In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0025] Existing lid opening devices, such as cooking devices, usually use hinge components to achieve a rotatable connection between the lid and the base. However, during use, the lid is only limited by its own gravity and friction after it is opened. In the event of strong winds or accidental touch, the lid may close quickly, posing the risk of falling.

[0026] The hinge assembly provided in the present application can be used for equipment with upper and lower covers, such as cooking equipment, etc. Among them, the cooking equipment may include an oven, a microwave oven, an electric rice cooker, etc., and the present application will be described by taking an oven as an example. The hinge assembly provided in the present application can realize the hovering function of the bracket and the structural parts, which can reduce the risk of the hinge assembly closing quickly and falling down in the event of strong winds or accidental touch, thereby improving the safety of the hinge assembly and the cooking equipment.

[0027] This application first proposes a hinge assembly, such as Figure 1 and Figure 2 As shown, Figure 1 It is a structural schematic diagram of an embodiment of a hinge assembly of the present application; Figure 2 yes Figure 1 Schematic diagram of the exploded structure of the hinge assembly of the embodiment. The hinge assembly includes a first bracket 10, a second bracket 20, a connecting member 30 and an elastic member 40, wherein the first bracket 10 is used to connect with the first structural member; the second bracket 20 is used to connect with the second structural member, the first bracket 10 is rotatably connected to the first end A of the second bracket 20 through the first rotating shaft 50, so that the first structural member and the second structural member have an open state and a closed state; the connecting member 30 is connected to the first bracket 10; the connection point B between the first bracket 10 and the connecting member 30 and the connection point C of the first rotating shaft 50 on the first bracket 10 are arranged at intervals; the two ends of the elastic member 40 are respectively connected to the second end D of the second bracket 20 and the connecting member 30, and the elastic member 40 provides a rebound force for the connecting member 30 and the first bracket 10 toward the second end D of the second bracket 20, so as to drive the first structural member to have a tendency to switch to the open state.

[0028] The first bracket 10 is provided with a first mounting hole, and the first rotating shaft 50 is connected in the first mounting hole; the connection point C of the first rotating shaft 50 on the first bracket 10 refers to the first mounting hole. In this embodiment, the connection point B between the first bracket 10 and the connecting member 30 and the connection point C of the first rotating shaft 50 on the first bracket 10 are arranged at intervals, so that when the first bracket 10 rotates relative to the second bracket 20 with the first rotating shaft 50 as the rotating axis, the end of the connecting member 30 connected to the first bracket 10 is driven to rotate relative to the second bracket 20 around the outer periphery of the first rotating shaft 50.

[0029] Among them, the first structural member and the second structural member have an open state and a closed state, which means that when the first bracket 10 rotates in two opposite directions relative to the second bracket 20, for example, clockwise and counterclockwise, the first structural member is driven to rotate in two opposite directions relative to the second structural member to achieve an open state, a closed state and switching between the two.

[0030] The relative movement promoted in the present application includes relative movement of both or either of the two moving parts, and the relative movement includes opposite movement or opposite movement.

[0031] In this embodiment, the first bracket 10 is rotatably connected to the first end A of the second bracket 20, so that the first structural member connected to the first bracket 10 and the second structural member connected to the second bracket 20 can rotate relative to each other, so that the first structural member and the second structural member have an open state and a closed state; further, the connecting member 30 is respectively connected to the first bracket 10 and one end of the elastic member 40, and the connection point B between the first bracket 10 and the connecting member 30 and the connection point C of the first rotating shaft 50 on the first bracket 10 are arranged at intervals, so that when the first bracket 10 rotates relative to the second bracket 20, the connecting member 30 connected to the first bracket 10 can be driven One end moves relative to the second bracket 20 around the outer circumference of the first rotating shaft 50; and the other end of the elastic member 40 is connected to the second end D of the second bracket 20, so that when the first bracket 10 drives one end of the connecting member 30 to rotate relative to the second bracket 20 along the first rotating shaft 50, the connecting member 30 stretches the elastic member 40, and the elastic member 40 provides a rebound force toward the second end D of the second bracket 20 for the connecting member 30 and the first bracket 10, so that the first bracket 10 not only needs to overcome the gravity and rotational friction of itself and the first structural member, but also needs to overcome the additional rebound force of the elastic member 40 to continue to rotate, thereby driving the first structural member to have a tendency to switch to the open state. Therefore, this embodiment can prevent the tendency of the first bracket 10 and the second bracket 20, and the first structural member and the second structural member to switch to a closed state through the rebound force of the elastic member 40, and the gravity moment and the elastic tension moment of the first bracket are balanced under the action of friction, and the first bracket is in a suspended state, thereby reducing the risk of the hinge assembly closing quickly and falling when encountering strong winds or accidental touches, thereby improving the safety of the hinge assembly and the cooking equipment.

[0032] For example, in one application scenario, the first structural member may be a cover of an oven, and the second structural member may be a base of the oven, a baking cavity is formed on the base, and when the cover moves relative to the base in a counterclockwise direction, the oven switches to a closed state, and when the cover moves relative to the base in a clockwise direction, the oven switches to a clocked-in state. When the cover moves relative to the base in a counterclockwise direction, the first bracket 10 rotates relative to the second bracket 20 in a counterclockwise direction, and the first bracket 10 drives the end of the connecting member 30 connected to the first bracket 10 to move relative to the second bracket 20 around the outer periphery of the first rotating shaft 50; during this movement, the connecting member 30 stretches the elastic member 40, and the elastic member 40 provides a rebound force toward the second end D of the second bracket 20 for the connecting member 30, the first bracket 10, and the cover, so that the first bracket 10 and the cover not only need to overcome their own gravity and rotational friction, but also need to overcome the rebound force of the elastic member 40 to continue to rotate, so that the cover can be driven to have a tendency to switch to an open state. Furthermore, the gravity moment and the elastic pulling force acting on the first bracket reach a balance under the action of the friction force, and the first bracket is in a suspended state.

[0033] In some embodiments, a first sliding groove 31 is provided on the connecting member 30, and the hinge assembly also includes: a first connecting shaft 60, the end of the first connecting shaft 60 is slidably connected in the first sliding groove 31 along the extension direction Y of the elastic member 40, and one end of the elastic member 40 is connected to the middle part of the first connecting shaft 60.

[0034] Among them, the end of the first connecting shaft 60 is slidably connected in the first sliding groove 31, and the elastic member 40 is connected to the middle part of the first connecting shaft 60, which not only reduces the risk of the elastic member 40 falling off the first connecting shaft 60 along the axial direction of the first connecting shaft 60, but also makes the rebound force of the elastic member 40 on the connecting shaft 60 uniform, thereby improving the working stability and structural stability of the hinge assembly.

[0035] In this embodiment, the elastic member 40 is slidably connected to the connecting member 30 by the first connecting shaft 60, and the first connecting shaft 60 is slidably connected to the first sliding groove 31 of the connecting member 30 along the expansion and contraction direction Y of the elastic member 40, so that in the initial rotation stage of the first bracket 10 switching from the open state to the closed state relative to the second bracket 20, the first connecting shaft 60 does not move relative to the second bracket 20, all the pulling force of the elastic member 40 is borne by the lower second bracket 20, the elastic member 40 does not generate a rebound force, the first sliding groove 31 of the connecting member 30 is not affected by the pulling force of the elastic member 40, and the first bracket 10 and the first structural member are only affected by their own gravity and the friction force of the hinge. At this stage, since the cover is not pulled by the elastic member 40, it is relatively easy to operate.

[0036] In some embodiments, when the angle a between the first bracket 10 and the second bracket 20 is a first angle, the first structure and the second structure are in an open state, that is, the hinge assembly is in an open state; when the angle a between the first bracket 10 and the second bracket 20 is a second angle, the first structure and the second structure are in a closed state, that is, the hinge assembly is in a closed state; when the angle a between the first bracket 10 and the second bracket 20 is a third angle, the first connecting shaft 60 abuts against the inner wall of the first slide groove 31 close to the second end D of the second bracket 20. If the angle a continues to decrease, the connecting shaft 60 will stretch the elastic member 40 so that the elastic member 40 generates a rebound force. Among them, the third angle is smaller than the first angle and larger than the second angle.

[0037] In an application scenario, such as Figure 1 As shown, when the angle a between the first bracket 10 and the second bracket 20 is 90°, the first bracket 10 and the second bracket 20, and the cover body and the base body are in an open state. As the first bracket 10 and the cover body continue to rotate counterclockwise, because the first connecting shaft 60 slides relative to the first sliding groove 31, when the connecting member 30 rotates relative to the second bracket 20, the first connecting shaft 60 may not be displaced with the second bracket 20, and the elastic member 40 will not be stretched by the first connecting shaft 60, and no rebound force will be generated, so that the first bracket 10 and the cover body can rotate only by overcoming gravity and rotational friction, thereby reducing the operating force required in the initial rotation stage of closing the cover, and improving the convenience and portability of starting and closing; as shown in FIG. Figure 3 As shown, until the angle a between the first bracket 10 and the second bracket 20 is 50°, the first connecting shaft 60 abuts against the inner wall of the bottom of the first sliding groove 31. Figure 4 and Figure 5 As shown, the first bracket 10 and the cover body continue to rotate counterclockwise, and the angle a between the first bracket 10 and the second bracket 20 continues to decrease. The connecting member 30 will drive the first connecting shaft 60 to move away from the second end D of the second bracket 20 along the telescopic direction Y of the elastic member 40, so that the elastic member 40 generates a rebound force toward the second end D away from the second bracket 20, so that the first bracket 10 and the cover body not only need to overcome their own gravity and rotational friction, but also need to overcome the additional rebound force of the elastic member 40 to continue to rotate, so that the cover body can be driven to have a tendency to change to the open state. The gravity moment and elastic pulling force of the first bracket 10 are balanced under the action of friction, and the upper cover is in a suspended state. At this stage, the user needs to provide force to close the upper cover, which can reduce the risk of the cover falling quickly.

[0038] In other embodiments, the values ​​of the above-mentioned angles can be adjusted according to the specific requirements of the product.

[0039] In some embodiments, the hinge assembly also includes: a second rotating shaft 70; the connecting member 30 is rotatably connected to the first bracket 10 through the second rotating shaft 70, and the first sliding groove 31 is a first straight groove extending along the first direction; wherein the first direction is the arrangement direction between the connection point of the second rotating shaft 70 and the first straight groove.

[0040] The connecting member 30 of the present embodiment is rotatably connected to the first bracket 10, so that when the first bracket 10 rotates relative to the second bracket 20, the connecting member 30 can rotate synchronously with the first bracket 10, thereby reducing the risk of the connecting member 30 stretching the first connecting shaft 60 and thus stretching the elastic member 40; and the first sliding groove 31 on the connecting member 30 is a straight groove extending along the arrangement direction between the connection point of the second rotating shaft 70 and the first sliding groove 31, which can enable the connecting shaft to slide smoothly in the first sliding groove 31 along the telescopic direction Y of the elastic member 40.

[0044] In this embodiment, a limiting groove for limiting the movement of the first connecting shaft 60, namely, a second straight groove 21, is provided on the second bracket 20, which can improve the stability of the movement of the first connecting shaft 60, and the extension direction of the second straight groove 21 is consistent with the extension direction of the first straight groove, and the extension length of the second straight groove 21 is greater than the extension length of the first straight groove, so as to reduce the interference of the second bracket 20 on the movement of the first connecting shaft 60, thereby improving the stability of the hinge assembly.

[0045] In an application scenario, such as Figure 3 As shown, when the angle a between the first bracket 10 and the second bracket 20 is the third angle, the first connecting shaft 60 abuts against the inner wall of the bottom of the first sliding groove 31. Figure 4As shown, the first bracket 10 and the cover body continue to rotate counterclockwise, the angle a between the first bracket 10 and the second bracket 20 continues to decrease, and the connecting member 30 drives the first connecting shaft 60 to move away from the second end D of the second bracket 20 along the expansion and contraction direction Y of the elastic member 40, thereby increasing the distance between the first connecting shaft 60 and the bottom of the second straight groove 21; the first bracket 10 and the cover body continue to rotate counterclockwise, the angle a between the first bracket 10 and the second bracket 20 continues to decrease, and the distance between the first connecting shaft 60 and the bottom of the second straight groove 21 continues to increase, until the angle a between the first bracket 10 and the second bracket 20 is 0°, and the cover body and the seat body are in a closed state, as shown in FIG. Figure 5 shown.

[0046] Among them, when the angle a between the first bracket 10 and the second bracket 20 is 50°, the distance between the connecting shaft 60 and the bottom of the second straight groove 21 can be greater than or equal to zero; when the angle a between the first bracket 10 and the second bracket 20 is 0°, the distance between the connecting shaft 60 and the top of the second straight groove 21 can be greater than or equal to zero.

[0062] like Figure 1 As shown, Figure 1 As shown, the first bracket 10 and the second bracket 20, and the cover body and the base body are in an open state, and the limiting portion 11 on the first bracket 10 abuts against the end surface of the first end of the bottom wall of the second bracket 20, so that the first bracket 10 will not continue to rotate relative to the second bracket 20 in the clockwise direction to maintain the open state, so that the center of gravity of the first bracket 10 will not continue to move toward the second end D of the second bracket 20, which can reduce the operating force in the initial rotation stage of switching from the open state to the closed state and improve the convenience of operation.

[0063] In the present application, the front stage state of closing the cover (for example, the angle a is 90° to 50°): the first bracket 10 drives the connecting member 30 to rotate relative to the second bracket 20, and the first connecting shaft 60 slides in the first slide groove 31 of the connecting member 30. At this time, the first connecting shaft 60 is hung at the bottom of the second straight groove 21 of the second bracket 20, and all the pulling force of the elastic member 40 is borne by the lower second bracket 20. The first slide groove 31 of the connecting member 30 is not affected by the pulling force of the elastic member 40. The first bracket 10 and the first structural member are only affected by their own gravity and the friction force of the hinge. At this stage, closing the cover is not pulled by the elastic member 40, so it is relatively easy to operate. The latter stage of the cover closing action (for example, the angle a is 50° to 0°): the first bracket 10 rotates to pull the connecting member 30 to move, and the first connecting shaft 60 moves to the bottom of the first slide groove 31. During this process, the first connecting shaft 60 slides in the second straight groove 21, and the tension of the elastic member 40 is fully transmitted to the first bracket 10 through the connecting member 30. The gravity moment and the elastic tension moment of the first bracket 10 reach a balance under the action of friction, and the upper cover is in a suspended state. At this stage, the user needs to provide force to close the upper cover, which can reduce the risk of the cover falling off quickly.

[0064] The present application further proposes a cooking device such as Figure 6As shown, the cooking device includes: a base 32, a cover 31 and a hinge assembly 23. The base 32 forms a cooking cavity with an opening. The cover 31, as a first structural member, is hinged to the base 32, as a second structural member, through a hinge assembly 23, and opens and closes at the opening. The hinge assembly 23 is any one of the hinge assemblies in the above-mentioned hinge assembly embodiments.

[0065] The hinge assembly of the present application has a hovering function, which enables the cover body 31 to be effortless in the front section of the cover closing action (convenient for normal cover closing), and to be able to hover in the rear section of the cover closing action (to prevent rapid falling). The first bracket 10 is added with a connecting member 30 and an elastic member 40, the elastic member provides a pulling force, and then through the conversion of the connecting member 30, a resistance matching the change of its own gravity is applied to the first bracket 10, thereby achieving the cover body 31 being effortless in the front section of the cover closing action, and being able to hover in the rear section of the cover closing action.

[0066] The above are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
