Description

Technical Field

[0001] The present application belongs to the technical field of household appliances, and specifically relates to a door structure and electrical equipment. Background Art

[0002] The way to open a drop-down door is to rotate it downward. Since the door itself has gravity, it tends to fall during the process of rotating it downward. Therefore, a hovering structure needs to be set on the drop-down door so that the door can remain hovering at the angle specified by the user during the opening process to meet the user's usage needs.

[0003] In the related art, the suspension structure of the drop-down door body is complex and has low reliability, and the door body is easy to fall down, which affects the user experience. Summary of the invention

[0006] In the door structure provided by the present application, when the access opening needs to be opened, the door is operated to rotate in the direction away from the frame. Since the friction member and the friction part are in frictional contact during the rotation of the door relative to the frame, the elastic member will be stretched accordingly to generate tension. Therefore, when the door is rotated to a certain angle, static friction will be generated between the friction member and the friction part due to the relative movement trend, and the elastic member has tension. The tension of the elastic member plus the torque of the friction force can balance the torque of the door weight, so that the door can remain in a suspended state at any angle, and is not easy to rebound or fall. The structure is simple and reliable to ensure the user experience.

DETAILED DESCRIPTION

[0033] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0034] The way to open a drop-down door is to rotate it downward. Since the door itself has gravity, the door tends to fall down during the downward rotation. Therefore, a suspension structure needs to be provided on the drop-down door so that the door can remain suspended at a user-specified angle during the opening process to meet the user's usage requirements. However, in the related art, the suspension structure of the drop-down door is complex and has low reliability, so that the door is easy to fall down during the opening process and cannot remain suspended at a specified angle, affecting the user's usage experience.

[0035] In order to improve the problems existing in the related technology, the present application provides a door structure and electrical equipment. During the rotation of the door body relative to the frame, the friction resistance and elastic force generated between the door body and the frame are utilized to balance the weight of the door body, so that the door body can remain hovering at any angle. The structure is simple and reliable, which can meet the user's usage needs and improve the user experience.

[0036] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0037] See also Figure 1-Figure 7The embodiment of the present application provides a door body structure 10. During the rotation of the door body 210 relative to the frame body 100, friction resistance and elastic force balanced with the gravity of the door body 210 will be generated between the door body 210 and the frame body 100, so that the door body 210 can remain hovering at any angle to meet the user's usage needs.

[0038] See also Figure 1 , Figure 6 and Figure 7 The door structure 10 of the embodiment of the present application includes a frame 100, a door assembly 200 and an elastic member 300. Among them, the frame 100 is provided with a take-in and put-out port 110, through which the user can take and put items to the door assembly 200, and the frame 100 is provided with a rotating shaft 120 and a friction part 130. The door assembly 200 includes a door body 210, a connecting member 220 and a friction member 230, the connecting member 220 and the friction member 230 are connected to the door body 210, and the connecting member 220 is rotatably connected to the rotating shaft 120 so that the door body 210 can be rotated relative to the frame 100 to open and close the take-in and put-out port 110. Obviously, the take-in and put-out port 110 can be opened by rotating the door body 210 downward with its back to the frame 100, and the take-in and put-out port 110 can be closed by rotating the door body 210 upward toward the frame 100, and the rotation angle of the door body 210 when the take-in and put-out port 110 is fully opened is 90° (such as Figure 7 When the door body 210 completely closes the access opening 110, the rotation angle is 0° (as shown in FIG. Figure 6 As shown in FIG. 1 , the rotation angle range of the door body 210 is 0° to 90°. When the door body 210 rotates relative to the frame 100, the friction member 230 is in friction contact with the friction portion 130. The elastic member 300 is connected between the frame 100 and the door assembly 200, that is, when the door body 210 rotates relative to the frame 100, the elastic member 300 will extend and generate tension.

[0039] In the door structure 10 proposed in the embodiment of the present application, when the access port 110 needs to be opened, the door 210 is operated to rotate in the direction away from the frame 100. Since the friction member 230 is in frictional contact with the friction portion 130 during the rotation of the door 210 relative to the frame 100, the elastic member 300 will be stretched accordingly to generate tension. Therefore, when the door 210 rotates to any angle between 0° and 90°, static friction will be generated between the friction member 230 and the friction portion 130 due to the relative motion trend, and the elastic member 300 has tension. The tension of the elastic member 300 plus the torque of the friction force can balance the torque of the weight of the door 210, so that the door 210 can remain in a suspended state at any angle and is not easy to fall off. The structure is simple and reliable, ensuring the user experience.

[0040] It should be noted that the technical problem to be solved by the present application is to ensure that the door body 210 can be kept in a hovering state at any angle during the process of opening the door body 210. Of course, whether the door body 210 is opened or closed, the hovering principle described above is applicable in this process. However, the hovering principle is not applicable when the rotation angle of the door body 210 is 0° or 90°, that is, when the door body 210 is in a state of fully opening or closing the access port 110. When the rotation angle of the door body 210 is 0° or 90°, other structures are required to keep the door body 210 hovering.

[0041] In some embodiments, see Figure 1 and Figure 5 The friction part 130 can be an arc-shaped protrusion provided on the frame 100. The protrusion is integrally formed on the frame 100 and is an arc-shaped structure protruding from the surface of the frame 100. The protrusion protruding from the frame 100 can be conveniently connected with the friction member 230, thereby frictionally contacting with the friction member 230 to form the above-mentioned static friction force. The movement trajectory of the door body 210 during the rotation process is an arc-shaped. Since the friction member 230 is connected to the door body 210 and rotates with the door body 210, the movement trajectory of the friction member 230 is also an arc-shaped. In order to ensure that the friction part 130 is always in contact with the friction member 230 during the rotation of the door body 210, the shape of the protrusion is set to an arc-shaped structure. Of course, the convex curvature corresponds to the motion trajectory of the friction member 230 to ensure that the friction portion 130 and the friction member 230 always maintain friction contact during the rotation of the door body 210, so that when the door body 210 stops at any angle, static friction can be generated between the friction portion 130 and the friction member 230 to offset the gravity of the door body 210, so that the door body 210 can maintain a suspended state. The central angle of the arc structure is slightly less than 90, so that when the door body 210 is in a fully opened or closed state, the door body 210 can maintain the door body 210 through other structures.

[0042] In some embodiments, the friction portion 130 and the friction member 230 can be made of a metal material with a relatively high roughness, such as steel, aluminum alloy, etc., so that a relatively large friction force can be generated between the friction portion 130 and the friction member 230, while the friction portion 130 and the friction member 230 also have a relatively high rigidity and are not easily worn, thereby extending the service life of the door body structure 10.

[0043] It should be explained that, as mentioned above, since the above-mentioned hovering principle is not applicable to the situation when the rotation angle of the door body 210 is 0° or 90°, the movement trajectory range of the above-mentioned friction member 230 also does not include the situation when the rotation angle of the door body 210 is 0° or 90°.

[0044] In some embodiments, in order to ensure that the door body 210 can remain suspended when the rotation angle of the door body 210 is 0° or 90°, that is, when the door body 210 is in a fully opened or closed state of the access port 110, a first recess 140 and a second recess 150 are further provided on the frame body 100. The first recess 140 and the second recess 150 are respectively provided on the outer sides of the two ends of the friction part 130, so that the plane formed by the first recess 140 and the rotating shaft 120 and the plane formed by the second recess 150 and the rotating shaft 120 are arranged vertically, and the friction member 230 can be detachably provided in the first recess 140 or the second recess 150.

[0045] The first recess 140 or the second recess 150 is a structure recessed in the frame 100, so it can accommodate the friction member 230. Since the first recess 140 and the second recess 150 are respectively arranged on the outer sides of the two ends of the friction member 130, and the friction member 130 includes a protrusion corresponding to the movement trajectory of the friction member 230 (the movement trajectory range of the friction member 230 here does not include the situation when the rotation angle of the door body 210 is 0° or 90°), it is obvious that the first recess 140 or the second recess 150 is the position of the friction member 230 when the rotation angle of the door body 210 is 0° and 90°, respectively. That is, when the rotation angle of the door body 210 is 0°, the friction member 230 is located in the first recess 140. When the access port 110 needs to be opened, the door body 210 is rotated away from the frame body 100, and the friction member 230 is disengaged from the first recess 140 and in friction contact with the friction member 230. When the rotation angle of the door body 210 is 90°, the friction member 230 moves from the friction portion 130 to the second recess 150.

[0046] Next, the hovering principle of the door body 210 when the rotation angle of the door body 210 is 0° and 90° is introduced: when the rotation angle of the door body 210 is 0°, the friction member 230 is located in the first recess 140. At this time, the elongation of the elastic member 300 is 0, and only the first recess 140 provides a supporting force to the friction member 230. The torque of the supporting force balances the torque of the weight of the door body 210, so that the door body 210 maintains a hovering state; when the rotation angle of the door body 210 is 90°, the elastic member 300 reaches the maximum elongation, and the torque of the pulling force of the elastic member 300 will be greater than the torque of the weight of the door body 210. Since the friction member 230 is located in the second recess 150 at this time, the torque of the weight of the door body 210 plus the torque of the supporting force of the second recess 150 can balance the torque of the pulling force of the elastic member 300, so that the door body 210 maintains a hovering state. That is, when the rotation angle of the door body 210 is 0°, 90°, or between 0° and 90°, the door body 210 can maintain force balance, that is, the door body 210 can be in a hovering state.

[0047] The present application achieves balance by supporting the first recess 140 or the second recess 150 when the door body 210 is fully opened or fully closed at the access opening 110, rather than using the static friction and the tension of the spring, which is safer and more reliable.

[0048] In some embodiments, see Figure 3 and Figure 5 Since the friction member 230 needs to move back and forth between the first recess 140 or the second recess 150 and the friction member 130 during the process of the door body 210 moving from opening to closing the access opening 110, or from closing to opening the access opening 110, and since the first recess 140 or the second recess 150 is recessed in the frame body 100, the inner side wall of the first recess 140 or the second recess 150 will restrict the movement of the friction member 230, resulting in more difficult movement of the friction member 230. Therefore, in order to make the movement of the friction member 230 smoother, a first guide slope 231 is provided on the circumferential surface of the friction member 230; and a second guide slope 141 matching the first guide slope 231 is provided on the side walls of the first recess 140 and the second recess 150.

[0049] When the friction member 230 moves out of or enters the first recess 140, the first guide slope 231 and the second guide slope 141 will slide relative to each other, that is, the friction member 230 can slide in or out of the first recess 140, so that the movement of the friction member 230 is smoother. Similarly, when the friction member 230 moves out of or enters the second recess 150, the first guide slope 231 and the second guide slope 141 will also slide relative to each other, so that the movement of the friction member 230 is smoother.

[0050] In some embodiments, since the friction part 130 protrudes from the frame 100, the outer side wall of the friction part 130 will also form a certain restriction on the movement of the friction member 230. In order to further improve the smoothness of the movement of the friction member 230, the side wall of the friction part 130 is provided with a third guide slope 131 that matches the first guide slope 231. When the friction member 230 moves out of or enters the friction part 130, the first guide slope 231 and the third guide slope 131 will slide relative to each other, that is, the friction member 230 can slide in or out of the friction part 130, so that the movement of the friction member 230 is smoother.

[0051] In some embodiments, see Figure 1 A friction portion 130 is provided on the outer side of the side in the width direction of the frame body 100, and the friction member 230 is connected to the side in the width direction of the door body 210. The friction member 230 is provided on the outer side of the friction portion 130, so that the friction member 230 and the friction portion 130 can be in friction contact with each other.

[0052] Of course, in other embodiments, the friction portion 130 may be disposed on the outside of the friction member 230 , as long as the friction member 230 and the friction portion 130 are disposed opposite to each other, and there is no limitation to this.

[0053] In some embodiments, see Figure 2 The friction member 230 is connected to the connecting member 220. The friction member 230 and the connecting member 220 can be connected together by welding, screwing, etc., or can be integrally formed to form a whole, so as to enhance the structural strength of the friction member 230 and the connecting member 220 as a whole.

[0054] Of course, in other embodiments, the friction member 230 may also be directly connected to the door body 210 , and this is not limited.

[0055] In some embodiments, see Figure 1 and Figure 2 The door body 210 includes an inner door body 211 and an outer door body 212, the outer door body 212 is covered on the inner door body 211, and the connecting member 220 is arranged between the side of the inner door body 211 in the width direction and the side of the outer door body 212 in the width direction, that is, the connecting member 220 is connected to both the outer door body 212 and the inner door body 211, which can enhance the connection strength between the connecting member 220 and the door body 210, thereby making the connection between the door body 210 and the frame 100 more stable. In addition, in order to facilitate the installation and disassembly of the connection, the connecting member 220 can be connected to the outer door body 212 and the inner door body 211 by a detachable connection method such as screw connection and clamping.

[0056] In some embodiments, the connector 220 includes a first connector 221 and a second connector 222. The first connector 221 is connected to the side of the inner door body 211 in the width direction, and the second connector 222 is connected to the side of the outer door body 212 in the width direction. The first connector 221 and the second connector 222 can be connected together by welding, screwing, etc., or can be integrally formed to form a whole, so as to enhance the structural strength of the connector 220 as a whole.

[0057] In some embodiments, the connecting member 220 further includes a third connecting portion 223. The third connecting portion 223 is provided with a rotating portion 224, and the rotating shaft 120 is rotatably connected to the rotating portion 224.

[0058] The third connection part 223 can be connected to the side of the second connection part 222 close to the frame 100 to facilitate the connection between the rotating shaft 120 and the rotating part 224, and the third connection part 223 and the first connection part 221 are staggered to avoid mutual interference. The third connection part 223 and the second connection part 222 can be connected together by welding, screwing, etc., or can be integrally formed to form a whole to enhance the overall structural strength of the connector 220.

[0059] The rotating part 224 can be a groove structure with an opening facing downward, and the rotating shaft 120 is arranged in the groove structure. Two clips 224a are relatively arranged on the opening side of the groove structure. The two clips 224a are jointly supported on the rotating shaft 120 to limit the rotating shaft 120, thereby ensuring the connection stability between the door body 210 and the frame body 100 and preventing the rotating shaft 120 from falling off from the groove structure.

[0060] Of course, in other embodiments, the rotating portion 224 may also be a hole-shaped structure, and the rotating shaft 120 may be movably assembled in the hole-shaped structure, and there is no limitation to this.

[0061] In some embodiments, the friction member 230 is connected to the third connection portion 223. Since the third connection portion 223 is connected to the side of the second connection portion 222 close to the frame 100, the friction member 230 is also disposed on the third connection portion 223, which facilitates the connection between the friction member 230 and the friction portion 130.

[0062] See also Figure 2-Figure 4 The third connecting portion 223 is provided with an assembly portion 226, and the friction member 230 includes a friction segment 232 and a fixed segment 233. The friction segment 232 contacts the friction portion 130, and the fixed segment 233 is connected to the assembly portion 226 to achieve the connection between the friction member 230 and the connecting member 220. Specifically, the assembly portion 226 can be a hole-shaped structure or a groove-shaped structure, and the assembly portion 226 is provided with an internal thread, and the fixed segment 233 is screwed into the assembly portion 226 to facilitate the installation or removal of the friction member 230.

[0063] In some embodiments, see Figure 5 The frame 100 is connected with a mounting seat 160, which is connected to the side of the frame 100 in the width direction. The rotating shaft 120 and the friction part 130 are both arranged on the side of the mounting seat 160 facing away from the frame 100, so that the rotating shaft 120 can be connected to the rotating part 224, and the friction part 130 can be in friction contact with the friction member 230. The mounting seat 160 can be connected to the frame 100 by a detachable connection method such as screw connection and clamping, so as to facilitate the installation or removal of the mounting seat 160.

[0064] In some embodiments, see Figure 5 and Figure 7 One or more rotatable friction wheels 170 are disposed on the mounting seat 160 , one end of the elastic member 300 is connected to the frame 100 , the middle portion of the elastic member 300 bypasses the friction wheel 170 , and the other end of the elastic member 300 is connected to the door body assembly 200 .

[0065] Since the middle part of the elastic member 300 bypasses the friction wheel 170, when the door body 210 rotates, the elastic member 300 will also generate friction with the friction wheel 170 during the extension process. The torque of the friction force between the elastic member 300 and the friction wheel 170 can further balance the torque of the weight of the door body 210, thereby enhancing the reliability of the hovering function of the door body 210.

[0066] Furthermore, when the frame 100 is applied to the product, it will be covered by the outer shell, and the door 210 is outside the outer shell. If the elastic member 300 is directly connected to the frame 100 and the door 210, most of the elastic member 300 will be exposed to the outside, affecting the aesthetics of the product. However, since the friction wheel 170 can change the direction of the force, most of the elastic member 300 can be hidden in the outer shell, and the middle part of the elastic member 300 can be bypassed by the friction wheel 170 according to the needs to change the direction of the force, so that only a small part of the elastic member 300 extends out of the outer shell and is connected to the door assembly 200, ensuring the aesthetics of the product.

[0067] One, two or more friction wheels 170 may be provided. When the number of friction wheels 170 is greater than one, the middle portion of the elastic member 300 bypasses each friction wheel 170. The more friction wheels 170 there are, the greater the friction force between the elastic member 300 and the friction wheels 170. The number of friction wheels 170 may be set according to actual conditions and is not limited thereto.

[0068] In some embodiments, see Figure 1 and Figure 7 , the other end of the elastic member 300 is connected to the connecting member 220 to facilitate the installation and removal of the elastic member 300. Specifically, the connecting member 220 is provided with a hook portion 225 to connect the elastic member 300. That is, the elastic member 300 is hung on the hook portion 225 to achieve connection with the connecting member 220. The hook portion 225 is provided on a side of the connecting member 220 close to the frame 100 to facilitate the elastic member 300 to be hung on the hook portion 225.

[0069] Of course, a hook 180 may also be provided on the frame 100 , so that one end of the elastic member 300 is hung on the hook 180 to achieve the connection between the elastic member 300 and the frame 100 .

[0070] In some embodiments, at least part of the elastic member 300 is elastic. That is, the elastic member 300 may be partially elastic or fully elastic. As long as part of the elastic member 300 is elastic, when the door body 210 rotates, the elastic member 300 will generate a certain pulling force. Of course, the more elastic parts on the elastic member 300 are, the greater the pulling force that the elastic member 300 can generate, and thus the greater the pulling torque that can be used to balance the weight torque of the door body 210. Therefore, the setting range of the elastic part on the elastic member 300 can be set according to actual conditions, and there is no limitation on this.
