For example, in industrial production, these drivers are widely used in various production equipment, machine tools, conveying equipment, and robots. In the field of transportation, DC motor drivers are also widely used in rail transportation, electric vehicles, and other fields. In addition, DC motor drivers also play an important role in home appliances, medical equipment, aerospace, and other fields.

[0003] In order to ensure the stability of the position of the motor driver during use, it is usually necessary to position it for installation. Traditional motor drivers are generally fixed on the bracket by multiple bolts. When installing and disassembling the motor driver, the staff needs to use special tools and tighten the bolts one by one.

[0004] Although the motor driver can be positioned and installed by bolts, the disassembly and assembly efficiency is low. Secondly, if the motor driver is in a vibrating environment, the bolts are easily loosened due to long-term vibration, thereby affecting the stability of the installation. Utility Model Content

To this end, the utility model proposes a motor driver installation structure, which solves the problem that the motor driver bolt installation method is not only inefficient, but also easily affected by vibration and installation stability.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, a mounting structure of a motor driver is provided, comprising a base plate and a frame plate located at the bottom of the motor driver, a step groove for supporting the frame plate is provided on the top of the base plate, and the upper surface of the frame plate is flush with the upper surface of the base plate, and limit members are respectively provided at the four corners of the top of the base plate;

[0007] The stopper includes a movable column and a protrusion, one end of the movable column is rotatably connected to the top of the base plate through a pin shaft, and the lower surface of the other end of the movable column is in contact with the upper surface of the frame plate, the protrusion is vertically connected to the side wall of the movable column near one end, and the protrusion and the movable column are combined into an L-shaped structure;

[0008] A pressure strip is arranged between the two movable columns on the same side, a notch is provided on the upper surface of the protrusion away from the end of the movable column, the end of the pressure strip is engaged with the notch, and an elastic stretching component is installed between the pressure strip and the base plate.

[0009] As a further technical solution of the utility model, the elastic stretching component includes a pull rod installed at the bottom of the pressure strip, a cavity for inserting the pull rod is opened at the top of the base plate, and the bottom end of the pull rod is connected to an annular block slidably connected to the cavity, and a spring is installed between the bottom of the annular block and the lower surface of the cavity.

[0010] As a further technical solution of the utility model, fans are symmetrically installed in the base plate, a dust filter plate is installed at the position of the fan corresponding to the bottom of the step groove, and an inverted U-shaped vent corresponding to the step groove is opened at the bottom of the base plate.

[0011] As a further technical solution of the utility model, the elastic stretching assembly also includes a pull ring, and the pull ring is fixedly installed at the center of the top of the pressure strip.

[0016] 2. In the utility model, the elastic stretching component is used to facilitate the control of the pressure strip to be stretched in the vertical direction. When the movable column is in contact with the top of the frame, the end of the pressure strip is controlled to engage with the notch on the top of the protrusion, so that the position of the movable column cannot be deflected, thereby effectively improving the stability of the installation position. The separation of the control pressure strip from the notch can facilitate the deflection of the movable column and the separation from the top of the frame, thereby facilitating the rapid disassembly and separation of the motor driver and the substrate. In addition, in a vibrating environment, the pressure strip is subjected to the downward pulling force of the elastic stretching component, so that it will not be separated from the notch due to vibration, thereby effectively ensuring the stability of the position of the movable column, so that the installation of the motor driver has good stability.

DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-6 As shown, a mounting structure of a motor driver comprises a substrate 1 and a frame plate 2 located at the bottom of the motor driver. To facilitate heat dissipation inside the motor driver, in this embodiment, the bottom of the motor driver is open, and a step groove 3 for supporting the frame plate 2 is provided on the top of the substrate 1. To ensure the sealing between the notches of the frame plate 2 and the step groove 3, in this embodiment, a rubber sealing strip 16 is provided between the notches of the frame plate 2 and the step groove 3. The rubber sealing strip 16 is circumferentially installed at the edge of the frame plate 2. Fans 11 are symmetrically installed in the substrate 1. The two fans 11 rotate in opposite directions when running. A dust filter plate 12 is installed at the bottom of the step groove 3 corresponding to the position of the fan 11. An inverted U-shaped vent 13 corresponding to the step groove 3 is provided at the bottom of the substrate 1.

[0026] The upper surface of the frame plate 2 is flush with the upper surface of the substrate 1. Limiting members 4 are respectively arranged at the four corners of the top of the substrate 1. The limiting members 4 include a movable column 401 and a protrusion 402. One end of the movable column 401 is rotatably connected to the top of the substrate 1 through a pin shaft, and the lower surface of the other end of the movable column 401 is fitted with the upper surface of the frame plate 2. A stopper 15 is installed on the top of the frame plate 2. The stopper 15 is fitted with the side wall of the movable column 401 away from the end of the protrusion 402. The stopper 15 can play a positioning role, which is convenient for the movable column 401 to quickly reset after deflection. The protrusion 402 is vertically connected to the side wall of the movable column 401 near one end, and the protrusion 402 and the movable column 401 are combined into an L-shaped structure.

[0027] A pressure strip 5 is provided between the two movable columns 401 on the same side, and a notch 6 is provided on the upper surface of the end of the protrusion 402 away from the movable column 401. The end of the pressure strip 5 is engaged with the notch 6. By engaging the pressure strip 5 with the two protrusions 402 on the same side, it is convenient to limit the rotational freedom of the two movable columns 401 on the same side, which is beneficial to improve the stability of the positioning installation, and an elastic stretching component is installed between the pressure strip 5 and the base plate 1;

[0028] The elastic stretching component includes a pull rod 7 installed at the bottom of the pressure strip 5, a cavity 8 for inserting the pull rod 7 is opened at the top of the substrate 1, and the bottom end of the pull rod 7 is connected to a ring block 9 slidably connected to the cavity 8, and a spring 10 is installed between the bottom of the ring block 9 and the lower surface of the cavity 8. The elastic stretching component also includes a pull ring 14, which is fixedly installed at the center of the top of the pressure strip 5.

[0029] When the motor driver is to be separated from the substrate 1, the pressure strip 5 only needs to be pulled up to separate from the notch 6, and the movable column 401 is deflected to make it not fit with the frame plate 2, so that the lower surface of the movable column 401 is pressed against the upper surface of the frame plate 2, and the lower surface of the movable column 401 is pressed against the stop block 15.

[0030] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
