Description

Technical Field

[0001] This utility model belongs to the field of children's furniture technology, and in particular relates to a children's bed with a height recognition function. Background Technology

[0002] Furnishing a child's room requires investing in several pieces of furniture, and a children's bed is an essential one. With the improvement of people's living standards, most families buy a crib when a newborn is born. However, most cribs become unusable when the child is 3 or 4 years old, requiring the purchase of a different crib to meet the child's needs. As children grow from toddlers to teenagers, their needs for a bed gradually increase; that is, as children grow taller, the length of the bed must be adjusted to meet their growing needs.

[0003] Traditional children's beds have a fixed length and cannot automatically adjust to the size as the child grows, requiring parents to replace the bed regularly, increasing household expenses and failing to fully utilize the bed's functionality. Of course, there are also extendable children's beds available, but these are mostly adjusted manually, which is inconvenient to operate and cannot keep up with the child's growth rate, resulting in limited functionality. Utility Model Content

[0004] This utility model addresses the technical problems existing in the use of children's beds mentioned above, and proposes a children's bed with a reasonable design, simple structure, convenient processing, and the ability to easily adjust the length of the children's bed. In particular, it can match the needs of children of different heights at different stages, fully improve its practicality, and meet different usage needs. It is a children's bed with a height recognition function.

[0005] To achieve the above objectives, the present invention adopts a technical solution of a children's bed with a height recognition function, comprising a children's bed body. The children's bed body is characterized by comprising a three-section structure consisting of a headboard, a bed frame, and a footboard that are slidably connected to each other, and has a built-in height intelligent recognition module, an electric telescopic device, and a control device. The height intelligent recognition module drives the electric telescopic device to automatically adjust the length of the children's bed body by measuring distance data.

[0006] Preferably, the headboard and footboard are respectively provided with grooved and parallel headboard and footboard frames on one side, and the bed frame is provided with sliding plates that match the grooves of the two adjacent parallel frame plates.

[0007] Preferably, the telescopic device is fixed to the bottom of the headboard and footboard respectively by corner brackets, and the driving stroke of the telescopic device is positively correlated with the child's growth rate.

[0008] Preferably, the height intelligent recognition module includes at least one of an ultrasonic sensor, a ToF camera, and a pressure sensor array.

[0009] Preferably, the bottom of the bed is provided with a brake wheel with braking function, and the bottom of the foot of the bed is provided with a directional wheel.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. This utility model provides a children's bed with height recognition.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-6As shown, a children's bed with a height recognition function includes a bed body, which is made of a three-section structure, specifically consisting of a headboard 1, a bed frame 3, and a footboard 2. The headboard 1 generally includes a headboard panel, which facilitates the installation of the headboard frame 11. The headboard panel also has mounting holes for the installation of a height recognition module 5. The bed frame 3 generally includes a bed frame and bed legs located on both sides below the bed frame to ensure stability. A sliding plate 31 is provided on the outer side of the bed frame to cooperate with the headboard 1 and the footboard 2. The footboard 2 generally includes a footboard to facilitate the installation of the footboard frame 21. Both the headboard 1 and the footboard 2 can slide relative to the bed frame 3 to meet the length adjustment requirements under different usage conditions. To further improve the rational design of the children's bed body... The children's bed body is equipped with a built-in intelligent length recognition module 5, an electric telescopic device 4, and a control device 42. The intelligent length recognition module 5 drives the electric telescopic device 4 to automatically adjust the length of the children's bed body through distance measurement data. There are two sets of intelligent length recognition modules 5, located at the headboard 1 and the footboard 2 respectively. In more detail, the intelligent length recognition module 5 uses one or more combinations of ultrasonic rangefinder, ToF camera, and pressure sensor array. The electric telescopic device 4 is the adjustment mechanism connecting the headboard 1 and the footboard 2, allowing it to slide to adjust the length. Specifically, the children's bed body adopts a three-section design. The telescopic device is installed at the bottom of the three sections of the bed body, forming a sliding pair with the grooved slatted frame plates at the headboard 1 and the footboard 2. When the intelligent length recognition module 5 detects an increase in the child's height, it controls the control device 42 to activate the telescopic device, which pushes the footboard 2 to move through the corner bracket 44, thereby realizing the adjustment of the bed body length.

[0024] The working principle of the telescopic device is as follows: The telescopic device consists of a motor 43, a control device 42, a threaded rod 46, a threaded nut tube 45, and a bracket 44. The control device 42 is located in the threaded nut tube inside the control box 41. When the motor 43 rotates forward, the double-headed output shaft of the motor 43 rotates clockwise, driving the threaded rod 46 connected to the two ends of the output shaft to rotate clockwise. The threaded rod and the threaded nut 47 rotate in the opposite direction. Since the nut and the nut tube are embedded in each other, the nut tube extends outward, and the thrust drives the bed 3 away from the headboard 1, that is, the footboard 2 extends backward, thereby increasing the length of the bed to meet the needs of the child's height. Conversely, when the motor 43 rotates in reverse, the double-headed output shaft of the motor 43 rotates counterclockwise, driving the threaded rod connected to the double-headed output shaft to rotate counterclockwise. Since the nut and the nut tube are embedded in each other, when the nut tube retracts inward, the thrust drives the bed 3 to move closer to the headboard 1, that is, the footboard 2 retracts forward, thereby shortening the length of the bed.

[0025] In the above process: through the three-stage sliding structure cooperating with the multi-modal body length detection system, the automatic adaptive adjustment of the bed length can be achieved. By adopting the ultrasonic, ToF vision and pressure sensing fusion detection technology, combined with the telescopic device actuator, it can accurately track the growth curve of children and automatically expand the bed size, solving the technical problem that traditional children's beds need to be frequently replaced. This device is reasonably designed, simple in structure, convenient to process and can achieve the convenient adjustment of the use length of the children's bed. In particular, it can match the needs of children's different heights at different stages for the bed, fully improving its practicability and meeting different use requirements.

[0026] To ensure the convenience of adjusting the children's bed body, a headboard row frame 11 and a footboard row frame 21 with grooves and parallelly arranged are respectively provided on one side of the headboard 1 and the footboard 2. Among them, for the grooves in the headboard row frame 11 and the footboard row frame 21, they are designed in the shape of a Chinese character "zhong". On the one hand, it provides convenience for the placement of the sliding plate 31 and can also limit its movement adjustment. A sliding plate 31 matching the grooves of two adjacent parallel row frame plates is provided on the bed body 3. The cooperation between the above structures constitutes a guiding mechanism for the headboard 1 and the footboard 2 to slide relative to the bed body 3 respectively. That is to say: the above row frame plates with grooves are respectively connected to the headboard 1 and the footboard 2, and the sliding plate 31 provided on the bed body 3 can be adaptively corresponding to the grooves of the row frame plates. Of course, the number of row frame plates is at least two, and the number of sliding plates 31 is one less than the number of row frame plates, which fully ensures the smooth adjustment between components and meets the use requirements.

[0027] To ensure that the children's bed body can achieve telescopic adjustment, the telescopic device is respectively fixed to the bottoms of the headboard 1 and the footboard 2 through corner codes 44. The driving stroke of the telescopic device is positively correlated with the growth rate of children, so as to accurately track the growth of children and automatically expand the bed size, solving the technical problem that traditional children's beds need to be frequently replaced.

[0028] To further ensure the smoothness of the children's bed body during the adjustment process, a braking wheel 7 with a braking function is provided at the bottom of the bed body 3, and a directional wheel 6 is provided at the bottom of the footboard 2. Among them, for the established braking wheel 7, it is actually a directional wheel with a braking function. On the one hand, after it is braked, it prevents the bed body from moving freely and affecting stability. On the other hand, after the braking is cancelled, it can achieve the convenient adjustment of the position of the children's bed body and meet the use requirements of different placement positions. For the directional wheel 6 provided at the bottom of the footboard 2, its function is to ensure more convenience and smoothness during the length adjustment and improve the use functionality of the device.

[0029] Example 2, such as Figure 7As shown, the height intelligent recognition module 5 provided in this embodiment can use a distance measuring module, specifically an ultrasonic sensor, which is laid on the headboard 1 and footboard 2 respectively. The probe in the distance measuring module is aimed at the human head. When the distance measuring module works, it measures the distance to the head and feeds it back to the control device 42. The probe of another distance measuring module is aimed at the human feet to detect and feeds it back to the control device 42. The feedback data is transmitted to the control device 42. Using the program set in the control device 42, the reflection time difference of the two ultrasonic sensors is calculated. By comparing the original stored ultrasonic sensor and reflection time data, the height data is calculated from the change in the time difference. When the height increase exceeds 2cm for 3 consecutive times, the adjustment program telescopic device motor 43 is triggered to rotate forward. The 3 sections of the bed body and the headboard 1 and footboard 2 sections telescopic, and the bed bottom directional wheels 6 complete the smooth telescopic movement. In this way, by using the above-mentioned ultrasonic, ToF vision and pressure sensing fusion detection technology, combined with the telescopic device to perform telescopic action, the bed size can be automatically expanded by accurately tracking the child's growth curve, solving the technical problem of the need for frequent replacement of traditional children's beds.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
