Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a windshield wiper device and a camera. Background Technology

[0002] When surveillance cameras and other equipment are used outdoors for extended periods, rainwater, impurities, and other foreign objects on the viewing window surface can affect the camera's imaging.

[0003] In existing technologies, windshield wipers are typically used to clean the window surface to ensure imaging quality. However, windshield wipers are prone to loosening during rotation, resulting in poor oscillation accuracy and affecting their cleaning effect on the window surface. Utility Model Content

[0004] Therefore, it is necessary to provide a windshield wiper device and a camera to address the above problems and ensure the rotation accuracy of the windshield wiper.

[0005] This utility model first provides a windshield wiper device, comprising: a wiper component; a frame assembly, including an outer frame and a locking member, the outer frame being connected to the wiper component, the outer frame including a first sidewall and two second sidewalls oppositely disposed on both sides of the first sidewall, the first sidewall and the two second sidewalls forming an installation space, the locking member being connected to the two second sidewalls; a rotating shaft assembly, including a shaft and a mounting member disposed at one end of the shaft, the mounting member including two opposing first mounting surfaces, the mounting member extending into the installation space and being fixedly connected to the first sidewall by a first fastener, the two first mounting surfaces facing the two second sidewalls respectively, so that the locking member can pull the two second sidewalls tight to fit against the two first mounting surfaces respectively; and a drive assembly, connected to the end of the shaft away from the mounting member, and capable of driving the rotating shaft assembly to rotate.

[0006] In the aforementioned wiper device, the mounting component is fixed to the first sidewall by a first fastener to prevent the rotating shaft assembly from moving relative to the outer frame in a direction perpendicular to the first sidewall. The locking component pulls the two second sidewalls tight to fit against the two first mounting surfaces respectively, so that the two second sidewalls can clamp and fix the mounting component, preventing the rotating shaft assembly from moving relative to the outer frame in a direction perpendicular to the second sidewall. This achieves a gapless fit between the rotating shaft assembly and the outer frame, preventing the wiper component from being inaccurately positioned due to the frame assembly and wiper component wobbling relative to the rotating shaft assembly when the drive assembly drives the rotating shaft assembly, frame assembly, and wiper component to rotate and stop. This improves the stability and reliability of the connection between the rotating shaft assembly and the outer frame, ensures the rotational accuracy of the wiper component, and thus ensures the cleaning effect of the wiper device. At the same time, it can also reduce the probability of damage to the wiper device during transportation and use.

[0007] In one embodiment, the frame assembly further includes an inner frame disposed within the mounting space, the inner frame being slidable relative to the outer frame in a direction perpendicular to the first sidewall; the wiper component is disposed on the side of the inner frame opposite to the first sidewall, and at least a portion of the wiper component extends out of the mounting space.

[0008] With this design, the inner frame can easily fix the wiper component, and the wiper component can slide together with the inner frame relative to the outer frame in a direction perpendicular to the first side wall, so that the wiper component can fit tightly against the window surface and ensure the cleaning effect of the wiper component on the window surface.

[0009] In one embodiment, the skeleton assembly further includes an elastic member disposed between the first sidewall and the inner skeleton, the elastic member being compressed when the inner skeleton slides toward the first sidewall.

[0010] This design allows the wiper blades to fit snugly against the window surface and maintain a certain pressure on it, thereby improving the cleaning effect of the wiper blades on the window surface. Furthermore, the elastic element is built into the installation space, making it highly resistant to damage, with a simple structure, easy installation, and low cost.

[0011] In one embodiment, one of the first sidewall and the inner frame is provided with a limiting post extending in a direction perpendicular to the first sidewall, and the other is provided with a limiting hole for passing through the limiting post, and the elastic element is sleeved on the limiting post.

[0012] With this configuration, the limiting post can limit the elastic element, preventing both ends of the elastic element from detaching from the first sidewall and the inner frame; the limiting post can also restrict the sliding direction of the inner frame and the wiper component, so that the inner frame and the wiper component can always slide in a direction perpendicular to the first sidewall.

[0013] In one embodiment, the number of elastic elements is at least two, and each elastic element is arranged at intervals along the length direction of the inner skeleton.

[0014] This design ensures the balance of force applied by the elastic element to the inner frame and the wiper component, ensuring that the wiper component can fit snugly against the window surface and guaranteeing the cleaning effect of the wiper component on the window surface.

[0015] In one embodiment, the second sidewall has a waist-shaped hole extending in a direction perpendicular to the first sidewall, and the frame assembly further includes a second fastener that passes through the waist-shaped hole and is fixedly connected to the inner frame and the wiper assembly, and the second fastener is slidable relative to the waist-shaped hole.

[0016] With this configuration, the second fastener, in conjunction with the oblong hole, can restrict the sliding direction and range of the inner frame and the wiper component, allowing the inner frame and the wiper component to always slide in a direction perpendicular to the first sidewall, and preventing the inner frame and the wiper component from coming off the outer frame as a whole; the second fastener can also fix the inner frame and the wiper component.

[0017] In one embodiment, the number of waist-shaped holes is at least two, and each of the waist-shaped holes is arranged at intervals along the length direction of the inner skeleton.

[0018] This design prevents the second fastener from rotating within the oblong hole, which could cause one end of the wiper blade to easily lift and become damaged. This ensures that the entire wiper blade remains firmly attached to the window surface, guaranteeing its cleaning effect.

[0019] In one embodiment, the wiper component includes a fixing part and a wiper part connected to each other, the inner frame covers the outer periphery of the fixing part, one of the inner frame and the fixing part is provided with a slot, and the other is provided with a snap-fit ​​part that can engage with the slot.

[0020] This design, where the snap-fit ​​part engages with the slot, restricts the movement of the wiper component relative to the inner frame, ensuring the stability and reliability of the connection between the inner frame and the wiper component.

[0021] In one embodiment, the locking member includes a screw portion and a nut portion, the screw portion being able to pass through the two second sidewalls in sequence and be threadedly connected to the nut portion; and / or, the mounting member further includes a second mounting surface at one end away from the shaft, the second mounting surface being in contact with the first sidewall.

[0022] This design simplifies the structure of the locking component, making it easier to process and assemble; the second mounting surface improves the stability and reliability of the connection between the shaft assembly and the outer frame.

[0023] This utility model also provides a camera, including: a camera body including a viewing window; and a wiper device as described above, disposed on the camera body, the wiper being used to clean the outer surface of the viewing window. Attached Figure Description

[0040] When surveillance cameras and other equipment are used outdoors for extended periods, rainwater, impurities, and other foreign objects on the viewing window surface can affect the camera's image quality. In existing technologies, windshield wipers are typically used to clean the viewing window surface to ensure image quality. However, windshield wipers are prone to loosening during rotation, resulting in poor wiper oscillation precision and thus affecting their cleaning effectiveness on the viewing window surface.

[0041] To solve the above problems, such as Figures 1 to 9 As shown, this utility model first provides a windshield wiper device to ensure the rotation accuracy of the windshield wiper.

[0042] like Figure 1 , Figure 3 and Figure 4 As shown, specifically, the wiper assembly includes a wiper component 1, a frame assembly 2, a pivot assembly 3, and a drive assembly 4. The frame assembly 2 includes an outer frame 21 and a locking member 22. The outer frame 21 is connected to the wiper component 1. The outer frame 21 includes a first sidewall 211 and two second sidewalls 212 oppositely disposed on both sides of the first sidewall 211. The first sidewall 211 and the two second sidewalls 212 enclose an installation space. The locking member 22 is connected to the two second sidewalls 212. The pivot assembly 3 includes a shaft 31 and a drive assembly 4. A mounting member 32 is placed at one end of the shaft 31. The mounting member 32 includes two opposing first mounting surfaces 321. The mounting member 32 extends into the mounting space and is fixedly connected to the first side wall 211 by a first fastener 23. The two first mounting surfaces 321 face the two second side walls 212 respectively, so that the locking member 22 can pull the two second side walls 212 to fit against the two first mounting surfaces 321 respectively. The drive assembly 4 is connected to the end of the shaft 31 away from the mounting member 32 and can drive the rotating shaft assembly 3 to rotate.

[0043] In the wiper device provided in this embodiment of the utility model, the wiper device can be used in devices such as cameras that can clean the surface of the window through the wiper component 1. When the drive component 4 drives the rotating shaft component 3 to rotate, the rotating shaft component 3 can drive the frame component 2 and the wiper component 1 to rotate together. The rotation range of the wiper component 1 covers the surface of the window, and the wiper component 1 can be in close contact with the surface of the window, so that rainwater, impurities and other foreign objects on the surface of the window can be cleaned through the wiper component 1. Furthermore, the mounting component 32 is fixed to the first sidewall 211 by the first fastener 23 to prevent the rotating shaft assembly 3 from moving relative to the outer frame 21 in a direction perpendicular to the first sidewall 211. The locking component 22 pulls the two second sidewalls 212 tight to fit against the two first mounting surfaces 321 respectively, so that the two second sidewalls 212 can clamp and fix the mounting component 32, preventing the rotating shaft assembly 3 from moving relative to the outer frame 21 in a direction perpendicular to the second sidewalls 212. This achieves a gapless fit between the rotating shaft assembly 3 and the outer frame 21, preventing the wiper component 1 from being inaccurately positioned due to the wobbling of the frame assembly 2 and the wiper component 1 relative to the rotating shaft assembly 3 when the drive assembly 4 drives the rotating shaft assembly 3, the frame assembly 2, and the wiper component 1 to rotate and stop. This improves the stability and reliability of the connection between the rotating shaft assembly 3 and the outer frame 21, ensures the rotational accuracy of the wiper component 1, and thus ensures the cleaning effect of the wiper device. At the same time, it can also reduce the probability of damage to the wiper device during transportation and use.

[0044] The first fastener 23 can be configured as a fastening element such as a screw or bolt.

[0045] like Figure 4 and Figure 8 As shown, in one embodiment, the locking member 22 includes a screw portion 221 and a nut portion 222. The screw portion 221 can pass through two second sidewalls 212 in sequence and then be threadedly connected to the nut portion 222. When the screw portion 221 and the nut portion 222 are threadedly connected, the end of the screw portion 221 and the nut portion 222 can respectively press the two second sidewalls 212 towards the middle from the outside of the two second sidewalls 212, so that the two second sidewalls 212 can respectively fit tightly against the two first mounting surfaces 321. In this way, the locking member 22 has a simple structure, which facilitates processing and assembly. The nut portion 222 can also be fixedly connected to the outer surface of one of the second sidewalls 212, and the screw portion 221 passes through the two second sidewalls 212 in sequence from the outer surface of the other second sidewall 212 and is threadedly connected to the nut portion 222. Of course, in other embodiments, the locking member 22 can also be other clamping structures, as long as it can apply a force toward the middle to the two second side walls 212 so that the two second side walls 212 can be tightly attached to the two first mounting surfaces 321 respectively. This utility model embodiment does not make specific limitations here.

[0046] like Figure 1 and Figure 4As shown, in one embodiment, the axis of the shaft 31 is perpendicular to the first sidewall 211, and the drive assembly 4 can drive the rotating shaft assembly 3 to rotate around the axis of the shaft 31. The mounting member 32 also includes a second mounting surface 322 at one end away from the shaft 31, which is in contact with the first sidewall 211. The second mounting surface 322 can increase the contact area between the mounting member 32 and the first sidewall 211, further preventing the rotating shaft assembly 3 from moving relative to the outer frame 21 in a direction perpendicular to the first sidewall 211, and improving the stability and reliability of the connection between the rotating shaft assembly 3 and the outer frame 21. Of course, in other embodiments, the axis of the shaft 31 can also be parallel to the first sidewall 211 or form an angle with the first sidewall 211, and the drive assembly 4 can also drive the rotating shaft assembly 3 to rotate around other axes. Specifically, it can be adjusted according to the arrangement of the wiper component 1 and the window surface. This embodiment of the present invention does not impose specific limitations here.

[0047] like Figures 2 to 3 As shown, the frame assembly 2 also includes an inner frame 24 disposed within the installation space. The inner frame 24 is slidable relative to the outer frame 21 in a direction perpendicular to the first sidewall 211. The wiper component 1 is disposed on the side of the inner frame 24 facing away from the first sidewall 211, with at least a portion of the wiper component 1 extending out of the installation space. Since the wiper component 1 is generally made of flexible materials such as rubber or silicone, the inner frame 24 can easily fix the wiper component 1, and the wiper component 1 can slide together with the inner frame 24 relative to the outer frame 21 in a direction perpendicular to the first sidewall 211, allowing the wiper component 1 to fit tightly against the window surface and ensuring the cleaning effect of the wiper component 1 on the window surface.

[0048] like Figure 5 As shown, the inner frame 24 includes a third sidewall 243 and two fourth sidewalls 244 disposed opposite to each other on both sides of the third sidewall 243. The wiper component 1 includes a fixing part 11 and a wiper part 12 connected to each other. The third sidewall 243 and the two fourth sidewalls 244 cover the outer periphery of the fixing part 11. The fixing part 11 is used for fixed connection with the inner frame 24, and the wiper part 12 is used for cleaning the surface of the window.

[0049] like Figure 5As shown, one of the inner frame 24 and the fixing part 11 is provided with a slot 111, and the other is provided with a locking part 242 that can engage with the slot 111. In the illustrated embodiment, the fourth side wall 244 has a locking part 242 protruding inward at the end away from the third side wall 243, and the fixing part 11 is provided with a slot 111. Both the locking part 242 and the slot 111 extend along the length direction of the inner frame 24. In the assembled state, the locking part 242 is engaged in the slot 111 to restrict the movement of the wiper component 1 relative to the inner frame 24 in a direction perpendicular to the third side wall 243, thereby ensuring the stability and reliability of the connection between the inner frame 24 and the wiper component 1. Of course, in other embodiments, the locking part 242 and the slot 111 may also extend in a direction perpendicular to the third side wall 243 or in a direction at other angles to the third side wall 243, as long as the movement of the wiper component 1 relative to the inner frame 24 can be restricted. This embodiment of the present invention does not impose specific limitations here. Furthermore, the inner frame 24 and the wiper component 1 can be fixedly connected by fastening elements such as screws, bolts, and pins to further improve the stability and reliability of the connection between the inner frame 24 and the wiper component 1.

[0050] like Figure 3 and Figure 7 As shown, the frame assembly 2 also includes an elastic element 25 disposed between the first sidewall 211 and the inner frame 24. When the inner frame 24 slides toward the first sidewall 211, the elastic element 25 is compressed. The elastic element 25 can apply an elastic force toward the window surface to the inner frame 24 and the wiper component 1, so that the wiper component 1 can adhere tightly to the window surface and maintain a certain squeezing force on the window surface, thereby improving the cleaning effect of the wiper component 1 on the window surface. Furthermore, the elastic element 25 is built into the installation space, has strong resistance to damage, simple structure, convenient installation, and low cost. The elastic element 25 can be set as a spring, disc spring, silicone rubber component, or other elastic element.

[0051] like Figures 6 to 8As shown, one of the first sidewall 211 and the inner frame 24 is provided with a limiting post 213 extending in a direction perpendicular to the first sidewall 211, and the other is provided with a limiting hole 241 for the limiting post 213 to pass through. The elastic member 25 is sleeved on the limiting post 213. The limiting post 213 can limit the elastic member 25 to prevent the two ends of the elastic member 25 from disengaging from the first sidewall 211 and the inner frame 24; in addition, the limiting post 213 can also restrict the sliding direction of the inner frame 24 and the wiper component 1, so that the inner frame 24 and the wiper component 1 can always slide in a direction perpendicular to the first sidewall 211. In the illustrated embodiment, the first sidewall 211 is provided with a limiting post 213, the third sidewall 243 of the inner frame 24 is provided with a limiting hole 241, and the fixing part 11 of the wiper component 1 is provided with a clearance hole 112 corresponding to the limiting hole 241. When the inner frame 24 and the wiper component 1 slide toward the first sidewall 211, the limiting post 213 can extend into the limiting hole 241 and the clearance hole 112 to prevent the fixing part 11 and the limiting post 213 from interfering with each other and affecting the sliding range of the inner frame 24 and the wiper component 1.

[0052] like Figure 3 and Figure 6 As shown, there are at least two elastic elements 25, and each elastic element 25 is arranged at intervals along the length of the inner frame 24. At least two elastic elements 25 ensure the balance of force applied by the elastic elements 25 to the inner frame 24 and the wiper component 1, preventing one end of the wiper component 1 from easily lifting and being damaged due to only one elastic element 25. This ensures that the wiper component 1 can fit snugly against the window surface, guaranteeing the cleaning effect of the wiper component 1 on the window surface. Alternatively, there can be two, three, or more elastic elements 25. Two elastic elements 25 can ensure the balance of force applied by the elastic elements 25 to the inner frame 24 and the wiper component 1 while avoiding increasing the overall complexity of the wiper device structure.

[0053] like Figure 6 and Figure 8 As shown, the number of limiting posts 213 is the same as the number of elastic elements 25, and they are arranged in a one-to-one correspondence with the elastic elements 25, so as to limit each elastic element 25 by means of the limiting posts 213.

[0054] like Figures 2 to 3As shown, the second sidewall 212 has an oblong hole 214 extending in a direction perpendicular to the first sidewall 211. The frame assembly 2 also includes a second fastener 26, which passes through the oblong hole 214 and is fixedly connected to the inner frame 24 and the wiper component 1. The second fastener 26 can slide relative to the oblong hole 214. The cooperation between the second fastener 26 and the oblong hole 214 restricts the sliding direction and range of the inner frame 24 and the wiper component 1, ensuring that the inner frame 24 and the wiper component 1 can always slide in a direction perpendicular to the first sidewall 211 and preventing the inner frame 24 and the wiper component 1 from detaching from the outer frame 21. Furthermore, the second fastener 26 also serves to fix the inner frame 24 and the wiper component 1, restricting the movement of the wiper component 1 relative to the inner frame 24 and ensuring the stability and reliability of the connection between the inner frame 24 and the wiper component 1. In the illustrated embodiment, each of the two second sidewalls 212 is provided with a waist-shaped hole 214, and the waist-shaped holes 214 on the two second sidewalls 212 are arranged correspondingly. The second fastener 26 includes a pin portion 261 and a retaining ring portion 262. The pin portion 261 passes through the waist-shaped hole 214 on one of the second sidewalls 212, one of the fourth sidewalls 244, the fixing portion 11, the other fourth sidewall 244, and the waist-shaped hole 214 on the other second sidewall 212 in sequence, and is then fixedly connected to the retaining ring portion 262. The retaining ring portion 262 can prevent the pin portion 261 from falling out of the outer frame 21, the inner frame 24, and the wiper component 1, and at the same time can prevent the inner frame 24 and the wiper component 1 from sliding relative to the outer frame 21 due to excessive friction between the second fastener 26 and the outer frame 21. Of course, in other embodiments, only one of the second sidewalls 212 may have a waist-shaped hole 214, and the second fastener 26 may also be set as a screw, nut or other fastening structure, as long as it can ensure that the second fastener 26 can slide in the waist-shaped hole 214 and fix the inner frame 24 and the wiper 1. This utility model embodiment does not make specific limitations here.

[0055] like Figure 3 and Figure 8 As shown, there are at least two oblong holes 214, and each oblong hole 214 is arranged at intervals along the length of the inner frame 24. The at least two oblong holes 214 can prevent the second fastener 26 from rotating within the oblong holes 214, which would cause one end of the wiper component 1 to easily lift and be damaged, thereby ensuring that the wiper component 1 can fit tightly against the window surface intact, and ensuring the cleaning effect of the wiper component 1 on the window surface.

[0056] like Figure 1As shown, the drive assembly 4 includes a bracket 41, a motor 42, a coupling 43, and a control board 44. The bracket 41 is used to fix the drive assembly 4 to equipment such as a camera. The motor 42 is mounted on the bracket 41. The end of the shaft 31 away from the mounting part 32 is connected to the motor 42 through the coupling 43 to transmit rotational torque through the coupling 43. The control board 44 is mounted on the bracket 41 and electrically connected to the motor 42 to control the operation of the motor 42.

[0057] like Figure 9 As shown, this utility model embodiment also provides a camera, including a camera body 5 and the aforementioned wiper device. The camera body 5 includes a viewing window 51, and the wiper component 1 is used to clean the outer surface of the viewing window 51. Specifically, the drive assembly 4 is disposed inside the camera body 5. One end of the shaft 31 with the mounting member 32 extends out of the camera body 5 and is connected to one end of the frame assembly 2. The wiper component 1 is disposed facing the camera body 5 and can be in close contact with the outer surface of the viewing window 51. The drive assembly 4 can drive the rotating shaft assembly 3, the frame assembly 2 and the wiper component 1 to reciprocate within a preset range, so that the rotation range of the wiper component 1 covers the outer surface of the viewing window 51, thereby cleaning rainwater, impurities and other foreign objects on the outer surface of the viewing window 51 through the wiper component 1.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
