Description

Technical Field

[0001] This utility model relates to the field of vehicles, and more particularly to a power socket capable of detecting power plugs. Background Technology

[0002] Vehicles are generally equipped with an inverter system, which can convert the DC voltage of the battery into AC voltage and use the AC voltage to power the motor. Furthermore, the inverter system can also output the AC voltage to the conductive terminals inside the AC socket through cables, so that various electrical appliances that can be plugged into the AC socket can be used.

[0003] When the power plug is not plugged in, the conductive terminals inside existing AC sockets are usually in a live state, which may have the following defects:

[0004] On the one hand, the conductive terminals being energized may pose a safety hazard.

[0005] On the other hand, the conductive terminals consume a small amount of power, resulting in power loss.

[0006] To address these issues, some manufacturers have added a slider and a photoelectric sensor to the vehicle's power outlet. The force of the inserted power plug pushes the slider to the position of the photoelectric sensor, causing the sensor to generate a trigger signal. This trigger signal then activates the controller to energize the conductive terminals, ensuring that the terminals are energized only when the power plug is inserted, thus avoiding safety hazards and unnecessary power consumption.

[0007] However, this scheme requires a large number of sliding parts and photoelectric sensors, which correspond to the number of conductive terminals. This results in a greater number of parts being needed, which in turn requires more space and increases manufacturing costs.

[0008] Therefore, there is a need for further improvement of existing AC sockets.

[0009] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0052] It should be understood that the accompanying drawings are not necessarily drawn to scale, but rather present simplified representations of various features to illustrate the basic principles of this invention. The specific design features disclosed in this invention (including, for example, specific dimensions, orientations, positions, and shapes) will be determined in part by the specific application and environment in which they will be used.

[0053] Throughout these figures, the same reference numerals denote the same or equivalent parts of the present invention. Detailed Implementation

[0054] The present invention will now be described in detail with reference to various embodiments, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. Rather, the present invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit of the present invention and the scope defined by the appended claims.

[0055] When a component is described as being "above" or "on top of" another component, that component may be in contact with the other component, or there may be an intermediate component present.

[0056] The following is combined Figures 1 to 8 The present invention describes a power socket capable of detecting power plugs according to an embodiment of the present invention.

[0057] like Figure 1 and Figure 2 As shown, the power socket capable of detecting power plugs according to the embodiment of this utility model includes: a terminal support 100, two sets of conductive terminals 201 and 202, a slider 300, an elastic component 400, a circuit board assembly 500, a photoelectric sensor 600, and a controller 900.

[0058] like Figure 3 As shown, the terminal support 100 is provided with a first through groove 101 and extends toward a first side of the terminal support (i.e., Figures 1 to 4 The guide post 102 (on the upper side of the middle).

[0059] Two sets of conductive terminals 201 and 202 are mounted on the first side of the terminal support 100. The conductive terminals 201 and 202 have two or three through holes 203 for the power plug to pass through. The conductive terminals 201 and 202 are used to plug in the corresponding power plugs. The conductive terminals 201 and 202 can receive the AC voltage output from the inverter system and output the AC voltage to the power plug for use by related electrical appliances. The power plug includes a two-prong power plug 801 (see attached diagram). Figure 7Or a three-pronged power plug 802 (see below for compatibility). Figure 8 The power plug can pass through the through hole 203 of the conductive terminal and be electrically connected to the conductive terminal at the through hole 203.

[0060] The slider 300 is disposed between the conductive terminals 201 and 202 and the terminal support 100 and can slide along the guide post 102, such as Figure 4 As shown, the slider 300 includes a stop plate 301 and an extension plate 302 extending from the stop plate 301 toward the terminal support 100. A portion of the stop plate 301 extends below a through hole 203 of the conductive terminal 201, and another portion of the stop plate 301 extends below a through hole 203 of the conductive terminal 202.

[0061] The elastic component 400 is disposed between the slider 300 and the terminal support 100, and the elastic component 400 is used to reset the slider 300.

[0062] like Figure 5 As shown, the circuit board assembly 500 is disposed on the second side of the terminal support 100 (i.e., Figures 1 to 4 On the lower side of the circuit board assembly 500, a second through slot 501 is provided (see reference for details). Figure 5 The extension plate 302 of the slider 300 can pass through the first through slot 101 of the terminal support 100 and the second through slot 501 of the circuit board assembly 500.

[0063] The photoelectric sensor 600 is used to sense the extension plate 302 passing through the first through slot 101 and the second through slot 501, and can generate a trigger signal after sensing the extension plate 302.

[0064] The controller 900 is electrically connected to the photoelectric sensor 600, conductive terminal 201, and conductive terminal 202. The controller 900 can receive the trigger signal from the photoelectric sensor 600 and control the conductive terminals 201 and 202 to be energized according to the trigger signal. The controller 900 is installed in the vehicle body.

[0065] When the two-prong power plug 801 or the three-prong power plug 802 is inserted into a power socket capable of detecting the power plug, the sliding member 300, pushed by the two-prong power plug 801 or the three-prong power plug 802 passing through the conductive terminals, can overcome the elastic force of the elastic component 400 and move towards the circuit board assembly 500 (i.e., in...). Figures 1 to 5The slide member 300 moves downwards, so that the extension plate 302 of the slide member 300 passes through the first through slot 101 of the terminal support 100 and the second through slot 501 of the circuit board assembly 500, thereby causing the photoelectric sensor 600 to generate a trigger signal. The trigger signal can trigger the controller 900 to control the conductive terminal 201 and the conductive terminal 201 to be energized, so that the conductive terminal is energized only when the two-prong power plug 801 or the three-prong power plug 802 is inserted.

[0066] When the two-prong power plug 801 or the three-prong power plug 802 is unplugged from the power socket that can detect the power plug, the compressed elastic component 400 pushes the slider 300 to move away from the circuit board assembly 500 (i.e., reset), so that the photoelectric sensor 600 cannot sense the extension plate 302 of the slider 300 and cannot generate a trigger signal. As a result, the controller 900 controls the conductive terminals 201 and 202 to be de-energized because it does not receive a trigger signal, thereby avoiding safety hazards and unnecessary power consumption.

[0067] exist Figure 1 and Figure 2 In the implementation scheme, two sets of conductive terminals are provided, including conductive terminal 201 and conductive terminal 202. Among the conductive terminals, conductive terminal 201 can be inserted into a two-prong power plug 801, and conductive terminal 202 can be inserted into a three-prong power plug 802.

[0068] Two sets of conductive terminals correspond to one slider, and also to one photoelectric sensor 600, one first elastic element 401 (which will be introduced later), one second elastic element 402 (which will be introduced later), and one third elastic element 403 (which will be introduced later).

[0069] exist Figure 5 In the middle, conductive terminal 201 has two through holes 203, and conductive terminal 202 has three through holes 203.

[0070] In an exemplary implementation, such as Figure 3 As shown, the terminal support 100 includes a base plate 103. The base plate 103 is provided with a limiting plate assembly 104 corresponding to the sliding member 300. The limiting plate assembly 104 includes two parallel limiting plates 105 and 106. The limiting plate 105 extends from the base plate 103 toward the conductive terminals 201 and 202, and each limiting plate 105 is provided with a limiting groove 107. Figure 4 As shown, one end of the stop plate 301 of the sliding member 300 is provided with a boss 307 corresponding to the limiting groove 107.

[0071] The boss 307 at one end of the stop plate 301 of the sliding member 300 is inserted into the limiting groove 107 of the limiting plate 105 (see mating details). Figure 6The other end of the stop plate 301 of the slider 300 passes through the limiting groove 107 of another limiting plate 106 and extends to below one of the three through holes of the conductive terminal 202. Under the action of the limiting groove 107, the stop plate 301 of the slider 300 can always press the elastic component 400, thereby keeping the elastic component 400 in a compressed state and preventing the elastic component 400 from becoming misaligned when the vehicle moves due to loosening.

[0072] In an exemplary implementation, such as Figure 3 As shown, the first through groove 101 and the guide post 102 are disposed on the base plate 103.

[0073] In an exemplary implementation, such as Figure 5 As shown, the elastic component 400 includes a first elastic element 401, which is sleeved on the guide post 102 and abuts against the stop plate 301 and the base plate 103.

[0074] In an exemplary implementation, such as Figure 4 As shown, the slider 300 further includes an extension post 303 extending from the stop plate 301 toward the circuit board assembly 500, the extension post 303 being located between the limiting plate 105 and the limiting plate 106, as shown. Figure 5 As shown, the elastic component 400 further includes a second elastic member 402, which is sleeved on the extension post 303 and abuts against the stop plate 301 and the base plate 103.

[0075] In an exemplary implementation, such as Figure 4 As shown, the slider 300 further includes an extension post 304 extending from the stop plate 301 toward the circuit board assembly 500. The extension post 304 is located on the side of the limiting plate 106 away from the limiting plate 105, as shown. Figure 5 As shown, the elastic component 400 further includes a third elastic element 403, which is sleeved on the extension post 304 and abuts between the stop plate 301 and the base plate 103.

[0076] In an exemplary embodiment, the first elastic element 401, the second elastic element 402, and the third elastic element 403 may be springs. The types of the first elastic element 401, the second elastic element 402, and the third elastic element 403 are not limited thereto, and they may be any form in the prior art, as long as they can achieve the above-mentioned functions.

[0077] In an exemplary implementation, such as Figure 3 As shown, the base plate 103 is provided with a through guide hole 108 corresponding to the extension post 303 and a through guide hole 109 corresponding to the extension post 304.

[0078] The second elastic element 402, fitted onto the extension post 303, abuts against the portion of the base plate 103 near the guide hole 108 and the stop plate 301.

[0079] The third elastic element 403, fitted onto the extension post 304, abuts against the portion of the base plate 103 near the guide hole 109 and the stop plate 301.

[0080] The extension post 303 of the slider 300 is inserted into the guide hole 108, and the extension post 304 of the slider 300 is inserted into the guide hole 109. As the slider 300 moves toward or away from the circuit board assembly 500, the extension post 303 can slide along the guide hole 108, and the extension post 304 can slide along the guide hole 109.

[0081] In an exemplary implementation, such as Figure 4 As shown, the stop plate 301 is provided with a through hole 305 for the guide post 102 to pass through, so that the slider 300 can be fitted on the guide post 102 and slide along the guide post 102.

[0082] The relative sliding of the extension post 303 and the guide hole 108, the relative sliding of the extension post 304 and the guide hole 109, and the relative sliding of the through hole 305 and the guide post 102 together make the sliding of the slider 300 more stable.

[0083] In an exemplary implementation, such as Figure 1 and Figure 2 As shown, the power socket capable of detecting the power plug further includes: an upper housing 701 and a lower housing 702, which can form an accommodating space for surrounding and supporting the circuit board assembly 500, the terminal support 100, and the conductive terminals 201 and 202.

[0084] In an exemplary implementation, such as Figure 1 and Figure 2 As shown, the upper housing 701 is provided with sockets 703 and 705 for inserting a power plug. The power socket capable of detecting the power plug further includes a cover plate 704, which is disposed on the upper housing 701 and is used to cover the sockets 703 and 705 of the upper housing 701.

[0085] The socket 703 corresponds to the conductive terminal 202, and the socket 705 corresponds to the conductive terminal 201.

[0086] In an exemplary embodiment, the photoelectric sensor 600 is disposed on the side of the circuit board assembly 500 away from the terminal support 100.

[0087] The specific position of the photoelectric sensor 600 on the circuit board assembly 500 can be adjusted according to the actual situation, as long as the above functions can be achieved.

[0088] This utility model also provides a vehicle equipped with the aforementioned power socket capable of detecting the power plug.

[0089] The operation of the power socket capable of detecting power plugs according to the present invention will be described below with reference to the accompanying drawings.

[0090] The conductive terminal 201 allows a two-pronged power plug 801 to be inserted, and the conductive terminal 202 allows a three-pronged power plug 802 to be inserted.

[0091] The two-prong power plug 801 is inserted into the socket 705 of the upper housing 701 and passes through the conductive terminal 201. After passing through the conductive terminal 201, the two-prong power plug 801 contacts the first contact portion 308 of the slider 300 and pushes the slider 300 towards the circuit board assembly 500 (see also [reference]). Figure 4 and Figure 7 ).

[0092] Alternatively, the three-pronged power plug 802 is inserted into the socket 703 of the upper housing 701 and passes through the conductive terminal 202. After passing through the conductive terminal 202, the three-pronged power plug 802 contacts the second contact portion 309 of the slider 300 and pushes the slider 300 toward the circuit board assembly 500 (see also [reference]). Figure 4 and Figure 8 ).

[0093] Under the push of the two-prong power plug 801 or the three-prong power plug 802, the slider 300 overcomes the elastic force of the first elastic member 401, the second elastic member 402, and the third elastic member 403 and moves along the guide post 102 toward the circuit board assembly 500 (i.e., in Figure 7 and Figure 8 The slider moves downward so that the extension plate 302 of the slider 300 passes through the second through groove 501 and the first through groove 101, thereby causing the photoelectric sensor 600 to generate a trigger signal. The trigger signal can trigger the controller 900 to control the conductive terminal 201 and the conductive terminal 202 to be energized.

[0094] Figures 1 to 3 In the implementation scheme, the positional relationship between conductive terminals 201 and 202 ensures that only one power plug can be inserted, i.e., only a two-prong power plug 801 or a three-prong power plug 802 can be inserted. Whether the two-prong power plug 801 or the three-prong power plug 802 is inserted, conductive terminals 201 and 202 will be energized.

[0095] Alternatively, the positional relationship between conductive terminals 201 and 202 can be designed so that two power plugs can be inserted simultaneously, that is, two-pronged power plug 801 and three-pronged power plug 802 can be inserted simultaneously (this case is not shown in the figure).
