Detailed implementation manners

[0036] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0037] Referring to Figures 1 to 12 As shown, a parallelogram translation door switch structure provided by the present invention includes a door frame 1 and a sealed door 2, and the sealed door is embedded in the door frame. It further includes a mounting bracket 3, the mounting bracket is arranged on the door frame on one side of the sealed door, and several groups of slide rails 4 and sliders 5 are arranged on the bracket. The slide rails are horizontally arranged on the bracket, and the sliders are arranged on the slide rails in a sliding connection manner. A rotating mechanism 6, the number of the rotating mechanisms is the same as the number of the slide rails, one side of the rotating mechanism is fixed on the slider, and the other side of the rotating mechanism is fixed on the sealed door. A guide rail clamp 7, the guide rail clamp is arranged between the slider and the slide rail, and has two states of locking and releasing the slider and the slide rail. A rotating mechanism braking device 8, the rotating mechanism braking device is arranged on the rotating mechanism and has two states of locking and releasing the rotating mechanism; a first sensor 9, a second sensor 10 and a controller, the first sensor is used to detect the position signal of the slider, the second sensor is used to detect the position information of the rotation of the sealed door, the controller receives external door opening and closing information, and the guide rail clamp and the rotating mechanism braking device select corresponding states according to the signals of the first sensor, the second sensor and the controller.

[0038] Through the design of the slider and the slide rail, and the rotating mechanism in this embodiment, the opening of the sealed door is converted into two actions of rotation and translation, and the door opening and closing actions can be realized within a small range, which can greatly save the space required for opening and closing the door. For some cases where the door opening and closing position is very small and the space is limited, this structure can meet the door opening and closing requirements. Especially for the situation where there are objects blocking the door opening and closing position in front of the door and it is impossible to rotate the door to open and close, this structure can solve this problem.

[0039] Furthermore, a plurality of door pressing cylinders 12 are arranged at intervals on the door frame on the other side of the sealing door. The door pressing cylinders are electrically connected to the controller. A latch 12-1 is provided at the end of the door pressing cylinder close to the sealing door, and the end of the valve cylinder away from the sealing door is fixed on the door frame. The controller controls the locking and unlocking of the sealing door by the latch according to the input signal.

[0040] Specifically, the rotating mechanism includes a rotating support base 6-1, an upper cantilever bracket 6-2, a lower cantilever bracket 6-3, and a cantilever support base 6-4. The rotating support base is fixedly arranged on the sealing door, and the cantilever support base is fixedly arranged on the slider. Both ends of the upper cantilever bracket and the lower cantilever bracket are respectively installed between the rotating support base and the cantilever support base through bearings 6-5. The horizontal intervals of the upper and lower cantilever brackets at the connection points of the rotating support base are equal to the horizontal intervals at the connection points of the cantilever support base. The connection points of the upper and lower cantilever brackets on the cantilever support base are on the same horizontal plane, and the connection points of the upper and lower cantilever brackets on the rotating support base are not on the same horizontal plane. The projected lengths of the connection points at both ends of the upper and lower cantilever brackets on the horizontal plane are equal. In the illustrated embodiment, the rotating support base adopts a split structure, and the upper cantilever bracket and the lower cantilever bracket of the same rotating mechanism are respectively fixed on the split structure.

[0041] The projections of the hinge points of the upper and lower cantilever brackets on the rotating support base and the cantilever support base on the horizontal plane form a parallelogram structure. The connection lines of the hinge points of the upper and lower cantilever brackets on the rotating support base and the connection lines of the hinge points on the cantilever support base are used as the opposite parallel sides of the parallelogram structure. Through this parallelogram structure, the rotation action of the door body is realized. After the door body rotates to the preset position, the cantilever support base is translated as a whole to realize the overall translation action of the parallel structure, thereby realizing the translational opening action of the door body.

[0042] Preferably, the upper cantilever bracket adopts a straight rod structure, and the lower cantilever bracket adopts a Z-shaped structure. In the illustrated embodiment of the upper cantilever bracket and the lower cantilever bracket, bearings are installed on both sides and rotate around A1, A2, B1, and B2 respectively.

[0043] In the illustrated embodiment, the mounting bracket adopts a split design, and a set of slide rails and sliders are provided on each mounting bracket. At least one set of sliders is provided with a rail clamp, a rotating mechanism brake device, and the first sensor and the second sensor are provided on any one set of mounting brackets.

[0044] Further, obtain the running track of the slider on the slide rail according to the translation distance of the sealing door. Two first sensors are arranged on the slide rail and are directly below or above the starting end and the ending end of the running track of the slider; the second sensor is arranged on the door frame or inside the rotating mechanism to detect the position information of the sealing door. In the illustrated embodiment, the second sensor is arranged on the cantilever support base and is located between the cantilever support base and the lower cantilever bracket. During the rotation of the sealing door, the lower cantilever bracket rotates following the sealing door. When the sealing door rotates to a preset position, the projections of the lower cantilever bracket and the second sensor on the horizontal plane do not overlap.

[0045] Specifically, the rotating mechanism braking device includes a brake shaft 8-1 and a brake mechanism 8-2. The brake mechanism selects an existing structure. The brake shaft is installed on the cantilever support base. The bearings of the brake shaft and the lower cantilever bracket are arranged coaxially, and the brake shaft rotates with the rotation of the lower cantilever bracket; the brake mechanism is fixed on the cantilever support base. The brake mechanism clamps or releases the brake shaft according to the signal of the controller, so as to realize the switching between the fixed connection state and the rotating connection state of the cantilever support base and the lower cantilever support base. The brake shaft can also be arranged coaxially with the bearing of the lower cantilever bracket instead of being arranged coaxially with the bearing of the lower cantilever bracket. In addition to the rotating mechanism braking device, other structures can also be adopted, as long as the connection state between the cantilever support base and the upper cantilever bracket or between the cantilever support base and the lower cantilever bracket can be controlled to switch between the fixed connection and the rotating connection according to the signal of the controller.

[0046] Specifically, the guide rail clamp selects an existing structure. The guide rail clamp is fixed on the slider and sleeved on the guide rail. The guide rail clamp clamps or releases the slide rail according to the signal of the controller, so as to realize the opening and closing of the sealing door.

[0047] Further, a plurality of spring assemblies 13 are arranged at intervals on the contact surface between the sealing door and the frame. One end of the spring assembly is fixed on the door frame, and the other end faces the sealing door. After the pressing door cylinder releases the restriction on the sealing door, the spring assembly is used to pop out the door.

[0048] In some of the above embodiments, the sealing door is opened and closed manually. A door handle 14 is arranged on the sealing door, and the sealing door is opened and closed by applying force to the door handle.

[0049] In some other of the above embodiments, the sealing door is opened and closed by full-automatic control; a driving mechanism is arranged between the slider and the slide rail and inside the rotating mechanism. The driving mechanism is electrically connected to the controller. The controller controls the driving mechanism to realize the automatic opening and closing of the sealing door according to the signals of the first sensor, the second sensor and the input to the controller.

[0050] The working principle of the present invention:

[0051] The rotating mechanism braking device acts on the rotating mechanism. The rotating mechanism braking device includes a locked state and a released state. When the rotating mechanism braking device is in the locked state, the slider and the sealing door are equivalently fixedly connected. When the rotating mechanism braking device is in the released state, the slider and the sealing door are equivalently rotatably connected.

[0052] The guide rail clamp acts on the slider and the slide rail. The guide rail clamp includes a locked state and a released state. When the guide rail clamp is in the locked state, the slider and the slide rail are equivalently fixedly connected. When the guide rail clamp is in the released state, the slider and the slide rail are equivalently slidably connected.

[0053] The controller selects the corresponding states of the rotating mechanism braking device and the guide rail clamp according to the signals from the first sensor, the second sensor, and the external signals input to the controller.

[0054] When opening the door:

[0055] 1. The controller receives the external output door opening signal and sends the corresponding control signal. The rotating mechanism braking device is in the released state, and the guide rail clamp is in the locked state. At this time, the sealing door rotates open but cannot translate.

[0056] 2. After the sealing door rotates to a suitable position, the second sensor detects the corresponding signal and transmits it to the controller. Then the controller sends the corresponding signal. The rotating mechanism braking device is in the locked state, and the guide rail clamp is in the released state. At this time, the sealing door translates but cannot rotate.

[0057] 3. When the door is fully opened, the first sensor detects the corresponding signal and transmits it to the controller. Then the controller sends the corresponding signal. The rotating mechanism braking device is in the locked state, and the guide rail clamp is in the locked state. At this time, the sealing door cannot move.

[0058] When closing the door:

[0059] 1. The controller receives the external output door opening signal and sends the corresponding control signal. The rotating mechanism braking device is in the locked state, and the guide rail clamp is in the released state. At this time, the sealing door translates but cannot rotate.

[0060] 2. After the sealing door translates to a predetermined position, another first sensor detects the corresponding signal and transmits it to the controller. Then the controller sends the corresponding signal. The rotating mechanism braking device is in the released state, and the guide rail clamp is in the locked state. At this time, the sealing door rotates open but cannot translate.

[0061] 3. Manually close the sealing door. Then the controller receives the signal that the door body is closed. Then the controller sends the corresponding signal. The rotating mechanism braking device is in the locked state, and the guide rail clamp is in the locked state.

[0062] If a pressing door cylinder is included, corresponding signals are also sent during door opening and closing. According to the opening angle of the sealed door or the degree of translational opening, multiple first sensors and second sensors can be added. A driving mechanism can also be provided between the slider and the slide rail, as well as inside the rotating mechanism. The driving mechanism is electrically connected to the controller. The controller controls the driving mechanism to automatically open and close the sealed door according to the signals from the first sensor, the second sensor, and the signals input to the controller, thereby realizing fully automated door opening and closing.

[0063] Through the design of the slider and the slide rail, as well as the rotating mechanism, the opening of the sealed door is converted into two actions: rotation and translation. The door opening and closing actions can be realized within a small range, which can greatly save the space required for door opening and closing. For some cases where the door opening and closing position is very small and the space is limited, this structure can meet the requirements of door opening and closing. Especially when there are objects blocking the door opening and closing position in front of the door and it is impossible to rotate the door to open and close, this structure can solve this problem.

[0064] The above are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited by this. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the protection scope of the present invention.
