[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0031] See also Figure 1 The present invention provides a protective shell, comprising a first shell 10, a second shell 20 and a snap-on structure. The protective shell is used to protect a product, which may be a mobile device, such as a mobile phone, a tablet computer, etc. Taking a mobile phone as an example, the first shell 10 can be used to protect the display screen of the mobile phone or the edge of the upper shell of the mobile phone where the display screen is located. In this case, the first shell 10 can be frame-shaped, or the area of ​​the first shell 10 corresponding to the display screen can be made of a light-transmitting material, and the second shell 20 can be used to protect the bottom shell of the mobile phone. In the assembled state, the first shell 10 is located above the second shell 20. In the following embodiments, the direction where the first shell 10 is located is regarded as the upper direction, and the direction where the second shell 20 is located is regarded as the lower direction.

[0032] See also Figure 2 and Figure 3The first shell 10 includes a panel 11 and a slider 32 protruding from the panel 11. The protrusion 421 is specifically protruding from the lower surface of the panel 11. The slider 32 has a first inclined surface 321, and the first inclined surface 321 is located on the lower surface of the slider 32.

[0033] The first housing 10 is slidably connected to the second housing 20 and can slide from a first position to a second position. When the first housing 10 moves to the second position, the first clamping member 41 and the second clamping member 42 are covered.

[0034] See also Figure 3 The second housing 20 defines a sliding channel 301 extending obliquely downward from an opening. The sliding channel 301 has a second inclined surface 311 that matches the first inclined surface 321. It is understood that the opening of the sliding channel 301 is located above the sliding channel 301 and directly opposite the upper extension of the sliding channel 301, while the lower extension of the sliding channel 301, which extends obliquely downward, is away from the opening.

[0035] The slider 32 is slidably connected to the sliding channel 301. The second inclined surface 311 abuts against the first inclined surface 321. As the slider 32 slides from the opening toward the extended end of the sliding channel 301, the panel 11 moves toward the second housing 20. The sliding channel 301 prevents the first inclined surface 321 from separating from the second inclined surface 311. When the slider 32 moves to the lower extended end of the sliding channel 301, the first housing 10 moves to the second position.

[0036] When assembling this protective case, first place the product on the second shell 20. Then, insert the slider 32 into the sliding channel 301 through the opening of the sliding channel 301, aligning the first inclined surface 321 with the second inclined surface 311. Then, push the slider 32 along the extension direction of the sliding channel 301, so that the slider 32 drives the first shell 10 to slide downward at an angle until the first shell 10 and the second shell 20 jointly clamp the product. The first shell 10 is slidably connected to the second shell 20 via the sliding channel 301 that extends downward at an angle. When the first shell 10 moves toward the second shell 20, it slides downward at an angle. This prevents the first shell 10 from scratching the product surface when sliding horizontally relative to the second shell 20, thereby improving the user experience.

[0037] See also Figure 3The second housing 20 defines a sliding groove 312. The sliding groove 312 has a first groove wall and a second groove wall facing each other along its extension direction. A stopper 31 protrudes from the groove wall of the sliding groove 312. The stopper 31 is spaced from the groove wall of the first groove wall and forms an opening. The stopper 31 is spaced from the groove bottom surface of the sliding groove 312 and forms a sliding channel 301. The sliding channel 301 extends from the first groove wall to the second groove wall. The groove bottom surface of the sliding groove 312 has a second inclined surface 311. In other words, the sliding groove 312 extends from the first groove wall to the second groove wall. In this case, the first groove wall is the upper extension of the sliding channel 301, and the second groove wall is the lower extension of the sliding channel 301. The horizontal height of the first groove wall is higher than that of the second groove wall. The stopper 31 can be protruded from the groove wall between the first and second groove walls, or it can be protruded from the second groove wall. The extension direction of the limit block 31 can be parallel to the second inclined surface 311 to form a sliding channel 301 of equal height. Optionally, the entire bottom surface of the sliding groove 312 is the second inclined surface 311 to facilitate guiding the slider 32. Optionally, the limit block 31 can be elastically deformed, that is, the limit block 31 can withstand a certain amount of elastic deformation. In this way, when the slider 32 slides into the sliding channel 301, if the first shell 10 slightly deviates from the preset track, the limit block 31 can cushion the first shell 10 through elastic deformation to prevent the slider 32 from breaking. The limit block 31 can be spaced apart from other groove walls to increase the elastic deformation range that can be tolerated. In this case, the limit block 31 can form the sliding channel 301 together with the bottom of the sliding groove 312 and can limit the upward movement of the slider 32. In other embodiments, the limit block 31 can also be connected to other groove walls.

[0038] Specifically, the slider 32 includes a connector protruding from the panel 11 and a sliding member connected to the connector and spaced apart from the panel 11. The sliding member has a first inclined surface 321. The sliding member is adapted to fit within the sliding channel 301 to prevent shaking during sliding. The arrangement of the connector allows the sliding member to extend into the sliding channel 301 while avoiding the stop block 31.

[0039] In this embodiment, the second housing 20 has a connecting surface 203, a first end surface, and a second end surface. The connecting surface 203 is opposite the first housing 10 and is connected to the first and second end surfaces. The connecting surface 203 is used to support the product. The first and second end surfaces are opposite each other and can be parallel to each other. The first housing 10 can move toward the second housing 20 from the first end surface to the second end surface. At this time, a receiving cavity for placing the product is formed between the first and second housings 10, 20. Specifically, the second housing 20 includes a base plate 21 and a connecting edge 22 connected to the base plate 21. The base plate 21 has a connecting surface 203, a first end surface, and a second end surface. The connecting edge 22 is protruding from the connecting surface 203. There are two connecting edges 22, which are arranged on opposite edges of the base plate 21 and are parallel and spaced apart. Both connecting edges 22 extend from the first end surface to the second end surface and are used to protect the left and right sides of the product.

[0040] The distance between the end of the second inclined surface 311 close to the first groove wall and the connecting surface 203 is greater than the distance between the end of the second inclined surface 311 close to the second groove wall and the connecting surface 203. That is, the sliding channel 301 is higher than the connecting surface 203, and the horizontal height of the first groove wall is higher than the horizontal height of the second groove wall, so that the sliding channel 301 extends obliquely downward from the first groove wall toward the second groove wall.

[0041] The connecting edge 22 is provided with a sliding groove 312 toward the connecting surface 203. That is to say, the notch of the sliding groove 312 faces upward so as to form an opening of the sliding channel 301 together with the limiting block 31.

[0042] The two connecting edges 22 and the bottom plate 21 together form a receiving cavity for placing products. Each connecting edge 22 is provided with a sliding groove 312. The sliding grooves 312 on the two connecting edges 22 can be arranged in a mirror image to facilitate simultaneous sliding connection of multiple sliders 32 and the sliding channel 301.

[0043] Optionally, the groove wall of the sliding groove 312 close to the accommodating cavity passes through the accommodating cavity. At this time, the sliding member can protrude from the outside of the connecting member, and the connecting member can slide along the edge of the limit block 31 to facilitate rapid docking of the slider 32 and the sliding channel 301.

[0044] Each connecting edge 22 is provided with a plurality of sliding channels 301 , which are arranged at intervals along the extending direction of the connecting edge 22 . The number of sliders 32 is the same as the number of sliding channels 301 , and each sliding channel 301 corresponds to a slider 32 .

[0045] The first shell 10 has a first inclined sliding surface, the slider 32 is connected to the first inclined sliding surface, the first inclined sliding surface is parallel to the first inclined surface 321, the second shell 20 has a second inclined sliding surface adapted to the first inclined sliding surface, the sliding groove 312 is opened on the second inclined sliding surface, the second inclined sliding surface is parallel to the second inclined surface 311, when the slider 32 slides from the opening toward the extension end of the sliding channel 301, the first inclined sliding surface can fit into the second inclined sliding surface.

[0046] See also Figure 2 and Figure 5 The clamping structure includes a first clamping member 41 connected to the first shell 10, a second clamping member 42 slidably connected to the second shell 20, and a reset member 43 connected to the second shell 20. The second clamping member 42 can slide between an initial position and an avoidance position. The sliding direction of the second clamping member 42 is perpendicular to the movement direction of the first shell 10 relative to the second shell 20. There is a magnetic repulsive force between the reset member 43 and the second clamping member 42. Specifically, the second clamping member 42 and the reset member 43 can both be magnetic members, or be connected to magnetic members. The magnetism of the reset member 43 facing the second clamping member 42 is opposite to the magnetism of the second clamping member 42 facing the reset member 43. When the first housing 10 moves toward the second housing 20, the first latching member 41 pushes the second latching member 42 to slide from its initial position toward its avoidance position. At this time, the return member 43 can apply a magnetic repulsive force to the first latching member 41 toward its initial position. This causes the return member 43 to push the second latching member 42 back to its initial position when the first latching member 41 moves to the locking position, thereby engaging with the first latching member 41. When the first latching member 41 and the second latching member 42 are engaged, the first housing 10 can move directly above the second housing 20.

[0047] When the protective case is in use, a product can be placed between the first shell 10 and the second shell 20. When the first shell 10 and the second shell 20 are engaged, the product is protected. The first shell 10 and the second shell 20 of the protective case are engaged by the engagement of the first clip 41 and the second clip 42. The second clip 42 is slidably connected to the second shell 20. When the first shell 10 moves toward the second shell 20, the first clip 41 pushes the second clip 42 from the initial position to the avoidance position. At this time, the reset member 43 provides a restoring force to the second clip 42 to slide toward the initial position through the magnetic repulsion between the reset member 43 and the second clip 42. The first clip 41 continues to move to the engaged position. At this time, the second clip 42 returns to the initial position under the action of the magnetic repulsion of the reset member 43. When the first clip 41 is in the engaged position and the second clip 42 is in the initial position, the first clip 41 and the second clip 42 are engaged. In this way, the protective shell realizes the snap-fitting between the first snap-fitting part 41 and the second snap-fitting part 42 through magnetic repulsion without elastic deformation, thereby extending the service life of the snap-fitting structure and improving the user experience.

[0048] See also Figure 2 and Figure 4 The first housing 10 further includes a fastening member 12. The panel 11 has a first end and a second end. The first end corresponds to the first end surface of the second housing 20, and the second end corresponds to the second end surface of the second housing 20. The fastening member 12 is connected to the first end of the panel 11. The first clip 41 is connected to the fastening member 12 and extends toward the second end. The first clip 41 is spaced apart from the panel 11. When the first clip 41 and the second clip 42 are fastened together, the panel 11 is spaced apart from the bottom plate 21 and connected to the connecting edge 22. The fastening member 12 is used to connect to the first clip 41 and also protect the edge of the product.

[0049] In this example, see Figure 2 and Figure 5 The second housing 20 has a sliding groove 201, into which the second clip 42 is slidably connected. The sliding groove 201 is used to guide the sliding trajectory of the second clip 42. The two extending ends of the sliding groove 201 serve as the sliding end points of the second clip 42. The second clip 42 stops sliding when it contacts the groove wall at the extending end of the sliding groove 201. The second clip 42 is provided with a protrusion 421 that fits into the sliding groove 201. It should be noted that the extension direction of the sliding groove 201 is perpendicular to the direction of movement of the first housing 10 relative to the second housing 20.

[0050] See also Figure 2 and Figure 5The first end face is provided with a receiving groove 202, the second clip 42 is located in the receiving groove 202 and can move in the receiving groove 202, the groove wall of the receiving groove 202 is provided with a sliding groove 201, and the first clip 41 can be inserted into the receiving groove 202 when moving toward the snap position. The receiving groove 202 limits the second clip 42 to prevent the second clip 42 from separating from the second shell 20. At the same time, the groove wall of the receiving groove 202 can guide and limit the first clip 41. When assembling the protective shell, the first clip 41 can be inserted into the receiving groove 202. Due to the limiting effect of the groove wall of the receiving groove 202, the first clip 41 can push the second clip 42 to move toward the avoidance position. The reset member 43 can be connected to the groove wall of the receiving groove 202.

[0051] See also Figure 2 and Figure 5 The second shell 20 includes a shell body 211 and a cover plate 212 detachably connected to the shell body 211. The shell body 211 and the cover plate 212 together form the bottom plate 21. The cover plate 212 and the receiving groove 202 together form the receiving groove 202. The cover plate 212 is provided with a sliding groove 201. Optionally, the cover plate 212 is detachably connected to the shell body 211 to facilitate the connection and removal of the second clamping member 42 from the second shell 20. The sliding groove 201 passes through the cover plate 212, so that the user can observe the movement position of the second clamping member 42 through the sliding groove 201. When the second clamping member 42 becomes stuck, the user can manually move the protrusion 421 to achieve the movement of the second clamping member 42 between the avoidance position and the initial position.

[0052] Among them, see Figure 2 and Figure 4 The first clamping member 41 is hook-shaped. In this way, when the first clamping member 41 moves to the locking position, the first clamping member 41 can hook the second clamping member 42 in the initial position, thereby achieving the clamping fit between the first clamping member 41 and the second clamping member 42.

[0053] To achieve the pushing of the first clamping member 41 on the second clamping member 42, please refer to Figure 2 The first engaging member 41 has a first guiding slope 401. When the first engaging member 41 moves toward the locking position, the first guiding slope 401 contacts the second engaging member 42 and guides the second engaging member 42 toward the avoidance position. The first guiding slope 401 can be flat or curved. The first guiding slope 401 pushes the second engaging member 42 toward the avoidance position.

[0054] Optional, see Figure 2The second clip 42 has a second guide slope 402 that mates with the first guide surface. When the first clip 41 contacts the second clip 42 and moves toward the snap-fit ​​position, the first guide slope 401 and the second guide slope 402 engage, reducing friction between the first and second clips 41, 42 and enabling rapid docking of the first and second clips 41, 42. Alternatively, the second clip 42 may be free of the second guide slope 402 and instead rely solely on the guidance of the first guide slope 401 to achieve movement toward the avoidance position.
