Description

Technical Field

[0001] This application relates to the technical field of automotive door locks, and in particular to a locking structure for automotive locks. Background Technology

[0002] Car door locks are an important component of a car body, a special part that integrates security, aesthetics, and craftsmanship. With the development of the automotive industry, the functions and types of car door locks are becoming increasingly diverse. Passengers are also becoming more knowledgeable about cars and have higher and higher requirements for car comfort. Among these, the user-friendly opening and closing of car doors is receiving increasing attention from customers and car manufacturers.

[0003] Existing vehicle locks include a housing, on which a stop pawl and a stop wheel are rotatably connected. The stop wheel includes a latch that engages with the lock bolt. One end of the stop pawl has a protrusion offset from its axis of rotation. The stop wheel has a semi-locking engagement portion and a fully-locking engagement portion that engage with the protrusion. Engaging the protrusion with either the semi-locking or fully-locking engagement portion puts the lock in a semi-locked or fully-locked state. The housing has a torsion spring for rotating the stop pawl until the protrusion engages with the semi-locking or fully-locking engagement portion. The housing also has an inner opening mechanism and an outer opening mechanism for controlling the opening and closing of the lock. Both mechanisms can control the rotation of the stop pawl, thereby disengaging the stop pawl from the stop wheel.

[0004] However, in actual use, it was found that when controlling the rotation of the stop pawl to disengage it from the stop wheel, the user has difficulty controlling the angle of rotation of the stop pawl. This can easily cause the stop pawl to collide with other parts inside the housing and make noise. In severe cases, it can also affect the subsequent engagement between the stop pawl and the stop wheel, thus affecting the user's experience. Summary of the Invention

[0005] In order to reduce noise during the opening and closing of the vehicle lock while improving the reliability of the engagement between the stop pawl and the stop wheel, this application provides a vehicle lock locking structure.

[0006] The vehicle lock locking structure provided in this application adopts the following technical solution: A vehicle lock locking structure includes a positioning pin connected to a stop pawl. The positioning pin is located at one end of the stop pawl where a protrusion is provided. The end of the positioning pin away from the stop pawl passes through a housing. A positioning groove is provided on the housing for the positioning pin to swing. When the positioning pin slides along the positioning groove, it can drive the stop pawl to rotate. The housing is rotatably connected to a linkage plate at one end away from the stop claw. A guide block is rotatably connected to the linkage plate. The rotation axis of the guide block is offset from the rotation axis of the linkage plate. The guide block is located between the linkage plate and the housing. The guide block is mounted on the linkage plate by a mounting assembly. The end of the guide block away from the linkage plate has a receiving cavity for the insertion of a positioning pin. The housing is provided with a control component for controlling the rotation angle of the guide block. The housing is provided with a linkage component for driving the linkage plate to rotate. When the linkage plate rotates, it can drive the positioning pin to slide along the positioning groove through the rotation of the guide block. The housing is provided with a locking mechanism that drives the guide block to rotate away from the positioning pin until it is separated from the positioning pin.

[0007] By adopting the above technical solution, the rotation angle of the stop pawl is limited by the setting of the positioning groove, making it less likely for the stop pawl to rotate and collide with other components in the housing, thus reducing the noise generated during the opening and closing of the vehicle lock; when the linkage plate rotates under the action of the linkage component, the guide block can drive the positioning pin to swing along the positioning groove under the push of the guide block, thereby driving the stop pawl to rotate to disengage from the stop wheel, making it easier to control the rotation of the stop pawl.

[0008] The locking mechanism controls the guide block to rotate away from the positioning pin until it separates from the positioning pin, so that when the linkage plate rotates under the action of the linkage component, it can only drive the guide block to rotate, which facilitates the locking of the vehicle lock.

[0009] Preferably, the locking mechanism includes a locking plate rotatably connected to the housing. The housing is provided with a central control device for controlling the rotation of the locking plate. The locking plate is located at the end of the guide block away from the housing. The end of the guide block away from the housing is provided with a limiting pin. The locking plate is provided with a limiting baffle extending toward the housing. After the locking plate rotates, the limiting baffle separates from or engages with the limiting pin. When the limiting baffle separates from the limiting pin, the vehicle lock is in a normal state. When the limiting baffle engages with the limiting pin and the guide block rotates to separate from the positioning pin under the cooperation of the limiting baffle and the limiting pin, the vehicle lock is in a locked state.

[0010] By adopting the above technical solution, when the locking plate rotates to the point where the limit baffle separates from the limit pin, the vehicle lock is in a normal state. That is, when the linkage plate rotates under the action of the linkage component, it can drive the positioning pin to slide along the positioning groove through the rotation of the guide block, thereby releasing the engagement between the stop pawl and the stop wheel. When the limit baffle and the limit pin are in contact and the guide block rotates to the point where it separates from the positioning pin under the cooperation of the limit baffle and the limit pin, the vehicle lock is in a locked state. That is, when the linkage plate rotates under the action of the linkage component, although it can drive the guide block to rotate through the rotation of the linkage plate, since the guide block has rotated to the point where it separates from the positioning pin, the rotation of the guide block is not easy to drive the positioning pin to slide along the positioning groove. The stop pawl and the stop wheel remain engaged. During the movement of the vehicle or after the passengers leave the vehicle, it is not easy to open the door, effectively ensuring personal safety and property safety.

[0011] Preferably, when the locking plate rotates to the locked state, the limiting baffle is arranged in an arc shape with the rotation axis of the stop pawl as the center.

[0012] By adopting the above technical solution, when the vehicle lock is in the locked state, the rotation of the linkage plate will drive the guide block to rotate. However, under the restriction of the limit baffle, the limit pin can only rotate around the rotation axis of the stop pawl, so that the limit pin should not collide with other parts in the housing and generate noise during the vehicle's operation.

[0013] Preferably, the control component includes a reinforcing plate disposed at the end of the housing away from the stop claw. When the locking plate rotates to the normal state of the vehicle lock, the end of the guide block away from the linkage plate is in contact with the side wall of the reinforcing plate. When the linkage plate rotates, the guide block can slide along the side wall of the reinforcing plate. The linkage plate is provided with a linkage elastic element for controlling the reset of the guide block.

[0014] By adopting the above technical solution, the strength of the housing itself is increased by setting the reinforcing plate, and the lines of the side wall of the reinforcing plate guide the rotation of the guide block. When the stop wheel and the stop pawl are in the meshing state, there is a certain gap between the guide block and the positioning pin, so that the guide block is not easy to make noise when it engages with the positioning pin during vehicle operation. Through the action of the linkage elastic element, the guide block can be reset after rotation.

[0015] Preferably, the guide block is provided with a linkage shaft for installing the linkage elastic element, the linkage elastic element is sleeved on the linkage shaft, the linkage shaft is provided with a limiting block for restricting the linkage elastic element from disengaging from the installation shaft, and the linkage elastic element is located between the limiting block and the guide block.

[0016] By adopting the above technical solution and setting the limiting block, the installed linkage torsion spring is restricted from sliding away from the guide block until it disengages from the linkage shaft, thereby improving the connection strength between the linkage torsion spring and the linkage shaft.

[0017] Preferably, the mounting assembly includes a mounting shaft disposed at the end of the guide block opposite to the linkage shaft. The linkage plate has a mounting through hole for the mounting shaft to pass through and rotate. A mating block is connected to the side wall of the mounting shaft. A mating through hole corresponding to the mating block is formed on the inner wall of the mounting through hole. The mating block fits against the end face of the linkage plate opposite to the guide block. The length of the connection between the mating block and the mounting shaft is less than the diameter of the mounting shaft.

[0018] By adopting the above technical solution, the mating block on the mounting shaft is aligned with the mating through hole and passes through the mating through hole, so that the guide block is installed on the linkage plate. Rotating the guide block causes the mating block and the mating through hole to be misaligned. Since the length of the connection between the mating block and the mounting shaft is less than the diameter of the mounting shaft, the position of the mounting shaft is limited, so that the guide block can only rotate under the action of the linkage torsion spring during the rotation of the linkage plate and is not easy to slip relative to the linkage plate, thereby improving the reliability of the positioning pin swinging by the rotation of the guide block.

[0019] Preferably, the mounting assembly includes a fixed shaft disposed at the end of the guide block opposite to the linkage shaft and a fixed block connected to the linkage plate. The fixed block has a fixing groove for the fixed shaft to be embedded in, and the end of the fixing groove near the linkage plate passes through the linkage plate. The fixed shaft is provided with a rotating block, and the inner wall of the fixed groove is provided with a rotating groove for the rotating block to rotate. The inner wall of the rotating groove is provided with a fixing ring for restricting the rotating block from sliding out of the rotating groove. The fixing ring includes a fixing part connected to the inner wall of the rotating groove and a sliding part slidably disposed in the rotating groove. After the sliding part slides, the rotating block can be embedded in the rotating groove. The fixed block is provided with a fixing elastic element for pushing the sliding part to slide out of the rotating groove.

[0020] By adopting the above technical solution, the rotating block on the fixed shaft is aligned with the sliding part, and then the guide block is pushed towards the fixed block until the gap between the fixed part and the sliding part is larger than the rotating block. Then the guide block is rotated so that the rotating block is embedded in the rotating groove, and the sliding part is reset under the action of the fixed elastic element. With the cooperation of the fixed ring and the rotating block, the fixed shaft is not easy to slide out of the fixed groove, which improves the reliability of the guide block installed on the linkage plate.

[0021] Preferably, a support column coaxial with the fixing groove is slidably connected to the fixing block, the support column is slidably disposed in the fixing groove, a support groove for the support column to be embedded is coaxially opened on the fixing shaft, the sliding part is connected to the support column, the support column can push the fixing shaft to slide until the rotating block and the fixing ring are in contact, an operating groove communicating with the support groove is opened on the fixing shaft, and the end of the operating groove away from the support groove extends to the outside of the fixing shaft.

[0022] By adopting the above technical solution, since the support column is connected to the sliding part, the support column can slide under the action of the fixed elastic element. The support column provides positioning and guidance for the sliding of the fixed shaft into the fixed groove, and also provides support for the fixed shaft. When the sliding part resets under the action of the fixed elastic element, the fixed shaft can be pushed by the support column to make the rotating block fit against the fixed ring. During the rotation of the guide block, the guide block is less likely to slip relative to the linkage plate, improving the stability of the guide block mounted on the linkage plate. Furthermore, the operating groove allows the support column to be pushed towards the fixed block using an operating tool that works with the operating groove, enabling the sliding part to slide until the rotating plate can rotate out of the rotating groove, facilitating the loading and unloading of the guide block on the linkage plate.

[0023] Preferably, when the stop pawl engages with the stop wheel, there is a gap between the positioning pin and the cavity wall of the receiving cavity.

[0024] By adopting the above technical solution, the positioning pin is less likely to collide with the cavity wall of the receiving cavity and generate noise during the opening and closing of the car door, thus improving the user's comfort.

[0025] Preferably, the housing is further provided with a buffer block that is elastically arranged, and the housing is provided with a buffer seat for the buffer block to fit into. When the stop pawl engages with the stop wheel, the side wall of the stop pawl away from the positioning pin is in contact with the buffer block.

[0026] By adopting the above technical solution and setting up a flexible buffer block, the noise generated during the opening and closing of the vehicle lock is further reduced effectively.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. Because there is a gap between the locating pin and the cavity wall when the stop pawl and the stop wheel are engaged, the locating pin is less likely to collide with the cavity wall and generate noise during the opening and closing of the car door; the reinforcement plate increases the strength of the housing itself, and the lines of the side wall of the reinforcement plate guide the rotation of the guide block, so that when the stop wheel and the stop pawl are engaged, there is a certain gap between the guide block and the locating pin, making it less likely for the guide block to engage with the locating pin and generate noise during the vehicle's operation; 2. When the locking plate rotates to the point where the limit baffle separates from the limit pin, the vehicle lock is in normal condition. The end of the guide block away from the linkage plate is in contact with the side wall of the reinforcing plate. That is, when the linkage plate rotates, it can drive the positioning pin to slide along the positioning groove through the rotation of the guide block, thereby releasing the engagement between the stop pawl and the stop wheel. When the locking plate rotates to the point where the limit baffle and the limit pin are in contact and the guide block rotates to the point where it separates from the positioning pin under the cooperation of the limit baffle and the limit pin, the vehicle lock is in locked condition. That is, although the rotation of the linkage plate can drive the guide block to rotate, since the guide block has rotated to the point where it separates from the positioning pin, the rotation of the guide block is not easy to drive the positioning pin to slide along the positioning groove. The stop pawl and the stop wheel remain in engagement. During the movement of the vehicle or after the passengers leave the vehicle, the door is not easy to open, effectively ensuring personal safety and property safety. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0038] This application discloses a vehicle lock locking structure.

[0039] Example 1: Reference Figure 1 and Figure 3 The car lock includes a housing 1, on which a stop pawl 11 and a stop wheel 12 are rotatably connected. The stop wheel 12 includes a latch that engages with the lock. One end of the stop pawl 11 is provided with a protrusion 111, which is offset from the rotation axis of the stop pawl 11. The stop wheel 12 is provided with a half-lock engagement part 121 and a full-lock engagement part 122 that engage with the protrusion 111. The engagement of the protrusion 111 with the half-lock engagement part 121 or the full-lock engagement part 122 causes the car lock to be in a half-lock or full-lock state. A positioning pin 112 is fixedly connected to the stop pawl 11. The positioning pin 112 is located at the end of the stop pawl 11 where the protrusion 111 is located. The end of the positioning pin 112 away from the stop pawl 11 passes through the housing 1. A positioning groove 13 for the positioning pin 112 to swing is provided through the housing 1. The positioning groove 13 is waist-shaped and the curvature of the positioning groove 13 is centered on the rotation axis of the stop pawl 11. When the positioning pin 112 slides along the positioning groove 13, it can drive the stop pawl 11 to rotate to engage or disengage with the stop wheel 12.

[0040] Reference Figure 1The housing 1 is also provided with a buffer block 14 that is elastically set, and the housing 1 is also provided with a buffer seat 141 for mounting the buffer block 14. The buffer block 14 and the buffer seat 141 are interference fit. When the stop pawl 11 rotates to engage with the stop wheel 12, the side wall of the end of the stop pawl 11 away from the positioning pin 112 is made to fit with the elastic buffer block 14, which further effectively reduces the noise generated during the opening and closing of the car lock.

[0041] Reference Figure 2 , Figure 3 and Figure 4 The housing 1 is rotatably connected to a linkage plate 2 at one end away from the stop claw 11. The housing 1 is provided with a linkage component for driving the linkage plate 2 to rotate. The linkage component includes an outer opening connecting plate 15 and an inner opening push plate 16. The outer opening connecting plate 15 is oscillatingly disposed on the housing 1 and is rotatably connected to the linkage plate 2. When the outer opening connecting plate 15 slides toward the linkage plate 2, it rotates relative to the linkage plate 2 and can drive the linkage plate 2 to rotate. The inner opening push plate 16 is rotatably connected to the housing 1. The linkage plate 2 is provided with a push plate 21 that cooperates with the inner opening push plate 16. After the inner opening push plate 16 rotates, it first fits against the push plate 21. As the inner opening push plate 16 rotates, the linkage plate 2 can rotate under the cooperation of the inner opening push plate 16 and the push plate 21. The linkage plate 2 that rotates under the action of the outer opening connecting plate 15 or the inner opening push plate 16 rotates in the same direction.

[0042] Reference Figure 4 and Figure 5 A guide block 3 is rotatably connected to the linkage plate 2. The rotation axis of the guide block 3 is offset from the rotation axis of the linkage plate 2. The guide block 3 is located between the linkage plate 2 and the housing 1. The end of the guide block 3 away from the linkage plate 2 has a receiving cavity 31 for the positioning pin 112 to be inserted. The housing 1 is provided with a control component for controlling the rotation angle of the guide block 3. The control component includes a reinforcing plate 17 fixed to the end of the housing 1 away from the stop claw 11. The reinforcing plate 17 is attached to the housing 1. The end of the guide block 3 away from the linkage plate 2 is attached to the side wall of the reinforcing plate 17. The linkage plate 2 is provided with a linkage elastic component for driving the guide block 3 to rotate toward the positioning pin 112. In this embodiment, the linkage elastic component is a linkage torsion spring 22. The two ends of the linkage torsion spring 22 are fixed to the linkage plate 2 and the guide block 3, respectively. When the linkage plate 2 rotates, the guide block 3 can slide along the side wall of the reinforcing plate 17. The linkage torsion spring 22 facilitates the reset of the guide block 3 after rotation.

[0043] Reference Figure 5 and Figure 6 The guide block 3 is provided with a linkage shaft 32 for installing the linkage torsion spring 22 at one end away from the housing 1. The linkage torsion spring 22 is sleeved on the linkage shaft 32. A limit block 321 is also fixed on the linkage shaft 32. The linkage torsion spring 22 is located between the limit block 321 and the guide block 3.

[0044] When the stop pawl 11 and the stop wheel 12 are engaged, there is a gap between the positioning pin 112 and the cavity wall of the receiving cavity 31. This makes it less likely for the positioning pin 112 to collide with the cavity wall of the receiving cavity 31 and generate noise during the opening and closing of the vehicle body, thus improving the user's comfort. When the linkage plate 2 rotates under the action of the outward opening connecting plate 15 or the inward opening push plate 16, the guide block 3 can be attached to the side wall of the reinforcing plate 17 and slide along the side wall of the reinforcing plate 17 under the action of the linkage torsion spring 22. During this process, the guide block 3 first rotates until the positioning pin 112 is attached to the cavity wall of the receiving cavity 31. Then, as the guide block 3 rotates, the positioning pin 112 can slide along the positioning groove 13 under the push of the guide block 3, thereby driving the stop pawl 11 to rotate to disengage from the stop wheel 12.

[0045] Reference Figure 2 and Figure 4 The housing 1 is also provided with a reset torsion spring 23 for controlling the reset of the linkage plate. The two ends of the reset torsion spring 23 are fixed to the housing 1 and the linkage plate 2 respectively. By setting the reset torsion spring 23, the linkage plate 2 can be reset after being rotated under the action of the outward-opening connecting plate 15 or the inward-opening push plate 16.

[0046] Reference Figure 2 , Figure 3 and Figure 4 The housing 1 is provided with a locking mechanism 18 that drives the guide block 3 to rotate away from the positioning pin 112 until it is separated from the positioning pin 112. The locking mechanism 18 includes a locking plate 4 rotatably connected to the housing 1. The housing 1 is provided with a central control control for controlling the rotation of the locking plate 4. The central control control includes a central control connecting plate 181 slidably disposed on the housing 1. The central control connecting plate 181 is rotatably connected to the locking plate 4. When the central control connecting plate 181 slides toward the locking plate 4, it has its own rotation relative to the locking plate 4 and can drive the locking plate 4 to rotate. The locking plate 4 is located at the end of the guide block 3 away from the housing 1, and a limiting pin 33 is fixed at the end of the guide block 3 away from the housing 1. A limiting baffle 41 is fixed on the locking plate 4. The limiting baffle 41 extends toward the housing 1. After the locking plate 4 rotates, the limiting baffle 41 separates from or fits with the limiting pin 33.

[0047] Reference Figure 5 and Figure 6When the locking plate 4 rotates until the limiting baffle 41 separates from the limiting pin 33, the vehicle lock is in normal condition. The end of the guide block 3 away from the linkage plate 2 is in contact with the side wall of the reinforcing plate 17. That is, when the linkage plate 2 rotates under the action of the outward opening connecting plate 15 or the inward opening push plate 16, it can drive the positioning pin 112 to slide along the positioning slide groove 13 through the rotation of the guide block 3, thereby releasing the engagement between the stop pawl 11 and the stop wheel 12. When the limiting baffle 41 is in contact with the limiting pin 33 and the guide block 3 is in contact with the limiting baffle 41 and the limiting pin 33, the lock is in normal condition. When the limit pin 33 rotates to separate from the positioning pin 112, the vehicle lock is in a locked state. That is, when the linkage plate 2 rotates under the action of the outward opening connecting plate 15 or the inward opening push plate 16, the guide block 3 separates from the reinforcing plate 17. At this time, although the rotation of the linkage plate 2 can drive the guide block 3 to rotate, since the guide block 3 has rotated to the state of being separated from the positioning pin 112, the rotation of the guide block 3 is not easy to drive the positioning pin 112 to swing along the positioning slide groove 13, and the stop pawl 11 and the stop wheel 12 remain engaged. Through the setting of the locking mechanism 18, the vehicle lock is kept in a closed state, which restricts passengers from leaving the vehicle and opening the door during the movement of the vehicle, effectively ensuring personal safety and property safety.

[0048] Reference Figure 6 When the locking plate 4 rotates to the locked state, the limiting baffle 41 is set in an arc shape with the rotation axis of the stop pawl 11 as the center. When the linkage plate 2 rotates under the action of the outer opening connecting plate 15 or the inner opening push plate 16, the guide block 3 that rotates accordingly will rotate with the rotation axis of the stop pawl 11 as the center under the cooperation of the limiting pin 33 and the limiting baffle 41. This makes it possible for the limiting pin 33 to collide with other parts inside the housing 1 and generate noise during the driving process of the vehicle.

[0049] Reference Figure 2 and Figure 6 The guide block 3 is mounted on the linkage plate 2 via an installation assembly. The installation assembly includes an installation shaft 5 fixed to the guide block 3. The installation shaft 5 is located at the end of the guide block 3 away from the linkage shaft 32 and is coaxial with the linkage shaft 32. The guide block 3 rotates around the installation shaft 5 as the rotation axis. The linkage plate 2 is provided with a corresponding installation through hole 51 for the installation shaft 5 to pass through and rotate. A mating block 52 is also fixed on the side wall of the installation shaft 5. A mating through hole 521 corresponding to the mating block 52 is provided on the inner wall of the installation through hole 51. After the guide block 3 rotates, the mating block 52 fits against the end face of the linkage plate 2 away from the guide block 3. After the control of the guide block 3 is released, the guide block 3 can be reset under the action of the linkage torsion spring 22, that is, rotated to the state of fitting against the side wall of the reinforcing plate 17. The length of the connection between the mating block 52 and the installation shaft 5 is less than the diameter of the installation shaft 5, which limits the position of the installation shaft 5.

[0050] Example 2: The difference from Example 1 is that: (Refer to...) Figure 7 and Figure 8 The mounting components include a fixed shaft 6 fixed to the guide block 3 and a fixed block 7 fixed to the linkage plate 2. The fixed shaft 6 is located at the end of the guide block 3 away from the linkage shaft 32 and is coaxial with the linkage shaft 32. The guide block 3 rotates about the fixed shaft 6 as the axis of rotation. The fixed block 7 has a fixed groove 71 for the fixed shaft 6 to be inserted and rotated. The end of the fixed groove 71 near the linkage plate 2 passes through the linkage plate 2.

[0051] Reference Figure 8 Four rotating blocks 61 are fixed on the fixed shaft 6. The four rotating blocks 61 are arranged in a circular array with the axis of the fixed shaft 6 as the center. The inner wall of the fixed groove 71 is provided with a rotating groove 711 for the rotating blocks 61 to rotate. The inner wall of the rotating groove 711 is provided with a fixing ring 72 for restricting the rotating blocks 61 from sliding out of the rotating groove 711. The inner wall of the fixing ring 72 fits against the outer wall of the fixed shaft 6, and the outer wall of the fixing ring 72 fits against the inner wall of the rotating groove 711. With the cooperation of the fixing ring 72 and the rotating blocks 61, the fixed shaft 6 can be rotatably set in the fixed groove 71 and the fixed shaft 6 is not easy to move out of the fixed groove 71, so that the guide block 3 can be installed on the linkage plate 2.

[0052] Reference Figure 8 The fixing ring 72 includes four fixing parts 721 fixed to the inner wall of the rotating groove 711 and four sliding parts 722 slidably disposed in the rotating groove 711. The sliding parts 722 slide along the length direction of the rotating groove 711. The four fixing parts 721 and the four sliding parts 722 are arranged in a circular array with the axis of the rotating groove 711 as the center, and the fixing parts 721 and the sliding parts 722 are spaced apart. The sliding parts 722 are correspondingly disposed with the rotating block 61.

[0053] Reference Figure 8 The fixed block 7 is also slidably connected to a support column 73 coaxial with the fixed groove 71. The four rotating blocks 61 are connected to the support column 73 by a connecting rod 731. The two ends of the connecting rod 731 are fixed to the support column 73 and the rotating block 61 respectively. The support column 73 is slidably disposed in the fixed groove 71 and slides along the length direction of the fixed groove 71, extending to the outside of the fixed groove 71. The fixed block 7 is provided with a fixed elastic element for pushing the sliding part 722 to slide outward toward the rotating groove 711. In this embodiment, the fixed elastic element is a fixed spring 732. One end of the fixed spring 732 is fixed to the inner wall of the fixed groove 71, and the other end of the fixed spring 732 is fixed to the support column 73. With the setting of the fixed spring 732, the support column 73 and the sliding part 722 can be pushed to slide outward toward the rotating groove 711 until the sliding part and the fixed part 721 are on the same plane. The fixed shaft 6 is coaxially provided with a support groove for the support column 73 to be embedded.

[0054] First, the guide block 3 can be moved until the support column 73 is embedded in the support groove. The support column 73 provides positioning and guidance for the sliding of the fixed shaft 6 toward the fixed groove 71. Then, the guide block 3 is rotated until the rotating block 61 corresponds to the sliding part. Then, the guide block 3 is pushed toward the fixed block 7. After sliding to a certain length, the guide block 3 is rotated so that the rotating block 61 can rotate into the rotating groove 711. The sliding part 722 is restored under the action of the fixed spring 732 and cooperates with the fixed part 721 to restrict the fixed shaft 6 from sliding out of the fixed groove 71. The length of the rotating groove 711 is slightly greater than the thickness of the rotating block 61 to facilitate the installation of the fixed shaft 6. The support column 73 provides support for the fixed shaft 6 under the action of the fixed spring 732, so that the fixed shaft 6 can slide down to the rotating block 61 and fit with the fixed ring 72 under the push of the support column 73. During the rotation of the guide block 3, the guide block 3 is less likely to slide relative to the linkage plate 2, which improves the stability of the guide block 3 installed on the linkage plate 2.

[0055] Reference Figure 8 Furthermore, a ball bearing 611 that is rotatably connected to the rotating plate can be provided on the end face of the rotating plate facing the fixed ring 72. During the rotation of the guide block 3, the ball bearing 611 is in contact with the end face of the fixed ring 72, which reduces the friction between the guide block 3 and the fixed ring 72 and improves the stability of the rotation of the guide block 3. An operating groove communicating with the support groove is provided on the fixed shaft 6. The end of the operating groove away from the support groove extends to the outside of the fixed shaft 6. After the operating rod that cooperates with the operating groove is inserted into the operating groove, the support column 73 can be controlled to slide toward the fixed spring 732, so that the sliding part slides to the point where the rotating plate can rotate out of the rotating groove 711, which facilitates the separation of the guide block 3 from the linkage plate 2.

[0056] The implementation principle of the vehicle lock locking structure in this application embodiment is as follows: the rotation of the locking plate 4 is controlled by the sliding of the central control plate 181. When the central control plate 181 drives the locking plate 4 to rotate until the limit baffle 41 and the limit pin 33 are separated, the vehicle lock is in normal state. The end of the guide block 3 away from the linkage plate 2 is in contact with the side wall of the reinforcing plate 17. When the linkage plate 2 rotates under the action of the outward opening plate 15 and the inward opening push plate 16, the guide block 3 can move with the linkage plate 2 and rotate relative to the linkage plate 2, so that the guide block 3 slides along the side wall of the reinforcing plate 17. The rotation of the guide block 3 relative to the linkage plate 2 can drive the positioning pin 112 to slide along the positioning groove 13, thereby releasing the engagement between the stop pawl 11 and the stop wheel 12.

[0057] When the central control plate 181 drives the locking plate 4 to rotate until the limiting baffle 41 and the limiting pin 33 are engaged, and the guide block 3 rotates to separate from the positioning pin 112 under the cooperation of the limiting baffle 41 and the limiting pin 33, the vehicle lock is in the locked state. When the linkage plate 2 rotates under the action of the outward opening linkage plate 15 and the inward opening push plate 16, the guide block 3 can move with the linkage plate 2 and rotate relative to the linkage plate 2. However, since the guide block 3 has rotated to the state of being separated from the positioning pin 112, the rotation of the guide block 3 does not easily drive the positioning pin 112 to slide along the positioning groove 13, and the stop pawl 11 and the stop wheel 12 remain engaged. In addition, under the action of the limiting baffle 41, the limiting pin 33 can only move around the rotation axis of the stopping pawl 11.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
