Description

Technical Field

[0001] The present application relates to the technical field of communication terminals, and in particular to a signaling device and a mobile signaling device. Background Art

[0002] A GPS antenna is an antenna used to receive and transmit GPS signals. It captures signals from GPS satellites and calculates a location. It is widely used in navigation, positioning, and measurement. A 4G antenna, on the other hand, receives and transmits 4G network signals. 4G antennas can be connected to devices like mobile phones and tablets, enabling them to connect to the 4G network and enjoy high-speed network services. The two have different functions and features: GPS antennas are used for navigation and positioning, while 4G antennas connect to communication networks. Both play a vital role in modern communication terminals, providing stable and fast communication.

[0003] Because the GPS antenna and the second antenna have different functions and characteristics, if the same device needs to receive both GPS and 4G signals, two antennas with different functions are required. When the two antennas are close together, mutual interference between the signals causes the GPS and 4G antennas to start up more slowly, reducing their efficiency. When the two antennas are far apart, integration and installation become difficult, leading to higher production costs and reduced economic benefits. Utility Model Content

At least part of the first antenna and at least part of the second antenna extend out of the first opening, and at least part of the first antenna and at least part of the second antenna are at least partially arranged in the second inner cavity.

[0009] In some embodiments, the protective cover includes a second wall facing away from the device housing, and a distance from the first wall to the second wall is L in a direction perpendicular to the first wall, and the distance L satisfies: 2cm≤L≤5cm.

[0010] In some embodiments, the second wall surface is parallel to the first wall surface, the first projection plane is parallel to the first wall surface, the second wall surface forms a first orthographic projection on the first projection plane, the first opening forms a second orthographic projection on the first projection plane, and the first orthographic projection coincides with the second orthographic projection.

[0011] In some embodiments, the first antenna and the second antenna are arranged with an interval between them along a direction parallel to the first wall.

[0012] In some embodiments, the first antenna and the second antenna are spaced apart by a distance N, and the distance N satisfies: 1 cm ≤ N ≤ 4 cm, so as to ensure that the first antenna and the second antenna have little influence in a working state.

[0013] In some embodiments, the device housing includes a first groove, the first opening is provided in the first groove, the first groove includes a third wall parallel to the first wall, and the distance from the first wall to the third wall along a direction perpendicular to the first wall is M, and the distance M satisfies: 0.5cm≤M≤1cm.

[0014] In some embodiments, the thickness of the protective cover is set to A, the thickness of the device housing is set to B, and the thickness A and the thickness B satisfy: A≤B.

[0015] In some embodiments, the protective cover includes a partition device, which is arranged in the second inner cavity to separate the second inner cavity into two sub-cavities, and the second antenna and the first antenna are respectively arranged in the sub-cavities.

[0016] In some embodiments, the protective cover and the device housing are connected by threads, so that the protective cover is configured to be quickly detachable;

[0017] and / or,

[0018] The protective cover and the signal transmitting portion are connected by threads, so that the protective cover is configured to be quickly disassembled;

[0019] and / or,

[0020] The signal transmitting part and the device housing are connected via threads, so that the signal transmitting part is configured to be quickly disassembled.

[0021] A second aspect of the present application further provides a mobile messaging device, comprising:

[0022] The signaling device according to any one of the above embodiments;

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] The technical solution of the present application proposes a signaling device comprising: a device housing, a protective cover, and a transmitting unit. The device housing defines a first inner cavity, including a first wall having a first opening disposed thereon; the protective cover is disposed on the first opening to cover the first opening, extending beyond the first opening, and defining a second inner cavity; the transmitting unit is disposed within the first inner cavity and includes a first antenna and a second antenna, at least a portion of the first antenna and at least a portion of the second antenna extending beyond the first opening, and at least a portion of the first antenna and at least a portion of the second antenna being at least partially disposed within the second inner cavity. By arranging at least a portion of the first antenna and the second antenna within the second inner cavity, the first and second antennas can be easily integrated and installed, thereby reducing production costs and increasing economic benefits. Furthermore, by extending the protective cover beyond the first opening, the second inner cavity defined by the protective cover can be defined, thereby providing more space to accommodate the antennas. Therefore, by at least partially arranging the first antenna and the second antenna in the second inner cavity, the distance between the first antenna and the second antenna is large, and the mutual interference between the signals is low, thereby ensuring that the first antenna and the second antenna start up quickly and improving the utilization efficiency of both.

[0027] Furthermore, by arranging the first antenna and the second antenna in a second inner cavity away from the first inner cavity, the transmitting part is separated from other electronic components in the transmitting part. When other electronic components in the signal device are working, the electrical signals generated by the other electronic components have less interference with the first antenna and the second antenna, thereby ensuring that the first antenna and the second antenna start up faster and improving the utilization efficiency of both.

[0054] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0055] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0056] In addition, when an element is described as being “fixed to” another element, it may be directly on the other element or one or more intervening elements may be present therebetween. When an element is described as being “connected to” another element, it may be directly connected to the other element or one or more intervening elements may be present therebetween.

[0057] In addition, if the description of "first", "second" and the like is involved in the embodiments of the present application, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears throughout the text, it means that the three parallel schemes include "A and / or B", including A scheme, or B scheme, or A and B scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the scope of protection claimed by the present application.

[0058] Because the GPS antenna and the second antenna have different functions and characteristics, if the same device needs to receive GPS signals and 4G signals, two different function antennas are needed. When the two antennas are close, due to the mutual interference between the signals, the GPS antenna and the 4G antenna start slowly, reducing the use efficiency of the two. When the two antennas are far apart, it is difficult to integrate and install, resulting in high production cost and reducing economic benefit.

[0059] To solve the above problems, the present application provides a signal device 10, see Figures 1 to 6The signal device 10 includes a device housing 100, a protective cover 200, and a signal transmitter 300. In some embodiments, the signal device 10 is configured to transmit or receive GPS (Global Positioning System), Wi-Fi (Wireless Fidelity, also known as mobile hotspot), and 4G (The 4th generation mobile communication technology) signals. In some embodiments, the signal device 10 is configured to transmit or receive GPS, Wi-Fi, and 5G (The 5th generation mobile communication technology) signals. Wi-Fi and 4G signals can be received or transmitted using the same antenna, and Wi-Fi and 5G signals can also be received or transmitted using the same antenna, but GPS signals require a separate antenna for reception or transmission. In some embodiments, the signal device 10 is configured to quickly start up in an operational state and implement the function of transmitting or receiving signals. In some embodiments, the signal device 10 includes a GPS component, a Wi-Fi component, and a 4G component, each of which is configured to process the corresponding signals. It should be noted that the GPS component can be started in various ways, including hot start, warm start, and cold start. During a hot start, the GPS component saves the last calculated positions of visible satellites, the almanac, and Coordinated Universal Time. After restarting, the GPS component starts at a fast speed. During a warm start, the GPS component saves the last calculated positions of satellites, the almanac, and Coordinated Universal Time, and saves data for satellites that are not currently visible. After restarting, the GPS component attempts to acquire current satellites and signals and calculate its new position. The GPS component starts at a medium speed. During a cold start, the GPS component clears all historical information and restarts. It then attempts to locate and lock onto satellites. Because there is no previous information, the GPS component starts at a slow speed.

[0060] The device housing 100 can have various shapes. In some embodiments, the device housing 100 can have a cuboid shape. In other embodiments, the device housing 100 can have a cylindrical shape. In other embodiments, the device housing 100 can have a polygonal shape. In some embodiments, the device housing 100 has a cuboid shape. The device housing 100 defines a first inner cavity 110. In some embodiments, the first inner cavity 110 is configured to accommodate GPS components, Wi-Fi components, and 4G components. The device housing 100 includes a first wall 120 disposed at one end of the device housing 100 away from the first inner cavity 110. In some embodiments, the first wall 120 is a flat wall. In other embodiments, the first wall 120 is a curved wall. The first wall 120 has a first opening 130 disposed thereon. The first opening 130 can have various shapes. In some embodiments, the first opening 130 has a square shape. In other embodiments, the first opening 130 has a circular shape. In other embodiments, the first opening 130 has a polygonal shape. In some embodiments, the first opening 130 has a square shape. In some embodiments, the first opening 130 has an axis perpendicular to the first wall 120. The device housing 100 can be made of various materials. In some embodiments, the device housing 100 is made of a material having signal shielding properties. For example, the device housing 100 can be made of copper, nickel, or other materials.

[0061] The protective cover 200 can have various shapes. In some embodiments, the protective cover 200 can have a cuboid shape. In other embodiments, the protective cover 200 can have a cylindrical shape. In other embodiments, the protective cover 200 can have a polygonal shape. In some embodiments, the protective cover 200 has a cuboid shape. The protective cover 200 is disposed on the first opening 130 to cover the first opening 130. The protective cover 200 defines a second inner cavity 210. It should be noted that the second inner cavity 210 and the first inner cavity 110 are connected through the first opening 130. The protective cover 200 extends out of the first opening 130, i.e., in a direction parallel to the first wall 120, the protective cover 200 extends out of the first opening 130 in a direction away from the first inner cavity 110. A second projection plane is a plane perpendicular to the first wall 120. The first inner cavity 110 forms a third orthographic projection on the second projection plane, and the second inner cavity 210 forms a fourth orthographic projection on the second projection plane. In a direction perpendicular to the first wall 120, the fourth orthographic projection at least partially does not coincide with the third orthographic projection. The protective cover 200 can be made of various materials. In some embodiments, the protective cover 200 is made of a material without signal shielding properties. For example, the protective cover 200 can be made of polyethylene, graphene, or other materials.

[0062] The transmitter 300 is disposed within the first inner cavity 110 and includes a first antenna 310 and a second antenna 320. The first antenna 310 is configured to receive or transmit GPS signals, while the second antenna 320 is configured to receive or transmit 4G signals. At least a portion of the first antenna 310 and at least a portion of the second antenna 320 extend out of the first opening 130. Specifically, the first antenna 310 forms a fifth orthographic projection on the second projection plane, and the second antenna 320 forms a sixth orthographic projection on the second projection plane. Along a direction perpendicular to the first wall 120, the fifth orthographic projection at least partially does not overlap with the third orthographic projection, and the sixth orthographic projection at least partially does not overlap with the third orthographic projection. At least a portion of the first antenna 310 and at least a portion of the second antenna 320 are at least partially disposed within the second inner cavity 210. Specifically, the fifth orthographic projection at least partially overlaps with the fourth orthographic projection, and the sixth orthographic projection at least partially overlaps with the fourth orthographic projection. By disposing at least a portion of the first antenna 310 and the second antenna 320 within the second inner cavity 210, the first antenna 310 and the second antenna 320 can be easily integrated and installed, thereby reducing production costs and increasing economic benefits. Furthermore, by extending the protective cover 200 through the first opening 130, the protective cover 200 defines the second inner cavity 210, thereby providing more space for accommodating the antennas. Therefore, by disposing at least a portion of the first antenna 310 and the second antenna 320 within the second inner cavity 210, the greater distance between the first antenna 310 and the second antenna 320 reduces the degree of mutual interference between the GPS and 4G signals, ensuring a faster startup speed for the first antenna 310 and the second antenna 320, thereby improving the efficiency of both. In some embodiments, in the prior art, when the protective cover 200 is not used to provide more space, the cold start time of the first antenna 310 is T1, and the time T1 satisfies: 14min≤T1≤16min. For example, T1 can be 14min, 14min30sec, 15min, 15min30sec, 16min, etc.; in the present application, the cold start time of the first antenna 310 is T2, and the time T2 satisfies: 30sec≤T2≤1min30sec. For example, T2 can be 30sec, 45sec, 1min, 1min15sec, 1min30sec, etc.; it can be seen that the second inner cavity 210 defined by the protective cover 200 can provide more space to accommodate the antenna, and the mutual interference between GPS and 4G signals is low, ensuring that the first antenna 310 and the second antenna 320 start up at a faster rate.

[0063] It should be noted that by arranging the first antenna 310 and the second antenna 320 in the second inner cavity 210 away from the first inner cavity 110, the signaling unit 300 is separated from other electronic components in the signaling unit 300, so that when other electronic components in the signal device 10 are working, the electrical signals generated by the other electronic components have less interference on the first antenna 310 and the second antenna 320, and the starting rate of the first antenna 310 and the second antenna 320 is faster, and the use efficiency of the two is improved.

[0064] The protective cover 200 includes a second wall surface 220 away from the device shell 100, and the second wall surface 220 is located at one end of the second inner cavity 210. It can be understood that in some embodiments, the second wall surface 220 is a planar wall. In other embodiments, the second wall surface 220 is a curved wall. In the direction perpendicular to the first wall surface 120, the distance between the first wall surface 120 and the second wall surface 220 is L, see Figure 6 It should be noted that the distance between the first wall surface 120 and the second wall surface 220 is the distance between the center of the first wall surface 120 and the center of the second wall surface 220 in the direction perpendicular to the first wall surface 120. When the distance L is large, the protective cover 200 will protrude out of the device shell 100, so that the first antenna 310 and the second antenna 320 are more difficult to integrate and install. When the distance L is small, the protective cover 200 will protrude out of the device shell 100, so that the height of the second inner cavity 210 is reduced, and the first antenna 310 and the second antenna 320 will generate greater interference. Therefore, the size of the distance L should be moderate, and under the condition that the first antenna 310 and the second antenna 320 generate less interference, the first antenna 310 and the second antenna 320 are more easily integrated and installed. In some embodiments, the distance L satisfies: 2cm≤L≤5cm, and for example, L can be 2cm, 3cm, 4cm, 5cm, etc., so as to ensure that the size of the distance L is moderate, the first antenna 310 and the second antenna 320 generate less interference, and the first antenna 310 and the second antenna 320 are more easily integrated and installed.

[0065] In some embodiments, the second wall surface 220 is a planar wall, and the second wall surface 220 is parallel to the first wall surface 120. The first projection plane is parallel to the first wall surface 120, the second wall surface 220 forms a first orthographic projection on the first projection plane, the first opening 130 forms a second orthographic projection on the first projection plane, and the first orthographic projection coincides with the second orthographic projection, so as to ensure that the area of the first orthographic projection is greater than or equal to the area of the second orthographic projection, and the first orthographic projection covers the second orthographic projection.

[0066] The first antenna 310 and the second antenna 320 are arranged at intervals along a direction parallel to the first wall surface 120. In some embodiments, the first antenna 310 and the second antenna 320 are arranged at intervals along a length direction of the protective cover 200. In other embodiments, the first antenna 310 and the second antenna 320 are arranged at intervals along a width direction of the protective cover 200. It should be noted that the protective cover 200 forms a seventh orthographic projection in a first projection plane, the length direction of the protective cover 200 is a length direction of the seventh orthographic projection, and the width direction of the protective cover 200 is a width direction of the seventh orthographic projection.

[0067] The first antenna 310 and the second antenna 320 are arranged at intervals along a direction parallel to the first wall surface 120. In some embodiments, the first antenna 310 and the second antenna 320 are arranged at intervals along a length direction of the protective cover 200. In other embodiments, the first antenna 310 and the second antenna 320 are arranged at intervals along a width direction of the protective cover 200. It should be noted that the protective cover 200 forms a seventh orthographic projection in a first projection plane, the length direction of the protective cover 200 is a length direction of the seventh orthographic projection, and the width direction of the protective cover 200 is a width direction of the seventh orthographic projection. Figure 4 It should be noted that the interval distance between the first antenna 310 and the second antenna 320 is a distance from a center of the first antenna 310 to a center of the second antenna 320. When the distance N is large, the interval distance between the first antenna 310 and the second antenna 320 is large, so that the first antenna 310 and the second antenna 320 are difficult to be integrated and installed. When the distance N is small, the interval distance between the first antenna 310 and the second antenna 320 is small, so that a large interference is generated between the first antenna 310 and the second antenna 320. Therefore, the distance N should be moderate, so that a small interference is generated between the first antenna 310 and the second antenna 320, and the first antenna 310 and the second antenna 320 are easily integrated and installed. In some embodiments, the distance N satisfies: 1 cm≤N≤4 cm. For example, the distance N can be 1 cm, 2 cm, 3 cm, 4 cm, or the like, so as to ensure that the distance N is moderate, a small interference is generated between the first antenna 310 and the second antenna 320, and the first antenna 310 and the second antenna 320 are easily integrated and installed.

[0068] The device housing 100 includes a first recess 140, and the first recess 140 can have various structures. In some embodiments, the first recess 140 can be a cuboid. In other embodiments, the first recess 140 can be a cylinder. In other embodiments, the first recess 140 can be a polygon. The first opening 130 is arranged in the first recess 140, and the first recess 140 includes a third wall surface 150 parallel to the first wall surface 120. In some embodiments, the first opening 130 is arranged on the third wall surface 150. In a direction perpendicular to the first wall surface 120, a distance from the first wall surface 120 to the third wall surface 150 is M, as shown in FIG. 1. Figure 6It is to be noted that the distance between the first wall 120 and the third wall 150 is the distance between the center of the first wall 120 and the center of the third wall 150 in the direction perpendicular to the first wall 120. In some embodiments, the distance M satisfies: 0.5cm≤M≤1cm, and for example, M can be 0.5cm, 0.6cm, 0.7cm, 0.8cm, 0.9cm, 1.0cm, etc. By arranging the first opening 130 in the first groove 140, the signaling part 300 is further separated from other electronic parts in the signaling part 300, and the interference of the electrical signals generated by other electronic parts on the first antenna 310 and the second antenna 320 is further reduced, and the starting rate of the first antenna 310 and the second antenna 320 is further improved, and the use efficiency of both is further improved. It is to be noted that in some embodiments, the distance between the second wall 220 and the third wall 150 is L+M, and the distance L+M satisfies: 1.5cm≤L+M≤5cm, and for example, L+M can be 1.5cm, 2.0cm, 2.5cm, 3.0cm, 3.5cm, 4.0cm, 4.5cm, 5.0cm, etc.

[0069] In some embodiments, referring to Figure 5 The thickness of the protective cover 200 is A, and the thickness of the device housing 100 is B. Both the protective cover 200 and the device housing 100 are used to protect the components therein, but the protective cover 200 needs to receive or emit signals, while the device housing 100 does not. Therefore, in order to ensure signal transmission, the thickness A and the thickness B satisfy: A≤B. In some embodiments, the thickness A and the thickness B satisfy: 2A≤B.

[0070] Referring to Figure 4 The protective cover 200 includes a partition device 230 arranged in the second inner cavity 210 to divide the second inner cavity 210 into two sub-inner cavities, and the first antenna 310 and the second antenna 320 are arranged in the sub-inner cavities, respectively. By further dividing the second inner cavity 210 by the partition device 230, the distance between the first antenna 310 and the second antenna 320 is further increased, the mutual interference between signals is further reduced, the starting rate of the first antenna 310 and the second antenna 320 is further improved, and the use efficiency of both is further improved.

[0071] In some embodiments, the protective cover 200 and the device housing 100 are connected by threads, so that the protective cover 200 is configured to be quickly disassembled. In other embodiments, the protective cover 200 and the transmitting unit 300 are connected by threads, so that the protective cover 200 is configured to be quickly disassembled. In other embodiments, the transmitting unit 300 and the device housing 100 are connected by threads, so that the transmitting unit 300 is configured to be quickly disassembled. By allowing the protective cover 200, the transmitting unit 300 and the device housing 100 to be quickly disassembled, the interval between the first antenna 310 and the second antenna 320 can be quickly installed and adjusted to ensure that the first antenna 310 and the second antenna 320 start up faster.
