Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle monitoring technology, and in particular to a vehicle monitoring device. Background Technology
[0002] Vehicle monitoring devices, commonly known as dashcams, can record video images and sound of the entire process of a car driving, which can provide evidence. Those who like it can also use it to record the process of overcoming difficulties and obstacles. Under current technology, dashcams are mainly composed of two parts: the dashcam body and the bracket. The bracket is fixed to the windshield by a suction cup.
[0003] In existing technologies, a single suction cup is generally used for connection. This suction cup is usually a large suction cup. Although this design can effectively ensure an extremely stable fit with the glass surface, it is quite inconvenient and laborious in subsequent maintenance, repair, or disassembly operations. Specifically, while this tight connection mechanism ensures the stability of the connection, it also increases the technical difficulty and labor intensity of the disassembly process. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vehicle monitoring device. When in use, the device utilizes contact negative pressure to facilitate the removal of the suction cup from the glass. Furthermore, the suction cup can be replaced individually after long-term use when it ages, thus improving the overall adaptability of the device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A vehicle monitoring device includes a monitoring mechanism, which includes a connecting plate, a connecting shaft rotatably connected to the left side of the connecting plate, and a mounting frame rotatably connected to the other side of the connecting shaft. A monitoring body is mounted on the left side of the mounting frame. A connecting mechanism includes a threaded post fixedly connected to the right side of the connecting plate, a connecting cylinder threadedly connected to the threaded post, and a suction cup fixedly connected to the right side of the connecting cylinder. A negative pressure release mechanism is used to release the negative pressure on the suction cup.
[0007] Preferably, the rotating connection of the connecting shaft mounting frame and the connecting plate both adopt a damped rotating shaft.
[0008] Preferably, an annular sealing gasket is fixedly connected to the right side of the connecting plate, and the annular sealing gasket contacts the left side of the connecting cylinder.
[0009] Preferably, the negative pressure relief mechanism includes a columnar groove vertically formed on the connecting plate, and a connecting channel is provided inside the threaded column.
[0010] Preferably, the right end of the connecting channel is connected to the inside of the suction cup, and the left end of the connecting channel is connected to the inside of the columnar groove.
[0011] Preferably, a piston rod that can slide up and down is provided in the columnar groove. The lower end of the piston rod passes through the columnar groove and is fixedly connected to a connecting plate. The upper end of the connecting plate is elastically connected to the lower end of the connecting plate by a spring.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] 1. The position of the monitoring unit can be adjusted via the connecting shaft to meet the adjustment function.
[0014] 2. Equipped with a negative pressure release mechanism, when it is necessary to separate the suction cup from the glass, simply pull down the connecting plate. At this time, the inside of the suction cup is connected to the outside, the internal negative pressure is released, and the suction cup can be easily removed.
[0015] 3. When the suction cup ages, simply twist the connecting cylinder to unscrew the threaded connection, and then install a new connecting cylinder with a suction cup to complete the replacement. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] It should be noted that in the description of this application, the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0022] Reference Figure 1-3 A vehicle monitoring device includes a monitoring mechanism, which includes a connecting plate 1. A connecting shaft 3 is rotatably connected to the left side of the connecting plate 1, and a mounting frame 4 is rotatably connected to the other side of the connecting shaft 3. A monitoring body 5 is mounted on the left side of the mounting frame 4. The rotatable connection of the connecting shaft 3, the mounting frame 4, and the connecting plate 1 all adopt a damping shaft. The damping shaft is an existing technology, similar to the swivel table on a laptop computer, which has a large damping.
[0023] The system also includes a connecting mechanism, which includes a threaded post 11 fixedly connected to the right side of the connecting plate 1, a connecting cylinder 10 threadedly connected to the threaded post 11, a suction cup 2 fixedly connected to the right side of the connecting cylinder 10, and an annular sealing gasket 13 fixedly connected to the right side of the connecting plate 1. The annular sealing gasket 13 contacts the left side of the connecting cylinder 10, thereby ensuring a tight seal.
[0024] It also includes a negative pressure release mechanism, which is used to release the negative pressure of the suction cup 2. The negative pressure release mechanism includes a columnar groove 6 vertically opened on the connecting plate 1. A connecting channel 12 is provided in the threaded column 11. The right end of the connecting channel 12 is connected to the inside of the suction cup 2, and the left end of the connecting channel 12 is connected to the inside of the columnar groove 6. A piston column 8 that can slide up and down is provided in the columnar groove 6. The piston column 8 has good sealing performance and can seal the left side of the connecting channel 12. The lower end of the piston column 8 passes through the columnar groove 6 and is fixedly connected to the connecting plate 7. The upper end of the connecting plate 7 is elastically connected to the lower end of the connecting plate 1 by a spring 9.
[0025] In this utility model, when in use, the device is attached to the glass by suction cup 2 to complete the positioning. Then, the position of the monitoring body 5 can be adjusted by connecting shaft 3 to meet the adjustment function.
[0026] When it is necessary to separate the suction cup 2 from the glass, simply pull down the connecting plate 7 to move the piston column 8 down, thereby connecting the left side of the connecting channel 12 with the upper part of the columnar groove 6. At this time, the inside of the suction cup 2 is connected to the outside, the internal negative pressure is released, and the suction cup 2 can be removed relatively easily.
[0027] When the suction cup 2 ages, simply twist the connecting cylinder 10 to unscrew it through the thread; then install a new connecting cylinder 10 with the suction cup 2 to complete the replacement.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
