Description

Technical Field

[0001] This utility model relates to the field of battery box technology, specifically a battery box. Background Technology

[0002] Chinese patent application No. 202321090142.2 discloses a handle fixing structure and battery box for lithium batteries, including a cover, a handle and a fixing component. The outer side of the cover has a mounting groove, and the bottom of the mounting groove has a first step, two second steps and two third steps. Each second step has a first through hole, and each third step has a second through hole. Two through holes are formed at both ends of the handle. The fixing component includes two fixing members and two fasteners. Each fixing member has a first locking hole and a second locking hole. Each fastener passes through a through hole and abuts against the inner walls of both sides of the mounting groove. Each first locking member passes through a corresponding first through hole and is connected to the inner wall of the corresponding first locking hole.

[0003] In the above technical solution, the handle is installed in the mounting groove and fastened with two fixing parts and two fasteners to securely connect the handle to the cover, thereby saving the external space occupied by the cover. However, in the above technical solution, when the user needs to hold the handle, the gap between the handle and the cover is narrow because the handle is located in the mounting groove. If the user's fingers or palms exceed the standard size, it will be difficult for the user to exert force when using the handle, resulting in poor performance. Utility Model Content

[0004] The purpose of this invention is to provide a battery box that allows the handle to be concealed inside the battery box when not in use and to protrude when needed.

[0005] To achieve the above objectives, this utility model discloses a battery box, including an upper cover and a lower cover that are detachably connected to each other. The upper cover has two symmetrical upper baffles near the lower cover, and the lower cover has a lower baffle corresponding to the upper baffles near the upper cover. The upper baffles and the lower baffles can be interlocked. The upper cover has a handle, which is a metal handle. The metal handle includes a horizontal section located between the two upper baffles and a vertical section located within the upper baffles and connected to both ends of the horizontal section along its length. The vertical section can slide relative to the upper baffles in the vertical direction. The upper baffles have a limiting component for limiting the lifting stroke of the metal handle. When the vertical section of the metal handle is at its lower limit position, the horizontal section of the metal handle is in close contact with the upper surface of the upper cover.

[0006] When the battery box needs to be pulled by the metal handle, the metal handle slides upwards relative to the battery box first, the vertical sections at both ends of the metal handle are located in the upper enclosure and slide relative to each other, until abutting against the limiting assembly, that is, the battery box is started to be pulled.

[0007] The vertical sections of the metal handle are located in the upper enclosure, the metal handle can slide in the upper enclosure and protrude when needed, the handle can be fully unfolded when needed, so that the user does not need to worry about the size of fingers or palms when using the handle, and force can be easily applied, and the handle can be completely embedded and closely attached to the upper surface of the upper end cover when not in use, thereby saving external space, avoiding space occupation and possible collision risk caused by the protruding handle in the traditional design, and improving user experience.

[0008] Preferably, the upper end cover is provided with a lower recess opposite the position of the horizontal section, the opening width of the lower recess is greater than the width of the horizontal section of the metal handle, and the opening length of the lower recess is less than the length of the horizontal section of the metal handle.

[0009] By limiting the opening shape of the lower recess, the user's fingers can be inserted between the horizontal section of the metal handle and the upper surface of the upper end cover, thereby facilitating the user to apply force

[0010] Preferably, the limiting assembly comprises a limiting sliding groove opened on the vertical section in the vertical direction and a cross rod fixedly arranged in the upper enclosure and penetrating the limiting sliding groove, and the diameter of the cross rod is matched with the width of the limiting sliding groove.

[0011] The sliding rod limits the upward stroke of the vertical section of the metal handle, so that the pulling force of the user on the metal handle is transmitted to the battery box through the reaction force of the sliding rod.

[0012] Preferably, at least two limiting sliding grooves are arranged on each vertical section along the width direction of the vertical section, and the cross rod corresponds to the limiting sliding groove one by one.

[0013] The two limiting sliding grooves prevent the relative rotation of the metal handle and the battery box in the width direction of the metal handle when the user pulls the battery box, thereby ensuring the stability of the user when pulling the battery box.

[0014] Preferably, two partitions are arranged in each upper enclosure, and the partitions in each upper enclosure are arranged on both sides of the thickness direction of the vertical section.

[0015] The vertical section of the metal handle is clamped by the partition plate, so that the handle is prevented from shaking in the horizontal direction relative to the battery box, thereby ensuring the stability of the user when pulling the battery box.

[0016] As preferred, the horizontal rod is fixed between the two partition plates in the upper enclosure, thereby reducing the shear stress of the vertical section of the metal handle on the horizontal rod, ensuring the service life of the horizontal rod, and ensuring the use effect of the metal handle.

[0017] As preferred, the horizontal section is provided with an arc surface part in the form of inward shrinkage on both sides in the width direction.

[0018] The arc surface part in the form of inward shrinkage on both sides of the horizontal section of the metal handle increases the gap between the horizontal section of the metal handle and the upper surface of the upper end cover, thereby facilitating the user to pick up the horizontal section of the metal handle and facilitating the user to exert force.

[0019] The metal handle can be fully embedded and tightly attached to the upper surface of the upper end cover when not in use, thereby saving external space, and has the advantages of ensuring the stability and reliability of the structure and realizing the hiding and unfolding functions of the handle.

DETAILED DESCRIPTION

[0026] The utility model will be further described below according to the drawings and specific embodiments.

[0027] By Figure 1As shown, the battery box applied to the scooter disclosed in the embodiment comprises an upper end cover 11, a lower end cover 12 and a socket 23 arranged on the lower end cover 12, which are detachably connected with each other. The upper end cover 11 is provided with a single-layer lip extending downward to the lower end cover 12. The lower end cover 12 is provided with a double-layer lip extending upward to the upper end cover 11. The upper end cover 11 and the lower end cover 12 are inserted and fixed through the single-layer lip and the double-layer lip and the fixing screws arranged on the edge. Figure 5 As shown, the socket 23 can be electrically connected with the plug 22 of the bottom shell 20 of the scooter to be powered. Figure 4 As shown, two upper enclosures 13 are symmetrically arranged on one end of the upper end cover 11 close to the lower end cover 12. A lower enclosure 14 corresponding to the upper enclosure 13 is arranged on one end of the lower end cover 12 close to the upper end cover 11. The upper enclosure 13 and the lower enclosure 14 can be buckled with each other. A handle is arranged on the upper end cover 11, which is a metal handle 18. Figure 3 As shown, the metal handle 18 comprises a horizontal section 181 between the two upper enclosures 13 and vertical sections 182 arranged in the upper enclosures 13 and connected to both ends of the horizontal section 181 in the length direction. The width direction of the horizontal section 181 is provided with arc-shaped parts 1811 which are inwardly recessed. Two partitions 15 are arranged in each of the upper enclosures 13. The partitions 15 in each of the upper enclosures 13 are arranged on both sides of the thickness direction of the vertical sections 182. An opening 16 is arranged on the upper end cover 11 for the vertical sections 182 to be inserted between the partitions 15. The vertical sections 182 can slide in the vertical direction between the partitions 15.

[0028] As shown, the upper enclosure 13 is provided with a limiting assembly for limiting the lifting stroke of the metal handle 18. The limiting assembly comprises at least two limiting sliding grooves 1821 arranged in the vertical direction on the vertical sections 182 and arranged in the width direction of the vertical sections 182. The horizontal section 181 of the metal handle 18 is close to the upper surface of the upper end cover 11 when the vertical sections 182 of the metal handle 18 are in the lower limit position. Figure 2 The upper end cover 11 is provided with a lower recess 19 opposite to the position of the horizontal section 181. The opening 16 of the lower recess 19 is wider than the width of the horizontal section 181 of the metal handle 18. The length of the opening 16 of the lower recess 19 is smaller than the length of the horizontal section 181 of the metal handle 18, thereby increasing the gap between the horizontal section 181 and the upper surface of the upper end cover 11, so as to facilitate the user to apply force.

[0029] The horizontal section 181 of the metal handle 18 is close to the upper surface of the upper end cover 11 when the vertical sections 182 of the metal handle 18 are in the lower limit position.

[0030] The horizontal section 181 of the metal handle 18 is close to the upper surface of the upper end cover 11 when the vertical sections 182 of the metal handle 18 are in the lower limit position.

[0031] When the user needs to use the battery box, manually put the battery box into the mounting groove 21 of the scooter bottom shell 20, and make the socket 23 of the battery box electrically connected with the plug 22 at the bottom of the mounting groove 21, that is, the battery box starts to work. At this time, the vertical section 182 of the metal handle 18 of the battery box penetrates the opening 16 and the upper barrier 13 and is located at the lower limit position in the lower barrier 14, and the horizontal section 181 of the metal handle 18 is close to the upper surface of the upper end cover 11. At this time, the handle is in a non-use state, thereby saving external space. When the user needs to disassemble the battery box, pass the metal handle 18 through the lower recess 19 of the upper end cover 11, and pull the horizontal section 181 of the metal handle 18 upward. The vertical section 182 of the metal handle 18 moves upward. When the crossbar 17 slides relative to the metal handle 18 to the bottom of the limiting sliding groove 1821, at this time, the metal handle 18 drives the battery box to move upward synchronously through the crossbar 17. The user takes out the battery box from the mounting groove 21 of the scooter bottom shell 20 through the metal handle 18, and separates the battery box from the plug 22, thereby realizing the quick disassembly of the battery box.
