Detailed implementation manners

[0027] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present utility model, it is protected by the Patent Law.

[0029] This embodiment relates to a protective cover. Refer to Figure 1 - Figure 2, including: a protective cover body 100 and a bracket assembly 200. The bracket assembly 200 is disposed on the back side of the protective cover body 100, and the bracket assembly 200 is used to support the protective cover body 100 so that the protective cover is inclined at a set angle for the user to use. The bracket assembly 200 includes: a first cover body 210 and a support member 220. One end of the first cover body 210 is rotatably assembled at a position near the lower side of the back side of the protective cover body 100, and the other end thereof is a free end, which serves as a support leg to contact the ground or the tabletop during use. One end of the support member 220 is rotatably assembled on the back side of the protective cover body 100 and is located at a position above the rotating end of the first cover body 210, and the other end thereof is a free end. By adjusting the relative positions between the first cover body 210 and the support member 220, the user can select different inclination angles according to needs to adapt to different usage scenarios. When the first cover body 210 rotates and closes, the surface of the first cover body 210 close to the protective cover body 100 is the first surface 211, and the surface of the first cover body 210 facing away from the protective cover body 100 is the second surface 212. A limiting protrusion 2111 protruding upward is provided on the first surface 211, which can be used for the free end of the support member 220 to be fixedly supported to prevent accidental sliding or loosening and ensure the stability of the device during use. A relief space 213 through which the support member 220 can pass is formed in the middle of the rotating end of the first cover body 210. When the bracket assembly 200 is not in use, the free end of the support member 220 slides off the limiting protrusion 2111 and passes through the relief space 213 and falls back to the back side of the protective cover body 100. Specifically, when the user is using the device, the first cover body 210 rotates and opens, its free end abuts against the ground or the tabletop, and the free end of the support member 220 abuts against the limiting protrusion 2111 of the first cover body 210. The first cover body 210 and the support member 220 cooperate to support the protective cover body 100. However, when an external force on the first cover body 210 in the direction towards the protective cover body 100 exceeds a set force value, or an external force on the protective cover body 100 in the direction towards the first cover body 210 exceeds a set force value, or external forces on both the first cover body 210 and the protective cover body 100 in both directions exceed a set force value, the first cover body 210 is deformed, so that the free end of the support member 220 moves along the direction of the relief space 213 from the limiting protrusion 2111 and passes through the relief space 213, and the first cover body 210 rotates and falls back to the back side of the protective cover body 100, thereby avoiding damage to the first cover body 210 and the support member 220 due to excessive pressure. It realizes the advantage that the bracket assembly 200 is not easily broken when subjected to excessive external forces.

[0030] In this embodiment, referring to Figure 3, the limiting protrusion 2111 is provided with an arc-shaped guiding inclined surface 2112 on the side facing the avoidance space 213. The arc-shaped guiding inclined surface 2112 can provide a smooth transition area, making the contact between the support member 220 and the limiting protrusion 2111 smoother, reducing impact and wear. At the same time, the arc-shaped guiding inclined surface 2112 can also better guide the free end of the support member 220 to move in the correct direction, ensuring that the support member 220 can cooperate with or disengage from the limiting protrusion 2111 smoothly. When subjected to external force, the free end of the support member 220 slides off the arc-shaped guiding inclined surface 2112, avoiding excessive pressure on the first cover 210 and preventing it from breaking, and protecting the first cover 210 and the support member 220 from unnecessary damage.

[0031] In this embodiment, a plurality of limiting protrusions 2111 are provided, which can provide options for the support position. The user can adjust to the most suitable angle according to needs, improving the usage experience. Specifically, in this embodiment, two limiting protrusions 2111 are provided. Among them, the one closest to the avoidance space 213, its arc-shaped guiding inclined surface 2112 extends towards the side of the avoidance space 213 and communicates with the avoidance space 213. When subjected to external force, the free end of the support member 220 slides off the arc-shaped guiding inclined surface 2112 and passes through the avoidance space 213, and both the first cover 210 and the support member 220 rotate and fall back to the back side of the protective cover body 100. Specifically, in this embodiment, the limiting protrusion 2111 is in a long strip shape.

[0032] In this embodiment, referring to Figure 1 and Figure 3 , when both the support member 220 and the first cover 210 rotate and close, an avoidance hole 221 for the limiting protrusion 2111 to avoid is provided on the surface of the support member 220 facing the first surface 211, and the limiting protrusion 2111 is placed in the avoidance hole 221. By providing the avoidance hole 221, the limiting protrusion 2111 can avoid the support member 220 when not in use. In this way, the back side of the protective cover will not bulge due to the existence of the limiting protrusion 2111, so that the back side remains flat. At the same time, it is also convenient for storage and will not cause imbalance or shaking due to the bulge.

[0033] In this embodiment, referring to Figure 1 - Figure 2 and Figure 4, a rotating end of the first cover body 210 is provided with a rotating shaft 216 protruding outward, and the length by which the rotating shaft 216 protrudes relative to the first cover body 210 is 0.5 - 1 cm. When an external force acting on the first cover body 210 in the direction towards the protective sleeve body 100 exceeds a set force value, or an external force acting on the protective sleeve body 100 in the direction towards the first cover body 210 exceeds a set force value, or external forces acting on both the first cover body 210 and the protective sleeve body 100 in two directions exceed a set force value, the first cover body 210 deforms, such that the rotating shaft 216 of the first cover body 210 disengages from the protective sleeve body 100, the support rod rotates and falls back to the back side of the protective sleeve body 100, or the free end of the support member 220 slides down along the arc-shaped guiding inclined surface 2112 from the limiting protrusion 2111, and the first cover body 210 and the support member 220 rotate and fall back to the back side of the protective sleeve body 100, thereby avoiding damage to the first cover body 210 and the support member 220 due to excessive pressure. As a safety mechanism, it prevents the first cover body 210 and the support member 220 from being broken under pressure. By defining the protruding length of the rotating shaft 216 as 0.5 - 1 cm, it can be ensured that the rotating shaft 216 will not easily disengage under normal operating conditions, but under the action of an external force exceeding the safety value, the rotating shaft 216 can disengage in a timely manner, further protecting the first cover body 210 and the support member 220 from being damaged and broken.

[0034] In this embodiment, the bracket assembly 200 further includes: a second cover body 230 fixedly assembled on the back side of the protective sleeve body 100. Both the first cover body 210 and the support member 220 are rotatably assembled on the second cover body 230. The second cover body 230, as a fixed component, provides a rotating space for the first cover body 210 and the support member 220.

[0035] In this embodiment, referring to Figure 5 - Figure 6 , a protruding portion 214 is provided at the middle position of the free end of the first cover body 210, and a blocking groove 231 corresponding to the protruding portion 214 is provided on one side of the second cover body 230 close to the free end of the first cover body 210. When the first cover body 210 rotates and closes on the second cover body 230, the protruding portion 214 is placed into the blocking groove 231. When the first cover body 210 rotates and closes, the protruding portion 214 being placed into the blocking groove 231 enables the protective sleeve to have a locking mechanism, and a certain external force is required to open it, ensuring that the closure between the first cover body 210 and the second cover body 230 is tighter and more stable, reducing separation caused by accidental collision, and preventing the first cover body 210 from accidentally opening in the closed state. At the same time, when the protective sleeve drops or is shaken by an external force, the first cover body 210 will also tightly close on the second cover body 230.

[0036] In this embodiment, referring to Figure 5 - Figure 6, a first receiving cavity 110 for receiving the bracket assembly 200 is further provided on the back side of the protective cover body 100. A second receiving cavity 232 for receiving the support member 220 is further provided on the second cover body 230. The first receiving cavity 110 is arranged such that when the bracket assembly 200 is rotated and closed, the first cover body 210 lies flat on the back side of the protective cover body 100 without bulging. The second receiving cavity 232 is arranged such that when the support member 220 is rotated and closed, it lies flat with the second cover body 230, ensuring that the first cover body 210 also does not bulge when closed on the second cover body 230, achieving a flat surface for the protective cover. At the same time, the bracket assembly 200 can be completely stored inside the protective cover body 100 when not in use, reducing the occupied space. Specifically, in this embodiment, the first cover body 210, the second cover body 230, and the first receiving cavity 110 are all in a butterfly shape, increasing the aesthetic appeal of the protective cover and making it look more unique and beautiful. In other embodiments, the first cover body 210, the second cover body 230, and the first receiving cavity 110 may also be in other shapes.

[0037] In this embodiment, a first recess 120 is further provided on the back side of the protective cover body 100. A first tip protrusion 215 is provided in the middle of the free end of the first cover body 210. The first tip protrusion 215 facilitates opening the first cover body 210. A second recess 2321 is provided at the middle position of the second receiving cavity 232. A second tip protrusion 222 is provided on the side of the support member 220 facing the second recess 2321. The second tip protrusion 222 facilitates opening the support member 220. The design of the first tip protrusion 215 and the second tip protrusion 222 enables the user to easily grasp and open the second cover body 230 or the support member 220 with a finger, improving the operation convenience. The above settings consider the effective use of space, ensuring that the first cover body 210 and the support member 220 can fit tightly in the closed state and are also easy to open.

[0038] Specifically, in this embodiment, referring to Figure 5 - Figure 6 , a boss 217 is further provided at the rotating end of the first cover body 210. The second cover body 230 is further provided with a third recess corresponding to the boss 217. When the first cover body 210 is rotated and opened relative to the second cover body 230, the boss 217 is placed into the third recess. 233 When the first cover body 210 is opened and rotated to a certain angle, the boss 217 is placed into the third recess, which can ensure the stability of the first cover body 210 in the open state, prevent it from accidentally closing or shaking. At the same time, it limits the opening angle of the first cover body 210 to avoid excessive opening of the first cover body 210.

[0039] In this embodiment, referring to Figure 5, an anti-slip protrusion 2121 is provided at the free end position of the second surface 212. When the user opens or closes the first cover 210, the friction between the first cover 210 and the contact surface (tabletop or ground) is increased, making it not easy to slide, reducing the risk of accidental falls caused by sliding, and making it more stable. Specifically, in this embodiment, the anti-slip protrusion 2121 is an anti-slip pad made of silicone material.

[0040] The working principle of the present utility model is generally as follows: The first cover 210 rotates and opens, its free end abuts against the ground or the tabletop, and the free end of the support member 220 abuts against the limit protrusion 2111 of the first cover 210. The first cover 210 and the support member 220 cooperate to support the protective cover body 100, so that the protective cover is inclined at a set angle, meeting the user's usage requirements. When the user does not use it, the free end of the support member 220 slides off the limit protrusion 2111 and passes through the avoidance space 213 and falls back to the back side of the protective cover body 100. At the same time, the first cover 210 also closes on the back side of the protective cover body 100. However, when the external force on the first cover 210 in the direction towards the protective cover body 100 exceeds the set force value, or the external force on the protective cover body 100 in the direction towards the first cover 210 exceeds the set force value, or the first cover 210 and the protective cover body 100 are simultaneously subjected to external forces in both directions exceeding the set force value, the first cover 210 deforms, causing the free end of the support member 220 to move along the direction of the avoidance space 213 from the limit protrusion 2111 and pass through the avoidance space 213. The first cover 210 and the support member 220 rotate and fall back to the back side of the protective cover body 100, or the rotating shaft 216 is disengaged from the protective cover body 100, and the support rod rotates and falls back to the back side of the protective cover body 100. At this time, the first cover 210 falls off relative to the second cover 230 to the bottom surface or the tabletop, thus avoiding the first cover 210 and the support member 220 from being broken due to excessive pressure. It realizes the advantage that the bracket assembly 200 is not easily broken when subjected to excessive external force.

[0041] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model should be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
