DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0019] The utility model discloses a sports medical chair electric push rod, including drive motor 1 and fixedly installed transmission mechanism 20 above drive motor 1, transmission mechanism 20 including fixedly connected in drive motor 1 output end turbine 4, with plastic helical gear 10 of meshing connection of turbine 4, set in the guide mechanism 30 inside for driving the cross - shift of slider nut pair 5 worm 14, and set in the fixed bearing 19 of worm 14 left end, slider nut pair 5 is connected in the middle region of worm 14 through the thread.

[0020] Transmission mechanism 20 right side fixedly installs guide mechanism 30, and guide mechanism 30 includes guide rod, sets up in the top sheet metal piece 8 of push rod whole one end, sets up in the tail bolt hole 16 of push rod whole other end, the push rod whole is fixed by tail bolt hole 16 and top sheet metal piece 8 head to tail.

[0021] In the embodiment, drive motor 1 is preferably overload protection motor, and the overload protection device built in drive motor 1 can rapidly react when detecting overload or abnormal condition, immediately stop the movement of push rod, effectively guarantee the safety of patients and medical staff, avoid the occurrence of unexpected situation, and also can prolong the service life of motor. Drive motor 1 is used as the power source of the whole device, is responsible for driving turbine 4 to drive worm 14, and then makes slider nut pair 5 perform telescopic movement.

[0022] Further, the turbine 4 in the transmission mechanism 20 is fixedly connected to the output end of the drive motor 1, the drive motor 1 transmits rotary power to the turbine 4, thereby driving the turbine 4 to rotate, the turbine 4 then drives the plastic helical gear 10 engaged therewith to rotate, the plastic helical gear 10 is fixedly connected to one end of the worm 14, so as to further drive the worm 14 to rotate, preferably, the plastic helical gear 10 is made of engineering plastic material, which can effectively reduce the noise generated when the metal is engaged.

[0023] Further, the fixed bearing 19 arranged at the leftmost end of the worm 14 mainly serves to support and fix the worm 14, ensuring that the worm 14 can stably rotate and transmit power, and the middle region of the worm 14 is threadedly connected to the slider nut pair 5.

[0024] Further, the slider nut pair 5 is provided with screw connections on both sides for firmly connecting the slider nut pair 5 to the corresponding structure of the electric push rod, ensuring that it does not loosen or shift during use. The screw connection provides a reliable fixing method, allowing the slider nut pair 5 to stably transmit power. The slider nut pair 5 is provided with a nut thread 3 connected to the worm 14 and a sliding plate in the middle. The nut thread 3 forms a threaded connection with the worm 14, and when the worm 14 rotates, the slider nut pair 5 moves linearly along the worm 14. The sliding plate is usually connected to the nut thread 3 or directly as part of the nut thread 3, ensuring that the slider nut pair 5 moves smoothly and without obstruction during linear motion. The slider nut pair 5 is provided with multiple support walls 6 on the side to strengthen the bearing capacity under the premise of reducing the size of the module. Thus, the overall extension mechanism of the electric push rod connected to the slider nut pair is changed from the traditional horizontal fixed end to the upper and lower sides, improving the installation space utilization rate of the push rod in the medical chair and enriching the application scenarios of the push rod.

[0025] Further, the guide rod in the guide mechanism 30 is composed of two parts, the left rail 11 and the right rail 13, which form a sliding block moving slide rail. The two ends are respectively supported and fixed by the fixed fastener 2 and the guide rod cap 12. The left rail 11 and the right rail 13 serve as the sliding rail for the slider nut pair 5 to move, providing a clear and stable movement path. When the electric push rod is working, the slider nut pair 5 moves along the sliding rail composed of the left rail and the right rail under the action of the driving force. This movement is smooth and continuous, ensuring that the electric push rod can work according to the predetermined speed and stroke. In addition, the left rail 11 and the right rail 13 also play a certain guiding and limiting role. They limit the deviation and shaking of the slider nut pair 5 during movement, thereby improving the accuracy and stability of the electric push rod.

[0026] Further, the control mechanism of the electric push rod is composed of an external controller and a sensor 9. The external controller is responsible for receiving the signals transmitted by the sensor 9 and accurately controlling the operation of the drive motor according to the pre-set program. The sensor 9 is arranged in the inner wall of the left rail 11 of the guide rod. It controls the stroke by triggering the sensor when the slider nut pair 5 reaches the limit of displacement, and is used to detect the position and motion state of the push rod in real time, providing an important basis for the decision of the controller.

[0027] The specific working principle is as follows: the sensor 9 triggers a signal by monitoring the limit displacement of the slider nut pair 5. When the slider nut pair 5 moves to the preset limit position, the sensor 9 captures the displacement and generates a corresponding signal, at which time the external controller continuously receives the signals from the sensor 9, which contain the current position and motion state information of the push rod. The controller processes these signals according to the preset program. The preset program can include a series of control algorithms and logical judgments for determining how the drive motor should operate. Based on the results of signal processing, the external controller will issue instructions to the drive motor 1 to precisely control its operation. These instructions can include starting, stopping, accelerating, decelerating, etc.

[0028] In use, the user can control the operation of the medical exercise chair electric push rod through the controller. When the drive motor 1 starts, it drives the worm 14 to rotate. Since the worm 14 is in threaded engagement with the nut thread 3 in the slider nut pair 5, when the worm 14 rotates, the slider nut pair 5 will move linearly along the worm 14. Thus, the lifting, pushing and pulling movements of the medical chair are achieved.

[0029] The medical exercise chair electric push rod of the utility model realizes the automatic adjustment of the medical exercise chair through the cooperation of the electric drive and control mechanism, specifically adopts the sensor and the transmission mechanism, ensures the accurate control of the movement of the push rod, can accurately meet the individualized rehabilitation needs of different patients, provides a strong guarantee for the improvement of the rehabilitation effect, and secondly is equipped with an overload protection motor, which can quickly respond when overload or abnormal conditions are detected, immediately stops the movement of the push rod, effectively guarantees the safety of patients and medical staff, and greatly reduces the work burden of medical staff, while significantly improving the adjustment efficiency.

[0030] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
