Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a vehicle-mounted ladder assembly and vehicle. Background Technology

[0002] As people's living standards improve, self-driving tours are becoming increasingly popular. When driving outdoors, people sometimes climb onto the roof of vehicles with walkways to get a better view.

[0003] To facilitate access to the roof, some vehicle models can be equipped with ladders via optional features. In traditional designs, ladders are typically mounted on the side panels of the vehicle, with support structures integrated into these panels to enhance installation reliability. However, existing ladder installation methods still suffer from limitations, such as the limited strength of the ladder within the vehicle body, which hinders the improvement of the installation and usability of ladders on vehicles. Utility Model Content

[0004] In view of this, this application aims to provide a vehicle-mounted ladder assembly to improve the installation and use quality of vehicle ladders.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A vehicle-mounted ladder assembly includes a ladder and a mounting structure adapted to mount the ladder on a vehicle body via mounting members, wherein the mounting structures are respectively provided at the top and bottom of the ladder; The mounting structure includes a mounting seat and a mounting bracket disposed between the side pillar and the outer side panel in the vehicle body; The mounting base is fixed to the side column by the mounting bracket, and the mounting base is provided with a ladder mounting hole. The mounting component passes through the mounting hole on the outer side plate and is fixed in the ladder mounting hole.

[0006] Furthermore, the mounting base is cast and the mounting bracket is stamped. The mounting base has an internal cavity, and a cavity is formed between the mounting bracket and the side column.

[0007] Furthermore, the mounting base has a blocking plate at one end near the outer side panel to seal the cavity, and the ladder mounting hole is provided through the blocking plate; The blocking plate is attached to the inner wall of the outer side panel, and a sealant is provided between the blocking plate and the inner wall of the outer side panel.

[0008] Furthermore, the mounting base is provided with a bracket connection hole, and the mounting base and the mounting bracket are fixedly connected together by a connector; The connector passes through the connection hole on the mounting bracket and is fixed in the bracket connection hole.

[0009] Furthermore, the mounting base is provided with a plurality of bracket connection holes and a plurality of ladder mounting holes, and at least some of the bracket connection holes and ladder mounting holes are coaxially arranged; The mounting base is provided with a partition structure, which separates the coaxially arranged bracket connection hole and ladder mounting hole.

[0010] Furthermore, the mounting bracket has a bracket body and a plurality of support arms connected to the bracket body, the support arms being connected to the side column, and at least the bracket body having the connection through hole; and / or, The mounting base has a housing and a mounting column disposed within the housing by means of reinforcing ribs. The ladder mounting hole and the bracket connection hole are disposed on the mounting column.

[0011] Furthermore, the mounting structure includes a mounting bracket disposed on the outer side of the side panel; The mounting bracket is arranged corresponding to the mounting seat, and the mounting component passes through the through hole on the mounting bracket. The installed ladder is supported on the mounting bracket.

[0012] Furthermore, one end of the mounting bracket near the outer side panel is attached to the outer wall of the outer side panel, and a sealing gasket is provided between the mounting bracket and the outer side panel.

[0013] Furthermore, the ladder includes vertical bars on both sides and multiple horizontal bars connecting the vertical bars on both sides, wherein the diameter of the horizontal bars is smaller than that of the vertical bars, and the ends of the horizontal bars are embedded in the vertical bars; and / or, The ladder is mounted at the rear of the vehicle body via the mounting structure.

[0014] Compared with related technologies, this application has the following advantages: (1) The vehicle ladder assembly described in this application is mounted to the vehicle body by means of the top and bottom of the ladder respectively by means of the mounting structure, and the mounting structure includes a mounting seat and a mounting bracket located between the side panel and the side pillar. The mounting seat is fixed to the side pillar by means of the mounting bracket. The mounting seat can be fixed to the side pillar, and the overall structural strength of the ladder mounting position can be increased by means of the side pillar. This can improve the installation strength of the ladder on the vehicle body, improve the reliability of the ladder, and thus improve the installation and use quality of the ladder on the vehicle.

[0015] (2) The mounting base is cast and formed into a cavity, which facilitates the preparation of the mounting base and helps to reduce the cost of the mounting base. At the same time, the mounting base is a cast and formed cavity, which gives the mounting base itself good structural strength. Combined with the fixing of the mounting base to the side column, it can better increase the overall structural strength of the ladder installation position, improve the installation strength of the ladder on the vehicle body, and improve the reliability of the ladder. The mounting bracket is stamped and formed into a cavity between the mounting bracket and the side column. The stamping of the mounting bracket can facilitate its design and preparation, which helps to reduce the design and manufacturing cost of the installation structure. At the same time, the high structural strength of the cavity can be used to increase the structural strength of the mounting bracket itself, which helps to further improve the stability of the mounting base fixed on the side column.

[0016] (3) A blocking plate is provided at one end of the mounting base near the outer side panel, and the blocking plate is fitted to the inner wall of the outer side panel. A sealant is provided between the blocking plate and the inner wall of the outer side panel. The mounting base is designed to conform to the shape of the outer side panel, so that the mounting base can provide better support for the outer side panel. This can effectively prevent the outer side panel from collapsing during ladder installation, which helps to ensure the appearance quality of the vehicle body. At the same time, the sealant provided between the blocking plate and the inner wall of the outer side panel can also effectively seal the gap between the mounting base and the outer side panel, preventing external water from entering the vehicle body side panel through the installation holes on the outer side panel, which is beneficial to improving the sealing of the ladder installation position.

[0017] (4) A bracket connection hole is provided on the mounting base, and a connection through hole is provided on the mounting bracket. The mounting bracket and the mounting base are connected together by a connector that passes through the connection through hole and is fixed in the bracket connection hole. The structure is simple, easy to design, form and connect. It can facilitate the connection between the mounting base and the mounting bracket, and also help to ensure the reliability of the connection between the mounting bracket and the mounting base.

[0018] (5) The mounting base has multiple bracket connection holes and ladder mounting holes, and some bracket connection holes and ladder mounting holes are coaxially arranged. A partition structure is provided in the mounting base to separate the coaxial bracket connection holes and ladder mounting holes. On the one hand, the coaxial arrangement of the bracket connection holes and ladder mounting holes simplifies the structure of the mounting base and facilitates the design and preparation of the mounting base. On the other hand, the partition structure separates the bracket connection holes and ladder mounting holes, and on the basis of the coaxial arrangement of the bracket connection holes and ladder mounting holes, it can prevent external water from entering the interior of the vehicle side panel through the ladder mounting holes and bracket connection holes, thereby improving the sealing of the ladder mounting position.

[0019] (6) The mounting bracket has a main body and multiple arms, and each arm is connected to the side column. At the same time, at least multiple bracket connection holes are provided on the main body of the bracket. This not only facilitates the connection between the mounting base and the mounting bracket, as well as between the mounting bracket and the side column, but also facilitates the formation of a cavity between the mounting bracket and the side column. Furthermore, by connecting the mounting base to the main body of the bracket and the arms respectively, the reliability of the connection between the mounting bracket and the mounting base can be guaranteed, which helps to improve the stability of the mounting base fixed on the side column.

[0020] The mounting base has a shell and a mounting post set inside the shell via a reinforcing rib. The ladder mounting hole and the bracket connection hole are set on the mounting post. This allows the mounting base to be a cast hollow part, giving the mounting base itself good structural strength. It also facilitates the setting of the ladder mounting hole and the bracket connection hole on the mounting post.

[0021] (7) A mounting bracket corresponding to the mounting seat arrangement is provided on the outer side of the side panel, so that the mounting parts are inserted into the through holes on the mounting bracket, and the ladder after installation is supported on the mounting bracket. With the support of the mounting bracket on the inner side of the side panel, the ladder after installation is supported on the outer side of the side panel, so that there is a certain distance between the ladder and the side panel of the vehicle body. This facilitates the use of the ladder, improves the practicality of the ladder, and also helps to avoid bumping the side panel of the vehicle body when using the ladder, which would damage the appearance of the vehicle and improve the quality of the ladder.

[0022] (8) By making the end of the mounting bracket close to the outer wall of the side panel fit against the outer wall of the side panel, and setting a sealing gasket between the mounting bracket and the side panel, the end of the mounting bracket can be designed to conform to the shape of the side panel, avoiding problems such as collapse of the side panel during ladder installation and use due to the stress on the mounting bracket, which helps to ensure the appearance quality of the vehicle body. At the same time, the sealing gasket set between the mounting bracket and the side panel can also prevent external water from flowing into the side panel of the vehicle body through the gap between the mounting bracket and the side panel and the installation through hole on the side panel, which is beneficial to improving the sealing of the ladder installation position.

[0023] (9) The ladder includes vertical bars on both sides and multiple horizontal bars connected between the vertical bars on both sides, and the diameter of the horizontal bars is smaller than that of the vertical bars, and the ends of the horizontal bars are embedded in the vertical bars. This facilitates the design and manufacture of the ladder, and also helps to ensure the connection strength between the horizontal bars and the vertical bars, ensure the stability of the overall structure of the ladder, and improve the appearance quality of the ladder.

[0024] The ladder is installed at the rear of the vehicle body via a mounting structure. This avoids the problems associated with installing a ladder on the side of the vehicle body, which would increase the overall width of the vehicle, affect its passability, and increase wind noise during driving, thus negatively impacting the overall driving and riding comfort. It allows users to easily access the roof while ensuring the overall quality of the vehicle's use.

[0025] Another object of this application is to provide a vehicle having an onboard ladder assembly as described above.

[0026] The vehicle described in this application has the same advantages as the aforementioned vehicle-mounted ladder assembly compared to related technologies, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0028] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0030] Furthermore, it should be noted that in the description of this application, if terms such as "upper," "lower," "inner," or "outer" appear, indicating orientation or positional relationship, these are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0032] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. 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] The first aspect of this application provides a vehicle-mounted ladder assembly, which is mounted on the vehicle body via a mounting member 5, and preferably on the rear of the vehicle body. The vehicle-mounted ladder assembly of this embodiment, through its innovative structural design, is beneficial to improving the installation and use quality of the vehicle ladder 1.

[0035] In related technologies, some vehicle models, especially off-road vehicles, can have a ladder 1 installed on the vehicle body as an option to allow users to access the roof. For vehicles equipped with a ladder, in traditional body designs, the ladder 1 is generally installed on the side panel of the vehicle body by bolts, and a bracket structure is also set in the side panel of the vehicle body. The bolts for installing the ladder 1 are connected to the bracket structure to increase the reliability of the ladder 1 installation.

[0036] However, although the existing ladder installation method can achieve the installation of ladder 1 on the vehicle body, it still has shortcomings such as limited installation strength of ladder 1 on the vehicle body, which is not conducive to improving the installation and use quality of ladder 1 on the vehicle.

[0037] In view of this, in order to overcome the shortcomings of the related technology, the vehicle-mounted ladder assembly in this embodiment combines... Figures 1 to 22 As shown, the overall design includes a ladder 1 and a mounting structure 4 suitable for mounting the ladder 1 on the vehicle body via a mounting member 5, and mounting structures 4 are respectively provided at the top and bottom of the ladder 1.

[0038] The mounting structure 4 includes a mounting base 401 and a mounting bracket 402 disposed between the side pillar 3 and the outer side panel 2 in the vehicle body. The mounting base 401 is fixed to the side pillar 3 by the mounting bracket 402, and a ladder mounting hole 401a is provided on the mounting base 401. The mounting component 5 passes through the mounting through hole 201 on the outer side panel 2 and is fixed in the ladder mounting hole 401a to realize the installation of the ladder 1 on the vehicle body.

[0039] Therefore, as described above, by mounting the top and bottom of the ladder 1 to the vehicle body via the mounting structure 4, and by including a mounting seat 401 and a mounting bracket 402 located between the side panel 2 and the side pillar 3, with the mounting seat 401 fixed to the side pillar 3 via the mounting bracket 402, this embodiment can utilize the fixing of the mounting seat 401 to the side pillar 3 to increase the overall structural strength of the ladder 1 mounting position, thereby improving the installation strength of the ladder 1 on the vehicle body and the reliability of the ladder 1, thus achieving the effect of improving the installation and use quality of the ladder 1 on the vehicle.

[0040] Based on the above overview, it is worth noting that, specifically, in some of the exemplary implementations, the following still applies: Figures 1 to 3 As shown in the figure, the ladder 1 in this embodiment is preferably installed at the rear of the vehicle body via the mounting structure 4.

[0041] In this way, compared to installing the ladder 1 on the side of the vehicle body, placing the ladder 1 at the rear of the vehicle body can obviously help users climb onto the roof while avoiding the increase in vehicle width caused by installing the ladder 1 on the side of the vehicle body, which would affect the vehicle's passability and increase wind noise during vehicle operation, thus adversely affecting the overall driving and riding comfort.

[0042] Furthermore, since the ladder 1 is installed at the rear of the vehicle body, and considering that the ladder 1 is generally installed on vehicles with a D-pillar, such as SUVs, this embodiment still refers to... Figures 1 to 3 As shown, the aforementioned side pillar 3 can typically be a D-pillar in the side of the vehicle body. That is, in the preferred embodiment of this example, the ladder 1 is installed on the D-pillar in the side of the vehicle body via the mounting structure 4, and specifically installed on the rear side of the D-pillar.

[0043] It should be noted that, in addition to the above-mentioned installation of the ladder 1 at the rear of the vehicle body and on the D-pillar in the side panel of the vehicle body, in other embodiments, if the corresponding installation conditions are met, the ladder 1 can also be installed in other positions on the vehicle body, such as the side panel of the vehicle body. In addition to installation on the D-pillar in the side panel of the vehicle body, the ladder 1 can also be installed on other column structures in the side panel of the vehicle body using the ladder installation structure of this embodiment, as long as the column structure meets the arrangement requirements of the ladder installation structure of this embodiment, and there are no restrictions on this.

[0044] In addition, since this embodiment provides mounting structures 4 for the top and bottom of the ladder 1 respectively, for ease of description, the relevant structure for mounting at the top of the ladder 1 can be called the upper mounting structure 4a, and similarly, the relevant structure for mounting at the bottom of the ladder 1 can be called the lower mounting structure 4b.

[0045] In this embodiment, the upper mounting structure 4a and the lower mounting structure 4b can generally adopt the same or substantially the same structural form to reduce the design, fabrication, and assembly costs of the mounting structure 4. Furthermore, this embodiment will specifically illustrate this by using the example of the upper mounting structure 4a and the lower mounting structure 4b having substantially the same structure.

[0046] Of course, in addition to making the upper mounting structure 4a and the lower mounting structure 4b have the same or basically the same structure, making the upper mounting structure 4a and the lower mounting structure 4b have similar structures, or making the upper mounting structure 4a and the lower mounting structure 4b have different structures, it is also possible, and there is no restriction on it here, as long as the ladder 1 can be reliably installed on the vehicle body through the upper mounting structure 4a and the lower mounting structure 4b.

[0047] In this embodiment, since the upper mounting structure 4a and the lower mounting structure 4b are basically the same, the upper mounting structure 4a will be used as an example to introduce the mounting structure 4 in detail.

[0048] In detail, by Figure 5 , Figure 6 and continue to combine Figures 7 to 14 As shown, in some exemplary embodiments, the mounting base 401 may be cast and the mounting bracket 402 may be stamped. Simultaneously, a cavity S is formed inside the mounting base 401, and a cavity Q is formed between the mounting bracket 402 and the side column 3.

[0049] This allows the mounting base 401 to be cast and formed into a cavity S inside, which facilitates the preparation of the mounting base 401, helps reduce its cost, and also allows the mounting base 401 to have good structural strength due to its cast cavity. Combined with the fixing of the mounting base 401 to the side pillar 3, it can better increase the overall structural strength of the ladder 1 installation position, improve the installation strength of the ladder 1 on the vehicle body, and improve the reliability of the ladder 1 in use.

[0050] The stamping process of the mounting bracket 402, which forms a cavity Q between it and the side column 3, facilitates its design and fabrication, thus reducing the design and manufacturing costs of the mounting structure 4. Simultaneously, the high structural strength of the cavity increases the structural strength of the mounting bracket 402, further enhancing the stability of the mounting base 401 fixed to the side column 3.

[0051] In this embodiment, it is worth noting that the cast mounting base 401 can generally be made of aluminum alloy or magnesium alloy. This not only facilitates the preparation of the mounting base 401 and gives it better structural strength, but also makes the mounting base 401 lighter, which is beneficial for achieving lightweight design.

[0052] Additionally, in some exemplary embodiments, based on the casting of the mounting base 401, as a structural example, it may structurally have a housing 4011 and a mounting post 4013 disposed within the housing 4011 by a reinforcing rib 4014. The aforementioned ladder mounting hole 401a is disposed on the mounting post 4013.

[0053] Thus, the mounting seat 401 is provided with a housing 4011 and mounting posts 4013 disposed inside the housing 4011 via reinforcing rib plates 4014, so that a cavity S inside the mounting seat 401 can be formed, making the mounting seat 401 a cast molded hollow part. By taking advantage of the high structural strength of the hollow part structure, the structural strength of the mounting seat 401 itself is improved.

[0054] In some exemplary embodiments, the above-mentioned reinforcing rib plates 4014 located inside the mounting seat 401 may, for example, be in a "meter" shape, and form a plurality of support plates 40141 arranged around the mounting posts 4013.

[0055] In this way, by making the reinforcing rib plates 4014 in a "meter" shape and forming a plurality of support plates 40141 arranged around the mounting posts 4013, it can be understood that this not only enables the reinforcing rib plates 4014 to have a relatively regular overall structure, which facilitates the design and manufacture of the reinforcing rib plates 4014 and even the mounting seat 401, but also can utilize the connection support of each support plate 40141 to the mounting posts 4013 at different angles to ensure the connection and reinforcement effect of the reinforcing rib plates 4014, which helps to improve the reliability of the mounting posts 4013 arranged inside the mounting seat 401, and is beneficial to improving the stability of the ladder 1 mounted on the mounting seat 401.

[0056] It should be noted that, still referring to Figure 9 and Figure 10 as shown in the figures, preferably, in this embodiment, two mounting posts 4013 may be arranged at intervals inside the housing 4011, each mounting post 4013 is provided with a ladder mounting hole 401a for mounting the ladder 1, and each mounting post 4013 is also arranged inside the housing 4011 through the corresponding reinforcing rib plate 4014. On the basis of being provided with two mounting posts 4013 and making the reinforcing rib plates 4014 have a "meter"-shaped structure, in order to further increase the structural strength of the mounting seat 401, for example, a partition plate located between the two mounting posts 4013 may also be arranged inside the housing 4011, and part of the support plates 40141 in each reinforcing rib plate 4014 may be connected to the partition plate.

[0057] In this embodiment, still in conjunction with Figure 1 , Figure 4 and Figure 10 as shown, in some exemplary embodiments, the mounting seat 401 may, for example, be provided with a blocking plate 4012, which is located at the end of the mounting seat 401 close to the side outer panel 2, and is used to block the end of the housing 4011 close to the side outer panel 2, and the ladder mounting hole 401a for mounting the ladder 1 is arranged to penetrate through the blocking plate 4012.

[0058] In addition, the aforementioned blocking plate 4012 is designed to conform to the shape of the outer side panel 2 and fits together with the inner wall of the outer side panel 2, and a sealant is provided between the blocking plate 4012 and the inner wall of the outer side panel 2.

[0059] Therefore, by providing a blocking plate 4012 at one end of the mounting base 401 near the outer side panel 2, and by fitting the blocking plate 4012 against the inner wall of the outer side panel 2, and by providing sealant between the blocking plate 4012 and the inner wall of the outer side panel 2, this embodiment can obviously utilize the design of the end of the mounting base 401 conforming to the outer side panel 2, so that the mounting base 401 can provide better support for the outer side panel 2, thereby effectively preventing problems such as the collapse of the outer side panel 2 during the installation of the ladder 1, which helps to ensure the appearance quality of the vehicle body.

[0060] Meanwhile, by providing sealant between the blocking plate 4012 and the inner wall of the side outer panel 2, it can be understood that this embodiment can also effectively seal the gap between the mounting base 401 and the side outer panel 2, preventing external water from flowing into the interior of the vehicle side panel through the mounting hole 201 on the side outer panel 2, which is beneficial to improving the sealing of the ladder 1 mounting position.

[0061] In practical implementation, the above-mentioned sealant can be a product commonly used in vehicles that has good adhesion and weather resistance.

[0062] In this embodiment, the mounting bracket 402 is formed by stamping, which is generally a steel sheet metal part. The mounting bracket 402 and the side column 3 can usually be connected by welding to ensure the connection strength between the mounting bracket 402 and the side column 3, thereby ensuring the stability of the entire ladder installation structure on the side column 3.

[0063] Furthermore, in some of the exemplary implementations, combined with Figures 7 to 9 ,as well as Figure 12 As shown, a bracket connection hole 401b may be provided in the mounting base 4012, especially on the mounting post 4013 in the mounting base 401. The mounting base 401 and the mounting bracket 402 can be fixed together by a connector 6. Specifically, the connector 6 passes through a connection through hole 402a on the mounting bracket 402 and is fixed in the bracket connection hole 401b.

[0064] It is understandable that by providing a bracket connection hole 401b in the mounting base 401 and a connection through hole 402a in the mounting bracket 402, and connecting the mounting bracket 402 and the mounting base 401 together through the connector 6 passing through the connection through hole 402a and fixed in the bracket connection hole 401b, it has the advantages of simple structure, easy design, molding and connection operation. At the same time, it obviously facilitates the connection between the mounting base 401 and the mounting bracket 402, and also helps to ensure the reliability of the connection between the mounting bracket 402 and the mounting base 401.

[0065] In specific implementation, it is worth noting that, as a preferred embodiment, the aforementioned connector 6 can be, for example, a bolt, so that the connection between the mounting bracket 402 and the mounting base 401 is achieved by screwing.

[0066] When bolts are used for connector 6, in order to achieve the screw connection of connector 6 in bracket connection hole 401b, a threaded sleeve can generally be embedded in bracket connection hole 401b on the basis of casting mounting base 401, so as to use the screw connection between threaded sleeve and connector 6 to fix mounting bracket 402 and mounting base 401 together.

[0067] In this embodiment, the connecting member 6 can be a bolt. It should be noted that, as a preferred embodiment, the mounting member 5 can also generally be a bolt. In order to realize the screw connection of the mounting member 5 in the ladder mounting hole 401a on the mounting base 401, a threaded sleeve can be embedded in the ladder mounting hole 401a in the specific implementation, so as to use the screw connection between the threaded sleeve and the mounting member 5 to fix the ladder 1 and the mounting base 401 together.

[0068] In this embodiment, since both the ladder mounting hole 401a and the bracket connection hole 401b are provided on the mounting post 4013, in some exemplary embodiments, please refer to Figure 11 As shown, for example, the bracket connection hole 401b on the same mounting column 4013 can be coaxially arranged with the ladder mounting hole 401a, and a partition structure 4015 separating the bracket connection hole 401b and the ladder mounting hole 401a can also be provided in the mounting column 4013.

[0069] This arrangement makes the bracket connection hole 401b and the ladder mounting hole 401a coaxially aligned, and a partition structure 4015 is provided in the mounting column 4013 to separate the coaxially aligned bracket connection hole 401b and ladder mounting hole 401a. It can be understood that, on the one hand, the coaxial alignment of the bracket connection hole 401b and the ladder mounting hole 401a simplifies the structure of the mounting column 4013, that is, the mounting base 401, and facilitates the design and manufacture of the mounting base 401.

[0070] On the other hand, by setting a partition structure 4015 to separate the bracket connection hole 401b and the ladder mounting hole 401a, it is possible to prevent external water from entering the vehicle side panel through the ladder mounting hole 401a and the bracket connection hole 401b, based on the fact that the bracket connection hole 401b and the ladder mounting hole 401a are coaxially arranged, thereby helping to improve the sealing of the ladder mounting position.

[0071] In specific implementation, it is worth noting that, based on the above, the mounting column 4013 in the mounting base 401 can be two, and a ladder mounting hole 401a can be provided on each mounting column 4013. In this case, in order to ensure the reliability of the connection between the mounting base 401 and the mounting bracket 402, a bracket connection hole 401b can also be provided on each mounting column 4013.

[0072] Furthermore, when each mounting post 4013 is provided with both a ladder mounting hole 401a and a bracket connection hole 401b, the ladder mounting hole 401a and the bracket connection hole 401b on each mounting post 4013 are naturally coaxially arranged and separated by a partition structure 4015. The partition structure 4015 is integrally formed within the mounting post 4013 during the casting of the mounting base 401.

[0073] In this embodiment, we continue to combine Figure 12 As shown, in some exemplary embodiments, the mounting bracket 402 may be, for example, U-shaped and has a bracket body 4021 and two arms 4022 connected to the bracket body 4021.

[0074] The aforementioned bracket connection hole 402a is provided on the bracket body 4021, thereby connecting the mounting base 401 to the middle part of the mounting bracket 402, i.e., the bracket body 4021. The two ends of the mounting bracket 402, i.e., the two support arms 4022, are connected to the side wall columns 3, and after being connected to the side wall columns 3, they combine... Figure 3 As shown, a cavity Q is also formed between the mounting bracket 402 and the side column 3.

[0075] It is understandable that by adopting a "U"-shaped structure for the mounting bracket 402, connecting the mounting base 401 to the bracket body 4021 in the middle of the mounting bracket 402, and connecting the two arms 4022 of the mounting bracket 402 to the side column 3, the connection between the mounting base 401 and the mounting bracket 402, as well as between the mounting bracket 402 and the side column 3, can be facilitated. At the same time, the high strength of the "U"-shaped structure can be utilized to further increase the structural strength of the mounting bracket 402 itself, which helps to improve the stability of the mounting base 401 fixed on the side column 3, and also helps to improve the stability of the ladder 1 installed on the vehicle body.

[0076] In practical implementation, based on the "U"-shaped structure of the mounting bracket 402, which includes a bracket body 4021 and a support arm 4022, to further increase the structural strength of the mounting bracket 402, for example, it can still be as follows: Figure 8 and Figure 12 As shown, reinforcing ribs are provided at the positions between the main body 4021 and each support arm 4022, and on each support arm 4022, so as to improve the structural strength of the mounting bracket 402 by using the reinforcing ribs.

[0077] Still Figures 1 to 5 ,as well as Figure 7 and Figure 8 As shown, in some exemplary embodiments, the ladder mounting structure of this embodiment may further include, for example, a mounting support 403 disposed on the outside of the side panel 2.

[0078] The mounting bracket 403 is arranged corresponding to the mounting base 401, and the mounting member 5 passes through the through hole 403a on the mounting bracket 403, while the installed ladder 1 is supported on the mounting bracket 403.

[0079] Thus, by providing a mounting bracket 403 corresponding to the mounting seat 401 on the outer side of the side panel 2, the mounting component 5 passes through the through hole 403a on the mounting bracket 403, and the installed ladder 1 is supported on the mounting bracket 403. It can be understood that, under the support of the mounting seat 401 on the inner side of the side panel 2, and with the support of the mounting bracket 403 on the outer side of the side panel 2, a certain distance is maintained between the installed ladder 1 and the vehicle side panel. This not only facilitates the use of the ladder 1 and improves its practicality, but also helps to avoid bumping the vehicle side panel when using the ladder 1, thus preventing damage to the vehicle's appearance, and also improves the quality of use of the ladder 1.

[0080] In specific implementation, it is worth noting that we should continue to combine... Figure 13 and Figure 14 As shown, the mounting bracket 403 can also be a cast aluminum alloy or magnesium alloy structure, or in addition to being a metal part, it is also possible to make the mounting bracket 403 an injection molded plastic part. However, it should be noted that when using injection molded parts, the mounting bracket 403 should be made of plastic with good structural performance and weather resistance.

[0081] Meanwhile, regardless of whether cast metal parts or injection-molded plastic parts are used, the mounting bracket 403 in this embodiment can also be, for example, as shown in the example... Figure 13 The structure shown is hollow, and through holes 403a can be provided on the mounting support 403, for example, similar to the mounting post 4013 and reinforcing rib plate 4014 in the mounting base 401 described above.

[0082] In this embodiment, based on the arrangement of the above-mentioned mounting support 403, in some exemplary implementation forms, for example, one end of the mounting support 403 close to the side outer panel 2 can be attached to the outer wall of the side outer panel 2, and a sealing gasket 404 is arranged between the mounting support 403 and the side outer panel 2.

[0083] At this time, by attaching the end of the mounting support 403 close to the side outer panel 2 to the outer wall of the side outer panel 2 and arranging the sealing gasket 404 between the mounting support 403 and the side outer panel 2, it can be understood that this not only allows the end of the mounting support 403 to be designed to follow the profile of the side outer panel 2, avoiding problems such as collapse of the side outer panel 2 caused by the force applied to the mounting support 403 during the installation and use of the ladder 1, but also helps ensure the appearance quality of the vehicle body.

[0084] At the same time, by using the sealing gasket 404 arranged between the mounting support 403 and the side outer panel 2, this embodiment can also prevent external water from entering the interior of the vehicle body side wall through the gap between the mounting support 403 and the side outer panel 2 as well as the mounting through hole 201 on the side outer panel 2, which is beneficial to improving the sealing performance of the mounting position of the ladder 1.

[0085] In specific implementation, the above-mentioned sealing gasket 404 can for example adopt gasket products of model PNG8100 or PNG8302 from Bader Sealing, and in addition to using such gasket products, it is certainly feasible for the sealing gasket 404 to use other gasket products with good sealing performance and weather resistance.

[0086] In this embodiment, based on the above introduction to the upper mounting structure 4a, continuing in combination with Figures 15 to 22 as shown, for the lower mounting structure 4b, compared with the upper mounting structure 4a, the main difference lies in that the shapes and structures of the mounting base 401, the mounting bracket 402, the mounting support 403 and the sealing gasket 404 in the lower mounting structure 4b are slightly different, and at the same time, the number of the connecting members 6 in the lower mounting structure 4b is also different.

[0087] In detail, referring to Figure 17 and Figure 18 as shown, the entire mounting base 401 in the lower mounting structure 4b of this embodiment is of an "L" shape structure, and the number of the mounting posts 4013 in the mounting base 401 can be set to three. The reinforcing rib plates 4014 arranged corresponding to the respective mounting posts 4013 adopt structural forms such as a "meter" shape or a "cross" shape, so as to realize the arrangement of the mounting posts 4013 in the mounting base 401, and at the same time form a plurality of support plates 40141 arranged around the mounting posts 4013.

[0088] Furthermore, within the mounting base 401 of the lower mounting structure 4b, each mounting post 4013 is provided with a bracket connection hole 401b, and only some of the mounting posts 4013, such as two of them, are provided with ladder mounting holes 401a for mounting the ladder 1. In this way, on the one hand, by providing bracket connection holes 401b on each mounting post 4013, the number of connecting parts 6 between the mounting bracket 402 and the mounting base 401 can be increased, adapting to the "L"-shaped structural design of the mounting base 401 and ensuring the stability of the mounting base 401 fixed on the side column 3. On the other hand, by providing ladder mounting holes 401a on only two of the mounting posts 4013 for installing the ladder 1, the number of mounting parts 5 can be reduced while meeting the installation requirements of the ladder 1, thus helping to reduce the overall cost of the assembly.

[0089] It should be noted that, given that only some of the mounting columns 4013 in the mounting base 401 of the lower mounting structure 4b have ladder mounting holes 401a, and considering that in this embodiment, the bracket connection holes 401b and ladder mounting holes 401a on the same mounting column 4013 can be coaxially arranged, for mounting columns 4013 that simultaneously have bracket connection holes 401b and ladder mounting holes 401a, the bracket connection holes 401b and ladder mounting holes 401a should be coaxially arranged and separated by the partition structure 4015. For mounting columns 4013 that only need to have bracket connection holes 401b, generally, it is acceptable to form bracket connection holes 401b only on the mounting column 4013, or to reserve ladder mounting holes 401a on the mounting column 4013 in addition to bracket connection holes 401b.

[0090] Whether only the bracket connection hole 401b is provided, or both the bracket connection hole 401b and the ladder mounting hole 401a are provided, a partition structure 4015 must be provided within the mounting base 401, that is, within the mounting column 4013, to ensure a sealing effect at the installation and connection points on the mounting base 401. The partition structure 4015 can be integrally formed within the mounting column 4013 during the casting of the mounting base 401.

[0091] See also Figure 20 As shown in this embodiment, the mounting bracket 402 in the lower mounting structure 4b has a bracket body 4021 and three support arms 4022 connected to the bracket body 4021, which makes it compatible with the "L"-shaped mounting base 401 and different from the "U"-shaped mounting bracket 402 in the upper mounting structure 4a.

[0092] Since the mounting bracket 402 in the lower mounting structure 4b has three support arms 4022, in this embodiment, the mounting base 401 in the lower mounting structure 4b is also connected to the bracket body 4021 and one of the support arms 4022 respectively through multiple connectors 6. Thus, the mounting base 401 is connected to the bracket body 4021 and one support arm 4022 respectively. This ensures the reliability of the connection between the mounting bracket 402 and the mounting base 401, and helps to improve the stability of the mounting base 401 fixed on the side column 3.

[0093] In practical implementation, it is worth noting that, to facilitate the connection between the mounting base 401 and the support arm 4022, such as Figure 10 As shown, for example, during the preparation of the mounting bracket 402, a boss structure can be formed on the support arm 4022 with a connecting through hole 402a. The connecting through hole 402a is located on the boss structure, so that the plane formed by the boss structure can be used to achieve a stable abutment between the mounting base 401 and the support arm 4022.

[0094] Besides connecting one of the support arms 4022 to the mounting base 401 via the connector 6, in other embodiments, more support arms 4022 can be connected to the mounting base 401 according to specific design needs, and there is no limitation on this. However, it is still recommended that the mounting base 401 be mainly connected to the bracket body 4021 in the mounting bracket 402, minimizing the number of support arms 4022 involved in the connection, so as to reduce the design and manufacturing difficulty of the mounting bracket 402.

[0095] Continue as Figure 21 and Figure 22 As shown, the mounting support 403 in the lower mounting structure 4b is basically the same in structure as the mounting support 403 in the upper mounting structure 4a, except that it is larger in size than the mounting support 403 in the upper mounting structure 4a. Correspondingly, the sealing gasket 404 in the lower mounting structure 4b is also larger in size than the sealing gasket 404 in the upper mounting structure 4a.

[0096] In this embodiment, it remains the same. Figure 5 and Figure 6 As shown, in some exemplary embodiments, the ladder 1 may structurally include, for example, vertical bars 101 disposed on both sides, and multiple horizontal bars 102 connected between the two vertical bars 101. The diameter of the horizontal bars 102 is smaller than that of the vertical bars 101, and the ends of the horizontal bars 102 are embedded in the vertical bars 101.

[0097] At this point, the ladder 1 includes vertical bars 101 on both sides and multiple horizontal bars 102 connected between the vertical bars 101 on both sides. The diameter of the horizontal bars 102 is smaller than that of the vertical bars 101, and the ends of the horizontal bars 102 are embedded in the vertical bars 101. It is understood that this facilitates the design and manufacture of the ladder 1, and also helps to ensure the connection strength between the horizontal bars 102 and the vertical bars 101, ensure the stability of the overall structure of the ladder 1, and improve the appearance quality of the ladder 1.

[0098] In practical implementation, it is worth noting that both the vertical bar 101 and the horizontal bar 102 can be made of hollow steel bars. Furthermore, since the end of the horizontal bar 102 is embedded in the vertical bar 101, the horizontal bar 102 and the vertical bar 101 can also be connected by full welding around the perimeter to ensure the reliability of their connection.

[0099] In addition to the vertical bars 101 and horizontal bars 102, to facilitate the installation of the ladder 1, this embodiment may further include mounting plates 103 between the top and bottom of the two vertical bars 101. The mounting components 5 located at the top and bottom of the ladder 1 pass through the mounting plates 103, and the ladder 1 is installed on the vehicle body through the mounting plates 103.

[0100] It is worth noting that, regarding the vehicle-mounted ladder assembly of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 22 As shown, for example, the ladder 1 can be installed at the rear of the vehicle body by means of the mounting member 5, and structurally, it includes the ladder 1 and the mounting structure 4 that cooperates with the mounting member 5 to install the ladder 1 on the vehicle body, and an upper mounting structure 4a and a lower mounting structure 4b are provided corresponding to the top and bottom of the ladder 1, respectively.

[0101] Each mounting structure 4 includes a mounting seat 401 and a mounting bracket 402 disposed between the side pillar 3 and the side outer panel 2 in the vehicle body, and also includes a mounting support 403 disposed on the outside of the side outer panel 2 corresponding to the mounting seat 401.

[0102] The mounting base 401 is cast and fixed to the side column 3 by the mounting bracket 402. The mounting column 4013 is provided with a ladder mounting hole 401a and a bracket connection hole 401b. The mounting piece 5 passes through the mounting through hole 201 on the side outer plate 2 and is fixed in the ladder mounting hole 401a. The mounting bracket 402 is also fixed to the mounting base 401 by the connector 6 passing through the connection through hole 402a on itself and fixed in the bracket connection hole 401b.

[0103] Furthermore, the mounting column 4013 has multiple ladder mounting holes 401a and bracket connection holes 401b. In the upper mounting structure 4a, the bracket connection holes 401b and ladder mounting holes 401a are coaxially arranged. In the lower mounting structure 4b, some bracket connection holes 401b and ladder mounting holes 401a are coaxially arranged. The mounting base 401 has a partition structure 4015 that separates the coaxially arranged bracket connection holes 401b and ladder mounting holes 401a. Meanwhile, the mounting bracket 402 has a bracket body 4021 and multiple support arms 4022. Each support arm 4022 in the mounting bracket 402 is connected to the side column 3, and a cavity Q is formed between the mounting bracket 402 and the side column 3.

[0104] Additionally, the mounting base 401 has a blocking plate 4012 at one end near the outer side panel 2. The blocking plate 4012 is fitted against the inner wall of the outer side panel 2, and sealant is provided between the blocking plate 4012 and the inner wall of the outer side panel 2. Meanwhile, the mounting component 5 passes through the through hole 403a on the mounting support 403, allowing the installed ladder 1 to be supported on the mounting support 403. The end of the mounting support 403 near the outer side panel 2 is also fitted against the outer wall of the outer side panel 2, and a sealing gasket 404 is provided between the mounting support 403 and the outer side panel 2.

[0105] In the preferred embodiment of the above-mentioned vehicle-mounted ladder assembly, the specific configuration and arrangement of the ladder 1, as well as the mounting base 401, mounting bracket 402, mounting support 403, and sealing gasket 404 in the mounting structure 4, can still refer to the descriptions in the above-mentioned exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the ladder 1, mounting base 401, mounting bracket 402, mounting support 403, and sealing gasket 404 can also refer to the descriptions in the above-mentioned exemplary embodiments.

[0106] The vehicle-mounted ladder assembly of this embodiment adopts the above design, which enables the ladder 1 to be installed on the vehicle body, especially at the rear of the vehicle body. Furthermore, the installation strength of the ladder 1 on the vehicle body is improved by setting the cast mounting base 401 and the stamped mounting bracket 402, and by fixing the mounting base 401 to the side pillar 3. This also improves the reliability of the ladder 1 in use, and thus helps to improve the installation and use quality of the ladder 1 on the vehicle.

[0107] An embodiment of the second aspect of this application provides a vehicle in which an on-board ladder assembly as described in the first aspect embodiment above is provided.

[0108] In this embodiment, as mentioned in the first aspect of the embodiment above, the ladder 1 is preferably installed at the rear of the vehicle body via the mounting structure 4 to form a roof-climbing auxiliary structure that can reach the roof directly from the rear of the vehicle.

[0109] In this embodiment, by setting the above-mentioned vehicle-mounted ladder assembly, the ladder 1 can be installed on the vehicle body to assist the user in climbing onto the roof. It can also improve the installation strength of the ladder 1 on the vehicle body and improve the reliability of the ladder 1. It is beneficial to improve the installation quality and usage quality of the ladder 1 on the vehicle, and has good practicality.

[0110] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations.
