Description

Technical Field

[0001] The present invention relates to the technical field of storage devices, and more particularly to a housing and a storage device. Background Art

[0002] In the related art, for the assisted opening mechanism of a refrigerator, the force applied to the door body is usually a continuous and constant force, while the force required to open the refrigerator door is variable. When the refrigerator door is fully closed, at the beginning of opening the door, the force required to open the door needs to overcome the suction force of the door seal magnetic strip, the negative pressure inside the door, the force brought by the self-locking mechanism, and the static friction at positions such as the door hinge. When the door is opened to a certain angle, the force required to open the door will drop sharply, only including the force brought by the self-locking mechanism and the dynamic friction at positions such as the door hinge. However, the force applied by the assisted opening mechanism is fixed, which leads to an excessive force applied in the later stage of opening the door, easily causing the door body to bounce open, and moreover, making the power of the assisted opening mechanism relatively large. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art, namely, the relatively large power of the assisted opening mechanism in storage devices such as refrigerators, which affects the opening effect.

[0004] To this end, a first aspect of the present invention provides a housing.

[0005] A second aspect of the present invention provides a storage device.

[0006] In view of this, according to the first aspect of the present invention, a housing is provided, including: a first body; a second body rotatably provided on the first body; a gear rotatably provided on the second body; a first rack engaged with the gear, one end of the first rack facing the first body; a second rack engaged with the gear, a first tooth portion of the first rack and a second tooth portion of the second rack being oppositely arranged; and a power assembly provided on the first body, the power assembly being configured to drive the second rack to move away from the first body.

[0007] The housing proposed by the present invention includes a first body, a second body, a first rack, a gear, a second rack, and a power assembly. The power assembly is disposed on the first body, and the gear is disposed on the second body. The first gear and the second gear are respectively disposed on both sides of the gear and are engaged with the gear. When the second rack moves away from the first body, the gear rotates and drives the first rack to move towards the first body. Thus, the gear receives a force exerted by the second rack, and the first rack abuts against the first body, causing the gear to receive a force exerted by the first rack. Therefore, the gear receives two forces, and the second body receives two forces. Among them, the force exerted by the second rack on the gear is equal to the output of the power assembly. Therefore, the force received by the second body is greater than the output force of the power assembly. Thus, in the first stage, the output force of the power assembly can be amplified to open the first body and the second body. Moreover, since the power assembly is used to push a lever disposed on the second body on the first body, the power assembly is also convenient for pushing the second body to continue moving. Thus, the opening angle between the first body and the second body can be increased in the second stage.

[0008] In addition, the housing according to the above technical solution provided by the present invention may further have the following additional technical features:

[0009] Based on the above technical solution, further, the second body includes: a second body portion; a groove disposed on the side of the second body portion facing the first body, and at least a part of the gear, at least a part of the first rack, and at least a part of the second rack are disposed in the groove.

[0010] In this technical solution, the second body includes a second body portion and a groove disposed on the second body portion. The opening of the groove faces the first body, and at least a part of the gear, at least a part of the first rack, and at least a part of the second rack are located inside the groove. Thus, the installation space of the gear, the first rack, and the second rack is saved, and the possibility of damage to the gear, the first rack, and the second rack due to external force collision is reduced.

[0011] Based on any of the above technical solutions, further, the second body includes: a second body portion, the gear, the first rack, and the second rack are disposed on the circumferential side of the second body; a second boss disposed on the circumferential side of the second body, and the second boss and the second rack are correspondingly disposed.

[0012] In this technical solution, the second body includes a second body portion and a second boss. The second boss is disposed on the circumferential side of the second body portion, and the second rack is correspondingly disposed with the second boss. Thus, when the second rack is driven by the power assembly to run to a certain position, the second rack abuts against the second boss, thereby pushing the second body to rotate, and thus increasing the opening angle between the first body and the second body.

[0013] Based on any of the above technical solutions, further, the second body further includes: a first guiding portion provided on the second body portion, and a first rack provided on the first guiding portion; and / or the second body further includes: a second guiding portion provided on the second body portion, and a second rack provided on the second guiding portion.

[0014] In this technical solution, the second body further includes a first guiding portion. The first guiding portion is disposed in the groove, and the first rack is matched with the first guiding portion. Thus, the first rack can move along the first guiding portion, making the movement of the first rack smoother. The second body further includes a second guiding portion. The second guiding portion is disposed in the groove, and the second rack is matched with the second guiding portion. Thus, the second rack can move along the second guiding portion, making the movement of the second rack smoother.

[0015] Based on any of the above technical solutions, further, the groove includes a limiting bottom wall corresponding to the second rack. After the power assembly makes the second rack contact the limiting bottom wall, the power assembly can continue to drive the second rack to move in the direction of the second body.

[0016] In this technical solution, the groove includes a limiting bottom wall which is arranged corresponding to the second rack. After the power assembly drives the second rack to move until it abuts against the limiting bottom wall, the power assembly can continue to drive the second rack to move, so as to continue to push the first body and the second body to open further, thereby increasing the opening angle of the first body and the second body, and further enhancing the effect of assisting in opening the door.

[0017] Based on any of the above technical solutions, further, the gear is a double gear, and the gear includes: a first gear meshing with the first rack; a second gear arranged in parallel with the first gear, and the second gear meshing with the second rack. The diameter of the pitch circle of the second gear is larger than the diameter of the pitch circle of the first gear.

[0018] In this technical solution, the gear adopts a double gear. Specifically, the gear includes a first gear and a second gear arranged side by side. The first gear meshes with the first rack, and the second gear meshes with the second rack. Moreover, the diameter of the pitch circle of the second gear is larger than the diameter of the pitch circle of the first gear. Thus, through the transmission of the gear, the output force of the power assembly can be amplified, further enhancing the opening force on the first body and the second body. Therefore, when the power of the power assembly is small, the force received by the second body can be further increased. Furthermore, the gear, the first rack, and the second rack can be closer to the rotation center of the first body and the second body, which is beneficial to further increasing the opening angle of the first body and the second body and enhancing the effect of assisting in opening the door.

[0019] Based on any of the above technical solutions, further, the first gear is a full-tooth gear or a half-tooth gear; the second gear is a full-tooth gear or a half-tooth gear.

[0020] In this technical solution, the first gear can be a full-tooth gear or a half-tooth gear, and the second gear can be a full-tooth gear or a half-tooth gear.

[0021] On the basis of any of the above technical solutions, further, the gear includes: a first main body, the circumferential side of the first main body includes a first side and a third tooth portion, and the third tooth portion meshes with the first rack; a second main body, the circumferential side of the second main body includes a second side and a fourth tooth portion, and the fourth tooth portion meshes with the second rack. The first side and the second side are connected, the pitch circles of the third tooth portion and the fourth tooth portion are coaxial, and the diameter of the pitch circle of the fourth tooth portion is greater than the diameter of the pitch circle of the third tooth portion.

[0022] In this technical solution, the gear includes a first main body and a second main body. The circumferential side of the first main body includes a first side and a third tooth portion, and the circumferential side of the second main body includes a second side and a fourth tooth portion. The first main body and the second main body are butted through the first side and the second side. The third tooth portion faces away from the second main body, and the fourth tooth portion faces away from the first main body. That is, a gear is composed of two half-tooth gears. The third tooth portion meshes with the first rack, and the fourth tooth portion meshes with the second rack. Moreover, the diameter of the pitch circle of the fourth tooth portion is greater than the diameter of the pitch circle of the third tooth portion. Furthermore, through the conduction of the gear, the output force of the power assembly can be amplified, and the opening force on the first body and the second body can be further increased. Thus, when the power of the power assembly is small, the force on the second body can be further increased. Furthermore, the gear, the first rack, and the second rack can be closer to the rotation center of the first body and the second body, which is beneficial to further increasing the opening angle of the first body and the second body and improving the effect of assisting in opening the door.

[0023] On the basis of any of the above technical solutions, further, the power assembly includes: a power member; a movable member disposed on the power member, and the power member is used to drive the movable member to move.

[0024] In this technical solution, the power assembly includes a power member and a movable member. The movable member is arranged on the power member. The power member can drive the movable member to move, and the movable member can drive the second rack to move, thereby realizing assisting in opening the door.

[0025] On the basis of any of the above technical solutions, further, the movable member is rotatably connected to the second rack.

[0026] In this technical solution, since the position of the gear changes in an arc when the first body and the second body are opened, therefore, the rotational connection between the movable member and the second rack can continue to drive the second rack to move after the first body and the second body are opened by a certain angle, thereby making the operation of the movable member smoother and reducing the possibility of the movable member being stuck.

[0027] On the basis of any of the above technical solutions, further, the power component includes any one of the following: electromagnetic power component, electric power component, pneumatic power component, and hydraulic power component.

[0028] In this technical solution, the power component includes any one of an electromagnetic power component, an electric power component, a pneumatic power component, and a hydraulic power component.

[0029] On the basis of any of the above technical solutions, further, it further includes: a first rotating shaft, and the first body and the second body are connected by the first rotating shaft.

[0030] In this technical solution, the housing further includes a first rotating shaft, and the first body and the second body are pivotally connected by the first rotating shaft.

[0031] On the basis of any of the above technical solutions, further, it further includes: a second rotating shaft, and the gear is installed on the second body through the second rotating shaft.

[0032] In this technical solution, the housing further includes a second rotating shaft, and the gear and the second body are rotatably connected by the second rotating shaft.

[0033] On the basis of any of the above technical solutions, further, the first body is a box body, and the second body is a door body.

[0034] In this technical solution, the first body is a box body, and the second body is a door body.

[0035] On the basis of any of the above technical solutions, further, relative to the first rack, the second rack is away from the first rotating shaft; or relative to the first rack, the second rack is close to the first rotating shaft.

[0036] In this technical solution, the second rack is away from the first rotating shaft relative to the first rack. Since the first body and the second body are rotatably connected, therefore, the opening size at the position close to the first rotating shaft of the first body and the second body is smaller than that at the position away from the first rotating shaft. Therefore, the second rack is away from the first rotating shaft. In the first stage, as long as the first rack runs a short stroke, it can pry open the first body and the second body, and thus the length of the first rack can be reduced, saving materials and reducing costs. In the second stage, the force arm is increased, and a smaller force can be used to increase the angle between the first body and the second body.

[0037] The second rack is close to the first rotating shaft relative to the first rack. Since the first body and the second body are rotatably connected, and then the second rack is close to the first rotating shaft. In the first stage, the force arm is increased, and thus the power component can use a smaller force to open the first body and the second body, thereby reducing costs. In the second stage, the second rack can open the first body and the second body at a larger angle with a smaller stroke.

[0038] According to a second aspect of the present invention, the present invention provides a storage device, comprising: a housing as described in any one of the above technical solutions.

[0039] Since the storage device provided by the present invention includes a housing as described in any one of the above technical solutions, it thus has all the beneficial effects of the housing as described in any one of the above technical solutions, which will not be elaborated one by one herein.

Detailed implementation manners

[0064] To more clearly understand the above objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0065] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0066] The following refers to Figure 1 and Figure 20 to describe the housing 100 and the storage device provided according to some embodiments of the present invention.

[0067] Embodiment 1:

[0068] As Figures 1 to 15 shown, the present invention provides a housing 100 including: a first body 110, a second body 120, a first rack 160, a gear 140, a second rack 170, and a power assembly 180. Among them, the gear 140 is disposed on the second body 120, the power assembly 180 is disposed on the first body 110, both the first rack 160 and the second rack 170 are engaged with the gear 140, and the first tooth portion 162 of the first rack 160 and the second tooth portion 172 of the second rack 170 are disposed opposite to each other. Thus, when the gear 140 rotates, the moving directions of the first rack 160 and the second rack 170 are opposite. One end of the first rack 160 faces the first body 110, and the power assembly 180 cooperates with the second rack 170. Thus, the power assembly 180 can drive the second rack 170 to move, the second rack 170 drives the gear 140 to rotate, the gear 140 drives the first rack 160 to move, and the first rack 160 moves in the direction of the first body 110, thereby pushing open the first body 110 and the second body 120.

[0069] The housing 100 provided by the present invention includes a first body 110, a second body 120, a first rack 160, a gear 140, a second rack 170, and a power assembly 180. The power assembly 180 is disposed on the first body 110, the gear 140 is disposed on the second body 120, a first gear 142 and a second gear 144 are respectively disposed on both sides of the gear 140 and are engaged with the gear 140. When the second rack 170 moves away from the first body 110, the gear 140 rotates and drives the first rack 160 to move towards the first body 110. Thus, the gear 140 receives a force exerted by the second rack 170, and the first rack 160 abuts against the first body 110, such that the gear 140 receives a force exerted by the first rack 160. Therefore, the gear 140 receives two forces, and the second body 120 receives two forces. Among them, the force exerted by the second rack 170 on the gear 140 is equal to the output of the power assembly 180. Therefore, the force received by the second body 120 is greater than the output force of the power assembly 180. Thus, in the first stage, the output force of the power assembly 180 can be amplified to open the first body 110 and the second body 120. And because the power assembly 180 is pushing a lever disposed on the second body 120 on the first body 110, the power assembly 180 is also convenient for pushing the second body 120 to move continuously. Thus, in the second stage, the opening angle of the first body 110 and the second body 120 can be increased.

[0070] Moreover, the gear 140, the first rack 160, and the second rack 170 can be close to the rotation center of the first body 110 and the second body 120, which is beneficial to increasing the opening angle of the first body 110 and the second body 120 and enhancing the effect of assisting in opening the door.

[0071] Furthermore, when the first body 110 and the second body 120 are closed, the first rack 160 abuts against the first body 110.

[0072] Embodiment 2:

[0073] As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 20 On the basis of Embodiment 1, further, the second body 120 includes a second body portion 122 and a groove 124 disposed on one side of the second body portion 122. A part of the gear 140, a part of the first rack 160, and a part of the second rack 170 are disposed in the groove 124. Specifically, the groove 124 is disposed on the side of the second body portion 122 facing the first body 110.

[0074] In this technical solution, the second body 120 includes a second body portion 122 and a groove 124 provided on the second body portion 122. The opening of the groove 124 faces the first body 110. A part of the gear 140, a part of the first rack 160, and a part of the second rack 170 are located inside the groove 124, thereby saving the installation space of the gear 140, the first rack 160, and the second rack 170, and reducing the possibility of damage to the gear 140, the first rack 160, and the second rack 170 due to external force collision.

[0075] Embodiment 3:

[0076] On the basis of Embodiment 1, further, the second body 120 includes a second body portion 122 and a groove 124 provided on one side of the second body portion 122. The gear 140, the first rack 160, and the second rack 170 are provided in the groove 124. Specifically, the groove 124 is provided on the side of the second body portion 122 facing the first body 110.

[0077] In this technical solution, the second body 120 includes a second body portion 122 and a groove 124 provided on the second body portion 122. The opening of the groove 124 faces the first body 110. The gear 140, the first rack 160, and the second rack 170 are located inside the groove 124, thereby saving the installation space of the gear 140, the first rack 160, and the second rack 170, and reducing the possibility of damage to the gear 140, the first rack 160, and the second rack 170 due to external force collision.

[0078] Embodiment 4:

[0079] As Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 20 shown, on the basis of Embodiment 2 or Embodiment 3, further, the second body 120 further includes a first guiding portion 126 provided on the second body portion 122. The first guiding portion 126 is provided in the groove 124, so that the first rack 160 can move along the first guiding portion 126.

[0080] In this embodiment, the second body 120 further includes a first guiding portion 126. The first guiding portion 126 is provided in the groove 124. The first rack 160 and the first guiding portion 126 are matched, so that the first rack 160 can move along the first guiding portion 126, thereby making the movement of the first rack 160 smoother.

[0081] Specifically, the first guiding portion 126 can be a first guiding groove or a first guiding protrusion. A first engaging groove or a first protrusion matching the first guiding portion 126 is provided on the first rack 160.

[0082] Example 5:

[0083] As Figure 1 , Figure 4 and Figure 20 shown, on the basis of any one of Embodiments 2 to 4, further, the second body 120 further includes a second guiding portion 128 disposed on the second body portion 122. The second guiding portion 128 is disposed in the groove 124, and thus the second rack 170 can move along the second guiding portion 128. Specifically, the first guiding portion 126 and the second guiding portion 128 are arranged side by side.

[0084] In this embodiment, the second body 120 further includes a second guiding portion 128. The second guiding portion 128 is disposed in the groove 124, and the second rack 170 is matched with the second guiding portion 128. Thus, the second rack 170 can move along the second guiding portion 128, making the movement of the second rack 170 smoother.

[0085] Specifically, the second guiding portion 128 can be a second guiding groove or a second guiding protrusion, and the second rack 170 is provided with a second engaging groove or a second protrusion that is matched with the second guiding portion 128.

[0086] Example 6:

[0087] As Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 shown, on the basis of Embodiment 1, further, the second body 120 includes: a second body portion 122 and a second boss 132. The second boss 132 is disposed on the circumferential side of the second body 120. The gear 140, the first rack 160, and the second rack 170 are disposed on the circumferential side of the second body 120, and the second boss 132 and the second rack 170 are correspondingly arranged.

[0088] In this embodiment, the second body 120 includes a second body portion 122 and a second boss 132. The second boss 132 is disposed on the circumferential side of the second body portion 122, and the second rack 170 is correspondingly arranged with respect to the second boss 132. Thus, when the second rack 170 is driven by the power assembly 180 to run to a certain position, the second rack 170 abuts against the second boss 132, thereby pushing the second body 120 to rotate, and further increasing the opening angle between the first body 110 and the second body 120.

[0089] Specifically, a first boss 112 is provided on the first body 110. The first boss 112 corresponds to the first rack 160. In the first stage, the power assembly 180 drives the second rack 170 to move. The first rack 160 abuts against the first boss 112, causing the first body 110 and the second body 120 to open. Moreover, in the second stage, the second rack 170 abuts against the second boss 132, and the power assembly 180 continuously outputs power, causing the second rack 170 to push the second boss 132. Further, the second body 120 continues to open, increasing the opening angle of the first body 110 and the second body 120.

[0090] Specifically, under normal circumstances, a door closer is installed at the lower end of the housing 100. When the opening angle of the second body 120 is relatively small, generally less than 8°, which is specifically related to the structure of the door closer, the second body 120 will automatically close under the action of the door closer, thereby ensuring that even if the user fails to fully close the housing 100, the housing 100 can still automatically close the door.

[0091] Moreover, when the first body 110 and the second body 120 are opened, there is a characteristic. Generally, when the opening angle of the first body 110 and the second body 120 < 2°, the opening force is relatively large. Because at this time, the negative pressure inside the housing 100 and the suction force between the door sealing magnetic strip and the first body 110 and the second body 120 are relatively large. Once the opening angle of the first body 110 and the second body 120 exceeds about 2°, the negative pressure and magnetic suction force disappear, and the opening force drops sharply.

[0092] The housing 100 provided by the present invention combines the advantages of opening the door with the first rack 160, the second rack 170, and the gear 140. In the first stage, the output force of the power assembly 180 is amplified, and in the second stage, the stroke of the second body 120 is enlarged. That is, only the thrust is amplified in the first stage, and the stroke is not reduced in the subsequent stroke. Thus, it is ensured that the second body 120 can be opened to a relatively large angle, which can be greater than the limited angle of the door closer, realizing normal automatic door opening.

[0093] Embodiment 7:

[0094] As Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 shown, on the basis of Embodiment 6, further, the second body 120 further includes a first guiding portion 126 provided on the second body portion 122. The first guiding portion 126 is provided inside the circumferential side of the second body 120. Further, the first rack 160 can move along the first guiding portion 126.

[0095] In this embodiment, the second body 120 also includes a first guide portion 126, which is arranged on the peripheral side of the second body 120, and the first rack 160 matches the first guide portion 126, so that the first rack 160 can move along the first guide portion 126, thereby making the movement of the first rack 160 smoother.

[0096] Specifically, the first guide portion 126 may be a first guide groove or a first guide protrusion, and the first rack 160 is provided with a first slot or a first protrusion matching the first guide portion 126 .

[0097] Embodiment 8:

[0098] like Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, on the basis of Embodiment 6 or Embodiment 7, further, the second body 120 further includes a second guide portion 128 disposed on the second body portion 122, and the second guide portion 128 is disposed on the circumference of the second body 120, so that the second rack 170 can move along the second guide portion 128. Specifically, the first guide portion and the second guide portion are disposed side by side.

[0099] In this embodiment, the second body 120 also includes a second guide portion 128, which is arranged on the circumferential side of the second body 120, and the second rack 170 matches the second guide portion 128, so that the second rack 170 can move along the second guide portion 128, thereby making the movement of the second rack 170 smoother.

[0100] Specifically, the second guide portion 128 may be a second guide groove or a second guide protrusion, and the second rack 170 is provided with a second slot or a second protrusion matching the second guide portion 128 .

[0101] Embodiment 9:

[0102] like Figure 20 As shown, on the basis of any one of Examples 1 to 8, further, the groove 124 includes a limiting bottom wall 130, and the limiting bottom wall 130 is arranged corresponding to the second rack 170. After the power component 180 drives the second rack 170 to move so that the first rack 160 pushes open the first body 110 and the second body 120, the second rack 170 and the limiting bottom wall 130 are abutted against each other, and then the power component 180 continues to drive the second rack 170 to move, so that the second body 120 can continue to rotate, thereby increasing the opening angle of the first body 110 and the second body 120.

[0103] In this embodiment, the groove 124 includes a limiting bottom wall 130 which is arranged corresponding to the second rack 170. After the power assembly 180 drives the second rack 170 to move until it abuts against the limiting bottom wall 130, the power assembly 180 can continue to drive the second rack 170 to move, so as to continue to push the first body 110 and the second body 120 to open further, thereby increasing the opening angle of the first body 110 and the second body 120, and further enhancing the effect of assisting in opening the door.

[0104] Specifically, the limiting bottom wall 130 is a plane, and one end of the second rack 170 facing the limiting bottom wall 130 is a plane. The plane of the limiting bottom wall 130 is in contact, which can better transmit power.

[0105] That is to say, the opening process of the first body 110 and the second body 120 mainly includes two stages, as Figure 1 and Figure 4 shown. Initially, the first body 110 and the second body 120 are closed. As Figure 2 and Figure 5 shown, in the first stage, the power assembly 180 drives the second rack 170 to move, the second rack 170 drives the gear 140 to rotate, and the gear 140 drives the first rack 160 to move, so that the first rack 160 pushes open the first body 110 and the second body 120. Furthermore, the first body 110 exerts a force on the gear 140, and the power assembly 180 exerts a force on the gear 140 through the second rack 170, thereby amplifying the output force of the power assembly 180, so as to overcome the suction force of the door seal magnetic strip, the negative pressure inside the door, the force brought by the self-locking mechanism, the static friction at positions such as the door rotating shaft, etc., so that the first rack 160 pushes open the first body 110 and the second body 120. As Figure 3 and Figure 6 shown, in the second stage, after the second rack 170 and the limiting bottom wall 130 are in contact, the second rack 170 cannot continue to drive the gear 140 to rotate, while the power assembly 180 continues to drive the second rack 170 to move. Then the second rack 170 pushes the second body 120 to continue to rotate, thereby increasing the opening angle of the first body 110 and the second body 120, so as to overcome the force brought by the self-locking mechanism and the dynamic friction at positions such as the door rotating shaft. Furthermore, in the first stage, the first body 110 and the second body 120 can be opened by using a low-power power assembly 180, and in the second stage, there will be no problem of excessive output of the power assembly 180.

[0106] Specifically, a door closer is usually installed at the lower end of the housing 100. When the second body 120 is opened at a small angle, generally less than 8°, the second body 120 will automatically close under the action of the door closer, which is related to the structure of the door closer, thereby ensuring that the housing 100 can be automatically closed even if the user fails to completely close the housing 100.

[0107] In addition, when the first body 110 and the second body 120 are opened, there is a characteristic that generally when the opening angle of the first body 110 and the second body 120 is less than 2°, the door opening force is relatively large. This is because at this time, the negative pressure inside the housing 100 and the suction force between the door seal magnetic strip and the first body 110 and the second body 120 are relatively large. Once the opening angle of the first body 110 and the second body 120 exceeds about 2°, the negative pressure and magnetic suction force disappear, and the door opening force drops sharply.

[0108] The housing 100 provided by the present invention combines the advantages of the first rack 160, the second rack 170 and the gear 140 for opening the door, amplifies the output force of the power assembly 180 in the first stage, and expands the stroke of the second body 120 in the second stage. That is, the thrust is only amplified in the first stage, and the stroke is no longer reduced thereafter. This ensures that the second body 120 can be opened to a larger angle, which can be greater than the limited angle of the door closer, and realizes normal automatic door opening.

[0109] Embodiment 10:

[0110] like Figure 16 , Figure 17 and Figure 18 As shown, on the basis of any one of Examples 1 to 9, further, the gear 140 adopts a double gear 140, that is, the gear 140 is two side-by-side gears 140, specifically, the gear 140 includes a first gear 142 and a second gear 144, the first gear 142 is located on one side of the second gear 144, the first gear 142 and the second gear 144 are coaxial and rotate synchronously, wherein the first gear 142 and the first rack 160 are engaged with each other, the second gear 144 and the second rack 170 are meshed with each other, and the diameter of the pitch circle of the second gear 144 is greater than the diameter of the pitch circle of the first gear 142.

[0111] In this embodiment, the gear 140 is a compound gear 140. Specifically, the gear 140 includes a first gear 142 and a second gear 144 arranged side by side. The first gear 142 meshes with the first rack 160, and the second gear 144 meshes with the second rack 170. Moreover, the diameter of the pitch circle of the second gear 144 is greater than that of the pitch circle of the first gear 142. Then, through the transmission of the gear 140, according to the conservation of work, the radius of the pitch circle of the first gear 142 × the opening force of the first rack 160 on the first body 110 and the second body 120 = the radius of the pitch circle of the second gear 144 × the output force of the power assembly 180 on the second rack 170. Since the radius of the pitch circle of the first gear 142 is smaller than that of the pitch circle of the second gear 144, the opening force of the first rack 160 on the first body 110 and the second body 120 is greater than the output force of the power assembly 180 on the second rack 170. Thus, the output force of the power assembly 180 is amplified, and the opening force on the first body 110 and the second body 120 is further increased. Therefore, when the power of the power assembly 180 is relatively small, the force on the second body 120 can be further increased. Furthermore, the gear 140, the first rack 160, and the second rack 170 can be closer to the rotation center of the first body 110 and the second body 120, which is beneficial to further increasing the opening angle of the first body 110 and the second body 120 and enhancing the effect of assisting in opening the door.

[0112] Moreover, the diameter of the pitch circle of the second gear 144 is greater than that of the pitch circle of the first gear 142, so the stroke of the second rack 170 will be greater than that of the first rack 160. Thus, the opening angle of the first body 110 and the second body 120 can be increased. At the same time, the stroke of the first rack 160 can be reduced, and the volume of the second body 120 can be decreased.

[0113] Embodiment 11:

[0114] On the basis of Embodiment 10, further, the first gear 142 is a full-tooth gear, and the second gear 144 is a full-tooth gear. Or the first gear 142 is a half-tooth gear, and the second gear 144 is a full-tooth gear. Or the first gear 142 is a full-tooth gear, and the second gear 144 is a half-tooth gear. Or the first gear 142 is a half-tooth gear, and the second gear 144 is a half-tooth gear.

[0115] In this embodiment, the first gear 142 can be a full-tooth gear or a half-tooth gear, and the second gear 144 can be a full-tooth gear or a half-tooth gear.

[0116] Embodiment 12:

[0117] Such as Figure 19As shown, on the basis of any one of Embodiments 1 to 9, further, the gear 140 includes a first main body 146 and a second main body 148. That is to say, the gear 140 is formed by splicing the first main body 146 and the second main body 148. The first main body 146 has a semi-circular structure, and the second main body 148 has a semi-circular structure. Specifically, the circumferential side of the first main body 146 includes a first side and a third tooth part 150, and the circumferential side of the second main body 148 includes a second side and a fourth tooth part 152. The first side and the second side are spliced oppositely. Further, the third tooth part 150 faces away from the second main body 148, the fourth tooth part 152 faces away from the first main body 146, and the diameter of the pitch circle of the fourth tooth part 152 is greater than the diameter of the pitch circle of the third tooth part 150.

[0118] In this embodiment, the gear 140 includes a first main body 146 and a second main body 148. The circumferential side of the first main body 146 includes a first side and a third tooth part 150, and the circumferential side of the second main body 148 includes a second side and a fourth tooth part 152. The first main body 146 and the second main body 148 are butted through the first side and the second side. The third tooth part 150 faces away from the second main body 148, and the fourth tooth part 152 faces away from the first main body 146. That is, a gear 140 is composed of two semi-tooth gears 140. The third tooth part 150 meshes with the first rack 160, and the fourth tooth part 152 meshes with the second rack 170. Moreover, the diameter of the pitch circle of the fourth tooth part 152 is greater than the diameter of the pitch circle of the third tooth part 150. Further, through the transmission of the gear 140, the output force of the power assembly 180 can be amplified, and the opening force on the first body 110 and the second body 120 can be further improved. Thus, when the power of the power assembly 180 is small, the force received by the second body 120 can be further increased. Furthermore, the gear 140, the first rack 160, and the second rack 170 can be closer to the rotation center of the first body 110 and the second body 120, which is beneficial to further increasing the opening angle of the first body 110 and the second body 120 and improving the effect of assisting in opening the door.

[0119] Specifically, the gear 140 adopts a form of being spliced by two segments. Since the volume of the second body 120 is limited and the stroke of the second rack 170 is small, therefore, the gear 140 does not need to rotate a complete circle, and it can rotate half a circle, one-third of a circle, one-fourth of a circle, etc.

[0120] Embodiment 13:

[0121] As Figures 1 to 15 shown, on the basis of any one of Embodiments 1 to 12, further, the power assembly 180 includes a power member 182 and a movable member 184. The movable member 184 is arranged on the power member 182, and the power member 182 is used to drive the movable member 184 to move.

[0122] In this embodiment, the power assembly 180 includes a power member 182 and a movable member 184. The movable member 184 is disposed on the power member 182. The power member 182 can drive the movable member 184 to move, and the movable member 184 can drive the second rack 170 to move, thereby achieving assisted door opening.

[0123] Specifically, one end of the movable member 184 is connected to the second rack 170.

[0124] Embodiment 14:

[0125] As Figures 1 to 15 shown, on the basis of Embodiment 13, further, the movable member 184 and the second rack 170 are rotatably connected.

[0126] In this embodiment, when the first body 110 and the second body 120 are opened, the position of the gear 140 changes in an arc shape. Therefore, the rotatable connection between the movable member 184 and the second rack 170 can continue to drive the second rack 170 to move after the first body 110 and the second body 120 are opened by a certain angle, thereby making the operation of the movable member 184 smoother, reducing the possibility of the movable member 184 being stuck, and reducing the requirement for torque during the door opening process.

[0127] Specifically, one end of the movable member 184 is rotatably connected to the second rack 170.

[0128] Embodiment 15:

[0129] On the basis of Embodiment 14, further, the power member 182 includes any one of the following: an electromagnetic power member 182, a motor power member 182, a pneumatic power member 182, and a hydraulic power member 182.

[0130] In this embodiment, the power member 182 includes any one of an electromagnetic power member 182, a motor power member 182, a pneumatic power member 182, and a hydraulic power member 182.

[0131] Specifically, the electromagnetic power member 182 can use magnetic force to push the movable member 184 to move. For example, the movable member 184 is driven to move by an electromagnet.

[0132] The motor power member 182 can use a motor to drive the movable member 184 to move. For example, the movable member 184 is driven to move by a motor.

[0133] The pneumatic power member 182 can use gas to drive the movable member 184 to move. For example, the movable member 184 is driven to move by a cylinder.

[0134] The hydraulic power member 182 can use liquid to drive the movable member 184 to move. For example, the movable member 184 is driven to move by a hydraulic cylinder.

[0135] Specifically, as Figures 1 to 3 and Figures 7 to 15 shown, in the first stage, the electromagnetic power component 182 drives the second rack 170 to move. The second rack 170 drives the gear 140 to rotate, and the gear 140 drives the first rack 160 to move, so that the first rack 160 pushes open the first body 110 and the second body 120. Furthermore, the first body 110 exerts a force on the gear 140, and the electromagnetic power component 182 exerts a force on the gear 140 through the second rack 170, thereby amplifying the output force of the electromagnetic power component 182, achieving the overcoming of the suction force of the door seal magnetic strip, the negative pressure inside the door, the force brought by the self-locking mechanism, the static friction force at positions such as the door rotating shaft, etc. between the first body 110 and the second body 120, so that the first rack 160 pushes open the first body 110 and the second body 120. In the second stage, after the second rack 170 and the limiting bottom wall 130 are in contact, the second rack 170 cannot continue to drive the gear 140 to rotate, while the electromagnetic power component 182 continues to drive the second rack 170 to move. Furthermore, the second rack 170 pushes the second body 120 to continue rotating, thereby expanding the opening angle between the first body 110 and the second body 120, thus overcoming the force brought by the self-locking mechanism and the dynamic friction force at positions such as the door rotating shaft. Furthermore, in the first stage, it is possible to use a low-power electromagnetic power component 182 to open the first body 110 and the second body 120, and in the second stage, there will be no problem of excessive output of the electromagnetic power component 182.

[0136] As Figures 4 to 6 shown, in the first stage, the motor power component 182 drives the second rack 170 to move. The second rack 170 drives the gear 140 to rotate, and the gear 140 drives the first rack 160 to move, so that the first rack 160 pushes open the first body 110 and the second body 120. Furthermore, the first body 110 exerts a force on the gear 140, and the motor power component 182 exerts a force on the gear 140 through the second rack 170, thereby amplifying the output force of the motor power component 182, achieving the overcoming of the suction force of the door seal magnetic strip, the negative pressure inside the door, the force brought by the self-locking mechanism, the static friction force at positions such as the door rotating shaft, etc. between the first body 110 and the second body 120, so that the first rack 160 pushes open the first body 110 and the second body 120. In the second stage, after the second rack 170 and the limiting bottom wall 130 are in contact, the second rack 170 cannot continue to drive the gear 140 to rotate, while the motor power component 182 continues to drive the second rack 170 to move. Furthermore, the second rack 170 pushes the second body 120 to continue rotating, thereby expanding the opening angle between the first body 110 and the second body 120, thus overcoming the force brought by the self-locking mechanism and the dynamic friction force at positions such as the door rotating shaft. Furthermore, in the first stage, it is possible to use a low-power motor power component 182 to open the first body 110 and the second body 120, and in the second stage, there will be no problem of excessive output of the motor power component 182.

[0137] In the first stage, the pneumatic power component 182 drives the second rack 170 to move. The second rack 170 drives the gear 140 to rotate, and the gear 140 drives the first rack 160 to move, so that the first rack 160 pushes open the first body 110 and the second body 120. Furthermore, the first body 110 exerts a force on the gear 140, and the pneumatic power component 182 exerts a force on the gear 140 through the second rack 170, thereby amplifying the output force of the pneumatic power component 182, achieving the overcoming of the suction force of the door seal magnetic strip, the negative pressure inside the door, the force brought by the self-locking mechanism, the static friction force at positions such as the door rotating shaft, etc. between the first body 110 and the second body 120, so that the first rack 160 pushes open the first body 110 and the second body 120. In the second stage, after the second rack 170 and the limiting bottom wall 130 are in contact, the second rack 170 cannot continue to drive the gear 140 to rotate, while the pneumatic power component 182 continues to drive the second rack 170 to move. Furthermore, the second rack 170 pushes the second body 120 to continue rotating, thereby expanding the opening angle between the first body 110 and the second body 120, thus overcoming the force brought by the self-locking mechanism and the dynamic friction force at positions such as the door rotating shaft. Furthermore, in the first stage, it is possible to use a low-power pneumatic power component 182 to open the first body 110 and the second body 120, and in the second stage, there will be no problem of excessive output of the pneumatic power component 182.

[0138] In the first stage, the hydraulic power component 182 drives the second rack 170 to move. The second rack 170 drives the gear 140 to rotate, and the gear 140 drives the first rack 160 to move, so that the first rack 160 pushes open the first body 110 and the second body 120. Furthermore, the first body 110 exerts a force on the gear 140, and the hydraulic power component 182 exerts a force on the gear 140 through the second rack 170, thereby amplifying the output force of the hydraulic power component 182, achieving the overcoming of the suction force of the door seal magnetic strip, the negative pressure inside the door, the force brought by the self-locking mechanism, the static friction force at positions such as the door rotating shaft, etc. between the first body 110 and the second body 120, so that the first rack 160 pushes open the first body 110 and the second body 120. In the second stage, after the second rack 170 and the limiting bottom wall 130 are in contact, the second rack 170 cannot continue to drive the gear 140 to rotate, while the hydraulic power component 182 continues to drive the second rack 170 to move. Furthermore, the second rack 170 pushes the second body 120 to continue rotating, thereby expanding the opening angle between the first body 110 and the second body 120, thus overcoming the force brought by the self-locking mechanism and the dynamic friction force at positions such as the door rotating shaft. Furthermore, in the first stage, it is possible to use a low-power hydraulic power component 182 to open the first body 110 and the second body 120, and in the second stage, there will be no problem of excessive output of the hydraulic power component 182.

[0139] Embodiment 16:

[0140] As Figures 1 to 15 shown, based on any one of Embodiments 1 to 15, further, the housing 100 further includes a first rotating shaft 190, both the first body 110 and the second body 120 are connected to the first rotating shaft 190, and at least one of the first body 110 and the second body 120 can rotate relative to the first rotating shaft 190.

[0141] In this embodiment, the housing 100 further includes a first rotating shaft 190, and the first body 110 and the second body 120 are pivotally connected through the first rotating shaft 190.

[0142] Specifically, the first rotating shaft 190 can be integrally designed with the first body 110, the second body 120 is installed on the first rotating shaft 190, or integrally designed with the second body 120, the first body 110 is installed on the first device, or the first body 110, the second body 120, and the first rotating shaft 190 are all separately designed.

[0143] Embodiment 17:

[0144] As Figures 1 to 15 shown, based on any one of Embodiments 1 to 16, further, the housing 100 further includes a second rotating shaft 200, and the gear 140 and the second body 120 are connected through the second rotating shaft 200. Specifically, the second rotating shaft 200 is disposed in the groove 124 of the second body 120.

[0145] In this embodiment, the housing 100 further includes a second rotating shaft 200, and the gear 140 and the second body 120 are rotatably connected through the second rotating shaft 200.

[0146] Embodiment 18:

[0147] Based on any one of Embodiments 1 to 17, further, the first body 110 is a box body, and the second body 120 is a door body.

[0148] In this embodiment, the first body 110 is a box body, and the second body 120 is a door body.

[0149] Embodiment 19:

[0150] Based on any one of Embodiments 1 to 18, further, the number of the second bodies 120 is one or more.

[0151] Specifically, one or more second bodies 120 can be installed on a first body 110. When the number of second bodies 120 is multiple, one second body 120 is matched with a set of first racks 160, gears 140, and second racks 170. Multiple sets of first racks 160, gears 140, and second racks 170 can share the same power assembly 180 or each set of first racks 160, gears 140, and second racks 170 is matched with a power assembly 180.

[0152] Embodiment 20:

[0153] As Figure 1 shown, the housing 100 provided by the present invention includes a first body 110, a second body 120, a gear 140, a first rack 160, a second rack 170, and a power assembly 180. Among them, the power assembly includes an electromagnetic power member, the gear 140 is a double gear 140, and the first rack 160 and the second rack 170 are respectively meshed with the first gear 142 and the second gear 144 of the double gear 140. The gear 140 is installed on the second body 120 through a second rotating shaft 200. A limiting bottom wall 130 is provided on the second body 120 to limit the maximum stroke of the second rack 170. A first guiding portion 126 and a second guiding portion 128 are provided on the second body 120. The first guiding portion 126 cooperates with the first rack 160, and the second guiding portion 128 cooperates with the second rack 170 to ensure the movement directions of the first rack 160 and the second rack 170. Specifically, the first rack 160 moves along a direction perpendicular to the second body 120, which is a linear motion, and the second rack 170 moves along a direction perpendicular to the second body 120, which is a linear motion.

[0154] As Figure 2 shown, when the power assembly 180 pushes the second rack 170 to move, the gear 140 will be driven to rotate by the second rack 170. The gear 140 drives the first rack 160 to move. The first rack 160 will contact the first body 110, and forces will be generated between them. Further, when the first rack 160 and the second body 120 are closed, the first rack 160 just contacts the first body 110. In this way, as long as the power assembly 180 pushes the second rack 170, the first rack 160 can immediately generate a force with the first body 110.

[0155] Among them, the opening force received at the second rotating shaft 200 = the force output by the power assembly 180 to the second rack 170 + the force generated between the first body 110 and the first rack 160. Therefore, the opening force received at the second rotating shaft 200 is greater than the force output by the power assembly 180 to the second rack 170.

[0156] This realizes the amplification of the door-opening force at the second rotating shaft 200 of the gear 140. Under normal circumstances, the electromagnetic power component 182 cannot push open the first body 110 and the second body 120 at the second rotating shaft 200. However, with the first rack 160, the gear 140, and the second rack 170, the electromagnetic power component 182 can push open the first body 110 and the second body 120 at the second rotating shaft 200.

[0157] This stage is the labor-saving stage of opening the door.

[0158] As Figure 3 shown, when the first body 110 and the second body 120 are pushed open by a certain angle, the required door-opening force is greatly reduced. At this time, the second rack 170 is pushed by the power assembly 180 to the limit bottom wall 130. The second rack 170 will remain stationary with the second body 120 and there will be no more force acting between it and the first body 110. The power assembly 180 will push the second rack 170 and the second body 120 forward together.

[0159] This stage is the non-labor-saving stage of opening the door.

[0160] According to the law of conservation of energy, in the labor-saving stage of opening the door, although the door-opening force is increased, the angular velocity of opening the door is sacrificed. In the non-labor-saving stage of opening the door, although the door-opening force is reduced, the angular velocity of opening the door is increased. This realizes the dynamic matching of the door-opening force provided by the power assembly 180 and the door-opening force required by the storage device at different door-opening angles. It can not only ensure that the door is pushed open but also ensure that the angle at which the door is pushed open is as large as possible.

[0161] As Figures 4 to 6 shown, a motor and a connecting rod can also be used to open the door. It only needs to hinge the connecting rod with the second rack 170. By doing so, the output torque requirement for opening the door with the connecting rod can be reduced. The entire connecting rod door-opening mechanism can select a motor power component 182 with a smaller power, the strength requirement of the structural parts can be reduced, and the thickness can be decreased.

[0162] The housing 100 provided by the present invention can realize the matching of the door-pushing force and the door-opening force required by the storage device. In the stage where a large door-opening force is required, it can provide a large door-pushing force. In the stage where a small door-opening force is required, it can provide a large door-opening angular velocity.

[0163] The requirement for the rated door-thrust can be reduced, thereby realizing the miniaturization and low cost of the mechanism.

[0164] The door-top position can be made closer to the door rotating shaft. The closer the door-top position is to the first rotating shaft 190, the smaller the door-top distance required to rotate the second body 120 by the same angle. This solves the problem that in some storage devices, the door cannot be pushed over the self-locking, resulting in the automatic closing of the door.

[0165] By adopting the electromagnetic power component 182, the pushing force of the door can be amplified, and the problem that the door cannot be pushed open can be solved.

[0166] Among them, as Figures 7 to 9 shown, the first gear 142 and the second gear 144 do not have to be full-tooth gears 140, and can be non-full-tooth gears 140.

[0167] Or, as Figure 10 shown, the gear 140 is in the form of being spliced by two main bodies, and this structure can be regarded as having the same function as the double-connected gear 140. Even the teeth on the gear 140 can be discontinuous, and can be regarded as two identical non-full-tooth gears 140 combined together.

[0168] Embodiment 21:

[0169] As Figures 1 to 6 shown, on the basis of any one of Embodiments 1 to 20, further, the second rack 170 is farther from the first rotating shaft 190 relative to the first rack 160.

[0170] In this embodiment, the second rack 170 is farther from the first rotating shaft 190 relative to the first rack 160. Since the first body 110 and the second body 120 are rotatably connected, the opening size at the position close to the first rotating shaft 190 of the first body 110 and the second body 120 is smaller than that at the position far from the first rotating shaft 190. Therefore, the second rack 170 is far from the first rotating shaft 190. In the first stage, as long as the first rack 160 runs a short stroke, the first body 110 and the second body 120 can be pried open, and then the length of the first rack 160 can be reduced, saving materials and reducing costs. In the second stage, the force arm is increased, and a smaller force can be used to increase the angle between the first body 110 and the second body 120.

[0171] Moreover, the second rack 170 is farther from the first rotating shaft 190 relative to the first rack 160. In the first stage, a smaller stroke can be used to make the first body 110 and the second body 120 open at a larger angle. The force arm in the second stage is larger, which is more convenient for the opening of the first body 110 and the second body 120, making it easier for the first body 110 and the second body 120 to be opened to a predetermined angle.

[0172] Specifically, the opening process of the first body 110 and the second body 120 mainly includes two stages. As Figure 1 and Figure 4 shown, initially the first body 110 and the second body 120 are closed. As Figure 2 and Figure 5As shown, in the first stage, the power assembly 180 drives the second rack 170 to move. The second rack 170 drives the gear 140 to rotate, and the gear 140 drives the first rack 160 to move, so that the first rack 160 pushes open the first body 110 and the second body 120. Furthermore, the first body 110 exerts a force on the gear 140, and the power assembly 180 exerts a force on the gear 140 through the second rack 170, thereby amplifying the output force of the power assembly 180 to overcome the suction force of the door seal magnetic strip between the first body 110 and the second body 120, the negative pressure inside the door, the force brought by the self-locking mechanism, the static friction at positions such as the door rotating shaft, etc., so that the first rack 160 pushes open the first body 110 and the second body 120. As Figure 3 and Figure 6 shown, in the second stage, after the second rack 170 and the limiting bottom wall 130 are attached, the second rack 170 cannot continue to drive the gear 140 to rotate, while the power assembly 180 continues to drive the second rack 170 to move. Furthermore, the second rack 170 pushes the second body 120 to continue rotating, thereby expanding the opening angle between the first body 110 and the second body 120, so as to overcome the force brought by the self-locking mechanism and the dynamic friction at positions such as the door rotating shaft. Furthermore, in the first stage, it is possible to use the low-power power assembly 180 to open the first body 110 and the second body 120, and there will be no problem of excessive output of the power assembly 180 in the second stage.

[0173] Embodiment 22:

[0174] As Figures 7 to 15 shown, on the basis of any one of Embodiments 1 to 20, further, the second rack 170 is closer to the first rotating shaft 190 relative to the first rack 160.

[0175] In this embodiment, the second rack 170 is closer to the first rotating shaft 190 relative to the first rack 160. Since the first body 110 and the second body 120 are rotatably connected, and then the second rack 170 is closer to the first rotating shaft 190, the force arm is increased in the first stage. Furthermore, the power assembly 180 can use a smaller force to open the first body 110 and the second body 120, thereby reducing costs. In the second stage, the second rack 170 can open the first body 110 and the second body 120 at a larger angle with a smaller stroke.

[0176] Moreover, the second rack 170 is closer to the first rotating shaft 190 relative to the first rack 160, and the force arm in the first stage is larger, which is more convenient for opening the first body 110 and the second body 120. In the second stage, the first body 110 and the second body 120 can be opened at a larger angle with a smaller stroke, which is more convenient for opening the first body 110 and the second body 120, making it easier for the first body 110 and the second body 120 to be...

[0177] Specifically, the opening process of the first body 110 and the second body 120 mainly includes two stages, as Figure 7 , Figure 8 and Figure 9 shown. Initially, the first body 110 and the second body 120 are closed. As Figure 10 , Figure 11 and Figure 12 shown, in the first stage, the power assembly 180 drives the second rack 170 to move. The second rack 170 drives the gear 140 to rotate, and the gear 140 drives the first rack 160 to move, so that the first rack 160 pushes open the first body 110 and the second body 120. Furthermore, the first body 110 exerts a force on the gear 140, and the power assembly 180 exerts a force on the gear 140 through the second rack 170, thereby amplifying the output force of the power assembly 180, achieving the suction force of the door seal strip between the first body 110 and the second body 120, the negative pressure inside the door, the force brought by the self-locking mechanism, the static friction force at positions such as the door rotating shaft, etc., so that the first rack 160 pushes open the first body 110 and the second body 120. As Figure 13 , Figure 14 and Figure 15 shown, in the second stage, after the second rack 170 and the limiting bottom wall 130 are attached, the second rack 170 cannot continue to drive the gear 140 to rotate, and the power assembly 180 continues to drive the second rack 170 to move. Then the second rack 170 pushes the second body 120 to continue rotating, thereby expanding the opening angle between the first body 110 and the second body 120, overcoming the force brought by the self-locking mechanism and the dynamic friction force at positions such as the door rotating shaft. Furthermore, in the first stage, the first body 110 and the second body 120 can be opened by using the low-power power assembly 180, and in the second stage, there will be no problem of excessive output of the power assembly 180.
