[0046] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0047] Example 1

[0048] like Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention is a camera gusset plate for a display screen door, comprising a fixing plate 10, a camera is mounted on the fixing plate 10, and a pressing block bearing area 15 is provided on the fixing plate 10; wherein,

[0049] The pressing block bearing area 15 is a hollow structure, and the pressing block bearing area 15 and the pressing block 41 are integrally injection-molded;

[0050] The plurality of protrusions 411 on both sides of the pressing block 41 are circumscribed within the contour of the pressing block bearing area 15 , and the pressing block 41 can be snapped off from the pressing block bearing area 15 .

[0051] In one embodiment, the periphery of the pressing block bearing area 15 is fixed to the fixing plate 10 via a plastic fixing frame. In another embodiment, the fixing plate 10 is a plastic part, and the fixing plate 10 and the pressing block 41 are integrally formed by injection molding.

[0052] The pressure block bearing area 15 is equipped with connecting arms 151 connected to the several protrusions 411 on both sides of the pressure block 41. When the pressure block 41 is released, the connection between the connecting arms 151 and the pressure block 41 is broken. The connecting arms 151 gradually narrow toward the protrusions 141, making the connection between the connecting arms 151 and the pressure block 41 easier to break under external force. Furthermore, the outer end surface dimensions of the connecting arms 151 are consistent with the outer end surface dimensions of the protrusions 411.

[0053] In this embodiment, the number of the pressing block bearing area 15 is one.

[0054] In another embodiment, the number of the pressing block bearing areas 15 is at least two. For example, the number of the pressing block bearing areas 15 is two, and two pressing blocks 41 are formed by injection molding and kept as backup to prevent the pressing blocks 41 from being damaged and requiring replacement.

[0055] Example 2

[0056] like Figure 4 、 Figure 5 As shown, the present invention provides a camera clamping structure for a display door, comprising the fixing plate 10 as described above, a clamping assembly 40 provided on the fixing plate 10, a camera mounted in a camera mounting hole 14 on the fixing plate 10, the clamping assembly 40 comprising a clamping block 41 and a clamping member 42 for buckling the clamping block 41 against the back of the camera; wherein,

[0057] The clamping member 42 is provided on the fixing plate 10, and the pressure block 41 is pulled out from the pressure block bearing area 15 and buckled into the clamping member 42; the clamping member 42 abuts against at least one end surface of the pressure block 41 to buckle the pressure block 41 so that the pressure block 41 is pressed against the back of the camera; the pressure block 41 can be buckled into or out of the clamping member 42 to realize the loading and unloading of the pressure block 41.

[0058] In one embodiment, the clamping member 42 is mounted on the back side of the fixing plate 10 , and the camera is used to photograph objects facing the front side of the fixing plate 10 .

[0059] The clamping member 42 includes at least one pair of opposing snap-in portions 421. These snap-in portions 421 protrude from the back of the fixed plate 10 and abut against the pressure block 41. These snap-in portions 421 are elastic members. In this embodiment, the clamping members 42 are a pair, each positioned opposite the other, with a corresponding pair of snap-in portions 421, which snap onto the pressure block 41 from either side. Because the snap-in portions 421 protrude from the back of the fixed plate 10, they can deform relative to the fixed plate 10 under external force, allowing the pressure block 41 to engage or disengage. These snap-in portions 421 can recover their original shape when no external force is applied.

[0060] Furthermore, the latching portion 421 is hook-shaped to latch onto two adjacent end surfaces of the pressing block 41. The pair of latching portions 421 lock the pressing block 41 from the three outer walls of the pressing block 41, so that the end surface of the pressing block 41 facing the camera is pressed against the back of the camera, thereby achieving a tight compression of the back of the camera.

[0061] Furthermore, the fixing plate 10 and the clamping assembly 40 are both plastic parts and have a certain degree of elasticity. When the pressure block 41 is inserted into the locking portion 421 from the outside, an external force is applied to press the pressure block 41 from the middle of the two oppositely arranged locking portions 421, and the two locking portions 421 are deformed toward the back of the fixing plate 10, and the two locking portions 421 are relatively opened to allow the pressure block 41 to be inserted. When the pressure block 41 is disengaged from the locking portion 421, an external force is applied to pull the pressure block 41 away from the two locking portions 421, and the two locking portions 421 are deformed in a direction away from the back of the fixing plate 10, and the two locking portions 421 are relatively opened to allow the pressure block 41 to be disengaged, thereby achieving the connection or disconnection of the pressure block 41 and facilitating assembly and disassembly.

[0062] The clamping member 42 also includes a clamping arm 422 connected to the clamping portion 421. The clamping arm 422 is located on the fixed plate 10. The area between the two side walls of the clamping arm 422 and the fixed plate 10 is hollowed out. When an external force acts on the clamping portion 421, the clamping arm 422 can correspondingly deform to increase the elasticity of the clamping portion 421, thereby facilitating the fastening or release of the pressure block 41. Furthermore, the hollow area between the two oppositely arranged clamping portions 421 appropriately reduces the contact area between the pressure block 41 and the back of the fixed plate 10, thereby reducing the resistance force of the back of the fixed plate 10 on the pressure block 41, and facilitating the pressure block 41 to be pressed tightly against the back of the camera.

[0063] One end surface of the pressure block 41 is flat, designed to rest against the back of the camera. Specifically, the flat surface of the pressure block 41 presses against the back of the camera. One end surface of the pressure block 41 is provided with a recessed portion 4121 for pressing, facilitating application of force. Furthermore, one end surface of the pressure plate 41 is provided with a raised portion 412, with the recessed portion 4121 positioned on the raised portion 412. The raised portion 412 increases the depth of the recessed portion 4121, making it easier to press. When external force is applied, the recessed portion 4121 is pressed against the point of application. Because the sidewalls surrounding the recessed portion 4121 limit the point of application, this point of application is less likely to shift as force is applied.

[0064] The pressing block 41 is used to press the outer contour of the plane area on the back of the camera to cover the outer contour of the back of the camera. The flat end of the pressing block 41 presses tightly against the back of the camera and covers the outer contour of the back of the camera to increase the contact area between the pressing block 41 and the back of the camera, thereby increasing the pressing force of the pressing block 41 on the camera.

[0065] The pressure block 41 is provided with two engaging portions 413, one on either side of the raised portion 412. The engaging portions 413 are shorter than the raised portion 412 and engage with the inside of the latching portion 421. In one embodiment, the width of the hook structure of the latching portion 421, which abuts against the back of the engaging portion 413, is shorter than the width of the back surface of the engaging portion 413. This prevents the hook structures on the two opposing latching portions 421 from contacting the outer walls of the two raised portions 412, causing the two latching portions 421 to bounce away from each other and reduce the locking force of the pressure block 41.

[0066] The pressure block 41 is provided with two first limiting portions 414, respectively located on the two buckling portions 413. The two first limiting portions 414 are respectively disposed adjacent to or in close proximity to the side wall of the two latching portions 421, away from the camera, to limit the upward movement of the pressure block 41 relative to the clamping member 42. Furthermore, the two first limiting portions 414 are respectively connected to the side walls of the two raised portions 412. The clamping member 42 also includes a second limiting portion 423 disposed on the back side of the fixed plate 10. The second limiting portion 423 is a protrusion located outside the side wall of the pressure block 41 away from the camera and abuts against the pressure block 41 to limit the downward movement of the pressure block 41 relative to the clamping member 42. The two latching portions 421 limit the left-right and forward-backward movement of the pressure block 41, while the first limiting portion 414 and the second limiting portion 423 limit the upward and downward movement of the pressure block 41. This secures the pressure block 41 to the back side of the camera.

[0067] It should be understood that the snapping force of the snap portion 421 on the pressing block 41 is sufficient to meet the buckling requirements of the pressing block 41. In order to further improve the firmness of the pressing block 41 after assembly, a first limiting portion 414 or a second limiting portion 423 can be provided.

[0068] like Figure 6 、 Figure 7 As shown, a plurality of protrusions 411 are protruded from both side walls of the pressing block 41 , and the outer ends of the protrusions 411 are gradually narrowed toward the direction away from the protrusions 411 .

[0069] like Figure 1 、 Figure 3 As shown, the pressure block bearing area 15 is provided with a connecting arm 151 connected to a number of protrusions 411 on the two side walls of the pressure block 41. The width and thickness of the connecting arm 151 are relatively small; the size of the outer end face of the protrusion 411 is relatively small so as to be disconnected from the connection between the outer end face of the protrusion 411 and the connecting arm 151. In one embodiment, the connecting arm 151 is a gradually narrowing structure toward the protrusion 141. Furthermore, the connecting arm 151 gradually narrows until the size of the outer end face of the connecting arm 151 is consistent with the size of the outer end face of the protrusion 411. So that when the force is released from the pressure block bearing area 15 to detent the pressure block 41, the outer end face of the protrusion 411 on the pressure block 41 is smoothly disconnected from the connection between the connecting arm 151 and the outer end face, so as to facilitate the removal of the pressure block 41.

[0070] It should be understood that the front face or side wall of the camera is fixed by the mounting hole 14 , and the mounting hole 14 can adopt any existing structure that can fix the front face or side wall of the camera, which will not be described in detail here.

[0071] It should be understood that when the camera faces the back of the fixed plate 10, the clamping assembly 40 is arranged on the front of the fixed plate 10, and the other technical features are the same as the technical features when the camera faces the front of the fixed plate 10, and will not be repeated here.

[0072] Example 3

[0073] The present invention provides a display screen door body, including the camera clamping structure for the display screen door body as described above and a camera, a display screen assembly, and a main control board (not shown in the figure) installed on a fixed plate 10; the display screen assembly and the camera are electrically connected to the main control board respectively.

[0074] The display screen assembly includes a display screen, a touch TP panel, and a glass panel which are arranged in sequence. The glass panel is attached to the front of the fixing plate 10 . The display screen, the touch TP panel and the main control board are electrically connected.

[0075] The touch panel 23 can be a capacitive screen or a resistive screen. The touch panel 23 includes touch glass and a sensing layer disposed on the top of the touch glass. A flexible printed circuit board 231 (FPC) connected to the sensing layer is disposed at one end of the touch panel 23. The FPC 231 is electrically connected to the circuit control board, allowing the display assembly to receive user touch input signals and make corresponding interactive responses.

[0076] It should be understood that the figure only shows the flexible circuit board 231 exposed from the fixed plate 10, and does not show the specific structure for electrically connecting the flexible circuit board 231 to the circuit control board. The flexible circuit board 231 can be bent and hidden within the fixed plate 10 to be electrically connected to the circuit control board.

[0077] It should be understood that when the camera faces the back of the fixed plate 10 and the clamping assembly 40 is arranged on the front of the fixed plate 10, the display screen assembly can be first fixed by the display screen bracket, and then the display screen bracket can be detachably installed on the front of the fixed plate 10. Therefore, when the camera needs to be loaded and unloaded, the display screen bracket is first removed, and then the clamping block 41 is removed, and finally the camera is removed. The camera is also easy to load and unload.

[0079] The present invention provides a refrigerator, comprising a refrigerator body, wherein the refrigerator body comprises a foam door assembly, the foam door assembly comprises the display door body as described above, and the foam door assembly is pivotally connected to the refrigerator body.

[0080] In one embodiment, the foam door assembly is a hollow frame structure, and the display screen door is embedded in the hollow area of the foam door assembly.

[0081] In one embodiment, the foam door assembly is a concave structure, and the display screen door is embedded in the concave area of the foam door assembly.

[0082] It should be understood that the foam door assembly can be any structure that can be used to fix the display door and can be installed on the refrigerator body, and will not be described in detail here.

[0083] The present invention provides a camera clamping structure for a display screen door body, which realizes the clamping of the camera by the clamping block through the clamping block and the clamping piece, and the clamping block can be buckled into or detached from the clamping piece at any time, so that the camera is firmly fixed and easy to load and unload.

[0084] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and embodiments shown here.
