[0002] Vehicles and other transportation vehicles are usually equipped with various door structures, which are used to cover the passenger compartment, engine compartment, trunk and other cabin spaces as needed to play a corresponding role of isolation and protection. The door structure is generally equipped with a lock body. When the door structure is closed, the lock body on the door structure and the lock buckle on the vehicle body can be fastened to achieve the locking of the door structure, so that the door structure can be stably kept in a closed state.

[0003] However, after some vehicles have been used for a period of time, the lock body on the door structure and the lock buckle on the vehicle body begin to shift relative to each other, and the lock body and the lock buckle cannot be properly engaged with each other, which makes it difficult for the door structure to close and open smoothly, thereby reducing the locking reliability of the door structure and causing a poor user experience.

[0011] Optionally, the top of the buffer block has a main guide surface, which is inclined upward along the closing direction of the door body, and the higher side of the main guide surface is connected to the limit surface; the main guide surface is used to abut against the lock body during the closing process of the door body to prevent the lock body from moving above the limit surface.

[0012] Optionally, the top of the buffer block has an auxiliary guide surface, which is arranged to be inclined downward along the closing direction of the door body; the higher side of the main guide surface is connected to the first side portion of the limiting surface, and the higher side of the auxiliary guide surface is connected to the second side portion of the limiting surface, and the first side portion and the second side portion are arranged opposite to each other.

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0042] At present, after some vehicles have been used for a period of time, the lock body on the door structure and the lock buckle on the vehicle body begin to have a relative position offset problem, and the lock body and the lock buckle cannot be properly engaged with each other, which makes it difficult for the door structure to close and open smoothly, thereby reducing the locking reliability of the door structure and causing a poor user experience.

[0043] After studying and analyzing vehicles with relative position offset problems between the lock body and the lock buckle, the researchers of this application found that the door structure is hinged to the vehicle body, and the door structure of this part of the vehicle has produced obvious sagging under the combined action of the door's own gravity and external forces. The sagging of the door structure causes the lock body and the lock buckle to have relative displacement in the direction of gravity, which makes it impossible for the lock body and the lock buckle to engage with each other normally.

[0044] In order to solve the above problems, the present application proposes a vehicle door lock structure, which can support and limit the vehicle door structure in a closed state in the direction of gravity, thereby preventing the vehicle door structure from sagging under the combined action of its own gravity and external force, causing the lock body and the lock to fail to engage normally.

[0045] See also Figures 1 to 12 In one embodiment of the present application, the door lock structure includes a lock base plate 1 and a buffer block 2; a lock ring 11 is provided on the lock base plate 1, and the lock base plate 1 is used to be installed on the vehicle body 4; when the door body 5 is closed, the lock ring 11 is used to be buckled with the lock body 3 installed on the door body 5; the buffer block 2 covers the surface of the lock base plate 1, and the buffer block 2 is provided with an avoidance through hole 21, and the lock ring 11 is passed through the avoidance through hole 21; the top of the buffer block 2 has a limiting surface 22; when the lock ring 11 is buckled with the lock body 3, the limiting surface 22 is used to abut against the lock body 3 to buffer and support the lock body 3 in the direction of gravity.

[0046] In this embodiment, the door body 5 may refer to a door structure used to cover the passenger compartment, engine compartment, trunk, etc. on a vehicle or other means of transportation, and is not limited here. The lock base plate 1 may be installed at a corresponding position on the vehicle body 4 by locking, riveting, welding, snap connection, etc. The lock ring 11 may enclose the upper side of the lock base plate 1 to form a buckling space; the lock body 3 may be Figure 1 The caliper-like structure shown in the figure has a movable lock tongue 32 disposed between the two clamp arms 31 of the lock body 3; when the door body 5 is closed, as shown in the figure, Fig.11 As shown, the locking ring 11 will be inserted between the two clamp arms 31 of the lock body 3, and the movable locking tongue 32 of the lock body 3 will pass through the locking ring 11 and be engaged in the snap-fitting space enclosed by the locking ring 11, so that the lock body 3 and the locking ring 11 are engaged with each other, thereby realizing the snap-fitting cooperation between the locking ring 11 and the lock body 3.

[0047] The buffer block 2 can be made of any material with elastic deformation ability; the buffer block 2 can be fixed to the upper side of the lock base plate 1 by locking, clamping, pressing, interference fit between concave and convex structures, or snap fit, and completely cover the lock base plate 1, so that the contact area between the buffer block 2 and the lock body 3 can be increased, ensuring that the limiting surface 22 on the top of the buffer block 2 can be stably abutted against the lock body 3, and the buffer block 2 can be used to form a certain protective effect on the lock base plate 1. Since the buffer block 2 covers the upper side of the lock base plate 1, it is necessary to open an avoidance hole 21 on the buffer block 2 so that the lock ring 11 can pass through the avoidance hole 21 and protrude from the limiting surface 22 on the top of the buffer block 2. During the closing process of the door body 5, if Fig.11As shown, the lock body 3 moves with the door body 5 to the top of the buffer block 2 and is buckled with the lock ring 11. At this time, the limiting surface 22 on the top of the buffer block 2 can form a buffering and supporting effect on the lock body 3 above, and then can form a buffering and supporting effect on the door body 5 in the direction of gravity. This is equivalent to providing an additional fulcrum for the door body 5 outside the hinge structure between the door body 5 and the vehicle body 4, so that the door body 5 is not easy to sag under the combined effect of its own gravity and external force, avoiding the problem of position offset between the lock body 3 and the lock ring 11 in the direction of gravity, ensuring that the lock body 3 and the lock ring 11 can be buckled and matched normally, and the door body 5 can be closed and opened smoothly, thereby improving the locking reliability of the door body 5 and improving the user experience.

[0048] In addition, through the connection and cooperation between the buffer block 2 and the lock base plate 1, the buffer block 2 and the lock base plate 1 can be integrated into an integral structural component. There is no need to separately set a buffer component outside the lock structure, and there is no need to arrange a corresponding installation structure for the separately set buffer component. This can effectively reduce the number of parts of the whole vehicle, thereby reducing the weight of the whole vehicle, reducing the cost of the whole vehicle, and improving the integration of vehicle parts, which is conducive to the development of vehicles towards integration and integration.

[0049] Optionally, refer to Figures 1 to 4 At least one limiting rib 23 is provided at the bottom of the buffer block 2 , and the limiting rib 23 is used to abut and cooperate with the edge side wall of the lock bottom plate 1 .

[0050] Specifically, the structure and orientation of the limiting rib 23 can be arranged to fit the contour of the locking base plate 1, for example, Figure 1 and Figure 3 In the specific embodiment shown, two limiting ribs 23 are provided. Based on the elastic deformation capability of the buffer block 2, the two limiting ribs 23 can be respectively tightly fitted with the two opposite edge side walls of the lock bottom plate 1 through a certain degree of elastic deformation to play a limiting role. The abutment and cooperation between the limiting ribs 23 and the edge side walls of the lock bottom plate 1 can avoid relative slippage and movement between the buffer block 2 and the lock bottom plate 1, thereby improving the connection stability between the buffer block 2 and the lock bottom plate 1.

[0051] Optionally, refer to Figures 1 to 4 At least one protruding structure 12 is provided on the top of the lock base plate 1, and at least one matching groove (not shown in the figure) is provided on the bottom of the buffer block 2; the protruding structures 12 are snap-fitted into the matching grooves one by one.

[0052] Specifically, the protruding structure 12 may be as follows Figure 2The flange structure is provided on the side wall of the edge of the lock bottom plate 1, and the flange structure is easy to be integrally formed when processing the lock bottom plate 1; the number and arrangement of the protruding structures 12 can be set according to actual needs, for example, Figure 2 As shown, four protruding structures 12 are arranged and evenly distributed at the corners of the lock bottom plate 1 to ensure the stability of the engagement between the protruding structures 12 and the matching grooves. The size of the matching grooves can be set to be slightly smaller than the size of the protruding structures 12, so that the elastic deformation ability of the buffer block 2 can be used to make the protruding structures 12 tightly engage with the corresponding matching grooves, forming a good limiting effect, thereby realizing the connection and fixation between the buffer block 2 and the lock bottom plate 1 in a convenient way.

[0053] Optionally, refer to Figures 1 to 4 The protruding structure 12 is extended from bottom to top, and the side wall of the protruding structure 12 is provided with a horizontally extending buckle portion 121, and the buckle portion 121 is used to buckle in the matching groove.

[0054] Specifically, when the protruding structure 12 is as Figure 2 When the arrangement is extended from bottom to top as shown, by providing the horizontally extending reverse buckle portion 121, a bite effect can be formed on the matching groove in the horizontal direction, so as to prevent the buffer block 2 from moving upward and detaching from the protruding structure 12 under the condition of vibration, etc., thereby reducing the probability of relative slippage and movement between the buffer block 2 and the lock bottom plate 1, and further improving the connection stability between the buffer block 2 and the lock bottom plate 1. Among them, the number and distribution position of the reverse buckle portion 121 can be flexibly set according to actual needs, and are not limited here.

[0055] Preferably, a corresponding recessed portion (not shown in the figure) can be provided in the mating groove corresponding to the reverse snap portion 121, and the recessed portion also extends in the horizontal direction. In this way, the connection stability between the buffer block 2 and the lock base plate 1 can be further improved through the snap-fit ​​cooperation between the reverse snap portion 121 and the recessed portion.

[0056] Optionally, refer to Figure 1 , Figure 4 , Figure 5 to Figure 12 The top of the buffer block 2 has a main guide surface 24, which is inclined upward along the closing direction of the door body 5, and the higher side of the main guide surface 24 is connected to the limiting surface 22; the main guide surface 24 is used to abut against the lock body 3 during the closing process of the door body 5 to prevent the lock body 3 from moving above the limiting surface 22.

[0057] Specifically, Figure 1 Taking the XYZ coordinate system shown in the figure as an example, the X-axis and the Y-axis are arranged horizontally, the Z-axis is arranged vertically, and the closing direction of the door body 5 is the horizontal direction located on the XY plane; the main guide surface 24 is arranged to be inclined along the closing direction of the door body 5 and the positive direction of the Z-axis. Figures 5 to 8As shown, when the door body 5 is open, the side of the main guide surface 24 closer to the lock body 3 is the lower side, and the side of the main guide surface 24 farther from the lock body 3 is the higher side and is connected to the limiting surface 22. The limiting surface 22 should be higher than the lowest point of the lock body 3, and the lower side of the main guide surface 24 should be lower than the lowest point of the lock body 3. Based on the above settings, refer to Figures 9 to 12 During the closing process of the door body 5, the lower part of the lock body 3 will first contact the main guide surface 24; as the closing action of the door body 5 continues, the inclined main guide surface 24 will generate an elastic force on the lock body 3 moving with the door body 5, and the elastic force will gradually increase with the closing of the door body 5 and hinder the movement of the lock body 3, thereby generating a certain buffering effect on the closing action of the door body 5, preventing the door body 5 from causing impact damage to the lock body 3 and the lock buckle ring 11 due to excessive closing force; in addition, the main guide surface 24 can form a certain guiding effect on the lock body 3, so that the lock body 3 It can gradually transition along the main guide surface 24 and finally move to above the limiting surface 22. During the movement of the lock body 3, the elastic force of the buffer block 2 on the lock body 3 along the positive direction of the Z axis gradually increases. When the lock body 3 moves to above the limiting surface 22, the elastic force of the buffer block 2 on the lock body 3 along the positive direction of the Z axis reaches the maximum. This can avoid the excessive resistance of the buffer block 2 on the lock body 3 due to the limiting surface 22 being set too high, making it difficult for the lock body 3 to reach above the limiting surface 22, and can also avoid the inability to form effective support on the Z axis for the moved lock body 3 due to the limiting surface 22 being set too low.

[0058] Optionally, refer to Figure 1 , Figure 4 , Figure 5 to Figure 12 The top of the buffer block 2 has an auxiliary guide surface 25, which is arranged to be inclined downward along the closing direction of the door body 5; the higher side of the main guide surface 24 is connected to the first side portion of the limiting surface 22, and the higher side of the auxiliary guide surface 25 is connected to the second side portion of the limiting surface 22, and the first side portion and the second side portion are arranged opposite to each other.

[0059] Specifically, Figures 5 to 8 As shown, when the door body 5 is opened, the main guide surface 24 is located on the side of the limiting surface 22 close to the lock body 3, and the auxiliary guide surface 25 is located on the side of the limiting surface 22 away from the lock body 3. Figures 9 to 12By setting the auxiliary guide surface 25, on the one hand, the area of ​​the limiting surface 22 can be reduced to avoid excessive obstruction to the lock body 3 due to the excessive coverage area of ​​the limiting surface 22, thereby causing the door body 5 to close unsmoothly; on the other hand, the auxiliary guide surface 25 can be symmetrically arranged with the main guide surface 24 relative to the limiting surface 22. When the buffer block 2 is installed in the opposite direction, the auxiliary guide surface 25 can be used as the main guide surface 24. In this way, the problem of the buffer block 2 being unable to be used normally due to the operator's negligence and the reverse installation can be avoided, thereby improving the fault tolerance; it can be understood that when the buffer block 2 is installed in the opposite direction, when the door body 5 is opened, the auxiliary guide surface 25 becomes the main guide surface 24 close to the lock body 3, and the main guide surface 24 becomes the auxiliary guide surface 25 away from the lock body 3.

[0060] Optionally, refer to Figure 1 , Figure 4 , Figure 5 to Figure 12 The locking base plate 1 is used to move on the vehicle body 4 in a direction parallel to the limiting surface 22, and the locking base plate 1 is used to be locked to the vehicle body 4 through a first threaded fastener (not shown in the figure).

[0061] Specifically, Figure 1 Taking the XYZ coordinate system shown as an example, the X-axis and the Y-axis are arranged horizontally, the Z-axis is arranged vertically, and the limiting surface 22 is parallel to the XY plane; an oblong hole or an oblong arc hole can be arranged at one of the locking base plate 1 and the vehicle body 4, and a threaded hole can be arranged at another of the locking base plate 1 and the vehicle body 4, so that the locking base plate 1 can move along the XY plane within the matching range of the oblong hole / oblong arc hole and the threaded hole; when the locking base plate 1 is moved into position relative to the vehicle body 4, the first threaded fastener can pass through the oblong hole / oblong arc hole and the threaded hole in sequence and lock the locking base plate 1 to the vehicle body 4. Among them, the first threaded fastener can be a fastener such as a bolt, a screw, a stud, etc., which is not limited here. Since the buffer block 2 covers the surface of the locking base plate 1, a corresponding receiving through hole 26 can be opened on the buffer block 2 to avoid the buffer block 2 from obstructing the first threaded fastener, so as to facilitate the first threaded fastener to pass through the receiving through hole 26 and complete the locking of the locking base plate 1.

[0062] Based on the above arrangement, the position of the lock base plate 1 in the XY plane can be adjusted so that the lock ring 11 can be more accurately fastened to the lock body 3, thereby improving the matching accuracy between the lock ring 11 and the lock body 3.

[0063] Optionally, refer to Figure 1 , Figure 4 , Figure 5 to Figure 12The side of the lock bottom plate 1 that is used to fit with the vehicle body 4 is provided with a protective layer (not shown in the figure). The protective layer can provide protection for the mounting surface of the lock bottom plate 1 to prevent the mounting surface of the lock bottom plate 1 from being damaged due to scratches or collisions during the process of adjusting the mounting position. The protective layer can be a steel gasket or a plastic protective shell.

[0064] Optionally, refer to Figure 1 , Figure 4 , Figure 5 to Figure 12 The buffer block 2 is made of rubber material. The rubber material has good elasticity and can quickly restore to its original state when subjected to pressure or impact. In this way, the buffer block 2 can effectively absorb and disperse the impact force generated when the door body 5 is closed while forming a stable support for the lock body 3, and can protect the lock body 3, the lock ring 11 and other components, and can reduce the noise generated by the door body 5 during the closing process.

[0065] See also Figure 1 , Figure 5 to Figure 13 The present application also proposes a vehicle door assembly, comprising a vehicle door body 5, a lock body 3 and a vehicle door lock structure in any of the above-mentioned embodiments; the lock body 3 is installed on the vehicle door body 5, and the vehicle door body 5 is used to be hinged on the vehicle body 4; when the vehicle door body 5 is closed, the lock body 3 is buckled with the lock ring 11.

[0066] In this embodiment, the door assembly refers to a complete door structure used to cover the cabin, engine compartment, trunk and other cabin spaces on vehicles such as cars, trucks, aircraft (including flying cars), for example Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 , Fig.13 The double-opening tailgate at the rear of the car shown is not limited here.

[0067] Since the vehicle door assembly adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, that is, a buffer block 2 is correspondingly arranged on the lock base plate 1, and during the closing process of the vehicle door body 5, the lock body 3 moves with the vehicle door body 5 to the top of the buffer block 2 and is buckled and matched with the lock ring 11 on the lock base plate 1. At this time, the limiting surface 22 on the top of the buffer block 2 can form a buffering and supporting effect on the upper lock body 3, and then can form a buffering and supporting effect on the vehicle door body 5 in the direction of gravity. This is equivalent to providing an additional fulcrum for the vehicle door body 5 in addition to the hinged structure between the vehicle door body 5 and the vehicle body 4, so that the vehicle door body 5 is not easy to sag under the combined action of its own gravity and external force, avoiding the problem of position offset between the lock body 3 and the lock ring 11 in the direction of gravity, and ensuring that the lock body 3 and the lock ring 11 can be properly With the regular buckling fit, the door body 5 can be closed and opened smoothly, thereby improving the locking reliability of the door body 5 and improving the user experience; and because the buffer block 2 completely covers the lock base plate 1, the contact area between the buffer block 2 and the lock body 3 can be increased, ensuring that the limiting surface 22 on the top of the buffer block 2 can stably abut against the lock body 3, and the buffer block 2 can be used to form a certain protective effect on the lock base plate 1; in addition, through the connection and fit between the buffer block 2 and the lock base plate 1, the buffer block 2 and the lock base plate 1 can be integrated into an integral structural member, without the need to separately set a buffer component outside the lock structure, and even more without arranging a corresponding installation structure for the separately set buffer component, thereby effectively reducing the number of parts of the whole vehicle, thereby reducing the weight of the whole vehicle, reducing the cost of the whole vehicle, and improving the integration of vehicle parts, which is conducive to the development of vehicles towards integration and integration.

[0068] Optionally, refer to Figure 1 , Figure 5 to Figure 12 The lock body 3 is used to move on the door body 5 in a direction perpendicular to the limiting surface 22, and the lock body 3 is used to be locked to the door body 5 through a second threaded fastener (not shown in the figure).

[0069] Specifically, Figure 1 Taking the XYZ coordinate system shown as an example, the X-axis and the Y-axis are arranged horizontally, the Z-axis is arranged vertically, the limiting surface 22 is parallel to the XY plane, and the Z-axis is perpendicular to the limiting surface 22; an oblong hole can be arranged at one of the lock body 3 and the door body 5, and a threaded hole can be arranged at another of the lock body 3 and the door body 5, so that the lock body 3 can move along the Z-axis within the matching range of the oblong hole and the threaded hole; when the lock body 3 is moved into position relative to the door body 5, the second threaded fastener can pass through the oblong hole and the threaded hole in sequence and lock the lock body 3 to the door body 5. Among them, the second threaded fastener can be a fastener such as a bolt, a screw, a stud, etc., which is not limited here.

[0070] Based on the above settings, the position of the lock body 3 on the Z-axis can be adjusted, so that the lock body 3 can be more accurately buckled with the locking ring 11, thereby improving the matching accuracy between the lock body 3 and the locking ring 11; in addition, the vertical distance between the lock body 3 and the buffer block 2 can also be adjusted to the optimal state, thereby ensuring that the buffer block 2 can form an effective supporting and limiting effect on the lock body 3.

[0071] See also Figure 1 , Figure 5 to Figure 13 The present application also proposes a vehicle, comprising a door assembly in any of the above embodiments.

[0072] In this embodiment, the vehicle includes but is not limited to cars, trucks and aircraft (including flying cars); the door assembly refers to a complete door structure used to cover the cabin, engine compartment, trunk and other cabin spaces on the vehicle, for example Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 , Fig.13 The double-opening tailgate at the rear of the car shown is not limited here.

[0073] Since the vehicle adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, that is, a buffer block 2 is correspondingly arranged on the lock base plate 1, and during the closing process of the door body 5, the lock body 3 moves with the door body 5 to the top of the buffer block 2 and is buckled with the lock ring 11 on the lock base plate 1. At this time, the limiting surface 22 on the top of the buffer block 2 can form a supporting effect on the upper lock body 3, and then can form a supporting effect on the door body 5 in the direction of gravity, which is equivalent to providing an additional fulcrum for the door body 5 in addition to the hinged structure between the door body 5 and the vehicle body 4, so that the door body 5 is not easy to sag under the combined action of its own gravity and external force, avoiding the problem of position offset between the lock body 3 and the lock ring 11 in the direction of gravity, and ensuring that the lock body 3 and the lock ring 11 can be buckled normally With the cooperation, the vehicle door body 5 can be closed and opened smoothly, thereby improving the locking reliability of the vehicle door body 5 and improving the user experience; and because the buffer block 2 completely covers the lock base plate 1, the contact area between the buffer block 2 and the lock body 3 can be increased, ensuring that the limiting surface 22 on the top of the buffer block 2 can stably abut against the lock body 3, and the buffer block 2 can be used to form a certain protective effect on the lock base plate 1; in addition, through the connection and cooperation between the buffer block 2 and the lock base plate 1, the buffer block 2 and the lock base plate 1 can be integrated into an integral structural member, without the need to separately set a buffer component outside the lock structure, and there is no need to arrange a corresponding installation structure for the separately set buffer component, thereby effectively reducing the number of parts of the whole vehicle, thereby reducing the weight of the whole vehicle, reducing the cost of the whole vehicle, and improving the integration of vehicle parts, which is conducive to the development of vehicles towards integration and integration.
