Description
Technical Field
[0001] This utility model relates to the field of automotive windshield wiper technology, specifically a heated automotive windshield wiper. Background Technology
[0002] In the field of automotive windshield wipers, traditional wipers have many problems when facing cold weather and the need to replace wiper blades, which adversely affects the driver's driving safety and ease of use.
[0003] In cold climates, especially in winter, car windshields are prone to accumulating snow and ice. Traditional windshield wipers do not have a heating function, and when ice forms between the wipers and the windshield, the wipers cannot work properly. Forcing the wipers on can not only damage the wipers themselves but also fail to effectively remove the snow and ice from the windshield, obstructing the driver's vision. In some northern regions, winter outdoor temperatures are often too low, and after a car has been parked overnight, a thick layer of ice can form on the windshield, which traditional wipers cannot clear. The driver must manually remove the ice. If the snow and ice on the windshield are not removed in time, it will seriously affect the driver's vision and increase the risk of traffic accidents.
[0004] For example, in a car windshield wiper with announcement number CN117429388A, a connecting rod is fixedly installed on the upper end of the wiper blade, and a swing arm is fixedly installed on the end of the connecting rod away from the wiper blade. A swing rod is hinged to one end of the swing arm, and a return spring is provided between the swing arm and the swing rod. An output shaft that drives the swing rod to rotate is fixedly connected to the end of the swing rod away from the swing arm, so as to realize the separation and contact between the wiper blade and the windshield, and reduce the production cost.
[0005] For example, a new type of car windshield wiper with announcement number CN221698670U has a wiper blade that can be detachably contacted with the car windshield on the other side. A guide groove is provided at the outer edge of the windshield, and a slider is provided at one end of the sliding arm, sliding within the guide groove. One end of the swing arm is connected to a drive motor, which more thoroughly cleans dirt from the four corners of the windshield, resulting in better wiper performance. However, this type of wiper lacks a heating function, making it prone to icing in cold weather and unable to properly remove snow and ice, severely affecting driving visibility. Other problems exist, such as the fact that replacing traditional car wiper blades is usually complex, requiring specialized tools and certain operating skills, making it difficult for ordinary drivers to complete the replacement themselves. Replacing wiper blades on some models requires disassembling multiple parts, which is difficult for drivers unfamiliar with the car's structure. Some models may require replacing the entire wiper assembly to replace wiper blades, increasing replacement costs and also posing a threat to driving safety. Utility Model Content
[0006] The purpose of this utility model is to provide a heated car windshield wiper to solve the problems mentioned in the background art, such as windshield wipers without heating function, which are prone to freezing in cold weather and cannot properly remove snow and ice, seriously affecting driving visibility, and windshield wiper blade replacement being complicated, requiring professional tools and skills, often requiring the entire wiper assembly to be replaced, which is costly and difficult for drivers to replace themselves.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a heatable car windshield wiper, including a wiper motor and a wiper arm fixedly installed at the output end of the wiper motor; a connecting housing is rotatably installed on the upper end of the wiper arm, and a heat-conducting plate is fixedly installed in the middle of the inner part of the connecting housing, and the heat-conducting plate is made of heat-conducting copper sheet; a heating mechanism is provided inside the connecting housing, and a heater is fixedly installed in the middle of the left end of the heat-conducting plate; a wiper blade is installed inside the right end of the connecting housing, and the left end of the wiper blade is installed on the right end of the heat-conducting plate; a placement groove is opened on the upper end of the wiper blade, and two placement grooves are evenly distributed with the connecting housing as the symmetrical center; a mechanism for easy disassembly is provided on the wiper blade, and a first spring is installed in the lower end of the placement groove.
[0008] Furthermore, the heating mechanism includes a heat pipe that is installed through the upper end of the heater, and the heat pipe is U-shaped. The heat pipe is installed above the left end of the heat-conducting plate, and two heat-conducting plates are evenly distributed with the connecting shell as the center of symmetry. A control chip is fixedly installed in the middle of the connecting shell.
[0009] Furthermore, a temperature sensor is installed at the lower end of the control chip and is connected to the control chip. A relay is installed at the upper end of the control chip and is connected to the control chip and the relay is connected to the heater.
[0010] Furthermore, the easy-to-disassemble mechanism includes a buckle mounted on the upper end of the first spring, and a buckle nested inside the upper end of the placement groove.
[0011] Furthermore, the upper end of the connecting shell is provided with a slot, and two slots are evenly distributed with the connecting shell as the center of symmetry, and the buckle and the slot cooperate with each other.
[0012] Furthermore, a push plate is slidably installed inside the slot, and a second spring is installed on the left end of the push plate. Two second springs are evenly distributed with the connecting shell as the center of symmetry, and the upper end of the second spring is installed inside the upper end of the slot.
[0013] Furthermore, a guide block is fixedly installed on the upper left side of the wiper blade, and four guide blocks are evenly distributed with the connecting shell as the center of symmetry. A guide groove is opened on the upper left side inside the connecting shell, and the guide groove cooperates with the guide block.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The wiper blades on the outer casing wipe the windshield. The temperature sensor monitors the temperature of the wipers and the outside environment in real time and feeds the temperature information back to the control chip. This causes the control relay to close, and the heat is quickly transferred to various parts of the heat-conducting plate through the heat pipe. The heat-conducting plate directly heats the contact area between the wiper blades and the windshield, quickly melting the ice between them, effectively removing snow and ice, improving driving safety, and adapting to different low-temperature environments.
[0016] Furthermore, the heating function can be activated promptly in low-temperature environments to quickly melt the ice between the wipers and the windshield, ensuring that the wipers can wipe normally. Whether in the harsh winter of the north or in environments where the temperature drops sharply, the wipers can always maintain good working condition, avoid damage to the wipers due to icing, and extend the service life of the wipers.
[0017] Furthermore, it effectively removes snow and ice from the windshield, providing the driver with a clear view. In adverse weather conditions, the driver can clearly observe road conditions and react in time, greatly reducing the risk of traffic accidents caused by obstructed vision. It can automatically adjust the heating state according to the actual temperature to avoid overheating, enabling the wipers to work efficiently in different low-temperature environments and enhancing the wipers' adaptability to various cold weather conditions.
[0018] 2. When it is necessary to replace the wiper blade, the operator presses the push plate inward, causing the push plate to move inward. Then, the second spring begins to stretch, and the push plate pushes the clip inward. The clip then moves out of the slot and releases the engagement. The guide block on the wiper blade engages with the guide groove inside the connecting housing to limit the movement. This simple and quick replacement method allows the driver to operate the device themselves, improving ease of use and ensuring driving safety.
[0019] Furthermore, replacing the wiper blades is as simple as the driver pressing the push plate to easily remove and install them. Compared to traditional replacement methods, this saves a lot of time. Only the wiper blades need to be replaced, without replacing the entire wiper assembly, reducing replacement costs. Whenever the wiper blades need to be replaced, the operation can be carried out immediately, improving the convenience and autonomy of car use and allowing drivers to better maintain their vehicles.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1: Please refer to Figures 1-7This utility model provides the following technical solution: a heatable car windshield wiper, including a wiper motor 1 and a wiper arm 2 fixedly installed at the output end of the wiper motor 1; a connecting housing 3 is rotatably installed on the upper end of the wiper arm 2, and a heat-conducting plate 4 is fixedly installed in the middle of the connecting housing 3, and the heat-conducting plate 4 is made of heat-conducting copper sheet; a heating mechanism is provided inside the connecting housing 3, and a heater 5 is fixedly installed in the middle of the left end of the heat-conducting plate 4; a wiper blade 6 is installed inside the right end of the connecting housing 3, and the left end of the wiper blade 6 is installed on the right end of the heat-conducting plate 4; a placement groove 7 is opened on the upper end of the wiper blade 6, and two placement grooves 7 are evenly distributed with the connecting housing 3 as the symmetrical center; the wiper blade 6... The upper part is equipped with a disassembly mechanism, and a first spring 8 is installed at the lower end of the placement slot 7. The heating mechanism includes a heater 5 with a heat pipe 9 installed through the upper end. The heat pipe 9 is "U" shaped and is installed above the left end of the heat-conducting plate 4. Two heat-conducting plates 4 are evenly distributed with the connecting shell 3 as the center of symmetry. A control chip 10 is fixedly installed in the middle of the connecting shell 3. A temperature sensor 11 is installed at the lower end of the control chip 10 and is connected to the control chip 10. A relay 12 is installed at the upper end of the control chip 10 and is connected to the control chip 10 and the heater 5.
[0030] The wiper motor 1 drives the wiper arm 2 to rotate, which in turn drives the connecting housing 3 to rotate reciprocally. The wiper blade 6 on the connecting housing 3 wipes the windshield. Simultaneously, the temperature sensor 11 monitors the temperature of the wiper and the outside environment in real time and feeds the temperature information back to the control chip 10. The control chip 10 has preset low-temperature and high-temperature thresholds. When the temperature sensor 11 detects that the temperature of the wiper and the outside environment is lower than the low-temperature threshold, the control chip 10 determines that heating is required. Therefore, it controls the relay 12 to close, turning on the heater 5 to start working. The heat is quickly transferred to various parts of the heat-conducting plate 4 through the heat pipe 9. The heat-conducting plate 4 directly heats the contact area between the wiper blade 6 and the windshield, quickly melting the ice between them, allowing the wiper blade 6 to move freely and wipe the windshield normally. When the temperature sensor 11 detects that the temperature of the wiper and the outside environment is higher than the high-temperature threshold, the control chip 10 controls the relay 12 to open, and the heater 5 stops heating, thus avoiding overheating.
[0031] Example 2: Based on Example 1, a disassembly-friendly mechanism is also disclosed, the specific structure of which is as follows:
[0032] The easy-to-disassemble mechanism includes a buckle 13 installed on the upper end of the first spring 8, and a buckle 13 nested inside the upper end of the placement groove 7. A slot 14 is opened on the upper end of the connecting shell 3, and two slots 14 are evenly distributed with the connecting shell 3 as the center of symmetry. The buckle 13 and the slot 14 cooperate with each other. A push plate 15 is slidably installed inside the slot 14, and a second spring 16 is installed on the left end of the push plate 15. Two second springs 16 are evenly distributed with the connecting shell 3 as the center of symmetry. The upper end of the second spring 16 is installed inside the upper end of the slot 14. A guide block 17 is fixedly installed on the left side of the upper end of the wiper blade 6, and four guide blocks 17 are evenly distributed with the connecting shell 3 as the center of symmetry. A guide groove 18 is opened on the left side of the upper end of the connecting shell 3, and the guide groove 18 cooperates with the guide block 17.
[0033] When the wiper blade 6 needs to be replaced, the worker presses the push plate 15 inward, causing the push plate 15 to move inward. Then, the second spring 16 begins to stretch, and the push plate 15 pushes the buckle 13 inward. The buckle 13 then moves into the placement groove 7, while the first spring 8 begins to compress. The buckle 13 then moves out of the groove 14 and is released from the locking state. The guide block 17 on the wiper blade 6 cooperates with the guide groove 18 inside the connecting housing 3 to limit the movement. Then, the upper and lower sides of the wiper blade 6 are pressed, and the buckle 13 and the inside of the connecting housing 3 cooperate to compress the first spring 8. When the buckle 13 moves to the groove 14, the first spring 8 pushes the buckle 13 into the groove 14, thus fixing the wiper blade 6 inside the connecting housing 3.
