Description

Technical Field

[0001] This application relates to the field of testing technologies, and particularly to testing devices and testing systems. Background Art

[0002] Before being put into use, related components need to undergo comprehensive performance tests to evaluate their reliability and safety performance during long-term use. During the testing process, the related components need to be placed in relevant testing devices for relevant tests. However, when using a testing device to test different related components, there are problems such as a too long testing process and an increased testing cost. Summary of the Utility Model

[0003] Based on this, this application provides a testing device and a testing system, which can simplify the testing process and reduce the testing cost at the same time.

[0004] In a first aspect, this application provides a testing device, including a testing main body and a hoisting mechanism; the testing main body includes a wall structure for carrying a target part, the wall structure defines a receiving cavity for accommodating the target part, and a channel penetrating the wall structure is formed on the wall structure, and the channel is communicated with the receiving cavity; the hoisting mechanism includes a hoisting member and a retracting and releasing assembly arranged outside the testing main body, one end of the hoisting member is connected to the retracting and releasing assembly, and the other end of the hoisting member is used to extend into the receiving cavity through the channel and connect to the target part.

[0005] In the technical solution of the embodiment of this application, by providing a channel of the receiving cavity on the testing main body and cooperating with the testing main body to use the hoisting mechanism, the hoisting member of the hoisting mechanism can extend into the receiving cavity through the channel, and hoist the target part in the receiving cavity. By providing a retracting and releasing assembly in the hoisting mechanism that cooperates with the hoisting member, the hoisting member can be retracted and adjusted by means of the retracting and releasing assembly, and further, the magnitude of the acting force of the target part on the wall structure of the testing main body can be adjusted, so that the testing main body can be applicable to target parts of different weights. Thus, the testing device provided by the embodiment of this application can simplify the testing process and reduce the testing cost at the same time.

[0006] In some embodiments, the wall structure further defines an opening communicated with the receiving cavity, and the channel is communicated with the opening; the retracting and releasing assembly is configured to be able to move in a first direction; the hoisting member can enter the channel and the receiving cavity through the opening in response to the movement of the retracting and releasing assembly in the first direction, and then drive the target part to enter the receiving cavity through the opening; wherein, the first direction is parallel to the opening direction of the opening, and the first direction intersects with the bearing direction of the wall structure.

[0007] By providing an opening that is in communication with both the channel and the receiving cavity, and configuring the retractable component to be movable along a first direction, during the process of the retractable component moving along the first direction and driving the lifting member along the first direction, the lifting member can enter the channel through the opening and extend into the receiving cavity, thereby achieving the transfer of the target member from outside the test body to inside the test body. In this way, it is convenient to load the target member into the test body and to remove the target member from the test body.

[0008] In some embodiments, the channel has a first inner wall and a second inner wall that are oppositely arranged; the testing device further includes a plurality of support members disposed in the channel, and all the support members are arranged at intervals in sequence along the extending direction of the channel; the support member has a first end connected to the first inner wall and a second end supporting the second inner wall; the support member is configured to be capable of elastically deforming under the action of a force so that the second end abuts against or separates from the second inner wall.

[0009] By arranging a plurality of support members at intervals along the extending direction of the channel in the channel, and configuring the support members in a form where one end is fixed and the other end is not fixed, the second end of the support member can abut against the second inner wall, and the support member is supported between the first inner wall and the second inner wall. When a part of the lifting member enters the channel, as the lifting member continues to move along the extending direction of the channel, the support member can elastically deform under the action of the lifting member, so that the second end of the support member can separate from the second inner wall, and the part of the lifting member located in the channel can enter the interval between this support member and the next support member from the gap formed between the second end of the support member and the second inner wall, and the second end of this support member returns to the state of abutting against the second inner wall. In this way, by providing support members that can elastically deform, it is not only beneficial to support the wall structure and improve the reliability of the wall structure, but also beneficial to the movement of the part of the lifting member located in the channel within the channel, realizing the loading of the target member.

[0010] In some embodiments, the support member is configured as a sheet-like member; and / or, the support member is configured to be capable of flexing bidirectionally along the extending direction of the channel; and / or, the direction from the first end to the second end of the support member is parallel to the direction from the first inner wall to the second inner wall; and / or, the first end of the support member is in snap-fit engagement with the first inner wall.

[0011] In this way, by constructing the support member as a sheet-like member, it is convenient for the support member to produce elastic deformation and recovery deformation under the action of the hanging member, thereby realizing the abutment or separation of the second end of the support member with the second inner wall. By configuring the support member to be able to flex in both directions along the extension direction of the channel, it is convenient for the support member to produce elastic deformation in coordination with the moving direction of the hanging member, thereby facilitating the hanging process. By setting the direction from the first end of the support member to the second end to be parallel to the direction from the first inner wall to the second inner wall, it is not only convenient for the second end of the support member to support the second inner wall, but also convenient for cooperating with the movement process of the hanging member in the channel to produce elastic deformation. By engaging the first end of the support member with the first inner wall, it is convenient to install and disassemble the support member.

[0012] In some embodiments, the test body also includes a door body movably connected to the wall structure, the door body is used to open or close the opening; and / or, the test device also includes a guide member, and the retractable assembly is movably connected to the guide member along a first direction.

[0013] In this way, by providing a door body movably connected to the wall structure, when the door body is opened, the target part can be loaded into the test body with the help of a lifting mechanism; when the door body is closed, the test body generally forms a relatively closed space, which is convenient for performing relevant tests on the test body. By providing a guide member, the movement of the retractable assembly along the first direction can be guided.

[0014] In some embodiments, the lifting mechanism also includes an adjusting part arranged outside the test body, and the adjusting part is arranged on the retracting and releasing path of the retracting and releasing assembly for retracting and releasing the lifting part; the adjusting part is configured to be able to extend and retract along the load-bearing direction of the wall structure, and one end of the adjusting part along the load-bearing direction of the wall structure can bear the lifting part.

[0015] In this way, by providing a retractable adjustment member, the inclination angle of the portion of the lifting member located in the channel can be adjusted, thereby improving the contact between the portion of the lifting member located in the channel and the inner wall of the channel, thereby facilitating the lifting mechanism to share the weight of the target member.

[0016] In some embodiments, the testing device also includes a first detection member arranged on the inner wall of the channel; the first detection member is used to detect the force of the lifting member acting on the inner wall of the channel; the adjusting member can be telescopically adjusted along the load-bearing direction of the wall structure in response to the detection signal of the first detection member.

[0017] In this way, by providing the first detection member and enabling the adjustment member to be telescopically adjusted according to the detection signal of the first detection member, the abutment force of the lifting member on the inner wall of the channel can be adjusted, which is further beneficial for the lifting mechanism to share the weight of the target member.

[0018] In some embodiments, one end of the adjusting member that bears the hoisting member is the bearing end; the hoisting mechanism further includes a rotating member rotatably provided at the bearing end, and the circumferential side of the rotating member is used to bear the hoisting member; and / or, the adjusting member is configured as one of a cylinder, an electric cylinder, and a hydraulic cylinder.

[0019] In this way, by providing a rotating member at the bearing end of the adjusting member, when the adjusting member expands and contracts and when the retracting and extending assembly retracts and extends the hoisting member, it is beneficial to reduce the frictional force generated between the hoisting member and the adjusting member, thereby facilitating the adjustment of the attitude and length of the hoisting member. The type of the adjusting member can be flexibly set according to actual usage requirements, and no specific limitation is made here.

[0020] In some embodiments, the wall structure has a bearing surface for bearing the target member; the testing device further includes a second detecting member provided on the bearing surface; the second detecting member is used to detect the acting force of the target member on the bearing surface; the retracting and extending assembly can perform retracting and extending adjustment on the hoisting member in response to the detection signal of the second detecting member.

[0021] In this way, by providing a second detecting member on the bearing surface of the wall structure, the retracting and extending adjustment of the hoisting member can be performed according to the detection signal of the second detecting member, thereby adjusting the acting force of the target member on the bearing surface.

[0022] In some embodiments, there are two channels, and the two channels are arranged opposite to each other in the second direction; there are multiple hoisting mechanisms, and all the hoisting mechanisms are symmetrically arranged on both sides of the testing main body in the second direction; the second direction, the extending direction of the channel, and the bearing direction of the wall structure intersect pairwise.

[0023] In this way, it is beneficial to enable the target member to be loaded into the testing main body more stably.

[0024] In some embodiments, the wall structure includes a bottom wall and a top wall arranged opposite to each other in the bearing direction of the wall structure, and two first side walls arranged opposite to each other in the second direction; each first side wall connects the bottom wall and the top wall; wherein, the mutually facing sides of the first side wall and the top wall jointly define the channel; alternatively, a channel is provided on the side of the first side wall close to the top wall.

[0025] In this way, by jointly defining the channel by the mutually facing sides of the first side wall and the top wall or by providing a channel on the side of the first side wall close to the top wall, it is not only beneficial to hoist the target member at the top of the target member, but also beneficial to arrange the hoisting mechanism.

[0026] In some embodiments, the retracting and extending assembly includes a retracting and extending member rotatably provided, and a driving member connected to the retracting and extending member; one end of the hoisting member is wound around the retracting and extending member, and the driving member is used to drive the retracting and extending member to rotate.

[0027] By setting the driving member and the winding and unwinding member, the rotation of the winding and unwinding member can be controlled by the driving of the driving member, thereby realizing the winding and unwinding of the hoisting member.

[0028] In some embodiments, the testing device further includes a sealing member detachably disposed in the channel.

[0029] In this way, when it is necessary to hoist the target member, the sealing member can be detached from the channel. When the testing main body is loaded with the target member, the sealing member can be disposed in the channel, so that the testing main body generally forms a relatively closed component, thereby performing relevant tests.

[0030] In some embodiments, the hoisting member is configured as a steel wire rope; and / or, the target member includes an energy storage device; and / or, the testing device is configured to perform environmental simulation tests on the energy storage device.

[0031] In this way, by setting the hoisting member as a steel wire rope, the hoisting member has a certain flexibility and a certain structural strength, which is not only beneficial to adjusting the hoisting member, but also beneficial to hoisting target members of different weights. The target member can include an energy storage device, so that the energy storage device can be hoisted and tested. The testing device can be used to perform environmental simulation tests on the energy storage device. For example, the testing device can be an environmental test incubator. The corresponding target member and test type can be selected according to the usage situation, and no specific limitation is made here.

[0062] Referring to "embodiments" herein means that a specific feature, structure or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0063] In the description of the embodiments of the present application, the term "and / or" is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

Therefore, it should not be construed as a limitation to the embodiments of the present application.

[0066] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense.

[0067] Energy storage products need to undergo complete performance tests before being put into use to evaluate their reliability and safety performance during long-term use. Among them, energy storage products are, for example, energy storage containers, energy storage cabinets, etc. Taking the energy storage container as an example, the energy storage container contains an electrical cabinet, and the electrical cabinet houses a battery module containing a number of battery cells. As an energy storage product that supplements the power system, it is used in some application fields, such as short-term power supply for key facilities, adjustment of seasonal regional load curves, etc., to achieve the emergency use of stored energy. At the same time, the energy storage container can also be used for the collection and storage of new green energy for power conversion.

[0068] An environmental test chamber is usually used to simulate the environment for energy storage products. During the test, the energy storage product is placed in the environmental test chamber to test its reliability and safety performance under the simulated environment. However, with the development of energy storage products, to meet different usage requirements, the weights of various energy storage products are different. Since the environmental test chamber has a weight-bearing limit, it is difficult to meet the test requirements of energy storage products with different weights. Therefore, when testing energy storage products with different weights, corresponding test devices need to be remade, which not only lengthens the test process but also increases the test cost.

[0069] To improve at least some of the above problems, the embodiments of the present application provide a test device and a test system, which simplify the test process and reduce the test cost by improving the loading method of the test device. Specifically, by setting relevant structures to cooperate with the corresponding test structures, the relevant structures and the test structures can jointly carry the target part, and the relevant structures can be used to adjust the acting force exerted by the target part on the test structures, so that the test device can be adapted to target parts with different weights.

[0070] It should be noted that the test device provided by the embodiments of the present application can be, but is not limited to, an environmental test chamber, and can also be a device that can be used to test other performances of the target part. The target part involved in the embodiments of the present application can be, but is not limited to, an energy storage product, and can also be other products that need to be tested.

[0071] According to some embodiments of the present application, please refer to Figures 1 to 4 , Figure 1 FIG. 13 is a schematic perspective view of the test device 100 in the first state in some embodiments of the present application. Figure 2 FIG. 14 is a schematic perspective view of the test device 100 in the second state in some embodiments of the present application. Figure 3 FIG. 15 is a schematic front view of a partial cross-section of the test device 100 in some embodiments of the present application. Figure 4 For Figure 3 FIG. 16 is a schematic structural diagram of a partial enlargement at U in FIG. 15 in some embodiments, showing the situation where the test device 100 is loaded with the target part 200. The embodiments of the present application provide a test device 100, including a test main body 110 and a hoisting mechanism 120.

[0072] The test main body 110 is a component mainly used to carry the target part 200 and perform relevant tests on the target part 200. The test main body 110 includes a wall structure 111 for carrying the target part 200. The wall structure 111 defines an accommodation cavity Q for accommodating the target part 200, and a channel p penetrating the wall structure 111 is provided on the wall structure 111. The channel p is communicated with the accommodation cavity Q.

[0073] To Figure 1and Figure 2 Taking Figure 2 as an example, the test body 110 can be configured in a box shape. In the embodiment of the present application, the first direction F1 is the length direction of the test body 110, the second direction F2 is the width direction of the test body 110, and the third direction F3 is the height direction of the test body 110. The first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other pairwise. It can be understood that the first direction F1, the second direction F2, and the third direction F3 are only for the convenience of description and do not limit the embodiments of the present application. For example, in some other embodiments, it may also be that the first direction F1 is the width direction of the test body 110, and the second direction F2 is the length direction of the test body 110. The lengths of the test body 110 in the first direction F1 and the second direction F2 may be equal or unequal. When the test body 110 is configured in other shapes, the respective directions of the test body 110 can be understood in combination with the corresponding shapes, which are not specifically limited herein. Exemplarily, the third direction F3 is parallel to the gravity direction.

[0074] The wall structure 111 is a main component for forming the test body 110. The wall structure 111 is a component with a certain thickness. The wall structure 111 can be composed of multiple walls to define an accommodation cavity Q. The walls can be arranged substantially in a plate shape. Exemplarily, taking Figures 1 to 3 as an example, the wall structure 111 includes a top wall t and a bottom wall d that are oppositely arranged along the third direction F3, two first side walls c1 that are oppositely arranged along the second direction F2, and a second side wall c2 that is arranged along the first direction F1. The first side walls c1 connect the top wall t and the bottom wall d, and the second side wall c2 connects the top wall t and the bottom wall d. In this way, the top wall t, the bottom wall d, the second side wall c2, and the two first side walls c1 enclose and define the accommodation cavity Q and the opening k.

[0075] The wall structure 111 is used to carry the target part 200, that is, the wall structure 111 supports the target part 200 and bears at least a part of the weight of the target part 200. That is to say, a part of the structure of the wall structure 111 is in contact with the target part 200 to support the target part 200 and bear at least a part of the weight of the target part 200. In the embodiment of the present application, exemplarily, with reference to Figure 2 and Figure 3 , the wall structure 111 includes a bottom wall d. The bottom wall d constitutes a part of the structure of the wall structure 111 as described above. The bottom wall d is used to carry the target part 200. It can be seen that the bottom wall d is in contact with the target part 200, and the bottom wall d can bear at least a part of the weight of the target part 200.

[0076] It should be noted that the top wall t, the bottom wall d, the second side wall c2, and the two first side walls c1 are relative to each other. It can be understood that the bottom wall d is the wall for carrying the target member 200 and bearing at least a part of the weight of the target member 200. The top wall t is the wall relative to the bottom wall d, and the side walls (the second side wall c2 and the two first side walls c1) are the walls connecting the top wall t and the bottom wall d. In some other embodiments, the top wall t may not be provided, and the two first side walls c1 are connected on the sides facing away from the bottom wall d, and the connection of the two first side walls c1 is arranged relative to the bottom wall d. In this way, a test body 110 is formed that is different from the box-shaped test body shown in the foregoing embodiments. In these cases, the wall structure 111 is used to carry the target member 200. It can be understood that a part of the structure of the wall structure 111 constitutes the bottom wall d mentioned above. That is to say, the wall structure 111 includes the bottom wall d.

[0077] In still other embodiments, the bottom wall d may not be provided, and the two first side walls c1 are connected on the sides facing away from the top wall t, and the connection of the two first side walls c1 is arranged relative to the top wall t. In this way, a test body 110 is formed that is different from the box-shaped test body shown in the foregoing embodiments. In this case, the wall structure 111 is used to carry the target member 200. It can be understood that a part of the structure of the wall structure 111 constitutes the two first side walls c1 mentioned above. A part of the two first side walls c1 is jointly used to carry the target member 200 and bear at least a part of the weight of the target member 200.

[0078] Therefore, the wall structure 111 can be correspondingly constructed according to the specific structure of the required test body, and no specific limitation is made here. Correspondingly, as long as a part of the structure of the wall structure 111 can be used to carry the target member 200 and bear at least a part of the weight of the target member 200, no specific limitation is made thereto.

[0079] With reference to Figure 4 , the channel p penetrates the wall structure 111, that is, generally speaking, the channel p penetrates the wall structure 111 along the thickness direction of the wall structure 111. Exemplarily, taking Figures 1 to 3 as an example, the channel p can be arranged at positions such as the top wall t, the first side wall c1, the second side wall c2, or the side where the top wall t and the first side wall c1 face each other. The position of the channel p can be set according to the specific use situation, as long as the hoisting of the target member 200 can be realized, and no specific limitation is made here.

[0080] The hoisting mechanism 120 is a mechanism used to hoist the target part 200 and capable of applying a lifting force to the target part 200. The hoisting mechanism 120 includes a hoisting member 121 and a retracting and releasing assembly 122 disposed outside the test main body 110. One end of the hoisting member 121 is connected to the retracting and releasing assembly 122, and the other end of the hoisting member 121 is used to extend into the accommodation cavity Q through the channel p and connect to the target part 200.

[0081] The hoisting mechanism 120 can be located on one side of the test main body 110. Taking Figures 1 to 3 as an example, the situation where the hoisting mechanism 120 is located on both sides of the test main body 110 along the second direction F2 is shown. The hoisting member 121 is generally a longitudinally long member, and the hoisting member 121 is a component with a certain structural strength. The retracting and releasing assembly 122 is a component used to retract and release the hoisting member 121. One end of the hoisting member 121 is connected to the retracting and releasing assembly 122, that is, under the retracting and releasing action of the retracting and releasing assembly 122, one end of the hoisting member 121 can be further retracted or further released. When one end of the hoisting member 121 is further retracted, the other end of the hoisting member 121 is also lifted accordingly, and thus the target part 200 connected to the other end of the hoisting member 121 is also lifted accordingly. When one end of the hoisting member 121 is further released, the other end of the hoisting member 121 is also released accordingly, and thus the target part 200 connected to the other end of the hoisting member 121 is also lowered accordingly. When the target part 200 is fully borne on the wall structure 111, the hoisting member 121 does not apply a force to the target part 200.

[0082] It can be understood that "the target part 200 is fully borne on the wall structure 111" means that the force exerted by the target part 200 on the wall structure 111 is equal to the gravity of the target part 200. Correspondingly, the target part 200 may not be fully borne on the wall structure 111, that is, under the action of the hoisting member 121, the force exerted by the target part 200 on the wall structure 111 is less than the gravity of the target part 200, and the hoisting member 121 can share a part of the gravity of the target part 200. That is to say, the connection state between the other end of the hoisting member 121 and the target part 200 can include the state where "the target part 200 is fully borne on the wall structure 111" and the state where "the hoisting member 121 can share a part of the gravity of the target part 200".

[0083] The other end of the hoisting member 121 extends into the accommodation cavity Q through the channel p, that is, the other end of the hoisting member 121 extends from the outside of the wall structure 111 into the inside of the wall structure 111 through the channel p, and the inside of the wall structure 111 is also the inside of the accommodation cavity Q.

[0084] Therefore, by setting a channel p of the accommodation cavity Q on the test body 110 and cooperating with the test body 110 to use the hoisting mechanism 120, the hoisting member 121 of the hoisting mechanism 120 can extend into the accommodation cavity Q through the channel p, and hoist the target member 200 in the accommodation cavity Q. By providing a retracting and extending assembly 122 in the hoisting mechanism 120 that cooperates with the hoisting member 121, the hoisting member 121 can be retracted and extended and adjusted by means of the retracting and extending assembly 122, and further, the magnitude of the acting force of the target member 200 on the wall structure 111 of the test body 110 can be adjusted, so that the test body 110 can be applicable to target members 200 of different weights. Thus, the test device 100 provided by the embodiment of the present application can simplify the test process while reducing the test cost.

[0085] According to some embodiments of the present application, please continue to refer to Figures 2 to 4 , the wall structure 111 further defines an opening k communicating with the accommodation cavity Q, and the channel p is communicated with the opening k. The retracting and extending assembly 122 is configured to be movable along a first direction F1. The hoisting member 121 can enter the channel p and the accommodation cavity Q through the opening k in response to the movement of the retracting and extending assembly 122 along the first direction F1, and then drive the target member 200 to enter the accommodation cavity Q through the opening k. Wherein, the first direction F1 is parallel to the opening direction of the opening k, and the first direction F1 intersects with the bearing direction of the wall structure 111.

[0086] During the movement of the retracting and extending assembly 122 along the first direction F1, since one end of the hoisting member 121 is connected to the retracting and extending member 122a, the hoisting member 121 can also move along the first direction F1 under the drive of the retracting and extending assembly 122. During the movement of the hoisting member 121 towards the test body 110, the target member 200 can enter the accommodation cavity Q through the opening k outside the test body 110. During the movement of the hoisting member 121 away from the test body 110, the target member 200 can be moved out of the accommodation cavity Q through the opening k to the outside of the test body 110.

[0087] Exemplarily, taking Figure 2 as an example, in combination with referring to Figure 3 , the opening k can be defined by a top wall t, a bottom wall d and two first side walls c1. The bearing direction of the wall structure 111 can be the third direction F3 shown in the figure. At this time, the first direction F1 is perpendicular to the bearing direction of the wall structure 111. Of course, in some other embodiments, the bearing direction of the wall structure 111 can be set at an angle with the third direction F3, that is, the target member 200 carried by the wall structure 111 is generally set at a certain inclination angle. It can be understood that when the bearing direction of the wall structure 111 is the third direction F3 and the third direction F3 is parallel to the gravity direction, it is more beneficial to improve the bearing stability of the wall structure 111, and further facilitate subsequent related tests.

[0088] Thus, by providing an opening k that communicates with both the channel p and the accommodation cavity Q, and configuring the retractable component 122 to be movable along the first direction F1, when the retractable component 122 moves along the first direction F1 and drives the hoisting member 121 along the first direction F1, the hoisting member 121 can enter the channel p through the opening k and extend into the accommodation cavity Q, thereby realizing the transfer of the target member 200 from outside the test body 110 to inside the test body 110. In this way, it is convenient to load the target member 200 into the test body 110 and to remove the target member 200 from the test body 110.

[0089] According to some embodiments of the present application, please continue to refer to Figure 4 and, with reference to Figure 5 Figure 5 For Figure 4 is a schematic structural view of the structure shown in the perspective view along the preset direction W without cross-section processing. The channel p has a first inner wall n1 and a second inner wall n2 that are oppositely arranged. The test device 100 further includes a plurality of support members 130 disposed in the channel p, and all the support members 130 are arranged at intervals in sequence along the extending direction Y of the channel p. The support member 130 has a first end e1 connected to the first inner wall n1 and a second end e2 supporting the second inner wall n2. The support member 130 is configured to be elastically deformed when subjected to a force, so that the second end e2 abuts against or separates from the second inner wall n2.

[0090] Since the channel p penetrates the wall structure 111 and the channel p communicates with the opening k, the channel p has a first inner wall n1 and a second inner wall n2 that are oppositely arranged, and a connecting wall (not shown in the figure) facing the opening k, and the connecting wall connects the first inner wall n1 and the second inner wall n2. When the channel p is provided in the first side wall c1, the first inner wall n1 and the second inner wall n2 are oppositely arranged along the third direction F3. When the channel p is provided in the top wall t, the first inner wall n1 and the second inner wall n2 are oppositely arranged along the second direction F2. When the top wall t and the first side wall c1 jointly define the channel p on the side facing each other, the first inner wall n1 and the second inner wall n2 are respectively constituted by a surface of the first side wall c1 and a surface of the top wall t. With reference to Figure 4 it is shown that the first inner wall n1 is constituted by a surface of the first side wall c1 and the second inner wall n2 is constituted by a surface of the top wall t.

[0091] It can be understood that the first inner wall n1 and the second inner wall n2 are relative to the channel p. For example, for the accommodation cavity Q, both the first inner wall n1 and the second inner wall n2 are located outside the accommodation cavity Q. For another example, for the wall structure 111, the first inner wall n1 and the second inner wall n2 are located inside the wall structure 111.

[0092] ​The support member 130 is a component supported between the first inner wall n1 and the second inner wall n2, and the support member 130 has a certain support performance. The support member 130 has a first end e1 and a second end e2 that are oppositely arranged. Since the first end e1 of the support member 130 is connected to the first inner wall n1 and the second end e2 of the support member 130 abuts against the second inner wall n2, that is, the first end e1 of the support member 130 is relatively fixed and the second end e2 of the support member 130 is relatively unfixed. Also, since the support member 130 can undergo elastic deformation when subjected to a force, that is, the support member 130 has a certain elasticity, with the relatively fixed first end e1 of the support member 130 as the support point and in cooperation with the relatively unfixed second end e2, the support member 130 can flex, and further the second end e2 of the support member 130 can move, causing the second end e2 to separate from the second inner wall n2, and a gap can be formed between the second end e2 and the second inner wall n2. The portion of the hoisting member 121 located in the channel p can pass through the gap and enter the interval formed by the next two adjacent support members 130.

[0093] Exemplarily, with reference to Figure 5 , a situation is illustrated where the portion of the hoisting member 121 located in the channel p is within an interval (defined as the first interval, not marked in the figure). With reference to Figure 6 , Figure 6 FIG. is a schematic structural diagram of a state where the hoisting member 121 and the support member 130 cooperate in some embodiments of the present application. The hoisting member 121 moves along the extending direction Y of the channel p, applying a force to the nearest support member 130, and the support member 130 undergoes elastic deformation, and a gap is formed between the second end e2 of the support member 130 and the second inner wall n2. With reference to Figure 7 , Figure 7 FIG. is a schematic structural diagram of another state where the hoisting member 121 and the support member 130 cooperate in some embodiments of the present application. The hoisting member 121 continues to move along the extending direction Y of the channel p and enters the next interval (defined as the second interval, not marked in the figure) via the gap formed as shown in Figure 6 , and the previously elastically deformed support member 130 returns to its initial shape. Along the extending direction Y of the channel p, the second interval is located downstream of the first interval. Correspondingly, the process when the hoisting member 121 moves in the direction opposite to the extending direction Y of the channel p can be understood with reference to the process when the hoisting member 121 moves along the extending direction Y of the channel p, and will not be elaborated here. In the embodiments of the present application, the extending direction Y of the channel p is parallel to the first direction F1.

[0094] Thus, by arranging a plurality of support members 130 spaced apart along the extending direction Y of the channel p in the channel p, and configuring the support members 130 in a form where one end is fixed and the other end is not fixed, the second end e2 of the support member 130 can abut against the second inner wall n2, and the support member 130 is supported between the first inner wall n1 and the second inner wall n2. When a part of the hoisting member 121 enters the channel p, as the hoisting member 121 continues to move along the extending direction Y of the channel p, the support member 130 can undergo elastic deformation under the action of the hoisting member 121, so that the second end e2 of the support member 130 can be separated from the second inner wall n2, and the part of the hoisting member 121 located in the channel p can enter the space between this support member 130 and the next support member 130 from the gap formed by the second end e2 of the support member 130 and the second inner wall n2, and the second end e2 of this support member 130 returns to the state of abutting against the second inner wall n2. In this way, by providing the support member 130 that can undergo elastic deformation, it is not only beneficial to support the wall structure 111 and improve the reliability of the wall structure 111, but also beneficial to the movement of the part of the hoisting member 121 located in the channel p within the channel p, realizing the loading of the target member 200.

[0095] Of course, in some other embodiments, with reference to Figure 8 and Figure 9 , Figure 8 is Figure 3 a schematic structural diagram of the partial enlarged structure at U in another embodiment, Figure 9 and Figure 8 is a schematic structural diagram of the structure shown in

[0096] viewed from the perspective along the preset direction W without cross-section processing. The first end e1 of the support member 130 can be connected to the second inner wall n2, and the second end e2 of the support member 130 abuts against the first inner wall n1. At this time, the process of the support member 130 generating elasticity can be understood with reference to the foregoing process and will not be elaborated here. Figures 4 to 9 In some other embodiments different from the structure shown in

[0097] According to some embodiments of the present application, please continue to refer to Figures 5 to 7 , Figure 9 , the support member 130 is configured as a sheet-like member.

[0098] The sheet-like member refers to a thinner thickness of the support member 130, so that the support member 130 is generally arranged in a sheet shape. It can be understood that the thinner thickness is relative to the support member 130 as a whole, and does not mean that the thickness of the support member 130 is limited. The thickness direction of the support member 130 can be parallel to the extension direction Y of the channel p, and the preset direction W can be parallel to the first direction F1. In this way, it is conducive to the elastic deformation of the support member 130 under the action of the hanging member 121.

[0099] In this way, by constructing the support member 130 as a sheet-like member, it is beneficial for the support member 130 to generate elastic deformation and recovery deformation under the action of the hanging member 121, thereby achieving the abutment or separation of the second end e2 of the support member 130 with the second inner wall n2.

[0100] According to some embodiments of this application, please continue to refer to Figures 5 to 7 , Figure 9 The support member 130 is configured to be able to bend in both directions along the extension direction Y of the channel p. That is, the support member 130 can bend along the extension direction Y shown in the figure or in the opposite direction of the extension direction Y. According to the movement process of the hanging member 121, the support member 130 can bend accordingly according to the direction of the force of the hanging member 121.

[0101] In this way, by configuring the support member 130 to be able to flex bidirectionally along the extension direction Y of the channel p, it is beneficial for the support member 130 to produce elastic deformation in coordination with the moving direction of the hanging member 121, thereby facilitating the hanging process.

[0102] According to some embodiments of this application, please continue to refer to Figure 4 and Figure 8 , the direction from the first end e1 of the support member 130 to the second end e2 is parallel to the direction from the first inner wall n1 to the second inner wall n2. That is, the direction from the first end e1 of the support member 130 to the second end e2 is the target direction M, and the target direction M is parallel to the direction from the first inner wall n1 to the second inner wall n2. In the case where one surface of the top wall t constitutes the second inner wall n2 and one surface of the first side wall c1 constitutes the first inner wall n1, the target direction M can be perpendicular to the first direction F1, and the target direction M is set at an angle to the second direction F2 and the third direction F3.

[0103] In this way, by setting the direction from the first end e1 of the support member 130 to the second end e2 to be parallel to the direction from the first inner wall n1 to the second inner wall n2, it is not only beneficial for the second end e2 of the support member 130 to support the second inner wall n2, but also beneficial for cooperating with the movement process of the lifting member 121 in the channel p to generate elastic deformation.

[0104] Of course, in some other embodiments, please refer toFigure 10 , Figure 10 for Figure 3 The structural diagram of the partially enlarged structure at the U in some other embodiments, the direction from the first end e1 of the support member 130 to the second end e2 (i.e., the target direction M) can be parallel to the third direction F3. At this time, the direction from the first inner wall n1 to the second inner wall n2 is set at an angle to the target direction M. It can be set according to the specific usage, and is not specifically limited here.

[0105] Understandably, compared to Figure 10 In the illustrated case, Figure 4 and Figure 8 In the illustrated situation, it is more conducive to improving the supporting performance while facilitating the elastic deformation of the support member 130.

[0106] According to some embodiments of this application, please refer to Figure 11 , Figure 11 This is a schematic structural diagram of the matching of the support member 130, the first mounting member A1 and the second mounting member A2 in some embodiments of the present application at a viewing angle, where the first end e1 of the support member 130 is snap-fitted with the first inner wall n1.

[0107] For example, the first end e1 of the support member 130 may be provided with a first mounting member A1, which may be Figure 4 As shown, a second mounting member A2 is provided on the first inner wall n1, and it is also possible to Figure 8 As shown, a second mounting member A2 is disposed on the second inner wall n2. A slot can be disposed on the second mounting member A2, and the first mounting member A1 can be engaged in the slot of the second mounting member A2.

[0108] In this way, by snap-fitting the first end e1 of the support member 130 with the first inner wall n1 , it is easy to install and remove the support member 130 .

[0109] According to some embodiments of this application, please continue to refer to Figure 1 and Figure 2 The test body 110 further includes a door body 112 movably connected to the wall structure 111 , and the door body 112 is used to open or close the opening k. Figure 1 In the first state shown, the door body 112 closes the opening k. Figure 2 In the illustrated second state, the door body 112 opens the opening k.

[0110] For example, Figure 1 and Figure 2For example, the door body 112 can be set as a double-door structure. Of course, the door body 112 can also be set as a single-door structure, which is not specifically limited here. It can be understood that the double-door structure means that the door body 112 includes two parts, the sides of the two parts facing each other can be opened, and the sides of the two parts facing each other can be rotatably connected to the wall structure 111, combined with reference Figure 2 , one part of the door body 112 is rotatably connected to one first side wall c1, and the other part is rotatably connected to the other first side wall c1. The single-open door structure means that the door body 112 is one part, one side of the door body 112 is rotatably connected to the wall structure 111, and the other side can be opened. The corresponding door body 112 can be set according to the specific usage, and no specific limitation is made here.

[0111] In this way, by providing a door body 112 movably connected to the wall structure 111, when the door body 112 opens the opening k, the target part 200 can be loaded into the test body 110 with the help of the lifting mechanism 120; when the door body 112 closes the opening k, the test body 110 roughly forms a relatively closed space, which is convenient for performing relevant tests on the test body 110.

[0112] According to some embodiments of this application, please continue to refer to Figures 1 to 3 The testing device 100 further includes a guide member 140 , and the retractable assembly 122 is movably connected to the guide member 140 along the first direction F1 .

[0113] For example, Figure 1 and Figure 2 As an example, the guide member 140 is configured as a guide rail. Accordingly, the retractable assembly 122 and the guide member 140 can cooperate with each other by means of the structure of the slide groove and the slider to achieve relative movement of the retractable assembly 122 and the guide member 140 in the first direction F1. In addition, a related driving module can be additionally provided to achieve the movement of the retractable assembly 122 on the guide member 140.

[0114] In this way, by providing the guide member 140 , the movement of the retractable assembly 122 along the first direction F1 can be guided.

[0115] According to some embodiments of this application, please continue to refer to Figures 1 to 3 The hanging mechanism 120 further includes an adjusting member 123 disposed outside the test body 110, and the adjusting member 123 is disposed on the retracting and releasing path of the retracting and releasing assembly 122 for retracting and releasing the hanging member 121. The adjusting member 123 is configured to be able to extend and retract along the load-bearing direction of the wall structure 111, and one end of the adjusting member 123 along the load-bearing direction of the wall structure 111 can bear the hanging member 121.

[0116] The adjusting member 123 is a component that can be adjusted. In the embodiment of the present application, the bearing direction of the wall structure 111 is the third direction F3, and the adjusting member 123 can expand and contract along the third direction F3. During the process of the adjusting member 123 expanding and contracting along the third direction F3, the hoisting member 121 carried by the adjusting member 123 can also move in the third direction F3 to adjust the position of the hoisting member 121 in the third direction F3.

[0117] In this way, by providing the telescopic adjusting member 123, the inclination angle of the part of the hoisting member 121 located in the channel p can be adjusted, the situation where the part of the hoisting member 121 located in the channel p abuts against the inner wall of the channel p can be improved, and thus it is beneficial for the hoisting mechanism 120 to share the weight of the target member 200.

[0118] According to some embodiments of the present application, please continue to refer to Figure 2 and Figure 3 , the testing device 100 further includes a first detecting member 160 provided on the inner wall of the channel p. The first detecting member 160 is used to detect the acting force of the hoisting member 121 on the inner wall of the channel p. The adjusting member 123 can perform telescopic adjustment along the bearing direction of the wall structure 111 in response to the detection signal of the first detecting member 160.

[0119] Exemplarily, the first detecting member 160 can be a pressure sensor. The testing device 100 can further include a controller, and the controller is electrically connected to the first detecting member 160 and the adjusting member 123. In this way, the controller can control the expansion and contraction of the adjusting member 123 according to the detection signal of the first detecting member 160, that is, the adjusting member 123 can expand and contract in response to the detection signal of the first detecting member 160. For example, the expansion and contraction of the adjusting member 123 can be controlled by determining whether the magnitude of the acting force of the hoisting member 121 detected by the first detecting member 160 on the inner wall of the channel p is within a preset range or exceeds a preset value. For another example, the first detecting member 160 can also be used to control the hoisting member 121 not to apply an acting force on the wall structure 111.

[0120] In this way, by providing the first detecting member 160 and enabling the adjusting member 123 to perform telescopic adjustment according to the detection signal of the first detecting member 160, the abutting force of the hoisting member 121 on the inner wall of the channel p can be adjusted, and thus it is further beneficial for the hoisting mechanism 120 to share the weight of the target member 200.

[0121] According to some embodiments of the present application, please continue to refer to Figure 2 and Figure 3 , one end of the adjusting member 123 that bears the hoisting member 121 is the bearing end z. The hoisting mechanism 120 further includes a rotating member 124 rotatably provided at the bearing end z, and the circumferential side of the rotating member 124 is used to bear the hoisting member 121.

[0122] Exemplarily, the rotating member 124 may be a wheel structure. The extending direction Y of the rotation axis of the rotating member 124 may be parallel to the first direction F1.

[0123] In this way, by providing the rotating member 124 at the bearing end z of the adjusting member 123, when the adjusting member 123 expands and contracts and when the retracting and deploying assembly 122 retracts and deploys the hoisting member 121, it is beneficial to reduce the frictional force generated between the hoisting member 121 and the adjusting member 123, thereby facilitating the adjustment of the attitude and length of the hoisting member 121.

[0124] According to some embodiments of the present application, please continue to refer to Figure 2 and Figure 3 , the adjusting member 123 is configured as one of a cylinder, an electric cylinder, and a hydraulic cylinder. In the embodiment of the present application, the adjusting member 123 may be a hydraulic cylinder.

[0125] In this way, the type of the adjusting member 123 can be flexibly set according to actual usage requirements, and no specific limitation is made here.

[0126] According to some embodiments of the present application, please continue to refer to Figures 1 to 3 , the testing device 100 further includes a transfer member 150, and the adjusting member 123 and the retracting and deploying assembly 122 may both be provided on the transfer member 150. The transfer member 150 is movably connected to the guiding member 140 along the first direction F1. In this way, synchronous movement of the adjusting member 123 and the retracting and deploying assembly 122 can be achieved.

[0127] Of course, in some other embodiments, the adjusting member 123 may be movably connected to a corresponding guiding structure along the first direction F1, and synchronous movement of the adjusting member 123 and the retracting and deploying assembly 122 is achieved by synchronously controlling the adjusting member 123 and the retracting and deploying assembly 122. It can be set according to actual usage conditions, and no specific limitation is made here.

[0128] According to some embodiments of the present application, please continue to refer to Figure 2 and Figure 3 , the wall structure 111 has a bearing surface m for bearing the target member 200. The testing device 100 further includes a second detecting member 170 provided on the bearing surface m. The second detecting member 170 is used to detect the acting force of the target member 200 on the bearing surface m. The retracting and deploying assembly 122 can retract and deploy the hoisting member 121 in response to the detection signal of the second detecting member 170.

[0129] Exemplarily, the bearing surface m may be the surface of the bottom wall d facing the accommodating cavity Q. The second detecting member 170 may be a pressure sensor or a weighbridge. The testing device 100 may further include the aforementioned controller, and the controller is electrically connected to the second detecting member 170 and the retracting and extending assembly 122. In this way, the controller can control the retracting and extending of the retracting and extending assembly 122 according to the detection signal of the second detecting member 170, that is, the retracting and extending assembly 122 can extend and retract in response to the detection signal of the first detecting member 160. For example, the retracting and extending of the retracting and extending assembly 122 can be controlled by determining whether the magnitude of the acting force of the target member 200 detected by the second detecting member 170 on the bearing surface m is within a preset range or exceeds a preset value.

[0130] In this way, by arranging the second detecting member 170 on the bearing surface m of the wall structure 111, the retracting and extending of the hoisting member 121 can be adjusted according to the detection signal of the second detecting member 170, and further, the acting force of the target member 200 on the bearing surface m can be adjusted.

[0131] According to some embodiments of the present application, please continue to refer to Figures 1 to 4 , there are two channels p, and the two channels p are arranged opposite to each other along the second direction F2. A plurality of hoisting mechanisms 120 are provided, and all the hoisting mechanisms 120 are symmetrically arranged on both sides of the testing main body 110 along the second direction F2. The second direction F2, the extending direction Y of the channel p, and the bearing direction of the wall structure 111 intersect pairwise.

[0132] Exemplarily, taking Figure 1 and Figure 2 as an example, two hoisting mechanisms 120 are respectively provided on the sides of the two first side walls c1 away from each other, that is, there are four hoisting mechanisms 120. When the hoisting members 121 of the four hoisting mechanisms 120 are connected to the target member 200, there are four hoisting points on the target member 200. When the target member 200 is generally a cuboid structure as schematically shown in the figure, the four hoisting points are respectively located at the four corner portions of the top of the target member 200. Of course, other numbers of hoisting mechanisms 120 can also be provided and the hoisting mechanisms 120 can be arranged in other forms as long as it is convenient to stably transfer the target member 200, and no specific limitation is made here.

[0133] Since there are two channels p, and the two channels p are generally located on both sides of the target member 200 along the second direction F2, further, by symmetrically arranging the hoisting mechanisms 120 on both sides of the testing main body 110 along the second direction F2, it is beneficial to make the target member 200 in a more stable hoisting state. In this way, it is beneficial to enable the target member 200 to be loaded into the testing main body 110 more smoothly.

[0134] According to some embodiments of the present application, please continue to refer to Figures 1 to 4, the wall structure 111 includes a bottom wall d and a top wall t that are oppositely arranged along the load-bearing direction of the wall structure 111, and two first side walls c1 that are oppositely arranged along the second direction F2. Each first side wall c1 connects the bottom wall d and the top wall t. Wherein, one side of the first side wall c1 and the top wall t facing each other jointly defines a channel p; alternatively, a channel p is provided on one side of the first side wall c1 close to the top wall t.

[0135] Exemplarily, Figure 4 illustrates a situation where one side of the first side wall c1 and the top wall t facing each other jointly defines a channel p.

[0136] In this way, by jointly defining the channel p by one side of the first side wall c1 and the top wall t facing each other or by providing the channel p on one side of the first side wall c1 close to the top wall t, it is not only beneficial to hoist the target part 200 at the top of the target part 200, but also beneficial to arrange the hoisting mechanism 120.

[0137] According to some embodiments of the present application, please continue to refer to Figures 1 to 3 , the winding and unwinding assembly 122 includes a rotatably arranged winding and unwinding member 122a, and a driving member 122b connected to the winding and unwinding member 122a. One end of the hoisting member 121 is wound around the winding and unwinding member 122a, and the driving member 122b is used to drive the winding and unwinding member 122a to rotate.

[0138] Exemplarily, the winding and unwinding member 122a can be configured as a wire winding wheel. The driving member 122b can be a driving motor. The output shaft of the driving member 122b can be connected to the winding and unwinding member 122a through a transmission assembly 122c. The transmission assembly 122c can be a belt transmission structure, and the belt transmission structure can be configured to achieve the required transmission ratio.

[0139] In this way, by providing the driving member 122b and the winding and unwinding member 122a, the rotation of the winding and unwinding member 122a can be controlled by the driving of the driving member 122b, and thus the winding and unwinding of the hoisting member 121 can be realized.

[0140] According to some embodiments of the present application, please continue to refer to Figure 4 , Figure 8 and Figure 10 , the testing device 100 further includes a sealing member 180, and the sealing member 180 is detachably arranged in the channel p.

[0141] Exemplarily, the material of the sealing member 180 can be a material such as rubber that can be sealed, and no specific limitation is made here.

[0142] Thus, when the target member 200 needs to be lifted, the seal member 180 can be detached from the passage p. When the test body 110 is loaded with the target member 200, the seal member 180 can be disposed in the passage p so that the test body 110 substantially forms a relatively enclosed component, thereby performing relevant tests.

[0143] According to some embodiments of the present application, please continue to refer to Figures 1 to 3 , the lifting member 121 is configured as a wire rope; and / or, the target member 200 includes an energy storage device; and / or, the test device 100 is configured to perform an environmental simulation test on the energy storage device.

[0144] Thus, by setting the lifting member 121 as a wire rope, the lifting member 121 has a certain flexibility and a certain structural strength, which is not only beneficial to adjusting the lifting member 121, but also beneficial to the lifting member 121 lifting target members 200 of different weights. The target member 200 may include an energy storage device, so that the energy storage device can be lifted and tested. The test device 100 can be used to perform an environmental simulation test on the energy storage device. For example, the test device 100 can be an environmental test incubator. The corresponding target member 200 and test type can be selected according to the usage situation, and no specific limitation is made here.

[0145] It should be noted that, in some of the above embodiments, for some of the adjustment processes shown, if possible, a manual adjustment method can also be adopted. It can be set according to the specific usage situation, and no specific limitation is made here.

[0146] According to some embodiments of the present application, the present application provides a test system, including the test device 100 in any of the above embodiments.

[0147] Exemplarily, the test system may further include other devices that cooperate with the test device 100, such as a control device or an auxiliary test device 100. It can be set according to the actual usage situation, and no specific limitation is made here.

[0148] The test system also has the same advantages as the test device 100 in any of the above embodiments, which will not be elaborated here.

[0149] Next, in combination with the relevant combinations shown in some of the above embodiments, taking the target member 200 as an energy storage container as an example, the process of loading the target member 200 into the test body 110 in the embodiments of the present application will be exemplarily described.

[0150] Exemplarily, in combination with reference to Figures 1 to 4, first, open the door body 112 of the test main body 110, and first install the guide members 140 and the transfer members 150 movably connected to the guide members 140 along the first direction F1 on both sides of the test main body 110 along the second direction F2; secondly, fix the two adjusting members 123 to one of the transfer members 150 by means of bolting, and fix the other two adjusting members 123 to the other transfer member 150; then, install two hoisting mechanisms 120 on both transfer members 150, one end of the hoisting member 121 is connected to the winding and unwinding assembly 122, adjust the extending length of the hoisting member 121, and make the rotating member 124 on the adjusting member 123 bear a part of the extending hoisting member 121; then, connect the other ends of the four hoisting members 121 to the four corners of the top of the energy storage container respectively, adjust the length of the hoisting member 121 through the winding and unwinding assembly 122, and lift and suspend the energy storage container by the hoisting mechanism 120; then, move the transfer member 150 along the first direction F1 so that the energy storage container enters the accommodation cavity Q through the opening k; then, adjust the length of the hoisting member 121 through the winding and unwinding assembly 122, and slowly lower the energy storage container; then, monitor the magnitudes of the corresponding acting forces by means of the first detection member 160 and the second detection member 170, and correspondingly control the telescoping of the adjusting member 123 and the winding and unwinding of the winding and unwinding member 122a according to the detection signals of the first detection member 160 and the second detection member 170 until the loading requirements of the test main body 110 are met; finally, close the door body 112, and set a sealing member 180 at the passage p to perform the corresponding test.

[0151] It should be noted that the corresponding adjustment process can be realized by using the first detection member 160 and the second detection member 170 according to the usage requirements. For example, during the process of the energy storage container entering the accommodation cavity Q through the opening k, the telescoping of the adjusting member 123 can also be controlled by the first detection member 160. Another example is that the door body 112 of the test main body 110 can also be opened after all components of the test device 100 are installed. The relevant process can be carried out according to the specific usage requirements, and no specific limitation is made here. After the test is completed, the process of moving the energy storage container out of the test main body 110 can refer to the above operation process, and no limitation and elaboration are made here.

[0152] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present application, and they should all be covered within the scope of the claims and the description of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
