Wiper assembly, control method and vehicle

Abstract

The present application discloses a wiper assembly, a control method, and a vehicle, belonging to the technical field of wipers. The wiper assembly shields the notch of a first slot section of a ditch by a first shielding member, and shields the notch of a second slot section of the ditch by a second shielding member. When the wiper arm is in use, the second shielding member does not shield the notch of the second slot section, thereby preventing the second shielding member from interfering with the wiper arm, allowing the wiper arm to enter the second slot section, ensuring that the wiper arm can wipe a larger area. When the wiper arm is not in use, the wiper arm is located in the first slot section and the first shielding member shields the notch of the first slot section, preventing the user from seeing the first slot section and the wiper arm therein. In addition, when the wiper arm is not in use, the notch of the second slot section is shielded by the second shielding member, preventing the user from seeing the second slot section. This design not only improves the aesthetics of the vehicle, but also reduces the requirement of the wiper arm for the depth of the ditch, so that the depth of the ditch can be designed to accommodate the wiper arm.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall 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 and movement status of 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 specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] In addition, in the present invention, descriptions such as "first" and "second" are for descriptive purposes only and should not 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 such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such 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 generally referred to as the X direction or longitudinal direction, the width direction of a vehicle is referred to as the Y direction or transverse direction, and the height direction of a vehicle is referred to as the Z direction or vertical direction. The interpretations of the relevant directional expressions in the following embodiments can refer to the above content.

[0037] In traditional solutions, to ensure the shielding effect of the spoiler over the wiper arm and enhance the aesthetics of the vehicle's rear, the spoiler is hollowed out deeply, allowing the wiper arm to extend as far as possible into the spoiler to enhance the shielding effect. While this design can conceal the wiper arm to a certain extent and enhance the aesthetics of the vehicle's rear, the deep hollowing significantly impacts the mounting structure and strength of the spoiler and tailgate. To ensure the mounting structure and strength of the spoiler and tailgate, the hollowing must be designed to be short. A longer design would not ensure the strength of the connection between the spoiler and tailgate, thus preventing the wiper arm from being designed longer, affecting the wiper arm's wiping area. Furthermore, with this design, the wiper arm and the hollowing area are still visible when looking upward from the height of the vehicle, which does not significantly improve the aesthetics.

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

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

[0040] like Figures 1 to 8As shown, the wiper assembly 100 is mounted on the vehicle body and includes a spoiler 110, a rear windshield 120, a wiper arm 130, a wiper drive mechanism 140, a first shielding member 150, a second shielding member 160, and a shielding member drive mechanism 170. The spoiler 110 and the rear windshield 120 are both mounted on the vehicle body, and the spoiler 110 and the rear windshield 120 together form an avoidance groove 100a, which has a first groove section 110b and a second groove section 110c that are connected. The wiper arm 130 is driven by the wiper drive mechanism 140 to switch between a starting position in the first groove section 110b and a maximum position in the second groove section 110c. The first shielding member 150 is mounted 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 slot opening of the second slot section 110c and an opening position for opening the slot opening of the second slot section 110c; wherein, when the wiper arm 130 is in the starting position, the first shielding member 150 shields the slot opening of the first slot section 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, reducing the air resistance generated when the vehicle is traveling at high speeds. The brake lights of the vehicle 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 detent are both installed on the vehicle body. The spoiler 110 can provide support for the rear windshield 120. The structures of the spoiler 110 and the rear windshield 120 and the specific installation methods are various and are 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 not in use, the wiper arm 130 is located in the avoidance groove 100a and is blocked by the spoiler 110, improving 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. 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, thereby causing the wiper blade to scrape the surface of the rear windshield 120 and 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. This means that the wiper arm 130 drives the first shielding member 150 in motion. The first shielding member 150 blocks the notch of the first slot section 110b, thereby shielding the wiper arm 130 within the first slot section 110b. When the wiper arm 130 is in its initial position, the first shielding member 150 blocks the notch of the first slot section 110b.

[0044] The second shielding member 160 is used to cover or open the notch of the second slot section 110c. Specifically, the second shielding member 160 can cover or open 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, or other methods to place the second shielding member 160 in the covering position or the open position, which is not limited in this 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. 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, thereby preventing 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 slot of the second slot section 110c is covered by the second shielding member 160, so that the user cannot see the second slot 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 the 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 rotates along with the rotating shaft 162 around the axis of the rotating shaft 162, thereby allowing the shielding plate 161 to be positioned in a shielding position, covering the notch of the second slot segment 110c, or in an open position, not covering the notch of the second slot segment 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. This ensures that when the shielding plate 161 is in the open position, it is away from the rear windshield 120, preventing the shielding plate 161 from 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 at 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 engaged 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 mounted on the rotating shaft 162 of the second shielding member 160, and the transmission gear 173 and the output gear 172 are meshed. With this 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 trough 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 slot segment 110c. When the shielding plate 161 is located in the shielding position of the slot opening of the second slot segment 110c, the rotating shaft 162 and the shielding member driving mechanism 170 are blocked by the shielding plate 161, and the rotating shaft 162 and the shielding member driving mechanism 170 cannot be seen from the outside. This 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 driving mechanism 140 is a motor. The output end of the wiper driving mechanism 140 is fixedly connected to the rotating shaft 131 of the wiper arm 130. The wiper driving 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 to 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. With this design, 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 about 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 engaged 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. During the process of the wiper arm 130 rotating 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. Furthermore, before the wiper arm 130 rotates to the maximum position, the second shielding member 160 rotates to the open position. With this design, during the process of the wiper arm 130 rotating 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. Furthermore, 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, thereby simplifying 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 100 a. 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, a portion of the second driving member 141 of the wiper driving mechanism 140 is located inside the spoiler 110 , thereby reducing 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, and the first shielding member 150 is mounted on the outside of the wiper arm 130 through the receiving groove 150a. 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 shield 150 has a receiving slot 150a. The wiper arm 130 extends into the first shield 150 through the notch of the receiving slot 150a and is fixedly connected to the first shield 150. The wiper blade of the wiper arm 130 is not located within the receiving slot 150a, but is located outside the receiving slot 150a to ensure that the wiper blade contacts and cleans the rear windshield 120. With this design, the first shield 150 is positioned over the wiper arm 130. The first shield can be beautified with a design such as a pattern or color, thereby enhancing the aesthetics of the wiper assembly 100. Furthermore, the first shield 150 protects 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 in the starting position, the projection of the first covering 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 covering member 160 is in the shielding position, the projection of the second covering 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 in the initial position, the spoiler 110 shields the first shielding member 150 along the length of the vehicle body. When the second shielding member 160 is in the shielding position, the spoiler 110 shields the second shielding member 160 along the length of the vehicle body. This design prevents the lower ends of the first shielding member 150 and the second shielding member 160 from extending beyond the spoiler 110. Therefore, the first shielding member 150 and the second shielding member 160 are not visible to people outside the vehicle along the length 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, an 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 the on signal of the wiper drive mechanism 140, controlling the shielding member driving mechanism 170 to drive the second shielding member 160 to be in the open position; responding to the off signal of the wiper drive mechanism 140, controlling the shielding member driving mechanism 170 to drive the second shielding member 160 to be in the closed position.

[0066] When the wiper drive mechanism 140 of the wiper arm 130 is activated, it drives the wiper arm 130 to rotate back and forth about the rotation axis 131 of the wiper arm 130, causing the wiper blade of the wiper arm 130 to reciprocate and wipe the rear windshield 120, thereby cleaning the rear windshield 120. As the wiper drive mechanism 140 moves, the wiper arm 130 rotates, necessitating the control of the shielding member drive mechanism 170 to drive the second shielding member 160 to the open position to prevent the second shielding member 160 from interfering with the rotation of the wiper arm 130 into the second groove section 110c. After the wiper drive mechanism 140 is turned off, the wiper arm 130 is located within the first slot section 110b. The wiper arm 130 stops moving, and the first shielding plate 161 blocks the notch of the first slot section 110b. Therefore, it is necessary to control the shielding member driving mechanism 170 to drive the second shielding member 160 to move to the closed position, blocking 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 remains in the open position. When the wiper arm 130 stops moving, the second shielding member 160 returns to the closed position.

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