As an important component of the vehicle, the automobile wiper system effectively scrapes off the rain, snow and dust on the front windshield of the car in rainy and snowy weather, which can ensure that the driver has a good field of vision. The wiper motor is the driving output component of the wiper system. The high-speed gear in the wiper motor is a large current input and high-speed output, and the low-speed gear is a small current input and low-speed output. In the existing wiper, the wiper motor switch is connected through different contacts to realize the gear conversion of the wiper motor, which can adapt to weather conditions with different rain and snow intensities.

When the wiper motor switch knob stops at a certain gear position, the circuit contact is connected, and the wiper motor starts to operate according to the corresponding function. However, during the operation of the wiper motor switch, when the wiper motor switch passes through the low-speed gear from the closed state and directly enters the high-speed gear, or directly passes through the low-speed gear from the high-speed gear to the closed state, the passing gear cannot start the corresponding function due to the short connection time. The wiper motor directly runs at a high load, and the current in the wiper motor changes dramatically, resulting in severe transient surge pulses in the electronic and electrical system of the entire vehicle, which may impact and damage the electronic and electrical equipment of the entire vehicle.

[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0031] The current wiper motor switches have knob type and lever type in terms of external structure, and the gears are OFF-INT-LOW-HIG, respectively. OFF is the stop gear; INT is the intermittent gear, in which the wiper motor works intermittently; LOW is the low-speed gear; HIG is the high-speed gear. In the prior art, each gear uses a point contact switch. When the switch is rotated to the corresponding gear, the wiper switch contacts are connected, and the wiper motor is controlled to operate according to the corresponding working conditions. In the low-speed gear, the wiper motor runs at a low speed, and in the high-speed gear, the wiper motor runs at a high speed. When the user operates the wiper motor switch knob, the switch can be directly from OFF to HIG or from HIG to OFF. Since INT and LOW are point contacts, during the wiper motor switch operation, the switch knob is directly rotated from OFF to HIG or from HIG to OFF. The passing gear cannot start the corresponding function due to the short on-time. The wiper motor runs directly at high load, and the INT and LOW gears will be directly skipped when switching gears. For example, the HIG gear will be directly entered from OFF. At this time, the wiper motor will run directly at high speed, and the current in the wiper motor circuit will change sharply. Since the wiper motor is an inductive load, the internal inductance generates an induced electromotive force that hinders the current change. The faster the current changes, the greater the induced electromotive force. The induced voltage is transmitted into the vehicle's electronic and electrical system, forming a transient surge pulse. The transient surge voltage caused by the large current change inside the motor will have a serious impact on the vehicle's electrical system, seriously affecting the normal operation of automotive electronic and electrical components and worsening the vehicle's electronic and electrical working environment.

[0032] Based on the above, the utility model proposes a wiper, which sets a continuously extending wire trigger area between the contact of the intermittent gear position and the contact of the high-speed gear position to ensure that the wiper motor switch can have a certain period of resident contact in the wire trigger area of ​​the low-speed gear position, so that the internal current of the wiper motor gradually changes, reducing the current change rate, which can effectively reduce the impact of transient surge voltage and improve the safety of the vehicle's electronic and electrical equipment. Figure 1-Figure 3 A wiper according to an embodiment of the utility model is described.

[0033] like Figure 1 , which is a block diagram of a wiper according to an embodiment of the utility model, wherein the wiper 10 comprises a wiper motor 1 and a wiper adjuster 2. The wiper motor 1 has a power connection part.

[0034] The wiper regulator 2 has a control position 21 for controlling the operation of the wiper motor 1 on the adjustment path. Specifically, the wiper regulator 2 is a wiper motor switch. The common wiper motor switch 10 includes a control handle or a control knob, a position positioning mechanism, a follower contact, a static contact, and an external protection and circuit connection device. The electrical connection of the power connection part of the wiper motor 1 is suitable for being electrically connected to the contact of one of the control positions 21.

[0035] The control gear 21 includes a stop gear point OFF, an intermittent gear point INT, a high-speed gear point HIG, and a low-speed gear area LOW. The stop gear point OFF is located on one side of the adjustment path of the wiper regulator 2; the intermittent gear point INT is adjacent to the stop gear point OFF on the adjustment path of the wiper regulator 2; the high-speed gear point HIG is located on the other side of the adjustment path of the wiper regulator 2; and the low-speed gear area LOW is located between the high-speed gear point HIG and the intermittent gear point INT on the adjustment path of the wiper regulator 2. The stop gear point OFF, the intermittent gear point INT, the high-speed gear point HIG, and the low-speed gear area LOW in the figure are only for illustration and are not used as a limitation on the form and control method of the gear.

[0036] It can be understood that the stop gear position OFF, the intermittent gear position INT, the low-speed gear area LOW and the high-speed gear position HIG are arranged in sequence. Among them, the explanation is based on the currently commonly used automobile knob wiper motor switch. The initial position of the wiper adjuster 2 is the stop gear position OFF, and the stop gear position OFF is connected to the power connection part of the wiper motor 1, and the wiper motor 1 is turned off at this time; when the wiper adjuster 2 rotates a certain angle, such as 30°, it enters the intermittent gear position INT, and the intermittent gear position INT is connected to the power connection part of the wiper motor 1, and the wiper motor 1 works intermittently; the wiper adjuster 2 continues to rotate a certain angle and enters the low-speed gear area LOW, at which time the low-speed gear area LOW is connected to the power connection part of the wiper motor 1, and the wiper motor 1 is controlled to run continuously at a low speed; after the wiper adjuster 2 continues to rotate a certain angle, it enters the high-speed gear position HIG, and the high-speed gear position HIG is connected to the power connection part of the wiper motor 1, and the wiper motor 1 runs continuously at a high speed. Generally speaking, the control methods of the wiper motor system are different. The corresponding functional circuits are connected, and the wiper motor 1 is directly driven to operate, or a signal is sent to the body controller, and the body controller drives the wiper motor 1 to operate. No specific limitation is made here.

[0037] In the embodiment, the low-speed gear zone LOW is set to extend continuously on the rotation path of the wiper regulator 2, and the contact structure of the low-speed gear zone LOW has a wire trigger zone, which extends continuously and is located between the contact of the intermittent gear point INT and the contact of the high-speed gear point HIG. In other words, the contact structure of the low-speed gear of the wiper motor switch, i.e., the wiper regulator 2, is improved, and the point contact form used in the low-speed gear zone LOW in the prior art is changed to a line contact form. When the wiper regulator 2 directly changes from OFF to HIG gear or from HIG to OFF, it is guaranteed to have a certain time of contact when passing through the LOW gear, thereby ensuring that the wiper motor 1 first enters the low gear mode and then transitions to the high gear mode or is turned off, so that the working current of the wiper motor 1 gradually increases or decreases, reducing the amplitude of the transient surge pulse and reducing the transient impact on the electronic and electrical system of the whole vehicle.

[0038] In order to extend the time for the wiper adjuster 2 to pass through the low-speed gear zone LOW, the low-speed gear rotation stroke of the wiper adjuster 2 is increased, that is, the adjustment path of the wiper adjuster 2 when passing through the low-speed gear zone LOW is increased. By adopting the method of increasing the low-speed gear stroke, for example, for a knob-type wiper motor switch, the design of increasing the stroke from INT to LOW and from LOW to HIG can be achieved by increasing the rotation angle between the INT gear and the LOW gear, and the LOW gear and the HIG gear. By adopting this unequal switch stroke design, when the wiper adjuster 2 passes through the low-speed gear zone LOW, the low-speed gear residence time can be effectively extended, and the current change rate of the wiper motor 1 can be reduced.

[0039] According to the wiper 10 proposed in the embodiment of the utility model, by setting a continuously extending line trigger area between the contact of the intermittent gear point INT and the contact of the high-speed gear point HIG, during the operation of the wiper motor 1 switch, when the wiper adjuster 2 is directly controlled from the stop gear point OFF to the high-speed gear point HIG, the wiper motor 1 will first enter the low-speed mode and then enter the high-speed mode; or, when the wiper adjuster 2 is directly controlled from the high-speed gear point HIG to the stop gear point OFF, the wiper motor 1 will first enter the low-speed mode from the high-speed mode and then be turned off, ensuring that the wiper motor 1 switch can have a certain period of resident contact in the line trigger area of ​​the low-speed gear, so that the internal current of the wiper motor 1 changes gradually. By reducing the current change rate, the impact of transient surge voltage can be effectively reduced, thereby improving the safety of the vehicle's electronic and electrical equipment.

[0040] In some embodiments of the present invention, Figure 2 As shown, it is a schematic diagram of a knob-type wiper adjuster according to an embodiment of the utility model, wherein the wiper adjuster 2 is an adjustment knob, and the stop gear position OFF, the intermittent gear position INT, the low-speed gear area LOW and the high-speed gear position HIG are arranged in sequence along the circumference of the adjustment knob.

[0041] The adjusting knob is configured as a cam structure, and the cam structure includes: a first convex portion, a second convex portion, a third convex portion, and a fourth convex portion arranged in sequence along the circumferential direction, the stop gear point OFF is formed on the first convex portion, the intermittent gear point INT is formed on the second convex portion, the low-speed gear area LOW is formed on the third convex portion, and the high-speed gear point HIG is formed on the fourth convex portion. The stop gear point OFF, the intermittent gear point INT, and the high-speed gear point HIG corresponding to the first convex portion, the second convex portion, and the fourth convex portion, respectively, may all be point contacts, the low-speed gear area LOW corresponding to the third convex portion is a line contact, and the third convex portion is a continuously extended line trigger area.

[0042] For the knob-type wiper adjuster 2, on the basis of changing the contact mode of the low-speed gear zone LOW from a point contact to a line contact, it is also possible to further set the angle between the stop gear point OFF and the intermittent gear point INT on the circumference of the adjustment knob to be smaller than the angle between the intermittent gear point INT and the midpoint of the low-speed gear zone LOW, and smaller than the angle between the midpoint of the low-speed gear zone LOW and the high-speed gear point HIG. Specifically, Figure 2 As shown, the angle between the stop gear point OFF and the intermittent gear point INT can be set to 25°~35°, preferably 30°, the angle from the intermittent gear point INT to the midpoint of the low-speed gear area LOW can be set to 40°~50°, preferably 45°, and the angle from the midpoint of the low-speed gear area LOW to the high-speed unit point can be set to 40°~50°, preferably 45°.

[0043] For the knob-type wiper adjuster 2, the rotation angle between the intermittent gear point INT and the low-speed gear area LOW, and the rotation angle between the low-speed gear area LOW and the high-speed gear point HIG are increased by 10° to 20° compared to the rotation angle between the stop gear point OFF and the intermittent gear point INT, so as to realize the design of increasing the stroke from INT to LOW and from LOW to HIG. By adopting this design of unequal switch stroke, during the process of switching across the low-speed gear, when the wiper adjuster 2 passes through the low-speed gear area LOW, the residence time of the low-speed gear can be effectively extended, and the sharp change of the current in the wiper motor 1 and the resulting transient impact are effectively reduced, thereby improving the electronic and electrical working environment of the whole vehicle and preventing the occurrence of switch and relay contact ablation.

[0044] In other embodiments of the present invention, Figure 3 The figure shows a schematic diagram of a lever-type wiper regulator according to an embodiment of the utility model, wherein the wiper regulator 2 is an adjustment lever, and the stop gear position OFF, the intermittent gear position INT, the low-speed gear area LOW and the high-speed gear position HIG are arranged in sequence along the swing direction of the adjustment lever. The adjustment lever is equivalent to a moving contact, and the stop gear position OFF, the intermittent gear position INT, the low-speed gear area LOW and the high-speed gear position HIG are equivalent to static contacts. In addition, a common terminal P is also provided in the contact area of ​​the contact point. When the adjustment lever contacts the stop gear position OFF, the intermittent gear position INT, the low-speed gear area LOW and the high-speed gear position HIG respectively, they all contact the common terminal at the same time, thereby forming a closed loop, and the wiper motor 1 performs corresponding operations.

[0045] In some embodiments, Figure 3As shown, for the lever-type wiper regulator 2, on the basis of changing the contact mode of the low-speed gear zone LOW from a point contact to a line contact, the angle between the stop gear point OFF and the intermittent gear point INT can be further set to be smaller than the angle between the intermittent gear point INT and the midpoint of the low-speed gear zone LOW, and smaller than the angle between the midpoint of the low-speed gear zone LOW and the high-speed gear point HIG in the swing direction of the adjustment lever. Specifically, Figure 3 As shown, the angle between the stop gear point OFF and the intermittent gear point INT can be set to 10°~20°, preferably 15°, the angle from the intermittent gear point INT to the midpoint of the low-speed gear area LOW is 15°~25°, preferably 20°, and the angle from the midpoint of the low-speed gear area LOW to the high-speed unit point is 15°~25°, preferably 20°.

[0046] Based on the above, for the lever-type wiper adjuster 2, the rotation angle between the intermittent gear point INT and the low-speed gear area LOW, and the rotation angle between the low-speed gear area LOW and the high-speed gear point HIG are increased by 10° to 20° compared to the rotation angle between the stop gear point OFF and the intermittent gear point INT, so as to realize the design of increasing the stroke from INT to LOW and from LOW to HIG. By adopting this design of unequal switch stroke, during the low-speed gear switching process, when the wiper adjuster 2 passes through the low-speed gear area LOW, the residence time of the low-speed gear can be effectively extended, and the sharp change of the current in the wiper motor 1 and the resulting transient impact are effectively reduced, thereby improving the electronic and electrical working environment of the whole vehicle and preventing the occurrence of switch and relay contact ablation.

[0047] In some embodiments of the utility model, on the adjustment path of the wiper adjuster 2, a damping mechanism is constructed between the intermittent gear point INT and the low-speed gear area LOW, and between the low-speed gear area LOW and the high-speed gear area. The damping mechanism allows the wiper adjuster 2 to leave the low-speed gear area LOW when the adjustment torque of the wiper adjuster 2 reaches a preset torque.

[0048] It can be understood that by constructing a damping mechanism between the intermittent gear point INT and the low-speed gear area LOW, and between the low-speed gear area LOW and the high-speed gear area, the torque for switching from the low-speed gear area LOW to other gears can be appropriately increased. In this way, when passing through the low-speed gear area LOW, the switch can be prevented from quickly passing through the gear, thereby increasing the residence time of the wiper adjuster 2 in the low-speed gear area LOW, effectively reducing the sharp change of current in the wiper motor 1 and the resulting transient impact, improving the electronic and electrical working environment of the entire vehicle, and preventing the occurrence of switch and relay contact burning.

[0049] Based on the above, in order to prolong the time for the wiper adjuster 2 to pass through the low-speed gear area LOW, the wiper 10 of the embodiment of the utility model adopts a method of increasing the low-speed gear stroke, and changes the contact mode of the low-speed gear area LOW from a point contact to a line contact, and further increases the rotation angle between the INT gear and the LOW gear and between the LOW gear and the HIG gear, and appropriately increases the torque for switching from the low-speed gear area LOW to other gears, so that the wiper adjuster 2 can increase the residence time of 0.5-1s in the low-speed gear area LOW during the low-speed gear switching process, and effectively reduce the transient surge voltage value by gradually reducing the change rate of the wiper motor working current, thereby optimizing the vehicle electronic and electrical use environment, effectively reducing the failure rate of electronic and electrical equipment, and ensuring the safe operation of vehicle electronic and electrical equipment.

[0050] In some embodiments of the present invention, a vehicle is also provided, such as Figure 4 , which is a block diagram of a vehicle according to an embodiment of the present utility model, wherein the vehicle 100 includes a wiper 10 according to any one of the above embodiments.

[0051] According to the vehicle 100 proposed in the embodiment of the utility model, by setting the wiper 10 proposed in the embodiment of the first aspect, the contact mode of the low-speed gear area LOW is changed from a point contact to a line contact, thereby increasing the stroke of the low-speed gear, so that the wiper adjuster 2 can effectively prolong the time for passing through the low-speed gear area LOW during the low-speed gear conversion process, thereby gradually reducing the change rate of the wiper motor working current, effectively reducing the transient surge voltage value, optimizing the electronic and electrical use environment of the vehicle 100, and effectively reducing the failure rate of electronic and electrical equipment, thereby ensuring the safe operation of the electronic and electrical equipment of the vehicle 100.
