[0073] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0074] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0075] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0076] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0077] In the drawings herein, the first direction X represents the longitudinal direction of the reinforcement (also representing the direction from the front of the vehicle to the rear of the vehicle), the second direction Y represents the lateral direction of the reinforcement, and the third direction Z represents the height direction of the reinforcement (also representing the direction from the bottom of the vehicle to the roof). The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0078] In a first aspect, an embodiment of the present application provides a vehicle reinforcement member for installation on a vehicle. Figure 1a Below the central tunnel 71 of the front floor 7 of the vehicle shown. Figure 1 As shown, the reinforcement member 1 includes a first mounting portion 1a, a second mounting portion 1b, a third mounting portion 1c, and a fourth mounting portion 1d. The two first mounting portions 1a are arranged opposite each other in the transverse direction (second direction Y), the second mounting portion 1b is located between the two first mounting portions 1a, and the first mounting portion 1a, the third mounting portion 1c, and the fourth mounting portion 1d are spaced apart in the longitudinal direction (first direction X). In other words, the second mounting portion 1b, the third mounting portion 1c, and the fourth mounting portion 1d are spaced apart in the longitudinal direction (first direction X).

[0079] Each first mounting part 1a is used to install the corresponding transmission mounting bracket, the second mounting part 1b is used to install the motor suspension mounting bracket, the third mounting part 1c is used to install the shift assembly, and the fourth mounting part 1d is used to install the drive shaft mounting bracket assembly or the handbrake mounting reinforcement plate. The corresponding installation methods of each mounting part include welding and / or bolted connection.

[0080] The reinforcement member 1 of the embodiment of the present application can be combined with at least one of the transmission mounting bracket, the motor suspension mounting bracket, the shift assembly, the drive shaft mounting bracket assembly and the handbrake mounting reinforcement plate. The formed assembly can be applied to vehicles of different power types. The following content of this article introduces three embodiments of the assembly including the reinforcement member 1.

[0081] For example, the first mounting portion 1a of the reinforcement member 1 may be connected to Figure 2-Figure 4 The third mounting portion 1c of the reinforcement member 1 can be connected to the shift assembly (not shown in the figure), and the fourth mounting portion 1d of the reinforcement member 1 can be connected to the transmission mounting bracket 2 shown in the figure. Figure 2-Figure 4 The drive shaft mounting bracket assembly 4 is shown as being connected. Under this setting, the reinforcement 1 can be applied to pure fuel-powered vehicles (using oil fuel, hydrogen fuel or ethanol fuel as the vehicle power source).

[0082] For example, the first mounting portion 1a of the reinforcement member 1 may be connected to Figure 5-Figure 7 The transmission mounting bracket 2 is connected to the second mounting portion 1b of the reinforcement 1, and the second mounting portion 1b of the reinforcement 1 can be connected to the transmission mounting bracket 2 as shown. Figure 6-Figure 7 The motor suspension mounting bracket 3 is connected, and the fourth mounting portion 1d of the reinforcement member 1 is connected to the motor suspension mounting bracket 3 shown in FIG. Figure 5-Figure 7 The handbrake is mounted with a reinforcement plate 5 as shown. In this arrangement, the reinforcement 1 can be applied to hybrid vehicles (using electricity and fuel as vehicle power sources).

[0083] For example, the fourth mounting portion 1d of the reinforcement member 1 may be connected to Figures 8-10 The handbrake is installed in connection with the reinforcement plate 5. Under this setting, the reinforcement 1 can be applied to pure electric vehicles (using electricity as the vehicle power source).

[0084] The existing reinforcements installed below the center tunnel of the front floor differ in structure for vehicles of different powertrain types. This requires manufacturers to utilize specialized production processes, equipment, and production lines, among other specialized resources, to produce these reinforcements. To meet market demand for vehicles with diverse powertrain types, manufacturers may need a variety of processes, equipment, and production lines to produce reinforcements suitable for these diverse types of vehicles. This results in complex production processes, increased production difficulty, and longer production cycles. Given the fluctuating market demand for vehicles, if demand for one powertrain type is low, demand for reinforcements suitable for that type will also be low, resulting in reduced availability of the production equipment and production lines needed to produce these reinforcements. However, if demand for another powertrain type increases, demand for reinforcements suitable for that type will also increase, potentially leading to insufficient production equipment and production lines, resulting in reduced production efficiency.

[0085] Therefore, compared with the reinforcements in the prior art, the reinforcement 1 provided in the embodiment has a higher degree of universality and can be applied to pure electric vehicles, pure fuel-powered vehicles and hybrid vehicles. For manufacturers, the number of process flows, production equipment and production lines required to prepare the reinforcement 1 is relatively small. Accordingly, the production process will be relatively simple, the production difficulty will be relatively low, the production cycle will be relatively short, and the availability of the production equipment and production lines owned by the manufacturer will be higher and the production efficiency will be higher.

[0086] Alternatively, see Figure 11 As shown, the reinforcement 1 includes a middle structural panel 11, a first side structural panel 12, and a second side structural panel 13. The middle structural panel 11, the first side structural panel 12, and the second side structural panel 13 are integrally formed. The first side structural panel 12 and the second side structural panel 13 are both inclined relative to the middle structural panel 11. The first side structural panel 12 and the second side structural panel 13 are arranged opposite each other in the transverse direction (second direction Y), with the middle structural panel 11 located between the first side structural panel 12 and the second side structural panel 13. With this arrangement, the reinforcement 1 has an arched structure, which enhances the bending strength of the reinforcement 1 and, in turn, increases the bending strength of the central tunnel 71 of the front floor 7.

[0087] The first side structural panel 12 includes one first mounting portion 1a, the second side structural panel 13 includes another first mounting portion 1a, and the intermediate structural panel 11 includes a second mounting portion 1b. In this arrangement, the two first mounting portions 1a are disposed opposite each other in the transverse direction (second direction Y), with the second mounting portion 1b located between the two first mounting portions 1a. The intermediate structural panel 11 also includes a third mounting portion 1c and a fourth mounting portion 1d. The second mounting portion 1b, third mounting portion 1c, and fourth mounting portion 1d are spaced apart in the longitudinal direction (first direction X) on the intermediate structural panel 11.

[0088] In addition, the reinforcement member 1 is stamped from the same plate material.

[0089] Alternatively, see Figure 11 As shown, the first side structural plate 12 includes a first bent portion 121 and a first flat portion 122 connected to each other. The first flat portion 122 is connected to the middle structural plate 11 via the first bent portion 121. In this configuration, the first side structural plate 12 has an arched structure, which can enhance the bending strength of the first side structural plate 12.

[0090] The protruding direction (stamping deformation direction) of the first bent portion 121 can be decomposed into a direction opposite to the direction Z and a direction opposite to the second direction Y. The first bent portion 121 encloses a first groove 121 a , the opening of which faces the central channel 71 of the front floor 7 .

[0091] Alternatively, see Figure 11 As shown, the second side structural plate 13 includes a second bent portion 131 and a second flat portion 132 connected to each other, and the second flat portion 132 is connected to the middle structural plate 11 via the second bent portion 131. In this arrangement, the second side structural plate 13 has an arched structure, which can enhance the bending strength of the second side structural plate 13.

[0092] The protruding direction (stamping deformation direction) of the second bent portion 131 can be decomposed into a second direction Y and a reverse direction Z. The second bent portion 131 encloses a second groove 131 a , the opening of which faces the central channel 71 of the front floor 7 .

[0093] Alternatively, see Figure 1 As shown, the reinforcement 1 further includes a fifth mounting portion 1e, which is located between the first mounting portion 1a and the fourth mounting portion 1d. In other words, the first mounting portion 1a, the fifth mounting portion 1e and the fourth mounting portion 1d are spaced apart in the longitudinal direction (the first direction X). The fifth mounting portion 1e is used to mount the Figure 3 、 Figure 6 and Figure 9The crossbeam connector 6 shown is used to connect the crossbeam structure of the vehicle (not shown in the figure) to improve the structural strength of the reinforcement 1.

[0094] In a second aspect, the embodiments of the present application provide three types of front floor assemblies for vehicles, which are respectively applied to vehicles of different power types.

[0095] Please refer to Figure 12 The front floor assembly 10 of the first embodiment shown includes a front floor panel 7, a transmission mounting bracket 2, a drive shaft mounting bracket assembly 4, and the reinforcement 1 described above. There are two transmission mounting brackets 2, and the front floor panel 7 has a central tunnel 71 (in a "F" or U-shaped configuration). The reinforcement 1 is mounted below the central tunnel 71. One transmission mounting bracket 2 is located below the front floor panel 7 and is mounted to one of the first mounting portions 1a of the reinforcement 1. Alternatively, one transmission mounting bracket 2 is mounted to the first side structural plate 12. Another transmission mounting bracket 2 is located below the front floor panel 7 and is mounted to the other first mounting portion 1a of the reinforcement 1. Alternatively, another transmission mounting bracket 2 is mounted to the second side structural plate 13. The drive shaft mounting bracket assembly 4 is located below the front floor panel 7 and is mounted to the fourth mounting portion 1d. With this configuration, the front floor panel 10 can be used in purely fuel-powered vehicles.

[0096] Please refer to Figure 13-14 As shown, the transmission mounting bracket 2 includes a first body 21 and a first nut plate 22. The first body 21 encloses a receiving groove 21a, and the first nut plate 22 is located in the receiving groove 21a. Both the first body 21 and the first nut plate 22 are used to pass through fasteners (bolts) connected to the transmission. The first nut plate 22 can improve the structural strength of the first body 21.

[0097] In addition, please refer to Figure 14 As shown, the first body 21 includes a flange structure 211 and a reinforcement structure 212. One end of the flange structure 211 can be welded to the reinforcement member 1, and the other end of the flange structure 211 can be welded to the central channel 71. In this arrangement, the connection structure between the flange structure 211, the reinforcement member 1, and the central channel 71 is relatively strong. The reinforcement structure 212 is an "X" or "U" structure, so that the reinforcement structure 212 can enclose the receiving groove 21a. Secondly, the reinforcement structure 212 has a high bending strength.

[0098] Furthermore, the first body 21 is formed by stamping the same plate. Compared with the first body of the transmission mounting bracket composed of two welded parts in the prior art, the first body 21 of the embodiment of the present application has higher structural strength; secondly, the weight of the first body 21 of the embodiment of the present application is relatively small, which makes the transmission mounting bracket 2 have the advantage of being lightweight; furthermore, the manufacturing process of the first body 21 of the embodiment of the present application is relatively simple.

[0099] Alternatively, see Figure 3-Figure 4 As shown, the drive shaft mounting bracket assembly 4 includes a drive shaft mounting base plate 41, a drive shaft bracket 42, and two drive shaft mounting reinforcement plates 43. The drive shaft mounting base plate 41 is located below the front floor 7 and connected to the fourth mounting portion 1d. The drive shaft mounting base plate 41 is also connected to the front floor 7. The drive shaft bracket 42 is located below the drive shaft mounting base plate 41. The two drive shaft mounting reinforcement plates 43 are installed below the front floor 7 and are spaced apart and symmetrically arranged in the transverse direction (second direction Y). One of the drive shaft mounting reinforcement plates 43 is connected to one side of the drive shaft mounting base plate 41 and one side of the drive shaft bracket 42, and the other drive shaft mounting reinforcement plate 43 is connected to the other side of the drive shaft mounting base plate 41 and the other side of the drive shaft bracket 42.

[0100] Please refer to Figure 15 As shown, the transmission shaft bracket 42 includes a second body 421 and two second nut plates 422. The second nut plates 422 are used to be installed on the boss 421a of the second body 421. The boss 421a and the second nut plates 422 are both used to be penetrated by fasteners (bolts) connected to the transmission shaft bracket (not shown in the figure). The second nut plates 422 can improve the structural strength of the boss 421a. The second body 421 also includes an arc-shaped recessed portion 421b. The stress concentration of the arc-shaped recessed portion 421b is relatively small, and the arc-shaped recessed portion 421b is not prone to structural problems such as cracking and breaking. The second body 421 also includes a plurality of reinforcing ribs 421c located in the arc-shaped recessed portion 421b. The plurality of reinforcing ribs 421c can improve the structural strength of the arc-shaped recessed portion 421b.

[0101] In addition, please refer to Figure 15 As shown, the transmission shaft bracket 42 of the embodiment of the present application is formed by stamping the same plate material. Compared with the transmission shaft bracket composed of multiple welded parts in the prior art, the transmission shaft bracket 42 of the embodiment of the present application has higher structural strength; secondly, the transmission shaft bracket 42 of the embodiment of the present application is lighter, which makes the transmission shaft bracket 42 have the advantage of being lightweight; furthermore, the manufacturing process of the transmission shaft bracket 42 of the embodiment of the present application is relatively simplified.

[0102] Furthermore, please refer to Figure 3-Figure 4As shown, the two driveshaft mounting reinforcement plates 43 have the same structure and are therefore interchangeable. In other words, their mounting positions are interchangeable. For manufacturers, the production of the driveshaft mounting reinforcement plates 43 and the front floor assembly 10 requires fewer processes, fewer production equipment, and fewer production lines. Consequently, the production process is simplified, production difficulty is reduced, and production cycle times are shortened. This results in higher utilization and production efficiency for the manufacturer's production equipment and production lines. The two driveshaft mounting reinforcement plates 43 are also used to connect to the vehicle's front beam to enhance the structural strength of the front floor assembly 10.

[0103] Please refer to Figure 16 The front floor assembly 10 of the second embodiment shown includes a front floor panel 7, a parking brake mounting reinforcement plate 5, and the reinforcement member 1 described above. The front floor panel 7 has a central channel 71, with the reinforcement member 1 mounted below the central channel 71. The parking brake mounting reinforcement plate 5 is located below the front floor panel 7 and mounted on the fourth mounting portion 1d. With this configuration, the front floor panel 10 can be used in pure electric vehicles. The front floor panel 10 also includes a bottom cross member 8, which is mounted below the front floor panel 7 and below the reinforcement member 1. The bottom cross member 8 serves to increase the structural strength of the front floor panel 7.

[0104] Please refer to Figure 17 The front floor assembly 10 of the third embodiment shown includes a front floor 7, two transmission mounting brackets 2, a motor suspension mounting bracket 3, a handbrake mounting reinforcement plate 5, and the reinforcement 1 described above. One of the transmission mounting brackets 2 is located below the front floor 7 and mounted to one of the first mounting portions 1a of the reinforcement 1. Alternatively, one of the transmission mounting brackets 2 is mounted to the first side structural plate 12. Another transmission mounting bracket 2 is located below the front floor 7 and mounted to the other first mounting portion 1a of the reinforcement 1. Alternatively, another transmission mounting bracket 2 is mounted to the second side structural plate 13. The motor suspension mounting bracket 3 is located below the reinforcement 1 and mounted to the second mounting portion 1b. The handbrake mounting reinforcement plate 5 is located below the front floor 7 and mounted to the fourth mounting portion 1d of the reinforcement 1. With this configuration, the front floor assembly 10 can be used in hybrid vehicles.

[0105] The front floor assembly 10 of the above three embodiments also includes a cross-beam connector 6 . The cross-beam connector 6 is located below the reinforcement 1 and is mounted on the fifth mounting portion 1 e of the reinforcement 1 .

[0106] In a third aspect, an embodiment of the present application provides a vehicle, which includes the front floor assembly 10 of the three embodiments described above.

[0107] If the vehicle includes Figure 12 If the front floor assembly 10 is shown, the vehicle may be a purely fuel-powered vehicle.

[0108] If the vehicle includes Figure 16 If the front floor assembly 10 is shown, the vehicle may be a pure electric vehicle.

[0109] If the vehicle includes Figure 17 If the front floor assembly 10 is shown, the vehicle may be a hybrid vehicle.
