Description

Technical Field

[0001] This utility model relates to starter technology, and more particularly to a starter that is easy to maintain. Background Technology

[0002] Currently, car starters are bolted directly to the engine during installation. However, this is difficult to do in the confined engine compartment, which can lead to inaccurate positioning of the starter and difficulty in fitting the bolts into the threaded holes. As a result, the starter is difficult to install and disassemble. Utility Model Content

[0003] To address the shortcomings of the existing technology, this invention proposes a starter motor that is easy to maintain.

[0004] A starter motor that is easy to maintain includes a starter motor, the starter motor having a rear cover, the rear cover having a mounting hole in the middle, and the inner wall of the mounting hole having an annular groove.

[0005] A fastener that mates with the rear cover, the fastener being mounted on the vehicle via a rotating component, and an elastic component that mates with an annular groove being provided between the rotating component and the fastener.

[0006] In this easy-to-maintain starter of the present invention, the fixing component consists of a fixing plate, a positioning ring, a column, a first blocking plate, and a spacer. The fixing plate, column, first blocking plate, and spacer are provided with threaded holes in the middle, and the diameter of the positioning ring matches the inner diameter of the mounting hole.

[0007] In this easy-to-maintain starter of the present invention, the rotating component consists of a hexagonal block, a second blocking disc, and a rod, the rod having a threaded portion that mates with a threaded hole.

[0008] In this easy-to-maintain starter of the present invention, an installation area is formed between the first and second blocking discs, and the installation area is located outside the partition block.

[0009] In this easy-to-maintain starter of the present invention, the elastic element consists of a mounting part and multiple elastic arms arranged around the mounting part, with a notch formed between the elastic arms, and a positioning hole that mates with a spacer is provided in the middle of the mounting part.

[0010] In this easy-to-maintain starter of the present invention, the elastic arm is naturally set in an arc shape, and the maximum diameter of the elastic arm in its natural state is greater than the inner diameter of the mounting hole, but smaller than the inner diameter of the annular groove.

[0011] The convenient starter motor of this utility model has the following beneficial effects: By setting fixed parts, rotating parts and elastic parts, the convenient starter motor can better position the starter motor before installation and disassembly, ensuring that the starter motor can be connected to the engine whether the bolts on the starter motor are in the installation state, thereby avoiding the instability of bolts being difficult to align with the threaded holes, facilitating the disassembly and assembly of the starter motor, and improving the efficiency of starter motor assembly and subsequent maintenance.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1 to 7 As shown, this utility model's easy-to-maintain starter includes a starter 1, a rear cover 2, a mounting hole 3 in the center of the rear cover 2, and an annular groove 4 on the inner wall of the mounting hole 3. The starter 1 also has a front cover 5, which can be bolted to the vehicle. The rear cover 2 is positioned by direct insertion. During installation and removal, the rear cover 2 is first positioned against the vehicle's fixing parts 6, facilitating the bolting of the front cover 5. This avoids difficulties in operation within the confined space of the engine compartment, preventing bolts from falling off or the starter 1 from being difficult to position, thus affecting the installation and removal of the starter 1.

[0021] The fixing component 6 is installed and positioned in conjunction with the rear cover 2. The fixing component 6 is mounted on the vehicle via a rotating component 7. An elastic component 8 that mates with the annular groove 4 is provided between the rotating component 7 and the fixing component 6. The fixing component 6 can be installed on the engine of the vehicle, facilitating the starter motor 1 to drive the flywheel to rotate.

[0022] The fixing member 6 consists of a fixing plate 9, a positioning ring 10, a column 11, a first blocking plate 12, and a spacer 13. A threaded hole 14 is provided between the fixing plate 9, column 11, first blocking plate 12, and spacer 13. The diameter of the positioning ring 10 matches the inner diameter of the mounting hole 3. A mounting area 16 is formed between the first blocking plate 12 and the second blocking plate 15, and the mounting area 16 is located outside the spacer 13. A mounting portion 17 on the elastic member 8 is disposed within the mounting area 16, and the position of the elastic member 8 is restricted by the first blocking plate 12 and the second blocking plate 15.

[0023] The rotating component 7 consists of a hexagonal block 18, a second blocking disc 15, and a rod 19. The rod 19 has a threaded portion 20 that mates with the threaded hole 14. The fixed component 6 is fixed to the engine through the threaded portion 20 on the rotating component 7.

[0024] The mounting hole 3 is also provided with a clearance hole 31 for placing the second blocking plate 15 and the hexagonal block 18.

[0025] The elastic element 8 consists of a mounting part 17 and multiple elastic arms 21 arranged around the mounting part 17. A notch 22 is formed between the elastic arms 21. The mounting part 17 is provided with a positioning hole 23 that cooperates with the spacer 13 in the middle.

[0026] The elastic arm 21 maintains an arc shape in its natural state. The maximum diameter of the elastic arm 21 in its natural state is greater than the inner diameter of the mounting hole 3, but smaller than the inner diameter of the annular groove 4.

[0027] When the rear cover 2 on the starter motor 1 is inserted into the retaining element 8 on the fixing element 6, the elastic arm 21, which was originally positioned downwards with the elastic element 8, is pushed upwards, i.e., the state after being pushed is attached. Figure 4 In the current state, because the maximum diameter of the elastic arm 21 in its natural state is larger than the inner diameter of the mounting hole 3, the mounting hole 3 will compress the elastic arm 21, causing it to deform under force. Only when it enters the annular groove 4 will it maintain its natural state, thus changing the orientation of the elastic arm 21 from downward to upward. When removing the starter motor 1, simply remove the bolts of the front cover 5 first, and then pull out the starter motor 1. This causes the annular groove 4 of the starter motor 1 to cause the elastic arm 21 to deform under force, pushing it from its original upward orientation to a downward orientation, as shown in the attached figure. Figure 4The state shown. When the elastic arm 21 is set upward or downward, it is in its natural state, so the elastic element 8 can be deformed by force to position the starter 1 on the fixed element 6, thereby facilitating the installation or removal of the starter 1 by the operator.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
