[0001] This invention belongs to the field of vehicle technology, and in particular relates to a side road sign installation tool and installation method. Background Technology

[0002] In the bus manufacturing industry, due to the lack of dedicated installation tools, one person is needed to observe from outside the vehicle to ensure the road signs are aligned with the black edge of the glass, and to direct the personnel inside the vehicle to adjust and install them. The entire assembly process is time-consuming and labor-intensive. Furthermore, due to differences in individual conditions and inspection standards, such as observation position, direction, and eyesight, there are variations in the consistency of the final product. Summary of the Invention

[0003] To address the technical problems mentioned in the background section, this invention provides a side road sign installation fixture and method. The position of the side road sign is predicted by the potential difference output by the photosensitive battery and displayed on a monitor, thereby quickly determining the direction and distance that the side road sign needs to be adjusted, improving the efficiency of aligning the side road sign with the black edge of the glass, and increasing assembly efficiency.

[0004] To achieve the above objectives, the specific technical solution of the side road sign installation fixture and installation method of the present invention is as follows:

[0005] A side road sign installation fixture includes a telescopic rod with a pair of support arms hinged to each end. L-shaped handles are rotatably connected to the ends of the support arms and fixed at the four corners of the side road sign. The fixture also includes light receivers mounted on the handles and light emitters mounted on the exterior of the vehicle body. The light emitters are aligned with the center of the light-transmitting glass of the bus frame. By adjusting the position of the side road sign, the electrical signals output by each light receiver are made equal, thereby aligning the side road sign with the light-transmitting glass.

[0006] Furthermore, the telescopic rod includes an outer tube and an inner tube that are nested together. One end of the outer tube is provided with a limiting ring, and the end of the inner tube is provided with a limiting block. An elastic element is fitted on the inner tube. The free end of the inner tube is inserted into the outer tube from the side away from the limiting ring and passes through the limiting ring. The free end of the outer tube is tightened with an end cap.

[0007] Furthermore, the elastic element is a spring, and the two ends of the spring are connected to the limiting ring and the limiting block, respectively.

[0008] Furthermore, one pair of support arms is hinged to the free end of the inner tube, and another pair of support arms is hinged to the end of the end cap.

[0009] Furthermore, each pair of support arms has a connection notch at its end, and the connection notches are positioned opposite each other. The free end or end cap of the inner tube has a connecting plate, which is placed between the two connection notches. The support arm is connected to the inner tube or end cap by locking bolts.

[0010] Furthermore, it also includes a universal joint, one end of which is screwed onto the end of the support arm, and the other end of which is fixed to the corner of the hook.

[0011] Furthermore, a protective layer is provided on the inner wall of the handle. The protective layer is made of protective cotton, rubber or plastic and is adhered to the inner wall of the handle.

[0012] Furthermore, a controller is installed inside the telescopic pole, and each optical receiver is electrically connected to the controller via a wire. A display is installed on the outer wall of the telescopic pole, and the display is electrically connected to the controller. The controller displays the electrical signals received from the optical receivers on the display.

[0013] Furthermore, the light receiver is a photosensitive solar panel, with the photosensitive surface of the solar panel facing away from the direction of the hand, and the light emitter is a diffused light source or a halogen lamp.

[0014] A method for installing a side road sign mainly includes the following steps:

[0015] Light emitter installation steps: Install the light emitter outside the vehicle, with the center line of the transparent glass passing through the light emitter;

[0016] Installation steps for the installation tool: Fix the handles to the four corners of the side road sign, ensuring that the telescopic rod is in the horizontal center position of the side road sign after fixing;

[0017] Side road sign position adjustment steps: Turn on the light transmitter, obtain the electrical signal values ​​output by each light receiver, and adjust the position of the side road sign until the output electrical signal values ​​of each light receiver are equal.

[0018] The side road sign installation fixture and installation method of the present invention have the following advantages:

[0019] The side road sign installation fixture of this invention predicts the position of the side road sign by using the potential difference output by the photosensitive battery and displays it on the display, thereby quickly determining the direction and distance that the side road sign needs to be adjusted, improving the efficiency of aligning the side road sign with the black edge of the glass, and reducing the number of assembly personnel; it adopts a telescopic rod with self-locking, and the fixture is pre-installed by the tensioning force of the telescopic rod and the four hooks hanging at the four corners of the side road sign, which improves the efficiency of fixture pre-installation and facilitates disassembly and assembly.

[0027] To better understand the purpose, structure, and function of this invention, the following detailed description, in conjunction with the accompanying drawings, provides an example of a side road sign installation fixture and installation method.

[0028] like Figures 1-2 As shown, this application provides a side road sign installation fixture, including a telescopic rod 1, with a pair of support arms 2 hinged to each end of the telescopic rod 1. L-shaped handles 6 are rotatably connected to the ends of the support arms 2, and the handles 6 are fixed at the four corners of the side road sign 8. The fixture also includes light receivers mounted on the handles 6 and light emitters mounted on the exterior of the vehicle body. The light emitters are aligned with the center of the light-transmitting glass of the bus frame. By adjusting the position of the side road sign 8, the electrical signals output by each light receiver are made equal, achieving alignment between the side road sign 8 and the light-transmitting glass. The side road sign 8 is then fixed to the bus frame using fasteners. The position of the side road sign 8 is predicted by the potential difference output by the photosensitive battery and displayed on the display 4, thereby quickly determining the direction and distance that the side road sign 8 needs to be adjusted, improving the efficiency of aligning the side road sign 8 with the black edge of the glass, and reducing the number of assembly personnel.

[0029] like Figures 3-4 As shown, the telescopic rod 1 includes an outer tube 11 and an inner tube 12 that are sleeved together. One end of the outer tube 11 is provided with a limiting ring 111, and the end of the inner tube 12 is provided with a limiting block 121. An elastic element 7 is sleeved on the inner tube 12. The free end of the inner tube 12 is inserted into the outer tube 11 from the side away from the limiting ring 111 and passes through the limiting ring 111. The free end of the outer tube 11 is tightened with an end cap 13.

[0030] The elastic element 7 can be a spring or an elastic sleeve made of elastic materials such as rubber, plastic, or metal. Preferably, the elastic element 7 is a spring, and the two ends of the spring are connected to the limiting ring 111 and the limiting block 121, respectively.

[0031] One pair of support arms 2 are hinged to the free end of the inner tube 12, and another pair of support arms 2 are hinged to the end of the end cap 13. For example... Figure 4As shown, each pair of support arms 2 has a connection notch at its end, and the connection notches are arranged opposite each other. The free end of the inner tube 12 or the end cap 13 is provided with a connecting plate. The connecting plate is placed between the two connection notches. The support arm 2 is connected to the inner tube 12 or the end cap 13 by locking bolts to realize the hinge connection between the support arm 2 and the telescopic rod 1.

[0032] To enable the rotational connection between the support and the handle 6, a universal joint 5 is also included. One end of the universal joint 5 is screwed onto the end of the support arm 2, and the other end of the universal joint 5 is fixed at the corner of the handle 6.

[0033] The inner wall of the handle 6 is provided with a protective layer 61, which can be made of elastic materials such as protective cotton, rubber, or plastic. The protective layer 61 is adhered to the inner wall of the handle 6. By setting the protective layer 61, the handle 6 is prevented from scratching the side road sign 8.

[0034] To facilitate real-time observation of the electrical signals of each optical receiver, a controller is installed inside the telescopic rod 1. Each optical receiver is electrically connected to the controller via wires. A display 4 is installed on the outer wall of the telescopic rod 1. The display 4 is electrically connected to the controller. The controller displays the received electrical signals of the optical receivers on the display 4, which allows users to observe and adjust in real time during use, improves the alignment accuracy of the side road sign 8 and the black edge of the glass, and enhances assembly efficiency.

[0035] To enable the optical receiver to connect to the controller, components such as the universal joint 5, support arm 2, and limit block 121 are provided with through holes for wires to pass through.

[0036] like Figure 1 As shown, the light receiver is a photosensitive solar panel, with the photosensitive surface of the solar panel away from the direction of the hanging handle 6. The light emitter is a diffused light source, a halogen lamp, etc. To ensure that the position of the light receiver has no impact on the detection results, after the installation fixture is fixed to the side road sign 8, the distance from each light receiver to the center of the side road sign 8 is equal, that is, each light receiver is centrally symmetrically distributed with respect to the center of the side road sign 8.

[0037] In addition, optical receivers can also be photoresistors, PIN photodiodes, and avalanche diodes.

[0038] like Figure 5 As shown, the side road sign 8 includes a square body 81. Mounting plates 82 are respectively provided on the two side walls of the body 81. Mounting plates 82 are provided with mounting holes. After adjustment, the mounting holes are aligned with the fixing holes on the frame. The side road sign 8 is fixed to the frame by fasteners, thus completing the assembly of the side road sign 8.

[0039] This application also provides a method for installing a side road sign 8, which mainly includes the following steps:

[0040] Light emitter installation steps: Install the light emitter outside the vehicle, with the center line of the transparent glass passing through the light emitter;

[0041] Installation steps for the installation tool: Fix the hook 6 to the four corners of the side road sign 8 respectively, and ensure that the telescopic rod 1 is in the horizontal center position of the side road sign 8 after fixing;

[0042] Side road sign position adjustment steps: Turn on the light transmitter, obtain the electrical signal values ​​output by each light receiver, adjust the position of the side road sign 8 until the output electrical signal values ​​of each light receiver are equal, thus completing the alignment of the side road sign 8 with the light-transmitting glass, fix the side road sign 8 to the frame with fasteners, disassemble and install the fixtures, and complete the installation of the side road sign 8.

[0043] The side road sign installation fixture predicts the position of the side road sign 8 by using the potential difference output by the photosensitive battery and displays it on the display 4, thereby quickly determining the direction and distance that the side road sign 8 needs to be adjusted, improving the efficiency of aligning the side road sign 8 with the black edge of the glass, and reducing the number of assembly personnel; it adopts a telescopic rod 1 with self-locking, and uses the tensioning force of the telescopic rod 1 and the four hooks 6 hanging at the four corners of the side road sign 8 to form a tension form for pre-installation of the fixture, improving the efficiency of fixture pre-installation and facilitating disassembly and assembly.
