[0010] As a further preferred embodiment, the trigger portion is bent toward the center of the lamp holder, so that the first terminal enters the lamp holder and is plugged into the lamp holder at the center of the lamp holder to power on the searchlight.

[0011] As a further preferred embodiment, a bending piece is provided on the inner surface of the baffle, the bending piece is close to the lamp socket, and the bending piece is bent toward the direction of the photovoltaic panel.

[0012] As a further preferred embodiment, a movable groove is provided on the bending member, and the movable groove corresponds to the bottom side of the trigger rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When the impact force from the front directly acts on the searchlight, the searchlight will retreat, and the second spring will be compressed and shortened, thus providing buffer protection for the searchlight. In addition, the lamp holder will move backward with the terminal, so that the terminal connected to the searchlight will automatically cut off the power. When the above-mentioned impact accident occurs suddenly, the searchlight will automatically cut off the power supply, thus further improving the protection of the searchlight; and when the impact force from the front directly acts on the photovoltaic panel, the first spring will be compressed and shortened, providing a buffer effect for the connecting frame, and transmitting the buffer effect to the photovoltaic panel, thus providing buffer protection for the photovoltaic panel. In addition, the trigger part moves in the same direction with the first terminal, so that the output end of the first terminal is separated from the terminal on the lamp holder, and the input end of the first terminal is separated from the second terminal on the terminal holder. Since the current on the second terminal comes from the photovoltaic panel, the second terminal is the current source. At this time, when the input end of the first terminal is separated from the second terminal on the terminal holder, it is equivalent to cutting off the power supply to the first terminal, which is equivalent to automatically cutting off the power supply to the searchlight, which is equivalent to automatically cutting off the power supply when the searchlight or the photovoltaic panel is damaged by external force, so as to avoid circuit overload and fire in the event of an accident.

[0015] 2. A corrugated rubber seat is arranged in the protection space, and the corrugated rubber seat is filled with an expansion agent containing a flame retardant. When the trigger rod moves toward one side of the baffle, the corrugated rubber seat is squeezed, and the corrugated rubber seat compresses the buffer and produces a buffer effect. The buffer effect produced by the corrugated rubber seat assists the first spring in buffering and protecting the photovoltaic panel, and the buffer effect produced by the corrugated rubber seat also assists the second spring in buffering and protecting the searchlight. If high heat is caused by overload of the photovoltaic panel or failure of the searchlight, the heat is collected in the protection space. As the failure time becomes longer, the heat will rise sharply in the protection space. The high heat is transferred to the corrugated rubber seat through the protection space, or transferred to the corrugated rubber seat by the trigger rod and the bending part, so that the corrugated rubber seat expands, and at the same time, the expansion agent in the corrugated rubber seat releases the expansion effect, so that the expansion degree of the corrugated rubber seat increases. As the heat rises, the corrugated rubber seat will crack, and the internal expansion agent will be sprayed into the protection space, and part of the expansion agent will be sprayed into the space below along the movable groove for flame retardancy.

DETAILED DESCRIPTION

[0026] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0027] In one embodiment, Figure 1-Figure 9 As shown:

[0028] This embodiment provides a light electric bicycle with an external energy supply function, including a front frame 1, a photovoltaic module 2 arranged on the front frame 1, and a protection mechanism 3 arranged on the photovoltaic module 2 and the front frame 1;

[0029] An inclined surface 4 is provided on the upper front side of the front frame 1 of the vehicle body, and an assembly opening 5 is opened on the upper front side of the front frame 1 of the vehicle body according to the inclined surface 4. A rounded corner 28 is provided on the periphery of the front frame 1 of the vehicle body. The photovoltaic assembly 2 includes a photovoltaic panel 6 arranged in the assembly opening 5, a connecting frame 7 arranged on the inner surface of the photovoltaic panel 6, and a trigger rod 8 arranged on the inner surface of the photovoltaic panel 6. A baffle 9 is fixed to the rear side of the front frame 1, and a protective space 10 is formed between the baffle 9 and the photovoltaic panel 6. The protective mechanism 3 includes a fixing sleeve 11 fixed on the inner surface of the baffle 9 and a first spring 12 sleeved on the fixing sleeve 11. The other end of the fixing sleeve 11 extends toward the photovoltaic panel 6 in the protective space 10 and is installed with a nut 13 through an external thread. The connecting frame 7 is a U-shaped bending part, and one end of the U-shaped connecting frame 7 extends in the protective space 10 and opens A sleeve hole 14 is sleeved on the fixing sleeve 11, and one end with the sleeve hole 14 is limited between the first spring 12 and the nut 13. An assembly groove 15 is provided on the front frame 1 of the vehicle body, and a lamp socket 16 is opened in the assembly groove 15. A lamp holder 17 is provided on the lamp holder 16, and a lamp slot 18 is provided in the lamp holder 17. A quick-release port 19 communicating with the lamp slot 18 is provided on the front side of the lamp holder 17. The protection mechanism 3 also includes a second spring 20 filled in the lamp slot 18. The lamp holder 17 is equipped with a searchlight 21 through the quick-release port 19. The lamp holder seat 22 is supported on the second spring 20. The free end of the trigger rod 8 is provided with a trigger part 23 entering into the lamp holder seat 22. A terminal seat 24 is provided on the inner side of the inclined surface 4. The protection mechanism 3 also includes a power-off component 25, and the photovoltaic integrated module is installed on the inner surface of the inclined surface 4.

[0030] The power-off component 25 includes a first terminal 26 arranged on the trigger part 23 and a second terminal 27 arranged on the photovoltaic integrated module. The current output end of the second terminal 27 is connected to the current input end of the first terminal 26 through a USB cable, and the current output end of the first terminal 26 is connected to the lamp holder 22.

[0031] like Figure 1 , Figure 2 as well as Figure 5As shown, the assembly groove 15 is located below the inclined surface 4, the assembly groove 15 is a long groove, and there are two lamp holders 16, which are symmetrically opened at the left and right ends of the assembly groove 15. A lamp holder 17 of the same structure is installed on each of the two lamp holders 16, and a searchlight 21 is installed on each of the two lamp holders 16 in the same installation manner. The installation method of the searchlight 21 is different from that of the prior art. During installation, align the two pins on the lamp holder 22 with the two quick-loading ports 19 so that the two pins are inserted into the two quick-loading ports 19, and at the same time, the two pins enter the lamp slot 18 and are stuck in the lamp slot 18. Then rotate the searchlight 21, and the lamp holder 22 is rotated with the searchlight 21, and the lamp holder 22 is rotated with the two pins so that the pins are misaligned with the lamp slot 18. At this time, the lamp holder 22 is fixed on the lamp holder 17, and the lamp holder 22 is fixed on the lamp holder 17 with the searchlight 21. The inner end of the lamp holder 22 is pressed against the second spring 20, so that the searchlight 21 has a buffering effect on the lamp holder 17. Finally, the output end of the first terminal 26 is connected to the terminal on the lamp holder 22.

[0032] like Figure 7 , Fig. 9 As shown, the trigger part 23 bends toward the center of the lamp holder 22, so that the first terminal 26 enters the lamp holder 22 and is plugged into the lamp holder 22 at the center of the lamp holder 22, so that the searchlight 21 is powered. When the trigger part 23 moves toward one side of the baffle 9 under the drive of the trigger rod 8, the first terminal 26 is separated from the terminal on the lamp holder 22, and the searchlight 21 is automatically powered off.

[0033] A bending piece 29 is provided on the inner surface of the baffle 9, and the bending piece 29 is close to the lamp socket 16. The bending piece 29 is bent toward the direction of the photovoltaic panel 6. The protection mechanism 3 also includes a corrugated rubber seat 31 installed on the bending piece 29. The corrugated rubber seat 31 is filled with an expansion material. The corrugated rubber seat 31 is located on the inner side of the photovoltaic panel 6. The other end of the corrugated rubber seat 31 is pushed upward on the bottom surface of the trigger rod 8. The expansion material is a mixture of an expansion agent and a flame retardant.

[0034] The bending piece 29 is provided with a movable groove 30 , which corresponds to the bottom side of the trigger rod 8 .

[0035] Working principle and effect: When the impact force from the front directly acts on the searchlight 21, the searchlight 21 will retreat backwards. At this time, the searchlight 21 will move backwards with the lamp holder 22. The lamp holder 22 pushes the second spring 20 to compress and shorten. The second spring 20 generates a buffer force to form a buffer protection for the searchlight 21. In addition, the lamp holder 22 will move backwards with the terminal, and the terminal will push the trigger part 23. The trigger part 23 drives the trigger rod 8 to move toward one side of the baffle 9 in the protection space 10, and the trigger part 23 drives the first terminal 26 to move in the same direction. The first terminal 26 is moved to separate the output end of the first terminal 26 from the terminal on the lamp holder 22, and the input end of the first terminal 26 is separated from the second terminal 27 on the terminal holder 24. In addition, the trigger rod 8 will lead the photovoltaic panel 6 to move along the protection space 10 toward one side of the baffle 9, and the photovoltaic panel 6 will lead the connecting frame 7 to slide downward along the fixing sleeve 11. At this time, the connecting frame 7 squeezes the first spring 12, and the first spring 12 compresses the buffer, which amplifies the above buffer effect and further improves the protection of the searchlight 21. When the impact force from the front directly acts on the photovoltaic panel 6 When the photovoltaic panel 6 is raised, the photovoltaic panel 6 is used as the initial power to drive the connecting frame 7 to slide downward along the fixing sleeve 11, and the first spring 12 is compressed and shortened by the connecting frame 7, and the first spring 12 provides a buffering effect to the connecting frame 7, and the buffering effect is transmitted to the photovoltaic panel 6, so that the photovoltaic panel 6 is buffered and protected. In addition, the photovoltaic panel 6 will also bring the trigger rod 8 to move toward one side of the baffle 9 in the protection space 10, and the trigger rod 8 will bring the trigger part 23 to move toward one side of the baffle 9, and the trigger part 23 will bring the first terminal 26 to move in the same direction, so that the first terminal 26 The output end is separated from the terminal on the lamp holder 22, so that the input end of the first terminal 26 is separated from the second terminal 27 on the terminal holder 24. The current on the second terminal 27 comes from the photovoltaic panel 6, so the second terminal 27 is the current source. At this time, when the input end of the first terminal 26 is separated from the second terminal 27 on the terminal holder 24, it is equivalent to cutting off the power supply of the first terminal 26, which is equivalent to automatically cutting off the power supply of the searchlight 21, which is equivalent to automatically cutting off the power supply when the searchlight 21 or the photovoltaic panel 6 is damaged by external force, so as to avoid circuit overload and fire in the event of an accident.

[0036] In another embodiment, when the trigger rod 8 moves toward one side of the baffle 9, it will also squeeze the corrugated rubber seat 31. The corrugated rubber seat 31 compresses the buffer and produces a buffering effect. The buffering effect produced by the corrugated rubber seat 31 assists the first spring 12 in buffering and protecting the photovoltaic panel 6. The buffering effect produced by the corrugated rubber seat 31 also assists the second spring 20 in buffering and protecting the searchlight 21. If high heat is caused by overload of the photovoltaic panel 6 or failure of the searchlight 21, the heat will be collected in the protection space 10. As the failure time becomes longer, the heat will rise sharply in the protection space 10. The high heat is transferred to the corrugated rubber seat 31 through the protection space 10, or is transferred to the corrugated rubber seat 31 by the trigger rod 8 and the bending part 29, so that the corrugated rubber seat 31 expands, and at the same time, the expansion agent in the corrugated rubber seat 31 releases the expansion effect, so that the expansion degree of the corrugated rubber seat 31 becomes larger. As the heat rises, the corrugated rubber seat 31 will crack, and the internal expansion agent will be sprayed into the protection space 10, and part of the expansion agent will be sprayed into the space below along the movable groove 30 to be flame retardant.

[0037] It should be further explained that the socket of the second terminal 27 is tilted downward. When the input end of the first terminal 26 is connected to the second terminal 27 through the socket, the input end of the first terminal 26 will also tilt downward. Therefore, when the trigger part 23 moves with the first terminal 26 toward one side of the baffle 9, in addition to directly separating the output end of the first terminal 26 from the terminal on the lamp holder 22, the input end of the first terminal 26 will also be quickly separated from the socket of the second terminal 27, so that the searchlight 21 is effectively powered off.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field.
