[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] refer to Figure 1-3 As shown, the utility model provides a dual-group LED driving power supply, including: a shell 5 with an input line 1 and an output line 6 connected at both ends, a storage bin 3 is opened on the shell 5, two driving power supply bodies 4 are arranged side by side in the storage bin 3, and a buckle plate 2 is provided on the outer side of the two driving power supply bodies 4, and the two ends of the buckle plate 2 are respectively clamped on the symmetrical two sides of the shell 5.

[0023] As mentioned above, when using the output line 6, input line 1, shell 5 and buckle plate 2 provided by the utility model, the two driving power supply bodies 4 are placed into the storage bin 3 in turn. During this process, the two ends of the two driving power supply bodies 4 are respectively connected to the output line 6 and the input line 1, and then the buckle plate 2 is buckled on the outside of the storage bin 3. At this time, the buckle plate 2 is used to prevent the driving power supply body 4 from escaping from the storage bin 3.

[0024] Further, in order to detachably mount the gusset plate 2 on the housing 5, refer to Figure 3 As shown, the gusset plate 2 is a U-shaped structure, and blocks 9 are protruding from the inner sides of both ends of the gusset plate 2. Card slots 10 are provided on both symmetrical sides of the shell 5, and the two card slots 10 are respectively connected to the corresponding card slots 10. When the two driving power supply bodies 4 are placed in the storage bin 3, the gusset plate 2 is buckled on the outside of the storage bin 3. At this time, the card blocks 9 on the gusset plate 2 can be connected to the card slots 10 on both sides respectively to prevent the gusset plate 2 from being separated from the shell 5, thereby preventing the driving power supply body 4 from being separated from the shell 5. When the driving power supply body 4 needs to be replaced, the card block 9 is separated from the card slot 10, so that the gusset plate 2 is removed from the shell 5, and then the driving power supply body 4 can be taken out of the storage bin 3.

[0025] Further, in order to prevent the driving power source body 4 from being displaced in the storage bin 3, refer to Figure 1 and Figure 3 As described above, a partition 8 is installed in the storage bin 3, and the partition 8 is arranged between the two driving power source bodies 4. The partition 8 can separate the storage bin 3 into two storage spaces of the same size, and the two driving power source bodies 4 are stored in the two storage spaces respectively, so as to prevent the two driving power source bodies 4 from being displaced in the storage bin 3.

[0026] In the present utility model, combined with Figure 3 As shown, connection mechanisms electrically connected to the corresponding driving power source body 4 are installed on both sides of the storage bin 3 of this embodiment.

[0027] Combination Figure 4As shown, the connection mechanism includes two contact heads 7, and two mounting holes 12 are arranged in parallel at the end of the storage bin 3. Springs 14 connected to the corresponding contact heads 7 are installed in the two mounting holes 12, and one end of each of the two contact heads 7 at least partially extends into the corresponding mounting hole 12, and one end of the output line 6 and the input line 1 are electrically connected to the corresponding contact heads 7 respectively;

[0028] Two electric contact pieces 11 are embedded at both ends of the driving power source body 4 , and one end of each contact head 7 abuts against the corresponding electric contact piece 11 .

[0029] As described above, when using the connection mechanism provided by the utility model, the contact head 7 in the connection mechanism is telescopically installed in the shell 5 through the mounting hole 12, and one end of the contact head 7 is located in the storage bin 3. The contact head 7 can be telescopically reciprocated in the mounting hole 12 by the elastic force of the spring 14. When the driving power source body 4 is installed in the storage bin 3, the contact head 7 is always in contact with the electric contact piece 11 by the elastic force of the spring 14, so that the contact head 7 always maintains an electrical connection with the electric contact piece 11.

[0030] Further, in order to connect the output line 6 and the input line 1 to the two driving power supply bodies 4 respectively, refer to Figure 4 As shown, the output line 6 and the input line 1 are both formed by twisting two battery cells 15, and a connecting line 13 is electrically connected between one end of each battery cell 15 and the corresponding two contact heads 7. The connecting line 13 allows the contact head 7 to be softly connected to the battery cell 15, and the contact head 7 will not be disconnected from the battery cell 15 during the process of extension and retraction. Each battery cell 15 can be positive or negative. The contact head 7 connected to the positive battery cell 15 is the positive electrode, and the contact head 7 connected to the negative battery cell 15 is the negative electrode. When the driving power supply body 4 is placed in the storage bin 3, the negative electrode electric contact sheet 11 on the driving power supply body 4 contacts the negative electrode contact head 7, and the positive electrode electric contact sheet 11 on the driving power supply body 4 contacts the positive electrode contact head 7.
