目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅 被应用于水力、火力、风力和太阳能电站等储能电源***，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。At present, judging from the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only It is used in energy storage power systems such as hydraulic, thermal, wind and solar power stations, and is also widely used in electric vehicles such as electric bicycles, electric motorcycles and electric cars, as well as in many fields such as military equipment and aerospace. As the application fields of power batteries continue to expand, their market demand is also constantly expanding.
T型套筒作为动力电池型材箱体常用的挂载结构，T型套筒与型材边框的连接方式可为焊接、过盈或者粘接。本申请发明人注意到，由于电池包的整体尺寸和重量较大，在电动汽车行驶经过路况较差的路面时，车架会受到较大的振动冲击。对于焊接，常常会因为出现振动及冲击工况而导致连接处开裂，且焊接时T型套筒的焊接处需要打磨光滑，整个工艺过程较为繁琐。对于过盈粘接，衬套的方向拔脱力大小取决于过盈量大小及粘接强度，较大的过盈量会导致衬套接触的边框面塌陷变形甚至开裂，较小的过盈量又会导致衬套的方向拔脱力过小，且过盈量控制难度大，安装困难。对于粘接，涂胶工艺繁琐，在吊装工况还经常会出现衬套脱落或结构胶开裂的情况。The T-shaped sleeve is a commonly used mounting structure for power battery profile boxes. The connection method between the T-shaped sleeve and the profile frame can be welding, interference or bonding. The inventor of the present application noticed that due to the large overall size and weight of the battery pack, when the electric vehicle drives on a road with poor road conditions, the frame will be subject to large vibration impacts. For welding, the joints often crack due to vibration and impact conditions, and the welding joint of the T-shaped sleeve needs to be polished smooth during welding, making the entire process cumbersome. For interference bonding, the directional pull-out force of the bushing depends on the interference amount and the bonding strength. A larger interference amount will cause the frame surface in contact with the bushing to collapse, deform or even crack, while a smaller interference amount will cause the bushing to contact the frame surface. This will cause the directional pull-out force of the bushing to be too small, make it difficult to control the interference, and make installation difficult. For bonding, the glue application process is cumbersome, and bushings often fall off or structural glue cracks during hoisting conditions.
因此，本申请的实施例提供了一种挂载结构100，其安装方式简单，且连接稳固可靠。请参照图1和图3，挂载结构100包括嵌套件10和弹片20。请参照图2和图9，安装时，嵌套件10卡接在型材200的镶嵌孔220内，弹片20则抵接在嵌套件10的法兰面和型材200之间。Therefore, the embodiment of the present application provides a mounting structure 100 with a simple installation method and a stable and reliable connection.

One end of the sleeve 12 is fixed to the sleeve 11. In order to make the appearance beautiful and facilitate the production, when the sleeve 11 is fixed to the sleeve 12, the axes of the two coincide with each other.
套筒12的外表面则设置有限位台121，限位台121与套帽11之间具有间隙空间，该间隙空间可用于安装弹片20并用于夹持型材200等安装部件(后续安装部件均以型材200为例)。可以理解的是，限位台121的外形轮廓可自由设置，例如、长方体状、梯形状、柱状等，限位台121的数量也可根据实际需要进行设置，可设置为一个、两个或者多个，通常情况下，为保证夹持稳定，限位台121的数量通常不低于两个；需要说明的是，为保证夹持稳定，限位台121朝向套帽11的端面为平面，该平面与型材200的平面相抵接，以保证限位台121与型材200之间具有较大的压接面积。The outer surface of the sleeve 12 is provided with a limiting platform 121. There is a gap space between the limiting platform 121 and the sleeve cap 11. This gap space can be used to install the spring piece 20 and to clamp the profile 200 and other installation components (subsequent installation components are all Profile 200 as an example). It can be understood that the outline of the limiting platform 121 can be freely set, for example, rectangular, trapezoidal, columnar, etc., and the number of the limiting platform 121 can also be set according to actual needs, and can be set to one, two or more. Normally, in order to ensure stable clamping, the number of limiting platforms 121 is usually not less than two; it should be noted that, in order to ensure stable clamping, the end surface of the limiting platform 121 facing the cap 11 is a flat surface. The flat surface is in contact with the flat surface of the profile 200 to ensure a large pressing area between the limiting platform 121 and the profile 200 .

The elastic piece 20 can be arranged in a flat ring shape. The annular elastic piece 20 is sleeved on the outer surface of the sleeve 12, and the elastic piece 20 is connected to the sleeve cap 11 toward the limiter. On the end face of the platform 121, the elastic piece 20 can be made of metal material or plastic material. It can be understood that in order to reduce the radial looseness of the elastic piece 20 on the sleeve 12, the inner diameter of the elastic piece 20 should be set to be equal to the outer diameter of the sleeve 12 as much as possible.
弹片20与限位台121之间具有预设间隙，该预设间隙用于夹持型材200的一个侧壁。为减缓型材200与嵌套件10之间的振动，弹片20朝背离套帽11的方向延伸有弹性部件22。安装时，型材200抵接在弹片20的弹性部件22和套筒12的限位台121之间，套帽11对弹片20起到限位固定的作用，使得挂载结构100卡接于型材200上，弹性部件22起到缓冲作用，可减缓吊装或运输时的振动，以保证挂载连接稳定。需要说明的是，由于弹性部件22的存在，沿套筒12的轴向，弹片20与限位台121之间的预设间隙的宽度通常略大于型材200被夹持位置的厚度。There is a preset gap between the elastic piece 20 and the limiting platform 121, and the preset gap is used to clamp one side wall of the profile 200. In order to slow down the vibration between the profile 200 and the nesting member 10 , the elastic piece 20 has an elastic component 22 extending in a direction away from the sleeve 11 . During installation, the profile 200 is in contact between the elastic component 22 of the elastic piece 20 and the limiting platform 121 of the sleeve 12 , and the sleeve cap 11 plays a role in limiting and fixing the elastic piece 20 , so that the mounting structure 100 is engaged with the profile 200 On the top, the elastic component 22 plays a buffering role, which can slow down the vibration during hoisting or transportation to ensure the stability of the mounting connection. It should be noted that due to the existence of the elastic component 22, along the axial direction of the sleeve 12, the width of the preset gap between the elastic piece 20 and the limiting platform 121 is usually slightly larger than the thickness of the clamped position of the profile 200.
通过设置弹性部件22，可减缓套筒12的上下串动，且可有效防止安装部件与套帽11直接发生碰撞，以保护挂载结构100和安装部件；同时，安装部 件可直接夹持在弹片20和限位台121之间，通过套帽11和限位台121对安装部件进行限位，安装方便且夹持稳固。By providing the elastic component 22, the up and down movement of the sleeve 12 can be slowed down, and direct collision between the mounting component and the cap 11 can be effectively prevented to protect the mounting structure 100 and the mounting component; at the same time, the mounting part The component can be directly clamped between the elastic piece 20 and the limiting platform 121, and the installation component is limited through the cap 11 and the limiting platform 121, making the installation easy and the clamping stable.
可以理解的是，为便于安装，型材200的镶嵌孔220上可对应设置供限位台121进入的限位槽230，限位台121可直接从限位槽230进入至镶嵌孔220内，再通过旋转嵌套件10至预定位置，使得型材200被夹持于限位台121和弹片20之间。It can be understood that, in order to facilitate installation, the inlay hole 220 of the profile 200 can be provided with a limit groove 230 for the limit table 121 to enter, and the limit table 121 can directly enter the inlaid hole 220 from the limit groove 230, and then By rotating the nesting member 10 to a predetermined position, the profile 200 is clamped between the limiting platform 121 and the elastic piece 20 .
而由于套筒12通常会设置为圆柱状，在套筒12嵌入至型材200的镶嵌孔220内时，套筒12难免会再发生旋转而导致连接不稳固。因此，为防止套筒12与型材200发生相对旋转，在一些实施例中，请参照图5-图7，挂载结构100还包括防转限位弹扣21，防转限位弹扣21与弹片20连接，且防转限位弹扣21朝背离套帽11的方向延伸。当嵌套件10在型材200的镶嵌孔220内旋转时，防转限位弹扣21则在型材200的外表面沿镶嵌孔220的边沿旋转，而限位槽230可设置在镶嵌孔220的边沿，当嵌套件10在镶嵌孔220内旋转至预定位置时，防转限位弹扣21则刚好卡接在限位槽230内，以防止嵌套件10与型材200发生相对转动。为提高防转限位弹扣21的强度，防转限位弹扣21可与弹片20一体成型设置。Since the sleeve 12 is usually set in a cylindrical shape, when the sleeve 12 is embedded in the inlaid hole 220 of the profile 200, the sleeve 12 will inevitably rotate again, resulting in an unstable connection. Therefore, in order to prevent relative rotation between the sleeve 12 and the profile 200, in some embodiments, please refer to Figures 5 to 7, the mounting structure 100 also includes an anti-rotation limit buckle 21, and the anti-rotation limit buckle 21 and The elastic pieces 20 are connected, and the anti-rotation limiting elastic buckle 21 extends in a direction away from the sleeve cap 11 . When the nesting member 10 rotates in the mounting hole 220 of the profile 200, the anti-rotation limiting spring buckle 21 rotates on the outer surface of the profile 200 along the edge of the mounting hole 220, and the limiting groove 230 can be provided at the edge of the mounting hole 220. On the edge, when the nesting piece 10 rotates to a predetermined position in the inlay hole 220, the anti-rotation limiting spring buckle 21 just snaps into the limiting groove 230 to prevent the nesting piece 10 and the profile 200 from rotating relative to each other. In order to improve the strength of the anti-rotation limit buckle 21, the anti-rotation limit buckle 21 can be integrally formed with the elastic piece 20.
对于弹性部件22，其可选择不同的形状以及不同的与弹片20的连接方式。在一些实施例中，请参照图5和图6，弹性部件22倾斜设置于弹片20上，弹性部件22可设置为长条状，其两端为别为第一端和第二端，第一端固定于弹片20背离套帽11的端面，第二端则向远离弹片20的方向倾斜延伸。当朝弹片20的方向按压弹性部件22的第二端时，第二端则朝弹性部件22靠拢，以产生朝远离弹片20方向的弹性力。For the elastic component 22, different shapes and different connection methods with the elastic piece 20 can be selected. In some embodiments, please refer to FIGS. 5 and 6 , the elastic member 22 is disposed obliquely on the elastic piece 20 . The elastic member 22 can be disposed in a strip shape, with two ends respectively being a first end and a second end. The first end is fixed to the end surface of the elastic piece 20 facing away from the cap 11 , and the second end extends obliquely in a direction away from the elastic piece 20 . When the second end of the elastic member 22 is pressed toward the elastic piece 20 , the second end moves closer to the elastic member 22 to generate an elastic force in a direction away from the elastic piece 20 .
由于弹性部件22朝远离弹片20的方向延伸，其会占据一定的空间，在型 材200的一个侧壁被夹持在弹片20和限位台121之间时，弹性部件22也会占据一定的空间。因此，在一些实施例中，请参照图5-图6，为减少弹性部件22所占用的空间，弹片20设有第一收容孔23，弹性部件22被压缩时，可直接全部收容或部分收容在该第一收容孔23内。具体的，弹性部件22的一端连接于第一收容孔23的内壁或边沿，在弹性部件22受到朝向弹片20的压力时，弹性部件22的至少部分收容于第一收容孔23。需要说明的是，第一收容孔23可贯穿弹片20，也可不贯穿弹片20，可根据具体的需求进行设置。Since the elastic component 22 extends in a direction away from the elastic piece 20, it will occupy a certain space. When one side wall of the material 200 is clamped between the elastic piece 20 and the limiting platform 121, the elastic component 22 will also occupy a certain space. Therefore, in some embodiments, please refer to Figures 5-6. In order to reduce the space occupied by the elastic member 22, the elastic piece 20 is provided with a first receiving hole 23. When the elastic member 22 is compressed, it can be directly received in full or partially. in the first receiving hole 23 .

It should be noted that the first receiving hole 23 may or may not penetrate the elastic piece 20 , and may be set according to specific requirements.
可以理解的是，为提高弹性部件22对型材200的弹性力，弹性部件22可设置为多个；而由于嵌套件10在安装至型材200的镶嵌孔220内时，需要旋转至预定位置，当弹性部件22的倾斜方向与嵌套件10的旋转方向相同时，弹性部件22就会与型材200的表面产生较大的摩擦。为防止弹性部件22对嵌套件10的旋转造成干涉，多个弹性部件22均朝弹片20周向的同一个方向倾斜。可以理解的是，嵌套件10需要顺时针旋转时，全部弹性部件22则沿逆时针方向倾斜设置。It can be understood that in order to improve the elastic force of the elastic component 22 on the profile 200, multiple elastic components 22 can be provided; and since the nesting member 10 needs to be rotated to a predetermined position when being installed into the inlaid hole 220 of the profile 200, When the inclination direction of the elastic member 22 is the same as the rotation direction of the nesting member 10 , the elastic member 22 will generate greater friction with the surface of the profile 200 . In order to prevent the elastic members 22 from interfering with the rotation of the nesting member 10 , the plurality of elastic members 22 are inclined in the same circumferential direction of the elastic piece 20 . It can be understood that when the nesting member 10 needs to rotate clockwise, all the elastic members 22 will be inclined in the counterclockwise direction.
根据本申请的一些实施例，弹性部件22也可垂直设置在弹片20上，需要说明的是，本实施例的中垂直设置是指弹性部件22的轴线与弹片20的表面垂直。According to some embodiments of the present application, the elastic member 22 can also be arranged vertically on the elastic piece 20. It should be noted that the vertical arrangement in this embodiment means that the axis of the elastic member 22 is perpendicular to the surface of the elastic piece 20.
垂直设置的弹性部件22也会占据一定空间，因此，在一些实施例中，请参照图7，弹性部件22上设有第二收容孔24，第二收容孔24用于收容弹性部件22。具体的，弹性部件22为柱状，柱状的弹性部件22与弹片20垂直，弹性部件22一端固定连接于第二收容孔24内，另一端则延伸于第二收容孔24外。当弹性部件22被压缩时，弹性部件22会全部或部分收容于第二收容孔24内。为便于弹性部件22沿垂直于弹片20的方向进入第二收容孔24，第二 收容孔24的轴向也与弹片20垂直。可以理解的是，垂直设置的弹性部件22，当弹性部件22被压缩时，其弹性力的方向与弹片20垂直，以便于向型材200提供较大的弹性力。The vertically arranged elastic component 22 will also occupy a certain space. Therefore, in some embodiments, please refer to FIG. 7 , the elastic component 22 is provided with a second receiving hole 24 , and the second receiving hole 24 is used to receive the elastic component 22 . Specifically, the elastic member 22 is columnar, and the columnar elastic member 22 is perpendicular to the elastic piece 20 .
