具体实施方式detailed description
下面参照附图详细地说明本发明的具体实施方式。在各附图中，相同的附图标记表示相同或相应的技术特征。各附图仅为示意性的图示，并不一定按照实际比例绘制。Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the respective drawings, the same reference numerals indicate the same or corresponding technical features. The drawings are merely schematic representations and are not necessarily drawn to scale.
图1是根据本发明的一种实施方式的连接机构的第一部件的示意图。可以看出，在图示实施方式中，第一部件10可以包括连接杆体11和连接部12。二者可以是一体成型的，也可以是分别制成后再组装到一起。1 is a schematic illustration of a first component of a coupling mechanism in accordance with an embodiment of the present invention. It can be seen that in the illustrated embodiment, the first component 10 can include a connecting rod body 11 and a connecting portion 12. The two may be integrally formed or assembled separately and assembled together.
连接杆体11可以呈圆柱状，具有结构简单、易于加工等优点。在可选的实施方式中，连接杆体11也可以设置成具有其它形状的截面的柱状。例如但不限于多边棱柱状、椭圆柱状等。The connecting rod body 11 can have a cylindrical shape and has the advantages of simple structure, easy processing, and the like. In an alternative embodiment, the connecting rod body 11 can also be arranged in the shape of a column having a cross section of other shapes. For example, it is not limited to a polygonal prism shape, an elliptical column shape, or the like.
在图示实施方式中，连接部12位于连接杆体11的一端处。连接部12可以呈板状，并且被设置成双层连接板，相同层中的两个连接部12在周向上相对设置，不同层中的两个连接部12在轴向上对齐设置。In the illustrated embodiment, the connecting portion 12 is located at one end of the connecting rod body 11. The connecting portion 12 may be in the form of a plate and is provided as a double-layer connecting plate, and two connecting portions 12 of the same layer are disposed opposite each other in the circumferential direction, and two of the different layers 12 are aligned in the axial direction.
在可选的实施方式中，连接部12可以呈其它的形状，例如但不限于杆、销、片形状，以及球状凸起或不规则形状等。连接部12自连接杆体向外延伸的方向也不限于沿径向基本垂直于连接杆体延伸，可以具有一定的倾斜度等。连接部12可以一直沿远离连接杆体的中心轴线的方向延伸，也可以在延伸的过程中改变方向、甚至延伸成不规则形状，因为连接部12的向外延伸的至少一部分即能够实现与连接槽的接合。In alternative embodiments, the attachment portion 12 can take other shapes such as, but not limited to, a rod, a pin, a sheet shape, and a spherical projection or irregular shape or the like. The direction in which the connecting portion 12 extends outward from the connecting rod body is not limited to extending substantially perpendicular to the connecting rod body in the radial direction, and may have a certain inclination or the like. The connecting portion 12 may extend in a direction away from the central axis of the connecting rod body, or may change direction or even extend into an irregular shape during the extending process, because at least a part of the outward extension of the connecting portion 12 can be realized and connected to the connecting groove. Engagement.
在图示实施方式中共有四个连接部12。可以了解，根据具体需要，在其它实施方式中可以选择其它个数、其它层数的连接部，数量更多的情况下将增强连接的可靠性。在这种情况下，应当提供有相应层数的连接槽。可选地，连接部也可以设置在连接杆体的中间或沿连接杆体的纵向的其它适当部位，而不局限于图示的端部处。不同层的连接部12在轴向上可以相互对齐，也可以以适当的角度错开。连接部在连接杆体上可以沿周向均布；当设置有多层连接部时，不同层连接部可以都沿周向均布，并且各层之间的连接部可以沿轴向对齐。There are four connections 12 in the illustrated embodiment. It can be understood that, according to specific needs, other numbers and other number of connection points can be selected in other embodiments, and the reliability of the connection is enhanced in a larger number. In this case, a connection groove having a corresponding number of layers should be provided. Alternatively, the connecting portion may also be provided in the middle of the connecting rod body or other suitable portion in the longitudinal direction of the connecting rod body, and is not limited to the illustrated end portion. The connecting portions 12 of the different layers may be aligned with each other in the axial direction or may be shifted at an appropriate angle. The connecting portion may be uniformly distributed in the circumferential direction on the connecting rod body; when the plurality of connecting portions are provided, the different layer connecting portions may be uniformly distributed in the circumferential direction, and the connecting portions between the respective layers may be aligned in the axial direction.
在图示示例中，每层连接部12沿连接杆体11的轴向相互对齐。每个连接部12可以呈扇形，基本上垂直于连接杆体11且沿径向自连接杆体11的侧表面延伸。根据本发明的教示，所属领域的技术人员可以了解此处“基本上垂直”是清楚的，以使得连接部12能够可靠地与图2中第二部件中的连接槽24接合。此处，接合意指连接并可拆卸地结合或固定。 为了提高连接可靠性或拆卸的便利性，在可选的实施方式中，也可以将连接部设置成与连接杆体成适当的角度而不像图中所示基本垂直。In the illustrated example, each layer of the connecting portions 12 are aligned with each other in the axial direction of the connecting rod body 11. Each of the connecting portions 12 may be fan-shaped, substantially perpendicular to the connecting rod body 11 and extending radially from a side surface of the connecting rod body 11. In accordance with the teachings of the present invention, those skilled in the art will appreciate that "substantially vertical" is clear herein so that the connecting portion 12 can be reliably engaged with the connecting slot 24 in the second component of FIG. Here, the joint means that the joint is detachably coupled or fixed. In order to improve the reliability of the connection or the convenience of disassembly, in an alternative embodiment, the connecting portion may also be disposed at an appropriate angle to the connecting rod body rather than being substantially perpendicular as shown in the drawings.
另外，连接部的边缘13可以设置成斜角，例如沿连接杆体11的方向，连接部的厚度减小；连接部的侧面14则可以呈向着其进入端渐缩的锥形。此处，连接部的边缘13包括连接部的周向端侧处的边缘；连接部的侧面14包括连接部的周向端侧处的侧面。这些斜角和侧面的提供有利于为将第一部件10接合至第二部件20内提供引导作用。In addition, the edge 13 of the connecting portion may be provided at an oblique angle, for example, in the direction of the connecting rod body 11, the thickness of the connecting portion is reduced; the side surface 14 of the connecting portion may be tapered toward the entrance end thereof. Here, the edge 13 of the connecting portion includes an edge at the circumferential end side of the connecting portion; the side surface 14 of the connecting portion includes a side surface at the circumferential end side of the connecting portion. The provision of these bevels and sides facilitates guiding for engaging the first component 10 into the second component 20.
图2是根据本发明的前述实施方式的连接机构的第二部件的示意图。2 is a schematic view of a second component of a coupling mechanism in accordance with the aforementioned embodiments of the present invention.
可以看出，在图2所示的实施方式中，第二部件20包括连接壳体21。虽然图示示例中第二部件20的外形上呈圆形，但是，所属领域的技术人员可以了解，该第二部件的外形也可以呈其它任何形状，以适于在外部与另外的部件连接。It can be seen that in the embodiment shown in FIG. 2, the second component 20 includes a connection housing 21. Although the second member 20 is circular in shape in the illustrated example, those skilled in the art will appreciate that the shape of the second member may also be in any other shape suitable for external connection to additional components.
如图所示，连接壳体21内可以设置有进出通道和连接槽24。进出通道可以包括第一通道22和可选的第二通道23，其中，第一通道22用于供连接部通过，第二通道23用于供连接杆体通过，分别为它们提供进出通道。第一通道22和第二通道23的截面面积可以分别稍大于连接杆体和连接部的截面面积以使它们能够自由进出。As shown, an inlet and outlet passage and a connecting groove 24 may be provided in the connecting housing 21. The access channel may include a first channel 22 for the passage of the connection and a second channel 23 for the passage of the connecting rods, respectively providing access to them. The cross-sectional areas of the first passage 22 and the second passage 23 may be slightly larger than the cross-sectional areas of the connecting rod body and the connecting portion, respectively, to enable them to freely enter and exit.
在可选的实施方式中，可选的第二通道23在连接壳体21内可以是贯通的；当连接部12位于连接杆体的中间或沿连接杆体的纵向的其它适当部位而不位于图1所示的端部处时，连接杆体可以沿第二通道穿过连接壳体。在另一个可选的实施方式中，例如当连接部12的进入端延伸得高于连接杆体的端部时，可以不设置用于连接杆体的第二通道，而仅设置用于连接部的第一通道，此时不需要将连接杆体或其一部分伸入连接壳体内，而是连接部可以经过第一通道进入连接槽内，将第一部件和第二部件接合。In an alternative embodiment, the optional second passage 23 may be continuous in the connecting housing 21; when the connecting portion 12 is located in the middle of the connecting rod body or along other suitable portions in the longitudinal direction of the connecting rod body, it is not located in FIG. 1 At the end shown, the connecting rod body can pass through the connecting housing along the second passage. In another optional embodiment, for example, when the entrance end of the connecting portion 12 extends higher than the end of the connecting rod body, the second passage for connecting the rod body may not be provided, and only the first portion for the connecting portion may be provided. In one channel, there is no need to extend the connecting rod body or a portion thereof into the connecting housing at this time, but the connecting portion can enter the connecting groove through the first passage to engage the first member and the second member.
可以了解，由于连接部12安装在连接杆体11上，所以相应地第一通道22和第二通道23实际上可以是相通的，便于第一部件10在第二部件20内的操作。It will be appreciated that since the connecting portion 12 is mounted on the connecting rod body 11, the first passage 22 and the second passage 23 may be in fact in communication, facilitating the operation of the first member 10 within the second member 20.
第一通道22和可选的第二通道23与连接槽24是相通的，使得连接部12能够从第一通道22进入并接合至连接槽24。连接槽24的槽宽可以大于连接部12的厚度以保证连接部的旋转间隙。The first passage 22 and the optional second passage 23 are in communication with the connecting groove 24 such that the connecting portion 12 can enter from the first passage 22 and be joined to the connecting groove 24. The groove width of the connecting groove 24 may be larger than the thickness of the connecting portion 12 to secure a rotational gap of the connecting portion.
在图示实施方式中，连接槽24在连接壳体21内基本沿周向延伸，其与图1中的连接部12的设置能够实现一种实施方式中的连接机构的第一部件10和第二部件20的旋转接合，便于拆装操作。图中，连接槽24包括两层，分别适于接合图1中的两层连接部12。当连接杆体11上设置有其它层数(例如一层或者多于两层)的连接部12时，连接槽24的层数则可以设置有相应的一层或多于两层(或者更多)，从而适于连接部12进入并与其接合。In the illustrated embodiment, the connecting groove 24 extends substantially circumferentially within the connecting housing 21, and the arrangement of the connecting portion 12 in FIG. 1 enables the first component 10 and the first portion of the connecting mechanism in one embodiment. The rotational engagement of the two components 20 facilitates assembly and disassembly operations. In the figure, the connecting groove 24 comprises two layers which are respectively adapted to engage the two-layer connecting portion 12 in FIG. When the connecting rod body 11 is provided with other layers (for example, one layer or more than two layers), the number of layers of the connecting groove 24 may be set to a corresponding layer or more than two layers (or more). Thus, it is adapted to enter and engage the connecting portion 12.
可以理解，在图中所示的连接壳体21内，连接槽24包括图中能够看出的部分及位于其相对侧上的、在图中看不到的部分，这两部分在结构上可以是完全相同的。在可选的实施方式中，根据需要，可以设置有与连接杆件上的连接部的数量相应的更多段连接槽24。It can be understood that, in the connecting housing 21 shown in the drawing, the connecting groove 24 includes a portion which can be seen in the figure and a portion which is not visible on the opposite side of the drawing, and the two parts can be structurally It is exactly the same. In an alternative embodiment, more segments of connecting grooves 24 corresponding to the number of connections on the connecting bars may be provided as desired.
第一通道22和连接槽24可以围绕第二通道23的圆周方向排布；在不同的实施方式中，为了适应于连接杆体的圆周上连接部的个数，第一通道22和连接槽24的分段个数可以有所不同。为了防止连接部12在连接槽24内过度旋转而从其脱离，可以在连接槽24的一端设置有挡板25以实现限位作用，保证二者的可靠接合。The first passage 22 and the connecting groove 24 may be arranged around the circumferential direction of the second passage 23; in different embodiments, in order to accommodate the number of joints on the circumference of the connecting rod body, the first passage 22 and the connecting groove 24 The number of segments can vary. In order to prevent the connecting portion 12 from being excessively rotated in the connecting groove 24 and being detached therefrom, a baffle 25 may be provided at one end of the connecting groove 24 to achieve a limiting action to ensure reliable engagement of the two.
图2中的连接壳体21内的进出通道及连接槽24需与图1中的连接杆体11和连接部12的形状、结构、数量相适应。图中连接部12的扇形设计有利于增加与连接槽24的接合面积，加强接合可靠性；连接槽24内的接合面也可以具有相应的扇形设计。根据本申请的教示，所属领域的技术人员可以想到其它的常用形状，而不必局限于此；这将也落入本申请的范围内。The access passage and the connecting groove 24 in the connecting housing 21 in Fig. 2 are adapted to the shape, structure and number of the connecting rod body 11 and the connecting portion 12 in Fig. 1. The fan-shaped design of the connecting portion 12 in the drawing is advantageous for increasing the joint area with the connecting groove 24 and enhancing the joint reliability; the joint surface in the connecting groove 24 may also have a corresponding sector design. Other common shapes will occur to those skilled in the art in light of the teachings of the present application, and are not necessarily limited thereto; this will also fall within the scope of the present application.
图3至图6示出了包括图1中的第一部件和图2中的第二部件的连接机构。3 to 6 show a connection mechanism including the first member of Fig. 1 and the second member of Fig. 2.
图3和图4示出了第一部件和第二部件处于锁止位置。在图3和图4中，第一部件10的连接部12已进入到第二部件20的连接槽24内，并与其接合。此时，连接槽24的一端处设置的挡板25起到限定连接部12在连接槽24内的位置的作用，使连接部12停止在与连接槽24可靠连接处。如果没有该挡板25，则有可能连接部12会在连接槽24内移位过度而脱离与连接槽24的接合。可以看出，连接部12和连接槽24的接合将限制第一部件10和第二部件20沿连接杆体21轴向的相对移动。可以理解，如果有两个机构(例如动力电池和新能源交通工具的车身)分别固定至该第一部件10和该第二部件20，则这两个机构将被它们沿轴向相对固定位置。多个具有第一部件10和第二部件20的机构能够配合实现两个不同机构在多个自由度上的固定。Figures 3 and 4 show the first component and the second component in a locked position. In Figures 3 and 4, the connecting portion 12 of the first member 10 has entered and engaged with the connecting groove 24 of the second member 20. At this time, the baffle 25 provided at one end of the coupling groove 24 functions to define the position of the connecting portion 12 in the connecting groove 24, so that the connecting portion 12 is stopped at a reliable connection with the connecting groove 24. Without the baffle 25, there is a possibility that the connecting portion 12 will be excessively displaced in the connecting groove 24 to be disengaged from the engaging groove 24. It can be seen that the engagement of the connecting portion 12 and the connecting groove 24 will limit the relative movement of the first member 10 and the second member 20 in the axial direction of the connecting rod body 21. It will be appreciated that if two mechanisms, such as the power battery and the body of the new energy vehicle, are respectively secured to the first component 10 and the second component 20, the two mechanisms will be axially fixed relative to each other. A plurality of mechanisms having the first component 10 and the second component 20 can cooperate to achieve fixation of two different mechanisms in multiple degrees of freedom.
图5和图6示出了第一部件和第二部件处于未锁止位置。在图5和图6中，第一部件10上连接杆体11的相应端部以及连接部12均伸进第二部件20的连接壳体21内，并且连接部12位于连接壳体21的第一通道22(见图2)内、该端部位于连接壳体21的第二通道23(见图2)内。可以看出，此时第一部件10可以自由地从第二部件20内取出，使二者分离；也可以自由地旋转使得连接部12进入到连接槽24内(如图3和图4中所示)，使二者接合。Figures 5 and 6 show the first component and the second component in an unlocked position. In FIGS. 5 and 6, the respective ends of the connecting member 11 of the first member 10 and the connecting portion 12 both extend into the connecting housing 21 of the second member 20, and the connecting portion 12 is located at the first of the connecting housing 21. Inside the passage 22 (see Fig. 2), the end is located in the second passage 23 (see Fig. 2) of the connection housing 21. It can be seen that the first component 10 can be freely removed from the second component 20 at this time to separate the two components; it can also be freely rotated so that the connecting portion 12 enters the connecting groove 24 (as shown in FIGS. 3 and 4). Show), so that the two join.
此处再结合图1中所示，由于连接部12的边缘13设置成斜角或圆角，所以能够为连接部12旋转进入连接槽24时提供导向。依照图5和图6，在连接部12进入连接槽24 时，斜角或圆角的最窄的前端处先进入连接槽24，然后斜角的斜面或圆角的弧面引导连接部12进入连接槽24内，使得连接部12能够顺利地达到可靠的接合位置。Here, as further shown in FIG. 1, since the edge 13 of the connecting portion 12 is provided at an oblique angle or a rounded corner, it is possible to provide guidance when the connecting portion 12 is rotated into the connecting groove 24. According to FIGS. 5 and 6, when the connecting portion 12 enters the connecting groove 24, the narrowest front end of the bevel or rounded corner first enters the connecting groove 24, and then the beveled or rounded curved surface guides the connecting portion 12 into the connecting groove 12. The inside of the connecting groove 24 enables the connecting portion 12 to smoothly reach a reliable engaging position.
此处再结合图1中所示，连接部12的侧面14则可以呈向着连接杆体11的***端渐缩的锥形。依照图5可以看出，连接部12的上端由于渐缩而更细，所以作为连接杆体11上升时的导向，更易于将连接杆体11的***端插到连接壳体21的进出通道内。可以了解，在本上下文中的锥形不仅指每个连接部12的侧面14呈锥形，而且，在连接杆体11上具有多于一层的连接部12的实施方式中，也可以包括各层连接部12的侧面14整体上也构成锥形，如图5所示。在此特别指出，本申请中并不排除仅具有一层的连接部12的实施方式。As further shown herein in connection with FIG. 1, the side 14 of the connecting portion 12 can be tapered toward the insertion end of the connecting rod body 11. As can be seen from Fig. 5, the upper end of the connecting portion 12 is thinner due to the taper. Therefore, as the guide when the connecting rod body 11 is raised, it is easier to insert the insertion end of the connecting rod body 11 into the inlet and outlet passage of the connecting casing 21. It can be understood that the taper in this context means not only that the side surface 14 of each connecting portion 12 is tapered, but also that in the embodiment having more than one layer of the connecting portion 12 on the connecting rod body 11, each layer may also be included. The side surface 14 of the connecting portion 12 is also tapered as a whole, as shown in FIG. It is specifically noted herein that embodiments of the connection portion 12 having only one layer are not excluded from the present application.
所属领域的技术人员可以了解，在可选的实施方式中，连接杆体11也可以呈具有其它截面形状的柱体，而不必局限于图示的圆柱形连接杆体。如前文中所述，通过在连接杆体11的侧面形成有其它特征，例如但不限于螺纹等，可以通过连接杆体11将第一部件10连接到其它的机构；类似地，也可以通过连接壳体21将第二部件20固定到另外的机构。此时，通过将连接杆体11和连接壳体21接合则能够实现该其它的机构及该另外的机构的相对固定。It will be appreciated by those skilled in the art that in alternative embodiments, the connecting rod body 11 can also be in the form of a cylinder having other cross-sectional shapes, and is not necessarily limited to the illustrated cylindrical connecting rod body. As described in the foregoing, by forming other features on the side of the connecting rod body 11, such as but not limited to threads or the like, the first member 10 can be connected to other mechanisms by the connecting rod body 11; similarly, the connecting housing can also be connected 21 secures the second component 20 to another mechanism. At this time, the relative fixing of the other mechanism and the other mechanism can be achieved by joining the connecting rod body 11 and the connecting housing 21.
所属领域的技术人员可以了解，连接部12的层数可以设置成单层、两层或更多层、围绕连接杆体11的周向上的连接部的数量也可以变化。可以例如图所示的对置的两个连接部，也可以设置成仅有一个，也可以设置成多于两个。连接部12的位置和数量设计适于与连接壳体21中连接槽24的设计相适应。It will be understood by those skilled in the art that the number of layers of the connecting portion 12 may be set to be a single layer, two or more layers, and the number of connecting portions around the circumferential direction of the connecting rod body 11 may also vary. For example, the two opposite connecting portions shown in the figure may be provided in only one or in more than two. The position and number of the connections 12 are designed to accommodate the design of the connection slots 24 in the connection housing 21.
图7是根据本发明的一种实施方式的电池锁止装置的示意图。根据图示，电池锁止装置将电池框架60安装至车身，例如门槛30。在图中，在车身门槛30处设置有车身支架40，车身支架40通过螺栓50固定到车身门槛30。Figure 7 is a schematic illustration of a battery latching device in accordance with an embodiment of the present invention. According to the illustration, the battery locking device mounts the battery frame 60 to the vehicle body, such as the sill 30. In the figure, a body bracket 40 is provided at the body door sill 30, and the body bracket 40 is fixed to the body sill 30 by bolts 50.
本发明的一种连接机构的第二部件20的连接壳体例如以焊接等的方式固定至车身支架40，而第一部件10的连接杆体(见图9)则固定至电池框架60，通过将第一部件10的连接杆体接合到第二部件20的连接壳体即能够实现电池框架60至车身门槛30的安装，从而实现将动力电池装至新能源汽车。The connecting housing of the second component 20 of the connecting mechanism of the present invention is fixed to the vehicle body bracket 40, for example, by welding or the like, and the connecting rod body of the first component 10 (see FIG. 9) is fixed to the battery frame 60 by The connection of the connecting rod body of the first component 10 to the connecting housing of the second component 20 enables the mounting of the battery frame 60 to the body door sill 30, thereby enabling the power battery to be loaded into a new energy vehicle.
在实际应用中，可以通过在多个固定点使用这种电池锁止装置而将电池固定至汽车。根据电池的固定需要，这些固定点可以在例如但不限于汽车底盘处、汽车后备厢处、汽车前车舱处等不同位置。In practical applications, the battery can be secured to the vehicle by using such a battery lock at a plurality of fixed points. Depending on the need for the battery to be secured, these attachment points may be at various locations such as, but not limited to, a car chassis, a car trunk, a car front cabin, and the like.
