Technical Field

[0001] The present invention relates to a vehicle lock, and particularly to a mechanical lock and a shared bicycle. Background Art

[0002] At present, most of the common locked vehicle locks on the market are locks driven by an electric motor to unlock. Moreover, there is even a situation where a fake lock mode is used to "lock" the vehicle.

[0003] Driving to unlock or lock the vehicle by an electric motor has a relatively high cost. Also, due to its own structure and other reasons, the failure rate of this kind of lock is very high. For example, once the electric motor fails, the user cannot operate to return or pick up the vehicle. In the case of "locking" in the fake lock mode, the vehicle is not actually locked, so there are potential safety risks and the vehicle is extremely easy to be stolen.

[0004] Therefore, the technicians in this field are committed to developing a mechanical lock and a shared bicycle that can allow users to quickly return and pick up the vehicle, with high reliability, low cost, and being economical and practical. Summary of the Invention

[0012] Optionally, in the above mechanical lock, the fixed component and the first guiding component are integrally formed.

[0013] Optionally, in the above mechanical lock, the outer peripheral edge of the surface of the fixed component facing the movable component is the same as that of the surface of the movable component facing the fixed component.

[0014] Optionally, in the above mechanical lock, a first groove is formed on the surface of the movable component facing the fixed component, and / or a second groove is formed on the surface of the fixed component facing the movable component, and the first elastic component is located in the first groove or the second groove.

[0020] In addition, to achieve the above object, in another technical solution of the present invention, a shared vehicle is further provided, which has any one of the mechanical locks involved in the above technical solutions.

[0021] The mechanical lock and the shared bicycle provided by the present invention have the following technical effects:

[0022] 1. Since there is no need to use a motor drive, there is no need to set up a complex motor linkage mechanism. Compared with the structure using a motor drive, its own structure is simple.

[0024] 3. From the appearance, the lock body is a box that is roughly square, and the appearance is simple. Therefore, there are no special requirements for the installation part of the mechanical lock, and the installation versatility is high and the adaptability is strong.

DETAILED DESCRIPTION OF THE INVENTION

[0033] The following describes the implementation manners of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0034] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0035] A mechanical lock according to an embodiment of the present invention includes: a lock body provided with a first chamber and a second chamber that communicate with each other; a first guiding member that can be inserted into the first chamber; a movable member sleeved on the first guiding member and capable of moving along the first guiding member; a fixed member provided at one end of the first guiding member and opposite to the movable member; a first elastic member provided on the first guiding member and located between the fixed member and the movable member; and a second guiding member provided in the second chamber and capable of freely extending into the first chamber.

[0036] Next, a mechanical lock according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0037] Figure 1 is a three-dimensional exploded schematic view of the mechanical lock of this embodiment. Refer to Figure 1 As shown, in the mechanical lock of this embodiment, the lock body 1 is assembled from two symmetric lock body components. For the convenience of understanding and description, only half of the lock body 1 is shown in Figure 2 、 Figures 4 - 6 , that is, only one lock body component is shown in Figure 2 、 Figures 4 - 6 , and the other is omitted from the illustration.

[0038] In this embodiment, the mechanical lock includes: a lock body 1, a first guiding member 2, a fixing member 3, a second guiding member 4, a movable member 5, a first elastic member 6, and a stopper 8. Among them, the fixing member 3 is fixedly provided at one end in the longitudinal direction of the first guiding member 2; the movable member 5 is disposed opposite to the fixing member 3 on the first guiding member 2 and is arranged to be freely movable along the longitudinal direction of the first guiding member 2; the first elastic member 6 is disposed on the first guiding member 2 and is arranged to be freely expandable and contractible along the longitudinal direction of the first guiding member 2, and is located between the fixing member 3 and the movable member 5; the stopper 8 is fixedly provided on the first guiding member 2 and is located on the side of the movable member 5 opposite to the first elastic member 6, that is, on the side of the movable member 5 away from the fixing member 3; the lock body 1 is provided with a first chamber 1A and a second chamber 1B. The first chamber 1A is for inserting the first guiding member 2, and the second chamber 1B communicates with the first chamber 1A; and the second guiding member 4 is disposed in the second chamber 1B and can freely extend into the first chamber 1A.

[0039] In addition, both the first chamber 1A and the second chamber 1B of the lock body 1 are cylindrical. In this embodiment, the first chamber 1A of the lock body 1 is cylindrical, and one end thereof opens to the outer surface of the lock body 1, that is, an opening is formed on the outer surface of the lock body 1, and the first guiding member 2 is inserted into the first chamber 1A from the opening. The second chamber 1B of the lock body 1 is cylindrical, one end thereof communicates with the first chamber 1A, and the axial direction of the second chamber 1B is perpendicular to the axial direction of the first chamber 1A. That is, the first chamber 1A and the second chamber 1B communicate with each other and form a T-shaped structure.

[0040] In addition, from the external shape, the lock body 1 of this embodiment is a substantially square box body, which is assembled by docking two lock body components.

[0041] In this embodiment, the first guiding member 2 is a rod-shaped member with a circular cross-section. Therefore, the longitudinal direction of the above-mentioned first guiding member 2 refers to the axial direction of the first guiding member 2. Therefore, in the following description, it will also be referred to as the axial direction or the axial direction of the first guiding member 2.

[0042] In addition, the first guiding member 2 of this embodiment is a rod-shaped member with a circular cross-section, but this does not constitute a limitation to the present invention. As long as it can meet the assembly requirements of the fixing member 3, the first elastic member 6, the movable member 5, and the stopper 8, there is no special requirement for its shape.

[0043] The fixing member 3 is fixedly provided at the said one end of the first guiding member 2 and functions as a striker in the unlocking and locking operations of the mechanical lock.

[0044] Optionally, the fixing member 3 is a conical body or a hemispherical body, and is arranged such that the central axis direction of the conical body or the hemispherical body is the same as the axial direction of the first guiding member 2, and the bottom surface of the conical body or the hemispherical body faces the first elastic member 6. Further, the top end of the fixing member 3 can also be arranged as a flat surface, which can not only reduce the sharp part to improve safety, but also reduce the size of the fixing member 3, thereby reducing the overall size of the mechanical lock.

[0045] For example, in the present embodiment, the fixing member 3 is a hemispherical body with its top end machined into a flat surface. However, compared with the bottom surface of the hemispherical body, the flat surface machined from the top end of the hemispherical body has a smaller area, so the bottom surface of the hemispherical body is also referred to as the bottom surface with a larger area. Moreover, the fixing member 3 is arranged such that its axial direction is the same as the axial direction of the first guiding member 2, the flat surface machined on the top end faces the opposite side of the first guiding member 2, and its bottom surface with a larger area faces the first elastic member 6. That is to say, the fixing member 3 gradually becomes thicker in the axial direction of the first guiding member 2 from one end of the first guiding member 2 to the other end, and the outer peripheral surface of the fixing member 3 is a surface inclined with respect to the axial direction of the first guiding member 2.

[0046] With such a configuration, during the locking process, the outer peripheral surface of the fixing member 3 can cooperate with the component serving as the lock tongue to smoothly achieve the locking operation.

[0047] In addition, in the present embodiment, the fixing member 3 and the first guiding member 2 are formed separately, but this does not limit the present invention. In other embodiments, the fixing member 3 can also be integrally formed with the first guiding member 2. In the case where the fixing member 3 and the first guiding member 2 are integrally formed, not only the number of components can be reduced, but also the assembly process of the mechanical lock can be reduced, which is more beneficial to the management of product quality and the reduction of production costs.

[0048] The movable member 5 can be frustum-shaped or truncated-cone-shaped, and is arranged such that the central axis direction of the frustum-shaped or truncated-cone-shaped body is the same as the axial direction of the first guiding member 2, and the bottom surface with a larger area of the frustum-shaped or truncated-cone-shaped body faces the first elastic member 6.

[0049] For example, in the present embodiment, the movable member 5 is truncated-cone-shaped, which has a bottom surface with a larger area and a bottom surface with a smaller area. Moreover, the movable member 5 is arranged such that the bottom surface with a smaller area faces the other end of the first guiding member 2, and the bottom surface with a larger area faces the first elastic member 6. That is to say, the movable member 5 gradually becomes thinner in the axial direction of the first guiding member 2 from one end of the first guiding member 2 to the other end, and the outer peripheral surface of the movable member 5 is a surface inclined with respect to the axial direction of the first guiding member 2.

[0050] With such a configuration, during the unlocking process, the outer peripheral surface of the movable member 5 can cooperate with the component serving as the locking tongue to smoothly achieve the unlocking operation.

[0051] In addition, in the present embodiment, the large bottom surface of the fixed member 3 is disposed opposite to the large bottom surface of the movable member 5. Preferably, the outer peripheral edge of the surface of the fixed member 3 facing the movable member 5 is the same as the outer peripheral edge of the surface of the movable member 5 facing the fixed member 3, that is, the outer circles of these two surfaces are of the same size and can completely coincide.

[0052] Since during the unlocking process, after the fixed member 3 and the movable member 5 are attached, the attached portion is completely coincident without steps, it is possible to ensure that the unlocking operation is smoother, more stable and reliable.

[0053] Optionally, a first groove that sinks along the axial direction of the first guiding member 2 is formed on the surface of the movable member 5 facing the fixed member 3, and the first groove is used to accommodate the first elastic member 6. In the present embodiment, the surface of the movable member 5 facing the fixed member 3 is also the surface of the movable member 5 facing the first elastic member 6. When the movable member 5 moves towards the fixed member 3, the first elastic member 6 is compressed. When the movable member 5 moves to the fixed member 3, the first elastic member 6 is fully accommodated in the first groove of the movable member 5, so that the movable member 5 can be fully attached to the fixed member 3.

[0054] Similarly, it may also be that a second groove that sinks along the axial direction of the first guiding member 2 is formed on the surface of the fixed member 3 facing the movable member 5, and the second groove is used to accommodate the first elastic member 6. In the present embodiment, the surface of the fixed member 3 facing the movable member 5 is also the surface of the fixed member 3 facing the first elastic member 6. When the movable member 5 moves towards the fixed member 3, the first elastic member 6 is compressed. When the movable member 5 moves to the fixed member 3, the first elastic member 6 is fully accommodated in the second groove of the fixed member 3, so that the movable member 5 can be fully attached to the fixed member 3.

[0055] In addition, it may also be that a first groove that sinks along the axial direction of the first guiding member 2 is formed on the surface of the movable member 5 facing the fixed member 3, and a second groove that sinks along the axial direction of the first guiding member 2 is formed on the surface of the fixed member 3 facing the movable member 5. Thus, when the movable member 5 moves towards the fixed member 3, the first elastic member 6 is compressed. When the movable member 5 is attached to the fixed member 3, the first groove of the movable member 5 and the second groove of the fixed member 3 jointly form a receiving space for receiving the first elastic member 6, that is, a part of the first elastic member 6 is received in the movable member 5 and the other part is received in the fixed member 3.

[0056] In the present embodiment, the fixed member 3, the first elastic member 6, the movable member 5, and the stopper 8 are sequentially assembled on the first guiding member 2 starting from the one end portion of the first guiding member 2. That is to say, the first elastic member 6 is disposed between the fixed member 3 and the movable member 5. Therefore, the surface of the fixed member 3 facing the movable member 5 is also the surface facing the first elastic member 6, and the surface of the movable member 5 facing the fixed member 3 is also the surface facing the first elastic member 6.

[0057] In the present embodiment, the stopper 8 is an annular member that is sleeved on the outer peripheral surface of the first guiding member 2 and fixedly disposed on the first guiding member 2. The function of the stopper 8 is to limit the movement of the movable member 5 in the axial direction of the first guiding member 2, thereby preventing the movable member 5 and even the first elastic member 6 from coming loose from the other end portion of the first guiding member 2. The fixing method of the stopper 8 on the first guiding member 2 can be threaded connection, pin connection, or key connection. However, this does not constitute a limitation to the present invention. As a variant, the stopper 8 can also be fixedly disposed on the first guiding member 2 by means of hot fitting or the like. Regarding the connection method between the stopper 8 and the first guiding member 2, there is no special requirement, as long as stable and firm assembly can be achieved.

[0058] In addition, in the present embodiment, the stopper 8 being an annular member is only for illustrative purposes and does not constitute a limitation to the present invention. The stopper 8 can also be set in other shapes, as long as it can abut against the movable member 5 to limit the movement of the movable member 5 toward the other end portion of the first guiding member 2.

[0059] Furthermore, in the same way as in the case of the fixed member 3, the stopper 8 and the first guiding member 2 can also be integrally formed. In the case where the stopper 8 is integrally formed on the first guiding member 2, both the number of components can be reduced and the assembly process of the mechanical lock can be reduced, which is more conducive to the management of product quality and the reduction of production costs.

[0060] In addition, regarding the setting position of the stopper 8, in the present embodiment, the first guiding member 2 is further provided with a stepped portion corresponding to the setting position of the stopper 8. Specifically, the shaft diameter of the portion where the stopper 8 is installed is smaller than the shaft diameter of the portion where the first elastic member 6 and the movable member 5 are installed, and at least a part of the surface of the stopper 8 facing the movable member 5 is in contact with the stepped surface of the stepped portion. Thus, the stopper 8 can be further fixed by the stepped portion to prevent the stopper 8 from moving toward the one end portion of the first guiding member 2.

[0061] In addition, the top end of the second guiding member 4 has an inclined end face, which is inclined with respect to the length direction of the second guiding member 4. In addition, in the present embodiment, since the second guiding member 4 is a rod-shaped member with a circular cross-section, the above-mentioned length direction of the second guiding member 4 refers to the axial direction of the second guiding member 4. Therefore, in the following description, it will also be referred to as the axial direction or the axial direction of the second guiding member 4.

[0062] Furthermore, in the present embodiment, the inclined end face of the second guiding member 4 is disposed opposite to the opening of the first chamber 1A. When the first guiding member 2 is inserted into the first chamber 1A, it will contact the inclined end face of the second guiding member 4.

[0063] Optionally, a limiting block 403 is provided on the second guiding member 4, and a limiting groove 103 corresponding to the limiting block 403 is provided on the second chamber 1B, thereby restricting the movement of the second guiding member 4 in the second chamber 1B.

[0064] In the present embodiment, the limiting block 403 of the second guiding member 4 is two lugs protruding radially from the outer peripheral surface of the second guiding member 4, and the limiting groove 103 of the second chamber 1B is an annular groove portion formed corresponding to the lugs. The limiting groove 103 and the limiting block 403 cooperate to play a limiting role, thereby restricting the movement of the second guiding member 4 in the second chamber 1B.

[0065] Specifically, the limiting block 403 of the second guiding member 4 is embedded in the limiting groove 103 of the second chamber 1B and can move back and forth between a first position and a second position in the second chamber 1B along the axial direction of the second guiding member 4 (which is also the axial direction of the second chamber 1B). When the limiting block 403 moves to the first position of the limiting groove 103, the extending length of the second guiding member 4 extending into the first chamber 1A is the largest. Thus, for example, the length of the second guiding member 4 extending into the first chamber 1A in the unlocked state can be restricted by the setting of the first position. When the limiting block 403 moves to the second position of the limiting groove 103, the second guiding member 4 is completely received in the second chamber 1B. Thus, sufficient advancing and retreating space is provided for the second guiding member 4 to ensure the smooth progress of the unlocking operation and the locking operation.

[0066] In addition, preferably, the size of the inclined end face is set such that when the second guiding member 4 is in the first position, that is, when the length extending into the first chamber 1A is the largest, a part of the inclined end face still remains in the second chamber 1B.

[0067] In the present embodiment, the first elastic member 6 is a spring member, which is sleeved on the outer peripheral surface of the first guiding member 2 and can freely expand and contract.

[0068] Preferably, the first elastic member 6 is arranged to be in a compressed state in the unlocked state. Specifically, when the movable member 5 moves to the side of the stopper 8 and contacts the stopper 8, the first elastic member 6 is also compressed and sandwiched between the fixed member 3 and the movable member 5, and its two ends respectively press against the fixed member 3 and the movable member 5. Therefore, the first elastic member 6 in the compressed state applies a force to the movable member 5, causing the movable member 5 to abut against the stopper 8.

[0069] In the present embodiment, the second elastic member 7 is a spring member, which is sleeved on the outer peripheral surface of the second guiding member 4 and can freely expand and contract.

[0070] Preferably, the second elastic member 7 is arranged to be in a compressed state in the unlocked state. That is to say, even when there is no force pushing the second guiding member 4 into the interior of the second chamber 1B, the second elastic member 7 is also compressed. Therefore, the second elastic member 7 applies a force to the second guiding member 4, causing the second guiding member 4 to be held in the first position. In this case, the length of the second guiding member 4 extending into the first chamber 1A is the largest.

[0071] In addition, in the present embodiment, the second elastic member 7 is arranged by a pair of oppositely arranged spring seats. Among them, one spring seat is arranged on the stepped portion of the second guiding member 4, and the other spring seat is arranged on the stepped portion of the second chamber 1B. Correspondingly, when the one spring seat is arranged on the second guiding member 4, a reduced-diameter portion with a smaller diameter is formed therewith. The second elastic member 7 is restricted between the pair of oppositely arranged spring seats, sleeved on the reduced-diameter portion of the second guiding member 4, and can freely expand and contract.

[0072] Furthermore, as long as the length of the second elastic member 7 in the natural state, that is, the state of not being compressed or stretched, is greater than the distance between the above-mentioned pair of spring seats, then the second elastic member 7 will be in a compressed state after being assembled. Therefore, it can also be said that the second elastic member 7 is in a compressed state in the unlocked state.

[0073] In addition, regarding the material, the materials of the first guiding member 2, the fixed member 3, the movable member 5, and the stopper 8 are all metals, preferably stainless steel. However, this is only an example and does not constitute a limitation to the present invention. In other embodiments, resins, rubbers, etc. can also be used as materials according to factors such as the operating requirements of the mechanical lock. In addition, the materials of the first elastic member 6 and the second elastic member 7 can be freely selected according to requirements such as the elastic coefficient, for example, it can be stainless steel.

[0074] Hereinafter, for the convenience of description, the first guiding member 2 and the fixed member 3, the first elastic member 6, the movable member 5, and the stopper 8 assembled on the first guiding member 2 are collectively referred to as the first assembly.

[0075] Next, the locking process of the mechanical lock of this embodiment will be described. In the locked state, the first component is inserted into the first chamber 1A, and the top end of the second guiding member 4 is located between the fixed member 3 and the movable member 5. From this, it can also be known that in this embodiment, the top end having an inclined end face functions as a locking tongue.

[0076] When the first component starts to be inserted into the first chamber 1A, first, the inclined end face of the second guiding member 4 contacts the fixed member 3.

[0077] Next, since the outer peripheral surface of the fixed member 3 is inclined with respect to the axial direction of the first guiding member 2, when the first component continues to be inserted along the first chamber 1A, the outer peripheral surface of the fixed member 3 slides past the top end of the second guiding member 4 and applies a thrust to the second guiding member 4. The second guiding member 4 is pushed into the interior of the second chamber 1B, and the pushing of the second guiding member 4 further compresses the second elastic member 7. When the fixed member 3 completely passes by the second guiding member 4, the thrust applied by the fixed member 3 to the second guiding member 4 disappears. At this time, the compressed second elastic member 7 rebounds and releases an elastic force, causing the second guiding member 4 to pop out and reset, that is, the second guiding member 4 extends outwards from the second chamber 1B again.

[0078] Furthermore, as described above, during the locking process, the second guiding member 4 has not yet applied a force to the movable member 5, and there is still the first elastic member 6 between the fixed member 3 and the movable member 5. At this time, the fixed member 3 and the movable member 5 are still not in contact. Therefore, before the second guiding member 4 extending out from the second chamber 1B enters between the fixed member 3 and the movable member 5, the locking operation is completed.

[0079] That is to say, only by inserting the first component into the first chamber 1A of the lock body 1 can the locking operation be completed.

[0080] Next, the unlocking process of the mechanical lock of this embodiment will be described. In the unlocked state, the first component and the lock body 1 are two separate parts. In the first component, the fixed member 3 and the movable member 5 are not in contact, and there is the first elastic member 6 between them. Moreover, the first elastic member 6 is in a compressed state, and the movable member 5 abuts against the stopper 8 under the action of the elastic force of the first elastic member 6; the second guiding member 4 is located at the first position in the second chamber 1B, that is, the position where the length extending into the first chamber 1A is the largest.

[0081] First, continue to push the first component into the interior of the first chamber 1A. The movable member 5 comes into contact with the inclined end surface of the second guiding member 4. Specifically, the outer periphery of the bottom surface with a larger area of the movable member 5 comes into contact with the inclined end surface of the second guiding member 4. Since the inclined end surface of the second guiding member 4 is inclined with respect to the axial direction of the second guiding member 4, as the first component is continuously pushed inward, the outer periphery of the bottom surface with a larger area of the movable member 5 slides over the inclined end surface of the second guiding member 4 and applies a thrust to the second guiding member 4. The second guiding member 4 is pushed toward the interior of the second chamber 1B. The pushing of the second guiding member 4 further compresses the second elastic member 7 until the outer periphery of the bottom surface with a larger area of the movable member 5 passes over the top end of the second guiding member 4.

[0082] After the outer periphery of the bottom surface with a larger area of the movable member 5 passes over the top end of the second guiding member 4, the top end of the second guiding member 4 comes into contact with the outer peripheral surface of the movable member 5. Since the outer peripheral surface of the movable member 5 tapers from one end of the first guiding member 2 to the other end, the thrust applied by the movable member 5 to the second guiding member 4 weakens, and the second guiding member 4 starts to rebound and reset under the action of the elastic force of the second elastic member 7. That is, the second guiding member 4 rebounds from the second chamber 1B to the first chamber 1A again.

[0083] Next, pull the first component outward from the lock body 1. The outer peripheral surface of the movable member 5 comes into contact with the top end of the second guiding member 4. As the first component is continuously pulled outward, the outer peripheral surface of the movable member 5 slides over the top end of the second guiding member 4 and applies a thrust to the second guiding member 4. The second guiding member 4 is pushed toward the interior of the second chamber 1B. The pushing of the second guiding member 4 further compresses the second elastic member 7. At the same time, as the first component is pulled outward, the movable member 5 also receives a force applied by the second guiding member 4. The movable member 5 moves closer to the fixed member 3 while applying a pushing force to the first elastic member 6, and this pushing force compresses the first elastic member 6 until the movable member 5 fits against the fixed member 3.

[0084] Moreover, the outer periphery of the fitting surface between the movable member 5 and the fixed member 3 completely coincides. After the movable member 5 fits against the fixed member 3, the first elastic member 6 is received in the first groove of the movable member 5 and / or the second groove of the fixed member 3.

[0085] Then, after the fitting portion of the movable member 5 and the fixed member 3 passes over the top end of the second guiding member 4, the top end of the second guiding member 4 contacts the outer peripheral surface of the fixed member 3. Since the outer peripheral surface of the fixed member 3 gradually becomes thicker from one end portion of the first guiding member 2 to the other end portion, that is, the inclination of the outer peripheral surface of the fixed member 3 is in line with the inclination of the inclined end surface of the second guiding member 4, the first assembly is no longer blocked by the second guiding member 4 and can be freely taken out from the first chamber 1A. At the same time, since the movable member 5 is no longer subjected to the acting force applied by the second guiding member 4, the movable member 5 no longer applies a pushing force to the first elastic member 6, and the compressed first elastic member 6 rebounds and releases an elastic force, pushing the movable member 5 away toward the stopper 8 side. The movable member 5 abuts against the stopper 8 under the action of the first elastic member 6.

[0086] That is to say, in order to open the mechanical lock of the present embodiment, it is only necessary to first push the first assembly into the first chamber 1A of the lock body 1 and then pull it out of the first chamber 1A of the lock body 1 to complete the unlocking operation.

[0087] According to the mechanical lock described above, during the locking operation, it can be achieved only by inserting the first assembly into the lock body 1; during the unlocking operation, it can be achieved only by first pushing it inward and then pulling it outward. The locking operation and the unlocking operation are both very simple. In addition, the structure is simple, the movement of each component is smooth, so it has high reliability and low cost.

[0088] In addition, as an application example of the present embodiment, the above mechanical lock is used on a shared vehicle that can be paired with a vehicle return pile. Specifically, the first assembly of the above mechanical lock, that is, the first guiding member 2 successively installed with the fixed member 3, the first elastic member 6, the movable member 5 and the stopper 8, is installed on a shared vehicle such as a bicycle or an electric assist bicycle, and the lock body 1 installed with the second guiding member 4 and the second elastic member 7 is installed on the vehicle return pile of the shared vehicle.

[0089] When the user returns the vehicle, inserting the first assembly into the lock body 1 locks (secures) the mechanical lock, and the shared vehicle is locked on the vehicle return pile. When the user picks up the vehicle, pulling the first assembly out of the lock body 1 unlocks the mechanical lock, and the shared vehicle can be freely taken out.

[0090] In addition, in another embodiment of the present invention, a shared vehicle is further provided, which has a mechanical lock related to the above embodiment.

[0091] For the purpose of illustration, some exemplary embodiments of the present invention have been described. It should be understood that the present invention can be implemented in other ways not specifically shown in the drawings.
