Description
Technical Field
[0001] This utility model relates to the field of power supply equipment technology, specifically to a mobile contact power supply device. Background Technology
[0002] A sliding contact power supply device, also known as a sliding contact power supply device, is a power transmission device for supplying power to mobile equipment. During the movement of the equipment, it transmits electrical energy stably to the equipment through sliding contact, ensuring the normal operation of the equipment.
[0003] The mobile contact power supply device includes a laid guide rail containing a copper conductor. The guide rail makes sliding contact with the sliding brush of the current collection component on the equipment, and stably transmits electrical energy as the equipment moves.
[0004] Specific application scenarios include powering sorting vehicles in express delivery distribution centers. The sorting vehicle moves along the guide rail, and the sliding brush on the sorting vehicle slides and contacts the guide rail, moving with the sorting vehicle and synchronously and stably transmitting electrical energy.
[0005] In related technologies, when the sliding brush and the guide rail are connected, the sliding brush is usually directly inserted into the groove of the guide rail from above. This method can easily cause the guide rail and the sliding brush to collide and be damaged. In addition, the direct insertion method makes it difficult to ensure the precise alignment of the sliding brush and the guide rail, resulting in poor cooperation between the sliding brush and the guide rail. It is difficult to ensure stable contact between the sliding brush and the guide rail, which affects the stability of power supply. Utility Model Content
[0006] In view of this, the present invention provides a mobile contact power supply device to solve the problem that when the sliding brush and the guide rail are connected, the sliding brush is usually directly forcefully inserted from above the guide rail, which makes the guide rail and the sliding brush easily damaged, and the cooperation effect between the sliding brush and the guide rail is poor, affecting the stability of power supply.
[0007] This utility model provides a mobile contact power supply device, comprising: a guide rail with a recessed groove extending along the x-direction; a sliding brush slidably engaged with the groove; and a guide member comprising a base and a guide groove recessed in the base. Two guide members are provided, each disposed at one end of the guide rail, with the end of the guide rail engaging with a portion of the guide groove. An opening is provided at the end of the guide groove furthest from the guide rail.
[0008] Beneficial effects: By setting guide members on opposite sides of the guide rail along its extension direction, and providing guide grooves on the guide members, the guide rail and a portion of the guide groove engage with each other, connecting the sliding groove on the guide rail to the guide groove. Simultaneously, the guide groove has an opening at its end away from the guide rail. Therefore, when the sliding brush connects with the guide rail, no force needs to be applied above the guide rail to engage the sliding brush. The operator can directly use the guide members to slide the sliding brush from the opening of the guide member into the guide groove, allowing it to slide smoothly along the guide groove towards the guide rail. Because the guide rail and a portion of the guide groove engage, the sliding brush can slide directly into the sliding groove of the guide rail under the guidance of the guide groove, preventing damage to the sliding brush and guide rail during the engagement process. At the same time, the guide groove guides the position of the sliding brush, preventing misalignment between the sliding brush and the guide rail, ensuring excellent engagement between the sliding brush and the guide rail, preventing poor contact between the conductors of the sliding brush and the guide rail, and thus ensuring power supply stability.
[0009] In one optional embodiment, the guide groove includes a first guide groove and a slot, one end of the first guide groove is connected to the slot, and the other end is provided with the opening; the guide rail is engaged with the slot.
[0010] Beneficial effects: The guide groove includes a first guide groove and a slot. The guide rail and the slot are engaged to ensure a stable connection between the guide rail and the guide component. When the sliding brush is engaged with the guide rail, it enters the first guide groove from the opening and slides along the first guide groove until it enters the groove of the guide rail. The first guide groove and the groove extend in the same direction, both extending along the x-axis, ensuring that the sliding brush slides smoothly into the guide rail and ensuring stable power supply to the small-sized guide rail. At the same time, due to the good fit, the sliding brush can slide at high speed on the guide rail, ensuring continuous power supply.
[0011] In one optional embodiment, the guide rail includes a conductor and a track connected together, both of which extend along the x-direction; the track has two opposing side plates, which are respectively disposed on opposite sides of the conductor, and the side plates protrude relative to the conductor to form the groove between the conductor and the two side plates.
[0012] Beneficial effects: A groove is provided at the track, extending along the x-direction. The conductor is installed on the inner bottom side of the track groove. Two side plates form the two side walls of the groove, located on opposite sides of the conductor, and enclosing a sliding groove between the conductor and the two side plates. The bottom side of the sliding brush engages with the sliding groove, ensuring that the sliding brush can maintain good contact with the conductor even when sliding at high speed, ensuring stable conductivity between the conductor and the sliding brush, and thus ensuring the power supply stability of the moving contact power supply device.
[0013] In one optional embodiment, the two ends of the conductor extend outward relative to the track to form protruding sections; the end of the track engages with the slot, and the protruding sections extend into the first guide groove.
[0014] Beneficial effects: The two ends of the conductor extend outward relative to the track to form an extension section, and the end of the track engages with the slot. The extension section naturally extends forward and is placed in the first guide groove, which facilitates the sliding brush to smoothly enter the sliding groove of the conductor through the first guide groove, improves the matching accuracy between the sliding brush and the guide rail, and further improves the stability of the contact between the sliding brush and the conductor when sliding at high speed.
[0015] In one optional embodiment, a limiting part is provided inside the end of the card slot near the first guide groove. The limiting part protrudes from the inner wall of the card slot, and a groove is formed in the limiting part. The end of the track abuts against the limiting part and is limited. The protruding section passes through the groove and extends into the first guide groove.
[0016] In one alternative embodiment, a connecting groove is recessed at the conductor, and an abutting portion is provided on the bottom side of the sliding brush. The abutting portion is adapted to the shape of the connecting groove so that the abutting portion abuts and engages with the connecting groove.
[0017] Beneficial effects: The shape of the connecting groove is adapted to the shape of the abutment part on the bottom side of the sliding brush, ensuring stable contact between the abutment part and the connecting groove, and enhancing the contact stability between the sliding brush and the conductor; furthermore, the shape of the connecting groove can be, but is not limited to, V-shaped or U-shaped, to increase the contact area between the sliding brush and the conductor, thereby further improving the contact stability between the sliding brush and the conductor, and thus improving the conductivity of the sliding brush when sliding at high speed.
[0018] In one alternative embodiment, at least a portion of the substrate is inclined downward toward the side away from the guide rail.
[0019] In one optional embodiment, the guide rails are provided in multiple ways, and the multiple guide rails are arranged at intervals and in parallel; the guide grooves are provided in multiple ways, and the multiple guide grooves are arranged at intervals at the guide member, and the guide rails and the guide grooves are connected in a one-to-one correspondence.

[0044] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0045] The following is combined with Figures 1 to 11 The following describes embodiments of the present invention.
[0046] According to an embodiment of the present invention, a mobile contact power supply device is provided, comprising: a guide rail 1, wherein a groove 11 is recessed in the guide rail 1 and extends along the x-direction; a sliding brush 2, which is slidably engaged with the groove 11; and a guide member 3, wherein the guide member 3 comprises a base 31 and a guide groove 32 recessed in the base 31; wherein two guide members 3 are provided, and the two guide members 3 are respectively disposed at both ends of the guide rail 1, and the end of the guide rail 1 is engaged with a portion of the groove of the guide groove 32; and an opening 33 is provided at the end of the guide groove 32 away from the guide rail 1.
[0047] It should be noted that in the relevant technology, when the sliding brush 2 and the guide rail 1 are connected, the sliding brush 2 is usually directly inserted into the guide rail 1 from above. The guide rail 1 and the sliding brush 2 are easily damaged, and the cooperation between the sliding brush 2 and the guide rail 1 is poor, which affects the stability of power supply.
[0048] In this embodiment, guide members 3 are provided on opposite sides of the guide rail 1 along its extension direction. Guide members 3 have guide grooves 32, and the guide rail 1 is engaged with a portion of the guide groove 32, allowing the sliding groove 11 on the guide rail 1 to communicate with the guide groove 32. Simultaneously, the guide groove 32 has an opening 33 at its end away from the guide rail 1. Therefore, when the sliding brush 2 is connected to the guide rail 1, it is not necessary to apply force above the guide rail 1 to engage the sliding brush 2. The operator can directly use the guide member 3 to slide the sliding brush 2 from the opening 33 of the guide member 3 into the guide groove 32, and then along the guide... The groove 32 slides smoothly towards the guide rail 1. Due to the engagement between the guide rail 1 and part of the groove of the guide groove 32, the sliding brush 2 can slide directly into the groove 11 of the guide rail 1 under the guidance of the guide groove 32, preventing damage to the sliding brush 2 and the guide rail 1 during the engagement process. At the same time, the guide groove 32 can guide the position of the sliding brush 2, prevent misalignment between the sliding brush 2 and the guide rail 1, ensure good engagement between the sliding brush 2 and the guide rail 1, prevent poor contact between the conductor 12 of the sliding brush 2 and the guide rail 1, and thus ensure power supply stability.
[0049] Preferably, the opening 33 may be, but is not limited to, open outward in the direction away from the guide rail 1, that is, the diameter of the opening 33 is larger than the diameter of the groove on the side of the guide groove 32 near the guide rail 1, which facilitates the sliding brush 2 to enter the guide groove 32.
[0050] In some embodiments, combined with Figure 5 As shown, the guide groove 32 includes a first guide groove 321 and a slot 322. One end of the first guide groove 321 is connected to the slot 322, and the other end is provided with the opening 33. The guide rail 1 is engaged with the slot 322.
[0051] In this embodiment, the guide groove 32 includes a first guide groove 321 and a slot 322. The guide rail 1 is engaged with the slot 322, so that the guide rail 1 and the guide member 3 are stably connected. When the sliding brush 2 is engaged with the guide rail 1, it enters the first guide groove 321 from the opening 33 and slides along the first guide groove 321 until it enters the slide groove 11 of the guide rail 1. The first guide groove 321 and the slide groove 11 extend in the same direction, both extending along the x-direction, to ensure that the sliding brush 2 slides smoothly into the guide rail 1, to ensure stable power supply to the small-sized guide rail 1, and at the same time, due to the good fit, to ensure that the sliding brush 2 can slide at high speed on the guide rail 1, to ensure continuous power supply.
[0052] In some embodiments, combined with Figure 3 As shown, the guide rail 1 includes a conductor 12 and a track 13 connected together. Both the conductor 12 and the track 13 extend along the x-direction. The track 13 has two side plates 131 arranged opposite to each other. The two side plates 131 are respectively arranged on opposite sides of the conductor 12, and the side plates 131 protrude relative to the conductor 12 to form the groove 11 between the conductor 12 and the two side plates 131.
[0053] In this embodiment, a groove is provided at the track 13, which extends along the x-direction. The conductor 12 is installed on the inner bottom side of the groove of the track 13. Two side plates 131 are the two side walls of the groove, located on opposite sides of the conductor 12, and forming a sliding groove 11 between the conductor 12 and the two side plates 131. The bottom side of the sliding brush 2 is engaged with the sliding groove 11 to ensure that the sliding brush 2 can still maintain good contact with the conductor 12 when sliding at high speed, ensuring stable conductivity between the conductor 12 and the sliding brush 2, thereby ensuring the power supply stability of the moving contact power supply device.
[0054] Optionally, the conductor 12 can be made of, but is not limited to, copper, which has good conductivity and wear resistance, ensuring stable conductivity during long-term use.
[0055] In some embodiments, combined with Figure 3 As shown, the two ends of the conductor 12 extend out relative to the track 13 to form an extension section 121; the end of the track 13 is engaged with the slot 322, and the extension section 121 extends into the first guide groove 321.
[0056] In this embodiment, the two ends of the conductor 12 extend outward relative to the track 13 to form an extension section 121, and the end of the track 13 engages with the slot 322. The extension section 121 naturally extends forward and is placed in the first guide groove 321, which facilitates the sliding brush 2 to smoothly enter the sliding groove 11 of the conductor 12 through the guidance of the first guide groove 321, thereby improving the matching accuracy between the sliding brush 2 and the guide rail 1 and further improving the stability of the contact between the sliding brush 2 and the conductor 12 when sliding at high speed.
[0057] In some embodiments, combined with Figure 6 As shown, the slot 322 has a limiting part 323 inside one end near the first guide groove 321. The limiting part 323 protrudes from the inner wall of the slot 322, and a groove 324 is formed in the limiting part 323. The end of the track 13 abuts against the limiting part 323 and is limited. The protruding section 121 passes through the groove 324 and extends into the first guide groove 321.
[0058] In this embodiment, the limiting part 323 is disposed inside the slot 322 and protrudes from the inner wall of the slot 322, so that the end of the limiting part 323 near the guide rail 1 abuts against the end of the track 13 for limiting and fixing, thereby effectively limiting and fixing the end of the track 13 and preventing the track 13 from shifting in the x direction; on this basis, a groove 324 is formed in the recessed side of the limiting part 323 away from the slot 322. Since the protruding section 121 protrudes from the end of the track 13, the protruding section 121 extends into the first guide groove 321 after passing through the groove 324, which facilitates the sliding brush 2 to smoothly enter the sliding groove 11 of the conductor 12 through the guidance of the first guide groove 321, thereby improving the matching accuracy between the sliding brush 2 and the guide rail 1.
[0059] In some embodiments, combined with Figure 3 As shown, a connecting groove 122 is recessed at the conductor 12, and an abutting part 21 is provided on the bottom side of the sliding brush 2. The shape of the abutting part 21 is adapted to the connecting groove 122 so that the abutting part 21 abuts and engages with the connecting groove 122.
[0060] In this embodiment, the shape of the connecting groove 122 is adapted to the shape of the abutment portion 21 on the bottom side of the sliding brush 2, ensuring stable contact between the abutment portion 21 and the connecting groove 122, and enhancing the contact stability between the sliding brush 2 and the conductor 12. Furthermore, the shape of the connecting groove 122 can be, but is not limited to, V-shaped or U-shaped, to increase the contact area between the sliding brush 2 and the conductor 12, thereby further improving the contact stability between the sliding brush 2 and the conductor 12, and thus improving the conductivity of the sliding brush 2 when sliding at high speed.
[0061] In some embodiments, combined with Figure 5 As shown, at least a portion of the substrate 31 is inclined downward toward the side away from the guide rail 1.
[0062] In this embodiment, the portion of the substrate 31 near the first guide groove 321 is inclined so that the first guide groove 321 on it is inclined downward toward the side away from the guide rail 1. As a result, when the sliding brush 2 enters the first guide groove 321, it is guided by the inclined surface of the substrate 31 and smoothly slides into the groove 11 of the conductor 12, thereby improving the operating efficiency and conductivity of the sliding brush 2. The specific inclination angle of the substrate 31 can be determined according to the actual application requirements.
[0063] In some embodiments, combined with Figure 1 As shown, the guide rail 1 has multiple rails, which are spaced apart and arranged in parallel; the guide groove 32 has multiple grooves, which are spaced apart at the guide member 3, and the guide rail 1 and the guide groove 32 are connected in a one-to-one correspondence.
[0064] In this embodiment, multiple guide rails 1 are arranged in a one-to-one correspondence with multiple guide grooves 32. Multiple sliding brushes 2 are also provided, and the multiple sliding brushes 2 are respectively arranged on multiple guide rails 1. At least one sliding brush 2 is provided on each guide rail 1. The sliding brush 2 on each guide rail 1 is guided by the corresponding guide groove 32 to ensure that each sliding brush 2 is precisely matched with the corresponding guide rail 1, thereby improving the stability and conductivity efficiency of the moving contact power supply device. The multiple guide rails 1 are arranged in parallel, which effectively disperses the current load and extends the service life.
[0065] In some embodiments, combined with Figure 2 As shown, the mobile contact power supply device also includes a current collector 4, which is connected to the sliding brush 2.
[0066] In this embodiment, the current collector 4, also known as the current collector arm or current collector, is electrically connected to the sliding brush 2 and the external electrical equipment, serving to transmit power. The current collector 4 is an existing component and comes in various forms, such as... Figure 9 or Figure 10 The current collector 4 in the middle can be installed according to the needs in actual production; through the cooperation of the guide rail 1 and the sliding brush 2, while ensuring power supply, it avoids the problem of cable tangling or breakage caused by the movement of external electrical equipment, thus ensuring the efficient and stable operation of the power supply system.
[0067] In some embodiments, combined with Figure 2 As shown, the mobile contact power supply device also includes a power supply component 5, which is connected to the guide rail 1 and electrically connected to the conductor 12.
[0068] In this embodiment, the power supply component 5 is electrically connected to the conductor 12, and the power supply component 5 is also connected to an external power source via a wire to transmit current to the external mobile device through the conductor 12 and the sliding brush 2. The mobile contact power supply device also includes a fixing clip 6, which is used to fix the guide rail 1 to the external support structure. The fixing clip 6 includes multiple fixing slots, and the multiple guide rails 1 are respectively snapped into the fixing slots to ensure that the guide rails 1 are stably installed on the external support structure and to prevent the guide rails 1 from shifting due to vibration.
[0069] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation.
