Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a jumper connector and a vehicle. Background Technology

[0002] Currently, when a vehicle's battery is dead, an external power source is connected to the battery via the vehicle's jumper connector, enabling emergency power-up and allowing the vehicle to start normally. However, because the positive and negative terminals on the jumper connector are close together, users often habitually pull out or insert the external power source simultaneously onto the connector's sleeve, which can easily cause a short circuit and poses a safety hazard. Utility Model Content

[0003] Therefore, this application provides a jumper connector that reduces the occurrence of users simultaneously plugging and unplugging the positive and negative terminals of the external power supply, reduces the occurrence of short circuits between the positive and negative terminals of the external power supply, and improves safety.

[0004] This application also provides a vehicle including the aforementioned jumper connector.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a jump-start connector for electrical connection with a vehicle battery, comprising: a jump-start sleeve, wherein there are two jump-start sleeves, the two jump-start sleeves are separate parts and spaced apart, each jump-start sleeve has a terminal hole, one of the two jump-start sleeves is adapted to connect to the positive terminal of an external power source, and the other is adapted to connect to the negative terminal of an external power source.

[0007] The jumper connector provided in this application embodiment consists of two jumper sleeves, which are separate and spaced apart. Each jumper sleeve has a terminal hole. One of the two jumper sleeves is adapted to connect to the positive terminal of an external power supply, and the other is adapted to connect to the negative terminal of an external power supply. This allows for adjusting the distance between the two jumper sleeves and changing their positions so that the positive and negative terminals of the external power supply are inserted in opposite directions. This reduces the occurrence of users simultaneously plugging and unplugging the positive and negative terminals of the external power supply, reduces the occurrence of short circuits between the positive and negative terminals, and improves safety.

[0008] In one possible implementation of this application, the jumper sleeve includes: a sleeve body having a locking mechanism adapted to lock the positive or negative terminal of the external power supply, and the terminal hole being provided on the sleeve body; and a snap-fit ​​structure detachably connected to the sleeve body for driving the locking mechanism to lock the positive or negative terminal of the external power supply.

[0009] In one possible implementation of this application, the sheath body has slots on both sides along a first direction, the slots extend along a second direction, and each slot has a trigger mechanism on its bottom wall. The trigger mechanism cooperates with the locking mechanism to drive the locking mechanism to lock the positive or negative terminal of the external power supply. The latching structure includes: a main body portion located on one side of the sheath body along a third direction; and two latch portions corresponding to the two slots. The two latch portions are respectively connected to both sides of the main body portion along the first direction and located at one end of the main body portion facing the sheath body. The two latch portions are respectively used to trigger the two trigger mechanisms. The first direction, the second direction, and the third direction are mutually perpendicular.

[0010] In one possible implementation of this application, the sheath body has a limiting groove on one side along a third direction, and at least a portion of the body portion is disposed in the limiting groove.

[0011] In one possible implementation of this application, the side of the main body facing away from the sheath body has a groove; and / or, the end of the main body facing away from the sheath body has a clamping portion extending along the second direction.

[0013] In one possible implementation of this application, the latching part includes: a connecting part, one end of which is connected to the main body part; a first latching protrusion, which is connected to the end of the connecting part opposite to the main body part and is adapted to be latched in the latching groove; and a second latching protrusion, which is connected to the end of the connecting part opposite to the main body part and protrudes toward the first limiting plate along the second direction, and is adapted to abut against the first limiting plate.

[0014] In one possible implementation of this application, along the direction from the main body to the sheath body, the end face of the connecting portion facing the second limiting plate extends obliquely toward the first limiting plate.

[0015] In one possible implementation of this application, the first limiting plate has a third latching protrusion that protrudes toward the second limiting plate and is adapted to abut against the latching portion.

[0016] Secondly, embodiments of this application provide a vehicle including the aforementioned jumper connector.

[0017] The vehicle provided in this application embodiment, by setting the aforementioned jumper connector, has two jumper sleeves, which are separate and spaced apart. Each jumper sleeve has a terminal hole. One of the two jumper sleeves is adapted to connect to the positive terminal of an external power supply, and the other is adapted to connect to the negative terminal of an external power supply. This allows for adjusting the distance between the two jumper sleeves and changing their positions so that the positive and negative terminals of the external power supply are plugged in opposite directions. This reduces the occurrence of users simultaneously plugging and unplugging the positive and negative terminals of the external power supply, reduces the occurrence of short circuits between the positive and negative terminals of the external power supply, and improves safety.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0032] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0033] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0034] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0035] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0036] The following is for reference. Figures 1-6 This application describes a jumper connector 100 provided in an embodiment.

[0037] Firstly, such as Figures 1-6 As shown, this application embodiment provides a jumper connector 100, including a jumper sleeve 10.

[0038] Specifically, refer to Figures 1-6 The jumper connector 100 is used for electrical connection with the vehicle's battery. There are two jumper sleeves 10, which are separate and spaced apart. Each jumper sleeve 10 has a terminal hole 11. One of the two jumper sleeves 10 is adapted to connect to the positive terminal of an external power source, and the other is adapted to connect to the negative terminal of an external power source.

[0039] It is understandable that, since the two jumper sleeves 10 are separate and spaced apart, the spacing between the two jumper sleeves 10 and their position on the vehicle can be freely adjusted as needed. For example, the openings of the terminal holes 11 of the two jumper sleeves 10 can be set opposite to each other along the width direction of the vehicle, that is, the positive and negative terminals of the external power supply are plugged in in opposite directions along the width direction of the vehicle, or the two jumper sleeves 10 can have an angle between them.

[0040] Therefore, by using two separate jumper sleeves 10, the distance between the two jumper sleeves 10 can be adjusted, and the positions of the two jumper sleeves 10 can be changed so that the positive and negative terminals of the external power supply are plugged in opposite directions. This reduces the occurrence of users plugging and unplugging the positive and negative terminals of the external power supply at the same time, reduces the occurrence of short circuits between the positive and negative terminals of the external power supply, and improves safety.

[0041] In addition, since the two jumper sleeves 10 are separate components and spaced apart, compared to making the two jumper sleeves 10 into one piece and setting them far apart, the jumper sleeves 10 use less material, making them more economical and lightweight. At the same time, since the two jumper sleeves 10 are separate components, when one of the jumper sleeves 10 is damaged, it can be repaired individually, saving maintenance costs.

[0042] The jumper connector 100 provided in this application embodiment consists of two jumper sleeves 10, which are separate and spaced apart. Each jumper sleeve 10 has a terminal hole 11. One of the two jumper sleeves 10 is adapted to connect to the positive terminal of an external power supply, and the other is adapted to connect to the negative terminal of an external power supply. This allows for adjusting the distance between the two jumper sleeves 10 and changing their positions so that the positive and negative terminals of the external power supply are connected in opposite directions. This reduces the occurrence of users simultaneously plugging and unplugging the positive and negative terminals of the external power supply, reduces the occurrence of short circuits between the positive and negative terminals of the external power supply, and improves safety.

[0043] In one possible implementation of this application, such as Figures 1-6 As shown, the jumper sleeve 10 includes: a sleeve body 1 and a snap-fit ​​structure 2. The sleeve body 1 has a locking mechanism (such as a snap ring assembly) for locking the positive or negative terminal of the external power supply. A terminal hole 11 is provided on the sleeve body 1. The snap-fit ​​structure 2 is detachably connected to the sleeve body 1 and is used to drive the locking mechanism to lock the positive or negative terminal of the external power supply.

[0044] It should be noted that the locking mechanism in the positive terminal jumper sleeve 10 is suitable for locking the positive terminal of the external power supply, and the locking mechanism in the negative terminal jumper sleeve 10 is suitable for locking the negative terminal of the external power supply.

[0045] Understandably, the positive or negative terminal of the external power supply is first inserted into the terminal hole 11 of the jumper sleeve 10. When the snap-fit ​​structure 2 is connected to the sleeve body 1, the locking mechanism can be triggered to lock the positive or negative terminal inserted into the terminal hole 11, thereby improving the reliability of the connection between the positive or negative terminal and the jumper sleeve 10 and thus improving the reliability and stability of the electrical connection of the jumper connector 100.

[0046] When it is necessary to remove the positive or negative terminal, first remove the locking structure 2 from the sheath body 1, thereby releasing the positive or negative terminal of the locking mechanism (the locking mechanism can be reset and unlocked through a structure such as a spring reset component), so that the positive or negative terminal can be removed from the sheath body 1.

[0047] Furthermore, the operation of the locking mechanism, as well as the locking and releasing terminals, is conventional technology well known to those skilled in the art and will not be described in detail here.

[0048] In one possible implementation of this application, such as Figure 1 , Figure 5 and Figure 6 As shown, the sheath body 1 has slots 12 on both sides along the first direction, and the slots 12 extend along the second direction. Each slot 12 has a trigger mechanism on its bottom wall. The trigger mechanism cooperates with the locking mechanism to drive the locking mechanism to lock the positive or negative terminal of the external power supply.

[0049] The snap-fit ​​structure 2 includes a main body 21 and a snap-fit ​​part 22. The main body 21 is located on one side of the sheath body 1 along the third direction. The snap-fit ​​part 22 consists of two parts corresponding to the two slots 12. The two snap-fit ​​parts 22 are respectively connected to the two sides of the main body 21 along the first direction and are located at the end of the main body 21 facing the sheath body 1. The two snap-fit ​​parts 22 are respectively used to trigger two triggering mechanisms. The first direction, the second direction and the third direction are perpendicular to each other.

[0050] It is understandable that the main body 21 is relatively fixed to the sheath body 1, thereby achieving reliable connection between the sheath body 1 and the snap-fit ​​structure 2. Two snap-fit ​​parts 22, arranged opposite each other in the first direction on the main body 21, are respectively located in two slots 12. On the one hand, the two snap-fit ​​parts 22 arranged opposite each other in the first direction fix the snap-fit ​​structure 2 and the sheath body 1 relative to each other in the first direction. On the other hand, the slots 12 fix the snap-fit ​​structure 2 and the sheath body 1 relative to each other in the third direction, and the locking mechanism is driven by a trigger mechanism to lock the positive or negative terminal of the external power supply.

[0051] Meanwhile, when it is necessary to disassemble the snap-fit ​​structure 2, the user can manually drive the two snap-fit ​​parts 22 to move in the first direction away from each other, so that both snap-fit ​​parts 22 leave the slot 12, thereby disassembling the snap-fit ​​structure 2 and releasing the positive or negative terminal of the external power supply from the locking mechanism.

[0052] Furthermore, the triggering mechanism can be a pressure sensor and a motor. The pressure sensor is located on the bottom wall of the slot 12, and the motor's drive shaft cooperates with the locking mechanism. The pressure sensor and the motor are communicatively connected. When the pressure sensor detects a certain pressure value, it controls the motor to drive the locking mechanism to lock the terminals. When the pressure sensor detects a pressure value less than a certain value, it controls the motor to drive the locking mechanism to release the terminals.

[0053] Furthermore, the triggering mechanism can be an unlocking block, which cooperates with the locking mechanism. The unlocking block is movably disposed on the sheath body 1 along a first direction, with a portion of the unlocking block protruding from the bottom wall of the slot 12. When the latching part 22 abuts against the unlocking block, the latching part 22 drives the unlocking block to move toward the inside of the sheath body 1, thereby driving the locking mechanism to lock the terminal. When the latching part 22 leaves the slot 12, the unlocking block resets under the action of a reset member (reset spring, etc.), thereby releasing the locking mechanism from the terminal. However, the structure of the triggering mechanism in this application is not limited to this and can also be in other forms.

[0054] In one possible implementation of this application, such as Figures 1-4 As shown, the sheath body 1 has a limiting groove 13 on one side along a third direction, and at least a portion of the main body 21 is disposed in the limiting groove 13. This improves the connection reliability between the sheath body 1 and the snap-fit ​​structure 2.

[0055] In one possible implementation of this application, such as Figures 1-4 As shown, the side of the main body 21 facing away from the sheath body 1 has a groove 211; it can be understood that the groove 211 reduces the weight and cost of the snap-fit ​​structure 2 on the one hand, and facilitates the user to disassemble the snap-fit ​​structure 2 through the groove 211 on the other hand.

[0056] In one possible implementation of this application, such as Figures 1-4 As shown, the end of the main body 21 facing away from the sheath body 1 has a clamping part 212 extending in a second direction. This allows the user to easily disassemble the snap-fit ​​structure 2 using the clamping part 212.

[0057] In one possible implementation of this application, such as Figures 1-5 As shown, the sheath body 1 has a first limiting plate 14 and a second limiting plate 15, which are respectively located on both sides of the slot 12 along its length. The locking structure 2 is located between the first limiting plate 14 and the second limiting plate 15. This further restricts the movement of the locking structure 2 in the second direction, thereby further improving the connection reliability between the sheath body 1 and the locking structure 2, and thus improving the locking reliability of the positive or negative terminal on the sheath body 1.

[0058] In one possible implementation of this application, such as Figures 1-5As shown, the latching part 22 includes: a connecting part 221, a first latching protrusion 222 and a second latching protrusion 223. One end of the connecting part 221 is connected to the main body part 21. The first latching protrusion 222 is connected to the end of the connecting part 221 that is away from the main body part 21 and is adapted to be latched in the latching groove 12. The second latching protrusion 223 is connected to the end of the connecting part 221 that is away from the main body part 21 and protrudes towards the first limiting plate 14 in a second direction and is adapted to abut against the first limiting plate 14.

[0059] Understandably, the first latching protrusions 222, which are arranged opposite each other along the first direction, can restrict the movement of the latching parts 22 in the first direction and also restrict their movement in the third direction. The second latching protrusion 223 restricts the movement of the latching parts 22 towards the first limiting plate 14, thereby further improving the connection reliability between the latching structure 2 and the sheath body 1, and thus improving the locking reliability of the positive or negative terminal on the sheath body 1.

[0060] In one possible implementation of this application, such as Figure 5 As shown, along the direction from the main body 21 to the sheath body 1, the end face of the connecting part 221 facing the second limiting plate 15 extends obliquely toward the first limiting plate 14. This facilitates the second locking protrusion 223 to abut against the first limiting plate 14, thereby further improving the connection reliability between the locking structure 2 and the sheath body 1, and thus improving the locking reliability of the positive or negative terminal on the sheath body 1.

[0061] In one possible implementation of this application, such as Figure 5 As shown, the first limiting plate 14 has a third locking protrusion 141, which protrudes towards the second limiting plate 15 and is adapted to abut against the latching part 22. It can be understood that the provision of the third locking protrusion 141 further restricts the movement of the latching part 22 towards the first limiting plate 14, thereby further improving the connection reliability between the latching structure 2 and the sheath body 1, and thus improving the locking reliability of the positive or negative terminal on the sheath body 1.

[0062] Furthermore, such as Figure 5 As shown, along the direction from the main body 21 to the sheath body 1, the end face of the connecting part 221 extends vertically toward the first limiting plate 14, thereby making the third locking protrusion 141 and the connecting part 221 reliably stop against each other.

[0063] Furthermore, such as Figure 5As shown, the third latching protrusion 141 is located on the side of the second latching protrusion 223 facing the main body 21. Along the direction from the main body 21 to the sheath body 1, the end face of the third latching protrusion 141 facing away from the second latching protrusion 223 is inclined toward the second limiting plate 15. Thus, the end face of the third latching protrusion 141 facing away from the second latching protrusion 223 forms a movable guide slope, which facilitates the latching part 22 to move along the movable guide slope and be locked in the slot 12.

[0065] Secondly, embodiments of this application provide a vehicle including the aforementioned jumper connector 100.

[0066] The vehicle provided in this application embodiment, by setting the aforementioned jumper connector 100, has two jumper sleeves 10, which are separate and spaced apart. Each jumper sleeve 10 has a terminal hole 11. One of the two jumper sleeves 10 is adapted to connect to the positive terminal of an external power supply, and the other is adapted to connect to the negative terminal of an external power supply. This allows for adjusting the distance between the two jumper sleeves 10 and changing their positions so that the positive and negative terminals of the external power supply are plugged in opposite directions. This reduces the occurrence of users simultaneously plugging and unplugging the positive and negative terminals of the external power supply, reduces the occurrence of short circuits between the positive and negative terminals of the external power supply, and improves safety.
