Description

[Technical Field]

[0001] The present application relates to the technical field of sunshades for automobiles, and more particularly to an umbrella pole for an inner sunshade for automobiles. [Background technology]

[0002] When a car is parked outdoors in the summer, strong sunlight penetrates the windshield and shines directly into the interior of the car, causing the temperature inside the car to rise rapidly, affecting ride comfort and increasing air conditioning energy consumption. This not only accelerates the deterioration, cracking, and fading of interior components such as instrument panels and seats, but also shortens their lifespan. Car inner sunshades can effectively solve these problems and are a necessary solution to the heat of the summer sun.

[0003] Chinese utility model application number 202223494887.3 provides a central rod for a car sunshade, which comprises a central rod body, an upper link, a lower link, and a bending member, the bending member being located in the middle of the central rod body, the central rod body being bendable along the bending member, the upper link being fixedly connected to the upper end of the central rod body, and the lower link being covered by the outside of the central rod body and being movable up and down along the central rod body. Because the middle of the central rod is bendable, the umbrella handle can be supported on the dashboard when the car sunshade is in use, making the installation more stable.

[0004] In the above utility model, the umbrella handle is supported on the dashboard by a folding member, thereby achieving stable installation. The folding member in this utility model comes into contact with the dashboard of the vehicle during use. A folding member made of a soft material lacks structural strength and fatigue resistance, and suffers from a relatively high rate of damage when constantly bent and at high temperatures. A folding member made of a hard material can ensure structural strength and durability, but the contact area with the dashboard is prone to indentations, wear, and scratches on the vehicle body when the vehicle vibrates or is subjected to force during installation.

[0015] In order to clarify the implementation purpose, technical solution and advantages of the present invention, the present invention will be described in more detail below with reference to the drawings and the following embodiments, so that the public can better understand how to implement the present invention. The specific implementation means of the present invention are as follows:

[0016] As shown in FIG. 1-4, the umbrella pole for an inner sunshade for a car comprises an umbrella pole body 1, the umbrella pole body 1 including an upper umbrella pole 11, a connecting member 12, and a lower umbrella pole 13, the lower umbrella pole 13 being connected to the connecting member 12 by a hinge connection structure, the connecting member 12 being rotatably connected to the upper umbrella pole 11, an upper roller 2 fixed to the upper end of the upper umbrella pole 11, a lower roller 3 provided below the upper roller 2, the lower roller 3 being slidably fitted to the outside of the umbrella pole body 1, a first limit groove 4 opened at the lower end of the lower roller 3, a protective sleeve 5 fitted to the outside of the lower roller 3, and a limit structure that fits into the first limit groove 4 provided on the protective sleeve 5. The protective sleeve 5 has a guide groove 6, and is provided with an upper umbrella pole 11, a connecting member 12, a lower umbrella pole 13, and a protective sleeve 5. During use, the protective sleeve 5 is moved to the connection between the umbrella pole and the connecting member 12, and the lower umbrella pole 13 is rotated so as to bend it at a perpendicular angle to the upper umbrella pole 11, and the end of the lower umbrella pole 13 is supported on the dashboard of the automobile. During the entire process, the connection between the lower umbrella pole 13 and the connecting member 12 remains completely within the protective sleeve 5, which prevents contact friction between the top end of the lower umbrella pole 13 and the bottom end of the connecting member 12 and the car body when the lower umbrella pole 13 is bent, thereby preventing wear and tear on the car body surface and achieving effective protection of the car body surface.

[0017] The protective sleeve 5 has a hollow structure, and the limit structure is two limit rings 7 fixed to both the upper and lower ends of the inner wall of the protective sleeve 5. The outer end surfaces of the two limit rings 7 are flush with the upper and lower end surfaces of the protective sleeve 5, respectively. The limit rings 7 are installed mainly to prevent the protective sleeve 5 from detaching from the runner 3. When the lower end surface of the upper limit ring 7 on the inner wall of the protective sleeve 5 contacts the lower wall of the limit groove (in use), the protective sleeve 5 completely covers the connection between the lower umbrella rod 13 and the connecting member 12, preventing wear and tear on the surface of the dashboard. When the upper end surface of the lower limit ring 7 on the inner wall of the protective sleeve 5 contacts the upper wall of the limit groove (not in use), the protective sleeve 5 completely detaches from the connection between the lower umbrella rod 13 and the connecting member 12, making it easy to attach and detach.

[0018] An attachment groove 8 is formed in the center of the connecting member 12, a pin shaft 9 is fixedly installed in the attachment groove 8, and the lower umbrella rod 13 is hingedly connected to the connecting member 12 by the pin shaft 9.

[0019] Furthermore, a protrusion 10 is fixed to the lower end surface of the connecting member 12, and a groove 14 corresponding to the protrusion 10 is provided at the upper end of the lower rod 13. The groove 14 and the protrusion 10 are spaced apart from each other, and when the protrusion 10 is positioned within the groove 14, the lower rod 13 and the upper rod 11 are aligned, effectively preventing the rod body 1 from bending when not in use. After the protrusion 10 is released from the groove 14, the lower rod 13 and the upper rod 11 are aligned vertically.

[0020] It should be mentioned that the protective sleeve 5 is made of rubber material.

[0021] In addition, a second limit groove 15 is formed on the outer surface of the runner 3, an elastic pressure plate 16 is installed outside the second limit groove 15, and the lower end of the elastic pressure plate 16 is fixedly connected to the runner 3. The upper umbrella rod 11 has a hollow structure, and an elastic member 17 is installed inside the upper umbrella rod 11. A first mounting hole 18 and a second mounting hole 19 are formed on the outer surface of the upper umbrella rod 11. The elastic member 17 includes a U-shaped plate, the upper end of which on the left side is engaged in the first mounting hole 18 and the upper end of the right side of which passes through the second mounting hole 19 and protrudes outside the upper umbrella rod 11. A baffle plate 20 is fixed to one side of the upper end surface of the right side of the U-shaped plate. The installation of this structure is mainly for controlling the opening and closing of the sunshade.

[0022] When in use, the lower roller 3 is moved upward along the lower umbrella rod 13 to the upper umbrella rod 11. During this process, the inner wall of the lower roller 3 pushes the part protruding from the U-shaped plate into the second mounting hole 19. The upper right end of the U-shaped plate is pushed outward by its own elastic restoring force until the second limit groove 15 on the outer surface of the lower roller 3 is flush with the second mounting hole 19. The upper right end of the U-shaped plate then protrudes through the second mounting hole 19 and the second limit groove 15 in sequence, limiting the position of the lower roller 3 and keeping the sunshade open and stable. , presses the elastic pressure plate 16, which pushes the U-shaped plate into the second mounting hole 19, removing the lower roller 3 from the limit of the U-shaped plate. Continuing to press the elastic pressure plate 16, the lower roller 3 moves downward along the upper umbrella rod 11, and the sunshade begins to fit and close. During this process, when the upper end surface of the lower roller 3 moves below the second mounting hole 19, the U-shaped plate will, based on its own characteristics, have its upper right end protrude outside the second mounting hole 19 until the baffle plate 20 contacts the inner wall of the upper umbrella rod 11.

[0023] The working principle and process of this invention are as follows:

[0024] First, open the sunshade, move the lower roller 3 onto the upper rod 11, and move the protective sleeve 5 downward along the first limit groove 4 until the lower end surface of the upper limit ring 7 on the inner wall of the protective sleeve 5 contacts the lower wall of the first limit groove 4. At this time, the protective sleeve 5 completely covers the connection between the lower rod 13 and the connecting member 12, and grasps and rotates the lower rod 13. The lower rod 13 and the connecting member 12 rotate together around the axis of the upper rod 11 until the top end of the lower rod 13 is flush with the guide engagement groove 6 on the protective sleeve 5 in the circumferential direction. Then, the lower rod 13 is bent and rotates around the pin shaft 9 until the top end of the lower rod 13 is engaged in the guide engagement groove 6 and the end of the lower rod 13 is supported on the automobile dashboard.
