[0027] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to solve the problem that the fixing structure of the battery pack in the prior art is prone to loosening and thus has low safety, the present application provides a fastening component and a battery pack structure having the same.

[0029] Please refer to FIGS. 1 to 5, the present application provides a fastening component, which comprises a mounting piece 10 and a first limiting piece 30; the mounting piece 10 is used to be connected with a to-be-fixed component and a mounting frame 20 respectively, so as to fix the to-be-fixed component on the mounting frame 20; the first limiting piece 30 is connected with the mounting piece 10, and the first limiting piece 30 encloses a first limiting portion, which is connected with the mounting frame 20 in a matched manner, so as to limit the movement of the mounting piece 10 along a first direction.

[0030] In one aspect of the technical solution of the present embodiment, after the mounting piece 10 is connected with the mounting frame 20 and the to-be-fixed component respectively to fix the to-be-fixed component, the movement of the mounting piece 10 along the first direction is limited by the first limiting piece 30, so that the shaking and displacement of the to-be-fixed component and the loosening of the mounting piece 10 can be significantly reduced during the carrying process, so as to ensure the safe fixing of the to-be-fixed component, and thus the problem that the fixing structure of the battery pack 50 in the prior art is prone to loosening and thus has low safety is solved.

[0031] In the present embodiment, the to-be-fixed component is a battery pack 50.

[0032] In the present application, the fastening component further comprises a second limiting piece 40, which is connected with the mounting piece 10; the second limiting piece 40 encloses a second limiting portion, which is connected with the mounting frame 20 in a matched manner, so as to limit the movement of the mounting piece 10 along a second direction; the second direction is arranged perpendicularly to the first direction.

[0033] By the above arrangement, compared with the conventional fastener, the fastening component in the application simultaneously utilizes the first limiting piece 30 and the second limiting piece 40 to be connected with the mounting frame 20 respectively, so as to limit the movement of the mounting piece 10 in two directions, that is, even in the long-term vibration or temperature change environment, the fastening state can be maintained, the loosening and falling off of the mounting piece 10 are prevented, the safe fixation of the to-be-fixed component is ensured, and then the problem of low safety caused by the easy loosening of the fixing structure of the battery pack 50 in the prior art is solved. Moreover, through the cooperation of the first limiting piece 30, the second limiting piece 40 and the mounting frame 20, even in the case of loosening of the mounting piece 10, the fixation of the to-be-fixed component can be maintained, the contact with the live component is avoided, and the occurrence of safety problems such as short circuit is prevented. Moreover, the assembly and disassembly process of the fastening component is more convenient, without the need for complex tools and operations, while ensuring the integrity of the disassembled component, facilitating subsequent maintenance and reuse.

[0034] As shown in Figures 1 to 3 The mounting piece 10 includes a first mounting plate 11, a second mounting plate 12 and a third mounting plate 13, and the first mounting plate 11, the second mounting plate 12 and the third mounting plate 13 are arranged in a perpendicular connection manner two by two. The two adjacent mounting plates in the mounting piece 10 are connected with the mounting frame 20 and the to-be-fixed component respectively, and the first limiting piece 30 and the second limiting piece 40 are connected with the other mounting plate in the mounting piece 10 respectively. In this way, the three mounting plates of the mounting piece 10 are connected with each other in a perpendicular manner, forming a more stable structure, improving the mechanical strength and rigidity of the entire fastening component, and reducing the risk of deformation when bearing external force. Moreover, the first limiting piece 30 and the second limiting piece 40 are connected with the first mounting plate 11 respectively, so that they can limit the mounting piece 10 in different directions respectively, thereby limiting the movement of the mounting piece 10 in the first direction and the second direction respectively, and providing comprehensive stability control to prevent the problem of loosening or falling off of the mounting piece 10 during the carrying process after the mounting piece 10 is fixedly connected with the battery pack 50.

[0035] Specifically, the first mounting plate 11 has a first side portion 110, the first limiting piece 30 includes a first bending plate 31 and a first limiting plate 32; the first bending plate 31 is connected with the first side portion 110; the first limiting plate 32 is connected with the first bending plate 31, and the first limiting plate 32 and the first bending plate 31 and the outer wall surface of the first mounting plate 11 enclose a first limiting groove 33, and the first limiting groove 33 is connected with the bottom plate 21 of the mounting frame 20 to limit the movement of the mounting piece 10 along the first direction.

[0036] In this way, by limiting the movement of the mounting member 10 in the first direction, it can be ensured that the mounting member 10 will not displace in this direction, and the battery pack 50 can be kept stable even if it encounters shocks or impacts during transportation, thereby reducing the risk of loosening of the mounting member 10. Moreover, the first limiting groove 33 formed by the first bending plate 31, the outer wall surface of the first mounting plate 11 and the first limiting plate 32 is a "closed" limiting structure, which provides stronger support and limiting capacity in the first direction. Compared with the connection mode of the mounting member 10 alone, it can withstand greater external force without deformation or damage, so that the mounting member 10 can be stably fixed on the basis of fixing the battery pack 50. Moreover, the assembly and disassembly process of the fastening component is more convenient, and complex tools are not required.

[0037] In this embodiment, the first bending plate 31 is made of plastic material, and the first limiting plate 32 is provided with a first stop portion 34 at the end away from the first bending plate 31. The bottom surface of the bottom plate 21 of the mounting plate is provided with a first mounting protrusion 22, so that after the first limiting groove 33 is clamped with the bottom plate 21 of the mounting frame 20, the first limiting plate 32 drives the first stop portion 34 to move to abut against the side of the first mounting protrusion 22 away from the first bending plate 31.

[0038] In this way, since the first bending plate 31 is made of plastic material, it can be slightly deformed by controlling the first limiting plate 32 to drive the first bending plate 31 to adapt to the shape of the bottom plate 21 of the mounting frame 20 during installation, so as to ensure the close clamping of the first limiting groove 33 and the bottom plate 21 of the mounting frame 20. After the first limiting groove 33 is clamped with the bottom plate 21 of the mounting frame 20, the first stop portion 34 will move to abut against the first mounting protrusion 22, so that even if shocks or impacts occur during transportation or operation, the cooperation of the first stop portion 34 and the first mounting protrusion 22 can prevent the movement of the mounting member 10 in the first direction, thereby preventing further loosening and self-locking. Moreover, the first bending plate 31 made of plastic material is easy to adjust during assembly, so as to ensure the accurate alignment of the first limiting groove 33 and the bottom plate 21 of the mounting frame 20, thereby improving the accuracy and efficiency of the overall assembly. Moreover, the cooperation of the first stop portion 34 and the first mounting protrusion 22 not only provides a limiting effect at the initial stage of installation, but also maintains the stable connection between the first mounting plate 11 and the mounting frame 20 during long-term use, so that good fixing effect can be maintained even in harsh environments (such as temperature change, vibration, etc.), thereby preventing loosening of the mounting member 10 and displacement of the battery pack 50.

[0039] Alternatively, the first bending plate 31 and the first limiting plate 32 are both made of steel material, and the first limiting groove 33 formed by the first bending plate 31, the first limiting plate 32 and the bottom surface of the first mounting plate 11 is clamped with the bottom plate 21 of the mounting frame 20, so as to limit the movement of the mounting member 10 in the first direction.

[0040] Optionally, the first bent plate 31 can be an arc-shaped plate or a right-angle plate, which can be adapted according to the end surface of the mounting frame 20 along the length direction thereof.

[0041] Specifically, the first mounting plate 11 further has a second side portion 111 connected with the first side portion 110, and the second limiting piece 40 includes a second bent plate 41 and a second limiting plate 42; the second bent plate 41 is connected with the second side portion 111; the second limiting plate 42 is connected with the second bent plate 41, and the second limiting plate 42, the second bent plate 41 and the outer wall surface of the first mounting plate 11 enclose a second limiting groove 43, which is connected with the bottom plate 21 of the mounting frame 20 to limit the movement of the mounting piece 10 in the second direction.

[0042] In this way, the second limiting groove 43 enclosed by the second bent plate 41, the second limiting plate 42 and the bottom surface of the first mounting plate 11 is connected with the bottom plate 21 of the mounting frame 20, which can effectively limit the movement of the mounting piece 10 in the second direction. This means that in the fixed structure of the battery pack 50, not only is it limited in the first direction (i.e. the length direction of the mounting frame 20), but also in the second direction (i.e. the width direction of the mounting frame 20), providing overall stability and anti-loose protection. This multi-directional limiting design is particularly important for preventing the battery pack 50 from moving under various possible external forces, and plays an important role in limiting and fixing the mounting piece 10, especially in the case of transportation or vibration. Moreover, through the cooperation of the second limiting groove 43 and the bottom plate 21 of the mounting frame 20, quick installation and disassembly can be achieved without the need for complex tools or additional component structures, simplifying the assembly process and facilitating maintenance or replacement when needed, thereby improving the operation and maintenance efficiency.

[0043] In the present application, through the cooperation of the second limiting piece 40 and the first limiting piece 30, the structural integrity of the entire fastening component can be significantly enhanced. The first limiting piece 30 and the second limiting piece 40 work in directions perpendicular to each other, forming a three-dimensional limiting network that reduces the freedom of movement of the battery pack 50 in various directions, thereby improving the rigidity and strength of the overall structure.

[0044] In the present embodiment, the second bent plate 41 is made of a plastic material, and the second limiting plate 42 is provided with a second stop portion 44 at an end thereof away from the second bent plate 41, and the bottom surface of the bottom plate 21 of the mounting frame 20 is provided with a second mounting protrusion 23, so that after the second limiting groove 43 is connected with the bottom plate 21 of the mounting frame 20, the second limiting plate 42 drives the second stop portion 44 to move to abut against the side of the second mounting protrusion 23 away from the second bent plate 41.

[0045] In this way, the second bending plate 41 made of plastic material can deform appropriately during installation to ensure that the second limiting groove 43 tightly fits the bottom plate 21 of the mounting frame 20. Once the second limiting groove 43 is clamped with the bottom plate 21 of the mounting frame 20, the second stop portion 44 will move to abut against the second mounting protrusion 23, forming a self-locking state, which effectively prevents the loosening of the mounting part 10 in the second direction even if it encounters vibration or temperature changes during transportation or operation, providing additional safety protection. Moreover, it helps to accurately align the second stop portion 44 with the second mounting protrusion 23 of the bottom plate 21 of the mounting frame 20 during assembly, ensuring that the second limiting groove 43 is firmly clamped with the bottom plate 21 of the mounting frame 20. This precise fit reduces the failure of the fixed structure caused by assembly errors, improving the reliability and stability of the fastening component. And makes the installation and disassembly process of the second limiting part 40 more simple, without the need for complex tools and operation procedures, just need to align the second limiting groove 43 with the second mounting protrusion 23, and then realize clamping or disassembly through plastic deformation, greatly facilitating the installation and maintenance work on site.

[0046] Optionally, the second bending plate 41 and the second limiting plate 42 are both made of steel material, and the second limiting groove 43 surrounded by the bottom surface of the second bending plate 41, the second limiting plate 42 and the first mounting plate 11 is clamped with the bottom plate 21 of the mounting frame 20 to limit the movement of the mounting part 10 in the second direction.

[0047] Optionally, the second bending plate 41 can be an arc-shaped plate or a right-angle plate, which can be adapted according to the end surface of the mounting frame 20 in the length direction.

[0048] As shown in Figures 1 to 3 The side plate 24 of the mounting frame 20 is provided with a plurality of first mounting holes 240, and the second mounting plate 12 is provided with a plurality of first connecting holes 120, which are correspondingly arranged one by one, so that the first connecting components are respectively arranged in the first connecting holes 120 and the first mounting holes 240, to relatively fix the second mounting plate 12 and the mounting frame 20. The above-mentioned first connecting components are bolt and nut structures. In this way, by arranging the first connecting components in the corresponding first mounting holes 240 and first connecting holes 120, the connection stability between the second mounting plate 12 and the mounting frame 20 is significantly enhanced, to ensure the accurate connection between the mounting part 10 and the mounting frame 20, thereby improving the installation accuracy of the whole fastening component. This accurate alignment can stably install the battery pack 50 in the bearing space, avoiding shaking and displacement caused by installation deviation.

[0049] In an example embodiment of the present application, the first mounting hole 240 is a strip-shaped hole extending along the length direction of the mounting frame 20, and the mounting member 10 can be adapted to different sizes of the battery pack 50 by adjusting the position of the first connecting member in the first mounting hole 240, and the battery pack 50 is stably fixed.

[0050] As shown in Figure 4 The housing of the component to be fixed is provided with a plurality of second mounting holes 51, and the third mounting plate 13 is provided with a plurality of second connecting holes 130, and the plurality of second mounting holes 51 and the plurality of second connecting holes 130 are correspondingly arranged, so that the second connecting member is respectively arranged in the second connecting hole 130 and the second mounting hole 51, so that the third mounting plate 13 is fixed relative to the component to be fixed. The second connecting member is a bolt and nut structure. In this way, by pre-providing the second mounting hole 51 and the second connecting hole 130 on the battery pack 50 housing and the third mounting plate 13, the assembly process becomes simpler and more intuitive, without the need for complex alignment, and only the second connecting member needs to be inserted into the corresponding hole to complete the fixing, which not only improves the assembly precision, but also reduces the assembly time and improves the overall efficiency. When the component to be fixed needs to be maintained or replaced, the fixing between the third mounting plate 13 and the battery pack 50 can be released only by disassembling the second connecting member, without the need to disassemble the entire fastening component, greatly simplifying the maintenance process, reducing the maintenance cost, and facilitating on-site operation.

[0051] Another aspect of the technical scheme of the present application provides a battery pack 50 structure, which comprises a battery pack 50, two mounting frames 20 and two fastening components mentioned above. The two fastening components are respectively arranged corresponding to the two mounting frames 20, and the fastening components are fixedly connected with the battery pack 50 and the mounting frame 20. In this way, by using the combination of the mounting member 10, the first limiting member 30 and the second limiting member 40 of the fastening component, the battery pack 50 is stably fixed on the two mounting frames 20, reducing the displacement and shaking caused by external factors such as vibration and impact during transportation or operation. The first limiting member 30 and the second limiting member 40 not only play a positioning role during installation, but also effectively prevent the loosening of the mounting member 10 during long-term use. Even in harsh environmental conditions, the stable fixing state of the battery pack 50 can be maintained, the safety risk caused by the failure of the fastening member is avoided, and the overall mechanical stability of the battery pack 50 structure is enhanced.

[0052] From the above description, it can be seen that the embodiments of the present application achieve the following technical effects:

[0053] The fastening component comprises the mounting piece 10 and the first limiting piece 30; the mounting piece 10 is used for being connected with the to-be-fixed component and the mounting rack 20 respectively, so as to fix the to-be-fixed component on the mounting rack 20; the first limiting piece 30 is connected with the mounting piece 10, and the first limiting piece 30 surrounds a first limiting part, and the first limiting part is connected with the mounting rack 20 in a matched mode, so as to limit the movement of the mounting piece 10 along the first direction. In this way, after the mounting piece 10 is connected with the mounting rack 20 and the to-be-fixed component respectively to fix the to-be-fixed component, the movement of the mounting piece 10 along the first direction is limited by the first limiting piece 30, so that the shaking and displacement of the to-be-fixed component and the loosening of the mounting piece 10 can be significantly reduced during the carrying process, so as to ensure the safe fixation of the to-be-fixed component, and thus the problem that the fixing structure of the battery pack 50 is prone to loosening and thus has low safety in the prior art is solved.
