[0030] The embodiments of the present application will be described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.

[0031] As Figures 1 to 4As shown, the embodiment provides a battery mounting structure, which comprises a fixing frame 1 and an insulating elastic piece 2. The fixing frame 1 can be connected with a frame 5 of an electric vehicle, and the fixing frame 1 has a containing groove 11 for containing a battery body 6, and the containing groove 11 is limitedly matched with the battery body 6 in a first direction; the insulating elastic piece 2 is arranged above the battery body 6, and two ends of the insulating elastic piece 2 are respectively connected with two sides of the fixing frame 1, so that the insulating elastic piece 2 is limitedly matched with the battery body 6 in a second direction, and the first direction and the second direction are perpendicular.

[0032] The battery mounting structure of the utility model, insulating elastic piece 2 is arranged above battery body 6, and the two ends of insulating elastic piece 2 are respectively connected with the two sides of fixing frame 1, so that battery body 6 can be limited in containing groove 11 by insulating elastic piece 2, and battery body 6 can be limited in the first direction and the second direction by containing groove 11 and insulating elastic piece 2, thereby preventing battery body 6 from shaking in containing groove 11. Compared with the fixing mode of the prior art that uses a metal battery pressing strip to fix the battery body 6, the insulating elastic piece of the utility model can avoid the positive and negative poles of the battery from being connected to the iron, thereby easily causing the battery to catch fire, and has higher safety, and effectively solves the problem that the battery mounting structure of the prior art easily causes the battery to catch fire when driving in harsh conditions.

[0033] In some embodiments, the insulating elastic piece 2 includes but is not limited to an insulating tension belt or an insulating spring, etc., and in the utility model, the insulating elastic piece 2 is configured as an insulating tension belt. The insulating tension belt includes an outer layer 21 and a tooth-shaped inner layer 22 connected with each other, and the tooth-shaped inner layer 22 is in abutment with the battery body 6, thereby improving the friction between the insulating tension belt and the battery body 6, and ensuring that the battery body 6 does not shake when driving in harsh conditions.

[0034] Further, the material of the outer layer 21 includes but is not limited to polyurethane or neoprene. The above material has high wear resistance and toughness, good anti-aging performance, high temperature resistance, and large elasticity.

[0035] Specifically, in order to further improve the elasticity of the insulating tension belt, the outer layer 21 is provided with a plurality of reinforcing ribs 24. Figure 3 As shown, the insulating tension belt further includes a tension wire 23. The tension wire 23 is arranged between the outer layer 21 and the tooth-shaped inner layer 22. In this way, the overall structural strength of the insulating tension belt is improved, and the elasticity of the insulating tension belt is also improved.

[0036] Further, the material of the tension wire 23 includes but is not limited to glass fiber. In this way, the structural strength of the tension wire 23 can be improved. The material of the tension wire 23 can also be synthetic fiber wire or steel wire rope or aramid fiber, etc.

[0037] In the embodiment, in order to facilitate tensioning of both ends of the insulating elastic member 2, the battery mounting structure further comprises a first tensioning member 3 and a second tensioning member respectively arranged on both sides of the fixed frame 1. Among them, one end of the insulating elastic member 2 is connected with one side of the fixed frame 1 through the first tensioning member 3, and the other end of the insulating elastic member 2 is connected with the other side of the fixed frame 1 through the second tensioning member. In this way, the first tensioning member 3 and the second tensioning member can tension both ends of the insulating elastic member 2, so as to achieve the purpose of pressing the insulating elastic member 2 against the battery body 6.

[0038] Specifically, as shown in Figure 1 、 Figure 2 and Figure 4 , the first tensioning member 3 comprises a connecting seat 31, a ratchet structure 32 and a rotating rod 33. Among them, the connecting seat 31 is connected with one side of the fixed frame 1, the ratchet structure 32 is installed on the connecting seat 31 and is rotationally connected with the connecting seat 31. One end of the insulating elastic member 2 is connected with the ratchet structure 32, the rotating rod 33 is connected with the ratchet structure 32, and the rotating rod 33 is rotationally arranged. In this way, the rotating rod 33 can drive one end of the insulating elastic member 2 to move through the ratchet structure 32, so as to tension one end of the insulating elastic member 2. Among them, when the rotating rod 33 rotates towards one direction, the ratchet structure 32 can play a limiting role to prevent the rotating rod 33 from rebounding.

[0039] Further, the ratchet structure 32 comprises a rotating shaft 321, a ratchet main body 322 and a self-locking buckle 323. Among them, the rotating shaft 321 is arranged in the connecting seat 31, the ratchet main body 322 and the rotating rod 33 are both installed on the rotating shaft 321, the self-locking buckle 323 is installed on the connecting seat 31 and can be limitedly matched with the ratchet main body 322 and the rotating rod 33, and one end of the insulating elastic member 2 is sleeved on the rotating shaft 321. In this way, when the rotating rod 33 rotates towards one direction, it can drive the ratchet main body 322 to rotate. Due to the limiting action of the self-locking buckle 323, the rotating rod 33 can only rotate towards one direction at this time, so as to drive one end of the insulating elastic member 2 to stretch, thereby tightly pressing the battery body 6 in the accommodating groove 11; if it is necessary to replace the battery body 6, it is only needed to pull the self-locking buckle 323 outward, so that the self-locking buckle 323 and the rotating rod 33 are out of the limiting action, at this time the ratchet main body 322 rotates back, the tensioning state of the insulating elastic member 2 is released, and then the replacement of the battery body 6 is carried out.

[0040] In the embodiment, in order to monitor the tensioning force of the insulating elastic member 2 in real time, the battery mounting structure further comprises a tension sensor 4. Among them, the tension sensor 4 is embedded in the insulating elastic member 2, and the tension sensor 4 is used to detect the tensioning force of the insulating elastic member 2, so as to achieve the purpose of monitoring the tensioning force of the insulating elastic member 2 in real time, thereby effectively warning the loosening of the battery body 6 and avoiding unknown risks caused by the loosening of the battery body 6.

[0041] The electric vehicle of the present application has the advantages that: the insulating elastic member is arranged above the battery body 6, and the two ends of the insulating elastic member are connected with the two sides of the fixing frame 1, so that the battery body 6 is limited in the accommodating groove 11 through the insulating elastic member, and the battery body 6 is limited in the first direction and the second direction through the accommodating groove 11 and the insulating elastic member, thereby preventing the battery body 6 from shaking in the accommodating groove 11. Compared with the prior art of fixing the battery body 6 by using a metal battery pressing strip, the insulating elastic member of the present application can avoid the positive and negative poles of the battery from being connected with iron, thereby easily causing the battery to catch fire, and the safety is higher, and the problem that the battery installation structure of the prior art easily causes the battery to catch fire when running in a bad working condition is effectively solved.

[0042] The present application has the following advantages:

[0043] 1. The insulating elastic member is arranged around the top surface and the two sides of the battery pack to form a U-shaped protective structure, which has a larger constraint area than the traditional pressing strip, effectively resists external impact, reduces the risk of pole damage, and prolongs the service life of the battery. The use of insulating material blocks the conduction path and prevents short circuit caused by contact between the pressing strip and the pole, ensuring the safety of the battery in use.

[0044] 2. The first and second tensioning members are provided to realize low-torque operation, and the uniformity error of the tensioning force is less than or equal to 5%, making it easier and more convenient to replace the battery body.

[0045] 3. The insulating elastic member has high elasticity, high temperature resistance, wear resistance and aging resistance, and is not easy to deform and wear out during long-term use, ensuring stable battery fixation.

[0046] 4. The tension sensor has a response time of less than or equal to 50ms, and can sense the safety risk of the battery body in advance. Once the tension of the insulating elastic member is lower than the set threshold, an alarm will be triggered, filling the gap that the vehicle owner cannot know in advance when the battery body is loose.

[0047] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not a limitation on the embodiments of the present application. For ordinary skilled persons in the art, other different forms of changes or modifications can be made on the basis of the above description. Here, it is not necessary or possible to exhaust all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
