Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of infant carrier equipment, specifically to a shoulder pressure sensing and airbag automatic adjustment structure. Background Technology
[0002] Traditional baby carriers often suffer from high shoulder pressure, which can easily cause shoulder pain for parents after prolonged use. Ordinary carriers rely on fixed shoulder pads or thickened foam for cushioning, but they lack the ability to dynamically adjust according to the baby's weight and cannot maintain optimal comfort under different loads. In addition, the market currently lacks intelligent weight-sensing pressure relief solutions, so parents still have to bear a lot of shoulder pressure, reducing the comfort of holding the baby for a long time. Therefore, how to automatically adjust the shoulder support intensity based on pressure sensing to reduce shoulder burden has become a major technical pain point in the field of baby carriers. To address this, we propose a shoulder pressure sensing and airbag automatic adjustment structure. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] In view of the shortcomings of the prior art, this utility model provides a shoulder pressure sensing and airbag automatic adjustment structure to solve the above-mentioned problems in the prior art.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a shoulder pressure sensing and airbag automatic adjustment structure, including a shoulder strap body and two shoulder straps, each of which is provided with an inflatable airbag. The shoulder strap body is provided with a control box and a pressure sensor. The pressure sensor is installed at the force-bearing part of the shoulder strap and is used to detect the tension on the shoulder strap.
[0007] The control box contains a control circuit and is connected to a miniature air pump. The miniature air pump is connected to the inflatable airbag through an air duct. When the pressure sensor detects that the shoulder strap tension reaches a preset pressure threshold, the control circuit drives the miniature air pump to inflate the inflatable airbag to fill the shoulder strap padding area. When the shoulder strap pressure drops below the preset pressure threshold, the control circuit controls the miniature air pump to expel air, causing the inflatable airbag to deflate and retract.
[0008] Furthermore, the shoulder strap is provided with two or more interconnected airbag units, which are distributed along different areas of the shoulder.
[0009] Furthermore, the pressure sensor is a strain gauge sensor, installed at the fulcrum where the shoulder strap connects to the main body of the carrier, and is used to indirectly measure the tension of the shoulder strap on the baby's weight.
[0010] Furthermore, the pressure sensor is a flexible pressure-sensitive sensor, which is installed inside the intersection of the shoulder strap and the shoulder.
[0011] Furthermore, the control box has buttons on the front for adjusting preset pressure thresholds, and the control box has a built-in Bluetooth module for connecting to external mobile terminals.
[0012] Furthermore, the miniature air pump and control circuit are integrated into the control box, which is detachably mounted on the front chest position of the main body of the shoulder strap, and the control box is equipped with a display device to display the airbag inflation status and pressure level.
[0013] Furthermore, the material of the inflatable airbag is a multilayer composite elastic film.
[0014] Furthermore, the operating noise of the micro air pump is less than 40dB.
[0015] (III) Beneficial Effects
[0016] This utility model embodiment provides a shoulder pressure sensing and airbag automatic adjustment structure. It has the following beneficial effects:
[0017] 1. By incorporating pressure sensors and inflatable airbags into the baby carrier, dynamic shoulder support adjustment is achieved. Compared to existing products that only provide fixed cushioning, this design can sense changes in shoulder strap pressure in real time and automatically inflate or deflate. When the shoulder pressure exceeds a preset threshold, a micro air pump automatically inflates the shoulder pad airbags to reduce the pressure of the shoulder straps on the shoulders. When the pressure decreases, it automatically deflates to restore its original shape. This closed-loop control cushioning structure can adjust in real time according to the baby's weight and movements, effectively relieving shoulder pressure caused by carrying the baby for a long time, and improving the comfort and ergonomics of the baby carrier.
[0018] 2. The pressure threshold and inflation level can be set via the control box buttons or an application on an external mobile terminal to meet the needs of different user body types and preferences, thus solving the problem of traditional shoulder straps not being able to dynamically reduce pressure.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Example 1
[0026] See attached document Figure 1-3 A shoulder pressure sensing and airbag automatic adjustment structure includes a shoulder strap body 1 and two shoulder straps 2. Each shoulder strap 2 has an inflatable airbag 3 embedded in its inner side, covering the shoulder stress area. The airbag is made of wear-resistant and leak-proof material. When inflated, it increases the contact area between the shoulder strap 2 and the shoulder, dispersing pressure. After deflating and shrinking, the shoulder strap 2 returns to its original soft thickness, making it convenient to wear normally.
[0027] The main body 1 of the baby carrier is equipped with a control box 4 and a pressure sensor 5. The pressure sensor 5 is installed at the force-bearing part of the shoulder strap 2 and is used to detect the tension on the shoulder strap 2. The pressure sensor 5 is a strain gauge sensor and is installed at the fulcrum where the shoulder strap 2 is connected to the main body 1 of the baby carrier. It is used to indirectly measure the tension of the baby's weight on the shoulder strap 2 and obtain the force data of the baby's weight on the shoulder. When the monitored value reaches the preset pressure threshold, a trigger signal is generated.
[0028] The control box 4 contains a control circuit and is connected to a miniature air pump 6. The miniature air pump 6 is connected to the inflatable airbags 3 in the left and right shoulder straps 2 through air guide tubes 7. The miniature air pump 6 is driven by the control circuit. When the pressure sensor 5 detects that the tension of the shoulder strap 2 reaches the preset high pressure threshold, the control circuit drives the miniature air pump 6 to inflate the inflatable airbags 3 to fill the shoulder pad area of the shoulder strap 2 and reduce the pressure per unit area of the shoulder. When the pressure of the shoulder strap 2 drops below the preset low pressure threshold, the control circuit controls the miniature air pump 6 to deflate, so that the inflatable airbags 3 deflate and retract.
[0029] Preferably, a solenoid valve or a one-way valve is provided in the circuit of the inflatable airbag 3 to control the airflow direction. When inflation is required, the inflation passage is opened, and when deflation is required, the deflation passage is opened to ensure that the inflation and deflation process of the inflatable airbag 3 is controllable and safe.
[0030] In this embodiment, the shoulder strap 2 is provided with two or more interconnected airbag units, which are distributed along different areas of the shoulder to provide a more uniform support and pressure relief effect.
[0031] In this embodiment, the control box 4 is equipped with a human-machine interface, which includes buttons, a display screen and a Bluetooth module. The buttons are used to adjust the preset pressure threshold, the Bluetooth module is used to connect to external mobile terminals, such as mobile phones and tablets, and the display screen is used for status display.
[0032] In this embodiment, the miniature air pump 6 and the control circuit are integrated into the control box 4. The control box 4 is detachably installed at the front chest position of the shoulder strap body 1, and the control box 4 is equipped with a display device to display the airbag inflation status and pressure level.
[0033] In this embodiment, the material of the inflatable airbag 3 is a multi-layer composite elastic film, which ensures a service life of more than 5,000 repeated inflation and deflation cycles without leakage.
[0034] In this embodiment, the operating noise of the miniature air pump 6 is less than 40dB to ensure a quiet environment for the baby.
[0035] Example 2
[0036] This second embodiment has a structure that is basically the same as that of the first embodiment, the difference being: (Refer to Appendix) Figure 4 The pressure sensor 5 is a flexible pressure-sensitive sensor, which is installed inside the intersection of the shoulder strap 2 and the shoulder, and is located in the middle of the inflatable airbag 3, so as to avoid the pressure sensor 5 being unable to contact the shoulder after the inflatable airbag 3 is inflated, thus preventing the inability to provide an accurate pressure signal.
