detailed description

The specific embodiment of the utility model is described in detail below with reference to accompanying drawing. In the drawings, the same reference numerals represent the same or corresponding technical features. The drawings are schematic illustrations only and are not necessarily drawn to scale.

Fig. 1 is a schematic diagram of a first part of a connection mechanism according to an embodiment of the present invention. It can be seen that, in the illustrated embodiment, the first component 10 may include a connecting rod body 11 and a connecting portion 12 . The two can be integrally formed, or they can be made separately and then assembled together.

The connecting rod body 11 can be cylindrical, which has the advantages of simple structure and easy processing. In an optional embodiment, the connecting rod body 11 may also be configured as a column with cross-sections of other shapes. For example but not limited to polygonal prism shape, ellipse column shape and so on.

In the illustrated embodiment, the connecting portion 12 is located at one end of the connecting rod body 11 . The connecting parts 12 may be in the shape of a plate, and are arranged as a double-layer connecting plate, two connecting parts 12 in the same layer are arranged opposite to each other in the circumferential direction, and two connecting parts 12 in different layers are aligned in the axial direction.

In an optional embodiment, the connection part 12 may be in other shapes, such as but not limited to rods, pins, pieces, and spherical protrusions or irregular shapes. The direction in which the connecting portion 12 extends outward from the connecting rod body is not limited to extend radially and substantially perpendicular to the connecting rod body, and may have a certain inclination. The connecting portion 12 can always extend in a direction away from the central axis of the connecting rod body, and can also change direction during the extension process, or even extend into an irregular shape, because at least a part of the connecting portion 12 extending outward can realize the connection with the connecting groove. of joining.

In the illustrated embodiment, there are four connection portions 12 in total. It can be understood that, according to specific needs, in other implementation manners, other numbers and layers of connecting parts can be selected, and a larger number will enhance the reliability of the connection. In this case, connection slots with a corresponding number of layers should be provided. Optionally, the connecting portion may also be arranged in the middle of the connecting rod body or at other suitable positions along the longitudinal direction of the connecting rod body, not limited to the illustrated end portion. The connecting portions 12 of different layers may be aligned with each other in the axial direction, or may be staggered at an appropriate angle. The connecting parts can be evenly distributed along the circumferential direction on the connecting rod body; when multi-layer connecting parts are provided, the connecting parts of different layers can be uniformly distributed along the circumferential direction, and the connecting parts between the layers can be aligned in the axial direction.

In the illustrated example, the connecting portions 12 of each layer are aligned with each other along the axial direction of the connecting rod body 11 . Each connecting portion 12 may be fan-shaped, substantially perpendicular to the connecting rod body 11 and extending from a side surface of the connecting rod body 11 in a radial direction. According to the teaching of the present invention, those skilled in the art can understand that "substantially vertical" here is clear, so that the connecting portion 12 can reliably engage with the connecting groove 24 in the second component in FIG. 2 . Here, engaging means being connected and detachably coupled or fixed. In order to improve the reliability of the connection or the convenience of disassembly, in an optional embodiment, the connection part may also be arranged to form an appropriate angle with the connecting rod body instead of being substantially vertical as shown in the figure.

In addition, the edge 13 of the connection part can be set at an oblique angle, for example, the thickness of the connection part decreases along the direction of the connecting rod body 11; the side surface 14 of the connection part can be tapered toward its entry end. Here, the edge 13 of the connection part comprises the edge at the circumferential end side of the connection part; the side face 14 of the connection part comprises the side surface at the circumferential end side of the connection part. The provision of these bevels and sides advantageously provides guidance for engaging the first part 10 into the second part 20 .

Fig. 2 is a schematic diagram of the second part of the connection mechanism according to the previous embodiment of the present invention.

It can be seen that, in the embodiment shown in FIG. 2 , the second component 20 comprises a connection housing 21 . Although the shape of the second component 20 in the illustrated example is circular, those skilled in the art can understand that the shape of the second component can also be any other shape, so as to be suitable for external connection with other components.

As shown in the figure, an access channel and a connection groove 24 may be provided in the connection housing 21 . The access channel may include a first channel 22 and an optional second channel 23 , wherein the first channel 22 is used for the passage of the connecting part, and the second channel 23 is used for the passage of the connecting rod body, providing access to them respectively. 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 so that they can enter and exit freely.

In an optional embodiment, the optional second channel 23 can be through in the connecting housing 21; At the end shown, the connecting rod can pass through the connecting housing along the second channel. In another optional embodiment, for example, when the inlet end of the connecting part 12 extends higher than the end of the connecting rod body, the second channel for connecting the rod body may not be provided, but only the first passage for the connecting part may be provided. One channel, at this time, it is not necessary to extend the connecting rod body or a part thereof into the connecting housing, but the connecting part can pass through the first channel and enter the connecting groove to join the first component and the second component.

It can be understood that since the connecting portion 12 is installed on the connecting rod body 11 , correspondingly, the first passage 22 and the second passage 23 can actually communicate, which facilitates the operation of the first component 10 in the second component 20 .

The first channel 22 and the optional second channel 23 communicate with the connecting groove 24 , so that the connecting part 12 can enter and engage with the connecting groove 24 from the first channel 22 . The width of the connection groove 24 may be greater than the thickness of the connection part 12 to ensure the rotation clearance of the connection part.

In the illustrated embodiment, the connecting groove 24 extends substantially along the circumferential direction in the connecting housing 21, and its arrangement with the connecting portion 12 in FIG. The rotation joint of the two components 20 is convenient for disassembly and assembly operations. In the figure, the connection groove 24 includes two layers, which are respectively suitable for joining the two layers of the connection portion 12 in FIG. 1 . When the connecting rod body 11 is provided with other layers (such as one or more than two layers) of connecting parts 12, the layers of the connecting groove 24 can be provided with corresponding one or more than two layers (or more) , so that it is suitable for the connecting part 12 to enter and engage with it.

It can be understood that in the connection housing 21 shown in the figure, the connection groove 24 includes a part that can be seen in the figure and a part that is located on the opposite side and cannot be seen in the figure. These two parts can be structurally are exactly the same. In an optional embodiment, as required, more connecting grooves 24 corresponding to the number of connecting parts on the connecting rod may be provided.

The first channel 22 and the connecting groove 24 can be arranged around the circumferential direction of the second channel 23; The number of segments can vary. In order to prevent the connecting part 12 from over-rotating in the connecting groove 24 and disengaging from it, a baffle plate 25 may be provided at one end of the connecting groove 24 to realize a position-limiting effect and ensure reliable engagement of the two.

The access channel and connecting groove 24 in the connecting housing 21 in FIG. 2 need to be compatible with the shape, structure and quantity of the connecting rod body 11 and the connecting portion 12 in FIG. 1 . The fan-shaped design of the connecting part 12 in the figure is beneficial to increase the joint area with the connecting groove 24 and enhance the reliability of the connection; the joint surface in the connecting groove 24 may also have a corresponding fan-shaped design. According to the teaching of the present application, those skilled in the art can think of other commonly used shapes without being limited thereto; this will also fall within the scope of the present application.

3 to 6 show a connection mechanism comprising the first component in FIG. 1 and the second component in FIG. 2 .

Figures 3 and 4 show the first part and the second part in a locked position. In FIGS. 3 and 4 , the connection portion 12 of the first component 10 has entered into the connection groove 24 of the second component 20 and engaged therewith. At this time, the baffle plate 25 provided at one end of the connecting groove 24 functions to limit the position of the connecting portion 12 in the connecting groove 24 , so that the connecting portion 12 stops at a reliable connection with the connecting groove 24 . If there is no baffle plate 25 , there is a possibility that the connecting portion 12 will be displaced excessively in the connecting groove 24 and be out of engagement with the connecting groove 24 . It can be seen that the engagement of the connecting portion 12 and the connecting groove 24 will restrict the relative movement of the first component 10 and the second component 20 along the axial direction of the connecting rod body 21 . It can be understood that if there are two mechanisms (such as a power battery and a vehicle body of a new energy vehicle) fixed to the first component 10 and the second component 20 respectively, the two mechanisms will be relatively fixed in position by them in the axial direction. Multiple mechanisms with the first component 10 and the second component 20 can cooperate to realize the fixation of two different mechanisms in multiple degrees of freedom.

Figures 5 and 6 show the first part and the second part in the unlocked position. In Fig. 5 and Fig. 6, the corresponding ends of the connecting rod body 11 on the first part 10 and the connecting part 12 all protrude into the connecting housing 21 of the second part 20, and the connecting part 12 is located at the first end of the connecting housing 21. In the channel 22 (see FIG. 2 ), the end is located in the second channel 23 (see FIG. 2 ) connecting the housing 21 . It can be seen that at this moment, the first component 10 can be freely taken out from the second component 20 to separate the two; it can also be freely rotated so that the connecting portion 12 enters the connecting groove 24 (as shown in Figures 3 and 4 ). shown) to connect the two.

Referring again to what is shown in FIG. 1 , since the edge 13 of the connecting portion 12 is set at a bevel or rounded corner, it can provide a guide for the connecting portion 12 to rotate into the connecting groove 24 . According to Figure 5 and Figure 6, when the connecting part 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 arc guides the connecting part 12 into In the connection groove 24, the connection part 12 can smoothly reach a reliable joint position.

Referring again to what is shown in FIG. 1 , the side surface 14 of the connecting portion 12 can be in a tapered shape that tapers 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 tapering, so as a guide when the connecting rod body 11 rises, it is easier to insert the insertion end of the connecting rod body 11 into the access channel of the connecting housing 21 . It can be understood that the conical shape in this context not only means that the side 14 of each connecting portion 12 is tapered, but also may include various layers in the embodiment in which there are more than one layer of connecting portions 12 on the connecting rod body 11. The side surface 14 of the connecting portion 12 is also conical as a whole, as shown in FIG. 5 . It is particularly pointed out here that the present application does not exclude embodiments with only one layer of the connecting portion 12 .

Those skilled in the art can understand that, in an optional embodiment, the connecting rod body 11 can also be a cylinder with other cross-sectional shapes, and is not limited to the illustrated cylindrical connecting rod body. As mentioned above, by forming other features on the side of the connecting rod body 11, such as but not limited to threads, the first component 10 can be connected to other mechanisms through the connecting rod body 11; 21 secures the second part 20 to a further mechanism. At this time, the other mechanism and the relative fixation of the other mechanism can be realized by joining the connecting rod body 11 and the connecting housing 21 .

Those skilled in the art can understand that the number of layers of the connecting part 12 can be set as a single layer, two or more layers, and the number of connecting parts around the circumference of the connecting rod body 11 can also be changed. For example, there may be two opposite connecting parts as shown in the figure, or there may be only one connection part, or there may be more than two connection parts. The design of the position and quantity of the connecting parts 12 is adapted to match the design of the connecting groove 24 in the connecting housing 21 .
