Frequency jammers in this technology typically have a built-in battery for power. To ensure uninterrupted operation, the battery can be replaced for continuous power. However, the battery in a frequency jammer is usually secured with screws or other fasteners, making battery replacement or installation a cumbersome process. Utility Model Content

[0038] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

Therefore, they should not be construed as limitations on this utility model.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] Frequency jammers in related technologies typically have a built-in battery for power. To ensure uninterrupted operation, the battery can be replaced for continuous power. However, the battery is usually secured with screws or other fasteners, making battery replacement or installation cumbersome. Furthermore, the battery compartment lacks a stable and simple locking mechanism, hindering quick battery replacement and locking, and compromising battery stability during movement, making it susceptible to damage from impacts.

[0045] In view of the above-mentioned problems, this utility model provides a battery compartment structure, a frequency jammer and a wireless signal shielding system, which facilitates battery disassembly and replacement and can maintain the stability of the battery when it moves with external devices.

[0046] See Figure 2 and Figure 6 As shown, Figure 2 This is a schematic diagram of the overall structure of the battery compartment according to some embodiments of the present invention. Figure 6 This is a schematic diagram of the battery compartment structure provided according to some embodiments of the present invention with the compartment body opened. One embodiment of the present invention first provides a battery compartment structure, which may include a compartment body 100 and a switch assembly 200.

[0047] The compartment 100 has a receiving cavity 102 for accommodating the battery 10. An opening 101 communicating with the receiving cavity 102 is provided at one end of the compartment 100 along a first direction. A limiting member 110 is provided in the compartment 100. A switch assembly 200 is movably connected to at least one end of the compartment 100 along a second direction. A snap-fit ​​member 2211 is provided on the switch assembly 200. The second direction is not parallel to the first direction. The snap-fit ​​member 2211 cooperates with the limiting member 110 to change the area of ​​the switch assembly 200 blocking the opening 101.

[0048] It is understood that the receiving cavity 102 with opening 101 can be adapted to the volume of the battery 10 so that the battery 10 is fitted inside the compartment 100, improving the stability of the battery 10 during movement with external devices. The opening 101 facilitates the entry and exit of the battery 10 from the compartment 100. The second direction is not parallel to the first direction; for example, the projections of the first and second directions on the same plane intersect, or the first and second directions are perpendicular to each other. As one embodiment, if the first direction is defined as the height direction of the compartment 100, then the opening 101 is formed at the top of the compartment 100.

[0049] To prevent the battery 10 located inside the compartment 100 from sliding out of the opening 101, a switch assembly 200 is provided on the compartment 100. This switch assembly 200 is movably (including rotating and sliding) mounted on the compartment 100 and can change the area of ​​its obstruction of the opening 101 under the influence of, for example, external force (e.g., a human hand). For example, if the switch assembly 200 is positioned to obstruct the opening 101 of the compartment 100, and if the obstruction area of ​​the switch assembly 200 is large, such that the area of ​​the unobstructed portion of the opening 101 is smaller than the area of ​​the end face of the battery 10 facing the opening 101, then the battery 10 inside the compartment 100 can be limited. In other words, the switch assembly 200 located at the opening 101 can block the battery 10, preventing it from sliding out of the compartment 100 to a certain extent. Similarly, the switch assembly 200 can also be moved away from the opening 101 by an external force (such as a human hand) to reduce the obstruction area of ​​the opening 101 until the unobstructed part of the opening 101 is sufficient to allow the battery 10 to enter or exit, or until the opening 101 is fully exposed, so as to facilitate the removal of the battery 10 from the compartment 100.

[0050] Of course, in order to prevent the battery 10 from sliding out of the compartment 100, it is also necessary to keep the switch assembly 200 at the opening 101 after the battery 10 enters the compartment 100, so as to continuously block the opening 101. In this example, a limiting component 110 is provided on the compartment 100, and a snap-fit ​​component 2211 adapted to the limiting component 110 is provided on the switch assembly 200. Through the cooperation of the two, the purpose of continuously and securely keeping the switch assembly 200 at the opening 101 can be achieved.

[0051] In some embodiments, the specific structure of the limiting component 110 and the locking component 2211 can be such that the limiting component 110 is a limiting hook fixed to the side wall of the compartment 100, and the locking component 2211 is a crescent lock rotatably mounted on the switch assembly 200. When the switch assembly 200 moves into position under external force, the handle of the crescent lock is manually rotated to engage its semi-circular locking hook with the limiting hook on the side wall of the compartment 100, thereby locking the switch assembly 200 at the opening 101 of the compartment 100. Conversely, if it is necessary to remove the battery 10, the crescent lock is rotated in the opposite direction to unlock it. This configuration is simple and can improve the efficiency of replacing the battery 10.

[0052] Additionally, the switch assembly 200 can be slidably mounted on the compartment 100, for example, in the form of a sliding window, allowing it to block the opening 101 by manually pushing the switch assembly 200. Alternatively, the switch assembly 200 can be rotated onto the compartment 100, for example, in the form of a casement window, allowing it to block the opening 101 by manually rotating the switch assembly 200. Of course, the connection method between the switch assembly 200 and the compartment 100 can be determined based on the space surrounding the battery compartment structure, and no specific limitations are imposed here. Furthermore, the switch assembly 200 can also slide or rotate automatically. For example, it may contain a controller, sensor, and drive assembly. When the sensor detects that a battery has entered the compartment 100, the controller automatically controls the switch assembly 200 to block the opening 101 via the drive assembly. When it is necessary to remove the battery 10, the controller, upon receiving a command, can automatically control the switch assembly 200 to reduce or remove the blockage of the opening 101.

[0053] Besides locking the switch assembly 200 to the opening 101 using the crescent lock and limit hook, the switch assembly 200 can also be elastically connected to the compartment 100, with the limit component 110 and the locking component 2211 configured as conventional slot and post locking structures. By appropriately setting the elastic direction of the switch assembly 200 and the locking direction of the limit component 110 and the locking component 2211, the switch assembly 200 can be continuously blocked at the opening 101 of the compartment 100. In other words, the elastic force keeps the limit component 110 and the locking component 2211 continuously locked, preventing the switch assembly 200 from moving in either the first or second direction. This method only requires external force to overcome the elastic force during the movement of the switch assembly 200, eliminating the need for additional locking operations, making it easier to operate and improving the efficiency of loading and unloading the battery 10.

[0054] Of course, the specific structure of the aforementioned limiting component 110 and locking component 2211 can be understood by referring to the following example, and will not be repeated here.

[0055] It should be noted that, as Figure 2 As shown, if the first direction is defined as the height direction of the compartment 100, then the second direction can be the width direction of the compartment 100 perpendicular to the first direction. In this embodiment, the compartment 100 can specifically be set as a cuboid structure adapted to the battery 10 structure, that is, the projection of the compartment 100 along the height direction can be a rectangle, which includes a long side and a short side. Then, the width direction of the compartment 100 refers to the extension direction of the long side. One end of the switch assembly 200 can be movably connected to the side wall of the compartment 100 where the short side is located, and the other end of the switch assembly 200 can be freely set so as to block the opening 101 by external force. Of course, the second direction can also be a direction that intersects with the first direction, and the compartment 100 can also be set as other structures adapted to the battery 10 structure. No specific restrictions are made here.

[0056] Furthermore, to ensure the stability of the battery 10 during movement with external devices, it can be designed to fit against the surface of the battery 10 when the switch assembly 200 is obstructed at the opening 101 of the housing 100. Alternatively, a buffer pad can be provided on the side of the switch assembly 200 facing the battery 10, so that the buffer pad fits against the surface of the battery 10. Or, a spring can be provided on the side of the switch assembly 200 facing the battery 10, so that the spring fits against the surface of the battery 10, but there are no specific limitations.

[0057] In this embodiment of the invention, a switch assembly 200 is movably disposed at at least one end of the compartment 100, and a locking member 2211 is provided on the switch assembly 200 that can cooperate with the upper limit member 110 of the compartment 100 for limiting. After the battery 10 is placed into the receiving cavity 102 through the opening 101, the switch assembly 200 moves to a position that can block the opening 101. The cooperation of the locking member 2211 and the limiting member 110 ensures that the switch assembly 200 continuously blocks the opening 101 of the compartment 100, thereby securing the battery 10 within the compartment 100. This design is not only simple in structure but also facilitates the removal of the battery 10, thus improving the efficiency of battery replacement.

[0058] Below, we will combine the appendix Figure 1 -Appendix Figure 6 The specific structure of the battery compartment structure provided in the embodiments of this utility model will be described. Figure 3 This is a schematic diagram of the battery compartment structure provided according to some embodiments of the present invention with the compartment closed. Figure 4 This is a schematic diagram of the limiting component and the locking component provided according to some embodiments of the present invention in the released state.

[0059] like Figure 2As shown, in some embodiments, the switch assembly 200 includes a spring-loaded member 220, and a snap-fit ​​member 2211 is disposed on the spring-loaded member 220. The spring-loaded member 220 is adapted to switch between a limited state and a released state. In the limited state, the snap-fit ​​member 2211 snaps into the limited member 110, and in the released state, the snap-fit ​​member 2211 disengages from the limited member 110.

[0060] Specifically, the spring-loaded component 220 provides continuous elastic force for the engagement of the locking component 2211 and the limiting component 110. For example, after the battery 10 is placed in the compartment 100, the spring-loaded component 220 is manually moved towards the opening 101 of the compartment 100. When it is in place, that is, when the locking component 2211 is close to the limiting component 110, the spring-loaded component 220 is deformed by manually applying force, so that the locking component 2211 engages with the limiting component 110. After engagement is completed (in the limiting state), under the elastic force of the spring-loaded component 220, the locking component 2211 continues to engage with the limiting component 110, thereby achieving the purpose of securing the spring-loaded component 220 at the opening 101 to block the opening 101 and limiting the battery 10 within the compartment 100.

[0061] Conversely, if it is necessary to remove the battery 10 from the compartment 100, manual force is applied to deform the spring-loaded component 220 again so that the locking component 2211 can separate from the limiting component 110, thereby releasing the spring-loaded component 220. In this released state, the spring-loaded component 220 can be manually moved away from the opening 101, thereby exposing the opening 101 so that the battery 10 can be removed.

[0062] This setup only requires manual force to overcome the elasticity of the switch assembly 200 during its movement, eliminating the need for additional locking operations. This simplifies the operation and greatly improves the efficiency of installing and removing the battery 10.

[0063] To achieve effective shielding of the opening 101 by the switch assembly 200, thereby improving the stability of the battery 10 within the housing 100, such as... Figure 2 As shown, in some embodiments, the switch assembly 200 further includes a cover member 210, which is movably connected to the housing 100, and a spring-back member 220 is connected to the cover member 210.

[0064] Specifically, the cover component 210 is rotatably or slidably mounted on the compartment 100. Taking the cover component 210 rotatably mounted on the compartment 100 as an example, one end of the cover component 210 is rotatably connected to the compartment 100, and the other end can be close to or away from the opening 101. Combined with the spring-loaded component 220 mounted on the other end of the cover component 210, when the cover component 210 covers at least part of the opening 101, the spring-loaded component 220 provides continuous elasticity, causing the locking component 2211 to engage with the limiting component 110, thereby achieving the purpose of securing the cover component 210 at the opening 101. The side of the cover component 210 facing the battery 10 can contact the battery 10, thereby ensuring the stability of the battery 10 during movement with external devices and avoiding or mitigating the problem of damage caused by the battery 10 shaking.

[0065] like Figures 2 to 4 As shown, in some embodiments, the springback member 220 may include a slider 221 and an elastic member 222. The slider 221 is slidably connected to the cover member 210, and a locking member 2211 is disposed at the end of the slider 221 near the limiting member 110. One end of the elastic member 222 is limited to the cover member 210, and the other end is limited to the slider 221.

[0066] Specifically, one end of the elastic element 222 can abut or connect with the cover member 210, and the other end of the elastic element 222 can connect or abut with the sliding element 221. The sliding element 221 can slide relative to the cover member 210 in a second direction, and by placing the elastic element 222 (e.g., a spring) between the cover member 210 and the sliding element 221, the position of the sliding element 221 relative to the cover member 210 can be adjusted. In one example, the engaging member 2211 is a limiting groove formed at the end of the sliding element 221, and the limiting member 110 is a positioning post provided on the outside of the compartment 100, which is adapted to engage with the limiting groove.

[0067] Specifically, a limiting groove is formed at the end of the sliding member 221 facing away from the elastic member 222. In the limiting state, the elastic member 222 drives the sliding member 221 to move in the second direction, so that the limiting groove engages with the positioning post. It can be understood that the limiting groove provided at the end of the sliding member 221 can move with the movement of the sliding member 221. After the battery 10 is placed in the compartment 100, the cover component 210 can be manually rotated, thereby causing the sliding member 221, the elastic member 222, and the limiting groove connected to the cover component 210 to rotate together toward the opening 101 of the compartment 100. When the rotation is in place, that is, when the limiting groove is close to the positioning post, the elastic member 222 is deformed by manually applying force to the sliding member 221, so that the limiting groove and the positioning post engage. Once the engagement is complete, the elastic element 222 releases force, causing the limiting groove to remain engaged with the positioning post, thereby securing the cover component 210 at the opening 101 to block the opening 101 and limiting the battery 10 within the compartment 100.

[0068] Conversely, if it is necessary to remove the battery 10 from the compartment 100, force is manually applied to the sliding member 221 to deform the elastic member 222 again, so that the limiting groove and the positioning post are separated, thereby putting the elastic member 222 in a released state. In this released state, the cover member 210, the sliding member 221, the elastic member 222 and the limiting groove can be manually moved away from the opening 101, thereby exposing the opening 101 so that the battery 10 can be removed.

[0069] It should be noted that the deformation of the elastic element 222 mentioned above can be, for example, the compression or elongation of a spring under the action of an external force.

[0070] like Figures 2 to 5 As shown, in some embodiments, the sliding member 221 can be configured as a U-shaped plate, which engages with the opening 101 of the compartment 100. Specifically, the U-shaped sliding member 221 includes a second top plate 2212 and two opposing second side walls 2213. The second top plate 2212 is used to connect with or abut against the elastic member 222, and the two second side walls 2213 cover the outer sides of the two side walls of the cover member 210. The positioning post is provided on the outer side wall of the compartment 100, and the limiting groove is provided on at least one side of the second side wall 2213 to fit and engage with the positioning post. To enhance the stability of the cover member 210 in closing the opening 101 of the compartment 100, positioning posts can be provided on both opposing side walls of the compartment 100. Similarly, limiting grooves are also provided on both second side walls 2213.

[0071] In addition to the above-mentioned snap-fit ​​method, in some embodiments (not shown in the figure), the snap-fit ​​component 2211 is a positioning post provided at the end of the sliding member 221, and the limiting component 110 is a limiting groove formed on the outside of the compartment 100, with the positioning post and the limiting groove being adapted to snap-fit.

[0072] Specifically, protrusions can be provided on the outer side wall of the compartment 100, and limiting grooves can be constructed in the protrusions, while positioning posts are provided at the two second side walls 2213 of the U-shaped sliding member 221. Furthermore, protrusions can be provided on both opposite side walls of the compartment 100, and positioning posts can be provided at the two second side walls 2213 of the U-shaped sliding member 221, to enhance the stability of the closing member 210 closing the opening 101 of the compartment 100.

[0073] like Figure 3 , Figure 4 As shown, in some embodiments, the cover component 210 includes an adapter 211, one end of which is rotatably connected to one end of the compartment 100 via a pivot 300.

[0074] Specifically, the adapter 211 can be a U-shaped cover. One end of the U-shaped adapter 211 is mounted on one end of the compartment 100 via a pivot 300, and the other end can cover the opening 101 or rotate away from the opening 101 under external force. The U-shaped adapter 211 includes a first top plate 2112 and two opposing first side walls 2113. The two first side walls 2113 of the U-shaped adapter 211 are located in the same direction as the two side walls of the compartment 100. The aforementioned U-shaped sliding member 221 is adapted to cover the U-shaped adapter 211. This arrangement not only facilitates the first top plate 2112 to block the opening 101, i.e., adapts to cover the opening 101, but also facilitates the setting of the first limiting part 2111 at the first side wall 2113 for sliding connection with the sliding member 221, making the structural layout of the entire switch assembly 200 more rational.

[0075] like Figure 4 As shown, in some embodiments, the adapter 211 is provided with a first limiting part 2111, and the slider 221 is provided with a second limiting part 2214, and the first limiting part 2111 and the second limiting part 2214 are adapted to be inserted into each other.

[0076] Specifically, the sliding connection between the adapter 211 and the slider 221 can be achieved through the fitting and insertion of the first limiting part 2111 on the adapter 211 and the second limiting part 2214 on the slider 221. In one example, the first limiting part 2111 is a strip-shaped channel formed on the adapter 211, and the second limiting part 2214 is a slider disposed on the slider 221. The strip-shaped channel extends along the second direction, and the slider is embedded in the strip-shaped channel. This arrangement ensures that the elastic member 222 applies force to the slider 221, causing the slider 221 to slide along the second direction to achieve the engagement or disengagement of the engaging member 2211 and the limiting member 110. Moreover, it ensures the synchronicity of the slider 221 and the adapter 211 when near or far from the opening 101, making manual operation more convenient and improving the smoothness of operation.

[0077] In another example (not shown in the figure), the first limiting part 2111 is a slider provided on the adapter 211, and the second limiting part 2214 is a strip channel formed on the slider 221. The specific positions of the strip channel and the slider are not limited here, as long as the slider 221 can slide relative to the adapter 211 in the second direction.

[0078] like Figure 3 As shown, in some embodiments, the slider 221 is provided with a handle 2215 on the side opposite to the adapter 211.

[0079] Specifically, since the slider 221 is covered outside the adapter 211, in order to facilitate the slider 221 sliding relative to the adapter 211 and to rotate the slider 221 and the adapter 211 at the same time, a handle 2215 is provided on the outside of the second top plate 2212 of the slider 221 for easy manual gripping.

[0080] In some embodiments, the adapter 211 and / or the slider 221 have multiple weight-reducing grooves (not shown). Specifically, multiple weight-reducing grooves are provided on the adapter 211 and the slider 221, which can reduce the weight of the entire switch assembly 200, making it easier to manually turn the switch assembly 200 on or off, and further improving the efficiency of battery 10 replacement.

[0081] like Figure 2 As shown, in some embodiments, the battery compartment structure includes two sets of switch assemblies 200, which are respectively disposed at both ends of the compartment body 100 along the second direction.

[0082] Specifically, the aforementioned switch assembly 200 can be installed on only one side of the compartment 100, or it can be symmetrically installed at opposite ends of the compartment 100. Installing two sets of switch assemblies 200 can not only increase the shielding area of ​​the opening 101 and improve the stability of the battery 10 inside the compartment 100, but also improve manual operability to increase the loading and unloading speed, thereby improving the efficiency of replacing the battery 10.

[0083] Figures 2-6The specific operation process of the battery compartment structure in the illustrated embodiment is as follows: After the battery 10 is placed in the compartment body 100, the cover component 210 can be manually rotated, thereby causing the sliding member 221, the elastic member 222, and the limiting groove connected to the cover component 210 to rotate together toward the opening 101 of the compartment body 100. When the rotation is in place, that is, when the limiting groove is close to the positioning post, the sliding member 221 is manually forced to deform (e.g., compress) the elastic member 222, so that the limiting groove and the positioning post can be engaged. After the engagement is completed, under the release force of the elastic member 222, the limiting groove continues to engage with the positioning post, thereby achieving the purpose of securing the cover component 210 at the opening 101 to block the opening 101 and limiting the battery 10 within the compartment body 100.

[0084] Conversely, if it is necessary to remove the battery 10 from the compartment 100, force is manually applied to the sliding member 221 to deform (e.g., compress) the elastic member 222 again, so that the limiting groove and the positioning post can be separated, thereby releasing the elastic member 222. In this released state, the cover member 210, the sliding member 221, the elastic member 222 and the limiting groove can be manually moved away from the opening 101, thereby exposing the opening 101, so that the battery 10 can be removed.

[0085] As one embodiment, in addition to manual operation, the rotation of the cover component 210 of the battery compartment structure, the engagement and disengagement of the limiting groove and the positioning post can also be achieved by other external forces, such as by setting a controller, sensor and drive component inside to achieve automatic control, which will not be described in detail here.

[0086] like Figure 1 As shown, Figure 1 This is a schematic diagram of the internal structure of a frequency jammer according to some embodiments of the present invention. The present invention also provides a frequency jammer, which may include a housing 20 and the battery compartment structure described in the above embodiments. The housing 20 has a cavity 21, and the battery compartment structure is disposed within the cavity 21.

[0087] It is understood that the frequency jammer provided in this example can be a portable frequency jammer, such as a trolley case type frequency jammer. Its housing 20 is usually assembled from an upper housing and a lower housing, and the battery compartment structure is located in the cavity 21 after the upper and lower housings are connected. When replacing the battery 10, the upper housing needs to be opened first to expose the battery compartment structure. Then, the two sets of switch assemblies 200 are manually pulled and rotated to expose the opening 101. After the new battery 10 is placed into the compartment 100, the switch assembly 200 is manually rotated again to the opening 101, and the elastic member 222 is deformed to make the limiting member 110 engage with the locking member 2211, thus locking the switch assembly 200 to the opening 101.

[0088] This utility model embodiment also provides a wireless signal jamming system, which includes at least one frequency jammer as described in the above embodiment.

[0089] It is understood that the wireless signal jamming system includes, for example, at least one frequency jammer and a jammer control device as described in the above embodiments. The jammer control device is used to control the frequency jammer. The jammer control device can control the frequency jammer to transmit radio interference signals through various wireless or wired methods, and this embodiment of the present invention does not limit this.

[0090] Alternatively, the wireless signal jamming system may include, for example, at least one frequency jammer as described in the above embodiments. One frequency jammer controls all the frequency jammers. The frequency jammers can communicate with each other via various wireless or wired methods. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; however, as long as the combinations of these technical features are not contradictory, they should be considered within the scope of this specification.

[0091] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
