As a further improvement of the present invention, annular seal pocket includes slot bottom part and slot-open-section.Slot-open-section is under Successively narrow upwards, forms guiding surface in notch two sides.
It is arranged by using aforesaid way, further increases liquid resistance when liquid state colloid flows through seal groove, it is close to improve its Seal reliability.
As a further improvement of the present invention, guiding surface is cambered surface
Arc trajectory is formed when liquid state colloid flows through the guiding surface of arc surfaced, and extends road to a certain extent Diameter increases its linear loss.
As a further improvement of the present invention, the quantity of annular seal pocket is at least one.
As a further improvement of the present invention, the quantity of annular seal pocket is set as two rules, and along it is radial, from extroversion Its interior groove depth is sequentially reduced.
As a further improvement of the present invention, the groove width of each annular seal pocket is consistent, and is greater than two adjacent annular seals The spacing of slot.
It is arranged by using aforesaid way, the resistance coefficient of seal groove can be further increased, further decreases flash amount.
As a further improvement of the present invention, the bottom of annular seal pocket is provided with v-depression.
It is arranged by using aforesaid way, enables and form turbulent flow or even whirlpool when liquid state colloid flows through annular seal pocket Rotation, increases its energy loss, to reduce the flash amount of wireless charger upper cover.
As a further improvement of the present invention, v-depression is located at the center of its corresponding annular seal groove width.V The angle of connected in star is 30~60 °, and its depth is not less than 0.3mm.
It is arranged by using aforesaid way, further enhances turbulent flow effect.
As a further improvement of the present invention, the angle of v-depression is 45 °, and its depth is 0.5mm.

Specific embodiment
Combined with specific embodiments below, the contents of the present invention are described in further detail.It is anti-that Fig. 1 shows the present invention The stereoscopic schematic diagram of flash wireless charger upper cover is constituted by bottom wall 1, and around the side wall 2 of the bottom wall.It is mutually fitting therewith Protrusion compatible with the wireless charger upper cover shape is provided in the plastic mould front cavity matched, side wall 2 presses in preceding mould In benevolence, flexible glue layer injection die cavities are formed between rear cavity and wireless charger upper cover in in-mould injection liquid state colloid makes it Thermoset forming.
Fig. 2, Fig. 3 respectively illustrate the structural schematic diagram of anti-the first embodiment of flash wireless charger upper cover of the present invention And partial enlarged view, the inside of the side wall 2 of the wireless charger upper cover is provided with the annular platform 21 to lower recess, depth is 0.5~2mm, and an annular seal pocket 211, rectangular in cross-section are offered in the annular platform 21, depth is 1~2mm, wide Degree is not less than 1mm.In this way, which liquid state colloid resistance when flowing through annular seal pocket 211 increases, its own flow velocity is slowed down, Liquid state colloid generates more energy dissipations in flow process, to advantageously ensure that the sealing of wireless charger upper cover itself Property, reduce flash amount.
Certainly, the cross sectional shape of above-mentioned annular seal pocket 211 may be set to be arc or isosceles trapezoid etc..In order into one Step improves the anti-flash effect of wireless charger, which can be set to 2 or a plurality of, arranged concentric.
Fig. 4, Fig. 5 respectively illustrate the structural schematic diagram of second of embodiment of anti-flash wireless charger upper cover of the invention And the difference of the wireless charger upper cover in partial enlarged view, with the first implementation is: 1) increasing annular seal pocket 211 Quantity, be set as 2 in this embodiment;2) annular seal pocket 211 is divided into slot bottom part 2112 and slot-open-section 2113, And slot-open-section 2113 successively narrows from bottom to top, forms guiding surface 21131 in 2113 two sides of slot-open-section.3) cyclic annular close The bottom of sealing groove 211 is provided with v-depression 2111.The purpose of above-mentioned setting is to increase the resistance coefficient of seal groove, into one Step reduces flash amount.It illustrates herein a bit, the purpose of setting v-depression 2111 is so that when liquid state colloid flows through ring-type Turbulent flow can be formed when seal groove 211, or even is vortexed, its energy loss is increased, to reduce overflowing for wireless charger upper cover Doses.In order to obtain preferable anti-flash effect, v-depression can refer under type such as and be configured: the angle of v-depression 2111 It is 30~60 °, and its depth is not less than 0.3mm, and its own is located at the centre bit of its corresponding 211 width of annular seal pocket It sets.
Furthermore the groove width of each above-mentioned annular seal pocket 211 itself is consistent, and is greater than two adjacent annular seal pockets 211 Spacing.
Finally, in order to increase when liquid state colloid flows through annular seal pocket 211 along journey energy loss, be set to slot-open-section 2113 guiding surface 21131 can be designed as arc.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one The widest scope of cause.
