AI Technical Summary
The expansion size of existing vehicle-mounted awnings is limited, resulting in a small shade area and low space utilization.
A telescopic section is added to the forearm of the existing curved arm awning, and the expansion and contraction movement of the inner and outer tubes is driven by the gas spring to achieve the expansion and contraction of the two arms and increase the sunshade area.
The expansion and contraction movement of the inner and outer tubes driven by the gas spring increases the extension size of the awning by 50%, thereby significantly increasing the shading area.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle awning components, in particular to a awning with retractable arms. Background Art
[0002] Existing vehicle awnings typically utilize a curved arm design, resulting in a small extended length and a smaller shaded area. With the commonly used two-section curved arm design, the maximum extended length of the awning is related to the extended length of the arms. Due to size limitations, a typical two-meter-wide awning with two arms can only extend to approximately 1.5 meters, resulting in a relatively small shaded area and low space utilization. Utility Model Content
[0003] The purpose of the utility model is to solve the above problems and provide a sunshade with telescopic arms, which adds a telescopic section to the forearm of the existing curved arm, thereby increasing the sunshade area.
[0004] The technical solution adopted by this utility model is:
[0005] A sunshade with retractable arms is characterized in that it includes an awning body and two arms hinged on the awning body, a front rod is set at the front ends of the two arms, the arms include a front arm and a rear arm connected by a middle hinge, the forearm includes an outer tube and an inner tube, the inner tube is inserted into the outer tube, a gas spring is set in the outer tube, the length of the inner tube corresponds to the telescopic arm of the gas spring, the tail end of the gas spring is fixed on the middle hinge, the telescopic arm of the gas spring is fixed in the inner tube, and the front end of the gas spring is connected to the front rod through a front hinge.
[0006] Furthermore, the middle hinge includes a hinge concave and a hinge convex that are hingedly connected to each other, the hinge concave is arranged at the front end of the rear arm, and the hinge convex is arranged at the tail end of the gas spring.
[0007] Furthermore, a tail plug is provided at the tail of the inner tube, and the tail plug slides in cooperation with the inner wall of the outer tube.
[0008] Furthermore, a decorative cover is fixed to the front end of the outer tube, and the outer wall of the inner tube slides in cooperation with the decorative cover.
[0009] Furthermore, the tarpaulin pulled out from the tarpaulin body is fixed in cooperation with the front rod.
[0010] The beneficial effects of the utility model are:
[0011] Driven by a gas spring, the front arm of the awning can achieve two-stage telescopic movement. Compared with the two-stage arms of ordinary curved arm awnings, the extension size can be increased by 50%, thereby increasing the shade area. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The specific implementation of the sunshade with retractable arms of the utility model is described in detail below with reference to the accompanying drawings.
[0026] See attached Figure 1 、 2 The awning body 1 has two hinged arms 2 that can be bent and opened to form the awning frame. A front bar 3 is provided at the front end of the two arms 2, and a tarpaulin 4 is connected to the front bar to form the awning. The connection can be manually pulled, driven by a machine head, or driven by a motor.
[0027] See attached Figure 3 、 4 The arm 2 includes a forearm 6 and a rear arm 7 connected by a middle hinge 5. The hinge recess 8 of the middle hinge 5 is set at the front end of the rear arm 7. The forearm 6 includes an outer tube 9 and an inner tube 10. The inner tube 10 is inserted into the outer tube 9. A gas spring 11 is set in the outer tube 9. The length of the inner tube 10 corresponds to the telescopic arm 12 of the gas spring 11. The tail end of the gas spring 11 is fixed to the hinge protrusion 13 of the middle hinge 5. The telescopic arm 12 of the gas spring 11 is fixed in the inner tube 10. The front end of the gas spring 11 is connected to the front rod 3 through the front hinge 14.
[0028] The tail of the inner tube 10 is provided with a tail plug 15, which slides in cooperation with the inner wall of the outer tube 9. A decorative cover 16 is fixed to the front end of the outer tube 9, and the outer wall of the inner tube 10 slides in cooperation with the decorative cover 16.
[0029] The following uses a hand-pull drive awning as an example to explain the working process of the awning arm:
[0030] To open the awning, the front and rear arms 7 are extended to form a frame, which then activates the gas spring 11 to extend the inner tube 10 of the front arm 6, extending the frame. The tarpaulin 4 is then pulled out of the awning body 1 and secured to the front pole 3. To close the awning, the tarpaulin 4 is first retracted into the awning body 1. The gas spring 11 then retracts the inner tube 10 of the front arm 6, which is then closed and retracted back into the awning body 1.
[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
