Detailed Description
Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application unless it is specifically stated otherwise.
The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application, its application, or uses.
Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of exemplary embodiments may have different values.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
Referring to fig. 1 and 2, a battery tray 100 includes: a first side beam 101, wherein the first side beam 101 has a first deformation block 102 and a second deformation block 103, and a space 104 exists between the first deformation block 102 and the second deformation block 103; a second side beam 105, the second side beam 105 having a first through hole 106, the first deformation block 102 and the second deformation block 103 being inserted into the first through hole 106; the wedge block 107 is inserted into the space 104, the wedge block 107 extrudes the first deformation block 102 and the second deformation block 103, the first deformation block 102 and the second deformation block 103 are deformed after extrusion, the first deformation block 102 and the second deformation block 103 are fixed in the first through hole 106, and the first side beam 101 and the second side beam 105 are connected together by utilizing the principle of a mortise and tenon structure. At this time, even if welding is not performed any more, the first deformation block 102, the second deformation block 103, and the wedge block 107 can function as a good fixed connection. When the welding is performed again to improve the connection reliability, the problems of welding slag, high-temperature deformation, inconvenience in subsequent polishing and the like can be significantly reduced compared with the direct splicing welding of two side beams due to the existence of the first deformation block 102, the second deformation block 103 and the wedge block 107. An annular gasket 116 is provided between the first side rail 101 and the second side rail 105, and the annular gasket 116 surrounds the first deformation block 102 and the second deformation block 103. After assembly, the annular gasket 116 seals at the first through hole 106, improving sealing performance.
Referring to fig. 3, the figure schematically illustrates the shape of the first through hole in a cross-sectional view. The left side in fig. 3 is the side closer to the first side rail 101, and the right side is the side farther from the first side rail 101. As can be seen from fig. 3, the first through hole 106 is a tapered hole, and the length L1 of the side near the first side beam 101 is smaller than the length L2 of the side far from the first side beam 101. The advantage of this structure is that the wedge block 107 is inserted into the space 104 at a side far from the first side beam 101, and after the first deformation block 102 and the second deformation block 103 are pressed by the wedge block 107, the deformation is generated in the up and down directions in fig. 3, so as to hook the second side beam 105, so that the connection between the first side beam 101 and the second side beam 105 is more reliable.
Referring to fig. 4, a schematic view is obtained by observing the first through hole 106 of the second side sill 102 from the side away from the first side sill 101. In a state in which the wedge block 107 is not inserted, the length L2 of the first through hole 106 is greater than the length L3 between the upper end face of the first deformation block 102 and the lower end face of the second deformation block 103. The advantage of this construction is that sufficient deformation space can be given to the first deformation block 102 and the second deformation block 103, so that the connection between the first side rail 101 and the second side rail 105 is more reliable, and the second side rail 105 is excessively pressed after the insertion of the mode wedge block 107, resulting in tearing thereof.
Referring to fig. 5, the width W1 of the first through hole 106 is larger than the width W2 of the second deformation block 103, and similarly, the width W1 of the first through hole 106 is also larger than the width of the first deformation block 102 and the width of the wedge block 107. That is, the width W1 of the first through hole 106 is the largest among the four first through hole 106, the first deformation block 102, the second deformation block 103, and the wedge block 107. This configuration has the advantage that, on the one hand, the insertion of the wedge 107 is easy and, on the other hand, the redundant width space of the first through hole 106 is able to receive more solder filling when soldering is required, so that a better soldering strength is obtained.
Alternatively, in a state where the wedge block 107 is not inserted, a length difference between the length L2 of the first through hole 106 and the length L3 between the upper end surface of the first deformation block 102 and the lower end surface of the second deformation block 103 is larger than a width difference between the width W1 of the first through hole 106 and the width of the first deformation block 102 or the second deformation block 103 or the wedge block 107 on the side away from the first side beam 101. In other words, the gaps between the first deformation block 102, the second deformation block 103, and the second side beam 105 in the length direction of the first through hole 106 are larger than the gaps between the first deformation block 102 or the second deformation block 103 or the wedge block 107 and the second side beam 105 in the width direction of the first through hole 106. This structure has an advantage in that the first deformation block 102 and the second deformation block 103 can be deformed in the up-down direction as much as possible, thereby improving connection reliability.
As can be seen from fig. 1, the first side beam 101 is further provided with a lightening hole 108, and the lightening hole 108 is located at a position where the first deformation block 102 and the second deformation block 103 are combined with the main body of the first side beam 101. The advantage of having the lightening hole at this position is that it can not only perform the lightening function, but also weaken the local strength of the first side beam 101, making the first deformation block 102 and the second deformation block 103 more prone to deformation.
Optionally, the battery tray 100 further includes a first middle beam 109 and a second middle beam 111, which are crossed in the lateral direction to partition the plurality of battery receiving spaces 113. The second side beam 105 is provided with a second through hole 110, and the first intermediate beam 109 has a protruding portion 112, and the protruding portion 112 is inserted into the second through hole 110. This manner of attachment of the first center sill 109 to the second side sill 105 allows for easier installation. Similarly, the second intermediate beam 111 may have a protruding portion 112, and accordingly, the first side beam 101 may be provided with a second through hole 110, and the second intermediate beam 111 and the first side beam 101 may be connected in a plugging manner.
Referring to fig. 6, when the wedge block 107 is not inserted into the space 104, the first deformation block 102 and the second deformation block 103 are in an undeformed state, and at this time, the inner edge 117 of the annular seal 116 abuts against the first deformation block 102 and the second deformation block 103, which has an advantage in that the junction of the first deformation block 102 and the second deformation block 103 with the first through hole 106 can be ensured to be completely sealed.
Referring to fig. 7, when the wedge-shaped block 107 is inserted into the space 104, the first deformation block 102 and the second deformation block 103 are in a deformed state, and at this time, the deformation generated by the edges of the first deformation block 102 and the second deformation block 103 is shown by the dotted line, and accordingly, the first deformation block 102 and the second deformation block 103 apply an expansion force to the inner edge 117 of the annular gasket 116, so that the inner edge 117 is also deformed, and a tendency of expanding toward the outer edge 118 of the annular gasket 116 occurs. The advantage of this construction is that the annular gasket 116 can be pressed more tightly by the first deformation block 102, the second deformation block 103, the first side rail 101 and the second side rail 105, thereby achieving a better sealing effect.
Referring to fig. 1, 2 and 6, the first side rail 101 is provided with a first sealing strip 115, and the first sealing strip 115 and an outer edge 118 of the annular gasket 116 ensure a sealing effect at the junction of the first side rail 101 and the annular gasket 116. Similarly, the second side beam 105 is provided with a second sealing strip 116, the second sealing strip 116 is simultaneously abutted with the first sealing strip 115 and the outer edge 118 of the annular sealing pad 116, and the abutment of the first side beam 101 and the second side beam 105 can enable the joint of the first side beam and the second side beam to be continuously sealed.
The present embodiment also provides a battery pack including: as with the battery tray 100 described above, batteries (not shown). The battery is accommodated in the battery accommodating space 113 of the battery tray 100.
The present embodiment also provides an automobile mounted with the battery tray 100 or the battery pack as described above.
The foregoing embodiments mainly describe differences between the embodiments, and as long as there is no contradiction between different optimization features of the embodiments, the embodiments may be combined to form a better embodiment, and in consideration of brevity of line text, no further description is given here.

It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present application.
