[0033] In the field of electric vehicle battery swapping, traditional battery swapping devices mostly use electrically driven mechanical structures to achieve battery replacement and locking. However, such structures contain numerous complex components and precision transmission systems, resulting in an overall complex structure. This complexity makes the assembly process between components cumbersome, requiring significant manpower and time, leading to low assembly efficiency. Simultaneously, the reliance on high-precision components and complex systems significantly increases the costs of research and development, production, and subsequent maintenance. In the search for a better battery swapping locking solution, simplifying the structure and avoiding the problems of low assembly efficiency and high costs caused by structural complexity has become an urgent technical challenge. This has also spurred the exploration and development of new structures such as the lock hole assembly 02 and the lock body assembly 01.
[0034] This embodiment provides a simple lock, such as Figure 1As shown, the simple lock may include a keyhole assembly 02 and a lock body assembly 01. The lock body assembly 01 may include a support unit 11, a drive unit 12, and a bolt unit 13, wherein the bolt unit 13 can pass through the support unit 11 and be rotatably connected to it. The drive unit 12 may include a drive rod 121, a left connecting module 122, and a right connecting module 123, wherein one end of the drive rod 121 is hinged to the support unit 11, and the other end extends away from the support unit 11. Figure 3 As shown, the left connecting module 122 may include a first left connecting rod 1221 and a second left connecting rod 1222. The drive rod 121, the first left connecting rod 1221, the second left connecting rod 1222, and a latch unit 13 are sequentially hinged together. The right connecting module 123 may include a first right connecting rod 1231 and a second right connecting rod 1232. The drive rod 121, the first right connecting rod 1231, the second right connecting rod 1232, and a latch unit 13 are sequentially hinged together. Through the hinged linkage transmission structure, one end of the drive rod 121 can be used as a handle for manual operation or a drive device can be provided to provide driving force, thereby converting the rotational motion of the drive rod 121 driven by a driving force into the synchronous rotation of the latch unit 13, achieving locking of the latch unit 13 and the lock hole assembly 02, simplifying the lock structure.
[0035] The simple lock can include an unlocked state and a locked state. In the unlocked state, the drive lever 121 is in a first position, and the bolt unit 13 and the lock hole assembly 02 are spaced apart, so that the bolt unit 13 and the lock hole assembly 02 are in a disengaged state. For example... Figure 2 As shown, the locked state can include the drive rod 121 being in the second position, with the latch unit 13 penetrating the lock hole assembly 02. The projection of the latch unit 13 in the extension direction of the latch unit 13 and the projection of the cavity of the lock hole assembly 02 in the extension direction of the latch unit 13 intersect, and the latch unit 13 and the lock hole assembly 02 abut against each other, restricting the lock hole assembly 02 from moving away from the latch unit 13. In the unlocked state, the drive rod 121 is driven to rotate from the first position to the second position. The first left connecting rod 1221 and the first right connecting rod 1231 can rotate with the drive rod 121. The second left connecting rod 1222 rotates with the first left connecting rod 1221, and the second right connecting rod 1232 rotates with the first right connecting rod 1231. The two latch units 13 rotate to the locked state with the second left connecting rod 1222 and the second right connecting rod 1232, respectively. The double latch unit 13 is controlled synchronously by a single drive rod 121, causing the latch unit 13 and the lock hole assembly 02 to engage. Compared with the electrically controlled locking structure, the structural cost is lower, and the purely mechanical control structure is simpler, easier to disassemble and maintain. The projected cross design of the latch unit 13 and the lock hole assembly 02 forms a mechanical self-locking mechanism.
[0036] In this embodiment, as Figure 1 and Figure 3 As shown, the support unit 11 may include a first support rod 111 and a first rotating hole 112. Two first rotating holes 112 can pass through the first support rod 111. The two first rotating holes 112 can be spaced apart, and the corresponding positions of the two first rotating holes 112 can be the midpoints of two opposite sides of the locked component (the locked component can be a battery box or a base tray), making the locking force evenly distributed and the locking more stable. The latch unit 13 can pass through the first rotating hole 112, and the latch unit 13 and the first rotating hole 112 can be rotatably connected. By providing a support rod with two first rotating holes 112, a stable rotation fulcrum is provided for the latch unit 13, while simultaneously making the locking state more stable.
[0037] In this embodiment, as Figure 1 and Figure 3 As shown, the support unit 11 may further include a second support rod 113 and a second rotating hole 114. The second support rod 113 and the first support rod 111 may be spaced apart and distributed at both ends of the locked component (which may be a battery box or a base). A second rotating hole 114 may pass through the second support rod 113. The latch unit 13 may pass through the second rotating hole 114, and the latch unit 13 and the second rotating hole 114 may be rotatably connected. The left connecting module 122 may further include a third left connecting rod 1223, a fourth left connecting rod 1224, and a fifth left connecting rod 1225. The third left connecting rod 1223 and the second left connecting rod 1222 may be connected, and the third left connecting rod 1223, the fourth left connecting rod 1224, the fifth left connecting rod 1225, and the latch unit 13 may be hinged sequentially. By adding the second support rod 113 to form a three-point support structure, the uniformity of the force distribution on the latch unit 13 is improved, and the shear strength in the locked state is increased.
[0038] In this embodiment, as Figure 1 and Figure 3As shown, the support unit 11 may include two second rotating holes 114. The two second rotating holes 114 can pass through the second support rod 113, and the two second rotating holes 114 can be spaced apart. The two first rotating holes 112 and the two second rotating holes 114 can be respectively located at corresponding positions at the four corners of the locked component (the locked component can be a battery box or a base tray), so that the force on the four locking tongue units 13 is even. The two locking tongue units 13 and the two second rotating holes 114 can be rotatably connected. The right connecting module 123 may also include a third right connecting rod 1233, a fourth right connecting rod 1234, and a fifth right connecting rod 1235. The third right connecting rod 1233 and the second right connecting rod 1232 can be connected. The third right connecting rod 1233, the fourth right connecting rod 1234, the fifth right connecting rod 1235, and a locking tongue unit 13 can be hinged sequentially; the third left connecting rod 1223, the fourth left connecting rod 1224, the fifth left connecting rod 1225, and a locking tongue unit 13 can also be hinged sequentially. The left and right limiting modules can be symmetrically arranged, and the fourth left connecting rod 1224 and the fourth right connecting rod 1234 can be located on the inner sides of the two long sides of the support unit 11, i.e., as shown... Figure 3 The inner side of the two dotted lines can be used to reduce the overall size of the simple lock and reduce the space it occupies.
[0039] In this embodiment, the left connecting module 122 may further include a left limiting post, which can be connected to the second left connecting rod 1222. The locking state may include the left limiting post and the first left connecting rod 1221 abutting against each other. Through the physical contact between the limiting post and the connecting rod, the rotation angle of the drive rod 121 during the locking process is limited to a certain range, ensuring that the locking tongue unit 13 reaches the preset locking position but does not exceed the limit position, thus preventing damage to the simple lock.
[0040] In this embodiment, the right connecting module 123 may further include at least one right limiting post, and the right limiting post and the second right connecting rod 1232 may be connected. The unlocked state may include the right limiting post and the first right connecting rod 1231 abutting against each other. The rotation angle of the drive rod 121 during the unlocking process is limited to a certain range to ensure that the bolt unit 13 reaches the preset unlocking position but does not exceed the limit position, thus preventing damage to the simple lock.
[0041] In this embodiment, as Figure 2As shown, the latch unit 13 may include a rotating rod 131 and a latch body 132. The rotating rod 131 can pass through the support unit 11. One end of one rotating rod 131 is rotatably connected to the second left connecting rod 1222, and the other end is connected to the corresponding latch body 132. One end of the other rotating rod 131 is rotatably connected to the second right connecting rod 1232, and the other end is connected to the corresponding latch body 132. The projected area of the latch body 132 in the extension direction of the rotating rod 131 can be larger than the projected area of the rotating rod 131, so that the latch body 132 will remain outside the first rotating hole 112 and the second rotating hole 114 and will not detach. The unlocked state may include the drive rod 121 being in a first position, with the latch body 132 and the lock hole assembly 02 spaced apart; the locked state may include the drive rod 121 being in a second position, with the rotating rod 131 passing through the lock hole assembly 02, the projection of the latch body 132 in the extension direction of the rotating rod 131 and the projection of the cavity of the lock hole assembly 02 in the extension direction of the rotating rod 131 intersecting, and the latch body 132 and the lock hole assembly 02 abutting against each other to restrict the lock hole assembly 02 from moving away from the latch unit 13.
[0042] This embodiment provides a base support, which may include any of the lock body assembly 01 or lock hole assembly 02 described in the above embodiments. For example... Figure 4 As shown, one type of base support may include any of the lock body components 01 described above, and may also include a base assembly 03. The base assembly 03 may include a base frame unit 31, a guide unit 32, and a connecting seat unit. The guide unit 32 and the base frame unit 31 can be connected; the connecting seat unit and the base frame unit 31 can also be connected. The base frame can be connected to the support unit 11. Another type of base support may include a lock hole assembly 02 and a base left key, and the lock hole assembly 02 can be connected to the lock body assembly 01. The connection between the guide unit 32 and the base frame ensures the positioning accuracy of the battery box and the base support, and the connecting seat unit enables the alignment of the power supply interface.
[0043] This embodiment provides a battery box, which may include any of the lock body assembly 01 or lock hole assembly 02 described in the above embodiments. The battery box may include any of the lock body assembly 01 described in the above embodiments, and may also include a battery frame assembly 04. The battery frame assembly 04 may include a battery frame unit 41 and a battery unit 42. The battery frame unit 41 and the battery box can be connected; the battery frame unit 41 can be connected to the support unit 11. Figure 5 As shown, another type of battery box may include a keyhole assembly 02 and a battery frame assembly 04. The battery box can be connected to the lock body assembly 01 through the keyhole assembly 02.
[0044] This embodiment provides a battery swapping system, which may include the base and battery box described in the above embodiment.
[0045] In a battery swapping system, such as Figure 6and Figure 4 As shown, the base includes a lock body assembly 01, a base frame unit 31, and a support unit 11 connected together; the battery box includes a lock hole assembly 02, which is connected to the battery frame unit 41. The battery swapping system includes an operating state. In the operating state, the base frame unit 31 and the battery frame unit 41 are in contact, a portion of the guide unit 32 extends into the internal cavity of the battery frame unit 41, the connecting seat unit is electrically connected to the battery unit 42, and the latch unit 13 and the lock hole assembly 02 are in a locked state, thus allowing the base with the lock body assembly 01 to be connected to the battery box with the lock hole assembly 02.
[0046] Alternatively, in another battery swapping system, the base includes a lock hole assembly 02, a base frame unit 31, and the lock hole assembly 02 are connected. The battery box includes a lock body assembly 01, a support unit 11, and a battery frame unit 41, which are connected. The battery swapping system includes an operating state.

[0047] The battery box and base locking interface are compatible with both forward and reverse installation modes through a bidirectional reversible component configuration.
[0048] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
