[0036] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0037] A combined 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 combined floor support assembly disclosed in the present invention can select different support combinations as needed to adapt to different working conditions, thereby improving the scope of application of the floor assembly.

[0038] Therefore, in actual use, it can meet the differentiated assembly requirements of vehicles with different configurations.

[0039] The combined floor bracket assembly disclosed by the invention is mainly suitable for the rear floor of a vehicle body.

[0040] The combined floor bracket assembly disclosed in the present invention is installed on the rear floor of a vehicle body, and different modules on the rear floor can be installed and connected during subsequent use.

[0041] In the present invention, the combined floor bracket assembly mainly includes a first bracket 1 and / or a second bracket 2; in subsequent use, the first bracket 1 and the second bracket 2 can be used separately or in combination; based on the above design, it can be known that the combined floor bracket assembly disclosed in the present invention can be selected according to different design options according to different usage conditions.

[0042] Specifically, the first bracket 1 is used alone or the second bracket 2 is used alone, or the first bracket 1 and the second bracket 2 are used in combination; based on such a setting, three bracket installation methods can be achieved on a 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 the present invention, the first bracket 1 is mostly used to install a subwoofer speaker; the second bracket 2 is mostly used to install an EVCC (electric vehicle communication controller); the above two modules are only general assembly options, and other module structures can be selected as needed in subsequent use.

[0044] Furthermore, in the present invention, the first bracket 1 includes a first substrate 11, and a first flange 12 is provided at the edge of the first substrate 11; a plurality of first mounting holes 14 are provided on the first substrate 11; the second bracket 2 includes a second substrate 21, and a second flange 22 is provided at the edge of the second substrate 21; a plurality of second mounting holes are provided on the second substrate 21; the first substrate 11 of the present invention is the main plate structure of the first bracket 1, and is also the basic structure for subsequent connection of other modules, and the first flange 12 acts as a connecting plate, and first flanges 12 are provided on opposite sides of the first substrate 11, that is, the first bracket 1 includes at least one The first substrate 11 has a first flange 12 on two opposite sides of the first substrate 11. Based on the above design, the vertical section of the first bracket 1 of the present invention is an "J"-shaped structure. In addition, the first flange 12 of the present invention also serves as a support heightening member, which is convenient for supporting and heightening the corresponding module. At the same time, the first bracket 1 also serves as a reinforcement member, which can well ensure the structural strength of the floor assembly. Similarly, in the present invention, a second flange 22 is also provided on two opposite sides of the second substrate 21, and the second bracket 2 is also equivalent to an "J"-shaped structure, which is convenient for the subsequent installation of the second bracket 2 on the floor body 3; it also facilitates the installation and fixation of the corresponding module.

[0045] In addition, in the present invention, the second substrate 21 is a stepped plate; the stepped second substrate 21 of the present invention has its own limiting capability, which can cooperate with the stepped structure on the corresponding module to achieve installation limiting between the module and the second substrate 21, thereby ensuring the accuracy of the installation position of the corresponding module.

[0046] Furthermore, in the present invention, the first substrate 11 includes a first plate body 111 and a second plate body 112, and the first plate body 111 is connected to the second plate body 112 through a transition plate 113; the first plate body 111 and the second plate body 112 are staggered; a step is formed at the connection between the first plate body 111 and the second plate body 112; based on the above design, the present invention also has the function of making the second substrate 21 form a step plate, which functions similarly to the first substrate 11. In addition, the first plate body 111 of the present invention is the main plate structure of the first substrate 11, and the second plate body 112 acts as a connecting plate or a lap plate, which is convenient for lap limiting with the second substrate 21 during subsequent use.

[0047] In the present invention, the transition plate 113 is required to be arranged perpendicular to the first plate body 111 and the second plate body 112. In subsequent use, in addition to the basic connection function, the transition plate 113 of the present invention can also play a good positioning role. The end of the second substrate 21 of the present invention can be pressed against the transition plate 113 to achieve the position limitation when the second substrate 21 and the first substrate 11 are overlapped.

[0048] Furthermore, in the present invention, an assembly-reducing countersunk hole 13 is provided on the first substrate 11; in the present invention, the assembly-reducing countersunk hole 13 has one function of reducing the weight of the first bracket 1, and another function of facilitating the subsequent positioning of the second substrate 21 during installation; it acts as a positioning hole.

[0049] In addition, in the present invention, a plurality of assembly-reducing countersunk holes 13 can be provided on the first substrate 11, and can be specifically designed as needed. In the present invention, at least one assembly-reducing countersunk hole 13 is located on both the first plate body 111 and the second plate body 112. The assembly-reducing countersunk hole 13 can serve as a positioning hole in subsequent use, and can be used in conjunction with a positioning mechanism to ensure the accuracy of the position of the first bracket 1 and the second bracket 2 when used together.

[0050] Furthermore, in the present invention, the second substrate 21 includes a main body plate, and an avoidance gap 23 is provided on the main body plate; the avoidance gap 23 is U-shaped in horizontal projection; the main body plate is the main structure of the second substrate 21, and the setting of the avoidance gap 23 mainly plays an avoidance role, so that after the subsequent overlap of the first bracket 1 and the second bracket 2, the second bracket 2 will not cover the assembly reduction countersunk hole 13 on the first substrate 11; in other words, the avoidance gap 23 is similar to a part of the end of the assembly reduction countersunk hole 13.

[0051] In the present invention, the second substrate 21 is overlapped on the second plate body 112; at least one inner wall side surface of the avoidance gap 23 is on the same plane as the inner side surface of the assembly reduction countersunk hole 13 on the first substrate 11; such a setting facilitates the subsequent coordination 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 the present invention, a positioning mechanism 4 is provided between the first substrate 11 and the second substrate 21 , and the positioning mechanism 4 is mainly used to define the relative position of the first bracket 1 and the second bracket 2 , so as to facilitate mutual calibration between the two brackets.

[0053] In the present invention, a plurality of positioning mechanisms 4 may be disposed between the first substrate 11 and the second substrate 21 , and generally, two positioning mechanisms 4 are sufficient.

[0054] The positioning mechanism 4 described in the present invention includes a hanging plate 41 arranged on the inner wall of the avoidance notch 23, and the hanging plate 41 passes through the assembly reduction countersunk hole 13 and is connected to the first substrate 11; the hanging plate 41 is provided with 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 is hung on the first substrate 11, thereby achieving the stability of the connection position between the first substrate 11 and the second substrate 21; subsequently, in conjunction with the transition plate 113, the end of the second substrate 21 abuts against the transition plate 113, based on such a 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 the present invention, a support cushion layer 43 is disposed on the inner side surface of the first substrate 11; in the present invention, the support cushion layer 43 can be a rubber layer.

[0056] In the present invention, the support cushion layer can be used in conjunction with the positioning mechanism. The support cushion layer plays a good supporting role and can achieve the stability of the positioning mechanism hanging on the first bracket, thereby ensuring the stability of the position of the overlap between the first bracket and the second bracket.

[0057] At the same time, the transition plate of the present invention is distributed along the longitudinal direction, and the transition plate is pressed 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 combined floor bracket assembly is arranged; the floor body 3 includes a floor base, on which a plurality of reinforcing ribs 31 are arranged; in the present invention, the structural strength of the floor body 3 can be ensured by the arrangement of the reinforcing ribs 31. In addition, the present invention can select different bracket combinations as needed to adapt to different working conditions through the arrangement of the combined floor bracket assembly, thereby improving the application range of the floor assembly.

[0059] Therefore, in actual use, it can meet the differentiated assembly requirements of vehicles with different configurations.

[0060] At the same time, in the present invention, at least two reinforcing ribs 31 are arranged in parallel at intervals on the floor substrate; the above-mentioned two reinforcing ribs 31 are arranged in parallel at intervals to form an assembly gap. When used subsequently, the first flange 12 on the first bracket 1 can be snapped into the assembly gap, thereby realizing the installation limit between the floor body 3 and the first bracket 1. It should be noted here that the vertical cross-sections of the first flange 12 and the second flange 22 disclosed in the present invention are both L-shaped. Specifically, in the present invention, the first flange 12 includes a first longitudinal flange 121 and a first transverse flange 122, and the first transverse flange 122 is arranged parallel to the first base plate 11; when used subsequently, the first transverse flange 122 is snapped into the above-mentioned assembly gap, thereby realizing the installation positioning of the first bracket 1 on the floor body 3.

[0061] Furthermore, when the first bracket 1 and the second bracket 2 in the combined floor bracket assembly described in the present invention are simultaneously connected to the floor body 3, it is required that the first bracket 1 is first installed on the floor body 3, and then the second bracket 2 is overlapped on the first bracket 1, and then the second bracket 2 and the floor body 3 are fixedly connected; based on such a connection limitation, the first bracket 1 can be used for installation positioning of the second bracket 2 before installation, thereby ensuring the accuracy of the installation position of the second bracket 2 and reducing the use of external fixing accessories.

[0062] Furthermore, when the first bracket 1 and the second bracket 2 in the combined floor bracket assembly described in the present invention are simultaneously connected to the floor body 3, the first bracket 1 and the second bracket 2 are arranged in the same direction; such a setting can facilitate the mutual limitation of the first bracket 1 and the second bracket 2 during subsequent use, and when the first bracket 1 and the second bracket 2 are used in combination, the interference problem during the installation of the first bracket 1 and the second bracket 2 can be avoided.

[0063] specific:

[0064] The present invention discloses a combined floor bracket assembly, which includes a first bracket 1 and / or a second bracket 2; the first bracket 1 and the second bracket 2 can be used separately or in combination.

[0065] Based on the above, the first bracket 1 and the second bracket 2 disclosed in the present invention can be used alone or in combination.

[0066] The first bracket 1 and the second bracket 2 can be connected to the vehicle body by spot welding, CO2 welding, riveting, bolts, bonding, SPR or other solutions, or they can be connected to each other as a combination and then connected to the vehicle body as a whole.

[0067] The material can be metal plate or polymer material, and the material thickness can be selected in different specifications according to the strength requirements. Multiple fixing points for assembling functional modules are designed on the first bracket 1 and the second bracket 2. These fixing points should try to take into account the use requirements of multiple modules at the same time, and various grooves, steps, reinforcing ribs 31, etc. are designed on the bracket body for reinforcement.

[0068] Holes can be designed in non-functional areas to reduce weight.

[0069] In addition to the above combination, the present invention can also use three or four equal brackets to increase the use range of the floor assembly.

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

[0071] The first bracket and the second bracket can be connected to the floor body separately, or installed on the floor body in sequence, or combined and connected to the rear floor body 3 as a whole.

[0072] According to the CAE analysis conclusion, the number of connections between the connected bracket combination 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 alone, so as to improve production efficiency and reduce production costs.

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

[0074] The material is a metal plate or a polymer material, and the thickness of the material can be selected in different specifications according to the strength requirements. A connection structure and reinforcing ribs 31 are designed on the rear floor body 3.

[0075] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods.
