However, in actual use, products are exposed to varying environmental temperatures, such as in winter and summer, and are dropped onto different surfaces, such as wood floors, grass, and concrete. Therefore, existing drop resistance testing methods are incomplete, failing to include drop resistance results under different environmental temperatures and on different surfaces. This means that the design and materials of current products cannot guarantee their safety and reliability during use. Summary of the Invention

[0037] Figure 2 This is a block diagram of the drop resistance testing system in this invention. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0039] It should be noted that in the description of this invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0040] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] Example 1:

[0042] like Figure 1 As shown, a drop resistance testing method includes the following steps:

[0043] Step S10: Obtain the target ambient temperature based on the sample to be tested;

[0044] In this embodiment, the sample to be tested can be, but is not limited to, VR glasses. The target ambient temperature can be a preset value or an input value, which can be input in real time through the human-computer interaction unit. In a preferred embodiment, the target ambient temperature can be set according to the actual ambient temperature of the sample under test. Specifically, the target ambient temperature can include high and low temperatures in a broad sense, and can include the highest outdoor temperature (40°C) and the lowest living temperature (-20°C) in a narrow sense.

[0045] Step S20: Adjust the experimental environment temperature to the target environment temperature;

[0046] In this embodiment, the experimental environment temperature can be, but is not limited to, the laboratory temperature used for drop experiments. The experimental environment temperature can be adjusted using a temperature regulator, which can be operated manually or automatically.

[0047] Step S30: Obtain at least one target height, at least one target angle, and at least one swinging fall state;

[0048] In this embodiment, the height of each target is within the range of 1-2 meters, and the angle of each target is within the range of 360°. The target height, target angle, and swing fall state can all be preset values ​​or real-time input values, and the number of target heights, target angles, and swing fall states are selected or set according to the sample to be tested.

[0049] Step S40: Under the current ground conditions, control the sample to be tested to drop from different target heights and / or different target angles, record the degree of damage after the drop, and obtain the corresponding test data; in a preferred embodiment, the ground conditions are set according to the actual ground used by the sample to be tested, so as to obtain more comprehensive drop resistance test results of the product.

[0050] In this embodiment, the ground surface can be wood flooring, concrete, or grass.

[0051] Step S50: Control the sample to be tested to drop under different swing and drop states, record the degree of damage after the drop, and obtain the corresponding test data.

[0052] Step S60: Determine whether it is necessary to switch the ground status;

[0053] If a switch is required, control the switch to change the current ground state, and then execute step S30;

[0054] If no switching is required, the drop resistance test results are obtained based on the recorded test data.

[0055] It should be noted that whether to switch the ground state can be determined manually based on the actual test results, or it can be determined automatically. In automatic judgment, it can check whether a ground state switch command has been received. This command can be preset based on the sample under test, or it can be input in real time based on the actual test results of the sample. Real-time input includes on-site input and remote wireless input. Regardless of the judgment method, switching the ground state can comprehensively reflect the product's drop resistance test results.

[0056] like Figure 1 As shown, the drop resistance testing method of this invention is divided into high-temperature testing and low-temperature testing based on the experimental environment temperature for drop testing. The main difference between high-temperature testing and low-temperature testing is the experimental environment temperature; all other aspects are the same. After determining the experimental environment temperature, the ground condition for the drop test is determined, such as choosing one of wood flooring, concrete, or grass as the current ground condition for the drop test. Then, the sample to be tested is controlled to drop from different heights, angles, and swing states, and the degree of damage to the sample is recorded to obtain the corresponding drop resistance test results.

[0057] After completing the above tests, switch the current ground condition and perform the drop test again to obtain the drop resistance test results of the sample under different ground conditions.

[0058] After testing under different ground conditions, the test environment temperature is switched, and the drop test is repeated to obtain the drop resistance test results under different environmental temperatures.

[0059] As can be seen, this invention can provide a more comprehensive understanding of the drop resistance of the sample under test, helping to identify potential weaknesses in product design and materials, thereby improving the overall durability and reliability of the product, ensuring that the product is safer and more reliable during user use, enhancing the user experience, and reducing problems caused by equipment damage.

[0060] The drop resistance testing method of the present invention further includes vibration testing, and the specific step S25 is as follows:

[0061] Control the sample to be tested to vibrate at different vibration frequencies, different vibration amplitudes and / or different vibration times;

[0062] Record the degree of damage to the sample to be tested to obtain the corresponding test data.

[0063] This invention simulates the impact of a test sample falling onto a moving vehicle during use by adding vibration detection. The vibration performance is tested by controlling the sample to undergo vibration at different frequencies, amplitudes, and durations. Based on the degree of damage to the sample, the vibration performance test results are obtained. These results provide a more comprehensive understanding of the sample's impact resistance, identify potential weaknesses in product design and materials, thereby improving the overall durability and reliability of the product and ensuring greater safety and reliability for users.

[0064] In this embodiment, step S30 includes:

[0065] Obtain at least one target height and at least one target angle;

[0066] Based on the height and angle of each target, n detection points are formed, where n is a positive integer and n is 10;

[0067] Step S40 includes:

[0068] Under the current ground conditions, the sample to be tested is controlled to fall from n detection points, and the degree of damage after the fall is recorded to obtain the corresponding detection data.

[0069] In this embodiment, step S40 specifically includes:

[0070] Based on n detection points, set the operating parameters of the drop detection equipment;

[0071] The sample to be tested is fixed to the drop section of the drop detection device.

[0072] Under the current ground conditions, the fall detection equipment operates according to the set working parameters;

[0073] The sample to be tested is dropped from the test point, and the degree of damage after the drop is recorded to obtain the corresponding test data.

[0074] As can be seen from the above steps, the present invention can form multiple detection points by using different target heights and different target angles, so that the drop resistance test of the sample to be tested can be carried out continuously and efficiently, thus improving the testing efficiency. Of course, the number of detection points can be set on-site according to the actual testing situation.

[0075] Example 2:

[0076] like Figure 2 As shown, a drop resistance testing system includes a control unit and a temperature regulation unit and a drop detection unit that are respectively communicated and connected to the control unit.

[0077] The control unit is used to acquire the target ambient temperature, at least one target height, at least one target angle and / or at least one swinging drop state according to the sample to be tested, and then transmit the corresponding ambient temperature signal to the temperature adjustment unit, and transmit the drop parameter signal corresponding to at least one target height, at least one target angle and / or at least one swinging drop state to the drop detection unit.

[0078] The temperature control unit is used to adjust the experimental environment temperature to the target environment temperature based on the received ambient temperature signal. In this embodiment, the temperature control unit adjusts the experimental environment temperature through a temperature regulator, which can specifically be the laboratory temperature for drop testing.

[0079] The drop detection unit is used to control the sample under test to be dropped from different target heights, different target angles, and / or different swinging drop states based on the received drop parameter signals under the current ground conditions, thereby obtaining drop resistance test results. In this embodiment, the drop detection unit can use a drop detector for detection. First, the height, angle, and swinging drop state of the drop detector are set. Then, the sample under test is installed on the gripper of the drop detector, and then the drop detector is activated to perform drop detection. Drop detection is performed at different heights and angles, and the degree of damage after the drop is recorded.

[0080] The drop resistance testing system of the present invention further includes a vibration detection unit communicatively connected to the control unit. The control unit acquires different vibration frequencies, amplitudes, and durations based on the sample under test, and then transmits vibration parameter signals corresponding to these frequencies, amplitudes, and durations to the vibration detection unit. The vibration detection unit, based on the received vibration parameter signals, controls the sample under test to vibrate at different frequencies, amplitudes, and / or durations to obtain corresponding shock resistance test data. Specifically, VR glasses are placed on a vibration table, and different vibration frequencies and amplitudes are set. Testing is performed within a certain vibration time, and the degree of damage to the device is observed and recorded. By adding vibration detection, the system simulates the VR glasses being dropped onto a moving vehicle during use, thus testing its shock resistance performance.

[0081] The impact resistance testing system of the present invention also includes an environmental conditioner, which is used to adjust the current ground condition, which may specifically be wood flooring, concrete, or grass.

[0082] like Figure 2As shown, the drop resistance testing system of the present invention can first determine the sample to be tested, and then select the experimental equipment required for the experiment based on the sample, such as an environmental conditioner, a temperature regulator used in the temperature control unit, and a drop detector used in the drop detection unit. Then, testing is performed under different conditions, specifically high-temperature testing and low-temperature testing. High-temperature testing corresponds to the actual ambient temperature of the sample's operating environment, such as a maximum outdoor temperature of 40°C in summer, while low-temperature testing corresponds to the actual ambient temperature of the sample's operating environment, such as a minimum living temperature of -20°C in winter. Of course, the high-temperature and low-temperature testing settings can be adjusted according to the actual ambient temperature of the sample's operating environment through the temperature regulator. The present invention utilizes the laboratory temperature of drop testing to simulate the actual operating ambient temperature.

[0083] After the control unit adjusts the experimental environment temperature to the target environment temperature (high or low temperature) according to the sample to be tested, the environmental regulator adjusts the current ground condition. Specifically, the current ground condition can be wooden floor, concrete, or grass.

[0084] After the control unit has adjusted the environmental regulator, the drop detector is set according to different target heights, target angles, and swing and drop states. Then, the sample to be tested is fixed on the gripper of the drop detector, the drop detector causes the sample to fall, the degree of damage to the sample is recorded, and the drop resistance test result is obtained.

[0085] In this embodiment, after determining whether to perform high-temperature testing or low-temperature testing, vibration testing - seismic performance testing can be carried out.

[0086] Therefore, this invention can provide a more comprehensive understanding of the drop resistance of the sample under test, detect and help identify potential weaknesses in product design and materials, thereby improving the overall durability and reliability of the product and ensuring that the product is safer and more reliable during user use. This not only enhances the user experience but also reduces problems caused by equipment damage.

[0087] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, improvements to the same drop resistance testing method and drop resistance testing system made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
