Key modules are commonly used in electronic devices, and key modules typically mount keys using screw fixation. However, the conventional key module may be erroneously installed when actually installed. This would result in the keys being removed and reinstalled, greatly reducing production efficiency.

The inventor of the utility model finds through research that when the key module is installed, workers usually pay little attention to whether the gesture of the key is accurate or not, but pay little attention to whether the key module can be normally used or not, but the error installation of the key module can cause abnormal marks of the key, and the attractive appearance of products is affected.

In view of this, the present utility model proposes a projector including a key module, and any projector including the key module described in the present utility model belongs to the projector proposed in the present utility model. Fig. 1 to fig. 4 are schematic structural diagrams of a key module according to an embodiment of the utility model.

Referring to fig. 1 to 4, a key module 100 according to the present utility model includes a housing 1 and a key 2. The housing 1 is provided with at least two mounting posts 11 and a through hole 12, the shape or size of the at least two mounting posts 11 being different. The key 2 includes a key main body 21 adapted to the through hole 12, and a mounting portion 223 provided on the key main body 21. The mounting portion 223 is provided with at least two mounting holes 23 corresponding to the mounting posts 11 one by one, and each mounting hole 23 is used for the corresponding mounting post 11 to penetrate. Wherein, at least two mounting posts 11 and at least two mounting holes 23 are used for cooperation to enable the key main body 21 to be mounted on the through hole 12 in a preset pose.

In practice, the shape and size of at least two mounting posts 11 may be different at the same time, thereby making the variability between mounting posts 11 greater, thereby further avoiding the occurrence of mounting errors.

In the technical scheme of the utility model, the key module 100 comprises a housing 1 and a key 2, wherein a through hole 12 for installing the key 2 is arranged on the housing 1, and a key main body 21 of the key 2 can extend to the other end of the housing 1 when being installed in the through hole 12 for being touched by a user. Specifically, the key main body 21 is provided with a mounting hole 23 corresponding to the mounting post 11, and when the key main body 21 is mounted, the mounting post 11 is matched and fixed with the mounting hole 23. The at least two mounting posts 11 have different shapes or sizes, so that the at least two mounting posts 11 cannot extend into the wrong mounting holes 23, thereby ensuring that the key main body 21 can only be mounted in a preset posture and avoiding the problem that the key module 100 is difficult to reinstall due to misloading. The mounting posts 11 are arranged in one-to-one correspondence with the mounting holes 23, and the specific number of the mounting posts 11 can be adjusted according to actual requirements. The present utility model increases the installation efficiency by providing the installation posts 11 having different shapes or sizes so that the key main body 21 cannot be installed in an erroneous posture.

Referring to fig. 3 and 4, in some embodiments, an outer diameter of one mounting post 11 of at least two mounting posts 11 is larger than an outer diameter of the other mounting posts 11. In a specific application, if the shape and size of at least two mounting posts 11 are set to be different, the difficulty and cost of production will be greatly increased. In practice, only one of the at least two mounting posts 11 has to have an outer diameter larger than that of the remaining mounting posts 11, which would prevent the mounting post 11 having the largest outer diameter from being mounted in the other mounting hole 23, so that the mounting having the largest outer diameter would only be mounted in its corresponding mounting hole 23, and the positions of the other mounting posts 11 would be fixed, thereby ensuring that the key main body 21 is mounted in a predetermined posture.

In some embodiments, the housing 1 is provided with a mounting post 11. When the housing 1 has only one mounting post 11, the mounting post 11 is unlikely to have a mounting error, and the key main body 21 can be mounted in only a preset posture at this time, and cannot be mounted in other postures.

In some embodiments, the mounting post 11 is protruding on the inner side of the housing 1 and includes a cylindrical portion penetrating through the corresponding mounting hole 23, and a hot-melting portion connected to an end of the cylindrical portion away from the housing 1, where the hot-melting portion is used to penetrate through and extend out of the corresponding mounting hole 23 and then is hot-melted, so as to form a fixing portion on a side of the cylindrical portion away from the housing 1, and the fixing portion is limited on a side of the mounting portion 223 away from the housing 1.

When the key main body 21 is specifically mounted, each mounting hole 23 on the key main body 21 is aligned with the corresponding mounting column 11, so that each mounting column 11 extends into the corresponding mounting hole 23, and the key main body 21 is in a preset posture. Thereafter, the heat-melted portions in the respective mounting posts 11 are protruded from the corresponding mounting holes 23, and then the heat-melted portions are heat-melted. After the hot-melt portion is hot-melted, the shape is changed, so that the mounting hole 23 cannot be re-entered, and the column portion of the mounting column 11 cannot be withdrawn from the mounting hole 23, that is, a fixing portion is formed at a side of the column portion facing away from the housing 1. Compared with a screw-fixed mounting mode, the hot-melt mounting can greatly reduce the required mounting space, and is suitable for mounting some special modules.

Referring to fig. 4, in some embodiments, the key module 100 further includes a connecting arm 22, one end of the connecting arm 22 is connected to the key main body 21, and the other end is provided with a mounting portion 223. In practical application, the key main body 21 is mounted in the through hole 12, and the mounting post 11 cannot be obviously disposed in the through hole 12, so that the mounting post 11 is difficult to extend into the corresponding mounting hole 23. Therefore, the key body 21 needs to be additionally provided with the connecting arm 22 and the mounting portion 223 is arranged on the connecting arm 22, so that the key body 21 can be provided with the mounting hole 23 on the connecting arm 22, and the mounting hole 23 can be close to the corresponding mounting column 11, thereby facilitating the mounting.

In some embodiments, the connection arm 22 includes a first section 221 having one end connected to the key main body 21 and a second section 222 connected to the other end of the first section 221. The second section 222 surrounds the key main body 21 and is disposed at a distance from the key main body 21, and an installation portion 223 is disposed at an end of the second section 222 away from the first section 221. Specifically, when the user presses the key main body 21, the key main body 21 receives a force in the axial direction of the through hole 12, and the key main body 21 also needs to be movable in the axial direction of the through hole 12 to signal other structures. In the present embodiment, when the key main body 21 moves along the axial direction of the through hole 12, the second section 222 deforms to a certain extent, so that the key main body 21 can perform a certain extent of movement. When the user finishes pressing, the second section 222 will drive the key body 21 to reset together.

Note that, when the length of the second section 222 is larger, the elasticity of the second section 222 is more remarkable, and the key main body 21 is also more easily movable. The second section 222 surrounds the key main body 21 and is arranged at intervals with the key main body 21, and compared with the straight line arrangement, the surrounding arrangement can enable the second section 222 and the key main body 21 to be relatively movable more easily, namely the elasticity of the second section 222 is more obvious, and the key main body 21 is also movable more easily.

In some embodiments, the key module 100 includes two connecting arms 22, and the apertures of the mounting holes 23 on the mounting portions 223 on the two connecting arms 22 are different. The different diameters of the mounting holes 23 on the mounting portions 223 on the two connecting arms 22 indicate that the diameters of the corresponding mounting posts 11 of the two mounting holes 23 are different, thereby ensuring that the key main body 21 is not subject to mounting errors. In addition, when the connecting arm 22 is provided in two or more, the connection between the key main body 21 and the housing 1 is tighter and more stable.

In some embodiments, the mounting portions 223 on the two connecting arms 22 are symmetrically distributed about the key main body 21, which makes the two mounting holes 23 also symmetrically distributed about the center, so that the connection positions between the key 2 and the housing 1 are uniformly distributed, and the connection stability between the key 2 and the housing 1 is further improved.

In particular use, the user presses the key main body 21 so that the key main body 21 moves in the axial direction of the through hole 12. In fact, the key main body 21 is moved by the elasticity of the connecting arm 22, and the connecting arm 22 can reset the key main body 21 by its own resilience, and during the resetting, the connecting arm 22 may cause the key main body 21 to protrude from the through hole 12 to the outside of the housing 1. Thus, in some embodiments, the key 2 further includes a flange 24 surrounding the periphery of the key body 21, and the flange 24 is limited to the inner side of the housing 1, so as to limit the key body 21 in the through hole 12.

The present utility model also proposes a projector comprising a key module 100 as described in any of the above embodiments. The projector has a small internal space, and the key 2 cannot be mounted in a screw-connection manner, so that the key module 100 according to the present utility model is mounted by means of hot melting. Of course, the key module 100 may be installed in other electronic devices, and only the installation structure needs to be adjusted adaptively.

In addition, the utility model also provides an electronic device, which comprises the key module 100 in any embodiment. The electronic device can be provided with a control instruction input by a user through the key module 100, and the key module 100 improves the installation efficiency by avoiding installation errors, thereby increasing the production efficiency of the electronic device to a certain extent.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
