Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0044] The car doors are equipped with window frames, and glass is installed inside the window frames to meet the needs of lighting, ventilation and visibility inside the vehicle.

[0045] However, in related technologies, the door's strength at the window frame is insufficient, causing the door to vibrate easily when opening and closing, affecting the quality of the door's operation.

[0046] Based on this, this utility model embodiment provides a car door and a vehicle. By providing a reinforcing structure in the closed cavity between the car door body and the window frame, the reinforcing structure is connected at least at the corner of the window opening. The reinforcing structure can expand to fill at least part of the gap between the car door body and the window frame. In this way, the reinforcing structure plays a structural support role between the car door body and the window frame, improving the structural strength and rigidity of the car door body and the window frame, enhancing the bending resistance of the car door at the window frame, and to a certain extent avoiding the phenomenon of shaking when the car door is opened and closed, thus improving the opening and closing quality of the car door.

[0047] The vehicle door and vehicle provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0048] refer to Figures 1 to 7 As shown, this embodiment provides a car door, including a door body 1 and a window frame 2.

[0049] For details, please refer to Figure 1 As shown, the door body 1 is provided with a window opening 3 to meet the needs of interior lighting, ventilation and visibility.

[0050] The door body 1 is usually equipped with a window glass (not shown). The window glass can be raised and lowered in the height direction of the vehicle body and is set at the window opening 3 in an openable manner.

[0051] refer to Figure 1 As shown, the window frame 2 is arranged circumferentially along the window opening 3 on one side of the door body 1 and connected to the door body 1, defining a closed cavity 4 between the window frame 2 and the door body 1. A reinforcing structure 5 is provided in the closed cavity 4, which is at least located around the corner of the window opening 3 and connected to at least one of the door body 1 and the window frame 2. The reinforcing structure 5 is capable of expansion to fill at least part of the gap between the door body 1 and the window frame 2.

[0052] In practice, the door body 1 and the window frame 2 can be connected together using clips, for example, to facilitate disassembly and replacement. Alternatively, the door body 1 and the window frame 2 can be glued together.

[0053] By providing a reinforcing structure 5 within the enclosed cavity 4 between the window frame 2 and the door body 1, the reinforcing structure 5 is connected to at least one of the door body 1 and the window frame 2. The reinforcing structure 5 can expand to fill at least part of the gap between the door body 1 and the window frame 2. In other words, after expansion, the reinforcing structure 5 abuts against both the door body 1 and the window frame 2, forming a stable filler between them. This provides structural support and reinforcement, improving the structural strength and rigidity of the door body 1 and the window frame 2 at weak points such as corners. This enhances the structural strength and lateral rigidity of the door at the window frame 2, thereby increasing the door's bending resistance at the window frame 2. To a certain extent, this prevents the door from shaking during opening and closing, improving the door's opening and closing quality.

[0054] After the reinforcing structure 5 expands, its outer wall surface becomes an abutment surface. The reinforcing structure 5 abuts against the door body 1 and window frame 2 through the abutment surface, which effectively enhances the rigidity and strength of the door body 1 and window frame 2.

[0055] In some implementations, the reinforcing structure 5 can be connected to the door body 1. In some implementations, the reinforcing structure 5 can also be connected to the window frame 2. Of course, in other implementations, the reinforcing structure 5 can be connected to both the door body 1 and the window frame 2.

[0056] In some implementations, the reinforcing structure 5 may expand upon completion of the connection. Specifically, the reinforcing structure 5 is connected to at least one of the door body 1 and the window frame 2, and the reinforcing structure 5 expands upon completion of the connection between the door body 1 and the window frame 2.

[0057] In other implementations, the reinforcing structure 5 may expand under a preset environment after the connection is completed. For example, the reinforcing structure 5 is connected to at least one of the door body 1 and the window frame 2, and the door body 1 and window frame 2 are connected; at this point, the reinforcing structure 5 does not expand. The door is then taken to the painting workshop, where at least the location of the reinforcing structure 5 is subjected to high-temperature heating. After being heated to the preset high temperature, the reinforcing structure 5 expands and solidifies upon cooling, remaining in the expanded state, thus maintaining the expanded state of the reinforcing structure 5 on the door.

[0058] After cooling and solidification, the reinforcing structure 5 remains in an expanded state and abuts against the door body 1 and the window frame 2 respectively. It plays a role in structural reinforcement and filling between the door body 1 and the window frame 2, thereby improving the structural strength and lateral stiffness of the door at the window frame 2.

[0059] In some implementations, during installation, the reinforcing structure 5 is installed inside the enclosed cavity 4. For example, the outer wall of the reinforcing structure 5 can be spaced apart from the inner wall of the door body 1, and the outer wall of the reinforcing structure 5 can be spaced apart from the inner wall of the window frame 2, which facilitates the installation of the reinforcing structure 5 inside the enclosed cavity 4.

[0060] In some implementations, the reinforcing structure 5 can be made of a material that expands when heated and solidifies when cooled, so that the reinforcing structure 5 expands when heated and can maintain its expanded state and structure after cooling.

[0061] The vehicle door provided in this embodiment consists of a door body 1 and a window frame 2. The window frame 2 is connected to one side of the door body 1 and arranged circumferentially along the window opening 3 on the door body 1. A closed cavity 4 is defined between the window frame 2 and the door body 1. A reinforcing structure 5 is provided within the closed cavity 4. The reinforcing structure 5 is at least located around the corner of the window opening 3, and the reinforcing structure 5 is capable of expansion to fill at least part of the gap between the door body 1 and the window frame 2. Because a reinforcing structure 5 is provided at the corner of the window opening 3 within the enclosed cavity 4, and the reinforcing structure 5 is connected to at least one of the door body 1 and the window frame 2, and because the reinforcing structure 5 expands to fill the gap between the door body 1 and the window frame 2 at the corresponding position, the reinforcing structure 5 expands to fill at least the part of the door body 1 and the window frame 2 at the corner of the window opening 3, forming a filler body. This structurally reinforces the weak position of the window frame and provides structural support between the door body 1 and the window frame 2, thereby improving the structural strength and rigidity of the door body 1 and the window frame 2. This improves the structural strength and lateral rigidity of the door at the window frame, enhances the bending resistance of the door at the window frame 2, and to a certain extent avoids the phenomenon of door shaking when opening and closing, thus improving the opening and closing quality of the door.

[0062] In some embodiments, reference Figures 2 to 6 As shown, the reinforcing structure 5 includes a frame 51 and a reinforcing member 52. The frame 51 is at least located at the corner of the window opening 3 and is connected to at least one of the door body 1 and the window frame 2. The reinforcing member 52 is connected to the frame 51 and can expand to fill at least part of the gap between the door body 1 and the window frame 2. After the reinforcing member 52 expands, its side away from the frame 51 abuts against the door body 1 and the window frame 2 respectively.

[0063] By making the reinforcing structure 5 include a frame 51 and a reinforcing member 52, and by connecting the reinforcing member 52 to the enclosed cavity 4 through the frame 51, assembly is convenient.

[0064] Meanwhile, by causing the reinforcing member 52 to expand, the reinforcing member 52 abuts against the door body 1 and the window frame 2 respectively after expansion, filling the closed cavity 4 as a structural filler, playing a structural support and reinforcement role, improving the connection strength and rigidity between the door body 1 and the window frame 2, and preventing the door body 1 and the window frame 2 from shaking during the opening and closing of the door.

[0065] In some implementations, the reinforcement 52 may be provided on the outside of the frame 51, for example.

[0066] In practice, after the reinforcing member 52 expands, the side of the reinforcing member 52 that faces away from the skeleton 51 is formed as an abutment surface for abutting against the cavity wall of the closed cavity 4.

[0067] In a specific implementation, the frame 51 can be, for example, a metal frame 51, which has good load-bearing capacity. For example, the frame 51 is an aluminum alloy frame.

[0068] In some implementations, the portions of the frame 51 on both sides along the length of the vehicle body that are exposed outside the reinforcement 52 abut against the cavity wall of the enclosed cavity 4, for example.

[0069] In some implementations, refer to Figure 6 As shown, the reinforcing member 52 includes a first sub-reinforcing part 521 and a second sub-reinforcing part 522. The first sub-reinforcing part 521 is provided on the side of the frame 51 facing the door body 1 along the width direction of the vehicle body, so as to expand and fill the gap between the frame 51 and the door body 1. The second sub-reinforcing part 522 is provided on the side of the frame 51 facing the window frame 2 along the width direction of the vehicle body, so as to expand and fill the gap between the frame 51 and the window frame 2.

[0070] In other words, the frame 51 is provided with a first sub-reinforcing part 521 and a second sub-reinforcing part 522, and the first sub-reinforcing part 521 and the second sub-reinforcing part 522 are respectively provided on both sides of the frame 51 along the width direction of the vehicle body. The first sub-reinforcing part 521 is located on the side of the frame 51 facing the door body 1, and the second sub-reinforcing part 522 is located on the side of the frame 51 facing the window frame 2. In this way, the reinforcing part 52 is provided on both sides of the frame 51 along the width direction of the vehicle body, which makes it easier for the reinforcing part 52 to fill the gap of the closed cavity 4 at the corresponding position, which helps to improve work efficiency.

[0071] After the first sub-reinforcing part 521 expands, it fills at least the gap between the frame 51 and the door body 1. After the second sub-reinforcing part 522 expands, it fills at least the gap between the frame 51 and the window frame 2. Thus, the closed cavity 4 can be filled relatively quickly, at least in the width direction of the vehicle body, which helps to improve work efficiency and product qualification rate.

[0072] In other embodiments, the reinforcement may be, for example, an annular reinforcement surrounding the outside of the frame.

[0073] In other implementations, the frame can abut against the window frame, or a reinforcing member can be provided on the side of the frame facing the door body, and the reinforcing member expands and abuts against the closed cavity.

[0074] In other implementations, the frame can abut against the door body, or a reinforcing member can be provided on the side of the frame facing the window frame, which expands and abuts against the closed cavity.

[0075] In some implementations, refer to Figure 2 , Figure 5 and Figure 6As shown, the skeleton 51 is a strip skeleton, and there are at least two first sub-reinforcing parts 521, which are spaced apart along the length of the strip skeleton.

[0076] By setting multiple first sub-reinforcing parts 521 between the frame 51 and the door body 1, and by setting the multiple first sub-reinforcing parts 521 at intervals along the length direction of the strip frame 51, the multiple first sub-reinforcing parts 521 can abut against the cavity wall of the closed cavity 4 from different positions, filling the gap between the frame 51 and the door body 1 to form multiple filling bodies, thereby further improving the structural strength and rigidity of the window frame 2 while meeting the lightweight design requirements.

[0077] In some embodiments, reference Figure 2 and Figure 5 As shown, the shape of the side of the first sub-reinforcing part 521 that is away from the frame 51 matches the shape of the inner wall of the door body 1, resulting in a good fit and a large contact area, which enhances the rigidity and strength of the door body 1.

[0078] In some implementations, refer to Figure 5 and Figure 6 As shown, there are at least two second sub-reinforcing parts 522, and at least two second sub-reinforcing parts 522 are spaced apart along the length direction of the strip frame.

[0079] By setting multiple second sub-reinforcing parts 522 between the frame 51 and the window frame 2, and by setting the multiple second sub-reinforcing parts 522 at intervals along the length direction of the strip frame 51, the multiple second sub-reinforcing parts 522 can abut against the cavity wall of the closed cavity 4 from different positions, filling the gap between the frame 51 and the window frame 2 to form multiple filling bodies, thereby further improving the structural strength and rigidity of the window frame 2 while meeting the design requirements of lightweighting.

[0080] In some embodiments, reference Figure 5 and Figure 6 As shown, the shape of the side of the second sub-reinforcing part 522 away from the frame 51 matches the shape of the inner wall of the window frame 2, resulting in a good fit and a large contact area, which enhances the rigidity and strength of the window frame 2.

[0081] In some implementations, the side of the first sub-reinforcing part 521 facing the frame 51 is connected to the side of the second sub-reinforcing part 522 facing the frame 51, that is, the first sub-reinforcing part 521 and the second sub-reinforcing part 522 are connected together, which improves the structural strength of the reinforcing member 52 after expansion, thereby further improving the structural strength and rigidity of the window frame 2.

[0082] Of course, a first sub-reinforcing part 521 can also be provided between the frame 51 and the door body 1. A second sub-reinforcing part 522 can also be provided between the frame 51 and the window frame 2.

[0083] In some embodiments, the reinforcing member 52 and the frame 51 can be integrally formed, resulting in good integrity and high structural strength.

[0084] Of course, the reinforcing member 52 and the frame 51 can be glued together, for example.

[0085] In some embodiments, the reinforcing member 52 may be, for example, an expanding rubber block.

[0086] The expanding rubber blocks can be, for example, polyurethane blocks, urethane blocks, expanding rubber strips, etc., which have good plastic deformation effects and can be relatively stable and firm against the door body 1 and window frame 2, with good filling and support effects.

[0087] In some embodiments, reference Figures 5 to 7 As shown, the frame 51 is provided with a first connecting part 6, and the door body 1 is provided with a second connecting part. The frame 51 is connected to the door body 1 through the cooperation of the first connecting part 6 and the second connecting part, which makes assembly convenient.

[0088] In practical implementation, one of the first connecting part 6 and the second connecting part includes a first latching protrusion, and the other of the first connecting part 6 and the second connecting part includes a first latching groove into which the first latching protrusion can extend. The structure is simple, easy to assemble, and the connection is firm and stable. At the same time, if either the reinforcing structure 5 or the door body 1 is damaged, only the two need to be disassembled and separated, and the damaged one needs to be replaced. It is not necessary to replace both the reinforcing structure 5 and the door body 1, which saves costs to a certain extent.

[0089] In some implementations, the first connecting part 6 may be a first latching protrusion provided on the frame 51, and the second connecting part may be a first latching groove provided on the door body 1.

[0090] In some other implementations, the first connecting part 6 may be a first slot provided on the frame 51, and the second connecting part may be a first protrusion provided on the door body 1.

[0091] In some embodiments, the frame 51 is provided with a third connecting part 7 and the window frame 2 is provided with a fourth connecting part. The frame 51 is connected to the window frame 2 through the cooperation of the third connecting part 7 and the fourth connecting part, which makes assembly convenient.

[0092] In practical implementation, one of the third connecting part 7 and the fourth connecting part includes a second latching protrusion, and the other of the third connecting part 7 and the fourth connecting part includes a second latching groove into which the second latching protrusion can extend. The structure is simple, easy to assemble, and the connection is firm and stable. At the same time, if either the reinforcing structure 5 or the window frame 2 is damaged, only the two need to be disassembled and separated, and the damaged one needs to be replaced. It is not necessary to replace both the reinforcing structure 5 and the window frame 2, which saves costs to a certain extent.

[0093] In some implementations, the third connecting part 7 may be a second latching protrusion provided on the frame 51, and the fourth connecting part may be a second latching groove provided on the window frame 2.

[0094] In some other implementations, the third connecting part 7 may be a second slot provided on the frame 51, and the fourth connecting part may be a second protrusion provided on the window frame 2.

[0095] In some implementations, refer to Figure 4 As shown, the shape of the reinforcing structure 5 after expansion matches the shape of the corresponding position of the closed cavity 4. This results in a good fit between the reinforcing structure 5 and the closed cavity 4, a large contact area, and a good enhancement effect on the stiffness and strength of the window frame 2.

[0096] In some embodiments, the outer wall of the reinforcing structure 5 is bonded to the cavity wall of the closed cavity 4. In this way, the reinforcing structure 5 not only abuts against the cavity wall of the closed cavity 4, but is also bonded to the cavity wall of the closed cavity 4, which improves the connection strength and structural stability of the reinforcing structure 5 in the closed cavity 4, thereby further enhancing the stiffness and strength of the window frame 2.

[0097] In some embodiments, the reinforcing structure 5 includes an expanding adhesive block, such as a polyurethane adhesive block, an urethane adhesive block, an expanding adhesive strip, etc.

[0098] Specifically, the reinforcing component 52 is an expanding rubber block.

[0099] After the reinforcing member 52 is connected to the closed cavity 4 through the skeleton 51, it expands after being heated at high temperature in the painting workshop to abut against the cavity wall of the closed cavity 4. After cooling and solidification, the reinforcing member 52 remains in abutting state with the closed cavity 4, and has high structural strength and stability. This fills the corresponding areas of the door body 1 and window frame 2, forming a highly stable and high-strength filling cavity, which plays a role in structural support and reinforcement.

[0100] At the same time, it is also integrated with the skeleton 51, further enhancing the structural strength and stability of the reinforced structure 5.

[0101] In some embodiments, there are at least two reinforcing structures 5. At least one reinforcing structure 5 is provided at the position of the body support pillar facing the front of the vehicle in the enclosed cavity 4, and at least one reinforcing structure 5 is provided at the position of the body support pillar facing the rear of the vehicle in the enclosed cavity 4.

[0102] In other words, the closed cavity 4 has at least one reinforcing structure 5 on the side facing the front of the vehicle. This reinforcing structure 5 corresponds to the body support column on the side of the door body 1 facing the front of the vehicle. In this way, while meeting the structural strength requirements, the size of the closed cavity 4 facing the front of the vehicle can be made smaller, which helps to expand the field of vision at the body support column.

[0103] For example, the door is the left front door of the vehicle. In the length direction of the vehicle body, the front side of the left front door is the A-pillar of the vehicle, and the rear side of the left front door is the B-pillar of the vehicle.

[0104] The enclosed cavity 4 has a front top corner and a front bottom corner on the side near the A-pillar, and the enclosed cavity 4 has a reinforcing structure at least at the front bottom corner on the side near the A-pillar.

[0105] The enclosed cavity 4 has a rear top corner and a rear bottom corner on the side near the B pillar, and the enclosed cavity 4 has a reinforcing structure at least at the rear bottom corner on the side near the B pillar.

[0106] In some embodiments, reference Figure 1 As shown, the door body 1 includes a connected inner door panel 11 and an outer door panel 12. A window opening 3 is provided on the inner door panel 11. A window frame 2 is connected to the side of the inner door panel 11 facing the outer door panel 12. A reinforcing structure 5 is provided between the inner door panel 11 and the window frame 2. The outer door panel 12 is located below the window frame 2.

[0107] In practice, a decorative element is usually provided on the side of the window frame 2 that is away from the inner door panel 11. The decorative element covers the window frame 2 and the inner door panel 11, which is aesthetically pleasing.

[0108] Among them, the decorative parts can be connected to at least one of the window frame 2 and the inner door panel 11.

[0109] Decorative parts can be made of plastic, for example.

[0110] This embodiment also provides a vehicle that includes a door.

[0111] Among them, the car door can be the left front door, right front door, left rear door, right rear door, etc.

[0112] The door in this embodiment has the same structure and implementation principle as the door provided in the above embodiments, and can bring the same or similar technical effects. It will not be described in detail here. For details, please refer to the description of the above embodiments.

[0113] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.
