As described in the background of the invention, the safety of the existing automatic revolving door and the passing experience of people through the revolving door need to be further improved. In the process of implementing the present disclosure, the applicant finds that the potential safety hazard points are as follows:

A. a gap between the rotary door body and the ground clamps a person;

B. people collide with people or people collide with the door in the rotating door body area;

the main reason why the conventional automatic revolving door has the above technical problems is that the conventional automatic revolving door moves relative to the ground, and in order to realize the relative movement, a gap is inevitably formed between the revolving door body 100 and the ground, and a brush is generally arranged at the gap, but the brush is soft after all, so that the technical problem a cannot be fundamentally solved; moreover, because the existing automatic revolving door moves relative to the ground, the passerby needs to walk along with the door after entering the revolving door, and the technical problem B can occur when the number of passerby is large or the revolving door is suddenly stopped.

In view of the above technical problems, the applicant found that the above technical problems do not occur if only a lower rotary type rotary door is adopted, that is, a support frame which can synchronously rotate with a rotary door body is arranged below the rotary door body; in other words, the passer-by enters the revolving door and stands up, and then rotates along with the revolving door and the supporting frame, so that the technical problem cannot occur.

Moreover, the applicant has carried out intensive research on various automatic revolving doors in order to realize the technical scheme, and the research process and the newly found problems are as follows:

for the two-wing, three-wing and four-wing automatic revolving door with the waffle cover 800, there are two driving forms, one is that the track 140 is arranged around the upper part of the revolving door body 100, the track 140 is supported by a plurality of upright posts 202 (generally 6-8) fixed on the fixed door body 200, referring to fig. 7, a plurality of wheels 600 matched with the track 140 are arranged at the top of the revolving door body 100, wherein 2 wheels 600 are driving wheels driven by a driving mechanism, and the rest wheels 600 are driven wheels; the driving mechanism drives the driving wheel to rotate and then drives the driven wheel to rotate, and accordingly, the rotating door body 100 rotates relative to the fixed door body 200 to achieve opening and closing of the rotating door. The second driving mode is that a driving mechanism (such as a driving motor) is arranged in the middle of the interior of the cover 800, and a central output shaft of the driving mechanism directly drives the rotating door body 100 to rotate, so that the rotating part (including the rotating door body 100 and the decoration attached to the rotating door body 100) rotates around the output shaft, and the opening and closing of the rotating door are realized.

For the three-wing and four-wing automatic revolving door without the cover 800, the driving form is the third driving form, that is, a driving mechanism (such as a driving motor) is arranged in the pit, and the central output shaft directly drives the revolving door body 100 to rotate, so that the revolving part (including the revolving door body 100 and the decorations attached to the revolving door body 100) rotates around the output shaft, thereby realizing the opening and closing of the revolving door.

Two-wing automatic revolving door with the cover 800 adopts a first driving mode, referring to fig. 1 and fig. 2, because the two-wing automatic revolving door is generally provided with the vertical hinged door 120 in the middle, the vertical hinged door 120 is opened to play a role in guiding flow in case of emergency, but the arrangement of the vertical hinged door 120 also limits that the revolving door cannot adopt a second driving mode or a third driving mode; the following problems exist with the revolving door adopting the first driving form:

(1) the track 140 is not only used as a rotary carrier of the rotary door body 100, but also responsible for supporting the weight of all the rotary door bodies 100 and the ornaments attached to the rotary door bodies 100, namely the existing rotary door has higher requirement on the strength of the track 140;

(2) the size (diameter and height) of the revolving door is also greatly limited due to the weight of the revolving part; for example, the size of the commercial two-wing automatic revolving door with the Chinese doughnut 800 can be limited to the range of 4800mm in diameter and 4500mm in height because of the weight of the revolving part;

(3) because the rail 140 has only 6-8 support points, the stability is insufficient in the positions without support points;

(4) when the rotating part is supported for a long time to run, the verticality of the upright column 202 and the levelness of the track 140 are changed, so that the integral structure is unstable;

(5) because all the driving mechanisms, the control mechanisms and the power transmission mechanisms are arranged in the upper part of the canopy 800, the maintenance and the repair are very difficult, the maintenance efficiency is low, and the work safety influence of maintenance personnel is large.

The three-wing and four-wing automatic revolving door with the canopy 800 has a large number of driving forms two because the middle vertical hinged door 120 does not need to be arranged, referring to fig. 3 and 4, the driving form two does not need to be provided with the rail 140, but the revolving door adopting the driving form two still has the following problems except the problem (5):

(6) the power output point of the product is at the central position, and the speed and the moment of the edge of the door wing can be increased along with the increase of the diameter of the product; in the using process, the door wing has larger stroke when in emergency braking, and the human body injury is caused by the larger force when the edge of the door wing hits the human body; meanwhile, the door wing glass is easy to break when braking due to inertia, so that property loss and personnel injury are caused;

(7) the size (diameter and height) of the revolving door is also greatly limited due to the torque of one driving motor 500 and the weight and inertia of the rotating part; for example, the size of the three-wing and four-wing automatic revolving door with the Chinese doughnut 800 on the market can be limited to the range of the diameter less than or equal to 3600mm and the height less than or equal to 3500 mm.

The three-wing and four-wing automatic revolving door without the canopy 800, referring to fig. 5 and 6, has no space for accommodating a driving mechanism (e.g. a driving motor) at the top, and can only place the driving mechanism in the pit, i.e. adopt the driving form three, and in addition to the problem (6) of the above problem (5), the following problems still exist:

(8) the size (diameter and height) of the revolving door is also greatly limited due to the torque of one driving motor 500 and the weight and inertia of the rotating part; for example, the size of the three-wing and four-wing automatic revolving door without the Chinese character 'hua' cover 800 on the market can be limited to the range of the diameter less than or equal to 3200mm and the height less than or equal to 3200 mm.

Due to the technical problems (1) to (8), the automatic revolving door in the prior art is easy to have high operation noise (exceeding a normal range) and unstable operation, which causes operation failure and aggravated equipment accessory consumption.

Further, the applicant has found that the above-mentioned technical problems (1) to (8) can be solved by using the lower rotary type automatic rotary door.

Further alternatively, referring to fig. 12 and 13, a guard plate 904 may be installed at a gap between the trough 900 and the ground to prevent impurities from falling into the trough.

Further optionally, the drive mechanism is a drive motor 500.

The automatically rotating door of this embodiment is rotation down, and the revolving door body 100 can be along with support frame 400 relative ground motion together, and after the sensor perception arrived the passerby, the revolving door began to rotate, and the passerby got into standing behind the revolving door and decides, and actuating mechanism drive wheel 600 rotates along ground rail 300, and support frame 400, floor 700, the revolving door body 100 carry the passerby and rotate to the passerby person and walk out the revolving door relatively ground together.

According to the lower rotary type rotating door, because the rotary door body 100, the support frame 400 and the floor 700 rotate together relative to the ground, a gap is not required to be arranged between the rotary door body 100 and the floor 700, so that the problem that people are clamped by the gap between the conventional rotary door body 100 and the ground can be effectively avoided, and the technical problem A is solved; in addition, after a person who lets go enters the revolving door, the person can rotate along with the revolving door as long as a proper position is found to stand, the inherent thinking of the existing revolving door that people walk along with the door is thoroughly changed, the problem that people collide in the area of the existing revolving door body 100 or people collide in the door is effectively solved, and the technical problem B is solved. The solution of this embodiment revolving door to technical problem A, B has effectively improved automatic revolving door's the security of passing through and the experience of passing through.

In addition, the rail 140 of the embodiment is the ground rail 300, which is directly fixed on the ground or the bottom surface of the ground trough 900, and has good stability, the ground rail 300 is only used as a rotation carrier of the rotating door body 100, and the weight of the rotating door body 100 and the ornament attached to the rotating door body 100 is transferred to the ground or the bottom surface of the ground trough 900 through the ground rail 300, so that the requirement on the strength of the rail 140 is reduced, and meanwhile, the deformation amount of the related structure is small, thereby solving the technical problems (1), (3) and (4).

Furthermore, the floor 700, the supporting frame 400, the wheels 600, the driving mechanism and the related control mechanism, and the power transmission mechanism are all located on the ground or in the ground groove 900, the maintenance and the repair are all performed on the ground, the maintenance efficiency is improved, and the maintenance personnel do not need to perform overhead operation any more, and the safety is guaranteed, thereby solving the technical problem (5).

In addition, since the power output point of the revolving door in this embodiment is located at the edge of the revolving door 100, the speed of the whole revolving door is relatively even and the moment is small compared with the case where the power output point is located at the center of the revolving door 100, the braking distance of the revolving door 100 is short during emergency braking, and the occurrence of injuries to passers-by and the breakage and damage of the glass itself due to emergency stop or inertia is reduced, thereby solving the technical problem (6).

Moreover, due to the change of the driving form of the embodiment, the specification of the revolving door can be increased on the basis of the existing revolving door, for example, under the condition that the power of the driving mechanism is equivalent to that of the existing automatic revolving door, the size of the two-wing, three-wing and four-wing automatic revolving door in the embodiment can be 6000mm in diameter and 5000mm in height; moreover, according to the requirement, the power of the driving mechanism can be increased, and then the size of the automatic revolving door is increased; thereby solving the technical problems (2), (7) and (8).

In some embodiments, a ceiling 110 is disposed on the top of the rotary door body 100; furthermore, the size of the rotary door 101 and the installation manner of the ceiling 110 are different according to the type of the rotary door (for example, two-wing automatic rotary door, three-wing automatic rotary door, four-wing automatic rotary door, and various rotary doors are divided into two types, i.e., cover buckle 800 and non-cover buckle 800).

For example, for a two-wing automatic revolving door, the revolving door leaf 101 is installed at the edge of the upper surface of the supporting frame 400, and the arc length of the single-side revolving door leaf 101 is 1/3 of the circumference of the supporting frame 400, which can be specifically set according to the requirements on the site; in order to install the ceiling 110 above the rotary door body 100 and increase the mechanical strength of the rotary door body 100, the upright posts 202 can be installed in the middle and at the two sides of the rotary door leaf 101, safety rubber strips are coated outside the upright posts 202, and the ceiling 110 and the horizontal door installation cross beam 130 can be further installed on the upright posts 202;

for example, for a three-wing automatic revolving door, the length of the revolving door leaf 101 is the length of the radius of the support frame 400, and the length can be specifically set according to the field requirement; a ceiling 110 is installed above the rotary door leaf 101;

for example, for a four-wing automatic revolving door, the length of the revolving door leaf 101 is the length of the radius of the support frame 400, and the length can be specifically set according to the field requirement; above the rotating door leaf 101 a ceiling 110 is mounted.

In some embodiments, the center position of the cover 800 is connected with the center position of the rotary door body 100 through a rotary shaft or a rotary bearing, so as to ensure the stability of the rotation of the rotary door.

Further alternatively, according to different types of the revolving door (e.g., three-wing or four-wing automatic revolving door), the lower center position of the revolving door body 100 and the center position of the supporting frame 400 may be connected by a revolving shaft or a revolving bearing to ensure the stability of the revolving door.

In some embodiments, in the existing two-wing automatic revolving door, the included angle a between the adjacent edges of the two fixed door leaves 201 and the center of the revolving circle is 60 ° as shown in fig. 2; that is, the included angle a of the conventional two-wing automatic revolving door is as small as 60 °, in other words, the angle reserved for the passer-by to enter the area of the revolving door body 100 is only 60 °, and the problem that the passer-by is caught or collided when entering the area of the revolving door body 100 often occurs due to the limited entering space. For this reason, in order to reduce the gravity of the rotating door body 100 and further reduce the pressure of the rotating door body 100 on the rail 140, the radian of the fixed door leaf 201 is generally greater than the radian of the rotating door leaf 101, wherein the radian of each fixed door leaf 201 is 120 °, and the radian of each rotating door leaf 101 is 60 °, so that a sealed closing space can be formed.

However, the driving form of the automatic revolving door of the present disclosure is changed without paying special attention to the gravity of the revolving door body 100, the radian of each fixed door leaf 201 can be set to 60-90 °, the radian of each revolving door leaf 101 is set to 90-120 °, in other words, the included angle a between the adjacent edges of the two fixed door leaves 201 and the center of the revolving circle is 90-120 °; for example, when the arc degree of each fixed door leaf 201 is set to 60 °, the arc degree of each rotating door leaf 101 may be set to 120 °, referring to fig. 16, in other words, the included angle a between the adjacent edges of two fixed door leaves 201 and the center of the rotating circle is 120 °, the entrance angle left to the passerby is increased, so as to increase the safety.

The disclosed embodiments are intended to embrace all such alternatives, modifications and variances which fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalents, improvements, and the like that may be made within the spirit and principles of the embodiments of the disclosure are intended to be included within the scope of the disclosure.
