[0001] The present application relates to the technical field of transportation, and particularly to a door lock buckle structure, a door assembly and a vehicle. Background Art

[0002] Various door structures are usually provided on vehicles and other vehicles. The door structure is used to cover the cabin spaces such as the passenger compartment, the engine compartment, and the trunk according to needs, so as to play corresponding isolation, protection and other roles. A lock body is generally provided on the door structure. When the door structure is closed, the door structure can be locked by the snap-fit 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 vehicles have been used for a period of time, the relative position between the lock body on the door structure and the lock buckle on the vehicle body begins to shift. The lock body and the lock buckle cannot be normally snap-fitted, 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

[0011] Optionally, the top of the buffer block has an auxiliary guiding surface which is inclined downward along the closing direction of the vehicle door body; the higher side of the main guiding surface is butted against the first side portion of the limiting surface, and the higher side of the auxiliary guiding surface is butted against the second side portion of the limiting surface, and the first side portion and the second side portion are oppositely arranged.

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0038] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present application, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0039] In addition, if there are descriptions such as "first" and "second" involved in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. 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 begins to occur between the lock body on the door structure and the lock catch on the vehicle body. The lock body and the lock catch cannot be normally engaged 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 research and analysis of the means of transportation with the problem of relative position deviation between the lock body and the lock catch by the R & D personnel of the present application, it is found that the door structure is hinged to the vehicle body, and the door structure of this part of the means of transportation has sagged significantly under the combined action of the self-gravity of the door and external forces. The sagging of the door structure causes a 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 normally engaged and matched.

[0042] To solve the above problems, the present application proposes a door lock catch structure, which 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, resulting in the inability of the lock body and the lock catch to be normally engaged and matched.

[0043] Please refer to Figures 1 to 11 , in an embodiment of the present application, the door lock buckle structure includes a buckle bottom plate 1 and a buffer block 2; the buckle bottom plate 1 is provided with a buckle ring 11, and the buckle bottom plate 1 is installed on the vehicle body 4; when the door body 5 is closed, the buckle ring 11 is buckled with the lock body 3 installed on the door body 5; the buffer block 2 is in a closed ring shape and is arranged around the buckle ring 11, the buffer block 2 is provided with a buckling rib 21, and the buckling rib 21 is buckled on the buckle bottom plate 1; the top of the buffer block 2 has a limiting surface 22; when the buckle 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.

[0044] In this embodiment, the door body 5 may refer to a door structure used to cover a cabin space such as a passenger compartment, an engine compartment, a trunk, etc. on a vehicle or other means of transportation, and is not limited herein. The buckle bottom plate 1 can be installed at the corresponding position on the vehicle body 4 by means of locking, riveting, welding, snap connection, etc. The buckle ring 11 can form a buckling space on the upper side surface of the buckle bottom plate 1; the lock body 3 can be in the shape of Figure 1 the caliper-like structure shown, and there is a movable lock tongue 32 between the two clamping arms 31 of the lock body 3; when the door body 5 is closed, as Figure 10 shown, the buckle 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 buckle ring 11 and be clamped in the buckling space formed by the enclosure of the buckle ring 11, so that the lock body 3 and the buckle ring 11 are engaged with each other, thus realizing the buckling cooperation between the buckle ring 11 and the lock body 3.

[0045] The buffer block 2 can be made of any material with elastic deformation ability. The buffer block 2 in the shape of a closed ring can be specifically set as a rectangular ring, a circular ring or other irregular rings as Figures 1 to 3 shown, and is not limited herein; the buffer block 2 can be sleeved on the buckle ring 11 from top to bottom to play a certain limiting role on the buffer block 2 through the buckle ring 11, and then the buckling rib 21 is buckled on the buckle bottom plate 1, so that the buffer block 2 can be fixed on the upper side surface of the buckle bottom plate 1. Among them, the buckling rib 21 can be arranged at the bottom of the buffer block 2 and buckled on the edge side wall of the buckle bottom plate 1. More specifically, two buckling ribs 21 can be set as Figure 2 and Figure 3 shown, and the two buckling ribs 21 are respectively buckled on the opposite side walls of the buckle bottom plate 1; in addition, the buckling rib 21 can also be buckled on the concave-convex structure on the surface of the buckle bottom plate 1 that is adapted thereto, and is not limited herein. The upper end face of the buffer block 2 can form the limiting surface 22, and the part of the buckle ring 11 used for buckling cooperation with the lock body 3 should be higher than the limiting surface 22 to ensure that the buckle ring 11 can be normally buckled with the lock body 3.

[0046] Based on the above settings, during the closing process of the vehicle door body 5, as Figure 10 shown, the lock body 3 moves with the vehicle door body 5 above the buffer block 2 and is buckled and cooperated with the lock catch ring 11. At this time, the limiting surface 22 at the top of the buffer block 2 can buffer and support the upper lock body 3, and further buffer and support the vehicle door body 5 in the gravity direction. 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 easily sagged 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 gravity direction, ensuring that the lock body 3 and the lock catch ring 11 can be normally buckled and cooperated, 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.

[0047] In addition, 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 buffer devices outside the lock catch structure, and there is no need to arrange corresponding installation structures for the separately set buffer devices, so as to effectively reduce the number of vehicle parts, and further reduce the weight of the whole vehicle, reduce the cost of the whole vehicle, and improve the integration degree of vehicle parts, which is beneficial to the development of the vehicle towards integration and integration. And based on the closed-ring structure setting form of the buffer block 2, the coverage range of the buffer block 2 can be limited to the area that will inevitably contact the lock body 3 around the lock catch ring 11, without covering the entire lock catch bottom plate 1 with the buffer block 2. In this way, the material used for the buffer block 2 can be reduced, the material cost can be reduced, and the problem that it is easy to cause interference due to the excessive shielding area of the buffer block 2 on the lock catch bottom plate 1 and it is not convenient to install the lock catch bottom plate 1 on the vehicle body 4 can be avoided.

[0048] Optionally, referring to Figures 1 to 3 , at least one convex structure (not shown in the figure) is provided on the top of the lock catch bottom plate 1, and at least one mating groove (not shown in the figure) is provided on the bottom of the buffer block 2; the convex structures are respectively and correspondingly clamped and mated in the mating grooves.

[0049] Specifically, the convex structure can be a flanging structure provided on the edge side wall of the lock catch bottom plate 1, and this flanging structure is easy to be integrally formed when processing the lock catch bottom plate 1; the number and arrangement form of the convex structures can be set according to actual needs. The size of the mating groove can be set slightly smaller than the size of the convex structure, so that the elastic deformation ability of the buffer block 2 can be used to make the convex structure tightly clamped with the corresponding mating groove, forming a good limiting effect, so as to provide other connection points between the buffer block 2 and the lock catch bottom plate 1 in addition to the buckling ribs 21, and can further improve the connection stability between the buffer block 2 and the lock catch bottom plate 1.

[0050] Optionally, referring to Figures 1 to 3, the convex structure extends upward, and the side wall of the convex structure is provided with a horizontally extending anti - buckling part (not shown in the figure), and the anti - buckling part is used for buckling in the mating groove.

[0051] Specifically, when the convex structure extends upward from the perspective shown in Figure 1 , by setting the horizontally extending anti - buckling part, a biting effect can be formed on the mating groove in the horizontal direction, avoiding the upward movement and detachment of the buffer block 2 from the convex structure under vibration and other conditions, thereby reducing the probability of relative sliding and 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 - buckling parts can be flexibly set according to actual needs and are not limited here.

[0052] Preferably, corresponding recesses (not shown in the figure) can be provided in the mating groove corresponding to the anti - buckling parts, and the recesses also extend in the horizontal direction, so that the connection stability between the buffer block 2 and the latch bottom plate 1 can be further improved through the buckling fit between the anti - buckling parts and the recesses.

[0053] Optionally, referring to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 11 , the top of the buffer block 2 has a main guiding surface 23, and the main guiding surface 23 is inclined upward along the closing direction of the vehicle door body 5. The higher side of the main guiding surface 23 is docked with the limiting surface 22; the main guiding surface 23 is used for abutting against the lock body 3 during the closing process of the vehicle door body 5 to block the movement of the lock body 3 above the limiting surface 22.

[0054] Specifically, taking the XYZ coordinate system shown in Figure 1 as an example, the X - axis and the Y - axis are horizontally arranged, and the Z - axis is vertically arranged. The closing direction of the vehicle door body 5 is the horizontal direction on the XY plane; the main guiding surface 23 is located on the upper - side end face of the buffer block 2, and the main guiding surface 23 is inclined along both the closing direction of the vehicle door body 5 and the positive direction of the Z - axis. As shown in Figures 4 to 7 , in the state where the vehicle door body 5 is open, the side of the main guiding surface 23 closer to the lock body 3 is the lower side, and the side of the main guiding surface 23 farther from the lock body 3 is the higher side and is docked with 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 guiding surface 23 should be lower than the lowest point of the lock body 3. Based on the above settings, referring to Figures 8 to 11, during the closing process of the vehicle door body 5, the lower part of the lock body 3 will first come into contact with the main guiding surface 23; as the closing action of the vehicle door body 5 continues, the inclined main guiding surface 23 will exert an elastic force on the lock body 3 moving with the vehicle door body 5. This elastic force will gradually increase with the closing of the vehicle door body 5 and hinder the movement of the lock body 3, thereby providing a certain buffering effect on the closing action of the vehicle door body 5 and preventing the vehicle door body 5 from impacting and damaging the lock body 3 and the lock catch ring 11 due to excessive closing force; in addition, the main guiding surface 23 can provide a certain guiding effect on the lock body 3, enabling the lock body 3 to gradually transition along the main guiding surface 23 and finally move above the limiting surface 22. During the movement of the lock body 3, the elastic force exerted 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 22, the elastic force exerted by the buffer block 2 on the lock body 3 in the positive Z-axis direction reaches the maximum. This can prevent the resistance exerted by the buffer block 2 on the lock body 3 from being too large due to the overly high setting of the limiting surface 22, which makes it difficult for the lock body 3 to reach above the limiting surface 22, and can also prevent the inability to effectively support the lock body 3 that has moved into place in the Z-axis direction due to the overly low setting of the limiting surface 22.

[0055] Optionally, referring to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 11 , the top of the buffer block 2 has an auxiliary guiding surface 24, and the auxiliary guiding surface 24 is inclined downward along the closing direction of the vehicle door body 5; the higher side of the main guiding surface 23 is docked with the first side part of the limiting surface 22, and the higher side of the auxiliary guiding surface 24 is docked with the second side part of the limiting surface 22, and the first side part and the second side part are arranged oppositely.

[0056] Specifically, both the main guiding surface 23 and the auxiliary guiding surface 24 are located on the upper end face of the buffer block 2. As shown in Figures 4 to 7 , in the state where the vehicle door body 5 is open, the main guiding surface 23 is located on the side of the limiting surface 22 close to the lock body 3, and the auxiliary guiding surface 24 is located on the side of the limiting surface 22 away from the lock body 3. Referring to Figures 8 to 11, by setting the auxiliary guiding surface 24, on the one hand, the area of the limiting surface 22 can be reduced, avoiding excessive obstruction to the lock body 3 due to the overly large covering area of the limiting surface 22, thus preventing the problem of the door body 5 not closing smoothly; on the other hand, the auxiliary guiding surface 24 can be symmetrically arranged with respect to the limiting surface 22 relative to the main guiding surface 23. When the installation direction of the buffer block 2 is reversed, the auxiliary guiding surface 24 can be used as the main guiding surface 23, so as to avoid the problem that the buffer block 2 cannot be used normally due to the operator's negligence in reverse installation of the buffer block 2, improving the fault tolerance; it can be understood that when the installation direction of the buffer block 2 is reversed, in the state where the door body 5 is open, the auxiliary guiding surface 24 becomes the main guiding surface 23 close to the lock body 3, while the main guiding surface 23 becomes the auxiliary guiding surface 24 far from the lock body 3.

[0057] Optionally, referring to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 9 and Figure 10 , the lock catch base plate 1 is used to move on the vehicle body 4 in a direction parallel to the limiting surface 22, and the lock catch base plate 1 is used to be locked to the vehicle body 4 through the first threaded fastener 6.

[0058] Specifically, taking the XYZ coordinate system shown in Figure 1 as an example, the X-axis and Y-axis are horizontally arranged, the Z-axis is vertically arranged, and the limiting surface 22 is parallel to the XY plane; one of the lock catch 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 lock catch base plate 1 and the vehicle body 4 can be provided with a threaded hole, so that the lock catch base plate 1 can move along the XY plane within the cooperation range of the oblong hole / oblong arc hole and the threaded hole; when the lock catch base plate 1 moves relative to the vehicle body 4 in place, 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 lock catch 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 lock catch base plate 1 on the XY plane can be realized, so that the lock catch ring 11 can be more accurately buckled with the lock body 3, thereby improving the matching accuracy between the lock catch ring 11 and the lock body 3.

[0060] Optionally, referring to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 9 and Figure 10, on one side of the latch base plate 1 for fitting with the vehicle body 4, there is a protective layer (not shown in the figure). The protective layer can provide protection for the mounting surface of the latch base plate 1 to prevent damage to the mounting surface of the latch base plate 1 due to scraping and collision during the process of adjusting the mounting position. Among them, the protective layer can adopt a steel gasket or a plastic protective shell.

[0061] Optionally, referring to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 9 and Figure 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, and 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 1 to 12 , the present 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 latched with the latch ring 11.

[0063] In this embodiment, the vehicle door assembly refers to a complete vehicle door structure used for covering the cabin space such as the passenger compartment, the engine compartment, the trunk, etc. on transportation tools such as automobiles, trucks, aircraft (including flying cars), for example Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 12 the double-opening 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 to 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 22 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, making it not easy for the door body 5 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 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 part, 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 closed-ring structure setting form of the buffer block 2, the lock ring 11 can play a certain limiting role on the buffer block 2, which is more convenient to buckle the buckling rib 21 on the lock base plate 1, and the coverage range of the buffer block 2 can be limited to the area that will inevitably contact the lock body 3 around the lock ring 11, without covering the entire lock base plate 1 with the buffer block 2. In this way, 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 too large 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 4 to 11 , 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).

[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 22 is parallel to the XY plane, and the Z-axis is perpendicular to the limiting surface 22; an oblong hole can be provided at one of the lock body 3 and the vehicle door body 5, and a threaded hole can be provided 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 on 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 complete the buckling with the buckle ring 11 more accurately, and the fitting accuracy between the lock body 3 and the buckle ring 11 is improved; in addition, the vertical distance between the lock body 3 and the buffer block 2 can 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 1 to 12 , 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 to cover the cabin spaces such as the passenger compartment, engine compartment, and trunk of the vehicle, such as Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 12 the split tailgate at the rear of the car shown, which is not limited here.

[0070] Since the vehicle 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 latch bottom plate 1. During the closing process of the vehicle door body 5, the lock body 3 moves with the vehicle door body 5 above the buffer block 2 and is buckled and matched with the latch ring 11 on the latch bottom plate 1. At this time, the limiting surface 22 at the top of the buffer block 2 can buffer and support the lock body 3 above, and then buffer and support the vehicle door body 5 in the gravity direction. 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 it difficult for the vehicle door body 5 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 latch ring 11 in the gravity direction, ensuring that the lock body 3 and the latch ring 11 can be normally buckled and matched, and the vehicle door body 5 can be smoothly closed and opened, thus improving the locking reliability of the vehicle door body 5 and improving the user experience; in addition, through the connection and cooperation between the buffer block 2 and the latch bottom plate 1, the buffer block 2 and the latch bottom plate 1 can be integrated into a whole structural member, without separately arranging a buffer device outside the latch 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 closed-ring structure setting form of the buffer block 2, the latch ring 11 can play a certain limiting role on the buffer block 2, which is more convenient to buckle the buckling rib 21 on the latch bottom plate 1, and the coverage range of the buffer block 2 can be limited to the area that will inevitably contact the lock body 3 around the latch ring 11, without covering the entire latch bottom plate 1 with the buffer block 2. In this way, 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 latch bottom plate 1 and it is not convenient to install the latch bottom plate 1 on the vehicle body 4 can be avoided.

[0071] The above description is only an exemplary embodiment of the present application, and does 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 directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
