[0001] The utility model relates to the technical field of vehicles, and in particular, to a wiper bracket mounting structure, a front engine compartment assembly and a vehicle. Background Art

[0002] The wiper is usually installed at the front engine compartment position. The transmission structure of the wiper drives the wiper to rotate forward and backward to remove the water on the windshield surface.

[0029] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0030] The following refers to the attached Figures 1 to 4 Describe the wiper bracket mounting structure, front engine compartment assembly and vehicle according to the embodiments of the present utility model.

[0031] As Figure 1 and Figure 2As shown in the figure, the wiper bracket mounting structure according to an embodiment of the present utility model includes: a wiper bracket 1 and a shock tower 2. The wiper bracket 1 has a first fitting portion 121 and a second fitting portion 122. The first fitting portion 121 has a first fitting surface 1211 and abuts against the shock tower 2. The second fitting portion 122 has a second fitting surface 1221 and abuts against the shock tower 2. There is an included angle between the first fitting surface 1211 and the second fitting surface 1221.

[0032] For the wiper bracket mounting structure according to an embodiment of the present utility model, since both the first fitting surface 1211 and the second fitting surface 1221 abut against the shock tower 2, and there is an included angle between the first fitting surface 1211 and the second fitting surface 1221, when the wiper bracket 1 is stressed, the wiper bracket 1 can be simultaneously subjected to binding forces in different directions to resist the excitation caused by the movement of the wiper, preventing problems such as stress deformation and resonance of the wiper bracket 1, which is beneficial to reducing the vibration generated during wiper operation, reducing noise, and improving the driving experience of users.

[0033] It can be understood that compared with the structure in which only a single surface abuts against the shock tower 2, the wiper bracket mounting structure of the present application can improve the firmness of the installation of the wiper bracket 1 and the shock tower 2, that is, the first fitting surface 1211 and the second fitting surface 1221 can jointly limit the wiper bracket 1 and reduce the problem of the wiper bracket 1 shaking relative to the shock tower 2.

[0034] Specifically, the wiper bracket 1 includes a first connection section 11 and a second connection section 12. The first connection section 11 is connected to the second connection section 12. The first connection section 11 is adapted to install the wiper, and the second connection section 12 has a first fitting portion 121 and a second fitting portion 122.

[0035] In some embodiments, the wiper bracket 1 is detachably mounted on the shock tower 2, that is, the wiper bracket 1 is a loose-mounted part. Specifically, the wiper bracket mounting structure further includes a plurality of fasteners 3. The plurality of fasteners 3 are detachably passed through the second connection section 12 and the shock tower 2. Some of the fasteners 3 are arranged at intervals on the first fitting portion 121, and the other part of the fasteners 3 are arranged at intervals on the second fitting portion 122.

[0036] It can be understood that the number of the fasteners 3 and the fixing positions of the fasteners 3 can be designed according to the actual needs of the vehicle. For example, the number of the fasteners 3 and the fixing positions of the fasteners 3 can be adjusted to meet the vehicle collision performance, and can meet the stiffness requirements of the wiper bracket mounting structure, reduce the noise caused by the movement of the wiper, and have great flexibility and strong feasibility.

[0037] In one example, the fastener 3 is a threaded part, and the number of fasteners 3 can be 4 - 6. For example, 2 - 3 fasteners 3 are provided on the first fitting portion 121. 2 - 3 fasteners 3 are provided on the second fitting portion 122.

[0038] In some embodiments, the included angle between the first fitting surface 1211 and the second fitting surface 1221 is α, and 80° ≤ α ≤ 100°. It can be understood that the included angle between the first fitting surface 1211 and the second fitting surface 1221 can be any angle between 80° and 100°.

[0039] In one example, the included angle between the first fitting surface 1211 and the second fitting surface 1221 is 90°. It can be understood that the first fitting surface 1211 is orthogonal to the second fitting surface 1221, thereby further avoiding the shaking problem after the wiper bracket 1 and the shock tower 2 are installed.

[0040] Specifically, the shock tower 2 has a stepped portion 21. The stepped portion 21 has a first stepped surface 211 and a second stepped surface 212. The first stepped surface 211 is orthogonal to the height direction of the vehicle, and the second step is orthogonal to the front - rear direction of the vehicle. The first fitting surface 1211 fits with the first stepped surface 211, and the second fitting surface 1221 fits with the second stepped surface 212. By adopting the above - mentioned structural arrangement, the wiper bracket mounting structure of the embodiment of the present utility model is beneficial to improving the connection strength and stiffness between the wiper bracket 1 and the shock tower 2, can resist the excitation caused by the movement of the wiper, prevent the deformation of the wiper bracket 1 or cause resonance, and reduce noise.

[0041] In order to improve the dynamic stiffness of the wiper bracket 1, the thickness of the wiper bracket 1 can be appropriately increased. Specifically, the thickness of the wiper bracket 1 is greater than or equal to 6 mm. It can be understood that when the thickness of the wiper bracket 1 adopts the above - mentioned numerical range, the dynamic stiffness of the wiper bracket 1 can be greatly improved. Of course, the thickness of the wiper bracket 1 can be selected according to the design requirements. In the example of the present application, the wiper bracket 1 is a cast aluminum part, so that the thickness of the wiper bracket 1 can be designed to be thicker. Compared with designing the wiper bracket 1 as a sheet metal part in the present application, it is convenient to adjust the thickness of the wiper bracket 1 and it is easier to improve its dynamic stiffness.

[0042] For example, the thickness of the wiper bracket 1 can be 6 mm, 7 mm, 8 mm, 9 mm, 10 mm. The inventors of the present application found through experimental research that when the thickness of the wiper bracket 1 adopts the above - mentioned range, it can not only improve the dynamic stiffness of the wiper bracket 1 and reduce the resonance problem of the wiper bracket 1, but also reduce the overall weight of the wiper bracket mounting structure, which is beneficial to the lightweight design of the whole vehicle.

[0043] In one example, the wiper bracket 1 is an integrally cast part. For example, the wiper bracket 1 is a cast aluminum part. It can be understood that in the related art, the wiper bracket 1 adopts a sheet metal bending structure. When the thickness of the sheet metal part increases, it causes inconvenience in bending the sheet metal part. However, in the wiper bracket mounting structure of the embodiment of the present utility model, by designing the wiper bracket 1 as an integrally cast part, it is convenient to increase the thickness of the wiper bracket 1, the processing and manufacturing are simple, and the dynamic stiffness of the wiper bracket 1 is relatively high.

[0044] In some embodiments, as Figures 2 to 4 shown, the wiper bracket 1 further includes a reinforcing rib 13, and the reinforcing rib 13 is arranged on at least one of the first connecting section 11 and the second connecting section 12. It can be understood that the reinforcing rib 13 can improve the dynamic stiffness of the wiper bracket 1, can resist the excitation caused by the movement of the wiper, prevent the deformation of the wiper bracket 1 or cause resonance, and reduce noise.

[0045] Optionally, as Figure 3 and Figure 4 shown, the first connecting section 11 and the second connecting section 12 may both be provided with the reinforcing rib 13, and the reinforcing rib 13 is arranged on one side in the thickness direction of the wiper bracket 1 (the first connecting section 11 and the second connecting section 12) to improve the overall dynamic stiffness of the wiper bracket 1.

[0046] In other examples, the reinforcing rib 13 may be arranged on the side of the wiper bracket 1 adjacent to the shock absorber tower 2, or may be arranged on the side of the wiper bracket 1 away from the shock absorber tower 2. That is, the reinforcing rib 13 may be arranged on the front or back of the wiper bracket 1. Thereby, the dynamic stiffness of the wiper bracket 1 can be further improved, and the noise generated by the resonance of the wiper bracket 1 can be reduced.

[0047] A plurality of reinforcing ribs 13 may be provided, and the plurality of reinforcing ribs 13 are arranged at intervals and extend along the length direction of the wiper bracket 1. Specifically, the plurality of reinforcing ribs 13 are arranged at intervals along the width direction of the wiper bracket 1 and extend along the length direction of the wiper bracket 1. Thereby, the dynamic stiffness of the wiper bracket 1 can be further improved, and the noise generated by the resonance of the wiper bracket 1 can be reduced.

[0048] The front engine compartment assembly of another embodiment of the present utility model includes a wiper bracket mounting structure and a wiper. The wiper bracket mounting structure is the wiper bracket mounting structure of the present utility model. The wiper is connected to the first connecting section 11, and the shock absorber tower 2 is the front shock absorber tower 2.

[0049] According to the front cabin assembly of the embodiment of the present utility model, since both the first fitting surface 1211 and the second fitting surface 1221 are in contact with the shock tower 2, and there is an included angle between the first fitting surface 1211 and the second fitting surface 1221, when the wiper bracket 1 is stressed, the wiper bracket 1 can be simultaneously subjected to binding forces in different directions to resist the excitation caused by the movement of the wiper, preventing the problems of stress deformation and resonance of the wiper bracket 1, which is beneficial to reducing the vibration generated during wiper operation, reducing noise, and improving the driving experience of users.
