Description

Technical Field

[0001] The utility model relates to the technical field of car locks, in particular to a waterproof sound - emitting device and a car lock. Background Art

[0002] With the development of the country and the progress of society, cars, as a means of transportation, have become more and more common. Along with the increase in the number of cars, the parking space resources are tense and the supply - demand is unbalanced. In order to strengthen management, especially for some parking lots, especially roadside parking spaces, car locks are usually installed on parking spaces. Common car locks are in an unmanned management and automatic control mode. When there is no car parked, the car lock is in a closed state, which does not affect the normal passage of pedestrians. When a car drives into the parking space, the car lock automatically identifies and raises the lock to restrict the movement of the car. After the car owner scans the code and pays, the car lock closes and the car can leave.

[0003] A sound - emitting device is arranged inside the car lock. When the car lock is opened, the car owner scans the code and pays, the car lock is closed, or even when the car owner forcibly drives away from the parking space, the sound - emitting device will give a voice prompt or sound an alarm. Since the car lock is set outdoors, rainwater can easily damage the sound - emitting device. Therefore, it is crucial to design a waterproof sound - emitting device.

[0004] The structure of the existing sound - emitting device is as Figure 1 and Figure 2 shown. It includes a sound - emitting part 01, a mounting bracket 02, a cover plate 03 and a circuit board 04. The sound - emitting part 01 is installed on the mounting bracket 02 through a first sealant 05. The side of the mounting bracket 02 facing away from the sound - emitting part 01 is ultrasonically welded with a cover plate 03. The circuit board 04 is installed on the mounting bracket 02 and is located between the mounting bracket 02 and the cover plate 03. An outlet is formed between the mounting bracket 02 and the cover plate 03 for the cable 07 installed on the circuit board 04 to pass through, and a second sealant 06 is arranged at the outlet. The existing sound - emitting device forms a bracket with accommodation and support functions by ultrasonically welding the mounting bracket 02 and the cover plate 03 to be used for sealing and installing components such as the sound - emitting part 01 and the circuit board 04. The sealing structure and process are complex, the production cycle is long, and the cost is high. Content of the Utility Model

[0005] In order to overcome at least one of the above - mentioned defects of the prior art, the utility model provides a waterproof sound - emitting device, which has the characteristics of simple structure, short production cycle and low cost.

[0006] The technical solution adopted by the utility model to solve its problems is as follows:

[0007] A waterproof sound - emitting device includes: a sound - emitting body and a bracket. The bracket is provided with a receiving groove adapted to the sound - emitting body. The sound - emitting body is hermetically installed on the opening of the receiving groove, and the sound - emitting body and the bracket enclose to form a sealed cavity structure.

[0008] The waterproof sound - generating device provided by the utility model forms a sealed cavity structure by arranging a receiving groove adapted to the sound - generating body in the bracket and sealingly installing the sound - generating body on the opening of the receiving groove. Thus, the utility model realizes the integrated design of the bracket, significantly simplifies the structure and sealing process of the waterproof sound - generating device, has a short production cycle, and can effectively reduce the production cost of the sound - generating device.

[0009] Furthermore, the bracket is provided with a wire outlet, and the bracket is provided with a wiring groove outside the cavity structure. The receiving groove is communicated with the wiring groove through the wire outlet, so that the internal wire of the sound - generating body passes through the wire outlet and extends outside the cavity structure and into the wiring groove, and is electrically connected to the input end of the external input wire. A seal is provided between the internal wire of the sound - generating body and the bracket at the wire outlet, and seals are provided between the internal wire of the sound - generating body, the input end of the external input wire and the bracket in the wiring groove.

[0010] Thus, the utility model arranges the wiring groove outside the cavity structure, and the internal wire of the sound - generating body and the input end of the external input wire are electrically connected in the wiring groove outside the cavity structure, which has the characteristics of convenient and stable wiring.

[0011] Furthermore, the sound - generating body and the groove wall of the receiving groove are sealingly connected by a first sealant.

[0012] Thus, the sealing process of installing the sound - generating body on the bracket is simple, and the sealing installation between the sound - generating body and the bracket can be quickly completed.

[0013] Furthermore, a circuit board is installed in the wiring groove. The internal wire of the sound - generating body and the input end of the external input wire are both electrically connected to the circuit board. A second sealant is used to seal between the internal wire of the sound - generating body and the bracket at the wire outlet, and third sealants are used to seal between the internal wire of the sound - generating body, the input end of the external input wire and the bracket in the wiring groove, and the circuit board is completely sealed in the wiring groove by the third sealant.

[0014] Thus, the sealing of the sound - generating device is realized through sealants, the sealing structure and process are simple, the production cycle is short, and the production cost is low. Moreover, the setting of the circuit board not only makes the electrical connection between the internal wire and the external input wire more stable, but also can process the signals transmitted by the external input wire, such as amplification, filtering, etc., to improve the sound quality of the sound - generating device.

[0015] Furthermore, the second sealant and the third sealant are connected into an integral structure.

[0016] Thus, the sealing performance of the wire outlet and the wiring groove is further improved.

[0017] Furthermore, the wire outlet is opened on the side wall of the accommodation groove. The wiring groove is arranged outside the cavity structure of the bracket with its back facing the sounding body. The wire outlet includes a through hole and a wiring channel. A through hole is provided in the side wall of the accommodation groove corresponding to the position of the sounding body, and the wiring channel extends from the through hole to the wiring groove. The wiring channel communicates with the accommodation groove through the through hole. The input end of the external input wire is partially inserted into the wiring groove through a part of the wiring channel.

[0018] Thus, the volume of the sounding device is small, occupying little space and facilitating installation. Moreover, during the process of the internal wire of the sounding body extending to the wiring groove, it is sealed, achieving effective waterproofing for the internal wire of the sounding body. At the same time, the input end of the external input wire does not directly enter the wiring groove, but is connected to the end face of the bracket body provided with the wiring groove parallel to the bracket body after passing through a section of the wiring channel, making the connection between the input end of the external input wire and the internal wire more stable. And the input end of the external input wire is sealed by two sealing structures at the wiring groove and the wiring channel, providing better waterproofing.

[0019] Furthermore, the bracket includes a bracket body. The bracket body is provided with an accommodation groove adapted to the sounding body. The side wall of the end face of the bracket body provided with the accommodation groove extends outward to form an extension part. The wiring groove is arranged on the extension part, and the wire outlet penetrates through the side wall of the bracket body corresponding to the extension part, so that the internal wire of the sounding body passes through the wire outlet and penetrates out of the side wall of the bracket body and extends into the wiring groove.

[0020] Thus, during the process of the internal wire extending from the bracket body to the wiring groove, it does not need to be bent, and the internal wire is not easily damaged.

[0021] Furthermore, the wire outlet extends upward to the upper end face of the side wall of the bracket body, and the depth of the wiring groove is not less than the depth of the wire outlet.

[0022] Furthermore, the extension part is provided with a wire hole. The wire hole penetrates through the extension part and communicates with the wiring groove. The input end of the external input wire extends into the wiring groove through the wire hole, and the wire hole is hermetically arranged.

[0023] Thus, the external input wire does not directly access the wiring groove, but extends into the wiring groove after passing through the transition of the wire hole, making the sealed part of the external input wire longer and the electrical connection between the external input wire and the internal wire more stable.

[0024] Furthermore, in the direction perpendicular to the bottom surface of the wiring groove, the wire hole penetrates through the extension part and communicates with the wiring groove. The input end of the external input wire passes through the wire hole from the end face of the extension part facing away from the wiring groove and extends into the wiring groove.

[0025] Since the extension part extends beyond the bracket body and the bottom of the extension part is empty, it is convenient for the external input wire to penetrate and route. And due to the shielding of the extension part, the external input wire at the bottom is not easily touched and the connection is more stable.

[0026] Furthermore, the wire hole penetrates through the side wall of the extension part and communicates with the wiring groove, and the input end of the external input wire passes through the wire hole from the outer part of the extension part and extends into the wiring groove.

[0027] Therefore, when the external input wire is connected to the wiring groove, there is no need to bend it, and it is not easy to be damaged.

[0028] To sum up, the beneficial effects of the waterproof sound - generating device provided by the present utility model are as follows:

[0029] 1) By providing a receiving groove on the bracket that fits the sound - generating body and sealingly installing the sound - generating body on the opening of the receiving groove, a sealed cavity structure is formed by enclosing the sound - generating body and the bracket. Thus, the present utility model realizes the integrated design of the bracket, significantly simplifies the structure and sealing process of the waterproof sound - generating device, has a short production cycle, and can effectively reduce the production cost of the sound - generating device;

[0030] 2) The communication between the wire outlet and the wiring groove enables the internal wire of the sound - generating body to be sealed and covered by the second sealant and the third sealant when extending from the wire outlet to the wiring groove, and will not be exposed outside, realizing effective waterproofing of the internal wire of the sound - generating body;

[0031] 3) The provision of the extension part enables the internal wire of the sound - generating body to extend from the wire outlet to the wiring groove without reverse bending. The internal wire is not easy to be damaged and has good sealing performance;

[0032] 4) Installing a circuit board in the wiring groove can ensure that the external input wire and the internal wire are stably connected to the circuit board, making the electrical connection between the external input wire and the internal wire more stable. At the same time, the circuit board can also process the signal input by the external input wire to improve the sound quality of the sound - generating device; and the circuit board is completely sealed in the wiring groove by the third sealant, realizing effective waterproofing of the circuit board.

[0033] The present utility model also provides a parking lock, which includes a control mechanism and a waterproof sound - generating device. The waterproof sound - generating device is electrically connected to the control mechanism through an external input wire.

[0034] For the parking lock provided by the present utility model, by providing a waterproof sound - generating device with a simple structure, the space occupied by the sound - generating device in the parking lock is small, correspondingly reducing the volume of the parking lock. Moreover, the sound - generating device achieves effective waterproofing through a simple structure, which can ensure the normal voice broadcast and alarm of the parking lock, enabling people to timely understand the usage situation of the parking lock.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0051] A parking lock is a locking device installed on a parking space. Most parking lots, especially roadside parking spaces, are often equipped with parking locks to cope with the current situation of increasing car ownership and tight parking space resources. Common parking locks are in an unmanned management and automatic control mode. When there is no car parked, the parking lock is in a closed state, which does not affect the normal passage of pedestrians. When a car drives into the parking space, the parking lock automatically recognizes and raises the lock to restrict the movement of the car. After the car owner scans the code and pays, the parking lock closes and the car can leave.

[0052] A sound - emitting device is provided inside the parking lock. When the parking lock is opened, the car owner scans the code and pays, the parking lock closes, or even when the car owner forcibly drives away from the parking space, the sound - emitting device will give a voice prompt or sound an alarm. Since the parking lock is set outdoors, rainwater is very likely to damage the sound - emitting device. Therefore, it is crucial to design a waterproof sound - emitting device.

[0053] The structure of the existing sound - emitting device is as Figure 1 and Figure 2 shown. It includes a sound - emitting part 01, a mounting frame 02, a cover plate 03, and a circuit board 04. The sound - emitting part 01 is installed on the mounting frame 02 through a first sealant 05. The cover plate 03 is ultrasonically welded to the side of the mounting frame 02 facing away from the sound - emitting part 01. The circuit board 04 is installed on the mounting frame 02 and is located between the mounting frame 02 and the cover plate 03. An outlet is formed between the mounting frame 02 and the cover plate 03 for the cable 07 installed on the circuit board 04 to pass through, and a second sealant 06 is provided at the outlet. The existing sound - emitting device forms a bracket with accommodation and support functions by ultrasonically welding the mounting frame 02 and the cover plate 03 to be used for sealing and installing components such as the sound - emitting part 01 and the circuit board 04. The sealing structure and process are complex, the production cycle is long, and the cost is high.

[0054] Therefore, refer to Figure 3, the present utility model provides a waterproof sound - generating device, which includes a sound - generating body 1 and a bracket 2. The bracket 2 is provided with a receiving groove 231 adapted to the sound - generating body 1. The sound - generating body 1 is hermetically installed on the opening of the receiving groove. The sound - generating body 1 and the bracket 2 enclose to form a sealed cavity structure.

[0055] For the waterproof sound - generating device provided by the present utility model, by providing a receiving groove 231 in the bracket 2 that is adapted to the sound - generating body 1 and hermetically installing the sound - generating body 1 on the opening of the receiving groove 231, the sound - generating body 1 and the bracket 2 enclose to form a sealed cavity structure. Thus, the present utility model realizes the integrated design of the bracket 2, significantly simplifies the structure and sealing process of the waterproof sound - generating device, has a short production cycle, and can effectively reduce the production cost of the sound - generating device.

[0056] Refer to Figure 3 and Figure 4 , the bracket 2 is provided with an outlet 21. The bracket 2 is provided with a wiring groove 22 outside the cavity structure. The receiving groove 231 communicates with the wiring groove 22 via the outlet 21, so that the internal wire of the sound - generating body 1 passes through the outlet 21 to extend outside the cavity structure and into the wiring groove 22, and is electrically connected to the input end of the external input wire 3. A seal is provided between the internal wire of the sound - generating body 1 and the bracket 2 at the outlet 21, and seals are provided between the internal wire of the sound - generating body 1 and the input end of the external input wire 3 and the bracket 2 in the wiring groove 22.

[0057] Thus, for the waterproof sound - generating device provided by the present utility model, by providing a sealed wiring groove 22 and an outlet 21 on the bracket 2, the internal wire of the sound - generating body 1 is electrically connected to the external input wire 3 in the wiring groove 22 after passing through the outlet 21. Then, combined with the sealing structure at the outlet 21 and the sealing structure between the sound - generating body 1 and the bracket 2, effective waterproofing of the sound - generating device can be achieved. Moreover, the present utility model arranges the wiring groove 22 outside the cavity structure, and the internal wire of the sound - generating body 1 and the input end of the external input wire 3 are electrically connected in the wiring groove 22 outside the cavity structure, which has the characteristics of convenient and stable wiring.

[0058] Of course, in actual application, the wiring groove 22 may not be provided outside the cavity structure of the bracket 2, and the external input wire 3 can extend into the receiving groove 231 through the outlet 21 to be electrically connected to the internal wire of the sound - generating body 1. However, since the connection between the external input wire 3 and the internal wire is located in the receiving groove 231, it has the characteristic of inconvenient wiring.

[0059] It should be noted that there are various sound - generating devices on the market, such as speakers, audio systems, horns, etc. Which specific sound - generating device is used in the parking lock is determined by the manufacturer. In the present utility model, the sound - generating device is a speaker, refer to Figure 5, the sound generating body 1 includes a paper cone 11, a support frame 12 and a coil 13. The bracket 2 is provided with a receiving groove 231 adapted to the sound generating body 1. A magnet 232 is provided in the receiving groove 231, and the sound generating body 1 is hermetically installed on the opening of the receiving groove 231. Specifically, the support frame 12 extends into the receiving groove 213 and is installed on the magnet 232. The coil 13 is wound around the outer periphery of the support frame 12. The paper cone 11 is fixed to the support frame 12, and the paper cone 11 is hermetically installed on the opening of the receiving groove 231. When the external input wire 3 transmits an electrical signal to the sound generating device through the internal wire, the energy of the coil 13 interacts with the magnetic field of the magnet 232, causing the paper cone 11 to vibrate, so that the sound generating device emits sound.

[0060] In the present utility model, the paper cone 11 has a wavy structure, that is, the paper cone 11 is not in a straight and locked state, so that the vibration of the paper cone 11 can proceed smoothly.

[0061] On the basis of the above structure, the sound generating body 1 and the groove wall of the receiving groove 231 are hermetically connected by a first sealant 4. Thus, the sealing structure and the sealing process between the sound generating body 1 and the receiving groove 231 are simple, and the hermetic installation between the sound generating body 1 and the bracket 2 can be quickly completed.

[0062] A circuit board 7 is installed in the wiring groove 22. The internal wire of the sound generating body 1 and the input end of the external input wire 3 are both electrically connected to the circuit board 7. Between the internal wire of the sound generating body 1 and the bracket 2 at the wire outlet 21, it is sealed by a second sealant 5. Between the internal wire of the sound generating body 1, the input end of the external input wire 3 and the bracket 2 in the wiring groove 22, they are all sealed by a third sealant 6, and the circuit board 7 is completely sealed in the wiring groove 22 by the third sealant 6. Thus, the circuit board 7 and its electrical connection points with the internal wire of the sound generating body 1 and the input end of the external input wire 3 are all sealed by the third sealant to achieve a waterproof effect. The cooperation of the first sealant 4, the second sealant 5 and the third sealant 6 enables the sealing of the sound generating device to be completely achieved by the sealant. The sealing structure and the sealing process are simple, the production cycle is short, and the production cost is low. Moreover, installing the circuit board 7 in the wiring groove 22 can ensure that the external input wire 3 and the internal wire are stably connected to the circuit board 7, making the electrical connection between the external input wire 3 and the internal wire more stable. At the same time, the setting of the circuit board 7 can process the signal transmitted by the external input wire 3, such as amplification, filtering, etc., to improve the sound quality of the sound generating device.

[0063] Preferably, the second sealant 5 and the third sealant 6 are connected as an integral structure. Thus, there is no gap at the connection between the second sealant 5 and the third sealant 6, making the sealing performance of the wire outlet 21 and the wiring groove 22 better.

[0064] The above is the sealed installation structure of the sound-generating device. On this basis, theoretically, the outlet 21 and the wiring slot 22 can be opened at any position of the bracket 2, as long as the electrical connection between the inner wire and the outer input line 3 can be achieved. For example, the outlet 21 and the wiring slot 22 can be set on the end face of the bracket 2 with the receiving slot 231, can be set on the side wall of the bracket 2, can also be set on the end face of the bracket 2 facing away from the receiving slot 231, etc. In the present utility model, there are mainly two ways to set the outlet 21 and the wiring slot 22, which are described in detail below.

[0065] In a first embodiment, see Figure 3 and Figure 4 The wire outlet 21 is opened on the side wall of the receiving groove 231, and the wiring groove 22 is arranged outside the cavity structure of the bracket 2 with its back facing the sound body 1. The inner wire of the sound body 1 passes through the side wall of the receiving groove 231 through the wire outlet 21 and extends into the wiring groove 22 after being bent.

[0066] In this structure, the length of the bracket 2 only needs to be able to accommodate the sound-emitting body 1, and the wiring slot 22 and the outlet 21 will not increase the length of the bracket 2, so that the final assembled sound-emitting device is smaller in size, occupies less space, and the installation position is not easily restricted.

[0067] Specifically, see Figure 3 , Figure 4 and Figure 5 The wire outlet 21 includes a through hole 211 and a wiring channel 212. The side wall of the receiving groove 231 is provided with a through hole 211 corresponding to the position of the sound body 1. The wiring channel 212 is provided outside the cavity structure of the bracket 2, and the wiring channel 212 extends from the through hole 211 to the connecting wiring groove 22 away from the sound body 1. The wiring channel 212 is connected with the receiving groove 231 through the through hole 211. The inner wire of the sound body 1 passes through the receiving groove 231 through the through hole 211, passes through the first bend and extends along the wiring channel 212 away from the through hole 211, and then extends to the wiring groove 22 through the second bend. Therefore, when the inner wire of the sound body 1 extends to the wiring groove 22, it is sealed in the wiring channel 212, so as to prevent the inner wire from being exposed to the outside of the bracket 2 and being easily damaged.

[0068] The wiring groove 22 of the present utility model is arranged on the side wall of the bracket 2 near the wiring channel 212, and the position of the wiring groove 22 corresponds to the position of the wiring channel 212, and the wiring channel 212 and the wiring groove 22 are communicated. The wiring channel 212 penetrates through the side wall of the bracket 2 along its extending direction, the through hole 211 is arranged near the sounding body 1, the input end of the external input wire 3 is partially inserted into the wiring groove 22 through the wiring channel 212, and the input end of the external input wire 3 is arranged parallel to the end face of the bracket 2 provided with the wiring groove 22. Thus, the input end of the external input wire 3 does not directly enter the wiring groove 22 at an acute angle with the wiring groove 22, but is connected in parallel with the end face of the bracket 2 provided with the wiring groove 22 after passing through a section of the wiring channel 212, making the connection between the input end of the external input wire 3 and the inner wire more stable, and the input end of the external input wire 3 is sealed by two sealing structures at the wiring groove 22 and the wiring channel 212, with better waterproof performance.

[0069] Moreover, since the diameter of the external input wire 3 is larger than that of the inner wire, that is, the external input wire 3 is thicker than the inner wire, therefore, the width of the wiring channel 212 near the wiring groove 22 is larger than the width of the wiring channel 212 near the through hole 211. In this way, the variable diameter setting of the wiring channel 212 enables both the external input wire 3 and the inner wire to pass through the wiring channel 212 smoothly, and the width of the wiring channel 212 is set corresponding to the width of the wire, avoiding the inconvenience of sealing due to the over-wide wiring channel 212.

[0070] In the second embodiment, refer to Figure 6 and Figure 7 , the bracket 2 includes a bracket body 23, the bracket body 23 is provided with a receiving groove 231 adapted to the sounding body 1, the sounding body 1 is hermetically installed on the opening of the receiving groove 231 through the first sealant 4, and the sounding body 1 and the bracket body 23 enclose a closed cavity structure. The end face of the bracket body 23 provided with the receiving groove 231 extends beyond the side wall of the bracket body 23 to form an extension part 24, the wiring groove 22 is arranged on the extension part 24, and the wire outlet 21 penetrates through the side wall of the bracket body 23 corresponding to the extension part 24, so that the inner wire of the sounding body 1 passes through the wire outlet 21 and extends out of the side wall of the bracket body 23 and extends into the wiring groove 22. Thus, the inner wire does not need to be bent during the process of extending from the bracket body 23 to the wiring groove 22, and the inner wire is not easily damaged.

[0071] The wiring groove 22 of the present utility model extends to the side wall of the bracket body 23, so that the wire outlet 21 penetrating through the side wall of the bracket body 23 is directly communicated with the wiring groove 22. Thus, the inner wire can directly extend into the wiring groove 22 after passing through the bracket body 23, and in this path, the part where the inner wire passes through the bracket body 23 is completely sealed by the sealing structures at the wire outlet 21 and the wiring groove 22, with good waterproof effect.

[0072] Moreover, the wire outlet 21 extends upward to the upper end face of the side wall of the bracket body 23, and the depth of the wiring groove 22 is not less than that of the wire outlet 21. Thus, after the inner wire extends from the wire outlet 21 to the wiring groove 22, it can be completely sealed in the wiring groove 22 and will not be exposed outside the wiring groove 22.

[0073] Based on this structure, if the input end of the external input wire 3 directly extends into the wiring groove 22 at an acute angle with the wiring groove 22, only a small part of it is sealed in the wiring groove 22, and the sealing is not firm and is very easy to loosen. This not only affects the waterproof effect at the wiring groove 22, but also easily causes the electrical connection between the external input wire 3 and the inner wire of the sounding body 1 to be unstable, affecting the stable operation of the sounding device. Therefore, the extension part 24 of the present utility model is provided with a wire hole 241, the wire hole 241 penetrates through the extension part 24 and communicates with the wiring groove 22, and the input end of the external input wire 3 extends into the wiring groove 22 through the wire hole 241, and the wire hole 241 is hermetically arranged. Thus, the external input wire 3 does not directly access the wiring groove 22 at an acute angle with the wiring groove 22, but extends into the wiring groove 22 through the transition of the wire hole 241, so that the sealed part of the external input wire 3 is longer, and the electrical connection between the external input wire 3 and the inner wire is more stable.

[0074] Moreover, in this embodiment, the wire hole 241 is also sealed by the third sealant 6, that is, the third sealant 6 seals the wiring groove 22 and the wire hole 241 at the same time, thereby ensuring effective waterproofing of the input end of the external input wire 3.

[0075] Specifically, referring to Figure 6 , in the direction perpendicular to the bottom surface of the wiring groove 22, the wire hole 241 penetrates through the extension part 24 and communicates with the wiring groove 22, and the input end of the external input wire 3 passes through the wire hole 241 from the end face of the extension part 24 facing away from the wiring groove 22 and bends and extends into the wiring groove 22 to be electrically connected to the inner wire of the sounding body 1. Since the extension part 24 extends beyond the bracket body 23, with the end face provided with the wiring groove 22 as the upper surface, the lower part of the extension part 23 is empty, so that the external input wire 3 can be conveniently inserted and routed without being too messy, and due to the shielding of the extension part 24, the external input wire 3 is not easily touched and the connection is more stable.

[0076] Alternatively, the wire hole 241 penetrates through the side wall of the extension part 24 and communicates with the wiring groove 22, and the input end of the external input wire 3 passes through the wire hole 241 from the outer side part of the extension part 24 and directly extends into the wiring groove 22. Thus, the external input wire 3 does not need to be bent during the process of accessing the wiring groove 22 and is not easily damaged.

[0077] The above are two ways of setting the outlet 21 and the wiring slot 22 of the utility model. Regardless of the first embodiment or the second embodiment, the outlet 21 is sealed by the second sealant 5, and the wiring slot 22 is sealed by the third sealant 6. Therefore, the sealing of the sound-generating device is completely achieved by the sealant, and the sealing structure and sealing process are simple, the production cycle is short, and the production cost is low. In addition, in the second embodiment, the wire hole 241 is also sealed by the third sealant 6, that is, the third sealant 6 seals the wiring slot 22 and the wire hole 241 at the same time, thereby ensuring that the input end of the external input line 3 is effectively waterproof.

[0078] Also, see Figure 4 Regardless of the first embodiment or the second embodiment, hollow grooves 233 are provided at the four corners of the end of the bracket 2 of the utility model that is away from the accommodating groove 231 to reduce the weight of the sound-generating device and achieve lightweight of the sound-generating device.

[0079] In addition to the above waterproof sounding device, the utility model also provides a parking lock, see Figure 8 and Figure 9 The parking lock includes a control mechanism 20 and the waterproof sound-generating device 10 , and the waterproof sound-generating device 10 is electrically connected to the control mechanism 20 via an external input line 3 .

[0080] The parking lock also includes a flap 40 and a power mechanism 30, the power mechanism 30 is transmission-connected to the flap 40, and the power mechanism 40 and the waterproof sound-emitting device 10 are both electrically connected to the control mechanism 20. Thus, when a car is parked in the parking space, the control mechanism 20 controls the power mechanism 30 to drive the flap 40 to rotate and rise to prevent the car from leaving the parking space. After the car owner scans the code to pay, the control mechanism 20 controls the power mechanism 30 to drive the flap 40 to rotate in the opposite direction and fall, so that the car can leave the parking space. At the same time, the control mechanism 20 can also transmit a signal to the waterproof sound-emitting device 10 through the external input line 3, so that the waterproof sound-emitting device 10 issues a voice broadcast such as a successful payment. In addition, if the car owner forcibly leaves the parking space, the control mechanism 20 can also control the waterproof sound-emitting device 10 to sound an alarm.

[0081] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
