[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] The embodiment of the present application provides a self-cleaning antibacterial door handle, which can solve the problem that some people forget to actively spray alcohol for disinfection due to different personal habits.

[0039] See also Figures 1 to 5 As shown, the embodiment of the present application provides a self-cleaning antibacterial door handle, including a support handle 1, a rotating handle 2, a drive assembly and a cleaning assembly 3, wherein two support handles 1 are provided, and are installed on the door panel by using connectors including but not limited to screws, and the support handle 1 can be made of high-strength, corrosion-resistant materials (such as stainless steel or aluminum alloy) to ensure stability and durability under long-term use. Lightweighting should also be considered during design to reduce the additional burden on the door panel; the rotating handle 2 is connected between the two support handles 1 and is rotatably connected to the two support handles 1 respectively, so that the door handle is formed by the rotating handle 2 and the two support handles 1, wherein the two support handles 1 are used as fixed parts, and the rotating handle 2 is used as a part that directly contacts the occupants, so the rotating handle 2 is made of antibacterial material to effectively inhibit bacterial growth. The shape design should be ergonomic to ensure comfortable grip and easy operation. In addition, the surface of the rotating handle 2 is also designed to be a slightly convex texture, which increases friction and facilitates cleaning. The driving assembly is further connected between the two support handles 1 and the rotating handle 2, and the driving assembly is used to drive the rotating handle 2 to rotate around the two support handles 1; the cleaning assembly 3 is installed on the door panel, and the cleaning assembly 3 is used to clean the rotating handle 2.

[0040] During use, before the passenger touches the rotating handle 2, that is, when the passenger unlocks the vehicle from a distance or before the passenger pulls the handle inside, the rotating handle 2 is driven to rotate by the driving component, and then the cleaning component 3 effectively cleans the rotating handle 2, and the cleaning range is comprehensive. In this application, the driving component is connected to the vehicle's center console signal, and a controller is provided on the center console, and the controller is connected to the cleaning component 3 signal. During specific operation, the driving component is controlled to run through signal transmission, and the cleaning component 3 is started by pressing the switch button of the controller. During the rotation of the rotating handle 2, the cleaning component 3 comprehensively cleans all parts of the rotating handle 2. It is easy to operate and has a wide range of general uses. It can achieve rapid disinfection before passengers get on and off the vehicle, reducing the situation where passengers operate on their own, and can be uniformly controlled by the driver.

[0041] In the present application, the cleaning assembly 3 includes an ultraviolet light strip 30 and a circuit board 31. First, a bracket is provided on the door panel. The ultraviolet light strip 30 is mounted on the bracket by a structure such as a buckle. The wiring harness on the ultraviolet light strip 30 can also be connected to the bracket. The bracket can be made of a light but strong material (such as aluminum alloy) and is firmly fixed to the door panel by bolts or buckles. In addition, the light source of the ultraviolet light strip 30 faces the rotating handle 2, so the shape and position of the bracket should ensure that the ultraviolet light strip 30 can fit tightly and the light source can evenly irradiate the surface of the rotating handle 2. The circuit board 31 is installed on the door panel and connected to the ultraviolet light strip 30, thereby effectively providing power for the ultraviolet light strip 30. The ultraviolet light strip 30, commonly known as the UV ultraviolet light strip, is a lighting device that can emit special ultraviolet light. The core principle of the ultraviolet light strip 30 is to use ultraviolet light of a specific wavelength to activate chemical reactions, thereby achieving functions such as curing, sterilization or detection.

[0042] Before it is officially put into use, it is necessary to simulate the turning handle 2 and turning the ultraviolet light strip 30 for one circle to see how the sterilization situation of the irradiated part is; how long does it take to completely kill the bacteria. If the time is longer, it is necessary to redesign the installation position voltage and width of the ultraviolet light strip 30 according to the sterilization situation. Ensure that when the handle 2 starts to rotate, the ultraviolet light emitted by the ultraviolet light strip 30 disinfects the rotating life, the ultraviolet disinfection effect is good, the overall installation is convenient, and the structure is reliable.

[0043] In the present application, in order to prevent the ultraviolet light strip 30 from being exposed to the outside and eroded by rain or dust, the ultraviolet light strip 30 is deliberately installed on the inner side of the door panel, and then a light-transmitting plate 32 is provided on the door panel between the rotating handle 2 and the ultraviolet light strip 30. After the ultraviolet light strip 30 is installed on the inner side of the door panel, it can well protect the ultraviolet light strip 30, and under the action of the light-transmitting plate 32, it is ensured that the ultraviolet light strip 30 normally emits light to disinfect the rotating handle 2, and the light-transmitting plate 32 further protects the ultraviolet light strip 30, and also ensures the integrity of the structure on the door panel. It effectively prevents the ultraviolet light strip 30 from being eroded by dust and rain from the outside, and ensures that the ultraviolet light strip 30 can be used normally.

[0044] In the present application, in order to further improve the protection of the ultraviolet light strip 30, a recessed portion 9 is further provided on the door panel, and the recessed portion 9 is used to install two support handles 1 and a rotating handle 2. The setting of the recessed portion 9 effectively protects against rainwater and prevents the ultraviolet light strip 30 from being eroded by rainwater.

[0045] In the present application, the driving assembly includes a rotating screw 40 and a driving motor 41, wherein the rotating screw 40 is inserted between the rotating handle 2 and the two supporting handles 1, and the rotating screw 40 is fixedly connected to the rotating handle 2, and the two ends of the rotating screw 40 are respectively rotatably connected to the two supporting handles 1; the driving motor 41 is installed on one of the supporting handles 1, and the driving motor 41 is connected to the rotating screw 40. When in use, the driving motor 41 is connected to the control system of the central console, and when the driving motor 41 rotates forward and reversely, it can effectively drive the rotating screw 40 to rotate together, and the rotating screw 40 is fixedly connected to the rotating handle 2, and then during the rotation of the rotating screw 40, the rotating handle 2 rotates together. In addition, under the action of the supporting handles 1 at both ends, there is also some axial limiting effect on the rotating handle 2 to avoid axial movement and deviation during the rotation of the rotating handle 2, and the structure is reliable.

[0046] In the present application, in order to conveniently fix the rotating screw 40 to the rotating handle 2, a first chamber 20 is provided in the rotating handle 2, and a mounting plate 21 is fixed to the inner wall of the first chamber 20 by welding, riveting or bolting, and a nut 22 is fixed on the mounting plate 21. The thread direction of the nut 22 matches the thread of the rotating screw 40. The rotating screw 40 is passed through the first chamber 20 and connected to the nut 22, so that the rotating screw 40 and the rotating handle 2 are effectively fixed by threaded connection. In order to strengthen the connection strength between the rotating screw 40 and the rotating handle 2, at least two mounting plates 21 and nuts 22 are provided, and the structure is reliable. The mounting plate 21 and the nut 22 are made of high-strength, corrosion-resistant materials, such as stainless steel or alloy steel. At the same time, the processing accuracy should be strictly controlled to ensure the tightness and stability of the threaded connection.

[0047] In the present application, in order to conveniently connect the rotating screw 40 with the support handle 1, a second chamber 5 is provided in each of the two support handles 1, and a clamping plate 6 is provided in the second chamber 5. The two ends of the rotating screw 40 are respectively connected to the two clamping plates 6 by rotation. The clamping plate 6 is made of high-strength, corrosion-resistant materials, such as stainless steel or alloy steel, to ensure its stability and durability in long-term use. In order to firmly fix the clamping plate 6 on the inner wall of the second chamber 5, welding, bolt connection or riveting can be used. At that time, during the rotation of the rotating screw 40, the rotating screw 40 rotates relative to the clamping plate 6. A clamping groove 60 is also provided on one of the clamping plates 6, and the drive motor 41 is fixed to the clamping groove 60 by clamping, which is convenient for installation. Fixing the drive motor 41 by clamping can greatly simplify the assembly process, reduce installation time and cost, and at the same time, the clamping method also has the characteristics of easy disassembly, which is convenient for subsequent maintenance and repair.

[0048] In the present application, after the support handle 1 and the rotating handle 2 are connected and installed, after long-term use, it is inevitable that the wear and tear between the two will occur. Therefore, in order to avoid deviation between the rotating handle 2 and the support handle 1, when the disinfection program is started, the rotating handle 2 stops after rotating 360 degrees clockwise, and the rotating handle 2 uses a rotary encoder to monitor the rotation angle of the motor. When the disinfection program is started next time, the rotating handle 2 stops after rotating 360 degrees counterclockwise. The implementation method is also to feedback the encoder signal, automatically lock the drive motor 41 after rotating 360 degrees, and automatically determine whether it has rotated 360 degrees during operation. If it does not reach or exceed 360 degrees, the recovery mechanism is triggered to restart the drive motor 41 until the predetermined rotation angle is reached. In addition, if you encounter a situation of strong rotation damage in daily life, you can also add overload protection to the drive motor 41 to automatically cut off the drive motor 41 to prevent mechanical damage caused by external force.

[0049] In the present application, an embedding groove is provided on the inner wall of the second chamber 5, and a waterproof rubber plate 7 is provided in the embedding groove, and the waterproof rubber plate 7 can prevent water from entering the second chamber 5. The waterproof rubber plate 7 is clamped in the embedding groove, so that when the driving motor 41 fails or during routine maintenance, only the waterproof rubber plate 7 needs to be removed, which is convenient to operate.

[0050] In the present application, by providing protective rubber rings 8 at the ends of the two support plates close to the rotating handle 2, the second chamber 5 can be effectively protected and sealed to prevent water vapor or dust from entering from the connection gap between the rotating handle 2 and the supporting handle 1, and the structure is reliable. In addition, the protective rubber ring 8 can also reduce the wear and tear between the rotating handle 2 and the supporting handle and the occurrence of abnormal noise.

[0051] The implementation principle of the present application is: before the passengers get on or off the vehicle, the driving motor 41 and the ultraviolet light strip 30 are controlled to operate, and then, driven by the driving motor 41, the rotating screw 40 effectively drives the rotating handle 2 to rotate. At this time, the ultraviolet light strip 30 performs ultraviolet disinfection on the rotating handle 2, and as the rotating handle 2 rotates, it is fully disinfected, and cleaning is convenient and reliable. Passengers do not need to operate the disinfection by themselves, and centralized control is performed through the vehicle control system to ensure that the safety of each passenger is guaranteed.
