Detailed Description

For the purposes of making the objects and embodiments of the present utility model more apparent, an exemplary embodiment of the present utility model will be described in detail below with reference to the accompanying drawings in which exemplary embodiments of the present utility model are illustrated, it being apparent that the exemplary embodiments described are only some, but not all, of the embodiments of the present utility model.

It should be noted that the brief description of the terminology in the present utility model is for the purpose of facilitating understanding of the embodiments described below only and is not intended to limit the embodiments of the present utility model. Unless otherwise indicated, these terms should be construed in their ordinary and customary meaning.

The terms first, second, third and the like in the description and in the claims and in the above-described figures are used for distinguishing between similar or similar objects or entities and not necessarily for describing a particular sequential or chronological order, unless otherwise indicated. It is to be understood that the terms so used are interchangeable under appropriate circumstances.

The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a product or apparatus that comprises a list of elements is not necessarily limited to all elements explicitly listed, but may include other elements not expressly listed or inherent to such product or apparatus.

At present, a rear shell of a television is usually required to be installed in a threaded hole on a back plate by using a screw, in order to reduce the cost of the television, the back plate is required to be thinned, specifically, the wall thickness of the thinned back plate is generally about 0.5mm, and due to the fact that the wall thickness of the back plate is thinner, a sliding phenomenon (also called a sliding phenomenon) is easy to occur after a fastener is penetrated in the threaded hole of the back plate, so that connection between the rear shell and the back plate fails, and the back plate is scrapped.

For this reason, in the prior art, a fastening structure is generally adopted to realize connection between the back plate and the rear shell, but the fastening connection mode is not stable enough, and in some situations, connection failure between the back plate and the rear shell can also occur. Therefore, how to achieve reliable connection of the back plate and the back shell to avoid the back plate from being scrapped, and without increasing the thickness of the back plate itself to achieve the control cost are problems to be solved by the present embodiment.

In view of this, referring to fig. 1 to 16, the present embodiment provides a connection structure between a back shell and a back plate, including a back plate 1 and a back shell 2. The back plate 1 may be a back plate of a display device, and the rear case 2 may be a rear case of the display device, for example.

Wherein, the back shell 2 is positioned at one side of the back plate 1, and the back shell 2 is provided with a first threaded hole 21.

The position that corresponds with first screw hole 21 on backplate 1 is provided with dodges the hole 11 that can supply fastener 4 to pass, and one side of backplate 1 deviating from backshell 2 is connected with the bodiness structure 3, and the position that corresponds with first screw hole 21 on the bodiness structure 3 is provided with second screw hole 31, and backshell 2 is connected with backplate 1 through wearing to establish in first screw hole 21, dodge hole 11 and second screw hole 31 and respectively with first screw hole 21 and second screw hole 31 screw-thread fit's fastener 4.

In particular, the rear housing 2 may be arranged on a side of the back plate 1 facing away from the display surface of the display device. For example, referring to the vertical direction of the drawing shown in fig. 1, for example, the backshell 2 is set above the backplate 1, at this time, the thickening structure 3 may be set at the bottom of the backplate 1, thereby the local wall thickness increase of the backplate 1 may be achieved through the thickening structure 3 set at the bottom of the backplate 1, the first threaded hole 21 for penetrating the fastener 4 is provided on the backshell 2, the avoidance hole 11 is provided at the position corresponding to the first threaded hole 21 on the backplate 1, and the second threaded hole 31 is provided at the position corresponding to the first threaded hole 21 on the thickening structure 3, so that the fastener 4 penetrates through the first threaded hole 21, the avoidance hole 11 and the second threaded hole 31 and is respectively in threaded fit with the first threaded hole 21 and the second threaded hole 31, so that the backplate 1 and the backshell 2 may be firmly connected together, and the problem of sliding teeth caused by the thinner thickness of the backplate 1 may be avoided, thereby the normal use of the backplate 1 may be ensured, the waste is avoided, and the wall thickness of the backplate 1 itself does not need to be increased, thereby the backplate 1 itself may be reduced, so that the cost may be controlled, and the display device with small size (such as a television) having the connection of the backplate and the thin-size may be combined with the television.

In particular, the inner diameter of the avoidance hole can be larger than the inner diameters of the second threaded hole 31 and the first threaded hole 21, namely, the aperture of the avoidance hole 11 (namely, the inner diameter of the avoidance hole 11) is larger than the outer diameter of the fastener 4, so that the fastener 4 connected with the first threaded hole 21 can quickly penetrate through the avoidance hole and then be matched with the second threaded hole 31, namely, the avoidance hole 11 on the back plate 1 only plays a role in allowing the fastener 4 to penetrate without being connected with the fastener 4, and therefore, the fastening connection between the back plate 1 and the back plate 2 is realized mainly through the second threaded hole 31 on the thickening structure 3 and the first threaded hole 21 on the back plate 2, and the problems that the back plate 1 is scrapped and the back plate 2 is in linkage failure with the back plate 1 due to easy sliding teeth caused by thinner wall thickness of the back plate 1 when the fastener 4 is connected with the avoidance hole 11 on the back plate 1 are avoided. At this time, the first screw hole 21 and the second screw hole 31 may be screw holes, the fastener 4 may be a screw or bolt or a screw rod that is adapted to the screw holes, and the avoiding hole 11 may be a light hole.

It should be noted that, since the fastener 4 is mainly connected with the first threaded hole 21 of the rear shell 2 and the second threaded hole 31 of the thickening structure 3 in a matching manner to realize connection between the rear shell 2 and the rear shell 1, the thickness of the thickening structure 3 can be set to be a little larger, for example, can be larger than the thickness of the rear shell 1, so that sliding teeth cannot occur when the fastener 4 is connected with the second threaded hole 31.

Illustratively, the thickness of the thickening structure 3 may range from 0.8mm to 1.0mm, such that it is greater than the thickness of the backplate 1 (the thickness of the backplate 1 is typically 0.5 mm), so that no tooth or thread slipping occurs when the second threaded holes 31 are provided in the thickening structure 3 for connection with the fasteners 4.

The thickness of the thickening structure 3 may be, for example, 0.8mm, or may be 0.9mm, or may be 1.0mm, and the thickness of the thickening structure 3 may be set according to actual needs, which is not particularly limited in this embodiment.

According to the connection structure of the rear shell and the back plate, through the thickening structure 3 additionally arranged on one side, deviating from the rear shell 2, of the back plate 1, the effect of indirectly increasing the local wall thickness of the back plate 1 to a certain extent can be achieved through the thickening structure 3 additionally arranged on one side of the back plate 1, the second threaded hole 31 is formed in the position, corresponding to the first threaded hole 21, of the thickening structure 3, the avoidance hole 11 is also formed in the position, corresponding to the first threaded hole 21, of the back plate 1, accordingly, the problem that connection failure is caused by easy sliding teeth or sliding wires due to the fact that the wall thickness of the back plate 1 is thinner when the back plate 1 is connected with the back plate 1 can be avoided by threading the fastener 4 into the first threaded hole 21, the avoidance hole 11 and the second threaded hole 31 and respectively in threaded fit with the first threaded hole 21 and the second threaded hole 31.

Referring to fig. 1, 14-16, in some embodiments, the thickening structure 3 includes a thickening plate 32 and a thickening protrusion 33 disposed on a side of the thickening plate 32 facing away from the rear shell 2, the second threaded hole 31 is disposed through the thickening plate 32 and the thickening protrusion 33, and a projection of the thickening protrusion 33 on the thickening plate 32 is located in an area where the thickening plate 32 is located.

In particular, referring to fig. 1 and 14, the thickening structure 3 may include a planar thickening plate 32 extending in a radial direction parallel to the first threaded hole 21 and a thickening protrusion 33 provided at a bottom of the thickening plate 32, and the second threaded hole 31 connected to the fastener 4 penetrates the thickening plate 32 and the thickening protrusion 33, so that an axial extension length (a dimension in a direction from the rear case 2 to the rear case 1) of the second threaded hole 31 is a sum of a thickness of the thickening plate 32 (a dimension in a direction from the rear case 2 to the rear case 1) and a thickness of the thickening protrusion 33 (a dimension in a direction from the rear case 2 to the rear case 1), and further, the second threaded hole 31 may have a sufficient axial extension length to be engaged with the fastener 4, thereby preventing a sliding tooth or a sliding wire phenomenon from occurring when the fastener 4 is connected to the second threaded hole 31, thereby ensuring an effective connection between the rear case 1 and the rear case 2, and avoiding a connection failure.

For example, the thickness of the thickening protrusion 33 may be greater than the thickness of the thickening plate 32, and the projection of the thickening protrusion 33 onto the thickening plate 32 may be located entirely within the area where the thickening plate 32 is located, i.e., the outer contour size of the thickening protrusion 33 is smaller than the outer contour size of the thickening plate 32, so that the thickening structure 3 may achieve a significant increase in the axial size of the second threaded hole 31 through the thickening protrusion 33 and may avoid the problems of occupying space and causing an increase in weight and cost due to the larger arrangement of the thickening protrusion 33.

For example, the thickening plate 32 and the thickening bump 33 may be integrally formed, so as to save manufacturing process and improve the overall structural strength of the thickening structure 3. Illustratively, the thickening plate 32 and the thickening projections 33 may be integrally injection molded from plastic, thereby making them lightweight and allowing for control of material costs. Or the thickening plate 32 and the thickening convex block 33 can be integrally cast by adopting alloy, so that the structural strength and the rigidity are higher, and the service life is prolonged.

Or in other implementations, the thickening plate 32 and the thickening bump 33 may be bonded together or welded or snapped together after being molded separately.

Illustratively, the thickening projections 33 may be rectangular thickening projections having a rectangular cross section, or the thickening projections 33 may be cylindrical thickening projections having a circular cross section.

Referring to fig. 2 to 13, the connection structure of the thickening structure 3 at the bottom of the back plate 1 may be: one side of the back plate 1, which is away from the back shell 2, is provided with a clamping structure 5, and the thickening structure 3 can slide to be connected with the clamping structure 5 relative to the back plate 1 along a direction towards the part close to the clamping structure 5, or slide to be disconnected with the clamping structure 5 along a direction away from the part of the clamping structure 5, so that quick and convenient assembly or disassembly separation between the back plate 1 and the thickening structure 3 is realized.

Specifically, referring to fig. 2 and fig. 10 to fig. 13, the back plate 1 is provided with a clamping structure 5, and the clamping structure 5 can be connected with the thickening structure 3, so that the thickening structure 3 is reliably connected to the bottom of the back plate 1, and can be disconnected from the thickening structure 3, so that when any one of the thickening structure 3 and the back plate 1 needs to be replaced, only one of the thickening structure 3 and the back plate 1 is required to be replaced, and the problem of waste caused by overall replacement is avoided.

In particular, when the current state of the thickening structure 3 is that the clamping structure 5 and the thickening structure 3 are in an unconnected state, and a set portion of the clamping structure 5 is located at the front side of the thickening structure 3, as shown in fig. 10 and 11, when the thickening structure 3 needs to be reliably connected to the backboard 1, the thickening structure 3 can be made to slide forward (in the direction of the arrow shown in fig. 11) so that the thickening structure 3 and the clamping structure 5 are connected and are in a connected state, and at the moment, the backboard 1 and the thickening structure 3 are connected together, specifically referring to the position state shown in fig. 12 and 13.

Similarly, as shown in fig. 12 and 13, when the current state of the thickening structure 3 is that the clamping structure 5 is connected to the thickening structure 3, a set portion of the clamping structure 5 is located at the front side of the thickening structure 3, and when the thickening structure 3 needs to be separated from the back plate 1, the thickening structure 3 may be slid backward (opposite to the arrow shown in fig. 13), so that the thickening structure 3 is disconnected from the clamping structure 5 and is in an unconnected state, specifically referring to the position states shown in fig. 6 and 7.

As shown in fig. 11, when the thickened structure 3 is not slid to be engaged with the engagement structure 5, the second screw hole 31 is not aligned with the first screw hole 21, the fastener 4 cannot connect the first screw hole 21 and the second screw hole 31, and the rear case 2 and the rear plate 1 are not connected by the fastener 4. Referring to fig. 7, when the thickening structure 3 slides to be clamped with the clamping structure 5, the second threaded hole 31 and the first threaded hole 21 are coaxially arranged to achieve alignment, and the fastener 4 can be inserted into the first threaded hole 21, the avoidance hole 11 and the second threaded hole 31 to achieve reliable connection between the back plate 1 and the rear shell 2.

In addition, referring to fig. 2, 11 and 13, the side of the back plate 1 facing away from the back shell 2 has a cavity 14, and the clamping structure 5 may be located in the cavity 14, so as to fully utilize the space of the cavity 14 to arrange the clamping structure 5 and the thickening structure 3, and avoid increasing the thickness of the back plate 1 to a certain extent.

Illustratively, the cavity 14 may have a cavity profile that is larger than the outer profile of the thickening structure 3, thereby facilitating placement of the thickening structure 3 within the cavity 14. Or in other implementations, it is also possible to provide that the inner contour shape of the cavity 14 is adapted to the outer contour shape of the thickening structure 3.

In particular, the cavity 14 may be formed by hollowing out a side of the back plate 1 facing away from the back shell 2.

For example, the side of the thickening structure 3 facing away from the rear shell 2 may be flush with the cavity opening of the cavity 14, or the side of the thickening structure 3 facing away from the rear shell 2 may be lower than the cavity opening of the cavity 14, so that the thickening structure 3 may be fully accommodated in the cavity 14 to avoid the problem of increasing the thickness of the back plate 1 caused by the protrusion of the thickening structure 3 from the cavity 14.

Referring to fig. 2-13, in some embodiments, the clamping structure 5 includes a first clamping protrusion 51, and the thickening structure 3 is slidable relative to the back plate 1 in a direction toward the first clamping protrusion 51 to be in abutting engagement with the first clamping protrusion 51.

That is, when the thickening structure 3 is in a state of being not connected with the clamping structure 5, the first clamping protrusion 51 is located at the front side of the thickening structure 3, so that the thickening structure 3 can slide forward to be in abutting fit with the first clamping protrusion 51, and when the thickening structure 3 is in abutting fit with the first clamping protrusion 51, the first clamping protrusion 51 can limit the thickening structure 3 to slide forward continuously, so that a limiting effect of moving the thickening structure 3 in the front side direction is achieved.

Referring to fig. 2 to 13, a side of the first locking protrusion 51 facing away from the rear case 2 is provided with a first extension portion 52, and the first extension portion 52 extends toward a direction approaching the thickening structure 3, and the thickening structure 3 is configured to be locked on a side of the first extension portion 52 approaching the rear case 2 when abutting against the first locking protrusion 51.

That is, the side of the first clamping protrusion 51 facing away from the rear shell 2 is provided with the first extension portion 52 and extends toward the thickening structure 3, so that after the thickening structure 3 slides to abut against the first clamping protrusion 51 to limit the thickening structure 3 to slide forward, a part of the thickening structure 3 is clamped on the side of the first extension portion 52, which is close to the rear shell 2, so as to realize clamping of the thickening structure 3, so as to limit the thickening structure 3 from falling off from the rear shell 1 in a direction away from the rear shell 2, i.e. limit the thickening structure 3 in a thickness direction along the rear plate 1.

Referring to fig. 2 to 13, in some embodiments, a notch 12 is provided on the back plate 1 at a position corresponding to the thickening structure 3, a clamping structure 5 is provided on an inner edge of one side of the notch 12, a suspension plate 13 is provided on an inner edge of the other side of the notch 12, a avoiding hole 11 is provided on the suspension plate 13, an abutting protrusion 131 is provided on the other end of the suspension plate 13, and a through hole 34 adapted to the abutting protrusion 131 is provided on the thickening structure 3.

The propping protrusion 131 is used for being pressed on one side, close to the rear shell 2, of the thickening structure 3 when the thickening structure 3 and the clamping structure 5 are released from propping, and the propping protrusion 131 is used for penetrating out of the through hole 34 and propping and matching with the thickening structure 3 when the thickening structure 3 and the clamping structure 5 are propped.

In particular, referring to the front-rear direction and the left-right direction of the drawings shown in fig. 11 and 13, the inner edge of the notch 12 includes, for example, a front inner edge, a rear inner edge, a left inner edge and a right inner edge, the first engaging protrusion 51 is provided at the front inner edge, and the rear inner edge of the notch 12 is provided with the suspension 13.

Referring to fig. 11, when the thickening structure 3 is in a state of not being clamped with the first clamping protrusion 51, the abutting protrusion 131 is pressed on a side of the thickening structure 3 close to the rear shell 2, that is, between the abutting protrusion 131 and the thickening structure 3, between the thickening structure 3 and the first clamping protrusion 51, and between the thickening structure 3 and the first extension portion 52, there is no connection and cooperation.

Referring to fig. 13, when the thickening structure 3 slides forward to be in abutting engagement with the first engaging protrusion 51 and is engaged with the side of the first extending portion 52 near the rear shell 2, the elastic sheet rebounds toward the direction near the thickening structure 3 and makes the abutting protrusion 131 pass through the through hole 34 and abut against the front inner edge of the notch 12, and the thickening structure 3 jointly realizes the limit of the thickening structure 3 in the front-rear direction through the abutting protrusion 131 and the first engaging protrusion 51, and the first extending portion 52 realizes the limit of the thickening structure 3 in the thickness direction, and the thickening structure 3 cannot move in the front-rear direction and the height direction, so that the reliable connection of the thickening structure 3 on the rear plate 1 is ensured to a certain extent.

It should be noted that, for the suspension 13 disposed on the inner edge of the rear side of the notch 12, the rear end of the suspension 13 is connected with the inner edge of the rear side of the notch 12, and gaps exist between the left side, the front end and the right side of the suspension 13 and the inner edge of the notch 12, so that the suspension 13 presents a structure with one end connected and the other end in a suspension state, so that the suspension 13 can be pressed at the bottom of the thickening structure 3 and can rebound upwards and make the abutment protrusion 131 pass through the through hole 34 to realize the abutment fit of the thickening structure 3 when the thickening structure 3 slides to the through hole 34 to correspond to the abutment protrusion 131.

For example, the suspension 13 and the back plate 1 may be integrally formed, so as to save manufacturing process and improve the overall structural strength of the back plate 1. For example, both the suspension 13 and the back plate 1 may be made of an alloy. Or the suspension 13 and the backboard 1 can be clamped together or welded together after being molded separately.

The first engaging protrusion 51 may be, for example, an arc-shaped protrusion protruding in a direction away from the rear case 2, and the first extension 52 may be a first extension plate provided at one side of the arc-shaped protrusion and extending toward the thickening structure 3. Further, the abutment projection 131 may also be an arc-shaped projection projecting in a direction away from the rear case 2.

Referring to fig. 2 to 13, in some embodiments, the clamping structure 5 further includes two second clamping protrusions 53, where the two second clamping protrusions 53 are disposed on inner edges of opposite sides of the notch 12 and are disposed adjacent to the first clamping protrusions 51; the two second clamping protrusions 53 are used for being in abutting fit with the thickening structure 3 when the thickening structure 3 is clamped and fixed with the first clamping protrusions 51.

In particular, when referring to the left-right and front-back directions of the drawings shown in fig. 11 and 13, when the thickening structure 3 slides to be connected with the first clamping protrusion 51, the first clamping protrusion 51 is located at the front side of the thickening structure 3, at this time, the two second clamping protrusions 53 may be separately located at the left side and the right side of the thickening structure 3, so that when the thickening structure 3 slides forward to be in abutting fit with the first clamping protrusion 51 and is clamped at one side of the first extension part 52 near the rear shell 2, the spring plate rebounds towards the direction near the thickening structure 3, at this time, the abutting protrusion 131 penetrates out from the through hole 34 and abuts against the front inner edge of the notch 12, and both the left end and the right end of the thickening structure 3 abut against the corresponding second clamping protrusion 53, at this time, the first clamping protrusion 51 and the abutting protrusion 131 realize front-back limiting of the thickening structure 3 in the thickness direction, the first extension part 52 realizes limiting of the thickening structure 3 in the thickness direction, and the two second clamping protrusions 53 realize limiting of the thickening structure 3 in the left-right direction, thereby ensuring reliable connection of the backboard 3 in the opposite direction to the backboard 1.

For example, the two second clamping protrusions 53 may be arc protrusions protruding along a direction away from the rear shell 2, and the two second clamping protrusions 53 may be symmetrically disposed on the left and right sides of the thickening structure 3, so that the thickening structure 3 may be respectively in abutting fit with the two second clamping protrusions 53 after sliding in place.

Referring to fig. 2 to 13, in some embodiments, a second extension 54 is disposed on a side of at least one of the two second clamping protrusions 53 facing away from the rear case 2, and the second extension 54 extends toward the thickening structure 3, where the thickening structure 3 is configured to be clamped to a side of the second extension 54 near the rear case 2 when abutting against the second clamping protrusion 53.

In particular, only one side of the second clamping protrusion 53 on the left, which is away from the rear shell 2, may be provided with the second extension portion 54 extending toward the thickening structure 3, so that the thickening structure 3 is clamped to one side of the first extension portion 52, which is close to the rear shell 2, and simultaneously clamped to one side of the second extension portion 54 on the left, which is close to the rear shell 2, so that the limiting reliability of the thickening structure 3 in the thickness direction is further improved.

Or only one side of the second clamping protrusion 53 on the right, which is away from the rear shell 2, is provided with the second extension portion 54 extending towards the thickening structure 3, so that the thickening structure 3 is clamped on one side of the first extension portion 52, which is close to the rear shell 2, and simultaneously clamped on one side of the second extension portion 54 on the right, which is close to the rear shell 2, and then the limiting reliability of the thickening structure 3 in the thickness direction is further improved.

Or the side, away from the rear shell 2, of the second clamping protrusion 53 on the left side can be simultaneously provided with the second extension portion 54 extending towards the thickening structure 3, and the side, away from the rear shell 2, of the second clamping protrusion 53 on the right side is provided with the second extension portion 54 extending towards the thickening structure 3, so that the thickening structure 3 is simultaneously clamped on one side, close to the rear shell 2, of the second extension portion 54 on the left side and one side, close to the rear shell 2, of the second extension portion 54 on the right side when the first extension portion 52 is clamped on one side, close to the rear shell 2, of the thickening structure 3, and then limiting reliability of the thickening structure 3 in the thickness direction is further remarkably improved.

The first extension 52 may be, for example, a first extension plate or a first extension piece provided at one side of the arc-shaped protrusion and extending in a direction toward the thickening structure 3.
