Description

Arrangement for an environmental monitoring device

Technical Field

The present disclosure relates to an arrangement for an environmental monitoring device.

Background

In many application scenarios, it is desirable to monitor the environment and collect data from the environment to aid the user in analysis and decision making. Environmental monitoring devices that accomplish such tasks are often left outdoors for long periods of time and therefore have waterproof requirements for the environmental monitoring devices to protect against weather effects such as rain, snow, etc. Waterproof requirements are often present at the mating structures of components passing through the through-hole of the housing, such as connectors or keys, with the through-hole in order to protect the electronics disposed inside the environmental monitoring device from external weather. Furthermore, since connectors or keys are often of different sizes, adaptations are also required for these different sizes.

Disclosure of utility model

It is therefore an object of the present disclosure to provide an arrangement for an environmental monitoring device, by means of which good waterproof protection can be achieved for electronics arranged inside the environmental monitoring device. Furthermore, by means of this arrangement, the dimensions of the through-going part passing through the housing through-hole can be adapted.

According to the present disclosure there is provided an arrangement for an environmental monitoring device, the arrangement comprising: a waterproof housing; a circuit board disposed inside the housing; and at least two through-parts configured for connecting an inner member of the environmental monitoring apparatus with an outer member and/or for manipulating the inner member of the environmental monitoring apparatus from the outside, the at least two through-parts passing through respective through-holes of the housing, the respective ends of the at least two through-parts being coupled to the circuit board; the circuit board is characterized in that each through hole has a corresponding step, each through part has a corresponding flange on the peripheral surface, the corresponding flange of each through part can be arranged at the corresponding step of the corresponding through hole, a sealing structure can be constructed between a first surface facing the inside of the shell and a second surface facing the outside of the shell of the corresponding flange, wherein the depth spacing between the first surface and the inner side surface of the shell is respectively designed in such a way that in the assembled state, the protruding amount of each through part protruding from the inner side surface of the shell is the same, and the parts of each through part coupled to the circuit board are mutually flush, so that the circuit board can be flatly arranged on each through part.

With the arrangement according to the disclosure for an environmental monitoring device, in particular with the step according to the disclosure, it is possible on the one hand to achieve a sealing between the housing and the through-parts passing through the through-holes, and on the other hand to provide that the circuit boards arranged on the respective through-parts are arranged flat, in particular parallel to the inner side of the housing.

In some embodiments, one of the at least two through parts may be configured as a connector for connecting an inner member with an outer member of the environmental monitoring device, and between a first face of the respective step and a second face of the respective flange, a resilient sealing element which is continuously closed on itself may be arranged, which is resiliently compressible.

In some embodiments, at least two elastic sealing elements may be arranged between the first face of the respective step and the second face of the respective flange, said at least two elastic sealing elements being arranged concentrically to each other, the elastic sealing element lying on the outside correspondingly surrounding the elastic sealing element lying on the inside. By providing at least two elastic sealing elements, a multiple sealing structure can be formed between the first face of the corresponding step portion and the second face of the corresponding flange, thereby increasing redundancy of the sealing structure and ensuring sealing reliability.

In some embodiments, at least one recess for receiving the resilient sealing element may be configured in the first face of the respective step. In the case of the provision of the recess, an accurate positioning of the elastic sealing element can be achieved.

In some embodiments, the resilient sealing element may be received in the recess and in the undeformed state the resilient sealing element may protrude beyond the recess.

In some embodiments, the volume of the resilient sealing element in the deformed state of compression may be smaller than the volume of the recess. When the height of the respective elastic sealing element in the undeformed state is greater than the depth of the respective recess and the volume in the deformed state is smaller than the volume of the respective recess, a tight fit can be produced between the first face of the respective step and the second face of the respective flange in the region outside the recess, whereby the sealing performance is further improved. In addition, in the case of designing the depth distance between the first surface and the inner surface of the housing, the compression amount of the elastic sealing element can be omitted, so that the depth distance design difficulty is simplified.

In some embodiments, a first raised seal may be configured between the first face of the respective step and the resilient seal element, the first raised seal being formed by a rigid step raised bead raised on the first face of the respective step or by a first resilient seal element raised bead on the resilient seal element in contact with the first face of the respective step. Therefore, interference fit can be realized between the first surface of the corresponding step part and the elastic sealing element, so that stable and good sealing effect is realized.

In some embodiments, a second raised seal may be configured between the second face of the respective flange and the resilient sealing element, the second raised seal being formed by a second resilient sealing element raised bead on the resilient sealing element that contacts the second face of the respective flange. Thereby, an interference fit can be achieved between the second face of the respective flange and the resilient sealing element, whereby a stable and good sealing effect is achieved.

In some embodiments, a fastening member may be provided by which the connector can be fixedly connected with the housing so as to generate a pressing force for sealing-engaging the elastic sealing element with the stepped portion and the flange.

In some embodiments, the depth spacing of the first face of the corresponding step for the connector from the inner face of the housing may be determined based on the thickness of the resilient sealing element after compression under the influence of the compression force.

In some embodiments, the connector may be configured as a GPIO connector or a USB connector.

In some embodiments, the connector may have a screw cap that is associated with the externally disposed end, by means of which the externally disposed end of the connector can be sealed off in a sealing manner when not in use. Thus, the exposed end of the connector can be sealed off by screwing the cap when not in use, so as to be protected from adverse weather effects.

In some embodiments, the cross-section of the stepped portion with the smaller diameter for the through-hole of the connector is configured as a truncated circle to mate with a corresponding mating structure of the connector. Thereby, a so-called "fool-proof" design can be achieved, thereby simplifying the difficulty of installation when installing the connector in the housing through hole.

In some embodiments, one of the at least two through-parts is configured as a key for externally actuating an internal component of the environmental monitoring device, the key having an elastically deformable waterproof cap on which a flange of the key is integrally formed. The waterproof cap may be composed of an elastomer, for example, rubber.

In some embodiments, the flange of the waterproof cap of the key is adhered to the first face of the corresponding step with the second face of the flange by a sealant.

In some embodiments, the fastening member includes a threaded connection.

In some embodiments, the resilient sealing element is comprised of silicone or EPDM.

As shown in fig. 1 and 2, in this embodiment, an arrangement for an environmental monitoring device according to the present disclosure includes: a waterproof housing 1, a circuit board 2 provided inside the housing 1, two connectors 31 for connecting an internal member of the environment monitoring apparatus with an external member, and one key 32 for manipulating the internal member of the environment monitoring apparatus from the outside. The two connectors 31 may be a GPIO connector 311 and a USB connector 312, wherein the circuit board 2 can be coupled to the solar panel 5 (see fig. 5) provided outside via the GPIO connector 311, and the USB connector 312 can be used for coupling with other external components. The connector 31 and the key 32 are configured here as a pass-through part 3. Through holes 11 for the respective through-members 3 are provided in the housing 1, respectively. As is clear from fig. 2, these through-parts 3 pass through corresponding through-holes 11 of the housing 1, which are associated with the respective through-parts 3. The respective one ends of these through parts 3 are coupled to the circuit board 2. The respective other ends of these through parts 3 protrude outside the housing 1. In the embodiment shown in fig. 1 and 2, two connectors 31 and a key 32 are provided as the through-part 3. In some other embodiments, other numbers or types of pass-through members 3 may be provided. For example, two connectors 31 or one connector 31 and one key 32 or three or more through members 3 may be provided.

As shown in fig. 2 and fig. 5a and 5b, each through hole 11 has a corresponding step 12. The respective through-part 3, i.e. the respective connector 31 and the key 32, has a corresponding collar 33 on the circumferential surface. The flange of the GPIO connector 311 and the flange of the USB connector 312 may be provided at the middle section of the peripheral surface as in the usual connector 31. The flange of the key 32 may be provided at an end section of the peripheral surface. The key 32 may have an elastically deformable waterproof cap 321 composed of an elastic body, and a flange of the key 32 is integrally formed on the waterproof cap 321, for example, at an end section of a peripheral surface of the waterproof cap 321 as shown in fig. 2. The lateral dimensions of the through holes 11 match the lateral dimensions of the respective pass-through members 3. In particular, the lateral dimensions of the step 12 of each through hole 11 match the lateral dimensions of the flange 33 of each through part 3.

The flange 33 of the through-part 3 can be arranged, for example, against a corresponding step 12 of the associated through-hole 11. A sealing structure can be formed between the first face 121 of the corresponding step 12 facing the interior of the housing 1 and the second face 331 of the corresponding flange 33 facing the exterior of the housing 1. For the connector 31, this sealing structure may be achieved by the elastic sealing element 4 being arranged between the first face 121 of the respective step 12 and the second face 331 of the respective flange 33. The elastic sealing element 4 can be closed continuously on itself, i.e. can be designed as a sealing ring or sealing ring. For fixedly connecting the connector 31 with the housing 1, fastening members 313, such as bolt-nut screw connection members, may be provided. The tightening member 313 can generate a pressing force that causes the elastic sealing element 4 to sealingly engage with the stepped portion 12 and the flange 33. For the key 32, the flange 33 of the waterproof cap 321 of the key 32 may be adhered with its second face 331 to the first face 121 of the corresponding step 12 by a sealant.

As shown in fig. 2, in this embodiment, each of the first faces 121, in particular, the region of the first face 121 for providing the corresponding flange 33, is respectively designed to be spaced apart from the depth of the inner side 13 of the case 1 such that, in the assembled state, the amounts of projection of the GPIO connector 311, the USB connector 312, and the key 32 from the inner side 13 of the case 1 are identical, so that the portions of the GPIO connector 311, the USB connector 312, and the key 32 coupled to the circuit board 2 are flush with each other. Thereby, the circuit board 2 can be placed flat on the GPIO connector 311, the USB connector 312, and the keys 32. In some embodiments, for different types of connectors 31 and keys 32, the depth spacing of the first faces 121 from the inner face 13 of the housing 1 may be designed according to the structure of the connectors 31 and keys 32 and, if necessary, according to the thickness of the sealing structure, in particular the thickness after compression. The depth distance of the first faces 121 from the inner face 13 of the housing 1 can also be seen well in fig. 5 a.

Furthermore, as is clear from fig. 2, in the case where the flange 33 of the connector 31 is provided at the corresponding step 12 of the associated through hole 11, as described above, the sealing structure may be realized by the self-continuously closed elastic sealing element 4 arranged between the first face 121 of the corresponding step 12 and the second face 331 of the corresponding flange 33, which elastic sealing element 4 is elastically compressible. In the embodiment shown in fig. 2, one elastic sealing element 4 is arranged between the first face 121 of the respective step 12 and the second face 331 of the respective flange 33. In other embodiments, at least two elastic sealing elements 4 can also be arranged between the first face 121 of the respective step 12 and the second face 331 of the respective flange 33, said at least two elastic sealing elements 4 being arranged concentrically to each other, the elastic sealing element 4 lying on the outside correspondingly surrounding the elastic sealing element 4 lying on the inside. Multiple seals may thereby be provided between the first face 121 of the respective step 12 and the second face 331 of the respective flange 33, respectively.

In the embodiment shown in fig. 2, the first face 121 of the step 12, the second face 331 of the flange 33 of the connector 31 and the surfaces of the elastic sealing element 4 with the first face 121 and the second face 331 are each configured flat. In other embodiments, as shown in fig. 3, a recess 122 for receiving the resilient sealing element 4 may be configured in the first face 121 of the respective step 12. In this embodiment, one recess 122 is provided. In other embodiments, a plurality of recesses 122 may be provided depending on the number of elastic sealing elements 4. The elastic sealing element 4 is accommodated in said recess 122 and the elastic sealing element 4 protrudes beyond said recess 122 in the undeformed state. Thereby, when pressed, the elastic sealing element 4 may be in contact with the second face 331 of the flange 33 of the connector 31 and the surface of the recess 122, thereby achieving a sealing effect. The volume of the elastic sealing element 4 in the deformed state is smaller than the volume of the recess 122. At this time, a close fit may be generated between the first face 121 of the corresponding stepped portion 12 and the second face 331 of the corresponding flange 33 in the region other than the recessed portion 122, thereby further improving the sealing performance. In addition, in designing the depth spacing between the first face 121 and the inner face 13 of the housing 1, the compression amount of the elastic sealing element 4 may be omitted, thereby simplifying the design difficulty of the depth spacing.

In addition or alternatively to the embodiment of fig. 3, in the embodiment shown in fig. 4a and 4b, a first raised seal may be configured between the first face 121 of the respective step 12 and the resilient sealing element 4, wherein the first raised seal may be formed by a rigid step raised bead 41 raised on the first face 121 of the respective step 12, as shown in fig. 4a, or by a first resilient sealing element raised bead 42 on the resilient sealing element 4 in contact with the first face 121 of the respective step 12, as shown in fig. 4 b. Furthermore, a second raised seal may be formed between the second face 331 of the respective flange 33 and the resilient sealing element 4. As shown in fig. 4b, the second raised sealing portion is formed by a second resilient sealing element raised bead 43 on the resilient sealing element 4 in contact with the second face 331 of the corresponding flange 33. Since the second raised sealing portion is formed by the second resilient sealing element raised bead 43, which results in the second resilient sealing element raised bead being flattened in the compressed state, the second raised sealing portion is not clearly visible in the compressed state as shown in fig. 4 a. In the embodiment shown in fig. 4a and 4b, one first raised sealing portion and one second raised sealing portion are provided. In other embodiments, a plurality of first raised seals and/or second raised seals may also be provided. The first and second boss seals are subjected to a pressing force generated by the fastening member 313 when the connector 31 and the housing 1 are fixedly connected by the fastening member 313 and thus an interference fit occurs between the elastic sealing element 4 and the flange 33 and the stepped portion 12 of the connector 31. The interference fit may be an interference caused by the elastic sealing element 4 being pressed by the rigid step portion protruding rib 41 of the step portion 12, or an interference caused by the corresponding elastic sealing element protruding rib on the elastic sealing element 4 being flattened by the flange 33 of the connector 31 and the step portion 12.

The structure of the through holes 11 of the housing 1 and the stepped portions 12 thereof can be clearly seen in fig. 5a and 5 b. As shown in fig. 5a, the depth distance between the first surface 121 of each step 12 and the inner surface 13 of the housing 1 is designed differently depending on the structure of the associated connector 31 or key 32 and the dimensions of the corresponding sealing structure. As shown in fig. 5b, the cross section of the stepped portion 12 with the smaller diameter section of the through hole 11 for the connector 31 may be configured as a truncated circle to mate with a corresponding mating structure of the connector 31. The truncated circular portion is provided with a projection 14 projecting from the cylindrical inner wall. The shape of the truncated circular portion matches the truncated circular profile at the connector 31. Thereby, a "fool-proof" design with respect to the mounting of the connector 31 in the through hole 11 can be achieved.

In addition to the above-described sealing structure, in order to achieve waterproofing, the connector 31 may have a screw cap 314 fitted to an end portion provided outside, and the end portion provided outside of the connector 31 may be sealed off hermetically by the screw cap 314 when not in use. The screw cap 314 can be arranged on the connector 31 in a loss-proof manner. The screw cap 314 may be coupled to the outer end of the connector 31 by a screw structure. The screw cap 314 may be constructed of plastic or rubber.
