There are at least two glue tanks 1 , wherein at least two tanks 1 are spaced apart in the inner and outer directions of the tray 10 and extend circumferentially along the chamber 101 .

In this technical solution, at least two adhesive tanks 1 are formed on the joint surface 102 of the tray 10 for combining with the tray cover, and at least two glue tanks 1 are spaced apart in the inner and outer directions of the tray 10 and It extends along the circumference of the chamber 101. Therefore, a sealing joint glue can be disposed in the glue tank 1 . For example, a sealant (also having a fixed connection function) is disposed in the glue tank 1 of the outer ring, and the glue tank of the inner ring is provided. A fixing adhesive (also having a sealing function) is provided in the inside, so that the tray cover 9 can be reliably fixedly connected and sealed by at least two glues 2 and the tray 10. In other words, the tray cover 9 is covered on the tray 10, and by providing the glue 2 between the tray cover 9 and the tray 10, the tray cover 9 is sealed and connected to the tray 10. In this way, the step of screwing is omitted, and the processing and assembly process is reduced. At the same time, the plastic tank 1 of the outer ring and the colloid (such as sealant) can protect the inner tank of the glue tank 1 and the colloid (such as the fixed joint glue), so that the glue tank 1 and the inner and outer rings are The cooperation of the colloid 2 further ensures the reliability of the connection between the plastic tank 1 and the colloid 2 of the inner ring to the tray 10 and the tray cover 9.

It should be understood that the tray 10 of the present application may have various structural forms, and the bonding surface 102 also has different positions correspondingly. For example, in one structural form, the tray 10 includes an inner casing and an outer casing, and The chamber 101 is formed in the casing, and at this time, the top surface of the outer casing can be combined with the tray cover 9 as the joint surface 102.

Alternatively, in another configuration, the tray 10 includes a single side wall 103, that is, the top surface 104 of the side wall 103 of the chamber 101 serves as the joint surface 102. At this time, at least two adhesive tanks 1 are formed in the cavity. On the top surface 104 of the side wall 103 of the chamber 101, as long as the strength of the side wall 103 of the chamber 101 is satisfactory, the top surface 104 of the side wall 103 of the chamber 101 can be utilized to engage the tray cover 9. And/or at least two plastic tanks 1 have the same width and extend in parallel to facilitate processing, and at the same time, the colloids provided in the inner and outer tanks can be the same, which can facilitate the formation of the tray 10 and the tray cover 9 in the circumferential direction. Continuously stable and reliable connection.

It should be noted that the tray 10 of the present application can be separately manufactured and can be supplied to the production line for dispensing after the manufacturing is completed. Before the dispensing operation, the glue tank 1 is not provided with the colloid 2; or The tray 10 can be provided with a colloid in the glue tank 1 during the manufacturing process. The glue 2 can be bonded when the tray 10 and the tray cover 9 are combined or can be heated to achieve bonding.

Therefore, in some embodiments, as shown in FIG. 1 , at least two adhesive tanks 1 are provided with a colloid 2, and in order to facilitate the bonding of the tray 10 and the tray cover 9 by the colloid 2, wherein, as shown in FIG. The depth of the plastic tank 1 is smaller than the height of the colloid 2, that is, the colloid 2 is higher than the tank 1 so that, as shown in FIG. 2, the tray cover 9 can press the top of the colloid 2, so that the colloid 2 is inward and outward. The side overflows to increase the bonding area between the tray 10 and the tray cover 9.

Of course, the colloid 2 can be appropriately raised above the glue tank 1. If it is too high, when the tray cover 9 and the tray 10 are combined, the compression amount of the colloid 2 is too large and is in an ultra-compressed state for a long time, so that the fatigue strength is increased. It is easy to fail. If it is too low, the compression amount of the colloid 2 may be insufficient to cause the seal to fail. Therefore, in a preferred embodiment, the depth of the glue tank 1 is 45%-85% of the height of the colloid 2, preferably The ground is 50% so that when the tray cover 9 and the tray 10 are combined, the glue 2 will be effectively compressed to provide a sufficient seal while not being in an ultra-compressed state.

and / or,

For example, the colloid 2 includes a sealant (also a certain connection function) disposed in the glue tank 1 of the outer ring and a fixed joint adhesive disposed in the glue tank 1 of the inner ring (also serves as a sealing function, Only the side focus is slightly different. In this way, the fixed joint adhesive of the inner ring mainly plays a fixed bonding role, and the sealant of the outer ring mainly plays a sealing role, so as to play a good protective effect on the fixed joint adhesive of the inner ring. .

In addition, the top surface of the colloid 2 may be a flat surface, or, as shown in FIG. 1, the top surface of the colloid 2 is an inclined surface 3 extending obliquely downward from the middle to the both sides, so that when compressed, the colloid 2 The top portion is appropriately overflowed to both sides, thereby preventing the excessive colloid 2 from overflowing to both sides, particularly to the outside (that is, the left side of FIG. 1) and overflowing from the gap between the tray 10 and the tray cover 9.

In addition, in order to facilitate the stable and reliable mounting of the tray 10, as shown in FIG. 1, the outer peripheral surface of the tray 10 is formed with an outwardly extending portion 4 extending in the circumferential direction, and the lower surface of the outwardly extending portion 4 is formed. To install the step surface 5. Thus, when the tray 10 is installed, the mounting step surface 5 can be overlapped on the mounting base, and the fixed support of the mounting step surface 5 by the mounting contact can achieve stable and reliable fixed positioning of the tray 10.

In some embodiments, as shown in FIG. 1, in order to make full use of the upper surface of the outwardly extending portion 4, preferably, the joint surface 102 includes an upper surface of the outwardly extending portion 4, that is, an outwardly extending portion. The upper surface of the upper surface 104 of the chamber 101 is flush with the top surface 104 of the side wall 103 of the chamber 101, so that the glue receiving groove 1 can also be formed on the upper surface of the outwardly extending portion 4.

In addition, in some embodiments, circumferentially extending grooves 6 are formed between the plastic tanks 1, as shown in FIG. 1, so that when the inner and outer rings of the colloid 2 are squeezed, too much colloid will overflow into the In the groove 6, the colloid is prevented from being transiently compressed due to excessive dispensing.

In some embodiments, as shown in FIG. 3, the groove 6 is disposed in parallel with the glue tank 1 so that the excess colloid is evenly distributed in the circumferential direction when the glue 2 pinched by the glue tank 1 is squeezed. It overflows into the groove 6. Of course, the groove 6 may also not extend parallel to the glue tank 1 .

Alternatively, the surface of the space between the plastic tanks 1 is formed as a flat surface 7, as shown by the straight dashed line in Fig. 1, so that when the colloid 2 of the inner and outer rings is pressed, too much colloid will overflow into the plane. 7 to increase the connection sealing surface.

Alternatively, in some embodiments, the spaced surfaces between the glue tanks 1, such as the two sol tanks 1, are formed as upwardly convex and circumferentially extending curved faces 8, as shown by the curved dashed lines in FIG. Thus, when the inner and outer ring colloids 2 are squeezed, too much colloid will be squeezed into the gap between the tray cover 9 and the curved surface (as shown in FIG. 2), so that a small amount can be used. The colloid can both increase the joint sealing surface.

In addition, the present application provides a power supply device 30, such as the partial structure shown in FIG. 2, which includes a tray cover 9, a power source 31, and a tray 10 of any of the above, wherein the power source 31 is disposed in the cavity of the tray 10.
