[0029] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.
[0030] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0031] The present application provides a vehicle, comprising a hood, a vehicle body and a vehicle locking device, wherein the vehicle locking device is used to lock the hood and the vehicle body.
[0032] In one implementation, please refer to Figure 1 and Figure 2 The vehicle lock device includes a lock tongue 1, a pawl 3 and a push rod 4; the lock tongue 1 rotates around a first axis; the pawl 3 rotates around a second axis, and the pawl 3 is used to abut the lock tongue 1 to lock the lock tongue 1; the push rod 4 rotates around a third axis, and the push rod 4 rotates clockwise and counterclockwise to push the pawl 3 to rotate, so that the pawl 3 is separated from the lock tongue 1 and unlocked.
[0033] Specifically, based on the above embodiment, the vehicle lock device can be installed on the vehicle body, the lock tongue 1 is used to lock the lock buckle, and the lock buckle can be installed on the engine cover. The vehicle lock device can be provided with a first rotating shaft for the lock tongue 1 to rotate, and the axis of the first rotating shaft is the first axis, and the lock tongue 1 rotates around the first rotating shaft. Optionally, a lock tongue slot is provided on the lock tongue 1, and the lock buckle extends into the lock tongue slot and is fixed under the rotation of the lock tongue 1. The vehicle lock device also includes a lock tongue spring 6, which is connected to the lock tongue 1 and is used to drive the lock tongue 1 to rotate and reset.
[0034] The pawl 3 is used to abut against the lock tongue 1 to lock the lock tongue 1. The vehicle lock device may be provided with a second shaft for the pawl 3 to rotate. The axis of the second shaft is the second axis, and the pawl 3 rotates around the second shaft. Optionally, the pawl 3 has a hook that cooperates with the lock tongue 1, and the hook is used to abut against the lock tongue 1 to limit the rotation of the lock tongue 1. The vehicle lock device also includes a pawl torsion spring 2, which is sleeved on the second shaft and connected to the pawl 3, and the pawl torsion spring 2 is used to drive the pawl 3 to rotate and reset.
[0035] In a specific embodiment, the movement of the lock tongue 1, the lock buckle and the pawl 3 can realize the locking and unlocking of the bonnet, that is, the vehicle locking device includes a locked state and an unlocked state.
[0036] In the locked state, the lock buckle extends into the lock tongue slot and cannot come out due to the restriction of the lock tongue 1. At this time, the hook of the pawl 3 abuts against the lock tongue 1 to limit the rotation of the lock tongue 1. The lock tongue spring 6 can have elastic potential energy of tension or compression.
[0037] In the process of switching from the locked state to the unlocked state, the pawl 3 rotates so that the lock tongue 1 is not restricted, and the lock tongue 1 is reset under the drive of the lock tongue spring 6, so that the lock tongue notch rotates to a position where the lock buckle can be disengaged, so that the lock buckle is disengaged. At this time, the pawl 3 drives the pawl torsion spring 2 to twist and generate elastic potential energy. After the lock tongue 1 is unlocked, the pawl torsion spring 2 can drive the pawl 3 to reset.
[0038] In the unlocked state, the lock catch does not extend into the lock tongue slot, the state of the pawl 3 is not restricted, and the lock tongue 1 keeps the lock tongue slot exposed under the traction of the lock tongue spring 6, so as to wait for the lock catch to be engaged.
[0039] In the process of switching from the unlocked state to the locked state, the lock catch extends into the lock tongue slot and pushes the lock tongue 1 to rotate (the rotation direction is opposite to the unlocking), so that the lock tongue spring 6 regains elastic potential energy and the hook of the pawl 3 can abut against the lock tongue 1.
[0040] Further, the push rod 4 is used to push the pawl 3 to rotate, so that the pawl 3 can drive the unlocking bolt 1. The vehicle lock device can be provided with a third rotating shaft for the push rod 4 to rotate, and the axis of the third rotating shaft is the third axis, and the push rod 4 rotates around the third rotating shaft. In addition, the push rod 4 can rotate clockwise or counterclockwise around the third axis, and can push the pawl 3 to rotate in both clockwise and counterclockwise rotations.
[0041] Based on the above specific embodiment, during the process of switching from the locked state to the unlocked state, after the push rod 4 rotates clockwise or counterclockwise, the pawl 3 can be pushed to rotate to unlock the lock tongue 1. And after the push rod 4 releases the thrust, the pawl 3 is reset under the drive of the pawl torsion spring 2.
[0042] Compared with the existing technology, the solution provided in the present application for the push rod 4 to rotate to push the pawl 3 is a fixed shaft solution. The push rod 4 rotates without moving, which can ensure the stability between the push rod 4 and the shaft body, thereby improving the reliability of the vehicle locking device.
[0043] Optionally, the first axis, the second axis and the third axis may be parallel.
[0044] The utility model provides a vehicle lock device, which comprises a lock tongue 1 and a ratchet 3 for abutting against the lock tongue 1 to lock, and a push rod 4 for pushing the ratchet 3 to separate from the lock tongue 1 and unlock; the push rod 4 can be used to push the ratchet 3 to rotate and unlock by rotating clockwise and counterclockwise; so in the case where an external driving force drives the push rod 4, there is no need to distinguish between clockwise and counterclockwise rotation, and the clockwise or counterclockwise driving force can achieve unlocking, so that during the assembly of the vehicle lock device, there is no need to distinguish the arrangement direction of the driving force, which can avoid the risk of reverse installation and misalignment of the parts providing the driving force, and at the same time, when the vehicle lock device is installed on the vehicle, there is no need to distinguish between the left and right steering wheels (both the left and right steering wheels can be driven to rotate), thereby realizing the universal application of the vehicle lock device.
[0045] In one implementation, please refer to Figure 3 and Figure 4 The vehicle lock device also includes a lock housing 11, and the push rod 4 includes a push rod body 42 and a push rod shaft 41 connected to each other. The push rod shaft 41 is rotatably connected to the lock housing 11, and the axis of the push rod shaft 41 is the third axis. The two ends of the push rod body 42 are respectively a first end 421 and a second end 422. The push rod shaft 41 is connected to the middle part of the push rod body 42, and the push rod shaft 41 rotates to make the first end 421 or the second end 422 push the pawl 3.
[0046] Specifically, the lock housing 11 is a carrier for carrying other parts, and the lock tongue 1, the first rotating shaft, the pawl 3, the second rotating shaft and the push rod 4 are all mounted on the lock housing 11. Optionally, the lock tongue 1, the pawl 3 and the push rod 4 are all mounted on the same surface of the lock housing 11. Optionally, the vehicle lock device further includes a lock body bracket 5, which is connected to the lock housing 11 to fix the above parts.
[0047] The push rod 4 is of a "bamboo dragonfly" style, and includes a push rod body 42 and a push rod shaft 41. The push rod body 42 and the push rod shaft 41 are an integrated structure, and the push rod shaft 41 is the third rotating shaft in the above embodiment. The lock housing 11 is provided with an axis hole for the push rod shaft 41 to pass through, and the push rod shaft 41 is arranged therein and can rotate in the axis hole. The push rod 4 is of a "bamboo dragonfly" style, has a simple structure, is extremely easy to design, and is easy to implement.
[0048] Optionally, the push rod body 42 may be in the shape of an elongated strip and include a first end 421 and a second end 422 that are separated from each other, and the push rod shaft 41 is connected to the middle of the push rod body 42, that is, the distances from the push rod shaft 41 to the first end 421 and the second end 422 are equal or similar. The push rod body 42 may include a side edge, and the side edge is used to contact the pawl 3 in a locked state or an unlocked state, and then as the push rod 4 rotates, the first end 421 or the second end 422 of the push rod body 42 pushes the pawl 3.
[0049] It can be understood that the rotation radius of the push rod body 42 is the distance from the third axis to the first end 421 or the second end 422. As long as the pawl 3 is set within the rotation radius of the push rod body 42, the first end 421 or the second end 422 can push the pawl 3 when the push rod body 42 rotates.
[0050] In one implementation, please refer to Figure 3 and Figure 4 The vehicle lock device further comprises a pull rod 8, which is located on a side of the lock housing 11 facing away from the push rod body 42, and is connected to the push rod shaft 41, and the pull rod 8 drives the push rod 4 to rotate.
[0051] Specifically, the push rod shaft 41 passes through the lock housing 11 and extends into the side of the lock housing 11 facing away from the push rod body 42. A pull rod 8 is connected to the push rod shaft 41. The pull rod 8 is used to bear external force and drive the push rod shaft 41 to rotate (including clockwise or counterclockwise).
[0052] Optionally, the pull rod 8 and the push rod 4 can be detachably connected, including but not limited to threaded connection, snap connection, magnetic connection, etc., and the specific connection method is not limited.
[0053] It can be understood that the main function of the push rod 4 is to push the pawl 3 to rotate so as to release the lock tongue 1 and put the lock body into an unlocked state. When the hood lock needs to be opened, the pull rod 8 drives the push rod 4 to rotate together, and the push rod 4 pushes the pawl 3, so that the pawl 3 rotates to release the restriction on the lock tongue 1, thereby opening the hood lock.
[0054] In the utility model, the pull rod 8 is fixedly connected to the push rod shaft 41, so that the two are coaxially designed, the push rod 4 is inside the lock shell 11, and the pull rod 8 is outside the lock shell 11. The pull rod 8 receives external driving force, and the pull rod 8 rotates clockwise or counterclockwise, and drives the internal push rod 4 to rotate in the same direction around its third axis. The push rod 4 pushes the pawl 3 through its first end 421 or second end 422 to rotate the pawl 3 to reach the unlocking state. Compared with the prior art, the push rod 4 always rotates with the push rod shaft 41 as the axis and will not move. The push rod body 42, the push rod shaft 41 and the pull rod 8 jointly constrain the movement of the push rod 4. The force requirement of the push rod 4 itself is low, and the structural stability is high; and the lock shell 11 only needs to be provided with a through hole matching the push rod shaft 41, and the design difficulty of the lock shell 11 is relatively low.
[0055] In addition, the push rod 4 in the utility model rotates clockwise and counterclockwise, and has a high balance. Both the forward and reverse movements are the same movement mode, which can be achieved by the push rod 4 cooperating with the pull rod 8. There is no need for too many parts design, so that the vehicle lock device is simple as a whole and easy to produce; and the accuracy requirements for this design in reality are relatively low, and it can be completed as long as the pawl 3 can be within the rotation radius of the push rod body 42, and the unlocking effect is not easy to fail.
[0056] In one implementation, please refer to Figure 4 The pull rod 8 includes a ring body 81, which is sleeved on the outer circumference of the push rod shaft 41; the ring body 81 has a first matching portion, and the push rod shaft 41 has a second matching portion, and the first matching portion and the second matching portion are matched and connected to make the ring body 81 and the push rod shaft 41 relatively fixed.
[0057] Specifically, the ring body 81 is an annular part, and after the push rod shaft 41 passes through the lock housing 11, the ring body 81 is sleeved on the outer circumference of the push rod shaft 41. The first matching portion and the second matching portion are matched and connected, so that the ring body 81 and the push rod shaft 41 are relatively fixed.
[0058] Optionally, the first matching portion may be a boss, a groove, etc. The second matching portion may be a groove, a boss, etc. The boss and the groove may be circular, oval or square, etc. It is understandable that if the first matching portion is a boss, then the second matching portion is a groove.
[0059] In one implementation, please refer to Figure 4 The first matching portion is a boss 811 on the inner wall surface of the ring body 81 , and the second matching portion is a groove 411 on the outer wall surface of the push rod shaft 41 , and the boss 811 extends into the groove 411 .
[0060] Specifically, the boss 811 is formed on the inner wall surface of the ring body 81, that is, a protruding structure is formed from the inner wall surface of the ring body 81. The groove 411 is formed on the outer surface of the push rod shaft 41, and the groove 411 extends axially from the end of the push rod shaft 41 facing away from the push rod body 42, so that the ring body 81 can be slidably inserted from the end of the push rod shaft 41 facing away from the push rod body 42.
[0061] Optionally, the number of the bosses 811 and the grooves 411 may be one or more, and the specific number is not limited.
[0062] In one implementation, please refer to Figure 4 The pull rod 8 includes a rod body 82 connected to a ring body 81, and one end of the rod body 82 away from the ring body 81 is curled to form a pulling hole 83, and the rod body 82 includes a first surface and a second surface opposite to each other; the vehicle locking device includes a cable 7, and the cable 7 passes through the pulling hole 83 from the first surface, or the cable 7 passes through the pulling hole 83 from the second surface.
[0063] Specifically, the rod body 82 can be connected to the outer wall surface of the ring body 81 facing away from the boss 811. The rod body 82 includes a straight section and a curved section, wherein the straight section connects the ring body 81 and extends in a direction away from the ring body 81, and the curved section is connected to one end of the straight section away from the ring body 81. The curved section is curled and extends inward to form a pulling hole 83, and the pulling hole 83 can be passed through by the cable 7.
[0064] Optionally, the rod body 82 includes a first surface and a second surface opposite to each other, wherein the first surface is Figure 5The right side of the middle rod body 82, the second side is Figure 7 On the left side of the middle rod body 82 , the cable 7 can pass through the pull hole 83 from the first surface, or pass through the pull hole 83 from the second surface.
[0065] It can be understood that after the cable 7 passes through the pull hole 83, it is clamped with the pull rod 8, and the cable 7 is driven by the external driving force to drive the pull rod 8 to rotate (including clockwise and counterclockwise). When the cable 7 passes through the first side, it can drive the pull rod 8 to rotate counterclockwise; when the cable 7 passes through the second side, it can drive the pull rod 8 to rotate clockwise. Therefore, the main function of the pull rod 8 is to connect the cable 7 and drive the push rod 4 to rotate.
[0066] In a specific embodiment, the vehicle lock device provided by the present application can be applicable to left-hand drive vehicles and right-hand drive vehicles. When the vehicle lock device is used for a left-hand drive vehicle, such as Figure 5 and Figure 6 As shown, the cable 7 penetrates from the left side of the vehicle (compared to Figure 6 ), and is engaged with the pull hole 83 above the pull rod 8, such as Figure 6 As shown, the cable 7 pulls the rod 8 to rotate around the axis to the left side of the vehicle (counterclockwise), the push rod 4 follows the rod 8 to rotate to the left side of the vehicle (counterclockwise), the first end 421 of the push rod body 42 pushes the pawl 3 to move to the left side of the vehicle (clockwise), the lock tongue 1 is released, and rotates counterclockwise under the action of the restoring force of the lock tongue spring 6, and the lock body is in an open state. The tension of the cable 7 is canceled, the rod 8 and the push rod 4 return to the initial state under the action of the rod reset torsion spring 9, and the pawl 3 is reset under the action of the pawl torsion spring 2.
[0067] When the bonnet lock is used in right-hand drive vehicles, Figure 7 and Figure 8 As shown, the cable 7 penetrates from the right side of the vehicle (compared to Figure 8 ), and is engaged with the pull hole 83 above the pull rod 8, such as Figure 8 As shown, the cable 7 pulls the rod 8 to rotate around the axis to the right side of the vehicle (clockwise), and the push rod 4 follows the rod 8 to rotate to the right side of the vehicle (clockwise), and the second end 422 of the push rod body 42 pushes the pawl 3 to move to the left side of the vehicle (clockwise), and the lock tongue 1 is released and rotates counterclockwise under the action of the restoring force of the lock tongue spring 6, and the lock body is in an open state. The tension of the cable 7 is canceled, and the rod 8 and the push rod 4 return to the initial state under the action of the rod reset torsion spring 9, and the pawl 3 is reset under the action of the pawl torsion spring 2.
[0068] It can be understood that the push rod 4 and the pull rod 8 structure are the main components for realizing the common use of the left and right rudders. The main function of the pull rod 8 is to provide a fixing point and force transmission function for the cable 7. The pull rod 8 and the push rod 4 are positioned by the boss 811 and the groove 411. The rotation of the push rod shaft 41 is used to convert the displacement of the cable 7 to the first end 421 and the second end 422 on the push rod body 42. The push rod 4 will contact the pawl 3 in both forward and reverse rotations to achieve movement.
[0069] In one implementation, please refer to Figure 4 The vehicle locking device further includes a fixing member 10 , which is inserted into a side of the push rod shaft 41 facing away from the push rod body 42 , and is used to fix the pull rod 8 .
[0070] Specifically, the fixing member 10 can be a fastening screw, and a screw hole can be opened on the end surface of the push rod shaft 41 facing away from the push rod body 42, so that the fixing member 10 can be inserted into the screw hole to fix the pull rod 8. Through the boss 811 on the pull rod 8 and the groove 411 on the push rod shaft 41, in combination with the positioning member, the six degrees of freedom (including up, down, left, right, front, and back) between the pull rod 8 and the push rod 4 can be limited.
[0071] In one implementation, please refer to Figure 4 The vehicle locking device also includes a pull rod reset torsion spring 9, which is sleeved on the push rod shaft 41.
[0072] Specifically, the pull rod reset torsion spring 9 is used to drive the pull rod 8 to reset the push rod 4. In the process of switching from the locked state to the unlocked state, the pull rod 8 rotates and drives the pull rod reset torsion spring 9 to generate elastic potential energy. After the external driving force is removed, the pull rod reset torsion spring 9 drives the pull rod 8 to reset.
[0073] In a specific embodiment, the pull rod reset torsion spring 9 is coaxially arranged with the pull rod 8, one end of the pull rod reset torsion spring 9 is clamped with the pull rod 8, and the other end of the pull rod reset torsion spring 9 is clamped with the lock housing 11. When the pull rod 8 rotates around the axis under the tension of the cable 7, it drives the push rod 4 to rotate together. After the tension disappears, the pull rod reset torsion spring 9 restores the pull rod 8 to its initial state.
[0074] In one implementation, please refer to Figure 2 The pawl 3 includes a flange 31, and the side of the flange 31 facing the push rod 4 is one of a rectangle, a diamond, and an ellipse. The push rod 4 pushes the flange 31 to rotate the pawl 3.
[0075] Specifically, the flange 31 of the pawl 3 can be fitted with the side of the push rod body 42, and the length of the flange 31 can be the same as the length of the push rod body 42 (the distance from the first end 421 to the second end 422), so that the flange 31 can provide a larger contact area and enable the first end 421 and the second end 422 to push the pawl 3 smoothly through the flange 31.
