Description

Technical Field

[0001] This disclosure relates to the field of battery swapping, and in particular to a lock body, locking mechanism, locking method, and unlocking method. Background Technology

[0002] Currently, the battery box of an electric vehicle needs to be securely locked to the load-bearing area of ​​the electric vehicle, while during automatic battery swapping, the battery box needs to be easily and quickly unlocked or locked to the electric vehicle.

[0003] Existing locking mechanisms use a snap-fit ​​connector to connect the lock head and lock body. A nut rotates relative to the connector, pulling it along its length to lock the battery box to the vehicle body. During the snap-fit ​​process, the connector rotates to adjust its position, thus locking or unlocking. However, during this rotation, external resistance may cause the connector to malfunction, preventing it from rotating to the preset angle and resulting in the locking or unlocking mechanism failing. Summary of the Invention

[0004] In view of the above, it is necessary to provide a lock body, a locking mechanism, a locking method, and an unlocking method, which are designed to control the position of the connector and prevent the battery box from failing to lock or unlock.

[0005] Therefore, this disclosure first provides a lock body, comprising:

[0006] A connecting assembly includes a connector and a rotating component, wherein the connector and the rotating component are threadedly connected;

[0007] The stop assembly includes a first stop member and a second stop member, wherein the first stop member is connected to the connecting member and the second stop member is connected to the rotating member;

[0008] When the rotating member rotates and drives the connecting member to move along the length direction, the connecting member drives the first stop member to move to the position connecting the second stop member, and then the rotating member drives the connecting member to rotate through the first stop member and the second stop member.

[0009] According to the lock body, when the connecting member moves the first stop to the position of contacting the second stop, the first stop and the second stop are connected by the friction between the first stop and the second stop.

[0010] According to the lock body, at least one of the opposing sides of the first stop and the second stop is provided with friction texture.

[0011] According to the lock body, at least one of the first stop and the second stop has magnetic force. When the connecting member moves the first stop to a position close to the second stop, the first stop and the second stop are connected by magnetic force between the first stop and the second stop.

[0012] According to the lock body, the first stop is a protrusion that connects to the bottom of the connecting member and protrudes radially; the second stop is the contact surface of the rotating member facing the protrusion. When the connecting member moves the first stop to a position contacting the second stop, the protrusion contacts the contact surface of the rotating member. Preferably, the protrusion is conical, and the contact surface is a conical surface corresponding to the protrusion.

[0013] In addition, this disclosure also provides a locking mechanism, including:

[0014] The lock body described above includes a first snap-fit ​​member that connects to the connector;

[0015] The lock head includes a second locking member; when the first stop member is connected to the second stop member, the rotating member drives the connecting member to rotate through the first stop member and the second stop member, and then drives the first locking member to rotate relative to the second locking member through the connecting member.

[0016] According to the locking mechanism, the lock head further includes a stop portion, which is used to stop the first latching member from continuing to rotate when the first latching member and the second latching member are rotated to the unlock position, and to stop the first latching member from continuing to rotate when the first latching member and the second latching member are rotated to the lock position.

[0017] According to the locking mechanism, the second latching member includes a bearing portion and an entry channel, and the first latching member includes a locking rod and a latching portion. The latching portion is connected to the locking rod and extends in the radial direction of the connector, and is used to rotate to a locking position to latch the bearing portion after passing the bearing portion along the entry channel.

[0018] According to the locking mechanism, the second snap-fit ​​member is provided with a snap-fit ​​groove for receiving the snap-fit ​​portion, and the supporting portion is the snap-fit ​​groove.

[0019] This disclosure further provides a locking method, including the following steps:

[0020] The rotating component is connected to the second stop component via the first stop component, thereby driving the connecting component to rotate. The connecting component drives the first locking component to rotate relative to the second locking component.

[0021] When the first and second latching members rotate to the locked position, the first latching member is stopped, thereby stopping the rotation of the connecting member;

[0022] The rotating member rotates relative to the connecting member, causing the connecting member to move along the length direction, and the connecting member causes the snap-fit ​​portion of the first snap-fit ​​member to hook onto the bearing portion of the second snap-fit ​​member.

[0023] According to the locking method, before the rotating member drives the connecting member to rotate by connecting the second stop member through the first stop member, the method further includes: the first locking member and the second locking member moving towards each other until the locking part of the first locking member passes over the bearing part of the second locking member.

[0024] When the first latching member and the second latching member are rotated to the locked position, the first latching member is stopped by a stop portion.

[0025] This disclosure also provides a method for unlocking the device, including the following steps:

[0026] The rotating component rotates relative to the connecting component, causing the connecting component to move along the length direction. The connecting component causes the first snap-fit ​​component to move away from the second snap-fit ​​component, and the connecting component causes the first stop component to move closer to the second stop component.

[0027] When the first stop moves to the position connecting the second stop, the first latching member and the second latching member have a preset distance along the length direction of the connecting member;

[0028] The rotating component drives the connecting component to rotate via the first stop and the second stop, and the connecting component drives the first latching component to rotate relative to the second latching component to the unlocked position.

[0029] According to the unlocking method, when the connector drives the first latching member to rotate relative to the second latching member to the unlock position, the method further includes: the first latching member being stopped by a stop part, and the connector being stopped from rotating by the first stop part.

[0030] According to the unlocking method, after the connector drives the first latching member to rotate relative to the second latching member to the unlocking position, the method further includes: the latching portion of the first latching member moves along the entry channel of the second latching portion until it disengages from the second latching portion through the entry channel.

[0031] Compared with existing technologies, the above-mentioned lock body, locking mechanism, locking method and unlocking method, by setting a first stop and a second stop between the connecting member and the rotating member, allow the rotating member to drive the connecting member to rotate through the connecting force between the first stop and the second stop, so as to rotate the connecting member to the unlocking position or the locking position. The structure is simple and effectively reduces the production cost of the locking mechanism. Attached Figure Description

[0044] The following detailed embodiments will further illustrate this disclosure in conjunction with the above-described drawings. Detailed Implementation

[0045] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this disclosure; the described embodiments are merely a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0047] In various embodiments, for ease of description and not limitation of this disclosure, the term "connection" used in the patent application specification and claims is not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0048] In the field of battery swapping, the battery box is connected to the vehicle body. To prevent the battery box from moving on the vehicle body, a locking mechanism is needed to lock it to the vehicle body. Under normal use, the locking mechanism is in the locked state, fixing the battery box to the vehicle body. When it is necessary to replace the battery box, external force is used to activate the locking mechanism, switching it from the locked state to the unlocked state. At this time, the battery box can detach from the vehicle body under its own weight or the action of the battery swapping equipment.

[0049] Figure 1 This is a schematic diagram of the locking structure, such as... Figure 1As shown, the locking mechanism includes a lock head 10 and a lock body, used to lock the battery box to a fixing member. The fixing member can be a vehicle body, a battery rack, or other components for mounting the battery box. The locking mechanism includes a lock head 10 and a lock body. As an example, in this embodiment, the lock head 10 is mounted on the battery box, and the lock body is mounted on the fixing member. However, this embodiment is not limited to this; the lock head 10 can also be connected to the fixing member, and the lock body can also be mounted on the battery box. Those skilled in the art can set the mounting positions of the lock head 10 and the lock body as needed. Furthermore, the movement of the lock head 10 and the lock body does not affect the structure of the locking mechanism. Specifically, when the battery box needs to be placed on the vehicle body, the battery box moves downwards until the lock head 10 and the lock body engage. That is, when the lock body is stationary, the lock head 10 moves towards the lock body until the lock head 10 and the lock body engage, thereby locking the battery box to the fixing member and preventing the battery box from detaching from the fixing member or shaking. In other embodiments, the battery box can be lifted by a battery swapping device, that is, the lock body moves toward the lock head 10 while the lock head 10 is stationary. This application does not limit this.

[0050] Figure 2 This is a structural diagram of lock cylinder 10. (See diagram below.) Figure 1 and Figure 2 As shown, the lock head 10 includes an upper mounting plate 11 and a lower mounting plate 12, which are arranged generally parallel to each other. Two connecting posts are also provided between the upper mounting plate 11 and the lower mounting plate 12 as stop portions 13. In this embodiment, the lock head 10 also includes a second snap-fit ​​member for snapping into the lock body. The term "snap-fit" refers to a connection method formed by the mutual hooking of two connecting parts.

[0051] Figure 3 This is a schematic diagram of the lock body. Figure 4 This is a schematic diagram of the lock body in its disassembled state. (Example:) Figure 3 and Figure 4 As shown, the lock body includes a lock shell 30, a first latching member, a connecting assembly, and a stop assembly. The first latching member corresponds to the second latching member and is used to mate with the second latching member to achieve a latching connection between the lock head 10 and the lock body. The connecting assembly is used to pull the first latching member and the second latching member to move relative to each other to lock the lock head 10 and the lock body. The stop assembly is used to stop the rotation of the connecting assembly.

[0052] Figure 5 This is a structural diagram of the first and second card connectors. (See diagram below.) Figures 1-5 As shown, the first and second locking components are used to engage the lock head 10 and the lock body. That is, when the lock head 10 and the lock body move toward each other to a preset position, the first and second locking components hook each other, so that the lock head 10 and the lock body are engaged through the first and second locking components.

[0053] In this embodiment, such as Figure 2 and Figure 5 As shown, the second snap-fit ​​member includes a support portion 21 and an entry channel 22. In this embodiment, the support portion 21 is the side of the lock head 10 away from the lock body. In this embodiment, the second snap-fit ​​member is provided with a snap-fit ​​groove 121 for receiving the snap-fit ​​portion 23, and the support portion 21 is preferably the inner wall of the snap-fit ​​groove 121. The entry channel 22 of the second snap-fit ​​member is a strip-shaped through hole that passes through the second mounting plate of the lock head 10. In other embodiments, the entry channel 22 can also be a non-circular hole of other shapes, such as a cross-shaped or plum blossom-shaped through hole, so that after the second snap-fit ​​member passes through the entry channel 22, it can be rotated at a preset angle to snap onto the support surface to achieve a snap-fit ​​connection.

[0054] like Figure 4 and Figure 5 As shown, the first locking member includes a locking rod 20 and a locking portion 23. In this embodiment, the locking rod 20 is coaxially connected to the connector 60 of the connecting assembly and is integrally formed with the connector 60. However, those skilled in the art can provide locking rods 20 of other shapes, or locking rods 20 can be provided separately, so that the connector 60 can drive the locking rod 20 to rotate when rotating, thus completing the locking action. The locking portion 23 is connected to the locking rod 20 and extends along the radial direction of the locking rod 20 for hooking onto the bearing portion 21. In this embodiment, there can be two locking portions 23, each extending along the radial direction of the locking rod 20 to form a "T"-shaped structure with the locking rod 20. However, in other embodiments, the locking portion 23 can also have other shapes, such as a plum blossom shape, a cross shape, or a rice-shaped structure. Depending on the relative position between the locking portion 23 and the entry channel 22, the locking portion 23 has a locked position and an unlocked position during rotation.

[0055] like Figure 5 As shown, the solid line indicates the locking position of the latching part 23. The locking position refers to the position where the latching part 23 rotates to at least partially overlap with the bearing part 21 along the length of the locking rod 20. Preferably, the latching part 23 is positioned perpendicular to the length direction of the entry channel 22. Figure 5 The position is shown as being located within the snap-fit ​​groove 121. When the snap-fit ​​part 23 is in the locked state, the snap-fit ​​part 23 is first in the locked position, and then the snap-fit ​​part 23 is pulled closer to the support part 21 until the snap-fit ​​part 23 abuts against the support part 21 within the snap-fit ​​groove 121. Figure 5The dotted line indicates the unlocked position of the latching part 23. The unlocked position is where the latching part 23 corresponds to the entry channel 22, allowing it to move along the entry channel 22 until the lock head 10 disengages from the lock body, or, alternatively, allowing it to move along the entry channel 22 past the support part 21. Those skilled in the art will understand that the positions of the first and second latching parts can also be interchanged; that is, the first latching part connects to the lock head 10, and the second latching part connects to the lock body. Those skilled in the art can configure the connection structure of the first and second latching parts as needed.

[0056] To control the rotation angle between the first and second latching components, the lock head 10 has two stop portions 13, spaced 90 degrees apart along the circumference, located in the locked and unlocked positions respectively. The stop portions 13 prevent the first latching component from continuing to rotate when both components are in the unlocked position, and also prevent the first latching component from continuing to rotate when both components are in the locked position. Therefore, the function of the stop portions 13 is to prevent unidirectional rotation of the first latching component, allowing it to rotate between the unlocked and locked positions.

[0057] Figure 6 This is a cross-sectional view of the locking mechanism in the unlocked state. Figure 7 This is a cross-sectional view of the locking mechanism in the locked state. For example... Figure 6 and Figure 7 As shown, the connecting assembly includes a connector 60 and a rotating member 40, which are used to drive the first snap-fit ​​member to move along the axial direction (i.e., the length direction of the connector 60) to lock the battery box and the fixing member.

[0058] The connector 60 is generally rod-shaped and includes at least a threaded section 61. One end of the connector 60 is coaxially connected to the locking rod 20, and the other end is axially movable to the lock housing 30 and extends into the lock housing 30. The rotating member 40 is located within the lock housing 30 and rotatably connected to the lock housing 30. The rotating member 40 is threadedly connected to the connector 60 at the threaded section 61, and the rotation of the rotating member 40 relative to the connector 60 drives the connector 60 to move along its length.

[0059] The stop assembly includes a first stop 50 and a second stop 51. The first stop 50 is connected to the connecting member 60, and the second stop 51 is connected to the rotating member 40. When the rotating member 40 rotates and drives the connecting member 60 to move along its length, the connecting member 60 drives the first stop 50 to the position connected to the second stop 51. Then, the rotating member 40 drives the connecting member 60 to rotate via the first stop 50 and the second stop 51. Thus, through the relatively weak connecting force of the first stop 50 and the second stop 51, the rotating member 40 can drive the connecting member 60 to rotate together with minimal resistance. The connecting member 60 then drives the first latching member to rotate, adjusting the angle between the first and second latching members, thereby switching between the unlocked and locked positions. Then, since the first locking member is stopped by the stop part 13 after rotating to the target position and cannot continue to rotate, at this time, the driving force of the rotating member 40 is greater than the weaker connecting force between the first stop member 50 and the second stop member 51, so the rotating member 40 can continue to be driven to rotate relative to the connecting member 60, and the connecting member 60 is pulled to move along the length direction, so as to achieve precise control of the movement of the connecting member 60.

[0060] Those skilled in the art will understand that the connection force between the first stop 50 and the second stop 51 can be achieved in various ways. In this embodiment, the first stop 50 is a protrusion that connects to the bottom of the connector and protrudes radially. It is coaxially connected to the bottom of the connector 60 by screws, and the protrusion protrudes radially from the connector 60. The second stop 51 is the end face of the bottom of the rotating member 40 (i.e., the contact surface that contacts the protrusion). The connector 60 drives the first stop 50 to move to a position that contacts the second stop 51. The first stop 50 abuts against the second stop 51, and the first stop 50 and the second stop 51 are connected by the frictional force between them. In this embodiment, the first stop 50 is a cylinder, but in some other embodiments, the first stop 50 can be a cone, with its side facing the second stop 51 being a conical surface; correspondingly, in this embodiment, the second stop 51 is the lower end surface of the rotating member 40, which is a plane, but in some other embodiments, the second stop 51 can also be a conical surface, i.e., a conical cavity, used to accommodate and dock with the first stop 50, thereby achieving a frictional connection with the first stop 50.

[0061] To improve the friction between the first stop 50 and the second stop 51, in some embodiments, friction textures may be provided on at least one of the opposing sides of the first stop 50 and the second stop 51 to enhance the friction during contact. However, those skilled in the art will understand that the first stop 50 can also achieve a "weak" connection with the second stop 51 in other ways. For example, at least one of the first stop 50 and the second stop 51 may have magnetic force. When the connecting member 60 moves the first stop 50 to a position close to the second stop 51, the first stop 50 and the second stop 51 are connected by the magnetic force between them. Thus, when the first stop 50 is connected to the second stop 51, the rotating member 40 drives the connecting member 60 to rotate via the first stop 50 and the second stop 51, and then the connecting member 60 drives the first snap-fit ​​member to rotate to the position where it snaps into the second snap-fit ​​member.

[0062] Figure 8 This is a flowchart of the locking method, which is described below. Figure 8 Describe in detail the locking method implemented by the above-mentioned locking mechanism. For example... Figure 8 As shown, the locking method includes steps S801 to S804. In the initial state, the first stop 50 and the second stop 51 are in a connected state, that is, the first stop 50 and the second stop 51 are in contact with each other under certain pressure, and the rotating member 40 can drive the connecting member 60 to rotate through the first stop 50 and the second stop 51.

[0063] Step S801: The first card connector and the second card connector move toward each other in the unlocked position until the card connector portion 23 of the first card connector passes over the carrier portion 21 of the second card connector.

[0064] Step S802: The rotating member 40 drives the connecting member 60 to rotate due to the friction between the first stop member 50 and the second stop member 51. The connecting member 60 drives the first locking member to rotate relative to the second locking member until the first and second locking members rotate to the locked position. At this time, the locking portion 23 of the first locking member is located above the bearing portion 21, and the locking portion 23 of the first locking member is stopped by the stop portion 13, thereby stopping the rotation of the connecting member 60, so that the connecting member 60 can no longer rotate.

[0065] Step S803: The rotating member 40 continues to rotate with a force greater than that between the first stop member 50 and the second stop member 51. At this time, the rotating member 40 rotates relative to the connecting member 60, causing the connecting member 60 to move along the length direction.

[0066] Step S804: The connector 60 drives the snap-fit ​​part 23 of the first snap-fit ​​part to hook the bearing part 21 of the second snap-fit ​​part, pulling the lock head 10 and the lock body to move towards each other, locking the battery box onto the fixing part, and completing the locking action.

[0067] Figure 9 This is a flowchart of the unlocking method, combined with the following... Figure 9 Describe in detail the unlocking method implemented by the above locking mechanism. For example... Figure 9 As shown, the unlocking method includes steps S901 to 905. In the initial state, the latching portion 23 of the first latching member presses against the supporting portion 21 of the second latching portion 23. At this time, on the one hand, due to the large friction between the latching portion 23 and the supporting portion 21, it cannot rotate directly and needs to be unlocked after the latching portion 23 moves away from the supporting portion 21 for a certain distance; on the other hand, in order to prevent the latching portion 23 from rotating on its own under the action of external force and entering the unlocked position, in some embodiments, the supporting portion 21 is set in the latching groove 121. Therefore, when unlocking, it is also necessary to first move the latching portion 23 away from the supporting portion 21 for a certain distance (at least greater than the depth of the latching groove 121) before unlocking. In addition, there is a certain distance between the first stop portion 13 and the second stop portion 13, and there is no connecting force between them.

[0068] Step S901: The rotating member 40 rotates relative to the connecting member 60, causing the connecting member 60 to move along its length. Since there is no contact between the first stop member 50 and the second stop member 51 in the initial state, there is no friction between them; simultaneously, the connecting member 60 is pressed into the locking groove 121 by the locking part 23 and cannot rotate. Therefore, when the rotating member 40 rotates, its movement is relative to the connecting member 60.

[0069] Step S902: During the movement of the connecting member 60 along its length, it drives the first locking member to move away from the second locking member. Simultaneously, the connecting member 60 also drives the first stop member 50 to move closer to the second stop member 51. Specifically, driven by the rotating member 40, the connecting member 60 moves along... Figure 7 The upward movement shown causes the locking part 23 to move upward and disengage from the contact of the bearing part 21; on the other hand, it causes the first stop 50 to move closer to the second stop 51 (i.e., closer to the bottom end face of the rotating part 40).

[0070] Step S903: When the first stop 50 moves to the position connecting the second stop 51, the first and second latching members have a preset distance along the length direction. At this time, the first stop 50 abuts against the second stop 51, and the latching part 23 disengages from the latching groove 121 and can rotate.

[0071] Step S904: The rotating member 40 drives the connecting member 60 to rotate via the first stop member 50 and the second stop member 51. The connecting member 60 drives the first latching member to rotate relative to the second latching member to the unlocked position. After reaching the unlocked position, the connecting member 60 is stopped by the stop part 13 via the first latching member. Thus, the connecting member 60 cannot continue to rotate, and the rotating member 40 cannot continue to drive the connecting member 60 to rotate. That is, the rotation of the rotating member 40 is blocked, thereby confirming that the connecting member 60 has rotated to the unlocked position. The unlocked position is where the latching part 23 of the first latching member corresponds to the entry channel 22 of the second latching part 23.

[0072] Step S905: The first latching part 23 moves along the entry channel 22 of the second latching part 23 until it disengages from the second latching part through the entry channel 22, thus completing the entire unlocking action.

[0073] The aforementioned lock body, locking mechanism, locking method, and unlocking method utilize a first stop 50 and a second stop 51 between the connecting member 60 and the rotating member 40. The rotating member 40 can drive the connecting member 60 to rotate through the connecting force between the first stop 50 and the second stop 51, thus rotating the connecting member 60 to the unlocked or locked position. In application, only the first stop 50 and the second stop 51 need to be set between the connecting member 60 and the rotating member 40 to achieve precise control of the rotation and movement of the connecting rod. This not only simplifies the structure and effectively reduces the production cost of the locking mechanism, but also facilitates operation and improves the problem of the connecting member 60 being jammed or rotating unevenly during rotation and movement.
