Description

Technical Field

[0001] This invention relates to the field of solar sunshade technology, and more specifically to a hand-cranked solar sunshade shell that integrates sound playback and charging functions. Background Technology

[0002] The hand-cranked housing is a key component of the hand-cranked lifting mechanism of a solar sun umbrella. It is used to protect the internal mechanical structure and enable the height adjustment of the umbrella surface. Modern solar sun umbrella hand-cranked housings have evolved into a variety of multi-functional designs, not limited to basic lifting functions, but integrating innovative features such as energy management and additional accessories.

[0003] The most common type is the hand-cranked umbrella with integrated energy control and management. For example, Chinese Patent CN222764881U, filed by our company on June 7, 2022, and authorized on April 18, 2025, discloses a novel solar-powered sunshade umbrella. It includes an umbrella body and a solar cell assembly. The umbrella body includes a column with a hand-cranked mechanism, umbrella ribs with LED lights, and an umbrella canopy. The solar cell assembly includes a solar panel mounted on a disc on the umbrella ribs, a battery, and a charge / discharge control unit. The LED lights, solar panel, and battery are all electrically connected to the charge / discharge control unit. Next, the hand crank housing and the column form a closed storage space, in which the battery and the charge / discharge control unit are built. The charge / discharge control unit includes a charge / discharge circuit board, as well as a power switch and a DC charging connector electrically connected to the charge / discharge circuit board. The power switch and the DC charging connector extend outward through the hand crank housing. The LED light group, solar panel and battery are all electrically connected to the charge / discharge circuit board. This allows control and management of the solar panel's power conversion, so that the converted power is stored in the battery, realizing the rational use of energy, and also giving the hand crank housing the function of a portable power source.

[0004] However, the additional functions of the hand-cranked shell of the aforementioned solar sunshade are still relatively simple, only capable of generating, storing, and supplying electricity. It lacks linkage with other modules, and the user experience remains at a basic level. Furthermore, since solar sunshades are mostly used outdoors, outdoor users often need multiple functions such as sunshade, charging, and atmosphere creation. Therefore, it cannot cover the usage needs, resulting in weak commercial competitiveness of the configured solar sunshade. Summary of the Invention

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the purpose of simplifying the description and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation. Therefore, they should not be construed as limiting this utility model.

[0031] like Figure 1 , Figure 2 as well as Figures 5 to 8As shown, this utility model relates to a hand-cranked solar sunshade housing integrating sound playback and charging functions. It includes a hand-cranked housing body 1, a central controller 2, and a Bluetooth speaker 3. Similar to conventional hand-cranked housings, the hand-cranked housing body 1 is mounted on the umbrella pole 4. The outer wall of the hand-cranked housing body 1 has an installation area 101 and a sound-emitting area 101, both of which are connected to the interior of the hand-cranked housing. The sound-emitting area 101 has several sound holes. A spring probe 5 is provided in the installation area 101. A first control circuit board 6 is located inside the hand-cranked housing body 1. The spring probe 5 and the solar panel on the solar sunshade housing with the hand-cranked housing are electrically connected to the first control circuit board 6. A probe is provided on the outer wall of the central controller 2. The probe holder 7 matches the spring probe 5. The shape of the mounting area 101 matches the central controller 2, which is embedded in the mounting area 101. The probe holder 7 and the spring probe 5 are inserted into each other, forming a conductive path between the solar panel and the central controller 2, and allowing the central controller 2 to be removed from the mounting area 101. The Bluetooth speaker 3 is located inside the hand-cranked housing 1, specifically installed in a position opposite to the sound output area 101. When the Bluetooth speaker 3 is working, the sound waves can be transmitted in a straight line through the sound output hole to the external space, avoiding multiple reflections inside the hand-cranked housing that cause energy attenuation. The Bluetooth speaker 3 is electrically connected to the first control circuit board 6. The outer wall of the central controller 2 is provided with an operation panel 8 and a charging interface 9. The operation panel 8 is equipped with a speaker... The central controller 2 is equipped with a control switch 801 and an internal battery 10 and a second control circuit board 11. The probe socket 7, charging interface 9, audio control switch 801, and battery 10 are all electrically connected to the second control circuit board 11. When the central controller 2 is installed in the mounting area 101 of the hand-cranked housing 1, the solar panels of the solar-powered sunshade convert light energy into electrical energy and store it in the battery 10. The battery 10 continuously powers the Bluetooth speaker 3, ensuring its stable operation. Users can trigger commands via the audio control switch 801. These commands are transmitted via the second control circuit board 11 to the first control circuit board 6 inside the hand-cranked housing 1. The first control circuit board 6 then analyzes and drives the Bluetooth speaker 3 to operate. Users can use the solar-powered sunshade with the hand-cranked housing installed according to this invention. When the solar-powered sunshade is used for outdoor activities, the Bluetooth speaker 3 can establish a communication connection with Bluetooth-enabled communication devices such as mobile phones and tablets. Users can play music, podcasts, or e-books at any time, thus upgrading the sunshade into a mobile audio platform, adding atmosphere to outdoor activities and bringing users a more immersive smart entertainment experience. In addition, when the central controller 2 is removed from the installation area 101, users can connect the data cable to the charging port 9 and the mobile device that needs to be charged. The battery 10 charges the connected mobile device, allowing the central controller 2 to be used as a power source. This increases the extended functionality of the hand-cranked shell of this utility model, thus providing users with diversified functions such as sunshade, charging, and atmosphere creation when installed on the solar-powered sunshade.This significantly enhances the commercial competitiveness of the configured solar-powered sunshades.

[0032] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the operation panel 8 is also equipped with a power indicator light 802 and a power display switch 803. Both the power indicator light 802 and the power display switch 803 are electrically connected to the second control circuit board 11. In this utility model, there are four power indicator lights 802. The user can trigger a command through the power display switch 803, and the second control circuit board 11 will control the power indicator lights 802 to light up. The power indicator lights 802 enable the user to intuitively understand the current power of the battery 10, providing behavioral decision support for the user.

[0033] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the first control circuit board 6 is also electrically connected to the ambient light on the solar sunshade. The operation panel 8 is also equipped with a light control switch 804, which is electrically connected to the second control circuit board 11. The user can trigger a command through the light control switch 804. The command is transmitted through the second control circuit board 11 to the first control circuit board 6 inside the hand crank housing 1. The first control circuit board 6 interprets the command and makes the ambient light on the solar sunshade work. Since the hand crank housing is usually located at a lower position on the umbrella pole 4, the user can easily operate the ambient light with a natural hanging arm posture, avoiding fatigue from repeatedly raising the arm.

[0034] like Figure 2 , Figure 7 and Figure 8 As shown, the charging port 9 is located at the bottom of the central controller 2. The charging port 9 is covered with a dust cover 12, which completely covers the charging port 9 and hides it inside the central controller 2, thus achieving physical protection against accidental touch.

[0035] Furthermore, charging port 9 is a Type-C interface. Based on the non-polarity of the Type-C interface and its high-power fast charging characteristics, it is convenient for users to connect data cables to charge mobile devices and shorten the charging time, thereby improving charging efficiency.

[0036] like Figures 3 to 8 As shown, a first magnetic block 13 is provided on the bottom wall of the installation area 101, and a second magnetic block 14 is provided inside the central controller 2. The first magnetic block 13 and the second magnetic block 14 have opposite polarities and attract each other. That is to say, after the central controller 2 is embedded in the installation area 101, the fixing effect is strengthened by magnetic attraction. In this way, while ensuring the safety of preventing falling off, the ease of disassembly and assembly of the central controller 2 is retained, so that the user experience can be effectively improved.

[0037] like Figures 3 to 8 As shown, a center connector slot 101a and a side connector slot 101b are sequentially provided in the installation area 101. A center connector block 201 and a side connector block 202 are correspondingly formed on the back of the center controller 2. The center connector slot 101a is inserted into the center connector block 201, and the side connector slot 101b is inserted into the side connector block 202. In the inserted state, the inner wall of the center connector slot 101a abuts against the outer wall of the center connector block 201, and similarly, the inner wall of the side connector slot 101b... The spring probe 5 and the probe seat 7 are respectively disposed in the center connector 101a and the center connector block 201, and the first magnetic block 13 and the second magnetic block 14 are respectively disposed in the side connector 101b and the side connector block 202. This ensures the correct connection between the spring probe 5 and the probe seat 7, and ensures the correct adsorption of the first magnetic block 13 and the second magnetic block 14.

[0038] like Figures 3 to 8 As shown, there are two side connector slots 101b and two center connector slots 101a. The two side connector slots 101b are located on the upper and lower sides of the center connector slot 101a, and the two side connector blocks 202 are located on the upper and lower sides of the center connector block 201. It can be understood that there are also two sets of first magnetic blocks 13 and second magnetic blocks 14. The two sets of first magnetic blocks 13 are respectively set in the two center connector slots 101a, and the two sets of second magnetic blocks 14 are respectively set in the two center connector slots 101a. When the central controller 2 is installed in the mounting area 101, its positions near both ends will be attracted and fixed, thereby maintaining a balanced attraction state and strengthening the fixing effect.

[0039] like Figure 5 and Figure 6As shown, the hand-cranked housing body 1 includes a front housing 1a, a rear housing 1b, a hand crank 1c, and a lifting transmission component 1d. The front housing 1a has a first rod slot 103 and a second rod slot 104 at its top and bottom, respectively, and a first crank slot 108 on its side wall. The first rod slot 103, the second rod slot 104, and the first crank slot 1d are all semi-circular in shape. The mounting area 101 and the sound output area 101 are located on the front housing 1a. The rear housing 1b has a third rod slot 106 and a fourth rod slot 107 at its top and bottom, respectively, and a second crank slot 108 on its side wall. The third rod slot 106, the fourth rod slot 107, and the second crank slot 108... The handle slots 108 are also semi-circular in shape. The first rod slot 103 and the third rod slot 106 are connected to each other to form a circular upper rod slot. The second rod slot 104 and the fourth rod slot 107 are connected to each other to form a circular lower rod slot. When installed on a solar sunshade, it is sleeved on the umbrella rod 4 through the upper umbrella rod 4 slot and the lower umbrella rod 4 slot. The first crank slot and the second crank slot 108 are connected to each other to form a crank slot. The lifting transmission component 1d is located between the front housing 1a and the rear housing 1b. The hand crank 1c is rotatably connected between the first crank slot and the second crank slot 108. The hand crank 1c can rotate in the crank slot and is connected to the lifting transmission component 1d.

[0040] like Figure 7 and Figure 8 As shown, the central controller 2 includes a base plate 2a and a top cover 2b. Four buckles 203 are arranged in sequence around the circumference of the base plate 2a, and they are distributed in pairs on the left and right sides of the base plate 2a. Locking blocks 204 are formed on the inner wall of the top cover 2b. The buckles 203 are fastened to the locking blocks 204 to fix the top cover 2b to the base plate 2a. The operation panel 8 and the charging interface 9 are located on the top cover 2b. The first control circuit board 6 and the battery 10 are located between the base plate 2a and the top cover 2b.

[0041] Combination Figures 1 to 8The hand-cranked housing body 1 of this utility model is equipped with a Bluetooth speaker 3. The Bluetooth speaker 3 can establish a communication connection with communication devices with Bluetooth functionality such as mobile phones and tablets. Users can trigger commands through the speaker control switch 801 to make the Bluetooth speaker 3 run and play music, podcasts, or e-books at any time, thereby upgrading the installed solar sunshade into a mobile audio platform, adding atmosphere to outdoor activities and bringing users a more immersive smart entertainment experience. The central controller 2 on the hand-cranked housing body 1 is embedded in the installation area 101 and magnetically fixed, allowing it to be removed from the installation area 101. Users can... Connect the data cable to the charging port 9 to charge the mobile device using the internal battery 10, making it a power bank. Combined with the basic sunshade function of the solar sunshade, it can provide users with a wealth of extended functions. In addition, users can trigger a command through the power display switch 803 on the operation panel 8 of the central controller 2 to light up the power indicator 802, thereby knowing the current power of the battery 10. The power of the battery 10 is replenished by the solar panel on the solar sunshade. Furthermore, users can trigger a command through the light control switch 804 to easily control the ambient light on the solar sunshade with a natural hanging posture.

[0042] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
