The first door assembly 210 and the second door assembly 220 are switchable between a closed state and an open state, and when the first door assembly 210 and the second door assembly 220 are in the closed state, the tilt beam assembly 100 is used to close a gap between the first door assembly 210 and the second door assembly 220.

The storage cabinet needs to be sealed and can be used for heat preservation or cold preservation, and the following embodiments take the storage cabinet for cold preservation as an example for illustration. The side-by-side door may be a side-by-side door, or other side-by-side door, and the first door assembly 210 and the second door assembly 220 of the side-by-side door are illustrated in fig. 1 to 12 as an example.

An embodiment of the first aspect of the present invention provides a tilt beam assembly 100 comprising: a beam body 110, the beam body 110 being adapted to be switched between a closed position and a restored position, and a drive assembly for driving the beam body 110 between the closed position and the restored position.

The beam body 110 is in the closed position, corresponding to the first door assembly 210 and the second door assembly 220 being in the closed state, at which time the beam body 110 is used to close the gap between the first door assembly 210 and the second door assembly 220. In some cases, in the closed position, the beam body 110 extends beyond the first sidewall 211 of the first door assembly 210 in the direction of the second door assembly 220. When the beam body 110 is at the recovery position, corresponding to the first door assembly 210 and the second door assembly 220 being in the open state, at this time, the user needs to open the locker, the cabinet body 300 of the locker is no longer in the sealed state, and the beam body 110 at the recovery position is shielded by the first door assembly 210, so as to prevent the beam body 110 from extending out of the first side wall 211 to affect the operation of the user.

The driving assembly includes a moving member 120 and a transmission member 130, the transmission member 130 includes a first connection portion 131, a second connection portion 132 and a third connection portion 133, the first connection portion 131 is used for being rotatably connected with the first door assembly 210, the second connection portion 132 is connected to the beam body 110, the third connection portion 133 is connected to the moving member 120, and the transmission member 130 is used for connecting the beam body 110 and the moving member 120 to transmit the driving force of the moving member 120 to the beam body 110, so as to realize the movement of the beam body 110.

The moving member 120 is adapted to drive the beam body 110 to rotate between the closed position and the restored position by moving between the first position and the second position. The moving member 120 is in the first position, the beam body 110 is in the closed position; the moving member 120 is in the second position and the beam body 110 is in the restored position.

The moving force of the moving member 120 is transmitted to the beam body 110 through the transmission member 130, thereby realizing the rotational movement of the beam body 110 with a simple structure. The line connecting the first position and the second position forms an included angle with the axis of the rotation shaft of the beam body 110. The moving part 120 can be switched between the first position and the second position by the driving force, and the moving part 120 adjusts the position and drives the beam body 110 to move without contacting the beam body 110 with the tank bladder to switch the position.

In some cases, the moving member 120 is switched between the first position and the second position by a linear motion, and the beam body 110 is rotated by a predetermined angle. The moving direction of the moving member 120 forms an angle of 90 ° with the rotation axis of the beam body 110, and it can be understood that the moving member 120 moves in a horizontal direction and the rotation axis of the beam body 110 extends in a vertical direction. Wherein the beam body 110 can be rotated 90 ° or other angle from the closed position to the restored position. Referring to fig. 9 to 12, the moving member 120 is parallel to the girder body 110 in the closed position, and the moving member 120 is perpendicular to the girder body 110 in the restored position.

Of course, the moving direction of the moving component 120 may also form an angle greater than or less than 90 ° with the rotation axis of the beam body 110, and is not strictly limited to form an angle of 90 °, and it is understood that the moving path of the moving component 120 is inclined upward or downward with respect to the horizontal direction, and the rotation adjustment of the beam body 110 around the vertical rotation axis can also be satisfied. It should be noted that the angle of the moving path of the moving member 120, which is inclined upward or downward with respect to the horizontal direction, is required to ensure that the beam body 110 can still rotate around the vertical rotation axis.

When the split doors are in the closed state, the moving member 120 is in the first position and the beam body 110 is in the closed position, and when the split doors are in the open state, the moving member 120 is in the second position and the beam body 110 is in the restored position.

When the moving member 120 moves from the first position to the second position, the third connecting portion 133 is driven to slide and rotate relative to the moving member 120, the third connecting portion 133 drives the first connecting portion 131 to move, so that the first connecting portion 131 rotates relative to the first door assembly 210, meanwhile, the first connecting portion 131 drives the second connecting portion 132 to move, that is, the transmission member 130 transmits the rotational acting force to the beam body 110, and the transmission member 130 drives the beam body 110 to slide and rotate relative to the second connecting portion 132. The beam body 110 is driven to rotate and move by the rotation of the transmission member 130, so that the beam body 110 is switched from the closed position to the return position.

Similarly, when the moving member 120 moves from the second position to the first position, the transmission member 130 and the beam body 110 move in opposite directions along the same path, so as to switch the beam body 110 from the recovery position to the closed position.

One of the first matching portion 121 and the third connecting portion 133 is provided with a first sliding slot 1211, and the other is provided with a sliding block which is suitable for sliding and rotating in the first sliding slot 1211; one of the second mating portion 111 and the second connecting portion 132 is provided with a second sliding slot 1111, and the other is provided with a slider adapted to slide and rotate in the second sliding slot 1111. The slide block is guided and limited by the sliding grooves (the first sliding groove 1211 and the second sliding groove 1111 are collectively called) to ensure that the slide block is suitable for moving along the extending direction of the sliding grooves, so as to realize the driving function. Referring to fig. 3, 4 and 9 to 12, the first engaging portion 121 is provided with an elongated first sliding slot 1211, the third connecting portion 133 is a cylindrical sliding block, the second engaging portion 111 is provided with an elongated second sliding slot 1111, and the second connecting portion 132 is a cylindrical sliding block. The sliding groove is a straight extending groove, and guides and limits the second connecting portion 132 and the third connecting portion 133 to ensure that the transmission member 130 is suitable for rotating around the axis of the first connecting portion 131.

Of course, the slide groove can also be replaced by a slide hole, and the extension direction of the slide hole is the same as that of the slide groove. The slider may be a spherical block. The sliding groove is matched with the sliding block, so that the moving component 120 and the transmission component 130 can rotate and slide relatively, and the transmission component 130 and the beam body 110 can rotate and slide relatively.

The first connecting portion 131 may be a rotating shaft or a shaft hole disposed on the transmission component 130, and in cooperation with the rotating shaft or the shaft hole, the first door assembly 210 is disposed with a shaft hole or a rotating shaft adapted to the first connecting portion 131 to ensure that the transmission component 130 is rotatably connected to the first door assembly 210. Referring to fig. 1, the first connection portion 131 is a rotation shaft.

In another embodiment (not shown), the difference from the above embodiment is that the third connecting part is a gear, the first matching part is a rack, and the moving acting force of the moving part is converted into the rotating action of the transmission part by the meshing of the first matching part and the third connecting part; meanwhile, the second connecting portion is provided with a gear, the second matching portion is a rack, and the beam body is driven to rotate through the meshing of the second connecting portion and the second matching portion, so that the beam body is switched to the closed position from the return position. Of course, the movement of the moving part is reversed, and the beam body is switched from the closed position to the return position.

It is understood that the transmission member 130 includes a first transmission portion 134 and a second transmission portion 135 connected to the first transmission portion 134, at least one of the first transmission portion 134 and the first transmission portion 134 is provided with a first connection portion 131, the first transmission portion 134 is provided with a third connection portion 133, the second transmission portion 135 is provided with a second connection portion 132, and the second transmission portion 135 extends in an arc shape in a direction from the first connection portion 131 to the second connection portion 132. The second transmission portion 135 is configured to be an arc-shaped structure, so that the second transmission portion 135 can be connected to the beam body 110, thereby preventing the second transmission portion 135 from interfering with the beam body 110, and ensuring that the beam body 110 can be accurately switched between the closed position and the return position, thereby preventing jamming. Meanwhile, for the structure with bending, the second transmission part 135 extending in an arc shape can be stressed uniformly, the structural stability of the second transmission part 135 can be ensured, and the service life of the transmission part 130 can be ensured.

In some cases, the first connection portion 131 is disposed between the first transmission portion 134 and the second transmission portion 135, and the first transmission portion 134 and the second transmission portion 135 are demarcated by a rotation axis of the first connection portion 131; alternatively, the first connection portion 131 is disposed on the first transmission portion 134, and the second transmission portion 135 is disposed on one side of the first connection portion 131, which can be selected as needed. The first transmission portion 134 and the second transmission portion 135 can be two independent parts or an integrally formed structure, and can be selected according to the requirement.

Next, the driving unit will be explained.

It can be understood that the driving assembly includes a telescopic member for connecting the moving member 120 and the first door assembly 210, the moving member 120 is adapted to be switched from the second position to the first position under the action of the telescopic member according to a door closing signal or a door closing force, the transmission member 130 transmits the movement of the moving member 120 to the beam body 110, so as to drive the beam body 110 to be switched from the return position to the closed position, and in the process of door closing, the position switching of the beam body 110 is realized, and the sealing performance of the storage cabinet after door closing is ensured.

The retractable member may be an electric control device, and the retractable member may drive the moving member 120 to move according to a door closing signal, and the retractable member extends or retracts to drive the moving member 120 to move, wherein the door closing signal may be a door closing signal of at least one of the first door assembly 210 and the second door assembly 220. The door closing signal may be obtained by detecting the position of the two opposite doors, and when the sensor detects that one of the two opposite doors is closing, the door closing signal is transmitted to the telescopic component, and the telescopic component drives the moving component 120 to switch the position; alternatively, the door closing signal may be automatically identified through the signal, for example, if the sensor identifies that the pressure of the second door assembly 220 on the moving component 120 reaches a preset threshold (for example, a pressure sensor is installed at one end of the moving component 120 facing the second door assembly 220, and the door closing signal is determined through the pressure signal of the pressure sensor), the telescopic component drives the moving component 120 to perform position switching; alternatively, the door closing signal may be input through a signal input, for example, the telescopic member drives the moving member 120 to perform position switching after receiving the door closing signal input by the user. It should be noted that how to control the electric control device can be selected according to actual needs, and detailed description is omitted here.

Based on the above, the telescopic member may comprise a motor for driving the moving member 120 to switch from the second position to the first position. Of course, the motor may drive the moving member 120 to reciprocate linearly to switch the moving member 120 from the first position to the second position. The moving member 120 may also provide assistance to open the door during the process of driving the moving member 120 to switch from the first position to the second position, so as to save more effort. The telescopic part adopts an electric control device, and can realize automatic control, so that the automation degree of the side-by-side door is higher, and the user operation is simpler.

Of course, the telescopic component is a linear motor, or the telescopic component is a structure in which a motor is matched with a transmission assembly, or the telescopic component is a cylinder, a hydraulic cylinder and the like, which can be specifically selected according to needs and are not listed one by one.

The retractable member may be a mechanical structure, and the moving member 120 may receive a door-closing force of the second door assembly 220, and the door-closing force of the second door assembly 220 is used to press the moving member 120 to retract into the first door assembly 210, and at the same time, to drive the retractable member to extend or retract.

At this time, as shown in fig. 7, 8, 10 and 12, the retractable member may be an elastic member 140 (e.g., a spring), and the moving member 120 is pressed by the second door assembly 220, so that the elastic member 140 overcomes the deformation force and the moving member 120 retracts into the first door assembly 210; when the side-by-side door is opened, the restoring force of the elastic member 140 pushes the moving member 120 to switch from the first position to the second position, so as to drive the beam body 110 to switch from the closed position to the return position, the restoring force of the elastic member 140 can provide assistance for opening the door, the door opening process is more labor-saving, the structure of the elastic member 140 is simple, the assembly and disassembly are convenient, and the cost is low. Among them, between one moving part 120 and one mounting part 150 (or the first door assembly 210), one or more elastic members 140 may be provided to ensure sufficient restoring force. As shown in fig. 7, two elastic members 140 are provided in the height direction of the moving member 120.

It should be noted that when the door-closing force of the second door assembly 220 is applied to the retractable member, the moving member 120 needs to extend out of the first door assembly 210 (in the direction of the second door assembly 220), and the door-closing force of the second door assembly 220 is received by the moving member 120 contacting with the second sidewall 221 of the second door assembly 220, and the door-closing force of the second door assembly 220 is transmitted to the retractable member, so that the retractable member extends or retracts, and the moving member 120 retracts into the first door assembly 210. When the retractable member drives the moving member 120 to move according to the door closing signal, the moving member 120 may be always kept in the first door assembly 210, or the moving member 120 may be retracted into the first door assembly 210 from a position where it extends out of the first door assembly 210, which may be selected according to the requirement.

In some cases, unlike the above-described embodiment, the driving assembly may not be provided with a telescopic member, and the user may manually drive the moving member 120 to switch between the first position and the second position.

It can be understood that, referring to fig. 1, the moving member 120 is provided with a first guide portion 122, the elastic member 140 is disposed inside the first guide portion 122, the first guide portion 122 defines a guide hole, the elastic member 140 is inserted into the guide hole, and the guide hole guides and limits the elastic member 140, so as to ensure that the moving member 120 moves in a predetermined direction and prevent the elastic member 140 from being deviated.

Or, the elastic member 140 is sleeved outside the first guide portion 122, and the first guide portion 122 is provided as a guide post, which guides and supports the elastic member 140. The end of the elastic member 140 can also be clamped on the guide post to fix the elastic member 140.

It will be appreciated that as shown in fig. 7 and 8, the telescoping member has one end connected to the moving member 120 and the other end connected to the mounting member 150, and the mounting member 150 is adapted to be connected to the first door assembly 210 to facilitate mounting of the tilt beam assembly 100 to the first door assembly 210 and also protect the telescoping member.

In some cases, moving member 120 and mounting member 150 define an enclosed space in which the telescoping member is located, and moving member 120 and mounting member 150 protect the telescoping member and also facilitate mounting of flip beam assembly 100 with first door assembly 210.

By providing the installation member 150, the installation of the installation member 150, the moving member 120 and the telescopic member can be completed in advance, and then the installation member 150 and the transmission member 130 are directly installed to the first door assembly 210. When the telescopic part is the elastic part 140, the elastic part 140 can be prevented from being lost; when the telescopic component is an electric control component, the mounting component 150 can play a role in protection, and the electric control component is prevented from being damaged in the mounting process. In some cases, the installation of the tilt beam assembly 100 is facilitated by attaching the mounting member 150 and the transmission member 130 to the first door assembly 210 after the moving member 120 is positioned on the first door assembly 210, wherein the mounting member 150 can be attached to the first door assembly 210 by snapping, magnetic attraction, welding, etc. As shown in fig. 8, the mounting member 150 is snap-fit to the first door assembly 210.

Of course, the tilt beam assembly 100 may be provided without the mounting member 150, and the telescoping member may be mounted directly to the structure of the first door assembly 210, thereby reducing the number of parts.

It can be understood that, as shown in fig. 1, 7 and 8, the mounting member 150 is provided with a second guiding portion 151, the moving member 120 is provided with a third guiding portion 123, and the third guiding portion 123 is adapted to move along the guiding direction of the second guiding portion 151, so that the mounting member 150 and the moving member 120 cooperate to guide and limit the moving path of the moving member 120, and ensure that the moving member 120 moves along the set path.

One of the second guiding portion 151 and the third guiding portion 123 is a protrusion 1231, and the other one is a groove, and the guiding is performed by the cooperation of the protrusion 1231 and the groove. As shown in fig. 1 and 8, the second guiding portion 151 is a groove, and the third guiding portion 123 is a protrusion 1231. Fig. 1 and 8 illustrate two different structures of the bump 1231.

In some cases, the second guide portion 151 and the third guide portion 123 are in surface-to-surface contact, and the stability of the surface-to-surface contact is good. Referring to fig. 1, the third guide portion 123 includes a projection 1231 and guide blocks 1232 disposed at both sides of the projection 1231, the guide blocks 1232 are disposed in plurality along the guide direction of the third guide portion 123, and the end portions of the guide blocks 1232 contact the surface of the groove, so that the contact area of the second guide portion 151 and the third guide portion 123 can be reduced to reduce friction.

Alternatively, the second guide portion 151 and the third guide portion 123 are in line-surface contact, and the contact area of the line-surface contact is small, so that the moving resistance of the moving member 120 can be reduced, and the position switching of the beam body 110 is more labor-saving. The third guide portion 123 may include a protrusion 1231 and guide blocks 1232 disposed on two sides of the protrusion 1231, the guide blocks 1232 are disposed in a plurality along the guide direction of the third guide portion 123, an arc surface is formed at an end of the guide block 1232, and the arc surface is in line-surface contact with the groove, so that friction may be reduced.

Alternatively, the second guide portion 151 and the third guide portion 123 make point-surface contact, and friction of the point-surface contact is smaller.

It can be understood that, as shown in fig. 8, when the moving member 120 is in the second position, the third guiding portion 123 is adapted to be limited to the mounting member 150, so as to position the extreme position of the moving member 120, prevent the moving member 120 from being separated from the mounting member 150, facilitate the overall disassembly and assembly of the turnover beam assembly 100, and prevent the moving member 120 from being separated from the first door assembly 210 when the turnover beam assembly 100 is mounted on the first door assembly 210.

Alternatively, when the moving member 120 is at the second position, the third guiding portion 123 is adapted to be limited by the first door assembly 210, and the moving member 120 is limited by the first door assembly 210, so as to prevent the moving member 120 from separating from the first door assembly 210. Referring to fig. 7 and 8, the first sidewall 211 of the first door assembly 210 functions as a stopper for the moving member 120 to prevent the moving member 120 from being separated from the first door assembly 210. The first sidewall 211 is a wall surface facing the second door assembly 220, a right sidewall as viewed in fig. 7.

When the moving member 120 in the second position extends out of the first door assembly 210, the inclined surface 124 is located at the outer side of the first door assembly 210, and the moving member 120 guides the second door assembly 220 through the inclined surface 124 to ensure that the first door assembly 210 and the second door assembly 220 can be opened and closed quickly. When the moving member 120 is extended outward or retracted inward with respect to the first door assembly 210, the inclined surface 124 does not contact the opening of the first sidewall 211, and resistance to extension and retraction of the moving member 120 can be reduced to allow smooth movement of the moving member 120.

As shown in fig. 1 and 9 to 12, the inclined surface 124 is a front and rear surface, the inclined surface 124 is inclined toward both sides of the moving member 120 along the first end of the moving member 120, the first end is a right end, and both sides of the moving member 120 are front and rear sides. In some cases, the upper and lower surfaces may also be provided as the inclined surface 124.
