Description

Technical Field

[0001] This utility model relates to the field of wiper lever technology, and in particular to a wiper control lever based on the type of dirt. Background Technology

[0002] The wiper stalk, usually located on the right side of the steering wheel, is the core component controlling the vehicle's windshield wipers. It offers multiple modes to adapt to different weather conditions: OFF (off), INT (intermittent wiping, suitable for light rain), LO (low-speed continuous wiping, suitable for moderate rain), and HI (high-speed continuous wiping, suitable for heavy rain). In addition, the intermittent mode allows for manual single wiping, while pulling the stalk towards the driver and holding it sprays windshield washer fluid and simultaneously wipes away dirt, ensuring a clear windshield and safe driving visibility.

[0003] Currently, most vehicle models use a fixed-installation wiper stalk, with neither its length nor the angle of the actuating end (operating head) being adjustable. Drivers vary greatly in size (height, arm length, seating posture), and the fixed length may require some drivers (such as shorter or taller individuals) to excessively extend or bend their arms for comfortable operation. This is especially problematic when using intermittent wipers, spraying water, or switching to higher speeds. The fixed angle cannot match the natural wrist angles of different drivers, and prolonged or frequent operation (such as repeated adjustments during heavy rain) may lead to wrist and arm discomfort or even fatigue, affecting driving concentration. In situations requiring urgent wiper adjustments (such as quickly switching to HI mode in a sudden downpour), the awkward operating posture may increase the risk of operational errors or distract the driver from road conditions, posing a safety hazard. Therefore, those skilled in the art have provided a wiper control stalk based on the type of dirt to address the problems mentioned in the background. Utility Model Content

[0004] 1. Technical Solution

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a wiper control lever based on the type of dirt, comprising:

[0007] The lever structure includes a connecting lever, a sleeve sleeved on the outside of the connecting lever, an operating head located on one side of the sleeve, side blocks symmetrically distributed at one end of the operating head, and a central retaining sleeve located at one end of the sleeve and inside the side blocks.

[0008] Adjustment structure one includes an installation groove inside the upper end of the sleeve, a rotating shaft rotatably installed inside the installation groove, a gear sleeved on the outside of the rotating shaft, a toothed plate one and a toothed plate two located on both sides of the installation groove and meshing with the gear, a support ring one located at the lower end of the toothed plate one, a spring one located between the support ring one and the inner wall of the lower end of the installation groove one, a pressure rod one located at the upper end of the toothed plate one, a pressure block located at the upper end of the pressure rod one and sleeved on the outside of the sleeve, a slot one equidistantly distributed on the outer wall of the upper end of the connecting lever one, and a locking block one located at the lower end of the toothed plate two and locked inside the slot one.

[0009] as well as;

[0010] Adjustment structure two includes a mounting shaft rotatably installed inside the central sleeve and connected to the side blocks at both ends; a slot two with a ring array distributed on the outer wall of the mounting shaft; a stroke groove opened inside the upper end of the central sleeve; a pressure rod two slidably installed inside the stroke groove; and a locking block two located at the lower end of the pressure rod two and inserted into the slot two.

[0011] Furthermore, the connecting lever has grooves at both ends, and the sleeve has balls rotatably mounted on the outer walls at both ends that roll and fit against the inner walls of the grooves.

[0012] Specifically, the sleeve slides on the outer wall of the ball, which provides sliding guidance for the sleeve, and the sleeve slides stably with low friction and conveniently.

[0013] Furthermore, guide rails are provided on both inner walls of the mounting groove, and sliders that are slidably mounted on the outer wall of the guide rails are provided at opposite ends of the toothed plate one and toothed plate two.

[0014] Specifically, when toothed plate one and toothed plate two move longitudinally, they slide against the outer wall of the guide rail via a slider, thus providing longitudinal sliding guidance for toothed plate one and toothed plate two.

[0015] Furthermore, a latex sleeve is fitted onto the outer wall of the operating head, and the outer wall of the latex sleeve is provided with anti-slip texture;

[0016] Specifically, the latex sleeve enhances hand comfort during contact, while the anti-slip texture improves friction and grip during operation.

[0017] Furthermore, a positioning rod is provided at the lower end of the support ring, which is located inside the spring, and a positioning cylinder is provided on the inner wall of the lower end of the mounting groove, which is sleeved on the outer wall of the positioning rod and located inside the spring.

[0018] Specifically, when spring 1 extends or retracts longitudinally, the positioning rod slides inside the positioning cylinder to guide spring 1 during the extension and retraction process, preventing spring 1 from shifting outwards.

[0019] Furthermore, a support ring is sleeved on the outer wall of the upper end of the second pressure rod, and a spring is sleeved on the outside of the second pressure rod between the second support ring and the central sleeve. A pull rod is provided at the upper end of the second pressure rod.

[0020] Specifically, by pulling the lever upwards with your fingers, the pressure rod two and the support ring two exert a pulling force on the spring two, causing the elastic support pressure rod two to drive the locking block two to insert into the slot two, thus fixing the mounting shaft.

[0021] 2. Beneficial effects

[0022] Compared with existing technologies, the advantages of this utility model are:

[0023] This invention features a connecting lever located on one side below the steering wheel. Driving with the lever adjusts and controls the windshield wipers, enabling them to clean rainwater and dirt. A sleeve housing fitted to the outer side of the lever allows for lateral position adjustment, with the sleeve's lateral movement guided and limited for stable movement and to prevent rotation. One end is fitted with an adjustable tilt head. By introducing lateral length adjustment and tilt angle adjustment functions, each driver can "tailor-make" the lever's position and angle according to their body type, driving habits, and comfort preferences, achieving optimal human-machine interaction. This eliminates operational pressure caused by difficulty in reaching the lever or awkward angles, keeping the wrist and arm in a naturally relaxed state. Even during long drives or frequent operation in inclement weather, the driver feels relaxed. Easy and accurate operation reduces cognitive and physical burdens, allowing the driver to focus more on road conditions.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] Please see Figure 1-6 As shown, this embodiment is a wiper control lever based on the type of dirt, including:

[0042] The lever structure 100 includes a connecting lever 106, a sleeve 101 sleeved on the outside of the connecting lever 106, an operating head 102 located on one side of the sleeve 101, side blocks 105 symmetrically distributed at one end of the operating head 102, and a central retaining sleeve 107 located at one end of the sleeve 101 and inside the side block 105.

[0043] Adjustment structure 200 includes a mounting groove 201 inside the upper end of sleeve 101, a rotating shaft 211 rotatably mounted inside the mounting groove 201, a gear 212 sleeved on the outside of the rotating shaft 211, a toothed plate 205 and a toothed plate 214 located on both sides of the mounting groove 201 and meshing with the gear 212, a support ring 207 located at the lower end of the toothed plate 205, a spring 210 located between the support ring 207 and the lower end of the mounting groove 201, a pressure rod 204 located at the upper end of the toothed plate 205, a pressure block 203 located at the upper end of the pressure rod 204 and sleeved on the outside of sleeve 101, a slot 202 equally distributed on the upper end of the connecting lever 106, and a locking block 215 located at the lower end of the toothed plate 214 and locked inside the slot 202.

[0044] The connecting lever 106 has grooves 109 at both ends, and the sleeve 101 has balls 108 rotatably mounted on the outer walls at both ends that roll and fit against the inner walls of the grooves 109.

[0045] Guide rails 213 are provided on both inner walls of the mounting groove 201, and sliders 206 that are slidably installed on the outer wall of the guide rails 213 are provided at opposite ends of toothed plate 1 205 and toothed plate 214.

[0046] The outer wall of the operating head 102 is fitted with a latex sleeve 103, and the outer wall of the latex sleeve 103 is provided with anti-slip texture 104.

[0047] The lower end of the support ring 207 is provided with a positioning rod 208 located inside the spring 210, and the lower inner wall of the mounting groove 201 is provided with a positioning cylinder 209 sleeved on the outer wall of the positioning rod 208 and located inside the spring 210.

[0048] as well as;

[0049] Adjustment structure 2 300 includes a mounting shaft 306 rotatably mounted inside the central sleeve 107 and connected to the side blocks 105 at both ends; a slot 2 308 with a ring array distributed on the outer wall of the mounting shaft 306; a stroke groove 305 opened inside the upper end of the central sleeve 107; a pressure rod 2 303 slidably mounted inside the stroke groove 305; and a locking block 2 307 located at the lower end of the pressure rod 2 303 and inserted into the slot 2 308.

[0050] A support ring 302 is sleeved on the outer wall of the upper end of the pressure rod 303. A spring 304 is sleeved on the outside of the pressure rod 303 between the support ring 302 and the central retaining sleeve 107. A pull rod 301 is provided at the upper end of the pressure rod 303.

[0051] Use adjustment structure 1 200 and adjustment structure 2 300;

[0052] Press down on the pressure block 203 on the outside of the sleeve 101 with your finger. At this time, the pressure block 203 pushes the pressure rod 204 below, forcing the toothed plate 205 to compress the spring 210 and move downward. At the same time, the gear 212 meshing with the toothed plate 205 drives the toothed plate 214 on the symmetrical side to move upward, so that the locking block 215 at the bottom of the toothed plate 214 disengages from the slot 202 on the connecting lever 106. At this time, the sleeve 101 (including the operating head 102) can slide freely to a comfortable length (the sleeve 101 moves smoothly in the groove 109 of the connecting lever 106 through the ball bearing 108). After releasing the pressure block 203, the spring 210 rebounds and pushes the toothed plate 214 to reset. The locking block 215 automatically engages with the nearest slot 202 to complete the locking.

[0053] Pulling the lever 301 at the top of the operating head 102 upwards causes the pressure lever 303 to rise and stretch the spring 304, disengaging the locking block 307 at the bottom of the pressure lever 303 from the slot 308 on the mounting shaft 306. At this point, the operating head 102 can be freely rotated to a position that matches the natural angle of the wrist. The mounting shaft 306 rotates within the central sleeve 107. After releasing the lever 301, the spring 304 returns to its original position, pushing the locking block 307 into the annular slot 308, thus achieving multi-position tilt angle fixation, in 15° increments.

[0054] Mechanical extension and retraction are achieved through the linkage mechanism of gear 212 with toothed plate 205 and toothed plate 214. Gear 212 meshes with toothed plate 205 and toothed plate 214 to form a reverse motion pair, ensuring that the two toothed plates are simultaneously unlocked when pressed down and automatically engaged and locked when released. The structure is compact and the operation can be controlled with one hand. Based on the pin positioning of spring 204 and locking block 207, the insertion design of locking block 207 and annular slot 208 provides reliable gear holding force. The mounting shaft 306 bears the shifting torque under the support of side block 105 to avoid play.

[0055] Traditional fixed levers cannot be adapted to different driver body sizes. For example, shorter drivers need to lean forward to reach the lever, while taller drivers need to bend their arms to operate it. This leads to distorted movements and delayed responses when shifting gears in an emergency, such as when switching to HI gear in a sudden downpour.

[0056] It is worth noting that, because the wiper is designed for dirty conditions, the connecting lever 106 is similar to the traditional structure. The lever integrates multiple sets of circuit contacts, with different contact combinations corresponding to different gear positions. When the driver moves the lever to a specific gear position (such as INT / LO / HI), the contacts connect to the corresponding circuit, sending an electrical signal to the Body Control Module (BCM) or the wiper motor control module. The module controls the speed (low / high speed) or starts / stops the wiper motor according to the signal command. The lever usually integrates an interval time adjustment knob, which adjusts the signal frequency through a variable resistor to control the interval duration of the wiper wiping. When the lever is pulled towards the driver, the water pump circuit is triggered, starting the windshield washer fluid spray and simultaneously activating the wiper motor to automatically wipe several times to ensure water stains are removed. Pushing the lever to the instantaneous position triggers a single wiping cycle, and releasing it resets the position.

[0057] The installation and fixing process of the lever is as follows: disconnect the vehicle power to prevent short circuit, remove the cover under the steering wheel (usually fixed by clips or screws), loosen the steering column trim cover to expose the lever base, which is fastened to the steering column bracket by metal clamps or bolts, and connect the multi-pin wiring harness plug at the end of the lever to transmit control signals. Insert the lever into the reserved hole in the steering column, align the fixing hole, tighten the base bolts / clamps to ensure no shaking, and firmly insert the wiring harness plug (foolproof design to prevent misinsertion). Reset the cover and test the function, including the response of each gear and the linkage of the water spray.

[0058] With the lateral driven box tilt adjustment control head 102, each driver can achieve optimal human-machine interaction by using the lever according to their own body type, driving habits, and comfort preferences, eliminating the operational pressure caused by not being able to reach the lever or the angle being awkward. The wrist and arm remain in a natural and relaxed state, making it easier to operate even on long journeys or in inclement weather. Easy and accurate operation reduces the driver's cognitive load and physical burden, allowing them to focus more on road conditions. Especially in critical situations such as sudden weather changes, quick and accurate adjustment of the wipers is crucial for safety. The adjustable design reflects attention to user experience details and ergonomics, enhancing the vehicle's interior quality and user satisfaction.
