Description

Technical Field

[0001] The invention relates to the technical field of traffic warnings, in particular to a right turn reminding device for large vehicles. Background Art

[0002] When large vehicles turn, they have many blind spots and pedestrians lack knowledge of the turning trajectory of the vehicles, which makes it easy for the vehicles to have accidents when turning. Therefore, some intersections where large vehicles travel more often are usually equipped with corresponding turning reminder devices. The turning reminder devices are used to warn drivers and pedestrians to reduce the occurrence of accidents. The Chinese invention patent with publication number CN109371872A discloses a right turn safety reminder device for large vehicles. The column is a hollow structure, and a control box is fixed in the column by installing an angle code. An electronic display screen and a projection lamp are arranged in the warning box. The projection lamp is installed in the outer cover of the projection lamp, and the opening direction of the outer cover of the projection lamp faces downward. A speaker is also installed in the column. The control box is connected to the electronic display screen, the projection lamp and the speaker through a waterproof connector and a cable. The beneficial effects of the present invention are: the right-turning vehicle is reminded by sound (speaker), light (electronic display screen) and shadow (projection lamp), and combined with the Internet of Things control system, an early warning effect of the right turn of large vehicles is achieved, and the accident rate is reduced.

[0003] In the related technology, most of the existing turn reminder devices are installed in a fixed installation manner on the ground, so that the device and the ground form a flat surface. Although the stability of the turn reminder device during operation is guaranteed, the device is prone to breakage when it encounters a vehicle scratch or collision, causing damage to the device. Due to improper driving or drunk driving by the driver, the vehicle is prone to collision with the device, and the existing turn reminder device lacks anti-collision function, so that when a collision occurs, the device installation is prone to breakage, resulting in a high-speed fall, which in turn causes damage to the equipment, making subsequent maintenance difficult and inconvenient for operation. Summary of the invention

[0038] 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0041] The installation frame is provided to improve the stability of the installation of the reminder device. During installation, the installation frame, the bottom frame 1 and the movable block 2 are installed on the ground by pouring concrete, and the top of the movable block 2 is slightly higher than the ground by one to five centimeters, so that the movable block 2 can protrude upward, and the reminder component 6 and the connecting frame 5 can be subjected to impact force, and the bending can be smooth, so as to prevent the whole device from breaking.

[0042] The limit rod 9 is made of a material that can be broken when encountering pressure in the prior art, so that when the reminder device causes a collision, the limit rod 9 can be broken, so that the reminder part and the installation part in the reminder device lose the locking, and then the device is tilted according to the collision direction, which improves the anti-collision effect of the reminder device and reduces the damage to the device during the collision. In addition, during the later maintenance, only the damaged limit rod 9 needs to be replaced to continue the reminder work, which has low maintenance cost and is easy to operate. The bearing force of the limit rod 9 can be set according to the actual situation. For example, if the force is greater than five kilograms, it can prevent damage caused by personnel supporting;

[0043] When the connecting frame 5 or the reminding component 6 is hit by a vehicle, the impact force may squeeze the connecting frame 5 or the reminding component 6, and a plurality of limit rods 9 used to limit the installation position may break, and the locking of the installation position may be lost. At this time, the reminding device may be adaptively tilted according to the impact situation;

[0044] The problem that the reminder device in the prior art is usually installed on the ground in a fixed manner, so that when the reminder device is hit by a vehicle, the reminder device is prone to large-scale bending damage and the internal electrical components are damaged due to the bending phenomenon is solved;

[0045] When the reminder device falls over, the ball 3 can roll inside the spherical groove, thereby driving the touch rod 12 to deviate and lose contact with the switch assembly 11, so that the switch assembly 11 can turn on the alarm 15 to form an alarm communication operation, further improving the anti-collision effect of the reminder device.

[0046] Refer to the attached Figure 3 and Figure 4 , a control module 13 and a wireless communication module 14 are fixedly installed inside the connection frame 5, an alarm 15 is arranged on the front of the connection frame 5, an annular sealing sleeve 16 is fixedly connected to the top of the movable block 2, an embedded groove is provided on the inner surface of the spherical groove, and an elastic clamping sleeve 17 is fixedly connected to the inside of the embedded groove, and the elastic clamping sleeve 17 and the annular sealing sleeve 16 are both wrapped around the outer surface of the sphere 3;

[0050] The touch switch 112 uses the prior art to turn off the alarm 15 by pressing downward; conversely, by losing the pressure on the touch switch 112, the touch switch 112 can turn on the alarm 15;

[0051] The two guide rods 113 are provided to improve the smoothness and stability of the up-and-down movement of the lifting plate 111. The elastic force of the elastic member 114 can be used to press the lifting plate 111 upward, so that the touch switch 112 on the top of the lifting plate 111 contacts the bottom end of the touch rod 12, thereby improving the control effect of the touch switch 112.

[0052] The elastic member 114 includes a spring, elastic rubber, metal spring, etc., and is used to press the lifting plate 111 upward so that the bottom end of the touch rod 12 is in close contact with the top of the touch switch 112 .

[0053] Refer to the attached Figures 4 to 7 The reminder component 6 includes a control frame 61 fixed to the top of the connection frame 5 and a movable frame 62 fixed to the top of the control frame 61. The control frame 61 and the movable frame 62 are fixedly connected to each other. A sleeve 63 is fixedly connected to one side of the control frame 61, and a camera 64 for photographing the blind spot of the turning is fixedly connected to the inside of the sleeve 63. An opening is provided on the front of the movable frame 62, and a display screen 65 for displaying data of the blind spot and the turning situation is provided inside the movable frame 62. A speaker is installed on the front of the control frame 61, and the display screen 65 extends to the outside of the movable frame 62 through the opening. A protective member 66 for shrinking the display screen 65 and closing the opening is provided between the inside of the control frame 61 and the movable frame 62;

[0054] The camera 64 is used to record the trajectory of the vehicle so that the driver can timely understand the blind spot information when turning, thereby improving the reminder effect. The display screen 65 is used to display the blind spot field of view and the vehicle's driving information. The speaker is used to broadcast the blind spot field of view and the vehicle's driving information, thereby improving the diversity of turning reminders. The protective member 66 is used to protect the information display screen 65, thereby improving the service life of the display screen 65.

[0055] Embodiment 2: Based on embodiment 1, the difference is that;

[0056] Refer to the attached Figures 5 to 7The protective member 66 includes a control panel 661 slidably connected to the top of the inner wall of the movable frame 62, and the display screen 65 is fixedly installed on the front of the control panel 661, and a U-shaped block 662 is fixedly connected to the back of the control panel 661, and one side of the inner wall of the U-shaped block 662 is set as an inclined surface. The inside of the control frame 61 is fixedly connected to an electric telescopic rod 663 through a bracket, and the telescopic end of the electric telescopic rod 663 is fixedly connected to an inclined block 664, the top of the inclined block 664 extends to the inside of the U-shaped block 662, and the inclined surface of the inclined block 664 contacts the inclined surface of the inside of the U-shaped block 662, and an extrusion spring 665 is fixedly connected between the U-shaped block 662 and the inner wall of the movable frame 62;

[0057] An inclined surface is provided on one side of the inner wall of the U-shaped block 662, and the inclined surface contacts the inclined surface of the inclined block 664, so that when the inclined block 664 moves upward, the inclined surface can squeeze the U-shaped block 662, so that the U-shaped block 662 moves horizontally;

[0058] The electric telescopic rod 663 is connected to an external power source and a control switch, and is used to drive the tilting block 664 to move up and down. The up and down movement of the tilting block 664 can squeeze the U-shaped block 662 through the tilting surface, so that the U-shaped block 662 can shrink, and then drive the control panel 661 and the display screen 65 to shrink;

[0059] The elastic force of the squeezing spring 665 can squeeze the U-shaped block 662 to expand the U-shaped block 662, and then the display screen 65 can be driven by the control board 661 to expand through the opening position, thereby improving the display effect of the display screen 65;

[0060] Hidden grooves are provided on both sides of the opening, and baffles 666 for shielding the opening are slidably connected to both sides of the hidden grooves, and inclined connecting frames 667 are hinged on the backs of the two baffles 666. One end of the two connecting frames 667 is hinged to the two sides of the U-shaped block 662 through a bracket, and two sliding grooves for the connecting frames 667 to penetrate and slide are provided between the hidden groove and the inside of the movable frame 62;

[0061] By opening the hidden groove, the hidden installation of the two baffles 666 is facilitated, and the forward and backward movement of the U-shaped block 662 can drive the two connecting frames 667 to move in a fan shape, and the fan-shaped movement of the two connecting frames 667 can make the two baffles 666 move relative to or apart from each other. The relative movement of the two baffles 666 can block the opening, thereby improving the protection effect of the display screen 65, effectively linking the storage of the display screen 65 and the shielding of the opening, without the need to set up a separate electric drive source for driving, thereby improving the orderliness of the protection of the display screen 65.

[0062] Embodiment 3: Based on embodiment 1, the difference is that;

[0063] Refer to the attached Figure 3 and Figures 8 to 10 The locking assembly 10 includes a plurality of moving blocks 101 slidably connected to the bottom of the inner wall of the column rod 4, the tops of the plurality of moving blocks 101 are fixedly connected to guide rods 102, the outer surfaces of the plurality of guide rods 102 are fixedly connected to locking blocks 103, one side of the plurality of locking blocks 103 extends to the outside of the column rod 4, and the plurality of locking blocks 103 are arranged in a circular array, and a driving member for extending and driving the plurality of locking blocks 103 is arranged inside the column rod 4;

[0064] The drive member is arranged to drive the locking block 103 to contract through a plurality of guide rods 102, thereby facilitating the loss of the clamping of the limit plate 7, thereby facilitating the upward movement of the limit plate 7 and realizing the replacement of the limit rod 9. On the contrary, after the limit rod 9 is inserted into the two sets of locking holes 8 at the corresponding positions, the limit plate 7 can be locked after the downward movement through the arrangement of the locking block 103, thereby ensuring the stability of the plurality of limit rods 9 after installation.

[0065] The tops of several locking blocks 103 are all set as inclined surfaces, so that by applying a squeezing force downward to the limit plate 7, the limit plate 7 can be moved to the bottom of the locking block 103. The limit plate 7 can be locked by several locking blocks 103, thereby improving the convenience of locking the limit plate 7.

[0066] The driving member includes a circular plate 104 rotatably connected to the outer surface of the column rod 4, and a plurality of inclined guide grooves 105 are opened inside the circular plate 104, and the top ends of the plurality of guide rods 102 extend to the inside of the plurality of guide grooves 105 respectively, and a rotating shaft 106 is fixedly connected to the top of the circular plate 104, and the top end of the rotating shaft 106 is rotatably connected to the top of the inner wall of the column rod 4, and the outer surface of the rotating shaft 106 is fixedly connected to a connecting plate 107 and a gear 108 in sequence from top to bottom, and a torsion spring 109 is fixedly connected between the top of the connecting plate 107 and the top of the inner wall of the column rod 4, and the interior of the column rod 4 is slidably connected to a tooth plate 1010 meshing with the outer surface of the gear 108 through a sliding frame, and a driving frame 1011 is fixedly connected to the tooth plate 1010, and one side of the driving frame 1011 extends to the outside of the column rod 4;

[0067] By manually pulling the drive frame 1011 laterally, the toothed plate 1010 can be driven to move laterally, and then the gear 108 meshing therewith can be driven to rotate. The rotation of the gear 108 can drive the circular plate 104 to rotate. The rotation of the circular plate 104 can change the positions of the guide grooves 105, so that the guide rods 102 can be retracted inside the guide grooves 105, and then the locking blocks 103 at the corresponding positions can be retracted, so that the locking blocks 103 lose the locking of the limit plate 7, which makes it easier for the staff to install the limit rod 9.

[0068] On the contrary, by manually losing the pull on the drive frame 1011, the torsion spring 109 can drive the connecting plate 107 and the circular plate 104 that have lost the rotational force to rotate in the opposite direction, thereby performing a reset operation. Through the reverse rotation of the circular plate 104, a plurality of locking blocks 103 can be driven to expand through a plurality of guide rods 102, thereby locking the limit plate 7. The limit plate 7 has a good extension function, and a plurality of locking blocks 103 can be driven to retract at the same time, thereby improving the convenience for the staff to install the limit rod 9 and replace the damaged limit rod 9.
