[0033] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0034] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0035] The first embodiment of the utility model provides a rear wiper installation structure, such as Figure 1-Figure 8 As shown, the rear wiper mounting structure includes a rear door 1, a wiper 2 and a rear wing 3. The rear door 1 is provided with a rear door glass mounting opening 4. The rear wing 3 is arranged above the rear door glass mounting opening 4 and connected to the rear door 1. The wiper 2 is installed in a first mounting space 5 between the rear door 1 and the rear wing 3. The bottom of the rear wing 3 is provided with a bottom plate 31 extending toward the rear door 1. The bottom plate 31 is connected to the rear door 1 and formed with a wiper working hole 32.

[0036] A rear door glass is installed at the rear door glass installation opening 4, and the wiper 2 acts on the rear door glass to scrape rainwater on the surface thereof. When the wiper 2 is in a non-working state, the wiper 2 is hidden in a first installation space 5 between the rear door 1 and the tail wing 3. When the wiper 2 is in use, the wiper arm 201 of the wiper 2 extends out of the first installation space 5 from the wiper working hole 32 and acts on the tailgate glass. The wiper 2 can be hidden in the first installation space 5 when not in use. Since the bottom of the rear wing 3 is provided with a bottom plate 31 extending toward the tailgate 1, a wiper working hole 32 is formed between the bottom plate 31 and the tailgate 1. The bottom plate 31 protects the wiper 2 to avoid damage to the wiper and prolong the service life of the wiper 2. The wiper 2 can only extend from the wiper working hole 32, that is, the wiper working hole 32 limits the operation of the wiper to avoid the wiper 2 moving in a direction away from the tailgate 1 and the wiper working hole 32 when a malfunction occurs.

[0037] At the same time, the wiper 2 is arranged in the first installation space 5 between the tailgate 1 and the rear wing 3 when not in operation, which can prevent the wiper 2 from being exposed outside the tailgate 1 and dust from accumulating on its surface; and can also improve the aesthetics of the vehicle.

[0038] In some embodiments, Figure 2 and Figure 6 As shown, the back door 1 includes a back door outer panel 101 and a back door inner panel 102, the wiper 2 is installed on the outer side of the back door outer panel 101, and the rear wiper installation structure also includes a wiper motor 7, the wiper motor 7 is installed in the second installation space 6 between the back door outer panel 101 and the back door inner panel 102, and the motor output shaft 701 of the wiper motor 7 passes through the back door outer panel 101 and is connected to the wiper 2. Specifically, the wiper 2 includes a wiper arm 201 and a wiper blade 202, the wiper motor 7 drives the wiper arm 201 to rotate, and then drives the wiper blade 202 connected to the wiper arm 201 to rotate, and the wiper blade 202 acts on the back door glass to scrape the rain on the surface. A part of the wiper motor 7 is always accommodated in the second installation space 6 formed by the back door inner panel 102 and the back door outer panel 101, saving space.

[0039] Furthermore, if Figure 1 , Figure 2 and Figure 6As shown, a concave cavity 8 recessed toward the rear of the vehicle is provided at a position on the rear wing 3 corresponding to the wiper 2. When the wiper 2 is in a non-working state, the wiper arm 201 and the wiper blade 202 are both hidden in the concave cavity 8 formed by the rear wing 3 and the rear door outer panel 102; when the wiper 2 is in a working state, the wiper arm 201 and the wiper blade 202 extend from the concave cavity 8 to act on the rear door glass surface. The concave cavity 8 and the wiper working hole 32 are arranged in parallel along the vehicle height direction and the two are interconnected, so that the wiper 2 can extend from the concave cavity 8 and the wiper working hole 32 when working. To avoid interference between the wiper blade 202 and the rear wing 3 during movement, the distance between the concave cavity 8 and the wiper 2 is at least 14 mm. Exemplarily, the distance between the concave cavity 8 and the wiper arm 201 of the wiper 2 is 14.5 mm.

[0040] Furthermore, a wiper nozzle 9 is mounted on the rear door outer panel 101, one end of which is disposed toward the rear door glass, and sprays glass water or cleaning fluid, etc., onto the rear door glass surface. The wiper nozzle 9 is always hidden in the concave cavity 8 formed by the rear wing 3 and the rear door outer panel 101, saving space and improving the aesthetics of the vehicle appearance.

[0041] In some embodiments, Figure 3-Figure 5 As shown, the rear wiper installation structure also includes a motor mounting plate 10, the motor mounting plate 10 is mounted on the back door inner plate 102, the wiper motor 7 is mounted on the motor mounting plate 10, and a motor avoidance hole 11 is opened on the motor mounting plate 10. Specifically, the motor mounting plate 10 is arranged between the back door outer plate 101 and the back door inner plate 102, and the upper and lower sides of the motor mounting plate 10 have connecting flanges 12, and the motor mounting plate 10 is welded to the back door inner plate 102 through the connecting flanges 12. The motor avoidance hole 11 is used to avoid the wiper motor 7, providing an avoidance space for the wiper motor 7, so that a part of the wiper motor 7 is accommodated in the second installation space 6, and the other part of the wiper motor 7 extends out of the second installation space 6 through the motor avoidance hole 11, so that the overall structure of the back door inner plate 102, the back door outer plate 101 and the motor mounting plate 10 is more compact, and the occupied space is reduced. At the same time, the motor avoidance hole 11 reduces the mass of the motor mounting plate 10, and achieves lightweight.

[0042] In some embodiments, the motor mounting plate 10 is also provided with a plurality of weight-reducing holes 13, the motor mounting plate 10 having a concave portion 1011 and a convex portion 1012, the weight-reducing holes 13 being provided in the concave portion 1011, and the shapes of the plurality of weight-reducing holes 13 are different. The weight-reducing holes 13 are provided on the motor mounting plate 10, so as to reduce the weight of the motor mounting plate 10, and thus facilitate lightweighting. Among them, the weight-reducing holes 13 provided on the motor mounting plate 10 cause strength loss to the motor mounting plate 10, and the concave portion 1011 provided on the motor mounting plate 10 can make up for the strength loss caused by the weight-reducing holes 13. The shape of the weight-reducing holes 13 can be determined according to the specifications of the motor mounting plate 10, for example, a larger strip-shaped weight-reducing hole 13 is provided at a position where the concave portion 1011 of the motor mounting plate 10 has a larger area, and a smaller circular weight-reducing hole 13 is provided at a position where the concave portion 1011 of the motor mounting plate 10 has a smaller area, which is conducive to making full use of the space of the motor mounting plate 10, thereby achieving lightweighting of the vehicle body.

[0043] Furthermore, a projection welding nut 14 is provided on one side of the motor mounting plate 10, and the first fastener is connected to the wiper motor 7 through the projection welding nut 14, and the projection welding nut 14 is distributed in a triangular shape. The projection welding nut 14 is provided on the motor mounting plate 10, and the installation position of the first fastener can be quickly determined by the projection welding nut 14 during installation, and the installation efficiency is high. Preferably, three projection welding nuts 14 are provided, and the three projection welding nuts 14 are distributed in a triangular shape, which is conducive to improving the stability of the installation of the wiper motor 7.

[0044] In some embodiments, Figure 2 As shown, a first reinforcement cavity 15 is formed between the motor mounting plate 10 and the back door inner plate 102, and a second reinforcement cavity 16 is formed between the motor mounting plate 10 and the back door outer plate 101. The motor mounting plate 10 and the back door outer plate 101, and the motor mounting plate 10 and the back door inner plate 102 are not arranged closely, but the motor mounting plate 10 divides the second installation space 6 into a first reinforcement cavity 15 and a second reinforcement cavity 16, wherein the first reinforcement cavity 15 is formed between the motor mounting plate 10 and the back door inner plate 102, and the second reinforcement cavity 16 is formed between the motor mounting plate 10 and the back door outer plate 101, thereby improving the connection strength and stability of the motor mounting plate 10 and the back door outer plate 101 and the back door inner plate 102, and improving the anti-dent performance of the back door outer plate 101.

[0045] The motor output shaft 701 of the wiper motor 7 passes through the rear door outer panel 101 and then extends into the concave cavity 8. Even though the bottom plate 31 of the rear wing 3 is provided and a smaller wiper working hole 32 (relative to the absence of the wiper working hole 32) is formed below the rear wing 3, the exposed sheet metal around the wiper motor output shaft 701 can still be observed when looking upward from the bottom of the rear wing 3, and the appearance is relatively poor. In order to improve the appearance of the rear wing 3 when viewed from above, the rear wiper installation structure also includes a wiper trim 17, such as Figure 7 and Figure 8 As shown, the wiper trim 17 is installed on the outer side of the back door outer panel 101. Specifically, the wiper trim 17 is snapped onto the back door outer panel 101. One of the wiper trim 17 and the back door outer panel 101 is provided with a buckle 18, and the other is provided with a clamping hole. The wiper trim 17 is connected to the back door outer panel 101 through the buckle 18 and the clamping hole, and is easy to install and remove. Exemplarily, the buckles 18 are distributed on both sides of the wiper trim 17, and each side has a buckle 18, which provides multiple installation points for the installation of the wiper trim 17, thereby improving the installation reliability of the wiper trim 17.

[0046] The wiper trim 17 is provided with a motor output shaft avoidance hole 19 for avoiding the motor output shaft 701 and a wiper nozzle avoidance hole 20 for avoiding the wiper nozzle 9. The motor output shaft avoidance hole 19 and the wiper nozzle avoidance hole 20 are respectively provided on the wiper trim 17 at the position of the motor output shaft 701 of the wiper motor 7 and the position of the wiper nozzle 9, so as to avoid the motor output shaft 701 and the wiper nozzle 9 respectively. The motor output shaft avoidance hole 19 and the wiper nozzle avoidance hole 20 are provided at the same time, so as to reduce the weight of the wiper trim 17 and achieve lightweight.

[0047] In some embodiments, a buffer 21 is further connected between the wiper trim 17 and the back door outer panel 101. The buffer 21 plays a buffering role, so that there is a gap between the wiper trim 17 and the back door outer panel 101, and the wiper trim 17 and the back door outer panel 101 do not directly contact each other, so as to prevent the wiper trim 17 from scratching the back door outer panel 101. If the wiper trim 17 is squeezed and contacts the back door outer panel 101, the buffer 21 can play a buffering role. Exemplarily, the buffer 21 is a sponge buffer or a rubber buffer.

[0048] Furthermore, the buffer 21 includes a strip buffer 211 distributed along the circumference of the wiper trim 17 and a block buffer 212 provided in the middle of the wiper trim 17. The strip buffer 211 is provided at the edges of the wiper trim 17, and the block buffer 212 is provided at the center of the wiper trim 17. By providing different buffers 21 at different positions of the wiper trim 17, the contact area between the buffer 21 and the wiper trim 17 is expanded, thereby improving the buffering effect.
