Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment parts, in particular to a cover structure of a wearable device. Background Art

[0002] Wearable devices are small, easier to carry, and closer to the human body. Among many wearable devices, most users prefer to wear wristband products.

[0003] In actual use, wearable smart watches usually need to be equipped with a protective cover to protect key parts such as the display screen and internal precision components. This protective cover can prevent the core components of the watch from being directly damaged when accidentally colliding, falling, or coming into contact with sharp objects.

[0004] However, most existing protective covers are installed on wearable smart watches in a fixed manner, which means that the connection between the case and the internal structure of the watch is relatively rigid. When scratched by external force, there is no buffer space or structure to disperse and absorb the impact force. All external forces act directly on the surface of the case, so that the scratching force can be completely transmitted to the case material, which easily causes surface scratches and cannot be effectively protected. Utility Model Content

[0005] The purpose of the present invention is to provide a cover structure for a wearable device to solve the problem in the above-mentioned background technology that external force directly acts on the surface of the case, which easily causes scratches on the surface.

[0006] In order to solve the above technical problems, the present invention provides a cover structure of a wearable device, including a watch base, on which a watch cover is detachably mounted, and the watch cover includes:

[0007] The outer cover is provided on the meter base and can slide vertically along the meter base. The bottom surface of the outer cover is provided with a sleeve extending toward the meter base. A piston rod is slidably installed inside the sleeve. The bottom end of the piston rod is fixed to the side wall of the meter base.

[0008] An inner cover is arranged on the inner ring of the outer cover and can slide radially along the inner ring of the outer cover, and a glass cover is fixedly installed on the inner ring of the inner cover;

[0009] The annular airbag is fixedly arranged on the outer ring of the inner cover. The annular airbag is provided with a gas hose connected to the inner cavity of the sleeve. When the inner cover slides along the table seat, the internal gas of the annular airbag is transported to the inside of the sleeve through the gas hose.

[0010] Furthermore, the piston rod includes a cylinder and a disc body, the cylinder can slide along the axial direction of the sleeve, the disc body is installed at one end of the piston rod, and the disc body is slidably connected to the inside of the sleeve, and the end of the air hose connected to the sleeve is located at the lower part of the disc body.

[0011] Furthermore, a convex edge is radially extended on the outer ring side wall of the inner cover, and a guide groove is radially extended on the inner ring side wall of the outer cover, and the convex edge is slidably connected to the inside of the guide groove.

[0012] Furthermore, a positioning block is fixedly installed at the bottom end of the piston rod, and an annular mounting groove for inserting the positioning block is opened on the table base. A positioning bolt is threadedly connected on the side wall of the table base, and one end of the positioning bolt extends to the inside of the annular mounting groove and is threadedly connected to the positioning block.

[0013] Furthermore, a sealing belt is fixedly connected to the outer ring side wall of the inner cover, and the side of the sealing belt away from the inner cover is fixedly connected to the inner ring side wall of the outer cover.

[0014] Furthermore, four sleeves are provided, and the four sleeves are distributed in a circular array on the inner wall of the outer cover. The number of the piston rods, positioning blocks, positioning bolts and gas hoses is the same as that of the sleeves.

[0015] Furthermore, an annular receiving groove is formed on the inner ring of the inner cover, and the glass cover is installed inside the annular receiving groove. The thickness of the glass cover is adapted to the depth of the annular receiving groove.

[0016] Furthermore, a sealing gasket is fixedly installed on the inner side wall of the annular accommodating groove, and the material of the sealing gasket is rubber.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The utility model fixes the glass cover on the watch base by cooperating with the outer cover and the inner cover. The outer cover can be vertically displaced along the watch base, and the inner cover can be horizontally displaced along the outer cover, thereby achieving the effect of the glass cover being movably mounted on the watch base. When the glass cover faces the risk of possible scratches, it can avoid scratches and provide protection.

[0019] 2. In the present invention, during the displacement of the inner cover, the annular airbag provided on its outer wall will be squeezed against the inner wall of the watch base. Since the annular airbag is filled with gas, when the annular airbag is squeezed, the gas can enter the interior of the sleeve from the gas hose. The gas can play a certain buffering effect during the flow process, thus providing a certain degree of protection. As the gas enters, the sleeve will shrink toward the inside of the watch base. The shrinkage of the sleeve will drive the outer cover to move downward, thereby causing the glass cover to move toward the inside of the watch base to avoid it, further providing a protective effect.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 5 The utility model provides a technical solution: a cover structure of a wearable device, comprising a watch base 1, on which a watch cover is detachably mounted, the watch cover comprising:

[0028] The outer cover 2 is provided on the meter base 1 and can slide vertically along the meter base 1. The bottom surface of the outer cover 2 is provided with a sleeve 11 extending toward the meter base 1. A piston rod 12 is slidably mounted inside the sleeve 11. The bottom end of the piston rod 12 is fixed to the side wall of the meter base 1.

[0029] The inner cover 3 is arranged on the inner ring of the outer cover 2 and can slide radially along the inner ring of the outer cover 2. The inner ring of the inner cover 3 is fixedly mounted with a glass cover 4;

[0030] The annular airbag 6 is fixedly arranged on the outer ring of the inner cover 3. A gas hose 15 is provided on the annular airbag 6 to communicate with the inner cavity of the sleeve 11. When the inner cover 3 slides along the table base 1, the internal gas of the annular airbag 6 is transported to the inside of the sleeve 11 through the gas hose 15.

[0031] Specifically, when the glass cover 4 of the device is scratched or rubbed during use, the glass cover 4 will drive the inner cover 3 to move as a whole due to the influence of the force. During the displacement of the inner cover 3, the annular airbag 6 provided on its outer wall will be squeezed with the inner wall of the watch base 1. Since the inside of the annular airbag 6 is filled with gas, when the annular airbag 6 is squeezed, the gas can enter the inside of the sleeve 11 from the gas hose 15, and the gas can play a certain buffering effect during the flow process, playing a certain role in protection, and as the gas enters the sleeve 11, it will shrink toward the inside of the watch base 1. The shrinkage of the sleeve 11 will drive the outer cover 2 to move downward, thereby causing the glass cover 4 to move toward the inside of the watch base 1 to avoid it, further playing a protective role.

[0032] It should be noted that the inner wall of the sleeve 11 has been specially smoothed to ensure smooth sliding of the piston rod 12 inside it, reduce jamming caused by friction, and enable the outer cover 2 to quickly and sensitively perform vertical sliding movements when triggered by external force.

[0033] A high-precision micro-ball bearing structure is installed at the contact point between the inner cover 3 and the outer cover 2. This allows the inner cover 3 to slide smoothly and quickly along a predetermined radial path when subjected to external forces transmitted by the glass cover 4, accurately triggering subsequent protective actions. Furthermore, the inner cover 3 is constructed of a high-strength yet lightweight alloy material, ensuring structural stability without adding excessive weight to the wearable device.

[0034] The annular airbag 6 is made of a special wear-resistant rubber material with high elastic recovery properties, capable of withstanding repeated compression and recovery without degradation. The gas hose 15 is made of a material with excellent flexibility and sealing properties, ensuring that gas does not leak during transmission and can adapt to the various changes in shape caused by the movement of the outer cover 2 and inner cover 3.

[0035] In addition, when the external force disappears, it is also equipped with an automatic reset device, which can use the elastic elements or gas pressure difference inside the annular airbag 6 to automatically restore the outer cover 2 and the inner cover 3 to their initial positions, so that the glass cover 4 returns to normal use state, and is also prepared for the next possible protective action.

[0036] See Figure 1 The piston rod 12 includes a cylinder and a disc. The cylinder can slide axially along the sleeve 11. The disc is installed at one end of the piston rod 12 and is slidably connected to the inside of the sleeve 11. The end of the air hose 15 connected to the sleeve 11 is located at the lower part of the disc.

[0037] Specifically, gas is delivered to the interior of the sleeve 11 through the gas hose 15. When the gas enters the lower part of the disc body, the gas pushes the sleeve 11 downward, and the outer cover 2 can be driven to move downward during the downward movement of the sleeve 11.

[0038] See Figure 3 , The outer ring side wall of the inner cover 3 is provided with a radially extending convex edge 8, the inner ring side wall of the outer cover 2 is provided with a radially extending guide groove 7, the convex edge 8 is slidably connected to the inside of the guide groove 7.

[0039] Specifically, the guide groove 7 and the convex edge 8 cooperate to guide the sliding of the inner cover 3, thereby improving the sliding stability of the inner cover 3.

[0040] See Figure 3 A positioning block 13 is fixedly installed at the bottom end of the piston rod 12, and an annular mounting groove 10 is provided on the meter base 1 for inserting the positioning block 13. A positioning bolt 14 is threadedly connected to the side wall of the meter base 1, and one end of the positioning bolt 14 extends to the inside of the annular mounting groove 10 and is threadedly connected to the positioning block 13.

[0041] Specifically, the piston rod 12 can be fixed on the meter base 1 by cooperating with the provided annular mounting groove 10 , the positioning block 13 and the positioning bolt 14 .

[0042] See Figure 1 、 Figure 3 and Figure 4 A sealing belt 5 is fixedly connected to the outer ring side wall of the inner cover 3 , and the side of the sealing belt 5 away from the inner cover 3 is fixedly connected to the inner ring side wall of the outer cover 2 .

[0043] Specifically, the sealing tape 5 is provided to connect the gap between the inner cover 3 and the outer cover 2, thereby improving the aesthetics of the overall connection between the outer cover 2 and the inner cover 3, and at the same time preventing the gap between the inner cover 3 and the outer cover 2 from pinching the wearer's skin during the sliding process of the inner cover 3 relative to the outer cover 2.

[0044] See Figure 2-Figure 3 There are four sleeves 11 , which are distributed in a circular array on the inner wall of the outer cover 2 . The number of piston rods 12 , positioning blocks 13 , positioning bolts 14 and gas hoses 15 is the same as that of the sleeves 11 .

[0045] Specifically, the four sleeves 11 , the piston rod 12 , the positioning block 13 , the positioning bolt 14 and the gas hose 15 cooperate to improve the stability of the connection between the outer cover 2 and the meter base 1 .

[0046] See Figure 3 , the inner ring of the inner cover 3 is provided with an annular receiving groove 9, the glass cover 4 is mounted inside the annular receiving groove 9, the thickness of the glass cover 4 and the depth of the annular receiving groove 9 are adapted.

[0047] Specifically, the annular receiving groove 9 is provided to facilitate the installation of the glass cover 4 and, at the same time, to improve the stability of the glass cover 4 when installed on the inner cover 3 .

[0048] See Figure 3 A sealing gasket is fixedly installed on the inner wall of the annular accommodating groove 9, and the material of the sealing gasket is rubber.

[0049] Specifically, the sealing gasket is provided to improve the overall sealing performance of the annular receiving groove 9, thereby effectively preventing external dust and sewage from penetrating into the interior of the watch base 1 from the connection between the glass cover 4 and the inner cover 3, thereby improving the overall sealing performance of the device.

[0050] Working principle: During use, the watch strap needs to be connected to the watch base 1, and then the watch base 1 is worn on the user's wrist. When the glass cover 4 is scratched or rubbed during use, the glass cover 4 will drive the inner cover 3 to move as a whole under the influence of force. During the displacement of the inner cover 3, the annular airbag 6 set on its outer wall will be squeezed with the inner wall of the watch base 1. Since the inside of the annular airbag 6 is filled with gas, when the annular airbag 6 is squeezed, the gas can enter the inside of the sleeve 11 from the gas hose 15, and the gas can play a certain buffering effect during the flow process, playing a certain role in protection, and as the gas enters the sleeve 11, it will shrink toward the inside of the watch base 1. The shrinkage of the sleeve 11 will drive the outer cover 2 to move downward, thereby causing the glass cover 4 to move toward the inside of the watch base 1 to avoid it, further playing a protective role.
