[0028] Reference below Figure 1-Figure 3 A vehicle door assembly 100 according to an embodiment of a first aspect of the present invention will be described.

[0029] like Figure 1 As shown, the vehicle door assembly 100 includes an outer door panel 10 , an inner door panel 20 and a support assembly 30 .

[0030] The inner door panel 20 is connected to the inner side of the outer door panel 10. A portion of the inner door panel 20 is recessed toward the outer door panel 10, forming a receiving cavity 21 for accommodating the cart. The inner door panel 20 is provided with at least two fixing portions 22 for mounting a fixing rope. The at least two fixing portions 22 are located on different sides of the receiving cavity 21. A support assembly 30 is provided on the inner door panel 20 and is located on the lower sidewall of the receiving cavity 21. The support assembly 30 is used to support the bottom of the cart and is located below at least one fixing portion 22.

[0031] The outer door panel 10 is the outer structure of the vehicle door assembly 100. It can be used to protect the interior of the vehicle from the external environment.

[0032] The inner door panel 20 is connected to the inner side of the outer door panel 10 , and a portion of the inner door panel 20 is recessed toward the outer door panel 10 to form an accommodating cavity 21 for accommodating a cart.

[0033] This accommodating cavity 21 utilizes the space gap between the outer door panel 10 and the inner door panel 20 to facilitate passengers to store and fix larger items such as carts in the vehicle, thereby improving the utilization of the vehicle door space.

[0034] The shape and size of the accommodating cavity 21 can be adjusted according to needs and are not limited here.

[0035] In some optional embodiments, the outer door panel 10 can protrude outward from the vehicle. By designing the outer door panel 10 to protrude outward from the vehicle, an additional space is created on the basis of the original space of the vehicle door, and this additional space can further increase the storage capacity of the accommodating cavity 21.

[0036] In order to ensure that the cart and other items do not move or fall over during driving, a fixing portion 22 for installing a fixing rope is further provided on the inner door panel 20.

[0037] It is worth noting that the fixing rope can be an adjustable strap or elastic net bag, etc. These fixing devices are easy to operate and can adapt to items of different shapes and sizes while providing sufficient restraint.

[0038] In some optional embodiments, the strap may include a quick-release buckle or carabiner on one end and a slide adjuster on the other end, allowing the user to adjust the strap length and tension as needed, all with one hand.

[0039] Optionally, the elastic net bag includes a hook or a loop. These accessories can be connected to the inner door panel 20 to facilitate the user to release or fix items.

[0040] In some optional embodiments, the inner wall of the accommodating cavity 21 includes a buffer layer. The buffer layer can be, for example, foam or high-density sponge. The buffer layer can effectively prevent the object from colliding with the vehicle door during movement, protecting the object from damage and reducing noise.

[0041] To improve the stability and fixation of items such as the cart, a support assembly 30 is provided on the inner door panel 20. This support assembly 30 is carefully placed on the lower side wall of the accommodating cavity 21, and its position is just right to support the bottom of the cart, thereby effectively sharing the cart's weight and providing additional stability.

[0042] Specifically, the support assembly 30 is disposed in the lower side wall of the inner door panel 20. This arrangement ensures that the support assembly 30 does not hinder the smooth insertion and removal of the cart or other items, and is convenient for the user to quickly find and effectively utilize this support structure when loading the cart.

[0043] Optionally, the support assembly 30 can be set as one. This can meet the basic support requirements while reducing manufacturing costs. Alternatively, more than two support assemblies 30 can be set, and multiple support assemblies 30 are arranged in the horizontal direction. Figure 1, where transverse refers to the left-right direction. Providing multiple support assemblies 30 provides a larger support surface for the cart, thereby enhancing its stability and helping to prevent the cart from tipping over or sliding due to bumps or turns during travel. Furthermore, multiple support assemblies 30 can help disperse the pressure of the cart on a single support point, thereby reducing localized pressure on the door assembly 100 and helping to extend the service life of the vehicle's internal structure.

[0044] When there are multiple support assemblies 30 , the distance between adjacent support assemblies 30 can be adjusted according to needs and is not limited here.

[0045] In some optional embodiments, the support assembly 30 is detachably connected to the inner door panel 20. The detachable connection makes it easy to adjust or replace the support assembly 30.

[0046] The support assembly 30 is located below at least one of the fixing portions 22. This means that the support assembly 30 is positioned below the point where the stroller is attached to the fixing rope. This arrangement prevents interference between the support assembly 30 and the fixing strap, facilitating quick access and placement for the user. Furthermore, the combination of the support assembly 30 and the fixing portion 22 provides dual security for the stroller. The support assembly 30 provides physical support from below, while the fixing portion 22 provides restraint from above, jointly ensuring the stroller's stability during travel.

[0047] According to some embodiments of the vehicle door assembly 100 of the present invention, the fixing portion 22 is a fixing hole provided on the inner door panel 20 .

[0048] The fixing holes facilitate installation of the retaining rope. Workers can secure the retaining rope to the inner door panel 20 through the holes using fasteners such as bolts and nuts. The fixing holes make the installation process more intuitive and simple, thereby improving overall installation efficiency. Workers no longer need to perform complex adjustments and calibrations; they simply follow the pre-defined installation steps.

[0049] Combine Figure 1-Figure 2 There are three fixing parts 22, located on the upper side and left and right sides of the accommodating cavity 21. These three fixing holes are located on the upper side, left side, and right side of the accommodating cavity 21, forming three fixing positions. This layout not only takes into account the vertical support requirements of the cart, but also takes into account horizontal stability. The main function of the fixing holes is to serve as connection points for the fixing rope. By passing through these fixing holes, the fixing rope can be firmly fixed to the inner door panel 20, thereby providing the necessary support and restraint force for the cart, preventing the cart from falling or shifting due to bumps or sharp turns during driving.

[0050] In some optional embodiments, a section of fixing rope is provided between two fixing holes, and at least two sections of fixing rope are provided between three fixing holes.

[0051] Specifically, the securing rope consists of two sections: the first and second sections. The first section connects to the fixing holes on the upper and left sides, providing vertical and horizontal support for the stroller. The second section connects to the fixing holes on the upper and right sides, further strengthening the stroller's stability and preventing it from accidentally falling due to bumps or emergency maneuvers. The intersecting layout of the securing ropes also forms a more secure and reliable securing network.

[0052] According to the vehicle door assembly 100 of some embodiments of the present invention, a portion of the bottom wall of the accommodating cavity 21 abuts against the outer door panel 10 .

[0053] First, because the outer door panel 10, as a primary component of the vehicle door assembly 100, possesses high strength and rigidity. By directly abutting a portion of the bottom wall of the accommodating cavity 21 against the outer door panel 10, these properties of the outer door panel 10 are effectively utilized to enhance the supporting strength of the accommodating cavity 21. This means that when subjected to external forces, the accommodating cavity 21 is better able to resist deformation and damage, thereby protecting items such as carts secured within it from damage.

[0054] Secondly, this design also helps improve the overall durability of the door assembly 100. Because the bottom wall of the accommodating cavity 21 is additionally supported by the outer door panel 10, the door assembly 100 can maintain good shape stability and structural integrity even during long-term use. This helps reduce wear and damage caused by long-term use, extending the service life of the door assembly 100.

[0055] In some optional embodiments, a portion of the outer door panel 10 is configured to protrude toward the inner door panel 20 or form a certain supporting structure. These supporting structures can directly contact the bottom wall of the accommodating cavity 21 to provide additional supporting force therefor.

[0056] The support structure can be in the form of protrusions, ribs, etc., to ensure that sufficient support is provided without excessively increasing the weight or complexity of the vehicle door assembly 100. The shape and size of the support structure are compatible with the bottom wall of the accommodating cavity 21. In this way, the close contact between the support structure and the bottom wall of the accommodating cavity 21 can further improve the rigidity and stability of the accommodating cavity 21, thereby helping to resist external impact and vibration and protect accessories such as the cart from damage.

[0057] Optionally, the support structure can be firmly connected to the outer door panel 10 by bolts, welding, etc. These connection methods can ensure that the support platform will not loosen or fall off during long-term use, thereby maintaining its stable support effect.

[0058] According to the vehicle door assembly 100 of some embodiments of the present invention, a portion of the bottom wall of the accommodating cavity 21 protrudes in a direction away from the outer door panel 10 to form a reinforcing rib 211 .

[0059] The reinforcement ribs 211 enhance the rigidity of the bottom wall of the accommodating chamber 21 to a certain extent. This design effectively targets the critical stress-bearing areas of the accommodating chamber 21. This means that when external loads act on them, the reinforcement ribs 211 provide solid support, effectively preventing unnecessary deformation of the bottom wall and ensuring the stability and durability of the accommodating chamber 21 under pressure.

[0060] In the present application, the shape of the reinforcing ribs 211 can be highly flexible. For example, the reinforcing ribs 211 can be straight, curved, wavy, or cross-shaped, etc. Different shapes can adapt to different stress modes and space constraints. The specific shape can be selected based on actual needs and is not limited in this application.

[0061] In some optional embodiments, there is at least one reinforcing rib 211, and each reinforcing rib 211 is extended transversely, and its two ends are respectively connected to the opposite side walls of the accommodating cavity 21. Figure 2 , where the horizontal direction is the left-right direction in the figure.

[0062] In the above technical solution, the lateral extension of the reinforcing ribs 211 effectively increases the bending resistance of the bottom wall of the accommodating cavity 21. When external forces act on the accommodating cavity 21, the reinforcing ribs 211, like the supporting structure of a bridge, disperse and resist bending moments, thereby maintaining the straightness and stability of the bottom wall. Furthermore, the lateral extension of the reinforcing ribs 211 helps disperse stress from concentrated points to a wider area, reducing the risk of localized deformation or damage caused by stress concentration.

[0063] Moreover, the two ends of the reinforcing rib 211 are connected to the opposite side walls of the accommodating cavity 21, making the structure of the entire accommodating cavity 21 tighter and more stable, thereby effectively preventing the accommodating cavity 21 from lateral deformation when subjected to external pressure.

[0064] Therefore, by providing the reinforcing ribs 211 in this way, it is helpful not only to enhance the rigidity of the bottom wall, but also to improve the torsional resistance and stability of the entire accommodating cavity 21 .

[0065] In some Figure 2 In the embodiment shown, there are two reinforcing ribs 211, which are arranged at intervals along the vertical direction of the accommodating cavity 21. Figure 2 The reinforcing ribs 211 can enhance the strength and rigidity of the accommodating cavity 21 in the upper and lower positions to prevent it from being deformed or damaged when subjected to external forces.

[0066] According to some embodiments of the present invention, the vehicle door assembly 100 is as follows: Figure 2 As shown, the support assembly 30 includes: a connecting member 31, which is connected to the lower side wall of the accommodating cavity 21, and the connecting member 31 is extended laterally. A portion of the connecting member 31 protrudes in a direction away from the outer door panel 10 to form a connecting protrusion 32.

[0067] The connecting member 31 is connected to the lower side wall of the accommodating cavity 21 and serves as an additional structural reinforcement element to enhance the supporting stability of the supporting component 30 and further improve the reliability of the vehicle door assembly 100.

[0068] Optionally, combined Figure 2-Figure 3 The connecting protrusion 32 includes a connecting section 321 and two bent sections 322. The connecting section 321 is provided with a connecting bolt, and the thread of the connecting bolt is located on the side of the connecting section 321 away from the outer door panel 10. The two bent sections 322 are connected to the connecting section 321 on both sides of the lateral direction, and each bent section 322 is bent relative to the connecting section 321 toward the outer door panel 10.

[0069] The connecting section 321 of the connecting protrusion 32 is directly connected to the lower sidewall of the accommodating cavity 21, acting as a bridge. Connecting bolts are provided on the connecting section 321 to secure the connecting protrusion 32 to the inner door panel 20. Notably, the threaded portion of the connecting bolt is located on the side of the connecting section 321 facing away from the outer door panel 10, providing a threaded connection point for the support assembly 30.

[0070] The connecting protrusion 32 also includes two bent sections 322, which are connected to the connecting section 321 on either side. These two bent sections 322 are bent relative to the connecting section 321 toward the outer door panel 10. This increases the contact area between the connecting protrusion 32 and the internal structure of the vehicle door, improving the stability of the connection. It also allows the connecting protrusion 32 to better adapt to the complex spatial layout of the vehicle door interior and avoid interference with other components.

[0071] The connection protrusion 32, through the combination of the connecting section 321 and the bent section 322, strengthens the connection between the connector 31 and the lower sidewall of the accommodating cavity 21. This allows the connector 31 to be more stably fixed in place when subjected to external forces, reducing the risk of door deformation or damage caused by loose connections. The bent section 322 also allows the connection protrusion 32 to better adapt to the complex spatial layout of the door interior. This not only improves the door's appearance and neatness, but also allows for a more compact arrangement of the various internal components, enhancing the door's overall performance and reliability.

[0072] Furthermore, the connecting bolt design on the connecting protrusion 32 simplifies and facilitates installation and maintenance. The bolts securely fasten the connecting protrusion 32 to the vehicle door without the need for complex welding or riveting. Furthermore, if the connecting protrusion 32 needs to be replaced or repaired, it can be easily removed by simply removing the bolts.

[0073] The connecting bolts are projection-welded to the inner door panel 20, which helps to achieve a firm connection between the connecting piece 31 and the inner door panel 20. This projection welding connection method not only has high strength and durability, but also can effectively resist various forces and pressures that the door may encounter during use.

[0074] In such Figure 2 and Figure 3 In the embodiment shown, the connecting member 31 includes: two connecting protrusions 32 arranged in the transverse direction, and the bending section 322 between the two connecting protrusions 32 is connected. Figure 2 Left and right direction in .

[0075] This arrangement provides a wide and thick base for the connecting member 31, so that when subjected to vertical loads, the two connecting protrusions 32 can share the pressure, thereby effectively dispersing and resisting the vertical force. This horizontal layout helps to provide uniform support and greater load-bearing capacity.

[0076] The bent section 322 between the two connecting protrusions 32 is connected. This structure not only strengthens the structural connection between the connecting protrusions 32, but also increases the overall rigidity and stability of the connector 31. The bent section 322 may connect the two protrusions at a certain angle or curve. This design helps absorb and distribute stress, preventing sudden breakage or deformation of the connector when subjected to external forces.

[0077] Optionally, the two connecting protrusions 32 are an integral piece.

[0078] According to some embodiments of the present invention, the vehicle door assembly 100 is as follows: Figure 3 As shown, the connecting member 31 includes: at least two connecting buckles 33 , and the connecting member 31 is welded to the inner door panel 20 on both lateral sides of each connecting buckle 33 .

[0079] The two lateral sides of each connecting buckle 33 are tightly connected to the inner door panel 20 by welding. This welding connection method further ensures the firm connection between the connecting piece 31 and the inner door panel 20.

[0080] The connecting buckle 33 is welded to both sides of the connector 31. This connection method helps distribute the vertical force applied to the connecting buckle 33 over a wider area. When the connector 31 is subjected to vertical forces, the welds on both sides of the connecting buckle 33 can jointly withstand these forces, reducing the risk of single-point stress and improving the durability of the vehicle door assembly 100.

[0081] Optionally, the door assembly 100 further includes a positioning assembly 40, see Figure 3 The positioning assembly 40 includes: a positioning column (not shown) and a positioning hole 41, wherein the positioning column is provided on one of the inner door panel 20 and the connecting member 31, and the positioning hole 41 is provided on the other of the inner door panel 20 and the connecting member 31.

[0082] The function of the positioning assembly 40 is to ensure precise alignment between the connector 31 and the inner door panel 20. By cooperating with the positioning post and the positioning hole 41, the installation position of the connector 31 on the inner door panel 20 can be quickly and accurately determined, avoiding installation difficulties or structural instability caused by position deviation.

[0083] In addition to precise alignment, the positioning assembly 40 also provides a certain degree of connection stability. When the positioning post is fully inserted into the positioning hole 41, the tight fit formed therebetween effectively prevents the connector 31 from loosening or shifting during use, thereby ensuring the overall stability and safety of the door structure.

[0084] The design of the positioning assembly 40 also simplifies the installation process of the vehicle door assembly 100. Workers can easily install the connector 31 on the inner door panel 20 based on the fit between the positioning post and the positioning hole 41, eliminating the need for complex measurement and marking. This helps improve installation efficiency and reduce the error rate during the installation process.

[0085] Optionally, the shape and size of the positioning hole 41 match those of the positioning post, so as to ensure that when the positioning post is inserted into the positioning hole 41 , the two can fit tightly together to form a stable connection.

[0086] In some specific embodiments, such as Figure 3 As shown, the positioning column is provided on the inner door panel 20, and the positioning hole 41 is provided on the connecting piece.

[0087] The vehicle according to the embodiment of the second aspect of the present invention includes: the door assembly 100 according to the embodiment of the first aspect of the present invention.

[0088] It is worth noting that the specific type of vehicle referred to in this application is not limited. For example, the vehicle can be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle, a fuel cell electric vehicle, an extended-range vehicle, a solar electric vehicle, a gas fuel vehicle (such as a hydrogen engine vehicle), or a biofuel vehicle (such as a vehicle powered by ethanol, biodiesel, etc.). The vehicle of the embodiment of the present utility model utilizes the improved door assembly 100, and by combining the accommodating cavity 21 and the support assembly 30, achieves efficient utilization of the interior space of the door, thereby improving the space utilization rate of the vehicle interior.
