The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0067] The locking mechanism 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0068] Reference Figure 1-Figure 3According to the locking mechanism 100 of the first embodiment of the utility model, the locking mechanism 100 is used to connect a first component and a second component. In some embodiments, the first component may be a vehicle body, and the second component may be a chassis; the first component may be a chassis, and the second component may be a vehicle body; or the first component may be a part that needs to be connected, and the second component may be another connection that needs to be connected. The locking mechanism 100 of the utility model can be used to connect and lock any two objects that need to be connected.

[0069] In the embodiment of the first aspect of the utility model, the first component is a vehicle body, and the second component is a chassis. The locking mechanism 100 includes a lock plate 10 and a bolt assembly mechanism 20, the lock plate 10 is suitable for connecting with the vehicle body, the lock plate 10 is formed with a receiving hole 11, the receiving hole 11 passes through the side of the lock plate 10 close to the chassis, the bolt assembly mechanism 20 includes a mounting frame 21 and a rotating mechanism 30, the mounting frame 21 is suitable for connecting with the chassis and the mounting frame 21 is arranged in the receiving hole 11. By setting the lock plate 10 and the bolt assembly mechanism 20, and the lock plate 10 is connected to the vehicle body, and the mounting frame 21 of the bolt assembly mechanism 20 is connected to the chassis, the vehicle body and the chassis can be connected through the lock plate 10 and the bolt assembly mechanism 20, so that the locking mechanism 100 can realize the connection function of the vehicle body and the chassis. In addition, the receiving hole 11 passes through the side of the lock plate 10 close to the chassis, which can provide enough space to facilitate the matching of the mounting frame 21 and the lock plate 10.

[0070] Optionally, a plurality of locking plates 10 may be provided on the vehicle body, and a plurality of locking tongue assembly mechanisms 20, the same number as the locking plates 10 and corresponding one to one, may be provided at corresponding positions of the chassis to ensure the reliability and stability of the connection between the vehicle body and the chassis.

[0071] Optionally, the number of the locking plates 10 and the locking tongue assembly mechanisms 20 corresponding to the locking plates 10 may be determined according to the size of the vehicle.

[0072] Optionally, the locking plate 10 and the vehicle body may be connected via fasteners.

[0073] Optionally, the mounting frame 21 of the bolt assembly mechanism 20 may be connected to the chassis via fasteners.

[0074] Alternatively, the chassis of the vehicle may be a skateboard type chassis.

[0075] The rotating mechanism 30 is arranged on the mounting frame 21 and includes a rotating disk 31 and a plurality of locking members 33. The rotating disk 31 is rotatably arranged on the mounting frame 21. The plurality of locking members 33 are arranged at intervals along the circumference of the rotating disk 31 and are connected to the rotating disk 31. When the rotating disk 31 rotates, the locking members 33 are driven to move along the radial direction of the rotating disk 31, so that the locking members 33 are matched or disengaged from the locking disk 10. The rotating disk 31 rotates, driving the plurality of locking members 33 arranged at intervals along the circumference of the rotating disk 31 and connected to the rotating disk 31 to move, so that the locking members 33 move along the radial direction of the rotating disk 31, and the locking members 33 can be matched or disengaged from the locking disk 10, thereby completing the connection or separation of the vehicle body and the chassis, so that the connection and separation operation time of the vehicle body and the chassis is short. In addition, the number of the locking members 33 is multiple, and the plurality of locking members 33 cooperate with the locking disk 10, which can greatly improve the reliability of the connection between the vehicle body and the chassis, thereby improving the safety of the whole vehicle.

[0076] It should be noted that the “plurality” in the present invention refers to two or more than two.

[0077] For example, refer to Figure 4-Figure 7 The rotating mechanism 30 includes six locking members 33 , and each locking member 33 includes a locking block 34 .

[0078] Among them, when the locking block 34 cooperates with the lock plate 10, the lock tongue assembly mechanism 20 is locked relative to the lock plate 10, and the locking mechanism 100 is in a locked state. At this time, the vehicle body is connected to the chassis, and the lock tongue assembly mechanism 20 is locked relative to the lock plate 10, which can ensure the stability and reliability of the connection between the vehicle body and the chassis; when the locking block 34 is disengaged from the lock plate 10, the lock tongue assembly mechanism 20 can be separated from the accommodating hole 11, and the locking mechanism 100 is in an unlocked state. At this time, the vehicle body is separated from the chassis, and the vehicle body and the chassis can be disassembled. In addition, the locking block 34 cooperates with the lock plate 10 to achieve the locking of the vehicle body and the chassis; the locking block 34 is disengaged from the lock plate 10, and the vehicle body and the chassis can be disassembled, which is relatively simple to operate, and can reduce the difficulty of installing and disassembling the vehicle body and the chassis to a certain extent, and improve the assembly efficiency.

[0079] When the body and the chassis need to be connected, tooling can be used to bring the body and chassis that need to be paired closer together, and the mounting frame 21 set on the chassis is inserted into the accommodating hole 11 of the locking plate 10 set on the body, and then the rotating disk 31 of the lock tongue assembly mechanism 20 is rotated. When the rotating disk 31 rotates, it drives the locking block 34 to move along the radial direction of the rotating disk 31. For example, the rotating disk 31 drives the locking block 34 to move along the radial direction of the rotating disk 31 toward the locking plate 10, so that the locking block 34 cooperates with the locking plate 10, so that the locking mechanism 100 is in a locked state, and the connection between the body and the chassis is completed.

[0080] When the vehicle body and the chassis need to be separated, the rotating disk 31 of the lock tongue assembly mechanism 20 is rotated, and the rotating disk 31 rotates and drives the locking block 34 to move radially along the rotating disk 31. For example, the rotating disk 31 drives the locking block 34 to move radially along the rotating disk 31 toward a direction away from the lock hole disk, so that the locking block 34 is disengaged from the lock plate 10, thereby making the locking mechanism 100 in an unlocked state, and then the mounting frame 21 passed through the accommodating hole 11 of the lock plate 10 can be separated from the accommodating hole 11 by using tooling, thereby completing the separation of the vehicle body and the chassis.

[0081] According to the locking mechanism 100 of the embodiment of the utility model, the quick locking structure includes a locking plate 10 and a locking tongue assembly mechanism 20, and the locking tongue assembly mechanism 20 includes a locking member 33. The locking block 34 of the locking member 33 can achieve the locking and separation of the locking tongue assembly mechanism 20 and the locking hole plate by cooperating with and disengaging from the locking plate 10, thereby achieving the quick locking and separation of the vehicle body and the chassis, so that the connection and separation operation time of the vehicle body and the chassis is relatively short. In addition, the number of locking members 33 is multiple, and the locking blocks 34 of multiple locking members 33 cooperate with the locking plate 10, which can greatly improve the reliability of the connection between the vehicle body and the chassis, thereby improving the safety of the entire vehicle.

[0082] Reference Figure 2-Figure 3 as well as Figure 6-Figure 8 According to some embodiments of the utility model, the mounting frame 21 includes a lock housing 22, the lock housing 22 is inserted into the receiving hole 11, and each locking member 33 includes a connecting rod 37 and a locking block 34, one end of the connecting rod 37 is movably connected to the rotating disk 31, and the locking block 34 is movably connected to the other end of the connecting rod 37. The rotating disk 31 rotates, driving the connecting rod 37 movably connected to the rotating disk 31 to move, and the connecting rod 37 drives the locking block 34 movably connected to the connecting rod 37 to move, thereby realizing the matching or dismatching of the locking block 34 with the locking disk 10, and further realizing the connection or separation of the vehicle body and the chassis.

[0083] The lock housing 22 is formed with a plurality of movable holes 23 arranged at intervals along the circumference of the lock housing 22. The number of the movable holes 23 is the same as the number of the locking members 33 and corresponds one to one. The locking block 34 of each locking member 33 can be movably accommodated in the movable hole 23. The lock housing 22 is provided with a plurality of movable holes 23, and the number of the movable holes 23 is the same as the number of the locking members 33 and corresponds one to one. The movable holes 23 can guide the locking block 34, so that the locking block 34 can move radially along the rotating disk 31 in the movable holes 23, thereby realizing the engagement or disengagement of the locking block 34 with the lock plate 10.

[0084] When the locking mechanism 100 switches from the unlocked state to the locked state, the rotating disk 31 is rotated, the rotating disk 31 drives the connecting rod 37 to move, and the connecting rod 37 drives the locking block 34 to move. Under the guidance of the movable hole 23, the locking block 34 moves radially along the rotating disk 31. For example, the rotating disk 31 drives the locking block 34 to move in the radial direction of the rotating disk 31 toward the locking disk 10, so that the locking block 34 cooperates with the locking disk 10, thereby putting the locking mechanism 100 in the locked state.

[0085] When the locking mechanism 100 switches from the unlocked state to the locked state, the rotating disk 31 is rotated, the rotating disk 31 drives the connecting rod 37 to move, and the connecting rod 37 drives the locking block 34 to move. Under the guidance of the movable hole 23, the locking block 34 moves radially along the rotating disk 31. For example, the rotating disk 31 drives the locking block 34 to move radially along the rotating disk 31 toward a direction away from the lock hole disk, so that the locking block 34 is disengaged from the lock plate 10, thereby putting the locking mechanism 100 in the unlocked state.

[0086] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the rotating disk 31 rotates a set angle to switch the locking mechanism 100 between the locked state and the unlocked state, and the set angle is less than 180°.

[0087] In the related art, the body and chassis of a vehicle are usually connected and locked by fasteners such as bolts. During the connection process of the body and chassis, the bolts need to be tightened a large number of times to ensure that the body and chassis are connected tightly, which makes the connection time of the body and chassis longer. At the same time, during the separation process of the body and chassis, the bolts need to be tightened back a large number of times to make the body and chassis contact and connect, which makes the separation time of the body and chassis also longer.

[0088] In the locking mechanism 100 of the present invention, the rotation angle of the rotating disk 31 is less than 180° and the locking mechanism can be quickly switched between the locked state and the unlocked state, so that the connection and separation operation time between the vehicle body and the chassis is shorter, which can improve the efficiency of assembly and disassembly.

[0089] Reference Figure 4-Figure 7 as well as Figure 19-Figure 23According to some embodiments of the present invention, the locking block 34 includes a locking portion 35 and a connecting portion 36, the locking portion 35 is spherical, and the connecting portion 36 is hinged to the other end of the connecting rod 37. By providing the locking portion 35, and the locking portion 35 is spherical, the contact area between the spherical locking portion 35 and the movable hole 23 is small, so that the friction between the locking block 34 and the movable hole 23 is small, so that the movement of the locking block 34 in the movable hole 23 can be smoother. By providing the connecting portion 36, the connection between the locking block 34 and the connecting rod 37 can be facilitated. In addition, the connecting portion 36 is hingedly connected to the other end of the connecting rod 37. The hinged connection of the connecting portion 36 and the connecting rod 37 can reduce the stress concentration of the locking member 33 during the movement process. At the same time, the connection method is more flexible, which can facilitate the maintenance and replacement of the locking block 34 and the connecting rod 37.

[0090] Reference Figure 2-Figure 3 as well as Figure 14-15 According to some embodiments of the utility model, the inner peripheral wall of the receiving hole 11 forms a limited step surface 12, and when the locking block 34 cooperates with the lock plate 10, the locking block 34 contacts the limited step surface 12. By providing the limited step surface 12 on the inner wall of the receiving hole 11, when the locking block 34 cooperates with the lock plate 10, the locking block 34 contacts the limited step surface 12, and the limited step surface 12 can limit the locking block 34, so that the position of the locking block 34 can be relatively stable, thereby ensuring the stability and reliability of the locking of the bolt assembly mechanism 20 and the lock plate 10.

[0091] Reference Figure 2-Figure 3 as well as Figure 14-15 According to some embodiments of the utility model, the limiting step surface 12 extends obliquely in the radially inward direction of the receiving hole 11 in the direction away from the vehicle body. When the locking block 34 cooperates with the lock plate 10, the limiting step surface 12 extending obliquely in the radially inward direction of the receiving hole 11 in the direction away from the vehicle body can support and limit the locking block 34, so that the locking block 34 can be in close contact with the limiting step surface 12, and a gap between the locking block 34 and the limiting step surface 12 can be avoided, resulting in an unstable connection between the vehicle body and the chassis. At the same time, the limiting step surface 12 extends obliquely in the radially inward direction of the receiving hole 11 in the direction away from the vehicle body, and the structure is relatively simple, which can facilitate the processing and manufacturing of the limiting step surface 12. At the same time, the obliquely extended limiting step surface 12 can also guide the locking block 34, which can prevent the locking block 34 from getting stuck with the lock plate 10 during movement.

[0092] In addition, when the locking block 34 cooperates with the locking plate 10, multiple locking members 33 are arranged at intervals along the circumference of the rotating plate 31, and the locking blocks 34 of the multiple locking members 33 are all in contact with the limiting step surface 12, and the contact is relatively tight, so that the body and the chassis can be locked in multiple directions.

By setting the first positioning surface 13 on the inner peripheral wall of the receiving hole 11 and setting the second positioning surface 24 on the outer peripheral wall of the lock shell 22, the first positioning surface 13 is opposite to and in contact with the second positioning surface 24, which can play a positioning role, can facilitate the matching of the bolt assembly mechanism 20 and the lock plate 10, and further can facilitate the installation of the vehicle body and the chassis. In addition, the first positioning surface 13 contacts the second positioning surface 24, and the locking block 34 contacts the limiting step surface 12, so that the bolt assembly mechanism 20 and the lock plate 10 have a larger contact area, thereby ensuring the stability and reliability of the locking of the bolt assembly mechanism 20 and the lock plate 10.

[0094] Reference Figure 2-Figure 3 as well as Figure 14-15 According to some embodiments of the utility model, the outer peripheral wall of the lock shell 22 is formed with a limiting convex plate 25, and the limiting convex plate 25 is located on the side of the lock plate 10 away from the vehicle body and contacts the lock plate 10 in the up-down direction. By providing the limiting convex plate 25, the limiting convex plate 25 is located on the side of the lock plate 10 away from the vehicle body and contacts the lock plate 10 in the up-down direction. The limiting convex plate 25 can support the lock plate 10, and at the same time, the lock tongue assembly structure can be in close contact with the lock plate 10, so as to ensure the stability and reliability of the lock tongue assembly mechanism 20 and the lock plate 10. In addition, the limiting convex plate 25 contacts the lock plate 10 in the up-down direction, which can play a limiting role and a positioning role, so that the lock tongue assembly mechanism 20 and the lock plate 10 cooperate more accurately.

[0095] Reference Figure 2-Figure 3 as well as Figure 27-Figure 29According to some embodiments of the present invention, the bolt assembly mechanism 20 includes a rotating member 40, at least part of which is disposed in the lock housing 22, which may be part of the rotating member 40 disposed in the lock housing 22, or the entire rotating member 40 is disposed in the lock housing 22, the rotating member 40 is connected to the side of the rotating disk 31 away from the vehicle body, a matching hole 41 is formed on the rotating member 40, a matching shaft 32 is provided on the rotating disk 31, the matching shaft 32 is accommodated in the matching hole 41, the cross-section of the matching shaft 32 and the cross-section of the matching hole 41 are both polygonal, and when the rotating member 40 rotates, the matching shaft 32 can be driven to rotate, so as to drive the rotating disk 31 to rotate. The rotating member 40 rotates, which can drive the matching shaft 32 accommodated in the matching hole 41 to rotate, thereby driving the rotating disk 31 to rotate, and then driving the locking member 33 to move, so as to achieve the matching or dismatching of the locking block 34 with the lock plate 10.

[0096] Reference Figure 2-Figure 3 as well as Figure 27-Figure 29 According to some embodiments of the present invention, the cross-section of the mating shaft 32 and the cross-section of the mating hole 41 are both hexagonal. The cross-section of the mating shaft 32 and the cross-section of the mating hole 41 are both hexagonal. After the mating hole 41 on the rotating member 40 rotates a certain angle, the inner wall of the mating hole 41 can abut against the outer wall of the mating shaft 32 and drive the mating shaft 32 to rotate, thereby realizing the function of the rotating member 40 driving the rotating disk 31 to rotate. In addition, the cross-section of the mating shaft 32 and the cross-section of the mating hole 41 are both hexagonal, which is relatively simple in shape and can facilitate the processing and production of the mating shaft 32 and the mating hole 41.

[0097] Reference Figure 2-Figure 3 as well as Figure 27-Figure 29 According to some embodiments of the utility model, a driving hole 42 is further formed on the rotating member 40. The driving hole 42 is located on the axial side of the matching hole 41 away from the rotating disk 31. The driving hole 42 is used to cooperate with an auxiliary tool, and the auxiliary tool drives the rotating member 40 to rotate. By providing the driving hole 42, the auxiliary tool cooperates with the driving hole 42 and drives the rotating member 40 to rotate. The rotating member 40 drives the rotating disk 31 provided with the matching shaft 32 to rotate through the matching hole 41. The rotating disk 31 drives the locking block 34 to rotate along the radial direction of the rotating disk 31, so as to achieve the matching or dismatching of the locking block 34 and the locking disk 10. The operation process is relatively simple, which can reduce the workload and difficulty of installing and disassembling the vehicle body and the chassis.

[0098] Optionally, a screw rod that matches the size of the driving hole 42 can be used to manually rotate the screw rod to drive the rotating member 40 to rotate. For example, the cross section of the driving hole 42 is hexagonal, and the auxiliary tool is a hexagonal bolt that matches the driving hole 42. The rotating member 40 is driven to rotate by manually rotating the hexagonal screw rod.

[0099] Reference Figure 2-Figure 7According to some embodiments of the utility model, the rotating member 40 has a first state and a second state, and the rotating member 40 can move between the first position and the second position along the axial direction of the rotating member 40 to switch between the second state and the first state. The mounting frame 21 includes a limit bracket 26, and the limit bracket 26 is arranged in the lock shell 22 and connected to the lock shell 22. A matching shaft 32 is arranged on the rotating disk 31, and a matching hole 41 is arranged on the rotating member 40. The matching shaft 32 is accommodated in the matching hole 41, so that the rotating member 40 can move along the axial direction of the rotating member 40. In addition, the rotating member 40 moves between the first position and the second position along the axial direction of the rotating member 40, so that the rotating member 40 can switch between the second state and the first state. The switching process is relatively simple and the operation is relatively convenient. The limit bracket 26 is arranged in the lock shell 22 and connected to the lock shell 22. The structure is relatively compact and can make full use of the space in the lock shell 22. At the same time, the limit bracket 26 is connected to the lock shell 22, which can improve the overall structural strength of the lock tongue assembly mechanism 20.

[0100] Optionally, the limiting bracket 26 and the lock housing 22 may be connected by a fastener.

[0101] The limiting bracket 26 is located at the outer peripheral side of the rotating member 40, and a limiting protrusion 43 is formed on the outer peripheral wall of the rotating member 40, and a limiting groove 27 is formed on the side of the limiting bracket 26 facing the rotating member 40. When the rotating member 40 is located at the first position, the rotating member 40 is in the first state, and the limiting protrusion 43 is accommodated in the limiting groove 27. The limiting protrusion 43 cooperates with the limiting groove 27 to play a role in limiting and preventing loosening, and can prevent the position of the rotating member 40 from being unstable, resulting in the position of the rotating disk 31 and the locking member 33 being unstable, and then causing the locking state of the locking mechanism 100 to be unstable.

[0102] When the rotating member 40 is located at the second position, the rotating member 40 is in the second state, the limiting protrusion 43 is disengaged from the limiting groove 27, and the rotating member 40 can rotate. After the limiting protrusion 43 is disengaged from the limiting groove 27, the rotating member 40 can drive the rotating disk 31 to rotate, and when the rotating disk 31 rotates, the locking block 34 is driven to move along the radial direction of the rotating disk 31. When the locking block 34 moves to the corresponding position, the rotating member 40 can move along the axial direction of the rotating member 40 to the first position again and be in the first state again, so that the locking block 34 is engaged with or disengaged from the locking plate 10.

[0103] Reference Figure 2-Figure 7 as well as Figure 24-Figure 29According to some embodiments of the present invention, the movable distance of the rotating member 40 along the axial direction of the rotating member 40 ranges from 6 to 10 mm, for example, the movable distance of the rotating member 40 along the axial direction of the rotating member 40 is 8 mm. If the movable distance of the rotating member 40 along the axial direction of the rotating member 40 is greater than 10 mm, the movable distance of the rotating member 40 along the axial direction will be greater, resulting in a larger overall size of the bolt assembly mechanism 20 and a relatively high cost; if the movable distance of the rotating member 40 along the axial direction of the rotating member 40 is less than 6 mm, the movable distance of the rotating member 40 along the axial direction will be smaller, resulting in smaller sizes of the limiting groove 27 and the limiting protrusion 43, and the limiting and anti-loosening effect of the limiting protrusion 43 and the limiting groove 27 cannot be guaranteed.

[0104] By setting the axial movable distance range of the rotating member 40 to 6 to 10 mm, the overall size of the lock tongue assembly 20 can be made smaller and the cost lower. At the same time, it can ensure that the limiting groove 27 and the limiting protrusion 43 can play a better limiting role.

[0105] Reference Figure 2-Figure 7 as well as Figure 24-Figure 29 According to some embodiments of the utility model, a avoidance opening 28 extending along the circumferential direction of the rotating member 40 is formed on the limiting bracket 26, and the avoidance opening 28 and the limiting groove 27 are arranged along the axial direction of the rotating member 40. When the rotating member 40 is in the second state, the limiting protrusion 43 is located in the avoidance opening 28 and is movable along the circumferential direction of the rotating member 40. When the rotating member 40 is in the second position, the limiting protrusion 43 of the rotating member 40 is disengaged from the limiting groove 27 of the limiting bracket 26, and can enter the avoidance opening 28 and can move along the circumferential direction of the rotating member 40 in the avoidance opening 28. By providing the avoidance opening 28, it is possible to avoid the interference between the limiting protrusion 43 of the rotating member 40 and the limiting bracket 26 during the rotation of the rotating member 40, so that the rotation of the rotating member 40 provided with the limiting protrusion 43 can be smoother.

[0106] Reference Figure 2-Figure 7 as well as Figure 24-Figure 29 According to some embodiments of the utility model, the limiting bracket 26 is formed with two limiting grooves 27 spaced apart along the circumference of the rotating member 40, and the two limiting grooves 27 are respectively a first limiting groove 271 and a second limiting groove 272, and the first limiting groove 271 and the second limiting groove 272 are both located on the same side of the avoidance opening 28. The first limiting groove 271 and the second limiting groove 272 are both located on the same side of the avoidance opening 28, and the first limiting groove 271 and the second limiting groove 272 can cooperate with the same limiting protrusion 43 on the rotating member 40, and the structure is relatively simple, which can facilitate the processing and manufacturing of the rotating member 40 and the limiting groove 27.

[0107] Among them, when the locking block 34 cooperates with the locking plate 10, the limiting protrusion 43 is accommodated in the first limiting groove 271. At this time, the rotating member 40 is in the first state, which can avoid the unstable position of the rotating member 40, resulting in unstable position of the rotating plate 31 and the locking member 33, and further affecting the cooperation between the locking block 34 and the locking plate 10, thereby ensuring the reliability and safety of the connection between the body and the chassis.

[0108] When the locking block 34 is disengaged from the locking plate 10, the limiting protrusion 43 is accommodated in the second limiting groove 272. At this time, the rotating member 40 is in the first state, which can prevent the rotating member 40 from being unstable during the separation of the vehicle body and the chassis, causing the locking block 34 to move and thus affecting the separation operation.

[0109] Reference Figure 2-Figure 7 as well as Figure 24-Figure 29 According to some embodiments of the present invention, the circumferential angle between the first limiting groove 271 and the second limiting groove 272 is in the range of 30 to 50°, for example, the circumferential angle between the first limiting groove 271 and the second limiting groove 272 is 40°. The circumferential angle between the first limiting groove 271 and the second limiting groove 272 refers to the angle of rotation of the rotating member 40 from the position where the limiting protrusion 43 cooperates with the first limiting groove 271 to the position where the limiting protrusion 43 cooperates with the second limiting groove 272.

[0110] If the circumferential angle between the first limiting groove 271 and the second limiting groove 272 is greater than 50°, the circumferential angle between the first limiting groove 271 and the second limiting groove 272 will be too large, making the size of the avoidance opening 28 larger, thereby resulting in a lower structural strength of the limiting bracket 26; if the circumferential angle between the first limiting groove 271 and the second limiting groove 272 is less than 30°, the circumferential angle between the first limiting groove 271 and the second limiting groove 272 will be too small, making the distance between the first limiting groove 271 and the second limiting groove 272 closer, resulting in the sizes of the first limiting groove 271, the second limiting groove 272 and the limiting protrusion 43 being smaller, thereby failing to ensure the limiting effect of the limiting protrusion 43 and the limiting groove 27.

[0111] By setting the circumferential angle range between the first limiting groove 271 and the second limiting groove 272 to 30 to 50°, the size of the avoidance opening 28 can be made more moderate, thereby ensuring the structural strength of the limiting bracket 26. At the same time, the sizes of the first limiting groove 271, the second limiting groove 272 and the limiting protrusion 43 can be made more moderate, thereby ensuring that the limiting protrusion 43 and the first limiting groove 271 and the second limiting groove 272 can play a better limiting role.

[0112] It should be noted that the projection of the rotating member 40 on the reference surface is the first projection, the projection of the first limiting groove 271 on the reference surface is the second projection, the projection of the second limiting groove 272 on the reference surface is the third projection, the line connecting the center of the second projection and the center of the first projection is the first line, the line connecting the center of the third projection and the center of the first projection is the second line, and the angle between the first line and the second line is the circumferential angle between the first limiting groove 271 and the second limiting groove 272. The reference surface is a plane perpendicular to the axis of the rotating member 40.

[0113] Optionally, the outer peripheral wall of the rotating member 40 is formed with a plurality of limiting protrusions 43 spaced apart along the circumference of the rotating member 40, a plurality of avoidance openings 28 having the same number as the limiting protrusions 43 are provided at corresponding positions of the limiting bracket 26, and a plurality of first limiting grooves 271 and second limiting grooves 272 are also provided at corresponding positions of the limiting bracket 26. The number of the first limiting grooves 271 and the second limiting grooves 272 is the same, and the number of the first limiting grooves 271 and the second limiting grooves 272 is the same as the number of the limiting protrusions 43 and the avoidance openings 28.

[0114] For example, refer to Figure 24-Figure 29 The outer wall of the rotating member 40 is formed with three limiting protrusions 43 spaced apart along the circumference of the rotating member 40, the limiting bracket 26 is formed with three avoidance openings 28, and the limiting bracket 26 is respectively formed with three first limiting grooves 271 and three second limiting grooves 272 spaced apart along the circumference of the rotating member 40.

[0115] Reference Figure 2-Figure 3 as well as Fig.30 According to some embodiments of the utility model, the locking mechanism 100 includes an elastic reset member 50, one end of which is connected to the rotating member 40 and the other end of which is connected to the mounting bracket 21. The first position is located on the side of the second position away from the rotating disk 31, and the elastic reset member 50 is used to drive the rotating member 40 to move from the second position to the first position. An elastic reset member 50 is provided between the rotating member 40 and the mounting bracket 21. When the rotating member 40 moves from the first position to the second position, the elastic reset member 50 is in a compressed state under the action of an external force. For example, the rotating member 40 is manually pushed to move the rotating member 40 to the second position. In the process of pushing the rotating member 40, the elastic reset member 50 is in a compressed state. At this time, the rotating member 40 switches from the first state to the second state, and the rotating member 40 can drive the rotating disk 31 to rotate. When the rotating disk 31 rotates, it drives the locking block 34 to move radially along the rotating disk 31. When the locking block 34 moves to the corresponding position, the external force acting on the elastic return member 50 is removed. The elastic return member 50 can drive the rotating member 40 to move to the first position under the action of the elastic force of the elastic return member 50, so that the rotating member 40 is in the first state again.

[0116] By providing the elastic reset member 50 , the elastic reset member 50 can drive the rotating member 40 to move from the second position to the first position through elastic force, so the structure is relatively simple and the operation is relatively convenient.

[0117] Reference Figure 1-Figure 7 The mounting frame 21 includes a limit bracket 26, which is arranged in the lock housing 22 and connected to the lock housing 22. The locking mechanism 100 includes a rotating member 40, a limit protrusion 43 is formed on the outer peripheral wall of the rotating member 40, and a avoidance opening 28 extending along the circumference of the rotating member 40 is formed on the limit bracket 26. Two limit grooves 27 are formed on the limit bracket 26 and are arranged at intervals along the circumference of the rotating member 40. The two limit grooves 27 are respectively a first limit groove 271 and a second limit groove 272. The first limit groove 271 and the second limit groove 272 are both located on the same side of the avoidance opening 28. The locking mechanism 100 also includes an elastic reset member 50, one end of which is connected to the rotating member 40 and the other end of which is connected to the mounting frame 21. Among them, the first position is located on the side of the second position away from the rotating disk 31, and the elastic reset member 50 is used to drive the rotating member 40 to move from the second position to the first position.

[0118] When the vehicle body and the chassis need to be connected, the tooling can be used to bring the vehicle body and the chassis that need to be matched close together, and the mounting frame 21 arranged on the chassis is inserted into the receiving hole 11 of the locking plate 10 arranged on the vehicle body, and then the rotating member 40 is pressed to move the rotating member 40 from the first position to the second position and disengage from the second limiting groove 272. The elastic reset member 50 is in a compressed state under the action of the external force, and the rotating member 40 is in the second state and is located in the avoidance opening 28. Then the rotating member 40 is rotated to rotate a certain angle in the avoidance opening 28. During this process, the rotating disk 31 rotates and drives the locking block 34 to move radially along the rotating disk 31. For example, the rotating disk 31 drives the locking block 34 to move radially along the rotating disk 31 toward the direction close to the locking disk 10, so that the locking block 34 cooperates with the locking disk 10. At this time, stop pressing the rotating member 40. The elastic reset member 50 can drive the rotating member 40 to move to the first position again under the action of the elastic force of the elastic reset member 50 and be accommodated in the first limiting groove 271, so that the locking mechanism 100 is in a locked state, completing the connection between the body and the chassis.

[0119] When the vehicle body and the chassis need to be separated, the rotating member 40 is pressed so that the rotating member 40 moves from the first position to the second position and disengages from the first limiting groove 271. The elastic reset member 50 is in a compressed state under the action of the external force, and the rotating member 40 is in the second state and is located in the avoidance opening 28. Then, the rotating member 40 is rotated so that the rotating member 40 rotates a certain angle in the avoidance opening 28. During this process, the rotating disk 31 rotates and drives the locking block 34 to move along the radial direction of the rotating disk 31. For example, the rotating disk 31 drives the locking block 34 to move along the rotating disk 31 moves in the radial direction away from the lock hole disk so that the locking block 34 is disengaged from the lock plate 10. At this time, stop pressing the rotating member 40, and the elastic return member 50 can drive the rotating member 40 to move to the first position again under the action of the elastic force of the elastic return member 50 and be accommodated in the second limiting groove 272, so that the locking mechanism 100 is in an unlocked state, and then the mounting frame 21 penetrating the accommodating hole 11 of the lock plate 10 can be separated from the accommodating hole 11 by using tooling, thereby completing the separation of the body and the chassis.

The locking block 34 of the locking member 33 can achieve the locking and separation of the locking tongue assembly mechanism 20 and the locking hole plate by cooperating and disengaging with the locking plate 10, thereby realizing the quick locking and separation of the vehicle body and the chassis, so that the connection and separation operation time of the vehicle body and the chassis is short. In addition, the number of locking members 33 is multiple, and the locking blocks 34 of multiple locking members 33 cooperate with the locking plate 10, which can greatly improve the reliability of the connection between the vehicle body and the chassis, thereby improving the safety of the whole vehicle.
