[0002] As flexible folding screen technology becomes increasingly mature, flexible folding terminal products have become a major trend. Folding terminal products (such as folding mobile phones, folding tablets, folding computers and other electronic devices) need to meet higher reliability, better operating experience and appearance, so that they can be accepted by consumers.

[0003] During the reliability test acceptance process of folding products, it is necessary to conduct sharp impact tests on the characteristic points of the screen to determine the ability of specific locations to resist sharp impact.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0037] The terms "first" and "second" in the description and claims of the embodiments of the present application are used to distinguish different objects rather than to describe a specific order of objects. For example, a first target object and a second target object are used to distinguish different target objects rather than to describe a specific order of target objects.

[0038] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0039] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more than two. For example, multiple processing units refer to two or more processing units; multiple systems refer to two or more systems.

[0040] The embodiment of the present application provides an impact testing device for performing a sharp impact test on a characteristic point of a screen of a foldable mobile phone, for example, to determine the ability of a specific position to resist sharp point impact. The embodiment of the present application explains the principle of the above-mentioned impact testing device, and its specific structure can be changed as needed and is not limited to the exemplary structure given in the embodiment of the present application.

[0041] Figure 1is a schematic structural diagram of an impact testing device shown as an example; Figure 2 is a partial enlarged schematic diagram of an impact testing device shown as an example; Figure 3 FIG. 1 is a schematic diagram of the structure of the impact testing device shown in another angle.

[0042] like Figure 1-Figure 3 As shown, the impact testing device 100 of the embodiment of the present application includes a lifting mechanism 10, a positioning mechanism 20, a suction mechanism 30 and an impact head 40. The lifting mechanism 10 is used to lift the impact head 40 to a predetermined height to complete the pointed impact test. The positioning mechanism 20 is used to limit the posture of the impact head 40 to ensure that the initial posture of the impact head 40 is vertically downward. In this article, the initial posture of the impact head refers to the posture of the impact head 40 before it reaches a predetermined height and starts to impact downward. The suction mechanism 30 is used to pick up and release the impact head 40 to complete the pointed impact test.

[0043] Exemplarily, in the embodiment of the present application, the lifting mechanism 10 includes a lifting rod 11 and a lifting portion 12. The lifting portion 12 is mounted on the lifting rod 11 and can slide relative to the lifting rod 11. That is, the lifting portion 12 can move along the lifting rod 11. Exemplarily, in the embodiment of the present application, the lifting mechanism 10 includes three lifting rods 11, and the three lifting rods 11 are arranged in a triangle, for example, that is, the three lifting rods 11 can constitute the three vertices of the triangle from a cross-section. The lifting portion 12 is platform-shaped, and three mounting holes are provided on the lifting portion 12 for the lifting rod 11 to pass through. A driving motor can be integrated in the lifting portion 12, or the lifting portion 12 is connected to the driving motor. Through the action of the driving motor, the lifting portion 12 can move up and down along the lifting rod 11, thereby completing the pickup and release of the impact head 40, and then completing the pointed impact test.

[0044] By way of example, in the embodiment of the present application, the positioning mechanism 20 includes a mounting platform 21, a first clamping push rod 22, a second clamping push rod 23, a first support tray 24, and a second support tray 25. The mounting platform 21 is generally rectangular, and a drop hole 26 is formed on the mounting platform 21. When the impact head 40 is released from a predetermined height by the suction mechanism 30, it will fall from the drop hole 26 to impact the screen of the tested prototype 200. By way of example, in the embodiment of the present application, the drop hole 26 is a circular opening.

[0045] The first clamping push rod 22 and the second clamping push rod 23 constitute a clamping unit for clamping the impact head 40. The first clamping push rod 22 and the second clamping push rod 23 are respectively mounted on the first mounting portion 27 and the second mounting portion 28 on both sides. A power mechanism, such as a drive motor, is integrated in the first mounting portion 27 and the second mounting portion 28. Through the action of the power mechanism, the first clamping push rod 22 and the second clamping push rod 23 can be driven to approach each other or move away from each other, thereby switching between the first state and the second state. In the embodiment of the present application, the first state of the first clamping push rod 22 and the second clamping push rod 23 is that they are separated by a certain distance from each other, and together form a accommodating space for accommodating the impact head 40. In the first state, the impact head 40 can be placed in the accommodating space formed by the first clamping push rod 22 and the second clamping push rod 23, and is in a free state. In the embodiment of the present application, the second state of the first clamping push rod 22 and the second clamping push rod 23 is a state in which they are close to each other to reach a minimum distance. Figure 4 As shown, in the second state, the impact head 40 can be clamped by the first clamping push rod 22 and the second clamping push rod 23 and is in a vertical state.

[0046] For example, in the embodiment of the present application, at least two clamping claws are formed on the ends of the first clamping push rod 22 and the second clamping push rod 23 facing each other. When the first clamping push rod 22 and the second clamping push rod 23 are in the second state, the clamping claws can clamp the impact head 40. For example, the clamping claws can be in a right angle shape. Two clamping claws are formed on the ends of the first clamping push rod 22 and the second clamping push rod 23 facing each other. When the first clamping push rod 22 and the second clamping push rod 23 are in the first state, the four clamping claws can enclose a rectangular accommodating space, or a rectangular surrounding space.

[0047] Of course, the shape of the clamp is not limited to a right angle, and can also be other shapes, such as Figure 5 As shown, the clamping jaws can be in an arc shape. Figure 4 and Figure 5 As shown, the clamping jaws of the first clamping push rod 22 and the second clamping push rod 23 are arranged offset from each other so that the impact head 40 can be clamped.

[0048] In the embodiment of the present application, the first support tray 24 and the second support tray 25 constitute a supporting unit. The first support tray 24 and the second support tray 25 are installed on the mounting platform 21 at a position close to the drop hole 26, and the first support tray 24 and the second support tray 25 can be moved closer to each other to close, or separated from each other to open under the action of a power mechanism. When the first support tray 24 and the second support tray 25 can be moved closer to each other to close under the action of the power mechanism, the drop hole 26 is closed by the supporting unit. When the first support tray 24 and the second support tray 25 can be separated from each other under the action of the power mechanism, the drop hole 26 leaks out, and the impact head 40 can fall through the drop hole 26. When the first support tray 24 and the second support tray 25 can be moved closer to each other to close under the action of the power mechanism, the first support tray 24 and the second support tray 25 jointly form a supporting space, and the supporting space is, for example, funnel-shaped. Figure 6 As shown, when the impact head 40 is placed in the accommodation space of the clamping unit, the tip of the impact head 40 falls exactly in the center of the funnel formed by the supporting unit. In this way, since the tip of the impact head 40 is supported by the supporting unit, the main body is located in the accommodation space of the clamping unit, thereby achieving stable placement and facilitating the subsequent clamping of the clamping unit.

[0049] In the embodiment of the present application, the suction mechanism 30 is installed on the upper platform mechanism 10, specifically, for example, on the lifting part 12. The picking mechanism 10 can move with the movement of the lifting part 10. Exemplarily, a pneumatic solenoid valve is provided in the suction mechanism 30, and when the pneumatic solenoid valve is opened, suction can be generated to suck the impact head 40. When the pneumatic solenoid valve is closed, the suction force disappears, and the impact head 40 can be released.

[0050] For example, in the embodiment of the present application, the impact head 40 is in the shape of a pen, which includes a main body (also called a pen body) and a tip (also called a pen tip). The shape of the tip of the impact head 40 is as follows: Figure 7 As shown. In the embodiment of the present application, the body / main body of the impact head 40 is made of a light material such as plastic, and the tip of the impact head (i.e., the pointed part) is made of a heavy material such as stainless steel. In this way, since the pointed part is heavy and the main body is light, the impact head 40 can fall vertically during free fall and accurately complete the impact test.

[0051] The testing principle or testing process of the impact testing device 100 of the embodiment of the present application is as follows:

[0052] First, the impact testing device 100 controls the clamping unit to be in a first state, that is, the first clamping push rod 22 and the second clamping push rod 23 are separated from each other by a certain distance, and controls the supporting unit to be in a closed state, that is, the first supporting tray 24 and the second supporting tray 25 are close to each other to form a supporting space;

[0053] Then, the impact head 40 is placed naturally with the tip facing downward into the clamping unit, that is, into the accommodation space formed by the first clamping push rod 22 and the second clamping push rod 23, so that the tip of the impact head 40 falls exactly at the center of the supporting space formed by the supporting unit;

[0054] Then the impact testing device 100 controls the first clamping push rod 22 and the second clamping push rod 23 of the clamping unit to move toward the center to tighten the accommodation space, and to erect and clamp the impact head 40;

[0055] Then, the impact testing device 100 controls the lifting mechanism 10 to drive the suction mechanism 30 to descend to the tail of the impact head 40, and the suction mechanism 30 opens the pneumatic suction solenoid valve to generate suction to suck the impact head 40;

[0056] Then, the impact testing device 100 controls the first clamping push rod 22 and the second clamping push rod 23 of the clamping unit, and the first support tray 24 and the second support tray 25 of the support unit to move to both sides respectively, so as to leak out the tested sample 200;

[0057] Then, the impact testing device 100 controls the lifting mechanism 10 to lift the impact head 40 and the suction mechanism 30 to the target drop impact height;

[0058] Then, the impact test device 100 controls the suction mechanism 30 to turn off the pneumatic suction solenoid valve. After the suction force disappears, the pointed impact head 40 falls freely and hits the tested sample 200, completing the pointed impact test.

[0059] It can be seen that, with the impact test device 100 of the embodiment of the present application, in addition to the placement of the impact head 40, the picking up, lifting and dropping of the impact head 40, the clamping and releasing of the clamping unit, and the opening and closing of the supporting unit are all completed automatically without manual operation and intervention. That is, with the impact test device 100 of the embodiment of the present application, the positioning, absorption, clamping, release and reabsorption of the pointed impact head can be automatically completed, and the above actions can be repeated reciprocally. During the process, there is no need for the tester to manually intervene many times, which greatly improves the efficiency of the pointed impact test, and also ensures the consistency and accuracy of the test point.

[0060] It should be understood that in the embodiments of the present application, the structure and principle of the impact testing equipment 100 related to the impact test are emphasized, and other related structures can be implemented by various existing technologies. For example, the movement mechanism and principle of the lifting mechanism can be implemented by various existing driving technologies, and the suction structure and principle of the suction mechanism 30 can be implemented by various pneumatic or electromagnetic principles. These do not need to be explained, and technical personnel in this field can choose according to their needs.

[0061] It should also be understood that the embodiment of the present application emphasizes that the impact testing device 100 also includes a control mechanism and a control unit, which is used to control the suction mechanism to complete the suction and release of the impact head, control the lifting mechanism to complete the lifting and lowering, and control the positioning mechanism to complete the positioning, clamping, release and other operations. The control mechanism or control unit can be composed of a processing unit and a corresponding control program, which will not be described in detail here.

[0062] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, 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 embodiments of the present application.
