Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, in an embodiment of the present application, a temperature-controlled self-closing device 100 is disposed between a frame portion (not shown) and a fan portion (not shown), and is configured to couple the fan portion to open and close the frame portion under an external force at a normal temperature, and to automatically lock the fan portion to the frame portion at a high temperature, so as to prevent an indoor fire from spreading outward, and finally achieve a fire-proof purpose.

It should be noted that the normal temperature state and the high temperature state mentioned above do not specifically indicate the corresponding temperature interval. The high temperature state corresponds to the highest temperature that can be sustained by a temperature sensing element (described in detail below) in the temperature-controlled self-closing device 100, and the normal temperature state is referred to as normal temperature when the temperature is relatively high, i.e., lower than the highest temperature that can be sustained by the temperature sensing element. For example, when a fire breaks out in a room in a building, the ambient temperature rises, and when the ambient temperature is 50 ℃ higher than the maximum temperature that the temperature-sensitive element bears, the temperature-sensitive element will explode automatically (at this time, when the ambient temperature is higher than 50 ℃, the state is called as a high temperature state); on the contrary, when the ambient temperature is lower than 50 ℃ (normal temperature state), the temperature sensing element is in a normal state.

The temperature-controlled self-closing device 100 comprises a slide rail 10, a structural component 20 connected with a sash, a main sliding component 30, an auxiliary sliding component 40, a temperature-sensing element 50 and an elastic component 60.

The slide rail 10 is fixed on the frame along the self-extending direction, one part of the structural component 20 is connected with the sash part, and the other part of the structural component is fixed on the frame structure, and one end of the structural component is hinged with the slide rail 10, so that the hinge point of the structural component and the slide rail 10 is wound to drive the sash part to open and close relative to the frame under the action of external force. The main sliding component 30 is connected between the other end of the structural component 20 and the sliding rail 10, and can slide along the sliding rail 10 under the action of external force, so as to limit the maximum opening angle of the fan portion relative to the frame portion. The auxiliary sliding assembly 40 is assembled on the sliding rail 10, the temperature sensing element 50 is disposed on the auxiliary sliding assembly 40, and the elastic element 60 is in an energy storage state at a normal temperature and is connected between the sliding rail 10 and the auxiliary sliding assembly 40.

At normal temperature, the temperature sensing element 50 locks the auxiliary sliding assembly 40 outside the sliding path of the main sliding assembly 30 on the slide rail 10, so as to prevent the auxiliary sliding assembly 40 from obstructing the normal sliding of the main sliding assembly 30 relative to the slide rail 10, thereby realizing the normal opening and closing operation of the fan portion relative to the frame portion.

In a high temperature state, the temperature sensing element 50 is automatically exploded, that is, the temperature sensing element 50 loses the ability of locking the auxiliary sliding assembly 40 to the slide rail 10, and the auxiliary sliding assembly 40 pushes the main sliding assembly 30 along the slide rail 10 under the elastic force of the elastic element 60 to drive the fan portion to close relative to the frame portion, that is, the fan portion is self-closed relative to the frame portion when encountering fire.

The above mentioned form of energy storage in the energy storage state of the elastic element 60 may be an energy storage state in which the elastic element 60 is elongated at the normal temperature state, or an energy storage state in which the elastic element 60 is compressed at the normal temperature state; that is, the energy storage state is a natural state relative to the elastic element 60, and only the elastic element 60 can provide a force for the auxiliary sliding element 40 to drive the main sliding element 30 to slide from the maximum opening position to the locking position after the temperature sensing element 50 is automatically exploded, which is not limited herein.

Referring to fig. 2, the slide rail 10 is generally elongated and includes a base plate 11, two side plates 12, and two folded edges 13. The two side plates 12 are formed by extending the edges of the two opposite sides of the base plate 11 towards the same direction, and the two folding edges 13 are formed by turning outwards the side of the two side plates 12 far away from the base plate 11 towards the direction of mutual deviation. At this time, the base plate 11 and the two side plates 12 define a receiving groove 110.

The structural assembly 20 comprises a bracket arm 21, a sliding rod 22, a plurality of intermediate rods 23 and a connecting rod 24. The supporting arm 21 is fixedly arranged on the fan portion, one end of the sliding rod 22 is fixed at one end, far away from the locking position of the main sliding assembly 30, of the sliding rail 10 and is fixedly arranged on the frame portion together with the sliding rail 10, the plurality of intermediate rods 23 are hinged to each other to form a multi-connecting-rod structure, the head end and the tail end of the multi-connecting-rod structure are hinged between the supporting arm 21 and the sliding rod 22 respectively, so that when external force acts on the fan portion, the supporting arm 21 is driven to open and lock relative to the base 10, and opening and closing of the fan portion relative to the. The two ends of the connecting rod 24 are respectively hinged between the bracket arm 21 and the main sliding component 30 through two riveting pieces 25, so that when an external force acts on the fan part to link the main sliding component 30 to reciprocate between the maximum opening position and the locking position along the sliding rail 10.

The maximum opening position mentioned above refers to a position where the main sliding component 30 stays on the slide rail 10 when the fan portion has the maximum opening angle relative to the frame portion; the locking position is a position where the main slide assembly 30 stays on the slide rail 10 when the fan is closed with respect to the frame. Wherein the main slide assembly 30 is closer to the structural assembly 20 in the maximum open position than in the locked position.

Referring to fig. 2 and 3, the main sliding assembly 30 includes a main sliding block 31 and a pad 33. The main sliding block 31 has a C-shaped cross section with an opening facing the sliding rail 10, and is slidably engaged with the two folding edges 13 through the opening to reciprocate between the maximum opening position and the locking position along the two folding edges 13 under the linkage of the connecting rod 24. The gasket 33 is completely wrapped in the main sliding block 31 and clamped between the main sliding block 31 and the sliding rail 10; on the one hand, the whole main sliding assembly 30 is metallic in appearance, and on the other hand, the wear of the two main sliding blocks 31 made of metal material and the sliding rail 10 due to long-term direct contact is avoided.

Referring to fig. 2 and fig. 4, specifically, a notch 330 is formed in an edge of the spacer 33, and a boss 130 is disposed at a position of the slide rail 10 matching the notch 330. When the main sliding component 30 slides along the slide rail 10 from the locking position to the maximum opening position, the boss 130 is engaged with the notch 330 in a limiting manner, so as to prevent the main sliding component 30 from continuously sliding and limit the opening angle of the fan portion relative to the frame portion.

In this embodiment, the spacer 33 has notches 330 respectively formed on two sides along the width direction of the slide rail 10 (i.e. the direction perpendicular to the extending direction of the slide rail 10), and the bosses 130 are disposed on the two folding edges 13. It is understood that in other embodiments, the positions of the notch 330 and the boss 130 may be interchanged, for example, the notch 330 is disposed on the edges of the two folding edges 13, and the boss 130 is disposed on the surface of the pad 33 facing the folding edges 13, which is not limited herein.

Referring to fig. 2, the auxiliary sliding member 40 is located at a side of the maximum opening position of the main sliding member 30 away from the locking position at the normal temperature, that is, the auxiliary sliding member 40 is disposed on the slide rail 10 between the maximum opening position and the slide rod 22, so as to ensure the normal sliding of the main sliding member 30 at the normal temperature, and push and force the main sliding member 30 to slide from the maximum opening position to the locking position at the high temperature, thereby achieving the automatic closing of the fan portion relative to the frame portion. The auxiliary slider 40 includes an auxiliary slide block 41 and a damper block 43.

The auxiliary sliding block 41 is slidably coupled to the slide rail 10 and includes an intermediate portion 411, a first sliding section 412, and a second sliding section 413. The middle portion 411 is received in the receiving cavity 110 and is hollow to form a mounting cavity 410 with an opening facing away from the 11 substrate, and the temperature sensing element 50 is coupled in the mounting cavity 410.

The first sliding section 412 and the second sliding section 413 are respectively disposed at two ends of the middle portion 411 along an extending direction of the slide rail 10, and the first sliding section 412 is disposed closer to the main sliding assembly 30 than the second sliding section 413. The first sliding section 412 and the second sliding section 413 are both C-shaped with their cross sections opening toward the slide rail 10.

The damping block 43 is configured to be fixed on the auxiliary sliding block 41 through the temperature sensing element 50 and locked with the slide rail 10 at the normal temperature state, so as to prevent the auxiliary sliding block 41 from sliding relative to the slide rail 10 under the action of an external force. Meanwhile, the damping block 43 is configured to be separated from the auxiliary sliding block 41 and the slide rail 10 in a high temperature state, so as to unlock the auxiliary sliding block 41 and the slide rail 10, and allow the auxiliary sliding block 41 to move relative to the slide rail 10 in a direction approaching the main sliding unit 30.

Specifically, the damping block 43 is substantially plate-shaped, and is fitted into the mounting chamber 410 and clamped between the temperature-sensitive element 50 and a chamber wall of the mounting chamber 410 in the normal temperature state (in the present embodiment, the damping block 43 is clamped between the temperature-sensitive element 50 and the second sliding section 413 in the normal temperature state).

In the present embodiment, the damping block 43 is substantially in an E shape with an opening facing the middle portion 411, two ends of the damping block 43 (i.e. one end of the damping block 43 locked with the slide rail 10) protruding out of the middle portion 411 protrude in a direction close to the slide rail 10 to form a locking arm 430, and the slide rail 10 and the locking arm 430 are provided with a locking opening 132 at a corresponding position. At normal temperature, the locking arm 430 is limited in the extending direction of the slide rail 10 and is inserted into the locking opening 132 to lock the auxiliary sliding block 41 relative to the slide rail 10.

In this embodiment, the damping block 43 forms a clip arm 430 on each side along the width direction of the slide rail 10 (i.e. the direction perpendicular to the extension direction of the slide rail 10), and the clip openings 132 are opened on the two folding edges 13. It is understood that in other embodiments, the positions of the latch arms 430 and the bayonets 132 can be interchanged, for example, the latch arms 430 are disposed on the edges of the two folding edges 13, and the bayonets 132 are disposed on the edges of the damping block 43 facing the folding edges 13, which is not limited herein.

Further, the two folding edges 13 are provided with notches 134 at positions corresponding to the second sliding sections 413, the first sliding sections 412 are slidably clamped outside the two folding edges 13 in a normal temperature state, and when the main sliding assembly 30 is located at the maximum opening position, the main sliding block 31 abuts against the first sliding sections 412 in the auxiliary sliding block 41; the second sliding section 413 is limited in the extending direction of the sliding rail 10 and is clamped in the opening 134. That is, the auxiliary sliding block 41 is fixed to the slide rail 10 by the engagement between the latch arm 430 and the latch opening 132 on the damping block 43, and further ensures that the auxiliary sliding block 41 can be firmly fixed to the slide rail 10 by the engagement between the second sliding section 413 and the notch 134 even when the main sliding block 31 has a sliding transition tendency (i.e. a tendency of exceeding the maximum opening position) when being subjected to a large external force, thereby strictly limiting the opening angle of the fan portion relative to the frame portion.

Further, the slide rail 10 further includes a first latch 14 protruding from the base plate 11 in the same direction as the two side plates 12. The auxiliary sliding member 40 includes a second latching member 45, and the second latching member 45 protrudes from the surface of the auxiliary sliding block 31 facing the substrate 11. The elastic element 60 is accommodated in the accommodating groove 110 and is fixed between the first engaging piece 14 and the second engaging piece 45 in a stretching or compressing manner at normal temperature, i.e. provides a pretension force for the auxiliary sliding block 31 to slide in a direction approaching the main sliding block 31.

In this embodiment, the resilient member 60 is a tension spring connected between the first catch 14 and the second catch 45. In the normal temperature state, the elastic member 60 is in a stretched state; in a high temperature state and after the temperature sensing element 50 explodes, the auxiliary sliding block 31 slides towards the direction close to the main sliding block 31 under the pulling force of the elastic element 60, and pushes the main sliding block 31 to automatically slide from the maximum opening position to the locking position.

Referring to fig. 5a to 5c, the assembly cavity 410 has a first fixing hole 4101 and a second fixing hole 4102 respectively formed on the cavity walls at the two ends of the slide rail 10 in the extending direction. The damper block 43 is provided with a guide hole 432 communicating with the second fixing hole 4102. The auxiliary sliding member 40 further includes an abutting member 47, one end of the temperature sensing element 50 sequentially passes through the guide hole 432 and the second fixing hole 4102 to be fixed on the auxiliary sliding block 41, and the abutting member 47 passes through the first fixing hole 4101 and abuts against the other end of the temperature sensing element 50, that is, the abutting member provides a pre-thrust for the auxiliary sliding block 41 to slide in a direction away from the main sliding block 31.

When the temperature sensing element 50 is in a normal temperature state (namely, when the temperature sensing element 50 is not self-exploded), the pre-thrust is greater than the pre-tension; when the temperature sensor 50 is in a high temperature state (i.e., after the temperature sensor 50 explodes automatically), the pre-pushing force acting on the auxiliary slider 41 and the damping block 43 disappears, the damping block 43 is disengaged from the temperature sensor 50 and automatically falls off from the bayonet 132 under the action of its own weight, and at this time, the auxiliary slider 41 can slide in a direction approaching the main slider 31 under the action of the pulling force F1 of the elastic element 60, and pushes the main slider 31 to slide from the maximum opening position to the locking position.

Referring to fig. 6 and 7, in one embodiment, the elastic member 60 is a compression spring connected between the first clamping member 14 and the second clamping member 45. At normal temperature, the elastic member 60 is in a compressed state; in a high temperature state and after the temperature sensing element 50 explodes, the auxiliary sliding block 31 slides towards the direction close to the main sliding block 31 under the pushing force of the elastic element 60, and pushes the main sliding block 31 to automatically slide from the maximum opening position to the locking position.

Referring to fig. 8, further, a convex hull 434 is formed on the surface of the damping block 43 facing the second sliding section 413, the convex hull 434 abuts against the surface of the second sliding section 413 facing the first sliding section 412, and the auxiliary damping block 43 is separated from the auxiliary sliding block 41 and the sliding rail 10 after the temperature sensing element 50 is exploded. Specifically, in a normal temperature state (i.e., when the temperature-sensitive element 50 is not auto-exploded), the damping block 43 and the second sliding section 413 are in point-to-surface contact through the convex hull 434; in a high temperature state (i.e. after the temperature sensing element 50 explodes automatically), the elastic element 60 still provides a pulling force F1 for the auxiliary sliding block 41 to slide close to the main sliding block 31 because the acting force on the damping block 43 disappears, and the pulling force F1 of the elastic element 60 acting on the auxiliary sliding block 41 is greater than the frictional force F2 between the bayonet 132 and the latch arm 430, so that the damping block 43 rotates around the contact point of the convex hull 434 and the second sliding section 413, and falls off from the bayonet 132 more smoothly, thereby achieving the locking effect on the auxiliary sliding block 41.

In a normal temperature state, the temperature sensing element 50 is fixedly installed in the assembling cavity 410 under the action of the abutting piece 47, and provides a pre-thrust for the auxiliary sliding block 41 to move in a direction away from the main sliding block 31; the auxiliary sliding block 41 is fixed on the slide rail 10 by the matching of the clamping arm 430 on the damping block 43 and the clamping opening 132 on the slide rail 10 and the matching of the second sliding section 413 and the notch 134 on the slide rail 10. At this time, the fan portion is linked to the main sliding component 30 to reciprocate between the maximum opening position and the locking position along the slide rail through the connecting rod 24 under the action of external force.

When encountering fire, the temperature sensing element 50 explodes automatically, the pre-thrust acting on the damping block 43 disappears, and the damping block 43 falls off freely from the slide rail 10; meanwhile, the elastic element 60 releases energy, pulls the auxiliary sliding block 41 to slide towards the direction close to the main sliding block 31, and pushes the main sliding block 31 on the sliding path of the auxiliary sliding block 41 to slide from the maximum opening position to the locking position, so that the connecting rod 24 pulls the fan part to lock relative to the frame part, thereby realizing the isolation between the indoor environment and the external environment and further achieving the fire prevention.

The embodiment of the present invention provides a door and window structure (not shown), the door and window structure includes the frame, the relative frame opening and closing the fan section and connect in the frame and the temperature control self-closing device 100 between the fan sections, because it has the whole technical characteristics of the above-mentioned temperature control self-closing device 100, so has the same technical effect as the above-mentioned temperature control self-closing device 100.
