[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other alternative implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0054] This application provides a multifunctional bicycle taillight device 10, which is installed on a bicycle and can realize functions such as braking, steering, dynamic display, and interactive team display, enriching the display modes of the multifunctional bicycle taillight device 10 and improving the user experience. The bicycle can be a road bike, mountain bike, city bike, folding bike, touring bike, etc.
[0055] like Figures 1A to 12D As shown, in one embodiment of the multifunctional bicycle taillight device 10, in Figures 8A to 9 The multifunctional bicycle tail-end light-emitting device 10 includes a housing 200, an optical module 100, and a light source assembly 300. The housing 200 has an accommodating space 201, and the head of the housing 200 has a lateral opening 202 communicating with the accommodating space 201. The optical module 100 is disposed in the accommodating space 201. The head of the optical module 100 has a comb-shaped light-emitting area 160, and at least the comb-shaped light-emitting area 160 is exposed through the lateral opening 202. The tail of the optical module 100 has a plurality of lamp-holding cavities 121 opposite to the comb-shaped light-emitting area 160. The light source assembly 300 is disposed in the accommodating space 201 and located on one side of the tail of the optical module 100. The light source assembly 300 includes a lamp plate 310 and a plurality of lamp beads 320 disposed on the lamp plate 310, each lamp bead 320 being housed in a corresponding lamp-holding cavity 121.
[0056] In this embodiment, the light source assembly 300 has multiple LED beads 320, and the distribution of the LED beads 320 on the lamp plate 310 corresponds to the comb-shaped light-emitting area 160 at the head of the optical module 100. After the LED beads 320 on the light source assembly 300 are powered on and emit light, the light is introduced into the optical module 100 from the tail and emitted from the comb-shaped light-emitting area 160 at the head of the optical module 100. By controlling the multiple LED beads 320 at the tail of the optical module 100 to emit light or not emit light, the comb-shaped light-emitting area 160 can be partially or completely illuminated, thereby forming a variety of different patterns, dynamic or static display effects in the comb-shaped light-emitting area 160, so that the multifunctional bicycle tail light-emitting device 10 can reflect the bicycle's riding status through these display effects.
[0057] It should be noted that the optical module 100 in this application has various types. The following describes various embodiments of the optical module 100 in the multifunctional bicycle taillight device 10:
[0058] like Figures 1A to 1H As shown, in this embodiment, the comb-shaped light-emitting area 160 includes a horizontal light-emitting area 111 and a plurality of vertical light-emitting areas 131. Both the horizontal light-emitting area 111 and the vertical light-emitting areas 131 are generally elongated strip shapes. The plurality of vertical light-emitting areas 131 are located below the horizontal light-emitting area 111, and there is a gap between two adjacent vertical light-emitting areas 131. The horizontal light-emitting area 111 and each vertical light-emitting area 131 can emit light individually or emit light in concert with each other, thereby forming a variety of different patterns, dynamic or static display effects.
[0059] Furthermore, the optical module 100 has a comb-like structure, including a transverse light guide 110 and multiple longitudinal light guides 130. The transverse light-emitting region 111 is located at the head of the transverse light guide 110, and the tail of the transverse light guide 110 has at least one light source input section 120. The multiple longitudinal light guides 130 are spaced apart along the transverse direction of the transverse light guide 110 on one side of the transverse light guide 110. Specifically, in… Figure 1A In this structure, multiple longitudinal light guides 130 are distributed on one side of the bottom surface of the transverse light guide 110; and preferably, all of the multiple longitudinal light guides 130 are perpendicular to the transverse light guide 110. The longitudinal light-emitting area 131 is located at least at the head of the longitudinal light guide 130, and each longitudinal light guide 130 has at least one light source input section 120 at its tail; at the same time, each light source input section 120 has a lamp cavity 121, so that the lamp beads 320 (e.g., LED lamp beads) on the light source assembly 300 can be housed in the lamp cavity 121, and after the lamp beads 320 are powered on and emit light, they input light to the corresponding transverse light guide 110 or longitudinal light guide 130.
[0060] In this embodiment, both the transverse light guide 110 and the longitudinal light guide 130 are optical elements capable of allowing light to propagate. After the light emitted by the LED bead 320 at the tail of the transverse light guide 110 is refracted inside the transverse light guide 110, it is emitted from the transverse light emission area 111. After the light emitted by the LED bead 320 at the tail of the longitudinal light guide 130 is refracted inside the longitudinal light guide 130, it is emitted from the longitudinal light emission area 131.
[0061] In this application, the number of longitudinal light guides 130 is 3 to 8. For example, in Figures 1A to 1H as well as Figures 2 to 4 , Figures 7B to 7F In the embodiments shown, the number of longitudinal light guides 130 is four; Figure 5A and Figure 5B and Figure 7AIn the embodiments shown, the number of longitudinal light guides 130 is three; Figure 6A and Figure 6B In the embodiments shown, there are 5 longitudinal light guides 130.
[0062] like Figures 1E to 1H As shown, in this embodiment, there are four vertical light guides 130, and correspondingly, each vertical light guide 130 has four vertical light emitting regions 131, which are respectively defined as the first vertical light emitting region 1301, the second vertical light emitting region 1302, the third vertical light emitting region 1303, and the fourth vertical light emitting region 1304. This application uses this embodiment as an example to illustrate that the horizontal light emitting region 111 and the multiple vertical light emitting regions 131 can form various different patterns, dynamic or static display effects.
[0063] The optical module 100 in this embodiment can display the "braking status". Figure 1E In the diagram, the horizontal light-emitting area 111, the second vertical light-emitting area 1302, and the third vertical light-emitting area 1303 emit light, and the black pattern is used to indicate that they are in the display state. After the horizontal light-emitting area 111, the second vertical light-emitting area 1302, and the third vertical light-emitting area 1303 emit light, they form a "π" shaped pattern, which represents the "braking state". In actual use, the LED bead 320 is an RGB light source that can emit light of multiple colors. Preferably, the "π" shaped pattern is displayed with red light.
[0064] In some other embodiments, for example Figure 5A and Figure 5B In the illustrated embodiment, when there are three longitudinal light guides 130, that is, three longitudinal light-emitting regions 131, they are respectively defined as the first longitudinal light-emitting region, the second longitudinal light-emitting region, and the third longitudinal light-emitting region. After the lateral light-emitting region and the second longitudinal light-emitting region emit light, they present a "T"-shaped pattern, which represents the "braking state". In some other embodiments, when there are more than four longitudinal light guides 130, a "π"-shaped pattern or other custom patterns can also be used to represent the "braking state".
[0065] Furthermore, the optical module 100 in this embodiment can display a "double flash status". Figure 1F In the first longitudinal light-emitting area 1301 and the fourth longitudinal light-emitting area 1304 emit light and flash, indicating a "double-flash state". Preferably, in the "double-flash state", the light emitted by the LED 320 is yellow light. In some other embodiments, when the number of longitudinal light guides 130 is 3 or more, it is preferable that the "double-flash state" is indicated by the light emitting and flashing of the two longitudinal light-emitting areas 131 on both sides of the edge of the transverse light guide 110.
[0066] Furthermore, the optical module 100 in this embodiment can display "left turn status" and "right turn status". Figure 1G In the middle, the first longitudinal light-emitting region 1301 to the fourth longitudinal light-emitting region 1304 emit light sequentially to indicate the "right-turning state"; similarly, in Figure 1H In this configuration, light is emitted sequentially from the fourth longitudinal light-emitting area 1304 to the first longitudinal light-emitting area 1301, thereby indicating a "left turn state." This method enables auxiliary steering, providing guidance for bicycle turning. In other embodiments, when the number of longitudinal light guides 130 is three or more, the "left turn state" or "right turn state" can also be indicated by referring to the above display method, which will not be elaborated here.
[0067] Furthermore, the optical module 100 in this embodiment can display a "dynamic display effect." The horizontal light-emitting area 111 and the multiple vertical light-emitting areas 131, in conjunction with the various colors of light emitted by the LED beads 320, can achieve a dynamic display effect. For example, the horizontal light-emitting area 111 and the multiple vertical light-emitting areas 131 can flash, flow, or gradually change at a fixed frequency; the multiple vertical light-emitting areas 131 can flash alternately; the light from the multiple vertical light-emitting areas 131 can flow from left to right or from right to left, simulating dynamic effects, etc.
[0068] Furthermore, when the optical module 100 is integrated into the multi-functional bicycle taillight device 10, it can also enable team formation. For example, each rider's bicycle in a cycling team is equipped with a multi-functional bicycle taillight device 10. When one of the multi-functional bicycle taillight devices 10 randomly displays a dynamic color combination through the optical module 100, the other multi-functional bicycle taillight devices 10 receive a team formation invitation (the multi-functional bicycle taillight devices 10 can communicate wirelessly via Bluetooth) and respond, displaying the same dynamic color combination. In this way, each multi-functional bicycle taillight device 10 in the cycling team has the same light display effect, indicating that they belong to the same team. In addition, during the ride, the same light display effect can also help identify members of the same team.
[0069] Furthermore, such as Figures 1A to 1D As shown, the transverse light guide 110 has a transversely arranged plate-like structure with a flat bottom surface and an arched top surface. The surface of the head of the transverse light guide 110 is used as the transverse light emission area 111. In this embodiment, the surface of the head of the transverse light guide 110 is an arc surface. In the transverse direction of the transverse light guide 110, the surface of the head of the transverse light guide 110 is high in the middle and low at both ends.
[0070] In some embodiments, the surface of the head of the transverse light guide 110 may also be planar. In other embodiments, the top surface of the transverse light guide 110 may also be planar; in some embodiments, in order to expand the display area of the transverse light emission region 111, the surface of the head of the transverse light guide 110 includes multiple sub-surfaces, for example... Figure 3A and Figure 3B In the illustrated embodiment, the surface of the head of the transverse light guide 110 includes a first sub-surface 1101, a second sub-surface 1102, a third sub-surface 1103, and a fourth sub-surface 1104. The first sub-surface 1101 and the second sub-surface 1102 are located in the middle region of the head of the transverse light guide 110, and the first sub-surface 1101 is located in front of the second sub-surface 1102. The third sub-surface 1103 and the fourth sub-surface 1104 are located on both sides of the head of the transverse light guide 110.
[0071] Furthermore, such as Figure 1C As shown, in some embodiments, in order to enhance the display effect of the horizontal light-emitting area 111, a plurality of light-emitting protrusions 150 with arc surfaces are distributed in the horizontal light-emitting area 111, thereby increasing the light-emitting area of the horizontal light-emitting area 111 and improving the display effect; at the same time, these light-emitting protrusions 150 also serve as an appearance decoration effect.
[0072] Furthermore, the longitudinal light guides 130 have a vertically arranged plate-like structure, and there are gaps between the multiple longitudinal light guides 130. For example... Figure 1A and Figure 1D As shown, the circumferential contour of the longitudinal light guide 130 has a first longitudinal arc-shaped edge 132 in the form of a line. The first longitudinal arc-shaped edge 132 is in the shape of an arc blade and serves as the longitudinal light-emitting region 131. The starting end of the first longitudinal arc-shaped edge 132 is located at the head of the longitudinal light guide 130 and is adjacent to the transverse light guide 110. The ending end of the first longitudinal arc-shaped edge 132 extends towards the tail of the longitudinal light guide 130 and gradually moves away from the transverse light guide 110.
[0073] like Figure 7A As shown, in some embodiments, the longitudinal light guide 130 is a plate-like structure with a rectangular cross-section, and the surface of the head of the longitudinal light guide 130 is a plane, which serves as the longitudinal light output area 131.
[0074] Furthermore, such as Figure 3A and Figure 3BAs shown, in some embodiments, in the two longitudinal light guides 130 distributed on both sides of the edge of the transverse light guide 110, the outer sides of the first longitudinal arc-shaped edges 132 of the two longitudinal light guides 130 are partially chamfered, so that the longitudinal light-emitting area 131 is divided into a first longitudinal sub-light-emitting area 1311 and a second longitudinal sub-light-emitting area 1312; the second longitudinal sub-light-emitting area 1312 is inclined relative to the first longitudinal sub-light-emitting area 1311, thereby enhancing the light-emitting area of the longitudinal light guide 130 and enabling it to be displayed laterally.
[0075] In some other alternative embodiments, the above Figure 3A and Figure 3B The outer side of the first longitudinal arc-shaped edge 132 of the two longitudinal light guides 130 can be replaced by "doing chamfer treatment" with "doing rounded corner treatment".
[0076] like Figure 4 As shown, in some other embodiments, the first longitudinal arc-shaped edges 132 of the two longitudinal light guides 130 distributed on both sides of the edge of the transverse light guide 110 are all rounded, thereby enhancing the light-emitting area of the longitudinal light guide 130 and enabling it to be displayed from the side.
[0077] Furthermore, in order to enhance the display effect of the vertical light-emitting area 131, at least one of the vertical light-emitting areas 131 has a plurality of light-emitting protrusions 150 with curved surfaces distributed within it; thereby increasing the light-emitting area of the vertical light-emitting area 131 and improving the display effect; at the same time, these light-emitting protrusions 150 also serve as an aesthetic decoration effect.
[0078] like Figures 1A to 1H As shown, in one embodiment, each longitudinal light-emitting region 131 has light-emitting protrusions 150 with arc-shaped surfaces distributed within it; Figures 3A to 4 In the illustrated embodiment, only the two middle longitudinal light-emitting regions 131 have light-emitting protrusions 150 with curved surfaces. In other embodiments, whether each longitudinal light-emitting region 131 has light-emitting protrusions 150 can be adjusted according to display needs; various distribution methods will not be listed here.
[0079] Furthermore, such as Figures 7B to 7D As shown, in some embodiments, the optical module 100 further includes a head extension 191 and a lateral extension 192. The head extension 191 is disposed at the head of the transverse light guide 110 and extends in a direction away from the longitudinal light guide 130. Preferably, the head extension 191 is integrated with the head of the transverse light guide 110.
[0080] The lateral extension portion 192 has two parts, which are respectively disposed on the outer side of the two longitudinal light guides 130 distributed on both sides of the edge of the transverse light guide 110, that is, the lateral extension portion 192 extends towards the outer side of the longitudinal light guide 130; preferably, the lateral extension portion 192 is integrated with the two longitudinal light guides 130 on both sides of the edge of the transverse light guide 110.
[0081] In this embodiment, the optical module 100 is provided with a head extension 191 and a lateral extension 192, making the edge contour of the head of the optical module 100 larger than in other embodiments. This is to enable the optical module 100 to be organically integrated with the housing 200 of the multi-functional bicycle tail light-emitting device 10, achieving a smooth transition between the optical module 100 and the housing 200, and improving the aesthetics of the multi-functional bicycle tail light-emitting device 10.
[0082] like Figures 7E to 7F As shown, in some embodiments, the optical module 100 also has multiple light guide fins 170. Some of the light guide fins 170 are disposed on the side of the transverse light guide 110 away from the longitudinal light guide 130 and adjacent to the head of the transverse light guide 110; some of the light guide fins 170 are disposed on the outer sides of the two longitudinal light guides 130 distributed on both sides of the edge of the transverse light guide 110. The light guide fins 170 have a sheet-like structure, which can enhance the light-emitting area, allowing light to be emitted from the light guide fins 170 after passing through them; on the other hand, the light guide fins 170 can also serve a decorative purpose.
[0083] Furthermore, such as Figure 1B As shown, in this embodiment, the light source input section 120 has a cylindrical structure, and its cross-sectional dimensions gradually decrease in the direction away from the tail end of the longitudinal light guide 130; and as... Figure 1D As shown, when viewed from the side, the light source input section 120 is arched; the light source input section 120 also has a lamp housing cavity 121, which is disposed at the center of the light source input section 120 along the length direction of the light source input section 120, and the lamp housing cavity 121 is used to accommodate the lamp beads 320.
[0084] Furthermore, the rear end of the transverse light guide 110 is provided with at least two light source input sections 120; for example... Figures 1A to 6B The embodiment shown; in other embodiments, as the width of the transverse light guide 110 increases, more light source input sections 120 can be provided, such as 3, 4, etc.
[0085] Furthermore, the tail portions of the two longitudinal light guides 130 distributed on both sides of the edge of the transverse light guide 110 are respectively provided with two light source input sections 120, thereby enhancing the display effect of the longitudinal light-emitting area 131; the tail portions of the two longitudinal light guides 130 distributed in the middle of the edge of the transverse light guide 110 are respectively provided with one light source input section 120; in some other embodiments, the tail portion of each longitudinal light guide 130 may be provided with two light source input sections 120, and as the vertical height of the longitudinal light guide 130 increases, more light source input sections 120 may be provided, such as 3, 4, etc.
[0086] like Figure 1B As shown, the tail of the transverse light guide 110 is further provided with a first positioning part 140, which is preferably disposed on both sides of the tail of the transverse light guide 110; and at least a portion of the tails of the longitudinal light guides 130 are provided with the first positioning part 140, for example, the tails of the two longitudinal light guides 130 located at the middle of the edge of the transverse light guide 110 are each provided with a first positioning part 140; the first positioning part 140 has a columnar structure, which facilitates the positioning and installation of the optical module 100. Figures 7B to 7F As shown, in some other embodiments, the optical module 100 has a fixing slot 180 at its tail, and the optical module 100 is mounted to the multi-functional bicycle tail light-emitting device 10 through the fixing slot 180.
[0087] Furthermore, in this embodiment, multiple longitudinal light guides 130 and transverse light guides 110 are integrally formed, which facilitates processing and manufacturing.
[0088] Furthermore, in this embodiment, the optical module 100 is made of PC (polycarbonate) or PMMA (polymethyl methacrylate, acrylic), optical glass, etc.
[0089] The following describes the positioning component 400 and the light source assembly 300 in the multi-functional bicycle taillight device 10:
[0090] Combination Figures 8A to 10BThe positioning component 400 includes a positioning sleeve 410 and an isolation portion 420. The positioning sleeve 410 is located between the optical module 100 and the lamp plate 310 and is fitted onto the tail of the optical module 100. The side of the positioning sleeve 410 closest to the optical module 100 has a positioning cavity 411 adapted to the light source input portion 120. Multiple positioning cavities 411 are provided, each capable of accommodating at least one light source input portion 120, ensuring that each light source input portion 120 at the tail of the optical module 100 can be appropriately placed within its corresponding positioning cavity 411. Furthermore, each positioning cavity 411 has at least one lamp placement hole 412 penetrating the positioning sleeve 410, through which an LED bead 320 can pass. The distribution of the LED beads 320 on the lamp plate 310 corresponds to the positions of the lamp placement hole 412 and the lamp placement cavity 121, ensuring that each LED bead 320 can pass through its corresponding lamp placement hole 412 and be accommodated within its corresponding lamp placement cavity 121.
[0091] An isolation section 420 is disposed on the side of the positioning sleeve 410 near the optical module 100; at least one isolation section 420 is provided, which is inserted between two adjacent longitudinal light guides 130 and can fill the gap between the two adjacent longitudinal light guides 130. Figure 8A In the middle, the optical module 100 has four longitudinal light guides 130; in Figure 9 In the middle, the number of isolation parts 420 on the positioning component 400 is three.
[0092] like Figure 10A As shown, to improve the fit and aesthetics between the isolation portion 420 and the longitudinal light guide 130, the shape of the isolation portion 420 is adapted to the shape of the longitudinal light guide 130, and the circumferential contour of the isolation portion 420 has a second longitudinal arcuate edge 421 in a linear shape; and the size of the isolation portion 420 is not larger than the size of the longitudinal light guide 130, so that the second longitudinal arcuate edge 421 does not protrude beyond the first longitudinal arcuate edge 132. In some embodiments, the size of the isolation portion 420 is the same as the size of the longitudinal light guide 130, so that the second longitudinal arcuate edge 421 is flush with the first longitudinal arcuate edge 132; as Figure 8A As shown, in some embodiments, the size of the isolation portion 420 is smaller than the size of the longitudinal light guide 130, such that the first longitudinal arcuate edge 132 protrudes relative to the second longitudinal arcuate edge 421, that is, the longitudinal light-emitting area 131 of the longitudinal light guide 130 is highlighted.
[0093] In some embodiments, a reflective film or reflective sticker is attached to the second longitudinal arc-shaped edge 421, or a reflective coating is applied, so that the second longitudinal arc-shaped edge 421 can reflect light at night, achieving passive light reflection. When the power of the multi-functional bicycle tail light-emitting device 10 is insufficient, the light source assembly 300 cannot work for a long time at night. At this time, the isolation part 420 can act as a night safety indicator to improve driving safety.
[0094] Furthermore, the optical module 100 is provided with multiple first positioning parts 140 at its tail. Figure 10A In the middle, the positioning sleeve 410 has a plurality of guide holes 413 for the first positioning part 140 to pass through; in Figure 9 In the lamp panel 310, there is a second positioning part 330 corresponding to the first positioning part 140, and the second positioning part 330 is detachably connected to the first positioning part 140. For example, the first positioning part 140 is a columnar structure, and the second positioning part 330 is a hole-like structure, and the first positioning part 140 can be inserted into and fixed in the second positioning part 330; in some other embodiments, the first positioning part 140 and the second positioning part 330 are both columnar structures, and the two are inserted and fixed.
[0095] In this embodiment, the positioning component 400 can be made of materials such as thermoplastic elastomer (TPE), silicone, polyurethane (PU), natural rubber (NR), and fluororubber (FKM).

Preferably, the end of the waterproof plug 630 is movably connected to the lower housing 220 to prevent the waterproof plug 630 from being lost.
[0103] Furthermore, such as Figure 11A and Figure 11B As shown, the multi-functional bicycle tail light-emitting device 10 also includes a button trigger component 700. The control motherboard 500 has a function button 510. The button trigger component 700 is in contact with the function button 510 and is at least partially exposed on the surface of the housing 200.
[0104] Specifically, the button trigger assembly 700 is disposed on the top of the control motherboard 500. The button trigger assembly 700 includes a button cap 710, a trigger member 720, and a button pressure plate 730. The button pressure plate 730 is fixed to the top of the control motherboard 500 and has a relief groove 731 that exposes the function button 510. The trigger member 720 is disposed on the top of the button pressure plate 730 and has a trigger part 721 corresponding to the function button 510. The upper half of the trigger part 721 is a columnar structure, and the lower half is a conical part. The lower half of the trigger part 721 contacts the function button 510. The button cap 710 is installed on the upper half of the trigger part 721. The surface of the upper housing 210 is provided with a button hole 211, and the surface of the button cap 710 is exposed in the button hole 211. When the user presses the button cap 710, the trigger part 721 deforms and moves downward to trigger the function button 510.
[0105] In this embodiment, the user can perform various functions by clicking, double-clicking, or long-pressing the function button 510. For example, power on / off, brightness adjustment, and mode switching.
[0106] Furthermore, the multi-functional bicycle taillight device 10 also includes indicator lights 740. The indicator lights 740 are located on the trigger member 720 and the button plate 730 and are electrically connected to the control mainboard 500. The indicator lights 740 are exposed through indicator holes 212 on the upper housing 210. Multiple indicator lights 740 are present, and the control mainboard 500 can display the battery 600's charge percentage by the number of indicator lights 740 illuminating.
[0107] Furthermore, such as Figures 12A to 12D As shown, to facilitate the installation and removal of the multi-functional bicycle tail light-emitting device 10, the multi-functional bicycle tail light-emitting device 10 also includes a fixing component 800, wherein the fixing component 800 includes a buckle 810, a locking member 820, and a clamp 830; the buckle 810 is installed at the tail of the housing 200; the locking member 820 has a locking cavity 821 adapted to the buckle 810, and the buckle 810 can be inserted into and fixed in the locking cavity 821; the clamp 830 is movably connected to the locking member 820, and the clamp 830 is used to fix the tail of the bicycle.
[0108] Specifically, in Figure 12C In the design, the snap fastener 810 has a disc-shaped structure and multiple mounting holes 813 in its circumferential direction. Bolts pass through the mounting holes 813 to fix the snap fastener 810 to the tail of the lower housing 220. The edge of the snap fastener 810 also has two symmetrical lugs 812, each with a first locking portion 8121. The locking cavity 821 also has a second locking portion 823 that matches the first locking portion 8121. One of the first locking portion 8121 and the second locking portion 823 is a protrusion structure, and the other is a groove structure, allowing the first locking portion 8121 and the second locking portion 823 to engage and lock together. Preferably, in... Figure 12D In the middle, the first locking part 8121 is a groove structure, and the second locking part 823 is a protrusion structure.
[0109] Meanwhile, to further enhance the connection between the snap fastener 810 and the locking member 820, the snap fastener 810 also has a first engaging portion 811 on the side away from the outer casing 200, and a second engaging portion 822 adapted to the first engaging portion 811 is provided in the locking cavity 821. One of the first engaging portion 811 and the second engaging portion 822 is a locking block structure, and the other of the first engaging portion 811 and the second engaging portion 822 is a locking groove structure, so that the first engaging portion 811 and the second engaging portion 822 can be locked together. Preferably, there are two first engaging portions 811, which are symmetrical to each other; Figure 12C In the middle, the first engaging part 811 is a slot structure.
