[0034] Sliding door structures are suitable for scenarios such as high-rise balconies or kitchens. They typically include a door frame with a track and a sliding door that is slidably installed on the track. The door frame is installed in the doorway, and the sliding door can slide on the track to open or close. However, in related technologies, sliding doors are prone to bounce open due to excessive force during the closing process, which affects the user experience.
[0035] In response to this problem, refer to Figures 1-3 This utility model provides a door closing device that can prevent the sliding door 11 from impacting and rebounding, thereby achieving the slow closing of the sliding door 11.
[0036] Specifically, the door closing device provided in this embodiment includes a microprocessor and a stress sensor, an acceleration sensor, and a deceleration module, which are respectively connected to the microprocessor via signals. The acceleration sensor is used to identify the motion state of the sliding door 11; the stress sensor is used to identify the position of the sliding door 11; and the deceleration module is installed on the track 12 on the side of the sliding door 11 adjacent to the door frame 10. The microprocessor acquires the motion state information and position information of the sliding door 11, and sends a deceleration command to the deceleration module based on the motion state information and position information. The deceleration module starts according to the deceleration command to stop the sliding door 11 in the closed state.
[0037] The microprocessor can be composed of a single-chip microcomputer or other microprocessor. It can acquire data, organize data, and output processing results with simple settings. In this embodiment, the microprocessor is electrically connected to the accelerometer, stress sensor, and deceleration module via wired or wireless means. It can acquire the motion state information of the sliding door 11 identified by the accelerometer and the position information of the sliding door 11 identified by the stress sensor, and output a deceleration command to the deceleration module based on the motion state information and position information. The deceleration module acquires the deceleration command and starts based on the deceleration command. When the sliding door 11 is transported to the deceleration module, the deceleration module can decelerate the sliding door 11 and stop it in the closed state. This can avoid the sliding door 11 from impacting and rebounding, thereby improving the user experience.
[0038] It should be noted that the door frame 10 can be composed of a door opening and a track 12. In this case, the track 12 is formed in the door opening. The door frame 10 can also be composed of a frame structure that is compatible with the door opening. When it is a frame structure, the track 12 is formed on the frame structure.
[0039] In one embodiment, the acceleration sensor is disposed on the sliding door 11 or on the door frame 10 adjacent to the side of the sliding door 11.
[0040] An accelerometer is installed on the sliding door 11 to obtain the acceleration information of the sliding door 11, that is, to obtain the motion state information of the sliding door 11. Alternatively, the accelerometer is installed on the door frame 10 adjacent to the sliding door 11 and positioned opposite to the sliding door 11, so that the acceleration information of the sliding door 11 can be obtained based on the distance between the accelerometer and the sliding door 11, that is, to obtain the motion state information of the sliding door 11.
[0041] In some embodiments, stress sensors are mounted on track 12 and are used to adapt to contact with sliding door 11 to obtain position information of sliding door 11.
[0042] Specifically, a stress sensor is pre-embedded in the track 12 and partially protrudes from the track 12. When the sliding door 11 moves on the track 12 and advances to the stress sensor, the sliding door 11 comes into contact with the stress sensor and generates stress, thus obtaining the position information of the sliding door 11.
[0043] Of course, in other embodiments, other structures can be used to obtain the position information of the sliding door 11, such as measuring the distance between the sliding door 11 and the door frame 10 by a distance sensor to obtain the position information of the sliding door 11.
[0044] In some embodiments, the deceleration module includes an elastic buffer 14, which is partially embedded in the track 12 and partially protrudes from the track 12 to fit the sliding door 11. The elastic buffer 14 can stop the sliding door 11 in the closed state by rotational friction.
[0045] Specifically, by setting a rotatable elastic buffer 14 in the track 12, and the rotation direction of the elastic buffer 14 is the same as the movement direction of the sliding door 11 but the rotation speed is less than the speed of the sliding door 11, the rotational friction between the elastic buffer 14 and the sliding door 11 can be used to reduce the speed of the sliding door 11 and ensure that the sliding door 11 is transported and stopped at a lower speed. In addition, based on the elastic deformation capability of the elastic buffer 14, the elastic buffer 14 can reduce the sliding interference to the sliding door 11 while ensuring its deceleration function, so that it can move smoothly.
[0046] In some embodiments, the reduction module also includes a motor, the output shaft of which is connected to the elastic buffer 14.
[0047] Specifically, the elastic buffer 14 can be connected to the motor in various ways. For example, the elastic buffer 14 is provided with an axially through hole, which is fixed to the output shaft of the motor. For example, the elastic buffer 14 is provided with an axially through hole and is fixed to the rotating shaft through the through hole, and the rotating shaft is connected to the output shaft of the motor for transmission.
[0048] In this embodiment, a motor connected to the elastic buffer 14 is provided, so the rotational speed of the elastic buffer 14 can be controlled by the motor. For example, when the acceleration of the sliding door 11 is large, the speed difference between the elastic buffer 14 and the sliding door 11 can be appropriately increased, and when the acceleration of the sliding door 11 is small, the speed difference between the elastic buffer 14 and the sliding door 11 can be appropriately decreased. This allows control of the rotational friction between the elastic buffer 14 and the sliding door 11, thereby achieving precise adjustment of the motion state of the sliding door 11.
[0049] In some embodiments, the axial cross-section of the elastic buffer 14 is gear-shaped, and the sliding door 11 is provided with a toothed groove 13, which is fitted to the elastic buffer 14. This increases the contact area between the elastic buffer 14 and the sliding door 11, thereby increasing the friction between them and improving their adjustment range, thus enabling them to handle sliding doors 11 with greater acceleration. In other words, this embodiment improves the reliability of the door closing device through the above-described configuration.
[0050] In some embodiments, the number of elastic buffers 14 is at least one, and when the number of elastic buffers 14 is multiple, the multiple elastic buffers 14 are arranged sequentially along the length direction of the track 12.
[0051] Specifically, when there are multiple elastic buffers 14, the multiple elastic buffers 14 are set in a coordinated manner.
[0052] This embodiment, by setting multiple elastic buffers 14, can further increase the friction between the door and the sliding door 11, thereby increasing its adjustment range and enabling it to handle sliding doors 11 with greater acceleration. In other words, this embodiment improves the reliability of the door closing device through the above-mentioned setup.
[0053] In some embodiments, the track 12 is located at the bottom of the sliding door 11, or at the top of the sliding door 11. Preferably, the track 12 is located at the bottom of the sliding door 11.
[0054] In some embodiments, the elastic buffer 14 contacts the side of the sliding door 11 to stop the sliding door 11 in the closed state. Alternatively, when the track 12 is located at the top of the sliding door 11, the elastic buffer 14 contacts the top surface of the sliding door 11 to stop the sliding door 11 in the closed state; or when the track 12 is located at the bottom of the sliding door 11, the elastic buffer 14 contacts the bottom surface of the sliding door 11 to stop the sliding door 11 in the closed state.
[0055] All of the above settings can achieve contact between the elastic buffer 14 and the sliding door 11, thereby ensuring the deceleration and stopping effect of the sliding door 11.
[0056] The second aspect of this utility model also provides a sliding door structure 100, including any of the closing devices described above. The structure of the closing device is as described in the above embodiments. Since the sliding door structure 100 in this embodiment includes the closing devices in all the above embodiments, it also has at least the beneficial effects of the above embodiments, which will not be described in detail here.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
