Technical Field
[0001] The present application relates to the technical field of transportation, and particularly relates to a door lock structure, a door assembly and a vehicle. Background Art
[0002] Various door structures are usually provided on vehicles and other means of transportation. The door structure is used to cover the cabin spaces such as the passenger compartment, the engine compartment, the trunk, etc. as needed, so as to play corresponding roles of isolation, protection, etc. A lock body is generally provided on the door structure. When the door structure is closed, the locking of the door structure can be realized through the buckling cooperation between the lock body on the door structure and the lock buckle on the vehicle body, so that the door structure can stably maintain the closed state.
[0003] However, after some means of transportation are used for a period of time, the problem of relative position offset begins to occur between the lock body on the door structure and the lock buckle on the vehicle body. The lock body and the lock buckle cannot be normally buckled and matched, resulting in difficulty in smoothly closing and opening the door structure, thereby reducing the locking reliability of the door structure and poor user experience. Summary of the Utility Model
[0004] The main purpose of the present application is to propose a door lock structure, aiming to solve the problem that the relative position between the lock body on the door structure and the lock buckle on the vehicle body is prone to offset, so that the lock body and the lock buckle can be normally buckled and matched, thereby improving the locking reliability of the door structure.

[0006] A lock buckle bottom plate, on which a lock buckle ring is provided, and the lock buckle bottom plate is used for being installed on the vehicle body; when the door body is closed, the lock buckle ring is used for buckling with the lock body installed on the door body;
[0007] A buffer block, which is connected to the lock buckle ring, and the top of the buffer block has a limiting surface; when the lock buckle ring is buckled with the lock body, the limiting surface is used for abutting against the lock body to buffer and support the lock body in the gravity direction.
[0008] Optionally, at least one convex structure is provided on the lock buckle bottom plate; the buffer block is snap-fitted on the convex structure, and the buffer block is spaced from the lock buckle ring.
[0009] Optionally, at least one mating groove is provided at the bottom of the buffer block, and the convex structures are respectively snap-fitted in the mating grooves.
[0010] Optionally, the convex structure extends upward, and a horizontally extending buckling portion is provided on the side wall of the convex structure, and the buckling portion is used for buckling in the matching groove.
[0011] Optionally, the convex structure is provided as a flanging structure integrally formed on the edge of the latch base plate.
[0012] Optionally, the top of the buffer block has a guiding surface, the guiding surface is inclined upward along the closing direction of the vehicle door body, and the higher side of the guiding surface is butted against the limiting surface; the guiding surface is used for abutting against the lock body during the closing process of the vehicle door body to block the lock body from moving above the limiting surface.
[0013] Optionally, the latch base plate is used for moving on the vehicle body in a direction parallel to the limiting surface, and the latch base plate is used for being locked to the vehicle body through a first threaded fastener.
[0014] Optionally, a protective layer is provided on the side of the latch base plate for fitting with the vehicle body;
[0015] Optionally, the buffer block is made of rubber material.
[0016] The present application also provides a vehicle door assembly, including a vehicle door body, a lock body, and the vehicle door latch structure as described above; the lock body is installed on the vehicle door body, and the vehicle door body is used for being hinged to the vehicle body; when the vehicle door body is closed, the lock body is buckled with the latch ring.
[0017] Optionally, the lock body is used for moving on the vehicle door body in a direction perpendicular to the limiting surface, and the lock body is used for being locked to the vehicle door body through a second threaded fastener.
[0018] The present application also provides a vehicle, including the vehicle door assembly as described above.
[0019] In the technical solution of the present application, a buffer block is correspondingly arranged on the latch base plate. During the closing process of the vehicle door body, the lock body moves above the buffer block along with the vehicle door body and is buckled and matched with the latch ring on the latch base plate. At this time, the limiting surface at the top of the buffer block can form a supporting effect on the lock body above, and further can form a supporting effect on the vehicle door body in the direction of gravity. In this way, it is equivalent to providing an additional fulcrum for the vehicle door body outside the hinge structure between the vehicle door body and the vehicle body, making it difficult for the vehicle door body to sag under the combined action of its own gravity and external forces, avoiding the problem of position offset between the lock body and the latch ring in the direction of gravity, ensuring that the lock body and the latch ring can be normally buckled and matched, and the vehicle door body can be smoothly closed and opened, thereby improving the locking reliability of the vehicle door body and improving the user experience.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.
[0040] At present, after some means of transportation have been used for a period of time, a problem of relative position deviation between the lock body on the door structure and the lock catch on the vehicle body begins to occur. The lock body and the lock catch cannot be normally buckled and matched, resulting in difficulty in smoothly closing and opening the door structure, thereby reducing the locking reliability of the door structure and poor user experience.
[0041] After the R & D personnel of this application studied and analyzed vehicles with relative position offset problems between the lock body and the lock catch, it was found that the door structure is hinged to the vehicle body, and the door structure of this part of the vehicle has sagged significantly under the combined action of its own gravity and external forces. The sagging of the door structure causes relative displacement between the lock body and the lock catch in the direction of gravity, thus resulting in the inability of the lock body and the lock catch to be properly latched and matched.
[0042] To solve the above problems, this application proposes a door lock catch structure that can support and limit the door structure in the closed state in the direction of gravity, preventing the door structure from sagging under the combined action of its own gravity and external forces, which may lead to the inability of the lock body and the lock catch to be properly latched and matched.
[0043] Please refer to Figures 1 to 10 , in an embodiment of this application, the door lock catch structure includes a lock catch base plate 1 and a buffer block 2; the lock catch base plate 1 is provided with a lock catch ring 11, and the lock catch base plate 1 is used to be installed on the vehicle body 4; when the door body 5 is closed, the lock catch ring 11 is used to be latched with the lock body 3 installed on the door body 5; the buffer block 2 is connected to the lock catch ring 11, and the top of the buffer block 2 has a limiting surface 21; when the lock catch ring 11 is latched with the lock body 3, the limiting surface 21 is used to abut against the lock body 3 to buffer and support the lock body 3 in the direction of gravity.
[0044] In this embodiment, the door body 5 can refer to the door structure used to cover the cabin space such as the passenger compartment, engine compartment, and trunk of vehicles and other means of transportation, which is not limited here. The lock catch base plate 1 can be installed at the corresponding position on the vehicle body 4 by means of locking, riveting, welding, snap connection, etc. The lock catch ring 11 can enclose a latching space on the upper side of the lock catch base plate 1; the lock body 3 can be in the Figure 1 shown caliper-like structure, and there is a movable lock tongue 32 between the two clamping arms 31 of the lock body 3; after the door body 5 is closed, as Figure 9 shown, the lock catch ring 11 will be inserted between the two clamping arms 31 of the lock body 3, and the movable lock tongue 32 of the lock body 3 will pass through the lock catch ring 11 and be latched in the latching space enclosed by the lock catch ring 11, so that the lock body 3 and the lock catch ring 11 are engaged with each other, thus realizing the latching and matching between the lock catch ring 11 and the lock body 3.
[0045] The buffer block 2 can be made of any material with elastic deformation ability. Specifically, the buffer block 2 can be set in the block shape as shown in Figure 1 and Figure 2 shown. The number of buffer blocks 2 can be set as shown in Figure 1 and Figure 2One or more of the shown are fixed to the buffer bottom plate 1 by means such as snap connection, nesting, attachment, locking, etc. After fixation, the buffer block 2 should be located below the lock body 3 in the snap - connected state; the upper side surface of the buffer block 2 can be set as a limiting surface 21, and the part of the lock catch ring 11 for snap - connection and cooperation with the lock body 3 should be higher than the limiting surface 21 to ensure that the lock catch ring 11 can be normally snap - connected with the lock body 3.
[0046] Based on the above settings, during the closing process of the vehicle door body 5, as Figure 9 shown, the lock body 3 moves with the vehicle door body 5 above the buffer block 2 and is snap - connected with the lock catch ring 11. At this time, the limiting surface 21 at the top of the buffer block 2 can support the upper lock body 3, and thus can form a buffering and supporting effect on the vehicle door body 5 in the direction of gravity. In this way, it is equivalent to providing an additional fulcrum for the vehicle door body 5 outside the hinge structure between the vehicle door body 5 and the vehicle body 4, making the vehicle door body 5 not easily sag under the combined action of its own gravity and external forces, avoiding the problem of position offset between the lock body 3 and the lock catch ring 11 in the direction of gravity, ensuring that the lock body 3 and the lock catch ring 11 can be normally snap - connected, and enabling the vehicle door body 5 to be smoothly closed and opened, thereby improving the locking reliability of the vehicle door body 5 and enhancing the user experience.
[0047] Optionally, referring to Figure 1 , the lock catch bottom plate 1 is provided with at least one convex structure 12; the buffer block 2 is snap - connected to the convex structure 12, and the buffer block 2 and the lock catch ring 11 are arranged at intervals.
[0048] Specifically, the convex structure 12 can be integrally formed on the lock catch bottom plate 1 or connected to the lock catch bottom plate 1. The number and arrangement position of the convex structure 12 can be flexibly set according to the required installation position of the buffer block 2, and no limitation is made here. Through the connection and cooperation between the buffer block 2 and the lock catch bottom plate 1, the buffer block 2 and the lock catch bottom plate 1 can be integrated into a whole structural part, without separately setting a buffer device outside the lock catch structure, and even more without arranging a corresponding installation structure for the separately set buffer device. Thus, it can effectively reduce the number of vehicle parts, and further reduce the weight of the whole vehicle, lower the cost of the whole vehicle, and improve the integration degree of vehicle parts, which is conducive to the development of the vehicle towards the direction of integration and integration. And based on the structural form and connection method of the buffer block 2, the position of the buffer block 2 on the lock catch bottom plate 1 can be flexibly and conveniently adjusted according to needs to meet the actual requirements of the support point, and the coverage range of the buffer block 2 only needs to be limited to the area that the lock body 3 will surely pass through. In this way, the volume of the buffer block 2 can be minimized, and further the material used for the buffer block 2 can be reduced, the material cost can be lowered, and the problem that it is not easy to cause interference due to the excessive shielding area of the buffer block 2 on the lock catch bottom plate 1 and thus it is not convenient to install the lock catch bottom plate 1 on the vehicle body 4 can also be avoided.
[0049] Optionally, referring to Figure 1 andFigure 2 At least one mating groove (not shown in the figure) is provided at the bottom of the buffer block 2, and the protruding structures 12 are respectively snap-fitted into the mating grooves.
[0050] Specifically, the mating groove can be provided on the lower side surface of the buffer block 2, and the size of the mating groove can be slightly smaller than the size of the protruding structure 12. In this way, it is convenient to snap the buffer block 2 onto the protruding structure 12 from top to bottom, and the elastic deformation ability of the buffer block 2 is used to make the mating groove closely adhere to the surface of the protruding structure 12. In this way, the connection and fixation between the buffer block 2 and the latch bottom plate 1 can be conveniently completed, and it is also convenient to disassemble and replace the buffer block 2 later.
[0051] Optionally, referring to Figure 1 and Figure 2 , the protruding structure 12 extends upward from bottom to top, and a horizontally extending anti-locking portion (not shown in the figure) is provided on the side wall of the protruding structure 12, and the anti-locking portion is used for being snap-fitted in the mating groove.
[0052] Specifically, when the protruding structure 12 extends upward from bottom to top at the perspectives shown in Figure 1 and Figure 2 , by setting the horizontally extending anti-locking portion, a biting effect can be formed on the mating groove in the horizontal direction, avoiding the buffer block 2 from moving upward and disengaging from the protruding structure 12 under vibrations and other conditions, thereby reducing the probability of relative sliding and upward movement problems between the buffer block 2 and the latch bottom plate 1, and further improving the connection stability between the buffer block 2 and the latch bottom plate 1. Among them, the number and distribution position of the anti-locking portions can be flexibly set according to actual needs and are not limited here.
[0053] Preferably, corresponding recessed portions (not shown in the figure) can be provided in the mating groove corresponding to the anti-locking portions, and the recessed portions also extend in the horizontal direction. In this way, the connection stability between the buffer block 2 and the latch bottom plate 1 can be further improved through the snap-fitting between the anti-locking portions and the recessed portions.
[0054] Optionally, referring to Figure 1 and Figure 2 , the protruding structure 12 is provided as a flanging structure integrally formed at the edge of the latch bottom plate 1; this flanging structure is easy to be integrally formed by bending and other means during the process of machining the latch bottom plate 1, thereby improving the overall production efficiency of the latch bottom plate 1.
[0055] Optionally, referring to Figures 1 to 10 , the top of the buffer block 2 has a guiding surface 22, and the guiding surface 22 is inclined upward along the closing direction of the vehicle door body 5, and the higher side of the guiding surface 22 is butted against the limiting surface 21; the guiding surface 22 is used for abutting against the lock body 3 during the closing process of the vehicle door body 5 to block the lock body 3 from moving above the limiting surface 21.
[0056] Specifically, taking the Figure 1 shown XYZ coordinate system as an example, the X-axis and Y-axis are horizontally arranged, the Z-axis is vertically arranged, and the closing direction of the door body 5 is the horizontal direction on the XY plane; the guiding surface 22 is located on the upper end surface of the buffer block 2, and the guiding surface 22 is inclined both in the closing direction of the door body 5 and in the positive Z-axis direction. As shown in Figures 3 to 6 , in the state where the door body 5 is open, the side of the guiding surface 22 closer to the lock body 3 is the lower side, and the side of the guiding surface 22 farther from the lock body 3 is the higher side and is docked with the limiting surface 21. The limiting surface 21 should be higher than the lowest point of the lock body 3, and the lower side of the guiding surface 22 should be lower than the lowest point of the lock body 3. Based on the above settings, referring to Figures 7 to 10 , during the closing process of the door body 5, the lower part of the lock body 3 will first contact the guiding surface 22; as the closing action of the door body 5 continues, the inclined guiding surface 22 will generate an elastic force on the lock body 3 moving with the door body 5. This elastic force will gradually increase as the door body 5 closes and hinder the movement of the lock body 3, thereby having a certain buffering effect on the closing action of the door body 5 and avoiding impact damage to the lock body 3 and the lock catch ring 11 due to excessive closing force of the door body 5; in addition, the guiding surface 22 can form a certain guiding effect on the lock body 3, enabling the lock body 3 to gradually transition along the guiding surface 22 and finally move above the limiting surface 21. During the movement of the lock body 3, the elastic force generated by the buffer block 2 on the lock body 3 in the positive Z-axis direction gradually increases. When the lock body 3 moves above the limiting surface 21, the elastic force generated by the buffer block 2 on the lock body 3 in the positive Z-axis direction reaches the maximum. In this way, it can be avoided that due to the overly high setting of the limiting surface 21, the resistance generated by the buffer block 2 on the lock body 3 is too large, making it difficult for the lock body 3 to reach above the limiting surface 21, and it can also be avoided that due to the overly low setting of the limiting surface 21, the lock body 3 that has moved in place cannot be effectively supported in the Z-axis direction.
[0057] Optionally, referring to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 , the lock catch bottom plate 1 is used to move on the vehicle body 4 in a direction parallel to the limiting surface 21, and the lock catch bottom plate 1 is used to be locked to the vehicle body 4 through the first threaded fastener 6.
[0058] Specifically, taking the Figure 1Taking the XYZ coordinate system shown as an example, the X-axis and Y-axis are set horizontally, the Z-axis is set vertically, and the limiting surface 21 is parallel to the XY plane; one of the latch base plate 1 and the vehicle body 4 can be provided with an oblong hole or an oblong arc hole, and the other of the latch base plate 1 and the vehicle body 4 can be provided with a threaded hole, so that the latch base plate 1 can move along the XY plane within the fitting range of the oblong hole / oblong arc hole and the threaded hole; when the latch base plate 1 moves relative to the vehicle body 4 to the in-place position, the first threaded fastener 6 can pass through the oblong hole / oblong arc hole and the threaded hole in sequence and lock and fix the latch base plate 1 to the vehicle body 4. Among them, the first threaded fastener 6 can adopt fasteners such as bolts, screws, studs, etc., which are not limited here.
[0059] Based on the above settings, the position adjustment of the latch base plate 1 on the XY plane can be realized, so that the latch ring 11 can be more accurately buckled with the lock body 3, thereby improving the fitting accuracy between the latch ring 11 and the lock body 3.
[0060] Optionally, referring to Figures 1 to 10 , a protective layer (not shown in the figure) is provided on the side of the latch base plate 1 for fitting with the vehicle body 4. The protective layer can provide protection for the installation surface of the latch base plate 1 to prevent the installation surface of the latch base plate 1 from being damaged due to scraping and collision during the process of adjusting the installation position. Among them, the protective layer can adopt a steel gasket or a plastic protective shell.
[0061] Optionally, referring to Figures 1 to 10 , the buffer block 2 is made of rubber material. The rubber material has good elasticity and can quickly return 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 vehicle door body 5 is closed while forming a stable supporting effect on the lock body 3, can protect the lock body 3, the latch ring 11 and other components, and can reduce the noise generated during the closing process of the vehicle door body 5.
[0062] Please refer to Figures 3 to 11 , this application also proposes a vehicle door assembly, including a vehicle door body 5, a lock body 3 and the vehicle door latch structure in any of the above embodiments; the lock body 3 is installed on the vehicle door body 5, and the vehicle door body 5 is used for being hinged on the vehicle body 4; when the vehicle door body 5 is closed, the lock body 3 is buckled with the latch ring 11.
[0063] In this embodiment, the vehicle door assembly refers to a complete vehicle door structure used for covering a cabin space such as a passenger compartment, an engine compartment, a trunk, etc. on a vehicle such as an automobile, a truck, an aircraft (including a flying car), for example Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 11 the split tailgate at the rear of the vehicle shown, which is not limited here.
[0064] Since the door assembly adopts all the technical solutions of 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. During the closing process of the door body 5, the lock body 3 moves with the door body 5 above 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 21 at the top of the buffer block 2 can support the lock body 3 above, and then can support the door body 5 in the direction of gravity. In this way, it 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 easily sagged under the combined action of its own gravity and external force, avoiding the problem of position deviation 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 normally buckled and matched, and the door body 5 can be smoothly closed and opened, thereby improving the locking reliability of the door body 5 and improving the user experience. 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 a whole structural member, without separately arranging a buffer device outside the lock structure, and there is no need to arrange a corresponding installation structure for the separately arranged buffer device, so that the number of parts of the whole vehicle can be effectively reduced, and then the weight of the whole vehicle can be reduced, the cost of the whole vehicle can be reduced, and the integration degree of vehicle parts can be improved, which is beneficial to the development of the vehicle in the direction of integration and integration. And based on the structural form and connection method of the buffer block 2, the position of the buffer block 2 on the lock base plate 1 can be flexibly and conveniently adjusted as needed to meet the actual requirements of the support point, and the coverage range of the buffer block 2 only needs to be limited to the area that the lock body 3 will necessarily pass through. In this way, the volume of the buffer block 2 can be minimized, and then the material used for the buffer block 2 can be reduced, the material cost can be reduced, and the problem that it is not easy to cause interference due to the excessive shielding area of the buffer block 2 on the lock base plate 1 and thus it is not convenient to install the lock base plate 1 on the vehicle body 4 can be avoided.
[0065] Optionally, referring to Figure 1 、 Figures 3 to 10 Figure, the lock body 3 is used to move on the door body 5 in a direction perpendicular to the limiting surface 21, 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).
[0066] Specifically, taking Figure 1Taking the XYZ coordinate system shown as an example, the X-axis and Y-axis are set horizontally, the Z-axis is set vertically, the limiting surface 21 is parallel to the XY plane, and the Z-axis is perpendicular to the limiting surface 21; an oblong hole can be set at one of the lock body 3 and the vehicle door body 5, and a threaded hole can be set at the other of the lock body 3 and the vehicle door body 5, so that the lock body 3 can move along the Z-axis within the fitting range of the oblong hole and the threaded hole; after the lock body 3 moves relative to the vehicle door body 5 in place, the second threaded fastener can pass through the oblong hole and the threaded hole in sequence and lock and fix the lock body 3 to the vehicle door body 5. Among them, the second threaded fastener can adopt fasteners such as bolts, screws, and studs, which are not limited here.
[0067] Based on the above settings, the position adjustment of the lock body 3 on the Z-axis can be realized, so that the lock body 3 can be more accurately buckled with the buckle ring 11, improving the fitting accuracy between the lock body 3 and the buckle 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, so as to ensure that the buffer block 2 can form an effective supporting and limiting effect on the lock body 3.
[0068] Please refer to Figures 3 to 11 , this application also proposes a vehicle, including the vehicle door assembly in any of the above embodiments.
[0069] In this embodiment, the vehicle includes but is not limited to cars, trucks, and aircraft (including flying cars); the vehicle door assembly refers to the complete vehicle door structure used on the vehicle to cover the cabin spaces such as the passenger compartment, engine compartment, and trunk, such as Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 11 the split tailgate at the rear of the car shown, which is not limited here.
[0070] Since this vehicle adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, that is, a buffer block 2 is correspondingly arranged on the lock buckle bottom plate 1. During the closing process of the vehicle door body 5, the lock body 3 moves with the vehicle door body 5 to above the buffer block 2 and is buckled and fitted with the buckle ring 11 on the lock buckle bottom plate 1. At this time, the limiting surface 21 at the top of the buffer block 2 can form a supporting effect on the lock body 3 above, and further can form a supporting effect on the vehicle door body 5 in the direction of gravity. In this way, it is equivalent to providing an additional fulcrum for the vehicle door body 5 outside the hinge 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 forces, avoiding the problem of position offset between the lock body 3 and the buckle ring 11 in the direction of gravity, ensuring that the lock body 3 and the buckle ring 11 can be normally buckled and fitted, and the vehicle door body 5 can be smoothly closed and opened, thereby improving the locking reliability of the vehicle door body 5 and improving the user experience.
[0071] The above are only exemplary embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the technical concept of the present application by using the content of the specification and drawings of the present application, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
