Figure 2 is a schematic perspective view of a hardware component according to a first embodiment. Figure 3 is based on An exploded schematic diagram of the casing of the first embodiment. FIG. 4 is an assembly schematic diagram of a latch assembly assembled into a casing according to a first embodiment. Figure 5 is a schematic three-dimensional view (2) of the latch according to a first embodiment. A latch part 100 includes a hard material part 110 and a soft material part 130. The latch 100 is applied to the housing 200, for example. The casing 200 is, for example, a casing of an electronic device, and the electronic device is, for example, a notebook computer, a tablet computer, or a handheld electronic device, but the invention is not limited thereto. The assembly structure of the latch 100 and the casing 200 will be described in detail later. In Figures 1 and 3, in order to clearly distinguish the hardware component 110 and the software component 130, they are marked with dot color blocks. This is only for convenience of explanation and understanding.

As shown in FIG. 2 , the hard material component 110 includes a hard material body 111 , an elastic arm 112 and a buckle part 113 . The hard material body 111 has a first side 1111 and a second side 1112 opposite to each other. One end of the elastic arm 112 is connected to the first side 1111 of the hard material body 111, and there is at least one hollow portion 114 between the elastic arm 112 and the hard material body 111. The buckle portion 113 is connected to the other end of the elastic arm 112 . In this way, through the hollow part 114, the user can press the elastic arm 112, so that the elastic arm 112 elastically deforms relative to the hard material body 111, and the buckle part 113 is buckled into the groove of the casing 200 (details will be discussed later) .

Referring again to FIG. 1 , the soft material part 130 includes a first soft material body 131 . The first soft material body 131 is located on the first side 1111 of the hard material body 111 and covers the hollow part 114 and the elastic arm 112 . In this embodiment, the first soft material body 131 is formed on the first side 1111 of the hard material body 111 by injection molding. The first soft material body 131 covers the hard material body 111 to maintain the integrity of the latch 100 . In addition, due to the soft material characteristics of the first soft material body 131 , the deformation effect of the elastic arm 112 can also be maintained.

Specifically, the elastic arm 112 of the hard material piece 110 can elastically deform relative to the hard material body 111 through the hollow portion 114 . In order to maintain the integrity of the latch 100 , the hollow portion 114 at the first side 1111 of the hard material 110 can be covered by the soft material 130 . At this time, due to the software 130 It is elastic, so the deformation effect of the elastic arm 112 can still be maintained. In this way, through the latch component 100 that combines the hard material component 110 and the soft material component 130, the latch function can be achieved, and redundant parts and costs can be saved.

The hardware piece 110 further includes an assembly slot 118 , which is opened in the hard material body 111 of the hardware piece 110 . The assembly protrusions 1511 are correspondingly penetrated in the assembly groove 118 so that the waterproof component 150 is assembled on the hard material component 110 . In this way, when the latch member 100 is assembled in the casing 200 to close the opening 213, the waterproof member 150 sandwiched therein can enhance the sealing effect on the opening 213 and improve the waterproof performance.

As shown in FIGS. 3 and 4 , in this embodiment, the waterproof component 150 further includes a waterproof ring 152 , and the waterproof ring 152 surrounds the periphery of the waterproof component body 151 . The waterproof ring 152 is, for example, rubber. The rubber waterproof ring 152 surrounds the waterproof component body 151 so that when the latch 100 is assembled in the casing 200, the opening 213 of the latch 100 and the casing can be further filled with the waterproof ring 152. The gap between 200 and 200mm further increases the waterproof effect.

As shown in FIG. 5 , in this embodiment, the latch member 100 further includes a decorative member 170 , and the decorative member 170 is disposed on the hard material body 111 of the hard material member 110 . The decorative component 170 is used to cover the assembly groove 118 of the hardware component 110 .

As shown in FIGS. 1 and 4 , in this embodiment, the casing body 210 further includes a locking portion 212 , and the locking portion 212 is located on the opposite side of the recess 211 . The soft material piece 130 further includes a second soft material body 132 . The second soft material body 132 is located on the second side 1112 of the hard material body 111 . The second soft material body 132 is provided with a hole 1321 . The hole portion 1321 is correspondingly formed in the locking portion 212 . In this way, the latch 100 can be fixed to the casing 200 through screw locks or other methods to increase the stability of assembly. In this embodiment, the second soft material body 132 is also injection molded on the hard material body 111 .

See Figure 6. Figure 6 is an exploded schematic view of a latch according to a second embodiment. The structures of the second embodiment that are similar to those of the first embodiment will not be described again. In the first embodiment, the second soft material body 132 is formed on the second side 1112 of the hard material body 111 by injection molding, and the hole 1321 is provided therein for locking the latch 100 . However, Not limited to this. In this embodiment, a separate component may also be used to be combined with the hard material body 111 of the hard material component 110 to lock the latch 100 .

As shown in FIG. 6 , the latch 100a further includes a middle piece 120 , the hard material piece 110 is assembled on the middle piece 120 , and the middle piece 120 includes a body 121 , an assembly end 122 and a hole 123 .
