Technical Field

[0001] The utility model relates to the technical field of telemetry terminals, and in particular to a telemetry terminal with good sealing performance. Background Art

[0002] A telemetry terminal is a microprocessor-based control device. Its most notable feature is that it can remotely control on-site equipment and obtain equipment data. It is widely used in smart water services, smart water conservancy and other fields. Especially in extremely harsh environments, remote communication through telemetry terminals can save a lot of manpower costs.

[0003] Existing telemetry terminals have the following shortcomings: Telemetry terminals with low protection levels usually need to be configured in a protective box for use, but the protective boxes currently used have a simple structure and only have basic protection measures. They cannot protect against humid air or long-term rain immersion, so it is easy to cause damage to the equipment, leading to unnecessary losses. Utility Model Content

[0004] The utility model provides a telemetry terminal with good sealing performance, which solves the problem of poor sealing effect of the telemetry terminal in the related art.

[0005] The technical solution of the utility model is as follows:

[0006] A telemetry terminal with good sealing performance, comprising:

[0007] A bottom shell having a first installation space and a second installation space;

[0008] a battery compartment, disposed in the first installation space;

[0009] A circuit board is arranged in the second installation space, and the first installation space and the second installation space are used for glue filling and sealing;

[0010] A cover plate is arranged in the second installation space, and the cover plate is used to enhance the strength of the glue pouring.

[0011] Optionally, it also includes:

[0012] An upper cover is provided on the bottom shell, and is used to seal the first installation space and the second installation space after glue filling. The cover plate is located between the circuit board and the upper cover.

[0013] Optionally, the second installation space has a plurality of first reinforcing ribs, the first reinforcing ribs abut against the cover plate, the cover plate has a plurality of protrusions around it, and the protrusions abut against the bottom shell;

[0015] Optionally, the cover plate has glue injection holes and air guide holes.

[0016] Optionally, the cover plate is a frustum structure, and the lower end surface of the cover plate decreases from the center to the surrounding areas.

[0017] Optionally, the lower end surface of the cover plate and the bottom shell form a first glue pouring area, and the first glue pouring area is used to seal the circuit board.

[0018] Optionally, the upper end surface of the cover plate and the upper cover form a second glue pouring area, and the second glue pouring area is used to strengthen the structure.

[0019] Optionally, the first installation space is a third glue filling area, and the third glue filling area is used to seal the battery compartment.

[0020] Optionally, the upper end surface of the cover plate has a plurality of third reinforcing ribs, and the third reinforcing ribs are used to increase the glue filling area.

[0021] Optionally, the bottom shell has a plurality of gaps, and the gaps connect the first installation space and the second installation space.

[0022] The working principle and beneficial effects of the utility model are as follows:

[0023] In the present invention, the interior of the bottom shell is divided into a first installation space and a second installation space, with the battery compartment installed in the first installation space. The battery compartment can be removable to facilitate battery replacement and maintenance. The circuit board is installed in the second installation space and secured to the bottom shell by screws or clips. The potting compound has excellent insulation, corrosion resistance, and sealing properties. After potting, the telemetry terminal is placed in an environment with appropriate temperature and humidity for curing, allowing the adhesive to fully solidify and form a solid sealing layer.

[0024] By providing first and second mounting spaces within the bottom shell and sealing them with glue, moisture, dust, and other impurities are effectively prevented from entering the telemetry terminal, improving its sealing performance and ensuring stable operation in harsh environments. This glue sealing provides excellent protection for the battery compartment and circuit board from external forces such as impact, vibration, and electromagnetic interference, extending the service life of the telemetry terminal. The potting glue has excellent insulating properties, effectively preventing leakage and short circuits between the battery compartment and circuit board, improving the waterproof rating and service life.

[0025] After installing the circuit board in the second mounting space, place the cover plate on top of it. A gap exists between the cover plate and the circuit board for glue pouring. Fasteners, such as screws and clips, can be used to secure the cover plate in the second mounting space to prevent movement during the glue pouring process. Before installing the cover plate, partially pour glue into the second mounting space. Once the glue reaches the desired level, install the cover plate and slowly inject the potting compound into the first and second mounting spaces, ensuring that every corner is fully filled. During the glue pouring process, the glue comes into contact with the cover plate, forming a uniform layer on its surface. The presence of the cover plate restricts the flow of the glue, thereby increasing the strength and stability of the glue pouring process.

[0026] The cover plate increases the strength and stability of the glue pouring process. During the pouring process, the glue will tightly bond with the cover plate, forming a solid whole. The cover plate can withstand a certain amount of pressure and impact, thus protecting the circuit board from damage.

[0027] The tight fit between the cover and the circuit board further enhances sealing performance. The adhesive, acting on the cover, effectively fills the gap between the circuit board and the upper cover, preventing moisture, dust, and other impurities from entering the secondary mounting space. This helps improve the telemetry terminal's protection level and extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0037] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0038] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] Reference Figures 1 to 6 , which is the first embodiment of the utility model, proposes a telemetry terminal with good sealing performance, including: a bottom shell 1, having a first installation space 11 and a second installation space 12; a battery compartment 2, arranged in the first installation space 11; a circuit board 3, arranged in the second installation space 12, the first installation space 11 and the second installation space 12 are used for glue sealing; a cover plate 5, arranged in the second installation space 12, the cover plate 5 is used to enhance the strength of the glue.

[0040] In this embodiment, the interior of the bottom case 1 is divided into a first installation space 11 and a second installation space 12, and the battery compartment 2 is installed in the first installation space 11. The battery compartment 2 can be designed to be removable to facilitate battery replacement and maintenance. The circuit board 3 is installed in the second installation space 12 and fixed to the bottom case 1 by screws or clips. The potting compound has excellent insulation, corrosion resistance, and sealing properties. After the potting is completed, the telemetry terminal is placed in an environment with appropriate temperature and humidity for curing, so that the glue can fully solidify and form a solid sealing layer.

[0041] By providing a first mounting space 11 and a second mounting space 12 within the bottom housing 1 and sealing them with glue, moisture, dust, and other impurities can be effectively prevented from entering the telemetry terminal, improving the terminal's sealing performance and ensuring stable operation in harsh environments. This glue sealing provides excellent protection for the battery compartment 2 and circuit board 3, preventing them from being affected by external forces such as impact, vibration, and electromagnetic interference, thereby extending the service life of the telemetry terminal. The potting glue has excellent insulating properties, effectively preventing leakage and short circuits between the battery compartment 2 and circuit board 3, improving the waterproof rating and service life.

[0042] After the circuit board 3 is installed in the second installation space 12, the cover plate 5 is placed above the circuit board 3. There is a certain gap 114 between the cover plate 5 and the circuit board 3 for glue pouring. Some fixing parts, such as screws, clips, etc., can be used to fix the cover plate 5 in the second installation space 12 to prevent the cover plate 5 from moving during the glue pouring process. Before installing the cover plate 5, some glue can be poured into the second installation space 12. After the glue reaches the appropriate height, install the cover plate 5 and slowly inject the potting glue into the first installation space 11 and the second installation space 12 to ensure that the glue fully fills every corner. During the glue pouring process, the glue will come into contact with the cover plate 5 and form a uniform glue layer on its surface. Due to the presence of the cover plate 5, the flow of the glue is subject to a certain restriction, which can increase the strength and stability of the glue pouring.

[0043] The provision of the cover plate 5 can increase the strength and stability of the glue pouring process. During the glue pouring process, the glue will be tightly combined with the cover plate 5 to form a solid whole. The cover plate 5 can withstand a certain amount of pressure and impact, thereby protecting the circuit board 3 from damage.

[0044] The tight fit between the cover plate 5 and the circuit board 3 further enhances the sealing performance. The adhesive, acting on the cover plate 5, can better fill the gap 114 between the circuit board 3 and the upper cover 4, preventing moisture, dust, and other impurities from entering the second installation space 12. This helps to improve the protection level of the telemetry terminal and extend its service life.

[0045] Furthermore, it also includes: an upper cover 4, which is arranged on the bottom shell 1, and is used to seal the first installation space 11 and the second installation space 12 after glue filling, and the cover plate 5 is located between the circuit board 3 and the upper cover 4.

[0046] In this embodiment, the shape and size of the upper cover 4 should be closely matched with the bottom shell 1 to achieve a good sealing effect. A sealing structure, such as a sealing strip, a sealing gasket, etc., is provided on the upper cover 4 to further enhance the sealing performance. The material of the sealing structure should have good elasticity and corrosion resistance, and be able to maintain the sealing effect under different environmental conditions. After the first installation space 11 and the second installation space 12 in the bottom shell 1 are filled with glue, the upper cover 4 is placed on the bottom shell 1. The upper cover 4 is firmly connected to the bottom shell 1 by screws, snaps or other fixing methods. During the installation of the upper cover 4, it is necessary to ensure that the sealing structure is in full contact with the bottom shell 1, without gaps 114 and looseness. Appropriate tools can be used for tightening to ensure the reliability of the seal.

[0047] The setting of the upper cover 4 provides additional sealing protection for the first installation space 11 and the second installation space 12 after glue filling. Combined with the glue filling seal, it forms a double sealing protection, which greatly improves the sealing performance of the telemetry terminal. Even in extreme environments, it can effectively prevent moisture, dust and other harmful substances from entering the interior of the terminal, protecting key components such as the battery compartment 2 and the circuit board 3. The close combination of the upper cover 4 and the bottom shell 1 increases the overall structural stability of the telemetry terminal. When subjected to external impact, vibration or other mechanical stress, it can better protect the internal components and reduce the risk of damage. At the same time, the upper cover 4 can also play a certain protective role to prevent damage to the terminal caused by accidental collisions.

[0048] Furthermore, the second installation space 12 has several first reinforcing ribs 121, which abut against the cover plate 5. The cover plate 5 has several protrusions 51 around it, and the protrusions 51 abut against the bottom shell 1; the first installation space 11 has a second reinforcing rib 111, and the battery compartment 2 abuts against the second reinforcing rib 111.

[0049] In this embodiment, several first reinforcing ribs 121 are designed within the second installation space 12 of the bottom shell 1. These ribs can take the form of strips of protrusions 51, evenly distributed along the inner wall of the second installation space 12. The first reinforcing ribs 121 can be manufactured integrally with the bottom shell 1 through a mold, ensuring a secure connection. Several protrusions 51 are designed around the perimeter of the cover plate 5. These protrusions 51 are staggered with the first reinforcing ribs 121 within the second installation space 12, forming a labyrinthine structure that enhances the strength of the glue injection process and ensures that the cover plate 5 is securely installed and prevents movement during the glue injection process.

[0050] The first reinforcing ribs 121 within the second mounting space 12 and the protrusions 51 surrounding the cover plate 5 significantly enhance the structural strength of the second mounting space 12, allowing it to withstand greater external impact and pressure, thereby improving the reliability and stability of the device. The protrusions 51 and first reinforcing ribs 121 restrict movement of the cover plate 5 during the glue pouring process, ensuring uniform and stable glue pouring. During glue pouring, the glue is able to better fill the space between the circuit board 3 and the cover plate 5, improving the strength and sealing of the glue pouring. The protrusions 51 and first reinforcing ribs 121 form a labyrinthine structure, enhancing the glue pouring effect.

[0051] In the first installation space 11 of the bottom shell 1, several second reinforcing ribs 111 are designed. The second reinforcing ribs 111 can be manufactured together with the bottom shell 1 by means of integral mold molding to ensure the firmness of the connection. The battery compartment 2 can be smoothly installed in the first installation space 11. When the battery compartment 2 is installed in the first installation space 11, the outer wall of the battery compartment 2 is tightly abutted against the second reinforcing ribs 111 in the first installation space 11. During the installation process, a certain amount of pressure can be appropriately applied to ensure that the battery compartment 2 is in full contact with the second reinforcing ribs 111, thereby improving the stability of the structure. The second reinforcing ribs 111 in the first installation space 11 abut against the battery compartment 2, providing additional support and fixation for the battery compartment 2. This greatly enhances the structural strength of the bottom shell 1 at the first installation space 11, and can effectively resist the impact and extrusion of external forces.

[0052] Furthermore, the cover plate 5 has a glue injection hole 52 and an air guide hole 53 .

[0053] In this embodiment, glue injection holes 52 are provided on the side of the cover plate 5. The number and size of the glue injection holes 52 are designed according to actual needs. The glue injection holes 52 can be circular, square, or other shapes. An air guide hole 53 is provided in the center of the cover plate 5. The air guide hole 53 is used to expel bubbles during the glue injection process and ensure glue quality.

[0054] During the glue pouring process, slowly inject the potting glue into the second installation space 12 through the glue pouring hole 52 of the cover plate 5. The pouring speed should be moderate to avoid excessive bubbles due to excessive pouring. As the glue pouring progresses, the glue gradually fills the second installation space 12. During this process, bubbles generated are discharged through the air guide hole 53 in the center of the cover plate 5.

[0055] The design of the glue filling holes 52 and the air guide holes 53 on the cover plate 5 allows the bubbles generated during the glue filling process to be discharged smoothly. This effectively prevents bubbles from remaining in the glue and improves the quality and density of the glue filling. High-quality glue filling can provide better protection for the circuit board 3 and enhance the reliability and stability of the telemetry terminal. The presence of the air guide holes 53 facilitates exhaust during the glue filling process, allowing the glue to better fill the second installation space 12. At the same time, the exhaust process also helps to speed up the curing speed of the glue and improve production efficiency. After glue filling, a solid whole is formed between the cover plate 5 and the circuit board 3, which enhances the structural strength of the second installation space 12. This can effectively protect the circuit board 3 from external impact, vibration, electromagnetic interference and other factors, and extend the service life of the telemetry terminal.

[0056] Furthermore, the cover plate 5 is a frustum structure, and the lower end surface of the cover plate 5 decreases from the center to the surrounding areas.

[0057] In this embodiment, after the circuit board 3 is installed in the second installation space 12, the frustoconical cover plate 5 is placed above the circuit board 3. During the glue pouring operation, glue is slowly injected through the glue pouring hole 52 on the side of the cover plate 5. Because the lower end surface of the cover plate 5 is higher in the center and lower around the edges, forming a tapered, angled structure, bubbles or gas generated during the glue flow naturally flow upward along the tapered surface. During this upward flow, the bubbles and gas gradually converge and are ultimately discharged through the air guide hole 53 in the center of the cover plate 5.

[0058] The truncated cone structure of the cover plate 5 can effectively guide the bubbles and gases to flow upward, allowing them to be discharged smoothly through the air guide holes 53. This greatly improves the exhaust efficiency during the glue filling process, reduces the residual bubbles in the glue, and improves the glue filling quality. The truncated cone structure of the cover plate 5 fits more closely with the second installation space 12, which can effectively improve the sealing performance. It reduces the possibility of moisture, dust and other impurities entering the second installation space 12, protecting the circuit board 3 from the influence of the external environment. The truncated cone structure of the cover plate 5 has good mechanical properties and can withstand certain pressure and impact force. After glue filling, the cover plate 5 and the glue form a solid whole, which enhances the structural strength of the second installation space 12 and improves the telemetry terminal's ability to resist external forces.

[0059] Furthermore, the lower end surface of the cover plate 5 and the bottom shell 1 form a first glue potting area 54, which is used to seal the circuit board 3. The upper end surface of the cover plate 5 and the upper cover 4 form a second glue potting area 55, which is used to strengthen the structure. The first installation space 11 is a third glue potting area 112, which is used to seal the battery compartment 2.

[0060] In this embodiment, when preparing to perform the potting operation, the circuit board 3 is first accurately installed within the second mounting space 12 of the bottom case 1. The cover plate 5 is placed above the circuit board 3, forming a first potting area 54 between the lower end surface of the cover plate 5 and the bottom case 1. A suitable potting compound is selected and slowly injected into the first potting area 54 through the potting holes 52 on the side of the cover plate 5. During the potting process, ensure that the glue fully fills the gap 114 between the circuit board 3 and the bottom case 1, sealing these components within the first potting area 54. At the same time, pay attention to the venting of the air guide holes 53 to ensure that bubbles are smoothly discharged. Potting compound is injected into the second potting area 55 to enhance structural stability. The glue flows and solidifies within the second potting area 55, tightly bonding with the cover plate 5 and the upper cover 4, thereby enhancing the structural strength of the entire telemetry terminal. The battery compartment 2 is placed within the first mounting space 11 of the bottom case 1. Potting compound is then injected into the first mounting space 11 to form a third potting area 112. The glue seals the battery compartment 2 in the third glue filling area 112 to prevent moisture, dust and other impurities from entering the battery compartment 2, thereby protecting the safety and performance of the battery. The battery compartment 2 can also be glued separately.

[0061] By dividing the first glue potting area 54, the second glue potting area 55, and the third glue potting area 112, key components such as the circuit board 3 and the battery compartment 2 are sealed separately. This multiple sealing protection significantly improves the sealing performance of the telemetry terminal, enabling stable operation in harsh environments. The provision of the second glue potting area 55 strengthens the structural strength of the telemetry terminal. After the glue solidifies in the second glue potting area 55, it forms a solid whole with the cover plate 5 and the upper cover 4, capable of withstanding certain external forces and vibrations.

[0062] Furthermore, the upper end surface of the cover plate 5 has a plurality of third reinforcing ribs 56 , and the third reinforcing ribs 56 are used to increase the glue pouring area.

[0063] In this embodiment, the third reinforcing ribs 56 can be designed in the form of elongated strips, a grid, or other regular shapes. The presence of the third reinforcing ribs 56 increases the contact area between the cover plate 5 and the upper cover 4, thereby increasing the glue filling area. This allows the glue to better bond with the cover plate 5 and the upper cover 4, enhancing the stability of the structure.

[0064] The provision of the third reinforcing rib 56 significantly increases the glue filling area on the upper end surface of the cover plate 5. This allows the glue to flow and fill the second glue filling area 55 more fully, improving the density and uniformity of the glue filling. The increased glue filling area helps to enhance the structural strength of the telemetry terminal, improving the device's resistance to external forces and stability.

[0065] Furthermore, the bottom housing 1 has a plurality of gaps 114 , and the gaps 114 communicate with the first installation space 11 and the second installation space 12 .

[0066] In this embodiment, the bottom case 1 is provided with several gaps 114, connecting the first installation space 11 with the second installation space 12. During the glue filling operation, the glue is first injected into the first installation space 11 or the second installation space 12. The presence of gaps 114 allows the glue to flow between the two spaces. This ensures that the glue can fully fill all gaps around components such as the battery compartment 2 in the first installation space 11 and the circuit board 3 in the second installation space 12, achieving a better sealing effect.

[0067] The provision of gap 114 allows glue to flow between first mounting space 11 and second mounting space 12, thereby ensuring the sealing performance of the entire telemetry terminal. If any leakage occurs in either mounting space, the glue can be replenished through gap 114, forming a more complete sealing layer. After the glue is injected, it forms a connection in gap 114, increasing the overall structural strength of bottom case 1.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
