Description

Technical Field

[0001] This utility model relates to the field of generator technology, specifically a rotating rectifier half-bridge module. Background Technology

[0002] A rotating rectifier half-bridge module is an electronic device used for brushless excitation rectification of generators. It typically consists of multiple power transistors and diodes forming a half-bridge structure. During operation, the module controls the conduction state of the power transistors and diodes based on the AC waveform generated by the generator and control signals, converting the AC power into a stable DC output to supply the generator's excitation system. By using a rotating rectifier half-bridge module, precise control and stable power supply to the generator's excitation system can be achieved, thereby improving the generator's operating efficiency and performance. In existing rotating rectifier half-bridge modules, the power transistors and diodes are fixed by bolt connections. If a power transistor or diode fails later, the corresponding power transistor or diode needs to be replaced. The bolt removal and subsequent bolt re-fixing operations are time-consuming. Therefore, we propose a rotating rectifier half-bridge module. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a rotating rectifier half-bridge module. This device uses limiting elements to simultaneously squeeze and limit the power transistors and diodes in the rotating rectifier half-bridge module, eliminating the need for bolt fixing. The subsequent maintenance and replacement of the power transistors and diodes in the device are convenient, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotating rectifier half-bridge module, including a substrate and a mounting limiting mechanism;

[0005] Substrate: It has an outer shell on its upper side, and six evenly distributed limiting cylinders are provided on the bottom wall of the outer shell. Diodes are inserted into the three limiting cylinders near the inner arc wall of the outer shell, and power transistors are inserted into the three limiting cylinders near the outer arc wall of the outer shell.

[0006] The installation limiting mechanism includes an arc-shaped slide bar and installation limiting seats. The arc-shaped slide bar is slidably connected to an arc-shaped groove on the upper side of the housing. Six evenly distributed installation limiting seats are provided on the upper side of the arc-shaped slide bar. The upper side of the power transistor and the upper side of the diode are in contact with the lower side of the adjacent installation limiting seat. This device simultaneously squeezes and limits the installation of the power transistor and diode in the rotating rectifier half-bridge module through limiting elements, eliminating the need for bolt fixing. This facilitates the maintenance and replacement of the power transistor and diode in the device later.

[0007] Furthermore, the mounting limiting mechanism also includes arc-shaped chamfers, which are respectively formed on the upper outer edge of the power transistor and diode and the lower outer edge of the mounting limiting seat, to facilitate horizontal contact movement between the power transistor and diode and the corresponding mounting limiting seat.

[0008] Furthermore, the installation limiting mechanism also includes an arc-shaped telescopic rod and a spring. The arc-shaped telescopic rod and the spring are disposed between the right side of the arc-shaped slide bar and the arc-shaped slide groove. The spring is movably connected to the outer end of the arc-shaped telescopic rod. The arc center of both the fixed end and the telescopic end of the arc-shaped telescopic rod coincides with the arc center of the arc-shaped slide groove. The compression force of the spring prevents the arc-shaped slide bar from sliding along the arc-shaped slide groove during the use of the device.

[0009] Furthermore, the installation limiting mechanism also includes an adjustment knob, which is located on the upper side of the arc-shaped slide bar to facilitate applying external force to the arc-shaped slide bar within the rotating rectifier half-bridge module.

[0010] Furthermore, ten evenly distributed heat dissipation gap grooves are provided on the outer side of the limiting cylinder, and a heat dissipation filter is installed in the rear side wall of the outer shell to dissipate heat from the power transistors and diodes.

[0011] Furthermore, all the limiting cylinders are made of copper, which improves the heat dissipation effect of the device on the power transistors and diodes by increasing the thermal conductivity of the limiting cylinders themselves.

[0012] Furthermore, countersunk mounting holes are provided at both the left and right ends of the upper side of the substrate to facilitate the installation of the rotating rectifier half-bridge module onto the motor.

[0013] Furthermore, the bottom wall of each limiting cylinder is provided with a rubber anti-slip pad, which increases the contact friction between the power transistor and the corresponding diode, thereby preventing rotational sliding between the power transistor and the diode and the corresponding limiting cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This rotating rectifier half-bridge module has the following advantages:

[0015] When using the rotating rectifier half-bridge module, the device can simultaneously squeeze and limit the power transistors and diodes inside the rotating rectifier half-bridge module through the arc-shaped slider, mounting limit seat, arc-shaped chamfer, arc-shaped telescopic rod, spring, adjustment knob and rubber anti-slip pad, without the need for bolt fixing, and the subsequent maintenance and replacement of the power transistors and diodes inside the device is convenient.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a rotating rectifier half-bridge module, including a base plate 1 and a mounting limiting mechanism 6;

[0023] Substrate 1: It has an outer shell 2 on its upper side. The bottom wall of the outer shell 2 has six evenly distributed limiting cylinders 3. The three limiting cylinders 3 near the inner arc wall of the outer shell 2 are all inserted with diodes 5, and the three limiting cylinders 3 near the outer arc wall of the outer shell 2 are all inserted with power transistors 4. Ten evenly distributed heat dissipation gap grooves 7 are opened on the outer side of the limiting cylinders 3. A heat dissipation filter 8 is installed in the rear side wall of the outer shell 2. The limiting cylinders 3 are all made of copper. The upper left and right ends of the substrate 1 are provided with countersunk mounting holes 9. The rotating rectifier half-bridge module is installed in the corresponding position in the motor through the countersunk mounting holes 9 and countersunk bolts. During the operation of the rotating rectifier half-bridge module, the heat generated by the power transistors 4 or diodes 5 is diffused outward through the heat dissipation gap grooves 7 and the heat dissipation filter 8, thereby improving the heat dissipation effect of the device itself and avoiding poor heat dissipation effect of power transistors 4 and diodes 5 in a closed environment. At the same time, the limiting cylinders 3 are made of copper metal. By improving the heat transfer efficiency of the limiting cylinders 3 themselves, the heat dissipation effect of power transistors 4 or diodes 5 is further improved.

[0024] The mounting limiting mechanism 6 includes an arc-shaped slide bar 61 and mounting limiting seats 62. The arc-shaped slide bar 61 is slidably connected to an arc-shaped groove on the upper side of the housing 2. Six evenly distributed mounting limiting seats 62 are provided on the upper side of the arc-shaped slide bar 61. The upper side of the power transistor 4 and the upper side of the diode 5 are in contact with the lower side of the adjacent mounting limiting seats 62. The mounting limiting mechanism 6 also includes an arc-shaped chamfer 63, which is respectively opened on the upper outer edge of the power transistor 4 and the diode 5 and the lower outer edge of the mounting limiting seat 62. The mounting limiting mechanism 6 also includes an arc-shaped telescopic rod 64 and a spring 65, which are arranged on the right side of the arc-shaped slide bar 61 and the arc-shaped groove 62. Between the shaped grooves, the spring 65 is movably sleeved with the outer end of the arc-shaped telescopic rod 64. The arc center of both the fixed end and the telescopic end of the arc-shaped telescopic rod 64 coincides with the arc center of the arc-shaped groove. The installation limiting mechanism 6 also includes an adjustment knob 66, which is located on the upper side of the arc-shaped slide bar 61. The bottom wall of the limiting cylinder 3 is provided with rubber anti-slip pads 10. When using the rotary rectifier half-bridge module, the spring 65 inside the device is always in a contracted state. First, the operator moves the adjustment knob 66 ​​to the right to make it drive the arc-shaped slide bar 61 to slide clockwise along the arc-shaped groove, so that the arc-shaped slide bar 61 drives the installation limiting seat 62 to be vertically misaligned with the upper opening of the adjacent limiting cylinder 3. During this process, the arc-shaped telescopic rod 65... The telescopic end of 4 and spring 65 retract again, and then power transistor 4 and diode 5 are inserted into the corresponding limiting cylinders 3 respectively. The lower sides of power transistor 4 and diode 5 are in contact with the upper side of the adjacent rubber anti-slip pad 10. Then, the adjustment knob 66 ​​is turned to the left, so that the arc-shaped slide bar 61 drives the mounting limiting seat 62 to slide counterclockwise and reset along the arc-shaped slide groove. At this time, the arc-shaped chamfer 63 of the lower edge of the mounting limiting seat 62 is pressed into contact with the arc-shaped chamfer 63 of the upper edge of the corresponding power transistor 4 or diode 5, thereby pressing the power transistor 4 or diode 5 into the corresponding limiting cylinder 3 and vertically limiting them. As the power transistor 4 or diode 5 goes deeper into the corresponding limiting cylinder 3, the power transistor 4 or diode 5 is pressed into the corresponding limiting cylinder 3. The contact friction between the limiting cylinder 3, the power transistor 4 or diode 5 and the adjacent rubber anti-slip pad 10 is increased. This contact friction is used to limit the rotation of the power transistor 4 or diode 5 within the corresponding limiting cylinder 3, thereby achieving quick installation and complete limiting of the power transistor 4 and diode 5. The compression force of the spring 65 prevents the arc-shaped slide bar 61 from sliding along the arc-shaped groove during the use of the device. The device simultaneously squeezes and limits the installation of the power transistor 4 and diode 5 in the rotating rectifier half-bridge module through the limiting element, eliminating the need for bolt fixing. The maintenance and replacement of the power transistor 4 and diode 5 in the device are convenient in the later stages.

[0025] The working principle of the rotary rectifier half-bridge module provided by this utility model is as follows: When using the rotary rectifier half-bridge module, the internal spring 65 is always in a contracted state. First, the operator moves the adjustment knob 66 ​​to the right, causing the arc-shaped slide bar 61 to slide clockwise along the arc-shaped slide groove. This causes the arc-shaped slide bar 61 to cause the mounting limit seat 62 to be vertically misaligned with the upper opening of the adjacent limit cylinder 3. During this process, the telescopic end of the arc-shaped telescopic rod 64 and the spring 65 contract again. Then, the power transistor 4 and diode 5 are respectively inserted into the corresponding limit cylinders. Inside the positioning cylinder 3, the lower sides of the power transistor 4 and diode 5 are in contact with the upper side of the adjacent rubber anti-slip pad 10. Then, the adjustment knob 66 ​​is turned to the left, causing the arc-shaped slide bar 61 to slide counterclockwise along the arc-shaped slide groove, driving the mounting limit seat 62 to reset. At this time, the arc-shaped chamfer 63 on the lower edge of the mounting limit seat 62 is pressed against the arc-shaped chamfer 63 on the upper edge of the corresponding power transistor 4 or diode 5, thereby pressing the power transistor 4 or diode 5 into the corresponding limiting cylinder 3 and vertically limiting them. Diode 5 is inserted into the corresponding limiting cylinder 3, increasing the contact friction between power transistor 4 or diode 5 and the adjacent rubber anti-slip pad 10. This contact friction limits the rotation of power transistor 4 or diode 5 within the corresponding limiting cylinder 3, thus enabling quick installation and complete limiting of power transistor 4 and diode 5. The compression force of spring 65 prevents the arc-shaped slide bar 61 from sliding along the arc-shaped groove during use, facilitating the maintenance and replacement of power transistor 4 or diode 5 later. Subsequently, the rotating rectifier half-bridge module is installed into the corresponding position inside the motor using countersunk bolts through the countersunk mounting hole 9. During the operation of the rotating rectifier half-bridge module, the heat generated by power transistor 4 or diode 5 is diffused outward through the heat dissipation gap groove 7 and heat dissipation filter 8, thereby improving the heat dissipation effect of the device itself and preventing poor heat dissipation of power transistor 4 and diode 5 in a closed environment. At the same time, the limiting cylinder 3 is made of copper metal, which improves the heat transfer efficiency of the limiting cylinder 3 itself, further enhancing the heat dissipation effect of power transistor 4 or diode 5.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
