Based on embodiment 3, as shown in fig. 13, 14 and 15, the wading closing assembly 10 is further included, the wading closing assembly 10 for preventing water from entering the battery housing frame 2 is disposed on the battery housing frame 2, the wading closing assembly 10 includes a fixed cylinder 101, a triangular groove plate 102, a sliding closing plate 103, a slotted disc 104, a pulling groove plate 105 and a fixed spring 106, the fixed cylinder 101 is symmetrically and fixedly connected to the outer wall of the battery housing frame 2, heat generated by the operation of the battery inside the battery housing frame 2 is dissipated through the fixed cylinder 101, the five triangular groove plates 102 are fixedly connected to the outer portion of the fixed cylinder 101 in a circumferentially distributed manner, the sliding closing plate 103 for closing the fixed cylinder 101 is slidably connected to the triangular groove plate 102, the pulling groove plate 105 is slidably connected to the top of the battery housing frame 2 in a symmetrical and sliding manner, the slotted disc 104 is slidably connected to the pulling groove plate 105, five arc-shaped sliding grooves are formed in the slotted disc 104 in an annular distributed manner, the slotted disc 104 on the same side is in limit fit with the sliding sealing plate 103, a fixed spring piece 106 is fixedly connected to the pulling slotted plate 105, and the fixed spring piece 106 is tightly attached to the battery placing frame body 2.

Through fixed drum 101, be favorable to the battery to place the inside ventilation cooling of framework 2, prevent that the battery temperature of framework 2 inside is placed to the battery is too high, prolong its life, when the place ahead that electric bicycle went has water hole, the user uses the foot to promote pulling frid 105 and moves left, it can drive slotted disc 104 and rotate, slotted disc 104 then can extrude through the inside removal of slip shrouding 103, make slip shrouding 103 seal fixed drum 101, prevent that outside water from getting into inside the framework 2 is placed to the battery, play the guard action, when the road is dry, the user uses the foot to promote pulling frid 105 and resets, slotted disc 104 and the last device of it can reverse the resetting thereupon, thus, can prevent that water from getting into inside the framework 2 is placed to the battery.

Example 5

On the basis of embodiment 4, as shown in fig. 14, the battery storage rack further includes a linkage assembly 11, the linkage assembly 11 is disposed on the battery storage rack 2, the linkage assembly 11 includes a fixed slot seat 111 and a sliding special-shaped slot rod 112, the fixed slot seat 111 is symmetrically and fixedly connected to the right side of the outer wall of the battery storage rack 2, the sliding special-shaped slot rod 112 is jointly slidably connected between the two fixed slot seats 111, straight sliding slots are formed in both ends of the sliding special-shaped slot rod 112, and the sliding special-shaped slot rod 112 is slidably matched with the slotted disc 104.

When one slotted disc 104 and the device thereon rotate, the other slotted disc 104 and the device thereon also rotate due to the action of the sliding special-shaped slotted rod 112, so that the two fixed cylinders 101 are both sealed by the sliding sealing plate 103, and the use is convenient.

Example 6

On the basis of embodiment 5, as shown in fig. 16, the pedal type bicycle further comprises an alarm 12, the alarm 12 is fixedly installed on the left side of the outer wall of the battery placing frame body 2, the alarm 12 is located inside the pedal seat 1, and the alarm 12 plays a role in warning for a user.

When the battery inside the battery placing frame body 2 is manually disassembled, the equipment can vibrate, the alarm 12 gives an alarm, when the battery is disassembled by illegal personnel, a user can be reminded, and meanwhile, the illegal personnel can be prevented from damaging the alarm 12 because the alarm 12 is installed inside the equipment.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
