[0058] As Figures 1-26 As shown in the locking mechanism 100 according to an embodiment of the present application, comprising: a locking block assembly 1 and a mounting guide rail 3.

[0060] The lock block assembly 1 is provided with a mounting hole portion 11 for mounting the blocking member 2, that is, the mounting hole portion 11 is adapted in shape and size to the shape and size of the blocking member 2, so that the blocking member 2 can be mounted on the lock block assembly 1 through the mounting hole portion 11 to achieve the installation and fixation of the blocking member 2, which is used to block objects and the like to limit the movement of the objects.

[0061] Further, the lock block assembly 1 is slidably mounted on the mounting rail 3, and the lock block assembly 1 is adapted to be selectively locked relative to the mounting rail 3.

[0062] That is, the lock block assembly 1 can slide along the length direction of the mounting rail 3 to achieve flexible adjustment of the position of the lock block assembly 1 on the mounting rail 3, and the lock block assembly 1 can be selectively locked relative to the mounting rail 3, that is, when the lock block assembly 1 is in an unlocked state, it can slide along the mounting rail 3 to adjust its position on the sliding rail, and when adjusted to a suitable position, the lock block assembly 1 can be locked relative to the mounting rail 3, at this time, the lock block assembly 1 is fixed on the mounting rail 3 and cannot slide freely any more, so that the blocking member 2 cannot move either, thereby achieving flexible adjustment and fixation of the position of the blocking member 2, which can be applied to various occasions requiring adjustment and fixation of the position, and has a wide range of applications, and the movement and locking of the lock block assembly 1 can be achieved without using a driving motor or a pneumatic cylinder, so the structure is simple and the cost is low.

[0063] According to the locking mechanism 100 of the embodiment of the utility model, the mounting hole portion 11 is arranged to mount the blocking member 2 on the lock block assembly 1, the lock block assembly 1 is slidably mounted on the mounting rail 3, and the lock block assembly 1 is adapted to be selectively locked relative to the mounting rail 3, thereby achieving flexible adjustment and fixation of the position of the blocking member 2, and the structure is simple, the occupied space is small, and the cost is low, and the utility model has a wide range of applications.

[0064] In some embodiments, as shown in Figure 4 , Figure 6 , Figure 15 and Figure 16 , the lock block assembly 1 comprises a housing 12, a locking structure 13 and a pushing member 14, the locking structure 13 is movably mounted on the housing 12, that is, the locking structure 13 is movable relative to the housing 12 to facilitate unlocking or locking relative to the mounting rail 3, the locking structure 13 is in sliding fit with the mounting rail 3, that is, the locking structure 13 and the mounting rail 3 can slide relative to each other, and the locking structure 13 can slide along the length direction of the mounting rail 3 in a flexible manner in an unlocked state.

[0065] Further, the pushing member 14 is used to push the locking structure 13 to move relative to the housing 12 to selectively lock with the mounting rail 3.

[0066] That is, the user can manually push the pusher 14 to move so that the pusher 14 can push the locking structure 13 to move relative to the housing 12, thereby achieving the unlocking or locking of the locking structure 13 and the mounting rail 3, which is simple and convenient to operate, does not need to drive the motor to drive, reduces the occupied space of the driving motor, and makes the locking mechanism 100 more compact and simple in structure, which is convenient to arrange in the device or equipment.

[0067] In some embodiments, the mounting hole portion 11 is provided on the housing 12, and the mounting hole portion 11 is configured to be open on the side of the housing 12 away from the mounting rail 3.

[0068] Specifically, as shown in Figure 2 , Figure 6 , Figure 16 and Figure 26 , the housing 12 is provided with a mounting hole portion 11, as shown in Figure 26 , the mounting hole portion 11 is open on the side of the housing 12 away from the mounting rail 3, i.e. the upper side shown in Figure 26 , so that the blocking piece 2 can be inserted into the mounting hole portion 11 from above to be mounted in the housing 12, avoiding interference with the mounting rail 3.

[0069] In some embodiments, the housing 12 is provided with a mounting lock tongue 15, which is used to limit and lock the blocking piece 2, i.e. the blocking piece 2 is accurately fixed in the housing 12 and cannot move in the housing 12, thereby achieving the fixed mounting of the blocking piece 2 on the lock block assembly 1, preventing the blocking piece 2 from moving relative to the lock block assembly 1 and affecting the fixing effect of the blocking piece 2.

[0070] Specifically, as shown in Figure 26 , the housing 12 is hollow to form the mounting hole portion 11 open upward, and the lower end of the blocking piece 2 can be provided with a limiting groove 21, when the lower end of the blocking piece 2 is inserted into the mounting hole portion 11, the mounting lock tongue 15 in the housing 12 can be inserted into the limiting groove 21 to limit and lock the blocking piece 2, limiting the blocking piece 2 from moving up and down, deviating and rotating circumferentially, thereby improving the installation accuracy and stability of the blocking piece 2, and the blocking piece 2 can better slide along the mounting rail 3 with the lock block assembly 1 or be fixed and locked on the rail sliding.

[0071] In some embodiments, the housing 12 is further provided with an elastic member 16, which has a certain elastic extension force. The elastic member 16 is elastically pressed between the installation lock tongue 15 and the housing 12, and is adapted to apply an elastic force to the installation lock tongue 15 for locking the blocking member 2. That is, the elastic member 16 can apply an elastic force to the installation lock tongue 15, so that the installation lock tongue 15 can lock and fix the blocking member 2, preventing the blocking member 2 from moving. When the blocking member 2 needs to be unlocked, the elastic extension force of the elastic member 16 can make the installation lock tongue 15 move away from the blocking member 2 to release the locking of the blocking member 2. At this time, the blocking member 2 can move flexibly, and its lower end can extend out of the mounting hole portion 11 to move away from the housing 12, thereby achieving the relative disassembly between the lock block assembly 1 and the blocking member 2.

[0072] Specifically, as shown in Figure 26 , the housing 12 is provided with an elastic member 16. When the blocking member 2 needs to be locked, one side of the elastic member 16 is tightly and elastically pressed against the inner wall of the housing 12, and the other side is tightly and elastically pressed against the installation lock tongue 15, so as to apply an elastic force to the installation lock tongue 15 to make the installation lock tongue 15 tightly clamped into the limiting groove 21, thereby achieving the limiting and locking of the installation lock tongue 15 to the blocking member 2.

[0073] In some embodiments, the pushing member 14 and the locking structure 13 have at least two sets of cooperation points. That is, the pushing member 14 and the locking structure 13 can be provided with two, three or more sets of cooperation points. The cooperation points are used to achieve the cooperation and connection between the pushing member 14 and the locking structure 13. By providing multiple sets of cooperation points, the pushing member 14 can more stably and easily push the locking structure 13 to move relative to the housing 12. The at least two sets of cooperation points are spaced apart and distributed on both sides of the mounting hole portion 11. In this way, the cooperation points can avoid interfering with the mounting hole portion 11, thereby affecting the movement of the pushing member 14 and the locking structure 13.

[0074] In some embodiments, as shown in Figure 6 and Figure 16 , the housing 12 includes an upper housing 121 and a lower housing 122. The upper housing 121 and the lower housing 122 are detachably connected. That is, the upper housing 121 and the lower housing 122 can be connected by detachable connection modes such as buckle connection, threaded connection, clamping hook and clamping hole, clamping convex and clamping hole, etc. Alternatively, the upper housing 121 and the lower housing 122 can be connected by press riveting connection. Only when the upper housing 121 and the lower housing 122 are assembled and meet the torque requirements for locking and unlocking, the connection can be achieved. In this way, the upper and lower housings 122 can be conveniently installed and disassembled. When the structure components in the housing 12 are damaged, the upper housing 121 is damaged, or the lower housing 122 is damaged and needs to be replaced and repaired, the upper and lower housings 122 can be easily and conveniently disassembled for repair and replacement, thereby reducing the maintenance cost. Furthermore, the elastic member 16, the installation lock tongue 15 and other structure components can be conveniently installed in the housing 12, which is flexible and convenient.

[0075] Further, the locking structure 13 and the pushing member 14 are movably mounted on the lower shell 122, the mounting hole portion 11 includes an insertion hole 1211 provided on the upper shell 121 and a locking hole 1221 provided on the lower shell 122, the blocking member 2 is adapted to be inserted from the insertion hole 1211 and locked in the locking hole 1221.

[0076] That is, the locking structure 13 and the pushing member 14 are movable relative to the lower shell 122, so as to realize the locking of the locking block assembly 1 relative to the mounting rail 3 or the unlocking relative to the mounting rail 3. Figure 26 As shown, the mounting hole portion 11 includes an insertion hole 1211 provided on the upper shell 121 and a locking hole 1221 provided on the lower shell 122, the insertion hole 1211 is mainly used for smoothly inserting the blocking member 2 into the shell 12, the blocking member 2 can be locked in the locking hole 1221, the shapes and sizes of the insertion hole 1211 and the locking hole 1221 are matched and the positions are opposite to each other to communicate, so as to facilitate the insertion of the blocking member 2 from the insertion hole 1211 and the extension into the locking hole 1221, Figure 26 As shown in the insertion hole 1211 and the locking hole 1221, the shapes of the insertion hole 1211 and the locking hole 1221 are cylindrical and matched with the shape of the blocking member 2, and can also be constructed as other shapes, such as rectangular, conical, irregular, etc. Among them, the depth of the locking hole 1221 is deeper, so as to facilitate the deeper insertion of the blocking member 2 into the lower shell 122, realize the locking and fixing, and prevent the blocking member 2 from shaking and tilting during movement.

[0077] In the actual installation process, when the blocking member 2 is installed, the blocking member 2 can be inserted into the insertion hole 1211 first, and then extended into the locking hole 1221 to realize the locking and fixing in the locking hole 1221. In the actual design, as shown, Figure 26 The locking pin can be installed at the lower end of the blocking member 2, inserted from the insertion hole 1211 and locked in the locking hole 1221, which improves the reliability of the locking of the blocking member 2.

[0078] In some embodiments, as shown in Figure 4 and Figure 15 The locking structure 13 includes a pushing fitting member 131, a sliding member 132 and a clamping member 133, the sliding member 132 is connected between the pushing fitting member 131 and the clamping member 133, that is, one end of the sliding member 132 is connected with the pushing fitting member 131, and the other end of the sliding member 132 is connected with the clamping member 133, so as to realize the movement transmission from the pushing fitting member 131 to the clamping member 133.

[0079] The sliding member 132 is slidingly installed in the housing 12, and the clamping member 133 is slidingly matched with the installation guide rail 3, that is, the sliding member 132 can slide in the housing 12 to facilitate movement in the locking and unlocking process, and the clamping member 133 can slide along the installation guide rail 3 to achieve adjustment of the arbitrary position of the lock block assembly 1 and the blocking member 2 on the installation guide rail 3.

[0080] Further, the pushing member 14 is abuttingly matched with the pushing matching member 131 to sequentially drive the sliding member 132 and the clamping member 133 to move relative to the housing 12, and at least part of the installation guide rail 3 is locked between the clamping member 133 and the housing 12.

[0081] That is, when the user applies a force to the pushing member 14 to drive the pushing member 14 to move, because the pushing member 14 is abuttingly matched with the pushing matching member 131, the pushing member 14 can drive the pushing matching member 131 to move, and then the pushing matching member 131 can drive the sliding member 132 to slide in a direction in the housing 12, at the same time, the sliding member 132 can drive the clamping member 133 to move relative to the housing 12 when the sliding member 132 slides, so that the clamping member 133 gradually contacts the installation guide rail 3 when the clamping member 133 moves, and finally at least part of the installation guide rail 3 is locked between the clamping member 133 and the housing 12, thereby realizing the locking between the installation guide rail 3 and the lock block assembly 1, that is, the lock block assembly 1 and the blocking member 2 are locked and fixed on the installation guide rail 3 together, and cannot move along the installation guide rail 3, and the locking at an arbitrary position on the installation guide rail 3 is achieved.

[0082] Specifically, as shown in Figure 2 , Figure 4 and Figure 15 , the pushing member 14 is abuttingly matched with the pushing matching member 131, and the pushing matching member 131 is abuttingly matched with the sliding member 132, and the sliding member 132 is abuttingly matched with the clamping member 133. Figure 2As shown in the vertical direction, the mounting rail 3 is formed with a sliding guide groove 31, the upper end of the sliding guide groove 31 is provided with a locking flange 32 and the middle part is open upward, the clamping piece 133 is clamped into the sliding guide groove 31 through the open part of the middle part, so that the locking flange 32 is pressed between the lower end face of the lower shell 122 and the upper end face of the clamping piece 133, so that when the pusher 14 moves relative to the shell 12, the pusher 14 can drive the push-fit piece 131 to move, and then the push-fit piece 131 drives the sliding piece 132 to slide up and down in the shell 12, and at the same time, the sliding piece 132 can drive the clamping piece 133 to move up and down in the sliding guide groove 31 relative to the shell 12 to approach or away from the lower end face of the shell 12, and when the clamping piece 133 moves upward, it gradually approaches the locking flange 32 of the mounting rail 3 and gradually tightly contacts the inner wall surface of the locking flange 32, so that the locking flange 32 is tightly pressed between the clamping piece 133 and the lower shell 122, realizing the locking between the mounting rail 3 and the lock block assembly 1, or when the clamping piece 133 moves downward, it gradually moves away from the locking flange 32 of the mounting rail 3 and is spaced apart from the inner wall surface of the locking flange 32 by a certain distance, thereby realizing the unlocking between the mounting rail 3 and the lock block assembly 1, so that the clamping piece 133 can freely slide in the sliding guide groove 31, that is, the lock block assembly 1 can freely slide along the mounting rail 3.

[0083] In some embodiments, as shown in Figure 3 and Figure 4 , the push-fit piece 131 has a cam groove 1311, and the pusher 14 is provided with a cam portion 141, the cam groove 1311 and the cam portion 141 are matched in shape and size, so that the cam portion 141 can be located in the cam groove 1311 and can move in the cam groove 1311.

[0084] In some embodiments, the pusher 14 is adapted to push the inner wall of the cam groove 1311 by the cam portion 141 to drive the push-fit piece 131 to move.

[0085] That is, the cam portion 141 is in pressing contact with the inner wall of the cam groove 1311, so that when the pusher 14 moves together with the cam portion 141, the cam portion 141 can push and slide along the inner wall of the cam groove 1311 to drive the push-fit piece 131 to move, realizing the transmission of movement from the pusher 14 to the push-fit piece 131.

[0086] In some embodiments, as shown in Figure 9 and Figure 10 , Figure 13 and Figure 14As shown, the cam groove 1311 is formed with a cam matching surface 1311a, which is the region where the cam portion 141 interacts with, and the cam matching surface 1311a has a matching vertex 1311b and a lift point 1311c located at the side of the matching vertex 1311b. The matching vertex 1311b is the highest point where the cam portion 141 presses against the cam matching surface 1311a during movement, and is also the highest point of the movement of the cam portion 141. The lift point 1311c is the starting point or the end point of the movement of the cam portion 141, as shown in the left and right directions in the figure. The lift point 1311c is located at the left side of the matching vertex 1311b. When the cam portion 141 moves gradually from the left lift point 1311c to the matching vertex 1311b, the cam portion 141 moves to the highest point, pushing the matching piece 131 to rise to the highest position.

[0087] Further, the cam portion 141 is arranged to gradually lock the locking structure 13 relative to the mounting rail 3 during movement from the lift point 1311c to the matching vertex 1311b. That is, when the cam portion 141 moves to the matching vertex 1311b, the locking structure 13 is locked relative to the mounting rail 3.

[0088] Specifically, as shown in Figure 9 and Figure 10 、 Figure 13 and Figure 14 , when the cam portion 141 rises, i.e., moves to the right and gradually approaches the matching vertex 1311b, the matching piece 131 is pushed to gradually raise the sliding piece 132 and the clamping piece 133, so that the upper end surface of the clamping piece 133 gradually approaches the locking flange 32 of the mounting rail 3 and gradually tightly contacts the inner wall surface of the locking flange 32. When the cam portion 141 moves to the matching vertex 1311b, the highest point of the cam portion 141 is in pressing contact with the matching vertex 1311b of the cam matching surface 1311a. At this time, the locking flange 32 is tightly pressed against the clamping piece 133 and the lower housing 122, achieving the locking between the mounting rail 3 and the locking block assembly 1, i.e., the locking of the locking structure 13 relative to the mounting rail 3.

[0089] In some embodiments, the pushing piece 14 is rotatably mounted to the housing 12, i.e., the pushing piece 14 can rotate relative to the housing 12, as shown in Figure 4 The pushing piece 14 can be rotatably connected to the lower housing 122 through a mounting shaft 6, and the cam portion 141 is mounted on the mounting shaft 6. In this way, when the pushing piece 14 is pushed, the pushing piece 14 can rotate relative to the housing 12 around the mounting shaft 6.

[0090] Further, as shown in Figure 14As shown, the angle corresponding to the movement of the pushing member 14 and the cam portion 141 from the lift point 1311c to the mating vertex 1311b is A1, which satisfies: 55°≤A1≤60°.

[0091] Specifically, A1 can be set as 55°, 56°, 56.5°, 57°, 58°, 59°, 60° or other angles within the range of 55° to 60°. By setting A1 within this range, the pushing member 14 can rotate to any angle within 55° to 60°, and the cam portion 141 also rotates by the same angle. At this time, the cam portion 141 moves from the lift point 1311c to the mating vertex 1311b, and the locking structure 13 is locked relative to the mounting rail 3.

[0092] In some embodiments, as shown in Figure 15 As shown, the housing 12 is provided with a guide groove 17 for guiding the movement of the rotating shaft 5, so that the rotating shaft 5 can move in the guide groove 17. The pushing member 14 and the pushing fitting member 131 are rotatably connected through the rotating shaft 5, that is, the pushing member 14 and the pushing fitting member 131 can rotate relative to each other through the rotating shaft 5.

[0093] Further, the rotating shaft 5 and the guide groove 17 are in sliding fit, and the pushing member 14 drives the rotating shaft 5 to slide along the guide groove 17 to drive the pushing fitting member 131 to move. That is, the rotating shaft 5 and the guide groove 17 are matched in shape and size, so that the rotating shaft 5 can slide along the guide groove 17. When the pushing member 14 is pushed, the pushing member 14 can drive the rotating shaft 5 to slide along the guide groove 17, so that the rotating shaft 5 drives the pushing fitting member 131 to move when the rotating shaft 5 moves, realizing the transmission of movement from the pushing member 14 to the pushing fitting member 131.

[0094] In some embodiments, as shown in Figure 15 As shown, the rotating shaft 5 includes a main shaft portion 51 and a fitting shaft portion 52 connected in the axial direction. The main shaft portion 51 is fixedly connected to the pushing member 14, so that the pushing member 14 can drive the main shaft portion 51 to move together. The fitting shaft portion 52 is rotatably connected to the pushing fitting member 131, and the main shaft portion 51 is in sliding fit with the guide groove 17. That is, the fitting shaft portion 52 and the pushing fitting member 131 can rotate relative to each other, and the main shaft portion 51 can slide along the guide groove 17.

[0095] Specifically, in practice, as shown in Figure 19 and Figure 20As shown, when the pusher 14 is pushed to move downward, the main shaft part 51 slides downward along the guide groove 17, and at the same time, the main shaft part 51 drives the push matching part 131 to move upward, and the clamping part 133 also moves upward. When the main shaft part 51 moves to the lower end of the guide groove 17, the upper end surface of the clamping part 133 is in close contact with the inner wall surface of the locking flange 32, realizing the locking of the locking structure 13 relative to the mounting rail 3. As shown, Figure 22 and Figure 23 As shown, when the pusher 14 is pushed to move upward, the main shaft part 51 slides upward along the guide groove 17, and at the same time, the main shaft part 51 drives the push matching part 131 to move downward, so that the upper end surface of the clamping part 133 is spaced apart from the inner wall surface of the locking flange 32 by a certain distance, realizing the unlocking of the locking structure 13 relative to the mounting rail 3. When the distance is sufficient, the lock block assembly 1 can slide flexibly along the mounting rail 3.

[0096] In some embodiments, as shown, Figure 15 the outer diameter of the main shaft part 51 is greater than the outer diameter of the matching shaft part 52, so that the main shaft part 51 can be sleeved outside the matching shaft part 52, realizing the connection between the two.

[0097] In some embodiments, the side of the clamping part 133 towards the housing 12 is provided with a buffer 1331, which is suitable for being elastically pressed between the clamping part 133 and the mounting rail 3.

[0098] Specifically, the buffer 1331 has a certain elasticity. When the mounting rail 3 is locked between the clamping part 133 and the housing 12, the buffer 1331 can have a certain buffering and shock-absorbing effect, so as to reduce the friction between the clamping part 133 and the mounting rail 3, prolong the service life, and at the same time, through the elastic force of the buffer 1331, the buffer 1331 can be compressed to be elastically pressed between the clamping part 133 and the mounting rail 3 tightly, so as to ensure the close contact between the clamping part 133 and the mounting rail 3, and improve the reliability and stability of the locking.

[0099] As shown, Figure 26 the upper side of the clamping part 133, i.e. the side towards the housing 12, is provided with a buffer 1331. When the mounting rail 3 is locked between the clamping part 133 and the housing 12, the buffer 1331 is elastically pressed between the clamping part 133 and the mounting rail 3. At this time, the buffer 1331 is compressed by interference, ensuring that the lock body assembly and the mounting rail 3 reach the locked state.

[0100] In actual design, when the locking structure 13 is in the unlocked state, the distance between the buffer 1331 and the mounting rail 3 can be greater than or equal to 2mm, for example, 2mm, 3mm, 4mm, etc., so as to ensure that the lock body assembly can slide freely along the mounting rail 3 in the unlocked state.

[0101] In some embodiments, the pushing member 14 is rotatably mounted to the housing 12, i.e. the pushing member 14 is rotatable relative to the housing 12, as shown in Figure 15 The pushing member 14 is rotatably connected to the lower housing 122 by the mounting shaft 6, so that when the pushing member 14 is pushed, the pushing member 14 can rotate around the mounting shaft 6 relative to the housing 12.

[0102] After the pushing member 14 is locked by the locking structure 13, the pushing member 14 is adapted to continue to rotate from the locked position to the self-locking position, thereby achieving self-locking of the pushing member 14, preventing accidental unlocking, causing the locking block assembly 1 to accidentally slide along the mounting rail 3, thereby improving the locking reliability and stability between the locking structure 13 and the mounting rail 3.

[0103] Further, the corresponding rotation angle of the pushing member 14 from the locked position to the self-locking position is A2, 3°≤A2≤5°.

[0104] Specifically, A2 can be set to 3°, 4°, 5° or other angles, as shown in Figure 9 and Figure 10 When the cam portion 141 moves from the lift point 1311c to the matching vertex 1311b to achieve locking of the locking structure 13 relative to the mounting rail 3, it can continue to rotate right by 3° to 5° to rotate to the self-locking position, at which time the highest point of the cam portion 141 is slightly offset to the right, which can prevent the cam portion 141 from moving to the left.

[0105] As shown in Figure 20 and Figure 24 When the pushing member 14 is rotated by an angle A1, i.e. when the main shaft portion 51 slides along the guide groove 17 to the locked position, the pushing member 14 can continue to rotate downward by an angle A2, so that the main shaft portion 51 can continue to slide downward to the self-locking position, and the pushing member 131 continues to rotate downward by an angle A2.

[0106] The utility model also proposes a vehicle.

[0107] According to the vehicle of the utility model embodiment, the mounting hole portion 11 is arranged to realize the installation of the blocking member 2 on the locking block assembly 1, the locking block assembly 1 is slidably mounted on the mounting rail 3, and the locking block assembly 1 is adapted to be selectively locked relative to the mounting rail 3, realizing flexible adjustment and fixation of the position of the blocking member 2, which is simple in structure, can reduce the space occupation on the vehicle, is beneficial to reducing the weight of the vehicle and reducing the cost.
