Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0047] See Figures 1 to 5 As shown, according to an embodiment of this application, a car child safety seat is provided, which includes a seat body 10 and a sunshade assembly 20.

[0048] The chair body 10 includes a headrest 11; a light-blocking and sun-shading assembly 20 is mounted on the headrest 11, and the light-blocking and sun-shading assembly 20 includes a controller (not shown), a drive component 22, and a light-blocking and sun-shading component 23. The light-blocking and sun-shading component 23 includes at least two light-blocking and sun-shading canopies 231, each having a folded position and an open position for light-blocking and sun-shading. The drive component 22 is connected to the light-blocking and sun-shading component 23 to drive the light-blocking and sun-shading component 23 to switch between the folded position and the light-blocking and sun-shading position. The controller is communicatively connected to the drive component 22 to control the drive component 22.

[0049] In actual use, the car child safety seat in this embodiment is installed in the back seat of the car, and the controller is integrated with the car's control system. When the car is in motion, if it is necessary to adjust the sunshade for the baby, the drive component 22 can be controlled on the controller. When the controller controls the drive component 22 to move, it can drive at least two sunshade awnings 231 of the sunshade component 23 to fold or open with each other, thereby switching between the folded position and the sunshade position. Ultimately, the sunshade for the baby can be adjusted. The structure is simple and convenient for users to operate and use while driving.

[0050] In some embodiments, the shading canopy 231 consists of two pieces, both of which are square, such as rectangular or square. The accompanying drawings show the case where the shading canopy 231 is rectangular. One side of each of the two shading canopies 231 is hinged together by a hinge rod 232. When the driving component 22 drives the two shading canopies 231 to open up, the shading canopy 231 is in a shading position. When the driving component 22 drives the two shading canopies 231 to be stacked, the shading canopy 231 is in a folded position. Specifically, the driving component 22 drives the two shading canopies 231 to rotate along the hinge rod 232, switching between the shading position and the folded position. The structure is simple and easy to implement. Of course, in other embodiments of this application, the shading canopy 231 can be set as three or more pieces, and the arrangement of the three or more shading canopies 231 can be umbrella-shaped. Any other variations under the concept of this application are within the protection scope of this application.

[0051] For ease of distinction, in this embodiment, the two shading and sunshade awnings 231 are respectively labeled as the first shading and sunshade awning 231a and the second shading and sunshade awning 231b. The first shading and sunshade awning 231a has a first support rod 237 on the side opposite to the hinge rod 232, and the second shading and sunshade awning 231b has a second support rod 238 on the side opposite to the hinge rod 232. The shading and sunshade component 23 also includes a support frame 233, a guide rail 234, and a connecting component 235.

[0052] The support frame 233 is installed at the top of the headrest portion 11, and the support frame 233 has a support beam 2331 suspended at the top of the headrest portion 11; the guide rail 234 is vertically installed on the support beam 2331 and extends in a direction away from the support beam 2331; the connecting assembly 235 includes a first connecting rod 2351 and a second connecting rod 2352, the first connecting rod 2351 is disposed on the side of the first shading canopy 231a, and the first end of the first connecting rod 2351 is perpendicularly connected to the first support rod 237. The first connecting rod 2351 is hinged to the support beam 2331. The second end of the first connecting rod 2351 is perpendicularly connected to the hinge rod 232. The second connecting rod 2352 is located on the side of the second shading and sunshade 231b. The first end of the second connecting rod 2352 is hinged to the second end of the first connecting rod 2351. The second end of the second connecting rod 2352 is slidably mounted on the guide rail 234. The driving component 22 is drivenly connected to the second connecting rod 2352 to drive the second end of the second connecting rod 2352 to slide along the guide rail 234.

[0053] Specifically, when the driving component 22 drives the second end of the second connecting rod 2352 to slide along the guide rail 234, the first end of the second connecting rod 2352 rotates around the first connecting rod 2351 and pushes the first shading awning 231a and the second shading awning 231b to move so that the shading component 23 switches between the folded position and the shading position.

[0054] In one embodiment, the second end of the second connecting rod 2352 is connected to the guide rail 234 via a slider 236, and the driving component 22 includes a direct drive motor (not shown in the figure), which is connected to the slider 236 to drive the slider 236 to reciprocate along the guide rail 234. The structure is simple and easy to implement.

[0055] In another embodiment, the second end of the second connecting rod 2352 is also connected to the guide rail 234 via the slider 236, and the driving component 22 includes a rotary motor (not shown) and a linkage assembly. The rotary motor is mounted on the headrest portion 11 and communicates with the controller; the linkage assembly connects the rotary motor and the slider 236. The rotation of the rotary motor drives the linkage assembly to move, causing the slider 236 to slide along the guide rail 234, thereby enabling the sunshade component 23 to switch between a folded position and a sunshade position.

[0056] Exemplarily, the linkage assembly in this embodiment includes a first linkage 221 and a second linkage 222. The first linkage 221 is L-shaped, and its first end is connected to a rotary motor. The two ends of the second linkage 222 are connected to the slider 236 and the second end of the first linkage 221, respectively. During operation, the rotary motor rotates, causing the first end of the first linkage 221 to rotate, which in turn moves the second linkage 222, causing the slider 236 to slide along the guide rail 234. This, in turn, allows the light-shielding and sun-shading component 23 to switch between a folded position and a light-shielding and sun-shading position. Of course, in other embodiments of this application, the linkage assembly may also include three or more linkages. Any other variation capable of driving the slider 236 to slide along the guide rail 234 is within the scope of protection of this application.

[0057] Furthermore, the car child seat also includes a limiting component 30, which is used to limit the swing angle of the first link 221, thereby limiting the movement stroke of the slider 236, so as to facilitate the control of the shading range of the sunshade component 23.

[0058] For example, the limiting component 30 includes a limiting sleeve 31 and a limiting rod 32. The limiting sleeve 31 is rotatably mounted on the headrest portion 11 and forms a mounting hole 312. A first limiting portion 311 is provided on the side wall of the limiting sleeve 31, and the first limiting portion 311 extends along the length direction of the mounting hole 312. The limiting rod 32 is slidably mounted in the mounting hole 312, and a second limiting portion 321 adapted to the first limiting portion 311 is provided on the side wall of the limiting rod 32. The end of the limiting rod 32 away from the limiting sleeve 31 is rotatably connected to the first connecting rod 221.

[0059] When the rotary motor rotates, the first connecting rod 221 rotates around its first end, which can drive the second connecting rod 222 to push the slider 236 to slide along the guide rail 234. During this process, the limiting rod 32 can extend and retract within the mounting hole 312. When the second limiting part 321 is limited by the first limiting part 311, the limiting rod 32 cannot continue to extend and retract. This can limit the first connecting rod 221 and the second connecting rod 222, thereby limiting the sliding stroke of the slider 236. The structure is simple and easy to implement.

[0060] Optionally, in this embodiment, one of the first limiting part 311 and the second limiting part 321 is a limiting groove, and the other is a limiting protrusion adapted to the limiting groove. That is, when the first limiting part 311 is set as a limiting groove, the second limiting part 321 is set as a limiting protrusion; when the first limiting part 311 is set as a limiting protrusion, the second limiting part 321 is set as a limiting groove. Through the interaction of the limiting groove and the limiting protrusion, the extension and retraction position of the limiting rod 32 can be limited. The structure is simple and easy to manufacture.

[0061] For example, in this embodiment, the limiting sleeve 31 is provided with a first limiting part 311 on both opposite sides, and correspondingly, the limiting rod 32 is provided with a second limiting part 321 on both opposite sides. The limiting is achieved by the cooperation of the two first limiting parts 311 and the two second limiting parts 321, and the structure is stable and reliable.

[0062] Of course, in other embodiments of this application, the limiting component 30 can also be a limiting block or other structure disposed on the guide rail 234. Any other variation within the concept of this application is within the protection scope of this application. Furthermore, in other embodiments of this application, the limiting component 30 may not be necessary; instead, the linear motor and rotary motor can be controlled by setting a control program.

[0063] Furthermore, the car child seat in this embodiment also includes at least one of a wind speed sensor (not shown in the figure), a temperature sensor (not shown in the figure), a light sensor (not shown in the figure), and a camera (not shown in the figure). The wind speed sensor, temperature sensor, light sensor, and camera are all mounted on the sunshade component 23. The wind speed sensor, temperature sensor, light sensor, and camera are all connected to the controller. The controller can automatically control the drive component 22 based on the signals transmitted by the wind speed sensor, temperature sensor, light sensor, and camera.

[0064] In other words, by setting a wind speed sensor (not shown in the figure), a temperature sensor (not shown in the figure), a light sensor (not shown in the figure), and a camera (not shown in the figure) on the sunshade component 23 in this embodiment, the control module can automatically control the sunshade component 23 according to the signals transmitted by the wind speed sensor (not shown in the figure), the temperature sensor (not shown in the figure), the light sensor (not shown in the figure), and the camera (not shown in the figure), making it easier to automatically adjust the sunshade for the baby during driving.

[0065] Based on the above structure, it can be seen that the car child safety seat of this application, by incorporating a wind speed sensor, a temperature sensor, a light sensor, and a camera, can transmit signals to the controller according to the varying brightness of the surrounding light and environmental conditions. The controller then controls the drive component 22 based on the signals transmitted from the wind speed sensor, temperature sensor, light sensor, and camera. The motor in the drive component 22 then begins to rotate, preparing for the sunshade action. The initial state is as follows: Figure 4 As shown. Subsequently, the first link 221, the second link 222, the slider 236, and the connecting assembly synchronously begin to move as driven members, as illustrated in the diagram. Figure 2 The shading and sunshade component 23 is in an unfolded state until it is fully opened, as shown. Figure 3As shown. At this time, the second limiting part 321 on the limiting rod 32 contacts one end of the first limiting part 311, and the upward movement stops. The motor of the driving component 22 is obstructed and automatically stops rotating, completing the unfolding action of the sunshade panel. When it is necessary to retract the sunshade panel, the motor in the driving component 22 sends a reverse action after receiving the command, the first connecting rod 221 begins to rotate in the opposite direction, and the sunshade component 23 retracts synchronously, presenting... Figure 4 The initial state.

[0066] See Figures 1 to 6 As shown, on the other hand, this application also provides a control method for a car child safety seat. The control method for the car child safety seat is implemented using the aforementioned car child safety seat. The control method includes: setting an automatic control mode on the controller; if automatic control is enabled, the controller controls the drive component 22 based on signals transmitted by at least one of the wind speed sensor, temperature sensor, light sensor, and camera; otherwise, manual control mode is enabled.

[0067] Specifically, if the signal transmitted by the wind speed sensor is greater than the first threshold, the controller controls the opening area of ​​the shading component 23 according to the wind speed range of the wind speed sensor. The correspondence between the first threshold, the wind speed range and the opening area can be determined experimentally, and is not specifically limited in this application.

[0068] Optionally, if the signal transmitted by the temperature sensor is greater than the second threshold, the controller controls the opening area of ​​the shading component 23 according to the temperature range of the temperature sensor. The correspondence between the second threshold, the temperature range, and the opening area can be determined experimentally and is not specifically limited in this application. When the wind speed exceeds the second threshold, it indicates that the wind speed is relatively fast and the air volume is large, which is not suitable for blowing directly onto a child's head. Therefore, when the wind speed is detected to exceed the second threshold, the controller controls the drive component 22 to operate, which can drive the shading component 23 to open a certain area for wind protection. Similarly, when the wind speed is detected to be lower than the second threshold, the controller controls the drive component 22 to operate, which can drive the shading component 23 to perform a closing action. The wind speed is generally below 0.35 m / s, which is a very comfortable wind.

[0069] Optionally, if the signal transmitted by the light sensor is greater than the third threshold, the controller controls the opening area of ​​the shading component 23 according to the light intensity range of the light sensor. The correspondence between the third threshold, the light intensity range and the opening area can be determined experimentally and is not specifically limited in this application.

[0070] Optionally, if the camera captures a baby sleeping in a car child safety seat, the controller automatically controls the drive component 22 to operate so that the sunshade component 23 is in the sunshade position, allowing the baby to fall asleep in dim light.

[0071] The child safety seat described in this application is organically integrated with the vehicle's intelligent system for overall control. The sunshade and light-blocking components of the child safety seat are normally closed, but can be activated via the car seat's on-screen control interface to automatically open these components, including intelligent light recognition. The on-screen control interface also displays the open / closed status of the sunshade and light-blocking components. When the baby needs to fall asleep, the sunshade and light-blocking components can also be manually opened or closed via the on-screen safety seat control interface, facilitating sun and light control for the baby while driving.

[0072] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0073] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0074] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
