Description

Technical Field

[0001] The present invention relates to a vehicle, and in particular to an electric vehicle. Background Art

[0002] See also Figure 1 At present, electric vehicles on the market adopt a swappable battery design, and most of the batteries 10 are removably inserted into the storage box, and a pressing structure 111 corresponding to the arrangement position of the battery 10 is designed on the inner side of the seat cushion 11. When the seat cushion 11 is closed, the pressing structure 111 can be used to press down the battery 10 in the storage box, thereby fixing the battery 10 and preventing the battery 10 from jumping up and down when the electric vehicle is running and causing power failure.

[0003] However, tolerances are always unavoidable in the manufacturing process for both the seat cushion 11 and the pressing structure 111. Therefore, even if the relative position, deformation, interference, and other parameter conditions between the seat cushion 11 and the pressing structure 111 have been pre-designed, it is more difficult to control the dimensional tolerance when the bottom plate area of ​​the seat cushion 11 is larger than that of the pressing structure 111. Specifically, if negative tolerances are generated between the seat cushion 11 and the pressing structure 111 during the manufacturing stage, a gap will be generated between the pressing structure 111 and the battery 10. Therefore, after closing the seat cushion 11, the pressing structure 111 may still not be able to completely fit the battery 10, resulting in a significant reduction in the fixing effect of the battery 10. In addition, in order to avoid the seat cushion 11 from being unable to be closed due to positive tolerance, the pressing structure 111 is usually made of a slightly elastic material such as rubber. However, this consideration will make the battery 10 easily jump in the direction of the pressing structure 111 due to the vibration of the vehicle body during driving, and instantly break away from the pressing effect of the pressing structure 111, thereby causing a dangerous situation of power failure during driving, and instead losing the configuration intention of the pressing structure 111, which must be improved. Summary of the invention

[0004] [Problems to be Solved by the Invention]

[0005] Therefore, an object of the present invention is to provide an electric vehicle that can ensure stable power supply from a battery used as a power source.

[0006] [Technical means to solve the problem]

[0007] Therefore, the electric vehicle of the present invention is suitable for installing at least one battery, and comprises a vehicle body, and a limiting unit installed on the vehicle body.

[0008] The vehicle body includes a storage box that defines a storage space, a seat cushion that is pivotally connected to the storage box and can openably close the storage space, and a connecting barrel that is arranged in the storage space and defines at least one insertion slot suitable for installing the at least one battery.

[0009] The limiting unit is installed on the connecting barrel and includes a fastener disposed on one side of the connecting barrel and a pressing piece disposed on the other side of the connecting barrel. The pressing piece can move between a fixed position where one end is positioned on the fastener and pressed on the at least one battery, and a release position where the pressing piece is separated from the fastener, and the pressing piece is spaced apart from the seat cushion when in the fixed position.

[0010] In some embodiments of the present invention, the connecting barrel of the vehicle body has a base defining the insertion slot, at least one first seat disposed on the base and used to install the fastener, and at least one second seat disposed on the base and used to install the pressing member, and when the at least one battery is installed in the insertion slot, the top of the base is lower than the at least one battery.

[0011] In some embodiments of the present invention, the connecting barrel of the vehicle body also has a first pivot portion that pivots the fastener on the first seat portion, and a second pivot portion that pivots the pressing member on the second seat portion, and the first pivot portion and the second pivot portion are arranged at a higher position than the base of the connecting barrel.

[0012] In some embodiments of the present invention, at least a portion of the top edge of the storage box of the vehicle body is lower than the second pivot portion.

[0013] In some embodiments of the present invention, the connecting barrel of the vehicle body further has a spring portion disposed between the pressing member and the second pivot portion, and the spring portion is used to accumulate an elastic restoring force to move the pressing member to the released position when the pressing member is located in the fixed position.

[0014] In some embodiments of the present invention, the connecting barrel of the vehicle body also has an elastic portion arranged between the fastener and the first pivot portion, and the elastic portion is used to accumulate an elastic restoring force for pivoting the fastener toward the inside to position the pressing piece when the fastener is pushed by the pressing piece to pivot outward.

[0015] In some embodiments of the present invention, the pressing member of the limiting unit has two pressing plates spaced apart from each other, and at least one reinforcing plate connected between the pressing plates.

[0016] Some embodiments of the present invention are suitable for installing two batteries, wherein the positions of the pressure plates of the pressing member correspond to the batteries respectively.

[0017] In some embodiments of the present invention, the pressing member of the limiting unit further has two buffer blocks respectively disposed on inner sides of the pressure plates.

[0018] In some embodiments of the present invention, each buffer block of the pressing member has a contact portion attached to the respective pressing plate, and two clamping portions extending from opposite sides of the contact portion and used to cooperate with each other to be positioned on the respective pressing plate.

[0019] In some embodiments of the present invention, the fastener of the limiting unit has a recessed portion facing inward, and the pressing piece has an extension portion extending outward from a side opposite to the side connected to the connecting barrel and used for mutual positioning with the recessed portion of the fastener.

[0020] In some embodiments of the present invention, the fastener and the pressing member of the limiting unit are spaced apart from each other along a front-to-back direction.

[0021] [Effects that can be achieved by the present invention]

[0022] The effect of the present invention is that the limiting unit, which is not related to the switch operation of the seat cushion, is used to specifically press against the at least one battery, and the fixing effect of the at least one battery is not related to the seat cushion, which is relatively likely to have tolerance. In addition, the limiting unit achieves the effect of fixing the at least one battery by means of the mechanism of the fastener and the pressing member interlocking with each other. Therefore, compared with simple pressing, the fixing effect of the fastener is further utilized to form a fixing effect on the position where the pressing member presses the at least one battery, ensuring that the pressing member can continue to press the at least one battery with a fixed and even force, so that the at least one battery can be stably powered.

[0023] In some embodiments of the present invention, the fastener and the pressing member are respectively installed on the first seat portion and the second seat portion of the connecting barrel, and when the at least one battery is installed in the insertion slot, the base will not completely cover the at least one battery. Therefore, when the at least one battery needs to be frequently disassembled and assembled, the contact area between the at least one battery and the base of the connecting barrel can be reduced, the mutual friction between the at least one battery and the base is reduced, and the friction force is reduced so that the at least one battery can be more easily removed from the connecting barrel.

[0024] In some embodiments of the present invention, the fastener and the pressing member are pivotally mounted on the first seat and the second seat respectively by using the first pivot portion and the second pivot portion, which not only allows the pressing member to be conveniently pivoted, but also reduces the space occupied by the lateral extension as much as possible, thereby tightening the configuration space of the components and improving the usability of the storage space. In addition, by configuring the first pivot portion and the second pivot portion at a higher position, the length of the lever arm for the pivoting of the pressing member and the fastener can be shortened when the specifications of the at least one battery are fixed, thereby reducing the chance of irreversible deformation of the pressing member and the fastener after long-term use.

[0025] In some embodiments of the present invention, the second pivot point of the pressing member when pivoting is located at a position higher than the storage box, so that the opening angle of the pressing member is not limited by the storage box, thereby optimizing the mobility of the pressing member and preventing the operation of the pressing member from interference, ensuring that there is better space margin for operating the pressing member to remove the at least one battery.

[0026] In some embodiments of the present invention, due to the elastic restoring force accumulated by the spring portion, as long as the fastening relationship between the fastener and the pressing member is released, the pressing member will automatically pop open and move to the release position where the at least one battery can be replaced, thereby further simplifying the operating steps of replacing the at least one battery and improving convenience.

[0027] In some embodiments of the present invention, the fastener can automatically pivot inward when the user presses against the pressing member due to the elastic restoring force accumulated by the elastic portion, and position the pressing member to be located in the fixed position, thereby simplifying the operation of the limiting unit.

[0028] In some embodiments of the present invention, the pressing plates of the pressing member can effectively limit the positions of the batteries according to the type of vehicle on which two batteries are to be installed. The reinforcing plate connected between the pressing plates can strengthen the overall structure of the pressing member to prevent deformation and skewness during pressing of the batteries, thereby preventing the pressing plates from affecting the limiting effect of the batteries.

[0029] In some embodiments of the present invention, the pressure plates can provide appropriate elastic buffer margins when pressing against the batteries through the buffer blocks.

[0030] In some embodiments of the present invention, each buffer block is fixed to the respective pressing plate by the clamping parts, so when any buffer block needs to be replaced, the replacement operation can be conveniently completed by applying force by hand.

[0031] In some embodiments of the present invention, since the fastener and the pressing member are spaced apart in the front-to-back direction, when the pressing member moves to the release position, it will not move to the left or right direction where the operator is usually located, thereby not affecting the operator's movements and vision when replacing the at least one battery, making the operation of replacing the at least one battery more convenient.

[0066] See also Figure 2 and Figure 3 , is an embodiment of the electric vehicle of the present invention, suitable for installing two batteries 9 ( Figure 3 Only one of them is shown due to the viewing angle.) This embodiment includes a vehicle body 2 and a limiting unit 3 installed on the vehicle body 2. It should be noted that in this embodiment, this embodiment is described as a vehicle type that is powered by two batteries 9 at the same time. However, in actual implementation, this embodiment can also be applied to other vehicle types, such as only one battery 9 is installed, and is not limited thereto.

[0067] The vehicle body 2 includes a storage box 21 defining a storage space 210, a seat cushion 22 pivotally connected to the storage box 21 to openably close the storage space 210, and a connecting barrel 23 disposed in the storage space 210 and defining two insertion slots 230 suitable for installing the batteries 9. Figure 3 and Figure 4 The connecting barrel 23 has a base 231 defining the insertion grooves 230, a first seat 232 disposed on the base 231, two second seats 233 disposed on the base 231 and located on the opposite side of the first seat 232 relative to the insertion grooves 230, a first pivot portion 234 disposed on the first seat 232, two second pivot portions 235 respectively disposed on the second seat 233, and two spring portions 236 respectively disposed on the second pivot portions 235 (see Figure 5 ), and an elastic portion 237 (see Figure 5 ). The first pivot portion 234 and the second pivot portion 235 are both disposed at a higher position than the base portion 231 of the connecting barrel 23 .

[0068] It should be particularly noted that when the batteries 9 are installed in the insertion slot 230, the top of the base 231 is lower than the batteries 9, thereby reducing the contact area between the batteries 9 and the base 231, thereby reducing the mutual friction between the batteries 9 and the base 231, and by reducing the friction force, the batteries 9 can be more easily removed from the connecting barrel 23, while also reducing the wear and tear of the batteries 9 and the connecting barrel 23 caused by long-term mutual friction.

[0069] The limiting unit 3 is installed on the connecting barrel 23, and includes a fastener 31 pivoted on the first seat 232 of the connecting barrel 23 by means of the first pivot portion 234, and a pressing member 32 pivoted on the second seat 233 of the connecting barrel 23 by means of the second pivot portions 235. Among them, a portion of the top edge of the storage box 21 of the vehicle body 2 near the front side is lower than the second pivot portion 235, so that the second pivot portion 235, which is the fulcrum of the pressing member 32 when pivoting, is located at a position higher than the storage box 21, which can prevent the opening angle of the pressing member 32 from being limited by the storage box 21, thereby optimizing the mobility of the pressing member 32 and preventing the opening angle of the pressing member 32 from being interfered. Figure 5 Specifically, since the fastener 31 is pivoted on the first seat portions 232, and the pressing member 32 is pivoted on the second seat portions 233 on the opposite side of the insertion grooves 230, the pressing member 32 can rotate toward or away from the fastener 31 with the second pivot portions 235 as the rotation axis.

[0070] See also Figure 5 and Figure 6, the fastener 31 has a recessed portion 311 facing inward. The pressing piece 32 has two pressure plates 321 that are spaced apart from each other and whose positions correspond to the batteries 9, a reinforcing plate 322 connected between the pressure plates 321, two buffer blocks 323 that are respectively disposed on the inner sides of the pressure plates 321, and an extension portion 324 that extends outward from the side opposite to the side connected to the connecting barrel 23 and is used to position relative to the recessed portion 311 of the fastener 31. Among them, the reinforcing plate 322 is mainly formed with many concave and convex structures due to the requirement that the pressure plates 321 are spaced apart from each other but must be evenly pressed on the batteries 9, thereby strengthening the overall structural strength of the pressing piece 32. In addition, Figure 7 As shown, each buffer block 323 can be made of a rubber material with sufficient elasticity, and has a contact portion 328 attached to the respective pressure plate 321, and two clamping portions 329 extending from opposite sides of the contact portion 328 and used to cooperate with each other to be positioned on the respective pressure plate 321. Each buffer block 323 can be fixed on the respective pressure plate 321 by a simple clamping positioning mechanism, not only does it not require additional tools during installation, but when any buffer block 323 needs to be replaced, it can also be directly disassembled and replaced in a simple manner.

[0071] See also Figure 5 and Figure 8 And cooperate Figure 2 and Figure 3 The pressing member 32 can be positioned in a way that the extension 324 is positioned in the recess 311 of the fastener 31 and the pressing plate 321 (see Figure 6 ) are respectively pressed on the batteries 9 and move between a fixed position, and a release position separated from the fastener 31. When the pressing member 32 is in the fixed position, it is spaced apart from the seat cushion 22. That is to say, the rotation operation of the pressing member 32 between the fixed position and the release position is completely independent of the cover setting or opening operation of the seat cushion 22. Therefore, even when the seat cushion 22 is closed, no downward pressing force is applied to the pressing member 32. Therefore, when the pressing member 32 is simply used to cooperate with the fastener 31 to limit the position of the batteries 9, it is only necessary to properly design the fastening mechanism between the pressing member 32 and the fastener 31. Without considering the seat cushion 22 which is more likely to have manufacturing tolerances, it is possible to relatively accurately design a suitable limiting force for the batteries 9, thereby achieving the purpose of ensuring that the batteries 9 are inserted into the connection terminals (not shown) without jumping or detaching and stable power supply.

[0072] The spring portion 236 is used to accumulate an elastic restoring force to move the pressing member 32 to the release position when the pressing member 32 is located at the fixed position. Therefore, when the batteries 9 need to be replaced, the pressing member 32 will move to the release position by utilizing the elastic restoring force as long as the fastening mechanism of the fastener 31 on the pressing member 32 is released. Therefore, the operator does not need to move the pressing member 32 additionally, and can complete the replacement of the batteries 9 with a simpler action. In addition, when the user operates the pressing member 32 to move to the fixed position, the pressing member 32 will first move to the release position as shown in the figure. Figure 5 The extension portion 324 pushes the fastener 31, so that the elastic portion 237 accumulates an elastic restoring force to pivot inward. When the pressing member 32 moves to the fixed position, the fastener 31 will pivot inward due to the elastic restoring force of the elastic portion 237, so that the pressing member 32 is positioned at the fixed position, thereby simplifying the operation.

[0073] It is worth mentioning that, since the fastener 31 and the pressing member 32 are arranged at intervals from each other in the front-to-back direction, when the pressing member 32 moves to the release position in a direction away from the fastener 31, it will not move to the left and right direction where the operator usually is when replacing the batteries 9, and thus will not affect the operator's action of replacing the batteries 9, nor will it block the operator's sight toward the batteries 9, making the operation of replacing the batteries 9 more convenient. In addition, the pivot fulcrum of the fastener 31 and the pressing member 32 is arranged at a position higher than the base 231, so that the length of the lever arm of the fastener 31 and the pressing member 32 can be reduced, and the chance of irreversible deformation of the fastener 31 and the pressing member 32 caused by long-term use can be reduced, thereby extending the service life of the fastener 31 and the pressing member 32 as much as possible.

[0074] In summary, the embodiment of the electric vehicle of the present invention uses the limiting unit 3 to specifically press against the batteries 9, and the fixing effect of the batteries 9 is irrelevant to the seat cushion 22 which is relatively likely to have tolerance. Moreover, the limiting unit 3 uses the mechanism of the fastener 31 and the pressing member 32 interlocking with each other. Compared with simple pressing, the fixing effect of the fastener 31 is further utilized to form a fixing effect on the position of the pressing member 32 pressing the batteries 9, ensuring that the pressing member 32 can continue to press the batteries 9 with a fixed and even force, so that the batteries 9 can be stably powered. Therefore, the purpose of the present invention can be achieved.
