DETAILED DESCRIPTION

[0044] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0045] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0046] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0047] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal communication between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0048] like Figures 1 to 9 As shown, the door body provided by the present invention includes a door frame 100 , a decorative strip 200 connected to the door frame 100 , and a door panel 300 located between the door frame 100 and the decorative strip 200 .

[0049] The door frame 100 is formed by four connected frames. It includes a first adhesive surface 101 and a second adhesive surface 102 located outside the first adhesive surface 101. The second adhesive surface 102 is located closer to the edge of the door body than the first adhesive surface 101. Glue is injected into the first adhesive surface 101 to bond the door panel 300, and glue is injected into the second adhesive surface 102 to bond the decorative strip 200.

[0050] The first adhesive surface 101 and the second adhesive surface 102 are not coplanar, and there is an angle between the first adhesive surface 101 and the second adhesive surface 102. The first adhesive surface 101 and the second adhesive surface 102 are positioned and oriented in different directions to improve the firmness of the door body after assembly and to resist forces in different directions to prevent the adhesive surfaces of the door body from separating.

[0051] Specifically, the door frame 100 includes a main body 103 and a first adhesive portion 104 located inside the main body 103 . The first adhesive surface 101 is located on the side of the first adhesive portion 104 facing the door panel 300 . The second adhesive surface 102 is located on the main body 103 .

[0052] The main body 103 is a frame-like structure, which is located outside the door panel 300 and covers the door panel 300. The first adhesive portion 104 is parallel to the door panel 300. The side of the first adhesive portion 104 facing the door panel 300 is the first adhesive surface 101, which is bonded to the front surface 301 of the door panel 300.

[0053] The main body 103 includes an outer frame 103a and an insertion slot 103b located on the outer frame 103a. The second adhesive surface 102 is located within the insertion slot 103b. The insertion slot 103b is located on the side of the outer frame 103a facing the first adhesive portion 104, that is, the second adhesive surface 102 and the first adhesive surface 101 are adjacent. The decorative strip 200 is partially inserted into the insertion slot 103b, thereby bonding to the second adhesive surface 102.

[0054] By setting the second bonding surface 102 in the insertion groove 103b, on the one hand, the bonding area between the decorative strip 200 and the second bonding surface 102 can be increased, and the bonding strength between the decorative strip 200 and the door panel 300 can be improved; on the other hand, the colloid on the second bonding surface 102 can be prevented from overflowing, and when the decorative strip 200 is bonded to the first bonding surface 101, a glue layer with uniform thickness can be formed between the first bonding surface 101 and the decorative strip 200, thereby playing a good sealing role.

[0055] The outer frame 103a includes a first connecting arm 103a-1 perpendicular to the first bonding portion 104, and a second connecting arm 103a-2 extending obliquely from the first connecting arm 103a-1 toward a direction away from the first bonding portion 104. The first connecting arm 103a-1 and the second connecting arm 103a-2 form the plug-in slot 103b, and the second bonding surface 102 includes a first plane 102a located on the first connecting arm 103a-1 and a first inclined surface 102b located on the second connecting arm 103a-2.

[0056] The first connecting arm 103a-1 extends along the thickness direction of the door body, and the second connecting arm 103a-2 extends obliquely toward the decorative strip 200. There is an angle between the second connecting arm 103a-2 and the first connecting arm 103a-1 to form the insertion slot 103b.

[0057] It is understood that the inner wall of the insertion slot 103b serves as the second bonding surface 102. The inner wall of the insertion slot 103b includes a first flat surface 102a located on the first connecting arm 103a-1 and a first inclined surface 102b located on the second connecting arm 103a-2. The first flat surface 102a and the first inclined surface 102b together form the second bonding surface 102. After the decorative strip 200 is partially inserted into the insertion slot 103b, it is simultaneously bonded to the first flat surface 102a on the first connecting arm 103a-1 and the first inclined surface 102b on the second connecting arm 103a-2, thereby increasing the bonding area and improving bonding strength.

[0058] Thus, the first plane 102a is perpendicular to the first bonding surface 101, and the first inclined surface 102b and the first bonding surface 101 and the first plane 102a all have included angles, which can increase the bonding area while resisting forces in different directions.

[0059] The inserting groove 103b is provided with a tooth groove, that is, the first plane 102a and / or the first inclined surface 102b are provided with a tooth groove, thereby further increasing the bonding area between the decorative strip 200 and the second bonding surface 102 to improve the bonding strength.

[0060] Of course, in other embodiments, the first connecting arm 103a-1 forming the plug-in slot 103b may also be tilted; or a connecting arm may be added to connect the first connecting arm 103a-1 and the second connecting arm 103a-2 to form the plug-in slot 103b.

[0061] The connection point between the second connecting arm 103a-2 and the first connecting arm 103a-1 is located in the middle of the first connecting arm 103a-1. This allows the distance between the second adhesive surface 102 and the decorative strip 200 to be smaller than the distance between the first adhesive surface 101 and the decorative strip 200, thereby reducing the volume and manufacturing cost of the decorative strip 200. A gap exists between the second connecting arm 103a-2 and the fitting surface 201 along the thickness of the door. This means that the connection points between the decorative strip 200 and the door panel 300, the connection points between the decorative strip 200 and the door frame 100, and the connection points between the door frame 100 and the door panel 300 are spaced apart along the thickness of the door, thereby improving the firmness and assembly accuracy of the door after assembly. The gap between the second connecting arm 103a-2 and the fitting surface 201 also provides space for the snap-fit connection between the decorative strip 200 and the door panel 300.

[0062] The outer frame 103a further includes a third connecting arm 103a-3 extending from an end of the second connecting arm 103a-2 away from the first connecting arm 103a-1 to the first bonding portion 104. The third connecting arm 103a-3 connects the second connecting arm 103a-2 and the first bonding portion 104, thereby providing support for the second connecting arm 103a-2 and preventing the second connecting arm 103a-2 from being compressed and deformed during bonding.

[0063] The third connecting arm 103a-3 is parallel to the first connecting arm 103a-1, that is, the third connecting arm 103a-3 is perpendicular to the first adhesive portion 104. A retaining wall is provided on the side of the first adhesive portion 104 away from the third connecting arm 103a-3. The dual functions of the third connecting arm 103a-3 and the retaining wall prevent the colloid from overflowing from the first adhesive surface 101. Furthermore, the third connecting arm 103a-3 can abut against the side of the door panel 300, thereby limiting the position of the door panel 300 and improving the accuracy of door assembly.

[0064] The main body 103 is further provided with a guide slope 103c, which is used to guide the assembly of the decorative strip 200 so that the decorative strip 200 is partially inserted into the insertion groove 103b. The portion of the first connecting arm 103a-1 away from the first adhesive portion 104 is inclined to form the guide slope 103c. The inclination direction of the guide slope 103c is opposite to the inclination direction of the first inclination 102b.

[0065] A reinforcing iron 105 is further provided in the door frame 100 to improve the strength of the door frame 100. The reinforcing iron 105 is located in the outer frame 103a.

[0066] A trapezoidal frame is formed on one side of the outer frame 103a facing the first bonding portion 104. The trapezoidal frame is formed by the first connecting arm 103a-1, the second connecting arm 103a-2, the third connecting arm 103a-3, and the first bonding portion 104. The area of the trapezoidal frame is smaller than the area of the frame formed by the outer frame 103a. The dual effects of the trapezoidal frame and the reinforcing iron 105 can strengthen the structural strength of the door frame 100 and prevent deformation of the door frame 100.

[0067] It's important to note that a barrier arm 103a-4 is also provided on the side of the first connecting arm 103a-1 facing away from the second connecting arm 103a-2. This barrier arm 103a-4 is perpendicular to the first connecting arm 103a-1 and serves to positionally secure the reinforcing iron 105. The connection point between the first connecting arm 103a-1 and the second connecting arm 103a-2 coincides with the connection point between the first connecting arm 103a-1 and the barrier arm 103a-4. This arrangement of the trapezoidal frame and the reinforcing iron 105 along the thickness of the outer frame 103a further strengthens the structural strength of the door frame 100.

[0068] The decorative strip 200 includes a bonding surface 201 facing the first bonding surface 101 and a third bonding surface 202 bonded to the second bonding surface 102. The bonding surface 201 is bonded to the back surface 302 of the door panel 300, and the third bonding surface 202 is bonded to the second bonding surface 102, thereby connecting the decorative strip 200 to the door frame 100.

[0069] The decorative strip 200 includes a decorative strip body 203 and a second adhesive portion 204 extending from the decorative strip body 203 toward the second adhesive surface 102 . The bonding surface 201 is located on the side of the decorative strip body 203 facing the door panel 300 , and the third adhesive surface 202 is located on the second adhesive portion 204 .

[0070] The side of the decorative strip body 203 facing the door panel 300 is the bonding surface 201. The bonding surface 201 is directly opposite the first adhesive surface 101. The distance between the first adhesive surface 101 and the bonding surface 201 is the same as the thickness of the door panel 300. The front surface 301 of the door panel 300 is bonded to the first adhesive surface 101, and the back surface 302 of the door panel 300 is bonded to the bonding surface 201, thereby achieving assembly and fixation of the door panel 300.

[0071] The second adhesive portion 204 is perpendicular to the fitting surface 201 , and extends along the thickness direction of the door body. The second adhesive portion 204 is inserted into the insertion groove 103 b , so that the third adhesive surface 202 on the second adhesive portion 204 is bonded to the second adhesive surface 102 .

[0072] The connection point between the second connecting arm 103a-2 and the first connecting arm 103a-1 is located in the middle position of the first connecting arm 103a-1. It can be understood that the distance between the second bonding surface 102 and the decorative strip main body 201 is smaller than the distance between the first bonding surface 101 and the decorative strip main body 201, thereby reducing the extension length of the second bonding portion 204 and further reducing the volume and manufacturing cost of the decorative strip 200.

[0073] Specifically, the second adhesive portion 204 has an inserting portion 204a inserted into the inserting groove 103b, the inserting portion 204a is located at one end of the second adhesive portion 204 away from the decorative strip main body 203, the third adhesive surface 202 is located on the inserting portion 204a, and the inserting portion 204a and the inserting groove 103b are adapted to each other.

[0074] In the embodiment where the second bonding surface 102 includes the first flat surface 102a and the first inclined surface 102b, the inserting portion 204a is triangular in shape, thereby being adapted to form the inserting groove 103b with the first connecting arm 103a-1 and the second connecting arm 103a-2. The third bonding surface 202 includes a second flat surface 202a bonded to the first flat surface 102a and a second inclined surface 202b bonded to the first inclined surface 102b.

[0075] The second flat surface 202a is parallel to the first flat surface 102a on the first connecting arm 103a-1, and the second inclined surface 202b is parallel to the first inclined surface 102b on the second connecting arm 103a-2. After the insertion portion 204a is inserted into the insertion slot 103b, the second flat surface 202a adheres to the first flat surface 102a, and the second inclined surface 202b adheres to the first inclined surface 102b, thereby connecting the decorative strip 200 to the door frame 100.

[0076] The inserting portion 204a is provided with teeth and grooves, that is, the second plane 202a and / or the second inclined surface 202b are provided with teeth and grooves, thereby further increasing the bonding area between the second bonding surface 102 and the third bonding surface 202 to improve the bonding firmness.

[0077] The second bonding portion 204 further includes an elastic member 204b, which has a gap with the fitting surface 201 in the door thickness direction. The edge of the door panel 300 has a clamping portion 303, which is located between the decorative strip body 203 and the elastic member 204b.

[0078] The elastic member 204b is located on the side of the inserting portion 204a facing the decorative strip body 203. The elastic member 204b extends obliquely from the second adhesive portion 204 toward the contact surface 201. The elastic member 204b applies pressure to the side of the clamping portion 303 facing away from the contact surface 201. The side of the clamping portion 303 facing the contact surface 201 constitutes a portion of the back surface 302. Under the action of the elastic member 204b, the back surface 302 is tightly attached to the contact surface 201, thereby clamping and fixing the decorative strip 200 to the door panel 300.

[0079] The area of the fitting surface 201 is larger than the area of the clamping portion 303 , thereby preventing the decorative strip 200 from falling off the door panel 300 .

[0080] It can be understood that when the clamping portion 303 is provided at the edge of the door panel 300, the area between the clamping portion 303 and the front face 301 along the thickness direction of the door panel 300 is an empty area, and the plug-in portion 204a and the plug-in slot 103b are located in the empty area.

[0081] Of course, in other embodiments, the elastic member 204 b may not be provided, and the fitting surface 201 may be directly bonded to the back surface 302 of the door panel 300 , thereby fixing the decorative strip 200 on the door panel 300 .

[0082] The decorative strip body 203 further includes a placement plane 203a disposed opposite the fitting surface 201. The placement plane 203a is parallel to the fitting surface 201, that is, the placement plane 203a is parallel to the door panel 300. After the decorative strip 200 is clipped and fixed to the door panel 300, the door panels 300 with the decorative strip 200 can be stacked.

[0083] Reference Figure 5 The front sides 301 of the door panels 300 with the decorative strips 200 are stacked downwards, and the front sides 301 of the upper door panels 300 are overlapped with the placement plane 203a of the decorative strips 200 on the lower door panels 300. The door panels 300 are stacked neatly to reduce the space occupied by the door panels 300, and at the same time facilitate the robot to move the door panels 300 with the decorative strips 200 to assemble with the door frames 100 in the later stage.

[0084] The door panel 300 is located between the door frame 100 and the decorative strip 200 . The front surface 301 of the door panel 300 is bonded to the first bonding surface 101 , and the back surface 302 of the door panel 300 is bonded to the bonding surface 201 .

[0085] In a specific embodiment, the door panel 300 is a glass door panel. The door panel 300 includes a front glass panel, a back glass panel, and a seal connecting the front and back glass panels. The seal is disposed along the edge of the front glass panel, and a gap is provided between the front and back glass panels to form a sealed cavity. The side of the front glass panel facing away from the back glass panel is the front surface 301 of the door panel 300, and the side of the back glass panel facing away from the front glass panel is the back panel 302 of the door panel 300.

[0086] The area of the back plate glass is larger than that of the front plate glass, and the portion of the four edges of the back plate glass that extends beyond the sealing component is the clamping portion 303 .

[0087] The door body further includes a door seal 400 , which is connected to a side of the main body 103 close to the decorative strip 200 . A clearance groove 203 b is provided on the decorative strip main body 203 , and a portion of the door seal 400 is located in the clearance groove 203 b .

[0088] The main body 103 is provided with a connecting groove 103 d , and the door seal 400 is provided with a connecting portion 401 that is inserted into the connecting groove 103 d . The door seal 400 is connected to the door frame 100 through the connecting groove 103 d and the connecting portion 401 .

[0089] The connecting portion 401 is provided with an anti-slip portion. The connecting groove 103d is provided with an entrance for inserting the connecting portion 401 into the connecting groove 103d. The entrance is provided with an inclined surface. When the connecting portion 401 is inserted into the connecting groove 103d through the entrance, the anti-slip portion is compressed and contracted when it contacts the inclined surface of the entrance, allowing the anti-slip portion to enter the connecting groove 103d. After the anti-slip portion is fully inserted into the connecting groove 103d, it returns to its original position and cannot be removed from the entrance, thereby completing the connection between the door seal 400 and the door frame 100.

[0090] The trim strip body 203 is recessed to form the clearance groove 203 b , and the door seal strip 400 is partially located in the clearance groove 203 b , thereby covering the connection gap between the door frame 100 and the trim strip 200 .

[0091] The present invention also provides a refrigeration device including the above-mentioned door body. The refrigeration device includes but is not limited to a refrigerator, a freezer, etc.

[0092] The present invention also provides a door body assembly method for assembling the above-mentioned door body, which comprises the following steps:

[0093] Apply glue to the first adhesive surface 101 of the door frame 100 and the second adhesive surface 102 located outside the first adhesive surface 101;

[0094] Connecting the decorative strip 200 to the outer periphery of the door panel 300 so that the back surface 302 of the door panel 300 is in contact with the contact surface 201 of the decorative strip 200 ;

[0095] The door panel 300 with the decorative strip 200 is connected to the door frame 100 so that the front surface 301 of the door panel 300 is bonded to the first bonding surface 101 ; and the third bonding surface 202 of the decorative strip 200 is bonded to the second bonding surface 102 .

[0096] The step of “applying glue to the first adhesive surface 101 and the second adhesive surface 102 of the door frame 100” includes:

[0097] Place the door frame 100 on the transmission assembly, with the first adhesive surface 101 and the second adhesive surface 102 facing upwards;

[0098] The door frame 100 is transported to the gluing area by a transport component, and glue is applied to the first adhesive surface 101 and the second adhesive surface by an automatic gluing device.

[0099] Specifically, the transmission assembly is used to transmit the assembled door frame 100, and the transmission assembly 100 can be implemented in the form of a transmission belt or transmission rollers. When the door frame 100 is placed on the transmission assembly, the first adhesive surface 101 and the second adhesive surface 102 need to be kept facing upward, so that the automatic gluing device can apply glue on the first adhesive surface 101 and the second adhesive surface 102.

[0100] The door frame 100 is transferred to the gluing area by the transmission component, and an automatic gluing device is provided in the gluing area. Since the first bonding surface 101 and the second bonding surface 102 are both open upward, the automatic gluing device only needs to move above the first bonding surface 101 and the second bonding surface 102 to perform the gluing operation.

[0101] The first adhesive surface 101 is the upper surface of the first adhesive portion 104. When the automatic glue application device applies glue, the third connecting arm 103a-3 and the retaining wall can prevent the glue on the first adhesive surface 101 from overflowing. The second adhesive surface 102 is located in the insertion groove 103b. The automatic glue application device only needs to inject the glue into the insertion groove 103b to apply glue. The insertion groove 103b can also prevent the glue from overflowing.

[0102] Automatic gluing equipment can use a robot to apply glue. Compared with manual gluing, robot gluing can greatly improve the gluing efficiency, and can ensure the uniformity of gluing and the accuracy of gluing position, thereby improving the assembly quality of the door body.

[0103] In the statement “connecting the decorative strip 200 to the outer periphery of the door panel 300 so that the back surface 302 of the door panel 300 is in contact with the contact surface 201 of the decorative strip 200 ”:

[0104] When attaching the decorative strip 200, it is clipped onto the clipping portion 303 of the door panel 300. The clipping portion 303 is located between the decorative strip body 203 and the elastic member 204b. The elastic member 204b abuts against the side of the clipping portion 303 facing away from the decorative strip body 203. Under the action of the elastic member 204b, the back surface 302 of the door panel 300 and the contact surface of the decorative strip 200 are tightly contacted, thereby clipping and fixing the decorative strip 200 to the door panel 300. At this time, the second adhesive portion 204 is located on the side of the decorative strip body 203 facing the front surface 301 of the door panel 300.

[0105] After the connection is completed, the door panels 300 with the decorative strips 200 are stacked in sequence and placed next to the transmission assembly to facilitate subsequent assembly with the glue-coated door frame 100. When stacking, keep the front faces 301 of the door panels 300 facing downward, and the front face 301 of the upper door panel 300 overlaps the placement plane 203a of the decorative strips 200 on the lower door panel 300.

[0106] The step of “connecting the door panel 300 with the decorative strip 200 to the door frame 100 ” includes:

[0107] The door frame 100 after gluing is transferred to the assembly area by the transfer assembly;

[0108] Move the door panel 300 to the top of the door frame 100 by using a transport assembly, keeping the front side 301 of the door panel 300 facing downward;

[0109] The door panel 300 is moved downward toward the door frame 100 , so that the front surface 301 is bonded to the first bonding surface 101 , and the third bonding surface 202 is bonded to the second bonding surface 102 .

[0110] Specifically, the assembly area is located downstream of the gluing area. After the door frame 100 is glued in the gluing area, the gluing-coated door frame 100 is then transferred to the assembly area by the transfer component.

[0111] The assembly area is provided with a transport assembly, and the stacked door panels 300 with the decorative strips 200 are placed near the assembly area. When the door frame 100 arrives at the assembly area, the top door panel 300 is transported by the transport assembly and moved directly above the door frame 100, with the front face 301 of the door panel 300 facing downward.

[0112] The transport component can use a mechanical transport arm with a suction cup. The back side 302 of the stacked door panels 300 faces upward. The suction cup is attached to the back side 302 of the door panels 300 to transport the door panels 300 with the decorative strips 200, and the front side 301 of the door panels 300 can be kept facing downward.

[0113] The door panel 300 is driven to move toward the door frame 100 by the conveying assembly. When the decorative strip 200 contacts the guide slope 103c of the door frame 100, under the action of the guide slope 103c, the plug-in portion 204a can be aligned with the plug-in groove 103b, and the door panel 300 and the door frame 100 are aligned, so that the front surface 301 is bonded to the first bonding surface 101, and the third bonding surface 202 is bonded to the second bonding surface 102.

[0114] The second bonding portion 204 contacts the guide bevel 103c for alignment and assembly. Under the action of the guide bevel 103c, the second bonding portion 204 moves downward along the first connecting arm 103a-1 until the plug-in portion 204a is inserted into the plug-in groove 103b, thereby achieving bonding of the second plane 202a with the first plane 102a, and bonding of the second bevel 202b with the first bevel 102b.

[0115] The combination of the second flat surface 202a and the first flat surface 102a, and the second inclined surface 202b and the first inclined surface 102b, can increase the bonding area between the third bonding surface 202 and the second bonding surface 102, thereby ensuring the bonding strength between the third bonding surface 202 and the second bonding surface 102. Furthermore, a uniform adhesive layer can be formed between the third bonding surface 202 and the second bonding surface 102, thereby achieving a good sealing effect.

[0116] At the same time, the front side 301 of the door panel 300 is bonded to the first bonding surface 101 , and under the action of the third connecting arm 103a - 3 and the retaining wall, glue leakage can be prevented when the front side 301 is bonded to the first bonding surface 101 .

[0117] The door frame 100 and the door panel 300 are clamped together using a clamp. After the adhesive solidifies, the door frame 100, the decorative strip 200, and the door panel 300 are assembled. Finally, the door seal 400 is attached to the door frame 100, and the connecting portion 401 is inserted into the connecting groove 103d to cover the connecting gap between the door frame 100 and the decorative strip 200.

[0118] It should be noted that the automatic gluing equipment is fast in gluing, and after the gluing is completed, the door frame 100 is immediately transferred to the assembly area, and the door panel 300 with the decorative strip 200 is transported by the conveying component and assembled with the door frame 100. The assembly speed is fast, so hot melt glue is applied to the first bonding surface 101 and the second bonding surface 102. The hot melt glue solidifies quickly, and the bonding is firm and not easy to deform.

[0119] To sum up, the door body provided by the present invention can be assembled automatically. The assembly method adopts a process of assembly in the vertical direction, which changes the assembly sequence of the original door body, realizes automatic glue injection and automatic bonding, and greatly improves the door body assembly efficiency and degree of automation.
