[0029] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Reference Figure 1 , Figure 3 as well as Figure 4 As shown, this utility model provides an upper mounting plate connection structure, including a left front side plate 1, a right front side plate 2, a front bulkhead plate 3, a front partition upper mounting plate 4, a first connector 5, and a second connector 6, wherein:

[0031] The mounting plate 4 on the front partition has a first end and a second end. The left front side plate 1 is close to the first end of the mounting plate 4 on the front partition, and the right front side plate 2 is close to the second end of the mounting plate 4 on the front partition. That is, the left front side plate 1 and the right front side plate 2 are located on the left and right sides of the mounting plate 4 on the front partition, respectively, and there is no direct connection between the left front side plate 1 and the right front side plate 2 and the mounting plate 4 on the front partition. The front bulkhead 3 is located to the lower right of the mounting plate 4 on the front partition, close to the right front side plate 2, and there is also no direct connection between it and the right front side plate 2. Therefore, the structural strength of the upper mounting plate connection structure composed of the left front side plate 1, the right front side plate 2, the front bulkhead 3, and the mounting plate 4 on the front partition is poor, and it is prone to deformation or damage when subjected to external forces.

[0032] To improve the structural strength of the upper mounting plate connection structure, the upper mounting plate connection structure of this application is provided with a first connector 5 and a second connector 6. The first connector 5 is connected to the first end of the mounting plate 4 on the front partition and the left front side plate 1, respectively, thereby establishing the connection relationship between the mounting plate 4 on the front partition and the left front side plate 1 through the first connector 5, and increasing the structural strength between the mounting plate 4 on the front partition and the left front side plate 1.

[0033] The second connector 6 is connected to the second end of the mounting plate 4 on the front partition, the right front side plate 2, and the front bulkhead 3 respectively. The mounting plate 4, the right front side plate 2, and the front bulkhead 3 on the front partition are connected by the second connector 6, thereby enhancing the structural strength between the mounting plate 4, the right front side plate 2, and the front bulkhead 3 on the front partition.

[0034] The first connector 5 and the second connector 6 connect the mounting plate 4, the left front side plate 1, the right front side plate 2 and the front bulkhead 3 on the front bulkhead, so that the upper mounting plate connection structure has a continuous triangular area. When the vehicle is involved in a collision, the force of the collision can be effectively dispersed to the upper body area during the collision process, thereby effectively avoiding damage to the upper mounting plate connection structure and enhancing the structural strength of the upper mounting plate connection structure.

[0035] Reference Figure 2 As shown in the embodiment provided in this application, the upper mounting plate connection structure further includes an upper curved beam 7. The upper curved beam 7 has a left extension 71 and a right extension 72 at its opposite ends. The left extension 71 is connected to the left front side plate 1, and the right extension 72 is connected to the right front side plate 2, thereby realizing the connection between the two ends of the upper curved beam 7 and the left front side plate 1 and the right front side plate 2, forming a first loop H1, which further enhances the continuity of the front bulkhead area structure.

[0036] Furthermore, the upper mounting plate connection structure also includes a left front wheel arch 8, a left front beam 9, a right front wheel arch 10, a right front beam 11, and a crossbeam 12. The left extension 71 is connected to one end of the left front wheel arch 8, and the other end of the left front wheel arch 8 is connected to the left front beam 9. The right extension 72 is connected to one end of the right front wheel arch 10, and the other end of the right front wheel arch 10 is connected to the right front beam 11. The left front beam 9 and the right front beam 11 are connected to the opposite ends of the crossbeam 12. Thus, the upper mounting plate 4, left front side plate 1, left extension 71, left front wheel arch 8, left front beam 9, crossbeam 12, right front beam 11, right front wheel arch 10, right extension 72, and right front side plate 2 are sequentially connected to form a structurally continuous and complete second loop H2, which enhances the structural strength of the front bulkhead area.

[0037] Furthermore, the upper mounting plate connection structure also includes a left A-pillar reinforcing plate 13, a right A-pillar reinforcing plate 14, and a top cover beam 15. The first end of the front partition mounting plate 4 is connected to one end of the left A-pillar reinforcing plate 13, and the other end of the left A-pillar reinforcing plate 13 is connected to the top cover beam 15. The second end of the front partition mounting plate 4 is connected to one end of the right A-pillar reinforcing plate 14, and the other end of the right A-pillar reinforcing plate 14 is connected to the top cover beam 15. Thus, the left A-pillar reinforcing plate 13, the front partition mounting plate 4, the right A-pillar reinforcing plate 14, and the top cover beam 15 are sequentially connected to form a third loop H3.

[0038] Reference Figure 2 As shown, when a vehicle is involved in a frontal collision, the impact force borne by the upper curved beam 7 is transmitted to the A-pillar through the left extension 71 and the right extension 72. The second connector 6 distributes the force to the mounting plate 4 on the front bulkhead, adding a lateral connection path and improving collision performance.

[0039] The first ring H1, the second ring H2, and the third ring H3 form three areas of the upper mounting plate connection structure. All three rings are continuous annular structures, which can effectively improve the torsional stiffness and front yaw stiffness of the vehicle.

[0040] In one feasible implementation, refer to Figure 3 As shown, the first connector 5 includes a first bracket 51, which is connected to the first end of the mounting plate 4 on the front partition and the left front side plate 1. Different sides of the first bracket 51 are connected to the first end of the mounting plate 4 on the front partition and the left front side plate 1, respectively, providing support for the mounting plate 4 on the front partition and the left front side plate 1. This not only enables the connection between the mounting plate 4 on the front partition and the left front side plate 1, but also enhances the connection strength between the mounting plate 4 on the front partition and the left front side plate 1.

[0041] Furthermore, the first end of the mounting plate 4 on the front bulkhead is provided with a first mounting point 16, which is used to install the left windshield wiper. The left windshield wiper can be supported by the first bracket 51. Compared with the prior art, the installation position of the left windshield wiper is moved upward, and the left windshield wiper is supported by the first bracket 51, so that the installation of the left windshield wiper is more stable.

[0042] Reference Figure 4 As shown, the second connector 6 includes a second bracket 61, which is connected to the second end of the mounting plate 4 on the front partition, the right front side plate 2, and the front bulkhead 3, respectively. On the one hand, the different sides of the second bracket 61 are connected to the mounting plate 4 on the front partition, the right front side plate 2, and the front bulkhead 3, respectively, thereby connecting the three to form a continuous structure. On the other hand, the second bracket 61 can provide support for the mounting plate 4 on the front partition and the right front side plate, so that the front bulkhead area has better structural strength.

[0043] Reference Figure 3 as well as Figure 4 As shown, a second mounting point 17 is provided on both the left front side panel 1 and the right front side panel 2. The second mounting point 17 is used to install the engine hood. Since the upper mounting plate connection structure has formed a continuous whole, the second mounting point 17 is provided on the left front side panel 1 and the right front side panel 2 respectively to install the engine hood, thereby using the engine hood to further enhance the structural strength of the left and right sides of the upper mounting plate connection structure.

[0044] The upper mounting plate connection structure of this application can also install the right windshield wiper. Therefore, a third bracket 18 is provided on the front bulkhead 3. The third bracket 18 is used to install the right windshield wiper and provides support for the installation of the right windshield wiper, so that the right windshield wiper can be stably fixed on the front bulkhead 3.

[0045] The left and right windshield wipers require power from the wiper motor to operate smoothly. Therefore, a fourth bracket 19 is provided between the front bulkhead 3 and the mounting plate 4 on the front partition. The fourth bracket 19 is connected to both the front bulkhead 3 and the mounting plate 4 on the front partition. The fourth bracket 19 is used to install the wiper motor and provides support for it, so that the wiper motor can be stably fixed between the front bulkhead 3 and the mounting plate 4 on the front partition. This allows the wiper motor to provide stable power to the left and right windshield wipers, supporting their operation.

[0046] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
