[0072] This application discloses an auxiliary pulling device, a telescopic data cable assembly and a vehicle charger, which include some or all of the technical features of the following embodiments; that is, the auxiliary pulling device, the telescopic data cable assembly and the vehicle charger include some or all of the following structures. In one embodiment of this application, an auxiliary pulling device for a telescopic data cable includes a fixed seat, a horizontal shaft, a pair of springs and a pair of pins; the fixed seat is provided with a pair of first through holes and a pair of chutes, and the horizontal shaft is provided with a pair of second through holes corresponding to the pair of first through holes; the horizontal shaft passes through the pair of chutes respectively, and the pair of chutes are integrally located between the pair of second through holes; each pin sequentially passes through a first through hole, a spring and a second through hole, and abuts against the fixed seat; the horizontal shaft is used for elastically sliding towards the fixed seat along the pair of pins in a state of being pressured by the telescopic data cable. The above-mentioned auxiliary pulling device for the telescopic data cable provides an elastic contact position through the cooperation of the horizontal shaft, the fixed seat, the spring and the pin; under the elastic action of the spring, for the pulling force of the wire assembly of the telescopic data cable, the position of the horizontal shaft can be adaptively adjusted, so as to realize pulling out the data cable in a larger angle range, thereby improving the applicability of the telescopic data cable; and by adjusting the elastic force of the spring, the force-bearing position and the degree of force-bearing displacement of the horizontal shaft can be adjusted, while pulling out the data cable in a larger angle range, ensuring the smooth contraction of the data cable, so it is more convenient and reliable to use. The following combines Figures 1 to 18 , and the auxiliary pulling device, the telescopic data cable assembly and the vehicle charger will be described in detail.

[0073] In one of the embodiments, an auxiliary pulling device 160 for a telescopic data cable is as Figure 1 shown, which includes a fixed seat 161, a horizontal shaft 164, a pair of springs 162 and a pair of pins 163; combined with Figure 2 and Figure 3 , the fixed seat 161 is provided with a pair of first through holes 191 and a pair of chutes 189, and the pair of chutes 189 are integrally located between the pair of first through holes 191; that is, the distance between the pair of first through holes 191 is greater than the distance between the pair of chutes 189, so that one of the first through holes 191 is located on one side of the pair of chutes 189, and the other first through hole 191 is located on the other side of the pair of chutes 189. The fixed seat 161 is the basic structural member of the auxiliary pulling device 160, and the horizontal shaft 164, the pair of springs 162 and the pair of pins 163 are all directly or indirectly arranged on the fixed seat 161.

[0074] The transverse shaft 164 is provided with a pair of second through holes 192 corresponding to the pair of first through holes 191; that is, each second through hole 192 corresponds to one first through hole 191, and each first through hole 191 corresponds to one second through hole 192, and the first through holes 191 and the second through holes 192 are arranged in one-to-one correspondence. Moreover, the transverse shaft 164 passes through the pair of sliding grooves 189 respectively, and the pair of sliding grooves 189 are entirely located between the pair of second through holes 192; that is to say, the distance between the pair of second through holes 192 is greater than the distance between the pair of sliding grooves 189, so that in the state where the transverse shaft 164 passes through the pair of sliding grooves 189, one second through hole 192 is located on one side of the pair of sliding grooves 189, and the other second through hole 192 is located on the other side of the pair of sliding grooves 189. Such a structural design enables the transverse shaft 164 to perform a limiting movement in the pair of sliding grooves 189.

[0075] As Figure 1 shown, each latch 163 sequentially passes through a first through hole 191, a spring 162, and a second through hole 192, and abuts against the fixed seat 161; combined with Figure 2 and Figure 3 , in one embodiment of the present embodiment, the fixed seat 161 is further provided with blind holes 188, and the latch 163 abuts against the blind holes 188; that is to say, the fixed seat 161 is provided with two blind holes 188, and each latch 163 abuts against one blind hole 188. As an example, the latch 163 has two ends, one end of one latch 163 abuts against one blind hole 188, and the other end is located on one first through hole 191 or on the fixed seat 161; similarly, one end of the other latch 163 abuts against the other blind hole 188, and the other end is located on the other first through hole 191 or on the fixed seat 161. Such a structural design enables the transverse shaft 164 to move limitedly in the pair of sliding grooves 189 along the length direction of the pair of latches 163.

[0076] Both ends of the transverse shaft 164 abut against two springs 162 respectively, so the transverse shaft 164 can elastically move along the pair of latches 163, and the movement of the transverse shaft 164 is also restricted by the position of the sliding groove 189. In each embodiment, combined with Figure 6 and Figure 9, the horizontal shaft 164 is used to elastically slide in a pair of the sliding grooves 189 along a pair of the pins 163 toward the first through hole 191 of the fixed seat 161 in a state of being pressed by the telescopic data cable 110. If the pressure of the telescopic data cable 110 is greater than the elastic force of the spring 162, the horizontal shaft 164 moves toward the first through hole 191 of the fixed seat 161; if the pressure of the telescopic data cable 110 disappears, under the action of the elastic force of the spring 162, the horizontal shaft 164 moves away from the first through hole 191 of the fixed seat 161; and these movements are all carried out in the sliding grooves 189. Therefore, the movement of the horizontal shaft 164 is controllable. The horizontal shaft 164 cooperates with the fixed seat 161, the spring 162 and the pin 163 to provide an elastic contact position for the telescopic data cable 110 through the horizontal shaft 164; under the elastic action of the spring 162, when the horizontal shaft 164 is pulled by the wire 112 of the telescopic data cable 110, the position of the horizontal shaft 164 itself can be adaptively adjusted, so as to realize pulling out the data cable in a larger angle range, and further improve the applicability of the telescopic data cable 110; and by adjusting the elastic force of the spring 162, the force-bearing position and the degree of force-bearing displacement of the horizontal shaft 164 can be adjusted, while pulling out the data cable in a larger angle range, ensuring the smooth contraction of the data cable, so it is more convenient and reliable to use.

[0077] In one embodiment, as Figure 3 shown, the fixed seat 161 includes a fixing plate 181, a connecting plate 182, a top plate 183 and a pair of support plates 184; one end of the connecting plate 182 is connected to the fixing plate 181, and the other end is connected to the top plate 183. Both sides of the top plate 183 are respectively connected with one of the support plates 184 and are respectively provided with first protrusions 186; each of the support plates 184 is provided with one of the sliding grooves 189, and each of the support plates 184 is provided with a second protrusion 187 on a side away from the top plate 183; each of the first protrusions 186 is provided with the first through hole 191, each of the second protrusions 187 is provided with a blind hole 188, and the pin 163 abuts against the blind hole 188. In this embodiment, the fixing plate 181 is provided with fixing holes 185, combined with Figure 9 , the fixing plate 181 is fixed to the telescopic data cable telescopic mechanism 115 of the telescopic data cable 110 through the fixing holes 185; as an example, the fixing plate 181 is screwed to the telescopic data cable telescopic mechanism 115 of the telescopic data cable 110 through the fixing holes 185. In this embodiment, the two first protrusions 186 and the two second protrusions 187 are arranged in one-to-one correspondence, and a space is left between each of the first protrusions 186 and its corresponding second protrusion 187, that is, no structural member is provided, so as to form a space that can accommodate other structural members. Figure 3The illustrated embodiment gives a specific structural example of the fixing base 161. In specific applications, the fixing base 161 can also be implemented using other structures. Figure 3 The illustrated structure should not be regarded as an additional limitation to the fixing base 161.

[0078] In order to further improve the adaptability to the angle range, in one of the embodiments, as Figure 1 and Figure 2 shown, the auxiliary pulling device 160 further includes a roller 166. The roller 166 is provided with a third through hole 193, and the horizontal shaft 164 passes through the third through hole 193. A pair of the second through holes 192 are respectively located on both sides of the roller 166. Exemplarily, the roller 166 has a shape that is thin in the middle and thick at both ends, and gradually thickens from the middle to both ends. In a state where the telescopic data cable 110 or its wire 112 applies pressure to the roller 166, the roller 166 can rotate along the horizontal shaft 164 and drive the horizontal shaft 164 to move together within the range defined by the chute 189 and the plug 163, thereby further increasing the angle range for pulling out the data cable, that is, the data cable can be pulled horizontally or obliquely. Details will be described in the following accompanying drawings. It can be understood that the shape of the roller is not limited to the above shape, that is, the illustrated shape, and can also be set to other shapes.

[0079] In order to facilitate the positioning of the plug 163, in one of the embodiments, as Figure 1 and Figure 2 shown, the auxiliary pulling device 160 further includes a pair of snap rings 165. Each plug 163 is provided with a snap ring groove 194 at one end close to the first through hole 191, and each snap ring 165 is clamped on one of the snap ring grooves 194 to limit the plug 163 on the fixing base 161. In other embodiments, for the embodiments having the first protrusion 186, the plug 163 can also be screwed into the first through hole 191 of the first protrusion 186, or the plug 163 is in interference fit with the first through hole 191 of the first protrusion 186. Such a structural design is beneficial to limit the position of the plug 163 and quickly assemble the plug 163 on the fixing base 161.

[0080] In one of the embodiments, a telescopic data cable assembly 100 is as Figure 4 and Figure 5 shown. It includes a housing assembly 150, a telescopic data cable 110, and the auxiliary pulling device 160 according to any of the embodiments. The auxiliary pulling device 160 is disposed in the housing assembly 150. The housing assembly 150 is provided with an outlet 152. In combination with Figure 6, the telescopic data cable 110 includes a telescopic mechanism 115 of the telescopic data cable, a wire 112, and a connection end 111 that are sequentially connected. The telescopic mechanism 115 of the telescopic data cable is disposed in the housing assembly 150. The connection end 111 is located outside the housing assembly 150. The wire 112 passes through the wire outlet 152 and abuts against the horizontal axis 164 of the auxiliary pulling device 160. The wire 112 is telescopically wound around the telescopic mechanism 115 of the telescopic data cable. For an embodiment having a roller 166, the wire 112 abuts against the roller 166 of the auxiliary pulling device 160. With such a design, through the cooperation of the wire 112 and the auxiliary pulling device 160, when the wire 112 is stretched or retracted, pressure is applied to the horizontal axis 164, so that the position of the horizontal axis 164 can be elastically adjusted, and further a larger angle of pulling out the wire 112 is achieved and the smooth contraction of the wire 112 is ensured. Therefore, while ensuring the normal use of the product, the applicability of the product is also improved.

[0081] In the illustrated embodiment, the connection end 111 is a TYPE C male end. In other embodiments, the connection end 111 may be one of a TYPE C male end, a Micro USB male end, and a Lightning male end. In the illustrated embodiment, the telescopic data cable 110 is provided with one connection end 111. In other embodiments, the number of connection ends 111 may be two.

[0082] In one embodiment, as Figure 4 and Figure 6 shown, the housing assembly 150 includes a main housing 153, a first housing 154, and a top cover 155. The main housing 153 and the first housing 154 together enclose a first accommodation area 151, and at least one of the main housing 153 and the first housing 154 is provided with the wire outlet 152 communicating with the first accommodation area 151. As an example, the main housing 153 is provided with the wire outlet 152 communicating with the first accommodation area 151, or the first housing 154 is provided with the wire outlet 152, or both the main housing 153 and the first housing 154 are provided with the wire outlet 152. And, the telescopic mechanism 115 of the telescopic data cable and the auxiliary pulling device 160 are disposed in the first accommodation area 151, and the auxiliary pulling device 160 is fixed on the telescopic mechanism 115 of the telescopic data cable. The top cover 155 is connected to the main housing 153 to close the first accommodation area 151. In one embodiment, the top cover 155, the main housing 153, and the first housing 154 are separately provided. In other embodiments, the top cover 155 and the main housing 153 are integrally provided, or the main housing 153 and the first housing 154 are integrally provided. Such a structural design is beneficial to assembling the telescopic data cable assembly 100.

[0083] By designing the shape of the first housing 154, the telescopic data cable assembly 100 can be directly designed as a vehicle charger. In one embodiment, a vehicle charger 900 is as Figure 7 and Figure 8 shown, which includes a control component 250, a conductive connection member 270, and the telescopic data cable assembly 100 according to any one of the embodiments; combining Figure 9 and Figure 10 , the control component 250 and the conductive connection member 270 are disposed in the housing assembly 150 of the telescopic data cable assembly 100, and the conductive connection member 270 is provided with an end portion 271 located outside the housing assembly 150, and the conductive connection member 270 is used to conductively connect to the power supply terminal of the vehicle through the end portion 271; the wire 112 of the telescopic data cable assembly 100 is conductively connected to the conductive connection member 270 through the control component 250. Such a design can pull out the wire 112 of the telescopic data cable assembly 100 at a larger angle and ensure the smooth contraction of the wire 112. Therefore, there is a telescopic data cable assembly 100 that can be pulled out at a larger angle, which is particularly suitable for use in an application environment where the position of the vehicle charger 900 is limited, and while ensuring the normal use of the product, the applicability of the product is also improved.

[0084] As an example, as Figure 4 or Figure 11 shown, the wire 112 of the telescopic data cable assembly 100 can be pulled out horizontally, that is, the wire 112 is pulled out in the horizontal direction; or as Figure 5 or Figure 12 shown, the wire 112 of the telescopic data cable assembly 100 is pulled out obliquely, that is, the wire 112 is pulled out obliquely relative to the horizontal direction. In this state, the wire 112 applies pressure to the cross shaft 164 or the roller 166 of the auxiliary pulling device 160, so that the cross shaft 164 compresses a pair of springs 162 and elastically slides along a pair of the pins 163 toward the first through hole 191 of the fixed seat 161, and the position of this elastic sliding is also restricted by a pair of the sliding grooves 189. When it is necessary to retract the wire 112, when the pressure applied by the wire 112 to the cross shaft 164 or the roller 166 of the auxiliary pulling device 160 is small, the elastic restoring force of a pair of springs 162 drives the cross shaft 164 to elastically slide along a pair of the pins 163 away from the first through hole 191 of the fixed seat 161.

[0085] In this embodiment, the telescopic data cable assembly 100 further includes a conductive structural member 170, and the wire 112 is electrically connected to the control assembly 250 through the conductive structural member 170. In order to protect the wire outlet 152 and the wire 112, in one embodiment, the telescopic data cable 110 is provided with a port protection member 113 at the wire outlet 152 to protect the wire outlet 152 and the wire 112. As an example, the port protection member 113 is a rubber part, which is covered outside the wire outlet 152 or embedded outside the wire outlet 152. Such a structural design is beneficial to protecting the wire outlet 152 and the wire 112.

[0086] In one embodiment, as Figure 9 shown, the telescopic data cable 110 is provided with a threaded hole 116 in the telescopic mechanism 115 of the telescopic data cable, and the auxiliary pulling device 160 is provided with a fixing hole 185 in the fixing plate 181. The auxiliary pulling device 160 can use screws or bolts, etc., and is screwed to the threaded hole 116 through the fixing hole 185, so that the fixing plate 181 is fixed to the telescopic mechanism 115 of the telescopic data cable.

[0087] In one embodiment, as Figure 13 and Figure 15 shown, the connection end 111 is provided with a third magnetic attracting member 114. Combining Figure 16 , the housing assembly 150 is provided with a fourth magnetic attracting member 190. The third magnetic attracting member 114 and the fourth magnetic attracting member 190 are magnetically attracted to fix the connection end 111 on the housing assembly 150, thereby restricting the position of the connection end 111. In one embodiment, for the embodiment with the first accommodation area 151, the fourth magnetic attracting member 190 is disposed in the first accommodation area 151, and the fourth magnetic attracting member 190 is disposed on the inner wall of the housing assembly 150. As an example, the fourth magnetic attracting member 190 is disposed on the main housing 153 or the inner wall of the first housing 154 of the housing assembly 150. Such a structural design makes the vehicle charger 100 very suitable for use in vehicles. When the telescopic data cable assembly 110 is not in use, the wire 112 can be retracted to a certain extent, and the connection end 111 can be magnetically attracted to the housing assembly 150, such as the first housing 154, by the fourth magnetic attracting member 190 through the third magnetic attracting member 114, so as to maintain the relative position between the connection end 111 and the housing assembly 150. When the telescopic data cable assembly 110 is in use, an external force overcomes the magnetic attraction force of the fourth magnetic attracting member 190 on the third magnetic attracting member 114, and the wire 112 can be conveniently pulled out from the housing assembly 150 or its first accommodation area 151, so it does not affect the use.

[0088] In addition to being integrated with the control component 250 and the conductive connection member 270 in a housing, the telescopic data cable assembly 100 can also be separately provided from the control component 250 and the conductive connection member 270. In one embodiment, a vehicle charger 900 is as Figure 13 and Figure 14 shown, which includes a charger main body 200 and a telescopic data cable assembly 100, and the telescopic data cable assembly 100 can be the telescopic data cable assembly 100 described in any embodiment.

[0089] In one embodiment, as Figure 15 and Figure 16 shown, the telescopic data cable assembly 100 further includes a first magnetic attraction member 120, a first spring pin connection end 130, and a conductive structure member 170; the wire 112 is electrically connected to the first spring pin connection end 130 through the conductive structure member 170. The first magnetic attraction member 120 is used to cooperate with the second magnetic attraction member 220 of the charger main body 200 to detachably connect the telescopic data cable assembly 100 and the charger main body 200 in a magnetic adsorption manner; since the positions of the first magnetic attraction member 120 and the second magnetic attraction member 220 correspond to each other, and the positions of the first spring pin connection end 130 and the second spring pin connection end 230 correspond to each other, when the telescopic data cable assembly 100 is connected or fixed to the charger main body 200, the first spring pin connection end 130 is used to electrically connect to the second spring pin connection end 230 of the charger main body 200.

[0090] In this embodiment, the telescopic data cable assembly 100 further includes a first connection portion 140. The first connection portion 140 is used for concave-convex fitting or snap fitting with the second connection portion 240 of the charger main body 200, so that the telescopic data cable assembly 100 and the charger main body 200 are fixed more accurately and stably. Similarly, when the first connection portion 140 is used for concave-convex fitting or snap fitting with the second connection portion 240 of the charger main body 200, since the positions of the first magnetic attraction member 120 and the second magnetic attraction member 220 correspond to each other, the positions of the first connection portion 140 and the second connection portion 240 correspond to each other, and the positions of the first spring pin connection end 130 and the second spring pin connection end 230 correspond to each other, the first spring pin connection end 130 can accurately electrically connect to the second spring pin connection end 230 of the charger main body 200.

[0091] In one embodiment, as Figure 17 and Figure 18 shown, the charger main body 200 is provided with an adapter housing 210, a second magnetic attraction member 220, a second spring pin connection end 230, a second housing 260, and a conductive connection member 270; combined with Figure 9, the charger main body 200 is further provided with a control component 250. The adapter housing 210 is used to abut against the power supply end of the vehicle. The adapter housing 210 is provided with a second accommodation area 211. The second housing 260 is connected to the adapter housing 210 to enclose the second accommodation area 211. The second magnetic member 220 is disposed in the second accommodation area 211 and is close to or abuts against the second housing 260. The second magnetic member 220 is used to cooperate with the first magnetic member 120 of the telescopic data line assembly 100 to detachably connect the telescopic data line assembly 100 to the charger main body 200 in a magnetic adsorption manner. And in the connected state, due to the corresponding positions of the first magnetic member 120 and the second magnetic member 220, and the corresponding positions of the first spring pin connection end 130 and the second spring pin connection end 230, the second spring pin connection end 230 contacts the first spring pin connection end 130 to achieve electrical connection. The control component 250 is disposed in the second accommodation area 211 and is electrically connected to the second spring pin connection end 230. The conductive connection member 270 is disposed in the second accommodation area 211 and has an end 271 located outside the adapter housing 210. In the state where the adapter housing 210 abuts against the power supply end, the conductive connection member 270 is electrically connected to the power supply end and the control component 250 respectively. In this embodiment, the charger main body 200 is further provided with a second connection portion 240. The second connection portion 240 is disposed on the second housing 260. The second connection portion 240 is used for concave-convex cooperation or snap-fit with the first connection portion 140 of the telescopic data line assembly 100, so that the second housing 260 and the telescopic data line assembly 100 or its first housing 154 are fixed more accurately and stably. In this way, in the fixed state, due to the corresponding positions of the first magnetic member 120 and the second magnetic member 220, the corresponding positions of the first connection portion 140 and the second connection portion 240, and the corresponding positions of the first spring pin connection end 130 and the second spring pin connection end 230, the second spring pin connection end 230 contacts the first spring pin connection end 130 to achieve electrical connection.

[0092] With such a structural design, on the one hand, the wire 112 of the telescopic data line assembly 100 can be pulled out at a larger angle and the wire 112 can be smoothly retracted. Therefore, there is a telescopic data line assembly 100 that can be pulled out at a larger angle, which is particularly suitable for use in an application environment where the position of the in-vehicle charger 900 is limited. On the other hand, the telescopic data line assembly 100 can be detached from the charger main body 200 and used alone, further improving the applicability of the telescopic data line assembly 100.

[0093] Next, continue to combine with Figures 1 to 18, an example is used to illustrate the telescopic data cable assembly 100, the auxiliary pulling device 160, and the vehicle charger 900.

[0094] In one embodiment, the telescopic data cable assembly 100 includes a housing assembly 150, a telescopic data cable 110, and an auxiliary pulling device 160. The telescopic data cable 110 is provided with a wire 112. The housing assembly 150 is provided with an outlet 152. The size of the outlet 152 is larger than the wire width of the wire 112, that is, the wire size, so that the wire 112 can be telescoped from the outlet 152; the auxiliary pulling device 160 includes a fixed seat 161, a spring 162, a pin 163, a cross shaft 164, etc.

[0095] As an example, the fixed seat 161 includes a fixing plate 181, a connecting plate 182, a top plate 183, and a supporting plate 184. One end of the connecting plate 182 is connected to the fixing plate 181, and the other end is connected to the top plate 183. Both sides of the top plate 183 are connected with the supporting plates 184 and are provided with first protrusions 186. The side of the supporting plate 184 away from the top plate 183 is provided with second protrusions 187. A first through hole 191 is provided on the first protrusion 186, and a blind hole 188 is provided on the second protrusion 187. Both ends of the cross shaft 164 are provided with second through holes 192. A sliding groove 189 is provided on the supporting plate 184. The cross shaft 164 passes through the two sliding grooves 189. The pin 163 first passes through the first through hole 191 on the first protrusion 186, then passes through the spring 162, and then passes through the second through hole 192 on the cross shaft 164, and finally is inserted into the blind hole 188 on the second protrusion 187, thus completing the assembly of the auxiliary pulling device 160; the pin 163 can be interference-fitted with the fixed seat 161 or in other ways to be fixed on the fixed seat 161.

[0096] As an example, the auxiliary pulling device 160 further includes a snap ring 165. One end of the pin 163 is provided with a snap ring groove 194. The pin 163 is fixed on the fixed seat 161 by the snap ring 165 being stuck in the snap ring groove 194; when the wire 112 is obliquely pulled out, the wire 112 at the outlet 152 exerts pressure on the cross shaft 164. The cross shaft 164 slides upward in the sliding groove 189 and compresses the spring 162 to ensure the smooth pulling out of the wire 112; when the wire 112 is retracted, the spring 162 returns to its original state, and the cross shaft 164 slides downward in the sliding groove 189 to ensure the smooth retraction of the wire 112.

[0097] In one embodiment, the auxiliary pulling device 160 further includes a roller 166. A third through hole 193 is provided on the roller 166. The roller 166 passes through the transverse shaft 164 and is located between the two support plates 184. When the wire 112 is obliquely pulled out, the wire 112 at the wire outlet 152 applies pressure on the roller 166. The roller 166 drives the transverse shaft 164 to slide upward in the chute 189 and compress the spring 162, ensuring the smooth pulling out of the wire 112. When the wire 112 is recycled, the spring 162 returns to its original state, the transverse shaft 164 slides downward in the chute 189, and drives the rotation of the roller 166, thereby ensuring the smooth recycling of the wire 112. A fixing hole 185 is provided on the fixing base 161, and a threaded hole 116 is provided on the telescopic data cable telescopic mechanism 115. The auxiliary pulling device 160 is fixed on the telescopic data cable telescopic mechanism 115 by screws. The telescopic data cable assembly 100 further includes a port protection member 113. The port protection member 113 is installed on the wire outlet 152 on the housing by means of bonding, snap fit, etc. to protect the wire 112.

[0098] In one embodiment, the housing assembly 150 includes a main housing 153, a first housing 154 and a top cover 155. The main housing 153 and the first housing 154 can be integrally formed, or can be assembled together by snap fit or ultrasonic welding. Or the top cover 155 can be integrally formed with the main housing 153, or can be assembled together by snap fit or ultrasonic welding. The wire outlet 152 can be provided on the main housing 153 or the first housing 154, or can be partially provided on the main housing 153 and the rest on the first housing 154. The telescopic data cable assembly 100 further includes a conductive structure member 170, a first magnetic attachment 120, a first spring pin connection end 130, etc. The conductive structure member 170 includes but is not limited to an FPC cable. The first magnetic attachment 120 can be integrally formed in the first housing 154, or can be assembled on the first housing 154, such as interference fit or bonding with the first housing 154.

[0099] As an example, the first spring pin connection end 130 is a pogopin female end. One end of the first spring pin connection end 130 is electrically connected to one end of the conductive structure member 170, and the other end is exposed outside the first housing 154 of the telescopic data cable assembly 100 through a fourth through hole 156 provided on the first housing 154. The other end of the conductive structure member 170 is electrically connected to the telescopic data cable 110 or its wire 112.

[0100] In one embodiment, the charger body 200 can be detachably connected to the telescopic data cable assembly 100 by magnetic attraction. The charger body 200 is provided with a second magnetic attachment 220 and a second spring pin connection end 230, and the telescopic data cable assembly 100 is provided with a first magnetic attachment 120 and a first spring pin connection end 130. The charger body 200 and the telescopic data cable assembly 100 are detachably connected through the magnetic attraction between the first magnetic attachment 120 and the second magnetic attachment 220, and the charger body 200 and the telescopic data cable assembly 100 are electrically connected through the cooperation between the second spring pin connection end 230 and the first spring pin connection end 130. As an example, the second spring pin connection end 230 is a male pogopin, and the first spring pin connection end 130 is correspondingly a female pogopin.

[0101] Alternatively, the charger body 200 can also be an integrated structure with the telescopic data cable assembly 100, and the whole serves as a vehicle charger 900. The vehicle charger 900 includes a top cover 155, an auxiliary pulling device 160, a telescopic data cable assembly 100, a control component 250, a conductive structure member 170, a main body case 153, a first housing 154, etc. As an example, the control component 250 is a PCB board assembly.

[0102] In one embodiment, the wire 112 of the telescopic data cable assembly 100 is fixed on the telescopic mechanism 115 of the telescopic data cable. One end of the conductive structure member 170 is connected to the wire 112, and the other end is connected to the control component 250, so as to realize the electrical connection between the wire 112 and the control component 250. The telescopic mechanism 115 of the telescopic data cable is provided with screw holes, and the first housing 154 is provided with screw posts. The telescopic mechanism 115 of the telescopic data cable is fixed on the first housing 154 by screws. As an example, a port protection member 113 is also assembled at the wire outlet 152 to protect the wire 112. The main body case 153 and the first housing 154 can be assembled together by snap fit or ultrasonic welding. The top cover 155 can be integrally formed with the main body case 153, or can be assembled with the main body case 153 by snap fit or ultrasonic means.

[0103] When the telescopic data cable assembly 100 is detachably connected to the charger body 200, the wire 112 is pulled out straight as shown in Figure 4 shown, and the wire 112 is pulled out obliquely as shown in Figure 5 shown. When the telescopic data cable assembly 100 is integrally provided with the charger body 200, the wire 112 is pulled out straight as shown in Figure 11 shown, and the wire 112 is pulled out obliquely as shown in Figure 12As shown. Compared with the traditional design where the data cable can only be pulled out straight, it can be seen that the telescopic data cable assembly 100 of the present application can smoothly pull out the wire 112 at multiple angles, so the usage scenarios are more extensive. And when the vehicle charger 900 is in use, the height of its general installation position is approximately at the position of a person's leg. Therefore, the vehicle charger 900 with the telescopic data cable assembly 100 of the present application can smoothly pull out the wire 112 from multiple angles, thus better meeting the usage requirements, being more convenient to use, and having more extensive usage scenarios.

[0104] It should be noted that other embodiments of the present application further include an auxiliary pulling device, a telescopic data cable assembly, and a vehicle charger that can be implemented formed by the combination of the technical features in the above embodiments.

[0105] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification. The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
