Technical Field

[0001] The utility model relates to the technical field related to low-voltage battery installation structures, in particular to a battery fixing structure and a vehicle. Background Art

[0002] Some vehicles have their low-voltage batteries located in the front compartment. If the low-voltage battery becomes dislodged from its original location in the event of a severe head-on traffic accident or high-speed frontal collision, it could cause a low-voltage power outage, shutting off the passenger compartment screen, preventing automatic emergency calls, and preventing the doors from unlocking automatically, posing a safety hazard.

[0003] In this regard, most cars that currently have low-voltage batteries arranged in the front cabin use a pressure rod type structure to fix the low-voltage batteries to ensure that they are firmly fixed. However, on the one hand, the conventional pressure rod type fixing structure requires a large layout space, which is not conducive to the miniaturization design of the vehicle. On the other hand, it requires a large number of fixing parts and has high requirements for part precision, which has disadvantages such as complex structure, high cost, and many assembly steps. Utility Model Content

[0004] Based on this, it is necessary to provide a battery fixing structure and vehicle that takes up less space, has lower cost and is simpler to assemble, in order to address the problems of the pressure rod fixing structure used in existing low-voltage batteries, which has large space occupation, high cost and many assembly steps.

[0005] The present application first provides a battery fixing structure, comprising a base, a battery, a fixing belt, and a limiting rod, wherein both ends of the fixing belt are connected to the base to clamp and fix the battery between the base and the fixing belt;

[0006] The base is provided with a fixing belt groove, and the fixing belt includes a fixing belt body and a loop portion fixed to one end of the fixing belt body, the loop portion passes through the fixing belt groove, and the limit rod is inserted into the loop portion to limit the movement of the loop portion toward the other end of the fixing belt body, and the other end of the fixing belt body is detachably fixed to the base.

[0007] In one embodiment, the limiting rod and the collar portion are interference fit.

[0008] In one embodiment, the battery fixing structure further includes a pressing plate, and the pressing plate is fixed to the base by bolts to clamp the other end of the fixing belt body therebetween.

[0009] In one embodiment, a protrusion is provided on the side of the battery, and the pressure plate includes a first clamping portion and a second clamping portion, wherein the first clamping portion is configured to conform to the protrusion, and the second clamping portion is configured to conform to the base.

[0010] In one embodiment, the pressing plate has a plurality of ribs arranged parallel to the fixing belt.

[0011] In one embodiment, the base includes a base body and a limiting portion protruding upward from the base body, the battery is arranged on the base body and the side of the battery is in contact with the limiting portion, and the fixing belt groove is opened in the limiting portion.

[0012] In one embodiment, one side surface of the battery is in contact with the pressing plate, and the other side surfaces of the battery are in contact with the limiting portion.

[0013] In one embodiment, the battery side has a raised portion, and the limiting portion where the fixing belt slot is located is provided with a contoured protrusion protruding inwardly, and the contoured protrusion is arranged in the same shape as the raised portion to clamp and fix the fixing belt therebetween in the vertical direction.

[0014] In one embodiment, the fixing belt is a webbing.

[0015] A second aspect of the present application provides a car, comprising the above-mentioned battery fixing structure.

[0016] The battery fixing structure retains the base and is fixed by using a fixing strap. On the one hand, it can prevent the battery from flipping over or flying out of the base after being hit, ensuring the stability of the low-voltage circuit connection. On the other hand, the fixing strap occupies relatively less space than the pressure rod fixing structure and is relatively low in cost.

[0017] In addition, a loop portion is provided at one end of the fixing strap in the present application, and the limiting of one end of the fixing strap body is achieved by passing the loop portion through the fixing strap groove and then inserting the limiting rod. At this time, it is only necessary to tighten and fix the other end of the fixing strap body to complete the fixation of the battery. Since it is only necessary to fix the other end of the fixing strap body to the base, the difficulty of loading and unloading the battery fixing structure of the present application and the cost of parts are reduced.

[0028] Please combine Figure 1 、 Figure 2 as well as Figure 3 As shown, the present application first provides a battery fixing structure, including a base 10, a battery 20, a fixing belt 30 and a limiting rod 40. Both ends of the fixing belt 30 are connected to the base 10 to clamp and fix the battery 20 between the base 10 and the fixing belt 30; the base 10 is provided with a fixing belt groove, and the fixing belt 30 includes a fixing belt body 31 and a ring portion 32 fixed to one end of the fixing belt body 31, the ring portion 32 passes through the fixing belt groove, and the limiting rod 40 is inserted into the ring portion 32 to limit the movement of the ring portion 32 toward the other end of the fixing belt body 31, and the other end of the fixing belt body 31 is detachably fixed to the base 10.

[0029] In the present application, on the basis of retaining the base 10, the fixing belt 30 is used for fixing. On the one hand, the fixing belt 30 can firmly fix the battery 20 on the base 10 to prevent the battery 20 from flipping over or flying out of the base 10 after being hit, thereby ensuring the stability of the low-voltage circuit connection. On the other hand, the fixing belt 30 occupies a relatively small space relative to the pressure rod fixing structure and has a relatively low cost.

[0030] In addition, a loop portion 32 is provided at one end of the fixing strap 30 in the present application, and the loop portion 32 is passed through the fixing strap groove and then inserted into the limiting rod 40 to achieve the limitation of one end of the fixing strap body 31. At this time, it is only necessary to tighten and fix the other end of the fixing strap body 31 to complete the fixation of the battery 20. Since it is only necessary to fix the other end of the fixing strap body 31 to the base 10, the loading and unloading difficulty and parts cost of the battery fixing structure of the present application are reduced, and both ends of the fixing strap 30 can be removed from the base 10 as needed, which is also convenient for subsequent disassembly work.

[0031] It should be noted that the projection of the limiting rod 40 along the axis of the fixing belt groove covers the fixing belt groove to ensure that the limiting rod 40 can abut against the outer surface of the base 10 .

[0032] In some embodiments, the limiting rod 40 and the collar portion 32 are interference-fitted to prevent the limiting rod 40 from being separated from the collar portion 32 along its own axial direction, thereby preventing the limiting rod 40 from failing to be released.

[0033] In some embodiments, the limiting rod 40 may be made of plastic or metal, as long as its structural strength can meet the use requirements.

[0034] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the battery fixing structure further includes a pressing plate 50 , and the pressing plate 50 is fixed to the base 10 by bolts to clamp and fix the other end of the fixing belt body 31 therebetween.

[0035] Of course, in some other embodiments, the other end of the fixing belt body 31 can also be fixed to the base 10 by other commonly used fixing methods, as long as the other end of the fixing belt body 31 is detachably fixed to the base 10. This application does not give examples one by one here.

[0036] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, a protrusion 21 is provided on the side of the battery 20, and the pressure plate 50 includes a first clamping portion 51 and a second clamping portion 52, wherein the first clamping portion 51 is configured to imitate the protrusion 21, and the second clamping portion 52 is configured to imitate the base 10.

[0037] First, the two sets of clamping fixation, namely, the protrusion 21 and the first clamping portion 51, and the base 10 and the second clamping portion 52, can effectively improve the fixing reliability of the fixing belt 30. Secondly, since the first clamping portion 51 and the protrusion 21 are configured in a contoured manner, the fixing belt 30 will be deformed into a step shape that fits the protrusion 21 under the extrusion of the first clamping portion 51, thereby further increasing the fixing reliability of the fixing belt 30.

[0038] Please combine Figure 1as well as Figure 3 As shown, in some embodiments, the pressing plate 50 has a plurality of ribs 53 arranged parallel to the fixing belt 30 to improve the structural strength of the pressing plate 50.

[0039] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the base 10 includes a base body 11 and a limiting portion 12 protruding upward from the base body 11, the battery 20 is arranged on the base body 11 and the side of the battery 20 is in contact with the limiting portion 12, and the fixing belt groove is opened in the limiting portion 12; the limiting portion 12 can limit the movement of the battery 20 in the horizontal direction.

[0040] Preferably, one of the side surfaces of the battery 20 is in contact with the pressure plate 50, and the other side surfaces of the battery 20 are in contact with the limiting portion 12, so as to achieve preliminary limiting of the battery 20 through the pressure plate 50 and the circumferential limiting portion 12, limit its displacement in the horizontal direction, and achieve a better fixing effect in conjunction with the fixing belt 30.

[0041] In some embodiments, the base body 11 is in the shape of a quadrilateral, and a pressure plate 50 is provided on one side of one set of opposite sides of the quadrilateral, and a fixing belt groove is provided on the limiting portion 12 on the other side, and a limiting portion 12 is provided on the other set of opposite sides of the quadrilateral, and the length of the limiting portion 12 accounts for half of the length of the side of the quadrilateral; such an arrangement ensures that the battery 20 can be limited while minimizing the amount of material used and reducing the cost of parts.

[0042] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the battery 20 has a protrusion 21 on the side, and the limiting portion 12 where the fixing belt groove is located is provided with a contoured protrusion 121 protruding inward. The contoured protrusion 121 is arranged in the same shape as the protrusion 21 to clamp and fix the fixing belt 30 between the two in the vertical direction.

[0043] The fixing belt 30 is clamped and fixed by the contoured protrusion 121 and the raised portion 21 . Under the pressure of the contoured protrusion 121 and the raised portion 21 , the fixing belt 30 is deformed into a step shape that fits the raised portion 21 , thereby further increasing the fixing reliability of the fixing belt 30 .

[0044] In some embodiments, the fixing strap 30 is a webbing, which has high strength and relatively low cost.

[0045] A second aspect of the present application provides a car, comprising the above-mentioned battery fixing structure.
