Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a door assembly and a vehicle. Background Technology

[0002] Currently, some vehicles are designed with a double-door structure, where two doors are rotatably installed on both sides of the same door frame. The two doors work together to open and close, creating a large opening that meets the needs of passengers getting on and off the vehicle and loading and unloading goods, providing a better user experience.

[0003] In typical open parking scenarios, this type of double-door structure opens normally and performs well. However, in actual use, vehicles are often parked in confined spaces such as when parking is limited, there are obstacles on the side, in narrow alleys, or when adjacent vehicles are parked close together. The rear doors, being longer in the longitudinal direction, require more turning space to open. In confined spaces, the opening angle of the rear doors is easily limited, preventing them from opening to the appropriate angle for passengers to get in and out. This severely hinders passengers' normal entry and exit, reducing the vehicle's usability and adaptability to different scenarios.

[0004] Therefore, how to balance the large opening function of the double-door structure with the door opening requirements in narrow space conditions has become an urgent technical problem to be solved.

[0005] In view of the above, this application is hereby submitted. Summary of the Invention

[0006] To address the aforementioned technical problems, this application provides a door assembly and a vehicle that can solve the technical problem of balancing the large opening function of a double-door structure with the door opening requirements in narrow space conditions.

[0007] In a first aspect, this application provides a door assembly that is rotatably connected to the door frame of a vehicle; the door assembly includes: a first door body and a support member; a first hinge structure is provided on one side of the first door body; the support member is detachably connected to the side of the first door body opposite to the first hinge structure; the support member includes a housing structure and a second assembly structure connected to the housing structure, the second assembly structure being detachably connected to a support clutch member provided on the door frame; wherein, the door assembly can switch between a linked state and a separated state; when the door assembly is in the linked state, the support member is connected to the first door body, and the second assembly structure is separated from the support clutch member; when the door assembly is in the separated state, the support member is unlocked from the first door body and locked to the support clutch member through the second assembly structure.

[0008] The door assembly provided in this application features a detachable support component from the first door body. When the door assembly is in the detached state, the support component is locked to the vehicle's door frame via a second assembly structure and can detach from the first door body, not rotating with it, thus reducing the turning space required to open the door assembly. The first door body can independently open to a larger angle in confined spaces, facilitating passenger entry and exit, while simultaneously meeting the requirements for both large opening capacity and use in narrow environments.

[0009] In some implementations, the outer shell structure extends continuously along the edge of the corresponding side of the first door body, and end plates are provided at both ends of the outer shell structure along its own extension direction, with at least one end plate connected to the second assembly structure.

[0010] In some implementations, the end plate at the upper edge of the outer shell structure near the door frame is designated as the upper end plate, which extends obliquely toward the front side of the outer shell structure along the direction close to the upper edge.

[0011] In some implementations, the second assembly structure connected to the upper end plate extends obliquely from the upper end plate toward the back side of the outer shell structure in a direction close to the upper frame, and the extended end of the second assembly structure is locked to the support clutch component connected to the upper frame.

[0012] In some implementations, the end plate at the lower edge of the outer shell structure near the door frame is designated as the lower end plate, which is located above the lower edge. The second assembly structure connected to the lower end plate extends from the lower end plate toward the lower edge, and the portion of the second assembly structure near the back of the outer shell structure is locked to the support clutch component connected to the lower edge.

[0013] In some implementations, the lower end plate is connected to a third positioning structure, which extends toward the lower frame and the end face of the extended end of the third positioning structure contacts the lower frame.

[0014] In some implementations, the outer shell structure includes an outer shell body and a first abutment. The outer shell body is detachably connected to the first door body, and the first abutment is connected to the outer shell body and extends from the outer shell body to the back side of the first door body.

[0015] In some implementations, the first door body is provided with a first shielding part, which is connected to the front side of the first door body and extends toward the support member.

[0016] In some implementations, the outer shell structure includes a first sidewall facing the first door body, and the portion of the first sidewall near the front side of the outer shell structure is provided with a first recessed portion that is recessed inward, and the projection of the first recessed portion along the front side of the outer shell structure coincides with the first shielding portion.

[0017] Secondly, this application provides a vehicle including the door assembly of the first aspect.

[0018] The vehicle provided in this application, by including the door assembly of the first aspect, achieves the same beneficial effects. Specifically, the supporting component and the first door body are designed to be separable. When the door assembly is in the separated state, the supporting component is locked to the vehicle's door frame via the second assembly structure and can be separated from the first door body, not rotating with it, thus reducing the turning space required to open the door assembly. The first door body can independently open to a larger opening angle in confined spaces, facilitating passenger entry and exit, while simultaneously meeting the requirements for both large opening capacity and use in narrow environments.

[0032] The following is a detailed description of this application.

[0033] Embodiments of this application provide a door assembly and a vehicle that can solve the problem of how to balance the large opening function of a double-door structure with the door opening requirements in narrow space conditions.

[0034] like Figures 1 to 13 As shown in the embodiment of this application, the door assembly 1 is rotatably connected to the door frame 31 of the vehicle; the door assembly 1 includes: a first door body 11 and a support member 12; a first hinge structure 111 is provided on one side of the first door body 11; the support member 12 is detachably connected to the side of the first door body 11 opposite to the first hinge structure 111; the support member 12 includes a housing structure 121 and a second assembly structure 125 connected to the housing structure 121, the second assembly structure 125 is detachably connected to a support clutch member 32 provided on the door frame 31; when the door assembly 1 is in the linkage state, the support member 12 is connected to the first door body 11, and the second assembly structure 125 is separated from the support clutch member 32; when the door assembly 1 is in the separated state, the support member 12 is unlocked from the first door body 11, and locked connected to the support clutch member 32 through the second assembly structure 125.

[0035] The door assembly 1 can be applied to the front door or the rear door of a vehicle, or to both the front door and the rear door. In this application, the rear side refers to the side facing the interior of the vehicle compartment; the front side refers to the side facing the exterior of the vehicle.

[0036] The vehicle body 3 has a door frame 31, and a support clutch component 32 is installed on the door frame 31. The door assembly 1 is openably fitted into the door frame 31. The door assembly 1 can switch between a linked state and a separated state. When the door assembly 1 is in the linked state, the support component 12 can rotate synchronously with the first door body 11. When the door assembly 1 is in the separated state, the first door body 11 can be moved relative to the support component 12.

[0037] Under normal circumstances, the door assembly 1 is in a linked state. When the door assembly 1 is opened, the support member 12 unlocks from the door frame 31 of the vehicle body 3. The support member 12 rotates synchronously with the first door 11 around the first hinge structure 111, completing the opening and closing action of the door assembly 1. When the vehicle is in a narrow parking space, the door assembly 1 switches from the linked state to the separated state, and the support member 12 is locked to the door frame 31. At this time, the passenger can open the first door 11 alone. The first door 11 rotates around the first hinge structure 111, while the support member 12 remains fixed to the door frame 31 and does not rotate.

[0038] With the above configuration, the support component 12 and the first door body 11 are designed to be separable. When the door assembly 1 is in the separated state, the support component 12 is locked to the door frame 31 of the vehicle through the second assembly structure 125 and can be separated from the first door body 11, without rotating with the first door body 11, thus reducing the turning space required to open the door assembly 1. The first door body 11 can independently open to a larger opening angle in narrow door opening environments, facilitating passenger entry and exit from the vehicle, while also meeting the requirements for large opening capacity and use in narrow scenarios.

[0039] In one embodiment of this application, the second assembly structure 125 includes a push-spring lock, and the supporting clutch component 32 includes a slot. The push-spring lock is engaged and locked with the slot by manually pressing the push-spring lock, and can be separated and unlocked by pressing again.

[0040] In another embodiment of this application, the second assembly structure 125 includes an electromagnetic latch, and the supporting clutch component 32 includes a corresponding lock hole. The extension and retraction of the electromagnetic latch are controlled by an electronic control signal to achieve locking and disengagement.

[0041] like Figure 1 , Figure 2 , Figure 9 and Figure 10As shown, in another embodiment of this application, the outer shell structure 121 extends continuously along the edge of the corresponding side of the first door body 11, and both ends of the outer shell structure 121 along its own extension direction are provided with end plates 1214, and at least one end plate 1214 is connected to the second assembly structure 125.

[0042] The end plates 1214 at both ends of the outer shell structure 121 are connected to the second assembly structure 125, so that the support component 12 is locked to the door frame 31 at the upper and lower ends respectively.

[0043] When the vehicle is in a narrow parking space, the user triggers the door assembly 1 to enter the disengaged state. The support component 12 is locked to the support clutch component 32 of the door frame 31 by the second assembly structure 125 on its two end plates 1214. At this time, the first door body 11 rotates outward around the first hinge structure 111. Since the outer shell structure 121 extends continuously along the edge of the first door body 11 and is fixed at both ends, it does not swing with the first door body 11.

[0044] With the above configuration, the outer shell structure 121 extends continuously to cooperate with the second assembly structure 125 of the end plates 1214 at both ends, which stably limits the support component 12 to the door frame 31 in the separated state, thereby improving the fixation stability of the support component 12 in the separated state.

[0045] In some embodiments, the outer shell structure 121 includes an outer shell body 1211, and both end plates 1214 are welded and fixed to the outer shell body 1211.

[0046] like Figure 1 , Figure 2 and Figure 9 As shown in the embodiment of this application, the end plate 1214 of the outer shell structure 121 near the upper frame 311 of the door frame 31 is set as the upper end plate 1214a, and the upper end plate 1214a extends obliquely toward the positive side of the outer shell structure 121 along the direction near the upper frame 311.

[0047] With the above configuration, the inclined extension structure of the upper end plate 1214a blocks the path of water infiltration, avoids water accumulation inside the support component 12 and at the connection of the door frame 31, thereby preventing the risk of rust, icing or short circuit of electronic components caused by water accumulation, and thus improving the long-term reliability and durability of the door assembly 1 in a humid environment.

[0048] In some embodiments, the upper frame 311 includes a first side portion 3111 and a second side portion 3112 arranged sequentially from the front side to the back side; the first side portion 3111 extends obliquely towards the support member 12 from the front side to the back side; the second side portion 3112 connects with the first side portion 3111 and extends towards the support member 12; preferably, the plate surface of the second side portion 3112 is disposed facing the front side of the upper frame 311.

[0049] In some embodiments, a third side 3113 is connected to one end of the second side 3112 away from the first side 3111, and the third side 3113 extends to the back side of the housing structure 121.

[0050] In some embodiments, a drainage micro-groove is provided on the surface of the upper end plate 1214a opposite to the upper frame 311 of the door frame 31. The drainage micro-groove is arranged in an inclined direction to accelerate the drainage speed of water accumulated in the gap.

[0051] like Figure 1 , Figure 2 and Figure 9 As shown in the embodiment of this application, the second assembly structure 125 connected to the upper end plate 1214a extends obliquely from the upper end plate 1214a toward the back side of the outer shell structure 121 in a direction close to the upper frame 311, and the extended end of the second assembly structure 125 is locked connected to the support clutch component 32 connected to the upper frame 311.

[0052] With the above configuration, the inclined extended second assembly structure 125 converts the locking force of the supporting clutch component 32 into a lateral tensioning effect, effectively suppressing the offset of the supporting component 12 away from the door frame 31, thereby improving the connection stiffness and vibration resistance of the door assembly 1 with the door frame 31 in the separated state.

[0053] In some embodiments, the clutch support component 32 includes a lock cylinder mechanism 321 and a second lock tongue 322. The lock cylinder mechanism 321 can drive the second lock tongue 322 to move, and the second lock tongue 322 is locked to the corresponding second assembly structure 125.

[0054] In some embodiments, the second assembly structure 125 is annular, and the second locking tongue 322 extends to the inner ring side of the second assembly structure 125.

[0055] In some embodiments, the second latch 322 of the upper frame 311, which is connected to the supporting clutch component 32, extends toward the front side of the upper frame 311 and is connected to the corresponding second assembly structure 125.

[0056] In some embodiments, the second side 3112 of the upper frame 311 is connected to the support clutch component 32. Preferably, the support clutch component 32 is installed inside the upper frame 311, the second side 3112 has an opening, the second latch 322 extends to the outside of the second side 3112 through the opening, and is connected to the corresponding second assembly structure 125.

[0057] like Figure 1 and Figure 11As shown in the embodiment of this application, the upper plate 1214a is connected to a first positioning structure 127, the first positioning structure 127 extends toward the upper frame 311, and the first positioning structure 127 contacts the second positioning structure 313 provided on the upper frame 311.

[0058] In some embodiments, the first positioning structure 127 extends along the front side to the inside of the support member 12, and the extended end of the first positioning structure 127 is disposed toward the second positioning structure 313.

[0059] In some embodiments, the second positioning structure 313 is connected to the front side of the second side portion 3112, and a positioning groove is formed on the front side of the second positioning structure 313. The extended end of the first positioning structure 127 is fitted into the positioning groove in a suitable shape. Preferably, the positioning groove is a tapered groove.

[0060] In some embodiments, when the support member 12 is in the closed position, the peripheral wall of the first positioning structure 127 is in close contact with the groove wall of the positioning groove, and the end face of the extended end of the first positioning structure 127 is spaced apart from the bottom of the positioning groove. This provides clearance, so that when the support member 12 is subjected to an external impact, the first positioning structure 127 can move towards the bottom of the positioning groove and push the groove wall of the positioning groove to elastically expand, thereby absorbing part of the impact force and reducing the impact force of the support member 12 on the door frame 31.

[0061] like Figure 1 , Figure 2 and Figure 10 As shown in the embodiment of this application, the end plate 1214 of the outer shell structure 121 near the lower frame 312 of the door frame 31 is set as the lower end plate 1214b, which is located above the lower frame 312; the second assembly structure 125 connected to the lower end plate 1214b extends from the lower end plate 1214b toward the lower frame 312, and the part of the second assembly structure 125 near the back side of the outer shell structure 121 is locked to the support clutch component 32 connected to the lower frame 312.

[0062] The second assembly structure 125 connected to the lower end plate 1214b extends vertically or approximately vertically from the lower end plate 1214b toward the lower frame 312.

[0063] With the above configuration, the support clutch component 32 connected to the lower frame 312 provides only a tension force toward the back of the lower frame 312 to the second assembly structure 125 without bearing any weight, thereby reducing the load and wear risk of the support clutch component 32 and the second assembly structure 125 connected to the lower frame 312, and thus improving the structural durability and operational reliability of the door assembly 1 when switching between linkage and separation states.

[0064] In some embodiments, the second latch 322 of the lower frame 312, which is connected to the supporting clutch component 32, extends toward the front side of the lower frame 312 and is connected to the corresponding second assembly structure 125.

[0065] In some embodiments, the lower frame 312 includes a fourth side portion 3121 extending in the direction from the front side to the back side. Preferably, a support clutch member 32 is installed inside the lower frame 312, and the fourth side portion 3121 has an opening. The second assembly structure 125 connected to the lower end plate 1214b can be moved through the opening into the fourth side portion 3121 and connected to the support clutch member 32 located inside the fourth side portion 3121.

[0066] In some embodiments, the back end of the fourth side portion 3121 is connected to a fifth side portion 3122, which extends to the back side of the housing structure 121.

[0067] In some embodiments, the housing structure 121 includes a third blocking portion 1215 and a fourth blocking portion 1216; the third blocking portion 1215 is connected to one end of the housing body 1211 near the upper frame 311 and extends to the front side of the upper frame 311; the fourth blocking portion 1216 is connected to one end of the housing body 1211 near the lower frame 312 and extends to the front side of the lower frame 312. Preferably, both the third blocking portion 1215 and the fourth blocking portion 1216 are flush with the front side of the housing body 1211.

[0068] like Figure 1 , Figure 2 and Figure 12 As shown in the embodiment of this application, the lower end plate 1214b is connected to a third positioning structure 128. The third positioning structure 128 extends toward the lower frame 312, and the end face of the extended end of the third positioning structure 128 contacts the lower frame 312.

[0069] The third positioning structure 128 extends from the lower end plate 1214b toward the lower frame 312. The extended end of the third positioning structure 128 forms an end face that contacts the lower frame 312 of the door frame 31. In the installed state of the support member 12, the third positioning structure 128 acts as a rigid support point, bearing part of the load generated by the weight of the support member 12.

[0070] Through the above settings, the third positioning structure 128 establishes a hard contact support between the lower end plate 1214b and the lower frame 312, effectively sharing the self-weight load of the support component 12, thereby reducing the stress load on the second assembly structure 125 and the support clutch component 32, preventing deformation or failure caused by excessive stress on the second assembly structure 125, and thus improving the structural stability and service life of the support component 12 in the separated state of the door assembly 1.

[0071] In some embodiments, a fourth positioning structure 314 is provided on the side of the lower frame 312 facing the support member 12, and the lower frame 312 contacts the third positioning structure 128 through the fourth positioning structure 314. Preferably, the fourth positioning structure 314 protrudes from the lower frame 312 toward the support member 12.

[0072] In some embodiments, the end face of the extension end of the third positioning structure 128 extends obliquely toward the support member 12 in the direction from the front side to the back side, and the end face of the extension end of the fourth positioning structure 314 is also correspondingly set as a matching oblique surface; the end face of the extension end of the third positioning structure 128 and the end face of the extension end of the fourth positioning structure 314 are in contact.

[0073] In some embodiments, the fourth positioning structure 314 is connected to the fourth side portion 3121.

[0074] In some embodiments, the end face of the third positioning structure 128 is provided with a wear-resistant pad, which slides in contact with the fourth positioning structure 314 to reduce frictional loss during the opening and closing process.

[0075] like Figure 3 , Figure 4 and Figure 8 As shown in the embodiments of this application, the outer shell structure 121 includes an outer shell body 1211 and a first support portion 1212. The outer shell body 1211 is detachably connected to the first door body 11, and the first support portion 1212 is connected to the outer shell body 1211. The first support portion 1212 extends from the outer shell body 1211 to the back side of the first door body 11.

[0076] The first support portion 1212 extends from the outer shell body 1211 toward the back side of the first door body 11 and contacts the back side of the first door body 11, thereby preventing the first door body 11 from shifting to the back side and improving the stability of the positioning assembly of the first door body 11 and the support component 12.

[0077] With the above configuration, the first support portion 1212 provides effective limiting support for the first door body 11, reducing the amount of intrusion of the outer shell structure 121 into the vehicle body under impact load, and reducing the risk of deformation caused by excessive indentation of the first door body 11.

[0078] In some embodiments, the first support portion 1212 is integrally connected to the outer casing body 1211.

[0079] In some embodiments, the vehicle further includes a second door 2, which is disposed within the same door frame 31 as the door assembly 1. The second door 2 is located on the side of the support member 12 opposite to the first door 11, and the second door 2 and the support member 12 are detachably connected. Preferably, the outer shell structure 121 further includes a second abutment 1213, which extends from the outer shell body 1211 to the back side of the second door 2.

[0080] like Figure 3 , Figure 4 and Figure 8 As shown in the embodiment of this application, the first door body 11 is provided with a first blocking part 112, the first blocking part 112 is connected to the front side of the first door body 11, and the first blocking part 112 extends toward the support member 12.

[0081] With the above-mentioned configuration, the first shield 112 blocks the path of foreign objects into the interior of the door, reduces the erosion of the internal structure of the door by dust and mud, thereby reducing the risk of hinge structure jamming or electrical component failure caused by the accumulation of foreign objects, and thus improving the sealing and durability of the door assembly 1 under harsh working conditions.

[0082] In some embodiments, a flexible sealing strip is provided on the edge of the first shielding part 112 facing the outer shell body 1211. When the first door 11 is closed, the sealing strip undergoes elastic deformation and adheres to the surface of the outer shell body 1211 to further improve the dustproof and waterproof rating.

[0083] In some embodiments, the second door body 2 is provided with a second blocking part 23, which is connected to the front side of the second door body 2 and extends toward the support member 12.

[0084] like Figure 3 , Figure 4 and Figure 8 As shown in the embodiment of this application, the outer shell structure 121 includes a first sidewall facing the first door body 11. The portion of the first sidewall near the front side of the outer shell structure 121 is provided with a first recess that is recessed inward. The projection of the first recess along the front side of the outer shell structure 121 coincides with the first blocking portion 112.

[0085] Through the above configuration, the fitting structure of the first recess and the first shielding part 112 enhances the positioning accuracy and anti-misalignment capability of the two, effectively suppresses the shaking and abnormal noise of the door during frequent opening and closing, and thus improves the repeatability of the door assembly 1 in the closed position under linkage and separation states.

[0086] In some embodiments, the portion of the first recess near the front side of the outer casing 1211 is provided with a shielding protrusion extending toward the first door 11, the shielding protrusion being connected to a third sealing member 17, and the third sealing member 17 making sealing contact with the back side of the first shielding portion 112.

[0087] In some embodiments, the outer shell structure 121 includes a second sidewall facing the second door body 2, and a portion near the front side of the outer shell structure 121 is provided with a second recessed portion that is recessed inward, and the projection of the second recessed portion along the front side of the outer shell structure 121 coincides with the second blocking portion 23.

[0088] like Figures 2 to 6 As shown in the embodiments of this application, the door assembly 1 includes a linkage clutch component 13; a first assembly structure 124 is provided on the side of the support component 12 facing the first door body 11; the linkage clutch component 13 is disposed on the first door body 11, and the linkage clutch component 13 includes a locking pin structure 131, which is detachably connected to the first assembly structure 124; wherein, the door assembly 1 can switch between a linkage state and a disengagement state; when the door assembly 1 is in the linkage state, the locking pin structure 131 is connected to the first assembly structure 124, and the support component 12 and the first door body 11 move synchronously; when the door assembly 1 is in the disengagement state, the locking pin structure 131 is separated from the first assembly structure 124, and the first door body 11 can move relative to the support component 12.

[0089] With the above settings, when the door assembly 1 is in the linkage state, the locking pin structure 131 remains connected to the first assembly structure 124 of the support component 12, forming a stable limiting support for the support component 12, and ensuring that the support component 12 and the first door body 11 move stably and synchronously.

[0090] In some embodiments, the door frame 31 of the vehicle is provided with a support clutch component 32, which is detachably connected to the support component 12; when the door assembly 1 is in the linkage state, the support clutch component 32 is separated from the support component 12; when the door assembly 1 is in the separation state, the support clutch component 32 is connected to the support component 12; when the support component 12 is separated from the first door body 11, the support component 12 can be connected to the door frame 31 through the support clutch component 32, thereby preventing the support component 12 from falling off.

[0091] like Figure 2 and Figure 8 As shown, in the embodiments of this application, a first door lock component 14 is also included, which is disposed on the first door body 11; when the door assembly 1 is in a separated state, the first door body 11 is detachably connected to the support component 12 through the first door lock component 14.

[0092] When the vehicle is in a narrow parking space, the user first operates the linkage clutch component 13 to disengage the locking pin structure 131 from the first assembly structure 124, and then keeps the latch of the first door lock component 14 engaged with the locking point of the support component 12. At this time, although the first door body 11 is disengaged from the support component 12, the two are still connected at the edges through the first door lock component 14. When the first door body 11 is opened around the first hinge structure 111, the support component 12 does not swing accordingly. When passengers need to get off the vehicle, they can unlock the first door lock component 14 and then open the first door body 11.

[0093] With the above settings, the first door lock component 14 provides support and positioning constraints for the first door body 11 and the support component 12 after the lock pin structure 131 is separated, so as to avoid the first door body 11 and the support component 12 from undergoing unexpected displacement due to their own weight or external force at the moment of unlocking, thereby improving the structural stability of the door assembly 1 in the separated state.

[0094] In some embodiments, the first door lock component 14 is provided with a movable first latch 141, and the first latch 141 is detachably connected to the latch structure 126 provided on the side of the support component 12 facing the first door body 11.

[0095] In some embodiments, the first latch 141 is provided with a first locking hook portion, which is locked to the annular locking structure 126. Preferably, the first locking hook is located on the front side of the locking structure 126 near the support member 12, and the first locking hook is locked to the portion of the locking structure 126 near the front side of the support member 12.

[0096] In some embodiments, the first door lock component 14 includes a first handle, which is tractively connected to a first latch 141. The first handle is located on the back and / or front side of the first door body 11. Passengers can use the first handle to lock or unlock the first latch 141 and the support component 12.

[0097] In some embodiments, the first door lock component 14 includes a first drive member, which is convexly connected to the first latch 141. The first drive member can drive the first latch 141 to lock and unlock with the support component 12.

[0098] In some embodiments, at least two linkage clutch components 13 are provided, and each linkage clutch component 13 is arranged along the edge of the first door body 11 toward the support component 12. The first door lock component 14 is disposed between two of the linkage clutch components 13.

[0099] like Figures 2 to 6 As shown in the embodiments of this application, the locking pin structure 131 includes a locking pin body 1311 and a locking pin protrusion 1312; the locking pin protrusion 1312 is disposed on the side of the locking pin body 1311 facing the first assembly structure 124; the locking pin protrusion 1312 is inserted and engaged with the first assembly structure 124.

[0100] The locking pin body 1311 is reciprocally mounted inside the first door body 11 in a direction that moves towards or away from the support member 12. The outer contour of the locking pin protrusion 1312 matches the internal cavity of the first assembly structure 124. The locking pin protrusion 1312 moves synchronously with the locking pin body 1311. When the locking pin structure 131 is in the extended state, the locking pin protrusion 1312 is inserted into the interior of the first assembly structure 124, forming a plug-in fit relationship, thereby locking the support member 12 and the first door body 11 into a linked whole.

[0101] Through the above configuration, the insertion and engagement of the locking pin protrusion 1312 and the first assembly structure 124 restricts the relative displacement between the support component 12 and the first door body 11, effectively improving the connection rigidity of the two doors in the linkage state and reducing vibration and abnormal noise during the opening process; at the same time, the locking pin body 1311 only needs to perform simple linear reciprocating motion to realize the state switching of the door assembly 1, improving the smoothness of the clutch action and the connection stability.

[0102] In some embodiments, the locking pin protrusion 1312 is integrally formed or fastened to the side surface of the locking pin body 1311 facing the first assembly structure 124.

[0103] In some embodiments, the locking pin protrusion 1312 is cylindrical, and the axis of the locking pin protrusion 1312 is parallel to the moving direction of the locking pin structure 131. The first assembly structure 124 is provided with a locking hole that matches the shape of the locking pin protrusion 1312. Preferably, the locking pin protrusion 1312 is cylindrical, and the first assembly structure 124 is provided with a corresponding circular locking hole.

[0104] In some embodiments, the locking pin protrusion 1312 is a wedge-shaped or trapezoidal cross-section boss, and the first assembly structure 124 is provided with a corresponding dovetail groove. After the wedge-shaped locking pin protrusion 1312 is embedded in the dovetail groove, it can withstand a large shear force.

[0105] In some embodiments, the locking pin structure 131 is movably disposed within the first door body 11, and the first door body 11 has a corresponding first connecting hole on its edge facing the support member 12. When the door assembly 1 is in a separated state, the locking pin protrusion 1312 is located inside the first door body 11; when the door assembly 1 is in a linked state, the locking pin protrusion 1312 protrudes from the edge of the first door body 11 facing the support member 12 via the first connecting hole and engages with the first assembly structure 124.

[0106] In some embodiments, the first assembly structure 124 is disposed on the outer edge of the support member 12 facing the first door body 11, and the surface of the first assembly structure 124 facing the first door body 11 has a lock hole that engages with the locking pin protrusion 1312.

[0107] like Figure 7As shown, the first assembly structure 124 includes an assembly base 1241 and a bushing 1242. The assembly base 1241 has a locking hole, and the bushing 1242 is fitted into the locking hole. The outer peripheral wall of the bushing 1242 is in close contact with the inner peripheral wall of the locking hole, and the inner peripheral wall of the bushing 1242 is in contact with the outer peripheral wall of the locking pin protrusion 1312. The hardness of the bushing 1242 is less than the hardness of the assembly base 1241.

[0108] The mounting base 1241 has a mounting protrusion protruding towards the first door body 11 in the middle, and a lock hole is opened in the mounting protrusion. The mounting base 1241 has openings on both sides of the mounting protrusion, and screws or rivets pass through the openings on the mounting base 1241 to connect with the support member 12, so that the mounting base 1241 and the support member 12 are fixedly connected.

[0109] like Figures 2 to 5 As shown in the embodiments of this application, the locking pin body 1311 is connected to at least two locking pin protrusions 1312; each locking pin protrusion 1312 is inserted and engaged with the corresponding first assembly structure 124.

[0110] Through the above configuration, the multiple locking pin protrusions 1312 and the multi-point insertion and cooperation of the first assembly structure 124 constitute an anti-torsion constraint mechanism, which disperses the concentrated stress on the locking pin structure 131, thereby suppressing the torsional deformation of the locking pin structure 131 in the linkage state and reducing the risk of single-point locking failure.

[0111] In some embodiments, the locking pin protrusions 1312 are arranged at intervals on a spatial plane perpendicular to the moving direction of the locking pin structure 131.

[0112] In one embodiment of this application, at least a portion of the locking pin protrusions 1312 are arranged along the extending direction of the first door body 11 toward the edge of the support member 12.

[0113] like Figures 2 to 5 As shown, in another embodiment of this application, at least some of the locking pin protrusions 1312 are arranged along the moving direction of the first door body 11.

[0114] The direction of movement of the first door 11 refers to the tangential direction of the movement trajectory of the first door 11 when it opens or closes around the first hinge structure 111.

[0115] Through the above configuration, the locking pin protrusions 1312 arranged along the moving direction of the first door body 11 form a multi-level impact-resistant force transmission structure, which disperses the impact force generated by lateral collision, thereby slowing down the intrusion speed of the support component 12 into the vehicle interior and effectively improving the impact resistance of the locking pin structure 131.

[0116] In some embodiments, two locking pin protrusions 1312 are arranged at intervals on the locking pin body 1311 along the moving direction of the first door body 11. The diameter of the locking pin protrusion 1312 closer to the front side of the first door body 11 is larger than the diameter of the other locking pin protrusions 1312, so as to cope with the main impact load.

[0117] In the embodiments of this application, the linkage clutch component 13 includes a second handle, which is connected to the locking pin structure 131. The second handle is movably installed on the first door body 11. Passengers can operate the linkage clutch component 13 to move back and forth through the second handle, thereby switching the door assembly 1 between the linkage state and the disengagement state.

[0118] like Figures 2 to 5 As shown in the embodiments of this application, the linkage clutch component 13 further includes a driving component 132, which can drive the locking pin structure 131 to move in a direction close to the first assembly structure 124.

[0119] The drive unit 132 is installed inside the first door body 11 and is connected to the locking pin body 1311. When the drive unit 132 is energized, it drives the locking pin body 1311 to move the locking pin protrusion 1312 toward the support member 12 until the locking pin protrusion 1312 is inserted into the first assembly structure 124, thus completing the locking. When the drive unit 132 moves in the opposite direction, the locking pin structure 131 retracts, thus unlocking.

[0120] With the above settings, the drive device 132 replaces the manual operation of the clutch or tool disassembly, realizing the electric feeding and retraction of the locking pin structure 131, thereby shortening the operation time of the door assembly 1 switching between the linked state and the separated state, and improving the work efficiency of state switching.

[0121] In one embodiment of this application, the driving device 132 is a linear motor, which drives the locking pin structure 131 to move toward the first assembly structure 124.

[0122] like Figures 2 to 5 As shown, in another embodiment of this application, the linkage clutch component 13 further includes a transmission structure 133, which is disposed between the driving component 132 and the locking pin structure 131. The transmission structure 133 includes a transmission screw 1331 and a transmission seat 1332. The transmission screw 1331 is connected to the driving end of the driving component 132, and the transmission seat 1332 is connected to the locking pin structure 131. The transmission seat 1332 is threadedly sleeved on the transmission screw 1331.

[0123] The transmission screw 1331 extends along the direction close to the first assembly structure 124. The end of the transmission screw 1331 closest to the driving component 132 is connected to the driving end of the driving component 132 via a coupling or gear pair. The driving component 132 can drive the transmission screw 1331 to rotate around its axis. The transmission seat 1332 has an internal threaded hole that matches the external thread of the transmission screw 1331. The transmission seat 1332 is threadedly fitted onto the outer circumference of the transmission screw 1331. When the transmission screw 1331 rotates, its rotational motion is converted into linear displacement of the transmission seat 1332 along the axial direction of the transmission screw 1331 through thread engagement, thereby synchronously displacing the locking pin structure 131.

[0124] Through the above settings, the threaded transmission of the lead screw 1331 and the transmission seat 1332 accurately converts the rotational motion of the drive component 132 into the axial feed motion of the locking pin structure 131, thereby realizing the conversion of motion form, increasing the output thrust of the locking pin structure 131 when it is inserted into the first assembly structure 124, and reducing the risk of the drive component 132 stalling or jamming.

[0125] In some embodiments, the transmission screw 1331 is a ball screw, the transmission seat 1332 is a ball nut, and circulating balls are provided between the ball screw and the ball nut to reduce the coefficient of friction and improve the transmission efficiency.

[0126] In other embodiments, the surface of the transmission screw 1331 is provided with a double-threaded screw, and the transmission seat 1332 is provided with a corresponding double-threaded internal screw. The double-threaded engagement increases the axial displacement of the transmission seat 1332 per unit time, thereby accelerating the engagement and disengagement response speed of the locking pin structure 131.

[0127] like Figures 2 to 6 As shown in the embodiment of this application, the transmission seat 1332 is connected to the side of the locking pin structure 131 facing away from the first assembly structure 124. The locking pin structure 131 has a recessed receiving groove 1313 on the side facing the transmission seat 1332. The transmission screw 1331 extends movably through the transmission seat 1332 into the receiving groove 1313.

[0128] After the transmission screw 1331 passes through the transmission seat 1332, its end away from the driving component 132 extends movably into the receiving groove 1313. When the transmission seat 1332 drives the transmission screw 1331 to rotate, the locking pin structure 131 moves axially with the transmission seat 1332, and the end of the transmission screw 1331 slides synchronously in the receiving groove 1313 without exceeding the contour boundary of the locking pin structure 131.

[0129] With the above configuration, the receiving groove 1313 houses the protruding end of the transmission screw 1331 inside the locking pin structure 131, avoiding the structural expansion caused by the transmission screw 1331 being suspended outward; thereby reducing the overall size of the linkage clutch component 13, reducing the occupation of the limited arrangement space inside the first door body 11, and improving the space utilization rate of the door assembly 1.

[0130] In some embodiments, the transmission structure 133 includes a fixing member 1333, and the transmission seat 1332 has a through hole. The fixing member 1333 passes through the hole of the transmission seat 1332 and is connected to the locking pin structure 131. Preferably, the transmission seat 1332 has symmetrical openings on both sides of the transmission screw 1331, and the two fixing members 1333 pass through the corresponding openings and are connected to the locking pin structure 131.

[0131] In some embodiments, the depth of the receiving groove 1313 is greater than or equal to the length of the transmission screw 1331 extending into the receiving groove 1313 when in the unlocked position.

[0132] In some embodiments, the inner diameter of the receiving groove 1313 is greater than or equal to the outer diameter of the transmission screw 1331.

[0133] In some embodiments, the inner wall of the receiving groove 1313 is coated with a solid lubricating coating, and the end of the transmission screw 1331 is fitted with a wear-resistant bushing. The outer wall of the bushing slides in conjunction with the inner wall of the receiving groove 1313 to reduce friction and wear when the transmission screw 1331 reciprocates within the receiving groove 1313.

[0134] In some embodiments, a buffer washer is provided at the bottom of the receiving groove 1313. When the locking pin body 1311 moves to the limit position in the direction close to the driving device 132, the end face of the transmission screw 1331 abuts against the buffer washer. The buffer washer absorbs the impact energy and reduces the mechanical impact noise and wear generated by the transmission screw 1331.

[0135] In the embodiments of this application, the linkage clutch component 13 includes a locking pin housing 134, and a locking pin structure 131 is movably embedded inside the locking pin housing 134; the locking pin structure 131 has a limiting protrusion 1314 with a protruding surface on at least one side facing the locking pin housing 134; a limiting groove 1341 is correspondingly formed on the inner wall of the locking pin housing 134, and the limiting protrusion 1314 is movably embedded in the limiting groove 1341.

[0136] The locking pin housing 134 is fixedly installed in the internal cavity of the first door body 11, and the locking pin structure 131 is reciprocally embedded in the locking pin housing 134 in a direction close to the first assembly structure 124. The limiting groove 1341 extends in a direction close to the first assembly structure 124, and the limiting protrusion 1314 is movably embedded in the limiting groove 1341. The limiting protrusion 1314 matches the limiting groove 1341, and when the limiting protrusion 1314 slides in the limiting groove 1341, it restricts the rotational freedom of the locking pin structure 131 about its own axis.

[0137] Through the above settings, the fitting of the limiting protrusion 1314 and the limiting groove 1341 provides circumferential constraint for the locking pin structure 131, preventing the locking pin structure 131 from deflecting around the axis in the moving or locked state, thereby ensuring the alignment accuracy of the locking pin protrusion 1312 during the insertion of the first assembly structure 124, avoiding jamming or scratching caused by posture misalignment, thereby improving the smoothness of the clutch action and the long-term operational reliability of the door assembly 1.

[0138] In some embodiments, the limiting protrusion 1314 is elongated, and the length direction of the limiting protrusion 1314 extends along the direction close to the first assembly structure 124. The limiting groove 1341 is a matching elongated through groove, and the elongated mating surface provides a larger anti-torsional arm.

[0139] In some embodiments, limiting protrusions 1314 are provided on both sides of the locking pin body 1311, and limiting grooves 1341 are provided on both sides of the inner wall of the locking pin housing 134. The double-sided limiting structure further enhances the stability of anti-deflection and balances the lateral force on the locking pin structure 131 during movement.

[0140] In some embodiments, the locking pin housing 134 has an opening on the side facing the first assembly structure 124; the locking pin structure 131 can extend through the opening of the locking pin housing 134 and be inserted into the first assembly structure 124.

[0141] like Figure 3 , Figure 4 and Figure 8 As shown in the embodiments of this application, the support component 12 includes a shell structure 121 and a foam structure 122 with pores; the shell structure 121 is detachably connected to the side of the first door 11 opposite to the first hinge structure 111; the foam structure 122 fills the interior of the shell structure 121.

[0142] The foam structure 122 is filled inside the outer shell structure 121, and the foam structure 122 is a porous material with pores. In the event of a side collision or passenger leaning against it, the external force first acts on the outer shell structure 121 of the supporting component 12. The outer shell structure 121 transfers the load to the internal foam structure 122. The foam structure 122 undergoes plastic deformation through its internally distributed pores, absorbing and dissipating the impact energy, thereby improving the overall impact resistance of the door assembly 1.

[0143] By filling the outer shell structure 121 of the support component 12 with a foam structure 122, the impact resistance of the support component 12 is improved, and the cavity resonance inside the outer shell structure 121 is eliminated, thereby improving the rigidity and NVH performance of the support component 12; and reducing the risk of injury to the door assembly 1 and the occupants in the vehicle due to side collisions in narrow space conditions.

[0144] In some embodiments, the foamed structure 122 may be made of foamed aluminum material.

[0145] In some embodiments, the foam structure 122 is coated with a sound-absorbing coating. Preferably, the sound-absorbing coating is attached to the inner walls of the pores of the foam structure 122. Specifically, the sound-absorbing coating may be made of polyurethane or acrylate materials. This further reduces wind noise and road noise transmission during vehicle operation.

[0146] In one embodiment of this application, the pores of the foam structure 122 are uniformly distributed at various locations of the foam structure 122. Preferably, the porosity of the foam structure 122 is greater than or equal to 70% and less than or equal to 90%.

[0147] like Figure 3 , Figure 4 and Figure 8 As shown, in another embodiment of this application, the porosity of the foam structure 122 is set to gradually decrease from the outer periphery near the inner wall of the outer shell structure 121 to the center.

[0148] During vehicle operation, airflow flows along the sides of the vehicle body 3 and forms turbulence on the surface of the door assembly 1. This airflow excites the outer shell structure 121 of the support component 12 to vibrate, thereby generating noise. Sound waves and vibration energy are transmitted from the outer shell structure 121 of the support component 12, first reaching the outer periphery of the foam structure 122. The outer periphery of the foam structure 122 has a higher porosity, which can significantly attenuate the incoming high-frequency sound waves and effectively weaken the inward transmission of noise. The central region is a high-density structure with low porosity, which can provide stable rigid support. At the same time, the gradient pore structure can reduce the overall effective density of the foam structure 122, significantly reducing the overall weight and motion inertia of the support component 12.

[0149] Through the above configuration, the high-porosity outer peripheral region of the foam structure 122 achieves both lightweight design of the support component 12 and significantly improves noise absorption efficiency, effectively optimizing the in-vehicle acoustic environment. The dense central region with low porosity can greatly enhance the overall structural strength. When the support component 12 is subjected to lateral impact, it can ensure that the load is evenly transferred from the outer shell structure 121 to the dense core of the foam structure 122, avoiding local stress concentration problems, preventing premature structural crushing failure, and improving the overall collision resistance of the door.

[0150] In some embodiments, the change in porosity of the foamed structure 122 can be achieved by controlling the cooling rate during the preparation process, or by using a layered foaming process to form the foamed structure 122 so that the porosity decreases from the outer periphery to the center.

[0151] In some embodiments, the foamed structure 122 is configured with at least two segments along the outer periphery to the center direction; the porosity of each segment decreases progressively along the outer periphery to the center direction. Preferably, the number of segments in the foamed structure 122 is one of 2, 3, 4, 5 and 6, or it can be an integer greater than 6.

[0152] In some embodiments, the porosity of the foamed structure 122 is distributed in a smooth decreasing manner from the outer periphery to the center.

[0153] In one embodiment of this application, the outer shell structure 121 extends continuously along the edge of the corresponding side of the first door body 11, and at least two foam structures 122 are arranged at intervals along the extension direction of the outer shell structure 121.

[0154] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, in another embodiment of this application, the outer shell structure 121 extends continuously along the edge of the corresponding side of the first door body 11, and the foam structure 122 extends continuously along the extension direction of the outer shell structure 121.

[0155] The outer shell structure 121 is generally long and narrow, extending continuously from one end of the corresponding side edge of the first door body 11 to the other end.

[0156] Through the above configuration, the continuously extending foam structure 122 eliminates structural weak points, improves the overall bending and impact resistance of the support component 12 along the entire length of the edge of the first door body 11, and enables the foam structure 122 to absorb impact energy uniformly at any position, avoiding local collapse or breakage.

[0157] In some embodiments, the outer shell structure 121 is arc-shaped along the continuous extension trajectory of the edge of the first door body 11 to match the curved shape of the edge of the first door body 11, and the foam structure 122 bends and extends continuously to adapt to the streamlined appearance requirements of the vehicle body side.

[0158] In the embodiments of this application, the porosity of the foam structure 122 gradually decreases from both ends to the center along the extension direction of the foam structure 122.

[0159] When a vehicle is involved in a side impact, the impact point is typically concentrated in the middle section of the support member 12 along its extension direction. Because the central region of the foamed structure 122 has lower porosity and higher density, it can provide greater compressive strength and energy absorption capacity, effectively absorbing and dissipating impact energy.

[0160] Through the above configuration, the lower porosity in the middle of the foam structure 122 ensures that the core area of ​​the support component 12, which is susceptible to impact, has sufficient impact resistance, reducing the deformation of the middle area under lateral impact. At the same time, the higher porosity and lower density of the two ends of the foam structure 122 significantly reduce the overall weight of the support component 12 while ensuring basic protection at both ends.

[0161] In some embodiments, the foamed structure 122 is configured with at least three segments from both ends to the center along the extension direction; the porosity of each segment decreases progressively from both ends to the center along the extension direction of the foamed structure 122. Preferably, the number of segments of the foamed structure 122 is one of 3, 4, 5, 6 and 7, or it can be an integer greater than 7.

[0162] In some embodiments, the porosity of the foamed structure 122 is distributed in a smooth decreasing manner from both ends to the center along the extension direction.

[0163] In the embodiments of this application, the porosity of the largest portion of the foamed structure 122 is greater than or equal to 80% and less than or equal to 90%; and the porosity of the smallest portion of the foamed structure 122 is greater than or equal to 55% and less than or equal to 65%.

[0164] If the maximum porosity of the foamed structure 122 exceeds 90%, the foam matrix content is too low, the pore walls are too thin, and it is prone to brittle fracture rather than plastic buckling under lateral impact, resulting in decreased energy absorption stability. If the maximum porosity is below 80%, the viscous friction path of sound waves in the high-porosity layer is insufficient, the high-frequency noise absorption coefficient is reduced, and the lightweighting effect is weakened. Furthermore, if the minimum porosity is below 55%, the compressive strength of the central impact-resistant section is excessive and the weight increases significantly, affecting the operational stability of the door assembly 1 and easily causing the door assembly 1 to sink. If it is above 65%, the central area may experience excessive indentation in a lateral impact at a limited angle, resulting in insufficient protection margin.

[0165] With the above settings, the upper limit of porosity of 80% to 90% ensures that the high porosity area has sufficient noise reduction and lightweight effect, avoiding the protective failure caused by the material being too brittle; the lower limit of porosity of 55% to 65% ensures that the low porosity area has sufficient impact resistance, reducing excessive deformation after the center is hit.

[0166] In some embodiments, the porosity of the largest portion of the foamed structure 122 is greater than or equal to 83% and less than or equal to 87%; and the porosity of the smallest portion of the foamed structure 122 is greater than or equal to 58% and less than or equal to 62%. Preferably, the porosity of the largest portion of the foamed structure 122 is greater than or equal to 84% and less than or equal to 86%; and the porosity of the smallest portion of the foamed structure 122 is greater than or equal to 59% and less than or equal to 61%.

[0167] In some embodiments, the porosity of the most porous portion of the foamed structure 122 can be any one of 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, and 90%. The porosity of the least porous portion of the foamed structure 122 can be any one of 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, and 65%.

[0168] like Figure 8 As shown in the embodiments of this application, the support component 12 further includes an inner beam structure 123, which is disposed inside the outer shell structure 121; the foam structure 122 is disposed in the space between the inner beam structure 123 and the outer shell structure 121.

[0169] The cross-sectional shape of the inner beam structure 123 is adapted to the inner cavity cross-section of the outer shell structure 121. The outer wall surface of the inner beam structure 123 and the inner wall surface of the outer shell structure 121 together form a space for filling the foam structure 122.

[0170] With the above configuration, the inner beam structure 123 provides internal rigid support for the support component 12. The outer wall of the inner beam structure 123 defines the compression boundary of the foam structure 122, preventing the foam structure 122 from expanding freely inward under impact load and reducing energy absorption efficiency, thereby improving the overall bending stiffness and impact resistance of the support component 12 and reducing the amount of indentation deformation of the outer shell structure 121 under lateral collision.

[0171] In some embodiments, the inner beam structure 123 is a hollow structure to reduce the overall weight of the inner beam structure 123.

[0172] In the embodiments of this application, the outer shell structure 121 is provided with end plates 1214 at both ends along the extension direction, the inner beam structure 123 extends continuously along the extension direction of the outer shell structure 121, and the two ends of the inner beam structure 123 along the extension direction are respectively connected to the corresponding end plates 1214.

[0173] With the above configuration, the inner beam structure 123 extends continuously and is connected to the end plates 1214 at both ends, so that the support component 12 obtains uniform rigid support along the entire longitudinal length, reducing the overall flexural deformation of the outer shell structure 121 under lateral impact. Furthermore, the closed frame formed by the end plates 1214 and the inner beam structure 123 disperses the local impact force to the entire length of the support component 12, reducing the stress peak at any position, thereby improving the impact resistance of the support component 12.

[0174] In some embodiments, the end of the inner beam structure 123 is fixed to the end plate 1214 by welding, riveting or bolting.

[0175] like Figure 3 , Figure 4 and Figure 8 As shown in the embodiments of this application, the outer shell structure 121 includes an outer shell body 1211 and a first support portion 1212. The outer shell body 1211 is detachably connected to the first door body 11, and the first support portion 1212 extends from the outer shell body 1211 to the back side of the first door body 11. The foam structure 122 includes a first foam portion 1221 filled in the outer shell body 1211 and a second foam portion 1222 filled in the first support portion 1212.

[0176] The first abutment portion 1212 extends from the outer shell body 1211 toward the back side of the first door body 11 and contacts the back side of the first door body 11, thereby preventing the first door body 11 from shifting to the back side and improving the stability of the positioning assembly of the first door body 11 and the support component 12. At the same time, when an external object impacts the first door body 11 from the side, the first abutment portion 1212 is located on the back side of the first door body 11 in the impact direction, and the first abutment portion 1212 forms a rigid limiting support relative to the first door body 11, preventing the first door body 11 from moving further toward the center of the vehicle body 3. The second foam portion 1222 filled inside the first abutment portion 1212 provides additional compression buffer during this limiting contact process, absorbs residual displacement energy, and avoids local stress concentration caused by hard contact.

[0177] With the above configuration, the first support portion 1212 provides effective limiting support for the first door body 11, reducing the amount of intrusion of the outer shell structure 121 into the vehicle body under impact load, and reducing the risk of deformation caused by excessive indentation of the first door body 11; in addition, the second foam portion 1222 provides buffer energy absorption when in limiting contact, attenuating the impact peak transmitted to the back side of the first door body 11.

[0178] In some embodiments, the vehicle further includes a second door 2, which is disposed within the same door frame 31 as the door assembly 1. The second door 2 is located on the side of the support member 12 opposite to the first door 11, and the second door 2 and the support member 12 are detachably connected. Preferably, the outer shell structure 121 further includes a second abutment 1213, which extends from the outer shell body 1211 to the back side of the second door 2; the foam structure 122 further includes a third foam portion 1223 filled within the second abutment 1213.

[0179] In one embodiment of this application, the first abutment portion 1212 is separately disposed from the outer shell body 1211, and the first foaming portion 1221 and the second foaming portion 1222 are disposed relatively independently. Preferably, the first abutment portion 1212 is welded to the outer shell body 1211.

[0180] like Figure 3 , Figure 4 and Figure 8 As shown, in another embodiment of this application, the interior of the first support portion 1212 is connected to the interior of the outer shell body 1211; the porosity of the second foam portion 1222 gradually increases from the end near the first foam portion 1221 to the end away from the first foam portion 1221.

[0181] The first support portion 1212 is integrally connected to the outer shell body 1211, and the interior of the first support portion 1212 is connected to the interior of the outer shell body 1211. The first foaming portion 1221 and the second foaming portion 1222 are integrally formed. The porosity of the second foaming portion 1222 near the connection end of the first foaming portion 1221 is lower, and the porosity of the end farther away from the first foaming portion 1221 is higher.

[0182] It can be seen that the lower porosity at the connection between the second foaming part 1222 and the first foaming part 1221 increases the local hardness of the area, reduces the probability of the first support part 1212 bending and deforming relative to the outer shell body 1211, and reduces the risk of stress concentration at the turning point; at the same time, the higher porosity at the end of the second foaming part 1222 away from the first foaming part 1221 reduces the overall weight of the first support part 1212 and reduces the influence of the support component 12 on the rotational inertia of the door assembly 1.

[0183] In some embodiments, the porosity of the second foamed portion 1222 near the connection end of the first foamed portion 1221 is greater than or equal to 75% and less than or equal to 85%, and the porosity of the end away from the first foamed portion 1221 is greater than or equal to 80% and less than or equal to 90%. This gradient range achieves a balance between the bending strength of the connection end and the lightweight of the end. Preferably, the porosity of the second foamed portion 1222 near the end of the first foamed portion 1221 is greater than or equal to 78% and less than or equal to 82%, and the porosity of the end away from the first foamed portion 1221 is greater than or equal to 83% and less than or equal to 87%.

[0184] In some embodiments, the interior of the second support portion 1213 is connected to the interior of the outer shell body 1211; the porosity of the third foam portion 1223 gradually increases from the end near the first foam portion 1221 to the end away from the first foam portion 1221.

[0185] In some embodiments, the porosity of the third foaming portion 1223 near the first foaming portion 1221 is greater than or equal to 75% and less than or equal to 85%, and the porosity of the end away from the first foaming portion 1221 is greater than or equal to 80% and less than or equal to 90%. Preferably, the porosity of the third foaming portion 1223 near the first foaming portion 1221 is greater than or equal to 78% and less than or equal to 82%, and the porosity of the end away from the first foaming portion 1221 is greater than or equal to 83% and less than or equal to 87%.

[0186] like Figure 3 , Figure 4 , Figure 8 and Figure 13 As shown in the embodiments of this application, the door assembly 1 includes a first sealing member 15; the first sealing member 15 is connected to the side of the support member 12 near the first door body 11, and the first sealing member 15 is in sealing contact with the first door body 11.

[0187] With the above configuration, the first sealing component 15 fills the assembly gap between the first door body 11 and the supporting component 12, preventing external dust and rainwater from entering the carriage through the first door body 11 and the supporting component 12.

[0188] In some embodiments, the vehicle includes a second door 2, which is installed in the same door frame 31 as the door assembly 1. The second door 2 is disposed on the side of the support member 12 away from the first door 11, and the side of the second door 2 away from the support member 12 is rotatably connected to the door frame 31 through a second hinge structure 21.

[0189] In some embodiments, the door assembly 1 includes a sixth sealing member 18, which is connected to the support member 12 on the side near the second door body 2 and is in sealing contact with the second door body 2.

[0190] like Figure 3 , Figure 4 , Figure 8 and Figure 13 As shown in the embodiment of this application, the support member 12 is provided with a first abutment portion 1212, which extends to the back side of the first door body 11; the first sealing member 15 is connected to the first abutment portion 1212 and makes sealing contact with the back side of the first door body 11.

[0191] The supporting component 12 includes an outer shell structure 121, which includes an outer shell body 1211 and a first support portion 1212. The outer shell body 1211 is detachably connected to the first door body 11, and the first support portion 1212 is integrally formed with the outer shell body 1211.

[0192] The first sealing component 15 is connected to the front side of the first abutment portion 1212. The first sealing component 15 extends along the front side of the first abutment portion 1212 and makes a sealing contact with the first door body 11.

[0193] With the above configuration, the first support portion 1212 provides rigid support for the first sealing component 15 in the direction of the first door body 11, preventing the first sealing component 15 from being deformed or displaced by force, and improving the sealing stroke and sealing stability of the first sealing component 15.

[0194] In some embodiments, the distance between the first abutment 1212 and the back side of the first door 11 is less than the preset compression amount of the first sealing member 15, so as to ensure that the first sealing member 15 is always in a controllable compression state when the first door 11 is closed.

[0195] In some embodiments, a positioning groove is provided on the front side of the first support portion 1212, and a corresponding positioning protrusion is provided on the back side of the first sealing member 15. The positioning protrusion is inserted into the positioning groove to prevent the first sealing member 15 from detaching from the first support portion 1212 when the vehicle is bumpy or traveling at high speed.

[0196] In some embodiments, the support member 12 is provided with a second abutment portion 1213, which extends to the back side of the second door body 2; the sixth sealing member 18 is connected to the front side of the second abutment portion 1213 and makes sealing contact with the back side of the second door body 2.

[0197] like Figure 8 and Figure 13 As shown in the embodiments of this application, the support member 12 extends continuously along the corresponding side of the first door body 11, and the first sealing member 15 extends continuously along the extension direction of the support member 12.

[0198] The length of the support member 12 matches the length of the corresponding side portion of the first door body 11. The first sealing member 15 undergoes elastic compression synchronously at each position, forming a continuous and uninterrupted sealing interface.

[0199] With the above configuration, the continuously extending first sealing component 15 eliminates local breaks in the sealing interface, avoids weak sealing areas on the side of the door, and improves the sealing integrity between the support component 12 and the first door 11.

[0200] In some embodiments, the first sealing member 15 has a continuous hollow cavity inside along the extension direction, and the cross-section of the hollow cavity is elliptical to improve the uniformity of compression rebound of the long strip sealing strip over its entire length.

[0201] In some embodiments, the sixth sealing member 18 extends continuously along the extending direction of the support member 12.

[0202] like Figure 9 and Figure 13 As shown in the embodiment of this application, the support member 12 includes an upper connecting corner 1217 and a lower connecting corner 1218, which are respectively disposed at both ends of the support member 12; one end of the first sealing member 15 is connected to the upper connecting corner 1217, and the other end is connected to the lower connecting corner 1218.

[0203] The upper end of the support member 12 is connected to an upper joint 1217, and the lower end of the support member 12 is connected to a lower joint 1218. The upper end of the first sealing member 15 is fixedly connected to the upper joint 1217, and the lower end is fixedly connected to the lower joint 1218. The upper joint 1217 and the lower joint 1218 serve as anchoring bases at both ends of the first sealing member 15, so that the first sealing member 15 continuously abuts against the first door body 11.

[0204] With the above settings, the upper corner 1217 and the lower corner 1218 form fixed anchor points for the two ends of the first sealing component 15, avoiding the problem of gaps between the two ends of the long strip-shaped first sealing component 15 and the first door body 11 caused by the two ends of the first sealing component 15 lifting up, thereby improving the sealing stability of the first sealing component 15 at each position along the extension direction.

[0205] In some embodiments, grooves are provided on both the upper corner 1217 and the lower corner 1218 toward the first sealing member 15, and corresponding inserts are provided at both ends of the first sealing member 15. The inserts are pressed into the grooves to further improve the connection stability between the first sealing member 15 and the support member 12.

[0206] In some embodiments, both the upper connecting angle 1217 and the lower connecting angle 1218 are elongated strips. One end of the upper connecting angle 1217 protrudes from the side of the outer casing 1211 facing the first door 11 and is connected to the first sealing member 15; the other end protrudes from the side of the outer casing 1211 facing the second door 2 and is connected to the sixth sealing member 18. One end of the lower connecting angle 1218 protrudes from the side of the outer casing 1211 facing the first door 11 and is connected to the first sealing member 15; the other end protrudes from the side of the outer casing 1211 facing the second door 2 and is connected to the sixth sealing member 18. This allows the upper connecting angle 1217, the lower connecting angle 1218, the first sealing member 15, and the sixth sealing member 18 to cooperate to form an annular sealing mechanism.

[0207] In some embodiments, the upper corner 1217 and the lower corner 1218 are both located on the back side of the support member 12.

[0208] In some embodiments, the door frame 31 is connected to a fifth sealing member 33, which at least partially seals against the outer casing body 1211. Preferably, the fifth sealing member 33 has an annular structure.

[0209] In some embodiments, the door frame 31 includes an upper frame 311, which includes a first side portion 3111, a second side portion 3112, and a third side portion 3113 arranged sequentially from the front side to the back side. The first side portion 3111 extends obliquely towards the support member 12 from the front side to the back side. The second side portion 3112 connects to the first side portion 3111 and extends towards the support member 12. The end of the second side portion 3112 facing away from the first side portion 3111 is connected to the third side portion 3113, which extends to the back side of the outer shell structure 121. A corresponding portion of the fifth sealing member 33 is connected to the front side of the third side portion 3113. Preferably, the third side portion 3113 is located on the back side of the upper corner 1217, and a corresponding portion of the fifth sealing member 33 is located between the third side portion 3113 and the upper corner 1217.

[0210] In some embodiments, the door frame 31 includes a lower frame 312, which includes a fourth side 3121 extending from the front side to the back side and a fifth side 3122 connected to the back end of the fourth side 3121. The fifth side 3122 extends to the back side of the housing structure 121, and a corresponding portion of the fifth sealing member 33 is connected to the front side of the fifth side 3122. Preferably, the fifth side 3122 is located on the back side of the lower corner 1218, and a corresponding portion of the fifth sealing member 33 is located between the fifth side 3122 and the lower corner 1218.

[0211] In some embodiments, the fifth sealing member 33 contacts the back side of the upper corner 1217 and the lower corner 1218.

[0212] like Figure 8 As shown in the embodiments of this application, a second sealing component 16 is also included. The second sealing component 16 is connected to the first door body 11, and the second sealing component 16 is at least partially in sealing contact with the support component 12.

[0213] With the above configuration, the second sealing component 16 and the support component 12 form an additional sealing contact interface, which can fill the sealing blind area of ​​the first sealing component 15 and reduce the probability of external impurities intruding; and together with the first sealing component 15, they form a multi-seal structure, further improving the sealing reliability.

[0214] In some embodiments, the second sealing member 16 is an annular structure, and the second sealing member 16 is sleeved on the outer peripheral edge of the first door body 11, with the portion of the second sealing member 16 facing the support member 12 in sealing contact with the support member 12. Preferably, the second sealing member 16 is a hollow structure.

[0215] In some embodiments, the housing structure 121 includes a first sidewall facing the first door 11, and a portion of the first sidewall near the front side of the housing structure 121 is provided with a first recess that is recessed inward, and a second sealing member 16 contacts one end of the first recess near the back side of the housing structure 121.

[0216] With the above configuration, the first recess on the first sidewall can limit and avoid the second sealing component 16. The second sealing component 16 abuts against the end of the first recess near the back of the outer shell structure 121, which can not only position and constrain the second sealing component 16, preventing it from shifting or warping towards the back of the outer shell structure 121, but also ensure the positional accuracy of the sealing fit between the second sealing component 16 and the support component 12. At the same time, the first recess can accommodate part of the deformation allowance of the second sealing component 16. When the door is closed, the second sealing component 16 can stably abut against the corresponding end of the first recess, maintain the sealing pre-tightness, reduce the risk of sealing failure caused by assembly tolerances, further improve the sealing performance of the multiple seals, and reduce the possibility of impurities entering.

[0217] In some embodiments, the contact surface between the second sealing member 16 and the support member 12 is coated with a hydrophobic coating. Preferably, the surface contact angle of the hydrophobic coating is greater than 110°, which can reduce rainwater residue at the sealing interface.

[0218] In some embodiments, the second door 2 is provided with a fourth sealing member 24, which is at least partially in sealing contact with the support member 12.

[0219] In some embodiments, the fourth sealing member 24 is an annular structure, and is sleeved on the outer peripheral edge of the second door body 2, with the portion of the fourth sealing member 24 facing the support member 12 in sealing contact with the support member 12. Preferably, the fourth sealing member 24 is a hollow structure.

[0220] In some embodiments, the housing structure 121 includes a second sidewall facing the second door 2, and a portion of the second sidewall near the front side of the housing structure 121 is provided with a second recess that is recessed inward, and the fourth sealing member 24 contacts one end of the second recess near the back side of the housing structure 121.

[0221] like Figure 8 As shown, in the embodiments of this application, a first door lock component 14 is also included. The first door lock component 14 is disposed on the side of the first door body 11 facing the support component 12, and the first door lock component 14 and the support component 12 are detachably connected. Along the direction from the back side to the front side of the door assembly 1, the first sealing component 15 and the second sealing component 16 are respectively disposed on both sides of the first door lock component 14.

[0222] With the above settings, the first sealing component 15 and the second sealing component 16 respectively seal the connecting gaps on both sides of the first door lock component 14, preventing the first door lock component 14 from rusting or jamming due to mud, water, or dust, and improving the working reliability of the first door lock component 14.

[0223] In some embodiments, the first sealing member 15 and the second sealing member 16 are provided with guide ribs on opposite sides. The extension direction of the guide ribs is consistent with the extension direction of the support member 12, which can guide the water that has seeped into the sealing interface to the bottom of the door assembly 1 for discharge, thereby preventing water from accumulating in the door lock area.

[0224] like Figure 3 and Figure 4 As shown, in some embodiments, a linkage clutch component 13 is also included. The linkage clutch component 13 is disposed on the first door body 11, and the support component 12 is correspondingly provided with a first assembly structure 124. The linkage clutch component 13 and the first assembly structure 124 can be detachably connected. Along the direction from the back side to the front side of the door assembly 1, the first sealing component 15 and the second sealing component 16 are respectively disposed on both sides of the linkage clutch component 13.

[0225] like Figure 8 As shown, in some embodiments, the second door body 2 is provided with a second door lock component 22, which is located on the side of the second door body 2 facing the support component 12, and the second door lock component 22 is detachably connected to the support component 12; along the direction from the back side to the front side of the door assembly 1, the sixth sealing component 18 and the fourth sealing component 24 are respectively located on both sides of the second door lock component 22.

[0226] like Figure 8 As shown in the embodiment of this application, the first sealing member 15 is disposed near the back side of the support member 12; the door assembly 1 includes a third sealing member 17, which is connected to the side of the support member 12 facing the first door body 11 and disposed near the front side of the support member 12.

[0227] The third sealing component 17 extends continuously along the extension direction of the support component 12.

[0228] With the above configuration, the first sealing component 15 and the third sealing component 17 form a double-layer sealing interface on both sides of the support component 12, which reduces the amount of external noise transmitted into the car body, thereby maintaining good sound insulation performance. It can also prevent external impurities from entering the gap between the support component 12 and the first door body 11 from the front side of the door assembly 1, further improving the sealing effect of the door assembly 1.

[0229] In some embodiments, the interior of the third sealing member 17 is provided with a continuous hollow silencing cavity along its extending direction. Preferably, the silencing cavity is filled with sound-absorbing cotton, which can further improve the absorption effect of mid-to-high frequency traffic noise.

[0230] In some embodiments, a shock-absorbing pad is provided at the connection interface between the third sealing member 17 and the support member 12; this pad is used to attenuate the transmission of vibrations from the support member 12 to the third sealing member 17 during vehicle operation, and to prevent gaps from forming at the sealing interface due to high-frequency micro-movements.

[0231] like Figure 8 As shown in the embodiment of this application, a first blocking part 112 extending toward the support member 12 is provided on the front side of the first door body 11, and the third sealing member 17 is in sealing contact with the back side of the first blocking part 112.

[0232] The first shielding part 112 extends horizontally from the front side edge of the first door body 11 toward the support member 12.

[0233] With the above configuration, the first shielding part 112 and the third sealing part 17 cooperate to form a hidden sealing interface on the front, avoiding visible assembly seams and impurity accumulation between the supporting part 12 and the front of the first door body 11.

[0234] In some embodiments, the back side of the extended end of the first blocking part 112 is provided with a guide slope, which is inclined to abut against the front side of the third sealing member 17, so that the first door 11 can automatically align and press the third sealing member 17 when closed.

[0235] like Figure 8 As shown in the embodiment of this application, the third sealing member 17 extends from the support member 12 along the arrangement direction of the support member 12 and the first door body 11, and the front side of the third sealing member 17 is in sealing contact with the first shielding part 112.

[0236] With the above configuration, the third sealing component 17 converts the opening and closing force of the first door 11 into an oblique sealing and pressing force, which increases the effective sealing compression stroke, thereby maintaining the stability of the sealing contact between the third sealing component 17 and the first shielding part 112, and reducing the risk of wind noise and water leakage from the front gap.

[0237] In some embodiments, a wave spring sheet is embedded inside the third sealing component 17. The wave spring sheet is continuously arranged along the extension direction of the third sealing component 17, so that the third sealing component 17 has a constant rebound force after oblique compression, avoiding permanent plastic deformation of the sealing lip due to long-term use.

[0238] In some embodiments, the portion of the first recess near the front side of the outer casing 1211 is provided with a shielding protrusion extending toward the first door 11, and the third sealing member 17 is connected to the extended end face of the shielding protrusion, and the third sealing member 17 is in sealing contact with the back side of the first shielding portion 112.

[0239] Embodiments of this application also provide a vehicle including the door assembly 1 as described above.

[0240] With the above-described configuration, the same beneficial effects can be achieved by including the door assembly 1 of the above embodiment. Specifically, the support member 12 and the first door body 11 are designed to be separable. When the door assembly 1 is in the separated state, the support member 12 is locked to the vehicle's door frame 31 via the second assembly structure 125 and can be separated from the first door body 11, not rotating with it, thus reducing the turning space required to open the door assembly 1. The first door body 11 can independently open to a larger opening angle in confined spaces, facilitating passenger entry and exit, while simultaneously meeting the requirements for both large opening capacity and use in narrow environments.

[0241] In the embodiments of this application, a second door body 2 is also included; the second door body 2 and the door assembly 1 are disposed in the same door frame 31; one side of the second door body 2 is detachably connected to the side of the support member 12 that is away from the first door body 11, and the other side is rotatably connected to the door frame 31 through the second hinge structure 21.

[0242] In the linked state, the second door 2 and the door assembly 1 are connected and can rotate around their respective hinge structures to form a double door structure. In the separated state, the support member 12 is locked to the door frame 31, the first door 11 can move relative to the support member 12, and the second door 2 can also be disconnected from the support member 12 and opened independently.

[0243] The door assembly 1 can be applied to the front door of the vehicle, and the second door body 2 can be applied to the rear door of the vehicle; or the door assembly 1 can be applied to the rear door of the vehicle, and the second door body 2 can be applied to the front door of the vehicle.

[0244] In some embodiments, the second door body 2 is provided with a second door lock component 22, and the second door lock component 2 is provided with a movable third lock tongue 221. The third lock tongue 221 is detachably connected to the latch structure 126 provided on the side of the support component 12 facing the second door body 2.

[0245] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
