DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0034] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] In the field of vehicles, the length direction of a vehicle is usually referred to as the X direction or longitudinal direction, the width direction of a vehicle is called the Y direction or lateral direction, and the height direction of a vehicle is called the Z direction or vertical direction. The interpretations of the relevant directional expressions in the following embodiments can all refer to the above content.

[0037] In the traditional solution, in order to ensure the shielding effect of the spoiler compared to the wiper arm and improve the aesthetics of the back shape of the vehicle, the hollowing depth of the spoiler is deep, so that the wiper arm can be extended into the spoiler as much as possible to improve the shielding effect. Although this design can hide the wiper arm to a certain extent and increase the aesthetics of the back of the vehicle, after such a design, due to the deep hollowing depth, it has a great impact on the installation and fixing structure and strength of the spoiler and the back door. In order to ensure the installation and fixing structure and strength of the spoiler and the back door, the hollowing length can only be designed to be shorter. If it is designed to be longer, the connection strength of the spoiler and the back door installation and fixing structure cannot be guaranteed, so that the length of the wiper arm cannot be designed to be longer, affecting the wiping area of ​​the wiper arm. In addition, after such a design, when looking up along the height direction of the vehicle, the wiper arm can still be seen, and the hollowing area can be seen, which does not improve the aesthetics much.

[0038] Therefore, in the related art, there is a technical problem that the spoiler is hollowed out to a deeper depth to shield the wiper and improve the aesthetics, which limits the length of the wiper arm. The embodiment of the present application provides a wiper assembly, a control method and a vehicle, which can at least solve the technical problem of the spoiler being hollowed out to a certain extent.

[0039] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0040] like Figures 1 to 8As shown, the wiper assembly 100 is installed on the vehicle body, and includes a spoiler 110, a rear windshield 120, a wiper arm 130, a wiper driving mechanism 140, a first shielding member 150, a second shielding member 160 and a shielding member driving mechanism 170. The spoiler 110 and the rear windshield 120 are both installed on the vehicle body, and the spoiler 110 and the rear windshield 120 are combined to form an avoidance groove 100a, and the avoidance groove 100a has a first groove section 110b and a second groove section 110c that are connected; the wiper arm 130 is driven by the wiper driving mechanism 140 to switch between a starting position located in the first groove section 110b and a maximum position located in the second groove section 110c; the first shielding member 150 is installed on the wiper arm 130; the second shielding member 160 is installed on the wiper arm 130; The second shielding member 160 is driven by a shielding member driving mechanism 170, and switches between a shielding position for shielding the notch of the second slot segment 110c and an opening position for opening the notch of the second slot segment 110c; wherein, when the wiper arm 130 is in the starting position, the first shielding member 150 shields the notch of the first slot segment 110b, and the second shielding member 160 is in the shielding position; when the wiper arm 130 is in the maximum position, the second shielding member 160 is in the opening position.

[0041] The spoiler 110 can disturb the airflow and reduce the air resistance generated when the vehicle is traveling at high speed. The brake light of the car can be installed on the spoiler 110. The spoiler 110 is located at the upper end of the rear windshield 120. The rear windshield 120 and the deflector are both installed on the vehicle body. The spoiler 110 can provide support for the rear windshield 120. The structure of the spoiler 110 and the rear windshield 120 and the specific installation method are various and known to those skilled in the art, and are not limited here. A avoidance groove 100a is formed between the spoiler 110 and the rear windshield 120. The notch of the avoidance groove 100a is downward, and the avoidance groove 100a extends along the width direction of the vehicle body. When the wiper arm 130 is not in use, it is located in the avoidance groove 100a and is shielded by the spoiler 110 to improve the aesthetics. Specifically, the avoidance groove 100a has two connected sections, namely the first groove section 110b and the second groove section 110c. The first groove section 110b and the second groove section 110c are arranged in sequence along the width direction of the vehicle body. When the wiper arm 130 is not in use, it is located in the first groove section 110b.

[0042] The wiper arm 130 and the wiper driving mechanism 140 are transmission-connected, and the wiper blade of the wiper arm 130 is in contact with the surface of the rear windshield 120. The wiper driving mechanism 140 drives the wiper arm 130 to rotate back and forth around the rotating shaft 131 of the wiper arm 130, so that the wiper blade scrapes the surface of the rear windshield 120 to clean the surface of the rear windshield 120.

[0043] The first shielding member 150 is fixedly connected to the wiper arm 130, and moves synchronously with the wiper arm 130, that is, the wiper arm 130 drives the first shielding member 150 to move. The function of the first shielding member 150 is to shield the notch of the first slot section 110b, and then shield the wiper arm 130 located in the first slot section 110b. When the wiper arm 130 is located at the initial position, the first shielding member 150 is in a state of shielding the notch of the first slot section 110b.

[0044] The second shielding member 160 is used to shield the notch of the second slot section 110c or to open the notch of the second slot section 110c. Specifically, the second shielding member 160 can shield the notch of the second slot section 110c or not shield the notch of the second slot section 110c under the drive of the shielding member driving mechanism 170. The shielding member driving mechanism 170 can drive the second shielding member 160 to slide, rotate, etc., so that the second shielding member 160 is located in the shielding position or the open position, which is not limited in the present application.

[0045] When the wiper arm 130 is in the initial position, the first shielding member 150 blocks the notch of the first slot section 110b, and the second shielding member 160 is in the shielding position, and the first shielding member 150 and the second shielding member 160 work together to shield the notch of the avoidance slot 100a; when the wiper arm 130 is in the maximum position, the second shielding member 160 is in the open position without shielding the notch of the second slot section 110c, avoiding the wiper arm 130, so that the wiper arm 130 can be in the maximum position, that is, in the second slot section 110c.

[0046] The wiper assembly 100 shields the notch of the first slot section 110b of the avoidance slot 100a through the first shielding member 150, and shields the notch of the second slot section 110c of the avoidance slot 100a through the second shielding member 160. When the wiper arm 130 is in use, the second shielding member 160 does not shield the notch of the second slot section 110c, so as to prevent the second shielding member 160 from interfering with the wiper arm 130, so that the wiper arm 130 can enter the second slot section 110c, ensuring that the wiper arm 130 can wipe a larger area; when the wiper arm 130 is not in use, the wiper arm 130 is located in the first slot section 110b and the first shielding member 150 shields the notch of the first slot section 110b, so that the user cannot see the first slot section 110b and The wiper arm 130 therein; in addition, when the wiper arm 130 is not in use, the notch of the second groove section 110c is shielded by the second shielding member 160, so that the user cannot see the second groove section 110c. This design not only improves the aesthetics of the vehicle, but also reduces the requirement of the wiper arm 130 for the depth of the avoidance groove 100a, so that the depth of the avoidance groove 100a is designed to accommodate the wiper arm 130, reducing the influence of the depth of the avoidance groove 100a on the strength of the spoiler 110, etc. After this design, while ensuring aesthetics, the avoidance groove 100a can be designed to be longer, thereby making the length of the wiper arm 130 longer, increasing the wiping area of ​​the wiper arm 130, and improving the wiping efficiency.

[0047] In some embodiments, the second shielding member 160 includes a shielding plate 161 and a rotating shaft 162 fixed on the shielding plate 161, the shielding plate 161 is used to shield the slot of the second slot section 110c, the rotating shaft 162 is arranged along the width direction of the vehicle body, and the rotating shaft 162 is rotatably connected to the spoiler 110; the shielding member driving mechanism 170 drives the rotating shaft 162 to rotate.

[0048] The axis of the rotating shaft 162 is arranged along the width direction of the vehicle body, that is, the axis of the rotating shaft 162 is parallel to the width direction of the vehicle body. The rotating shaft 162 is fixedly connected to the shielding plate 161. When the shielding member driving mechanism 170 drives the rotating shaft 162 to rotate, the shielding plate 161 will rotate around the axis of the rotating shaft 162 along with the rotating shaft 162, so that the shielding plate 161 can be located in a shielding position that shields the notch of the second slot section 110c, or in an open position that does not shield the notch of the second slot section 110c. It should be noted that the rotating shaft 162 is arranged on the side of the shielding plate 161 away from the rear windshield 120, so that when the shielding plate 161 is in the open position, the shielding plate 161 is away from the rear windshield 120, so as to avoid the shielding plate 161 interfering with the movement of the wiper arm 130.

[0049] In some embodiments, such as Figure 8 As shown, when the second shielding member 160 is located at the open position, the second shielding member 160 is located in the second slot section 110 c and is attached to the inner wall of the spoiler 110 .

[0050] like Figure 5 As shown, in some embodiments, the shielding member driving mechanism 170 includes a first driving member 171, an output gear 172 and a transmission gear 173. The first driving member 171 is installed on the spoiler 110, the output gear 172 is installed on the output end of the first driving member 171, and the transmission gear 173 is fixedly connected to the rotating shaft 162, and the output gear 172 is meshed with the transmission gear 173.

[0051] The first driving member 171 is fixedly connected to the spoiler 110, and the output end of the first driving member 171 is fixedly connected to the output gear 172, and the first driving member 171 drives the output gear 172 to rotate. The transmission gear 173 is installed on the rotating shaft 162 of the second shielding member 160, and the transmission gear 173 and the output gear 172 are meshed. After such a design, the rotation of the first driving member 171 can drive the transmission gear 173 to rotate, thereby driving the second shielding member 160 to rotate, so that the shielding plate 161 can be located in a shielding position that shields the notch of the second slot section 110c, or in an open position that does not shield the notch of the second slot section 110c. It should be noted that the output gear 172 and the rotating shaft 162 are coaxially arranged.

[0052] In some embodiments, the rotating shaft 162 and the shielding member driving mechanism 170 are both disposed on a side of the shielding plate 161 facing the bottom of the second slot section 110 c.

[0053] That is to say, the rotating shaft 162 and the shielding member driving mechanism 170 are both arranged between the shielding plate 161 and the bottom of the second groove section 110c. When the shielding plate 161 is located in the shielding position of shielding the groove opening of the second groove section 110c, the rotating shaft 162 and the shielding member driving mechanism 170 are shielded by the shielding plate 161, and the rotating shaft 162 and the shielding member driving mechanism 170 are not visible to the outside world. Such a design helps to improve the aesthetics of the wiper assembly 100.

[0054] In some embodiments, the rotating shaft 131 of the wiper arm 130 is located in the middle of the avoidance groove 100a and is rotatably connected to the spoiler 110. The wiper drive mechanism 140 is a motor. The output end of the wiper drive mechanism 140 is fixedly connected to the rotating shaft 131 of the wiper arm 130. The wiper drive mechanism 140 drives the wiper arm 130 to rotate.

[0055] like Figure 4As shown, in some embodiments, the wiper drive mechanism 140 includes a second driving member 141, a first gear 142 and a second gear 143, the first gear 142 and the second gear 143 are meshed, the second gear 143 is fixedly connected to the rotating shaft 131 of the wiper arm 130, and the second driving member 141 is installed on the spoiler 110 to drive the first gear 142 to rotate; the shielding member driving mechanism includes a meshing first bevel gear 174 and a second bevel gear 175, the first bevel gear 174 is fixedly connected to the first gear 142, and the second bevel gear 175 is installed on the second shielding member 160.

[0056] It should be noted that the second bevel gear 175 is mounted on the rotating shaft 162 of the second shielding member 160, the first gear 142 and the second bevel gear 175 are coaxially arranged, the second bevel gear 175 and the rotating shaft 162 are coaxially arranged, the axes of the first gear 142 and the second gear 143 are parallel, and the second gear 143 is coaxially arranged with the rotating shaft 131 of the wiper arm 130. The second gear 143 is fixedly connected with the rotating shaft 131 of the wiper arm 130, the first gear 142 and the second gear 143 are meshed, and the second driving member 141 is mounted on the spoiler 110 to drive the first gear 142 to rotate. After such a design, the rotation of the second driving member 141 will drive the first gear 142 to rotate, and at the same time drive the second gear 143 to rotate, thereby driving the wiper arm 130 to rotate around the rotating shaft 131, so that the wiper arm 130 can wipe the surface of the rear windshield 120. The first bevel gear 174 is fixed on the first gear 142, and the second bevel gear 175 is not only meshed with the first bevel gear 174, but also fixedly connected to the rotating shaft 162 of the second shielding member 160. Therefore, the first bevel gear 174 will rotate with the first gear 142 and drive the second bevel gear 175 to rotate, thereby driving the second shielding member 160 to rotate, so that the second shielding member 160 can be located in the shielding position or the open position. With this design, the wiper arm 130 and the second shielding member 160 move synchronously. When the wiper arm 130 rotates from the starting position to the maximum position, the second shielding member 160 rotates synchronously, and the second shielding member 160 rotates from the shielding position to the open position, and before the wiper arm 130 rotates to the maximum position, the second shielding member 160 rotates to the open position; with this design, when the wiper arm 130 rotates from the maximum position to the starting position, the second shielding member 160 rotates synchronously, and the second shielding member 160 rotates from the open position to the shielding position, and after the wiper arm 130 rotates out of the second groove section 110c, the second shielding member 160 rotates to the open position. The wiper arm 130 and the second shielding member 160 are driven by the same driving member, and the wiper arm 130 and the second shielding member 160 move synchronously, which simplifies the structure of the wiper assembly 100.

[0057] In some embodiments, the wiper drive mechanism 140 and the shielding member drive mechanism 170 are both located in the avoidance groove 100a. With this design, the wiper drive mechanism 140 and the shielding member drive mechanism 170 can be shielded by the first shielding member 150 and / or the second shielding member 160, thereby improving the aesthetics of the wiper assembly 100.

[0058] In some embodiments, part of the second driving member 141 of the wiper driving mechanism 140 is located inside the spoiler 110 , so as to reduce the space occupied by the wiper driving mechanism 140 in the avoidance groove 100 a .

[0059] like Figure 7 As shown, in some embodiments, the first shielding member 150 has a receiving groove 150a, the first shielding member 150 is sleeved on the outside of the wiper arm 130 through the receiving groove 150a, and the wiper blade of the wiper arm 130 extends out of the receiving groove 150a through the notch of the receiving groove 150a.

[0060] The first shielding member 150 has a receiving groove 150a, and the wiper arm 130 extends into the first shielding member 150 through the notch of the receiving groove 150a and is fixedly connected to the first shielding member 150. The wiper blade of the wiper arm 130 is not located in the receiving groove 150a, but is located outside the receiving groove 150a to ensure that the wiper blade contacts the rear windshield 120 to clean the rear windshield 120. With this design, the first shielding member 150 is covered on the wiper arm 130, and patterns, colors, etc. can be designed on the first shielding cover to beautify it, thereby improving the aesthetics of the wiper assembly 100. On the other hand, the first shielding member 150 can protect the wiper arm 130 located inside.

[0061] In some embodiments, the wiper arm 130 is snapped into the first shielding member 150 .

[0062] like Figure 7 and Figure 8 As shown, in some embodiments, when the wiper arm 130 is located in the starting position, the projection of the first shielding member 150 toward the spoiler 110 is entirely located on the spoiler 110 along the length direction of the vehicle body; and / or, when the second shielding member 160 is located in the shielding position, the projection of the second shielding member 160 toward the spoiler 110 is entirely located on the spoiler 110 along the length direction of the vehicle body.

[0063] That is, when the wiper arm 130 is at the initial position, the spoiler 110 shields the first shielding member 150 along the length direction of the vehicle body; when the second shielding member 160 is at the shielding position, the spoiler 110 shields the second shielding member 160 along the length direction of the vehicle body. With this design, the lower ends of the first shielding member 150 and the second shielding member 160 do not extend out of the spoiler 110, and the first shielding member 150 and the second shielding member 160 are not visible to people outside the vehicle along the length direction of the vehicle body, thereby improving the aesthetics of the wiper assembly 100.

[0064] In some embodiments, the second driving component 141 and the first driving component 171 are both motors.

[0065] Based on the same inventive concept, the embodiment of the present application also provides a method for controlling a wiper assembly 100, which is implemented based on the above-mentioned wiper assembly 100. The control method includes: responding to an on signal of the wiper drive mechanism 140, controlling the shielding member driving mechanism 170 to drive the second shielding member 160 to be located in an on position; responding to a off signal of the wiper drive mechanism 140, controlling the shielding member driving mechanism 170 to drive the second shielding member 160 to be located in a off position.

[0066] After the wiper driving mechanism 140 of the wiper arm 130 is started, the wiper driving mechanism 140 will drive the wiper arm 130 to reciprocate around the rotating shaft 131 of the wiper arm 130, so that the wiper blade of the wiper arm 130 reciprocates to wipe the rear windshield 120, thereby cleaning the rear windshield 120. When the wiper driving mechanism 140 moves, the wiper arm 130 will rotate, so it is necessary to control the shielding member driving mechanism 170 to drive the second shielding member 160 to be located in the open position, so as to prevent the second shielding member 160 from interfering with the wiper arm 130 rotating into the second groove section 110c. After the wiper driving mechanism 140 is turned off, the wiper arm 130 is located in the first slot section 110b, the wiper arm 130 stops moving, and the first shielding plate 161 shields the notch of the first slot section 110b, so it is necessary to control the shielding member driving mechanism 170 to drive the second shielding member 160 to move to the closed position to shield the notch of the second slot section 110c to ensure the aesthetics of the wiper assembly 100. When the wiper arm 130 moves, the second shielding member 160 is always in the open position, and when the wiper arm 130 stops moving, the second shielding member 160 is in the closed position again.

[0067] Based on the same inventive concept, the embodiment of the present application further provides a vehicle, which includes the above-mentioned wiper assembly 100. Since the vehicle includes the above-mentioned wiper assembly 100, it naturally has all the beneficial effects of the wiper assembly 100, which will not be described in detail here.
