Description

Technical Field

[0001] This invention relates to a pressure-adjustable belt buckle that adapts to waist circumference, belonging to the field of belt buckle technology. Background Technology

[0002] As an essential accessory for securing clothing and adjusting waist size in daily wear, the core function of a belt relies on the structural design of its buckle. Currently, belt buckles on the market are mainly divided into traditional pin buckles, automatic buckles, and snap buckles. While they can meet basic waist-fixing needs, as people's demands for wearing comfort, intelligence, and convenience increase, existing technologies are gradually revealing many limitations and are difficult to adapt to the diverse usage needs in various scenarios.

[0003] Traditional pin buckle belts are secured by inserting a pin into a pre-drilled hole in the strap. Their adjustment precision is limited by the spacing between the holes, making them unsuitable for precise adjustments to slight changes in waist circumference. This can lead to issues like being too tight and constricting, or too loose and slipping. Furthermore, each adjustment requires manual removal of the pin and realignment of the hole, making the process cumbersome, especially when hands are limited (e.g., while carrying items or driving) or when waist circumference changes dynamically due to eating or exercise. While automatic buckle belts achieve quick securing through the engagement of teeth with the strap's toothed rack, their engagement structure is often purely mechanical, only locking the waist in one direction. They cannot sense or respond to pressure fluctuations caused by changes in waist circumference. When the user's waist increases (e.g., after a meal), the belt applies constant pressure, causing discomfort and potentially affecting blood circulation. Conversely, when the waist decreases, the strap can easily loosen or shift due to gaps in the tooth engagement, losing its securing effect. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a self-adjusting belt buckle with adaptive waist circumference.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An adaptive waistband pressure self-adjusting belt buckle includes a mounting base, a buckle plate on the upper side of the mounting base, a cover plate on the upper side of the buckle plate, a belt connecting assembly on one side of the mounting base, a belt component inside the belt connecting assembly, one end of the belt component passing between the buckle plate and the cover plate, an automatic adjustment unit for adaptive waistband on the inner side of the mounting base, the automatic adjustment unit including a mode adjustment selection component, a drive component, and a rechargeable power supply component, and an indicator light fitted on one side of the mounting base.

[0007] Through the above technical solution, the mounting base serves as a support, and the buckle plate and cover plate cooperate to form a channel for belt insertion and limiting. The belt connecting component is used to fix one end of the belt component. After the other end of the belt component passes through the gap between the buckle plate and the cover plate, it is linked with the automatic adjustment unit inside the mounting base. The automatic adjustment unit integrates the mode adjustment selection component, the drive component, and the rechargeable power supply component. The mode adjustment selection component allows for manual or electric adjustment selection. The rechargeable power supply component provides power to the entire device. The drive component responds to the electric adjustment command of the mode adjustment selection component, driving the belt component to extend and retract, ultimately achieving adaptive pressure adjustment of the waist circumference.

[0008] Preferably, the belt connecting assembly includes a connector, which is disposed on one side of the mounting base. A connecting shaft is rotatably sleeved on the inner side of the connector, and a housing is sleeved on the outer side of the connecting shaft. A connecting shaft is rotatably connected on the inner side of the housing, and a toothed retainer is sleeved on the outer side of the connecting shaft. A groove is provided on the lower side of the housing near the mounting base.

[0009] Through the above technical solution, the connector is connected to one side of the mounting base to provide support for the entire component; the first connecting shaft passes through the inside of the connector, and the housing drives the connector to rotate around the first connecting shaft; the second connecting shaft is installed inside the housing, and the toothed clamp rotates around the second connecting shaft, and the toothed structure engages with the end of the belt strap to limit the movement; a groove is opened on the lower side of the housing near the mounting base to facilitate manual opening of the housing.

[0010] Preferably, the mode adjustment selection component includes a circuit board, which is disposed inside the mounting base. Two buttons are electrically connected to one side of the circuit board. The two buttons are located on one side of the mounting base, and are respectively a manual adjustment button and an electric adjustment button. The indicator light is electrically connected to the circuit board.

[0011] With the above technical solution, the circuit board is installed inside the mounting base and serves as the core carrier for circuit control. The buttons are electrically connected to the circuit board and exposed on one side of the mounting base. Depending on the button selection, manual or electric adjustment can be selected, and the indicator light can display the power status.

[0012] Preferably, the drive assembly includes a motor, which is disposed in the inner middle of the mounting base. The output end of the motor is provided with a limit transmission component. A pressure sensor is provided between the connector and the mounting base. A tactile switch is electrically connected to one side of the circuit board. The tactile switch is disposed through one side of the buckle plate.

[0013] With the above technical solution, the motor is fixed in the middle of the inner side of the mounting base, and the output end is connected to the limiting transmission component. The pressure sensor is set between the connector and the mounting base to detect the pressure value of the belt on the waist in real time and transmit the signal to the circuit board. The tactile switch is electrically connected to the circuit board, and one end passes through the buckle plate. When the cover plate is closed, the tactile switch is squeezed to trigger the drive component. When the pressure value detected by the pressure sensor exceeds the preset range, the circuit board receives the signal and controls the motor to start. The motor drives the limiting transmission component to rotate. The limiting transmission component meshes with the toothed belt of the belt component, thereby pulling the toothed belt to adjust the belt length.

[0014] Preferably, the rechargeable power supply component includes a battery, which is disposed inside the mounting base and electrically connected to the circuit board. A Type-C charging component is electrically connected to one side of the battery, and one side of the Type-C charging component is disposed through one side of the mounting base.

[0015] With the above technical solution, the battery is installed inside the mounting base and electrically connected to the circuit board to provide power to the entire automatic adjustment unit; the Type-C charging component is electrically connected to the battery and exposed on one side of the mounting base, and can be connected to an external power source to charge the battery through the Type-C interface to achieve cyclic replenishment of power.

[0016] Preferably, a magnetic strip is fitted into one side of the buckle plate, the cover plate is made of metal, and the magnetic strip is used to limit the cover plate in the absence of external force.

[0017] With the above technical solution, the magnetic strip is embedded on one side of the buckle plate, and the cover plate is made of metal components. When the cover plate is closed, the cover plate and the buckle plate are magnetically attracted by the magnetic strip, so as to achieve the limiting and fixing without external force.

[0018] Preferably, a spring clip is provided on one side of the buckle plate, which is used to limit the connection between the cover plate and the buckle plate, thereby limiting the opening angle of the cover plate.

[0019] With the above technical solution, the spring clip is located on one side of the cover plate. When the cover plate is opened, the spring clip undergoes elastic deformation, generating a reverse elastic force to limit the rotation angle of the cover plate. When the cover plate is closed, the spring clip returns to its original shape, helping the cover plate maintain a stable closed state.

[0020] Preferably, the belt component includes a strap and a toothed belt. The tail end of the strap is connected to the housing and limited by a toothed clamp. The toothed belt is fitted onto one side of the strap, and the toothed grooves of the toothed belt match the limiting transmission component.

[0021] Through the above technical solution, the belt component consists of a strap and a toothed belt. The end of the strap is connected to the housing and is fixed by the toothed clamp. The toothed belt is fitted into one side of the strap, and its toothed structure matches the limiting transmission component of the drive component. When the limiting transmission component rotates, it drives the toothed belt to move through the toothed engagement, thereby realizing the adjustment of the belt length.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention features a pressure sensor with real-time monitoring capabilities, enabling the device to automatically adjust belt tension based on changes in waist pressure. This solves the problem of frequent manual adjustments required with traditional belts, achieving adaptive fit to waist circumference. The meshing transmission method between the limit transmission component and the toothed belt ensures high transmission accuracy and a smooth, uninterrupted adjustment process, preventing waist pressure caused by excessive adjustment. The touch switch is linked to the cover plate, providing dual protection against accidental activation when the cover plate is not closed, thus enhancing safety.

[0024] This invention uses a rechargeable power supply method, which is more energy-efficient and environmentally friendly than disposable batteries, reducing user costs. The Type-C interface is a universal charging interface, allowing users to charge it with common devices such as mobile phone chargers, which enhances compatibility and improves the portability of the device.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-8 The present invention provides a technical solution:

[0037] An adaptive waistband pressure self-adjusting belt buckle includes a mounting base 1. A buckle plate 2 is screwed to the upper side of the mounting base 1, forming a receiving space between the buckle plate 2 and the mounting base 1 for accommodating some components of an automatic adjustment unit. A cover plate 4 is movably connected to the upper side of the buckle plate 2. A belt connecting assembly 3 is connected to one side of the mounting base 1. A belt component 5 is provided inside the belt connecting assembly 3. One end of the belt component 5 passes through the gap between the buckle plate 2 and the cover plate 4 and extends to the inside of the mounting base 1, where it is linked with the automatic adjustment unit. An automatic adjustment unit for adaptive waistband is provided inside the mounting base 1. The automatic adjustment unit includes a mode adjustment selection component, a drive component, and a rechargeable power supply component, which are electrically connected to form a complete control and power output circuit.

[0038] The belt connection assembly 3 includes a connector 31, which is connected to one side wall of the mounting base 1. The inner side of the connector 31 is symmetrically provided with shaft holes, and a connecting shaft 32 is rotatably sleeved in the shaft hole. A housing 33 is interference-fitted to the outer side of the connecting shaft 32, so that the housing 33 can rotate around the connecting shaft 32 to adapt to the angle changes when the belt is worn.

[0039] Another set of shaft holes is symmetrically opened on the inner side of the housing 33. A connecting shaft 34 is rotatably connected in the shaft hole. A toothed clip 35 is sleeved on the outer side of the connecting shaft 34. Triangular teeth are evenly distributed on the outer side of the toothed clip 35 for engaging and limiting the end of the belt 5. A groove 36 is opened on the lower side of the housing 33 near the mounting base 1.

[0040] The mode adjustment selection component includes a circuit board 9, which is connected to the inner bottom of the mounting base 1 via a slot and a clip. Two buttons 11 are electrically connected to one side of the circuit board 9. The two buttons 11 are located in the mounting holes opened on one side wall of the mounting base. The two buttons are a manual adjustment button and an electric adjustment button, respectively. Manual or electric adjustment can be selected according to the usage requirements. An indicator light 16 is electrically connected to the circuit board 9.

[0041] The drive assembly includes a motor 6, which is fixed to the inner center of the mounting base 1. The output end of the motor 6 is connected to a limit transmission component 7, which matches the tooth groove of the belt component 5. A pressure sensor 8 is provided in the gap between the connector 31 and the mounting base 1. The pressure sensor 8 is electrically connected to the signal receiving module on the circuit board 9 through a wire to detect the pressure value generated when the belt is pulled in real time and convert the pressure signal into an electrical signal and transmit it to the circuit board 9.

[0042] One side of the circuit board 9 is electrically connected to a tactile switch 10 via a wire. The tactile switch 10 is installed through one side wall of the cover plate 2. When the cover plate 4 is closed, the side wall of the cover plate 4 presses the trigger end of the tactile switch 10, causing the tactile switch 10 to be in the triggered state. At this time, the circuit board 9 can control the motor 6 to start. When the cover plate 4 is opened, the trigger end of the tactile switch 10 is reset, and the circuit board 9 controls the motor 6 to stop working, which plays a role in preventing accidental touch.

[0043] The rechargeable power supply assembly includes a battery 12, which is a micro rechargeable lithium battery. The battery 12 is fixed to the inside of the mounting base 1 via a battery bracket. The positive and negative terminals of the battery 12 are electrically connected to the power interface of the circuit board 9 via wires, providing a stable DC power supply to the entire automatic adjustment unit. A Type-C charging component 13 is electrically connected to one side of the battery 12 via wires. The Type-C charging component 13 is installed through-hole in one side wall of the mounting base 1, with its interface facing outwards, facilitating charging of the battery 12 by the user via an external power source connected to a Type-C data cable. Simultaneously, the Type-C charging component 13 has a built-in overcharge and over-discharge protection module, effectively extending the lifespan of the battery 12.

[0044] A magnetic strip 14 is fitted into one side of the buckle 2. The magnetic strip 14 is a permanent magnet, and its outer side is flush with the side wall of the buckle 2. The cover plate 4 is made of iron alloy. When the cover plate 4 is closed, under the magnetic attraction of the magnetic strip 14, the cover plate 4 can be fixed to the buckle 2 without external force, preventing the cover plate 4 from being accidentally opened during wearing.

[0045] One side of the buckle plate 2 is fixed with a spring piece 15 by rivets. The spring piece 15 is made of elastic steel sheet. One end of it is fixedly connected to the buckle plate 2, and the other end extends to the rotation trajectory of the cover plate 4. When the cover plate 4 is opened, the side wall of the cover plate 4 squeezes the spring piece 15, causing the spring piece 15 to undergo elastic deformation and generate a reverse elastic force, thereby limiting the opening angle of the cover plate 4 and preventing the cover plate 4 from being over-opened and causing collision damage with other components.

[0046] The belt component 5 includes a strap 51 and a toothed belt 52. The strap 51 is made of wear-resistant leather to ensure wearing comfort. The end of the strap 51 extends into the housing 33 and is engaged and limited by the toothed structure of the toothed clip 35. Users can remove and replace the strap 51 by rotating the toothed clip 35.

[0047] The toothed belt 52 is made of hard rubber and has evenly spaced toothed grooves on its outer side. The toothed belt 52 is attached to one side of the strap 51 by adhesive bonding. The toothed grooves of the toothed belt 52 match the teeth of the limiting transmission component 7. When the limiting transmission component 7 rotates, the toothed belt 52 can be moved through the toothed groove engagement, thereby adjusting the belt length.

[0048] The workflow of this embodiment is as follows:

[0049] When wearing the belt, the user first secures the end of the strap 51 inside the belt connecting assembly 3, then passes the other end of the belt 5 through the gap between the buckle plate 2 and the cover plate 4. After closing the cover plate 4, the touch switch 10 is triggered. The user can select manual or electric adjustment according to the button 11. During electric adjustment, the pressure sensor 8 detects the pressure value of the belt on the waist in real time and transmits it to the circuit board 9. When the pressure value exceeds the preset threshold, the circuit board 9 controls the motor 6 to start. The motor 6 drives the limit transmission component 7 to rotate, pulling the toothed belt 52 to loosen the belt. When the pressure value is lower than the preset threshold, the motor 6 rotates in the opposite direction, pulling the toothed belt 52 to tighten the belt, ultimately achieving adaptive pressure adjustment of the waist.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
