DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: A fast response voltage regulator for a new energy vehicle, see Figure 1-Figure 5 and Fig.13 As shown, it includes a motor housing 1, a voltage regulator housing 2, a mounting block 201, an inductor chip 3, a potentiometer 4, a capacitor 5, a circuit board 6 and a wiring port 7. The voltage regulator housing 2 is provided on the motor housing 1. The mounting blocks 201 are installed on the top and bottom of the voltage regulator housing 2 by welding. The inductor chip 3 and the potentiometer 4 are installed in the voltage regulator housing 2 by bolt connection. The inductor chip 3 and the potentiometer 4 are electrically connected. The capacitor 5 and the circuit board 6 are also installed in the voltage regulator housing 2 by bolt connection. The wiring port 7 is fixedly connected to the circuit board 6 by bolt connection. It also includes a limit clamp rod 8 and a guide cylinder 9. The mounting block 201 is connected by A guide cylinder 9 is installed by welding, and a limit clamping rod 8 is rotatably arranged on the guide cylinder 9 and the mounting block 201 together. An upper and lower mounting grooves 11 are provided on the motor housing 1, and the limit clamping rod 8 can be clamped in the mounting groove 11. The mounting groove 11 of the motor housing 1 is provided with an upper and lower groove to facilitate the limit clamping rod 8 to enter the mounting groove 11. A first elastic member 10 is wound around the limit clamping rod 8, and the two ends of the first elastic member 10 are respectively connected to the guide cylinder 9 and the limit clamping rod 8. The first elastic member 10 applies pressure on the limit clamping rod 8 to move it away from the motor housing 1, so as to increase the friction between the limit clamping rod 8 and the motor housing 1, thereby making the motor housing 1 more stable during installation.

[0033] When it is necessary to install the voltage regulator housing 2 on the motor housing 1, the limit card rod 8 is slid and pressed into the installation groove 11, and then the limit card rod 8 is rotated 90 degrees so that the limit card rod 8 is stuck in the installation groove 11, so that the voltage regulator housing 2 is installed on the motor housing 1. When it is necessary to remove the voltage regulator housing 2 from the motor housing 1, the limit card rod 8 is rotated 90 degrees again, so that the limit card rod 8 can be pulled out of the installation groove 11, and then the voltage regulator housing 2 is removed. The first elastic member 10 pushes the limit card rod 8 close to the installation block 201 to increase the friction between the limit card rod 8 and the installation block 201, so as to prevent the limit card rod 8 from easily rotating in the guide cylinder 9 and disengaging from the installation groove 11; when it is necessary to regulate the voltage of the drive motor, the wiring is plugged into the wiring port 7, and the inductive chip 3 is started to work to perform the voltage regulation work.

[0034] Example 2: Based on Example 1, refer to Figure 6-Figure 8 As shown, it also includes a slide bar 13 and a block 14. The motor housing 1 is provided with two left and right slots 12 on one side close to the voltage regulator housing 2. The voltage regulator housing 2 is provided with two left and right slide grooves 1301 on one side close to the motor housing 1. The slide bar 13 is slidably arranged in the slide groove 1301. The slide bar 13 is fixedly connected to the two blocks 14 on the side close to the motor housing 1. The block 14 is made of elastic material and has a certain deformation ability. The block 14 slides and engages with the adjacent slot 12. A protrusion is provided on one side of the block 14. A step surface matching the protrusion on one side of the block 14 is provided in the slot 12. The step surface in the slot 12 is used to resist the block 14.

[0035] When installing the voltage regulator housing 2, first align the block 14 with the slot 12, then fix the voltage regulator housing 2 on the motor housing 1 by rotating the limit lever 8, and then push the block 14 backward to make the block 14 fit into the slot 12, and the protrusion on one side of the block 14 fits into the step surface matching the protrusion in the slot 12, so that the two blocks 14 fix and reinforce the voltage regulator housing 2 from both sides to prevent the voltage regulator housing 2 from falling off the motor housing 1 when the voltage regulator housing 2 vibrates with the motor housing 1.

[0036] See also Figure 8-Figure 10As shown, it also includes an inclined surface block 1401, a guide sleeve 15, a force rod 16, a push rod 17, a second elastic member 18 and a push block 19. The upper and lower ends of the slide rod 13 are fixedly connected with the inclined surface blocks 1401. Two guide sleeves 15 are fixedly connected to the top and bottom of the voltage regulator housing 2 symmetrically. The force rod 16 is slidably arranged in the guide sleeve 15. The force rod 16 squeezes the inclined surface block 1401 to slide. A push rod 17 is slidably arranged on the mounting block 201. The push rod 17 is in contact with the motor housing 1. A push block 19 is fixedly connected to one end of the push rod 17 away from the mounting block 201. The push block 19 is in contact with the force rod 16. The contact surface between the push block 19 and the force rod 16 is an inclined surface. When the push block 19 slides forward, it squeezes the force rod 16 to slide to both sides. A second elastic member 8 is connected between the push block 19 and the mounting block 201, and the second elastic member 8 is sleeved on the push rod 17.

[0037] When the voltage regulator housing 2 is fitted with the motor housing 1 for installation, the motor housing 1 squeezes the push rod 17 to slide forward, and the push rod 17 drives the push block 19 to slide forward. The push block 19 stretches the second elastic member 18 to deform, and the push block 19 squeezes the force-bearing rods 16 on both sides to slide backwards. The force-bearing rods 16 squeeze the inclined block 1401 to drive the card block to slide backward and automatically engage with the card slot 12, thereby achieving the purpose of automatically fixing the two sides of the voltage regulator housing 2 to the motor housing 1 when the voltage regulator housing 2 is fitted with the motor housing 1, and facilitating the rapid installation of the voltage regulator housing 2.

[0038] See also Fig.11 , Fig.12 and Fig.14 As shown, it also includes a guide rod 21, a third elastic member 22, a baffle 23 and a shift block 24. A transverse straight groove 20 is opened on the front side of the upper part of the voltage regulator housing 2. A baffle 23 is slidably arranged in the straight groove 20. The baffle 23 is located above the wiring port 7. A guide rod 21 is fixedly connected to the voltage regulator housing 2, and a shift block 24 is fixedly connected to the baffle 23. The shift block 24 slides on the guide rod 21. A protrusion is arranged on the shift block 24 to facilitate sliding the baffle 23 through the shift block 24. A third elastic member 22 is connected between the shift block 24 and the voltage regulator housing 2.

[0039] See also Fig.11 , Fig.12 and Fig.14 As shown, it also includes a limit rod 26. Two limit grooves 25 are opened on the mounting block 201. The limit rods 26 fixedly connected to the baffle 23 are slidably arranged in the limit grooves 25. The two limit rods 26 are located on both sides of the limit clamping rod 8.

[0040] Initially, the baffle 23 blocks the wiring port 7. When the voltage regulator housing 2 is fixed on the motor housing 1, the toggle block 24 is slid forward, and the toggle block 24 drives the baffle 23 to slide forward to open the wiring port 7. The baffle 23 squeezes the third elastic member 22 to deform, and at the same time, the baffle 23 drives the limit rod 26 to slide upward to the left and right sides of the limit card rod 8, thereby achieving the purpose of opening the wiring port 7 while limiting the limit card rod 8, preventing the limit card rod 8 from rotating and separating from the motor housing 1 during the use of the voltage regulator housing 2, and then connecting the wiring port 7 to the motor housing 1 through the signal transmission line.
