Description

Technical Field

[0001] The invention relates to the technical field of radio beacon positioning, in particular to an alarm tracker with a waterproof function. Background Art

[0002] An alarm tracker is a device that combines location tracking and security alarm technology, and is typically used for security monitoring of individuals, pets, or valuables. This type of tracker uses Beidou, GPS, GLONASS, or other positioning technologies to determine the location of the user or object, and sends the location data to the user's receiving device via mobile networks or satellite communications, thereby realizing functions such as alarms or early warnings.

[0003] In view of the usage requirements and applicable scope of the alarm tracker, in order to ensure the normal function of the alarm tracker, the alarm tracker should have a high usage intensity to ensure the service life of the alarm tracker. The most representative of these is the waterproof and sealing performance of the alarm tracker. At the same time, in order to improve the convenience of the alarm tracker, the overall volume of the alarm tracker is generally controlled to be small enough and compact in structure.

[0004] The premise of ensuring sealing is that the joints on the package need to fit well to a high degree. Therefore, when the joint gap is small, the filling rate of the sealing ring is indirectly increased, or more dark grooves are opened to avoid the sealing friction caused by the external pressure directly acting on the "O" ring. Whether it is the high degree of fit of the package or the opening of more dark grooves, the design of the sealing structure from the package body itself relies on high-precision processing technology, and the processing cost is not ideal. For this reason, we propose an alarm tracker with waterproof function. Summary of the invention

Figure 5 In the structural state shown, since the guide surface 1 is biased toward the geometric center of the cover, the sealing ring 2 is supported by both the sealing ring 1 and the guide surface 1. In the subsequent process of the sealing ring 2 being compressed and deformed, it is more conducive to better deformation guidance of the two petals thereon.

Beneficial Effects

[0037] Compared with the prior art, the present invention provides an alarm tracker with waterproof function, which has the following beneficial effects:

[0038] The alarm tracker with waterproof function has a shell and a cover, and the sealing ring 2 slides in different directions through the petals on it after being compressed, and further fills the gap between the two adjacent surfaces of the shell and the cover to form a double sealing layer. On the one hand, the waterproof performance of the alarm tracker can be significantly improved, and at the same time, it can better adapt to the slight tolerance changes of the shell and the cover.

[0039] Moreover, the two petals are in a bent state after deformation, and the van der Waals force inside them changes, resulting in an increase in the cohesive force of the bent area, thereby enhancing the stiffness of the sealing ring 2 in the force direction, thereby greatly improving the sealing ring 2's ability to resist external pressure. Anti-deformation ability;

[0040] On the other hand, because the sealing rings 1 and 2 are installed in a stacking manner, the pressure distribution of the sealing rings 1 and 2 can be more uniform during use, which effectively reduces the stress concentration on a single sealing ring and reduces the risk of material fatigue and damage.

[0041] Furthermore, by stacking the sealing rings 1 and 2, it is possible to avoid the need for excessive concealed grooves in the outer shell or cover while ensuring good sealing of the tracker, thereby indirectly reducing the difficulty of producing and processing the outer shell and cover.

DETAILED DESCRIPTION

[0061] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] [Example 1]

[0063] In order to address the shortcomings of the existing technology, such as Figure 1 , 2As shown, the present invention provides an alarm tracker with waterproof function, the circuit board 3 is installed inside the shell 1 and the cover 2, and is connected to the shell 1 or the cover 2 via an external snap-on fixing seat; the shell 1 and the cover 2 are threadedly connected, or twist-on connected, and can also be fixed by an external fixing member.

[0064] It should be noted that the positioning module may be based on a satellite positioning system such as GPS, Beidou, GLONASS, etc., and transmit data through a mobile network or satellite communication;

[0065] The above is the prior art well known to those skilled in the art and will not be elaborated in detail here.

[0066] Specifically, Figure 4 , 5 As shown, a cover 2 for an alarm tracker with waterproof function, the sealing ring 1 22 and the sealing ring 23 are made of nitrile rubber or silicone rubber; the sealing ring 23 can be a "Y" type sealing ring, preferably, the sealing ring 1 22 is an "O" type sealing ring; the sealing ring 23 is integrally molded.

[0067] It should be noted that the present invention is an alarm tracker with a waterproof function. Through the provided housing 1 and the cover 2, during the installation of the alarm tracker, the sealing ring 1 22 is firstly put on the inner top outer edge of the cover 2 based on the installation groove 1 21, and then the sealing ring 23 is overlapped on the outer side of the sealing ring 1 22 based on the fitting groove 232 opened thereon, and the sealing ring 23 needs to fit with the cover 2;

[0068] After the sealing ring 1 22 and the sealing ring 2 23 are installed, their geometric centers after installation are closer to the geometric center of the cover 2 than the geometric center of the sealing ring 1 22. At this time, the structural state of the sealing ring 1 22 and the sealing ring 2 23 should be as follows: Figure 5 , 6 As shown here, as shown in the cross-section diagram of the sealing ring 1 22 and the sealing ring 2 23, taking the geometric center of the sealing ring 1 22 as the reference, the thickness of the sealing ring 2 23 after installation, which is distributed on both sides of the upper and lower sides of the geometric center of the sealing ring 1 22, is and ,because , and is subject to the material properties of the sealing ring 23, the direction of the force of the sealing ring 23 is as follows Figure 5 As shown by the arc arrow in the figure, the overlapping of the sealing ring 23 is made more secure.

[0069] After that, the shell 1 and the cover 2 need to be docked. After the shell 1 and the cover 2 are docked, Figure 7In the structural state shown in FIG. 1 , the housing 1 and the cover 2 will squeeze the sealing ring 22 after being connected. Due to the structure of the mounting groove 21, the deformation direction of the sealing ring 22 after being squeezed is Figure 7 The arrows in the figure indicate the direction;

[0070] At the same time, the deformation of the sealing ring 1 22 will squeeze the sealing ring 23, causing the sealing ring 23 to deform. The structural state of the deformed sealing ring 23 and the position state of the petals 231 attached thereto are as shown in FIG. Figure 7 As shown by the dotted line in the figure, a double seal is formed at the joint gap between the shell 1 and the cover 2.

[0071] It is worth mentioning that the sealing ring 23 slides in different directions through the petals 231 thereon after being compressed, and further fills the gap between the two adjacent surfaces of the shell 1 and the cover 2 to form a double sealing layer, which can significantly improve the waterproof performance of the alarm tracker, and at the same time better adapt to the slight tolerance changes of the shell 1 and the cover 2;

[0072] Furthermore, the two petals 231 are in a bent state after deformation, and the van der Waals force therein changes, resulting in an increase in the cohesive force of the bent region, thereby enhancing the rigidity of the sealing ring 23 in the force direction, thereby greatly improving the sealing ring 23's ability to resist external pressure. Anti-deformation ability;

[0073] On the other hand, because the sealing ring 1 22 and the sealing ring 23 are installed in a stacking manner, the pressure distribution of the sealing ring 1 22 and the sealing ring 23 can be more uniform during use, which effectively reduces the stress concentration on a single sealing ring and reduces the risk of material fatigue and damage.

[0074] Furthermore, by stacking the sealing ring 1 22 and the sealing ring 2 23 , it is possible to avoid the need for excessive hidden grooves in the outer shell 1 or the cover 2 while ensuring good sealing of the tracker, thereby indirectly reducing the difficulty of manufacturing and processing the outer shell 1 and the cover 2 .

[0075] In this embodiment, the cover 2 and the housing 1 are connected by the thread groove 13 and the thread 25 provided thereon, and the connection can also be made by an internal screw-on method.

[0076] As a preferred embodiment, the joint between the cover 2 and the housing 1 is provided in a stepped manner, so that when the external pressure is When in operation, since the sealing member is not opposite to the through-slit thereon, the pressure directly received by the sealing member is relatively small, thereby ensuring the sealing performance of the connection between the housing 1 and the cover 2 to the greatest extent.

[0077] [Example 2]

[0078] Based on the above embodiment 1, in order to achieve the best sealing performance between the housing 1 and the cover 2, the two sealing rings 23 on the sealing ring 23 should be deformed in different directions (i.e., not deformed in the same direction) after being compressed. For example, if both petals 231 face the cover 2, a seal can be formed in this state, but the sealing performance and the utilization rate of the sealing ring 23 are obviously not as good as those in the embodiment 1. Figure 7 The structural state of the sealing ring 23 shown:

[0079] Therefore, as a preferred embodiment, Figure 6 As shown, a shell 1 for an alarm tracker with a waterproof function is provided. The shell 1 has a slope 111 on the facing surface of the sealing ring 23 to better accommodate the axial insertion of the sealing ring 23.

[0080] And if Figure 7 As shown, a sealing ring 23 with waterproof function for an alarm tracker is provided, wherein the petals 231 are provided with guide surfaces 233.

[0081] The sealing cover 2 is also provided with a guide surface 221 at the joint between the sealing ring 23 and the sealing ring 2. Figure 7 In the structural state shown, since the guide surface 1 221 is biased toward the geometric center of the cover 2, the sealing ring 23 is supported by both the sealing ring 1 22 and the guide surface 1 221. In the subsequent process of the sealing ring 23 being compressed and deformed, it is more conducive to better deformation guidance of the two petals 231 thereon.

[0082] It should be noted that the present invention is an alarm tracker with waterproof function. By setting the second guide surface 233, similar to the above, in the process of docking the shell 1 and the cover 2, because the petal 231 is provided with the second guide surface 233, when the petal 231 contacts the shell 1, the contact point between the petal 231 and the shell 1 (that is, the force point of the petal 231 based on the shell 1) is in a relatively upper position, such as Figure 7 In this state, when the petal 231 is compressed, based on this stress point, the petal 231 can be guaranteed to slide toward this stress point to the greatest extent, so as to achieve Figure 7 The ideal sealing state is shown.

[0083] Further, such as Figure 8 As shown, a sealing ring 23 for an alarm tracker with a waterproof function is provided, wherein the petal 231 is provided with a groove 234 on the side for fitting with the housing 1.

[0084] It is worth mentioning that the present invention is an alarm tracker with waterproof function. Through the provision of the groove 234, on the one hand, the groove 234 is more conducive to the sealing ring 23 to expand itself under pressure and better fill the gap between the outer shell 1 and the cover 2, thereby enhancing the sealing effect; on the other hand, because the disassembly and assembly of the outer shell 1 and the cover 2 requires axial movement, the groove 234 provided can provide the necessary flexibility and effectively reduce stress concentration to extend the service life of the sealing ring 23; and, in the process of docking the outer shell 1 and the cover 2, the petals 231 on the sealing ring 23 can better fit the inner side of the outer shell 1 based on the groove 234, and the docking fit is higher than that of the petals 231 with a flat surface.

[0085] [Example 3]

[0086] Based on the above embodiment, in order to further ensure the waterproof sealing of the alarm tracker, this embodiment is proposed:

[0087] Specifically, Figure 3 , 4 As shown, in a housing 1 for an alarm tracker with a waterproof function, the radial cross-sectional depth of a sealing groove 11 should not be greater than the cross-sectional radius of a sealing ring 22 .

[0088] Specific, and Figure 3 , 4 As shown, a cover 2 for an alarm tracker with a waterproof function, the opening surface of the mounting groove 21 is slightly more than half of the outer surface of the mounting groove 21, such as Figure 5 The structural state shown in the figure ensures that the sealing ring 1 22 can be securely sleeved without deviation, and the open side reserved thereon serves as the force-applying side for the sealing ring 2 23 .

[0089] It should be noted that the present invention is an alarm tracker with waterproof function, with sealing ring three 24 forming multiple seals for the connection between the outer shell 1 and the cover 2; in addition, sealing groove one 11 and sealing groove two 12 are used to respectively form the movement limit or deformation guide of sealing ring one 22 and sealing ring three 24.

[0090] [Example 4]

[0091] Since the alarm tracker is subject to many external kinetic energy factors, the compactness and stability of its internal structure will also affect the waterproof sealing. Based on the above embodiments, this embodiment is proposed:

[0092] Specifically, Figures 2~4As shown, a housing 1 and a cover 2 for an alarm tracker with a waterproof function, wherein the axial spacing between the wedge-shaped stopper 14 and the square stopper 15 based on the housing 1 is equivalent to the thickness of the circuit board 3; the circuit board 3 is provided with a notch that matches the structure of the wedge-shaped stopper 14, and during installation, the circuit board 3 is moved between the wedge-shaped stopper 14 and the square stopper 15 based on the notch, and then the circuit board 3 is rotated so that the notch is not opposite to the wedge-shaped stopper 14;

[0093] The bottom end of the fitting seat 4 fits with and is plugged into the structure of the limiting groove 26 ; the circuit board 3 is fixedly connected to the fitting seat 4 .

[0094] It is worth mentioning that the present invention is an alarm tracker with waterproof function. During the installation of the circuit board 3, on the one hand, the circuit board 3 is limited in the housing 1 by the wedge-shaped stopper 14 and the square stopper 15.

[0095] On the other hand, the fitting seat 4 attached to the circuit board 3 and matching with the limiting groove 26 structure forms a rotation limit based on the limiting groove 26 and the cover 2, and the "human"-shaped triangular structure is helpful to reduce the risk of resonance between the circuit board 3 and the housing 1.

[0096] [Example 5]

[0097] Based on the above embodiment, in order to ensure the service life of the alarm tracker, the upper cover 2, as one of the most vulnerable parts of the shell, should reduce wear to the greatest extent, and thus the present embodiment is proposed:

[0098] Specifically, Figure 1 , 2 As shown, an alarm tracker with waterproof function has two groups of force grooves 2-1 symmetrically opened on the left and right sides based on the geometric center of the cover 2, so that the torque on the cover 2 is more balanced during the disassembly and assembly process.

[0099] As a preferred embodiment, the present invention is an alarm tracker with a waterproof function. While effectively protecting the cover 2 from external wear, in order not to affect the normal disassembly and assembly of the cover 2 and the housing 1, the cover 2 has a stress groove 2-1 opened thereon. During the process of disassembly and assembly of the cover 2, the cover 2 is rotated based on the two stress grooves 2-1.

[0100] In the above embodiments, those skilled in the art will appreciate that in order for sealing ring 1 22, sealing ring 23, and sealing ring 3 24 to be securely sleeved onto cover 2, the original non-deformed inner diameter of sealing ring 1 22, sealing ring 23, and sealing ring 3 24 should be smaller than the inner diameter of the portion where they are positioned on cover 2.

[0101] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed for protection.
