动力总成和用电装置

Abstract

本实用新型公开了一种动力总成和用电装置，动力总成包括：安装架、电池包和滚轮组件，安装架形成有多个安装位，安装架包括支撑杆，电池包沿第一方向在安装位置和取出位置之间可运动，滚轮组件设于电池包且包括多个滚轮机构，滚轮机构包括连接座和滚轮，连接座与电池包连接，滚轮可转动地设于连接座，滚轮沿第一方向可滚动地支撑于支撑杆。根据本实用新型的动力总成，通过在电池包上设置滚轮机构，可以较好地降低电池包沿第一方向在安装位置和取出位置之间运动的阻力，从而可以提升电池包的安装以及拆卸效率，并可以避免电池包在安装以及拆卸过程中产生的摩擦损伤。

Claims

1. A powertrain, characterized by, include: The mounting bracket has multiple mounting positions and includes a support rod. Battery pack The battery pack is movable between an installation position and a removal position along a first direction perpendicular to the vertical direction. In the installation position, the battery pack is located within the installation position, and in the removal position, at least a portion of the battery pack is located outside the mounting bracket. A roller assembly is disposed on the battery pack and includes multiple roller mechanisms. Each roller mechanism includes a connecting seat and a roller. The connecting seat is connected to the battery pack. The roller is rotatably disposed on the connecting seat. The rotation axis of the roller extends along a second direction, which is perpendicular to the first direction and the vertical direction. The roller is rotatably supported on the support rod along the first direction.

2. The powertrain of claim 1, wherein, The roller mechanism is detachably connected to the battery pack; and / or, the lower end of the roller is lower than the bottom surface of the battery pack.

3. The powertrain of claim 1, wherein, The roller is located on the side of the connector opposite to the battery pack; and / or, each roller mechanism includes a plurality of rollers, which are spaced apart along the first direction.

4. The powertrain of claim 1, wherein, The connector has a positioning post extending in the second direction, and the battery pack has a positioning hole, with the positioning post passing through the positioning hole.

5. The powertrain of claim 4, wherein, The positioning posts are arranged at intervals along the first direction. The connecting seat is also provided with a first connecting hole. The battery pack is formed with a second connecting hole. Fasteners are passed through the first connecting hole and the second connecting hole to fix the connecting seat. The multiple positioning posts are distributed on opposite sides of the connecting hole along the first direction; and / or, the cross-section of the positioning post is a rounded rectangle.

6. The powertrain of claim 1, wherein, The roller mechanism is located on one side of the battery pack along the second direction; and / or, both ends of the battery pack along the second direction are provided with a plurality of roller mechanisms arranged at intervals along the first direction.

7. The powertrain of claim 1, wherein, The mounting position is provided with a pick-and-place opening for removing or placing a battery pack on one side along the first direction. The roller mechanism also includes a guide plate. When moving from the removal position toward the mounting position, the guide plate is located on the side of the roller away from the pick-and-place opening. The side of the guide plate away from the roller is a guide surface. In the direction toward the pick-and-place opening, the guide surface extends obliquely away from the battery pack; and / or, a plurality of mounting positions are arranged in the vertical direction.

8. The powertrain of claim 1, wherein, The connecting seat has a lifting hole.

9. The powertrain of claim 8, wherein, The top of the connector has a protrusion, the lifting hole is formed on the protrusion, and the protrusion is located in the middle of the connector along the first direction.

10. An electrical device, characterized by include: The powertrain according to any one of claims 1-9.
