[0052] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0053] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0054] With technological advancements, cover locks have gradually evolved from traditional mechanical locks to keyless electronic locks. In existing electronic lock designs, to prevent problems such as blockages in the transmission components and malfunctions in the electronic control components, a flexible element must be connected in series in the transmission relationship, and a backdoor for unlocking must be provided in the structure.

[0055] In the prior art, under the force of the physical structure, the latch and the latch resist the elastic force of the internal elastic element and achieve locking through reciprocating rotation or translation. This locking state is not completely fixed, that is, when there is a force in the opposite direction to the elastic force of the elastic element, the latch will move in the unlocking direction, resulting in unlocking.

[0056] Secondly, in vehicle-mounted scenarios, the vibrations of a moving vehicle can generate significant acceleration and inertial forces. If the direction of these inertial forces coincides with the direction of the elastic force, it can also cause the cover lock to accidentally unlock. Due to the operational requirements of cover locks, elastic elements are essential to ensure that the cover lock can be engaged without additional control during installation. Therefore, existing cover locks inherently suffer from the problem of accidental unlocking due to vibration.

[0057] like Figure 1 As shown, the lock assembly of this utility model embodiment includes a housing 1, two locking tongues 2, a linkage 3, a first elastic element 4, and a locking pin 5.

[0058] For example, such as Figure 2 As shown, the shell 1 can be a flat rectangular shell. The material of the shell 1 can be plastic, metal, etc. The shell 1 can be arranged vertically as a whole, and the larger surface of the outer surface of the shell 1 can be arranged perpendicular to the front and back direction.

[0059] Both locking tongues 2 are slidably fitted into the housing 1 along a first direction and each has a locked position and an unlocked position, for example, as Figure 1 As shown, the first direction can be the left and right direction, the two locking tongues 2 can be arranged opposite each other in the left and right direction, and both locking tongues 2 can slide relative to the housing 1 in the left and right direction.

[0060] Each latch 2 includes a tongue 21, for example, as Figure 1 As shown, the tongue 21 can be integrally formed on the latch 2, and the tongue 21 as a whole can be a wedge-shaped structure. That is, the height of each tongue 21 can gradually decrease in the direction of the outer side of the housing 1.

[0061] It should be noted that each locking bolt 2 has a locked position and an unlocked position during the sliding process, such as... Figure 1 and Figure 2 As shown, at this time, each latch 2 is in the locked position. At this time, the tongue 21 of each latch 2 extends out of the housing 1, and each tongue 21 is used to lock and limit with the set component, so as to realize the locking and fixing of the set component. The set component can be a cover plate, door body, box plate and other structural parts with buckle and other structures.

[0062] When both latches 2 are switched to the unlocked position, the tongue 21 of each latch 2 will be released from the locking component and retract into the housing 1, so that the locking component can be removed from the lock assembly.

[0063] A linkage 3 is connected between the two latches 2. The linkage 3 is used to drive the other latch 2 to slide in the opposite direction when one latch 2 slides. For example, the linkage 3 can be a gear, etc. The linkage 3 can engage with both latches 2 simultaneously. When one latch 2 slides relative to the housing 1, due to the linkage action of the linkage 3, the other latch 2 will slide synchronously in the opposite direction to the movement direction of the first latch 2.

[0064] In some other embodiments, the linkage 3 can also be a connecting rod, etc. In this case, the middle part of the connecting rod can be rotatably assembled with the housing 1, and both locking tongues 2 can be slidably assembled with the connecting rod. When the connecting rod swings, the connecting rod can push the locking tongue 2, and both locking tongues 2 can slide along the extension direction of the connecting rod.

[0065] Specifically, when the left latch 2 moves to the left, the right latch 2 will move to the right in a synchronized manner. When the left latch 2 moves to the right, the right latch 2 will move to the left in a synchronized manner.

[0066] The first elastic element 4 is disposed between the two locking tongues 2, and the first elastic element 4 is used to drive the two tongues 21 from the unlocked position to the locked position. For example, as Figure 1 As shown, the first elastic element 4 can be a spring. The first elastic element 4 can be clamped between the two locking tongues 2. The left end of the first elastic element 4 can abut against the left locking tongue 2, and the right end of the first elastic element 4 can abut against the right locking tongue 2.

[0067] Under the action of the first elastic element 4, the two locking tongues 2 always have a tendency to move towards the locking position on their own. This ensures the structural stability of the locking state and keeps the two locking tongues 2 in contact with the inner wall of the housing 1, thus preventing foreign objects such as dust and particulate impurities from entering the housing 1 through the through hole from which the tongue 21 protrudes.

[0068] The locking pin 5 is slidably fitted into the housing 1 along the second direction. The locking pin 5 is used to engage with at least one locking tongue 2 when the locking tongue 2 is in the locked position to lock and fix the two locking tongues 2.

[0069] For example, such as Figure 1 As shown, the locking pin 5 can be a cylindrical structure, and the second direction can be vertical. The locking pin 5 can be slidably assembled inside the housing 1 and can reciprocate in the vertical direction. When both locking tongues 2 are switched to the locked position under the action of the first elastic member 4, the locking pin 5 can be driven to move upward, and the locking pin 5 will be inserted into the corresponding insertion hole of the right locking tongue 2, thereby locking the right locking tongue 2. Since the two locking tongues 2 are connected by the linkage member 3, when one locking tongue 2 is locked, the linkage member 3 and the other locking tongue 2 will also be locked, ensuring the stability of the two locking tongues 2 in the locked position.

[0070] In some other embodiments, the locking pin 5 may also engage with both locking tongues 2 simultaneously, or the locking pin 5 may engage with the locking tongue 2 on the left side.

[0071] It should be noted that the retraction of the tongue 21 can be partial, meaning that after retraction, the tongue 21 can still be guided and fitted into the corresponding through hole. The fit between the tongue 21 and the hole wall can prevent foreign objects from entering the housing, thus avoiding the problem that foreign objects can easily enter through the through hole when the tongue 21 is fully retracted.

[0072] The lock assembly of this utility model embodiment is provided with two locking tongues 2. The first elastic element 4 acts between the two locking tongues 2, and the two locking tongues 2 move in opposite directions during use. In this way, when one locking tongue 2 mislocks due to factors such as vibration and inertia, the other locking tongue 2 will still remain locked due to the different directions of movement, thereby ensuring the stability of the locking state.

[0073] Secondly, when the locking tongue 2 is in the locked position, the locking pin 5 can lock the two locking tongues 2, which restricts the movement of the two locking tongues 2 in the left and right directions, further ensuring the stability of the locked state and avoiding mis-locking.

[0074] In addition, when both locks are in the locked position, due to the action of the first elastic element 4, the locking pin 5, etc., the corresponding end faces of the two locking tongues 2 will be tightly fitted with the inner wall of the housing 1, thereby preventing foreign objects from entering the housing 1, and thus preventing foreign objects such as mud and sand from entering and causing the locking tongues 2 of the lock assembly to move and become stuck and unable to unlock.

[0075] In some embodiments, the latch 2 is provided with a dustproof surface 22, the dustproof surfaces 22 of the two latches 2 are arranged opposite to each other, the tongue 21 is provided on the dustproof surface 22, and in the locked position, the dustproof surface 22 of each latch 2 is in contact with the inner wall of the housing 1.

[0076] For example, such as Figure 1 As shown, the dustproof surface 22 of the left latch 2 can be the left wall surface of the latch 2. When the left latch 2 is switched to the locked position, the dustproof surface 22 of the latch 2 can be tightly fitted against the left inner wall of the housing 1. The dustproof surface 22 of the right latch 2 can be the right wall surface of the latch 2. When the right latch 2 is switched to the locked position, the dustproof surface 22 of the latch 2 can be tightly fitted against the right inner wall of the housing 1. This effectively prevents foreign objects such as mud and sand from entering the housing 1.

[0077] In some embodiments, one latch 2 is provided with a guide portion 23, and the other latch 2 is provided with a guide hole 24. The guide portion 23 is guided and fitted into the guide hole 24, and the first elastic member 4 is sleeved on the outer periphery of the guide portion 23 and supported between the two latches 2.

[0078] For example, such as Figure 1 As shown, the guide portion 23 can be in the shape of a round shaft. The guide portion 23 can be fixed to the right latch 2 by means of threaded assembly, and the guide portion 23 as a whole can extend in the left and right direction. The guide hole 24 can be provided on the right side of the left latch 2, and the guide hole 24 can also extend in the left and right direction.

[0079] During assembly, the guide portion 23 can be inserted into the guide hole 24, and the first elastic element 4 can be sleeved on the outer periphery of the guide portion 23, thereby ensuring the structural stability of the assembly of the first elastic element 4. During use, as the two locking tongues 2 move closer or further apart, the guide portion 23 can slide within the guide hole 24, thereby enhancing the guiding nature of the movement of the two locking tongues 2.

[0080] In some embodiments, the linkage 3 is a first gear, which is rotatably assembled in the housing 1. The two locking tongues 2 are a first locking tongue 210 and a second locking tongue 211, respectively. The first locking tongue 210 is provided with a first rack 25, and the second locking tongue 211 is provided with a second rack 26. The first rack 25 and the second rack 26 both extend along a first direction, and the first gear meshes between the first rack 25 and the second rack 26.

[0081] For example, such as Figure 1 As shown, the first gear can be rotatably mounted in the housing 1 via a pivot, and the pivot of the first gear can extend along the front-back direction. The first latch 210 can be the left latch 2, and the second latch 211 can be the right latch 2. The bottom side of the first latch 210 can be provided with a first rack 25, and the second latch 211 can be L-shaped in general. The top side of the lower half of the second latch 211 can be provided with a second rack 26. Both the first rack 25 and the second rack 26 can extend along the left-right direction.

[0082] The aforementioned first gear can simultaneously mesh with the first rack 25 and the second rack 26, thereby realizing the linkage assembly of the first locking tongue 210 and the second locking tongue 211, and also satisfying the usage requirement that the first locking tongue 210 and the second locking tongue 211 move in opposite directions.

[0083] In some embodiments, the second latch 211 is provided with an extension 27 extending along a first direction, the extension 27 and the first latch 210 are arranged opposite to each other in a second direction, and the second rack 26 is provided on the extension 27, the first direction and the second direction are perpendicular.

[0084] For example, such as Figure 1As shown, the first direction can be left and right, and the second direction can be up and down. The extension 27 can be located at the bottom of the second latch 211 and can extend to the left side of the second latch 211. The extension 27 can be located below the first latch 210. The second rack 26 can be integrally formed on the top side of the extension 27, which facilitates the relative arrangement of the first rack 25 and the second rack 26 in the up and down direction, and also facilitates the assembly with the first gear.

[0085] In some embodiments, the second latch 211 is provided with a drive rod 28, which extends along a first direction and extends to the outside of the housing 1, and the drive rod 28 is used to drive the latch 2 to switch from the locked position to the unlocked position.

[0086] For example, such as Figures 1 to 3 As shown, the drive rod 28 can be in the shape of a round rod. The drive rod 28 can be fixed to the right side of the second locking tongue 211 by means of threaded assembly, and the drive rod 28 can extend to the right side of the second locking tongue 211. The housing 1 can be provided with a through hole for the drive rod 28 to extend out.

[0087] When it is necessary to switch the two latches 2 from the locked position to the unlocked position, the locking pin 5 can be driven down first to release the lock from the second latch 211. Then, the drive rod 28 can be manually pressed to the left. At this time, the drive rod 28 can drive the second latch 211 to move to the left, and the tongue 21 of the second latch 211 can retract into the housing 1. Due to the linkage of the linkage 3, the first latch 210 can move to the right, and the tongue 21 of the first latch 210 will also retract into the housing 1. This facilitates the unlocking of the lock assembly.

[0088] In some embodiments, one of the latch 2 and the housing 1 is provided with a guide rail, and the other is provided with a guide rail groove 29. Both the guide rail and the guide rail groove 29 extend along a first direction, and the guide rail slides within the guide rail groove 29.

[0089] For example, such as Figure 1 As shown, the guide groove 29 can be a rectangular groove, and the guide groove 29 can be provided on the front and / or rear side of each latch 2, and the guide groove 29 can extend in the left and right direction. A guide rail can be provided on the inner wall of the housing 1, and the guide rail can be slidably fitted into the guide groove 29. Therefore, when the latch 2 slides left and right relative to the housing 1, the cooperation between the guide rail and the guide groove 29 can enhance the guiding and stability of the sliding.

[0090] In some embodiments, such as Figure 1 and Figure 3 As shown, the lock assembly includes an electronic control module 6, a first transmission component 7, a second transmission component 8, and a second elastic component 12.

[0091] The electronic control module 6 is housed within the housing 1. The electronic control module 6 may include a driver such as a motor 63, and the electronic control module 6 can output power to meet the usage requirements of driving the aforementioned first transmission component 7 to move.

[0092] The first transmission component 7 is slidably assembled within the housing 1 along the second direction, and the first transmission component 7 is connected to the output terminal of the electronic control module 6. The electronic control module 6 is used to drive the first transmission component 7 to slide along the second direction. For example, as Figure 3 As shown, the first transmission component 7 can be slidably assembled in the housing 1 along the vertical direction. The first transmission component 7 can be directly connected to the output end of the electronic control module 6, thereby meeting the usage requirement of driving the first transmission component 7 to move up and down by the electronic control module 6.

[0093] The second transmission component 8 is slidably assembled within the housing 1 along the second direction. The second transmission component 8 and the first transmission component 7 are slidably assembled in the second direction, and the locking pin 5 is provided on the second transmission component 8. For example, as... Figure 3 As shown, the second transmission component 8 can also be slidably assembled in the housing 1 along the vertical direction. The second transmission component 8 and the first transmission component 7 can be slidably assembled, that is, the first transmission component 7 and the second transmission component 8 can slide relative to each other in the vertical direction.

[0094] The second elastic element 12 is disposed between the first transmission element 7 and the second transmission element 8, and the second elastic element 12 is used to buffer the relative displacement of the first transmission element 7 and the second transmission element 8 in the second direction. For example, the second elastic element 12 can be a spring, the middle part of the second elastic element 12 can be connected to the first transmission element 7, and the two ends of the second elastic element 12 can abut against the second transmission element 8.

[0095] When the first transmission component 7 moves up and down under the action of the electronic control module 6, the second transmission component 8 and the locking pin 5 can be driven to move up and down by the action of the second elastic component 12, thereby satisfying the need to lock the locking tongue 2.

[0096] Secondly, since the first transmission component 7 and the second transmission component 8 can slide relative to each other in the vertical direction, when the electronic control module 6 is powered off or malfunctions, the second transmission component 8 can be driven to move up and down using a mechanical key 9, etc. At this time, the first transmission component 7 can remain stationary, thereby avoiding damage to the electronic control module 6 by mechanical unlocking, and playing a protective role.

[0097] In some embodiments, the first transmission member 7 is provided with a plate portion 74, the plate portion 74 is provided with an opening 741 penetrating the plate portion 74, the second transmission member 8 is provided with a guide groove 82, the guide groove 82 extends along a second direction, the groove wall of the guide groove 82 is provided with a slot 83, the second elastic member 12 is assembled in the opening 741, and the portion of the second elastic member 12 protruding from the surface of the plate portion 74 abuts against the groove wall of the slot 83 in the second direction.

[0098] For example, such as Figure 4 As shown, the plate 74 can be flat and integrally formed on the first transmission member 7. The opening 741 can be a rectangular hole that can penetrate the plate 74 in the left-right direction. The top and bottom walls of the opening 741 can both be provided with columnar structures. The second elastic member 12 can be assembled in the opening 741, and the top and bottom ends of the second elastic member 12 can be respectively sleeved on the outer periphery of the corresponding columnar structure.

[0099] The guide groove 82 can be a rectangular groove and can pass through the second transmission member 8 in the vertical direction. The groove wall in the middle of the guide groove 82 can be provided with a slot 83. There can be two slots 83. The two slots 83 can be located on the two groove walls of the guide groove 82 respectively, and the two slots 83 can be arranged opposite to each other in the left and right direction.

[0100] It should be noted that the radial dimension of the second elastic member 12 is greater than the width dimension of the plate portion 74 in the left and right direction. When the second elastic member 12 is assembled into the opening 741, the left and right sides of the second elastic member 12 can protrude from the left and right surfaces of the plate portion 74, respectively.

[0101] During assembly, the plate portion 74 can be inserted into the guide groove 82, and the second elastic member 12 can be simultaneously embedded in the two slots 83 and the portion of the guide groove 82 corresponding to the two slots 83. The second elastic member 12 protrudes from the left and right sides of the plate portion 74 and can be respectively fitted into the two slots 83.

[0102] In use, the plate 74 can slide along the guide groove 82, thereby satisfying the sliding assembly requirements of the first transmission member 7 and the second transmission member 8. Due to the blocking and limiting effect of the groove wall of the slot 83, the second elastic member 12 can be compressed in the vertical direction. The force generated by the second elastic member 12 satisfies the transmission requirements between the first transmission member 7 and the second transmission member 8, thereby satisfying the requirement to drive the second transmission member 8 and the locking pin 5 to move up and down.

[0103] In some embodiments, the first transmission member 7 is provided with a limiting portion 72, and the second transmission member 8 is provided with a limiting groove 81. The limiting groove 81 extends along a second direction, and the limiting portion 72 slides and engages within the limiting groove 81 to limit the stroke of the relative displacement between the first transmission member 7 and the second transmission member 8.

[0104] For example, such as Figure 3 and Figure 4 As shown, the limiting part 72 can be integrally formed on the right side of the first transmission member 7, and the limiting part 72 can be a protrusion provided in the middle of the first transmission member 7. The limiting groove 81 can be provided on the left side of the second transmission member 8, and the limiting groove 81 can be a long groove that can extend along the vertical direction.

[0105] During assembly, the limiting part 72 can fit into the limiting groove 81, and the limiting part 72 can slide up and down in the limiting groove 81. Due to the limitation of the length of the limiting groove 81, it can limit the maximum stroke of the relative displacement of the first transmission member 7 and the second transmission member 8, thus ensuring the stability of the overall structure assembly.

[0106] In some embodiments, such as Figure 1 As shown, the output end of the electronic control module 6 includes a second gear 61, and the first transmission component 7 is provided with a third rack 71. The third rack 71 can be located on the left side wall of the first transmission component 7 and extends along the second direction (vertical direction). The second gear 61 and the third rack 71 mesh with each other. In use, the rotation of the second gear 61 can drive the first transmission component 7 to move up and down, thereby satisfying the need to drive the second transmission component 8 and the locking pin 5 to move up and down.

[0107] In some embodiments, such as Figure 1 and Figure 2 As shown, the lock assembly includes a mechanical key 9, such as Figure 4 As shown, the second transmission component 8 is provided with a mating hole 84, which can be an L-shaped hole. The mechanical key 9 is inserted into the mating hole 84 to mechanically drive the displacement of the second transmission component 8 and the locking pin 5 along the second direction. Specifically, when the electronic control module 6 is powered off or malfunctions, the mechanical key 9 can be inserted into the mating hole 84, and then the second transmission component 8 can be manually driven to move downward relative to the first transmission component 7. The locking pin 5 will move downward synchronously with the second transmission component 8, thereby satisfying the need to release the locking pin 5 and the second locking tongue 211 from the insertion and locking.

[0108] In some embodiments, the electronic control module 6 includes an electronic control housing 62, one of the electronic control housing 62 and the first transmission member 7 is provided with a first sensing element 621, and the other is provided with a second sensing element 73. When the first sensing element 621 and the second sensing element 73 are opposite each other in a first direction, they generate a sensing signal for determining whether the locking pin 5 has locked the locking tongue 2.

[0109] For example, such as Figure 3 As shown, the first sensing element 621 can be a Hall sensor, the second sensing element 73 can be a magnet, the electronic control housing 62 can be L-shaped, the electronic control housing 62 can be fixed in the housing 1 by fasteners, the first sensing element 621 can be fixed in the electronic control box and can be located on the right side wall of the electronic control box, and the second sensing element 73 can be fixed on the left side wall of the first transmission element 7.

[0110] In use, the relative position of the first sensor 621 remains unchanged. When the electronic control module 6 drives the second sensor 73 to move upward, the locking pin 5 can move upward and engage the second locking tongue 211 for locking. At the same time, the first sensor 621 and the second sensor 73 can be arranged facing each other in the left-right direction and generate sensing signals. By using the generated sensing signals, it can be determined that the locking pin 5 has engaged and locked the second locking tongue 211, thus realizing status signal feedback.

[0111] In some embodiments, such as Figure 3 As shown, the lock assembly includes a push rod 10 and a third elastic element 11.

[0112] The push rod 10 is slidably fitted into the housing 1 along the second direction, and the push rod 10 is provided with a stop portion 101. For example, the push rod 10 can be in the shape of a round rod and can extend along the vertical direction. The stop portion 101 can be fixed to the middle of the push rod 10. For example, the stop portion 101 can be fitted onto the push rod 10 by means of threaded assembly, interference fit, etc. When in use, the stop portion 101 can stop against the housing wall of the housing 1 above the stop portion 101, thereby preventing the push rod 10 from coming out of the housing 1.

[0113] like Figure 3 As shown, the third elastic element 11 can be a spring. The third elastic element 11 is sleeved on the outer periphery of the top rod 10. The third elastic element 11 abuts against the stop part 101 and the housing 1. Specifically, the top end of the third elastic element 11 can abut against the stop part 101, and the bottom end of the third elastic element 11 can abut against the housing 1.

[0114] The third elastic element 11 is used to drive the push rod 10 to move along the second direction and lift the setting component when the locking tongue 2 is released from its locking position. For example, when the tongues 21 of both locking tongues 2 are released from their locking positions with the setting component, the push rod 10 and its stop 101 will move upward under the action of the third elastic element 11. Thus, the elastic force of the third elastic element 11 can be applied to the setting component by the push rod 10, thereby pushing the setting component away.

[0115] In some embodiments, the electronic control module 6 includes an electronic control housing 62, one of which, the electronic control housing 62, and the stop portion 101, is provided with a third sensor 622, and the other is provided with a fourth sensor 102. When the third sensor 622 and the fourth sensor 102 are relative to each other in a first direction, they generate a sensing signal for determining the position of the push rod 10.

[0116] For example, such as Figure 3 As shown, the third sensing element 622 can be a Hall sensor, and the fourth sensing element 102 can be a magnet. The third sensing element 622 can be installed inside the control box and can be located on the left side wall of the control box. The fourth sensing element 102 can be fixed on the right side wall of the stop part 101.

[0117] When the setting component is locked and fixed by the two locking tongues 2, the push rod 10 will be pressed down by the setting component. The third sensor 622 and the fourth sensor 102 can be arranged opposite each other in the left and right direction and generate a sensing signal. By means of the sensing signal, it can be determined that the push rod 10 has been pressed down into place, and thus it can be determined that the setting component has been locked and fixed.

[0118] In some embodiments, there are two third sensors 622, which are arranged sequentially in the second direction. One third sensor 622 is used to determine the position of the push rod 10 when the bolt 2 is in the locked position, and the other third sensor 622 is used to determine the position of the push rod 10 when the bolt 2 is in the unlocked position.

[0119] For example, the two third sensors 622 can be arranged at intervals in the vertical direction. When the push rod 10 is pushed upward by the third elastic member 11, the fourth sensor 102 on the stop part 101 can be directly opposite the upper third sensor 622, thereby determining that the setting component has been unlocked from the lock assembly. When the push rod 10 moves downward under the action of the setting component, the fourth sensor 102 on the stop part 101 can be directly opposite the lower third sensor 622, thereby determining that the setting component has been locked and fixed by the lock assembly.

[0120] In some embodiments, the upper surface of the tongue 21 can be an arc-shaped surface, which has the effect of guiding deformation, thereby facilitating the outward bending deformation of the buckle on the setting component when installing the setting component, and thus facilitating the buckle to pass over the tongue 21, which in turn facilitates the overall snap-fit ​​assembly.

[0121] In some embodiments, such as Figure 3 As shown, the electronic control module 6 may include a motor 63 and multiple reduction gears 64. The drive shaft of the motor 63 may be equipped with a worm gear. The multiple reduction gears 64 can be rotatably mounted inside the electronic control housing 62, and the multiple reduction gears 64 mesh with each other. The worm gear of the motor 63 can mesh with the reduction gear 64 at the input end, and a portion of the reduction gear 64 at the output end can form the aforementioned second gear 61 and mesh with the third rack 71 of the first transmission member 7. The electronic control module 6 is also externally connected to a wire 65, thereby facilitating the power supply of the electronic control module 6.

[0122] The vehicle according to an embodiment of the present invention is described below.

[0123] The vehicle in this embodiment of the utility model includes the lock assembly described in any of the above embodiments. Specifically, the vehicle can be an electric scooter, a two-wheeled electric vehicle, a three-wheeled electric vehicle, a balance scooter, or any other vehicle that requires the installation of a lock assembly.

[0124] In some embodiments, the vehicle includes a cover plate, which may be a foot pedal of the vehicle. The cover plate constitutes a setting component and includes two buckles, which may be U-shaped buckles. The two buckles are respectively engaged and limited by the tongues 21 of the two locking tongues 2.

[0125] It should be noted that the two buckles can be located on the left and right sides of the cover plate respectively. During assembly, the two buckles can be engaged and fixed with the tongues 21 of the locking tongues 2 on the left and right sides respectively, realizing the locking limit on the left and right sides of the cover plate. This avoids the situation in the prior art where the cover plate is easily tilted when locked by only one buckle, which helps to ensure the assembly accuracy of the cover plate and the frame. In this way, it can prevent the cover plate and the frame from being easily pried due to large gaps, and further improve the overall security and anti-theft performance.

[0126] Secondly, in order to enhance the sealing and assembly accuracy between the cover plate and the frame, elastic rubber strips are usually arranged at the mating surfaces of the frame and the cover plate. However, due to the low dimensional accuracy of the rubber strips, this reduces the positional accuracy of the assembly between the cover plate and the frame.

[0127] In this embodiment, when the setting component is locked and fixed by the two locking tongues 2, the buckle on the setting component for engaging with the tongue 21 can be clamped between the top rod 10 and the tongue 21 in the vertical direction. This clamping and locking method can compensate for the large assembly gap caused by the assembly precision of the rubber strip, and further improve the assembly precision and anti-theft performance.
