Abstract
Description
Technical Field
[0001] This utility model relates to the field of child safety seat technology, and more specifically, to a child safety seat and a gesture sensing device. Background Technology
[0002] With the development of technology and people's increasing emphasis on children's travel safety and comfort, the functions of car child safety seats are constantly being upgraded. Traditional child safety seats have relatively simple functions, mainly serving to restrain children. However, today's child safety seats have more functions, such as seat angle adjustment and built-in entertainment device controls, to improve children's comfort and safety during car rides.
[0003] However, current child safety seats typically use touch-based controls such as buttons and knobs. These components are easily damaged by children, and parents must physically touch them to control the seat, which is very inconvenient. Utility Model Content
[0004] The purpose of this invention is to provide a child safety seat and a gesture sensing device, which can at least partially solve the above-mentioned technical problems.
[0005] In a first aspect, this utility model provides a child safety seat, which includes a seat body, a base, a gesture sensor, and a controller. The seat body includes a seat frame and a backrest.
[0006] The chair body and the backrest are integrally formed and set at a preset angle;
[0007] The backrest is a U-shaped backrest, including one side and two sides facing each other;
[0008] The gesture sensor is disposed on the side;
[0009] The seat body is adjustablely mounted on the base via an adjustment assembly;
[0010] The controller is electrically connected to the gesture sensor and the adjustment component, respectively, and is installed and fixed inside the base.
[0011] Optionally, the base includes a mounting part, a chair body support part, and a backrest support part;
[0012] The chair body support and the backrest support are integrally formed, and the mounting part is disposed on the chair body support;
[0013] The mounting part is adapted to the shape of the chair body, and the chair body is installed in the mounting part;
[0014] The backrest support is fitted to fit the backrest.
[0015] Optionally, the base is provided with a charging port for charging the power module of the controller.
[0016] Optionally, the child safety seat includes two gesture sensors, each of which is electrically connected to the controller.
[0017] Secondly, this utility model provides a gesture sensing device, which is applied to any of the above-mentioned child safety seats. The gesture sensing device includes a gesture sensor, a controller, and an adjustment component.
[0018] The controller is electrically connected to the gesture sensor and the adjustment component, respectively.
[0019] The beneficial effects of the child safety seat and gesture sensing device provided by this utility model are:
[0020] By installing gesture sensors and controllers on child safety seats, users can adjust the child safety seat simply by using gestures. The controller will then generate corresponding control commands through the gesture sensors to control the child safety seat without requiring the user to touch it, thus preventing damage to the child safety seat's contact parts by the child.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0034] Traditional electrically controlled child seats mostly use button controls, with physical buttons on the seat base. Pressing different buttons adjusts functions such as backrest angle and seat height. For example, pressing a specific button activates a motor to change the backrest angle.
[0035] However, buttons are often positioned low, requiring the operator to bend over, making operation cumbersome, especially in dimly lit environments. Secondly, children are active and may press buttons indiscriminately during rides, potentially altering the seat's position and posing a safety risk. Furthermore, frequent and prolonged pressing can cause wear and tear, poor contact, and other malfunctions, reducing the device's reliability and lifespan, and increasing maintenance costs.
[0036] Some child car seats use touch-sensitive technology, with touch panels located on the armrests, backrests, etc., to adjust seat functions. For example, different touch areas on the touch panel correspond to operations such as adjusting the seat angle and turning on the heating function.
[0037] However, this solution represents an improvement over traditional button control and is relatively convenient to operate. It is still a contact-based control system, requiring the user to touch the panel to complete operations. This can lead to a poor user experience for users who dislike touching unfamiliar objects or have hand disabilities. Furthermore, the touch panel is prone to getting dirty or sweaty, affecting the sensitivity and lifespan of the touch sensor.
[0038] Based on the above, this specification provides a child safety seat and a gesture sensing device, which can effectively alleviate the above-mentioned technical problems.
[0039] Please see Figure 1 This embodiment provides a child safety seat 01, which includes a seat body 10, a base 20, a gesture sensor 30, and a controller 50. The seat body 10 includes a seat frame 11 and a backrest 12.
[0040] The chair body 11 and the backrest 12 are integrally formed and set at a preset angle.
[0041] The backrest 12 is a U-shaped backrest 12, which includes two sides 121 facing each other.
[0042] The gesture sensor 30 is located on the side 121.
[0043] The seat body 10 is adjustablely mounted on the base 20 via the adjustment component 60.
[0044] The controller 50 is electrically connected to the gesture sensor 30 and the adjustment component 60, and is installed and fixed inside the base 20.
[0045] The preset angle can be any angle less than 90 degrees, conforming to ergonomic principles. For example... Figure 1 As shown, an adjustment component 60 is provided between the seat body 10 and the base 20, and the adjustment component 60 is electrically connected to the controller 50. When the seat body 10 needs to be adjusted (such as longitudinal angle adjustment or lateral angle adjustment), the user can make a corresponding gesture within the sensing range outside the gesture sensor 30. After receiving the gesture signal, the controller 50 determines the type of gesture made by the user, and then generates a corresponding control command based on the gesture type, ultimately controlling the adjustment component 60 to perform the corresponding seat adjustment.
[0046] In this embodiment of the utility model, the gesture sensor 30 is set on the backrest 12 away from the chair body 11 and on the outer side of the side 121. This can prevent children from accidentally touching the gesture sensor 30 while sitting normally, and also ensure that the gesture sensor 30 can effectively receive the signal when the user performs gestures.
[0047] The gesture sensor 30 recognizes gestures via an electric field (E-field). When an alternating voltage is applied to the electrodes of the gesture sensor 30, a quasi-static near-field electric field (e.g., ...) is generated. Figure 5 (As shown). The human body is conductive. When a hand or finger enters the electric field, the electric field is distorted. The field lines are attracted to the hand and grounded due to the conductivity of the human body, resulting in a local reduction in the electric field. The gesture sensor 30 detects changes in the electric field at different locations through at least four receiving (Rx) electrodes and acquires signals. These signals are transmitted to the controller 50, where they are processed and analyzed based on digital signal processing (such as DSP) algorithms and feature implementations. By matching the detected signal change patterns with the preset gesture model, such as an advanced random classification algorithm based on a Hidden Markov Model (HMM), the gesture is recognized.
[0048] For example, when a user makes a downward gesture within the sensing range (0-30cm) of the gesture sensor 30, the hand movement causes a specific distortion in the electric field. The electric field signals detected by the multiple receiving electrodes of the gesture sensor 30 will change accordingly, and these changed signals are transmitted to the controller 50. The controller 50 analyzes the trend, amplitude, and other characteristics of the signal changes based on a built-in algorithm. If, within a specific time period, the changes in electric field intensity detected by the multiple receiving electrodes match a preset signal change pattern for a downward gesture, the user's gesture will be recognized as a downward gesture.
[0049] In addition, users can also perform gesture recognition by drawing circles. For discrete circle gestures, when the user completes the drawing motion within the sensing area, and the hand stops moving or leaves the detection area, the receiving electrode of the gesture sensor 30 detects the change in electric field signal, and the controller 50 processes these signals. By matching them with a preset discrete circle gesture model, the controller determines whether the circle is drawn clockwise or counterclockwise.
[0050] After recognizing the user's gestures, the controller 50 generates control commands corresponding to each gesture based on a preset correspondence to control the seat body 10. For example, when the gesture is downward, the controller 50 controls the tilt motor of the adjustment component 60 to tilt downward, thereby lowering the backrest 12 of the seat body 10; when the gesture is upward, the controller controls the tilt motor to tilt upward, causing the backrest 12 to tilt upward; when the gesture is left / right, the controller 50 controls the rotation motor of the adjustment component 60 to rotate 90 degrees to the left / right; when the gesture is drawing a circle, the controller 50 controls the fan to turn on to ventilate the seat body 10; when the gesture is clenching a fist, the controller 50 controls the fan to turn off, and so on.
[0051] Optionally, the base 20 includes a mounting part 21, a chair body support part 22, and a backrest support part 23.
[0052] The chair body support 22 and the backrest support 23 are integrally formed, and the mounting part 21 is provided on the chair body support 22.
[0053] The mounting part 21 is adapted to the shape of the chair body 11, and the chair body 11 is installed in the mounting part 21. The backrest support part 23 is set to fit against the backrest 12.
[0054] like Figure 1 , Figure 2 As shown, the mounting part 21 is provided on the base 20, which can effectively maintain the stability of the seat body 10 on the base 20. At the same time, the backrest support part 23 can ensure that the seat body 10 will not tilt backward during adjustment.
[0055] Optionally, the base 20 is provided with a charging port 24 for charging the power module of the controller 50.
[0056] like Figure 2 As shown, a charging port 24 is provided at the rear end of the base 20. When the child safety seat 01 is out of power, it can be charged by connecting an external power source to the charging port 24, thereby ensuring the power supply of the child safety seat 01 during use.
[0057] In another alternative implementation, the child safety seat 01 can be powered directly via a wired connection. When the power is on, the child safety seat 01 is powered on, and when the wire is unplugged, the child safety seat 01 is de-powered.
[0058] Optionally, the child safety seat 01 includes two gesture sensors 30, each of which is electrically connected to the controller 50.
[0059] Please see Figure 3 To further facilitate user operation, a gesture sensor 30 can be installed on each side of the backrest 12 of the child safety seat 01 at opposite positions. This way, the user can easily adjust the child safety seat 01 regardless of which side it is on.
[0060] To ensure that children are not ejected from the child safety seat 01 during vehicle acceleration / deceleration, Figure 3 For example, two adjustable seat belts 40 can be installed on the child safety seat 01.
[0061] Based on the same inventive concept, this utility model provides a gesture sensing device 02, which is applied to the child safety seat 01 described above. The gesture sensing device 02 includes a gesture sensor 30, a controller 50, and an adjustment component 60. The controller 50 is electrically connected to the gesture sensor 30 and the adjustment component 60, respectively.
[0062] like Figure 4 As shown, after the gesture sensor 30 collects the user's gesture signal, it sends it to the controller 50. After the controller 50 recognizes the user's gesture, it generates a corresponding control command and controls the adjustment component 60 to make corresponding adjustments based on the control command.
[0063] The specific functions and structures of each part have been described in detail in the embodiments of the child safety seat 01 provided in this manual, and will not be elaborated here.
[0064] By adopting the above-described solution in the embodiments of this utility model, it is possible to:
[0065] By installing gesture sensors and controllers on child safety seats, users can adjust the child safety seat simply by using gestures. The controller will then generate corresponding control commands through the gesture sensors to control the child safety seat without requiring the user to touch it, thus preventing damage to the child safety seat's contact parts by the child.
[0066] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
