[0039] In combination with the drawings, Figures 1-6 As shown in the drawings, according to the embodiment of the utility model, an electric control box is provided, which comprises a box body 100, a first separation structure 10 and a sealing structure. The first separation structure 10 separates the inside of the box body 100 into a first cavity 21 and a second cavity 22. The first cavity 21 has mounting positions for mounting electronic components. The second cavity 22 is provided with a heat dissipation structure for dissipating heat from the electronic components. The sealing structure is used to improve the sealing performance of the first cavity 21.
[0040] In the above example, by designing the sealing structure, the first cavity 21 is designed as a working cavity with certain sealing performance, for arranging various electronic components. By designing the heat dissipation structure, the second cavity 22 is designed as a heat dissipation cavity for dissipating heat from the electronic components in the first cavity 21. The separation of the working cavity and the heat dissipation cavity effectively improves the IP protection level of the working cavity, i.e. the first cavity 21, and improves the protection performance of the electronic components in the first cavity 21.
[0041] Among them, the electric control box of the utility model can ensure the improvement of the protection level of the whole machine while ensuring the heat dissipation of the whole machine, and avoid the influence of external dust and liquid in harsh environment.
[0042] In some embodiments, as Figures 4-5As shown, the first cavity 21 has a first side wall 201 and a second side wall 202. The first side wall 201 is located on a first side plate 203 of the box 100. The second side wall 202 is located on a second side plate 204 of the box 100. The first side plate 203 is connected with the second side plate 204, and a gap 205 is formed at the joint of the first side wall 201 and the second side wall 202. The sealing structure includes a sealing member 18, which is filled in the gap 205 to seal the gap 205.
[0043] In the above example, the sealing structure seals the gap 205 at the joint of the first side wall 201 and the second side wall 202 by the sealing member 18, which prevents water from entering the joint of the first side wall 201 and the second side wall 202, thereby improving the sealing performance of the first cavity 21.
[0044] In some embodiments, the sealing member 18 can be dustproof and waterproof cotton or the like.
[0045] In some embodiments, as shown in FIG. 1, the first side plate 203 and the second side plate 204 are connected by a fastener at the joint of the first side wall 201 and the second side wall 202. Figures 4-5
[0046] In the above example, the first side plate 203 and the second side plate 204 clamp the sealing member 18, which can compact the sealing member 18 and improve the sealing effect of the sealing member 18 on the gap 205.
[0047] In some embodiments, the sealing member 18 is also fixedly attached to the wall of the gap 205 to improve the connection stability of the sealing member 18.
[0048] In some embodiments, the fastener can be a screw or the like.
[0049] In some embodiments, as shown in FIG. 1, the outer wall of the first cavity 21 has a mounting position for mounting a power switch. The sealing structure includes a waterproof cover 5 for covering the power switch. Figure 1
[0050] In the above example, the sealing structure covers the power switch by the waterproof cover 5, which prevents water from entering the first cavity 21 at the power switch, thereby improving the sealing performance of the first cavity 21.
[0051] In some embodiments, the power switch can be an air switch. The power switch functions to turn on / off the whole machine, which is equivalent to a circuit switch, and is connected with the internal circuit of the upper cavity.
[0052] In some embodiments, as shown in Figure 1 The sealing structure includes a wire passing hole 71 arranged on the cable passing wall 7. The cable passing wall 7 is made of elastic material. The wire passing hole 71 has a first state of closing under the elastic force of the elastic material and a second state of opening under the extrusion of the cable when the wire passes through.
[0053] In the above example, when the wire passing hole 71 does not pass through the wire, the wire passing hole 71 is closed under the elastic force of the elastic material, so as to prevent water from passing through; when the wire passing hole 71 passes through the wire, the wire passing hole 71 is extruded by the cable under the action of the elastic material, so that the hole wall of the wire passing hole 71 is attached to the cable, thereby preventing water from passing through. The sealing structure seals the wire outside the first cavity 21 through the wire passing hole 71, which can prevent water from entering the first cavity 21 at the wire outside, thereby improving the sealing performance of the first cavity 21.
[0054] In some embodiments, the elastic material can be a waterproof sponge, and the number of wire passing holes 71 can be two or more.
[0055] For the structure of the entire first cavity 21, the sealing member 18, the waterproof cover 5 and the wire passing hole 71 cooperate to waterproof and dustproof the devices connected with the outside of the first cavity 21, and in addition, the electrical terminals in the first cavity 21 are waterproof and dustproof terminals, so as to achieve waterproof connection between the first cavity 21 and the outside, thereby achieving the purpose of waterproof and dustproof of the first cavity 21.
[0056] In order to realize the function of the heat dissipation structure, in some embodiments, the heat dissipation structure can include a first ventilation hole 60 and a second ventilation hole 61. The first ventilation hole 60 is arranged on the first partition structure 10 to communicate the first cavity 21 and the second cavity 22. The second ventilation hole 61 is arranged on the outer side wall of the second cavity 22 to communicate the inside of the second cavity 22 with the outside of the box body 100.
[0057] In the above example, the first cavity 21 can be communicated with the outside of the box body 100 through the first ventilation hole 60 and the second ventilation hole 61, which is conducive to the flow of air between the first cavity 21 and the outside of the box body 100, thereby realizing the heat dissipation of the electronic components in the first cavity 21.
[0058] In some embodiments, as shown in Figure 3As shown, the aforementioned heat dissipation structure can comprise a heat sink 20, which is used to contact the electronic components to dissipate heat from the electronic components.

[0060] In some embodiments, the aforementioned heat sink 20 can be a fin-type heat sink or an aluminum profile heat sink.
[0061] In some embodiments, as shown, Figure 3 As shown, the aforementioned heat dissipation structure can comprise a heat dissipation fan 9, which can accelerate air flow when started and help dissipate heat from the electronic components in the first cavity 21.
[0062] In some embodiments, as shown, Figure 3 As shown, the aforementioned heat dissipation fan 9 and the aforementioned second vent hole 61 can be arranged on opposite sides of the second cavity 22, so that the second cavity 22 forms an inlet and outlet air duct, which helps to improve the heat dissipation performance.
[0063] In some embodiments, as shown, Figure 6 As shown, the aforementioned electric control box can further comprise a second partition structure 11, which is used to separate the first cavity 21 into a strong current cavity 21a and a weak current cavity 21b, and the second partition structure 11 is further provided with a wiring hole 111 that communicates the strong current cavity 21a and the weak current cavity 21b. The wiring hole 111 is used for wiring between the strong current cavity 21a and the weak current cavity 21b.
[0064] In the aforementioned example, the first cavity 21 is separated into the strong current cavity 21a and the weak current cavity 21b by the second partition structure 11, so that a layout of strong and weak current separation is formed in the first cavity 21, which can ensure that the weak current devices are not disturbed by the strong current devices during operation.
[0065] In some embodiments, the aforementioned first partition structure 10 can comprise a first partition plate, which separates the box 100 into the first cavity 21 and the second cavity 22 by the first partition plate. The aforementioned second partition structure 11 can comprise a second partition plate, which separates the first cavity 21 into the strong current cavity 21a and the weak current cavity 21b by the second partition plate. The electric control box forms a layered design by the first partition plate and the second partition plate.
[0066] In some embodiments, the aforementioned first partition plate and the second partition plate can both be a combination plate composed of two or more partition plates.
[0067] In some embodiments, the aforementioned box 100 adopts an external integrated structure, and is compact. The aforementioned box 100 can reach a desktop level box. The desktop level box refers to a compact overall structure, and the length and the width are greater than the height, and the desktop level box is flat, and does not need to occupy a large space, and can be directly stored in an ordinary desktop or a drawer.
[0068] In some embodiments, as shown in Figures 1-2 The aforementioned box 100 can be an overall peripheral structure formed by fixing and connecting a top cover plate 1, a window plate 2, a heat dissipation grid plate 6, a bottom side plate 3, a terminal plate metal component 4 and a rear cover plate 8 through fasteners such as screws, press-in nuts and the like, and the box 100 is mainly made of a metal component material.
[0069] In some embodiments, the utility model also provides a robot driving and control integrated machine, which comprises the electric control box of any one of the above. Since the robot driving and control integrated machine adopts the electric control box, the first cavity 21 is designed as a certain sealed working cavity for arranging various electronic components through the sealing structure, and the second cavity 22 is designed as a heat dissipation cavity for dissipating heat of the electronic components in the first cavity 21 through the heat dissipation structure, so that the working cavity, that is, the first cavity 21, is effectively improved in IP protection level, and the protection performance of the electronic components in the first cavity 21 is improved.
[0070] In some embodiments, when the heat dissipation structure comprises a heat sink 20 for contacting the electronic components to dissipate heat of the electronic components, the electronic components comprise a driver module 16, and the electronic components contact the heat sink 20 through the driver module 16.
[0071] In the above example, since the driver module 16 has a large amount of heat, contacting the heat sink 20 with the electronic components with a large amount of heat helps to solve the heat dissipation problem.
[0072] In some embodiments, as shown in Figure 6 The aforementioned electronic components can comprise a motion controller assembly 12, an alternating current contactor assembly 13, a switching power supply module 14, a transformer module 15 and a filter module 17. The aforementioned first cavity 21 can be an upper cavity, and the second cavity 22 can be a lower cavity.
[0073] The motion controller assembly 12, the alternating current contactor assembly 13, the switching power supply module 14, the transformer module 15 and the filter module 17 are circuit modules for driving and controlling the robot to normally operate.
[0074] As shown in Figure 4As shown, the robot drive control all-in-one machine further comprises a braking resistor 19 arranged in the second cavity 22.
[0075] In some embodiments, the braking resistor 19 can be a cement resistor or the like.
[0076] The structure of the robot drive control all-in-one machine effectively solves the contradiction between the heat dissipation problem and the protection problem, forms a high-protection drive control all-in-one machine, and has a simple and compact structure.
