Technical Field

[0001] This utility model relates to the field of adjustable support technology, and in particular to external wearable devices. Background Technology

[0002] Outerwear typically refers to devices that need to be worn outside the human body (such as on the head, ears, etc.) to achieve specific functions, such as outerwear headphones. They are widely used in audio entertainment, virtual reality, professional monitoring and other fields today. Taking headphones as an example, with people's pursuit of high-quality audio experience and the continuous improvement of portability and comfort requirements, outerwear headphones have become the first choice for many consumers due to their excellent sound quality and relatively comfortable wearing method.

[0003] In existing technologies, the headband spacing adjustment of external wearable devices is mostly based on buckles or sliding mechanisms. These mechanisms are prone to wear and tear with long-term use. The buckle holes enlarge due to insertion and removal, causing the headband to loosen. The sliding parts are also prone to position changes due to wear, affecting the user experience and requiring frequent readjustment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing external wearable devices, where the headband spacing adjustment is mostly based on buckles or sliding mechanisms. These mechanisms are prone to wear and tear over time, buckle holes enlarge due to insertion and removal causing the headband to loosen, and sliding components are prone to position changes due to wear, affecting the user experience and requiring frequent readjustment. Therefore, this invention proposes an external wearable device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an external wearable device, including a top plate, an adjustment device on the outer side of the top plate, the adjustment device including a headband, the inner side of the headband being fixedly connected to the top plate, two adsorption plates being slidably connected inside the headband, an assembly base being fixedly connected to one end of each adsorption plate, a magnetic block being magnetically connected to one side of each adsorption plate, the outer sides of the two magnetic blocks being slidably connected to the headband, a connecting plate being fixedly connected to one end of each magnetic block, two telescopic rods being fixedly connected to one side of the connecting plate, a fixing block being fixedly connected to one end of each telescopic rod, and one side of each of the four fixing blocks being fixedly connected to the headband.

[0006] The effect achieved by the above components is that the connecting plate moves away from the headband, causing the magnetic block to detach from the adsorption plate and eliminating the limitation on the adsorption plate, so that the mounting base can be pulled to make the adsorption plate slide within the headband.

[0007] Preferably, the arc surface of the telescopic rod is fitted with a spring, and the two ends of the spring are fixedly connected to the connecting plate and the fixing block, respectively.

[0008] The effect achieved by the above components is that the spring-reinforced telescopic rod output end restores potential energy.

[0009] Preferably, a limiting opening is provided on one side of the headband, and a limiting block is fixedly connected to one side of the adsorption plate.

[0010] The effect achieved by the above components is that the movement of the adsorption plate causes the limiting block to slide within the limiting port.

[0011] Preferably, a pull plate is fixedly connected to the inner side of the connecting plate.

[0012] The effect achieved by the above components is to fix the pull plate to the connecting plate.

[0013] Preferably, an anti-slip pad, which is made of rubber, is fixedly connected to the outer side of the pull plate.

[0014] The effect achieved by the above components is to increase the friction of the anti-slip mat.

[0015] Preferably, the inner side of the headband is provided with a fixing device, the fixing device including a fixing plate, the outer side of the fixing plate being fixedly connected to the headband, and two magnetic plates being fixedly connected to one side of the fixing plate.

[0016] The above components achieve the following effect: the magnetic plate is fixed to the fixing plate, and the fixing plate is fixed to the headband.

[0017] Preferably, one end of the magnetic plate is magnetically connected to an adsorption block, and an assembly plate is fixedly connected to the outer side of the two adsorption blocks.

[0018] The effect achieved by the above components is that the adsorption block and the magnetic plate are attracted to each other.

[0019] Preferably, a soft pad is fixedly connected to one side of the assembly plate, and a foolproof block is fixedly connected to one side of the assembly plate.

[0020] The effect achieved by the above components is that the anti-fouling block and the soft pad are fixed on the assembly plate.

[0021] Preferably, a foolproof hole is provided on one side of the fixing plate.

[0022] The effect achieved by the above components is that the anti-foolproof hole is opened on the fixed plate.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] 1. In this utility model, by means of an adjustment device, when it is necessary to adjust the length of the headband, the connecting plate moves the magnetic block away from the adsorption plate, releasing the limit, allowing the telescopic rod to extend and the spring to stretch. Then, the mounting base is pulled to make the adsorption plate slide along the headband to adjust the length. After adjustment, the force is released, the telescopic rod and the spring retract, and the magnetic block attracts the adsorption plate to fix it. By means of an adjustment device, the problem of traditional external wearable devices having headband spacing adjustment mostly using buckles or sliding types is solved. These types are prone to wear after long-term use, buckle holes become larger due to insertion and removal, causing the headband to loosen, and sliding parts are prone to position changes due to wear, affecting the user experience and requiring frequent readjustment.

[0025] 2. In this utility model, by means of a fixing device, when the soft pad needs to be replaced, the soft pad is pulled to cause the assembly plate to move the adsorption block away from the magnetic plate and the anti-fooling block away from the anti-fooling hole, so that it can be disassembled. The reverse operation can be used to replace the new soft pad. By means of a fixing device, the problem of traditional external wearable devices, which are usually equipped with soft pads in the part that contacts the top of the head, is solved. The soft pads are usually installed by pasting or sewing, and are easy to wear and damage after long-term use, which makes it inconvenient to disassemble and replace them.

[0032] Reference Figure 1 As shown, this utility model provides a technical solution: an external wearable device, including a top plate 1, an adjustment device 2 on the outer side of the top plate 1, and a fixing device 3 on the inner side of the headband 201.

[0033] The specific settings and functions of the adjustment device 2 and the fixing device 3 will be described in detail below.

[0034] Reference Figure 2 and Figure 3 As shown in this embodiment: the adjusting device 2 includes a headband 201, the inner side of which is fixedly connected to the top plate 1. Two adsorption plates 202 are slidably connected inside the headband 201. One end of each adsorption plate 202 is fixedly connected to a mounting base 207. A magnetic block 203 is magnetically connected to one side of each adsorption plate 202. The outer sides of the two magnetic blocks 203 are slidably connected to the headband 201. One end of each magnetic block 203 is fixedly connected to a connecting plate 204. Two telescopic rods 208 are fixedly connected to one side of the connecting plate 204. One end of each telescopic rod 208 is fixedly connected to a fixing block 210. One side of each fixing block 210 is fixedly connected to the headband 201. This achieves the effect of the connecting plate 204 moving away from the headband 201, causing the magnetic blocks 203 to disengage from the adsorption plates 202 and eliminate their restriction. This allows the mounting base 207 to be pulled, causing the adsorption plates 202 to slide within the headband 201. A spring 209 is fitted onto the arc surface of the telescopic rod 208, with both ends of the spring 209 fixedly connected to the connecting plate 204 and the fixing block 210, respectively. This achieves the effect of the spring 209 reinforcing the output end of the telescopic rod 208 to restore potential energy. A limiting opening 211 is provided on one side of the headband 201, and a limiting block 212 is fixedly connected to one side of the adsorption plate 202. This achieves the effect of the adsorption plate 202 moving to drive the limiting block 212 to slide within the limiting opening 211. A pull plate 205 is fixedly connected to the inner side of the connecting plate 204. This achieves the effect of the pull plate 205 being fixed to the connecting plate 204. An anti-slip pad 206, made of rubber, is fixedly connected to the outer side of the pull plate 205. This achieves the effect of the anti-slip pad 206 increasing friction.

[0035] Reference Figure 4 and Figure 5 As shown in this embodiment: the fixing device 3 includes a fixing plate 31, the outer side of which is fixedly connected to the headband 201, and two magnetic suction plates 32 are fixedly connected to one side of the fixing plate 31. This achieves the effect of the magnetic suction plates 32 being fixed to the fixing plate 31, and the fixing plate 31 being fixed to the headband 201. One end of the magnetic suction plate 32 is magnetically connected to an adsorption block 33, and the outer side of the two adsorption blocks 33 is fixedly connected to an assembly plate 34. This achieves the effect of the adsorption blocks 33 attracting the magnetic suction plates 32. A soft pad 35 is fixedly connected to one side of the assembly plate 34, and a foolproof block 37 is fixedly connected to another side of the assembly plate 34. This achieves the effect of the foolproof block 37 and the soft pad 35 being fixed to the assembly plate 34. A foolproof hole 36 is provided on one side of the fixing plate 31. This achieves the effect of the foolproof hole 36 being provided on the fixing plate 31.

[0036] Working principle: When the length of the headband 201 needs to be adjusted via the adjustment device 2, the operator first pulls the anti-slip pad 206. The pulling force is transmitted to the pull plate 205, causing the connecting plate 204 to move the magnetic block 203 away from the adsorption plate 202, thereby eliminating the limitation on the adsorption plate 202. Simultaneously, the output end of the telescopic rod 208 extends, and the spring 209 is in a stretched state. After the limitation on the adsorption plate 202 is eliminated, the mounting base 207 is pulled, causing the adsorption plate 202 to slide on the headband 201, thus adjusting the length of the headband 201. After adjusting to the desired position, the force on the connecting plate 204 is released, allowing the output end of the telescopic rod 208 to engage with the spring 205. 9. Retraction: The connecting plate 204 drives the magnetic block 203 to move closer to the adsorption plate 202, so that the magnetic block 203 attracts the adsorption plate 202, thus fixing the position of the adsorption plate 202. At the same time, the movement of the adsorption plate 202 drives the limiting block 212 to slide within the limiting port 211, thereby effectively limiting the movement distance of the adsorption plate 202 and preventing it from completely detaching from the headband 201. Through the adjustment device 2, the problem of the traditional headband 201 spacing adjustment of external wearable devices, which is mostly based on buckles or sliding, is easily worn after long-term use. The buckle hole becomes larger due to insertion and removal, causing the headband 201 to loosen. The sliding parts are prone to position changes due to wear, affecting the experience and requiring frequent readjustment.

[0037] When the pad 35 needs to be replaced using the fixing device 3, the operator first pulls the pad 35, and the pulling force is transmitted to the assembly plate 34, causing the adsorption block 33 to detach from the magnetic plate 32 and the anti-fooling block 37 to detach from the anti-fooling hole 36, thus completing the disassembly of the pad 35. Then, the pad 35 to be replaced is replaced, so that the anti-fooling block 37 is aligned with the anti-fooling hole 36. The pad 35 is moved and the assembly plate drives the anti-fooling block 37 to be assembled into the anti-fooling hole 36, so that the adsorption block 33 attracts the magnetic plate 32, thus completing the installation. The fixing device 3 solves the problem that traditional external wearable devices are usually equipped with a pad 35 in the part that contacts the top of the head. The pad 35 is usually installed by pasting or sewing, and it is easy to wear and damage after long-term use, resulting in the inconvenience of disassembly and replacement.
