Description

Technical Field

[0001] This utility model relates to the field of range-extended engine testing technology, and in particular to an external automatic docking and starting fixture. Background Technology

[0002] As an intermediate product between new energy power and traditional fuel engine power, the range-extended engine aims to solve the problem of new energy vehicles generating electricity to power the vehicle after the battery is depleted.

[0003] The range-extender engine assembly integrates a drive motor. During hot testing, the engine can be directly driven by the drive motor to achieve the test. However, before the assembly is completed, the motor and engine are tested separately. To enable the starting of products without motors, an external starting fixture is required to drive the engine to achieve hot testing. Before docking, the position of the external starting fixture needs to be adjusted according to the input structure position of the engine to facilitate docking. Since the docking structure positions of the engine in different series and models of range-extender engines are different, it is necessary to consider that the drive connection part of the external starting fixture can be adjustable to match the different docking structure positions. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] See Figures 1-5As shown in the embodiment of this utility model, an external automatic docking starting fixture is proposed for performing a starting thermal test on the engine part of a range extender engine. Specifically, it includes a base 1 and first slide rails 2 spaced apart on the base 1. Movable plates 3 are slidably mounted on the two first slide rails 2. Second slide rails 4 are spaced apart on the movable plates 3. Sliding seats 5 are slidably mounted on the two second slide rails 4. A mounting frame 6 and a guide frame 7 are mounted on the sliding seats 5. A starter motor 8 is mounted on the mounting frame 6. The shaft of the starter motor 8 is rotatably mounted on the guide frame 7. A drive gear ring 9 is mounted at the end of the shaft of the starter motor 8. After the starter motor 8 moves with the drive gear ring 9, the drive gear ring 9 connects with the docking part of the engine part, thereby being driven by the starter motor 8 to run and realize the thermal test process. Meanwhile, a first drive mechanism 10 is installed on the base 1 to drive the moving plate 3 to reciprocate, and a second drive mechanism 11 is installed on the moving plate 3 to drive the sliding seat 5 to reciprocate. The first drive mechanism 10 drives the moving plate 3 to move relative to the base 1, and the second drive mechanism 11 drives the sliding seat 5 to move relative to the moving plate 3, and the direction of movement is perpendicular in space. This allows the mounting bracket 6 and guide bracket 7 to be adjusted and moved, so that the drive motor and drive gear ring 9 can move to match the docking structure position of the engine part, ensuring a stable connection. Thus, even if the docking structure position of the engine part changes in different series of range extender engines, the matching connection can still be achieved by adjusting the position of the drive motor and drive gear ring 9.

[0028] The mounting bracket 6 is used to fix and support the drive motor, while the guide bracket 7 provides stable support for the drive motor shaft to ensure stability during rotation.

[0029] Specifically, the mounting bracket 6 includes a first bracket 61 mounted on the sliding seat 5 and a mounting shell 62 mounted on the first bracket 61. The starter motor 8 is installed inside the mounting shell 62. The guide frame 7 is provided with a support block 63 to support the mounting shell 62. The first bracket 61 serves as the main load-bearing part and, after fixing the mounting shell 62, the starter motor 8 is installed inside the mounting shell 62 for fixation. In particular, the electrical connection parts are all housed inside the mounting shell 62, thereby avoiding interference when the shaft of the starter motor 8 rotates. The support block 63 is fixed on the guide frame 7 and provides stable support for the mounting shell 62.

[0030] The mounting shell 62 is provided with a bent support leg 64, which is installed on the support block 63. After the bent support leg 64 is fastened to the support block 63, it further provides stable support for the installation state of the mounting shell 62.

[0031] Specifically, the guide frame 7 includes a first bearing plate 71 mounted on the sliding seat 5 and a second bearing plate 72 fixed on the first bearing plate 71. A reinforcing rib 73 is provided between the first bearing plate 71 and the second bearing plate 72. The rotating shaft is rotatably mounted on the second bearing plate 72. The reinforcing rib 73 forms a fixed connection between the first bearing plate 71 and the second bearing plate 72 and ensures the load-bearing strength of the second bearing plate 72. The first bearing plate 71 can be detached relative to the sliding seat 5, thereby enabling the entire guide frame 7 to be detached relative to the sliding seat 5. The support block 63 is fixed on the reinforcing rib 73, thereby fixing the support block 63 and the guide frame 7 into an integral structure. After the bent support leg 64 is fastened, the support effect on the mounting shell 62 is improved.

[0032] To facilitate the covering of the internal sliding parts and prevent large impurities from entering and causing the sliding adjustment to jam, a first baffle 12 is installed on the movable plate 3, and a second baffle 13 is installed on the base 1. A telescopic cover 14 connects the first baffle 12 and the second baffle 13. The telescopic cover 14 extends and retracts with the movement of the movable plate 3, keeping the sliding part between the first baffle 12 and the second baffle 13 covered and protected. At the same time, a protective shell 15 is installed on the movable plate 3 to cover and protect the sliding part on the movable plate 3.

[0033] Specifically, the first drive mechanism 10 includes a first lead screw mechanism 16 mounted on the base 1 and a first motor 17 connected to the first lead screw mechanism 16; the second drive mechanism 11 includes a second lead screw mechanism 18 mounted on the moving plate 3 and a second motor 19 connected to the second lead screw mechanism 18. Both the first drive mechanism 10 and the second drive mechanism 11 adopt mature reciprocating motion drive products. By controlling the forward and reverse rotation of the first motor 17 and the second motor 19, the reciprocating motion of the first lead screw mechanism 16 and the reciprocating motion of the second lead screw mechanism 18 are driven, and self-locking braking can be formed after adjustment.

[0034] Meanwhile, the base 1 includes spaced-apart I-shaped support seats 101, with support plates 102 mounted on the two support seats 101. The base 1 plays the main load-bearing role, and the I-shaped support seats 101 ensure the strength of the bottom structure. After the support plates 102 are installed, it is convenient to match the forklift forks to extend into when the entire starting tool is transported with bottom space.

[0035] In addition, a strip-shaped mounting hole is provided on the support base 101. When the starting tool is used, the relative position is fixed by fasteners passing through the strip-shaped mounting hole.
