Description

Technical Field

[0001] The invention relates to a battery box and an electric vehicle. Background Art

[0002] Hybrid and all-electric vehicles are becoming more and more popular. These vehicles may have many advantages over traditional internal combustion engine vehicles. For example, hybrid or electric vehicles may achieve higher fuel economy and have less or even zero emission pollution. Specifically, all-electric vehicles not only have zero emission pollution, but may also be associated with lower overall pollution.

[0003] For electric motorcycles, the swappable battery is usually placed in the vehicle compartment and is pressed against the top by the seat cushion via a rubber pad. However, during the driving of the electric motorcycle, the battery will vibrate up and down depending on the road conditions. Since the battery itself has considerable inertia, the rubber pad is often easily deformed after being impacted by the battery for a long time, which will cause the electrical connection between the battery and the electric connector of the electric motorcycle to be unstable.

[0004] Therefore, how to propose a battery box and an electric vehicle that can solve the above problems is one of the problems that the industry is eager to invest research and development resources to solve. Summary of the invention

[0011] In one or more embodiments of the present invention, the connecting rod is rotatably connected to the joint member.

[0012] In one or more embodiments of the present invention, the driving member is coupled to the connecting rod.

[0013] In one or more embodiments of the present invention, the rotating arm is configured to drive the cover to perform an opening stroke relative to the box body. The rotating arm maintains engagement with the deceleration member during the entire opening stroke.

[0014] In one or more embodiments of the present invention, the rotating arm includes two connecting rods.

[0015] In one or more embodiments of the present invention, the rotating arm is configured to drive the cover to perform an opening stroke relative to the box body. The opening stroke includes a first sub-stroke and a second sub-stroke that are consecutive. The connecting rods separate in the first sub-stroke and abut against each other in the second sub-stroke.

[0016] In one or more embodiments of the present invention, two ends of each connecting rod are respectively pivotally connected to the cover body and the joint member. The distance between the two pivot axes of the connecting rod between the cover body and the joint member is equal.

[0066] The following will disclose multiple embodiments of the present invention with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, in order to simplify the drawings, some known and commonly used structures and elements will be depicted in a simple schematic manner in the drawings.

[0067] Please refer to Figure 1 , which is a side view of an electric vehicle 100 according to an embodiment of the present invention. Figure 1 As shown, the electric vehicle 100 (e.g., a straddle-type vehicle) includes a vehicle body 110 and a battery box 200 (indicated by dotted lines). The battery box 200 is disposed on the vehicle body 110. Specifically, the vehicle body 110 has a vehicle compartment 111 (indicated by dotted lines) and a seat cushion 112. The seat cushion 112 covers the vehicle compartment 111. The battery box 200 is accommodated in the vehicle compartment 111.

[0068] It should be noted that the location of the battery box 200 on the vehicle body 110 is not limited to Figure 1 Please refer to the implementation method shown. Figure 2 , which is a side view of an electric vehicle 100 according to another embodiment of the present invention. Figure 2 As shown, the battery box 200 is mounted on the side of the vehicle body 110 .

[0069] The structures and functions of some components included in the battery box 200 as well as the connection and operation relationship between these components will be described in detail below.

[0070] Please refer to Figure 3A as well as Figure 3B . Figure 3A FIG. 1 is a perspective view of a battery box 200 according to an embodiment of the present invention. Figure 3B To illustrate Figure 3A Another perspective view of the battery box 200 in FIG. 1 , wherein some components are separated. Figure 3A and Figure 3BAs shown, the battery box 200 includes a box body 210, a cover body 220, a rotating arm 230 and a driving member 240. The box body 210 has an opening 211 and is configured to allow the battery to be accommodated in the box body 210 through the opening 211. The cover body 220 is configured to cover the opening 211. The rotating arm 230 is rotatably connected to the box body 210 and engaged with the cover body 220. The driving member 240 is disposed on the box body 210 and is configured to drive the rotating arm 230 to rotate relative to the box body 210 so that the cover body 220 leaves the opening 211. In this embodiment, the driving member 240 is an example of a torsion spring, but the present invention is not limited thereto and can be replaced by other elastic elements.

[0071] The battery box 200 further includes a buckle 260 and a latch 270. The buckle 260 is disposed on the cover 220. The latch 270 is slidably disposed on the box 210 and is configured to engage the buckle 260 when the cover 220 covers the opening 211. In some embodiments, Figure 3A As shown, the box body 210 has a slide groove 212. The latch 270 is slidably disposed in the slide groove 212. The slide groove 212 has a first inner wall 212a and a second inner wall 212b opposite to each other. When the cover body 220 covers the opening 211, the latch 270 against the first inner wall 212a can be engaged with the buckle 260 to prevent the cover body 220 from leaving the box body 210; when the latch 270 slides toward the second inner wall 212b and disengages from the buckle 260, the rotating arm 230 is driven by the driving member 240 to rotate relative to the box body 210, thereby driving the cover body 220 to leave the opening 211.

[0072] In some embodiments, Figure 3A As shown, the battery box 200 further includes a reset member 280. The reset member 280 is located in the slide groove 212 and between the latch 270 and the second inner wall 212b, so as to make the latch 270 abut against the first inner wall 212a. In actual operation, when the latch 270 and the buckle 260 are to be unlocked, the latch 270 can be moved from the first inner wall 212a to the second inner wall 212b by manual or electric means to disengage the buckle 260. After the cover 220 leaves the opening 211, the latch 270 can be released, and the reset member 280 is reset to abut against the first inner wall 212a with the released latch 270. While the user manually closes the cover 220 to the opening 211, the buckle 260 pushes the latch 270 (for example, pushes the inclined surface on the latch 270) and moves away from the first inner wall 212a. Finally, when the cover 220 completely covers the opening 211, the latch 270 is reset by the reset member 280, and is locked again with the latch 270. In some embodiments, the reset member 280 is a compression spring, but the present invention is not limited thereto and can be replaced by other elements with similar functions.

[0073] As can be seen from the aforementioned structural configuration, the battery box 200 can utilize the cover 220 to cover the opening 211 of the box body 210, so there is no need to use additional elements of the vehicle body 110 (such as the seat cushion 112) to press against the batteries accommodated in the battery box 200, thereby effectively ensuring the stability of the electrical connection between the batteries and the electrical connector on the vehicle body 110.

[0074] Please refer to Figure 4A , Figure 4B as well as Figure 4C . Figure 4A To illustrate Figure 3A 1 is a side view of the battery box 200, wherein the cover 220 is covered to the box body 210. Figure 4B To illustrate Figure 3A Another side view of the battery box 200 in FIG. 1 , wherein the cover 220 is separated from the box 210 and moved above the box 210 . Figure 4C To illustrate Figure 3A Another side view of the battery box 200 in FIG. 2, wherein the cover 220 is moved to the side of the box body 210. FIG. 4A to FIG. 4B As shown, the battery box 200 further includes a deceleration member 250 . The deceleration member 250 is disposed on the box body 210 and is configured to decelerate the rotating arm 230 during the rotation of the rotating arm 230 relative to the box body 210 .

[0075] The rotating arm 230 includes a joint member 231 and a connecting rod 232. The joint member 231 is configured to be joined with the speed reducer 250. The connecting rod 232 is connected to the joint member 231 and connected with the cover 220. In this embodiment, the joint member 231 and the connecting rod 232 are two parts of a single body structure. The connecting rod 232 is rotatably connected to the cover 220.

[0076] In this embodiment, as an example, the speed reducer 250 is a rotation damper. In more detail, the speed reducer 250 includes a gear 251, and the coupling member 231 correspondingly includes a tooth portion 231a. The tooth portion 231a is configured to mesh with the gear 251. However, the speed reducer 250 of the present invention is not limited to this, and can be replaced by other elements with a speed reduction effect. For example, the speed reducer 250 can be replaced by an element with a rough surface. This rough surface is configured to use friction to slow down the rotation speed of the rotating arm 230 when in contact with the rotating arm 230.

[0077] Under the above-mentioned structural configuration, the rotating arm 230 can drive the cover body 220 to perform an opening stroke with a first sub-stroke and a second sub-stroke relative to the box body 210. In detail, the rotating arm 230 is in a state where the cover body 220 covers the opening 211 (such as Figure 4A The tooth portion 231a of the coupling member 231 is rotated to a state where the tooth portion 231a of the coupling member 231 just contacts the gear 251 of the speed reducer 250 (as shown in FIG. Figure 4BThe stroke of the opening stroke (as shown in the state shown in the figure) can be regarded as the first sub-stroke of the aforementioned opening stroke. During this first sub-stroke, the rotating arm 230 is driven by the driving member 240 to rotate rapidly. Then, the rotating arm 230 rotates from the state where the tooth portion 231a just contacts the gear 251 of the speed reducer 250 to the state where the cover 220 stops at the side of the box body 210 (as shown in the figure). Figure 4C The stroke of the opening stroke (as shown in the state shown in the figure) can be regarded as the second sub-stroke of the aforementioned opening stroke. During this second sub-stroke, the rotating arm 230 is not only driven by the driving force of the driving member 240, but also decelerated by the deceleration member 250, so it rotates at a slower speed, thereby effectively avoiding the problems of noise and component damage caused by strong impact between components (for example, the cover body 220 impacting the box body 210).

[0078] like Figure 3B As shown, in the embodiment where the driving member 240 is a torsion spring, the rotating arm 230 may include a shaft portion 231b. The shaft portion 231b is pivotally connected to the housing 210. The torsion spring is sleeved on the shaft portion 231b. In addition, the connecting rod 232 of the rotating arm 230 has a socket 232a. One end 241 of the torsion spring is inserted into the socket 232a, thereby driving the rotating arm 230 to rotate relative to the housing 210.

[0079] Please refer to Figure 5A , Figure 5B as well as Figure 5C . Figure 5A A side view of a battery box 300 according to another embodiment of the present invention is shown, wherein the cover 220 is covered on the box 210 . Figure 5B To illustrate Figure 5A Another side view of the battery box 300 in FIG. 1 , wherein the cover 220 is separated from the box 210 and moved above the box 210 . Figure 5C To illustrate Figure 5A Another side view of the battery box 300 in which the cover 220 is moved to the side of the box 210. FIG. 4A to FIG. 4C Based on the embodiment shown, the rotating arm 230 is modified, so the components such as the box body 210, the cover body 220, the driving member 240, the speed reducer 250, the buckle 260, the latch 270 and the reset member 280 can refer to the above-mentioned related descriptions and will not be repeated here.

[0080] In this embodiment, the rotating arm 330 includes a coupling member 331 and two connecting rods 332a and 332b. The two connecting rods 332a and 332b are rotatably connected to the coupling member 331 and are respectively connected to the cover body 220. The driving member 240 is coupled to the connecting rod 332a. The tooth portion 331a of the coupling member 331 is kept in mesh with the gear 251 of the speed reducer 250 during the entire opening stroke. Under the above-mentioned structural configuration, the rotating arm 330 can drive the cover body 220 to perform an opening stroke having a first sub-stroke and a second sub-stroke relative to the box body 210.

[0081] Specifically, when the cover 220 covers the opening 211, the two connecting rods 332a and 332b are separated from each other. When the latch 270 and the buckle 260 are unlocked, the tooth portion 331a of the coupling member 331 is pulled by the gear 251 of the speed reducer 250, so that only the two connecting rods 332a and 332b are driven by the driving member 240 to move relative to the box body 210. Figure 5A The status changes to Figure 5B The two connecting rods 332a and 332b are in a state where the joint member 331 does not rotate relative to the box body 210. Figure 5B In this state, the two connecting rods 332a and 332b abut against each other and cannot continue to rotate relative to the joint member 331. In other words, the two connecting rods 332a and 332b are in a state where the cover body 220 covers the opening 211 (such as Figure 5A The state shown in FIG. 1 is rotated to a state where the two connecting rods 332a and 332b abut against each other (as shown in FIG. 1 ). Figure 5B The stroke of the opening stroke can be regarded as the first substroke of the aforementioned opening stroke. Then, the rotating arm 330 rotates from the state where the two connecting rods 332a and 332b abut against each other to the state where the cover body 220 stops at the side of the box body 210 (as shown in FIG. Figure 5C The stroke of the opening stroke (shown in the state shown) can be regarded as the second sub-stroke of the aforementioned opening stroke. During this second sub-stroke, the two connecting rods 332a, 332b and the coupling member 331 rotate together. In addition to the driving force of the driving member 240, the rotating arm 330 is also decelerated by the deceleration member 250, so it rotates at a slower speed, thereby effectively avoiding the noise and component damage caused by strong impact between components (for example, the cover body 220 hits the box body 210).

[0082] In addition, since the connecting rod 332a and the engaging member 331 do not rotate coaxially, in the embodiment where the driving member 240 is a torsion spring, the connecting rod 332a has a slot 332a1. One end 241 of the torsion spring can be slidably engaged with the slot 332a1, so as to avoid a part of the elastic force of the torsion spring being not used to drive the rotating arm 330 to rotate relative to the box body 210 and wasting it.

[0083] In some embodiments, Figure 5AAs shown, the two ends of the connecting rods 332a and 332b are respectively pivotally connected to the cover 220 and the joint member 331. The pivot distance S1 between the connecting rod 332a and the cover 220 and the joint member 331 is equal to the pivot distance S2 between the connecting rod 332b and the cover 220 and the joint member 331. In this way, during the first sub-stroke of the opening stroke of the rotating arm 330 driving the cover 220 relative to the box body 210 (see Figure 5A and Figure 5B ), the cover body 220 only translates relative to the box body 210 but does not rotate, so the space passed by the cover body 220 during the entire opening stroke can be minimized, thereby effectively avoiding interference between the cover body 220 and the vehicle body 110 or between the cover body 220 and the rider.

[0084] From the above detailed description of the specific embodiments of the present invention, it can be clearly seen that in the electric vehicle of the present invention, since the battery box includes a box body and a cover body for covering its opening, the battery contained in the battery box does not need to be pressed against by additional components of the vehicle body (such as a seat cushion), thereby effectively ensuring the stability of the electrical connection between the battery and the electrical connector on the vehicle body. In addition, by decelerating the rotating arm that drives the cover body to leave the opening of the box body through the deceleration member, the problem of strong collision between components (for example, the cover body hitting the box body) caused by the rotating arm rotating too fast can be avoided.

[0085] Although the present invention has been disclosed as above in the form of an implementation method, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the attached claims.
