In addition, when the two battery holders 10 are connected in series and then rotate relatively, the batteries 15 in the two battery holders 10 may not be electrically connected. By providing the corresponding positioning grooves 1113 and ribs 1313 on the first fixing unit 11 and the second fixing unit 13, the above-mentioned situation can be avoided, which is beneficial to improving the convenience of assembly and the reliability of use.
In an embodiment of the present invention, a first through hole 1115 is disposed on the recess 111 and/or the groove 1111 of the first fixing unit 11, wherein the first through hole 1115 penetrates through the outer surface 112 and the inner surface 114 of the first fixing unit 11, and a second through hole 1315 is disposed on the protrusion 131 and/or the body portion 1311 of the second fixing unit 13, wherein the second through hole 1315 penetrates through the outer surface 132 and the inner surface 134 of the second fixing unit 13.
Referring to fig. 2 again, in the present embodiment, the fixing mechanism 1 further includes two front rods 171 and two rear rods 172 with male threads and a nut 173, wherein the two front rods 171 and the rear rods 172 with male threads are respectively provided with a tail-end male thread portion 1711 and a top-end male thread portion 1712 at one end thereof. An internal threaded portion (not shown) is provided in the nut 173. The nut 173 has a polygonal or circular three-dimensional cross section.
Each set of battery holders 10 can be assembled in series by fastening two front rods 171 and rear rods 172 with male threads and nuts 173 to form a multi-cell battery module. That is, after the series connection assembly, each set of battery holder 10 will become each section of the multi-section battery module. In the embodiment of fig. 2, the position of the nut 173 is selected between the sections of the multi-section battery module, for example: the nut 173 is disposed between one of the battery holders 10 and the other adjacent battery holder 10 and aligned to the first through hole 1115 of the first fixing unit 11 of one of the battery holders 10 and aligned to the second through hole 1315 of the second fixing unit 13 of the other adjacent battery holder 10. In an embodiment of the present invention, the lengths of the front rod 171 and the rear rod 172 may be designed to be equal; alternatively, in another embodiment of the present invention, the lengths of the front rod 171 and the rear rod 172 may be designed to be different.
When the battery holders 10 are to be assembled in series, the protrusion 131 of the second fixing unit 13 of each battery holder 10 is inserted into the recess 111 of the first fixing unit 11 of another battery holder 10, then the front rod 171 and the rear rod 172 respectively pass through the corresponding first through hole 1315 of the first fixing unit 11 and the second through hole 1315 of the second fixing unit 1115 of the battery holder 10, and the external screw thread 1711 at the tail end and the external screw thread 1712 at the top end of the front rod 171 and the rear rod 172 respectively screw with the internal screw thread of the nut 173 to be locked together, so as to fix each battery holder 10.
Furthermore, the battery holder 10 and the nut 173 of the present invention are assembled by insert injection, thermal melting, ultrasonic embedding, and direct assembly.
In addition, when the inner surface 114 of the first fixing unit 11 is provided with the first extending portion 117 and the inner surface 134 of the second fixing unit 13 is provided with the second extending portion 137, the first through hole 1115 of the first fixing unit 11 can extend from the recess 111 and/or the groove 1111 to the first extending portion 117, as shown in fig. 3 and 4; the second through hole 1315 of the second fixing unit 13 extends from the protruding portion 131 and/or the main portion 1311 to the second extending portion 137, as shown in fig. 5 and 6.
In addition, the recess 111 having the groove 1111 and the positioning groove 113 and the protrusion 131 having the body 1311 and the rib 1313 are only one embodiment of the utility model, and are not limited by the scope of the utility model. In practical applications, the protrusion 131 of the battery holder 10 can limit the connection angle between two adjacent or connected battery holders 10 after being inserted into the recess 111 of the adjacent battery holder 10.
Fig. 7 is an exploded perspective view of a fixing mechanism for a multi-cell battery module according to another embodiment of the present invention. Compared to the embodiment of fig. 2, the nut 173 is selectively disposed between the sections of the multi-section battery module, and in the embodiment of fig. 7, the nut 173 is selectively disposed in the same section, for example: the nut 173 is disposed between the first fixing unit 11 and the second fixing unit 13 of the battery holder 10 of the same section, and aligned with the first through hole 1115 of the first fixing unit 11 and the second through hole 1315 of the second fixing unit 13. Thus, when the front rod 171 and the rear rod 172 respectively pass through the corresponding first through hole 1115 of the first fixing unit 11 and the corresponding second through hole 1315 of the second fixing unit 13, the front rod can be screwed and fastened with the nut 173 disposed in a specific battery holder 10, so as to fix each battery holder 10 of the multi-battery module.
Fig. 8 is an exploded perspective view of a fixing mechanism for a multi-cell module according to another embodiment of the present invention. In contrast to the above-mentioned embodiment, the front rod 171 and the rear rod 172 are locked with a nut 173 to fix the multi-cell battery modules, and in the embodiment of fig. 8, a first rod 181 with male threads and a second rod 183 with female threads are locked to fix the multi-cell battery modules. The first rod 181 has an external thread portion 1811 at one end thereof, and the second rod 183 has an internal thread portion 1831 at one end thereof. When the first rod 181 and the second rod 183 respectively pass through the corresponding first through hole 1115 of the first fixing unit 11 and the corresponding second through hole 1315 of the second fixing unit 13, the external thread portion 1811 and the internal thread portion 1831 can be screwed together to fix each battery holder 10 of the multi-cell battery module. Furthermore, the lengths of the first rod 181 and the second rod 183 of the present embodiment can be designed to be equal or unequal.
Fig. 9 is a schematic cross-sectional view of a concave portion and a convex portion of a first fixing unit according to an embodiment of the utility model. The present invention mainly provides a concave portion 111 on the first fixing unit 11 and a convex portion 131 on the second fixing unit 13 to limit the connection angle between the first fixing unit 11 and the second fixing unit 13. Specifically, the first fixing unit 11 and the second fixing unit 13 can insert the protrusion 131 of the second fixing unit 13 into the recess 111 of the first fixing unit 11 only at a specific angle. In addition, when the protrusion 131 of the second fixing unit 13 is inserted into the recess 111 of the first fixing unit 11, the second fixing unit 13 and the first fixing unit 11 will not rotate relatively.
The cross-section of the concave portion 111 of the first fixing unit 11 and the convex portion 131 of the second fixing unit 13 may be a non-centrosymmetric pattern with similar shapes, so as to achieve the above-mentioned purpose. Specifically, the cross-sectional geometrical shapes of the concave portion 111 of the first fixing unit 11 and the convex portion 131 of the second fixing unit 13 are as shown in fig. 9, for example, the cross-section of the groove 1111 and/or the main body portion 1311 may be a polygon such as a circle, a triangle, a quadrangle, a pentagon or a hexagon, and one or more positioning grooves 1113 and ribs 1313 are connected.
In practice, the recess 111 and the protrusion 131 only need to have the effect of preventing the first fixing unit 11 and the second fixing unit 13 from rotating relative to each other, and the positioning groove 1113 and the rib 1313 are not required. For example, the cross sections of the concave portion 111 and the convex portion 131 may be isosceles triangles, trapezoids, etc. other than regular triangles, so as to achieve the purpose of fool-proofing and preventing the first fixing unit 11 and the second fixing unit 13 from rotating relatively.
In summary, when the demand of battery capacity increases and the overall length of the battery becomes longer and longer, the length of the rod body reaches the limit, and the design cannot be met, the fixing mechanism of the multi-section battery module of the present invention mainly combines the front rod body 171 and the rear rod body 172 together by matching nuts, and the lengths of the front rod body 171 and the rear rod body 172 can be designed to be equal or unequal in length and can be movably assembled with or disassembled from the battery fixing frame, so as to solve the conventional limitation of the fixed length of the ultra-long rod body.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the utility model, which is defined by the appended claims.
