Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to a battery fixing frame of an electric vehicle and a frame of the electric vehicle. Background Art

[0002] Electric vehicles are now a relatively common means of transportation. Electric vehicles rely on batteries or cells as a power source. With the development of the times, various types of batteries or cells have appeared on the market for use as power sources for electric vehicles.

[0003] The current technology has the following deficiencies:

[0004] 1. When selling electric vehicles, manufacturers will launch electric vehicles with different endurances based on user needs. The endurance of electric vehicles is mainly affected by the battery capacity and the number of batteries installed. Usually, manufacturers will design battery compartments of different sizes to accommodate batteries based on actual needs, which is inconvenient and users cannot make further adjustments to the endurance of the electric vehicle during subsequent use.

[0005] 2. Different types of batteries on the market often have different sizes due to different battery capacities. The fixed-size battery compartment structure on existing electric vehicles is often difficult to match the sizes of various types of batteries. Therefore, when users want to use batteries of different sizes for various reasons, they often find that the fixed structure does not match the battery size, which affects the battery fixing effect. When the electric vehicle is moving, the battery will shake and easily be damaged due to bumps.

[0006] 3. When the size of the battery does not match the battery compartment, the outer wall of the battery cannot rest against the inner wall of the battery compartment, causing the battery to shake. A common solution is to add foam boards or other items to fix the battery. If foam boards are used for fixing, the heat dissipation of the battery compartment will be affected, causing the temperature inside the battery compartment to rise and fire to occur easily.

[0049] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0050] like Figure 1-Figure 6 A battery fixing frame of an electric vehicle is shown, comprising:

[0051] The frame body 1 is used to be connected to the frame of the electric vehicle, and the interior of the frame body 1 is formed into a cavity for accommodating the battery 6. Generally, the size of the several batteries 6 arranged in the cavity can just abut against the inner side wall of the frame body 1, so that the movement of the battery in the plane direction is limited by the mutual fit between the frame body 1 and the battery 6, so as to achieve the purpose of limiting the shaking of the battery 6.

[0052] The limiting plate assembly 2 is arranged inside the frame body 1 and can divide the frame body 1 into layers so that more batteries 6 can be accommodated inside the cavity, while limiting the movement of the batteries 6 in the cavity.

[0053] The limiting plate assembly 2 includes:

[0054] The partition 3 is arranged at the bottom or top of the battery 6 , and a convex edge is formed on the peripheral side of the partition 3 , and the convex edge is used to limit the movement of the battery 6 , thereby ensuring that the battery 6 can move in the cavity inside the frame body 1 .

[0055] The insert block 4 is detachably arranged on the partition 3 , and is used to abut against two ends of the battery 6 arranged on the partition 3 , so as to limit the movement of the battery 6 .

[0056] When the battery 6 arranged in the frame body 1 cannot fill the cavity inside the frame body 1, a large space will be left between the battery 6 and the inner wall of the frame body 1. During the driving of the electric vehicle, it is very easy for the battery 6 to shake and collide with the surrounding structure, thereby causing damage to the battery 6, or an accident may occur due to the movement of the battery causing the center of gravity of the vehicle to shift.

[0057] By installing the insert block 4 on the partition 3 , the distance between the battery 6 and the inner wall of the frame body 1 is reduced, so that the insert block 4 can fit on both side surfaces of the battery 6 to limit the battery 6 .

[0058] When multiple batteries 6 are arranged side by side on the partition 3, the insert block 4 can also be placed between two adjacent batteries 6 for fixing. Alternatively, the insert block 4 can be placed at both ends of the multiple batteries 6, and the position of the batteries 6 can be fixed by relying on the mutual restriction between the batteries 6.

[0059] Furthermore, the partition 3 is formed with a convex edge 1 31 and a convex edge 2 32, which are respectively located at the upper end and the lower end of the partition 3, and the convex edge 1 31 is used to fix the bottom of the battery 6 disposed on the upper side of the partition 3. When the partition 3 is disposed above the battery 6, the convex edge 2 32 can serve the purpose of limiting the top of the battery 6.

[0060] Specific as Figure 1-Figure 3 As shown, a plurality of insertion holes 33 are formed on the partition plate 3 , and a plug pin 41 is formed on the plug block 4 , and the plug pin 41 can be inserted into the insertion hole 33 .

[0061] Since the electric vehicle batteries 6 on the market are generally produced in accordance with national standards, the size difference between the batteries 6 of different specifications produced by different manufacturers is not too large. A plurality of groups of sockets 33 with a certain spacing are provided on the partition 3, and the spacing between each group of sockets 33 matches the size of the battery 6 specified by the national standard. Therefore, when placing batteries 6 of different sizes on the partition 3, the plug blocks 4 only need to be inserted into the groups of sockets 33 corresponding to the size of the battery 6, so that the position of the battery 6 can be fixed quickly, simply and stably.

[0062] Specific as Figure 7 and Figure 8 As shown, the plug block 4 is hollow, and a reinforcing rib 48 is formed inside the plug block 4 to improve the structural strength of both sides of the plug block 4. A screw connection portion 42 is formed at the bottom end of the plug block 4, and a gasket 44 is sleeved on the outer side of the screw connection portion 42. The gasket 44 is used to increase the fastening effect, relieve stress distribution, and protect the plug block 4 and the partition 3, thereby extending the service life of the plug block 4 and the partition 3.

[0063] A mounting hole 43 is formed on one side of the screw-connecting portion 42, and a gasket 44 can pass through the mounting hole 43 and be sleeved on the outside of the screw-connecting portion 42. Compared with ordinary gaskets, the gasket 44 can be wrapped around the upper and lower ends of the screw-connecting portion 42, thereby more effectively placing the pressure generated when the bolts and nuts are tightened. At the same time, the screw holes at the upper and lower ends of the gasket 44 are pre-aligned, so in the actual assembly process, it can be more conveniently and quickly sleeved on the outside of the screw-connecting portion 42, and quickly complete positioning, so as to facilitate the tightening work.

[0064] Specific as Figure 7 and Figure 8 As shown, by forming a groove 45 on the plug block 4, the groove 45 can facilitate people to insert their fingers, so that when the plug block 4 is attached to one side of the battery 6, it is convenient to extend the finger into the groove 45 to drive the plug block 4 to move and separate the plug block 4 from the partition 3.

[0065] At the same time, since the mass of the battery 6 is generally large, if the battery 6 shakes, the hollow plug block 4 cannot provide sufficient support, resulting in damage to the side of the plug block 4. The edge of the groove 45 is located in the middle of the plug block 4, so that the structure of the groove 45 can provide additional support to the side plate of the plug block 4 to prevent the side plate of the plug block 4 from being damaged.

[0066] Furthermore, a second reinforcing rib 49 is formed in the groove 45. Since the groove 45 is formed on the plug 4, the plug 4 is easily bent by the force in the lateral direction of the viewing direction. The second reinforcing rib 49 can also effectively prevent the plug 4 from bending.

[0067] like Figure 1-Figure 7As shown, a pressing assembly 5 is hingedly connected to the upper end of the frame body 1 . The pressing assembly 5 includes at least one rotating arm 51 and a pressing portion 53 arranged on the rotating arm 51 . The pressing portion 53 is used to press against the upper end of the battery 6 .

[0068] In this embodiment, one end of the rotating arm 51 is connected to the hinge seat 12 on the frame body 1, and the rotating arm 51 can drive the pressing part 53 to rotate. When the pressing part 53 presses on the upper end of the battery 6, it can limit the battery 6 from leaving the upper end of the frame body 1. At this time, the rotating arm 51 is in a closed state.

[0069] By rotating the rotating arm 51 , the pressing portion 53 is separated from the upper end of the battery 6 , so that the battery 6 can be taken out from the frame body 1 , and the rotating arm 51 is in an open state.

[0070] In this embodiment, the top pressing assembly 5 includes at least two rotating arms 51, and the top pressing assembly 5 also includes a connecting rod 52, which is connected to the end of the rotating arm 51. The connecting rod 52 can make multiple rotating arms 51 rotate synchronously to facilitate the user to open. The pressing portion 53 is arranged on the connecting rod 52. During the closing process, multiple pressing portions 53 can press on different batteries 6 to achieve a better fixing effect.

[0071] A locking portion 54 is formed on the connecting rod 52, and a lock buckle 13 is provided on the frame body 1. The lock buckle 13 can cooperate with the locking portion 54 to fix the position of the rotating arm 51 and limit the rotation of the rotating arm 51, so that the pressing portion 53 can be tightly pressed against the upper end of the battery 6.

[0072] like Figure 1-Figure 8 As shown, a buffer seat 11 is formed on the frame body 1, and a buffer pad 55 is arranged on the rotating arm 51. The positions of the buffer seat 11 and the buffer pad 55 correspond to each other, thereby reducing the impact of the rotating arm 51 on the frame body 1 when the rotating arm 51 is rotated to a closed state, reducing the loss of the product and extending the service life.

[0073] like Figure 1-Figure 8 As shown, the partition 3 is formed with an avoidance groove 34. When the partition 3 is arranged on the top of the battery 6, the avoidance groove 34 is aligned with the terminal of the battery 6, so that when multiple layers of batteries are arranged, the normal connection of the battery 6 will not be affected.

[0074] A frame of an electric vehicle includes a frame body 7, the frame body 7 is formed with a placement groove 71 for placing a battery 6, the placement groove 71 is used to place the battery 6, and also includes a battery fixing frame of the electric vehicle as described above, the placement groove 7 and the frame body 1 cooperate to form a cavity for accommodating the battery 6.

[0075] In this embodiment, the frame body 1 is formed with connecting legs 14 , and the frame body 1 is disposed on the frame body 7 via the connecting legs 14 .

[0076] Embodiment 2:

[0077] This embodiment is basically the same as the first embodiment, except that the frame body 1 and the frame body 7 are integrally formed.

[0078] Embodiment three:

[0079] Specific as Figure 2 As shown, extension part 1 46 and extension part 2 47 are respectively protruded on both sides of one end of the plug 4. When the battery 6 is placed on the partition 3, the extension part 1 46 and the extension part 2 47 can be against one side of the battery 6, so that there is more contact area between the plug 4 and the battery 6, and the possible shaking of the battery 6 can be further reduced.

[0080] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
