[0042] In addition, the terms "first", "second", and the like, if any, are used herein for descriptive purposes only and should not be construed as indicating or implying relative importance or implicating the number of indicated technical features. Thus, a feature defined with "first" or "second" can include at least one of the features explicitly or implicitly. In the description of the present application, the term "plurality" means at least two, for example, two, three, etc., unless otherwise explicitly specified and limited.

[0043] In the present application, unless otherwise explicitly specified and limited, if the terms "mounting", "connecting", "connecting", "fixing" and the like appear, these terms should be interpreted broadly. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0044] In the present application, unless otherwise explicitly specified and limited, if the first feature is described as "on" or "under" the second feature, etc., it can mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be the first feature directly above or obliquely above the second feature, or it can only mean that the first feature is higher than the second feature in horizontal height. The first feature "below", "below" and "below" the second feature can be the first feature directly below or obliquely below the second feature, or it can only mean that the first feature is lower than the second feature in horizontal height.

[0045] It should be noted that if an element is referred to as "fixed to" or "disposed to" another element, it can be directly on another element or there can be a middle element. If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element. If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in the present application are only for illustrative purposes and do not represent the only implementation.

[0046] Please refer to Figures 1 to 4An embodiment of the present application provides a sample drawer device 100, which is opened and closed to place or take out a sample rack 102 in the sample drawer device 100, and the sample rack 102 is used to place a sample tube. When the sample drawer device 100 is applied to a medical device, the sample rack 102 in the sample drawer device 100 can be transported in the medical device, and samples in the sample tube (not shown) on the sample rack 102 are processed. The sample drawer device 100 includes a drawer support 110, a drawer body 120, and a driving assembly 130. The drawer body 120 is slidably arranged in the drawer support 110 and has an open position and a closed position. The drawer body 120 includes a loading portion 122 and a driven portion 124, and the driven portion 124 is arranged on the loading portion 122. The driving assembly 130 is arranged on the drawer support 110, and the driving assembly 130 includes a driving member 131 and a transmission mechanism 132, the driving member 131 is connected with the transmission mechanism 132, the transmission mechanism 132 includes a transmission member 133, the transmission member 133 is provided with a driving portion 134, and the driving portion 134 is separably matched with the driven portion 124. The driving member 131 is used to drive the transmission member 133 to rotate forward or reversely, so that the driving portion 134 pushes the driven portion 124 to move, to drive the drawer body 120 to move to the open position or the closed position.

[0047] By arranging the driven portion 124 on the loading portion 122 of the drawer body 120 and arranging the driving portion 134 on the transmission member 133 of the driving assembly 130, the driving portion 134 is separably matched with the driven portion 124. When the driving member 131 of the driving assembly 130 drives the transmission member 133 to rotate forward, the driving portion 134 pushes the driven portion 124 to move along the forward direction, so that the drawer body 120 is opened to the open position. In this process, the user can simultaneously pull out the drawer body 120 outward to achieve rapid pulling out. When the driving member 131 of the driving assembly 130 drives the transmission member 133 to rotate reversely, the driving portion 134 pushes the driven portion 124 to move along the reverse direction, so that the drawer body 120 is closed to the closed position. In this process, the user can simultaneously push the drawer body 120 inward to achieve rapid pushing in. Therefore, on the basis of realizing automatic opening and closing of the drawer body 120, the operator can quickly pull out or push in the drawer body 120 for manual intervention, and the automatic opening and closing and the manual opening and closing are combined, automatic and manual integration and flexible conversion are realized, the automation and intelligence are realized, the requirement of convenient manual operation is met, and the normal operation of the equipment is not affected.

[0048] It should be noted that the "open position" herein refers to the position when the drawer body 120 is fully opened, i.e. the maximum limit position when the drawer body 120 is pulled outwards. The "closed position" refers to the position when the drawer body 120 is fully closed, i.e. the maximum limit position when the drawer body 120 is pushed inwards. The "forward direction" herein is not limited to the opening direction of the drawer body 120 as listed above, but can also be the closing direction of the drawer body 120, and the "reverse direction" is the opening direction of the drawer body 120 accordingly.

[0049] In the embodiment, the transmission member 133 has a rotation plane, which is arranged towards the bottom of the loading portion 122, so that the rotation plane is horizontally arranged, i.e. the driving portion 134 rotates in the horizontal plane. The transmission member 133 comprises a transmission body, and the driving portion 134 extends outwards from the outer side of the transmission body. The driven portion 124 is arranged at the bottom of the loading portion 122 and corresponds to the driving portion 134, so that the driven portion 124 can be driven by cooperating with the driving portion 134 within the activity range of the driving portion 134. By horizontally arranging the transmission member 133, the cooperation between the driving portion 134 and the driven portion 124 is realized in the horizontal direction, which is beneficial to reduce the height of the sample drawer device 100. It can be understood that in other embodiments, the transmission member 133 can be vertically arranged, so that the rotation plane is perpendicular to the bottom of the loading portion 122, and the driven portion 124 can also be arranged at the side of the loading portion 122.

[0050] The transmission member 133 is a belt transmission member or a strip transmission member, and the driving portion 134 can be deformed. When the drawer body 120 is closed, if the resistance is too large, for example, hand clamping, the transmission member 133 and the driving portion 134 can pass through the driven portion 124 by deformation, so as to realize movement disengagement, prevent the driving portion 134 from continuously pushing the driven portion 124 to move, and achieve the functions of collision protection and hand clamping protection. In the embodiment, the transmission member 133 is a synchronous belt, which is an integral molding structure, i.e. the transmission body and the driving portion 134 are integrally molded. In other embodiments, the transmission member 133 can also be a chain.

[0051] Please refer to Figure 5 and Figure 6In the embodiment, the driving member 131 is a motor, the transmission mechanism 132 further comprises a driving wheel 135 and a driven wheel 136, the driving wheel 135 and the driven wheel 136 are rotatably arranged at the bottom of the drawer support 110, and a synchronous belt is sleeved on the driving wheel 135 and the driven wheel 136. The driving wheel 135 serves as an input end of the transmission mechanism 132, which can be directly or indirectly connected with the motor. The motor drives the driving wheel 135 to rotate, and drives the synchronous belt to rotate. The motor has an encoder, which can determine whether there is a lock-up or a collision when the drawer is closed or opened. When the lock-up or the collision occurs, the motor stops working, thereby achieving the effects of collision protection and anti-pinch protection. Therefore, the encoder of the motor is combined with the deformable transmission member 133 and the driving portion 134 thereof, thereby achieving the functions of double collision protection and anti-pinch protection.

[0052] In order to better control the rotation speed of the transmission member 133, the driving assembly 130 further comprises a speed reduction mechanism 137 connected between the motor and the input end of the transmission mechanism 132, so as to better control the opening or closing speed of the drawer body 120, and prevent the drawer body 120 from being opened or closed too fast to cause a collision. In the embodiment, the speed reduction mechanism 137 is provided corresponding to the transmission mechanism 132, and specifically is a wheel belt type speed reduction mechanism. In other embodiments, the speed reduction mechanism 137 can adopt a gear type speed reduction mechanism.

[0053] Please refer to Figure 7 and Figure 8 , and Figure 4 In the embodiment, the sample drawer device 100 further comprises an opening sensor 140, a closing sensor 141 and a controller (not shown), the opening sensor 140 is arranged on the drawer support 110 and is used to detect whether the drawer body 120 is located at an open position. The closing sensor 141 is arranged on the drawer support 110 or the driving assembly 130 and is used to detect whether the drawer body 120 is located at a closed position. The controller is electrically connected with the driving member 131, the opening sensor 140 and the closing sensor 141 respectively, and is used to control the driving member 131 according to the detection signals of the opening sensor 140 or the closing sensor 141. It should be noted that the controller can be separately arranged for the sample drawer device 100, or can be a controller of a medical equipment, which can control the sample drawer device 100 and other devices of the medical equipment.

[0054] In the process of opening the drawer body 120, the drawer body 120 can be moved to the open position under the action of the transmission member 133 or manual action, when the opening sensor 140 detects that the drawer body 120 is located at the open position, the drawer body 120 cannot continue to open, and the driving member 131 stops driving the transmission member 133 to move; the drawer body 120 can be moved to other positions under the action of the transmission member 133 or manual action, while the opening sensor 140 detects that the drawer body 120 is not at the open position, the driving member 131 drives the transmission member 133 to rotate forward, the driving part 134 pushes the driven part 124 to continue to move in the forward direction, until the opening sensor 140 detects that the drawer body 120 is located at the open position. In the process of closing the drawer body 120, the drawer body 120 can be moved to the closed position under the action of the transmission member 133 or manual action, when the closing sensor 141 detects that the drawer body 120 is located at the closed position, the drawer body 120 cannot continue to close, and the driving member 131 stops driving the transmission member 133 to move; the drawer body 120 can be moved to other positions under the action of the transmission member 133 or manual action, while the closing sensor 141 detects that the drawer body 120 is not at the closed position, at this time, the driving member 131 drives the transmission member 133 to rotate reversely, the driving part 134 pushes the driven part 124 to continue to move in the reverse direction, until the closing sensor 141 detects that the drawer body 120 is located at the closed position. Therefore, by setting the opening sensor 140 and the closing sensor 141 to sense whether the drawer body 120 is in place, whether in manual intervention or in automatic opening and closing, the drawer body 120 can be ensured to be moved to the open position or the closed position.

[0055] In order to improve the opening and closing efficiency of the drawer body 120, the sample drawer device 100 further comprises an initial sensor 142, which is arranged on the driving assembly 130 and is used for detecting whether the driving part 134 is located at the initial position. The controller is electrically connected with the initial sensor 142, and is used for controlling the driving member 131 according to the detection signal of the initial sensor 142. When the initial sensor 142 detects that the driving part 134 is located at the initial position, the driving part 134 has completed resetting, and the controller controls the driving member 131 to stop working; when the initial sensor 142 detects that the driving part 134 is not moved to the initial position, the controller controls the driving member 131 to continue to drive the transmission member 133 to move, until the driving part 134 is detected by the initial sensor 142. By controlling the driving part 134 to move to the initial position, the stroke of opening or closing the drawer body 120 is shortened, which is beneficial to improve the opening and closing efficiency of the drawer body 120.

[0056] In combination with the above, in the present embodiment, the working principle of the sample drawer device 100 is as follows:

[0057] In the opening process of the drawer body 120, the motor drives the synchronous belt of the driving assembly 130 to rotate forward. After the driving part 134 of the synchronous belt contacts the driven part 124 of the drawer body 120, the drawer body 120 is pushed open in the forward direction. After the drawer body 120 moves to the open position, the opening sensor 140 detects the drawer body 120 and gives a detection signal to the controller, and the controller controls the synchronous belt of the driving assembly 130 to stop rotating. In the automatic opening process, the opening can be accelerated manually according to the requirement (the opening can be to the position or a certain distance). If the manual opening is not to the open position and is not sensed by the opening sensor 140, the driving part 134 of the synchronous belt continues to push the drawer body 120 in the forward direction. When the opening sensor 140 senses that the drawer body 120 moves to the open position, the motor drives the synchronous belt to rotate reversely, until the driving part 134 is detected by the initial sensor 142, and the reset of the driving part 134 is completed, and the motor stops driving. If the manual opening is to the open position and is detected by the opening sensor 140, the motor drives the synchronous belt to rotate reversely immediately, until the driving part 134 is detected by the initial sensor 142, and the reset of the driving part 134 is completed, and the motor stops driving.

[0058] In the closing process of the drawer body 120, the motor drives the synchronous belt of the driving assembly 130 to rotate reversely. After the driving part 134 of the synchronous belt contacts the driven part 124 of the drawer body 120, the drawer body 120 is pushed closed in the reverse direction. After the drawer body 120 moves to the closed position, the closing sensor 141 detects the drawer body 120 and gives a detection signal to the controller, and the controller controls the synchronous belt of the driving assembly 130 to stop rotating. In the automatic closing process, the closing can be accelerated manually according to the requirement (the closing can be to the position or a certain distance). If the manual closing is not to the closed position and is not sensed by the closing sensor 141, the driving part 134 of the synchronous belt continues to push the drawer body 120 in the reverse direction. When the closing sensor 141 senses that the drawer body 120 moves to the closed position, the motor drives the synchronous belt to rotate forward, until the driving part 134 is detected by the initial sensor 142, and the reset of the driving part 134 is completed, and the motor stops driving. If the manual closing is to the closed position and is detected by the closing sensor 141, the motor drives the synchronous belt to rotate forward immediately, until the driving part 134 is detected by the initial sensor 142, and the reset of the driving part 134 is completed, and the motor stops driving.

[0059] The sample drawer device 100 further comprises an electromagnetic structure 143 arranged on the drawer support 110 and used for electromagnetically attracting the drawer body 120. A controller is electrically connected with the electromagnetic structure 143 and used for controlling the electromagnetic structure 143 to work according to a detection signal of the closing sensor 141. When the closing sensor 141 senses that the drawer body 120 moves to the closed position, the controller controls the electromagnetic structure 143 to start according to the sensing signal, and the drawer body 120 is attracted to realize self-locking, thereby preventing the drawer body 120 from being automatically opened due to external force when the drawer body 120 is closed.

[0060] In the embodiment, the electromagnetic structure 143 is arranged at the outer end of the drawer support 110 and used for magnetically attracting the outer end of the iron sheet of the drawer body 120. The electromagnetic structure 143 comprises an electromagnet which can generate a magnetic field when powered on and magnetically attract the iron sheet.

[0061] Please refer to Figure 9 and Figure 10 , and Figure 3 In the embodiment, the other side of the bottom of the drawer body 120 is provided with a detection portion 126 corresponding to the driven portion 124 and close to the inner end of the drawer body 120. The opening sensor 140 is arranged on the bottom of the drawer support 110 and close to the outer end of the drawer support 110. The closing sensor 141 is arranged on the driving assembly 130 and corresponding to the bottom of the inner end of the drawer support 110. The initial sensor 142 is arranged on the driving assembly 130 and between the driving wheel 135 and the driven wheel 136. The detection portion 126 cooperates with the opening sensor 140 and the closing sensor 141. When the drawer body 120 moves to the open position, the opening sensor 140 can sense the detection portion 126. When the drawer body 120 moves to the closed position, the closing sensor 141 can sense the detection portion 126. When the driving portion 134 moves to the initial position, the initial sensor 142 can detect the driving portion 134. The opening sensor 140, the closing sensor 141 and the initial sensor 142 can be, but are not limited to, Hall sensors or infrared sensors.

[0062] In the embodiment, the drawer support 110 is provided with slide rails 111 on opposite sides, and the slide rails 111 are provided with buffer mechanisms 112 corresponding to the inner ends of the drawer support 110 and used for buffering the opening and closing of the drawer body 120. The buffer mechanisms 112 can buffer the opening and closing of the drawer body 120, so that the sample tubes in the sample rack 102 are not vibrated violently when the drawer body 120 moves to the open position or the closed position.

[0063] In the embodiment, the buffering mechanism 112 comprises a buffering body 113 and an elastic member 114, the elastic member 114 is connected between the buffering body 113 and the inner end of the slide rail 111, when the drawer body 120 is opened, the buffering body 113 is limited in the slide rail 111, and the elastic member 114 is in a tension state, with the drawer body 120 being pushed in, the matching structure of the drawer body 120 is connected with the buffering body 113, and the buffering body 113 is pushed to move inward, so that the buffering body 113 is released from the limitation, the elastic member 114 is contracted to pull the drawer body 120 into the drawer support 110, and the closing of the drawer body 120 is buffered; when the drawer body 120 is opened, with the drawer body 120 being opened, the matching structure of the drawer body 120 drives the buffering body 113 to move outward, and the elastic member 114 is stretched until the buffering body 113 is limited, at this time, the elastic member 114 is in a tension state, the matching structure of the drawer body 120 is separated from the buffering body 113, and the opening of the drawer body 120 is buffered.
