Description

Technical Field

[0001] This utility model relates to the field of smartwatch technology, specifically to a bottom cover for a smartwatch. Background Technology

[0002] A smartwatch is a watch with a built-in intelligent system and a smartphone operating system that connects to the network to achieve multiple functions. It can synchronize calls, text messages, emails, photos, music, etc. from the phone, and also has the function of recording physical health status.

[0003] Chinese Patent No. CN217982144U discloses a bottom cover for a smartwatch and the smartwatch itself. The smartwatch includes a top cover, a PCBA board, a speaker, a microphone, and a motor. It includes: a first accommodating cavity for mounting the speaker, located inside the bottom cover body; and a second accommodating cavity for mounting the motor, also located inside the bottom cover body. The first and second accommodating cavities are located at either corner of the bottom cover. The bottom cover has at least one sound outlet hole connecting the first accommodating cavity to the outside. By setting the first accommodating cavity for mounting the speaker and the second accommodating cavity for mounting the motor at one corner of the bottom cover, the speaker and motor can be directly placed in the first and second accommodating cavities during installation, reducing the soldering process between the speaker and motor and the PCBA board pads. Using the aforementioned bottom cover for the smartwatch reduces the soldering and assembly process for components such as the speaker and motor, saving time and costs and improving production efficiency.

[0004] However, the above technical solutions have the following shortcomings: the base of existing watches is usually a smooth flat surface. This structure causes the skin of the wrist that is in close contact with the base to be isolated from the air. Therefore, the sweat excreted from the pores cannot evaporate, which can make people feel very uncomfortable, especially in the hot summer. At the same time, this increases the moisture in the wrist joint and also affects health. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a bottom cover for a smartwatch.

[0006] The technical solution of this utility model: a bottom cover for a smartwatch, comprising:

[0007] The mounting plate has a support cylinder fixedly connected to its surface. The watch body is detachably connected to the mounting plate. The support cylinder has ventilation holes through it.

[0008] A vent plate is located inside the support cylinder, and a heat dissipation cavity is formed between the vent plate and the watch body for heat dissipation between the watch body and the wrist.

[0009] The watch has multiple locking mechanisms, one end of which is connected to the support cylinder and the other end is connected to the watch body.

[0010] The convection mechanism is located on one side of the support cylinder and is connected to the support cylinder to accelerate the flow of air between the support cylinder and the outside air.

[0011] Preferably, the support cylinder is provided with multiple support plates, one end of which is connected to the mounting plate and the other end of which is connected to the vent plate, forming an airflow channel between the support plates.

[0012] Preferably, each set of locking mechanisms includes a mounting box, a connecting rod, a limiting block, and a locking block; the mounting box is fixedly connected to the support cylinder, one end of the connecting rod is located inside the mounting box, the other end of the connecting rod extends outside the mounting box, the connecting rod is rotatably connected to the mounting box, the locking block is located outside the mounting box and is fixedly connected to the connecting rod, and the limiting block is connected to the watch body.

[0013] Preferably, it also includes a return spring and an adjusting block; the return spring is disposed inside the mounting box, one end of the return spring is fixedly connected to the inner wall of the mounting box, the other end of the return spring is fixedly connected to the connecting rod, one end of the adjusting block is fixedly connected to the connecting rod, and the other end of the adjusting block extends to the outside of the mounting box.

[0014] Preferably, the convection mechanism includes a mounting cylinder, a mounting frame, and a cooling fan; the mounting cylinder is connected to the support cylinder, the mounting frame is disposed inside the mounting cylinder, and the cooling fan is fixedly connected to the mounting cylinder through the mounting frame.

[0015] Preferably, a limiting rod is fixedly connected to the surface of the support cylinder, and a limiting groove adapted to the limiting rod is opened on the surface of the watch body, with the limiting rod and the limiting groove being slidably connected.

[0016] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0017] This invention, through the design of a convection mechanism, a support cylinder, and a vent plate, creates a heat dissipation channel between the wearer's wrist and the smartwatch. When it is necessary to accelerate the heat exchange efficiency of the heat dissipation channel, the cooling fan operates to send air from around the watch into the support cylinder through the mounting cylinder. The air then passes through the airflow channel within the support cylinder and is discharged through the ventilation holes, effectively accelerating the airflow within the heat dissipation cavity and thus improving heat exchange efficiency. This prevents the bottom of the watch from becoming damp due to the accumulation of sweat, thereby improving wrist comfort when wearing the watch and also benefiting wrist health.

[0025] like Figures 1-5 As shown, the bottom cover of a smartwatch proposed in this utility model includes a mounting plate 1, a vent plate 7, a snap-fit ​​mechanism, and a convection mechanism.

[0026] A support cylinder 2 is fixedly connected to the surface of the mounting plate 1. The watch body 5 is detachably connected to the mounting plate 1. A ventilation hole 6 is opened through the support cylinder 2. A sealing ring is provided on the other side of the mounting plate 1 for sealing with the watch body 5. A limit rod 9 is fixedly connected to the surface of the support cylinder 2. A limit groove 10 adapted to the limit rod 9 is opened on the surface of the watch body 5. The limit rod 9 and the limit groove 10 are slidably connected. Multiple support plates 8 are provided inside the support cylinder 2. One end of the support plate 8 is connected to the mounting plate 1, and the other end of the support plate 8 is connected to the vent plate 7. An airflow channel is formed between the support plates 8.

[0027] The vent plate 7 is located inside the support cylinder 2, and a heat dissipation cavity is formed between the vent plate 7 and the watch body 5 for heat dissipation between the watch body and the wrist.

[0028] Multiple locking mechanisms are provided. One end of the locking mechanism is connected to the support cylinder 2, and the other end of the locking mechanism is connected to the watch body 5.

[0029] The convection mechanism is located on one side of the support cylinder 2. The convection mechanism is connected to the support cylinder 2 to accelerate the airflow between the support cylinder 2 and the outside air.
