For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1 to 4 As shown, the chassis provided by the embodiment of the present invention includes: a PCB chassis 100, a peripheral frame 200 and multiple peripheral side panels 300; the PCB chassis 100 is installed inside the peripheral frame 200, and the multiple peripheral side panels 300 are arranged around the outer periphery of the PCB chassis 100 and installed on the peripheral frame 200; the PCB chassis 100 has a first side wall 110 and a second side wall 120 arranged opposite to each other, and at least one of the first side wall 110 and the second side wall 120 is fixedly installed with an adapter 400, which is used to connect to the robot arm.

[0030] Specifically, the outer frame 200 is sleeved around the periphery of the PCB chassis 100, and the PCB chassis 100 is fixed to the interior of the outer frame 200 via bolts. Multiple outer side panels 300 are arranged around the periphery of the PCB chassis 100, with spaces formed between the PCB chassis 100, the outer frame 200, and each outer side panel 300, thereby protecting the PCB chassis 100 within. It will be appreciated that the outer frame 200 and the multiple outer side panels 300 together form a box that sleeves around the outside of the PCB chassis 100. A gap is provided between the inner side of the box and the PCB chassis 100, facilitating the installation of components and heat dissipation. In addition, the PCB chassis 100 has a top wall and a bottom wall arranged in parallel and spaced apart, a front wall 130 and a rear wall 140 arranged in parallel and spaced apart, and a first side wall 110 and a second side wall 120 arranged in parallel and spaced apart. The middle part of the first side wall 110 and the middle part of the second side wall 120 are both fixed with adapters 400 by bolts. Mounting through holes are provided on the outer side panel 300 opposite to the first side wall 110 and the outer side panel 300 opposite to the second side wall 120. The positions of the mounting through holes correspond to the positions of the corresponding adapters 400 to facilitate the passage of the robotic arm.

[0031] An adapter 400 for connecting to a robotic arm is provided on the PCB chassis 100, so that the robotic arm can act on the PCB chassis 100 without the need for the peripheral frame 200 and the peripheral side panels 300 to support the robotic arm. As a result, the peripheral frame 200 and the peripheral side panels 300 can be made of lightweight materials, such as an aluminum frame and aluminum sheet metal, thereby achieving the purpose of reducing the overall weight of the chassis.

[0032] The PCB chassis 100 also has a front wall 130 and a rear wall 140 that are arranged opposite to each other. The chassis also includes an electrical component module 500, which is installed on the rear wall 140. One of the peripheral side panels 300 is arranged relative to the rear wall 140 and is detachably connected to the peripheral frame 200.

[0033] Specifically, the front wall 130 and the rear wall 140 are both arranged adjacent to the first side wall 110 and the second side wall 120. A mounting structure for mounting the electrical component module 500 is provided on the rear wall 140. The mounting structure is provided at the lower end portion of the rear wall 140. The mounting structure can be specifically provided as a support frame or a support protrusion, etc. A plurality of electrical components are integrated together to form the electrical component module 500. After integration, it is convenient to install. The electrical component module 500 is mounted on the mounting structure by screws. The peripheral side panel 300 opposite to the rear wall 140 is detachably mounted on the peripheral frame 200 by bolts, thereby protecting the electrical component module 500 mounted on the rear wall 140. When the electrical component module 500 needs to be maintained, the peripheral side panel 300 can be removed from the peripheral frame 200 to facilitate maintenance of the electrical component module 500.

[0034] During the operation of the board installed in the PCB chassis, a lot of heat will be generated. In order to avoid affecting the efficiency of the board, it is necessary to promptly dissipate the heat of the board through air cooling or water cooling. In one embodiment of the present invention, water cooling is used inside the chassis to dissipate heat. Figure 4 As shown, the chassis also includes a water cooling module 600, which is mounted on the rear wall 140 and is used to dissipate heat from the boards installed within the PCB chassis 100. Specifically, the water cooling module 600 is mounted to the rear wall 140 of the PCB chassis 100 via bolts. The water cooling module 600 is connected to an external refrigerant and directly contacts the boards through the water cooling plates within the water cooling module 600. This arrangement allows the refrigerant to deliver cooling water to the water cooling module 600, which then flows into the water cooling plates to remove heat from the boards, thereby cooling the boards. The water cooling module 600 is used to cool the boards. Compared with air cooling, the space occupied by the water cooling module 600 is smaller than that occupied by a fan, which helps save space inside the chassis and reduces the overall weight of the chassis. In addition, the water cooling module 600 is installed on the rear wall 140 of the PCB chassis 100, and the peripheral side panels 300 opposite the rear wall 140 are detachably connected to the peripheral frame 200, which facilitates maintenance of the water cooling module 600. In addition, no electrical components are arranged on the front wall 130 of the PCB chassis 100, which can facilitate natural convection heat dissipation.

[0035] It should be noted that there is no power supply or other components inside the chassis. The electricity required for the operation of the electrical components inside the chassis comes from the external electrical cabinet. That is, the power supply and other components originally installed in the chassis are installed in an electrical cabinet that is compatible with the chassis. This arrangement facilitates the installation and maintenance of components such as the power supply, and also facilitates the compact layout of the chassis, reducing the size of the chassis, and reducing the weight and footprint of the chassis.

[0036] like Figure 5As shown, the water cooling module 600 includes, in addition to the water cooling plate arranged inside the PCB chassis 100, a water inlet pipe 610, a water outlet pipe 620 and a bus 630. The bus 630 is installed on the PCB chassis 100 and is connected to the water cooling plate. The water inlet pipe 610 and the water outlet pipe 620 are respectively connected to the bus 630.

[0037] Specifically, the busbar 630 is rectangular in shape, with the water inlet pipe 610 and the water outlet pipe 620 both mounted on the top wall of the busbar 630 and in communication with the busbar 630. The water cooling plate is provided with a water inlet and a water outlet, which are respectively connected to the liquid outlet and liquid inlet holes on the busbar via pipes. The water cooling plate is in contact with the boards within the PCB chassis 100. Two through-holes are provided on the peripheral side panel 300, which faces the rear wall 140. The end of the water inlet pipe 610, which is remote from the busbar 630, extends out of the chassis through one through-hole, while the end of the water outlet pipe 620, which is remote from the busbar 630, extends out of the chassis through the other through-hole, allowing the water inlet pipe 610 and the water outlet pipe 620 to communicate with an external refrigerant machine via pipes. With this setup, the refrigerant machine delivers refrigerant (such as cold water) to bus 630 via a pipeline. The refrigerant then flows through the outlet of bus 630 into the water-cooled plate. The refrigerant in the water-cooled plate exchanges heat with the boards, removing heat from the boards. The refrigerant then flows back through the water outlet of the water-cooled plate and the inlet of bus 630, returning to bus 630 and further to the refrigerant machine for cooling. The chassis achieves excellent heat dissipation using only water cooling, eliminating the need for fan modules for air cooling.

[0038] The chassis further includes a control panel 700 , which is mounted on the front wall 130 . One of the peripheral side panels 300 is spaced apart from the front wall 130 and is detachably connected to the peripheral frame 200 .

[0039] Specifically, a control panel mounting area is provided at the lower end of the front wall 130. The control panel 700 is located in this mounting area and is mounted to the front wall 130 via screws. The peripheral side panels 300, which are opposite the front wall 130, are detachably connected to the peripheral frame 200 via bolts, providing protection for the control panel 700 mounted on the front wall 130. When maintenance on the control panel 700 is required, the peripheral side panels 300 can be removed from the peripheral frame 200, facilitating access.

[0040] Optionally, the front wall 130 is provided with a vent 131 , and the peripheral side panel 300 opposite to the front wall 130 and the peripheral side panel 300 opposite to the rear wall 140 are both provided with multiple ventilation holes 310 , and the vent 131 and the ventilation holes 310 are both connected to the interior of the PCB chassis 100 .

[0041] Specifically, the interior of the PCB chassis 100 is hollow, and both the front wall 130 and rear wall 140 of the PCB chassis 100 are flat support frames with multiple rows and columns of through holes. The control board 700 is smaller in planar dimensions than the front wall 130 and is mounted to the lower end of the front wall 130. No other electrical components are mounted on the upper end of the front wall 130, thus forming a ventilation opening 131 at the upper end of the front wall 130.

[0042] The peripheral side panels 300 opposite the front wall 130 and the peripheral side panels 300 opposite the rear wall 140 are each provided with a plurality of ventilation holes 310, arranged in multiple rows and columns. External air can enter the chassis through the ventilation holes 310, and internal air can also be discharged from the chassis through the ventilation holes 310, thereby removing heat from the chassis. Because the front wall 130 and the rear wall 140 are spaced apart relative to each other, air can form convection between the front wall 130 and the rear wall 140, and flow out through the corresponding peripheral side panels 300. Ventilation openings 131 are formed at the upper end of the front wall 130, increasing the ventilation area, thereby facilitating natural convection and improving heat dissipation efficiency.

[0043] The chassis further includes a gyroscope, which is mounted on the control board 700. Specifically, the gyroscope is fixedly mounted on the control board 700, and the mounting position is parallel to the horizontal position of the chassis. The gyroscope is used to sense the mounting position of the chassis, thereby improving the accuracy of chassis installation.

[0044] The chassis further includes a plurality of circuit boards, and a protective cover 810 is provided on the outside of each of the circuit boards.

[0045] Specifically, a plurality of circuit boards are provided on the PCB chassis 100, such as Figure 6 As shown, multiple protective covers 810 are provided, and the multiple protective covers 810 are provided one-to-one with multiple circuit boards. Each protective cover is provided outside the corresponding circuit board and is detachably connected to the peripheral frame 200 by bolts. Each protective cover 810 shields the corresponding circuit board, thereby controlling the overflow of electromagnetic radiation.

[0046] The peripheral side plate 300 is provided with through holes for bolt installation.

[0047] Compared with the chassis in the prior art, the chassis provided by the embodiment of the present invention eliminates the power supply and some electrical components and places them in an external electrical cabinet, thereby facilitating the installation and maintenance of the power supply and electrical components. In addition, the chassis layout can be made more compact, thereby reducing the size of the chassis, reducing the weight, and reducing the floor space. In addition, if Figure 6As shown, the chassis provided by the embodiment of the present invention also includes a backplane fixing plate 820, which is installed on the top of the outer frame 200. Compared with the chassis in the prior art, the size of the backplane fixing plate 820 is reduced, thereby reducing the overall size of the chassis.

[0048] In one embodiment, Figures 1 to 4 As shown, the chassis provided by the embodiment of the present invention also includes a hollow cover body 900 arranged in an annular shape. The hollow cover body 900 extends along one end of the peripheral frame 200, and the cross-sectional area of ​​the central hole cover body is larger than the cross-sectional area of ​​the peripheral frame 200. Specifically, the hollow cover body 900 is formed by a plurality of docking side panels connected in sequence, and the plurality of docking side panels can be detachably connected to the top of the peripheral frame 200 and are distributed at intervals along the circumference of the peripheral frame 200. The cross-sectional size of the area enclosed by the plurality of peripheral side panels 300 is larger than the cross-sectional size of the area enclosed by the plurality of peripheral side panels 300. Such an arrangement makes the wiring space on the backplane fixing plate 820 larger, which facilitates wiring operation and maintenance. Preferably, the hollow cover body 900 and the peripheral side panels are both made of sheet metal.

[0049] The testing machine provided by the embodiment of the present invention includes the above-mentioned chassis.

[0050] Specifically, the test machine provided in this embodiment of the utility model further includes a robotic arm, which is connected to an adapter 400 via bolts, thereby mounting the robotic arm on the PCB chassis 100. The adapter 400 provided on the PCB chassis 100 for connection to the robotic arm allows the robotic arm to act on the PCB chassis 100 without requiring the peripheral frame 200 and peripheral side panels 300 to support the robotic arm. This allows the peripheral frame 200 and peripheral side panels 300 to be made of lightweight materials, such as an aluminum frame and aluminum sheet metal, thereby reducing the overall weight of the chassis.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
