[0093] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0094] According to the first aspect of the present application, reference Figures 1 to 9 , a switch device 100 is provided, including: a housing 110 , a circuit board 120 , a split body and a spring 140 .

[0095] The shell 110 is used to enclose a receiving space 110a that is open on opposite first and second sides. The circuit board 120 is configured to be enclosed on the first side of the receiving space 110a. The sealing body 130 is configured to be enclosed on the second side of the receiving space 110a. The spring 140 is arranged in the receiving space 110a and is located between the circuit board 120 and the sealing body 130 to apply a force to the sealing body 130 to keep it away from the circuit board 120.

[0096] Through the above technical solution, the circuit board 120 and the sealing body 130 can be used to complete the closure of the accommodating space 110a relative to the first side and the second side, so that the spring 140 is placed in the accommodating space 110a, and the assembly of the switch device 100 is completed. Moreover, due to the simple structure of the switch device 100, the overall size of the switch device 100 can be reduced, making the switch device 100 as a whole lighter and thinner.

[0097] The circuit board 120 of the present application is a single-sided circuit board 120 , and one side having a circuit structure is disposed toward the accommodation space 110 a .

[0098] In some embodiments, reference Figure 2 , the circuit board 120 is connected to the housing 110.

[0099] By connecting the circuit board 120 with the shell 110, the structure of the switch device 100 is further simplified. At this time, the circuit board 120 serves as a structure for enclosing the accommodating space 110a, which can reduce the thickness of the switch while also reducing the cost of opening the mold for the back cover and reducing one process, thereby reducing the overall assembly cost. This overcomes the technical problem that the switch device 100 in the prior art is provided with a back cover to seal the accommodating space 110a, and then the circuit board 120, micro switch and other components are installed in the accommodating space 110a, but the overall structure is complicated and the provision of the back cover increases the thickness of the switch device 100.

[0100] In some embodiments, reference Figure 2 The switch device 100 further includes: a mounting structure 150 .

[0101] By setting up the mounting structure 150 and locating the mounting structure 150 on the inner peripheral wall surface of the shell 110, the circuit board 120 is installed to the shell 110 to be enclosed on the first side of the accommodating space 110a. The mounting structure 150 is set on the inner peripheral wall surface of the shell 110, and the overall thickness of the switch device 100 does not increase.

[0102] In some embodiments, reference Figure 2 The mounting structure 150 is constructed as a protrusion on the inner peripheral wall of the shell 110.

[0103] By constructing the mounting structure 150 as a protrusion on the inner peripheral wall of the shell 110 , molding is convenient, and there is a gap between the protrusion and the shell 110 , and part of the circuit board 120 is located in the gap, so that the circuit board 120 can be connected to the shell 110 .

[0104] In some embodiments, reference Figure 2 , along the direction in which the package body 130 extends toward the circuit board 120 , the protrusion has an inclined guiding surface.

[0105] The protrusion has an inclined guide surface along the direction of the package body 130 extending toward the circuit board 120 , which can play a guiding role in the process of installing the circuit board 120 into the housing 110 , thereby improving the convenience of assembly.

[0106] In some embodiments, reference Figure 2 The switch device 100 further includes: a sealing structure (not shown in the figure).

[0107] The sealing structure is connected to the circuit board 120 and the shell 110 respectively. After the circuit board 120 is installed on the shell 110, the circuit board 120 and the shell 110 are connected using the sealing structure, which can ensure the sealing effect between the circuit board 120 and the shell 110 and prevent the circuit board 120 from getting damp.

[0108] In some embodiments, the sealing structure is constructed as adhesive, which is bonded between the circuit board 120 and the housing 110 and covers a side of the circuit board 120 away from the elastic sheet 140 .

[0109] By constructing the sealing structure as an adhesive, bonding it between the circuit board 120 and the shell 110 and covering the side of the circuit board 120 away from the spring 140, the waterproof and fixing effects between the two can be ensured, and the entire switch device 100 can support better waterproofness and support underwater push switches.

[0110] In some embodiments, the housing 110 further has a glue-filled surface (not shown in the figure).

[0111] The glue filling surface is used to fill the adhesive glue to the glue filling surface.

[0112] By providing a glue filling surface on the housing 110 , excessive glue filling can be avoided, which would cause the adhesive to overflow from the housing 110 , and increase in the thickness of the switch device 100 can be avoided.

[0113] In some embodiments, reference Figures 10 to 12 The spring piece 140 includes: a contact portion 141 .

[0114] The contact portion 141 is configured as a driving switch of the circuit board 120;

[0115] The sealing body 130 is subjected to a pressing force to apply a force to the spring 140 , so that the contact portion 141 moves along the direction of the pressing force to be electrically connected with the circuit board 120 .

[0116] Exemplarily, the spring piece 140 can serve to keep the sealing body 130 away from the circuit board 120, and can also serve as a driving switch for the circuit board 120. When the sealing body 130 is subjected to pressing force, a force is applied to the spring piece 140 so that the contact portion 141 can move along the direction of the pressing force to be electrically connected to the circuit board 120, thereby making the circuit of the circuit board 120 conductive.

[0117] It should be noted that the contact portion 141 of the spring 140 is mainly set corresponding to the PAD area on the circuit board 120, that is, the conductive part on the circuit board 120. When the contact portion 141 contacts the line on the circuit board 120, a loop is formed, current flows, and the switch device 100 works.

[0118] In some embodiments, when the spring piece 140 is in a natural state, the contact portion 141 and the circuit board 120 have a first preset distance.

[0119] When the spring 140 is in a natural state, the contact portion 141 and the circuit board 120 have a first preset distance. When a certain pressing force is applied, the contact portion 141 will come into contact with the circuit board 120 to avoid misconnection of the circuit due to accidental contact.

[0120] In some embodiments, reference Figures 10 to 12 The spring piece 140 also includes: a main body 142 .

[0121] The body 142 is connected to the circuit board 120;

[0122] The main body 142 applies a force to the package 130 to move it away from the circuit board 120 , and after the pressing force on the package 130 is cancelled, the package 130 can return to its original position under the force of the main body 142 , so as to be convenient for the next use.

[0123] In some embodiments, reference Figures 10 to 12 , along the direction in which the package body 130 extends toward the circuit board 120 , the contact portion 141 is recessed in the body 142 .

[0124] By recessing the contact portion 141 in the main body 142 along the direction in which the sealing body 130 extends toward the circuit board 120 , the contact portion 141 can be brought into contact with the circuit board 120 within a certain range of movement, which is convenient for operation.

[0125] In some embodiments, reference Figures 9 to 12 The spring 140 also includes: a pin 143 .

[0126] By setting the pin 143, and the pin 143 is insulated and connected to the circuit board 120, so that the main body 142 is connected to the circuit board 120, it is possible to ensure that the spring 140 is directly connected to the circuit board 120 on the basis of realizing the circuit conduction of the circuit board 120 only by using the contact portion 141, without the need for other components, thereby further simplifying the structure.

[0127] Exemplarily, the number of the pins 143 may be three, and a mounting hole 120 a may be opened on the circuit board 120 , and a portion of the pins 143 may extend into the mounting hole 120 a , and the pins 143 may be interference fit with the mounting hole 120 a .

[0128] In some embodiments, reference Figure 8 The housing 110 is provided with a vent hole 110b which allows the accommodating space 110a to communicate with the outside.

[0129] By providing a vent hole 110b on the shell 110 to connect the accommodating space 110a with the outside, the gas in the accommodating space 110a can be easily discharged from the accommodating space 110a, so that the sealing body 130 can smoothly apply force to the spring piece 140 and the spring piece 140 can smoothly apply force to the sealing body 130.

[0130] In some embodiments, reference Figure 3 The switch device 100 further includes: a waterproof and breathable structure 160 .

[0131] By providing a waterproof and breathable structure 160, and connecting the waterproof and breathable structure 160 to the shell 110, the waterproof and breathable structure 160 at least partially blocks the vent 110b, thereby ensuring that the air in the accommodating space 110a is dry, preventing the circuit board 120 from getting damp, and extending its service life.

[0132] In some embodiments, the waterproof breathable structure 160 is configured as a waterproof breathable membrane.

[0133] Exemplarily, the waterproof breathable membrane can be directly bonded to the housing 110 , and the waterproof breathable membrane is easy to obtain and replace.

[0134] In some embodiments, reference Figure 5 The switch device 100 further includes: a connecting structure 170 .

[0135] The connection structure 170 is disposed between the package body 130 and the circuit board 120 to limit the relative position between the package body 130 and the circuit board 120 .

[0136] The connection structure 170 can prevent the package body 130 from being too close to the circuit board 120 , thereby preventing the elastic sheet 140 from being over-pressed and thus causing the strength to be damaged.

[0137] In some embodiments, reference Figure 7 The connection structure 170 includes: a first connection interface 171 and a second connection interface.

[0138] The first connection interface 171 is located at one of the package body 130 and the circuit board 120 , and the second connection interface is located at the other of the package body 130 and the circuit board 120 .

[0139] The first connection interface 171 and the second connection interface have a second preset distance, and when the first connection interface 171 and the second connection interface are combined, the relative position between the sealing body 130 and the circuit board 120 is limited.

[0140] By providing the first connection interface 171 and the second connection interface, when the first connection interface 171 and the second connection interface are combined, the relative position between the package 130 and the circuit board 120 is limited to prevent the package 130 from being too close to the circuit board 120 .

[0141] For example, the first connection interface 171 may be configured on the package 130 , and the second connection interface may be configured on the circuit board 120 .

[0142] In some embodiments, along the direction in which the package body 130 extends toward the circuit board 120 , the connection interface on the package body 130 is protruded from the package body 130 .

[0143] Exemplarily, the first connection interface 171 is disposed protruding from the sealing body 130 , which can further ensure smooth connection between the sealing body 130 and the circuit board 120 .

[0144] Exemplarily, the first connection interface 171 can also be constructed as a cross protrusion, and the end face of the cross protrusion can be constructed as a plane to avoid damage to the circuit board 120 when it contacts the circuit board 120. The surface of the circuit board 120 can be used as the second connection interface. Of course, some block structures can also be set on the circuit board 120 as the second connection interface.

[0145] In some embodiments, reference Figure 4 The switch device 100 further includes: a driving structure 180 .

[0146] The driving structure 180 is located between the sealing body 130 and the elastic sheet 140 , wherein the driving structure 180 is adapted to the contact portion 141 of the elastic sheet 140 .

[0147] By providing the driving structure 180 , the driving structure 180 can directly act on the elastic sheet to achieve circuit conduction of the circuit board 120 .

[0148] In some embodiments, reference Figure 4 and Figure 7 The driving structure 180 includes: a first driving interface 181 and a second driving interface 182 .

[0149] The first driving interface 181 is located at one of the sealing body 130 and the elastic sheet 140 , and the second driving interface 182 is located at the other of the sealing body 130 and the elastic sheet 140 .

[0150] When the first drive interface 181 and the second drive interface 182 are combined, the sealing body 130 and the spring 140 generate an interaction force, which can make the sealing body 130 tend to move away from the circuit board 120 , or enable the sealing body 130 to better apply a force to the spring 140 .

[0151] The first driving interface 181 is disposed on the sealing body 130 , and the second driving interface 182 is disposed on the spring sheet 140 .

[0152] Exemplarily, the first drive interface 181 can be constructed as a cross protrusion, and the end face of the cross protrusion is constructed as a plane. When it contacts the spring clip 140, it avoids damage to the spring clip 140 and can increase the contact area between the sealing plate and the spring clip 140 to ensure the connection stability between the two. The surface of the spring clip 140 can be used as the second drive interface 182.

[0153] It should be noted that the first driving interface 181 and the first connecting interface 171 are constructed in the same structure to facilitate molding.

[0154] In some embodiments, along the direction in which the package 130 extends toward the circuit board 120 , the driving interface on the package 130 is protruded from the package 130 .

[0155] By protruding the second driving interface 182 on the sealing body 130 on the sealing body 130 , the sealing body 130 and the spring 140 are stably connected.

[0156] In some embodiments, the driving structure 180 is disposed on one side of the connecting structure 170 , wherein the connecting interface is disposed relative to the driving interface against the circuit board 120 along the axial direction in which the package 130 extends toward the circuit board 120 .

[0157] By disposing the driving structure 180 on one side of the connecting structure 170 and the first connecting interface 171 being disposed close to the circuit board 120 relative to the first driving interface 181, a stable combination of the first connecting interface 171 and the second connection of the circuit board 120 is ensured.

[0158] In some embodiments, reference Fig.10 The switch device 100 also includes: a cable 191.

[0159] The cable 191 is partially electrically connected to the circuit board 120 , and partially extends out of the accommodation space 110 a to be electrically connected to an external device.

[0160] Part of the cable 191 is electrically connected to the circuit board 120, and part of the cable 191 extends out of the passage space to be electrically connected to an external device.

[0161] Exemplarily, the end of the cable 191 is constructed as bare copper and penetrates into the circuit board 120 , and the cable 191 is fixed by soldering in the circuit surface direction of the circuit board 120 , thereby completing the assembly of the cable 191 and the circuit board 120 .

[0162] In some embodiments, the enclosure 130 further has a waterproof structure 192 .

[0163] The waterproof structure 192 is disposed on the package body 130 along a radial direction of the package body 130 extending toward the circuit board 120 , and is connected between the package body 130 and an external device.

[0164] The waterproof structure 192 is provided to achieve a waterproof effect.

[0165] In some embodiments, the waterproof structure 192 is configured as a waterproof ring.

[0166] A waterproof ring is arranged around the sealing body 130 to ensure a waterproof effect, and the waterproof ring is arranged to protrude from the surface of the sealing body 130 .

[0167] In some embodiments, the switch device 100 further includes a pressing member 193 .

[0168] The pressing member 193 is connected to the sealing body 130 , wherein, under the effect of the pressing force, the pressing member 193 applies the pressing force to the spring piece 140 through the sealing body 130 .

[0169] By providing the pressing member 193 , a pressing force can be applied to the sealing body 130 and the elastic sheet 140 through the pressing member 193 .

[0170] In some embodiments, the pressing member 193 has a pressing interface 1931 .

[0171] The pressing interface 1931 is adapted to the connection interface and the driving interface on the sealing body 130 , wherein when the pressing interface 1931 is combined with the connection interface and the driving interface, the relative position of the pressing member 193 with respect to the sealing body 130 is limited.

[0172] Exemplarily, the pressing interface 1931 can also be constructed as a cross protrusion, which is adapted to the first connection interface 171 and the first drive interface 181. A groove is set on the seal 130 corresponding to the first connection interface 171 and the first drive interface 181. The shape of the groove is adapted to the cross protrusion shape of the pressing interface 1931, so that the pressing interface 1931 can be inserted into the first connection interface 171 and the first drive interface 181, thereby completing the combination of the pressing interface 1931 with the first connection interface 171 and the first drive interface 181.

[0173] In some embodiments, the hardness of the pressing member 193 is greater than the hardness of the sealing body 130 ; and / or the hardness of the sealing body 130 is less than the hardness of the housing 110 .

[0174] By making the hardness of the pressing piece greater than the hardness of the sealing body 130 , the pressing force can be stably transmitted to the spring sheet 140 , and the sealing body 130 can also rebound quickly under the action of the spring sheet 140 .

[0175] By making the hardness of the sealing body 130 smaller than the hardness of the housing 110 , the housing 110 can be stably connected to the external device.

[0176] Exemplarily, the sealing body 130 can be set to a soft rubber material, the shell 110 can be set to a hard rubber material, and the button cap can also be set to a hard rubber. Then, the hardness of the first connection interface 171 and the first drive interface 181 are both relatively hard, and the pressing force is stably transmitted while facilitating the operator to obtain a better operating experience.

[0177] The hardness of the sealing body 130 is adjusted according to the actual switch design force.

[0178] After the switch device 100 is installed on the external device, the pressing member 193 of the switch device 100 will expose the external device for the operator to operate. At this time, the waterproof structure 192 can also prevent the circuit board 120 in the accommodating space 110a from getting wet.

[0179] It should be noted that the first connection interface 171 and the first drive interface 181 have the same structure and differ only in size, which reduces the difficulty of molding.

[0180] In the present application, the spring 140 can simultaneously play the role of the rebound pressing member 193 and the circuit conduction of the circuit board 120, and there is no need to set a larger micro switch in the accommodating space 110a, so that the corresponding function can be achieved. While reducing the structure of the switch device 100 to reduce costs, the thickness of the switch device 100 can also be reduced.

[0181] The switch device 100 in the present application can have a thickness of 8.4 mm (the stroke is 1.0 mm, and the smaller the stroke, the smaller the thickness of the switch). Under the condition of unchanged reliability, the thickness of the device is thinner.

[0182] According to a second aspect of the present application, a luggage box is provided, which is suitable for a vehicle 10 and includes the switch device 100 as described above.

[0183] The suitcase has all the beneficial effects of the switch device 100 described above, which will not be described in detail in this application.

[0184] Furthermore, the switch of the suitcase can be made thinner and lighter.

[0185] According to the third aspect of the present application, reference Fig.13, a vehicle 10 is provided, comprising a switch device 100 as above or a luggage box as above.

[0186] The vehicle 10 has all the beneficial effects of the switch device 100 described above, which will not be described in detail in this application.

[0187] The vehicle 10 has all the beneficial effects of the above-mentioned luggage box, which will not be described in detail in this application.

[0188] The vehicle 10 may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and this application does not make any specific limitation on this.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
