Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a segmented windshield wiper. Background Technology

[0002] Windshield wipers remove rainwater and other dirt by adhering tightly to the surface of the car's glass using a wiper blade. To achieve a good wiping effect, all parts of the wiper blade need to maintain uniform and stable contact pressure with the glass surface. Currently, most windshield wipers on the market adopt a one-piece or simple segmented structure, and their bracket components are mostly fixed. Their overall curvature is fixed at the factory. After such wipers are installed in the vehicle, their overall shape is relatively fixed and it is difficult to adjust them according to the curvature of the glass. When applied to glass surfaces with different curvatures, especially those with large curvature changes, it is easy to have problems with loose adhesion in some areas. This can lead to residual water stains, abnormal noises, or unclean wiping during the wiping process, affecting the driver's visibility and driving safety. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a segmented windshield wiper that can adjust the overall shape of the wiper according to the curvature of the vehicle glass, so that it fits the vehicle glass, effectively improving the cleaning effect and avoiding safety hazards.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a segmented windshield wiper, including a bracket assembly and a wiper blade. The wiper blade is installed at the lower end of the bracket assembly. The bracket assembly includes a main bracket for connecting with the wiper arm of the vehicle. Several secondary brackets are symmetrically arranged on both sides of the main bracket. The adjacent secondary brackets are connected to each other and to the main bracket by a rotating pivot. When the vehicle's glass has a large range, the rotating pivot changes the angle between the secondary bracket and the main bracket, and between adjacent secondary brackets, so that the wiper blade fits against the vehicle glass.

[0005] Furthermore, the auxiliary bracket is divided into a first bracket and a second bracket. The middle part of the first bracket is connected to the main bracket via a rotating pivot. The end of the first bracket away from the main bracket is connected to the middle part of the second bracket via a rotating pivot. A rubber strip clip is integrally provided on the end of the first bracket closer to the main bracket. Both ends of the second bracket are integrally provided with rubber strip clips. The wiper blade is sequentially inserted into each rubber strip clip, so that the wiper blade is installed at the lower end of the bracket assembly.

[0006] Furthermore, the rotating hub includes a vibrating sleeve and a rotating pin. The vibrating sleeve is a U-shaped plastic sleeve. The vibrating sleeve is installed in the middle of the first bracket and the second bracket respectively. The rotating pin passes through the main bracket, the vibrating sleeve and the first bracket in sequence to complete the connection between the main bracket and the first bracket. The rotating pin passes through the first bracket, the vibrating sleeve and the second bracket in sequence to complete the connection between the first bracket and the second bracket.

[0007] Furthermore, a first protective cover is installed on the first bracket, and a second protective cover is installed on the second bracket. The first protective cover, the second protective cover, and the main bracket are used to protect the first bracket, the second bracket, and the wiper blade.

[0008] Furthermore, the first bracket has a first mounting groove, and the first protective cover is installed by snapping into the first mounting groove with a hook. The second bracket has a second mounting groove, and the second protective cover is installed by snapping into the second mounting groove with a hook.

[0009] Furthermore, both sides of the first protective cover, the second protective cover, and the main support are integrally provided with a flow guide surface, which is used to guide the water flow direction and wind resistance.

[0010] Furthermore, a third protective cover is integrally provided on the end of the first bracket away from the main bracket. The rotating pin passes through the third protective cover, the vibration sleeve and the second bracket in sequence on the first bracket, so that the middle part of the first bracket and the second bracket are connected. The first bracket, the second bracket and the wiper blade are all located below the main bracket and the third protective cover.

[0011] Furthermore, both sides of the third protective cover and the main support are integrally provided with a flow guide surface, which is used to guide the water flow direction and wind resistance.

[0012] Compared with the prior art, the advantages of this utility model are that by using rotating pivots to achieve rotational connection between the main bracket and the secondary bracket, as well as between adjacent secondary brackets, a flexible bracket structure that can adapt to the curvature of the glass is constructed. When encountering vehicle glass with a large curvature, each component can rotate flexibly at the rotating pivot to adjust the angle between them, causing the entire bracket assembly to deform. This ensures that the wiper blade at the lower end can always maintain a tight and uniform fit with the curved surface of the glass, improving the wiping cleanliness and eliminating safety hazards caused by inadequate wiping. In addition, the first and second protective covers can effectively protect the first bracket, the second bracket, and the wiper blade, preventing them from being exposed to harsh environments such as sunlight and rain for a long time, slowing down the aging of the bracket and the wiper blade, and extending the service life of the wiper.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] Example 1: As Figures 1 to 4As shown in the figure, a segmented windshield wiper includes a bracket assembly and a wiper rubber strip 4. The wiper rubber strip 4 is installed at the lower end of the bracket assembly. The bracket assembly includes a main bracket 1, and the main bracket 1 is used to connect with the wiper arm of the vehicle. A number of sub-brackets are symmetrically arranged on both sides of the main bracket 1. The adjacent sub-brackets and between the sub-brackets and the main bracket 1 are all connected by a rotating pivot 3. Such a design forms a flexible bracket structure that can adapt to the curvature of the glass. When encountering a vehicle glass with a large curvature, each component can rotate flexibly at the rotating pivot 3 to adjust the angle between each other, causing the entire bracket assembly to deform, ensuring that the wiper rubber strip 4 at the lower end can always maintain a tight and uniform fit with the glass surface, overcoming the problems of local suspension or excessive pressure caused by the inability to adjust of the traditional fixed windshield wiper, improving the wiping cleanliness, and eliminating the safety hazards caused by incomplete wiping; The sub-bracket is divided into a first bracket 21 and a second bracket 22. The middle of the first bracket 21 is connected to the main bracket 1 through a rotating pivot 3. The first bracket 21 is provided with a first connection hole 214 at the end far from the main bracket 1. The first connection hole 214 is connected to the middle of the second bracket 22 through a rotating pivot 3. A rubber strip clip 211 is integrally provided at one end of the first bracket 21 close to the main bracket 1. Rubber strip clips 211 are integrally provided at both ends of the second bracket 22. The wiper rubber strip 4 is sequentially clamped into each rubber strip clip 211, so that the wiper rubber strip 4 is installed at the lower end of the bracket assembly. The wiper arm of the vehicle applies force to the main bracket 1, and the main bracket 1 divides the force into two parts and transmits them to the first brackets 21 on both sides respectively. The first bracket 21 divides the force into two parts and transmits it to the second bracket 22 and the rubber strip clip 211. The second bracket 22 divides the force into two parts and transmits it to the rubber strip clips 211 at both ends. The force provided by the wiper arm of the vehicle is evenly distributed to the entire wiper rubber strip 4 through layer-by-layer transmission; The rotating pivot 3 includes a shock sleeve 31 and a rotating pin 32. The shock sleeve 31 is a plastic sleeve in the shape of a "冂". The shock sleeve 31 is installed in the middle of the first bracket 21 or the second bracket 22. The rotating pin 32 sequentially passes through the connection hole 11 on the main bracket 1, the shock sleeve 31 and the second connection hole 213 on the first bracket 21 to complete the connection between the main bracket 1 and the first bracket 21. The rotating pin 32 sequentially passes through the first connection hole 214 on the first bracket 21, the shock sleeve 31 and the middle hole 222 on the second bracket 22 to complete the connection between the first bracket 21 and the second bracket 22. The rotating pivot 3 uses the cooperation of the "冂"-shaped shock sleeve 31 and the rotating pin 32, with a simple structure and low manufacturing cost. As a plastic part, the shock sleeve 31 can not only ensure the required movement clearance for connection to achieve flexible rotation, but also effectively buffer and absorb the vibration and impact generated during the wiping process, reducing wear and operating noise;A first protective cover 5 is installed on the first bracket 21, and a second protective cover 6 is installed on the second bracket 22. The first protective cover 5 and the second protective cover 6 are used to protect the first bracket 21, the second bracket 22, and the wiper blade 4, preventing them from being exposed to harsh environments such as sunlight and rain for a long time, slowing down the aging of the brackets and the wiper blade 4, and extending the service life of the wipers. A first mounting groove 212 is provided on the first bracket 21. The first protective cover 5 is inserted into the first mounting groove 212 by a hook 51 to realize the installation of the first bracket 21 and the first protective cover 5. The second bracket 22 has a second mounting groove 221. The second protective cover 6 is inserted into the second mounting groove 221 via a hook 51 to achieve the installation of the second bracket 22 and the second protective cover 6. The first protective cover 5, the second protective cover 6, and both sides of the main bracket 1 are integrally provided with a guide surface 52. The guide surface 52 is used to guide the water flow direction and wind resistance. The guide surface 52 can effectively guide the airflow when the vehicle is traveling at high speed, reduce wind resistance and wind noise, and prevent the wipers from abnormally lifting or shaking in strong winds, ensuring the smoothness and reliability of the wiping process.

[0016] Example 2: Figure 5 and Figure 6 As shown, several auxiliary supports are symmetrically arranged on both sides of the main support 1. The auxiliary supports are divided into a first support 21 and a second support 22. The middle part of the first support 21 is connected to the main support 1 through a rotating pivot 3. A third protective cover 7 is integrally provided on the end of the first support 21 away from the main support 1. The third protective cover 7 is provided with a third connecting hole 71. The rotating pin 32 passes through the connecting hole 71, the vibrating sleeve 31, and the middle hole 222 on the second support 22 in sequence, so that the middle parts of the first support 21 and the second support 22 are connected. The rotating pin 32 passes through the connecting hole 11 on the main support 1, the vibrating sleeve 31, and the second connecting hole 213 on the first support 21 in sequence, completing the connection between the main support 1 and the second support 22. The first bracket 21 is connected, and a rubber strip clip 211 is integrally provided on one end of the first bracket 21 near the main bracket 1. Both ends of the second bracket 22 are integrally provided with rubber strip clips 211. The wiper blade 4 is sequentially inserted into each rubber strip clip 211, so that the wiper blade 4 is installed at the lower end of the bracket assembly. The first bracket 21, the second bracket 22 and the wiper blade 4 are all located below the main bracket 1 and the third protective cover 7. The main bracket 1 and the third protective cover 7 are used to protect the first bracket 21, the second bracket 22 and the wiper blade 4. The two sides of the third protective cover 7 and the two sides of the main bracket 1 are symmetrically provided with guide surfaces 52, which are used to guide the water flow direction and wind resistance.

[0017] In Examples 1 and 2, the wiper blade 4 is made of a soft material and has a steel strip inside.
