[0117] The rotating member 120 may refer to a component that can rotate around its own axis in the receiving hole 111. The rotating member 120 rotates and drives the locking member 130 connected thereto to rotate, thereby driving the locking portion 132 of the locking member 130 to rotate. The rotating member 120 may be a columnar structure, and the rotating member 120 and the receiving hole 111 are clearance-matched to facilitate the rotation of the rotating member 120.

[0118] The locking member 130 may refer to a member for locking two members. The locking member 130 includes a rod 131 and a locking member 132. The rod 131 may refer to a rod-shaped member in the locking member 130 connected to the rotating member 120; the locking member 132 may refer to a portion in the locking member 130 used to lock the two members.

[0121] In actual use, the first fixing portion 13 has a penetration hole 1301, and the second fixing portion 1400 has a locking hole 1401 that matches the shape of the locking portion 132. When the connecting lock 100 is in an unlocked state, the rod portion 131 is penetrated through the penetration hole 1301, and the locking portion 132 passes through the locking hole 1401. Then, the rotating member 120 is rotated, and under the guidance of the guide protrusion 112 and the guide groove 1311, the rotating member 120 drives the locking portion 132 of the locking member 130 to rotate until the locking portion 132 is staggered with the locking hole 1401, that is, the locking hole 1401 is locked. 01 will not fall out of the locking hole 1401, the first fixing part 13 and the second fixing part 1400 are locked, at this time, the connecting lock 100 is in a locked state, thereby achieving the fixation of the battery 1100 in the vehicle 1000; when the battery 1100 needs to be replaced, the rotating member 120 is rotated again, the locking part 132 is reset, so that the locking part 132 can be moved out of the locking hole 1401, and the locking of the first fixing part 13 and the second fixing part 1400 is released. At this time, the battery 1100 can be taken out of the vehicle 1000, so that the battery 1100 can be replaced. Of course, in other embodiments, the through hole 1301 can also be provided in the second fixing part 1400, and the locking hole 1401 is provided in the first fixing part 13.

[0122] The connecting lock 100 of the embodiment of the present application, by arranging the guide protrusion 112 on the hole wall of the receiving hole 111 of the lock sleeve 110, and arranging the guide groove 1311 on the outer peripheral surface of the rod portion 131 of the locking member 130, makes it unnecessary to arrange an opening for the guide protrusion 112 to enter the guide groove 1311 on the end surface of the lock sleeve 110, thereby improving the sealing performance of the connecting lock 100, reducing the risk of lubricating substances in the connecting lock 100 and external water vapor, impurities and other substances entering the receiving hole 111 and causing problems such as wear and rust, improving the reliability and service life of the connecting lock 100, and also conducive to improving the reliability of the battery 1100 installed in the electrical device, and can also reduce the replacement frequency of the connecting lock 100 and reduce the maintenance cost of the electrical device.

[0123] Combination Fig.14 As shown, Fig.14 A connection lock 100 provided in another embodiment of the present application is provided along Figure 3 Sectional view along line AA.

[0124] In another embodiment of the present application, a sealing member 140 is provided between the end of the locking sleeve 110 close to the locking portion 132 and the rod portion 131 along the axial direction of the rod portion 131 .

[0125] The seal 140 may refer to a component used to prevent fluid or solid particles from leaking from adjacent joint surfaces and to prevent foreign matter such as dust and moisture from invading the interior of the device. The seal 140 may be, but is not limited to, an O-ring, a V-ring, an oil seal, a gasket, a packing, or a lip seal.

[0126] The sealing member 140 may be connected between the end of the locking sleeve 110 facing the locking portion 132 and the rod portion 131; wherein the sealing member 140 may be located between the outer circumferential surface of the rod portion 131 and the hole wall of the receiving hole 111; the sealing member 140 may also be sleeved on the outside of the rod portion 131, the outer ring of the sealing member 140 is fixed to the end of the locking sleeve 110 close to the locking portion 132, and the inner ring of the sealing member 140 abuts against the outer circumferential surface of the rod portion 131 to achieve sealing.

[0127] By adopting the technical solution of this embodiment, the seal 140 can achieve sealing between the end of the lock sleeve 110 facing the locking portion 132 and the rod portion 131, further improving the sealing performance of the connecting lock 100 and improving the reliability and service life of the connecting lock 100.

[0128] In another embodiment of the present application, the sealing member 140 includes a sealing ring 141 , the rod portion 131 is inserted into the sealing ring 141 , and the sealing ring 141 is clamped between the outer circumferential surface of the rod portion 131 and the hole wall of the receiving hole 111 .

[0129] The sealing ring 141 is an annular component used for sealing, and the sealing ring 141 is usually made of an elastic material, such as silicone, rubber, etc.

[0130] The sealing ring 141 is located in the receiving hole 111, and the sealing ring 141 is sleeved on the outside of the rod 131, and the sealing ring 141 is clamped between the outer peripheral surface of the rod 131 and the hole wall of the receiving hole 111, that is, the gap between the outer peripheral surface of the rod 131 and the hole wall of the receiving hole 111 is filled with the sealing ring 141. The sealing ring 141 can block the lubricating oil in the connecting lock 100 from volatilizing from the outer peripheral surface of the rod 131 and the hole wall of the receiving hole 111, and can also reduce the external water vapor, impurities and other substances from entering the interior of the connecting lock 100 from the outer peripheral surface of the rod 131 and the hole wall of the receiving hole 111, thereby reducing the risk of wear and corrosion inside the connecting lock 100, which is beneficial to improving the reliability and service life of the connecting lock 100.

[0131] By adopting the technical solution of this embodiment and using the sealing ring 141 to achieve sealing, the sealing performance of the connecting lock 100 can be improved; in addition, the sealing structure is simple and the processing and manufacturing are simple, which is conducive to reducing the cost of the connecting lock 100.

[0133] In another embodiment of the present application, Figure 4 and Figure 5 As shown, the rotating member 120 is provided with a threaded hole 1201 , and the threaded hole 1201 is used for threaded connection with the rod portion 131 .

[0134] The threaded hole 1201 may refer to a hole structure provided with an internal thread, and the rod portion 131 may be provided with an external thread. The threaded connection between the internal and external threads is achieved to realize a threaded connection between the rod portion 131 and the rotating member 120 .

[0135] By adopting the technical solution of this embodiment, the rod 131 and the rotating member 120 are connected by means of threads, which is simple in connection and is also beneficial to improving the production efficiency of the connecting lock 100.

[0136] Generally, after the locking portion 132 passes through the locking hole 1401, there is a certain distance between the locking portion 132 and the second fixing portion 1400 to facilitate the connection between the first fixing portion 13 and the second fixing portion 1400; and in the subsequent connection operation, it is necessary to drive the locking portion 132 to move toward the second fixing portion 1400 until the locking portion 132 abuts against the second fixing portion 1400, thereby achieving the locking and fixation of the first fixing portion 13 and the second fixing portion 1400.

[0137] In another embodiment of the present application, Figure 8 As shown, the guide groove 1311 includes a spiral section 13111 , and the spiral section 13111 extends spirally around the axis of the rod portion 131 .

[0138] It can be understood that the spiral segment 13111 spirally extends around the axis of the rod portion 131 and along the length direction of the rod portion 131 .

[0139] By adopting the technical solution of this embodiment, on the one hand, the setting of the spiral segment 13111 can guide the locking portion 132 to rotate to a preset angle, so that the locking portion 132 and the locking hole 1401 are staggered, thereby realizing the fixed connection between the first fixing portion 13 and the second fixing portion 1400; on the other hand, during the rotation of the rotating member 120, under the guidance of the guide protrusion 112 and the spiral segment 13111, the locking portion 132 will automatically move toward the second fixing portion 1400, thereby making the locking and fixing connection operation of the first fixing portion 13 and the second fixing portion 1400 simpler and more convenient.

[0140] In another embodiment of the present application, Figure 8 As shown, the guide groove 1311 also includes a first straight segment 13112 extending along the axial direction of the rod portion 131; along the axial direction of the rod portion 131, one end of the spiral segment 13111 away from the locking portion 132 is connected to one end of the first straight segment 13112, and the spiral segment 13111 is located between the first straight segment 13112 and the locking portion 132.

[0141] The first straight line segment 13112 can be a segment extending in a straight line in the guiding groove 1311, and the segment is located on the side of the spiral segment 13111 away from the locking portion 132, that is, the spiral segment 13111 is located between the first straight line segment 13112 and the locking portion 132, the first straight line segment 13112 is parallel to the axis of the rod portion 131, and the first straight line segment 13112 is connected to one end of the spiral segment 13111 away from the locking portion 132.

[0142] By adopting the technical solution of this embodiment, the guide protrusion 112 moves in the first straight segment 13112, which can limit the rotation of the locking portion 132, so that the locking portion 132 can smoothly pass through the locking hole 1401 at a preset angle.

[0143] In addition, based on the threaded connection between the rod 131 and the rotating member 120, the guide protrusion 112 can limit the rotation of the rod 131 within the first straight segment 13112, so that the rotating member 120 and the rod 131 can be stably screwed together, so as to facilitate the subsequent rotation of the rotating member 120 to drive the locking portion 132 to rotate.

[0144] In another embodiment of the present application, Figure 8 As shown, along the axial direction of the rod portion 131 , a notch 131121 is formed at the end of the first straight segment 13112 away from the spiral segment 13111 , and the notch 131121 is used for the guide protrusion 112 to pass through so as to enter the first straight segment 13112 .

[0145] The notch 131121 may refer to an opening of the first straight segment 13112 away from the spiral segment 13111 .

[0146] By adopting the technical solution of this embodiment, when the rod 131 is inserted into the receiving hole 111, the guide protrusion 112 can smoothly enter the guide groove 1311 through the notch 131121, making the assembly operation of the locking member 130 and the locking sleeve 110 more convenient and quick.

[0147] In another embodiment of the present application, Figure 8 As shown, along the axial direction of the rod portion 131 , the first straight segment 13112 penetrates the end surface of the rod portion 131 away from the locking portion 132 to form the notch 131121 .

[0148] The first straight segment 13112 extends away from the spiral segment 13111 until it passes through the end surface away from the locking portion 132, that is, the opening formed by the first straight segment 13112 at the end surface of the rod 131 away from the locking portion 132 is a notch 131121. As an example, the first straight segment 13112 can pass through the external thread area of ​​the rod 131.

[0149] The first straight line segment 13112 directly penetrates the end surface of the rod portion 131 away from the locking portion 132 to form a notch 131121 . The structure is simple and the processing and manufacturing are simple, which is conducive to reducing the manufacturing cost.

[0150] In some embodiments, along the axial direction of the rod 131, the outer diameter of the end of the rod 131 away from the locking portion 132 is smaller than the outer diameter of the rod 131 at the first straight section 13112, so that the guide protrusion 112 can use the avoidance space brought by the outer diameter difference to smoothly enter the guide groove 1311. Of course, in other embodiments, the rod 131 can also be other structures. In another embodiment of the present application, combined with Figure 8 As shown, the guide groove 1311 also includes a second straight segment 13113 extending along the axial direction of the rod portion 131. Along the axial direction of the rod portion 131, one end of the spiral segment 13111 close to the locking portion 132 is connected to one end of the second straight segment 13113, and the second straight segment 13113 is located between the spiral segment 13111 and the locking portion 132.

[0151] The second straight line segment 13113 may refer to another segment extending in a straight line in the guide groove 1311, and the segment is located on the side of the spiral segment 13111 close to the locking portion 132, the second straight line segment 13113 is parallel to the axis of the rod portion 131, and the second straight line segment 13113 is connected to one end of the spiral segment 13111 close to the locking portion 132; that is, along the axial direction of the rod portion 131, the first straight line segment 13112 and the second straight line segment 13113 are respectively connected to the two ends of the spiral segment 13111 and are respectively located on opposite sides of the spiral segment 13111 along the axial direction.

[0152] By adopting the technical solution of this embodiment, after the locking portion 132 is offset from the locking hole 1401, the guide protrusion 112 can enter the second straight segment 13113, thereby limiting the rotation of the locking portion 132, so that the locking portion 132 and the locking hole 1401 can be stably offset, reducing the risk of the locking portion 132 escaping from the locking hole 1401; the guide protrusion 112 can also move along the second straight segment 13113, so that the locking portion 132 is close to the second fixing portion 1400, thereby locking and fixing the first fixing portion 13 and the second fixing portion 1400.

[0153] In addition, based on the threaded connection between the rod portion 131 and the rotating member 120, after the locking portion 132 is offset from the locking hole 1401, the rotating member 120 can continue to be rotated, and the guide protrusion 112 enters the second straight line segment 13113, which can limit the rotation of the rod portion 131. At the same time, the locking portion 132 will also move toward the second fixed portion 1400 until it abuts against the second fixed portion 1400, thereby stably locking and fixing the first fixed portion 13 and the second fixed portion 1400.

[0154] In one embodiment, the guide groove 1311 includes a first straight segment 13112, a spiral segment 13111 and a second straight segment 13113 which are connected to each other, and the rod portion 131 is screwed into the threaded hole 1201 of the rotating member 120. The first fixed portion 13 and the second fixed portion 1400 can be locked and unlocked by rotating the rotating member 120, and the use of the connecting lock 100 is more convenient.

[0155] In another embodiment of the present application, Figure 8 As shown, the locking portion 132 is a long strip structure, and at least one end of the long strip structure protrudes out of the outer peripheral side of the rod portion 131 .

The structure of such a design is ingenious and has better practicality.

[0190] In one embodiment, the first plane 12211 and the second plane 16221 are arranged in a one-to-one correspondence, and the number of the first planes 12211 can be multiple, so that the multiple first planes 12211 and the multiple second planes 16221 are arranged one by one relative to each other, so that the relative rotation of the movable part 162 and the rotating part 122 is more difficult, and the anti-rotation effect of the rotating part 122 is better; as an example, the first through hole 1621 is a polygonal hole, and the rotating part 122 is a prism matched with the polygonal hole; for example: the first through hole 1621 is a hexagonal hole, and the rotating part 122 is a hexagonal prism. At this time, the hexagonal sleeve can be used to be sleeved on the outside of the rotating part 122 to realize the rotation of the rotating part 122, and the use of the connecting lock 100 is simpler and more convenient.

Of course, in other embodiments, the first locking structure 1623 and the second locking structure 1612 can also be other structures that can lock the movable member 162 and the fixed member 161.

[0193] By adopting the technical solution of this embodiment, the first locking structure 1623 and the second locking structure 1612 cooperate with each other to achieve locking and fixation of the movable member 162 and the fixed member 161, which has a simple structure and is easy to process and manufacture.

[0195] The first locking structure 1623 adopts the structural form of a locking protrusion 16231, and the second locking structure 1612 adopts the structural form of a locking groove 16121. The locking protrusion 16231 is inserted into the locking groove 16121 to achieve relative locking and fixation of the movable part 162 and the fixed part 161, thereby preventing the rotating part 122 from rotating; the locking protrusion 16231 is moved out of the locking groove 16121 to achieve separation of the movable part 162 and the fixed part 161, so that the rotating part 122 can rotate.

[0208] By adopting the technical solution of this embodiment, the fixed ring 164 is located between the elastic member 163 and the movable member 162. The fixed ring 164 can separate the elastic member 163 and the movable member 162, so that the elastic member 163 does not directly contact the movable member 162, thereby reducing the wear between the elastic member 163 and the movable member 162 and improving the reliability of the connecting lock 100. In addition, the annular groove 1641 can also play a role in radial positioning of the elastic member 163, so that the compression of the elastic member 163 and the pushing of the movable member 162 to reset are smooth, and the anti-rotation mechanism 160 has good reliability.
