Detailed Description
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying fig. 1 to 7. The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.
In the exemplary preferred embodiments described below, the housing for electronic devices according to the present invention is exemplarily shown as the housing 1 for a stand-alone power conversion driving apparatus, however, it should be understood that the housing for electronic devices according to the present invention is not limited to this specific application field, but may be used as a housing for housing, enclosing any suitable electronic device or apparatus.
Fig. 1 shows a partially exploded perspective view of a housing 1 for an electronic device according to a preferred embodiment of the present invention. The housing 1 in the present embodiment is used for a stand-alone power conversion driving device, and in the prior art, the stand-alone power conversion driving device generally includes an electronic device, a cable connection terminal (not shown) and the like located inside the housing 1, and can be used for electrically connecting with an electrical appliance such as an LED and the like, so as to provide power conversion and driving functions for the electrical appliance. As shown in fig. 1, a housing 1 of a stand-alone power conversion driving apparatus generally includes: a case 12 and two covers 14, the case 12 including a case body 122 and two engaging portions 124 extending from the case body 122 to both ends for engaging the two covers 14, the two covers 14 being detachably mounted to the two engaging portions 124 so that an operator can access the electronic devices inside the housing 1 through the two engaging portions 124. In particular, for a stand-alone power conversion driving device, a power converter and its related electronic devices (not visible in the drawings) are generally installed in the case body 122, and it is possible to connect and disconnect cables to and from the electronic devices (power converters and the like) in the case 1 via two joints 124 by removing the two covers 14, wherein the cable connected to one joint 124 (for example, the joint 124 on the left side in fig. 1) is also electrically connected to an external power supply, and the cable connected to the other joint 124 (for example, the joint 124 on the right side in fig. 1) is also electrically connected to an electrical appliance such as an LED lamp, thereby providing power conversion and driving functions for the electrical appliance.
It should be understood that, as the housing 1 for the stand-alone power conversion driving device, the overall configuration of the housing 1 shown in fig. 1 is merely exemplary, and the positional relationship between the housing body 122 and the two engaging portions 124 may also be changed according to practical applications, for example, the two engaging portions 124 may be disposed on the same side of the housing body 122, and the like, and the number of the engaging portions 124 may also be three, four, or more, which may be adjusted by one of ordinary skill in the art according to practical needs. Also, when the housing for an electronic device according to the present invention is used for other types of electronic devices or apparatuses, it is apparent that the housing may include only one engaging portion 124 and one cover 14.
As described above, for some housings for electronic devices, different usage environments and different regions have different requirements and safety standards for convenience in mounting and dismounting and reliability in closing, and it is difficult for the prior art housings for electronic devices to achieve a good balance between convenience in mounting and dismounting and reliability in closing and to satisfy various safety standards for different usage environments and different regions at the same time. In order to solve the technical problem, the invention improves the configuration of the housing for the electronic device, and in general, the housing for the electronic device is designed to adopt the configuration of combining the shape matching installation and the spare fastener installation so as to simultaneously meet various safety standards of different use environments and different regions. The specific configuration of the housing 1 for electronic devices of the present invention will be described in detail below with reference to fig. 2 to 7.
Fig. 2 shows a perspective view of the cover 14 of the housing 1 in fig. 1; fig. 3 shows a perspective view of the housing 12 of the housing 1 from fig. 1. As shown in fig. 2 and 3, the cap 14 specifically includes a cap body 142 and two opposite first sidewalls 144 (only one first sidewall 144 can be seen in fig. 2) extending perpendicularly from the cap body 142, the two first sidewalls 144 include first inner lateral surfaces 1441 (see fig. 4) opposite to each other and first outer lateral surfaces 1442 facing away from each other, and the first outer lateral surfaces 1442 of the two first sidewalls 144 each include a first fitting portion 146. As shown in fig. 3, correspondingly, the joining portion 124 of the housing 12 includes a bottom wall 126 and two opposite second side walls 128 extending perpendicularly from the bottom wall 126, the two second side walls 128 include second inner side surfaces 1282 opposite to each other and second outer side surfaces 1284 facing away from each other, the second inner side surfaces 1282 of the two second side walls 128 each include a second mating portion 129, and when the cover 14 is mounted to the joining portion 124, the first outer side surfaces 1442 of the two first side walls 144 can abut against the second inner side surfaces 1282 of the two second side walls 128, so that the first mating portions 146 and the second mating portions 129 form a form-fitting engagement with each other, thereby snapping the cover 14 to the housing 12. Specifically, the first fitting portion 146 and the second fitting portion 129 include concave-convex fitting portions that match each other, and when the cover 14 is mounted to the housing 12, as the first outer side surfaces 1442 of the two first side walls 144 and the second inner side surfaces 1282 of the two second side walls 128 come into abutting engagement, the concave-convex fitting portions of the first fitting portion 146 and the concave-convex fitting portions of the second fitting portion 129 are abutted, and in order to achieve the concave-convex shape fitting therebetween, at least the two first side walls 144 and/or the two second side walls 128 may be configured to be elastically deformable (for example, made of an elastically deformable plastic material) — preferably, in the present embodiment, the housing 1 is made of an elastically deformable plastic material as a whole, whereby the two first side walls 144 and/or the two second side walls 128 are elastically deformable so that the abutting concave-convex fitting portions come into an engaging position of the concave-convex fitting with each other, thereby securely mounting the cover 14 to the housing 12.
In order to be able to easily remove the cover 14, two actuating portions 13 are also provided, the two actuating portions 13 preferably being provided on the two second side walls 128 for actuating the two first side walls 144, respectively. The actuating portion 13 is configured to be displaceable under an external force to actuate the first sidewall 144 to disengage the first and second mating portions 146, 129 away from each other to release the lid 14. As shown in fig. 3, the actuating portion 13 is preferably integrally formed with the second side wall 128 as: a portion of the actuating portion 13 is separated relative to the second side wall 128 to enable the actuating portion 13 to be displaced relative to the second side wall 128, as shown in fig. 3, with the lower edge of the actuating portion 13 adjacent the bottom wall 126 being connected to the second side wall 128 and the remaining portion being separated from the second side wall 128 by a slot 130, it being understood that the actuating portion 13 may be configured to be connected to the second side wall 128 at different locations, i.e., the location, shape and size of the slot 130 may be varied as desired. This configuration of the actuating portion 13 enables the cover 14 to be actuated directly from the outside of the housing 1 without accessing the components inside the housing 1 (the first side wall 144 and the first fitting portion 146), making the operation very convenient, and by providing the actuating portion 13, the first side wall 144 and the first fitting portion 146 can be completely enclosed within the housing 1 without being exposed to the outside, further improving the integrity and the aesthetic appearance of the housing 1.
With further reference to fig. 3, the actuating portion 13 specifically includes an actuating surface 132 located on the second inner side surface 1282 of the second side wall 128 and a pressing surface 134 located on the second outer side surface 1284, and the actuating surface 132 can abut against and actuate the first side wall 144 of the cap 14 by an external force acting on the pressing surface 134. The pressing surface 134 is preferably flush with the second outer side surface 1284, thereby preventing an erroneous operation of actuating the cover 14 by accidentally pressing the actuating portion 13 and making the structure of the housing 1 more integrated with a higher aesthetic appearance.
It should be understood that although the actuation portion 13 in the preferred embodiment described above has a configuration integrally formed with the second side wall 128, it is contemplated that the actuation portion 13 may be a separate component from the second side wall 128 — for example, may be made of an elastically deformable component, and connected to the second side wall 128 by any suitable means such as bonding, riveting, or the like and may be displaced or deformed relative to the second side wall 128 to actuate the first side wall 144 as described above. A person skilled in the art will be able to carry out the relevant modifications.
Preferably, referring to fig. 1, the housing 1 has a transverse direction as indicated by an arrow a in fig. 1, the two first side walls 144 of the cover 14 and the two second side walls 128 of the housing 12 are configured parallel to each other and perpendicular to the transverse direction a, and preferably, the two first fitting portions 146 are aligned with each other in the transverse direction a, the two second fitting portions 129 are aligned with each other in the transverse direction a, and the two actuating portions 13 are aligned with each other in the transverse direction a. The arrangement is more convenient to operate and attractive.
This will be described in detail with reference to fig. 4 to 6, with respect to the above-described concave-convex engagement portions of the first engagement portion 146 and the second engagement portion 129, and the shape engagement and the actuation disengagement therebetween.
Fig. 4 shows a cross-sectional view of the housing 12 of the casing 1 and the cap 14 in fig. 1, taken along a position where the mating concave-convex portions of the first mating portion 146 and the mating concave-convex portions of the second mating portion 129 mate. In a preferred embodiment of the present invention, one of the first fitting portion 146 and the second fitting portion 129 may include one convex portion, the other of the first fitting portion 146 and the second fitting portion 129 may include at least one concave portion to be fitted with the one convex portion, and more preferably, as shown in fig. 4 and 1, the second fitting portion 129 includes one convex portion, for example, a rib extending parallel to the bottom wall 126 along the second inner side surface 1282 of the second side wall 128 of the engaging portion 124, the first fitting portion 146 includes a plurality of concave portions, for example, a plurality of engaging grooves extending parallel to the first side wall 144 of the cap 14, and as the two first side walls 144 of the cap 14 are engaged to the two second side walls 128 of the engaging portion 124, the one convex portion of the second fitting portion 129 may be sequentially engaged into the plurality of concave portions of the first fitting portion 146, thereby defining a plurality of different engaging positions, respectively. As can be seen from fig. 1 to 3, in the case 1 for the power conversion drive device of the present embodiment, this design, which defines a plurality of different engagement positions, is advantageous, in particular, as shown in fig. 1, the front end of the cover body 142 of the cover 14 includes two first recesses 1420, the front end of the engagement portion 124 of the housing 12 includes two second recesses 1240, when the cover 14 is mounted to the junction 124, the two first grooves 1420 are respectively aligned with the two second grooves 1240 to define wire holes for receiving wires, in practice, the thickness of the cable may vary from application to application, by defining a plurality of different engagement positions as described above, the mounting position of the cover 14 relative to the engagement portion 124 can be adjusted, and thus the size of the wire aperture defined by first groove 1420 and second groove 1240, thereby facilitating a better retention or capture of the wire. More preferably, as shown in fig. 3, the second groove 1240 of the housing 12 is configured as a saw-tooth shape, so that the cable can be better held or caught, preventing the cable from coming out.
Fig. 5 shows a partial perspective view of the housing 12 of the housing 1 from fig. 1. As shown in fig. 5, the actuating surface 132 of the actuating portion 13 preferably includes two ribs 136 protruding from the actuating surface 132, and end surfaces of the two ribs 136 are used to push against the first side wall 144 of the cover 14 to actuate the first side wall 144.
Fig. 6 shows another cross-sectional view of the housing 12 of the housing 1 in fig. 1 with the cover 14 mounted together, taken along the position where one rib 136 of the actuation portion 13 abuts the first side wall 144. As shown in fig. 6, the first side wall 144 includes a distal-most end 1440 away from the cap body 142, and the first outer side surface 1442 of the first side wall 144 includes a driving surface 1446 for abutting the actuating surface 132 of the actuating portion 13, more preferably for abutting the two ribs 136 of the actuating portion 13, preferably the driving surface 1446 extends to the distal-most end 1440 and is formed as a slope that gradually recedes as it extends toward the distal-most end 1440. Such a drive surface 1446 of concave ramp configuration can generate a reverse force toward the cap body 142 of the cap 14 (i.e., opposite to the receiving direction in which the cap 14 is received into the engagement portion 124) when actuated by the actuating portion 13, so that the cap 14 can be automatically ejected from the engagement portion 124 under the reverse force when the actuating surface 132 or the two ribs 136 of the actuating portion 13 push the drive surface 1446 to disengage the first mating portion 146 from the second mating portion 129, thereby being more convenient.
More preferably, although not shown in the figures, in embodiments where the actuating face 132 of the actuating portion 13 is adapted to abut and urge the drive face 1446, the actuating face 132 may include a ramp that follows the slope of the drive face 1446; alternatively, in embodiments where the actuating surface 132 of the actuating portion 13 includes two ribs 136 and the driving surface 1446 is abutted and urged by end surfaces of the two ribs 136, the end surfaces of the ribs 136 may be formed as slopes that follow the slope of the driving surface 1446. This can better provide the opposing force to the lid 14, facilitating separation of the lid 14 from the engagement portion 124.
The above details describe the relative structure of the removable form-fitting mounting, which is structurally simple, easy to operate, can be implemented without the aid of additional tools, and has a higher aesthetic and better reliability, better able to satisfy applications requiring a higher convenience of closing/opening the casing.
Further, in order to be able to meet the safety standards for applications requiring higher reliability of closure, such as for example some fields of application or geographical requirements, which require the use of tools to open the housing, the housing 1 according to the invention also comprises a spare fastener mounting structure. The spare fastener mounting structure in the housing 1 will be described in detail below with reference to fig. 1 to 3 and 7.
As shown in fig. 1-3, the cover body 142 of the cover 14 further includes a first spare mounting hole 147 therein, the bottom wall 126 of the engagement portion 124 of the housing 12 further includes a second spare mounting hole 127 therein, and the first spare mounting hole 147 and the second spare mounting hole 127 are configured to be aligned with each other after the cover 14 is mounted to the housing 12 to form a spare mounting portion that is capable of being fixedly coupled by a spare fastener. It is contemplated that the first and second alternate mounting holes 147, 127 may be provided at other locations on the cover 14 and housing 12, respectively, so long as a secure attachment of the cover 14 and housing 12 with fasteners is achieved.
More preferably, as shown in fig. 3, a spare fastener holder 125 is further included on a bottom wall 126 of the engaging portion 124 of the housing 12, and the spare fastener holder 125 may be configured to hold at least one spare fastener.
