DETAILED DESCRIPTION

[0026] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Embodiment 1

[0028] like Figure 1 - Figure 8 As shown, the utility model proposes an expandable dual-screen portable instrument device, including a computer body, the computer body including a main body 1 and an upper flip cover 2 movably connected to the main body 1, a connecting buckle 17 is provided at the top edge of one side of the main body 1, a rotating rod 18 matching the connecting buckle 17 is provided at one side of the upper flip cover 2 and at a position corresponding to the main body 1, and two display screens 19 are provided on the upper flip cover 2, which are a main screen 1901 and a secondary screen 1902;

[0029] The upper and lower ends of the upper flip cover 2 are provided with cover plates 201 for fixing the screen, and the end surfaces of the cover plates 201 at both ends facing the screen are provided with two mutually parallel first slide grooves 202 and third slide grooves 204 along the length direction, and the middle part between the first slide groove 202 and the third slide groove 204 is also provided with a second slide groove 203 obliquely connecting the first slide groove 202 and the third slide groove 204 at the opposite ends, the main screen 1901 is slidably connected to the first slide groove 202, the auxiliary screen 1902 is arranged in the third slide groove 204, and can slide into the first slide groove 202 through the second slide groove 203, and be displayed side by side with the main screen 1901.

[0030] In the embodiment, the upper and lower side frames of the main screen 1901 are equipped with a long slider 25 for limiting the sliding of the main screen 1901 in the first slide groove 202; the upper and lower side frames of the secondary screen 1902 are equipped with a short slider 26 at one end close to the main screen 1901, and a guide bracket 27 is provided in the middle of the upper and lower side frames of the secondary screen 1902, one end of the guide bracket 27 is movably hinged to the secondary screen 1902, and the other end is slidably connected to the third slide groove 204.

[0031] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when the two display screens 19 are in a folded state, the main screen 1901 is entirely located in the first slide groove 202, and the sub-screen 1902 is entirely located in the third slide groove 204, without interfering with each other; when in use, when the two display screens 19 are unfolded side by side, the main screen 1901 is first slid along the first slide groove 202 to the left side facing the operator, so that only half of the main screen 1901 is located in the first slide groove 202, and at this time, the sub-screen 1902 located in the third slide groove 204 is slid in the opposite direction of the sliding of the main screen 1901. Since the main screen 1901 gives up the space of the first slide groove 202, the second slide groove 203 connects the vacant end of the first slide groove 202 with the other end opposite to the third slide groove 204, and the sub-screen 1902 can The guide bracket 27 gradually passes through the middle section of the inclined second slide groove 203 from one side of the third slide groove 204 and enters the first slide groove 202. Since one end of the guide bracket 27 is movably hinged to the auxiliary screen 1902, and the other end is slidably connected to the third slide groove 204, the end of the guide bracket 27 hinged to the auxiliary screen 1902 slides along the second slide groove 203 together with the auxiliary screen 1902 into the first slide groove 202, and the other end of the guide bracket 27 is always sliding in the third slide groove 204. The short slider 26 slides from the third slide groove 204 through the second slide groove 203 and finally enters the first slide groove 202 along the sliding trajectory of the auxiliary screen 1902. At this time, the main screen 1901 and the auxiliary screen 1902 have completed the unfolded state, and the two screens are displayed side by side.

[0032] In the embodiment, the host 1 is connected to the main screen 1901 and the sub-screen 1902 respectively through multiple communication lines, so as to control the display screen 19 display.

[0033] In an embodiment, Figure 6 , Figure 7 and Figure 8 As shown, a control device is provided in the host 1;

[0034] The control device includes a battery 3 arranged in the host 1, a charge and discharge control board 24 arranged in the host 1 and connected to the battery 3, a controller 4 arranged in the host 1 and connected to the battery 3, an instrument module cage 5 arranged in the host 1, a signal adapter board 6 arranged in the host 1 and connected to the controller 4, an expansion backplane 7 arranged in the host 1 and connected to the controller 4, a plurality of horizontal expansion slots 8 arranged in a vertical column on the outer surface of the host 1 and connected to the expansion backplane 7, an equipment protection compartment door 9 arranged at the bottom of the horizontal expansion slot 8, an expansion module 10 arranged in the horizontal expansion slot 8, an auxiliary puller 11 arranged at one end of the outer side of the expansion module 10, a plurality of cooling fans 12 arranged on the inner side of the host 1, a hard disk compartment cover 13 arranged on the lower surface of the host 1, a power interface 14 arranged on the outer side of the host 1 and at a position corresponding to the battery 3, a heat dissipation hole 15 arranged on the outer side of the host 1 and at a position corresponding to the cooling fan 12, and an external expansion interface 16 arranged on the outer side of the host 1 and connected to the expansion backplane 7.

[0035] Specifically, the horizontal expansion slot 8 is the bus expansion slot of the machine, which is also the main feature of the portable instrument. The expansion slot 8 has three configurations: PXI bus expansion slot, PXIe bus expansion slot, and PXIe hybrid expansion slot (both PXI and PXIe bus modules).

[0036] When configured as a PXI expansion slot, this slot can expand standard PXI or PCI bus module cards. The PXI bus combines the electrical bus characteristics of PCI with the modularity of CompactPCI and the characteristics of the Eurocard mechanical packaging structure. It adds a high-performance synchronization and timing bus for measurement and control applications, allowing PXI modules to support precise time synchronization and triggering between multiple devices, and is suitable for application scenarios that require coordination of multiple devices and signals. When configured as a PXIe expansion slot, the bus speed of this slot is the speed of PCIe gen3×4, and standard PXIe or CPCIe bus module cards can be expanded. When configured as a PXIe hybrid expansion slot, both PXI bus modules and PXIe bus modules can be expanded.

[0037] These three bus expansion slots with different configurations are compatible with standard PXI / PXIe / CompactPCI bus modules. Users can choose the configuration according to the expansion module 10 they need to use. This makes the portable instrument equipment test platform have more functions and application possibilities, realizes more diverse and complex test tasks, and improves test efficiency and flexibility.
