Description

Technical Field

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

[0002] With the diversification of consumer demand in the automotive market, concealed external handles, as an important component to enhance the aesthetics and aerodynamic performance of vehicles, are divided into two categories based on functional differences: high-end concealed electric external handles and low-end concealed manual external handles. Both need to be installed on the core load-bearing structure of the door window edge reinforcement plate to achieve stability in opening and closing the door.

[0003] The current method for compatible high- and low-spec door handles involves designing differentiated door sheet metal for different vehicle models. This involves redeveloping the exterior window trim reinforcement structure for models with electric door handles, adjusting the cut-edge dimensions, mounting points, and internal space layout. However, when installing larger high-spec electric door handles, the base structure of the electric door handle directly interferes with the exterior window trim reinforcement, preventing proper installation. Developing differentiated sheet metal requires additional investment in design, testing, and mold costs, significantly increasing the overall development cost of the door system and hindering cost control. In the manufacturing process, the production line needs to differentiate, identify, store, and assemble door sheet metal of different configurations, increasing the complexity of production management and potentially leading to assembly errors due to identification mistakes, thus reducing production efficiency and product yield.

[0004] Therefore, it is particularly important to develop a door structure and vehicle that can achieve seamless conversion between high and low trim hidden external handles without adjustment of the door sheet metal, by using a window sill reinforcement plate and a crash beam, and by fixing the window sill reinforcement plate and the crash beam in the target area. This would reduce the development cost of the door sheet metal and the difficulty of differentiating the manufacturing process, while also meeting the rigidity requirements of the mounting point and improving the overall performance and rigidity. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The current method of using compatible high- and low-end door handles causes direct interference between the base structure of the electric external handle and the outer window edge reinforcement plate when a larger high-end electric external handle needs to be installed, making proper installation impossible. This significantly increases the overall development cost and production management complexity of the door system and may also lead to assembly errors due to identification mistakes, reducing production efficiency and product qualification rate. Therefore, this application provides a door structure and vehicle that allows for seamless conversion between high- and low-end concealed external handles without adjustment of the door sheet metal, reduces the development cost and difficulty of identifying differences in door sheet metal production, meets the rigidity requirements of the mounting point, and improves overall performance and rigidity.

[0022] Please see Figure 1 , Figure 1 This is a schematic diagram of the overall structure of an electric handle car door according to an embodiment of the present invention. On one hand, this application provides a car door structure, which includes a car door body and a window sill reinforcing plate 1, the car door body and the window sill reinforcing plate 1 being fixedly connected; An obstacle avoidance structure 2 is provided on the window sill reinforcement plate, and an anti-collision beam 3 is provided on the door body. The anti-collision beam 3 is located on the side of the door body close to the window sill reinforcement plate 1. The anti-collision beam 3 and the window sill reinforcement plate 1 are fixedly connected in the target area.

[0023] In an optional embodiment, the target area is located at the end of the window sill reinforcement plate 1 away from the end connected to the door body, and the width of the target area is greater than or equal to a third preset distance, the third preset distance being 12mm-14mm.

[0024] Please see Figure 2 , Figure 2 This is a schematic diagram of a window sill reinforcement plate and anti-collision beam structure according to an embodiment of the present invention. Optionally, the door body is the basic load-bearing frame of the door structure and the mounting carrier for the window sill reinforcement plate 1, anti-collision beam 3, and external handle structure. It needs to provide a stable assembly benchmark for each component, while ensuring the overall structural integrity and strength of the door, meeting the daily opening and closing operation and basic protection requirements of the vehicle, and serving as a supporting structure for achieving compatibility with the external handle. The window sill reinforcement plate 1 is an assembly component of the external handle structure, which needs to be compatible with both high-end concealed electric external handles and low-end concealed manual external handles, providing assembly space for the external handles and avoiding structural interference; in conjunction with the anti-collision beam 3, it compensates for the potential stiffness loss due to the increased clearance space, ensuring the performance of the sheet metal during door opening and closing.

[0025] Optionally, the avoidance structure 2 is a structure designed on the window sill reinforcement plate 1 for the assembly of the external handle. The electric external handle integrates the actuator and controller module, and its overall size is larger than that of the manual external handle. The avoidance structure 2 needs to reserve sufficient space to avoid interference between the electric external handle base and the window sill reinforcement plate 1. The anti-collision beam 3 is a reinforcing component in the door structure that improves the overall performance. It is located on the side of the door body near the window sill reinforcement plate 1, specifically in the middle area of ​​the door, corresponding to the lower area of ​​the window sill reinforcement plate 1. The anti-collision beam 3 not only plays a basic role in door collision protection, but also, through its connection with the window sill reinforcement plate 1, compensates for the decrease in the stiffness of the window sill reinforcement plate 1 caused by the enlargement of the avoidance structure 2. At the same time, it improves the overall system stiffness and modal characteristics of the door, ensuring that both high-end and low-end external handles meet the door opening and closing quality requirements after installation.

[0026] Optionally, the outer window edge reinforcement plate is fixedly connected to the door body, providing a stable foundation for the outer handle mounting point. The target area specifically refers to the lower area of ​​the window edge reinforcement plate 1, corresponding to the upper area of ​​the anti-collision beam 3. The overlap length needs to meet the stiffness transfer requirements, and the third preset distance can be 13mm. The overlap length is the width of the target area, which is greater than or equal to 13mm. Because the avoidance structure 2 is enlarged according to the size of the electric outer handle, the original stiffness of the window edge reinforcement plate 1 will be affected. However, by using a rigid connection method such as welding or bolt overlap, the fixed connection between the anti-collision beam 3 and the window edge reinforcement plate 1 in the target area, the load of the window edge reinforcement plate 1 can be transferred to the anti-collision beam 3. The high stiffness of the anti-collision beam 3 can be used to improve the overall stiffness of the window edge reinforcement plate 1, thereby ensuring the stiffness requirements of the outer handle mounting point and improving the overall collision performance of the door.

[0027] In an optional embodiment, the window sill reinforcing plate 1 is provided with a mounting through hole, and the avoidance structure 2 is disposed at the edge of the mounting through hole; The door structure also includes a handle structure 4, which is disposed in the mounting through hole and is detachably connected to the window sill reinforcing plate 1.

[0028] Optionally, the mounting through hole is a hole on the window sill reinforcing plate 1 that adapts to the assembly of the handle structure 4, simultaneously meeting the assembly requirements of both high-end and low-end external handles. The size of the through hole can be set according to actual business needs and is not limited here. It can be designed based on the high-end concealed electric external handle. The electric external handle has an integrated actuator and controller module, so its structural size is larger. The mounting through hole needs to reserve enough space to accommodate the base and functional modules of the electric external handle to avoid structural interference during assembly. At the same time, the size of the through hole needs to take into account the assembly stability of the low-end manual external handle to ensure that there is no risk of shaking or displacement after the manual external handle is installed. The mounting through hole is the carrier for the handle structure 4 and also the reference positioning hole for connecting the external handle and the window sill reinforcing plate 1. The edge of the through hole needs to be machined to have a flat mounting surface to provide support for the mounting positioning structure of the handle structure 4, such as bolt holes and buckles, to ensure the verticality and coaxiality after installation, and to avoid door jamming or handle loosening due to installation deviation.

[0029] Optionally, the avoidance structure 2 is a structure designed around the edge of the mounting through hole. The avoidance structure 2 is continuously distributed along the entire edge of the mounting through hole and extends continuously along the inner edge of the mounting through hole. The starting end of the flange is flush with the hole wall of the through hole, and the end is raised, forming a stepped structure of the hole wall and the flange.

[0030] Optionally, handle structure 4 is a component that enables the door opening and closing function, encompassing both high-end concealed electric external handles and low-end concealed manual external handles, achieving universal assembly based on the same installation location. The base portion has uniform dimensions, ensuring that both electric and manual versions can be adapted to the size of the mounting hole; in the functional modules, the electric version integrates the actuator and controller module at the front of the base, while the manual handle does not, retaining only the basic cable connection structure. The main body of the handle base is embedded in the mounting hole, with the outer circumference of the base maintaining a uniform gap with the hole wall to ensure no jamming during assembly; the front end of the base is flush with the outer surface of the window sill reinforcement plate to prevent the handle from protruding too much and affecting door performance.

[0031] In an optional embodiment, the avoidance structure 2 is integrally formed with the window sill reinforcing plate 1, the avoidance structure 2 is a flanged structure, and the distance between the flanged structure and the outer side of the handle structure is greater than or equal to a first preset distance, the first preset distance being 4mm-6mm.

[0032] In an optional embodiment, the flange structure is raised in a direction away from the door body, and the height of the raised flange structure is 1.5mm-2.5mm.

[0033] Optionally, the avoidance structure 2 and the window sill reinforcement plate 1 are integrally formed by stamping and bending. The window sill reinforcement plate 1 uses high-strength steel plate as the base material. During the stamping stage, the edge area of ​​the installation through hole is bent in one go by a customized mold, so that the material at the edge of the through hole is raised in the preset direction to form a flange structure. Integral forming can ensure the structural continuity between the flange and the reinforcement plate.

[0034] Optionally, the distance between the flange and the outer side of the handle structure 4 must be greater than or equal to the first preset distance of 4mm-6mm. The first preset distance can be 5mm, that is, the distance between the flange and the outer side of the handle structure 4 is greater than or equal to 5mm. This dimension ensures that there is no friction interference when the handle structure 4 is assembled, and also leaves an installation gap to avoid collision noise between parts.

[0035] Optionally, the height of the raised edge structure can be set according to actual business needs, and is not limited here. For example, the height of the raised edge structure can be 2mm.

[0036] Alternatively, while a chamfered edge structure can accommodate a manual external handle, it weakens the structural strength of the through-hole edge. Designing the avoidance structure 2 as a flanged structure, with the flange curving away from the door body, expands the avoidance space inside the through-hole and enhances the local stiffness of the through-hole edge through the bending reinforcement effect, preventing edge deformation caused by the increased through-hole size. The avoidance structure 2 and the window edge reinforcement plate 1 are integrally molded, rather than being a post-assembly component. This design avoids stiffness loss or assembly errors caused by additional connections, ensuring the structural continuity between the avoidance structure 2 and the window edge reinforcement plate 1. It also simplifies the manufacturing process, eliminating the need for additional assembly steps and reducing manufacturing costs.

[0037] In an optional embodiment, the handle structure 4 includes a base structure on which a wire harness fixing structure 41 is provided, the wire harness fixing structure 41 being located at one end of the base structure near the anti-collision beam 3.

[0038] Please see Figure 3 , Figure 4 , Figure 3 This is a schematic diagram of a handle structure according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the overall structure of the manual handle on another car door according to an embodiment of the present invention. Optionally, the handle structure 4 needs to have the capability of integrated wiring harness adaptation. The electric handle has a wiring harness fixing structure 41 designed on its base, which can directly fix the wiring harness on the base to avoid friction between the wiring harness and the edge of the mounting hole. The manual version uses a pull wire snap-fit ​​structure on the base to ensure precise connection between the outward pull wire and the door lock mechanism. Both achieve the adaptation of two functional handles with the same mounting hole through the unified design of the base structure.

[0039] The wiring harness of the electric exterior handle needs to be connected to the controller inside the door. After fixing, the routing of the wiring harness is strictly restricted, which can avoid the wiring harness from easily rubbing against moving parts or rigid structures inside the door, as well as the problem of short circuit faults caused by damage to the wiring harness insulation layer due to long-term use. The wiring harness fixing structure 41 provides clear fixing points for the wiring harness. During assembly, there is no need to measure or adjust the position of the wiring harness. It can be directly snapped in, reducing assembly time. At the same time, the fixed wiring harness layout is neat, which facilitates quick identification and troubleshooting of problems during later after-sales maintenance.

[0040] In an optional embodiment, the door structure further includes a plurality of mounting and positioning holes 5, which are disposed on the window sill reinforcing plate 1 and are located on the outer side of the avoidance structure 2.

[0041] In an optional embodiment, the distance between the mounting positioning hole 5 and the outer side of the avoidance structure 2 is greater than or equal to a second preset distance, the second preset distance being 11mm-13mm.

[0042] Optionally, the number of mounting positioning holes 5 can be three, and they are evenly distributed in a triangle along the outer side of the avoidance structure 2. The three holes are located on the left, right, and bottom of the outer side of the flange, forming a stable three-point positioning structure. When the door is opened or closed, the handle structure 4 will bear the pulling or pushing force applied by the user. The three evenly distributed positioning holes can evenly transfer the load to the window sill reinforcing plate 1, avoiding sheet metal deformation or hole wear caused by local stress concentration.

[0043] Optionally, the second preset distance can be set according to actual business needs. For example, the second preset distance is 12mm, that is, the distance between the mounting positioning hole 5 and the outer side of the avoidance structure 2 is greater than or equal to 12mm. Even if the flange deforms, it will not affect the connection stability of the positioning hole, and at the same time, it avoids friction noise caused by the handle base and the flange being too close. For the low-end manual external handle, its base size is small. The 12mm distance between the mounting positioning hole 5 and the flange can ensure that the base has enough mounting surface to fit with the reinforcing plate, avoiding the shaking of the base due to the small mounting surface. For the high-end electric external handle, its base needs to accommodate the actuator and controller module. The larger distance can reserve space for the layout of the functional modules inside the base, avoid interference between the module and the connection structure of the positioning hole, and realize the same size to adapt to two types of handles.

[0044] In an optional embodiment, the handle structure 4 further includes a plurality of mounting positioning structures 42, the number of which is the same as the number of mounting positioning holes 5, and the mounting positioning structures 42 are connected to the window sill reinforcing plate 1 through the mounting positioning holes 5.

[0045] Optionally, there are 3 mounting and positioning structures 42, which correspond exactly to the positions of the 3 mounting and positioning holes 5 on the window sill reinforcement plate 1. This allows the two types of handles to share the same set of mounting references. The production line does not need to distinguish between the holes of the electric handle and the holes of the manual handle. It only needs to select the corresponding handle according to the configuration and directly connect the 3 mounting and positioning structures with the holes to complete the assembly, which greatly reduces the difficulty of differentiating the production and manufacturing process.

[0046] Optionally, during installation, after the base of the handle structure 4 is embedded into the mounting through hole of the window sill reinforcing plate 1, the three mounting positioning structures 42 are initially aligned with the mounting positioning holes 5. At this time, the position of the handle within the through hole is initially defined, with no obvious wobble. If it is a bolt connection, the bolt is passed through the mounting positioning hole 5 and engaged with the internal threaded boss of the mounting positioning structure 42 to ensure that the handle base and the reinforcing plate are tightly fitted. If it is a snap-fit ​​connection, axial force is applied to press the clips into the mounting positioning hole 5 until the barbs are fully engaged on the other side of the hole, confirming that the connection is in place.

[0047] Optionally, the detachable connection between the handle structure 4 and the window sill reinforcement plate 1 is achieved through the cooperation of the mounting positioning structure 42 and the preset mounting positioning holes 5. Specifically, the base of the handle structure 4 is provided with three mounting positioning structures 42, which can be, for example, a boss with internal threads or a detachable buckle, corresponding to the three preset mounting positioning holes 5 distributed around the mounting through hole on the window sill reinforcement plate 1, such as light holes or buckle holes. Detachable fixing is achieved by bolt connection or buckle connection. When bolted, the bolt passes through the preset mounting positioning hole 5 and engages with the threaded boss of the handle base to ensure a firm connection and facilitate subsequent disassembly and replacement. When buckled, an elastic buckle is designed inside the positioning hole. After the positioning structure 42 of the handle base is inserted, it is limited by the buckle. When disassembling, pressing the buckle can separate the parts. This setup requires no structural modifications to the window sill reinforcement plate 1. The configuration conversion between manual and electric handles can be completed simply by replacing the handle structure 4, effectively reducing the difficulty of differentiation identification in production and manufacturing. The production line does not need to distinguish between different sheet metals, but only needs to select the corresponding handle for assembly according to the configuration. At the same time, when the external handle malfunctions, the handle structure 4 can be disassembled and replaced separately without disassembling the door body or replacing the window sill reinforcement plate 1, reducing maintenance costs and labor time.

[0048] On the other hand, this application provides a vehicle that includes a door structure as described in any of the above embodiments.

[0049] The door structure provided in this application includes a door body and a window sill reinforcement plate 1, wherein the door body and the window sill reinforcement plate 1 are fixedly connected; an avoidance structure 2 is provided on the window sill reinforcement plate, and an anti-collision beam 3 is provided on the door body, wherein the anti-collision beam 3 is located on the side of the door body closer to the window sill reinforcement plate 1; the anti-collision beam 3 and the window sill reinforcement plate 1 are fixedly connected within the target area. The door structure provided in this application has the following beneficial effects: (1) By unifying the sheet metal structure of the car door, the installation through holes and avoidance structure are designed based on the size of the high-end hidden electric external handle, so that the same car door sheet metal can be compatible with the assembly of high-end and low-end external handles without adjustment, which significantly reduces the development cost of the car door system; at the same time, the production line does not need to distinguish and identify sheet metal parts of different configurations, which reduces the complexity of material management and the risk of assembly error, and improves production efficiency and pass rate. (2) The original cut edge structure of the window edge reinforcement plate is changed to a flanged structure to avoid interference with the assembly of the external handle and enhance the rigidity of the external handle installation point. At the same time, a door anti-collision beam is added and overlaps with the lower part of the window edge reinforcement plate in the target area to improve the overall performance of the door and further enhance the safety of the door.

[0050] (3) For the high-end hidden electric external handle, a dedicated wire harness fixing structure is set in the base structure to improve compatibility and ensure the stability of the electrical system. In addition, it facilitates the quick identification of the wire harness route and connection nodes during after-sales maintenance, reducing the difficulty of troubleshooting.
