The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1, a housing 100 is provided according to a preferred embodiment of the present invention. The housing 100 may be applied to electronic devices such as a mobile phone and a tablet computer.

The housing 100 includes at least a front case 10 and a slide cover 30. The front shell 10 and the sliding cover 30 are made of plastic.

Referring to fig. 2 and 3, the front housing 10 includes a first surface 101, a second surface 102 opposite to the first surface 101, and a peripheral surface 103. The circumferential surface 103 is disposed between the first surface 101 and the second surface 102 and connects the first surface 101 and the second surface 102. The peripheral surface 103 includes two oppositely disposed first side surfaces 1031, a bottom surface 1032 and a top surface 1033 disposed opposite to the bottom surface 1032. The two first side surfaces 1031, the bottom surface 1032 and the top surface 1033 are connected to each other to form the peripheral surface 103.

In this embodiment, the front housing 10 further includes two sliding slots 104. The two sliding grooves 104 are respectively disposed on the two first side surfaces 1031, and are respectively formed by the bottom surface 1032 extending toward the top surface 1033. The slide groove 104 is recessed with respect to the first side surface 1031 to divide the first side surface 1031 into a first dividing surface 1034 and a second dividing surface 1035. Wherein the first divider surface 1034 is proximate to the first surface 101 and the second divider surface 1035 is proximate to the second surface 102.

Referring also to fig. 4, the cross section of the sliding groove 104 is stepped. Specifically, the chute 104 includes a bottom surface 1041, a first side surface 1042, and a second side surface 1043. The first side surface 1042 and the second side surface 1043 are oppositely disposed on the bottom surface 1041 to form the chute 104. The first side surface 1042 and the second side surface 1043 are both stepped in cross section. The first side surface 1042 includes a first step surface 1044 and a second step surface 1045. The second step surface 1045 is formed by being recessed toward the first surface 101 relative to the first step surface 1044, so as to obtain a first side surface 1042 with a step-shaped cross section. The second step surface 1045 is far away from the bottom surface 1041 relative to the first step surface 1044. The second side surface 1043 includes a third step surface 1046 and a fourth step surface 1047. The fourth step surface 1047 is formed by being recessed toward the second surface 102 relative to the third step surface 1046, so as to obtain a second side surface 1043 with a step-shaped cross section. The fourth step surface 1047 is far away from the bottom surface 1041 relative to the third step surface 1046.

Referring to fig. 1 again, the sliding cover 30 is slidably connected to the front housing 10. In this embodiment, the sliding cover 30 is provided with a sliding block 301 matching with the sliding groove 104. The sliding block 301 is accommodated in the sliding groove 104 and can slide relative to the sliding groove 104, so that the sliding cover 30 is slidably connected to the front housing 10.

Referring also to fig. 5, in particular, the slide cover 30 includes a bottom wall 302 and a peripheral wall 304. In this embodiment, the peripheral wall 304 is substantially U-shaped. The peripheral wall 304 includes two first side walls 3041 and a second side wall 3043. The two first sidewalls 3041 are disposed opposite to each other at the periphery of the bottom wall 302. The second sidewall 3043 is disposed around the bottom wall 302 and connected between the two first sidewalls 3041 to form a sliding cover 30 with an opening 303. Thus, the slide cover 30 can correspondingly accommodate the slide block 301 in the slide slot 104 through the opening 303.

Referring to fig. 4 again, the slider 301 is protruded from an end of the first sidewall 3041 away from the bottom wall 302, and is located on the same side of the first sidewall 3041 as the bottom wall 302. The slider 301 includes a top surface 3011, a first connection surface 3012, and a second connection surface 3013 opposite to the first connection surface 3012. The top surface 3011 is connected between the first connection surface 3012 and the second connection surface 3013 and is opposite to the first sidewall 3041.

The first connection face 3012 and the first side face 1042 mate. Specifically, the cross section of the first connection surface 3012 is also stepped. The first connection surface 3012 includes a first mating surface 3014 and a second mating surface 3015. The first mating face 3014 is formed by being recessed away from the bottom wall 302 relative to the second mating face 3015, so as to obtain a first connection face 3012 with a step-shaped cross section. The first mating face 3014 is close to the top face 3011 relative to the second mating face 3015.

The second connection surface 3013 is matched with the second side surface 1043. The cross section of the second connection surface 3013 is also stepped. The second connection face 3013 includes a third mating face 3016 and a fourth mating face 3017. The third mating surface 3016 is formed by being recessed toward the bottom wall 302 with respect to the fourth mating surface 3017, thereby obtaining a second connection surface 3013 having a step-shaped cross section. The third mating face 3016 is close to the top face 3011 opposite to the fourth mating face 3017. Thus, when the sliding block 301 is accommodated in the sliding slot 104, the first connection surface 3012 and the second connection surface 3013 are respectively disposed corresponding to the first side surface 1042 and the second side surface 1043, so as to ensure the stability of the sliding cover 30 sliding relative to the front housing 10.

Further, the distance between the sliding groove 104 and the sliding block 301 is limited to avoid the sliding of the sliding cover 30 relative to the front housing 10 from shaking perpendicular to the sliding direction, such as shaking in the first direction (i.e., the X-axis direction) and the second direction (i.e., the Y-axis direction). The recess direction of the sliding groove 104 is a first direction, and the protruding direction of the sliding block 301 is also the first direction. Specifically, the distance D1 between the bottom surface 1041 and the top surface 3011 is set to 0.07mm, the distance D2 between the first step surface 1044 and the first mating surface 3014 is set to 0.15mm, the distance D3 between the second step surface 1045 and the second mating surface 3015 is set to 0.3mm, the distance D4 between the first separating surface 1034 and the first side wall 3041 is set to 0.12mm, and the distance D between the fourth step surface 1047 and the fourth mating surface 3017 is set to 0mm, that is, the fourth step surface 1047 is in complete contact with the fourth mating surface 3017.

It can be understood that, since the fourth step surface 1047 is in full contact with the fourth mating surface 3017, a lubricant may be coated on both the fourth step surface 1047 and the fourth mating surface 3017 to ensure that the sliding block 301 slides smoothly and silently relative to the sliding slot 104. Wherein the lubricant may be teflon.

Referring to fig. 2 again, in order to further prevent the sliding cover 30 from shaking perpendicular to the sliding direction during the sliding process relative to the front housing 10, at least one rib 105 may be disposed on the front housing 10. Specifically, the protruding rib 105 is protruded from the first surface 101, and is formed by extending the bottom surface 1032 toward the top surface 1033. The number of the convex ribs 105 can be adaptively adjusted according to actual needs, and can be one, two, three, and the like.

In this embodiment, the front case 10 includes two ribs 105. The two ribs 105 are arranged substantially in parallel. The rib 105 includes a first end 1051 and a second end 1052. The first end 1051 is distal to the bottom surface 1032 opposite the second end 1052. Accordingly, the sliding cover 30 is provided with a groove 305 matching with the rib 105. The groove 305 is disposed on the surface of the bottom wall 302 facing the peripheral wall 304. The groove 305 is used for accommodating the convex rib 105. The sliding direction of the rib 105 relative to the groove 305 is the same as the sliding direction of the sliding cover 30 relative to the front shell 10. Wherein the height of the second end 1052 relative to the first surface 101 is slightly higher than the height of the first end 1051 relative to the first surface 101. Thus, when the sliding block 301 is correspondingly slidably connected to the sliding groove 104, the protruding rib 105 is correspondingly received in the groove 305, so as to prevent the sliding cover 30 from swinging vertically to the sliding direction when sliding relative to the front shell 10, and ensure the stability of sliding of the sliding cover 30 relative to the front shell 10.

Preferably, the height of the first end 1051 relative to the first surface 101 is 0.15mm, and the height of the second end 1052 relative to the first surface 101 is 0.25 mm.

It will be appreciated that in this embodiment, since the contact between the protruding rib 105 and the groove 305 is completed during the sliding process, in order to ensure the smooth and silent sliding of the protruding rib 105 relative to the groove 305, a lubricant may be applied to both the protruding rib 105 and the groove 305. Wherein the lubricant may be teflon.

Referring to fig. 3 again, in the present embodiment, the front shell 10 further includes two elastic pieces 50. The two resilient pieces 50 are disposed on the front case 10. Specifically, the second surface 102 of the front case 10 is provided with two fixing portions 106. The two fixing portions 106 are used for mounting the two elastic pieces 50 on the front housing 10. Each fixing portion 106 includes a fixing post 1061, a limiting post 1062, and a through hole 1063. The fixing post 1061 and the limiting post 1062 are both protruded from the second surface 102, and the limiting post 1062 is adjacent to and corresponds to a connection portion of the first side surface 1031 and the bottom surface 1032. The through hole 1063 is disposed on the bottom surface 1041 and penetrates through the bottom surface 1041. The fixing posts 1061 are adjacent to and corresponding to the bottom surface 1032 and are on the same horizontal line with the limiting posts 1062. The limiting column 1062 is close to the through hole 1063 relative to the fixing column 1061.

Referring to fig. 6, each elastic piece 50 includes an elastic portion 501 and a connecting portion 503. The resilient portion 501 includes a connecting arm 5011, a first resilient arm 5012, and a second resilient arm 5013. The connecting arm 5011 is connected between the first and second

resilient arms

5012 and 5013. The first resilient arm 5012 is bent toward the connecting arm 5011 to form a locking angle 5014. The clip angle 5014 is a bending area of a portion of the first elastic arm 5012 relative to a portion of the connecting arm 5011. The second resilient arm 5013 is bent toward the first resilient arm 5012 with respect to the connecting arm 5011. The connecting portion 503 is disposed at one end of the second elastic arm 5013 away from the connecting arm 5011. The connection portion 503 further includes a connection hole 5031. The connection hole 5031 penetrates the connection part 503. Thus, the fixing posts 1061 pass through the connecting holes 5031, and the locking corners 5014 are exposed out of the bottom 1041 through the through holes 1063, so that the elastic sheet 50 is disposed on the front housing 10. Wherein the connection point of the second resilient arm 5013 and the connecting arm 5011 is located between the connection points of the limiting post 1062 and the first side surface 1031 and the bottom surface 1032 to define the bending angle of the connecting arm 5011 relative to the second resilient arm 5013.

Correspondingly, a clamping groove 306 matched with the elastic sheet 50 is arranged on the sliding block 301 of the sliding cover 30 and is used for being matched with the elastic sheet 50 to ensure the hand feeling of the sliding cover 30 in place. Meanwhile, the sliding device can be used for limiting the sliding range of the sliding cover 30 relative to the front shell 10, so as to prevent the sliding cover 30 from being separated from the front shell 10 in the sliding process, and play a role of stopping. The clip angle 5014 of the elastic piece 50 is movably contained in the clip groove 306.

In this embodiment, the sliding cover 30 includes four card slots 306. Each slider 301 is provided with two card slots 306. One of the slots 306 is disposed at an end of the slider 301 away from the second sidewall 3043, and the other slot 306 is disposed at an end of the slider 301 close to the second sidewall 3043. Wherein the sliding cover 30 slides in a range between the two card slots 306 with respect to the front housing 10. For convenience of description, the card slot 306 away from the second side wall 3043 is defined as a first card slot 3061, and the card slot 306 near the second side wall 3043 is defined as a second card slot 3062.

Specifically, the slot 306 is formed by the top surface 3011 of the slider 301 being recessed toward the first sidewall 3041. The slot 306 includes two inclined surfaces 3063 and is generally V-shaped in cross-section. Preferably, the two inclined surfaces 3063 form an included angle of 120 °. Thus, in the sliding process of the sliding cover 30 relative to the front housing 10, the top surface 3011 of the slider 301 always abuts against the corner 5014 of the elastic piece 50, so that the connecting arm 5011 is bent toward the second elastic arm 5013 to form an elastic force. When the sliding cover is pushed to the slot 306, the locking corner 5014 is separated from the top surface 3011, and returns to the initial state under the elastic force formed by the connecting arm 5011 and the second elastic arm 5013, and is contained in the slot 306, so as to determine whether the sliding cover 30 is in place relative to the front housing 10.

Further, in order to ensure a better elastic force between the connecting arm 5011 and the second elastic arm 5013, an included angle between the connecting arm 5011 and the second elastic arm 5013 is set to 130 ° to 135 °.

Hereinafter, a process of attaching the slide cover 30 to the front case 10 and a sliding principle thereof will be described in detail.

First, the slider 301 is disposed in the sliding groove 104 through the opening 303 at an end of the sliding cover 30 away from the second sidewall 3043, and the protruding rib 105 is received in the groove 305. The clip angle 5014 of the elastic piece 50 is correspondingly accommodated in the first clip groove 3061, so as to complete the installation of the sliding cover 30. At this time, the slide cover 30 is opened with respect to the front case 10 (see fig. 1).

Then, the sliding cover 30 is gradually pushed to move towards the top surface 1033, and the card corner 5014 will be separated from the first card slot 3061 and abut against the top surface 3011 of the slider 301, so that the connecting arm 5011 moves towards the second elastic arm 5013 to form an elastic force.

Referring to fig. 7, when the sliding cover 30 is continuously pushed to the second slot 3062, the locking corner 5014 is separated from the top surface 3011, and returns to the initial state under the elastic force formed by the connecting arm 5011 and the second elastic arm 5013 and is received in the second slot 3062. At this time, the slide cover 30 is in a closed state with respect to the front case 10.

Further, if the slide cover 30 is opened relative to the front housing 10, the slide cover 30 is pushed to move toward the bottom surface 1032, so that the corner 5014 is separated from the second slot 3062 and abuts against the top surface 3011, thereby driving the connecting arm 5011 to move toward the second elastic arm 5013 to form an elastic force. When the card is pushed to the first card slot 3061, the card corner 5014 is separated from the top surface 3011, and returns to the initial state under the elastic force formed by the connecting arm 5011 and the second elastic arm 5013, and is accommodated in the first card slot 3061. At this time, the slide cover 30 is opened with respect to the front case 10.

In summary, the slide block 301 of the slide cover 30 is correspondingly accommodated in the slide slot 104 of the front housing 10, so that the slide cover 30 slides relative to the front housing 10. The cross sections of the sliding block 301 and the sliding groove 104 are in a step shape. Meanwhile, the distance between the slider 301 and the sliding slot 104 is limited to prevent the sliding cover 30 from shaking in the first direction and the second direction during the sliding process relative to the front housing 10. In addition, the sliding cover 30 and the front shell 10 are respectively provided with a rib 105 and a groove 305 matched with the rib 105, so that the sliding cover 30 is further prevented from shaking in the first direction relative to the front shell 10 in the sliding process, and the sliding hand feeling and the user experience are improved.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
