Battery fixing assembly for an electric motorcycle

Abstract

The present invention relates to a battery fixing assembly for an electric motorcycle comprising a battery, a battery base, a movable cover, and a pushing mechanism. The battery is detachably attached to the battery base, and the pushing mechanism is assembled with the movable cover. When the movable cover is close to the battery, the pushing mechanism generates deformation to push the battery. Wherein, the pushing mechanism comprises a sliding member, a spring, and a buffer member. The sliding member can be moved in an accommodating portion of the movable cover. The spring is positioned between the movable cover and the sliding member for moving the sliding member. The buffer member connects the sliding member and positions outside the accommodating portion. Therefore, the buffer member can directly touch the battery to generate a first deform, and the spring can be pushed by the sliding member and the movable cover to generate a second deform. Thus, the pushing mechanism can generate two kinds of deform to absorb unnecessary force pressing the battery, so that the battery can be attached to the battery base in the best condition.

Description

[Technical Field]

[0001] The present invention relates to a battery mounting assembly for use in electric motorcycles, and more particularly to a battery mounting assembly for electric motorcycles that can avoid excessive pressure on the battery to improve the stability of the battery mounted on the battery mounting bracket, thereby preventing the battery from shaking during the operation of the electric motorcycle. [Previous Technology]

[0002] Fuel-powered motorcycles are easy to operate, convenient to park, and highly maneuverable, making them the most popular mode of transportation. However, with the rise of environmental awareness, in order to avoid the pollution of the environment by exhaust fumes emitted by fuel-powered motorcycles, there is now an electric motorcycle that can convert electrical energy into kinetic energy.

[0003] Currently, most electric motorcycles place the battery on one side of the storage box. The common method of fixing the battery in electric motorcycles is to attach a rubber body to the inside of the seat. When the seat is flipped up and covered by the storage box, the rubber body can directly press against the surface of the battery to reduce the chance of the battery shaking.

[0004] However, when the rubber body is in direct contact with the battery surface when the seat covers the storage box, it can easily increase the fastening force of the seat to the storage box, which will affect the user's convenience in operating the seat. In addition, when the rubber body is in contact with the battery for a long time, the rubber body is prone to oxidation and deformation, which will greatly reduce the area of ​​the deformed rubber body in contact with the battery. As a result, when the electric motorcycle is riding on a bumpy road, the battery is prone to shaking with the electric motorcycle, and the electric motorcycle is prone to sudden power loss and stalling during the ride.

[0005] In addition, the seats of electric motorcycles are often manufactured by injection molding. During the injection molding process, the seats are prone to warping or deformation. If the rubber body is not properly assembled into the seat, it will not be able to contact the battery in the correct position. This will indirectly affect the pressure force generated by the rubber body contacting the battery. If the pressure force is insufficient, the battery cannot be stably fixed in the storage box, which will affect the safety of the electric motorcycle while driving. Conversely, if the pressure force is too large, the rubber body will press excessively against the battery, which will increase the risk of damaging the battery. [Summary of the Invention]

[0006] The main objective of this invention is to improve the structure of the push mechanism for contacting the battery. The improved push mechanism can avoid excessive pressure on the battery to improve the stability of the battery mounted on the battery mounting base. Furthermore, during the operation of the electric motorcycle, the improved push mechanism can prevent the battery from shaking to prevent the electric motorcycle from shutting off due to power failure.

[0007] The secondary objective of this invention is to improve the structural form of the sliding member in the pushing mechanism, so that the improved sliding member can prevent the pushing spring from becoming misaligned during the pushing process, thereby ensuring that the direction of the force exerted by the pushing spring on the sliding member is stable, avoiding the force deviation caused by the misalignment of the pushing spring on the sliding member, and ensuring that the buffer member can reliably contact the battery to avoid affecting the buffering effect due to insufficient contact area between the buffer member and the battery.

[0008] To achieve the aforementioned objective, the present invention provides a battery mounting assembly for an electric motorcycle, the battery mounting assembly for the electric motorcycle comprising: a battery mounting base, a battery, a movable stop and a pushing mechanism.

[0009] The battery can be selectively assembled and disassembled into the battery mounting base, and the movable stop can be selectively located in a position close to the battery or a position far away from the battery. In the position close to the battery, the movable stop is clamped together with the battery mounting base and has a receiving portion that overlaps with the position of the battery.

[0010] The aforementioned pushing mechanism can contact the battery when the movable stop is in the aforementioned close position. The pushing mechanism includes: a slider, a pushing spring and a buffer. The slider can move inside the accommodating portion, the pushing spring is located inside the accommodating portion and is used to push the slider, and the buffer can deform and is connected to the slider. The buffer can contact the battery from outside the accommodating portion.

[0011] When the movable stop is in the aforementioned close position, the buffer will directly contact the battery so that the slider can move inside the accommodating part, causing the buffer to be squeezed by the battery and the slider to present a deformed state, and at the same time the push spring is squeezed by the movable stop and the slider to present a compressed state with shortened length.

[0012] When the movable stop is in the remote position, the buffer will return to its original shape and present an original state, and at the same time, the length of the push spring will increase and present a standby state.

[0013] In this embodiment, the two opposite ends of the accommodating portion are respectively provided as a closed end and an open end, and the interior of the accommodating portion is provided with a stop portion that can contact the sliding member. When the sliding member contacts the stop portion, the buffer member can pass through the open end and be located outside the accommodating portion. The stop portion extends along the wall of the accommodating portion, so that the stop portion has an annular shape and surrounds the open end. The maximum profile of the sliding member is larger than the open end, and the profile of the buffer member is smaller than the open end.

[0014] In a preferred embodiment, the accommodating portion is provided as an accommodating channel and an upper cover plate. The accommodating channel extends from the upper side of the movable stop to the lower side of the movable stop, such that the accommodating channel is provided with an upper inlet hole formed on the upper side of the movable stop and a lower inlet hole formed on the lower side of the movable stop. The accommodating channel forms a stop plate at the position of the lower inlet hole to form the stop portion. The upper cover plate covers the upper inlet hole to form the closed end. The lower inlet hole alone constitutes the open end.

[0015] In another preferred embodiment, the receiving portion is provided as a receiving groove and a lower cover plate. The receiving groove is recessed from the lower side of the movable stop member toward the upper side of the movable stop member, such that the receiving groove has a groove opening formed on the lower side of the movable stop member and a groove end face with a height position higher than the groove opening. The groove end face alone constitutes the closed end. The lower cover plate forms a cover plate through hole that is the open end and is connected to the groove opening, such that the lower cover plate is the stop portion.

[0016] In the two embodiments described above, the sliding member is provided with a spring receiving space for accommodating the push spring and a through hole communicating with the spring receiving space. The buffer member has an elastic body that cannot pass through the through hole and an elastic through post extending from the elastic body. The elastic through post can pass through the interior of the through hole, so that a part of the elastic through post is located inside the spring receiving space, and a part of the push spring is located outside the elastic through post.

[0017] In addition, the above-mentioned sliding member recess forms a sliding member groove, and a receiving arm is formed inside the sliding member groove. The receiving arm surrounds the spring receiving space, so that the receiving arm is located on the periphery of the pushing spring.

[0018] In addition, a portion of the above-mentioned elastic through-post is located inside the above-mentioned through-hole and is configured as a through-post body, while a portion of the above-mentioned elastic through-post is located inside the above-mentioned spring receiving space and is configured as a through-post head, and the outline of the through-post head is larger than the outline of the through-post body.

[0019] The present invention is characterized in that the pushing mechanism for contacting the battery is mainly composed of a sliding member, a pushing spring and a buffer member. The sliding member is pushed by the pushing spring and can contact the stop of the receiving part, so that the buffer member can pass through the opening end of the receiving part and be located outside the receiving part. In this way, when the movable stop is flipped up and closes to the battery, the buffer member can directly contact the battery and move the sliding member toward the closed end. Then, the battery and the sliding member will jointly squeeze the buffer member and cause the buffer member to deform. At the same time, the movable stop and the sliding member will jointly squeeze the pushing spring and cause the pushing spring to deform. Thus, the pushing mechanism can avoid excessive pressure on the battery through the pushing spring and the buffer member, thereby improving the stability of the battery installed in the battery mounting seat. In contrast, during the operation of the electric motorcycle, the pushing mechanism can prevent the battery from shaking and prevent the electric motorcycle from losing power and stalling.

[0020] In addition, the slider is recessed to form a slider groove, and the slider has a receiving arm formed in the slider groove. The receiving arm surrounds the spring receiving space to accommodate a portion of the push spring, so that the receiving arm is located on the periphery of the push spring. In this way, when the push spring pushes the slider, the receiving arm of the slider can prevent the push spring from being misaligned. Thus, the slider can ensure that the direction of the force exerted by the push spring on the slider is stable, and avoid the force exerted by the push spring on the slider due to misalignment of the push spring is deflected. The buffer can reliably contact the battery to avoid affecting the buffering effect due to insufficient contact area between the buffer and the battery.

Implementation Method

[0021] To facilitate a deeper and more detailed understanding of the structure, use, and features of the present invention, preferred embodiments are described below in conjunction with the accompanying drawings:

[0022] Please refer to Figures 1 and 2. The battery mounting assembly 1 of the electric motorcycle of the present invention mainly consists of a battery 10, a battery mounting base 20, a storage box 30, a foam body 40, a movable stop 50, and a pushing mechanism 60. The battery 10 can be selectively assembled and disassembled into the battery mounting base 20, and the battery mounting base 20 is connected to the front side of the storage box 30. The foam body 40 is connected to the upper side of the movable stop 50, and the movable stop 50 is provided with a receiving portion 51. The push mechanism 60 is installed, and the movable stop 50 is pivotally connected to the storage box 30, so that the movable stop 50 can swing back and forth relative to the battery mounting base 20 between a remote position P1 (as shown in FIG. 5A) and a near position P2. As shown, the accommodating part 51 overlaps the battery 10 in the aforementioned near position state. Furthermore, a stop part 52 is provided inside the accommodating part 51, and the opposite ends of the accommodating part 51 are respectively provided as a closed end 53 and an open end 54.

[0023] Please refer to Figures 2, 3, and 4. The receiving portion 51 of the movable stop 50 is configured as a receiving channel 511 and an upper cover plate 512. The receiving channel 511 extends from the upper side of the movable stop 50 to the lower side of the movable stop 50, such that the receiving channel 511 has an upper inlet hole 511a formed on the upper side of the movable stop 50 and a lower inlet hole 511b formed on the lower side of the movable stop 50. Furthermore, the receiving channel 511... A stop plate 511c is provided at the position of the lower inlet hole 511b to form a stop portion 52. The stop portion 52 extends along the wall of the receiving portion 51, so that the stop portion 52 is in a ring shape and surrounds the opening end 54. The upper cover plate 512 is connected to the upper side of the movable stop member 50, so that the upper cover plate 512 can cover the entire upper inlet hole 511a to form a closed end 53. Then the lower inlet hole 511b alone constitutes the opening end 54.

[0024] As shown in Figures 2, 3, and 4, the pushing mechanism 60 has three parts: a sliding member 61, a pushing spring 62, and a buffer member 63. A part of the sliding member 61 is provided with a stop block 611, while the remaining part of the sliding member 61 is provided with a receiving block 612 whose contour is larger than that of the stop block 611. The contour of the stop block 611 is larger than that of the opening end 54 of the receiving portion 51, while the contour of the receiving block 612 is smaller than that of the opening end 54. As shown, the sliding member 61 is recessed from the stop block 611 toward the receiving block 612 to form a sliding member groove. 613, and the slider 61 forms a ring-shaped receiving arm 614 inside the slider groove 613, and the receiving arm 614 surrounds to form a spring receiving space 615, and the stop block 611 passes through to form a through hole 616 communicating with the spring receiving space 615. The slider 61 is located inside the receiving channel 511 of the receiving part 51, and the slider 61 can move inside the receiving channel 511, so that the stop block 611 can selectively approach or move away from the stop plate 511c provided by the stop part 52 by moving.

[0025] The pushing spring 62 of the pushing mechanism 60 is disposed between the closed end 53 of the receiving portion 51 and the sliding member 61, such that one end of the pushing spring 62 contacts the upper cover plate 512 of the receiving portion 51, and the other end of the pushing spring 62 contacts the receiving block 612 of the sliding member 61, such that a part of the pushing spring 62 penetrates into the spring receiving space 615 of the sliding member 61, and the receiving arm 614 is located on the periphery of the pushing spring 62. When both ends of the pushing spring 62 contact the upper cover plate 512 and the receiving block 612 respectively, the pushing spring 62 will deform and enter a standby state A1. In the standby state A1, the pushing spring 62 can push the sliding member 61, so that the sliding member 61 is inside the receiving channel 511 of the receiving portion 51. The slider 61 is moved so that the stop block 611 of the slider 61 can contact the stop plate 511c of the stop portion 52. During the process of the push spring 62 pushing the slider 61, the receiving arm 614 of the slider 61 can prevent the push spring 62 from being misaligned. Thus, the slider 61 can ensure that the direction of the force exerted by the push spring 62 on the slider 61 is stable, and avoid the force exerted by the push spring 62 on the slider 61 from being deviated due to the misalignment of the push spring 62. In this embodiment, because the outline of the receiving block 612 is smaller than the outline of the opening end 54, when the stop block 611 contacts the stop portion 52, the receiving block 612 will pass through the lower inlet hole 511b of the opening end 54, so that the receiving block 612 is located outside the receiving channel 511.

[0026] The buffer 63 of the pushing mechanism 60 can deform, and the buffer 63 has a rectangular elastic body 631 and an elastic through-post 632 extending from the elastic body 631. The outline of the elastic body 631 is between the outline of the through hole 616 of the slider 61 and the outline of the lower inlet hole 511b, which is an open end 54, so that the elastic body 631 cannot be inserted into the through hole 616, while the elastic through-post 632 can be inserted into the interior of the through hole 616, with a part of the elastic through-post 632 located inside the spring receiving space 615. When the elastic through-post 632 can be inserted into the interior of the through hole 616, the buffer 63 can be connected to the receiving block 612 of the slider 61, so that the elastic body 631 and the receiving block 612 pass through. With the lower inlet hole 511b configured as the open end 54, the elastic body 631 is located outside the receiving channel 511, and the buffer 63 can present an original state B1 in which the elastic body 631 has not been deformed. In this embodiment, a part of the elastic through-hole 632 is located inside the through-hole 616 and is configured as a through-hole body 632a, and a part of the elastic through-hole 632 is located inside the spring receiving space 615 and is configured as a through-hole head 632b. The outline of the through-hole head 632b is larger than the outline of the through-hole body 632a to prevent the buffer 63 from separating from the slider 61. The through-hole head 632b is surrounded by a pushing spring 62 of the pushing mechanism 60, such that a part of the pushing spring 62 is located on the periphery of the through-hole head 632b.

[0027] Please refer to Figures 5A, 5B, 5C, and 5D for a specific application where the movable stop 50 swings to allow the pushing mechanism 60 to contact the battery 10. As shown in Figures 5A and 5B, the movable stop 50 swings to a distance position P1, causing the movable stop 50 to move away from the battery 10. When the movable stop 50 is in the distance position P1, the pushing spring 62 of the pushing mechanism 60, in the standby state A1, pushes the sliding member 61 of the pushing mechanism 60, causing the sliding member 61 to move in the receiving portion 51. The sliding member 61 moves inside the receiving channel 511 so that the stop block 611 of the sliding member 61 can contact the stop plate 511c of the stop portion 52. When the stop block 611 contacts the stop portion 52, the receiving block 612 of the sliding member 61 and the elastic body 631 of the buffer member 63 will pass through the lower inlet hole 511b of the open end 54, so that the receiving block 612 and the elastic body 631 are located outside the receiving channel 511, while the buffer member 63 is in its original state B1 when the movable stop member 50 is in the far position P1.

[0028] As shown in Figures 5C and 5D, when the movable stop 50 swings to the near position P2, the movable stop 50 will cover the storage box 30 so that the buffer 63 of the pushing mechanism 60 can directly contact the battery 10. This causes the battery 10 and the receiving block 612 of the slider 61 to jointly compress the elastic body 631 of the buffer 63, causing the buffer 63 to deform. This causes the buffer 63 to change from the original state B1 to a deformed state B2. When the buffer 63 can directly contact the battery 10, the slider 61 will move towards the upper cover plate 512, which is set as the closed end 53, so that the stop of the slider 61... Block 611 separates from the stop plate 511c provided with the stop part 52, and then the upper cover plate 512 of the movable stop 50 and the receiving block 612 of the sliding member 61 will jointly squeeze the push spring 62 and shorten the length of the push spring 62. Thus, the push spring 62 changes from the standby state A1 to a compressed state A2 with a shortened length. In this way, the push mechanism 60 can avoid excessive pressure on the battery 10 through the push spring 62 and the buffer member 63, thereby improving the stability of the battery 10 installed in the battery mounting seat 20. In contrast, during the operation of the electric motorcycle, the push mechanism 60 can prevent the battery 10 from shaking and prevent the electric motorcycle from losing power and stalling.

[0029] Please refer to Figures 6, 7, 8 and 9. In the second preferred embodiment, the difference from the first preferred embodiment is that the structure of the receiving part 51 of the movable stop 50 is the same as that of the battery 10, battery mounting base 20, storage box 30, foam body 40 and pushing mechanism 60. Therefore, in this embodiment, the structural features of the battery 10, battery mounting base 20, storage box 30, foam body 40 and pushing mechanism 60 will not be described again.

[0030] Please refer to Figures 7, 8, and 9. The receiving portion 51 of the movable stop 50 is provided as a receiving groove 513 and a lower cover plate 514. The receiving groove 513 is recessed from the lower side of the movable stop 50 toward the upper side of the movable stop 50, such that the receiving groove 513 has a groove opening 513a formed in the movable stop 50 and a groove end face 513b with a height position higher than the groove opening 513a. In this embodiment, the groove end face 513b alone constitutes a closed end 53, and the lower cover plate 514 forms a cover plate through hole 514a through it. Furthermore, the lower cover plate 514 is connected to the lower side of the movable stop 50. This causes a portion of the lower cover plate 514 to cover the groove opening 513a, while the cover plate through hole 514a connects to the receiving groove 513. Consequently, the cover plate through hole 514a forms an opening end 54, and the lower cover plate 514 forms a stop portion 52. Referring to Figures 8 and 9, in the second preferred embodiment, when the pushing mechanism 60 is disposed in the receiving portion 51 of the movable stop member 50, the stop block 611 of the sliding member 61 can contact the lower cover plate 514 which is provided as the stop portion 52, and the two ends of the pushing spring 62 of the pushing mechanism 60 respectively contact the groove end face 513b which is provided as the closed end 53 and the receiving block 612 of the sliding member 61.

Various simple modifications and alterations made by those skilled in the art based on the scope of the patent application and the description of the invention without departing from the technical scope of the present invention should still be included in the following scope of the patent application.
