The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] like Figure 1As shown, this application provides a sunshade with a fan, which can be installed on a stroller. The sunshade 230 is provided with a mounting base 231, and the fan 300 is rotatably connected to the mounting base 231 about an axis. The fan 300 has an air outlet and a corresponding airflow direction. The stroller includes a body 100, which can be... Figure 1 The exhibit showcases the structure, or a pushcart. (Attached) Figure 1 For example, the vehicle body 100 includes two oppositely arranged side frames. Each side frame includes a front leg 110 with a front wheel, a rear leg 120 with a rear wheel, and a handlebar 130. The front leg 110 tilts forward from top to bottom, the rear leg 120 tilts backward from top to bottom, and the handlebar 130 tilts backward from bottom to top. To improve the structural strength of the product, there are connecting parts between the two side frames. For example, a front leg connecting rod 111 connects the two front legs 110, a rear leg connecting rod 121 connects the two rear legs 120, and a handlebar connecting rod 131 connects the two handlebars 130. The handlebar connecting rod 131 also serves as a grip, which is used by the operator to hold and push the vehicle body.

[0023] The vehicle body 100 has a seating space 101 for users, including children and pets. The vehicle body 100 includes a seat cushion 210 for supporting a child's bottom and a backrest 220 for supporting the child's back. The seat cushion 210 and backrest 220 are positioned between the two side frames, and the three together form the seating space. Furthermore, the vehicle body 100 also includes armrests 240 positioned between the two side frames.

[0024] The awning 230 can be mounted on the handle 130, or as... Figure 1 As shown, the awning 230 is mounted on the backrest 220 and covers the seating space 101. In actual use: The operator can rotate the fan 300 to ensure optimal airflow direction based on the child's height and sitting posture, for example, directing the airflow towards the user within the seating space 101. Compared to existing technologies, the fan in this application has a wider adjustment angle and more airflow directions, allowing for adjustments to the optimal airflow angle for the child. Furthermore, adjusting the airflow direction does not require adjusting the armrests or other components, enhancing safety. The fan's position near the top of the vehicle body makes it convenient and effortless for the operator to adjust.

[0025] The awning 230 includes a base, multiple arc-shaped support rods 232, and an awning fabric 233. Each support rod 232 has a base at both ends, and the base is connected to a backrest 220 or a handle 130. The awning fabric 233 is arranged between the support rods 232 to form a sunshade surface. The awning fabric 233 is made of fabric and has mounting holes at preset positions. Mounting seats 231 are fixedly connected to the mounting holes. The mounting seats 231 have through holes serving as air inlet channels 2312.

[0026] The rotation range of fan 300 covers both the first and second working positions, for example... Figure 3 As shown, when the fan 300 is in one of its first operating positions, the air outlet of the fan 300 faces the interior of the seating space 101, and sends the air from the outside of the awning 230 into the seating space 101 through the air inlet channel; for example... Figure 4 As shown, when the fan 300 is in one of the second working positions, the air outlet of the fan 300 faces the outside of the awning 230, thereby supplying air to the outside of the awning 230.

[0027] The number of fans 300 can be one or more. In the illustration, there is one fan 300, centered along the width of the vehicle body. Figure 1 and Figure 2 As shown, in one embodiment, the corresponding bases of the support rods 232 of the awning 230 are rotatably connected, allowing the awning 230 to have an unfolded state and a retracted state. The awning fabric 233 includes a movable piece 2331 spread out on the support rods 232, and an extension piece 2332 located at the outermost movable piece 2331. The movable piece 2331 is flexible; when retracted, adjacent support rods 232 move closer together, and when unfolded, adjacent support rods 232 move further apart. The movable piece 2331 adapts to the unfolding and retracting process. The extension piece 2332 has a preset position for mounting the fan 300, for example, along the width direction, the preset position is located at the middle of the extension piece 2332.

[0028] like Figure 3 and Figure 5 As shown, in one embodiment, the fan 300 includes a housing 310, an impeller 320, and a motor (obscured and not visible). The housing 310 includes an impeller cover 311 forming an assembly space for the impeller 320, preventing users' and operators' fingers from entering the assembly space and improving safety. The impeller 320 is rotatably mounted within the impeller cover 311. The motor is driven by the impeller 320 to rotate. Correspondingly, the fan 300 has an axial direction around which the impeller 320 rotates. The impeller cover 311 is rotatably connected to the mounting base 231. This embodiment provides an assembly method between the impeller cover 311 and the mounting base 231. For example, the impeller cover 311 is provided with an adapter 3111, and the mounting base 231 is provided with an adapter 2311 connected to the adapter 3111.

[0029] For ease of assembly and manufacturing, the housing 310 includes a control box 312. The control box 312 contains a power module and a control circuit, which are electrically connected to both the power module and the motor. The control box 312 has a charging port electrically connected to either the power module or the control circuit. In one embodiment, the fan 300 and the mounting base 231 are detachably connected. Combined with the aforementioned assembly method between the impeller cover 311 and the mounting base 231, the adapter 3111 and the adapter base 2311 can be separated. During charging, the fan 300 can be detached for charging. After charging is complete, the adapter 3111 and the adapter base 2311 are reconnected, and the fan is reinstalled.

[0030] In one embodiment, a damping structure is provided between the mounting base 231 and the fan 300. The damping structure is configured to maintain the current airflow direction of the fan 300 without external force, thus preventing the fan 300 from rotating unexpectedly due to vibration during the movement of the stroller. In conjunction with the foregoing, the damping structure includes an adapter portion 3111 and an adapter base 2311. The adapter portions 3111 are two in number and are columnar structures. The adapter base 2311 is provided with a groove structure that mates with the columnar structure. The adapter portions 3111 and the adapter base 2311 are tightly fitted together to generate a damping force. In actual operation, an external force is manually applied to the fan 300 to adjust the airflow direction.

[0031] See also Figure 5 In one embodiment, the housing 310 is located outside the awning 230, and the impeller cover 311 and the control box 312 are arranged upward and backward along the fan axis. When the fan 300 is in the first working position, the operator can hold the control box 312 to adjust the fan 300. When the fan 300 is in the second working position, the operator can hold the impeller cover 311 to adjust the fan 300.

[0032] For ease of control, the surface of the control box 312 is provided with an input module 3121 and a display module 3122. The input module 3121 and the display module 3122 are electrically connected to the control circuit. The input module 3121 is used to receive user operation commands, and the display module 3122 is used to display the operating parameters of the fan 300. For example, the input module 3121 includes a first button for changing the rotational speed of the impeller 320, and the display module 3122 includes a display screen on the surface of the control box 312, which can be used to display the gear, and the gear corresponds to the rotational speed of the impeller 320.

[0033] The outdoor transport device of this application has a fan mounted on a sunshade and capable of rotating relative to the sunshade. Compared with the prior art, it offers more air delivery directions and can be adjusted to the optimal air delivery angle for the user. Furthermore, the air delivery direction can be adjusted without adjusting the handrail or other components, resulting in higher safety during use.

[0034] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0035] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
