Description

Technical Field

[0056] In some embodiments, a charging terminal is provided for charging an electric vehicle or other device. The charging terminal charges the electric vehicle or other device through a charging gun.

[0057] Figure 1 The figure shows an exploded view of the charging terminal. The charging device comprises a shell, and a mounting cavity is formed inside the shell.

[0058] Specifically, the housing includes a base 230, a front housing 210, a rear housing 220 and an upper cover 240. The front housing 210 and the rear housing 220 are respectively fixedly connected to the base 230, and the front housing 210 and the rear housing 220 are connected to form a circumferential wall of the housing. The upper cover 240 is fixedly arranged on the top of the front housing 210 and the rear housing 220.

[0059] The stand 250 is fixedly arranged in the internal mounting cavity of the housing, and the control component 500 is fixedly arranged on the stand 250. The control component 500 is configured to control the charging of the charging terminal. The control component 500 includes a mainboard module 510 and a copper busbar module 520. The mainboard module 510 is arranged above the copper busbar module 520.

[0060] A gun seat 280 for placing a charging gun is provided on the front shell 210. A heat dissipation through hole 215 is provided at the bottom of the front shell 210. The heat inside the shell can be discharged from the charging terminal through the heat dissipation through hole 215 at the bottom.

[0061] In some embodiments, the charging terminal includes a display screen assembly 100. The display screen assembly 100 is fixedly disposed on the front housing 210. The display screen assembly 100 is located above the gun mount 280.

[0062] Figure 2 FIG. 1 is a partial structural diagram of the front housing 210 and the display screen assembly 100. Figure 3 FIG. 1 is a partial cross-sectional view of the front housing 210 and the display screen assembly 100. Figure 4 FIG. 1 is a structural diagram of the display screen assembly 100 viewed from the outside. Figure 5 FIG. 1 is a structural diagram of the display screen assembly 100 viewed from the inside. Figure 8 A partial structural diagram of the front shell 210 is shown.

[0063] The front shell 210 is provided with a mounting groove, and the display screen assembly 100 is fixedly disposed in the mounting groove. The display screen assembly 100 is located outside the front shell 210 .

[0064] The display screen assembly 100 includes a display screen module 110 and a mounting portion 120 . Figure 7 FIG. 1 is a structural diagram of a display screen module 110 .

[0065] The mounting portion 120 is configured to mount the display screen module 110, that is, the display screen module 110 is fixedly mounted on the mounting portion 120. The mounting portion 120 is fixedly mounted on a side of the front housing 210 away from the mounting cavity. The mounting portion 120 serves as a mounting carrier of the display screen module 110 to achieve fixed mounting of the display screen module 110 on the front housing 210.

[0066] Reference Figure 3, a first heat dissipation hole 212 is arranged at the upper position of the front shell 210, that is, the first heat dissipation hole 212 is arranged near the top of the installation cavity, and a second heat dissipation hole 123 is correspondingly arranged on the installation portion 120, and a heat dissipation channel is formed between the front shell 210 and the installation portion 120, and the heat dissipation channel is connected with the installation cavity through the first heat dissipation hole 212, and the heat dissipation channel and the second heat dissipation hole 123 are sequentially discharged from the charging terminal. The charging terminal has two heat dissipation air paths, the first path is for the heat in the inner cavity of the shell to be discharged through the heat dissipation through hole 215 at the bottom of the front shell 210, and the second path is for the heat in the inner cavity of the shell to be discharged through the first heat dissipation hole 212, the heat dissipation channel and the second heat dissipation hole 123 at the top of the front shell 210. By adding a heat dissipation air path at the top, the heat dissipation effect of the charging terminal is improved, which helps to improve the charging reliability of the charging terminal.

[0067] When the charging terminal is working, the control component 500 generates a large amount of heat, which increases the air temperature. The hot air rises and gathers in the top space of the shell cavity. If the heat is only dissipated through the heat dissipation holes 215 at the bottom as in the prior art, the large amount of hot air gathered at the top needs to move downward and flow through the mainboard module 510 and the copper busbar module 520 again before reaching the heat dissipation holes 215 at the bottom and then being discharged. It can be seen that the heat dissipation path is long and the heat dissipation effect is poor.

[0068] The present invention sets the first heat dissipation hole 212 at a position higher than the control component 500, so that the top heat dissipation air path composed of the first heat dissipation hole 212, the heat dissipation channel and the second heat dissipation hole 123 is higher than the control component 500, and utilizes the physical property of hot air rising to make the hot air gathered on the top of the inner cavity of the shell directly discharged from the charging terminal through the top heat dissipation air path, shortening the heat dissipation path and improving the heat dissipation efficiency and effect.

[0069] In other words, the first heat dissipation hole 212 and the second heat dissipation hole 123 arranged on the top of the shell of the present invention are equivalent to the exhaust chimney of the hot air in the inner cavity of the shell, which improves the exhaust efficiency and thus improves the heat dissipation effect.

[0070] In some embodiments, the mounting portion 120 includes a bracket 121 and a transparent member 122 . Figure 6 The figure shows a structure diagram of the bracket 121. The transparent member 122 is, for example, tempered glass.

[0071] The bracket 121 is a rectangular structure as a whole, and the display screen module 110 is fixedly mounted on the bracket 121 by means of screws or the like, specifically, fixedly mounted on the inner side of the bracket 121, that is, the side of the bracket 121 facing the front housing 210. An opening 1211 is provided on the bracket 121, and the display screen module 110 is exposed from the opening 1211, so as to display the electronic interface to the user.

[0072] The transparent member 122 is fixedly mounted on the outer side of the bracket 121, that is, the side of the bracket 121 away from the front housing 210, by means of sealant or the like. The transparent member 122 covers the opening 1211 to cover the display screen module 110 and protect the display screen module 110.

[0073] The bracket 121 is fixedly mounted on the front housing 210 by means of screws, buckles, etc. Figure 5 and Figure 8 A clamping claw 1213 is provided on the bracket 121 , and a bayonet 216 is provided on the front shell 210 . The clamping claw 1213 is clamped in the bayonet 216 to achieve fixed installation of the bracket 121 on the front shell 210 , thereby achieving fixed installation of the display screen module 110 on the front shell 210 .

[0074] Reference Figure 3 A heat dissipation channel is formed between the bracket 121 and the front shell 210. A second heat dissipation inner hole 1232 is provided on the bracket 121, and a second heat dissipation outer hole 1231 is provided on the transparent member 122. The second heat dissipation inner hole 1232 is directly connected with the second heat dissipation outer hole 1231 to form a second heat dissipation hole 123. The heat in the inner cavity of the shell is discharged from the charging terminal through the first heat dissipation hole 212, the heat dissipation channel, the second heat dissipation inner hole 1232, and the second heat dissipation outer hole 1231 in sequence.

[0075] from Figure 3 It can be seen that the second heat dissipation air path is formed above the display screen module 110, does not pass through the display screen module 110, and does not interfere with the installation of the display screen module 110. The mounting portion 120 composed of the bracket 121 and the transparent member 122 not only realizes the fixed installation of the display screen module 110 on the front shell 210, but also increases the heat dissipation air path of the charging terminal.

[0076] In some embodiments, reference Figure 7 The display screen module 110 includes a display screen body 111 and a circuit board 112 . The display screen body 111 is fixedly connected to the circuit board 112 . The circuit board 112 is fixedly mounted on the bracket 121 by means of screws or the like. The display screen body 111 is exposed from the opening 1211 .

[0077] In a specific embodiment, referring to Figure 6 and Figure 7 Screw holes 1121 are respectively arranged at the four corners of the circuit board 112 , and screw columns 1212 are correspondingly arranged on the bracket 121 . Screws pass through the screw holes 1121 and the screw columns 1212 to fix the display screen module 110 to the bracket 121 .

[0078] In some embodiments, reference Figure 6 and Figure 7A positioning column 1122 is provided on the circuit board 112 , and a positioning hole 1214 is correspondingly provided on the bracket 121 . The positioning column 1122 is inserted into the positioning hole 1214 , so as to realize the pre-positioning of the display screen module 110 on the bracket 121 .

[0079] In some embodiments, reference Figure 3 and Figure 7 A sealant is disposed between the display screen body 111 and the transparent member 122 , which is denoted as a first sealant 310 . The first sealant 310 is disposed close to the circumferential edge of the display screen body 111 and extends along the circumference of the display screen body 111 .

[0080] The provision of the first sealant 310 , on the one hand, improves the installation reliability of the display screen body 111 and the transparent member 122 ; on the other hand, realizes the circumferential sealing of the display screen body 111 , prevents external dust, rainwater, etc. from entering the gap between the display screen body 111 and the transparent member 122 , and ensures the display performance and reliability of the display screen body 111 .

[0081] In some embodiments, the top heat dissipation air path is set so that external rainwater may enter the interior of the housing through the first heat dissipation hole 212 and the second heat dissipation hole 123. Therefore, it is also necessary to design the top heat dissipation air path waterproof to ensure the heat dissipation effect of the second heat dissipation air path while preventing external rainwater from entering.

[0082] In some embodiments, reference Figure 3 The second heat dissipation hole 123 is set at a position lower than the first heat dissipation hole 212, which is conducive to preventing rainwater or ice and snow from the outside from entering the second heat dissipation hole 123 through the first heat dissipation hole 212. If the second heat dissipation hole 123 is set at a position higher than the first heat dissipation hole 212, then after the external water flows into the heat dissipation channel between the first heat dissipation hole 212 and the second heat dissipation hole 123 through the second heat dissipation hole 123, it is easy to flow into the inner cavity of the housing through the first heat dissipation hole 212 and cause adverse effects on the control component 500.

[0083] In the present disclosure, the first heat dissipation hole 212 and the second heat dissipation hole 123 are staggered in the vertical direction. After external water flows into the heat dissipation channel between the first heat dissipation hole 212 and the second heat dissipation hole 123 through the second heat dissipation hole 123, it is not easy to flow into the inner cavity of the shell through the first heat dissipation hole 212, which helps to improve the waterproofness of the inner cavity of the shell.

[0084] In some embodiments, the charging terminal includes a waterproof portion, which is configured to prevent water flowing in from the second heat dissipation hole 123 from flowing into the first heat dissipation hole 212 through the heat dissipation channel, thereby improving the waterproof performance and charging reliability of the charging terminal.

[0085] In some embodiments, reference Figure 3The waterproof part includes a water retaining rib (i.e., a second water retaining rib 214), which is arranged in the heat dissipation channel. The water retaining rib is configured to prevent water that flows into the heat dissipation channel through the second heat dissipation hole 123 from flowing into the first heat dissipation hole 212 again, thereby further improving the waterproofness of the inner cavity of the shell.

[0086] In some implementations, reference Figure 3 The display screen assembly 100 further includes a waterproof net 130 . The waterproof net 130 is disposed between the bracket 121 and the transparent member 122 , and covers the air flow passage between the second heat dissipation inner hole 1232 and the second heat dissipation outer hole 1231 .

[0087] The waterproof net 130 blocks external rainwater, dust, etc., and prevents external rainwater, dust, etc. from entering the interior of the housing through the second heat dissipation inner hole 1232 and the second heat dissipation outer hole 1231 .

[0088] In some embodiments, continue to refer to Figure 3 The bracket 121 and the transparent member 122 are fixed by a sealant, which is referred to as a second sealant 320 , to improve the installation stability of the transparent member 122 on the bracket 121 .

[0089] The waterproof net 130 is squeezed and limited between the bracket 121 and the tempered glass, thereby improving the installation stability of the waterproof net 130 .

[0090] In some embodiments, the waterproof net 130 acts as a first layer of blocking for external rainwater. When the external rainwater is heavy, external rainwater may still flow into the front shell 210 through the second heat dissipation outer hole 1231 and the second heat dissipation inner hole 1232. Therefore, a drainage structure needs to be provided on the front shell 210 to promptly discharge the rainwater on the front shell 210 to the outside of the shell to prevent the rainwater from flowing into the installation cavity inside the shell through the first heat dissipation hole 212 on the front shell 210.

[0091] Specifically, refer to Figure 3 and Figure 8 The waterproof part includes a drainage groove 211, which is arranged on the side of the front shell 210 facing the display screen assembly 100. The drainage groove 211 passes around the display screen module 110. The second heat dissipation hole 123 is connected to the drainage groove 211, and the water entering from the second heat dissipation hole 123 flows into the drainage groove 211 and is discharged from the charging terminal through the drainage groove 211.

[0092] The rainwater flowing in through the second heat dissipation holes 123 flows out through the drainage grooves 211 on the front shell 210 in time, so as to prevent the rainwater from entering the inner cavity of the shell through the first heat dissipation holes 212 on the front shell 210 .

[0093] Combination Figure 3The first heat dissipation hole 212 is set at a higher position than the second heat dissipation hole 123, and the drainage groove 211 is set at a lower position than the first heat dissipation hole 212. If external rainwater flows in through the second heat dissipation hole 123, the rainwater first flows into the drainage groove 211. Since the drainage groove 211 is lower than the first heat dissipation hole 212, the water in the drainage groove 211 cannot flow into the inner cavity of the shell through the first heat dissipation hole 212, but is discharged from the charging terminal along the drainage groove 211, thereby improving the waterproof effect of the whole machine on the basis of ensuring the top heat dissipation air path.

[0094] In addition, the drainage groove 211 bypasses the display screen module 110 , and rainwater is discharged bypassing the display screen module 110 , thereby preventing rainwater from penetrating into the display screen module 110 .

[0095] In some embodiments, reference Figure 3 and Figure 8 The drainage groove 211 includes a first drainage groove section 2111 and a second drainage groove section 2112. The first drainage groove section 2111 is located above the display screen module 110, and the second drainage groove section 2112 is located on the side of the display screen module 110. The second heat dissipation hole 123 is directly opposite to the first drainage groove section 2111. The second heat dissipation hole 123, the first drainage groove section 2111, and the second drainage groove section 2112 are connected in sequence. The water entering through the above heat dissipation holes can be discharged from the charging terminal through the first drainage groove section 2111 and the second drainage groove section 2112 in sequence.

[0096] After the external rainwater flows in through the second heat dissipation hole 123, it first enters the first drainage groove 2111. The water in the first drainage groove 2111 then flows out to the bottom of the front shell 210 through the second drainage groove 2112, and then is discharged from the charging terminal.

[0097] There are two second drainage groove sections 2112, and the second drainage groove sections 2112 are respectively provided on the left and right sides of the display screen module 110. The two second drainage groove sections 2112 are helpful to improve the drainage efficiency.

[0098] In some embodiments, reference Figure 3 and Figure 8 The front shell 210 is provided with a first water retaining rib 213 and a second water retaining rib 214, which are integrally formed with the front shell 210. The first water retaining rib 213 and the second water retaining rib 214 form a drainage groove section 2111, and the first water retaining rib 213 is located below the second water retaining rib 214.

[0099] An air flow gap 400 is formed between the second water retaining rib 214 and the mounting portion 120 , specifically, between the second water retaining rib 214 and the bracket 121 , and the heat in the mounting cavity inside the shell is discharged from the charging terminal through the first heat dissipation hole 212 , the air flow gap 400 and the second heat dissipation hole 123 in sequence.

[0100] The second water retaining rib 214 serves as a second barrier for external rainwater, thereby preventing water in the first drainage groove section 2111 from flowing over the second water retaining rib 214 and into the inner cavity of the housing through the first heat dissipation hole 212 .

[0101] A sealant is provided between the first water retaining rib 213 and the mounting portion 120, which is recorded as the third sealant 330, to improve the sealing between the two, so as to prevent the water in the first drainage groove section 2111 from flowing downward into the display screen module 110. In addition, the third sealant 330 also plays a role in guiding water, and the water in the first drainage groove section 2111 flows along the first water retaining rib 213 and the third sealant 330 to the second drainage groove section 2112 on both sides until it flows into the second drainage groove section 2112.

[0102] In some embodiments, a charging system is provided, which includes the charging terminal disclosed in the above embodiments.

[0103] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0104] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
