Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] The refrigerator is a commonly used refrigeration equipment. Its sliding door body conforms to people's living habits and is therefore popular in the market. With the improvement of living standards, people's demand for the automation of refrigerator doors has increased. The refrigerator is equipped with an automatic door opening and closing device to improve the intelligence of the refrigerator and improve the user experience.

[0003] At present, in order to prevent the refrigerator from colliding with obstacles or human bodies during the opening and closing process, a photoelectric switch is set on the door of the refrigerator. The photoelectric switch detects obstacles or human bodies on the front side of the refrigerator and feeds back the detected signal to the automatic door opening and closing device to control the opening or closing of the door.

[0004] However, the sensing range of a single photoelectric switch is limited. In theory, multiple photoelectric switches need to be installed on the door body to meet the large-range detection of the door body photoelectric switch, resulting in high manufacturing costs and difficulty in manufacturing the refrigerator. In addition, there is a sensing blind spot between the two photoelectric switches, resulting in low detection accuracy of the door body photoelectric switch. The door body is easily hit by obstacles or people when it opens automatically, causing damage to the refrigerator or causing harm to the user. Utility Model Content

[0005] The main purpose of the present application is to provide a refrigerator in which the anti-collision unit has a wider sensing coverage, no sensing blind area, better protection effect and lower cost.

[0006] To achieve the above objectives, in a first aspect, the present application provides a refrigerator, comprising:

[0007] Box;

[0008] The door body is slidably connected to the box body;

[0009] Automatic switch units, part of which are arranged on the box body, and another part of which are arranged on the door body, so that the door body can be moved away from the box body, or moved closer to the box body;

[0010] An anti-collision unit is arranged on the door body, and comprises an anti-collision member and a micro switch. The micro switch is arranged on the door body, and the micro switch is electrically connected to the automatic switch unit;

[0011] Among them, when the automatic switch unit is in the starting state, the anti-collision part and the door body move synchronously relative to the box body to open the door body. When the anti-collision part moves to the position of the obstacle, the anti-collision part stops moving, and the door body moves relative to the anti-collision part, so that the micro switch is in the triggered state and the door body stops moving.

[0012] The beneficial effects of the present application are: through the setting of the anti-collision unit, the anti-collision part can stop moving immediately when it hits the user during movement, which serves as the first-level anti-collision protection of the anti-collision unit, and the torque required to prevent the anti-collision part from moving forward is small, and it will not cause harm to the user. After that, the stop signal is released through the microswitch, and the actuator drives the door body to stop, thereby preventing the door body from opening and colliding with the user. The cost is low, and touching any position of the anti-collision part will cause the anti-collision part to slide backward relative to the door body. Even if an infant or a pet stays in front of the refrigerator, the protection of the anti-collision unit will be triggered. The sensing coverage is wide, there is no sensing blind spot, the protection effect is better, and the cost is lower.

[0013] Based on the above technical solution, the present application can also be improved as follows.

[0014] In some optional embodiments, the anti-collision unit further includes a sliding assembly, the sliding assembly includes a sliding member and a sliding groove, the sliding member is extended along the moving direction of the anti-collision member, the sliding groove is extended along the sliding direction of the door body, and the moving direction of the anti-collision member is consistent with the sliding direction of the door body;

[0015] One of the sliding groove and the sliding member is arranged on the door body, and the other is arranged on the anti-collision member. The sliding member is adapted to the shape of the sliding groove, and the sliding member is inserted into the sliding groove and moves in the sliding groove.

[0016] It should be noted that the setting of the sliding assembly provides guidance for the movement between the sliding member and the door body. In addition, the sliding member and the door body can be in a connected state through structural matching of the sliding member and the sliding groove.

[0017] In some optional embodiments, the sliding member is a sliding block;

[0018] When the sliding member is arranged on the anti-collision member, the sliding member is located on the side wall of the anti-collision member and protrudes from the side wall of the anti-collision member, and the notch of the sliding groove faces the sliding member and is located on the bottom wall of the door body.

[0019] It should be noted that such a configuration allows the sliding member to fit better with the bottom of the door body, thereby making the appearance of the refrigerator more beautiful.

[0020] In some optional embodiments, the sliding member includes a first sliding portion and a second sliding portion, the first sliding portion is connected to the end of the anti-collision member, one end of the second sliding portion is connected to the first sliding portion, and the free end of the second sliding portion extends in a direction away from the end of the anti-collision member;

[0021] The cross-sectional area of ​​the first sliding portion is smaller than the cross-sectional area of ​​the second sliding portion, and the cross-sectional area is a cross-sectional area perpendicular to a direction from the first sliding portion to the second sliding portion.

[0022] It should be noted that, with such an arrangement, when the movement with the sliding groove is satisfied, the connection between the anti-collision member and the door body can be satisfied through the sliding member and the sliding groove.

[0023] In some optional embodiments, the anti-collision unit further includes a moving member and a first elastic member, the moving member is arranged at the bottom end of the door body, the moving direction of the moving member is consistent with the sliding direction of the door body, and the first elastic member is located between the inner wall of the moving member and the inner wall of the anti-collision member;

[0024] When the anti-collision component moves to the position where the blocking object is located, the anti-collision component stops moving, and the movable component moves relative to the anti-collision component under the drive of the door body, so that the first elastic component is in a compressed state.

[0025] With such arrangement, when a user or a pet appears in front of the refrigerator, the anti-collision part will hit an obstacle and will stop moving forward. When the anti-collision part moves backward relative to the door body, the distance between the inner wall of the moving part and the inner wall of the anti-collision part will gradually decrease, thereby causing the first elastic part to change from the initial natural state to a compressed state, the micro switch is triggered, the door body stops moving, and when the obstacle leaves, the elastic force of the first elastic part can reset the anti-collision part to improve the stability of the structure.

[0026] In some optional embodiments, the moving member is a bending member;

[0027] The moving part has a cavity, the cavity has a connecting hole, and the connecting hole connects the moving part and the anti-collision part, so that the first elastic part passes through the connecting hole in a natural state and is connected between the inner wall of the moving part and the inner wall of the anti-collision part.

[0028] This arrangement can improve the overall strength of the moving part. In other words, the moving part is designed to be a bent structure, which can better enhance the overall strength of the moving part.

[0029] In some optional embodiments, the anti-collision unit further includes a guide column, which is disposed in the cavity and extends along the sliding direction of the door body, and the first elastic member is a spring and is sleeved on the outer periphery of the guide column;

[0030] The guide column is a cylindrical member, and the first elastic member is compressed along the axial direction of the guide column.

[0031] It should be noted that the setting of the guide column provides a guiding function for the first elastic member to be converted from a natural state to a compressed state, or from a compressed state to a natural state, so as to prevent the first elastic member from deviating during the movement.

[0032] In some optional embodiments, the anti-collision member includes a first anti-collision member and a second anti-collision member connected to each other, and the first anti-collision member and the second anti-collision member are both frame members;

[0033] The moving part, the first elastic part and the micro switch are all located in the cavity. The first anti-collision part has an opening. The second anti-collision part covers the opening. The first anti-collision part, the second anti-collision part and the door body form a cavity.

[0034] It should be noted that the first anti-collision member and the second anti-collision member are detachable, which is convenient for disassembly and maintenance of the moving member, the first elastic member and the micro switch in the cavity. The first anti-collision member has at least two openings with different structures, one of which faces the second anti-collision member and the other faces the door body. Such a setting can reduce the volume of the anti-collision member while increasing the accommodation space of the cavity, and can reduce the weight of the anti-collision member so that it can hinder the movement of the anti-collision member with a smaller torque.

[0035] In some optional embodiments, there are multiple sliding members and multiple sliding grooves, the multiple sliding members are arranged at intervals along the length direction of the anti-collision member, and the multiple sliding grooves are arranged along the length direction of the door body;

[0036] There is at least one micro switch, and the at least one micro switch is arranged at intervals along the length direction of the door body.

[0037] It should be noted that the sliding members and sliding grooves are arranged in matching numbers and are spaced apart along the length direction of the door body to improve the structural stability.

[0038] In a second aspect, the present application also provides a refrigerator, comprising:

[0039] The box body is constructed with a refrigeration compartment;

[0040] Door body;

[0041] An automatic switch unit, the automatic switch unit is configured to open or close the door of the refrigeration compartment by itself;

[0042] The anti-collision unit is arranged on the door body. Both the anti-collision unit and the door body move relative to the box body. When the anti-collision unit moves to the position where the obstacle is located, it stops. The door body moves relative to the anti-collision unit, and the automatic switch unit controls the door body to stop.

[0043] The refrigerator provided in the present application includes: a cabinet; a door body, which is slidably connected to the cabinet; an automatic switch unit, part of the automatic switch unit is arranged on the cabinet, and the other part of the automatic switch unit is arranged on the door body, so that the door body moves away from the cabinet, or moves closer to the cabinet; an anti-collision unit, the anti-collision unit is arranged at the bottom end of the door body, the anti-collision unit includes an anti-collision part and a micro switch, and the micro switch and the automatic switch unit are electrically connected; wherein, when the automatic switch unit is in a starting state, the anti-collision part and the door body both move synchronously relative to the cabinet to open the door body, and when the anti-collision part moves to the position where the obstacle is located, the anti-collision part stops moving, and the door body moves relative to the anti-collision part, so that the micro switch is in a triggered state and the door body stops moving.

[0044] Through the setting of the anti-collision unit, the anti-collision part can stop moving immediately when it hits the user during movement. This serves as the first level of anti-collision protection of the anti-collision unit, and the torque required to prevent the anti-collision part from moving forward is small, and it will not cause harm to the user. After that, the stop signal is released through the micro switch, and the actuator drives the door body to stop, thereby preventing the door body from opening and colliding with the user. The cost is low, and touching any position of the anti-collision part will cause the anti-collision part to slide backward relative to the door body. Even if an infant or pet stays in front of the refrigerator, the protection of the anti-collision unit will be triggered. The sensing coverage is wide, there is no sensing blind spot, the protection effect is better, and the cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, 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 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 this field without creative work are within the scope of protection of the present application. All other embodiments obtained are within the scope of protection of the present application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0076] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0077] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0078] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0079] at present, Figure 1 The schematic diagram of the induction of the photoelectric switch of the refrigerator provided by the prior art is as follows: Figure 2 The schematic diagram of the induction of multiple photoelectric switches in the refrigerator provided by the prior art. Figure 1 and Figure 2As shown, in order to prevent the refrigerator from hitting obstacles or people during the opening and closing process, a photoelectric switch is set on the door of the refrigerator. The photoelectric switch detects obstacles or people in front of the refrigerator and feeds back the detected signal to the automatic door opening and closing device to control the door to open or close. However, since the sensing angle of a single photoelectric switch is 60° and the maximum sensing distance is 200mm, the maximum sensing range of a single switch is only 230mm. Considering the total width of the door, theoretically at least multiple photoelectric switches should be distributed, which is very costly. In addition, the area between the two photoelectric switches is a sensing blind area, which may cause harm to the user during the automatic door opening process.

[0080] In order to overcome the defects in the prior art, the refrigerator provided by the present application, through the setting of the anti-collision unit, can stop moving immediately when the anti-collision part hits the user during movement. This serves as the first level of anti-collision protection of the anti-collision unit, and the torque required to prevent the anti-collision part from moving forward is small, and will not cause harm to the user. After that, the stop signal is released through the micro switch, and the actuator drives the door body to stop, thereby preventing the door body from opening and colliding with the user. The cost is low, and touching any position of the anti-collision part will cause the anti-collision part to slide backward relative to the door body. Even if an infant or pet stays in front of the refrigerator, the protection of the anti-collision unit will be triggered. The sensing coverage is wide, there is no sensing blind spot, the protection effect is better, and the cost is lower.

[0081] The contents of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application more clearly and in detail.

[0083] like Figures 3 to 14 As shown, the embodiment of the present application provides a refrigerator 100, including:

[0084] The box body 110 is configured with a refrigeration compartment;

[0085] The door body 120 is slidably connected to the box body 110;

[0086] Automatic switch units, part of which are arranged on the cabinet 110, and another part of which are arranged on the door 120, so that the door 120 moves away from the cabinet 110, or moves close to the cabinet 110, thereby opening or closing the refrigeration compartment;

[0087] The anti-collision unit 130 is arranged at the bottom end of the door body 120. The anti-collision unit 130 includes an anti-collision member 131 and a micro switch 132. The micro switch 132 is electrically connected to the automatic switch unit;

[0088] Among them, when the automatic switch unit is in the starting state, the anti-collision piece 131 and the door body 120 both move synchronously relative to the box body 110 to open the door body 120. When the anti-collision piece 131 moves to the position of the obstacle, the anti-collision piece 131 stops moving, and the door body 120 moves relative to the anti-collision piece 131, so that the micro switch 132 is in the triggered state, and the door body 120 stops moving.

[0089] By setting the anti-collision unit 130, the anti-collision part 131 can stop moving immediately when it hits a user during movement. This serves as the first level of anti-collision protection of the anti-collision unit 130, and the torque required to prevent the anti-collision part 131 from moving forward is small, and it will not cause damage to the user. Then, the stop signal is released through the micro switch 132, and the actuator 150 drives the door body 120 to stop, thereby preventing the door body 120 from opening and colliding with the user. The cost is low, and touching any position of the anti-collision part 131 will cause the anti-collision part 131 to slide backward relative to the door body 120. Even if an infant or a pet stays in front of the refrigerator 100, the protection of the anti-collision unit 130 will be triggered. The sensing coverage is wide, there is no sensing blind spot, the protection effect is better, and the cost is lower.

[0090] It should be noted that each structure is described in detail below.

[0091] [Box 110]

[0092] refer to Figure 3The refrigerator 100 of the embodiment of the present application may include a box body 110 and a door body 120. The box body 110 may be configured with a refrigeration compartment. The refrigeration compartment has an opening for storing food and other items. The number of refrigeration compartments may be one or more. When the number of refrigeration compartments is more than one, the multiple refrigeration compartments may be divided into a refrigeration compartment, a freezing compartment, or a temperature-changing compartment, etc.

[0093] Exemplarily, the box body 110 may include a box shell and a box liner, wherein the box shell is used to define the outer boundary of the refrigerator 100. The box liner may be arranged in the box shell and connected to the box shell. The box liner may be recessed inward to form a refrigeration compartment. An insulation layer may be filled between the box shell and the box liner, and the insulation layer can keep the refrigeration compartment warm, thereby reducing the energy consumption of the refrigerator 100.

[0094] [Door body 120]

[0095] It should be noted that the door body 120 can be connected to the box body 110 to open or close the refrigeration compartment. One door body 120 can be provided for the same refrigeration compartment. Alternatively, two door bodies 120 can be provided for the same refrigeration compartment.

[0096] In some possible implementations of the embodiment of the present application, the door body 120 may be a first door body 121, and the first door body 121 may be rotatably connected to the cabinet 110 around the height direction of the cabinet 110. The first door body 121 may be pulled or pushed so that the first door body 121 rotates relative to the cabinet 110 to open or close the refrigeration compartment.

[0097] It should be noted that the height direction of the cabinet 110 refers to the height direction of the cabinet 110 when the refrigerator 100 is in normal use. Figure 3 The vertical direction Z shown in FIG. illustratively, the first door body 121 may be rotatably connected to the box body 110 via a hinge 1211 .

[0098] In some other possible implementations of the present application, Figures 3 to 6 As shown, the door body 120 may be a second door body 122, and the second door body 122 may be slidably connected to the cabinet 110 along the depth direction of the cabinet 110. It is the sliding direction of the second door body 122, and the second door body 122 may be pulled or pushed so that the second door body 122 slides relative to the cabinet 110 to open or close the refrigeration compartment.

[0099] It should be noted that Figure 7 The horizontal direction X shown in refractory 2 represents the sliding direction of the second door 122 and the depth direction of the box body 110 .

[0100] Specifically, the second door body 122 and the anti-collision unit 130 are both arranged to be drawn relative to the box body 110 .

[0101] The present application is described by taking the door body 120 as the second door body 122 as an example, and the door body 120 described below is the second door body 122 .

[0102] like Figure 7 As shown, in some embodiments, the second door body 122 can be slidably connected to the box body 110 through a guide rail pair 1221. The guide rail pair 1221 includes a fixed guide rail 12211 and a sliding guide rail 12212, and the fixed guide rail 12211 can be fixedly connected to the upper side of the refrigeration compartment. The sliding guide rail 12212 can be slidably connected to the fixed guide rail 12211. The second door body 122 can be connected to an end of the sliding guide rail 12212 away from the rear side wall of the refrigeration compartment. When a pulling force or a pushing force is applied to the second door body 122, the second door body 122 can drive the sliding guide rail 12212 to slide relative to the fixed guide rail 12211, thereby opening or closing the refrigeration compartment.

[0103] For example, there may be two guide rail pairs 1221, and the two guide rail pairs 1221 may be symmetrically arranged along the central plane of the height direction Z in the box body 110. The fixed guide rails 12211 in the two guide rail pairs 1221 are respectively fixedly connected to the two end side walls opposite to the refrigeration compartment, and the ends of the sliding guide rails 12212 in the two guide rail pairs 1221 facing away from the rear side wall of the refrigeration compartment are both fixedly connected to the second door body 122.

[0104] [Automatic switch unit]

[0105] The refrigerator 100 of the embodiment of the present application may further include an automatic switch unit, which can be used to automatically open or close the door body 120, thereby improving the convenience of opening and closing the door body 120 and enhancing the user experience.

[0106] In some possible implementations of the present application, the number of automatic switch units may be the same as the number of door bodies 120. That is, one automatic switch unit may be provided corresponding to each door body 120. Each automatic switch unit may automatically open or close the door body 120 corresponding thereto.

[0107] Continue to refer Figures 6 to 9 The automatic switch unit may include a driving mechanism 140 and an actuator 150. The driving mechanism 140 is used to provide a driving force. The actuator 150 may connect the driving mechanism 140 and the door body 120, and is configured to open or close the door body 120 under the action of the driving force.

[0108] The driving mechanism 140 is used to provide a driving force for the automatic opening and closing unit to open or close the door body 120 .

[0109] For example, reference Figure 8 and Fig. 9The driving mechanism 140 may include a driving motor 141, and the driving motor 141 has a rotatable output shaft, and the output shaft may be connected to the actuator 150 to provide driving force to the actuator 150. It is understandable that the driving motor 141 may be replaced by other components that can provide driving force, such as a pneumatic motor or a hydraulic motor, etc., and this embodiment of the present application will not be described in detail.

[0110] The driving mechanism 140 may further include a first worm 142 and a first worm wheel 143. The first end of the first worm 142 may be connected to the first output shaft of the driving motor 141. The first worm wheel 143 may mesh with the first worm 142 and be transmission-connected to the actuator 150. When the driving mechanism 140 is actuated, the output shaft of the driving motor 141 rotates, the output shaft drives the first worm 142 to rotate, the first worm 142 drives the first worm wheel 143 meshed therewith to rotate, and the first worm wheel 143 drives the actuator 150 to operate to open or close the door body 120. By providing the first worm 142 and the first worm wheel 143, the rotation speed of the driving force provided by the driving motor 141 can be reduced, the torque of the driving force can be increased, and the direction of the driving force can be changed to meet the driving force requirements of the actuator 150.

[0111] The automatic switch unit may further include a transmission gear train 160, which may be mounted on the housing 110. The transmission gear train 160 may include at least one first transmission gear 161, which connects the driving mechanism 140 and the actuator 150. The driving mechanism 140 may transmit the driving force to the actuator 150 through the transmission gear train 160, so that the actuator 150 operates.

[0112] Continue to refer Figures 6 to 9 In some possible implementations of the embodiments of the present application, the automatic switch unit may further include a clutch mechanism 170, which may be disposed between the drive mechanism 140 and the actuator 150, and is used to connect or disconnect the drive mechanism 140 and the actuator 150. The clutch mechanism 170 may also be configured to arbitrarily control the timing of connecting or disconnecting the drive mechanism 140 and the actuator 150, so as to increase the function of the automatic switch unit and improve the user experience.

[0113] It is understandable that by providing the clutch mechanism 170, the automatic switch unit can also achieve other functions, which will not be described in detail in the embodiments of the present application.

[0114] In some embodiments, continue to refer to Figures 6 to 9The clutch mechanism 170 includes a clutch motor 171, a second worm 172, a second worm wheel 173, a first clutch gear 174, a second clutch gear 175, a third clutch gear 176 and a clutch rack 177. The second worm wheel 173 is meshed with the second worm 172. When the output shaft of the clutch motor 171 rotates, the second worm 172 is driven to rotate, the second worm 172 drives the second worm wheel 173 to rotate, the second worm wheel 173 drives the clutch rack 177 to move, and the clutch rack 177 drives the third clutch gear 176 to rotate, so that the first protrusion of the sliding key set on the second clutch gear 175 is disengaged from or engaged with the key slot of the first clutch gear 174, and the clutch enters a disengaged state or an engaged state.

[0115] The actuator 150 may include an actuator rack 151. When the clutch mechanism 170 is in an engaged state, the clutch mechanism 170 enables the driving mechanism 140 and the actuator 150 to be connected in transmission. The driving mechanism 140 can transmit the driving force to the actuator 150 through the clutch mechanism 170, so that the actuator rack 151 can drive the door body 120 away from or close to the box body 110, thereby automatically opening or closing the door body 120. When the clutch mechanism 170 is in a disengaged state, the clutch mechanism 170 disconnects the driving mechanism 140 and the actuator 150. The user can manually open or close the door body 120, and the force applied by the user to the door body 120 to open or close the door body 120 will not be transmitted to the driving mechanism 140. In this way, the automatic switch unit can be compatible with the automatic door opening and closing function and the manual door opening and closing function, which increases the function of the automatic switch unit and improves the user experience.

[0116] [Anti-collision unit 130]

[0117] It should be noted that, through the setting of the anti-collision unit 130, the anti-collision part 131 can stop moving immediately when it hits a user during movement. Even if an infant or a pet stays in front of the refrigerator 100, the protection of the anti-collision unit 130 will be triggered. The sensing coverage is wide, there is no sensing blind spot, the protection effect is better, and the cost is lower.

[0118] It should be noted that the micro switch 132 refers to a switch having a small contact interval and a snap-action mechanism, a contact mechanism that performs a switching action with a specified stroke and a specified force, and a trigger point on the outside.

[0119] Fig.15 This is a schematic diagram of the assembly of the door body and the anti-collision unit in the refrigerator provided in the embodiment of the present application. Fig.16 An exploded view of the first perspective of the assembly of the door body and the anti-collision unit in the refrigerator provided in the embodiment of the present application, Fig.17 An exploded view from a second perspective of the assembly of the door body and the anti-collision unit in the refrigerator provided in an embodiment of the present application, Fig.18An exploded view of the assembly of the door body and the anti-collision unit of the refrigerator provided in the embodiment of the present application from a third perspective, Fig.19 A cross-sectional view of the assembly of the door body and the anti-collision unit of the refrigerator provided in an embodiment of the present application.

[0120] like Figures 10 to 19 As shown, in some embodiments, the micro switch 132 is detachably mounted on the door body 120, for example, by using bolts, snaps, etc., to facilitate subsequent disassembly and maintenance.

[0121] When the automatic switch unit is in the starting state, that is, the clutch mechanism 170 is in the engaged state, and the door body 120 is in the open state under its action. Since the anti-collision member 131 is movably installed at the bottom end of the door body 120, at the beginning, Fig.11 and Fig.13 As shown, the door body 120 and the anti-collision member 131 both move in the depth direction of the box body 110, and are set to push and pull. When the anti-collision member 131 touches an obstacle, it stops moving further. At this time, the obstacle prevents the anti-collision member 131 from moving, which is the first level of anti-collision protection. Fig.12 As shown. Then Fig.14 As shown, the door body 120 continues to move forward, and then the anti-collision member 131 moves in the opposite direction relative to the door body 120, the micro switch 132 is triggered, releasing a stop signal, and then the actuator 150 stops, that is, the door body 120 stops, which is the second level of anti-collision protection.

[0122] In addition, it should be noted that the obstacle is generally the user's foot, that is, when the anti-collision member 131 touches the user's foot, it will stop moving forward. Since the anti-collision member 131 is small in size, the torque required to hinder the forward movement is also small, and it will not cause damage to the user's body.

[0123] like Fig.16 and Fig.18 As shown, in some optional embodiments, the anti-collision unit 130 further includes a sliding assembly 133, the sliding assembly 133 includes a sliding member 1331 and a sliding groove 1332, the sliding member 1331 is extended along the moving direction of the anti-collision member 131, the sliding groove 1332 is extended along the sliding direction of the door body 120, and the moving direction of the anti-collision member 131 is consistent with the sliding direction of the door body 120;

[0124] One of the sliding groove 1332 and the sliding member 1331 is arranged on the door body 120 , and the other is arranged on the anti-collision member 131 . The sliding member 1331 is adapted to the shape of the sliding groove 1332 . The sliding member 1331 is inserted into the sliding groove 1332 and moves in the sliding groove 1332 .

[0125] Exemplarily, the sliding groove 1332 can be set on the door body 120, and the sliding member 1331 can be set on the anti-collision member 131; of course, the sliding groove 1332 can be set on the anti-collision member 131, and the sliding member 1331 can be set on the door body 120.

[0126] It should be noted that the setting of the sliding component 133 provides guidance for the movement between the sliding member 1331 and the door body 120. In addition, the sliding member 1331 and the sliding groove 1332 can be matched with each other in the structure, so that the sliding member 1331 and the door body 120 can be in a connected state.

[0127] In some embodiments, the sliding member 1331 can be fixedly or detachably installed on the anti-collision member 131 , facing the sliding groove 1332 , inserted into the sliding groove 1332 , and moved along the sliding groove 1332 .

[0128] Exemplarily, when the automatic switch unit is in the starting state, that is, the clutch mechanism 170 is in the engaged state, the door body 120 is in the open state under its action. Since the anti-collision member 131 is movably installed at the bottom end of the door body 120, at the beginning, the anti-collision unit 130 and the door body 120 both move in the depth direction of the box body 110. When the anti-collision member 131 touches an obstacle, it stops moving. At this time, the obstacle hinders the movement of the anti-collision member 131, and the door body 120 continues to move forward. The sliding member 1331 moves in the sliding groove 1332, so that the anti-collision member 131 moves in the opposite direction relative to the door body 120, and the micro switch 132 is triggered to release the stop signal, and then the actuator 150 stops, that is, the door body 120 stops.

[0129] like Fig.16 and Fig.18 As shown, in some optional embodiments, the sliding member 1331 is a sliding block;

[0130] When the sliding member 1331 is disposed on the anti-collision member 131 , the sliding member 1331 is located on the side wall of the anti-collision member 131 and protrudes from the side wall of the anti-collision member 131 . The notch of the sliding groove 1332 faces the sliding member 1331 and is located on the bottom wall of the door body 120 .

[0131] It should be noted that such a configuration allows the sliding member 1331 to fit better with the bottom of the door body 120, thereby making the appearance of the refrigerator 100 more beautiful.

[0132] In some embodiments, the sliding member 1331 and the anti-collision member 131 are connected by an integrated connection. In other embodiments, the sliding member 1331 and the anti-collision member 131 can also be connected by other connection methods. As long as the connection method can fix the sliding member 1331 and the anti-collision member 131, the purpose of this embodiment can be achieved. Here, there is no restriction on the connection method between the sliding member 1331 and the anti-collision member 131.

[0133] In some optional embodiments, such as Fig.16 , Fig.18 as well as Fig.19 As shown, the sliding member 1331 includes a first sliding portion 13311 and a second sliding portion 13312, the first sliding portion 13311 is connected to the end of the anti-collision member 131, one end of the second sliding portion 13312 is connected to the first sliding portion 13311, and the free end of the second sliding portion 13312 extends in a direction away from the end of the anti-collision member 131;

[0134] Among them, the cross-sectional area of ​​the first sliding part is smaller than the cross-sectional area of ​​the second sliding part, and the cross-section is a cross-sectional area perpendicular to the direction from the first sliding part to the second sliding part. That is, along the length direction of the anti-collision part 131, the extension length of the second sliding part 13312 is greater than the extension length of the first sliding part 13311, and along the length direction of the door body 120, the extension length of the bottom of the sliding groove 1332 is greater than the extension length of the groove mouth of the sliding groove 1332.

[0135] It should be noted that the length direction of the anti-collision member 131 is consistent with the length direction of the door body 120, which is easy to understand. Fig.18 and Fig.19 As shown, Y represents the length direction of the anti-collision component 131 and the length direction of the door body 120 .

[0136] Along the length direction of the anti-collision member 131, the extension length of the second sliding part 13312 is greater than the extension length of the first sliding part 13311, so that when it moves with the sliding groove 1332, the connection between the anti-collision member 131 and the door body 120 can be met through the sliding member 1331 and the sliding groove 1332.

[0137] That is to say, the sliding component 133 may be a dovetail-type guiding structure, for example, the sliding member 1331 may be a dovetail tenon, and the sliding groove 1332 may be a dovetail groove, which has better guiding effect and stability.

[0138] In other embodiments, the sliding member 1331 may be a slider, the sliding groove 1332 may be a slide rail, the slider may move on the slide rail along the length direction of the slide rail, etc. The dovetail guide structure adopted in this embodiment has a simpler structure and lower cost.

[0139] In some optional embodiments, continue to refer to Figures 15 to 19 The anti-collision unit 130 further includes a moving member 134 and a first elastic member 135. The moving member 134 is disposed at the bottom end of the door body 120. The moving direction of the moving member 134 is consistent with the sliding direction of the door body 120. The first elastic member 135 is located between the inner wall of the moving member 134 and the inner wall of the anti-collision member 131.

[0140] When the anti-collision member 131 moves to the position where the blocking object is located, the anti-collision member 131 stops moving, and the moving member 134 moves relative to the anti-collision member 131 driven by the door body 120 , so that the first elastic member 135 is in a compressed state.

[0141] It should be noted that the moving member 134 can be fixedly arranged at the bottom end of the door body 120, wherein the moving direction of the moving member 134 is consistent with the sliding direction of the door body 120. Fig.15 The X in.

[0142] When the automatic switch unit is in the starting state, that is, the clutch mechanism 170 is in the engaged state, the door body 120 is opened under its action, and accordingly, as the door body 120 moves, the anti-collision member 131 is also opened relative to the box body 110. At this time, the anti-collision member 131 and the door body 120 can be regarded as being in a relatively static state, and its first elastic member 135 is naturally located between the inner wall of the moving member 134 and the inner wall of the anti-collision member 131. When a user or a pet appears in front of the refrigerator 100, the anti-collision member 131 at this time encounters an obstacle and will stop moving forward, wherein the forward movement is the movement of the anti-collision member 131 away from the box body 110. 0; since the anti-collision member 131 has stopped moving, and the door body 120 continues to move forward under the push of the actuator 150, the anti-collision member 131 and the door body 120 produce relative displacement at this time, that is, the anti-collision member 131 moves backward relative to the door body 120, and then the distance between the inner wall of the movable member 134 and the inner wall of the anti-collision member 131 gradually becomes smaller, thereby causing the first elastic member 135 to change from the initial natural state to the compressed state, the micro switch 132 is triggered, the door body 120 stops moving, and when the obstacle leaves, the elastic force of the first elastic member 135 can reset the anti-collision member 131.

[0143] like Fig.16 and Fig.17 As shown, in some optional embodiments, the moving member 134 is a bending member;

[0144] The moving member 134 has a cavity having a connecting hole 1341 , which connects the moving member 134 and the anti-collision member 131 , so that the first elastic member 135 passes through the connecting hole 1341 in a natural state and is connected between the inner wall of the moving member 134 and the inner wall of the anti-collision member 131 .

[0145] In some embodiments, the movable member 134 is a plate-like member, which is bent to form a bent member and has a notch in the height direction of the box body 110. The connecting hole 1341 faces the inner wall of the anti-collision member 131, so that the first elastic member 135 is connected between the inner wall of the movable member 134 and the inner wall of the anti-collision member 131 in a natural state.

[0146] Exemplarily, the movable member 134 has two side walls, which are arranged relative to each other in the length direction of the anti-collision member 131. Such an arrangement improves the overall strength of the movable member 134. In other words, the movable member 134 is designed to be a bent structure, which can better enhance the overall strength of the movable member 134.

[0147] In some optional embodiments, such as Figures 15 to 18 As shown, the anti-collision unit 130 further includes a guide column 136, which is disposed in the moving member 134 and extends along the sliding direction of the door body 120, and the first elastic member 135 is a spring and is sleeved on the outer periphery of the guide column 136;

[0148] The guide post 136 is a cylindrical member, and the first elastic member 135 is compressed along the axial direction of the guide post 136 .

[0149] It should be noted that the guide column 136 is provided to provide guidance for the first elastic member 135 to be converted from a natural state to a compressed state, or vice versa, so as to prevent the first elastic member 135 from deviating during movement.

[0150] In some embodiments, the guide column 136 is fixedly mounted on the side wall of the movable member 134 and extends along the sliding direction of the door body 120, wherein the guide column 136 can extend to the plane where the protruding connecting hole 1341 is located, and of course, it may not protrude from the plane where the connecting hole 1341 is located, that is, it does not protrude from the end face of the side wall set in the length direction of the anti-collision member 131.

[0151] like Figures 15 to 17 As shown, in some optional embodiments, the anti-collision member 131 includes a first anti-collision member 1311 and a second anti-collision member 1312 connected to each other, and the first anti-collision member 1311 and the second anti-collision member 1312 are both frame members;

[0152] The moving member 134 , the first elastic member 135 and the micro switch 132 are all located in the cavity. The first anti-collision member 1311 has an opening. The second anti-collision member 1312 covers the opening. The first anti-collision member 1311 , the second anti-collision member 1312 and the door body 120 form a cavity.

[0153] It should be noted that the first anti-collision member 1311 and the second anti-collision member 1312 are detachable, which is convenient for disassembly and maintenance of the moving member 134, the first elastic member 135 and the micro switch 132 in the cavity. The first anti-collision member 1311 has at least two openings with different structures, one of which faces the second anti-collision member 1312 and the other faces the door body 120. Such a setting can reduce the volume of the anti-collision member 131 while increasing the accommodation space of the cavity, and can reduce the weight of the anti-collision member 131, so that it can hinder the movement of the anti-collision member 131 with a smaller torque.

[0154] like Figures 15 to 19 As shown, in some optional embodiments, there are multiple sliding members 1331 and multiple sliding grooves 1332, multiple sliding members 1331 are arranged at intervals along the length direction of the anti-collision member 131, and multiple sliding grooves 1332 are arranged along the length direction of the door body 120;

[0155] There is at least one micro switch 132 , and the at least one micro switch 132 is arranged at intervals along the length direction of the door body 120 .

[0156] It should be noted that the sliding member 1331 and the sliding groove 1332 are mutually arranged, and both are multiple. Correspondingly, the moving member 134 and the first elastic member 135 are also multiple.

[0157] Specifically, the number of sliding members 1331, sliding grooves 1332, moving members 134 and first elastic members 135 are matched with each other and are spaced apart along the length direction of the door body 120 to improve the structural stability. Considering that the greater the number, the greater the friction, in this embodiment, the width of the door body 120 is 860 mm, and the number of sliding members 1331 and sliding grooves 1332 can be selected as 3 to 5 groups.

[0158] The refrigerator provided by the embodiment of the present application includes: a cabinet; a door body, which is slidably connected to the cabinet; an automatic switch unit, part of the automatic switch unit is arranged on the cabinet, and the other part of the automatic switch unit is arranged on the door body, so that the door body moves away from the cabinet, or moves closer to the cabinet; an anti-collision unit, the anti-collision unit is arranged at the bottom end of the door body, the anti-collision unit includes an anti-collision part and a micro switch, and the micro switch and the automatic switch unit are electrically connected; wherein, when the automatic switch unit is in a starting state, the anti-collision part and the door body both move synchronously relative to the cabinet to open the door body, and when the anti-collision part moves to the position where the obstacle is located, the anti-collision part stops moving, and the door body moves relative to the anti-collision part, so that the micro switch is in a triggered state and the door body stops moving.

[0159] Through the setting of the anti-collision unit, the anti-collision part can stop moving immediately when it hits the user during movement. This serves as the first level of anti-collision protection of the anti-collision unit, and the torque required to prevent the anti-collision part from moving forward is small, and it will not cause harm to the user. After that, the stop signal is released through the micro switch, and the actuator drives the door body to stop, thereby preventing the door body from opening and colliding with the user. The cost is low, and touching any position of the anti-collision part will cause the anti-collision part to slide backward relative to the door body. Even if an infant or pet stays in front of the refrigerator, the protection of the anti-collision unit will be triggered. The sensing coverage is wide, there is no sensing blind spot, the protection effect is better, and the cost is lower.

[0160] In addition, if Figures 3 to 19 As shown, the embodiment of the present application further provides a refrigerator 100, comprising:

[0161] Box 110;

[0162] Door body 120;

[0163] An automatic switch unit, the automatic switch unit is configured to open or close the refrigeration compartment by itself using the door body 120;

[0164] The anti-collision unit 130 is arranged at the bottom end of the door body 120. The anti-collision unit 130 and the door body both move relative to the box body. When the anti-collision unit moves to the position of the obstacle, it stops. The door body moves relative to the anti-collision unit, and the automatic switch unit controls the door body to stop.

[0165] The refrigerator provided in the embodiment of the present application, through the provision of an anti-collision unit, can stop moving immediately when the anti-collision piece hits a user during movement. This serves as the first-level anti-collision protection of the anti-collision unit, and the torque required to prevent the anti-collision piece from moving forward is small, and will not cause harm to the user. Thereafter, a stop signal is released through the microswitch, and the actuator drives the door body to stop, thereby preventing the door body from opening and colliding with the user. The cost is low, and touching any position of the anti-collision piece will cause the anti-collision piece to slide backward relative to the door body. Even if an infant or a pet stays in front of the refrigerator, the protection of the anti-collision unit will be triggered. The sensing coverage is wide, there is no sensing blind spot, the protection effect is better, and the cost is lower.
