Abstract
Description
Technical Field
[0001] This application relates to the field of connection device technology, and in particular to a locking device and a transport device. Background Technology
[0002] Locks (locking devices) can connect two parts, two devices, etc. Some locking devices can movably connect two structural parts, while others can fix them in place. Over time, locking devices that fix two structural parts may loosen, thus requiring adjustment or maintenance. Utility Model Content
[0003] This application provides a locking device and a transport equipment that can automatically lock and fix two target parts and automatically adjust the connection gap.
[0004] On one hand, this application provides a locking device, which includes: a base, an actuating member, and a locking member; wherein, the base is used to be disposed on a first target member; the actuating member is rotatably disposed on the base about a first rotation center, and the actuating member has a pressing portion; the locking member is rotatably disposed on the base about a second rotation center, and the locking member has a limiting portion and a hooking portion, the limiting portion and the pressing portion are corresponding to each other and are both located on the same side of the rotation axis surface, and the hooking portion is located on the side of the rotation axis surface away from the limiting portion; the rotation axis surface is a virtual plane passing through the first rotation center and the second rotation center; when the locking member rotates from a first position to a second position about the second rotation center, the hooking portion can hook with the second target member, and the actuating member rotates from a third position to a fourth position about the first rotation center, so that the pressing portion abuts against the limiting portion, thereby restricting the locking member from rotating from the second position to the first position and restricting the relative movement between the second target member and the first target member.
[0005] The locking device provided in this application rotatably mounts the locking member on the base, and provides a limiting part and a hooking part on the locking member, with the limiting part and the hooking part located on opposite sides of the rotating shaft surface. Rotating the locking member allows the hooking part to engage with the second target member, facilitating the connection between the first target member, which is fixedly connected to the base, and the second target member. Furthermore, a toggle member is rotatably mounted on the base, and provides a pressing part corresponding to the limiting part. Rotating the locking member allows the pressing part to abut against the limiting part, thereby restricting the rotation of the locking member and preventing the hooking part from separating from the second target member. Simultaneously, with the limiting part and the pressing part located on the same side of the rotating shaft surface, when the distance between the first and second target members changes, rotating the pressing part towards the rotating shaft surface applies a force away from the rotating shaft surface to the limiting part, facilitating the movement of the hooking part towards the second target member. This ensures that the hooking part is always tightly engaged with the second target member, eliminating any gap between the locking device and the second target member. Therefore, the locking device provided in this application can automatically lock and fix two target parts, and can automatically adjust the connection gap.
[0006] In one possible implementation of this application, the angle formed by the sequential connection of the first rotation center, the contact point of the pressing part and the limiting part, and the second rotation center is greater than or equal to 90°.
[0007] In one possible implementation of this application, the locking member further includes a sliding portion located between the limiting portion and the engaging portion, extending from the second rotation center toward the first rotation center, and in the direction pointing from the second rotation center toward the first rotation center, the end of the sliding portion away from the second rotation center extends beyond the area where the actuating member is located; wherein, when the sliding portion contacts the second target member, the sliding portion causes the locking member to rotate from the first position to the second position under the action of the second target member.
[0008] In one possible implementation of this application, the side of the pressing part facing the sliding part has a sliding surface; during the process of the locking member rotating from the first position to the second position, the limiting part moves away from the free end in the second rotation and abuts against the sliding surface and slides relative to the sliding surface until the free end disengages from the sliding surface, and the pressing part abuts against the limiting surface of the limiting part facing the first rotation center.
[0009] In one possible implementation of this application, the sliding part and the hooking part surround each other to form a receiving groove that matches the second target member, and the receiving groove has an opening that matches the second target member.
[0010] In one possible implementation of this application, the actuating member further includes a actuating part, which is connected to the pressing part at an angle, and the actuating part can drive the actuating member to rotate between the third position and the fourth position.
[0011] In one possible implementation of this application, the locking device further includes a first reset member disposed between the base and the actuating member. The first reset member is used to apply a first force to the actuating member, which under the action of the first force tends to move from the third position to the fourth position, or is able to remain in the fourth position.
[0012] In one possible implementation of this application, the locking device further includes a second reset member disposed between the base and the locking member. The second reset member is used to apply a second force to the locking member, which under the action of the second force tends to move from the second position to the first position, or is able to remain in the first position.
[0013] In one possible implementation of this application, the locking device further includes an unlocking component connected to a toggle member. The unlocking component is disposed on the first target member and can drive the toggle member to rotate from the fourth position to the third position.
[0014] On the other hand, this application provides a transportation device, which includes: a power unit, a functional unit, and a locking device provided by any one of the above; wherein, the power unit is capable of moving on its own; the functional unit is adapted to the power unit and is used to carry the target object; the base of the locking device is disposed on the functional unit, and the power unit has a locking member that matches the hook portion of the locking member; the functional unit and the power unit are detachably connected through the cooperation of the hook portion and the locking member.
[0015] The transportation equipment provided in this application includes any of the locking devices provided above, which enables automatic locking and fixing of the power unit and the functional unit, and can automatically adjust the connection gap between the locking component and the locking fastener on the power unit, thereby improving the stability and reliability of the fixed connection between the power unit and the functional unit.
[0016] In one possible implementation of this application, the functional device has a first positioning part, and the power device has a second positioning part adapted to the first positioning part. The first positioning part and the second positioning part cooperate to limit the relative position of the functional device and the power device. Attached Figure Description

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.
[0034] In the embodiments of this application, 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 indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.
[0035] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.
[0036] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.
[0037] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0039] Locking devices include cabinet door locks and tailgate locks, which combine the lock body and the latch to secure two target components. Unlocking can be achieved by pulling a rope or using a motor to move an internal linkage within the lock body. In some related technologies, quick-release locks have many internal parts and complex structures, and the lock body itself lacks a tightening function. This requires using a soft material between the latch and the target component to loosen the locking gap, which cannot achieve rigid fixation of the two target components. Alternatively, manual maintenance can be used to adjust the gap between the latch and the target component, but this increases maintenance costs.
[0040] This application provides a locking device that can automatically lock and fix two target components and automatically adjust the connection gap. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 Schematic diagram of the locking device provided in this application Figure 1 , Figure 2 This is an exploded structural diagram of the locking device provided in this application. Figure 3 Schematic cross-sectional view of the locking device provided in this application Figure 1 , Figure 4 Schematic cross-sectional view of the locking device provided in this application Figure 2 , Figure 5 Schematic cross-sectional view of the locking device provided in this application Figure 3 The locking device provided in the embodiments of this application will be described below with reference to the examples in the accompanying drawings.
[0041] The locking device 1 provided in this embodiment includes: a base 11, an actuating member 12, and a locking member 13; wherein, the base 11 is used to be disposed on the first target member 4; the actuating member 12 is rotatably disposed on the base 11 about a first rotation center, and the actuating member 12 has a pressing part 121; the locking member 13 is rotatably disposed on the base 11 about a second rotation center, and the locking member 13 has a limiting part 131 and a hooking part 132, the limiting part 131 and the pressing part 121 are corresponding to each other and are both located on the same side of the rotating shaft surface M, and the hooking part 132 is located on the rotating shaft. The side of surface M away from the limiting part 131; the rotating shaft surface M is a virtual plane passing through the first rotation center and the second rotation center; when the locking member 13 rotates from the first position to the second position around the second rotation center, the hooking part 132 can hook with the second target member 5, and the actuating member 12 rotates from the third position to the fourth position around the first rotation center, so that the pressing part 121 abuts against the limiting part 131, thereby restricting the locking member 13 from rotating from the second position to the first position, and restricting the relative movement between the second target member 5 and the first target member 4.
[0042] In this embodiment, the base 11 can provide an installation foundation for other components in the locking device 1, and the locking device 1 can be installed on one of the two target parts that need to be fixedly connected through the base 11. For example, the base 11 can be fixed to the first target part 4 by riveting, threaded connection, snap-fit, etc. For example, the base 11 can be set as an approximately "U-shaped" box, or it can be set as a block, plate, etc. The specific structural shape of the base 11 is not limited in this embodiment.
[0043] In this embodiment, the actuating member 12 can lock or unlock the locking member 13. The actuating member 12 can be rotatably mounted on the base 11 so that the actuating member 12 can rotate relative to the base 11. For example, the actuating member 12 can be rotatably mounted on the base 11 by means of a rivet, pin, locking screw, etc., which serve as the first pivot 14. The axis of the first pivot 14 is also the first rotation center of the actuating member 12 relative to the base 11.
[0044] For example, the actuating member 12 can be configured to include a pressing portion 121 and a actuating portion 123. For instance, the actuating member 12 can be configured as an approximately "L-shaped" structure, with one arm of the "L-shaped" actuating member 12 serving as the pressing portion 121 and the other arm serving as the actuating portion 123. The included angle between the actuating portion 123 and the pressing portion 121 can be any angle between 60° and 120°, such as setting the included angle between the actuating portion 123 and the pressing portion 121 to 90° or a near-90° angle, so that the actuating portion 123 and the pressing portion 121 are connected at an angle. The first rotating shaft 14 can be set at the corner where the pressing part 121 and the actuating part 123 are connected. Then, by applying a force to the end of the actuating part 123 away from the first rotating shaft 14, the pressing part 121 can be driven to rotate relative to the locking member 13, so that the actuating member 12 can be driven to rotate between the third position and the fourth position by the actuating part 123.
[0045] In this embodiment, the locking member 13 is disposed on the base 11 and can be connected to the second target member 5 to fix the first target member 4 and the second target member 5 together. The locking member 13 can be rotatably disposed on the base 11 at a position corresponding to the actuating member 12. For example, the locking member 13 can be rotatably disposed on the base 11 by means of rivets, pins, locking screws, etc., which serve as the second pivot 15. The axis of the second pivot 15 is also the second rotation center of the locking member 13 relative to the base 11.
[0046] For example, the locking member 13 can be configured to include a limiting part 131 and an engaging part 132. The engaging part 132 can be configured to match the second target member 5, such as by having a groove. During the rotation of the locking member 13 around the second pivot 15, the groove on the engaging part 132 can hook onto or separate from the second target member 5. Figure 3 As shown, a limiting part 131 corresponding to the pressing part 121 can be provided on the locking member 13, and the second rotating shaft 15 is located between the limiting part 131 and the hook part 132. At the same time, the pressing part 121 and the limiting part 131 are both on the same side of the rotating shaft surface M, and the hook part 132 is located on the other side of the rotating shaft surface M. The rotating shaft surface M is a virtual plane passing through the axis of the first rotating shaft 14 and the axis of the second rotating shaft 15.
[0047] Another example, such as Figure 4 As shown, by setting the length of the pressing part 121 and the length of the limiting part 131, during the rotation of the actuating member 12 and the locking member 13 relative to the base 11, the pressing part 121 and the limiting part 131 can interfere with each other. That is, during the movement of both the pressing part 121 and the limiting part 131 towards the limiting surface 134, the pressing part 121 and the limiting part 131 will come into contact.
[0048] The locking member 13 and the actuating member 12 are configured as described in the example above, such as... Figure 4 and Figure 5 As shown, during the clockwise rotation of the locking member 13 around the second pivot 15, that is, during the process of the locking member 13 rotating from the first position around the second rotation center to the second position, the engaging part 132 can engage with the second target member 5, thereby restricting the clockwise rotation of the locking member 13 relative to the base 11. Figure 3 and Figure 5 As shown, after the locking member 13 rotates to the second position, the actuating member 12 can rotate clockwise around the first rotating shaft 14. That is, during the process of the actuating member 12 rotating from the third position to the fourth position around the first rotation center, the pressing part 121 will abut against the limiting part 131. By applying a clockwise force to the actuating part 123, the pressing part 121 can continue to move towards the rotating shaft surface M until the pressing part 121 and the limiting part 131 are tightly fitted and can no longer move towards the rotating shaft surface M. Then, the locking member 13 can be restricted to rotate counterclockwise by the actuating member 12, which can also restrict the locking member 13 from rotating from the second position to the first position, thereby fixing the second target member 5 and the first target member 4 together.
[0049] The locking device 1 provided in this embodiment of the application has a locking member 13 rotatably mounted on the base 11. The locking member 13 has a limiting part 131 and a hooking part 132, which are located on opposite sides of the rotating shaft surface M. Rotating the locking member 13 allows the hooking part 132 to engage with the second target member 5, facilitating the connection between the first target member 4, which is fixedly connected to the base 11, and the second target member 5. Furthermore, a toggle member 12 is rotatably mounted on the base 11, and a pressing part 121 corresponding to the limiting part 131 is provided on the toggle member 12. Rotating the locking member 13 causes the pressing part 121 to abut against the limiting part 131, thereby restricting the rotation of the locking member 13 and preventing the hooking part 132 from separating from the second target member 5. Simultaneously, with the limiting part 131 and the pressing part 121 both located on the same side of the rotating shaft surface M, when the distance between the first target member 4 and the second target member 5 changes, the pressing part 121 can be rotated towards the rotating shaft surface M to apply a force away from the rotating shaft surface M to the limiting part 131. This facilitates the movement of the engaging part 132 towards the second target member 5, ensuring that the engaging part 132 is always tightly engaged with the second target member 5, thereby eliminating the gap between the locking device 1 and the second target member 5. Therefore, the locking device 1 provided in this embodiment can automatically lock and fix the two target members and can automatically adjust the connection gap.
[0050] In some possible embodiments of this application, reference is made to Figure 6 and Figure 7 , Figure 6 Schematic cross-sectional view of the locking device provided in this application Figure 4 , Figure 7 Schematic cross-sectional view of the locking device provided in this application Figure 5 The angle formed by the sequential connection of the first rotation center, the contact point of the pressing part 121 and the limiting part 131, and the second rotation center is greater than or equal to 90°.
[0051] In this embodiment of the application, by setting the length of the pressing part 121 and the shape of the limiting part 131, after the pressing part 121 contacts the limiting part 131, a force can be applied to the actuating part 123 to make the pressing part 121 move a certain distance toward the rotating shaft surface M.
[0052] For example, the surface of the pressing portion 121 facing the limiting portion 131 can be configured as a convex arcuate surface, and correspondingly, the surface of the limiting portion 131 facing the pressing portion 121 can be configured as a concave arcuate surface. Thus, as... Figure 6 As shown, when the pressing part 121 and the limiting part 131 just come into contact, the first included angle R1 formed by the sequential connection of the first rotation center, the contact point between the pressing part 121 and the limiting part 131, and the second rotation center can be less than 90°. For example, the first included angle R1 can be 85°, 88°, etc. At this time, if the second target part 5 is separated from the first target part 4, the second target part 5 will drive the locking part 13 to rotate in the counterclockwise direction, and the pressing part 121 may rotate in the counterclockwise direction under the force applied by the limiting part 131.
[0053] like Figure 7 As shown, after the pressing part 121 and the limiting part 131 just come into contact, a clockwise force can be applied to the actuating part 123 so that the pressing part 121 continues to move towards the rotating shaft surface M. This allows the second included angle R2 formed by the sequential connection of the first rotation center, the contact point between the pressing part 121 and the limiting part 131, and the second rotation center to be equal to or greater than 90°. For example, the second included angle R2 can be 95°, 105°, etc. At this time, even if the second target member 5 is subjected to a force that separates it from the first target member 4, the second target member 5 will drive the locking member 13 to rotate in the counterclockwise direction. The pressing part 121 will also rotate in the counterclockwise direction under the force applied by the limiting part 131. Instead, the locking member 13 can be more stably restricted to the position where it engages with the second target member 5 by the actuating part 12.
[0054] In the above embodiments, since the contact point of the first rotation center, the pressing part 121 and the limiting part 131 and the second rotation center are connected in sequence, the included angle is greater than or equal to 90°. When the second target member 5 drives the locking part 13 to rotate in the counterclockwise direction, and the second target member 5 tends to separate from the hook part 132, the pressing part 121 tends to move towards the direction close to the rotating shaft surface M under the force applied by the limiting part 131. Thus, the hook part 132 can be driven to move towards the direction close to the second target member 5 through the limiting part 131, and the hook part 132 can be more stably restricted to the position of hooking with the second target member 5, which is beneficial to improving the stability and reliability of the locking device 1 in fixing the two target members.
[0055] In some possible embodiments of this application, such as Figure 4 As shown, the locking member 13 also includes a sliding part 133, which is located between the limiting part 131 and the hook part 132, and extends from the second rotation center toward the first rotation center. In the direction from the second rotation center toward the first rotation center, the end of the sliding part 133 away from the second rotation center extends beyond the area where the actuating member 12 is located. When the sliding part 133 contacts the second target member 5, the sliding part 133 causes the locking member 13 to rotate from the first position to the second position under the action of the second target member 5.
[0056] In this embodiment, a sliding portion 133 can be provided in the locking member 13 so that the second target member 5 can drive the locking member 13 to rotate relative to the base 11. For example, the locking member 13 can be configured as an approximately "T-shaped" structure, the limiting portion 131 and the hook portion 132 can be arranged along the same straight line, the sliding portion 133 can be disposed between the limiting portion 131 and the hook portion 132, and the sliding portion 133 can be located on the same side of the limiting portion 131 and the hook portion 132, thereby forming the locking member 13 into an approximately "T-shaped" structure.
[0057] For example, the second rotating shaft 15 can be positioned at the intersection of the limiting part 131, the engaging part 132, and the sliding part 133, and the sliding part 133 can extend from the second rotation center toward the first rotation center. The length of the sliding part 133 can be set such that it is greater than the distance between the first and second rotation centers, i.e., as shown... Figure 3 As shown, during the rotation of the sliding part 133 toward the first rotating shaft 14, the free end of the sliding part 133 is blocked by the actuating member 12 to restrict the rotation of the locking member 13 in the clockwise direction.
[0058] In another example, the sliding portion 133 and the engaging portion 132 enclose each other to form a receiving groove 135 that matches the second target member 5. The receiving groove 135 has an opening that matches the second target member 5. For example, a groove can be provided on the engaging portion 132 near the sliding portion 133 so that the sliding portion 133 and the engaging portion 132 enclose each other to form a receiving groove 135 that matches the second target member 5. The receiving groove 135 can be configured as a groove with a semi-circular cross-section, the opening of the receiving groove 135 facing the same direction as the extension direction of the sliding portion 133, and the opening width of the receiving groove 135 can be set to be greater than the diameter of the second target member 5 so that the second target member 5 can enter the receiving groove 135.
[0059] Another example, such as Figure 4 In the process of connecting the second target member 5 to the first target member 4, the locking member 13 can first be positioned relative to the base 11 in a first position (the locking member 13 is in an unlocked state). Then, the first target member 4 is moved closer to the second target member 5. During this process, the free end of the sliding part 133 will first abut against the second target member 5. As the distance between the first target member 4 and the second target member 5 decreases, the second target member 5 will drive the locking member 13 to rotate clockwise through the sliding part 133, which will cause the hooking part 132 to rotate closer to the second target member 5 until the groove wall of the receiving groove 135 clamps onto the second target member 5, that is, the hooking part 132 hooks with the second target member 5. Finally, the actuating member 12 is rotated so that the pressing part 121 abuts against the limiting part 131, thereby locking the locking member 13 and the second target member 5.
[0060] In the above embodiment, since a sliding portion 133 is provided on the locking member 13, and the length of the sliding portion 133 is greater than the distance between the first rotation center and the second rotation center, the rotation angle of the sliding portion 133 relative to the second rotation center can be limited by the actuating member 12. This limits the rotation range of the pressing part 121 driving the limiting part 131 towards the rotating shaft surface M. Furthermore, a receiving groove 135 matching the second target member 5 is provided between the sliding portion 133 and the hook portion 132. During the process of the second target member 5 driving the locking member 13 to rotate through the sliding portion 133, the receiving groove 135 can automatically clamp onto the second target member 5, thereby enabling the locking member 13 to automatically lock the second target member 5.
[0061] In some possible embodiments of this application, such as Figure 4 As shown, the pressing part 121 has a sliding surface 122 on the side facing the sliding part 133; during the process of the locking member 13 rotating from the first position to the second position, the free end of the limiting part 131 away from the second rotation center abuts against the sliding surface 122 and slides relative to the sliding surface 122 until the free end disengages from the sliding surface 122, and the pressing part 121 abuts against the limiting surface 134 of the limiting part 131 facing the first rotation center.
[0062] In this embodiment, the surface of the pressing part 121 facing the sliding part 133 can be configured as a sliding surface 122 that matches the limiting part 131. For example, the shape of the sliding surface 122 can be set according to the movement path of the free end of the limiting part 131 away from the second rotating shaft 15 when it rotates around the second rotating shaft 15. Since the path of the free end of the limiting part 131 away from the second rotating shaft 15 when it rotates around the second rotating shaft 15 is usually arc-shaped, the sliding surface 122 can be configured as a concave arc surface that matches the arc-shaped path of the free end of the limiting part 131 when it moves.
[0063] For example, such as Figure 4 and Figure 5 As shown, during the process of the locking member 13 rotating from the first position to the second position under the drive of the second target member 5, the free end of the limiting part 131 away from the second rotating shaft 15 can abut against the sliding surface 122 and slide relative to the sliding surface 122 until the free end of the limiting part 131 disengages from the sliding surface 122. The actuating member 12 rotates clockwise so that the pressing part 121 abuts against the limiting surface 134 of the limiting part 131 toward the first rotation center, thereby completing the locking of the locking member 13.
[0064] In the above embodiment, since the sliding surface 122 is provided on the side of the pressing part 121 facing the sliding surface 122, the free end of the limiting part 131 can slide against the sliding surface 122. During the rotation of the locking part 13 relative to the base 11, it is beneficial to reduce the swing of the actuating part 12 relative to the base 11.
[0065] In some possible embodiments of this application, such as Figure 2 and Figure 3 As shown, the locking device 1 also includes a first reset member 16, which is disposed between the base 11 and the actuating member 12. The first reset member 16 is used to apply a first force to the actuating member 12. Under the action of the first force, the actuating member 12 has a tendency to move from the third position to the fourth position, or can remain in the fourth position.
[0066] In this embodiment, the first reset member 16 can ensure that the actuating member 12 is always in close contact with the locking member 13. For example, the first reset member 16 can be a torsion spring, which can be sleeved on the first rotating shaft 14, with one cantilever of the torsion spring fixedly connected to the base 11, and the other cantilever of the torsion spring abutting the actuating part 123 of the actuating member 12 away from the pressing part 121. In this way, the torsion spring can always apply a first force to the actuating part 123, thereby making the pressing part 121 always tend to rotate towards the locking member 13. The first reset member 16 can also be a compression spring, a tension spring, an elastic rubber block, etc. The specific structure of the first reset member 16 is not limited in this embodiment.
[0067] In the above embodiment, since the actuating member 12 is provided with a first reset member 16, a first force can be applied to the actuating member 12 through the first reset member 16, so that the pressing part 121 always has a tendency to move closer to the limiting part 131. This allows the pressing part 121 to automatically abut against the limiting part 131 and press the limiting part 131 tightly. In turn, the limiting part 131 can drive the hook part 132 to move automatically closer to the second target member 5, thus realizing the automatic locking of the locking member 13 and the second target member 5, and automatically adjusting the distance between the locking member 13 and the second target member 5.
[0068] In some possible embodiments of this application, such as Figure 2 and Figure 3 As shown, the locking device 1 also includes a second reset member 17, which is disposed between the base 11 and the locking member 13. The second reset member 17 is used to apply a second force to the locking member 13. Under the action of the second force, the locking member 13 has a tendency to move from the second position to the first position, or can remain in the first position.
[0069] In this embodiment, the locking member 13 can be included in the unlocked state by means of the second reset member 17. For example, the second reset member 17 can be a torsion spring, which can be sleeved on the second rotating shaft 15, with one cantilever of the torsion spring fixedly connected to the base 11, and the other cantilever of the torsion spring abutting against the sliding part 133 of the locking member 13 on the side facing the actuating member 12. In this way, the torsion spring can always apply a second force to the sliding part 133, thereby making the sliding part 133 always have a tendency to rotate away from the actuating member 12. The second reset member 17 can also be a compression spring, a tension spring, an elastic rubber block, etc., and the specific structure of the second reset member 17 is not limited in this embodiment.
[0070] In the above embodiments, since a second reset member 17 is provided for the locking member 13, a second force can be applied to the locking member 13 through the second reset member 17, thereby ensuring that the locking member 13 always tends to move in the first position. Thus, after the second target member 5 is unlocked from the first target member 4, the locking member 13 can be held in the first position, which also means that the locking member 13 can be held in the unlocked position. When it is necessary to fix the second target member 5 and the first target member 4 together through the locking device 1, there is no need to adjust the position of the locking member 13, making it easier for the locking member 13 to directly contact the second target member 5, thus improving the ease of use of the locking device 1.
[0071] In some possible embodiments of this application, reference is made to Figure 8 , Figure 8 Schematic diagram of the locking device provided in this application Figure 2The locking device 1 also includes an unlocking component 18, which is connected to the toggle member 12. The unlocking component 18 is used to be mounted on the first target member 4. The unlocking component 18 can drive the toggle member 12 to rotate from the fourth position to the third position.
[0072] In this embodiment of the application, an unlocking component 18 can be provided in the locking device 1 so that the toggle member 12 can be operated by the unlocking component 18 to release the restriction of the toggle member 12 on the rotation of the locking member 13.
[0073] For example, the unlocking assembly 18 can be configured to include an unlocking member 181 and a connecting member 182. For instance, the unlocking member 181 can be configured to be rotatably mounted on the first target member 4, thereby allowing a portion of the unlocking member 181 to extend beyond the first target member 4. The unlocking member 181 can be movably connected to the toggle part 123 via the connecting member 182. For example, one end of the connecting member 182 can be rotatably connected to the end of the unlocking member 181 near the toggle member 12 using a rivet, locking screw, or the like, and the other end of the connecting member 182 can be rotatably connected using a rivet, locking screw, or the like. In this way, by applying force to the unlocking member 181, during the process of the unlocking member 181 rotating relative to the first target member 4, the connecting member 182 can drive the actuating member 12 to rotate relative to the base 11, thereby causing the pressing part 121 to rotate away from the limiting part 131 until the pressing part 121 separates from the limiting part 131, so as to complete the unlocking of the locking member 13 and the second target member 5.
[0074] In the above embodiments, since the locking device 1 is provided with an unlocking component 18, the unlocking component 18 can be installed on the first target part 4, so that the unlocking component 18 can drive the toggle part 12 to rotate relative to the locking part 13, which facilitates the unlocking of the first target part 4 and the second target part 5 that are fixedly connected by the locking device 1.
[0075] In addition, this application also provides a transportation device, referring to Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 , Figure 9 This is a structural schematic diagram of the first transportation device provided in this application. Figure 10 This is an exploded view of the first transportation equipment provided in this application.

[0076] In the embodiments of this application, such as Figure 10 and Figure 11 As shown, the power unit 2 can generate motion. For example, the power unit 2 includes a wheeled walking mechanism, a tracked walking mechanism, a footed walking mechanism, etc. The power unit 2 can be a balance scooter underbody including a secondary battery (a rechargeable battery), two hub motors, and tires. A locking element 21 that matches the hook part 132 can be provided on the power unit 2; for example, the connecting shaft connecting the hub motors and the main body of the power unit 2 can be used as the locking element 21.
[0077] In this embodiment, the functional device 3 can carry the target object and can be connected to the power device 2 to form a transportation device. For example, the functional device 3 can be the upper body of the balance scooter that matches the lower body of the balance scooter. The base 11 of the locking device 1 can be fixedly installed on the upper body of the balance scooter, thereby detachably connecting the upper body and the lower body of the balance scooter through the locking device 1.
[0078] For example, such as Figure 13 and Figure 14 As shown, the functional device 3 can be configured as a frame, and two driven wheels can be installed in the frame-type functional device 3. The locking device 1 can be installed on the frame. For example, the base 11 can be fixed to the frame by welding, snap-fitting, threaded connection, etc. Then, the frame and the power device 2 can be detachably connected by the engagement of the hook part 132 and the locking fastener 21.
[0079] In another example, the unlocking member 181 can be fixedly connected to the connecting member 182, and the connecting member 182 can be fixedly connected to the toggle part 123, so that a rotational force can be applied to the toggle member 12 through the unlocking member 181. The embodiments of this application do not limit the specific structure of the functional device 3.
[0080] The transportation equipment provided in this application includes the locking device 1 provided in any of the above embodiments. Therefore, it can automatically lock and fix the power unit 2 and the functional unit 3, and can automatically adjust the connection gap between the locking member 13 and the locking member 21 on the power unit 2, which is beneficial to improving the stability and reliability of the fixed connection between the power unit 2 and the functional unit 3.
[0081] In some possible embodiments of this application, such as Figure 10 and Figure 13 As shown, the functional device 3 has a first positioning part 31, and the power device 2 has a second positioning part 22 adapted to the first positioning part 31. The first positioning part 31 and the second positioning part cooperate to limit the relative position of the functional device 3 and the power device 2.
[0082] In this embodiment, a first positioning part 31 can be provided on the functional device 3, and a second positioning part 22 can be provided on the power device 2. The relative positions of the functional device 3 and the power device 2 can be limited by the cooperation of the first positioning part 31 and the second positioning part 22. For example, the second positioning part 22 can be configured as a groove or a through hole, and the first positioning part 31 can be configured as a protrusion that matches the groove or through hole. During the connection of the functional device 3 and the power device 2, the first positioning part 31 can be inserted into the second positioning part 22 to achieve positioning of the functional device 3 and the power device 2.
[0083] In the above embodiments, since the functional device 3 has a first positioning part 31 and the power device 2 has a second positioning part 22 adapted to the first positioning part 31, the functional device 3 and the power device 2 can be quickly positioned through the cooperation of the first positioning part 31 and the second positioning part 22. Furthermore, after the functional device 3 and the power device 2 are fixedly connected by the locking device 1, the first positioning part 31 and the second positioning part 22 can provide more connection points for the functional device 3 and the power device 2, which is beneficial to improving the connection strength between the functional device 3 and the power device 2.
