Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a mating structure and a vehicle. Background Technology

[0002] Car doors are an important part of a car body, mainly used for drivers and passengers to get in and out of the car, while also serving functions such as protecting the safety of people inside the car, isolating them from the external environment (such as wind, rain, noise, and dust), and providing aesthetic decoration.

[0003] Existing car doors include a lower door panel body and a glove box cover located inside the lower door panel body. After the lower door panel body and the glove box cover are assembled, there is usually a gap between the edges of the lower door panel body and the edges of the glove box cover. This fitting structure with a gap between the edges of the lower door panel body and the glove box cover makes it difficult to guarantee the gap and surface difference at the mating parts of the edges, which is detrimental to improving the appearance quality of the car door. Utility Model Content

[0004] In view of this, this application aims to propose a mating structure that can better guarantee the gap and surface difference of the mating parts of the lower body of the door panel and the edge of the storage box baffle, thereby improving the appearance quality of the car door.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A matching structure is provided between the lower body of the door panel and the storage box baffle. The lower body of the door panel has a protrusion that protrudes towards the inside of the vehicle, and a storage box that is recessed towards the outside of the vehicle is provided in the middle of the protrusion. The mating structure includes multiple limiting units disposed on the lower body of the door panel. The multiple limiting units are arranged circumferentially around the protrusion. When the storage box baffle is assembled on the lower body of the door panel, each of the limiting units abuts against the flange on the storage box baffle.

[0006] Furthermore, each of the limiting units includes a boss provided on the protrusion and a limiting protrusion provided on the boss, and each of the limiting units abuts against the flange through the limiting protrusion. The protrusion is a hollow, thin-walled structure, and the boss is formed by a portion of the sidewall of the protrusion protruding away from the protrusion.

[0007] Furthermore, each of the aforementioned protrusions is provided with a guide portion, which guides the flange to slide to the outside of the guide portion; and / or, Each of the aforementioned bosses has multiple limiting protrusions, and each of the aforementioned limiting protrusions extends along the left-right direction of the entire vehicle.

[0008] Furthermore, the mating structure also includes multiple snap-fit ​​units, multiple first welding units, and multiple second welding units disposed between the lower body of the door panel and the storage box baffle; Multiple snap-fit ​​units are arranged circumferentially in the storage box, enabling the storage box baffle to be pre-installed on the lower body of the door panel; Multiple first welding units are arranged circumferentially at intervals on the protrusion, and multiple second welding units are arranged circumferentially at intervals on the miscellaneous box, which can weld the miscellaneous box baffle to the lower body of the door panel together.

[0009] Furthermore, each of the first welding units includes a first welding plate disposed on the protrusion, a support seat disposed on the miscellaneous box baffle, and a first welding column supported by the support seat; The first welding plate is provided with a first insertion hole, and the first welding column can be inserted into the first insertion hole and welded to the first welding plate.

[0010] Furthermore, the first welding column is provided with a limiting boss that protrudes outward along its own radial direction. The first welding column is inserted into the first insertion hole, and the edge of the first insertion hole blocks one side of the limiting boss, which can prevent the first welding column from coming out of the first insertion hole.

[0011] Furthermore, each of the support bases is provided with a plurality of first reinforcing ribs, which are arranged circumferentially around the first welded column and are offset from the limiting boss.

[0012] Furthermore, the support base has a cavity, and a second reinforcing rib is arranged within the cavity; and / or, The first welding plate has a plurality of first protrusions on at least one side, and the plurality of first protrusions are arranged circumferentially around the first insertion hole.

[0013] Furthermore, each of the second welding units includes a second welding plate disposed on the protrusion and a second welding column disposed on the miscellaneous box baffle; The second welding plate is provided with a second insertion hole, and the second welding column can be inserted into the second insertion hole and welded to the second welding plate; The second welding plate has a plurality of second protrusions on at least one side, and the plurality of second protrusions are arranged circumferentially around the second insertion hole; and / or, each of the second welding columns has a plurality of third reinforcing ribs circumferentially, and the plurality of third reinforcing ribs are arranged circumferentially around the second welding column.

[0014] Compared with related technologies, this application has the following advantages: (1) The mating structure described in this application provides more stable support for the flange by setting multiple limiting units on the lower body of the door panel and the protrusion abutting against the flange through the limiting units. This can better ensure the gap and surface difference between the two, thereby ensuring the mating accuracy between the lower body of the door panel and the storage box baffle, which is conducive to improving the appearance quality of the car door. The multiple limiting units are arranged circumferentially around the protrusion, which can better ensure the gap and surface difference between the lower body of the door panel and the storage box baffle in the circumferential direction of the lower body of the door panel, thereby improving the appearance quality of the car door.

[0015] (2) The limiting unit includes a boss on the protrusion and a limiting protrusion on the boss that can abut against the flange of the storage box baffle. This can further ensure the gap and surface difference between the lower body of the door panel and the storage box baffle. The protrusion is set as a hollow thin-walled structure. Compared with a solid structure, the hollow thin-walled structure can significantly reduce the amount of material used. Under the premise of ensuring the basic strength of the lower body of the door panel, its overall weight can be significantly reduced. The boss is formed by the local side wall of the protrusion protruding away from the protrusion. The boss formed in this way can play a role similar to a reinforcing rib, which can better improve the structural strength of the lower body of the door panel and use less material.

[0016] (3) The guide part provided on each boss can guide the flange to slide to the outside of the guide part, so that the protrusion can be quickly assembled into the area of ​​the flange enclosure, which can significantly improve the assembly efficiency between the lower body of the door panel and the storage box baffle; the limiting protrusion on each boss is set to multiple, which does not affect the smooth and efficient assembly of the boss into the area of ​​the flange enclosure. At the same time, each limiting protrusion extends along the left and right direction of the whole vehicle. This arrangement of extending along the left and right direction of the vehicle is also conducive to ensuring that the boss is smoothly and efficiently assembled into the area of ​​the flange enclosure.

[0017] (4) Simultaneously set up a snap-fit ​​unit, a first welding unit and a second welding unit. The snap-fit ​​unit can be used as a pre-positioning structure to pre-find the installation position of the storage box baffle on the lower body of the door panel. The first welding unit is arranged circumferentially at intervals on the protrusion, which can better ensure the connection structure strength between the lower body of the door panel and the edge of the storage box baffle. The second welding unit is arranged circumferentially at intervals on the storage box, which can better ensure the connection structure strength between the protrusion on the lower body of the door panel and the edge of the storage box baffle. With the two working together, the reliability of the connection between the lower body of the door panel and the storage box baffle is high, and it is conducive to ensuring the appearance quality after the two are assembled.

[0018] (5) The first welding unit includes a first welding plate, a support base and a first welding column, wherein the support base can provide a stable support foundation for the first welding column and facilitate the first welding plate and the first welding column to be welded together securely and reliably.

[0019] (6) The limiting boss provided on the first welding column can block one side of the limiting boss through the edge of the first insertion hole during the assembly of the lower body of the door panel and the storage box baffle, thereby preventing the first welding column from coming out of the first insertion hole. It can also play the role of pre-installing the storage box baffle on the lower body of the door panel, thus facilitating the welding of the first welding plate and the first welding column together. This structure occupies little space and is easy and quick to operate.

[0020] (7) Setting a first reinforcing rib on each support can better strengthen the structural strength of the first welded column, thereby improving the reliability of the connection between the lower body of the door panel and the storage box baffle.

[0021] (8) A cavity is provided inside the support base, so that the support base can be made with less material. At the same time, a second reinforcing rib is provided inside the cavity, which can better ensure the structural strength of the base while using less material, thereby improving the support strength of the first welded column. A first protrusion is provided on the first welding plate, which can provide more welding material when welding the first welding column and the first welding plate, which is beneficial to improving the strength and reliability of the welding of the first welding unit.

[0022] (9) The second protrusion provided on the second welding plate can provide more welding material when welding the second welding column and the second welding plate, which is conducive to improving the strength and reliability of the welding of the second welding unit. The third reinforcing rib provided can better improve the structural strength of the second welding column, thereby ensuring the reliability of the connection between the lower body of the door panel and the storage box baffle.

[0023] Another object of this application is to provide a vehicle whose doors are provided with the mating structure described above.

[0024] The vehicle described in this application, by applying the above-mentioned mating structure on the door, can better ensure the gap and surface difference between the lower body of the door panel and the storage box baffle, thereby ensuring the mating accuracy between the lower body of the door panel and the storage box baffle, and thus improving the appearance quality of the door.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0034] An embodiment of the first aspect of this application provides a mating structure disposed between the lower body of the door panel and the storage box baffle, which can better ensure the gap and surface difference between the two, thereby improving the appearance quality of the car door.

[0035] In related technologies, car doors are an important component of the car body, mainly used for drivers and passengers to get in and out of the car, while also serving functions such as protecting the safety of people inside the car, isolating them from the external environment (such as wind, rain, noise, and dust), and providing aesthetic decoration.

[0036] Existing car doors include a lower door panel body and a storage compartment cover located inside the lower door panel body. Due to the existing car door structure design, when the lower door panel body and the storage compartment cover are connected as one piece through a predetermined process, a gap will inevitably form at the joint of their edges.

[0037] During processing, factors such as manufacturing and assembly techniques can cause inconsistencies in controlling the gap between the edges of the two parts. Sometimes the gap is too wide, and sometimes there are areas where the fit is too tight, resulting in irregular gap shapes. Simultaneously, surface defects also become apparent. This unstable fit directly impacts the appearance quality of the door, hindering efforts to improve its overall aesthetics.

[0038] As an important component of a car body, the smoothness of the car door's surface and the uniformity of its gaps are crucial indicators of the overall vehicle's aesthetics. When observing a car door, irregular gaps and surface differences can ruin its overall appearance, giving the impression of rough workmanship and poor assembly, thereby reducing the user's satisfaction with the vehicle's quality.

[0039] In addition, the existing door panel lower body and the storage box baffle have problems such as large space occupation of the pre-clamping joint and poor welding strength between the two.

[0040] With the increasing demand for efficient use of interior space and higher requirements for interior quality, a more optimized design is needed to address these issues, thereby improving the functionality and overall aesthetics of the glove box.

[0041] To better address the gap and surface difference between the lower door panel body 1 and the storage box baffle 2, such as Figure 1 As shown, the mating structure provided in this embodiment is disposed between the lower body 1 of the door panel and the storage box baffle 2, as referenced. Figures 6 to 8As shown, the lower body 1 of the door panel has a protrusion 101 protruding towards the inside of the vehicle, and a storage box 102 recessed towards the outside of the vehicle is provided in the middle of the protrusion 101. Figure 2 and Figure 8 As shown, the edge of the storage box baffle 2 is provided with a flange 201 that folds outward to the side of the vehicle.

[0042] The mating structure of this embodiment includes multiple limiting units disposed on the lower body 1 of the door panel, and the multiple limiting units are arranged circumferentially around the protrusion 101. Specifically, when the storage box baffle 2 is assembled on the lower body 1 of the door panel, each limiting unit abuts against the flange 201.

[0043] It should be noted that, Figure 1 The diagram shows the lower structure of the vehicle door, specifically the structure of the left rear door. In simple terms, the door includes a lower door panel body 1 and a glove box cover 2 located inside the lower door panel body 1. Figure 1 This refers to the state in which the lower body 1 of the door panel and the storage box baffle 2 are assembled together.

[0044] The above-mentioned mating structure, by setting multiple limiting units on the lower body 1 of the door panel and making the limiting units abut against the flange 201 on the storage box baffle 2, can better ensure the gap and surface difference between the two, thereby ensuring the mating accuracy between the lower body 1 of the door panel and the storage box baffle 2, and thus improving the appearance quality of the door.

[0045] It should be noted that, in a preferred embodiment, the aforementioned limiting unit is provided at the front, rear and lower parts of the edge of the lower body 1 of the door panel, so as to better ensure the fitting accuracy between the lower body 1 of the door panel and the storage box baffle 2.

[0046] Furthermore, on the lower body 1 of the door panel, the larger opening on the door panel serves as a clearance hole for the speaker, and the glove box 102 and the clearance hole are arranged at intervals in the front-rear direction of the vehicle. On the glove box baffle 2, there are inlets and outlets corresponding to the glove box 102 for entering and exiting the glove box 102, and mounting holes corresponding to the clearance holes for mounting the speaker.

[0047] Combination Figure 9 and Figure 11 As shown, in some exemplary embodiments, each limiting unit includes a boss 103 provided on the protrusion 101 and a limiting protrusion 1031 provided on the boss 103. When the storage box baffle 2 is assembled on the lower body 1 of the door panel, each boss 103 abuts against the flange 201 through its own limiting protrusion 1031. The protrusion 101 is a hollow, thin-walled structure, and the boss 103 is formed by protruding from a partial sidewall of the protrusion 101 in a direction away from the protrusion 101.

[0048] The cooperation structure of this embodiment, by arranging multiple limiting units around the protrusion 101 in a circumferentially spaced manner, can better ensure the gap and surface difference between the lower body 1 of the door panel and the storage box baffle 2 in the circumferential direction, thereby helping to improve the appearance quality of the car door.

[0049] It should be noted that the protrusion 101 is formed by a portion of the lower body 1 of the door panel protruding towards the inside of the vehicle along the left-right direction of the whole vehicle, while the aforementioned storage box 102 is formed by the surface of the protrusion 101 facing the inside of the vehicle and recessing towards the outside of the vehicle.

[0050] In a preferred embodiment, a gap of 0.4mm-0.6mm is reserved between the outer surface of the boss 103 and the flange 201, such as 0.4mm, 0.5mm, or 0.6mm. The limiting protrusion 1031 acts like a reinforcing rib, improving the structural strength of the boss 103 and providing good support for the flange 201 through a close fit, thus ensuring that the gap difference between the storage box baffle 2 and the lower body 1 of the door panel is well controlled.

[0051] Here, the protrusion 101 is designed as a hollow thin-walled structure. Compared with a solid structure, the hollow thin-walled structure can significantly reduce the amount of material used. While ensuring the basic structural strength of the lower body 1 of the door panel, its overall weight can be significantly reduced. The boss 103 is formed by protruding from the local side wall of the protrusion 101 in a direction away from the protrusion 101. The boss 103 formed in this way can play a role similar to a reinforcing rib, which can effectively improve the structural strength of the lower body 1 of the door panel, and uses less material.

[0052] Continue to refer to Figure 7 and Figure 8 As shown, in some exemplary embodiments, each boss 103 is provided with a guide portion 1032, which can guide the flange 201 to slide to the outside of the guide portion 1032. Specifically, during the process of fastening and assembling the lower body 1 of the door panel and the glove box baffle 2 in the left-right direction of the vehicle, the guide portion 1032 provided on each boss 103 can guide the flange 201 to slide to the outside of the guide portion 1032, so that the protrusion 101 can be quickly assembled into the area enclosed by the flange 201, which can significantly improve the assembly efficiency between the lower body 1 of the door panel and the glove box baffle 2.

[0053] It should be noted that the outer side of the guide portion 1032 mentioned here refers to the side of the guide portion 1032 facing away from the center of the lower door panel body 1. For example, the outer side of the front guide portion 1032 of the lower door panel body 1 refers to the front side of the guide portion 1032, the outer side of the rear guide portion 1032 of the lower door panel body 1 refers to the rear side of the guide portion 1032, and the outer side of the lower guide portion 1032 of the lower door panel body 1 refers to the lower side of the guide portion 1032.

[0054] In detail, in the left-right direction of the whole vehicle, the guide part 1032 is located on the side of the boss 103 facing the inside of the vehicle. Specifically, it is an inclined surface provided on the boss 103, and along the left-right direction of the whole vehicle from the inside side to the outside side, the thickness of the boss 103 at the location where the guide part 1032 is provided gradually increases, so that when the glove box baffle 2 is assembled on the lower body 1 of the door panel, the boss 103 can be smoothly inserted into the area enclosed by the lower flange, the front flange and the rear flange of the glove box baffle 2.

[0055] After the glove box baffle 2 and the lower door panel body 1 are assembled together, the boss 103 located at the front of the lower door panel body 1 abuts against the front flange of the glove box baffle 2, the bosses 103 at the top and bottom of the lower door panel body 1 abut against the lower flange of the glove box baffle 2, and the boss 103 at the rear of the lower door panel body 1 abuts against the rear flange of the glove box baffle 2.

[0056] In a preferred embodiment, each boss 103 has multiple limiting protrusions 1031, and each limiting protrusion 1031 extends along the left-right direction of the vehicle. For example... Figure 8 In this design, there are two limiting protrusions 1031, which are arranged circumferentially on the boss 103 along the protrusion 101. This provides a good limiting effect on the flange 201 of the corresponding part. It should be understood that the number of limiting protrusions 1031 can also be one, three, four, etc.

[0057] In the example above, multiple limiting protrusions 1031 are set on each boss 103, which does not affect the smooth and efficient assembly of the boss 103 into the area enclosed by the flange 201. At the same time, each limiting protrusion 1031 extends along the left and right direction of the whole vehicle. This arrangement of extending along the left and right direction of the vehicle also helps to ensure that the boss 103 is smoothly and efficiently assembled into the area enclosed by the flange 201.

[0058] In some exemplary embodiments, the mating structure of this application further includes a plurality of snap-fit ​​units, a plurality of first welding units, and a plurality of second welding units disposed between the lower body 1 of the door panel and the storage box baffle 2.

[0059] Multiple snap-fit ​​units are arranged circumferentially on the storage box 102, which can pre-install the storage box baffle 2 on the lower body 1 of the door panel; multiple first welding units are arranged circumferentially on the protrusion 101, and multiple second welding units are arranged circumferentially on the storage box 102, which can weld the storage box baffle 2 to the lower body 1 of the door panel together.

[0060] In the above implementation, a snap-fit ​​unit, a first welding unit, and a second welding unit are simultaneously provided. The snap-fit ​​unit can serve as a pre-positioning structure to pre-locate the installation position of the miscellaneous box baffle 2 on the lower body 1 of the door panel.

[0061] It should be noted that, continue to refer to Figures 1 to 8 In this design, each latching unit includes a latching part 301 on the storage box baffle 2 and a latching hole 302 on the lower body 1 of the door panel. The latching part 301 and the latching hole 302 correspond one-to-one, and their structures can be based on those in the prior art.

[0062] Furthermore, the aforementioned first welding unit is arranged circumferentially at intervals on the protrusion 101, which can better ensure the structural strength of the connection between the lower body 1 of the door panel and the edge of the storage box baffle 2. The second welding unit is arranged circumferentially at intervals on the storage box 102, which can better ensure the structural strength of the connection between the protrusion 101 on the lower body 1 of the door panel and the edge of the storage box baffle 2. The combination of the two ensures high reliability of the connection between the lower body 1 of the door panel and the storage box baffle 2, and helps to ensure the appearance quality after the two are assembled.

[0063] Reference Figure 9 , Figure 10 and Figure 12 As shown, in some exemplary embodiments, each first welding unit includes a first welding plate 401 disposed on the protrusion 101, a support base 402 disposed on the miscellaneous box baffle 2, and a first welding post 403 supported by the support base 402. The first welding plate 401 is provided with a first insertion hole 4011, and the first welding post 403 can be inserted into the first insertion hole 4011 and welded to the first welding plate 401.

[0064] In detail, each of the first welding plates 401 is the bottom wall of a groove formed by a partial recess of the edge of the protrusion 101 towards the side away from the vehicle interior. The support base 402 and the first welding post 403 are located on the side of the glove box baffle 2 facing outwards from the vehicle. The first welding post 403 is mainly used for welding to the first welding plate 401. Since the distance between the lower body 1 of the door panel and the large surface of the glove box baffle 2 in the left-right direction of the vehicle is relatively large, the support base 402 is mainly used to support the first welding post 403 to ensure that the first welding post 403 can be welded together with the first welding plate 401.

[0065] In the above implementation, the first welding unit includes a first welding plate 401, a support base 402, and a first welding column 403. The support base 402 can provide a stable support foundation for the first welding column 403 and facilitates the stable and reliable welding of the first welding plate 401 and the first welding column 403 together.

[0066] Still refer to Figure 9 , Figure 10 and Figure 12 As shown, in some exemplary embodiments, the first welding post 403 is provided with a limiting boss 404 that protrudes outward along its own radial direction. The first welding post 403 is inserted into the first insertion hole 4011. The edge of the first insertion hole 4011 blocks one side of the limiting boss 404, which can prevent the first welding post 403 from coming out of the first insertion hole 4011.

[0067] In detail, the end of the limiting boss 404 that first inserts into the first insertion hole 4011 is provided with a guide slope to facilitate the smooth insertion of the first welding post 403 into the first insertion hole 4011. Then, the first welding plate 401 can be placed on the end of the limiting boss 404 away from its own guide slope to prevent the first welding post 403 from coming out of the first insertion hole 4011.

[0068] Here, the limiting boss 404 is set on the first welding column 403 as a pre-clamping structure for the storage box baffle 2 on the lower body 1 of the door panel. Compared with the existing separately set pre-clamping structure, it can save the arrangement space of the pre-clamping structure, increase the usable storage space of the storage box 102, and save the amount of materials and costs. This allows the storage box baffle 2 to be arranged more reasonably in the limited door panel space, thereby improving the space utilization rate.

[0069] It should be noted that, in a preferred embodiment, some of the first welding columns 403 are provided with limiting bosses 404, and the first welding columns 403 with limiting bosses 404 are arranged at intervals in the front, lower and rear parts of the lower body 1 of the door panel, so as to achieve a better pre-installation and positioning effect.

[0070] In the above implementation, the limiting boss 404 provided on the first welding column 403 can be blocked on one side of the limiting boss 404 by the edge of the first insertion hole 4011 during the assembly process of the lower body 1 of the door panel and the storage box baffle 2, thereby preventing the first welding column 403 from coming out of the first insertion hole 4011. This can serve to pre-install the storage box baffle 2 on the lower body 1 of the door panel, thereby facilitating the welding of the first welding plate 401 and the first welding column 403 together.

[0071] Reference Figure 2 and Figure 3As shown, in some exemplary embodiments, each support 402 is provided with a plurality of first reinforcing ribs 405, which are arranged circumferentially around the first welded column 403 and are offset from the limiting boss 404.

[0072] exist Figure 3 In the illustration, six first reinforcing ribs 405 are used as an example. Two of the first reinforcing ribs 405 extend and connect to the flange of the miscellaneous box baffle 2, two more first reinforcing ribs 405 are arranged on both sides of the welding column, and two more first reinforcing ribs 405 are flush with the front side of the support base 402. The arrangement of the six first reinforcing ribs 405 not only effectively supports the first welding column 403 and the opposite part, but also ensures the welding strength of the first welding column 403.

[0073] It should be understood that it is also feasible for the number of reinforcing ribs corresponding to each first welded column 403 to be other than six, such as three, four, seven, etc.

[0074] After the first welding post 403 is inserted into the first insertion hole 4011, the limiting boss 404 and each of the first reinforcing ribs 405 are placed on both sides of the first welding plate 401. Specifically, each of the first reinforcing ribs 405 is located on the side of the first welding plate 401 facing the inside of the vehicle, which can increase the support area, while the limiting boss 404 is located on the side of the first welding plate 401 facing the outside of the vehicle.

[0075] In the above implementation, the first reinforcing rib 405 is provided on each support 402, which can better strengthen the structural strength of the first welded column 403, thereby improving the reliability of the connection between the lower body 1 of the door panel and the storage box baffle 2.

[0076] like Figure 4 and Figure 5 As shown, in some exemplary embodiments, the support base 402 has a cavity 4021, and a second reinforcing rib 4022 is arranged within the cavity 4021. Specifically, each second reinforcing rib 4022 includes a transverse reinforcing rib 40221 and a longitudinal reinforcing rib 40222. The longitudinal reinforcing rib 40222 extends along the left-right direction of the vehicle, and transverse reinforcing ribs 40221 are provided on both sides of the longitudinal reinforcing rib 40222. Each side has two sets of transverse reinforcing ribs 40221 arranged at intervals along the left-right direction of the vehicle, thereby improving the structural strength of the support base 402.

[0077] In the above embodiment, a cavity 4021 is provided within the support base 402, allowing the support base 402 to be made with less material. Simultaneously, a second reinforcing rib 4022 is provided within the cavity 4021, which can better ensure the structural strength of the base while using less material, thereby improving the support strength for the first welded column 403. Furthermore, since the miscellaneous goods box baffle 2 is generally formed using injection molding, the second reinforcing rib 4022 in the above structure also facilitates smooth demolding after injection molding.

[0078] like Figure 6 and Figure 9 As shown, in some exemplary embodiments, the first welding plate 401 has a plurality of first protrusions 406 on the side facing away from the miscellaneous box baffle 2, and the plurality of first protrusions 406 are arranged circumferentially around the first insertion hole 4011.

[0079] In this embodiment, the first protrusion 406 on each first welding plate 401 is illustrated as six. It should be understood that other numbers of the first protrusion 406 on each first welding plate 401 are also possible, such as three, four, seven, etc.

[0080] Here, the first protrusion 406 provided on the side of the first welding plate 401 facing away from the miscellaneous box baffle 2 can provide more welding material when welding the first welding column 403 and the first welding plate 401, which is beneficial to improving the strength and reliability of the welding of the first welding unit. It should be understood that it is also feasible to provide the first protrusion 406 on the side of the first welding plate 401 facing the miscellaneous box baffle 2.

[0081] In some of the exemplary implementations, such as Figures 1 to 9 As shown, each second welding unit includes a second welding plate 501 disposed on the protrusion 101 and a second welding column 502 disposed on the miscellaneous box baffle 2.

[0082] In detail, the second welding plate 501 is provided with a second insertion hole 5011. After the lower body 1 of the door panel and the glove box baffle 2 are assembled together, the second welding post 502 can be inserted into the second insertion hole 5011 and welded to the second welding plate 501, thereby ensuring a stable and reliable connection between the side of the protrusion 101 facing the inside of the vehicle and the large surface of the glove box baffle 2.

[0083] In one example, the second welding plate 501 has a plurality of second protrusions 503 on the side facing away from the miscellaneous box baffle 2, and the plurality of second protrusions 503 are arranged circumferentially around the second insertion hole 5011.

[0084] In this embodiment, the second protrusions 503 on each second welding plate 501 are illustrated as six. It should be understood that other numbers of second protrusions 503 on each second welding plate 501 are also possible, such as three, four, seven, etc.

[0085] In the above embodiment, the second protrusion 503 provided on the side of the second welding plate 501 facing away from the miscellaneous box baffle 2 can provide more welding material when welding the second welding column 502 and the second welding plate 501, which is beneficial to improving the strength and reliability of the welding of the second welding unit. It should be understood that it is also possible to provide the second protrusion 503 on the side of the second welding plate 501 facing the miscellaneous box baffle 2.

[0086] In one example, each of the second welded pillars 502 is provided with a plurality of third reinforcing ribs 504 in the circumferential direction, and the plurality of third reinforcing ribs 504 are arranged at intervals in the circumferential direction of the second welded pillar. After the glove box baffle 2 and the lower body 1 of the door panel are assembled together, each of the third reinforcing ribs 504 is located on the side of the second welded plate 501 facing the inside of the vehicle.

[0087] In this embodiment, the third reinforcing rib 504 can effectively improve the structural strength of the second welded column 502, thereby ensuring the reliability of the connection between the lower body 1 of the door panel and the storage box baffle 2.

[0088] It is worth noting that, regarding the cooperation structure of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 9 shown.

[0089] The lower body 1 of the door panel has a protrusion 101 protruding towards the inside of the vehicle. The middle part of the protrusion 101 is provided with a storage box 102 recessed towards the outside of the vehicle. The edge of the storage box baffle 2 is provided with a flange 201 folded towards the outside of the vehicle. The mating structure includes multiple limiting units provided on the lower body 1 of the door panel. The multiple limiting units are arranged circumferentially around the protrusion 101.

[0090] Each limiting unit includes a boss 103 on the protrusion 101 and a limiting protrusion 1031 on the boss 103. When the storage box baffle 2 is assembled on the lower body 1 of the door panel, each boss 103 abuts against the flange 201 through its own limiting protrusion 1031. The protrusion 101 is a hollow, thin-walled structure, and the limiting protrusion 1031 is formed by protruding from a part of the sidewall of the boss 103 in a direction away from the protrusion 101.

[0091] The mating structure also includes multiple snap-fit ​​units, multiple first welding units, and multiple second welding units disposed between the lower body 1 of the door panel and the storage box baffle 2. The multiple snap-fit ​​units are arranged circumferentially around the storage box 102, enabling the storage box baffle 2 to be pre-installed on the lower body 1 of the door panel. The multiple first welding units are arranged circumferentially around the protrusion 101, and the multiple second welding units are arranged circumferentially around the storage box 102, enabling the storage box baffle 2 to be welded together with the lower body 1 of the door panel.

[0092] As in the preferred embodiment above, by including a boss 103 on the protrusion 101 and a limiting protrusion 1031 on the boss 103 that can abut against the upper flange 201 of the storage box baffle 2, the gap and surface difference between the lower body 1 of the door panel and the storage box baffle 2 can be better guaranteed, thereby improving the appearance quality of the door.

[0093] In addition, a snap-fit ​​unit, a first welding unit, and a second welding unit are provided. The snap-fit ​​unit can serve as a pre-positioning structure to pre-locate the installation position of the storage box baffle 2 on the lower body 1 of the door panel. The first welding unit is arranged circumferentially at intervals on the protrusion 101, which can better ensure the connection strength of the lower body 1 of the door panel and the edge of the storage box baffle 2. The second welding unit is arranged circumferentially at intervals on the storage box 102, which can better ensure the connection strength of the protrusion 101 on the lower body 1 of the door panel and the edge of the storage box baffle 2.

[0094] A second convenient embodiment of this application relates to a vehicle having the above-described mating structure on its doors.

[0095] The vehicle described in this application, by applying the above-mentioned mating structure on the door, can better ensure the gap and surface difference between the lower body of the door panel and the storage box baffle 2, thereby ensuring the mating accuracy between the lower body of the door panel 1 and the storage box baffle 2, and thus helping to improve the appearance quality of the door.
