The test device is a device capable of providing a specific storage space, and can set environmental parameters such as temperature, humidity and the like of the storage space to provide a required simulation environment. In the battery production process, in order to perform performance test on the battery cells, a part of the battery cells are usually stored as a test sample in a test device. The testing equipment comprises a box body and a box door, wherein the box door can open and close a box door opening of the box body. When the door is opened/closed, the door is easy to be hard-bumped with the box body, so that the service life of the testing equipment is reduced.

In order to improve the service life of the test equipment, a buffer structure for consuming the impact force of the box door can be arranged between the box body and the box door. Specifically, the buffer structure can be arranged at the closing position of the box body when the box door is closed and at the maximum opening and closing position of the box body when the box door is opened, so that the impact degree of the box door between the opening and closing box door opening and the box body is reduced.

Based on this, in order to improve the service life of the test equipment, the embodiment of the application designs the test equipment, which comprises a box body, a box door, a door opening buffer structure and a door closing buffer structure, wherein the door opening buffer structure is used for buffering and connecting the box door with the box body when the box door is positioned at a position for opening a box door opening, the door closing buffer structure is used for buffering and connecting the box door with the box body when the box door is positioned at a position for closing the box door opening, and the door opening buffer structure and the door closing buffer structure can both dissipate the impact force of the box door and the box body when in contact, so that the damage degree of the box door and the box body is reduced, and the service life of the test equipment is improved.

It should be noted that those skilled in the art may also adopt some other comparison schemes to solve the above technical problems. As an example solution, the same buffer mechanism may be directly disposed between the door and the case, where the buffer mechanism may play a role in buffering and decelerating when the door is closed and opened, and the example solution has a problem that the door still receives the buffer mechanism in the middle process of opening and closing the door, and requires more energy to support the movement of the door.

Compared with the test equipment designed by the embodiment of the application, the door opening buffer structure and the door closing buffer structure only play a role in buffering and decelerating when the door reaches the position for closing the door opening of the box and the position for completely opening the door opening of the box, do not play a role in the middle process of the door, and can reduce the energy consumption required by the door in the moving process.

The test equipment provided by the embodiment of the application is mainly used for storing the sample to be tested and providing a certain storage environment for the sample to be tested. The sample to be tested can be applied to a battery cell, a battery module, a battery pack and the like, but can also be used for testing stored materials.

Wherein each battery cell may be a secondary battery or a primary battery; but not limited to, lithium sulfur batteries, sodium ion batteries, or magnesium ion batteries. The battery cells may be cylindrical, flat, rectangular, or otherwise shaped.

The test equipment provided by the embodiment of the application is described in detail below.

FIG. 1 is a schematic diagram of a test apparatus 100 of one or more embodiments. Fig. 2 is another azimuthal view of the test apparatus 100 shown in fig. 1. Fig. 3 is a schematic diagram of the structure of the case 10 of the test apparatus 100 shown in fig. 1.

Referring to fig. 1 to 3, according to one or more embodiments of the present application, a test apparatus 100 according to an embodiment of the present application includes a case 10, a door 20, a door opening buffer structure 30, and a door closing buffer structure 40. The case 10 has a door opening K, and the door 20 is rotatably provided to the case 10 to open and close the door opening K. The door opening buffer structure 30 is provided to one of the case 10 and the door 20, and is configured to buffer contact with the other of the case 10 and the door 20 when the door 20 is located at a position where the door opening K is opened. The door closing buffer structure 40 is provided to one of the case 10 and the door 20, and is configured to buffer contact with the other of the case 10 and the door 20 when the door 20 is located at a position to close the door opening K.

The case 10 is a main structure for providing a storage space for a sample to be tested, and a test cavity R is formed inside the case 10, and the test cavity R is the storage space of the test apparatus 100. The housing 10 generally has a high strength to effectively protect the sample to be tested located in the test chamber R. The case 10 may be made of, but not limited to, aluminum alloy, stainless steel, or the like. The case 10 may have a regular shape such as a rectangular parallelepiped, a hexagonal prism, a cylinder, or the like.

The box 10 is provided with a box door opening K communicated with the inside and the outside of the testing cavity R, and a sample to be tested can enter and exit the testing cavity R through the box door opening K. The door 20 is rotatably provided on the case 10, and can open and close the door opening K during rotation. The door 20 is generally made of the same material as the case 10, and is generally rotatably connected to the case by an adapter 21, and the adapter 21 may be, but is not limited to, a hinge, a rotating shaft, or the like. Generally, the door 20 is rotatably provided on the cabinet 10 along a rotation axis O parallel to the height direction Z of the cabinet 10. Further, the door 20 is rotatably coupled to one side of the cabinet 10 in the width direction X (vertical height direction Z) to maximally open the door opening K opened at least one end of the door 20 in the length direction Y. Typically, a holder (not shown) may be provided within the test chamber R for placing a sample to be tested.

The door 20 has two extreme positions, a first extreme position and a second extreme position, respectively, during rotation. The first limit position in which the door 20 completely closes the door opening K is understood as "the position in which the door 20 closes the door opening K" as referred to in the embodiment of the present application. The second limit position is the position where the door 20 is located to maximally open the door K, that is, the "position where the door 20 opens the door K" in the embodiment of the present application. When the door 20 rotates between the two extreme positions, the door 20 is liable to collide with the door 10 by the action of the rotational inertia force, and the door 20 and the door 10 are liable to be damaged by the collision.

The buffer structure is a structure capable of reducing the impact velocity, which is capable of gradually reducing the relative motion velocity between two objects having a relative motion and consuming the impact force existing due to the relative motion velocity. The buffer structure is a first object and a second object which are usually used for approaching each other, the buffer structure can be arranged on the first object, when the first object moves towards the second object at a certain speed, and when the first object and the second object approach each other, the buffer structure on the first object is firstly contacted with the second object, and the buffer structure can consume the impact force of the first object to enable the movement speed of the first object to be slowed down until the first object is completely stopped. Under the effect of the buffer structure, the impact degree of the first object on the second object can be reduced. The cushioning structure may be, but is not limited to, a rubber cushioning structure, a silicone cushioning structure, an elastic cushioning structure, a damping cushioning structure, and the like.

The door opening buffer structure 30 and the door closing buffer structure 40 are both buffer structures. The door opening buffer structure 30 buffers and connects the door 20 and the case 10 when the door 20 reaches the second limit position, and consumes the impact force between the two, thereby slowing down the speed of the door 20 approaching the case 10, and reducing the collision degree of the door 20 and the case until the door 20 reaches the second limit position. The door closing buffer structure 40 buffers and connects the door 20 and the case 10 when the door 20 is about to reach the first limit position, and consumes the impact force between the two, slows down the speed of the door 20 approaching the case 10, and reduces the collision degree of the door 20 and the case 10 until the door 20 reaches the first limit position.

It is understood that the switch cushioning structure is disposed on one of the cabinet 10 and the door 20 and is in cushioning contact with the other at the second limit position. The door closing buffer structure 40 is disposed at one of the case 10 and the door 20, and is in buffer contact with the other at a first limit position. Buffer contact means that the buffer structure is in contact with the other and can slow down and reduce the impact degree between the buffer structure and the other.

The door opening buffer structure 30 and the door closing buffer structure 40 may be provided in plurality. The plurality of door opening buffer structures 30 may be disposed on the same one of the case 10 and the door 20, or a part of the door opening buffer structures 30 may be disposed on the case 10, and a part of the door opening buffer structures 30 may be disposed on the door 20. Of course, when the door 20 reaches the second limit position, the door opening buffer structure 30 on the door 20 may be in buffer contact with the door opening buffer structure 30 on the box 10 when the box 10 and the door 20 are both provided with the door opening buffer structure 30.

Similarly, the plurality of door closing buffer structures 40 may be disposed on the same one of the case 10 and the door 20, or a part of the door closing buffer structures 40 may be disposed on the case 10, and a part of the door closing buffer structures 40 may be disposed on the door 20. Of course, when the door 20 reaches the first limit position, the door closing buffer structure 40 on the door 20 may be in buffer contact with the door closing buffer structure 40 on the box 10 when the box 10 and the door 20 are both provided with the door closing buffer structure 40.

According to the testing equipment 100, when the box door 20 is about to reach two limit positions, the box door 20 and the box body 10 can be connected in a buffering manner through the door closing buffer structure 40/the door opening buffer structure 30, the impact speed of the box door 20 to the box body 10 is slowed down by utilizing the door closing buffer structure 40/the door opening buffer structure 30, the impact force of the box door 20 to the box body 10 is reduced, the collision probability of the box door 20 and the box body 10 is reduced, the service lives of the box door 20 and the box body 10 can be greatly prolonged, and the service life of the testing equipment 100 is prolonged.

Meanwhile, in the technical solution of the embodiment of the present application, the door closing buffer structure 40 and the door opening buffer structure 30 are separately arranged at two limit positions corresponding to the door 20, and the door closing buffer structure 40 and the door opening buffer structure 30 only play a role in buffering when the door 20 is about to reach two limit positions, and in most of the strokes of closing the door 20 and opening the door K, the door closing buffer structure 40 and the door opening buffer structure 30 do not affect the strokes thereof, so that the driving force loss (such as manpower loss) for driving the door 20 to open/close the door K can be reduced, which is helpful for energy saving.

In some embodiments, referring to fig. 3, the case 10 has a test chamber R, a case door opening K communicates with the test chamber R, and at least one of the door opening buffer structure 30 and the door closing buffer structure 40 is located outside the range of the test chamber R.

As noted above, the test chamber R is located inside the housing 10, which communicates with the door K of the housing, and is generally provided internally with a rack for placing the sample to be tested. The test chamber R is used as a storage space of a sample to be tested, and the higher the space utilization rate of the test chamber R is, the larger the storage space of the sample to be tested is, and the better the test efficiency of the test device 100 is.

At least one of the door opening buffer structure 30 and the door closing buffer structure 40 is located outside the range of the test chamber R, i.e., does not occupy the space of the test chamber R. Specifically, both the door opening buffer structure 30 and the door closing buffer structure 40 are located outside the range of the test chamber R. Typically, the door opening buffer structure 30 and/or the door closing buffer structure 40 are provided on the outer wall of the cabinet 10 and/or the door 20.

At this time, the door opening buffer structure 30 and the door closing buffer structure 40 are located outside the range of the test chamber R, which is helpful to improve the space utilization of the test chamber R, and further improve the test efficiency of the test apparatus 100.

In some embodiments, referring to fig. 1 and 2, the door opening buffer structure 30 and the door closing buffer structure 40 are disposed on the case 10, and are disposed on opposite sides of the case 10 in a direction intersecting the rotation axis O of the door 20.

The rotation axis O of the door 20 is generally parallel to the height direction Z of the cabinet 10 and is located at one side of the cabinet 10 in the width direction X thereof, as shown in fig. 1. The direction intersecting the rotation axis O of the door 20 is substantially parallel to the width direction X of the cabinet 10.

At this time, the door opening buffer structure 30 and the door closing buffer structure 40 are both arranged on the box 10, so that the energy consumption of the box door 20 in the rotation process is not required to be consumed, and the door opening buffer structure 30 and the door closing buffer structure 40 are positioned on two opposite sides of the box 10, so that the door opening buffer structure is simple in structure, and the buffer effect of the door opening buffer structure 30 and the door closing buffer structure 40 on the box door 20 is easy to realize.

Fig. 8 is a schematic structural view of a damping cushion a22 of one or more embodiments.

In some embodiments, referring to fig. 6, 7 and 8, the buffer A2 includes a damping buffer a22, the damping buffer a22 has a fixed end D1 and a contact end D2, and the fixed end D1 is disposed on the mounting seat A1. The contact end D2 of the door opening buffer structure 30 contacts the case 10 or the door 20 when the door 20 is positioned at a position to open the door K. The contact end D2 of the door closing buffer structure 40 contacts the case 10 or the door 20 when the door 20 is at a position to close the door K.

The damping buffer a22 is a structure that absorbs or suppresses impulse by utilizing damping characteristics to thereby alleviate mechanical vibration and dissipate kinetic energy. The damping buffer a22 may be, but is not limited to, a hydraulic damping structure, a pneumatic damping structure. As for the specific structure of the damping buffer a22, reference may be made to a conventional arrangement in the art.

In some examples, referring to fig. 8, the damping buffer portion a22 includes a piston rod a22a and a cylinder a22b, where the piston rod a22a is telescopically disposed in the cylinder a22b, the piston rod a22a divides an internal space of the cylinder a22b into a first area and a second area, liquid or gas is filled in the first area, the piston rod a22a makes a buffer contact with the door 20 or the box 10, and during the buffer contact, the piston rod a22a retracts into the cylinder a22b, and continuously compresses a volume of the first area, and the compressed liquid and gas generate a blocking force to block retraction of the piston rod a, thereby reducing an operation speed of the door 20 and consuming an impact force of the door 20.

Further, the damping buffer portion a22 further includes an adjusting member a22c, where the adjusting member a22c is movably disposed on the cylinder a22b and defines a first area together with the piston rod a22a, and the adjusting member a22c can change the volume of the first area during moving, so as to adjust the pressure generated by the liquid or the gas in the first area. The adjustment member a22c may be, but is not limited to, a threaded member. Further, the damping buffer a22 further includes a fastener, which is a fastener

The fixed end D1 of the damping buffer a22 is fixedly disposed at one end of the mounting seat A1, and is fixed relative to the mounting seat A1, and the contact end D2 of the damping buffer a22 is one end contacting the case 10 or the door 20, and is movable relative to the mounting seat A1. In the above example, the contact end D2 of the damping buffer a22 is constituted by the free end of the piston rod a22a, and the fixed end D1 of the damping buffer a22 is constituted by the cylinder a22 b.

At this time, the buffer member A2 includes the damping buffer portion a22, and has a simple structure and reliable buffering.

In some embodiments, referring to fig. 6 and 7, the contact end D2 is provided with an engaging portion D22, and the engaging portion D22 engages with the box 10 or the box door 20 contacted by the contact end.

The engaging portion D22 can engage the case 10 or the door 20 when contacting the case 10 or the door 20. The engaging portion D22 may be a magnet engaging portion D22 or a soft rubber engaging portion D22. The magnet attraction portion D22 is in attraction connection with the case 10 or the door 20 by using the magnetic attraction effect of the magnet, and the case 10 or the door 20 may be made of metal. When the soft rubber suction portion D22 is in contact with the case 10 or the case door 20, the soft rubber suction portion D22 deforms under the pressing of the case 10 or the case door 20, and the air at the contact position between the soft rubber suction portion D22 and the case 10 or the case door 20 is exhausted to affect the small negative pressure, so that a certain suction effect can be generated between the case 10 or the case door 20 under the action of atmospheric pressure.

At this time, by using the engaging portion D22 on the contact end D2, the contact effect between the buffer member A2 and the door 20 or the case 10 can be enhanced, and the rebound degree when the door 20 reaches the limit position can be reduced, so that the door 20 moves more gently.

In some embodiments, referring to fig. 6, and referring to fig. 4, a mounting seat A1 of the door opening buffer structure 30 has a first side a11 and a second side a12, the first side a11 is fixedly connected with one of the box 10 or the box door 20, the second side a12 is obliquely arranged away from the other of the box 10 or the box door 20 relative to the first side a11, a buffer member A2 of the door opening buffer structure 30 is arranged on the second side a12, and a buffer direction F of the buffer member A2 is perpendicular to the second side a 12.

Taking the case 10 as an example, the mounting seat A1 is provided. The first side a11 of the mounting seat A1 and the case 10 may be welded, fastened, etc., and in the embodiment shown in fig. 6, the first side a11 of the mounting seat A1 is provided with a connection hole, and a fastener such as a bolt or a screw is fixedly disposed on the case 10 through the connection hole. The second side a12 of the mounting seat A1 and the buffer member A2 may be welded, interference connected or fastened, and in the embodiment shown in fig. 6, the second side a12 of the mounting seat A1 is provided with a mounting hole, and the buffer member A2 is mounted in the mounting hole.

The second side a12 is substantially planar. The first side a11 may also be, but is not limited to being, planar. It is understood that the buffer member A2 is retractable under the pressing of the door 20 or the case 10, and the buffer direction F of the buffer member A2 is the retraction direction thereof. When the shock absorber A2 includes the damping cushion a22, the cushion direction F of the damping cushion a22 may be the expansion and contraction direction of the piston rod a22 a.

When the mounting seat A1 is mounted on the cabinet 10, the second side a12 is disposed obliquely with respect to the first side a11 toward a direction away from the door 20. Since the buffering direction F of the buffer member A2 is perpendicular to the second side a12, as can be seen in fig. 6, when the buffer member A2 is in buffering contact with the door 20, the buffer member A2 is in substantially perpendicular contact with the door 20, that is, the buffering direction F of the buffer member A2 is substantially perpendicular to the door 20, so that the compression force received by the buffer member A2 is substantially along the buffering direction F of the door 20 in the process of approaching the case 10, which helps to protect the buffer member A2, and meanwhile, the buffering force of the buffer member A2 can also substantially act on the door 20, so that the buffering effect of the movement of the door 20 is better.

It is to be appreciated that when the mounting seat A1 is mounted on the door 20, the buffer member A2 also has the above effect, and the specific reasoning process is similar to that described above, and will not be repeated here.

In some embodiments, referring to fig. 4 and 5, the test apparatus 100 further includes a first contact structure 50 and/or a second contact structure 60. One of the first contact structure 50 and the door opening buffer structure 30 is disposed on the case 10, the other is disposed on the door 20, and when the door 20 is located at a position where the door opening K is opened, the first contact structure 50 is in buffer contact with the door opening buffer structure 30. One of the second contact structure 60 and the door closing buffer structure 40 is disposed on the case 10, the other is disposed on the door 20, and the first contact structure 50 is in buffer contact with the door closing buffer structure 40 when the door 20 is at a position to close the door opening K.

The first contact structure 50 is a structure that contacts the buffer A2 in the door opening buffer structure 30, and the second buffer structure is a structure that contacts the buffer A2 in the door closing buffer structure 40. Typically, the first contact structure 50 is fixedly attached, such as fastened, to the cabinet 10 or the door 20. Likewise, the second contact structure 60 is fixedly attached, such as fastened, to the cabinet 10 or the door 20.

The first contact structure 50 and the second contact structure 60 may be flexible structures or rigid structures. The flexible structure can be a rubber flexible block, a silica gel flexible block and the like, and can be flexibly contacted with the buffer A2, namely, can deform under the action of the buffer A2, so that impact force acting on the buffer A2 can be relieved. The rigid structure may be a metallic structure, a ceramic structure, a rigid plastic structure, which is capable of being in rigid contact with the buffer A2. When the first contact structure 50 and the second contact structure 60 are hard structures, they may be made of a material having good wear resistance.

At this time, the first contact structure 50 and the second contact structure 60 are respectively contacted with the door opening buffer structure 30 and the door closing buffer structure 40, so that the abrasion of the door opening buffer structure 30 and the door closing buffer structure 40 to the case 10 or the case door 20 can be reduced, and the service lives of the case 10 and the case door 20 can be prolonged.

In some embodiments, referring to fig. 7, the door closing buffer structure 40 includes a buffer member A2, the second contact structure 60 has a contact surface 61, when the door 20 is located at a position for closing the door K of the door, the buffer member A2 of the door closing buffer structure 40 is in buffer contact with the contact surface 61, and a buffer direction F of the buffer member A2 is perpendicular to the contact surface 61.

In the embodiment shown in fig. 7, the door closing buffer structure 40 is protruded on the case 10, the second contact structure 60 is protruded on the case door 20, and the contact surface 61 of the second contact structure 60 is substantially perpendicular to the case door 20. When the door 20 is positioned at a position to close the door opening K, the contact surface 61 of the second contact structure 60 faces the buffer member A2 of the door closing buffer structure 40 and can contact with the buffer end of the buffer member A2.

At this time, when the case body 10 closes the case door K, the buffering direction F of the buffering member A2 of the door closing buffering structure 40 is perpendicular to the contact surface 61, so that the compression force received by the buffering member A2 of the door closing buffering structure 40 is approximately along the buffering direction F thereof during the process of approaching the case body 10 by the case door 20, which helps to protect the buffering member A2, and meanwhile, the buffering force of the buffering member A2 can also basically act on the case door 20, so that the buffering effect of the movement of the case door 20 is better.

In some embodiments, referring to fig. 1 and 4, and referring to fig. 9, the test apparatus 100 further includes a telescopic driving mechanism 70, wherein one end of the telescopic driving mechanism 70 in a telescopic direction is fixed to the case 10, and the other end is rotatably disposed on the case door 20 around a direction parallel to a rotation axis of the case door 20. The telescopic driving mechanism 70 is configured to drive the door 20 to open and close the door opening K when telescopic in a direction intersecting the rotation axis O of the door 20.

The telescopic driving mechanism 70 is a mechanism capable of providing a linear driving force, and may be, but not limited to, a rack-and-pinion mechanism, an air cylinder 71 mechanism, a hydraulic cylinder mechanism, or the like. Generally, the telescopic driving mechanism 70 is provided on the same side of the case 10 as the door opening buffer structure 30.

Specifically, referring to fig. 9, the telescopic driving mechanism 70 includes a cylinder 71, a piston 72, and a fixing plate 73, wherein the cylinder 71 is fixed to the case 10, one end of the piston 72 is movably sleeved in the cylinder 71, and the fixing plate 73 is fixed to the case door 20 and is rotatably connected to the other end of the piston 72 in a direction parallel to the rotation axis O of the case door 20. The fixing plate 73 may be provided on the door 20 by fastening connection.

When the telescopic driving mechanism 70 is telescopic, the door 20 is pulled to rotate relative to the rotation axis O thereof to open and close the door 20 body. It will be appreciated that in the embodiment of fig. 4, when closing the door K of the box, the piston 72 of the telescopic drive mechanism 70 is extended and then retracted, and its cylinder 71 may be in a redundant state, i.e. not forced, during retraction.

At this time, the rotation of the door 20 is realized by the telescopic movement of the telescopic driving mechanism 70, and the structure is simple and easy to realize.

In some embodiments, referring to fig. 2 and 5, the test apparatus 100 further includes a latch 80 and a latch 90, one of the latch 80 and the latch 90 is disposed with the case 10, and the other is disposed with the door 20. The latch 80 and the catch 90 are configured to be engaged when the door 20 is closed at the door opening K, and to be separated when the door 20 is opened.

The locking notch and the fastener 90 have a combination state of being fastened together and a separated and disassembled state. In the assembled state, the latch 80 and the catch 90 can restrict the door 20 from opening the door opening K. In the disassembled state, the latch 80 and the catch 90 can allow the door 20 to open the door opening K.

The latch 80 has a latch, the fastener 90 has a latch tongue, the latch tongue is movably disposed relative to the case 10, and has a fastening position and a disassembling position in the moving process, when the door 20 closes the door opening K, the latch tongue is switched from the disassembling position to the fastening position and cooperates with the latch hook to limit the latch hook from being disengaged, thereby limiting the door 20 from opening the door opening K. When the door opening K needs to be opened, the lock tongue is switched to the disassembled position, and when the lock tongue is positioned at the disassembled position, the lock hook can be prevented from moving, so that the door 20 is allowed to rotate.

In other embodiments, the locking member 80 and the locking member 90 may also be engaged in other manners, which are not limited to the above embodiments, and those skilled in the art may perform conventional arrangements, so long as the locking of the door 20 and the case 10 can be achieved. For example, a concave hole is formed on the locking member 80, and a protrusion is formed on the buckling member 90, so that when the protrusion is inserted into the concave hole, the locking member 80 and the buckling member 90 are in a buckled combination state. When the protrusions are separated from the concave holes, the locking piece 80 and the buckling piece 90 are in a separated and disassembled state.

At this time, the door 20 can be locked with the case 10 when the door opening K is closed by using the cooperation of the locking member 80 and the locking member 90, so that the probability of the door opening K being opened by mistake can be reduced, and the reliability of the testing process of the testing device 100 can be improved.
