[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0033] The driver provided by the present application can be a servo driver. According to different models, the longest side size of the existing common small servo driver is usually tens of centimeters to several tens of centimeters, so the compact design of the structure of the servo driver is indeed an important content in the production and design process of the servo driver.

[0034] As Figures 1-5As shown, the embodiment of the present application provides a driver, which comprises an outer shell 1, a radiator 2 and a mainboard 3; the outer shell 1 is provided with an assembly opening 102, and the inner wall of the outer shell 1 is provided with a guide structure extending along a first direction; the mainboard 3 is connected to the radiator 2, and the edge of the mainboard 3 can be slidingly matched with the guide structure along the first direction, so that the outer shell 1 can be moved to be assembled and connected with the radiator 2 under the guidance of the mainboard 3; that is, in the whole machine assembly of the driver, the mainboard 3 is first assembled and connected with the radiator 2, and the mainboard 3 is exposed on the side of the radiator 2 facing the assembly opening 102 of the outer shell 1; wherein the surface of the side of the outer shell 1 opposite to the assembly opening 102 is a front surface 101, and the front surface 101 is distributed with a display screen 4, a key 5, a USB interface 6, a double network port 7, a PIN terminal 8, a firewire interface 9, a power terminal 10 and a grounding connection plate 11 electrically connected with the mainboard 3.

[0035] In this way, in the assembly process of the main component structures of the driver, the outer shell 1, the radiator 2 and the mainboard 3, the mainboard 3 is first fixedly connected to the side of the radiator 2 facing the assembly opening 102 of the outer shell 1, then the outer shell 1 is gradually slid under the guidance of the mainboard 3 to the position assembled and connected with the radiator 2, that is, the mainboard 3 and the radiator 2 enter the outer shell 1 through the assembly opening 102 in turn, so that the mainboard 3 also completes the assembly in the outer shell 1. In this way, the mainboard 3 replaces the guide part that should be arranged on the radiator 2 in the assembly process of the radiator 2 and the outer shell, so that when the assembly is completed, it does not interfere with the layout of the electronic elements on the mainboard 3, and the space on the mainboard 3 can be fully utilized, so that the mainboard 3 can be fully laid out in the outer shell 1, which is conducive to further reducing the volume of the whole driver; at the same time, since the mainboard 3 is fully laid out, it is also conducive to the layout of various interactive structures of different functions on the same side of the outer shell 1. The present application realizes that the front surface 101 of the driver is laid out with the display screen 4, the key 5, the USB interface 6, the double network port 7, the PIN terminal 8, the firewire interface 9, the power terminal 10 and the grounding connection plate 11, the front surface 101 satisfies more device layout, the front surface 101 is rich in function integration, so that the extra space occupied by the wiring is just utilized on the unobstructed side of the front surface 101 after wiring, which realizes the miniaturization of the use space, and solves the problem of how to provide sufficient board layout space for the mainboard 3 while considering the miniaturization design of the whole driver and the miniaturization of the use space in the prior art.

[0036] It should be noted that when the outer shell 1 slides to the position assembled with the radiator 2, the clamping can be completed at the same time as the radiator 2, or the clamping is further connected through the fastener; when the outer shell 1 is assembled with the radiator 2, the outer shell 1 can cover the mainboard 3 and the radiator 2 together, the outer shell 1 is arranged on the radiator 2, and the outer shell 1 is provided with a heat dissipation through hole opposite to the radiator 2; or the outer shell 1 completely covers the mainboard 3, and covers part of the radiator 2. The mainboard 3 comprises a circuit board body and a plurality of electronic elements connected to the top surface.

[0037] Regarding the specific form of the guide structure, there are many ways, and in a preferred embodiment, the guide structure is a guide protrusion 103 protruding relative to the inner wall of the outer shell 1, which can support the mainboard 3 and can be slidably connected with the bottom edge of the mainboard 3. The first direction can be horizontal, that is, the mainboard 3 is slidably connected with the outer shell 1 in a flat state.

[0038] In this way, in the thickness direction of the mainboard 3, the guide protrusion 103 is located on one side of the mainboard 3, occupying a small space while forming a support for the mainboard 3, thereby assisting in improving the position stability of the mainboard 3 in the outer shell 1; moreover, the guide protrusion 103 can also serve as a reinforcing rib of the outer shell 1, thereby playing a structure reinforcing role.

[0039] In a preferred embodiment, the guide protrusion 103 extends inward from the assembly opening 102, and the guide protrusion 103 comprises a main body segment and a gradual change segment, the gradual change segment is closer to the assembly opening 102 than the main body segment, and the protruding degree of the gradual change segment relative to the inner wall of the outer shell 1 gradually decreases from the main body segment to the assembly opening 102.

[0040] In this way, since the protruding degree of the local guide protrusion 103 close to the assembly opening 102 is gradually changed, a guide angle design is formed, and the gradual change segment plays a certain avoiding role, which is beneficial to reducing the collision possibility between the outer shell 1 and the mainboard 3 when the assembly opening 102 of the outer shell 1 just reaches the mainboard 3, thereby protecting the mainboard 3.

[0041] Regarding other forms of the guide structure, in another alternative embodiment, the guide structure is a guide protrusion 103 protruding relative to the inner wall of the outer shell 1, and the guide protrusion 103 is provided with two rows in parallel, and in the thickness direction of the mainboard 3, the edge of the mainboard 3 can extend into the two rows of guide protrusions 103. In this way, the guide protrusion 103 is slidably connected with the top edge and the bottom edge of the mainboard 3, and the two rows of guide protrusions 103 form a double-sided limiting effect on the mainboard 3, so that the mainboard 3 is less affected by stress whether it is standing or flat.

If the outer shell 1 is locally thickened, it is also feasible to provide a guide groove on the inner wall by subtractive machining.

[0044] In a specific embodiment, when the guide structure is in the form of the guide protrusion 103, the guide structure is continuously or discontinuously distributed along the first direction, and the two cases are selected according to the specific design; the continuous distribution of the guide structure can provide continuous guidance, so that the sliding fit between the outer shell 1 and the main board 3 is more stable and reliable; and the discontinuous distribution of the guide structure can play a certain weight reduction role, which conforms to the design trend of light weight.

[0045] When the guide structure is in the form of the guide groove, the guide structure needs to be continuously distributed along the first direction.

[0046] In a preferred embodiment, the extension direction of the longest side of the main board 3 is perpendicular to the first direction, and in the extension direction of the longest side of the main board 3, the opposite side edges of the main board 3 are close to the inner wall of the outer shell 1. In this way, the extension direction of the longest side of the main board 3 is parallel to the long side direction of the front surface 101 of the outer shell 1, and on the basis of meeting the miniaturization design requirement of the drive, the front surface 101 layout also maximizes the benefit of the distribution of the main board 3, and has the largest possible front surface 101 layout space.

[0047] Further, it is preferred that the space between the top surface of the main board 3 and the outer shell 1 is much larger than the space between the bottom surface of the main board 3 and the outer shell 1, so that the space in the outer shell 1 is as much as possible to be occupied by the electronic elements on the top surface of the main board 3.

[0048] In a preferred embodiment, a notch groove 104 extending along the first direction is provided at the corner position of the outer shell 1, so that at least part of the guide structure is exposed; and a connecting part 201 extending along the first direction is provided on the heat sink 2, and the connecting part 201 can be complementarily spliced with the notch groove 104.

[0049] In this way, especially in the embodiment of the guide protrusion 103, the notch groove 104 can be provided above the guide structure, and the notch groove 104 can expose part of the guide protrusion 103, so that the guide protrusion 103 can be positioned by the related sensing structure in the automatic assembly operation, so as to promote the accurate guiding and assembly between the outer shell 1 and the main board 3, and facilitate the automatic assembly design of the drive.

[0050] Regarding the front face 101 layout of the driver, in a specific embodiment, the front face 101 is narrow and long, the display screen 4, the button 5, the USB interface 6, the double network port 7, the PIN terminal 8, the firewire interface 9, the power terminal 10 and the grounding connection plate 11 are arranged along the long edge direction of the front face 101 in sequence; when the use state of the driver is that the front face 101 is vertically placed, the display screen 4 is at the uppermost.

[0051] The display screen 4 can be a digital display screen 4 and the like, the button 5 includes multiple and is used for interacting with the display screen 4, the USB interface 6 can be a Type-C interface, the PIN terminal 8 can be 2*6 specifications, the firewire interface 9 is also an IEEE1394 interface, and the power terminal 10 can be a 9pin power terminal 10.
