Description

Technical Field

[0001] The utility model relates to the technical field of meter data collectors, in particular to a data collector housing and a data collector. Background Art

[0002] Data collectors are devices used to collect and record data. They are usually used in combination with various instruments, such as various meters. When the working environment of the instruments is relatively harsh, higher requirements are placed on the waterproof and dustproof sealing performance of the data collector.

[0003] Currently, the data logger housing with high dust and water resistance on the market mainly adopts two forms: mechanical seal and glue seal to achieve sealing effect, but the sealing protection reliability of high sealing performance products based on these two types of sealing methods is low and cannot be soaked in water for a long time. The mechanical sealing structure is prone to sealing failure due to tolerance or deformation, temperature change and other reasons during use, while the conventional glue seal is prone to gaps at the junction of the colloid and the shell, resulting in sealing failure. In addition, this traditional glue filling process is cumbersome and inefficient, which greatly affects the efficiency of the entire production line.

[0004] Therefore, the prior art needs to be further developed. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a data collector housing and a data collector using the housing. The housing adopts a unique and simple glue injection exhaust structure, which greatly improves the sealing level of the collector.

[0006] In view of the above problems, the utility model provides the following technical solutions:

[0007] In the first aspect, the present application provides a data acquisition device shell, which is assembled from an upper shell and a lower shell, and at least two glue injection exhaust structures are arranged on the upper shell, and the glue injection exhaust structure includes: a bottom plate integrally arranged with the upper shell mainboard, glue injection exhaust holes penetrating the bottom plate, and at least one layer of wall structure arranged on the top surface of the bottom plate around the periphery of the glue injection exhaust structure, the height of the wall structure is higher than the height of the glue injection exhaust structure, and the upper shell and the lower shell cover each other to form an inner cavity for installing electronic components and filling sealant.

[0008] Optionally, in the data acquisition device housing, the multi-layer wall structure is a concentric annular structure centered on the glue injection exhaust structure.

[0009] Optionally, in the data acquisition device shell, a limit baffle is further provided on the top surface of the upper shell, and both ends of the limit baffle extend to the outer flange of the upper shell respectively, and the limit baffle and the connected outer flange of the upper shell surround the wall structure.

[0010] Optionally, in the data acquisition device housing, the heights of the limit baffle and the outer flange of the upper housing are both higher than the height of the outermost wall structure.

[0011] Optionally, in the data collector housing, the number of the wall structure is not less than one layer, and the height of the center wall is lower than the height of the outer walls.

[0012] Optionally, in the data acquisition device housing, the number of the wall structures is not less than two layers, and the height of the wall structures gradually increases from the inside to the outside with the glue injection exhaust structure as the center.

[0013] Optionally, in the data acquisition device housing, the bottom surface of the bottom plate around the glue injection exhaust hole is recessed inward to form a groove.

[0014] Optionally, in the data acquisition device shell, an electronic component installation cavity is provided on the lower surface of a partial area of ​​the upper shell, and the electronic component installation cavity is formed by the upward depression and / or downward extension of the wall surface of the upper shell, and the bottom surface of the electronic component is set to be slightly higher than the upper surface of the circuit board; the electronic component is an LED lamp, a liquid crystal display or a built-in antenna.

[0015] Optionally, in the data acquisition device shell, the upper shell and the lower shell are snap-connected, and the side wall of the upper shell includes a snap-connecting portion that is plugged into the inner wall of the lower shell and a protrusion that extends horizontally outward along the outer wall and is supported by the top of the side wall of the lower shell; the top surface of the side wall of the lower shell is higher than the horizontal inner wall of the upper shell.

[0017] The data collector housing and the data collector provided by the utility model have the following beneficial effects:

[0018] 1. The data collector shell adopts a unique glue injection exhaust structure, which is simple and ingenious. The multi-layer wall structure outside the glue injection exhaust hole not only greatly expands the bonding surface between the sealant and the shell, but also extends the path for moisture in the air to enter the glue injection exhaust hole from the outside. A multi-layer wall barrier is set for this path. External water vapor can only enter the glue injection exhaust hole under the action of a large siphon force, which can effectively isolate external water vapor and improve the sealing protection reliability of the data collector. A groove is set inside the glue injection exhaust hole, which is conducive to the complete discharge of gas inside the shell and effectively avoids air entrapment.

[0019] 2. The structural improvement of the glue injection exhaust structure not only greatly improves the waterproof and dustproof sealing level of the data collector, but also enables the applied data collector to be reliably sealed even when immersed in water for more than 30 days under temperature changes. Its protection level reaches the IPX8-III of the group standard T / CMA SB 058-2021, which is much higher than the IPX8-I level of the existing products that meet this standard. In addition, it also improves the convenience of the glue injection process of the data collector, realizes the solution of glue injection of the whole machine after the assembly of each component, and improves the efficiency of glue injection and assembly.

The term "and / or" used in this specification includes any and all combinations of one or more related listed items. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Example 1

[0031] like Figures 1 to 5 As shown, in this embodiment, a data acquisition device housing is provided, which is assembled from an upper housing 51 and a lower housing 52. At least two glue injection exhaust structures Z1 are provided on the upper housing (i.e., the upper cover). At least one glue injection exhaust structure Z1 is used to inject sealant into the inner cavity of the housing, and at least one glue injection exhaust structure Z1 serves as a gas exhaust port for the inner cavity of the housing during the glue injection process. The high-reliability sealing protection function of the data acquisition device housing is achieved through the mutual cooperation of the two functional glue injection exhaust structures.

[0032] Specifically, Figure 5 As shown, the glue injection exhaust structure Z1 includes: a bottom plate Z11 integrally arranged with the upper shell mainboard, a glue injection exhaust hole Z12 penetrating the bottom plate, and at least one layer of wall structure Z13 arranged on the top surface of the bottom plate around the periphery of the glue injection exhaust structure, the height of the wall structure is higher than the height of the glue injection exhaust structure, and the upper shell and the lower shell cover each other to form an inner cavity for installing electronic components and filling sealant.

[0033] Optionally, the number of the wall structure is not less than one layer, and the height of the central wall is lower than the height of the outer walls.

[0034] The setting of the above-mentioned wall structure significantly expands the contact surface between the sealant of the injection vent hole and the shell, expands the bonding surface between the sealant and the shell, and effectively prevents the separation between the two; in addition, the setting of the wall structure prolongs the path of moisture in the air from the outside to the injection vent hole, and requires a large siphon force to enter the injection vent hole. External water vapor needs to "climb over" multiple walls, which can effectively isolate external water vapor and improve the sealing protection reliability of the structure.

[0035] Therefore, the above-mentioned wall structure greatly improves the sealing performance of the glue injection exhaust hole, so that the applied data collector can still be reliably sealed even when immersed in water for more than 30 days under temperature changes.

[0036] On the basis of the above, it is further preferred that the top surface height of the glue injection vent hole Z12 is higher than the upper surface of the bottom plate. This arrangement enables the top of the side wall of the glue injection vent hole to form a wall-like structure, further improving the sealing effect.

[0037] In other embodiments, the number of layers of the wall structure is 2, 3 or more, and the height of the innermost wall is lower than the height of the outermost wall.

[0038] On this basis, one situation is that the second and third layers of walls from the inside to the outside are of similar height, both lower than the outermost limit baffles and outer flanges, and both higher than the innermost ones.

[0039] Another more preferred configuration is as follows: the height of the wall structure gradually increases from the inside to the outside with the glue injection and exhaust hole as the center.

[0040] The higher the height of the wall, the more beneficial it is for protection. The setting of the external wall structure higher than the internal wall structure means that the moisture in the air can only contact the outermost and highest wall structure first, and the internal wall structure is completely immersed in the sealant, so that the external moisture must "climb over" multiple wall structures step by step from the external wall to the inside before entering the glue filling port. The more layers of the wall structure, the more obstacles there are for moisture in the air to enter the glue filling hole, the more difficult it is for the potting glue to separate from the contacting shell part, and the better the sealing performance of the glue filling port structure.

[0041] In this embodiment, the multi-layer wall structure is a concentric annular structure with the glue injection and exhaust structure as the center.

[0042] Furthermore, a limit baffle Z15 is provided on the top surface of the upper shell 51, and both ends of the limit baffle extend to the outer flange 511 of the upper shell respectively. The limit baffle and the connected outer flange of the upper shell surround the wall structure.

[0043] The height of the limit baffle 15 and the outer flange 511 of the upper shell are higher than the height of the outermost wall structure. The limit baffle and the connected outer flange also form an outer wall around the injection exhaust structure Z1, making full use of the structural characteristics and space of the upper shell to further improve the sealing effect.

[0044] During the glue filling process of the data collector shell, if the air in the shell is not discharged from the glue injection vent in time, some bubbles will gather on the bottom surface of the upper shell. Due to the error of the existing manufacturing process, the bottom surface of the upper shell will be uneven, which is not conducive to the exhaust of bubbles, resulting in the accumulation of some bubbles on the bottom surface of the upper shell of the data collector.

[0045] In view of the above problems, the following improvements are made: the bottom surface of the bottom plate Z11 around the injection and exhaust holes Z12 is inwardly recessed to form a groove Z14. With this arrangement, the unexhausted air in the collector housing will gather below the injection and exhaust holes, which is conducive to the complete exhaust of the gas inside the housing and effectively avoids the phenomenon of trapped air.

[0046] In order to solve the problem that the electronic components in the inner cavity of the shell are wrapped by the sealant and affected during the overall glue pouring process, an electronic component installation cavity 512 is provided on the lower surface of a partial area of ​​the upper shell. The electronic component installation cavity 512 is formed by the upward depression and / or downward extension of the wall surface of the upper shell. The bottom surface position of the electronic component is set to be slightly higher than the upper surface of the circuit board. The electronic component is an LED lamp, a liquid crystal display or a built-in antenna, etc.

[0047] In this embodiment, Figure 3 and 4 As shown, the electronic component is an LED lamp 53, and the upper part of the electronic component installation cavity 512 is formed by the wall surface of the upper shell being recessed upward, and the side wall of the installation cavity extends downward to form the lower part of the cavity; optionally, the top surface of the electronic component is transparent.

[0048] After such setting, after the collector is assembled, the bottom surface of the side wall of the LED lamp installation cavity is slightly higher than the upper surface of the circuit board, and there is a gap between the two. This setting allows part of the gas to be enclosed in the LED lamp installation cavity during glue filling, which can effectively prevent the main part of the LED lamp from being immersed in the sealant, thereby ensuring the normal operation of the LED lamp and meeting the requirements of the working environment of the LED lamp. The settings of other electronic components are similar and will not be repeated.

[0049] Optionally, the upper shell and the lower shell of the data acquisition device are snap-connected, and the side wall of the upper shell includes a snap-connecting portion 513 inserted into the inner wall of the lower shell and a protrusion 514 extending horizontally outward along the outer wall and supported by the top 521 of the side wall of the lower shell; the top surface of the side wall of the lower shell is higher than the horizontal inner wall of the upper shell.

[0050] In essence, the above arrangement makes the horizontal inner wall of the upper shell lower than the horizontal surface of the lower shell for engaging with the upper shell. This arrangement not only avoids the overflow of the colloid in the shell, but also improves the sealing reliability of the joint between the upper shell and the lower shell.

[0051] In order to improve the connection stability of the upper and lower shells, the upper shell and the lower shell are also fixedly connected by other buckle structures and plug-in structures. Figure 6 As shown, the buckle structure includes a second buckle slot 515a and a buckle protrusion 515b respectively arranged on the upper and lower shells and buckled with each other. In addition, the corresponding action surfaces of the upper shell and the lower shell can also be correspondingly provided with plug blocks and plug holes that are plugged in and matched with each other.

[0052] Second, as Figure 5 and 6 As shown, this embodiment also provides a data collector, which includes the above-mentioned data collector housing, wherein a circuit board 54 and a battery 55 are installed in the lower housing 52 and filled with sealant; the circuit board is installed near the upper housing 51.

[0053] The bottom surface of the side wall of the LED lamp installation cavity is slightly higher than the upper surface of the circuit board. This arrangement allows part of the gas to be enclosed in the LED lamp installation cavity during glue pouring, preventing the upper part of the LED lamp from being immersed in the sealant and affecting normal operation, thereby meeting the working requirements of the LED lamp.

[0054] The cavity enclosed by the upper shell and the lower shell is filled with sealant to improve the waterproof sealing performance of the inner cavity of the collector.

[0055] In this embodiment, a threading hole is provided on the bottom surface of the lower box body, and a sealing member 522 for the threading of the wire is installed on the threading hole.

[0056] In addition, unlike the traditional inverted glue pouring and colloid complete drying post-processing process, in the scheme of this embodiment, the data acquisition shell can be assembled first, and then the colloid can be poured into the inner cavity through the glue injection vent hole. After 4 to 5 hours, the colloid in the box does not flow and can be returned to the production line for subsequent processing or assembly of other structures. Therefore, compared with the existing glue pouring process, the data acquisition design of this application greatly optimizes the production process and significantly improves production efficiency.

[0057] Therefore, the setting of the glue injection and exhaust structure of the above-mentioned data collector not only improves the sealing performance, but also improves the work efficiency of the data collector assembly and glue filling process, and can realize the glue filling operation after the whole machine assembly is completed, effectively solving the bottleneck problem of low efficiency and long cycle caused by the long transportation and drying time of the glue filling process in the existing production process, the production process is optimized, and the production efficiency is improved.

[0058] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated. It is understood that, for those skilled in the art, equivalent replacements or changes can be made according to the technical solution and concept of the utility model, and all such changes or replacements shall fall within the scope of protection of the claims attached to the utility model.
