Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this utility model is to provide a carport sunshade device, a carport, and a tricycle to solve the problems existing in the prior art. It can be freely extended and retracted, is easy to operate, and can effectively resist wind and prevent falling off.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 Combination Figures 1 to 2 This embodiment provides a carport sunshade device, including: a winding mechanism 2, a sunshade cloth 3, and a locking component; the winding mechanism 2 is disposed on the top of the carport 1 and is used to realize the winding and unfolding of the sunshade cloth 3; the sunshade cloth 3 has a first end fixedly connected to the winding mechanism 2 and a second end that can be freely pulled out; the locking component is used to lock the sunshade cloth 3 when it is unfolded.

[0023] The carport sunshade device provided in this embodiment has a simple structure. When sunshade is needed, the sunshade cloth can be freely extended and locked. When not needed, it can be rolled up by the retracting mechanism. The operation is simple, and users can easily unfold and retract the sunshade cloth. After unfolding, it can be effectively fixed by the locking component, which enhances the stability and reliability of the device under the action of external forces such as wind.

[0024] In some embodiments, the winding mechanism 2 includes a spool and a torsion spring; the spool is rotatably arranged about its own axis, and the first end of the sunshade cloth 3 is fixedly connected to the outer circumferential surface of the spool; the torsion spring is coaxially sleeved on the spool near the end, with the inner end of the torsion spring fixed to the spool and the outer end used to fix it to an external fastener; the torsion spring is configured to accumulate torque when the sunshade cloth 3 is pulled out and to provide power for the automatic rewinding of the sunshade cloth; the elastic potential energy of the torsion spring is used to realize the automatic and rapid winding of the sunshade cloth 3, eliminating manual operation and significantly improving ease of use; in addition, the design of the torsion spring built into the spool is highly integrated, saving installation space, making the overall structure more compact, while reducing external interference and improving the reliability and lifespan of the mechanism.

[0025] In some embodiments, the locking assembly includes a positioning rod 4 and several pairs of positioning slots 5; the positioning rod 4 is fixedly connected to the second end of the sunshade cloth 3; the positioning slots 5 are symmetrically arranged on both sides of the windshield 6 of the carport 1; the positioning rod 4 can be detachably engaged in any pair of positioning slots 5.

[0026] In this embodiment, the locking component provides excellent wind resistance stability by detachably engaging the positioning rod 4 with multiple pairs of symmetrically arranged positioning slots 5. Its simple structure and convenient operation significantly improve the applicability, safety and user experience of the device.

[0027] Preferably, the positioning slots 5 are in multiple pairs, arranged vertically at intervals. Users can insert the positioning rod 4 into slots of different heights according to the angle of sunlight and shading needs, thereby flexibly controlling the drooping degree and shading area of ​​the sunshade cloth 3 to achieve the best balance between shading effect and forward visibility. This design not only significantly improves the device's environmental adaptability and user experience, but also enhances wind resistance and safety by reducing the windward area when selecting higher slots in windy weather. The entire adjustment mechanism is achieved through a simple mechanical structure, requiring no complex components, and has significant advantages in high reliability and low cost.

[0028] In some embodiments, one end of the positioning slot 5 is fixed to the edge of the windshield 6 of the carport 1, and the other end extends away from the windshield 6 and is provided with a downward hook structure.

[0029] In this embodiment, the positioning slot 5, by fixing one end to the edge of the windshield 6 and extending the other end outward with a downward-facing hook structure, significantly improves the practicality and reliability of the device. The downward-facing hook effectively locks the positioning rod 4, preventing it from accidentally coming off due to vibration or strong winds, greatly enhancing its wind resistance and anti-detachment safety; the extended section naturally forms a guide entrance, making the insertion of the positioning rod 4 simpler and more intuitive.

[0030] In some embodiments, the sunshade cloth 3 is made of sunshade and heat insulation material, which can effectively shade and insulate the sun, directly reduce the temperature rise inside the carport 1, and greatly improve the comfort of the driver and passengers; at the same time, blocking ultraviolet rays can also effectively slow down the aging rate of the interior facilities (such as seats, dashboard, etc.) of the carport 1, prevent them from fading and deteriorating, and extend their service life.

[0031] In some embodiments, the positioning rod 4 and the second end of the sunshade cloth 3 are detachably connected. It is understood that the positioning rod in this application can be a structure similar to a plastic or metal clip, clamping the edge of the sunshade cloth and the positioning rod together. The clip typically has anti-slip teeth or soft rubber pads inside to increase friction. This detachable connection design achieves functional modularity by separating the positioning rod 4 from the sunshade cloth 3, bringing multiple practical advantages: First, it greatly improves maintenance convenience; if either the sunshade cloth 3 or the positioning rod 4 is damaged, it can be replaced independently, significantly reducing subsequent maintenance costs. Second, it gives the device excellent functional expandability; by replacing the positioning rod 4 with different lengths, materials, or shapes, it can flexibly adapt to various vehicle models or different models of sunshade cloth 3, improving the product's versatility and market adaptability.

[0032] In some embodiments, the winding mechanism 2 is provided with a protective cover, and the protective cover has a slit for the sunshade cloth 3 to pass through; the protective cover is connected to the top of the carport 1.

[0033] In this embodiment, a protective cover is provided outside the winding mechanism 2, and a specific slit is opened for the sunshade cloth 3 to pass through. Its core function is to provide crucial sealing protection for the precision winding mechanism 2, which can effectively isolate dust, moisture, rainwater and foreign objects from intrusion, and greatly improve the durability and reliability of the mechanism. The slit structure also plays a precise guiding role in the winding and unwinding of the sunshade cloth 3, preventing it from deviating or wearing out. In addition, the protective cover completely isolates personnel from contact with internal moving parts, eliminates the risk of pinching injury, and significantly enhances safety.
