[0037] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0038] The automobile storage battery is an energy storage device for supplying power to automobile electrical equipment. During driving, the automobile will produce jolts, so that the storage battery will shake and be easily damaged by impact. In order to fix the storage battery in a specific area of the automobile, a storage battery fixing structure is usually provided in the automobile to fix and limit the storage battery.

[0039] At present, most of the automobiles on the market are provided with a storage battery tray, which fixes the storage battery on the front longitudinal beam of the vehicle body through the storage battery tray. However, the storage battery tray occupies a large space, which increases the weight and production cost of the whole vehicle.

[0040] To solve the above technical problems, the embodiments of the present application provide a storage battery fixing device. The storage battery fixing device is used for fixing and limiting the storage battery 100, and the storage battery 100 is used for devices or apparatuses requiring power supply such as automobiles. Exemplarily, the storage battery fixing device is installed in the vehicle body.

[0041] As Figure 1As shown, the battery fixing device comprises an upper pressing plate 1, two connecting pieces 2, two lower pressing plates 3 and at least two first limiting plates 4.

[0042] The upper pressing plate 1 extends along a first direction X.

[0043] The two lower pressing plates 3 are spaced apart along the first direction X, and each of the two lower pressing plates 3 is strip-shaped and extends along a second direction Y. The at least two first limiting plates 4 extend along the first direction X and are spaced apart along the second direction Y. At least one of the lower pressing plates 3 is connected with a first limiting plate 4.

[0044] The connecting pieces 2 extend along a third direction Z, and the connecting pieces 2 are used to connect the upper pressing plate 1 and the lower pressing plates 3.

[0045] The two lower pressing plates 3 are used to abut against the outer wall of the battery 100, so as to limit the battery 100 in the first direction X. The first limiting plate 4 is used to limit the battery 100 in the second direction Y. The upper pressing plate 1 is used to limit the battery 100 in the third direction Z.

[0046] Exemplarily, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0047] Specifically, as shown, Figure 2 The upper pressing plate 1 is located above the battery 100, so as to limit the battery 100 in the third direction Z and prevent the battery 100 from moving in the third direction Z.

[0048] As shown, Figure 2 The two lower pressing plates 3 are located on opposite sides of the battery 100 in the first direction X, and the two lower pressing plates 3 can abut against the outer wall of the battery 100. Exemplarily, the lower pressing plate 3 is fixed in the vehicle body by means of threaded fasteners such as bolts and screws. Under the action of the two lower pressing plates 3, the battery 100 is difficult to move in the first direction X.

[0049] As shown, Figure 3 The lower pressing plate 3 comprises a bottom plate 34, and the bottom plate 34 is provided with two mounting holes 341. Each of the two mounting holes 341 is a through hole, and the mounting hole 341 is used to position and install the battery fixing device.

[0050] Specifically, the lower pressing plate 3 is placed on the floor of the vehicle body, the mounting hole 341 is aligned with the insertion hole on the floor of the vehicle body, and then the threaded fastener is passed through the mounting hole 341, so as to fix the lower pressing plate 3 on the floor of the vehicle body. Alternatively, the lower pressing plate 3 is in interference fit with the battery 100, so as to ensure that the lower pressing plate 3 is tightly fitted with the battery 100.

[0051] The first limiting plate 4 is at least two, and the first limiting plate 4 is used to abut against the surface on both sides of the battery 100 in the second direction Y, so as to limit the displacement of the battery 100 in the second direction Y.

[0052] Exemplarily, the first limiting plate 4 is two, and the two limiting plates are connected with the same lower pressing plate 3, and the two limiting plates are arranged at two ends of the lower pressing plate 3.

[0053] Alternatively, as shown in the figure, the first limiting plate 4 is two, and the two limiting plates are arranged on the two lower pressing plates 3 respectively, and the two limiting plates are arranged at intervals in the second direction Y. Figure 1

[0054] Alternatively, the first limiting plate 4 is four, and each lower pressing plate 3 is connected with two first limiting plates 4, and the two first limiting plates 4 arranged on the same lower pressing plate 3 are arranged at intervals in the second direction Y.

[0055] As shown in the figure, the connecting piece 2 is in a rod shape and extends along the third direction Z, and the connecting piece 2 realizes the connection between the upper pressing plate 1 and the lower pressing plate 3. Figure 1

[0056] In an optional embodiment, the connecting piece 2 is in a telescopic structure, and the length of the connecting piece 2 can be adjusted. By adjusting the length of the connecting piece 2, the interval distance between the upper pressing plate 1 and the lower pressing plate 3 in the third direction Z can be changed, so that the battery fixing device is adapted to batteries 100 of different heights, and the applicability of the battery fixing device is improved. It can be understood that the connecting piece 2 can be provided with a limiting structure, and the limiting structure is used to limit the connecting piece 2 after the length of the connecting piece 2 is adjusted, so as to prevent the length of the connecting piece 2 from changing and affecting the connection stability of the upper pressing plate 1 and the lower pressing plate 3.

[0057] In another optional embodiment, the outer wall of the connecting piece 2 is provided with an external thread structure, and the connecting piece 2 is connected with the upper pressing plate 1 through a threaded fastener. By adjusting the screwing depth of the threaded fastener on the external thread structure, the position height of the threaded fastener can be adjusted, so that the connecting piece 2 is adapted to batteries 100 of different heights, and the applicability of the battery fixing device is improved. For example Figure 1 As shown in the figure, the two ends of the upper pressing plate 1 are connected with the connecting piece 2 through nuts.

[0058] ​​The battery fixing device provided by the embodiments of the present application achieves fixing and limiting of the battery 100 in the first direction X, the second direction Y and the third direction Z by arranging the upper pressing plate 1 and the lower pressing plate 3, thereby preventing the battery 100 from shaking and protecting the battery 100. Compared with the battery 100 tray covering the bottom surface of the battery 100 in the prior art, the two strip-shaped lower pressing plates 3 only abut against the outer wall of the battery 100, have a smaller size and weight, and use less material, thereby greatly reducing the space occupied by the battery fixing device and helping to reduce the weight and production cost of the whole vehicle.

[0059] In one specific embodiment, the first limiting plate 4 is two, and each lower pressing plate 3 is connected with one first limiting plate 4. The first limiting plates 4 of the two lower pressing plates 3 are oppositely arranged along the second direction Y.

[0060] In this embodiment, one of the first limiting plates 4 is arranged at the end of the first lower pressing plate 3, and the other first limiting plate 4 is arranged at the end of the second lower pressing plate 3. The two first limiting plates 4 are spaced apart along the second direction Y, thereby limiting the displacement of the battery 100 in the second direction Y.

[0061] By arranging that each lower pressing plate 3 is connected with one first limiting plate 4, the displacement of the battery 100 in the second direction Y can be limited, and the number of the first limiting plates 4 is reduced, thereby helping to reduce the weight and production cost of the battery fixing device.

[0062] Exemplarily, as shown in Figure 3 The first limiting plate 4 has a first section 41 and a second section 42 connected with each other. The first section 41 extends along the second direction Y, and the second section 42 extends along the first direction X. The first section 41 is used to be connected with the lower pressing plate 3, and the second section 42 is used to abut against the surface of the battery 100 on both sides in the second direction Y.

[0063] Optionally, the first limiting plate 4 is integrally formed with the lower pressing plate 3. Alternatively, the first limiting plate 4 is connected with the lower pressing plate 3 in a split type.

[0064] In one specific embodiment, the first limiting plate 4 is movably connected or detachably connected with the lower pressing plate 3, and the position of the first limiting plate 4 on the lower pressing plate 3 can be adjusted.

[0065] Optionally, the lower pressing plate 3 is provided with a sliding rail, and the first limiting plate 4 is slidably connected to the lower pressing plate 3 through the sliding rail, so that the first limiting plate 4 can slide relative to the lower pressing plate 3 in the second direction Y to adjust the position of the first limiting plate 4 on the lower pressing plate 3. Further, after the first limiting plate 4 is slid to a desired position, in order to fix the first limiting plate 4, a fixing member can be designed to fix the first limiting plate 4 at the current position to prevent the first limiting plate 4 from sliding, and when it is necessary to adjust the position of the first limiting plate 4 again, the fixing member can be removed.

[0066] Optionally, the lower pressing plate 3 and the first limiting plate 4 are connected through a bolt fastener, the lower pressing plate 3 is provided with a plurality of fixed points distributed along the second direction Y, and the bolt fastener passes through the insertion hole on the first section 41 of the first limiting plate 4 and the fixed points on the lower pressing plate 3 to achieve detachable connection of the lower pressing plate 3 and the first limiting plate 4. Different fixed points correspond to different positions of the first limiting plate 4 on the lower pressing plate 3, and by switching the fixed points on which the first limiting plate 4 is installed, the position of the first limiting plate 4 on the lower pressing plate 3 can be adjusted.

[0067] By setting the movable or detachable connection between the first limiting plate 4 and the lower pressing plate 3, the interval distance between adjacent first limiting plates 4 can be adjusted by adjusting the position of the first limiting plate 4 on the lower pressing plate 3, so as to adapt to different sizes of the battery 100 and improve the applicability and flexibility of the battery fixing device.

[0068] In a specific embodiment, as shown in Figure 3 The lower pressing plate 3 has a mounting plate 31 and a supporting plate 32 connected to each other, the mounting plate 31 is used to connect the lower pressing plate 3 and the connecting member 2, and the supporting plate 32 is located at one end of the mounting plate 31 in the third direction Z and is inclined to the side of the connecting member 2 relative to the mounting plate 31.

[0069] As shown in Figure 3 One end of the mounting plate 31 is connected to the bottom plate 34, and the other end is connected to the supporting plate 32. The mounting plate 31 is in the shape of a plate and is perpendicular to the first direction X. The mounting plate 31 and the bottom plate 34 can be integrally formed, or the mounting plate 31 and the bottom plate 34 can be connected in a split manner.

[0070] The mounting plate 31 is provided with a connecting hole 311 penetrating the mounting plate 31 in the thickness direction of the mounting plate 31, and the connecting member 2 can pass through the connecting hole 311 to achieve connection between the connecting member 2 and the mounting plate 31.

[0071] For example Figure 4 and Figure 5 One end of the connecting member 2 is provided with a hook connecting member 21 extending along the first direction X, and the hook connecting member 21 can be inserted into the connecting hole 311.

[0072] The hooking member 21 is further provided with a blocking member 22 at the end away from the connecting member 2. The blocking member 22 is used to limit the hooking member 21 after the hooking member 21 is inserted into the connecting hole 311, preventing the hooking member 21 from falling out of the connecting hole 311, causing the connecting member 2 and the lower pressing plate 3 to separate.

[0073] In an optional embodiment, the size of the blocking member 22 is larger than the size of the connecting hole 311. In this embodiment, the hooking member 21 is detachably connected with the blocking member 22, or the hooking member 21 is detachably connected with the connecting member 2.

[0074] In another optional embodiment, the blocking member 22 is in a strip shape and perpendicular to the first direction X. The projection of the blocking member 22 along the first direction X is partially located outside the projection of the mounting plate 31 along the first direction X, so that the blocking member 22 can be hooked and abutted with the mounting plate 31, preventing the hooking member 21 from falling out of the connecting hole 311, causing the connecting member 2 and the lower pressing plate 3 to separate.

[0075] In yet another optional embodiment, as shown in Figure 3 The connecting hole 311 is in a gourd shape, and has a small-diameter end 311a and a large-diameter end 311b that are in communication with each other. The small-diameter end 311a is located above the large-diameter end 311b. The size of the blocking member 22 is smaller than the size of the large-diameter end 311b and larger than the size of the small-diameter end 311a, so that the blocking member 22 can pass through the large-diameter end 311b. After the blocking member 22 and the hooking member 21 both pass through the large-diameter end 311b, the connecting member 2 is pulled upward, so that the hooking member 21 moves to the small-diameter end 311a. At this time, because the size of the blocking member 22 is larger than the size of the small-diameter end 311a, the blocking member 22 can prevent the hooking member 21 from falling out of the small-diameter end 311a. Further, in order to prevent the hooking member 21 from falling from the small-diameter end 311a to the large-diameter end 311b, the screw fastener at the upper end of the connecting member 2 can be adjusted to a depth of screwing, so that the upper pressing plate 1 is tightly attached to and pressed against the upper surface of the storage battery 100. At this time, as shown in Figure 5 The hooking member 21 is tightly attached to and pressed against the upper wall of the small-diameter end 311a of the connecting hole 311, so that the hooking member 21 is difficult to fall from the small-diameter end 311a to the large-diameter end 311b, ensuring the stability of the connecting member 2.

[0076] The supporting plate 32 is in a plate shape, and one end of the supporting plate 32 is connected with the mounting plate 31, and the other end is inclined to the side where the connecting member 2 is located. Through this arrangement, the supporting plate 32 can abut against the connecting member 2, supporting the connecting member 2, so as to prevent the connecting member 2 from further tilting outward, affecting the stability of the storage battery fixing device.

[0077] In a further embodiment, the support plate 32 is provided with a notch 321 at an end away from the mounting plate 31, and the notch 321 is used to accommodate the connecting piece 2.

[0078] As shown in Figure 3 , the notch 321 is located at the upper end of the support plate 32, and the notch 321 is arranged outside the connecting piece 2, and the connecting piece 2 can abut against the notch 321, and the notch 321 limits the movement of the connecting piece 2 in the second direction Y, preventing the connecting piece 2 from toppling over.

[0079] In this embodiment, by providing the notch 321 on the support plate 32, the support plate 32 can not only provide support to the connecting piece 2 in the first direction X, but also limit the movement of the connecting piece 2 in the second direction Y, making the connecting piece 2 more stable and less likely to topple over.

[0080] Further, the edge of the notch 321 is arc-shaped, increasing the contact area when the support plate 32 and the connecting piece 2 abut, which helps to improve the support effect of the support plate 32 on the connecting piece 2. For example Figure 3 , the notch 321 is semicircular.

[0081] In an embodiment, the upper pressing plate 1 comprises an upper pressing plate body 11 and two second limiting plates 12, and the two second limiting plates 12 are connected to the two ends of the upper pressing plate body 11 and are arranged at intervals along the first direction X.

[0082] As shown in Figure 1 and Figure 6 , the upper pressing plate body 11 is strip-shaped and extends along the first direction X, and the two second limiting plates 12 are sheet-shaped and arranged at the ends of the upper pressing plate body 11, and the two second limiting plates 12 are perpendicular to the first direction X.

[0083] The two second limiting plates 12 are located inside the two connecting pieces 2, and the two second limiting plates 12 can abut against the surfaces on both sides of the first direction X of the storage battery 100.

[0084] By providing the second limiting plate 12, not only can the displacement of the upper pressing plate 1 be prevented, but also the storage battery 100 can be limited in the first direction X when the storage battery 100 is impacted, preventing the displacement of the storage battery 100 and ensuring the stability of the storage battery 100.

[0085] In a further embodiment, as shown in Figure 6 , the upper pressing plate 1 further comprises a third limiting plate 13 connected to the upper pressing plate body 11, and the third limiting plate 13 extends along the second direction Y, and the third limiting plate 13 is provided with a first flange 14 at an end away from the upper pressing plate body 11, and the first flange 14 is folded towards the side of the lower pressing plate 3 relative to the third limiting plate 13.

[0086] The third limiting plate 13 extends perpendicularly to the third direction Z and along the second direction Y, as shown in Figure 6 One end of the third limiting plate 13 is connected with the upper pressing plate body 11, and the other end is provided with a first flange 14.

[0087] The first flange 14 is folded downward relative to the third limiting plate 13, and the first flange 14 is used to abut against the outer wall of the battery 100, thereby limiting the movement of the upper pressing plate 1 in the second direction Y, preventing the upper pressing plate 1 from being offset to contact the pole column on the upper surface of the battery 100, causing a short circuit phenomenon, and the first flange 14 can also limit the displacement of the battery 100 in the second direction Y, ensuring the stability of the battery 100.

[0088] Optionally, as shown in Figure 7 A reinforcing rib 15 is further arranged between the first flange 14 and the third limiting plate 13, which can improve the strength of the connection between the first flange 14 and the third limiting plate 13, preventing the angle between the first flange 14 and the third limiting plate 13 from changing.

[0089] The upper pressing plate 1 is also provided with a hollow weight-reducing hole 112 for reducing the weight of the upper pressing plate 1. As shown in Figure 6 The upper pressing plate body 11 is provided with two weight-reducing holes 112, and the third limiting plate 13 is provided with one weight-reducing hole 112.

[0090] In a further embodiment, the upper pressing plate body 11 is provided with a second flange 111 along the two side edges in the second direction Y.

[0091] As shown in Figure 6 The upper pressing plate body 11 is provided with a second flange 111 along the two side edges in the second direction Y, and the second flange 111 is folded upward relative to the upper pressing plate body 11, that is, the second flange 111 is folded upward relative to the upper pressing plate body 11.

[0092] By arranging the second flange 111, the structural strength of the upper pressing plate body 11 can be improved.

[0093] In an embodiment, as shown in Figure 3 The lower pressing plate 3 is provided with a bending portion 33 on one side in the first direction X, and the bending portion 33 is adapted to cover the boss 101 at the bottom of the battery 100.

[0094] As shown in Figure 8 The outer side wall of the battery 100 is provided with a boss 101 at the bottom, and the shape of the bending portion 33 is adapted to the shape of the boss 101, and the bending portion 33 can be closely fitted with the boss 101, thereby reducing the gap between the lower pressing plate 3 and the battery 100, and enhancing the limiting and fixing effect of the battery fixing device on the battery 100.

[0095] Further, as shown in Figure 8 The boss 101 is provided with a plurality of grooves 102, and the bent portion 33 is provided with a plurality of recesses 331, which can be inserted into the grooves 102, thereby improving the fitting degree of the bent portion 33 and the battery 100 and enhancing the limiting and fixing effect of the battery fixing device on the battery 100. Figure 3 As shown in

[0096] In one embodiment, the assembling steps of the battery fixing device include:

[0097] (1) Place one of the lower pressing plates 3 on the vehicle body floor, align the mounting hole 341 of the lower pressing plate 3 with the insertion hole on the vehicle body floor, and connect the lower pressing plate 3 and the vehicle body floor by using a threaded fastener through the mounting hole 341 and the insertion hole;
