[0001] The utility model belongs to the technical field of road sign recognition, and in particular relates to a road sign recognition vision acquisition device. Background Art

[0002] With the continuous development of the national economy, the mileage of highways in my country has been increasing. At the same time, with the continuous progress and development of science and technology, the speed of cars is getting higher and higher. When a car is driving on the road, due to the high speed or the driver's negligence, it is very likely that the driver will miss the road signs and cannot clearly identify the driving road, causing driving inconvenience or driving danger.

[0003] In order to assist the driver in identifying road signs while driving, a road sign recognition visual acquisition device is installed on the vehicle to identify the signs on the road during the vehicle's driving process, so as to help the driver make accurate judgments on the road signs, thereby assisting the driver in driving safety.

[0004] However, the existing road sign recognition visual acquisition device is difficult to disassemble and assemble after installation. At the same time, since it is usually installed on the front windshield, the installation space is limited. When using the visual acquisition device, it is necessary to insert and remove the memory card and perform maintenance. The inconvenient disassembly and assembly and the limited installation space make the visual acquisition device inconvenient to operate.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0006] The utility model aims to provide a road sign recognition visual acquisition device, which can solve the problem of inconvenient operation of the visual acquisition device due to limited installation space.

[0007] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0008] A road sign recognition visual acquisition device, comprising:

[0009] The visual acquisition component comprises a visual acquisition device body, on which a U-shaped mounting seat is mounted; the U-shaped mounting seat is used to mount the visual acquisition device body, so that the visual acquisition device body is easy to mount;

[0010] The installation assembly comprises an installation box, a slide groove is provided in the installation box, an upper side wall plate of the U-shaped installation seat is slidably connected in the slide groove, a installation seat is fixedly connected to the slide groove, a damping shaft is provided on the installation seat, and a rotating sleeve is rotatably connected to the damping shaft; the U-shaped installation seat is conveniently disassembled and assembled by installing the U-shaped installation seat and the slide groove in a sliding connection; with the cooperation of the damping shaft and the rotating sleeve, the installation box can adjust the angle as needed when in use;

[0011] The limiting assembly includes a limiting hole, the limiting hole is formed on the side wall of the installation box, a movable groove is formed on the side wall of the slide slot, the limiting hole corresponds to the position of the movable groove, a clamping rod is slidably connected in the movable groove, and one end of the clamping rod close to the side wall of the installation box is placed in the limiting hole. By placing the front end of the clamping rod in the limiting hole, the movement of the U-shaped mounting seat after being slidably connected in the slide slot is limited, thereby ensuring stability after installation.

[0012] In one or more embodiments of the present invention, both side walls of the upper end wall plate of the U-shaped mounting seat are fixedly connected with limiting rods, and both side walls of the slide slot are provided with limiting slots, and the limiting rods are sleeved in the limiting slots. Through the cooperation between the limiting rods and the limiting slots, the U-shaped mounting seat is stable when it is slidably connected in the slide slot.

Through the cooperation of the suction cup and the adhesive layer, the installation assembly can be installed on the front windshield of the vehicle to ensure stability after installation.

[0014] In one or more embodiments of the utility model, one end of the clamping rod placed in the limiting hole is set to a wedge shape, and the wedge shape set at one end of the clamping rod matches the direction in which the U-shaped mounting seat is slidably connected in the slide groove. Since the clamping rod is slidably connected in the movable groove, the wedge shape set on the clamping rod matches the direction in which the U-shaped mounting seat is installed and slid, so that when the U-shaped mounting seat slides in the slide groove, the clamping rod will be pushed to slide into the movable groove, so that the U-shaped mounting seat can continue to slide in the slide groove.

[0015] In one or more embodiments of the utility model, a compression spring is installed in the movable groove, and the compression spring is installed at the end of the clamping rod away from the wedge. Since the clamping rod is used to limit the sliding of the slide groove in the U-shaped mounting seat, the front end of the clamping rod needs to be placed in the limiting hole during installation. Therefore, by providing a compression spring, when the clamping rod slides to the position of the limiting hole, the compression spring can push the front end of the clamping rod into the limiting hole.

[0016] In one or more embodiments of the utility model, a push rod is slidably connected in the limiting hole, one end of the push rod is placed outside the installation box, and the other end of the push rod is placed in the limiting hole. By pushing the push rod, the clamping rod can be driven to slide into the movable groove.

[0017] In one or more embodiments of the present utility model, one end of the push rod placed in the limiting hole is fixedly connected to a first limiting plate, and a second limiting plate is fixedly connected to the limiting hole.

[0018] In one or more embodiments of the present invention, the push rod is slidably connected in the second limit plate, and the first limit plate is arranged on the left side of the second limit plate. The cooperation between the first limit plate and the second limit plate prevents the push rod from sliding out of the limit hole.

[0019] Compared with the prior art, the utility model makes it easy to assemble and disassemble the visual acquisition device while being stably installed by setting an installation component and a limit component. Therefore, when it is inconvenient to operate the visual acquisition device in a limited space, the visual acquisition device can be removed for operation and then reinstalled after the operation is completed, making it convenient to operate the visual acquisition device.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figure 1 to Figure 6 As shown, a road sign recognition visual acquisition device in one embodiment of the utility model includes a visual acquisition component 1, an installation component 2 and a limiting component 3.

[0031] like Figure 1 to Figure 4 As shown, the visual acquisition component 1 includes a visual acquisition device body 11, on which a U-shaped mounting seat 12 is installed; the U-shaped mounting seat 12 is used to install the visual acquisition device body 11, so that the installation of the visual acquisition device body 11 is convenient.

[0032] like Figure 1 to Figure 4 As shown, the mounting assembly 2 includes a mounting box 21, a slide groove 22 is provided in the mounting box 21, the upper side wall plate of the U-shaped mounting seat 12 is slidably connected in the slide groove 22, a mounting seat 24 is fixedly connected to the slide groove 22, a damping shaft 25 is provided on the mounting seat 24, and a rotating sleeve 26 is rotatably connected to the damping shaft 25; by installing the U-shaped mounting seat 12 and the slide groove 22 in a sliding connection manner, the U-shaped mounting seat 12 is easy to disassemble and assemble; with the cooperation of the damping shaft 25 and the rotating sleeve 26, the mounting box 21 can adjust the angle as needed when in use.

[0033] Specifically, by installing a U-shaped mounting seat 12 on the visual acquisition device body 11, and by slidingly connecting the upper side wall plate of the U-shaped mounting seat 12 in the slide groove 22, the U-shaped mounting seat 12 can be installed on the installation box 21. Due to the sliding connection, the U-shaped mounting seat 12 and the slide groove 22 are easy to disassemble and assemble, thereby making the visual acquisition device body 11 easy to disassemble and assemble. At the same time, after installation, since the visual acquisition device body 11 needs to adjust its angle according to the acquisition requirements, the angle of the installation box 21 is adjusted by the cooperation of the damping shaft 25 and the rotating sleeve 26, thereby adjusting the angle of the U-shaped mounting seat 12, and then adjusting the angle of the visual acquisition device body 11.

[0034] like Figure 1 and Figure 4 As shown, the limiting rods 13 are fixedly connected to both side walls of the upper end wall plate of the U-shaped mounting seat 12, and the limiting grooves 23 are provided on both side walls of the slide groove 22, and the limiting rods 13 are sleeved in the limiting grooves 23. Through the cooperation between the limiting rods 13 and the limiting grooves 23, the U-shaped mounting seat 12 is stable when it is slidably connected in the slide groove 22.

[0035] like Figure 2 As shown, a connecting rod 27 is fixedly connected to the rotating sleeve 26, and a suction cup 28 is fixedly connected to one end of the connecting rod 27 away from the rotating sleeve 26, and an adhesive layer 29 is arranged in the suction cup 28. Through the cooperation of the suction cup 28 and the adhesive layer 29, the mounting assembly 2 can be installed on the front windshield of the vehicle to ensure stability after installation.

[0036] like Figure 4 and Figure 6 As shown, the limiting assembly 3 includes a limiting hole 31, which is provided on the side wall of the installation box 21, and a movable groove 33 is provided on the side wall of the slide groove 22. The limiting hole 31 corresponds to the position of the movable groove 33, and a clamping rod 32 is slidably connected in the movable groove 33, and one end of the clamping rod 32 close to the side wall of the installation box 21 is placed in the limiting hole 31. By placing the front end of the clamping rod 32 in the limiting hole 31, the movement of the U-shaped mounting seat 12 after being slidably connected in the slide groove 22 is limited, thereby ensuring stability after installation.

[0037] like Figure 6 As shown, one end of the clamping rod 32 placed in the limiting hole 31 is set to a wedge shape, and the wedge shape set at one end of the clamping rod 32 matches the direction in which the U-shaped mounting seat 12 is slidably connected in the sliding groove 22. Since the clamping rod 32 is slidably connected in the movable groove 33, the wedge shape set in the clamping rod 32 matches the installation and sliding direction of the U-shaped mounting seat 12, so that when the U-shaped mounting seat 12 slides in the sliding groove 22, the clamping rod 32 will be pushed to slide into the movable groove 33, so that the U-shaped mounting seat 12 can continue to slide in the sliding groove 22.

[0038] like Figure 6 As shown, a compression spring 34 is installed in the movable groove 33, and the compression spring 34 is installed at the end of the clamping rod 32 away from the wedge. Since the clamping rod 32 is used to limit the sliding of the slide groove 22 in the U-shaped mounting seat 12, the front end of the clamping rod 32 needs to be placed in the limiting hole 31 during installation. Therefore, by providing the compression spring 34, when the clamping rod 32 slides to the position of the limiting hole 31, the compression spring 34 can push the front end of the clamping rod 32 into the limiting hole 31.

[0039] like Figure 6 As shown, a push rod 35 is slidably connected in the limiting hole 31, one end of the push rod 35 is placed outside the installation box 21, and the other end of the push rod 35 is placed in the limiting hole 31. By pushing the push rod 35, the clamping rod 32 can be driven to slide into the movable groove 33.

[0040] like Figure 6 As shown, one end of the push rod 35 placed in the limiting hole 31 is fixedly connected to the first limiting plate 36, and the limiting hole 31 is fixedly connected to the second limiting plate 37. The push rod 35 is slidably connected to the second limiting plate 37, and the first limiting plate 36 is arranged on the left side of the second limiting plate 37. The cooperation between the first limiting plate 36 and the second limiting plate 37 prevents the push rod 35 from sliding out of the limiting hole 31.

[0041] When in use, the visual acquisition device body 11 is installed on the lower end of the U-shaped mounting seat 12, and the upper side wall plate of the U-shaped mounting seat 12 is slidably connected to the mounting box 21. When the U-shaped mounting seat 12 slides in the slide groove 22, the wedge surface of the clamping rod 32 will contact the side wall of the slide groove 22, so that the clamping rod 32 will slide into the movable groove 33. When sliding, the clamping rod 32 will compress the compression spring 34. When the clamping rod 32 shrinks into the movable groove 33, the U-shaped mounting seat 12 can continue to slide in the slide groove 22. When the U-shaped mounting seat 12 slides to the position of the clamping rod 32 corresponding to the position of the limiting hole 31, the compression spring 34 will push the clamping rod 32 to slide, so that one end of the wedge of the clamping rod 32 extends into the limiting hole 31, and the clamping rod 32 can be used to limit the sliding of the U-shaped mounting seat 12 in the slide groove 22, so that the visual acquisition device body 11 is stable after installation.

[0042] When the visual acquisition device body 11 is to be operated such as inserting and removing the memory card and performing maintenance, if the installation space makes it inconvenient to operate, the push rod 35 can be squeezed so that the push rod 35 can slide into the limiting hole 31, and the push rod 35 can push the clamping rod 32 to slide into the movable groove 33. When the clamping rod 32 shrinks into the movable groove 33, the U-shaped mounting seat 12 can be pulled out from the slide groove 22, so that the visual acquisition device body 11 can be removed for operation, which makes the operation convenient. After the operation is completed, the U-shaped mounting seat 12 can be put back into the slide groove 22.

[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
