[0048] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0049] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0050] Combination Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a drop test device, which includes a lifting assembly 1, a sliding assembly 2, a holding assembly 3, and a pad assembly 4; the lifting assembly 1 has a lifting member 11 and a drive motor 12 that is pulsatorically connected to the lifting member 11; the sliding assembly 2 is detachably connected to the lifting member 11 and can move upward synchronously with the lifting member 11 or fall freely independently after being separated from the lifting member 11; the holding assembly 3 is connected to the sliding assembly 2 and has a holding space for holding the item to be tested; the pad assembly 4 is correspondingly disposed below the holding assembly 3 and is used to receive the holding assembly 3 and detect the impact load when the holding assembly 3 falls; wherein, the drive motor 12 can electrically drive the lifting member 11 to move upward to a fixed height.

[0051] This drop testing device can be used, but is not limited to, for testing the drop and shock resistance of laptops. Examples will be given below.

[0052] In practical use, the drop test device first places the laptop under test in the holding space of the holding component 3, and then connects the holding component 3 to the lifting component 11 in the lifting component 1 through the sliding component 2. Then, the drive motor 12 drives the lifting component 11 to rise to a fixed height, and then the sliding component 2 is separated from the lifting component 11. At this time, the sliding component 2, the holding component 3 and the laptop can perform free fall and fall onto the pad component 4, where the impact load during the fall is detected by the pad component 4. In this way, the drop resistance and shock resistance performance of the laptop can be calculated.

[0053] Compared with the manual adjustment of the drop height in the existing drop test device, the drop test device provided in this embodiment can electrically control the rising height of the lifting component 11 through the drive motor 12, and can also automatically separate the sliding component 2 from the lifting component 11. The tester only needs to start the drop test device to automatically complete the drop and shock resistance test of the laptop computer. It has the beneficial effects of accurately controlling the drop height and high test efficiency.

[0054] In one embodiment, the lifting assembly 1 further includes a rotating screw 13 and a guide slide 14; the rotating screw 13 extends along the lifting direction and one end is connected to the drive motor 12 for transmission; the guide slide 14 is arranged parallel to the rotating screw 13 and at least one is spaced apart around the circumference of the rotating screw 13; wherein, the lifting member 11 is respectively fitted onto the rotating screw 13 and the guide slide 14, and has a threaded hole that engages with the rotating screw 13 for transmission and a through hole that slides with the guide slide 14.

[0055] Specifically, in combination Figure 1To further explain, the lifting assembly 1 is provided with parallel and spaced guide slide rods 14 and rotating screws 13, and the lifting component 11 is respectively fitted onto the rotating screws 13 and guide slide rods 14, and has a threaded hole that engages with the rotating screws 13 and a through hole that slides with the guide slide rods 14. In this way, when the rotating screws 13 are driven by the drive motor 12 to rotate around their own axis, a transmission mechanism similar to a lead screw and nut can be formed between the lifting component 11 and the rotating screws 13, so that the lifting component 11 can move upward along the rotating screws 13 and guide slide rods 14. According to the pitch of the peripheral wall of the rotating screws 13 and the number of rotation output revolutions of the drive motor 12, the function of precisely controlling the lifting height of the lifting component 11 can be realized.

[0056] The specific arrangement of the above-mentioned lifting component 1 has the advantages of simple structure and the ability to control the lifting height of the lifting component 11 by controlling the number of rotation output revolutions of the drive motor 12.

[0057] In one embodiment, the lifting assembly 1 further includes a magnetically attached rotating wheel 15 that can be detachably connected to the sliding assembly 2; the lifting member 11 is provided with an electromagnet 111, and the electromagnet 111 can attract or repel the magnetically attached rotating wheel 15 when energized; the magnetically attached rotating wheel 15 can rotate toward or away from the lifting member 11 under the action of magnetic force, and connect or separate from the lifting member 11 accordingly.

[0058] Specifically, in combination Figure 3 and Figure 4 To further explain, a magnetically attached rotating wheel 15 is provided in the lifting component 1 for detachable connection with the sliding component 2, and an electromagnet 111 is correspondingly provided in the lifting component 11. When the electromagnet 111 is energized, it can attract or repel the magnetically attached rotating wheel 15. In this way, the magnetically attached rotating wheel 15 can connect or separate the sliding component 2 from the lifting component 11 by rotating towards or away from the lifting component 11 under the action of magnetic force.

[0059] The specific arrangement of the magnetically attached rotating wheel 15 and the electromagnet 111 allows the lifting component 11 to be connected or separated from the sliding component 2 through the magnetic attraction or repulsion between the two, which has the beneficial effects of stable and firm connection and fast and efficient separation response.

[0060] In one embodiment, the lifting member 11 is further provided with a mounting plate 112 for mounting the magnetic clamping wheel 15; the magnetic clamping wheel 15 has a wheel axle 154 and a limiting head 155 located on the peripheral wall of the end of the wheel axle 154; the mounting plate 112 is provided with a shaft hole for mounting the wheel axle 154 and a limiting fan hole 112a for limiting and accommodating the limiting head 155; wherein, the limiting head 155 can move along the limiting fan hole 112a to limit the rotation angle of the wheel axle 154.

[0061] Specifically, in combination Figure 4 and Figure 5 In further detail, the lifting component 11 is also provided with a mounting plate 112 for mounting the magnetic clamping wheel 15, and the mounting plate 112 is provided with a shaft hole for mounting the wheel axle 154 and a limiting fan hole 112a for limiting and accommodating the limiting head 155. In this way, the magnetic clamping wheel 15 can be hinged and inserted into the shaft hole in the mounting plate 112 through the wheel axle 154. When the wheel axle 154 rotates in the shaft hole, the limiting head 155 can move along the limiting fan hole 112a and be limited by both ends of the limiting fan hole 112a, thereby realizing the function of limiting the rotation angle of the wheel axle 154.

[0062] The specific arrangement of the aforementioned lifting component 11 and magnetically attached rotating wheel 15 has the beneficial effect of simple structure and limiting the rotation angle of the wheel axle 154 by means of the limiting head 155 rotating in a specific way in the limiting fan hole 112a.

[0063] In one embodiment, the sliding assembly 2 includes a sliding plate 21; a first locking head 151 and a second locking head 152 are respectively provided on the circumferential surface of the magnetic locking wheel 15, and a permanent magnet 153 is provided in the first locking head 151; the sliding plate 21 has a sliding sleeve part 211 that is slidably connected to the guide slide rod 14 and a locking part 212 corresponding to the magnetic locking wheel 15; wherein, when the electromagnet 111 can attract or repel the permanent magnet in the first locking head 151 in the energized state, the magnetic locking wheel 15 correspondingly drives the second locking head 152 to separate or lock with the locking part 212.

[0064] Specifically, in combination Figure 3 , Figure 4 and Figure 5 To further explain, a first locking head 151 and a second locking head 152 are respectively provided on the circumferential surface of the magnetic locking wheel 15, and a permanent magnet 153 is provided in the first locking head 151. In this way, when the electromagnet 111 is energized, it attracts the permanent magnet in the first locking head 151, and the second locking head 152 can engage with the locking part 212 in the sliding plate 21 to realize the function of connecting the lifting member 11 and the sliding component 2. When the electromagnet 111 is energized in the reverse direction, it repels the permanent magnet in the first locking head 151, and the second locking head 152 no longer engages with the locking part 212 in the sliding plate 21, thus realizing the function of separating the lifting member 11 and the sliding component 2.

[0065] The specific arrangement of the sliding plate 21 and the magnetically attached rotating wheel 15 has the advantages of simple structure and the ability to connect or separate the lifting component 11 and the sliding assembly 2 by means of the attraction or repulsion between the electromagnet 111 and the permanent magnet.

[0066] In one embodiment, the container assembly 3 includes a container hanging plate 31; two container hanging plates 31 are arranged in parallel at intervals and are connected by a connecting column to form a container space.

[0067] Specifically, in combination Figure 3 To further explain, the housing assembly 3 has two parallel and spaced housing plates 31, which are connected by a connecting post to form a housing space. In this way, the laptop computer to be tested can be inserted into the housing space and can be fully subjected to impact load during the drop test.

[0068] The specific configuration of the aforementioned container component 3 has the advantages of simple structure, stable container for the laptop under test, and no impact on its drop test performance.

[0069] In one embodiment, an angle adjustment mechanism is further provided between the sliding component 2 and the holding plate 31; the angle adjustment mechanism is used to adjust the installation angle between the holding plate 31 and the sliding component 2.

[0070] Specifically, in combination Figure 3 To elaborate further, an angle adjustment mechanism is provided between the sliding component 2 and the mounting plate 31. The angle adjustment mechanism can adjust the installation angle between the mounting plate 31 and the sliding component 2, thereby adjusting the angle between the laptop under test and the vertical plane in the mounting space. This allows the laptop drop test to be conducted at more force angles and to more comprehensively test the laptop's drop resistance and shock resistance performance.

[0071] In one embodiment, the angle adjustment mechanism includes a hinge plate 32 disposed on the side of the holding plate 31 facing the sliding component 2; the hinge plate 32 has a first hinge pin 321 that is hinged to the sliding component 2, and an arc-shaped slide groove 322 that is adjustablely connected to the sliding component 2.

[0072] Specifically, in combination Figure 3 In further detail, the angle adjustment mechanism is specifically set as a hinge plate 32, and the hinge plate 32 is hinged to the sliding component 2 through the first hinge pin 321 and is adjustablely connected to the sliding component 2 through the arc-shaped slide groove 322. In this way, by adjusting the relative position of the fastening screw in the arc-shaped slide groove 322, the installation angle between the holding plate 31 and the sliding component 2 can be adjusted, which has the beneficial effects of simple structure and convenient adjustment.

[0073] In one embodiment, the lifting assembly 1 further includes a radar ranging module 113 disposed in the lifting member 11; the radar ranging module 113 is used to measure the height information between the lifting member 11 and the bottom surface.

[0074] Specifically, in combination Figure 2To further explain, a radar ranging module 113 is provided in the lifting component 11 for measuring the height information between the lifting component 11 and the bottom surface. The radar ranging module 113 can be electrically connected to the processor in the drop test device. The radar ranging module 113 can further measure the height information of the lifting component 11. When the measured height information exceeds the rated error of the preset drive output height information of the drive motor 12, the processor can compensate and adjust the drive motor 12 according to the actual height information measured by the radar ranging module 113, thereby ensuring that the rising height of the lifting component 11 meets the predetermined test requirements.

[0075] The radar ranging module 113 described above can further measure the height information of the lifting component 11, and further ensure that the lifting height of the lifting component 11 meets the predetermined test requirements.

[0076] In one embodiment, the drop test device further includes a control panel 5, which is equipped with buttons for electrically connecting to the lifting assembly 1 and a processor for electrically connecting to the pad assembly 4.

[0077] Specifically, in combination Figure 2 To further explain, the control panel 5 is equipped with buttons for electrical connection to the lifting assembly 1. These buttons include, but are not limited to, start, pause, reset, preset height increase, and preset height decrease buttons. The processor in the control panel 5 is electrically connected to the pad assembly 4, so that the falling impact load information detected by the pad assembly 4 can be recorded by the processor.

[0078] The aforementioned control panel 5 facilitates the adjustment of drop test parameters and the recording of drop test results.
