Description

Technical Field

[0001] This utility model relates to the field of massage backpack technology, specifically to a pressure-sensitive massage backpack. Background Technology

[0002] Existing backpacks provide convenience for carrying items while traveling, but the weight of the items puts pressure on the shoulders, back, and waist of the user. Over time, this can lead to discomfort, fatigue, and pain, harming the user's health. With technological advancements, adding massage vibrations to traditional backpacks has enabled them to have a massage function and provide some relaxation. However, existing massage vibrations typically only offer basic massage functions and lack pressure-sensing massage capabilities. They cannot detect the user's weight in real time and therefore cannot automatically adjust the massage intensity based on the amount of weight, failing to meet the user's personalized service needs. Thus, further improvements to existing massage backpacks are needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pressure-sensitive massage backpack that can detect the user's load pressure in real time and automatically adjust the massage intensity according to the load pressure under the control of the massage control system, so as to provide personalized service to users.

[0011] Furthermore, the pressure-sensitive massage vibrator includes a pressure-sensitive top shell, a pressure sensor, a motor cover, a vibration motor, an eccentric block, and a fixed bottom shell. The fixed bottom shell has an upward-opening cavity. The motor cover is fixedly installed in the cavity of the fixed bottom shell. The motor cover and the fixed bottom shell together form a motor cavity in the middle and a shaft hole is formed on one side between them. The vibration motor is located in the motor cavity, and the motor shaft of the vibration motor passes through the shaft hole and is fixedly installed with an eccentric block located in the cavity. The pressure sensor is fixedly installed at the upper opening of the fixed bottom shell, and the pressure-sensitive top shell is fixedly installed on the upper end of the pressure sensor and covers the pressure sensor.

Detailed Implementation

[0029] The present invention will be further described below through specific embodiments.

[0030] Example 1

[0031] like Figures 1 to 11 As shown, the pressure-sensitive massage backpack of this utility model includes a backpack body 1, a massage control system, at least one first massage vibrator 3, and a power supply 4 disposed on the backpack body 1. The massage control system includes a PCB board 21 and a function control panel 22. The function control panel 22, the first massage vibrator 3, and the power supply 4 are all electrically connected to the PCB board 21. The first massage vibrator 3 is a pressure-sensitive massage vibrator, which is used to detect the pressure on the corresponding parts of the human body in real time and feed the pressure signal back to the massage control system. The massage control system adjusts the massage intensity of the pressure-sensitive massage vibrator in real time according to the received pressure signal. Thus, the pressure-sensitive massage backpack has a pressure-sensitive massage function, can detect the user's load pressure in real time, and can automatically adjust the massage intensity according to the load pressure under the control of the massage control system, providing personalized service to users.

[0032] The diagram illustrates how to adjust the massage intensity based on the weight of the person bearing the weight. Figure 9As shown, when there is no load, the pressure-sensitive massage vibrator will automatically turn off the massage; when the actual load is less than 1.6Kg (low load), the pressure-sensitive massage vibrator will be in micro-high frequency massage mode, for example, the massage cycle is 2 seconds, with a massage time and a pause time of 1 second each; when the actual load is between 1.6Kg and 3.2Kg (medium load), the pressure-sensitive massage vibrator will be in micro-medium frequency massage mode, for example, the massage cycle is 2 seconds, with a massage time of 0.75 seconds and a pause time of 1.25 seconds; when the actual load is greater than 3.2Kg (high load), the pressure-sensitive massage vibrator will be in low-medium frequency massage mode, for example, the massage cycle is 2 seconds, with a massage time of 0.5 seconds and a pause time of 1.5 seconds.

[0033] The pressure-sensitive massage backpack also includes at least one second massage vibrator 5, which is electrically connected to the PCB board 21. In addition, the second massage vibrator 5 can be a conventional massage vibrator or a pressure-sensitive massage vibrator.

[0034] Preferably, the power supply 4 is a power bank, and the function control panel 22, the first massage vibrator 3, the second massage vibrator 5, the power supply 4, and the PCB board 21 are all connected by cables.

[0035] The number of the first massage vibrator 3 and the second massage vibrator 5 are both 2-4. The first massage vibrator 3 is used to massage the shoulders of the human body, and the second massage vibrator 5 is used to massage the waist of the human body.

[0036] In addition, the backpack body 1 is provided with a control storage cavity for storing the PCB board 21, a power storage cavity for storing the power supply 4, a first massage storage cavity for storing the first massage vibrator 3, and a second massage storage cavity for storing the second massage vibrator 5, so as to facilitate the stable placement of the PCB board 21, the power supply 4, the first massage vibrator 3 and the second massage vibrator 5 on the backpack body 1.

[0037] The function control panel 22 includes a power switch button, such as... Figure 11As shown, in standby mode, when the power switch button is pressed and held, the first massage vibrator 3 and the second massage vibrator 5 of the pressure-sensitive massage backpack will be activated to start the massage. In massage mode, when the power switch button is pressed and held, the first massage vibrator 3 and the second massage vibrator 5 of the pressure-sensitive massage backpack will be deactivated to return to standby mode. In massage mode, when the power switch button is pressed briefly, the massage mode of the pressure-sensitive massage backpack will switch between the first massage mode, the second massage mode, and the third massage mode. The first massage mode is for shoulder and waist massage, the second massage mode is for shoulder massage only, and the third massage mode is for waist massage only. In addition, in massage mode, pressure detection is activated, and the massage intensity of the first, second, and third massage modes can be adjusted in real time according to different load pressures. The greater the load pressure, the lower the massage intensity, and the lower the load pressure, the greater the massage intensity. In massage mode, if no pressure is detected for 3 seconds, it is determined that the user has removed the backpack, and the massage will automatically turn off.

[0038] Accordingly, the PCB board 21 integrates a CPU 211, a pressure sensor detection module 212, a button detection module 213, a power filtering module 214, a first massage vibrator driving circuit module 215, and a second massage vibrator driving circuit module 216.

[0039] Preferably, the CPU 211 can be an STC8H1 K08 chip, the pressure sensor detection module 212 can be an HX711 chip, the button detection module 213 can realize button input control through a direct connection to the interrupt pin of the CPU 211, the power filtering module 214 can use surface-mount capacitors for power filtering, and the first massage vibrator drive circuit module 215 and the second massage vibrator drive circuit module 216 can use an N-channel MOSFET of I RML2502 to form a PWM DC motor speed controller to realize speed control of the vibration motor 34 in the first massage vibrator 3 and the vibration motor 34 in the second massage vibrator 5.

[0040] The pressure-sensitive massage vibrator includes a pressure-sensitive top shell 31, a pressure sensor 32, a motor cover 33, a vibration motor 34, an eccentric block 35, and a fixed bottom shell 36. The fixed bottom shell 36 has an upwardly open cavity 361. The motor cover 33 is fixedly installed in the cavity 361 of the fixed bottom shell 36. The motor cover 33 and the fixed bottom shell 36 form a motor cavity 371 in the middle and a shaft hole 372 on one side. The vibration motor 34 is located in the motor cavity 371, and the motor shaft of the vibration motor 34 passes through the shaft hole 372 and is fixedly installed with the eccentric block 35 located in the cavity 361. The pressure sensor 32 is fixedly installed at the upper opening of the fixed bottom shell 36. The pressure-sensitive top shell 31 is fixedly installed on the upper end of the pressure sensor 32 and covers the pressure sensor 32.

[0041] Preferably, the pressure sensor 32 is a dual half-bridge miniature weighing sensor.

[0042] The vibration motor 34 drives the eccentric block 35 to rotate, thereby causing the pressure-sensitive massage vibrator to vibrate accordingly, achieving a massage function and providing a certain relaxation effect. The motor cover 33 and the fixed bottom shell 36 facilitate the stable installation of the vibration motor 34 and ensure that the eccentric block 35 is surrounded within the cavity 361, ensuring smooth rotation of the eccentric block 35. The pressure-sensitive top shell 31 provides protection for the pressure sensor 32 and effectively transmits the load pressure to it. With the pressure sensor 32, when the pressure-sensitive massage vibrator is installed in an area with load pressure, it can detect the pressure on the corresponding part of the body in real time and feed the pressure signal back to the external massage control system. Under the control of the massage control system, the system can adjust the rotation speed and rotation time of the vibration motor 34 in real time according to the received pressure signal, thereby automatically adjusting the massage intensity of the pressure-sensitive massage vibrator based on the magnitude of the load pressure.

[0043] The cavity 361 also extends through one end of the fixed base shell 36. The motor cover 33 and the fixed base shell 36 together form a wiring hole 373 on the other side, so that the cable of the vibration motor 34 can pass through the wiring hole 373 and be connected to the power supply 4 to complete the power supply operation.

[0044] Correspondingly, the motor cover 33 is provided with an upper motor groove 331 that opens downwards, and the bottom of the cavity 361 of the fixed base shell 36 is provided with a lower motor groove 362. The upper motor groove 331 and the lower motor groove 362 together form the motor cavity 371, which is adapted to the vibration motor 34, thereby facilitating the installation of the vibration motor 34 and effectively ensuring the stability during installation.

[0045] The motor cover 33 is locked and fixed to the fixed base shell 36 by a plurality of first screws, preferably four first screws.

[0046] The pressure sensor 32 is locked to the fixed base shell 36 by a plurality of second screws. Preferably, there are four second screws. The pressure sensing top shell 31 is provided with a plurality of notches 311 for avoiding the second screws. In this way, after the pressure sensing top shell 31 is fixedly connected to the pressure sensor 32, the second screws can easily pass through the notches 311 on the pressure sensing top shell 31 to lock the pressure sensor 32 to the fixed base shell 36.

[0047] Preferably, the pressure sensor 32 is flat and has a large U-shaped groove 321 and a small U-shaped groove 322. The small U-shaped groove 322 is located inside the large U-shaped groove 321, with its open end facing the closed end of the large U-shaped groove 321. Two strain gauges 323 of the pressure sensor 32 are respectively located between the two sides of the large U-shaped groove 321 and the two sides of the small U-shaped groove 322. Furthermore, a locking block 312 is fixedly provided on the inner top surface of the pressure sensing top shell 31. The locking block 312 is locked and fixed to the small U-shaped slot 322 of the pressure sensor 32 by the third screw, and a gap 38 is formed between the pressure sensing top shell 31 and the pressure sensor 32. In this way, when pressure is applied to any position on the upper surface of the pressure sensing top shell 31, the pressure can be effectively transmitted to the area in the small U-shaped slot 322 of the pressure sensor 32 and subjected to force. As a result, the pressure sensor 32 will send a resistance change at the area of ​​the two strain gauges 323 to realize the real-time detection of pressure.

[0048] In addition, both sides of the locking block 312 are fixed with downwardly extending locking blocks 313. The two locking blocks 313 are arranged in parallel and are locked in the small U-shaped slot 322. In this way, the stability of the connection between the pressure sensing top shell 31 and the pressure sensor 32 can be further improved.

[0049] In addition, the outer surfaces of the fixed bottom shell 36 and the pressure-sensing top shell 31 are provided with noise reduction layers. Correspondingly, the noise reduction layers can be formed by covering with foam material to reduce massage noise.

[0050] Preferably, the length of the fixed bottom shell 36 and the pressure-sensing top shell 31 is no greater than 45mm, and the width of the fixed bottom shell 36 and the pressure-sensing top shell 31 is no greater than 35mm. That is, the length of the pressure-sensing massage vibrator is no greater than 45mm and the width is no greater than 35mm, so that the size of the pressure-sensing massage vibrator is appropriate for easy installation and use on a massage backpack.

[0051] In addition, the first massage vibrator 3 and the second massage vibrator 5 can also be controlled from the mobile terminal by setting up a corresponding APP.

[0052] Example 2

[0053] like Figures 12 to 13 As shown, the difference between this embodiment and Embodiment 1 is that, based on Embodiment 1, the PCB board 21 also integrates a voice recognition module 217 and a microphone 218, and the voice recognition module 217 can be an ASR voice recognition module.

[0054] like Figure 13 As shown, in standby mode, when a user issues a wake-up voice command (such as "Xiao Ai Tongxue"), voice recognition wakes the user up. When the user sends another voice command to start the massage (such as "Start Massage"), the first massage vibrator 3 and the second massage vibrator 5 are activated, and the massage begins. In massage mode, when a user issues a wake-up voice command (such as "Xiao Ai Tongxue"), voice recognition wakes the user up. When the user sends another voice command to stop the massage (such as "Stop Massage"), the first massage vibrator 3 and the second massage vibrator 5 are deactivated, and the massage stops. In massage mode, when a user issues a wake-up voice command (such as "Xiao Ai Tongxue"), voice recognition wakes the user up. When the user sends another voice command to switch massage modes... When the caller announces a sound (such as "Switch Massage Mode"), the pressure-sensitive massage backpack cycles through three massage modes: the first, second, and third. The first massage mode massages the shoulders and waist, the second massage mode massages only the shoulders, and the third massage mode massages only the waist. During the massage, pressure detection is activated, and the massage intensity of the first, second, and third massage modes can be adjusted in real time according to different load pressures. The greater the load pressure, the lower the massage intensity, and vice versa. During the massage, if no pressure is detected for 3 consecutive seconds, it is determined that the user has removed the backpack, and the massage automatically stops.

[0055] Other technical features are the same as in Embodiment 1.

[0056] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
