Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a battery mounting device for an electric tricycle that is driven by a motor. It is something that

0002

[Conventional technology]

In general, electric tricycles use a space below the seat provided in the body frame to carry the battery. A battery is installed, and a motor that drives the rear wheels is installed behind the battery. Also , the steering wheel is connected to the front wheels via a shaft, and the passenger operates the steering wheel. and drive an electric tricycle. The rear part of the electric tricycle has a body flexure as shown in Figure 5. Batteries 2 and 2 are placed with an interval in the width direction of the frame 1, and between the batteries 2, Cords, harnesses, etc. are wired, and the controller 3 is installed. controller A seat pipe 4 that supports the seat is erected behind the seat pipe 3. Also, the battery A partition plate 5 is provided at the rear of the battery 2, and the battery 2 is arranged along this. It is covered with a cover 7 to prevent water from splashing. The motor that rotates the rear wheel 6 (Fig. ) is blocked by a partition plate 5 and covered by a rear cover 8.

0003 In addition, a bracket 9 is provided on the seat pipe 4 so as to protrude toward the front, and a bracket 9 is provided in the middle part of the bracket 9. The battery holders 10 are orthogonal and tightened with butterfly nuts 11, and the two batteries are The upper part of 2 is held down by both ends of battery holder 10. In addition, the front cover 7 is also It is tightened to the racket 9 with bolts. In this structure, at the tip of bracket 9 A charging connector 12 for the battery 2 is attached.

0004 On the other hand, in the case shown in FIG. 6, the battery 2 is synthesized without attaching the front cover 7. It is housed in a resin case 13, and there is a charging connector on the top side of the case 13. 12 are installed. In this case, the bracket 9 is a recess formed on the top surface of the case 13. It is designed to be hung on the portion 13a and pressed down from above. In addition, the fruit Publication No. 61-200028 discloses that a battery covered with a cover can be easily held with an arm bar. It is posted that.

[0005]

[Problem that the idea aims to solve]

By the way, battery 2 needs to be charged, so the electric tricycle needs to be powered You can charge the battery by driving close to it and connecting the power cord to the charging connector 12. being done. When charging, remove battery 2 from the electric tricycle and bring it to the supply point. It is also necessary to connect the power supply cord to charge the battery, and to replace battery 2. becomes. However, if the electric tricycle has the structure shown in Fig. 5, the front cover 7 It is necessary to remove the Then, there is a gap between the top of battery 2 and the bottom of the seat. Put your hand between them, loosen the wing nut 11, remove the battery holder 10 from the bracket 9, and remove the battery. It is necessary to take out the battery 2. Reaching into this narrow space is not easy or In addition, removing the obstructive sheet to make this work easier would require more work. It's a hassle. Even in the case of the structure shown in Fig. 5, the wing nut 11 is located below the seat. Meso work is troublesome. Even with the structure described in the official gazette, the hook is located below the seat. It is a tedious task as it is located at

[0006] This invention securely supports the battery and simplifies removal work. The present invention aims to provide a battery mounting device for an electric tricycle.

[0007]

[Means to solve the problem]

In order to achieve the above purpose, this invention has a seat pipe installed vertically on the vehicle body frame. At the top, a pin is fixed to the lower end of the vertical part, and the front end of the horizontal part arranged in the front and back direction is linked to the upper end. The rear side of the horizontal part of the bracket is fixed via the joint part, and the horizontal part of the bracket is Attach an arc-shaped battery holding bracket made of spring steel to the middle part of the Place the case that houses the battery with the contact surface of the battery holding bracket on the top surface. A hook-shaped bracket is formed in the rear floor cover to engage the pin. is provided in front of the recessed portion of the rear floor cover.

[0008]

[Effect] With the above configuration, the present invention allows the bracket to be moved upwardly and downwardly through the joint. When the case containing the battery is placed, it can be moved in the rear direction. The recess formed in the floor cover prevents skidding, and the battery holding bracket You can press the top of the case with the pad. In addition, the hook-shaped bracket is This position makes it easy to engage the pin.

【Example】

Embodiments of the present invention will be described below with reference to the accompanying drawings. Shown in Figures 1 to 3 As shown, the rear part of the electric tricycle is attached to the rear floor cover 15 on the body frame 14. An installation space is provided with a recess 15a of a predetermined size for placing the tray. The seat pipe 16 that supports the seat and the partition plate 17 are assembled behind it. There is. The rear part of the body frame 14 is covered with a rear cover 18, and a motor that drives the rear wheels 19 is installed. It is accommodated.

0010 At the front of the seat pipe 16, the upper end of the vertical part 20a and the front end of the horizontal part 20b are linked. A joined plate-shaped bracket 20 is arranged, and the rear end of the horizontal part 20b is connected to the sheet pipe 16. It is welded to the upper part via a joint 21. The horizontal part 20b of the plate bracket 20 is A bar-shaped pin 22 is attached to the bottom end of the vertical part 20a. It is being A front-opening hook-shaped block is placed above the front of the battery installation space. A pair of rackets 23 are arranged side by side, and a hook-shaped portion is arranged so as to engage with the pin 22. is formed from a groove portion 23a and a hole portion 23b.

[0011] As shown in Figure 2, the battery has a recess 24a formed in the center of the top and a charging connector 25. It is housed in a case 24 with a In addition, the horizontal part 20 of the plate bracket 20 The battery holding bracket 26 is made of spring steel and is fixed at the middle position of b. It has a flat seat 26a to make it easier to come into contact with the recess 24a of the case 24, and the middle part is curved. It has spring force. In addition, as shown in Figure 4, the battery connection is done directly using harness 27. arranged in a row, one is connected to the controller 28 and the other is wired to the charging cord 29 .

0012 Next, how to remove the battery will be explained. Lock part of plate bracket 20 (Pin 22) is located below the seat but in front of the center, so it can be easily operated. , to make it easier to remove the pin 22 from the hook-shaped bracket 23, Slightly push the front end of part 20b downward and rotate the vertical part 20a of plate bracket 20 forward. This will allow you to remove pin 22. Remove the battery by disengaging pin 22. The holding bracket 26 comes off the case 24, so remove each harness 27 and attach it to the case 24. can be extracted. To install the battery, just do the reverse operation. Place the plate bracket 20 in the upper position and insert the pin 22 into the hook bracket. When the case 24 is engaged with the bracket 23, the spring force of the battery holding bracket 26 pushes the case 24 upward. At the same time, the pin 22 is pressed against the upper part of the hole 23b by an upward force, and the case 24 is supported. It will be held. Compared to conventional work, this type of replacement work is easier to use than the elderly who are the users. This greatly reduces the burden on people with disabilities.

[0013]

[Effect of the idea]

Since the present invention is configured as described above, the seat and battery are The battery holder was tightened or loosened by inserting your hand into the gap and turning the screw. It is now possible to unfasten the battery from outside the battery, making it easier to remove the battery. It became easy. This makes battery maintenance, inspection and replacement work, and battery charging work easier. It can be done.
