Description

Technical Field

[0001] The invention relates to the technical field of battery supports, in particular to a lightweight external battery support. Background Art

[0002] The battery support is mainly composed of an inner battery support and an outer battery support. The inner battery support can further fix the battery and form a double support structure with the outer battery support, making the battery more stable during vehicle driving and reducing battery displacement caused by vibration, bumps, etc., thereby improving the reliability and safety of the battery system.

[0003] During the installation of the inner battery support on the outer battery support, the installation matching gap between the inner battery support and the outer battery support is small. The smaller installation gap can make the connection between the inner and outer battery supports tighter. During the driving of the vehicle, they can work together better and jointly bear the weight of the battery and various dynamic loads generated by the driving of the vehicle, thereby enhancing the strength and stability of the entire battery support structure and reducing structural deformation and looseness caused by vibration, bumps, etc.

[0048] Preferably, a circular positioning plate 7 for limiting the position of the support seat 102 is fixed inside the outer battery support box 101;

[0049] It should be noted here that: during the process of the support base 102 shrinking toward the inner side of the outer battery holder box 101, the support base 102 is abutted against the circular positioning plate 7 to position the shrinking support base 102 against each other.

[0050] In this solution: a lightweight external battery support includes the following steps:

[0051] When the outer battery holder is in use, the initial state of the support seat 102 is at the front side of the outer battery holder box 101, and the inner battery holder loaded with batteries is installed inside the outer battery holder box 101. During the installation process, the inner battery holder loaded with batteries is pushed toward the support seat 102. During the pushing process, the inner battery holder and the groups of balls 1003 on the front support plate 1002 of the support seat 102 are abutted against each other. Through the abutting support of the bottom of the inner battery holder by the groups of balls 1003, the installation position of the inner battery holder can be quickly adjusted. In the process of pushing and placing the inner battery holder, the placed inner battery holder is located between the groups of Z-shaped pressing plates 802.

[0052] After the inner battery holder is placed, the first threaded rod 401 is driven to rotate by the driving pin 403. During the rotation of the first threaded rod 401, the first threaded rod 401 and the first threaded tube 402 are meshed with each other to drive the mounting seat 2 to move under force. During the movement of the mounting seat 2, the two sets of first sleeves 501 and the first slide rod 502 are used to slide and guide the mounting seat 2 under force toward the inside of the outer battery holder box 101. During the movement of the mounting seat 2, the multiple sets of fixing rods 3 are used to connect and fix the support seat 102 and the inner battery holder placed on the support seat 102 to be retracted and installed toward the inside of the outer battery holder box 101.

[0053] During the movement of the support seat 102, as the first threaded rod 401 rotates, the second threaded rod 1101 is driven to rotate. During the rotation of the second threaded rod 1101, the second threaded rod 1101 and the second threaded tube 1102 are meshed with each other to drive the support plate 1002 to move under force. During the movement of the support plate 1002, the second sleeve 1201 and the second slide bar 1202 are used to slide and guide the support plate 1002 to retract toward the mounting seat 2. During the retraction of the mounting seat 2, each group of fixed plates 1301 is driven to move. During the movement of the fixed plate 1301, each group of Z-shaped pressing plates 802 is pulled together through the connecting plate 1302, so that each group of Z-shaped pressing plates 802 is close to the placing plate 2. After being placed, the inner battery support moves and is offset against the outer side of the inner battery support. The inner battery support is centrally positioned through the offsetting effect of each group of Z-shaped pressure plates 802 on the four sides of the inner battery support and the rolling support effect of each group of balls 1003 on the support plate 1002 on the inner battery support. The central positioning of the inner battery support facilitates the rapid installation of the inner battery support on the outer battery support, thereby improving the assembly and installation effect. Furthermore, through the continuous contraction movement of the support plate 1002, the inner battery support placed on the upper end of the support plate 1002 is finally offset against the top of the support seat 102. Through the offsetting support effect of the support seat 102 on the inner battery support, the stability of the inner battery support after positioning is maintained, thereby further ensuring the installation effect of the inner battery support on the outer battery support.
