[0036] It should be understood that "some embodiments" mentioned throughout the specification means that specific features, structures, or characteristics related to the embodiments are included in at least one embodiment of the present utility model. Therefore, "in some embodiments" appearing throughout the specification does not necessarily refer to the same embodiments. In addition, these specific features, structures, or characteristics can be combined in one or more embodiments in any suitable manner.

[0037] The following details a test tooling provided by the present utility model by listing specific embodiments.

[0038] Referring to Figures 1 to 4 , an embodiment of the present utility model provides a test tooling, including a bracket 1 and a bracket 2. The bracket 1 is provided with support assemblies 3 arranged at intervals along the gravity direction. Each support assembly 3 includes a first support beam 31 and a second support beam 32, and there is a height difference between the first support beam 31 and the second support beam 32 in the gravity direction; the bracket 2 is respectively connected to the first support beam 31 and the second support beam 32, and the bracket 2 is used to carry the device to be tested.

[0039] Specifically, the test tooling of the embodiment of the present utility model can carry portable devices such as computer devices, notebook devices, tablet computers, game consoles, etc., so as to perform stability tests on the portable devices. The bracket 1 has a gravity direction and a first direction and a second direction perpendicular to the gravity direction. The gravity direction is as shown by the Z direction in Figure 1 and Figure 2 , and the first direction is as shown by the Figure 1 and Figure 2As shown in the X direction in [reference], the second direction is as shown in Figure 1 and Figure 2 the Y direction in [reference]. Both the first direction X and the second direction Y are perpendicular to the gravity direction. Herein, the "perpendicular" in the embodiments of the present invention not only includes the case of absolute perpendicularity, but also includes the case of approximately perpendicularity in the conventional understanding, that is, the state where the angles formed pairwise between the gravity direction, the first direction X, and the second direction Y are 89° to 91° are all regarded as the gravity direction, the first direction X, and the second direction Y being pairwise perpendicular to each other. The bracket 1 has good strength and stiffness and has good supporting ability. It can be processed from metal, alloy, hard plastic, wood, etc. The specific material of the bracket 1 is not limited in the embodiments of the present invention.

[0040] As Figure 1 shown, the bracket 1 is provided with support assemblies 3 arranged at intervals along the gravity direction. Each group of support assemblies 3 includes a first support beam 31 and a second support beam 32 arranged along the first direction X. In some embodiments, the bracket 1 is provided with a groove, and the first support beam 31 and the second support beam 32 are directly clamped in the groove to realize their installation and fixation on the bracket 1; in some embodiments, the bracket 1 is provided with a protrusion, and the first support beam 31 and the second support beam 32 are provided with clamping grooves cooperating with the protrusion, so as to realize the installation and fixation of the first support beam 31 and the second support beam 32 on the bracket 1 through the cooperation of the protrusion and the clamping groove; in some embodiments, the bracket 1, the first support beam 31, and the second support beam 32 are provided with connection holes for passing through fasteners, so as to realize the installation and fixation of the first support beam 31 and the second support beam 32 on the bracket 1 through the cooperation of the fasteners and the connection holes. It should be noted that the number of support assemblies 3 can be one, two, or more, and can be specifically set according to actual test requirements. If a large number of devices to be tested need to be tested simultaneously during the test process, the number of support assemblies 3 is correspondingly large. If only a small number of devices to be tested need to be tested during the test process, the number of support assemblies 3 is correspondingly small. The number of support assemblies 3 is not limited in the embodiments of the present invention.

[0041] The bracket 2 is respectively connected to the first support beam 31 and the second support beam 32. The bracket 2 is used to carry the device under test to facilitate the testing of the device under test. The bracket 2 also has good strength, stiffness and good supporting ability, and it can be processed from metal, alloy, hard plastic or wood, etc. The number of brackets 2 can be one, two or more, which can be the same as the number of support components 3 or different from the number of support components 3. If the number of brackets 2 is less than the number of support components 3, the corresponding number of support components 3 can be arbitrarily selected to install the bracket 2, and the remaining support components 3 are in an idle state, which is convenient for replenishment when needed later. The test tooling of the embodiment of the present utility model is of a vertical design, and the device under test can be carried in a spaced and stacked manner, greatly reducing the floor area of the test tooling and improving the space utilization rate of the test tooling, and enabling the simultaneous testing of a large number of devices, thereby improving the test efficiency.

[0042] As Figure 2 and Figure 4 shown, the first support beam 31 and the second support beam 32 have a height difference in the gravity direction, which means that the projections of the first support beam 31 and the second support beam 32 along the second direction Y do not coincide. This structure makes the bracket 2 connected to the first support beam 31 and the second support beam 32 in an inclined state in the second direction Y, that is, the angle between the bracket 2 and the gravity direction is an acute angle or an obtuse angle. Since the density of hot air is less than the density of cold air, during the testing process of the device under test, the hot air will continuously flow upward. Setting the bracket 2 in an inclined state is more conducive to the exchange of hot and cold air during the testing process of the device under test, thereby improving the ventilation and heat dissipation effect of the bracket 2 on the device under test and enhancing the safety of the testing process. At the same time, when the bracket 2 is in an inclined state, it can provide a larger viewing range for the inspection personnel, and it is not easy to cause line-of-sight occlusion, so it is more convenient for the inspection personnel to test and check the device under test and analyze the test results of the device. Of course, the height difference between the first support beam 31 and the second support beam 32 along the gravity direction should not be too large to ensure that the inclination of the bracket 2 is within a moderate range. If the height difference between the first support beam 31 and the second support beam 32 along the gravity direction is too large, it will cause the inclination of the bracket 2 to be too large, and then it is easy to cause the device under test carried on the bracket 2 to slide; if the height difference between the first support beam 31 and the second support beam 32 along the gravity direction is too small, it will cause the inclination of the bracket 2 to be too small, and then it is not conducive to the ventilation and heat dissipation of the device under test.

[0043] The test tooling provided by the embodiment of the utility model includes a bracket 1 and a bracket 2. The bracket 1 is provided with support assemblies 3 arranged at intervals along the gravity direction. Each support assembly 3 includes a first support beam 31 and a second support beam 32. The bracket 2 is respectively connected to the first support beam 31 and the second support beam 32. The bracket 2 is used to carry the device under test to facilitate the testing of the device under test. The first support beam 31 and the second support beam 32 have a height difference in the gravity direction, so that the bracket 2 is inclined and connected to the bracket. The inclined bracket 2 is more conducive to the exchange of cold and hot air during the testing process of the device under test, thereby improving the ventilation and heat dissipation effect of the bracket 2 on the device under test, realizing the timely heat dissipation of the device under test, improving the accuracy of the test results and the safety of the test process, and meeting the requirements of simultaneous testing of a large number of devices. At the same time, the inclined bracket 2 can also provide a larger visual field range for the inspectors, making it more convenient for the inspectors to test and check the device under test and analyze the test results, further ensuring the safety of the test process.

[0044] Optionally, referring to Figure 3 , the first support beam 31 and the second support beam 32 are parallel to each other.

[0045] Specifically, the first support beam 31 and the second support beam 32 are parallel to each other. The two sides of the bracket 2 are respectively connected to the first support beam 31 and the second support beam 32, so that the two sides of the bracket 2 are also in a parallel state. The bracket 2 can be a rectangular structure, a square structure, a trapezoidal structure, etc. Its structure is simple, easy to process, and has high stability. At the same time, it can meet the loading requirements of most devices under test.

[0046] Optionally, referring to Figure 3 , the bracket 2 includes a loading part 21 and a connecting part 22; the loading part 21 is used to carry the device under test, and the connecting part 22 is respectively connected to the first support beam 31 and the second support beam 32.

[0047] Specifically, the bracket 2 includes a bearing portion 21 and a connecting portion 22. The bearing portion 21 is located in the central area of the bracket 2. For example, if the bracket 2 is a circular structure, the bearing portion 21 extends radially from the center position to the circumferential side. If the bracket 2 is a rectangular or square structure, the bearing portion 21 extends from the intersection position of the two diagonals to the edge. The bearing portion 21 is used to bear the device under test. The connecting portion 22 is located at the edge or circumferential side of the bearing portion 21, and the connecting portion 22 is respectively connected to the first support beam 31 and the second support beam 32, so as to realize the installation and fixation of the bracket 2. For example, if the bracket 2 is a circular structure, the circumferential part of the bracket 2 forms the connecting portion 22. If the bracket 2 is a rectangular or square structure, the four edges or two opposite edges of the bracket 2 form the connecting portion 22. Since the first support beam 31 and the second support beam 32 are arranged at intervals along the first direction X, the bracket 2 is set as a rectangular or square structure, and two opposite edges of the bracket 2 form the connecting portion 22 and are respectively connected to the first support beam 31 and the second support beam 32.

[0048] Optionally, referring to Figure 3 and Figure 5 , the connecting portion 22 includes a first connecting rod 221 and a second connecting rod 222; the first connecting rod 221 is slidably connected to the first support beam 31, and the second connecting rod 222 is slidably connected to the second support beam 32.

[0049] Specifically, the connecting portion 22 includes a first connecting rod 221 and a second connecting rod 222 arranged along the first direction X. Since the personnel need to frequently check the device under test during the test process, and the field of view is easily blocked by the bracket 1 and other devices under test during the inspection process, the first connecting rod 221 is slidably connected to the first support beam 31 and the second connecting rod 222 is slidably connected to the second support beam 32 in the embodiment of the present invention, so that each bracket 2 can slide out of the bracket 1. As Figure 5 shows a schematic diagram of a bracket 2 sliding out of the bracket 1. After the bracket 2 slides out of the bracket 1, the field of view of the personnel during the inspection of the device under test will not be blocked, which is more convenient for the personnel to check the specific operating state of the device under test and ensure the normal progress of the test process.

[0050] Optionally, referring to Figure 4 , the first support beam 31 is provided with a first slide rail, and the first connecting rod 221 is slidably connected to the first slide rail; the second support beam 32 is provided with a second slide rail, and the second connecting rod 222 is slidably connected to the second slide rail.

[0051] Specifically, in some embodiments, a first sliding rail arranged along the extending direction thereof, i.e., the first direction X, is provided on the first support beam 31, and a sliding groove matching the first sliding rail is provided on the first connecting rod 221, so that the first connecting rod 221 is slidably connected to the first sliding rail through the sliding groove. A second sliding rail arranged along the extending direction thereof, i.e., the first direction X, is provided on the second support beam 32, and a sliding groove matching the second sliding rail is provided on the second connecting rod 222, so that the second connecting rod 222 is slidably connected to the second sliding rail through the sliding groove.

[0052] Optionally, a first hollow channel is provided inside the first support beam 31, and the first hollow channel penetrates at least one end of the first support beam 31; the first connecting rod 221 is movably inserted into the first hollow channel; a second hollow channel is provided inside the second support beam 32, and the second hollow channel penetrates at least one end of the second support beam 32; the second connecting rod 222 is movably inserted into the second hollow channel.

[0053] Specifically, in some embodiments, a first hollow channel arranged along the extending direction thereof, i.e., the first direction X, is provided inside the first support beam 31. The first hollow channel penetrates one end or both ends of the first support beam 31. The first connecting rod 221 is inserted into the first hollow channel and is in clearance fit with the first hollow channel, so that the first connecting rod 221 can move along the first direction X in the first hollow channel. If the first hollow channel penetrates one end of the first support beam 31, the first connecting rod 221 can be pulled out along this end, so that a part of the first connecting rod 221 is located outside the first support beam 31; if the first hollow channel penetrates both ends of the first support beam 31, the first connecting rod 221 can be pulled out along any one end of the first support beam 31, so that a part of the first connecting rod 221 is located outside the first support beam 31.

[0054] Similarly, a second hollow channel arranged along the extending direction thereof, i.e., the first direction X, is provided inside the second support beam 32. The second hollow channel penetrates one end or both ends of the second support beam 32. The second connecting rod 222 is inserted into the second hollow channel and is in clearance fit with the second hollow channel, so that the second connecting rod 222 can move along the first direction X in the second hollow channel. If the second hollow channel penetrates one end of the second support beam 32, the second connecting rod 222 can be pulled out along this end, so that a part of the second connecting rod 222 is located outside the second support beam 32; if the second hollow channel penetrates both ends of the second support beam 32, the second connecting rod 222 can be pulled out along any one end of the second support beam 32, so that a part of the second connecting rod 222 is located outside the second support beam 32.

[0055] It should be noted that to ensure that the first connecting rod 221 can move within the first hollow channel, it is necessary to set the length of the first hollow channel along the first direction X to be greater than the length of the first connecting rod 221, that is, the length of the first support beam 31 along the first direction X is greater than the length of the first connecting rod 221; similarly, to ensure that the second connecting rod 222 can move within the second hollow channel, it is necessary to set the length of the second hollow channel along the first direction X to be greater than the length of the second connecting rod 222, that is, the length of the second support beam 32 along the first direction X is greater than the length of the second connecting rod 222.

[0056] Optionally, referring to Figure 3 , the bearing part 21 includes a first bearing plate 211 and a second bearing plate 212; both ends of the first bearing plate 211 and the second bearing plate 212 are fixedly connected to the connecting part 22, and the first bearing plate 211 and the second bearing plate 212 are arranged at intervals.

[0057] Specifically, the bearing part 21 includes a first bearing plate 211 and a second bearing plate 212 arranged along the second direction Y. The first bearing plate 211 and the second bearing plate 212 are strip-shaped plate structures. To ensure the safe operation of the device under test, a good heat dissipation environment needs to be provided for the device under test during the test. Therefore, in the embodiment of the present invention, the first bearing plate 211 and the second bearing plate 212 are arranged at intervals along the first direction X. Both ends of the first bearing plate 211 and the second bearing plate 212 along the second direction Y are respectively connected to the first connecting rod 221 and the second connecting rod 222. There is a hollow between the first bearing plate 211 and the second bearing plate 212, which is convenient for heat exchange of the heat generated during the operation of the device under test, thus more helpful for improving the ventilation and heat dissipation effect of the device under test.

[0058] Optionally, referring to Figure 3 , the bearing part 21 further includes a third bearing plate 213. One end of the third bearing plate 213 is fixedly connected to the first bearing plate 211, and the other end is fixedly connected to the second bearing plate 212.

[0059] Specifically, the bearing part 21 further includes a third bearing plate 213 arranged along the first direction X. The third bearing plate 213 is also in a strip-shaped plate structure. One end of the third bearing plate 213 is fixedly connected to the first bearing plate 211, and the other end is fixedly connected to the second bearing plate 212. The ways of fixed connection include but are not limited to welding, assembly connection, clamping, etc., and the embodiments of the present invention do not limit this. The setting of the third bearing plate 213 helps to strengthen the overall strength and stiffness of the bracket 2, avoid the collapse phenomenon in the middle part of the bracket 2, and thus improve the stability of the bracket 2 for bearing the device to be measured. In some embodiments, if the dimensions of the first bearing plate 211 and the second bearing plate 212 along the second direction Y are relatively long, two or more third bearing plates 213 can be provided. The multiple third bearing plates 213 are arranged at intervals along the second direction Y, and both ends of each third bearing plate 213 are respectively fixedly connected to the first bearing plate 211 and the second bearing plate 212, so as to ensure the overall strength and stiffness of the bracket 2.

[0060] Optionally, the bracket 1 includes a body 11 and a base 12; the body 11 includes a plurality of upright columns 10 arranged along the gravity direction, and the first support beam 31 and the second support beam 32 are respectively fixedly connected to the upright columns 10; the base 12 is arranged below the body 11 along the gravity direction for supporting the body 11.

[0061] Specifically, the body 11 can be composed of a plurality of upright columns 10. The plurality of upright columns 10 are arranged along the gravity direction, and the plurality of upright columns 10 are connected to each other to form a frame structure. The number of the upright columns 10 can be set according to actual needs. Exemplarily, if the number of the upright columns 10 is three, a triangular prism-shaped bracket 1 can be formed; if the number of the upright columns 10 is four, a square prism-shaped bracket 1 can be formed. In this embodiment, the bracket 1 is composed of four upright columns 10 arranged along the gravity direction, and the four upright columns 10 form a square prism-shaped bracket 1. The first support beam 31 and the second support beam 32 are arranged at intervals along the second direction Y. Among them, both ends of the first support beam 31 are respectively fixedly connected to two upright columns 10, and both ends of the second support beam 32 are respectively fixedly connected to the other two upright columns 10. The ways of fixed connection include but are not limited to fastener assembly connection, welding, clamping, etc., and the embodiments of the present invention do not limit this. The bracket 2 is respectively connected to the first support beam 31 and the second support beam 32, so as to realize the installation and fixation of the bracket 2 on the bracket 1.

[0062] The base 12 is located below the body 11 in the direction of gravity, that is, at the bottom of the body 11. The base 12 is used to support the body 11, so that there is a certain height between the body 11 and the ground. Thus, there is also a certain height between the bracket 2 installed on the body 11 and the ground. This height is more suitable for personnel to place the device under test on the bracket 2 or inspect the device under test, avoiding the risk of personnel getting injured due to excessive bending. It should be noted that the ground refers to the ground plane for people to walk on. If the test tooling is placed on a high platform for use, the surface of the high platform is also regarded as the ground.

[0063] Optionally, referring to Figure 1 and Figure 2 , a roller 4 is connected to the side of the base 12 away from the body 11.

[0064] Specifically, a roller 4 is connected to the side of the base 12 away from the body 11. The side of the base 12 away from the body 11 can be provided with three feet or four feet, and a roller 4 is connected to each foot, thus facilitating the movement of the bracket 1 and also facilitating the movement of a large number of devices under test, effectively improving the flexibility of the test process.

[0065] Finally, it should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or terminal device comprising the element.

[0066] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
