inside the latch; wherein, the identification circuit is used to read the information of the identification chip when the latch triggers the locking sensor.

[0023] The advantages of this helmet lock are as follows: Compared with the prior art, the buckle of this helmet lock serves both as a buckle for the helmet and can be inserted into the lock hole to lock the helmet by engaging the first locking tooth surface with the second locking tooth surface on the locking member, without altering the structure of the helmet body. This avoids the impact on structural strength caused by adding holes to the helmet body. After the buckle is inserted into the lock hole, the locking member, under the elastic force of the elastic torque member, drives the second locking tooth surface to elastically press against the first locking tooth surface, thus forming a surface-to-surface locking state. When the helmet needs to be used, the buckle can be easily removed by simply swinging the locking member through the unlocking component to separate the second locking tooth surface from the first locking tooth surface. The operation is simple and convenient. Compared with the prior art method of locking by inserting the latch into the hole in the lock hole, the surface-to-surface locking method is more reliable and avoids the problem of reduced strength caused by the buckle being drilled. Both the helmet structure itself and the buckle structure ensure that the helmet's performance is not affected, and the helmet locking structure has high strength and reliability.

[0024] Secondly, embodiments of this application also provide a cycling vehicle, including the aforementioned helmet lock.

[0025] Compared with existing technologies, the vehicle provided in this application adopts the aforementioned helmet lock. After the buckle is inserted into the lock hole, the locking member, under the elastic force of the elastic torque member, drives the second locking tooth surface to elastically press against the first locking tooth surface, thereby forming a surface-to-surface locking state. Compared with the existing technology of locking by inserting the locking tongue into the hole in the lock hole, the surface-to-surface locking method is more reliable and can avoid the problem of buckle strength reduction due to opening. Both the helmet's structure itself and the helmet's buckle structure can ensure that the helmet's performance is not affected, and the helmet locking structure has high strength and reliability.

[0038] 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. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0039] Please refer to the following: Figures 1 to 8 The helmet lock provided by this utility model will now be described. The helmet lock is suitable for locking a helmet with a snap buckle 90, wherein a first locking tooth surface 101 is formed on the snap buckle 10 of the snap buckle 90. The helmet lock includes a lock housing 20, a locking member 30, an elastic torque member 302, and an unlocking component 4.

[0040] The lock housing 20 is used to fix it to the vehicle body and has a lock hole 201 for inserting the buckle 10. The lock housing 20 has an assembly cavity and a locking channel 202 adapted to the buckle 10. The locking member 30 is rotatably assembled in the assembly cavity and located on the side of the locking channel 202. The side of the locking member 30 near the locking channel 202 forms a second locking tooth surface 301.

[0041] The elastic torque member 302 is disposed on the locking member 30 to drive the locking member 30 to swing, so that the second locking tooth surface 301 approaches the locking channel 202. When the buckle 10 is inserted into place, the second locking tooth surface 301 presses against the first locking tooth surface 101 to lock the buckle 10. The unlocking component 4 is disposed in the assembly cavity and connected to the locking member 30. It is used to drive the locking member 30 to swing away from the locking channel 202 against the elastic force of the elastic torque member 302, so that the second locking tooth surface 301 disengages from the first locking tooth surface 101 to unlock the buckle 10.

[0042] It should be noted that the existing helmet buckle 90 has various structural forms. The helmet lock provided in this embodiment is adapted to the plug-in structure buckle 90, which includes a buckle body with a plug hole and a buckle body with a toothed surface, namely the buckle 10.

[0043] The aforementioned lock housing 20 can be fixed to any part of the vehicle body, such as the handlebars, front fork, rear fork, basket, etc. Considering that the helmet is more convenient and stable to place inside the basket, it is preferable to fix the lock housing 20 to the inner wall of the basket.

[0044] In this embodiment, after the locking member 30 is rotatably connected inside the lock housing 20, a torsion spring can be installed on its rotating shaft as an elastic torque member 302 to obtain elastic torque. Alternatively, a telescopic spring can be provided between the locking member 30 and the lock housing 20 at the part away from its rotating shaft to obtain elastic torque for the locking member 30.

[0045] In the initial state, the locking member 30 abuts against the inner wall of the lock housing 20 based on elastic torque. When the buckle 10 passes through the lock hole 201 and extends into the lock track 202 (the first locking tooth surface 101 must be inserted with the locking member 30 facing it; of course, the buckle 10 can also be inserted with the first locking tooth surface 101 on both sides, in which case the buckle 10 can be inserted into the lock hole 201 in any direction to achieve locking), the buckle 10 presses against the second locking tooth surface 301 and drives the locking member 30 to swing in the opposite direction against the elastic torque. This makes the buckle 10 form a unidirectional degree of freedom of movement similar to a ratchet pawl, that is, the buckle 10 can only be freely inserted into the lock hole 201, but it cannot be freely pulled out of the lock hole 201 due to the mutual engagement of the first locking tooth surface 101 and the second locking tooth surface 301. Once the buckle 10 is inserted into place, locking is completed.

[0046] In this embodiment, the unlocking component 4 can be electrically unlocked, such as by sending an unlocking command to the electronically controlled drive unit built into the lock housing 20 to make the unlocking component 4 operate automatically, or it can be manually unlocked, for example by using a keyhole provided on the lock housing 20 and an unlocking key. When unlocking, the key is inserted into the keyhole to drive the unlocking component 4 to operate. Whether it is electrically or manually unlocked, the unlocking is achieved by the action of the unlocking component 4 causing the locking member 30 to rotate so that the second locking tooth surface 301 disengages from the first locking tooth surface 101.

[0047] Compared with the prior art, the helmet lock provided in this embodiment uses the buckle 10 as part of the helmet buckle 90, and can also be inserted into the lock hole 201 to lock by the first locking tooth surface 101 engaging with the second locking tooth surface 301 on the locking member 30, without changing the structure of the helmet body. This avoids the impact of adding holes to the helmet body on structural strength. After the buckle 10 is inserted into the lock hole 201, the locking member 30 is driven by the elastic force of the elastic torsion member 302 to spring the second locking tooth surface 301. The first locking tooth surface 101 is pressed against the helmet, forming a surface-to-surface locking engagement. When the helmet needs to be used, the second locking tooth surface 301 is easily removed by swinging the locking member 30 through the unlocking component 4, thus separating it from the first locking tooth surface 101. The operation is simple and convenient. Compared with the existing technology of locking by inserting the locking tongue into the hole in the locking hole 201, the surface-to-surface locking method is more reliable and avoids the problem of reduced strength of the buckle 10 due to the opening. Both the helmet's structure and the buckle 90 structure ensure that the helmet's performance is not affected, and the helmet locking structure has high strength and reliability.

[0048] In some embodiments, see Figures 3 to 5The unlocking component 4 includes an unlocking drive 424 and a gear linkage mechanism 40; the unlocking drive 424 contacts the end of the locking component 30 away from its rotating assembly 31 when unlocking; the gear linkage mechanism 40 includes a motor 41 and a gear transmission assembly 42.

[0049] The unlocking drive member 424 is provided with spur teeth or racks, which are connected to the final gear 4212 of the gear transmission assembly 42 and are driven by the final gear. The unlocking drive member 424 drives the locking member 30 to swing by means of the gear linkage mechanism 40, so that the second locking tooth surface 301 moves closer to or away from the locking track 202.

[0050] When unlocking is required, the motor 41 transmits torque to the gear transmission assembly 42, and the last gear 4212 of the gear transmission assembly 42 drives the spur or rack of the unlocking drive 424 to convert the rotational motion into the linear motion of the unlocking drive 424, thereby causing the locking member 30 to swing to achieve unlocking. After unlocking, the motor 41 rotates in the opposite direction to make the locking member 30 automatically reset under elastic torque.

[0051] As an optional connection structure between the aforementioned unlocking drive component 424 and locking component 30, please refer to Figures 3 to 5 The locking member 30 has a movable groove 303 at one end away from its rotating assembly 31. The unlocking drive member 424 passes through the movable groove 303 at its end facing the locking member 30 and is provided with a baffle 4241. The baffle 4241 abuts against the side of the locking member 30 facing the lock track 202, and there is a movable gap between the unlocking drive member 424 and the groove wall of the movable groove 303.

[0052] Since the movement of the locking member 30 is oscillating, while the movement of the unlocking drive member 424 is linear, there needs to be a gap between the two when the unlocking drive member 424 drives the locking member 30 to oscillate, so as to accommodate the amount of movement of the locking member 30 in another direction other than the direction of movement of the unlocking drive member 424. Therefore, in this embodiment, the unlocking drive member 424 passes through the movable groove 303 and is provided with a baffle 4241. This allows the unlocking drive member 424 to pull the locking member 30 in one direction based on the contact between the baffle 4241 and the second locking tooth surface 301. At the same time, it also ensures that the locking member 30 can swing away from the first locking tooth surface 101 to overcome the elastic torque, thereby facilitating the insertion of the buckle 10 into the lock channel 202 to achieve locking.

[0053] Optionally, the gear transmission assembly 42 described above adopts, for example, Figure 4The structure shown includes a transmission gear set 421, a worm gear 422, and a worm wheel 423. The transmission gear set 421 is located inside the lock housing 20 and includes an input gear 4211 and a final stage gear 4212. The worm gear 422 is connected to the output end of the motor 41. The worm wheel 423 is coaxially connected to the input gear 4211 and meshes with the worm gear 422. The final stage gear 4212 meshes with the spur teeth or rack of the unlocking drive member 424, and one end of the rack is connected to the locking member 30.

[0054] The main function of the transmission gear set 421 is to reduce speed and increase torque. The purpose is to convert the high-speed, low-torque power transmitted from the motor 41 to the input gear 4211 through the cooperation of the worm 422 and worm wheel 423 into low-speed, high-torque power on its final gear 4212. Based on this, the final gear 4212 drives the unlocking drive 424 to move, and then the unlocking drive 424 drives the locking member 30 to swing to achieve unlocking. Because of the speed reduction and torque increase process of the worm wheel 423 and worm 422, as well as the speed reduction and torque increase process of the transmission gear set 421, the power requirements of the rotating power component can be reduced, which helps to use a smaller micro motor 41 as the rotating power component, thereby improving the structural compactness.

[0055] It should be noted that you should refer to [link / reference]. Figure 6 and Figure 7 A stacked gear set 425 is provided between the input gear 4211 and the final stage gear 4212. The stacked gear set 425 includes a first gear 4251 and a second gear 4252 that are coaxial. The first gear 4251 directly or indirectly meshes with the input gear 4211, and the second gear 4252 directly or indirectly meshes with the final stage gear 4212. Both the first gear 4251 and the second gear 4252 have meshing teeth 4253 on their end faces facing each other, and there is an elastic element (not shown in the figure) between the first gear 4251 and the second gear 4252. The elastic element is used to apply an axial elastic force to the first gear 4251 and the second gear 4252.

[0056] The stacked gear set 425 can be understood as multiple gears stacked axially. Here, the first gear 4251 and the second gear 4252 are coaxially stacked and an axial elastic force is applied between them using an elastic element such as a disc spring or spring. Based on this, the meshing teeth 4253 set on the opposite end faces of the first gear 4251 and the second gear 4252 achieve elastic meshing. In this way, the first gear 4251 can drive the second gear 4252 to rotate. When the axial movement of the rack reaches the limit position, the rotational resistance of the second gear 4252 increases instantaneously. At this time, the second gear 4252 and the first gear 4251 can overcome the axial elastic force of the elastic element and rotate relative to each other (the meshing teeth 4253 are circumferentially misaligned), thereby providing overload protection for the motor 41.

[0057] As a modified connection structure between the unlocking drive 424 and the locking member 30, the unlocking drive 424 can be connected to the locking member 30 via a pull wire. Thus, the unlocking drive 424 can unlock the locking member 30 by pulling the locking member 30 to swing, while at the same time, the slack of the pull wire can be used to give the locking member 30 the freedom to swing under the drive of the first locking tooth surface 101 to overcome the elastic torque, thereby meeting the requirement of the buckle 10 to freely insert into the locking channel 202 and ensuring the convenience of the locking operation.

[0058] It should be noted that, in this embodiment, as Figure 6 As shown, the end of the unlocking drive 424 that is away from the locking member 30 is provided with a locking trigger boss 4242. When the unlocking drive 424 moves to the position, it triggers the locking trigger boss 4242, and the motor 41 stops rotating.

[0059] By setting a proximity sensor on the side of the locking trigger boss 4242 away from the locking member 30 in the assembly cavity, when the unlocking drive 424 drives the locking member 30 to swing and complete the unlocking, the axial movement of the unlocking drive 424 causes the locking trigger boss 4242 to trigger the proximity sensor, and the motor 41 stops rotating.

[0060] For details, please refer to Figure 8 The upper part of the locking member 30 is a rotating assembly part 31, the middle part is provided with a second locking tooth surface 301, and the lower part extends an operating arm 32; wherein, the rotating assembly part 31 is assembled with the lock housing 20 through a rotating shaft, and an elastic torque member 302 is mounted on the rotating shaft, and the movable groove 303 is opened at the lower part of the operating arm 32.

[0061] The unlocking drive 424 acts on the operating arm 32, which is far from the rotating shaft. This ensures the length of the lever arm and reduces the power dependence on the unlocking drive 424, which is conducive to the unlocking driven by a low-power (low power means small size) motor 41, thereby improving the overall structural compactness.

[0062] For some possible embodiments, please refer to Figure 4 and Figure 5 The lock housing 20 is provided with a fixing plate 50. The fixing plate 50 and the second lock tooth surface 301 form a lock channel 202, which is aligned with the lock hole 201. The buckle 10 passes through the lock hole 201 and extends into the lock channel 202 to form a locking state. In the locking state, the side of the buckle 10 away from the locking member 30 abuts against the fixing plate 50.

[0063] When the buckle 10 is pulled away from the locking channel 202, the second locking tooth surface 301 abuts against the fixing plate 50 under the elastic force of the elastic torque member 302.

[0064] The fixing plate 50 can be a single-sided flat plate structure that is positioned opposite to the locking member 30 to form a gap. This gap serves as the locking channel 202 for the insertion of the buckle 10. Alternatively, the fixing plate 50 can be a three-sided grooved plate that forms a hole-shaped locking channel 202 with the locking member 30 for the insertion of the buckle 10. Considering the reliability of the insertion of the buckle 10 within the locking channel 202, the latter is preferred.

[0065] When the buckle 10 passes through the lock hole 201 and is inserted into the lock track 202, the plate surface opposite to the locking member 30 of the fixing plate 50 provides support for the buckle 10, thereby causing the second locking tooth surface 301 to press against the first locking tooth surface 101 under the elastic force of the elastic torque member 302, thereby realizing the elastic engagement of the second locking tooth surface 301 and the first locking tooth surface 101, ensuring a stable and reliable locking state.

[0066] Based on the above, see Figure 5 In this embodiment, the surface of the fixed plate 50 opposite to the second locking tooth surface 301 is an arc surface 501. The arc surface 501 is used to guide the buckle 10 to gradually approach the second locking tooth surface 301 when it is inserted into the locking channel 202.

[0067] The curved surface 501 serves two purposes: firstly, it guides the insertion of the buckle 10 into the locking channel 202, thereby improving operational convenience; secondly, it allows the locking channel 202 to gradually narrow from the opening inward, thus guiding the buckle 10 to gradually approach the locking member 30 during insertion into the locking channel 202. This ensures the tight contact between the second locking tooth surface 301 and the first locking tooth surface 101, preventing insufficient pressure between them from affecting the engagement stability and thus ensuring locking reliability.

[0068] In some embodiments, such as Figure 4 As shown, a locking sensor 60 is provided at the end of the locking channel 202 away from the lock hole 201; when the locking sensor 60 senses the buckle 10, it generates a successful locking signal and transmits it to the vehicle central control, and the locking member 30 approaches the buckle 10, and the second locking tooth surface 301 presses against the first locking tooth surface 101 to form a locking state.

[0069] When the buckle 10 is inserted into the lock hole 201, it presses against the locking sensor 60 and generates a locking success signal. The vehicle central control receives the locking success signal and sends it to the cloud. This electronic control method is mainly for the application scenario of shared bicycles. The method and principle of the control circuit sending signals to the cloud or receiving signals from the cloud are existing technologies and will not be described in detail here.

[0070] It should be noted that, for some shared bicycle-type bicycle markets, such as... Figure 3As shown, in this embodiment, the lock housing 20 is provided with an identification circuit 70, and the buckle 10 is provided with an identification chip 80; wherein, the identification circuit 70 is used to read the information of the identification chip 80 when the buckle 10 triggers the locking sensor 60.

[0071] The identification chip 80 on the buckle 10 stores identification information. When locking the helmet, after the buckle 10 is inserted into the lock channel 202, the identification circuit 70 can automatically recognize the information of the identification chip 80 and then generate a locking success signal to be uploaded to the cloud. When unlocking, the cloud sends an unlocking signal, and then the unlocking component 4 completes the unlocking action. Then the buckle 10 can be pulled out of the lock hole 201. At this time, the identification circuit 70 can no longer read the information of the identification chip 80 and can generate an unlocking success signal to be uploaded to the cloud. This identification application is also designed for the shared bicycle scenario. Its working principle is existing technology and will not be described in further detail here.

[0072] It should be noted that in this embodiment, the aforementioned proximity sensor, locking sensor 60, identification circuit 70, and identification chip 80 are all included in the helmet smart locking solution. Specifically, when the buckle 10 is inserted into the locking channel 202, it presses against the locking sensor 60; the identification circuit 70 reads the identification chip 30; and the locking trigger protrusion 4242 does not contact the contact sensor. When all three conditions are met, a locking success signal is obtained. During unlocking, the locking trigger protrusion 4242 presses against the contact sensor, allowing the buckle 10 to be pulled out of the locking channel 202. After the buckle 10 is fully pulled out, the unlocking drive 424 resets, the contact sensor loses pressure, the locking sensor 60 loses pressure, and the identification circuit 70 cannot read the identification chip 30. At this point, a locking success signal is generated.

[0073] Based on the same technical concept, this application also provides a cycling vehicle, including the aforementioned helmet lock.

[0074] It should be noted that the aforementioned riding vehicles can be household bicycles, electric vehicles, two-wheeled vehicles, three-wheeled vehicles, motorcycles, or shared bicycles and shared electric vehicles. Any vehicle that requires the wearing of a helmet is within the scope of riding vehicles mentioned in this application.

[0075] Compared with the prior art, the cycling vehicle provided in this embodiment adopts the aforementioned helmet lock. After the buckle 10 is inserted into the lock hole 201, the locking member 30, under the elastic force of the elastic torque member 302, drives the second locking tooth surface 301 to elastically press against the first locking tooth surface 101, thereby forming a surface-to-surface locking state. Compared with the prior art method of locking by inserting the locking tongue into the hole on the lock hole 201, the surface-to-surface locking method is more reliable and can avoid the problem of the buckle 10 losing strength due to the opening. Both the helmet's structure itself and the helmet's buckle 90 structure can ensure that the helmet's performance is not affected, and the helmet locking structure has high strength and reliability.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
