Technical Field

[0001] This utility model relates to the field of paging equipment technology, and in particular to a wireless paging device. Background Technology

[0002] Pagers are divided into wired and wireless types, with wireless pagers being the most widely used. Based on technology, wireless pagers can be categorized into frequency modulation (FM) and amplitude modulation (AM) technologies. Pagers are increasingly used in a wide range of industries, including catering, banking, government offices, supermarket chains, factories, construction sites, healthcare, and elderly care, and their functions are becoming increasingly diverse.

[0003] Wireless pagers typically require batteries to power them. To ensure long battery life, batteries need to be replaced regularly. However, in existing wireless pagers, the battery cover is usually connected by clips. These clips are prone to loosening due to deformation of the plastic parts, and the number of times they can be disassembled is limited. Repeated disassembly and deformation of the clips reduces the engagement amount and connection effectiveness, thus affecting the lifespan of the pager. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a wireless pager to solve the technical problem of the battery cover being easy to loosen in the prior art.

[0005] This utility model is achieved by the following technical solution: a wireless pager, including a housing, a motherboard, a storage battery, and a battery cover;

[0006] The bottom of the housing is provided with a sliding groove, which is arc-shaped and extends along the rotation direction of the battery cover. One end of the sliding groove has a slot, the diameter of which is larger than the diameter of the sliding groove.

[0007] The motherboard is disposed within the housing;

[0008] The energy storage battery is disposed inside the housing and is electrically connected to the motherboard;

[0009] The battery cover is rotatably disposed at the bottom of the housing. The battery cover is provided with an L-shaped snap-fit ​​part. The snap-fit ​​part can be inserted into / pulled out of the housing from the slot. After the snap-fit ​​part is rotated to the sliding groove, the snap-fit ​​part is snapped into the housing.

[0010] In one possible implementation, there are two of each of the sliding grooves and the locking parts, and the two sliding grooves and the two locking parts are arranged opposite to each other.

[0011] In one possible implementation, the snap-fit ​​portion is provided with a guide ramp, which is used to guide the snap-fit ​​portion to slide from the slot into the groove.

[0012] In one possible implementation, a snap-fit ​​protrusion is provided on the inner wall of the other end of the slide groove, and a snap-fit ​​groove corresponding to the snap-fit ​​protrusion is provided on the outer wall of the snap-fit ​​part. When the snap-fit ​​part is rotated at a certain angle, the snap-fit ​​protrusion extends into the snap-fit ​​groove.

[0013] In one possible implementation, the outer surface of the battery cover is provided with a first indicator corresponding to the snap-fit ​​portion, the outer surface of the housing is provided with a second indicator corresponding to the slot, and a third indicator corresponding to the snap-fit ​​protrusion.

[0014] In one possible implementation, a call button is provided on the top of the housing, and pressing the call button can trigger a call switch on the motherboard.

[0015] In one possible implementation, the housing has a battery compartment, the energy storage battery is disposed in the battery compartment, and the inner wall of the battery compartment has ribs that abut against the side wall of the energy storage battery.

[0016] In one possible implementation, the inner wall of the battery cover is provided with a support rib, which abuts against the lower end face of the energy storage battery.

[0017] In one possible implementation, the housing includes an upper shell and a lower shell, the upper shell and the lower shell being snap-fitted together.

[0018] In one possible implementation, the housing is provided with a hanging hole, which can be used to attach a hanging rope.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: the snap-fit ​​part cooperates with the sliding groove to make the battery cover and the housing rotate and snap-fit. Since the snap-fit ​​part can only be inserted into / pull out of the housing from the slot, when the user needs to open the battery cover, he / she only needs to rotate the battery cover to remove it, which is very convenient. Moreover, the snap-fit ​​part is more stable than the buckle and is not easy to loosen, which helps to improve the stability of the battery cover. Attached Figure Description

[0034] like Figure 1-6 The wireless pager shown includes a housing 1, a main board 2, a storage battery 3, and a battery cover 4. The bottom of the housing 1 is provided with a sliding groove 121, which is arc-shaped and extends along the rotation direction of the battery cover 4. One end of the sliding groove 121 has a slot 122, the diameter of which is larger than the diameter of the sliding groove 121. The main board 2 is disposed inside the housing 1. The storage battery 3 is disposed inside the housing 1 and is electrically connected to the main board 2. The battery cover 4 is rotatably disposed at the bottom of the housing 1. The battery cover 4 is provided with an L-shaped locking part 41, which can be inserted into / out of the housing 1 from the slot 122. After the locking part 41 rotates to the sliding groove 121, the locking part 41 engages with the housing 1. It should be noted that the motherboard 2 is equipped with a wireless communication module (either a Bluetooth module or a WIFI module). The pager connects wirelessly to the receiver (preferably a mobile phone, which can be controlled by an APP to emit a ringtone) through the wireless communication module. In addition, the motherboard 2 is also equipped with a button and an indicator light 21 for pairing with the receiver. The housing 1 is equipped with a pairing button 16 that can be pressed. When the pager needs to connect with the receiver, the pairing button 16 must be pressed to pair the motherboard 2 with the receiver. The indicator light 21 can indicate the current working status of the pager. Specifically, the latching part 41 is L-shaped, with the short arm of the latching part 41 perpendicular to the long arm. The long arm of the latching part 41 passes through the slide groove 121, and the long arm and the slide groove 121 are fitted with a gap to ensure the smooth sliding of the long arm. The diameter of the slot 122 is larger than the diameter of the slide groove 121, so that the short arm of the latching part 41 can only pass through the slot 122. After the short arm is inserted into the housing 1, rotating the battery cover 4 will latch the short arm with the housing 1, which is convenient and quick.

[0035] The beneficial effects of this utility model are as follows: the snap-fit ​​part 41 cooperates with the slide groove 121 to make the battery cover 4 rotate and snap-fit ​​with the housing 1. Since the snap-fit ​​part 41 can only be inserted into / out of the housing 1 from the slot 122, when the user needs to open the battery cover 4, he / she only needs to rotate the battery cover 4 to remove it, which is very convenient. Moreover, the snap-fit ​​part 41 is more stable than the buckle and is not easy to loosen, which helps to improve the stability of the battery cover 4.

[0036] Please refer to Figure 3 and Figure 4 In one possible implementation, there are two slides 121 and two snap-fit ​​parts 41, and the two slides 121 and the two snap-fit ​​parts 41 are arranged opposite to each other. It should be noted that the battery cover 4 is coaxially arranged with the housing 1, and the two slides 121 correspond one-to-one with the two snap-fit ​​parts 41. This design can further improve the connection strength and stability between the battery cover 4 and the housing 1.

[0037] Please refer to Figure 6 In one possible implementation, the engaging portion 41 is provided with a guide slope 411, which guides the engaging portion 41 to slide from the slot 122 into the slide groove 121. It should be noted that the guide slope 411 is located at one end of the lower surface of the short arm of the engaging portion 41. After the short arm extends from the slot 122, it needs to be rotated to the top of the slide groove 121. The guide slope 411 can prevent the end face of the short arm from contacting the end face of the inner wall of the slide groove 121, which helps to improve the smoothness of the sliding of the engaging portion 41.

[0038] Please refer to Figure 3 and Figure 4 In one possible implementation, the inner wall of the other end of the slide groove 121 is provided with a snap-fit ​​protrusion 123, and the outer wall of the snap-fit ​​part 41 is provided with a snap-fit ​​groove 412 corresponding to the snap-fit ​​protrusion 123. When the snap-fit ​​part 41 rotates at a certain angle, the snap-fit ​​protrusion 123 extends into the snap-fit ​​groove 412. It should be noted that the snap-fit ​​groove 412 is located on the long arm of the snap-fit ​​part 41. Since the long arm of the snap-fit ​​part 41 is in clearance fit with the slide groove 121, the snap-fit ​​protrusion 123 and the snap-fit ​​groove 412 cooperate to prevent the snap-fit ​​part 41 from sliding accidentally. Specifically, the outer wall surface of the snap-fit ​​protrusion 123 is arc-shaped, and the inner wall surface of the snap-fit ​​groove 412 is also arc-shaped. When the snap-fit ​​protrusion 123 extends into the snap-fit ​​groove 412, the two can fit together and fit together, and it is convenient for the snap-fit ​​protrusion 123 to enter and exit the snap-fit ​​groove 412. When the snap-fit ​​part 41 rotates to the limit position, the snap-fit ​​protrusion 123 extends into the snap-fit ​​groove 412. The cooperation between the snap-fit ​​protrusion 123 and the snap-fit ​​groove 412 can increase the friction, thereby preventing the battery cover 4 from rotating accidentally without external force, which greatly improves the stability of the battery cover 4.

[0039] Please refer to Figure 2In one possible implementation, the outer surface of the battery cover 4 is provided with a first indicator 42 corresponding to the snap-fit ​​portion 41, the outer surface of the housing 1 is provided with a second indicator 124 corresponding to the slot 122, and a third indicator 125 corresponding to the snap-fit ​​protrusion 123. It should be noted that when the first indicator 42 corresponds to the second indicator 124, it indicates that the snap-fit ​​portion 41 is located at the slot 122, and the battery cover 4 is in an openable state. When the first indicator 42 corresponds to the third indicator 125, it indicates that the snap-fit ​​groove 412 on the snap-fit ​​portion 41 corresponds to the snap-fit ​​protrusion 123, and the battery cover 4 is in a closed state. Specifically, the first indicator 42, the second indicator 124, and the third indicator 125 are small circular grooves or protrusions. In addition, the outer surface of the battery cover 4 also has a closed indicator arrow and an open indicator arrow arranged opposite to each other. The first indicator 42 is located in the middle of the closed indicator arrow and the open indicator arrow. The user only needs to rotate the battery cover 4 in the direction of the closed indicator arrow or the open indicator arrow to close or open the battery cover 4, which is convenient and quick.

[0040] Please refer to Figure 3 and Figure 5 In one possible implementation, a call button 13 is provided on the top of the housing 1. Pressing the call button 13 can trigger the call switch on the mainboard 2. It should be noted that the side wall of the call button 13 has two opposing elastic arms 131. The end of the elastic arm 131 is provided with a positioning hole 132. The inner wall of the housing 1 is provided with a positioning post 111 that cooperates with the positioning hole 132, so that the end of the elastic arm 131 is positioned on the positioning post 111. Thus, the call button 13 can be pressed and set on the housing 1. The user only needs to press the call button 13 to trigger the call switch on the mainboard 2, so that the mainboard 2 can communicate wirelessly with the receiver to achieve the purpose of calling.
