Detailed Implementation
[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0021] Depend on Figures 1 to 5 The device includes an aluminum alloy rod 1, a bracket 2 fixedly connected to the upper end of the aluminum alloy rod 1, a hinge seat 3 fixedly connected to the upper end of the bracket 2, an angle-adjustable hinge frame 4 above the hinge seat 3, a hinge rod 5 fixedly connected to the lower side of the hinge frame 4, the hinge rod 5 being hinged to the hinge seat 3, an end face ratchet 6 fixedly connected to the left side of the hinge seat 3, a meshing ratchet 7 on the hinge rod 5 that can move left and right and can mesh with the end face ratchet 6, a connecting frame 8 fixedly connected to the upper end of the hinge frame 4, and a screen 9 fixedly connected to the upper end of the connecting frame 8.
[0022] like Figures 1 to 5 As shown, aluminum alloy rod 1 is set as the core support component, providing a rigid foundation for the overall structure and ensuring the stability of screen 9 during robot movement. Bracket 2, hinge seat 3, hinge frame 4, and hinge rod 5 are set up to connect aluminum alloy rod 1 and hinge seat 3 via bracket 2, transmitting support force. Hinge seat 3 serves as a rotating base, and the rotation of hinge frame 4 enables multi-directional adjustment of the screen 9's pitch angle to meet different viewing angle requirements. End face ratchet 6 and meshing ratchet 7 provide a pre-fixed pitch angle function for screen 9, facilitating angle adjustment during maintenance without secondary fixing, achieving rapid adjustment. Connecting frame 8 serves as the installation platform for screen 9, facilitating screen 9 fixation. This utility model, through the rigid support system of aluminum alloy rod 1, bracket 2, and hinge seat 3, combined with a ratchet-locked hinge mechanism, achieves multi-directional flexible adjustment and stable fixation of the food delivery robot screen 9.
[0023] The hinge frame 4 has multiple positioning holes 10 distributed along its circumference. The left and right sides of the hinge seat 3 are respectively slidably connected with L-shaped positioning pins 11 that can be inserted into the corresponding side positioning holes 10. The two positioning pins 11 can move relative to each other or away from each other.
[0024] like Figures 4 to 5 As shown, the positioning hole 10 and positioning pin 11 allow the screen 9 to rotate horizontally at multiple angles and lock precisely. The symmetrical sliding design of the positioning pin 11 ensures simultaneous locking in both directions, preventing the screen 9 from rotating or shifting due to sudden stops or collisions with the robot.
[0025] The hinge seat 3 is provided with a movable plate 12 that can move back and forth. The movable plate 12 has two left-right symmetrical inclined grooves 13. One side of the positioning pin 11 is located in the inclined groove 13 on its corresponding side. A movable block is fixedly connected to the upper end of the movable plate 12.
[0026] like Figures 4 to 5As shown, the movable plate 12 inside the hinge base 3 drives the synchronous movement of the positioning pins 11 on both sides by moving back and forth. The tilting groove 13 converts the longitudinal displacement of the movable plate 12 into the lateral displacement of the positioning pins 11, realizing mechanical linkage. This design simplifies operation, requiring only a single-direction push of the movable plate 12 to control the locking / unlocking of the two pins, improving adjustment efficiency. The symmetrical tilting groove 13 ensures the synchronous movement of the two positioning pins 11, avoiding screen 9 shaking or deflection due to insecure locking on one side.
[0027] A lead screw 14 is rotatably connected to the hinge seat 3. The lead screw 14 is threadedly connected to the moving block. A rotary knob is fixedly connected to the rear end of the lead screw 14.
[0028] like Figures 4 to 5 As shown, a lead screw 14 is installed on the hinge seat 3 and forms a threaded connection with the moving block, so that the forward and backward movement of the moving block can be precisely controlled when the lead screw 14 is rotated. This transmission method has a self-locking characteristic, which can prevent the positioning pin 11 from accidentally dislodging from the positioning hole 10 due to vibration or external force, thereby improving the locking reliability. The knob is set and its external design facilitates quick operation without the need for additional tools, meeting the convenience requirements for maintenance or daily adjustment.
[0029] A return spring is fixedly connected to the right end of the engagement ratchet 7, located between the engagement ratchet 7 and the hinge rod 5. The return spring is located inside the hinge rod 5. A push rod 15 is fixedly connected to the left side of the engagement ratchet 7. The push rod 15 is slidably connected to the hinge rod 5. A button is fixedly connected to the left end of the push rod 15.
[0030] like Figures 4 to 5 As shown, the engagement ratchet 7 is elastically connected to the hinge rod 5 via a return spring. The built-in spring design saves space and protects the spring from external damage. The return spring provides automatic rebound force, ensuring that the engagement ratchet 7 remains in constant engagement with the end face ratchet 6 when no external force is applied, achieving instant locking of the screen 9's tilt angle and preventing angle deviation due to gravity or vibration. The push rod 15 and the hinge rod 5 slide together to form a linear guide structure, ensuring stable lateral movement trajectory of the engagement ratchet 7 and preventing uneven wear. The external button design allows for one-handed operation. When pressed, the push rod 15 pushes the engagement ratchet 7 away from the end face ratchet 6, unlocking it and facilitating quick adjustment of the screen 9's angle. After releasing, the return spring automatically resets, restoring the engagement state, making operation intuitive and efficient.
[0031] The aluminum alloy rod 1 has a wire groove inside, an inlet groove 16 on the lower side of the aluminum alloy rod 1, and an outlet groove 17 on the upper end of the aluminum alloy rod 1.
[0032] like Figures 2 to 3As shown, an aluminum alloy rod 1 is set as the core support structure. The internal cable tray can effectively store power cables, signal cables and other cables, avoid the cables from being exposed, improve the overall aesthetics, and reduce the risk of damage caused by cable tangling or external pulling. The cable inlet tray 16 and cable outlet tray 17 are set to facilitate cable lead-in.
[0033] The outer wall of the aluminum alloy rod 1 is provided with a protective shell 18.
[0034] like Figures 1 to 2 As shown, the protective shell 18 is provided to prevent the aluminum alloy rod 1 from being damaged by external collisions, friction or environmental factors, and to extend the service life of the aluminum alloy rod 1. The protective shell 18 can be made of wear-resistant, corrosion-resistant or insulating materials to further enhance the protective capability of the aluminum alloy rod 1, adapt to different usage environments, and improve the overall aesthetics.
[0035] When using this utility model, the aluminum alloy rod 1 is connected to the mobile device of the food delivery robot. Then, the button on the hinge frame 4 is pressed to push the meshing ratchet 7 to disengage from the end face ratchet 6, thus unlocking the device. After manually adjusting the screen 9 to the desired pitch angle, the button is released, and the reset spring pushes the meshing ratchet 7 to re-engage, thereby fixing the angle.
[0036] Rotate the knob behind the hinge seat 3 to drive the lead screw 14 to move the moving plate 12 backward, so that the positioning pin 11 is inserted into the corresponding positioning hole 10, and the screen 9 angle is locked. When the screen 9 moves or the robot stops suddenly, the double locking of the ratchet engagement mechanism and the positioning pin 11 can effectively suppress the shaking. The rigid aluminum alloy rod 1 and the protective shell 18 absorb external impacts and prevent the screen 9 from shifting.
[0037] The cable is introduced into the internal cable channel through the cable inlet slot 16 at the bottom of the aluminum alloy rod 1, and connected to the screen 9 from the top cable outlet slot 17, reducing the risk of tangling or pulling caused by exposed cables.
[0038] The bracket 2 components can be unlocked by using knobs and buttons without tools. The protective shell 18 can be removed and installed separately to facilitate inspection of the aluminum alloy rod 1 or the cable status in the cable tray.
[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
