Technical Field

[0001] This invention relates to the field of vehicle bodies, and more specifically to a combined floor support assembly and a floor assembly having the combined floor support assembly. Background Technology

[0002] As car functions increase, more and more functional modules need to be mounted on the car body using brackets. However, due to the differentiated needs of consumers for functions and the differences in the functional definitions of different configuration models by car manufacturers, the mounting location and number of functional modules vary for each model.

[0003] This makes traditional fixed support structures unable to meet diverse assembly needs, and may also increase production costs and assembly difficulty.

[0004] The existing patent 202223316383.2 - Rear floor and middle rear floor assembly of automobiles does not clearly disclose the technical content that solves the above-mentioned technical problems.

The hanging plate passes through the assembly material reduction countersunk hole and is connected to the first substrate. A hanging protrusion is provided at the end of the hanging plate away from the second substrate. A support pad layer is provided on the inner side of the first substrate.

[0036] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0037] A modular floor support assembly includes a first support 1 and / or a second support 2; the first support 1 and the second support 2 can be used separately or in combination; the modular floor support assembly disclosed in this invention can select different support combinations as needed to adapt to different working conditions, thereby improving the applicability of the floor assembly.

[0038] Therefore, in actual use, it can meet the differentiated assembly requirements of different configuration models.

[0039] The modular floor support assembly disclosed in this invention is mainly applicable to the rear floor of a vehicle.

[0040] The modular floor support assembly disclosed in this invention is installed on the rear floor of the vehicle, and different modules on the rear floor can be installed and connected during subsequent use.

[0041] In this invention, the modular floor support assembly mainly includes a first support 1 and / or a second support 2; in subsequent use, the first support 1 and the second support 2 can be used separately or in combination; based on the above design, it can be understood that the modular floor support assembly disclosed in this invention can be designed differently according to different working conditions.

[0042] Specifically, the first bracket 1 can be used alone or the second bracket 2 can be used alone, or the first bracket 1 and the second bracket 2 can be used in combination. Based on this setting, three bracket installation methods can be achieved on a single floor body 3. Based on the above design, the corresponding bracket combination can be selected according to the different configuration requirements of the vehicle model, thereby ensuring the installation and fixation of the corresponding module on the floor body 3.

[0043] In this invention, the first bracket 1 is mainly used to install a subwoofer speaker; the second bracket 2 is mainly used to install an EVCC (electric vehicle communication controller); the above two modules are just general assembly options, and other module structures can be selected as needed in subsequent use.

[0044] Furthermore, in this invention, the first support 1 includes a first substrate 11, with a first flange 12 at its edge; the first substrate 11 has a plurality of first mounting holes 14; the second support 2 includes a second substrate 21, with a second flange 22 at its edge; the second substrate 21 has a plurality of second mounting holes; the first substrate 11 is the main plate structure of the first support 1 and also the basic structure for connecting other modules. The first flange 12 acts as a connecting plate, and is provided on both opposite sides of the first substrate 11, meaning the first support 1 includes at least one... The first substrate 11 has a first flange 12 on each of its opposite sides. Based on the above design, the vertical cross-section of the first support 1 of the present invention is shaped like a "Z". In addition, the first flange 12 of the present invention also serves as a support for raising the height of the corresponding module. At the same time, the first support 1 also serves as a reinforcing member, which can effectively ensure the structural strength of the floor assembly. Similarly, in the present invention, the second substrate 21 also has a second flange 22 on each of its opposite sides. The second support 2 is also equivalent to a "Z" shaped structure, which facilitates the subsequent installation of the second support 2 on the floor body 3. It also facilitates the installation and fixing of the corresponding module.

[0045] In addition, in this invention, the second substrate 21 is a stepped plate; the stepped second substrate 21 of this invention has its own limiting capability, which can be used in conjunction with the stepped structure on the corresponding module to realize the installation limiting between the module and the second substrate 21, and ensure the accuracy of the installation position of the corresponding module.

[0046] Furthermore, in this invention, the first substrate 11 includes a first plate 111 and a second plate 112. The first plate 111 is connected to the second plate 112 via a transition plate 113. The first plate 111 and the second plate 112 are staggered. A stepped platform is formed at the connection between the first plate 111 and the second plate 112. Based on the above design, one function of this invention is to make the second substrate 21 form a stepped plate, similar to the function of the first substrate 11. In addition, the first plate 111 is the main plate structure of the first substrate 11, and the second plate 112 acts as a connecting plate or overlapping plate to facilitate overlapping and limiting with the second substrate 21 during subsequent use.

[0047] In this invention, the transition plate 113 is required to be set perpendicular to the first plate 111 and the second plate 112. In subsequent use, in addition to the basic connection function, the transition plate 113 can also play a good positioning role. The end of the second substrate 21 can press against the transition plate 113 to limit the position when the second substrate 21 overlaps with the first substrate 11.

[0048] Furthermore, in this invention, the first substrate 11 is provided with a countersunk hole 13 for reducing material weight; in this invention, the countersunk hole 13 for reducing material weight weight reduces the weight of the first support 1 and facilitates positioning during subsequent installation of the second substrate 21; it acts as a positioning hole.

[0049] In addition, in this invention, a plurality of assembly material reduction countersunk holes 13 can be provided on the first substrate 11, which can be designed according to needs. In this invention, at least one assembly material reduction countersunk hole 13 is located on both the first plate 111 and the second plate 112. The assembly material reduction countersunk hole 13 can be used as a positioning hole in subsequent use, and can be used in conjunction with the positioning mechanism to ensure the accuracy of the position when the first bracket 1 and the second bracket 2 are used together.

[0050] Furthermore, in this invention, the second substrate 21 includes a main body plate, and the main body plate is provided with an avoidance notch 23; the avoidance notch 23 is U-shaped in horizontal projection; the main body plate is the main structure of the second substrate 21, and the avoidance notch 23 is mainly provided to avoid obstacles, so that after the first support 1 and the second support 2 are connected, the second support 2 will not cover the assembly material reduction countersunk hole 13 on the first substrate 11; in other words, the avoidance notch 23 is similar to a part of the end of the assembly material reduction countersunk hole 13.

[0051] In this invention, the second substrate 21 overlaps the second plate 112; at least one inner wall side of the clearance notch 23 is on the same plane as the inner side of the assembly material reduction countersunk hole 13 on the first substrate 11; such a setting facilitates the subsequent use of the positioning mechanism to achieve the accuracy of the relative installation position of the first bracket 1 and the second bracket 2.

[0052] Furthermore, in this invention, a positioning mechanism 4 is provided between the first substrate 11 and the second substrate 21. The positioning mechanism 4 is mainly used to limit the relative position of the first support 1 and the second support 2, so as to facilitate mutual calibration between the two supports.

[0053] In this invention, multiple positioning mechanisms 4 can be provided between the first substrate 11 and the second substrate 21, generally two positioning mechanisms 4 are sufficient.

[0054] The positioning mechanism 4 of the present invention includes a hanging plate 41 disposed on the inner wall of the clearance notch 23. The hanging plate 41 passes through the assembly material reduction countersunk hole 13 and is connected to the first substrate 11. The hanging plate 41 has a hanging protrusion 42 at the end away from the second substrate 21. The positioning mechanism 4 of the present invention is essentially a hook structure. The hook extends from the second substrate 21, passes through the first substrate 11, and hangs on the first substrate 11, thereby achieving the stability of the connection position between the first substrate 11 and the second substrate 21. Subsequently, with the help of the transition plate 113, the end of the second substrate 21 abuts against the transition plate 113. Based on this setting, the relative position of the first substrate 11 and the second substrate 21 is limited during installation, thereby better ensuring the accuracy of the relative installation position of the first bracket 1 and the second bracket 2.

[0055] Meanwhile, in this invention, a support pad layer 43 is provided on the inner side of the first substrate 11; in this invention, the support pad layer 43 can be a rubber layer.

[0056] In this invention, the support pad can be used in conjunction with the positioning mechanism. The support pad plays a good supporting role, which can ensure the stability of the positioning mechanism when it is attached to the first bracket, thereby ensuring the stability of the position at the joint between the first bracket and the second bracket.

[0057] Meanwhile, the transition plate of the present invention is distributed longitudinally, and the transition plate presses against the end of the second bracket, which plays a good role in lateral installation and positioning.

[0058] A floor assembly includes a floor body 3, on which the aforementioned modular floor support assembly is provided; the floor body 3 includes a floor base, on which a plurality of reinforcing ribs 31 are provided; in this invention, the structural strength of the floor body 3 can be ensured by the setting of the reinforcing ribs 31; in addition, the modular floor support assembly allows for the selection of different support combinations as needed to adapt to different working conditions, thereby improving the applicability of the floor assembly.

[0059] Therefore, in actual use, it can meet the differentiated assembly requirements of different configuration models.

[0060] Meanwhile, in this invention, at least two reinforcing ribs 31 are distributed parallel to each other on the floor substrate. The two reinforcing ribs 31 are distributed to form an assembly gap. In subsequent use, the first flange 12 on the first bracket 1 can be engaged in the assembly gap, thereby realizing the installation positioning between the floor body 3 and the first bracket 1. It should be noted that the vertical cross-section of the first flange 12 and the second flange 22 disclosed in this invention is L-shaped. Specifically, in this invention, the first flange 12 includes a first longitudinal flange 121 and a first transverse flange 122. The first transverse flange 122 is arranged parallel to the first base plate 11. In subsequent use, the first transverse flange 122 is engaged in the assembly gap, thereby realizing the installation positioning of the first bracket 1 on the floor body 3.

[0061] Furthermore, in the combined floor support assembly described in this invention, when the first support 1 and the second support 2 are simultaneously connected to the floor body 3, the first support 1 is required to be installed on the floor body 3 first, and then the second support 2 is attached to the first support 1, and then the second support 2 is fixedly connected to the floor body 3. Based on this connection limitation, the first support 1 can be used for the installation positioning of the second support 2 before installation, ensuring the accuracy of the installation position of the second support 2, and reducing the use of external fixing accessories.

[0062] Furthermore, in the combined floor support assembly described in this invention, when the first support 1 and the second support 2 are simultaneously connected to the floor body 3, the first support 1 and the second support 2 are arranged in the same direction. This arrangement facilitates mutual positioning of the first support 1 and the second support 2 during subsequent use, and avoids interference problems during the installation of the first support 1 and the second support 2 when they are used in combination.

[0063] specific:

[0064] The present invention discloses a modular floor support assembly, comprising a first support 1 and / or a second support 2; the first support 1 and the second support 2 can be used separately or in combination.

[0065] Based on the above, the first support 1 and the second support 2 disclosed in this invention can be used individually or in combination.

[0066] Both the first bracket 1 and the second bracket 2 can be connected to the vehicle body by spot welding, CO2 welding, riveting, bolting, bonding, SPR or other methods. They can also be connected to each other as a whole and then connected to the vehicle body as a whole.

[0067] The material can be metal plate or polymer material, and the thickness can be selected according to the strength requirements. Multiple fixing points for functional module assembly are designed on the first bracket 1 and the second bracket 2. These fixing points should take into account the usage requirements of multiple modules as much as possible. Various grooves, steps, and reinforcing ribs 31 are designed on the bracket body for reinforcement.

[0068] Non-functional areas can be designed with holes and openings to reduce weight.

[0069] In addition to the above-mentioned combination, the present invention can also increase the application range of the floor assembly by combining three or four equal supports.

[0070] The first support 1 and the second support 2 can be connected by spot welding, CO2 welding, riveting, bolting, bonding, SPR or other methods.

[0071] The first and second brackets can be connected to the floor body individually, or they can be installed sequentially on the floor body, or they can be combined as a whole and connected to the rear floor body 3.

[0072] Based on the CAE analysis results, the number of connections between the connected bracket assembly and the rear floor body 3 is optimized to be less than the sum of the number of connections between each bracket and the floor body 3 when used individually, so as to improve production efficiency and reduce production costs.

[0073] The rear floor disclosed in this invention can be connected to a single bracket or to a combined bracket assembly.

[0074] The material can be metal plate or polymer material, and the thickness can be selected according to the strength requirements. The connecting structure and reinforcing ribs 31 are designed on the rear floor body 3.

[0075] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
