Description

Technical Field

[0001] This utility model relates to the field of emergency broadcasting equipment technology, and in particular to a CDR emergency broadcasting Bluetooth speaker housing gap design structure that facilitates heat dissipation. Background Technology

[0002] As an important part of the public safety and emergency management system, CDR emergency broadcast Bluetooth speakers are usually deployed in scenarios that require long-term, high-volume continuous playback of instructions or information. Under such high-load working mode, the internal power amplifier, main control chip and other core electronic components will continuously generate a lot of heat. In order to ensure portability and a certain degree of protection, most existing Bluetooth speakers adopt a compact structure and a relatively sealed shell design. The heat dissipation method generally relies on the natural heat conduction of the shell itself and some fixed, limited-size heat dissipation holes for passive air convection. This design can meet the heat dissipation needs when used intermittently in daily life.

[0003] However, in demanding applications such as emergency broadcasting that require continuous high-power output, the efficiency of the aforementioned passive heat dissipation structure becomes inadequate. A large amount of heat accumulates rapidly inside the compact casing and cannot be dissipated in a timely and effective manner, causing the internal temperature of the equipment to rise sharply. This overheating not only accelerates the aging of components and reduces the service life of the equipment, but also causes unstable phenomena such as sound distortion, system lag, or even crashes in the speakers, seriously affecting the reliability and timeliness of emergency command transmission and posing a safety hazard.

[0004] Therefore, this utility model proposes a gap design structure for the CDR emergency broadcast Bluetooth speaker housing to facilitate heat dissipation, thereby addressing the shortcomings of the prior art. Utility Model Content

[0005] In view of the problem that in the existing technology, emergency broadcast Bluetooth speakers, under long-term high-load working mode, have a large amount of heat accumulation that cannot be effectively dissipated due to their compact internal structure and passive and single heat dissipation method, which affects the stability and reliability of the equipment operation, this utility model aims to provide a CDR emergency broadcast Bluetooth speaker shell gap design structure with improved structure that can effectively solve the above problems and facilitate heat dissipation.

[0006] This utility model provides a gap design structure for the housing of a CDR emergency broadcast Bluetooth speaker that facilitates heat dissipation, including: a fixed housing, a gap mechanism disposed inside the fixed housing, and a heat dissipation component installed at the rear of the fixed housing.

[0007] The gap mechanism is the core innovative structure of this utility model, including a fixed frame and an adjustment component for adjusting the vertical position of the fixed frame inside the fixed shell. The adjustment component can actively change the internal structural space of the speaker to optimize the heat dissipation channel.

[0008] Furthermore, the adjustment assembly includes an electric push rod, a connecting plate, a pawl, and a ratchet. These components are combined in the following way: the output end of the electric push rod is movably connected to the fixed frame via the connecting plate to drive the fixed frame to move up and down; a ratchet is fixed on the inner wall of the fixed housing; and a pawl that can mesh with the ratchet is fixed on the connecting plate. Through the one-way locking engagement between the ratchet and the pawl, the position of the fixed frame after adjustment is precisely locked, thus forming a stable, reliable, and actively adjustable internal clearance structure.

[0009] Preferably, the structure of the heat dissipation component is further optimized, including a connecting frame fixed to the rear of the fixed shell, a fan and a heat sink installed inside the connecting frame, a ventilation frame provided on the connecting frame, and multiple air guide plates rotatably connected inside the ventilation frame. These air guide plates are connected by connecting rods to ensure synchronous rotation to guide airflow. A protective shell is also provided on the outermost side of the entire heat dissipation component to protect the internal components.

[0010] Preferably, in order to improve the stability and protective performance of the gap mechanism, the inside of the fixing frame is inlaid with a filling frame that plays a shock-absorbing and buffering role, and the outside of the filling frame is covered with a mesh to prevent external dust from entering.

[0011] Preferably, as a specific implementation, the inside of the mounting frame is also fixedly connected to an arc-shaped frame with a hollow structure. A funnel for assisting sound conduction is fixed at the inner opening of the arc-shaped frame. This design is conducive to air circulation and also takes into account the sound-producing function of the speaker.

[0012] Preferably, in order to reduce vibration and noise during equipment operation, a shim that provides sound insulation and shock absorption is rotatably connected between the bottom of the fixed frame and the inner bottom surface of the fixed shell.

[0013] Preferably, to improve the ease of user operation, the top surface of the fixed shell is provided with buttons and a display screen, and the buttons and display screen are integrated on the same operation panel.

[0014] Preferably, in order to ensure signal reception and data transmission capabilities, the rear of the fixed housing is also provided with a rotatable and adjustable antenna and multiple jacks for data connection.

[0015] Preferably, the pawl in the adjusting assembly is an elastic element. This design allows it to smoothly skip over the teeth of the ratchet in one direction when the electric push rod moves the connecting plate, and reliably engage with the teeth of the ratchet when locking is required, thereby achieving a stable and reliable one-way locking function.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem of overheating caused by the single and inefficient heat dissipation method of existing emergency speakers by setting an adjustable internal space gap mechanism and an active exhaust heat dissipation component to work together. It achieves a dual heat dissipation effect that combines internal air convection and external forced ventilation, which significantly improves the heat dissipation performance of the equipment and ensures its operational stability under long-term high-load operation.

[0018] 2. This utility model uses an adjustment component driven by an electric push rod and locked by a ratchet and pawl mechanism to control the internal gap, which solves the problem that the traditional speaker structure is fixed and cannot dynamically adjust the heat dissipation space according to the heat load of the equipment. It achieves flexible and variable heat dissipation space while ensuring the stable self-locking of the adjusted structure, thereby improving the reliability and safety of the equipment operation.

[0019] 3. This utility model solves the problems of disordered airflow and uneven heat dissipation in traditional fan cooling by setting multiple guide plates in the heat dissipation component that are linked by connecting rods to achieve synchronous rotation. It effectively guides and evenly diffuses the exhaust hot air, improves the efficiency of active heat dissipation, and avoids local heat accumulation at the air outlet. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 5 This utility model provides a CDR emergency broadcast Bluetooth speaker housing gap design structure that facilitates heat dissipation. It aims to solve the problem that existing emergency broadcast Bluetooth speakers accumulate internal heat during long-term operation, which is difficult to dissipate and thus affects the stability of device operation.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the CDR emergency broadcast Bluetooth speaker housing gap design structure for easy heat dissipation includes a fixed shell 1, a gap mechanism 2 disposed inside the fixed shell 1, and a heat dissipation component 3 installed at the rear of the fixed shell 1. The core function of the gap mechanism 2 is to change its own structural space through an adjustment component 207, thereby adjusting the internal airflow channel. The gap mechanism 2 includes a fixed frame 204 and an adjustment component 207 for adjusting the vertical position of the fixed frame 204 inside the fixed shell 1. More specifically, the adjustment component 207 includes an electric push rod 2074, a connecting plate 2071, a pawl 2073, and a ratchet 2072. The output end of the electric push rod 2074 is movably connected to the fixed frame 204 through the connecting plate 2071 to drive the fixed frame 204 to generate displacement. The ratchet 2072 is fixedly connected to the inner wall of the fixed shell 1, and the upper side of the connecting plate 2071 is fixedly connected to... The device includes a pawl 2073 that meshes with the ratchet 2072. During operation, the electric push rod 2074 serves as the power source, and its extension and retraction are directly transmitted to the fixed frame 204 via the connecting plate 2071. This causes the entire fixed frame 204 to move vertically within the fixed housing 1, thereby changing the space between the gap mechanism 2 and the fixed housing 1. The ratchet 2072 and the pawl 2073 together form a self-locking mechanism. The pawl 2073 is an elastic element. When the electric push rod 2074 pushes the connecting plate 2071, the pawl 2073 can unidirectionally skip over the teeth of the ratchet 2072. Under the action of the reverse force, the pawl 2073 will immediately mesh with the teeth of the ratchet 2072, thereby achieving a unidirectional locking function for the fixed frame 204 at any adjustable position. This effectively prevents the frame from sliding due to equipment vibration or its own gravity, ensuring the stability and reliability of the gap adjustment.

[0031] Including heat dissipation component 3; please refer to the following carefully. Figure 2 , Figure 3 and Figure 5 The heat dissipation assembly 3 is fixed to the rear of the fixed housing 1, including a connecting frame 301 fixed to the rear of the fixed housing 1. The connecting frame 301 is equipped with a fan 302 for active heat dissipation and a heat dissipation plate 304 for auxiliary heat conduction. In order to optimize the airflow discharged by the fan 302, a ventilation frame 307 is also provided on the connecting frame 301. Multiple guide plates 305 are rotatably connected inside the ventilation frame 307. The multiple guide plates 305 are connected by a connecting rod 306 to ensure that all guide plates 305 can rotate synchronously under the action of airflow, so as to effectively guide and diffuse the discharged hot air. A protective housing 303 is also provided on the outermost side of the heat dissipation assembly 3. The protective housing 303 provides structural protection for the internal components such as the fan 302 and the guide plates 305, enhancing the operational stability and durability of the entire heat dissipation assembly 3.

[0032] As a preferred implementation method, please refer to Figure 3 and Figure 4In order to further stabilize the internal structure of the gap mechanism 2 and play a role in shock absorption and buffering, the inside of the fixing frame 204 is inlaid with a filling frame 201, and a layer of mesh 203 is wrapped on the outside of the filling frame 201. The mesh 203 can effectively prevent external dust or debris from entering the interior of the gap mechanism 2.

[0033] As a preferred implementation method, please refer to Figure 4 In order to optimize the speaker's sound-producing structure and assist in heat dissipation, a hollow arc-shaped frame 206 is fixedly connected inside the mounting bracket 204, and a funnel 202 for assisting sound conduction is fixedly connected to the inner opening of the arc-shaped frame 206.

[0034] As a preferred implementation method, please refer to Figure 3 In order to achieve sound insulation and vibration reduction, a gasket 205 is rotatably connected between the bottom of the fixing frame 204 and the inner bottom surface of the fixing shell 1.

[0035] As a more preferred implementation method, please refer to Figure 1 and Figure 2 To facilitate user operation and information interaction, the top surface of the fixed housing 1 is provided with operation buttons 4 and display screen 5 for displaying information. The buttons 4 and display screen 5 are integrated on the same operation panel. At the same time, the rear of the fixed housing 1 is also provided with an antenna 6 that can be rotated and adjusted to enhance signal reception capability, as well as multiple jacks 7 for data connection.

[0036] Working principle: When the emergency broadcast Bluetooth speaker needs efficient heat dissipation, the internal adjustment component 207 starts working. Specifically, the electric push rod 2074 is activated, pushing the connecting plate 2071 to move. Since the connecting plate 2071 is movably connected to the fixing frame 204, the fixing frame 204 moves vertically inside the fixing shell 1, thereby increasing the internal space between the gap mechanism 2 and the fixing shell 1, forming an efficient air convection channel. During this process, the pawl 2073 fixed on the connecting plate 2071 slides over the teeth of the ratchet 2072 fixed on the inner wall of the fixing shell 1. Once the adjustment is in place, the pawl 2073 engages and locks with the ratchet 2072, thereby stabilizing the fixing frame 204 in the new position and ensuring the continuous effectiveness of the heat dissipation gap.

[0037] To further enhance heat dissipation, the heat dissipation component 3 installed at the rear of the fixed housing 1 works in concert. The internal fan 302 rotates at high speed, forcibly extracting the heat accumulated inside the gap mechanism 2 through air convection and discharging it to the outside. When the discharged hot airflow passes through the ventilation frame 307, it drives multiple internal guide plates 305 to rotate. Through the action of the connecting rod 306, all guide plates 305 rotate synchronously. This design can effectively guide and diffuse the discharged hot air, avoiding local heat accumulation at the rear of the equipment. Thus, through the dual action of internal gap adjustment and external active ventilation, the heat dissipation problem caused by long-term operation of the equipment is solved.
