DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiment is one embodiment of the present application, not all embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] Unless otherwise defined, technical or scientific terms used in this application should have the common meanings understood by persons having ordinary skills in the field to which this application belongs.

[0020] This embodiment provides a biological sample storage device, Figure 1 is a schematic diagram of a biological sample storage device according to some embodiments of the present application with the box body hidden; Figure 2 yes Figure 1 a side view of the structure shown; Figure 3 yes Figure 1 The structure shown is a schematic diagram after the connecting plate and the limiting device are hidden; Figure 4 yes Figure 3 a side view of the structure shown; Figure 5 is a schematic diagram of a door of a biological sample storage device according to some embodiments of the present application; Figure 6 yes Figure 5 Front view of the structure shown.

[0021] The biological sample storage device includes: a box body, which defines a storage cavity for storing biological samples, and the storage cavity has an entrance and exit for the biological samples to enter and exit the storage cavity; a door body 100, which is arranged at the entrance and exit and is used to open and close the entrance and exit; a driving component connected to the door body 100, and is used to first drive the door body 100 to move to a side away from the storage cavity when opening the door body 100, and then drive the door body 100 to move downward, and is used to first drive the door body 100 to move upward, and then drive the door body 100 to move to a side close to the storage cavity when closing the door body 100.

[0022] When the door body 100 of this biological sample storage device is opened, the door body 100 is first moved to the side away from the accommodating chamber, and then the door body 100 is moved downward. When the door body 100 is closed, the door body 100 is first moved upward, and then the door body 100 is moved to the side close to the accommodating chamber. Therefore, not much space needs to be reserved above the entrance and exit, so that it is convenient to perform maintenance and other operations on the door body 100 when the door is opened, and the user can conveniently perform these operations without standing in a high place.

[0023] The biological sample storage device may further include a cover shell defining a shell cavity, wherein the cover shell covers the door body 100 and the drive assembly so that the shell cavity accommodates the door body 100 and the drive assembly, and the top of the cover shell has an opening for the biological sample to enter and exit the shell cavity.

[0024] Since cold air will naturally sink, this top opening setting reduces the degree of outward diffusion of internal cold air and reduces the degree of inward diffusion of external hot air, which is beneficial to the storage of biological samples. This top opening method also reduces the degree of internal frost.

[0025] Furthermore, the arrangement of the drive assembly means that the top of the housing does not need to be too high, which facilitates the docking device or the user to perform pick-and-place operations at the top opening.

[0026] The driving assembly includes a guide rail plate, which is installed at the inlet and outlet, and is provided with a guide groove, wherein the guide groove has a first section extending in the vertical direction, and the upper end of the first section and the area corresponding to the upper end of the inlet and outlet are connected to the second section of the guide groove, and the middle part of the first section and the area corresponding to the lower end of the inlet and outlet are connected to the third section of the guide groove, and the second section and the third section extend in the inner and outer directions of the accommodating cavity; the driving device 300 is installed in the box body, and is used to drive the door body 100 to move along the guide groove. The setting of the guide rail plate enables the door body 100 to be better limited.

[0027] The door body 100 may include: a door panel 110, wherein a fixing plate 170 is fixed to the side of the door panel 110 corresponding to the guide rail plate; a first sliding member, including a first sliding portion 120 fixed to the fixing plate 170, and including a second sliding portion 130 rotatably connected to the first sliding portion 120, wherein the first sliding portion 120 and the second sliding portion 130 are arranged in the guide groove.

[0028] In some other embodiments, a manipulator may be used to grab the door body 100 to move the door body 100. In other embodiments, a dual-axis moving mechanism may be used to drive the door body 100 to move in two directions. In this embodiment, one motor can be used to move the door body 100 in two directions, which occupies less space and has a lower cost than a manipulator.

[0029] Preferably, the door body 100 further comprises: a second sliding member, comprising a third sliding portion 140 fixed to the fixing plate 170, and comprising a fourth sliding portion 150 rotatably connected to the third sliding portion 140, wherein the third sliding portion 140 and the fourth sliding portion 150 are arranged in the guide groove. The arrangement of the second sliding member makes the door body 100 open and close more smoothly, and has better sealing when closed. It can be understood that the first sliding member and the second sliding member can be arranged along the vertical direction.

[0030] In some embodiments, the second sliding portion 130 and the fourth sliding portion 150 are fixedly connected via a connecting plate 160, and the connecting plate 160 is connected to the driving device 300, so as to move vertically under the drive of the driving device 300 to drive the second sliding portion 130 and the fourth sliding portion 150 to move along the first section.

[0031] In some embodiments, the output shaft of the driving device 300 is connected to the driving wheel 310, the guide plate is installed with a driven wheel 320, a transmission belt 330 is connected between the driving wheel 310 and the driven wheel 320, and the transmission belt 330 is fixed to the connecting plate 160. Thus, the position of the driving device 300 is conveniently arranged.

[0032] The connection plate 160 is connected to a limiting device 400, and the limiting device 400 is slidably connected to the box body via a vertical slide rail. Specifically, the limiting device 400 can be a slider, and the slider can slide via the slide rail.

[0033] The guide rail plates may be disposed on both lateral sides of the inlet and outlet. It is understandable that the first sliding member, the second sliding member, etc. may be multiple, and the first sliding member, the second sliding member, etc. may be disposed on both lateral sides of the inlet and outlet. Thus, the door body 100 is opened and closed more smoothly, and has better sealing performance when closed.

[0034] The biological sample storage device further includes a connecting rod 500, which connects the connecting plates 160 on both sides of the inlet and outlet, so that the vertical movement of one connecting plate 160 is transmitted to the other connecting plate 160. Thus, one driving device 300 can drive both sides to move at the same time.

[0035] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.

[0036] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. The protection scope of the present application shall be based on the protection scope of the claims.
