Description

Technical Field

[0001] The utility model relates to the technical field of automobile battery boxes, and particularly relates to an inner bracket in an automobile battery box. Background Art

[0002] The automobile battery box is an important part of an electric vehicle. It carries the power battery and plays a role in protecting the power battery. For a pure electric vehicle, the power battery provides power for the whole vehicle, and its performance has a huge impact on the performance of the whole vehicle. One of the core components of an electric vehicle is the battery box, which stores electric energy and provides power for the vehicle.

[0003] The battery pack box body is generally composed of an upper box body, a lower box body and a sealing system. At present, metal is generally used as the material of the battery pack box body. For example, the manufacturing process of steel plate material is simple, the cost is low, and it has good heat conductivity, impact resistance and thermal management ability. However, its main disadvantage is that the quality is relatively large. With the in-depth implementation of the concept of lightweight design of automobiles, aluminum alloy has gradually become the main material for realizing automobile lightweight due to its advantages such as small density, high strength and good die-casting performance.

[0004] The internal lines in the automobile battery box refer to the connecting lines inside the battery box, including high-voltage wire harnesses and low-voltage wire harnesses. The function of these lines is to connect each battery cell in the battery cell to form a complete battery cell. Since there are a large number of battery cells in the battery cell, high-voltage wire harnesses and low-voltage wire harnesses are needed to connect them. The lines connecting between the battery cells, due to their large number and different heights, are mostly directly placed inside the box body during the installation process. The vibration force generated during the vehicle driving process of the battery box is likely to cause the lines to shake and collide, affecting the stability of the line connection. Summary of the Utility Model

[0005] In view of the above problems, the present application provides an inner bracket in an automobile battery box.

[0006] To achieve the above object, the present application provides the following technical solution: An inner bracket in an automobile battery box, including a frame body distributed in an inverted U shape. An open channel is formed between the two legs of the frame body. Wire rings capable of accommodating lines are provided on the inner sides of the channels of the frame body. A pair of limiting rods distributed along the radial direction thereof are provided on the wire rings. Guide channels capable of accommodating the movement of the limiting rods are opened on the legs of the frame body. A plurality of limiting blocks distributed from top to bottom are provided outside the guide channels. The limiting rods are each provided with an intercepting structure adapted to the limiting blocks.

[0007] Further, the intercepting structures are each provided with a pressing ring sleeved on the limiting rod. In the natural state, the pressing ring is stuck into the gap between two limiting blocks distributed from top to bottom, and the pressing ring can move along the distribution direction of the limiting rod.

[0008] Furthermore, a stop ring is provided at one end of the limiting rod away from the wire loop in the intercepting structure. A pressure spring is provided in the relative space between the pressing ring and the stop ring. First and second gaskets are provided at both ends of the pressure spring respectively, and the first and second gaskets are respectively attached to the stop ring and the pressing ring. When the pressing ring moves away from the limiting block, the second gasket pushes the pressure spring to contract.

[0009] Furthermore, a first anti-slip insertion rod and a second anti-slip insertion rod are respectively provided on the first and second gaskets, and through holes for accommodating the first and second anti-slip insertion rods are respectively provided on the stop ring and the pressing ring.

[0010] Furthermore, extension blocks are provided on the pressing ring. A first control piece and a second control piece are respectively provided on the first and second gaskets, and the first and second control pieces are distributed alternately along the circumferential trajectory outside the limiting rod.

[0011] Furthermore, a detachable mounting seat is connected to the supporting feet of the frame body through positioning bolts. In the natural state, the mounting seat can close the opening below the frame body channel, and a bottom plate is provided at the bottom end of the mounting seat.

[0012] In summary, the technical effects and advantages of the present utility model are as follows:

[0013] The frame body in the present utility model can stand upright inside the battery box, and the circuit can pass through the wire loop. The circuit can be neatly arranged in the battery box to avoid the phenomenon of collision and displacement of the circuit during the long-term driving of the vehicle. According to the wiring differences between the individual battery cells inside the battery box, the limiting rod can adjust the height in the guiding channel to achieve the purpose of adjusting the height of the wire loop, and it can be applicable to circuits of different heights. After the height of the wire loop is adjusted, under the action of the intercepting structure, the stability can be maintained again, and thus the stability of the circuit can be maintained.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] refer to Figure 1 , Figure 2 The illustrated embodiment of a bracket inside a battery box of an automobile comprises a frame 1 in an inverted U-shaped distribution. The frame 1 can be erected inside the battery box. An open channel is formed between two legs of the frame 1. A wire loop 2 that can accommodate a line is provided inside the channel of the frame 1. The line can pass through the wire loop 2. The wire loop 2 is provided with a pair of limit rods 3 that can be distributed along its radial direction. The legs of the frame 1 are provided with guide channels 101 that can accommodate the movement of the limit rod 3. A plurality of limit blocks 102 distributed from top to bottom are provided outside the guide channels 101. According to the wiring differences between the various inside the battery box, the limit rod 3 can adjust the height in the guide channel 101 to achieve the purpose of adjusting the height of the wire loop 2, and can be suitable for lines of different heights. When the wire loop 2 is adjusted to different heights, the limit rod 3 is provided with an interception structure that can be matched with the limit block 102. The interception structure can maintain the stability of the limit rod 3 and the wire loop 2, and can keep the line in the battery box in an orderly and regular manner, so as to avoid the phenomenon of collision and displacement of the line during long-term driving of the vehicle.

[0023] like Figure 3 , Figure 4As shown in the figure, a pressing ring 4 sleeved on the limiting rod 3 is provided on the intercepting structure. In the natural state, the pressing ring 4 is stuck into the gap between two limiting blocks 102 distributed from top to bottom, and the limiting rod 3 and the wire ring 2 can maintain stability. If it is necessary to adjust the height of the wire ring 2, the pressing ring 4 can move along the distribution direction of the limiting rod 3 until the pressing ring 4 is far away from the limiting block 102. During the process of the pressing ring 4, the limiting rod 3 and the wire ring 2 moving synchronously, the limiting block 102 can be smoothly avoided.

[0024] The intercepting structure further includes a stop ring 6 provided at one end of the limiting rod 3 far away from the wire ring 2. A pressure spring 7 is provided in the relative space between the pressing ring 4 and the stop ring 6. First gaskets 8 and second gaskets 9 are respectively provided at both ends of the pressure spring 7. In the natural state, the elastic potential energy of the pressure spring 7 can prompt the first gaskets 8 and the second gaskets 9 to be closely attached to the stop ring 6 and the pressing ring 4 respectively, so as to keep the pressing ring 4 stable inside the gap between the two limiting blocks 102.

[0025] When the pressing ring 4 moves away from the limiting block 102, the second gasket 9 pushes the pressure spring 7 to contract. The pressing ring 4 can smoothly move along the distribution direction of the limiting rod 3 until it is far away from the limiting block 102, so that the height of the limiting rod 3 and the wire ring 2 can be smoothly adjusted. Therefore, the height of the wire ring 2 can be adjusted according to actual needs to adapt to different working requirements. After the height of the wire ring 2 is adjusted, under the action of the intercepting structure, the stability can be maintained again, and then the stability of the line can be maintained.

[0026] Embodiment 2:

[0027] As Figure 3 、 Figure 4 shown in the figure, anti-slip insertion rods 10 and anti-slip insertion rods 11 are respectively provided on the first gaskets 8 and the second gaskets 9, and through holes for accommodating the anti-slip insertion rods 10 and the anti-slip insertion rods 11 to be inserted are respectively provided on the stop ring 6 and the pressing ring 4. The connection between the anti-slip insertion rod 10 and the stop ring 6 can prevent the stop ring 6 from loosening and shifting under the vibration force of the external environment, and at the same time can maintain the tightness of the connection between the stop ring 6 and the first gasket 8. The connection between the anti-slip insertion rod 11 and the pressing ring 4, since the pressing ring 4 has been stuck into the gap between the two limiting blocks 102 and cannot be easily rotated, can further avoid the phenomenon that the first gasket 8 and the pressure spring 7 are loosened and shifted synchronously due to the loosening and shifting of the stop ring 6. It has a locking effect on the stop ring 6, maintains the stability of the position of the stop ring 6, and further maintains the stability of the intercepting structure.

[0028] As Figure 3 、 Figure 4As shown, on the premise that the pressure ring 4 is moved away from the limit block 102 so that the limit rod 3 and the wire loop 2 can smoothly adjust the height, in order to facilitate the manual control of the movement of the pressure ring 4, an extension block 5 is provided on the pressure ring 4. By operating the extension block 5, the movement of the pressure ring 4 can be quickly manually controlled to achieve the purpose of adjusting the relative distance between the pressure ring 4 and the limit rod 3.

[0029] If the stop ring 6 needs to be removed, the connection between the anti-skid plug rod 10 and the stop ring 6 needs to be released. Since the first gasket 8 and the second gasket 9 are respectively provided with a control piece 12 and a control piece 2 13, the first gasket 8 or the first gasket 8 and the second gasket 9 can be quickly manually controlled to move synchronously. Since the control piece 12 and the control piece 2 13 are staggered along the circular trajectory outside the limit rod 3, the moving paths of the control piece 12 and the control piece 2 13 are staggered, and no collision occurs, so the purpose of smoothly driving the pressure spring 7 to contract can be achieved. The anti-skid plug rod 10 can smoothly detach from the stop ring 6, and the stop ring 6 can be smoothly removed.

[0030] like Figure 1 , Figure 2 As shown, a detachable mounting base 14 is connected to the support leg of the frame 1 via a positioning bolt 16. In a natural state, the mounting base 14 can close the opening below the channel of the frame 1 to maintain the stability of the frame 1. A bottom plate 15 is provided at the bottom end of the mounting base 14, and the bottom plate 15 can be arranged inside the battery box.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
