Description

Technical Field

[0001] This utility model relates to the field of battery charging equipment technology, specifically to a multi-station dedicated charging base for logistics handheld air guns and a battery housing adaptation structure. Background Technology

[0002] In the logistics industry, handheld air inflators are widely used for inflating cushioning bags, and the charging efficiency and stability of their rechargeable batteries have a significant impact on the operational process. Currently, the dedicated rechargeable batteries used in logistics handheld air inflators face the dual challenges of compatibility and connectivity during the charging process.

[0003] On the one hand, due to the lack of dedicated multi-station charging docks, when multiple batteries need to be charged at the same time, multiple independent charging carriers can only be relied upon. This not only occupies a lot of space, but also results in the decentralized management of the charging status of each battery, which is inefficient.

[0004] On the other hand, existing charging connection methods have serious defects. There is no precise guidance and locking structure between the battery and the charging carrier, which makes it easy for the battery to deviate when inserted, making it difficult to accurately connect the charging contacts, and thus causing problems such as poor contact and charging interruption.

[0005] Meanwhile, in complex logistics operation environments, external factors such as equipment vibration and unintentional touch by personnel can easily cause batteries that are not securely locked to fall off the charging carrier, making it impossible to guarantee the continuity and stability of the charging process.

[0006] Furthermore, existing technologies lack effective heat dissipation structures to address the heat generated by the battery during charging. As a result, a large amount of heat accumulates at the battery and charging interface, accelerating battery cell aging, significantly shortening battery life, and further impacting the continuity of logistics operations and equipment operating costs.

[0007] The aforementioned technical problems severely restrict the application efficiency of existing charging and management methods in logistics scenarios. There is an urgent need to innovate and develop a multi-station dedicated charging base and battery housing adaptation structure from the structural design level to solve these problems. Utility Model Content

[0008] The technical objective of this utility model is to propose a multi-station dedicated charging base and battery housing adaptation structure, filling the gap in the existing technology where dedicated rechargeable batteries lack multi-station charging bases. At the same time, it solves the problems of docking deviation and easy disconnection caused by the lack of precise guidance and locking structure between the battery and the charging carrier in independent charging scenarios, and realizes stable charging of multiple batteries.

[0009] The technical solution adopted by this utility model to solve its technical problem is:

[0010] A housing adaptation structure for a multi-station dedicated charging dock and a battery, characterized in that it includes: a multi-station charging dock housing and a matching battery housing;

[0011] The multi-station charging base housing includes: a fixed base fixed to the wall and several charging base housings fixed in parallel to the vertical surface of the fixed base;

[0012] The contact surfaces of the charging base housing and the battery housing are respectively provided with a first guide structure and a second guide structure that cooperate with each other. The battery housing is mounted on the charging base housing through the first guide structure and the second guide structure that cooperate with each other.

[0013] The first guide structure includes: two vertically arranged first guide plates perpendicular to their contact surfaces; the inner sides of the first guide plates are respectively provided with guide protrusions running from top to bottom along their edges;

[0014] The second guide structure includes: two vertically arranged second guide plates perpendicular to their contact surface; the outer surfaces of the second guide plates are respectively provided with guide grooves symmetrically arranged from bottom to top along their edges, the bottom end of the guide grooves being open and the top end being closed;

[0015] The distance between the two first guide plates is greater than the distance between the two second guide plates, and just enough to allow the two guide protrusions to be inserted into the two guide grooves respectively;

[0016] A male charging connector module housing is provided between the bottom ends of the two first guide plates; a female charging connector module housing is provided between the top ends of the two second guide plates.

[0017] Further optimizing the technical solution, the width of the first guide plate gradually narrows from top to bottom, thereby making its outer edge beveled.

[0018] In a further optimized technical solution, the width of the groove opening at the bottom end of the guide groove is greater than the width of the main body of the groove, and the two transition smoothly.

[0019] A further optimized technical solution is provided whereby the male charging connector module housing has pins and the female charging connector module housing has holes corresponding to the pins.

[0020] To further optimize the technical solution, the charging base housing is provided with several heat dissipation slots on both sides.

[0021] A further optimized technical solution is that the interior of the charging base housing is hollow, and the bottom surface has a pre-drilled cable routing hole.

[0023] In a further optimized technical solution, the fixed base is provided with several charging base mounting slots, and the charging base mounting slots are provided with L-shaped upper loading plates and lower loading plates corresponding to each other. The charging base housing is placed between the two, and the upper loading plate is provided with two horizontally parallel mounting holes.

[0025] A further optimized technical solution is that the bottom surface of the fixed base is provided with a wire harness outlet.

[0026] The beneficial effects of this utility model are:

[0027] 1. Achieve integrated multi-station charging management: Through the structural design of a fixed base and parallel charging socket housing, a standardized multi-station housing installation architecture is constructed, filling the gap in existing technologies that lack dedicated multi-station charging sockets. This eliminates the need for multiple independent charging carriers, significantly improving the space utilization of the charging area, while providing a structural foundation for centralized management of multiple battery charging states and reducing the clutter of the working environment.

[0028] 2. Improved accuracy and stability of housing alignment: The charging base housing and battery housing are respectively equipped with a first guiding structure (guide protrusion) and a second guiding structure (guide groove) that cooperate with each other. Through the precise engagement of the protrusion and groove, the problem of lateral displacement during battery insertion in traditional structures is effectively solved, achieving precise alignment of the housings. At the same time, the combination of the guiding structure and the mounting method forms an effective limit, preventing the battery housing from falling off due to external forces such as vibration or contact, ensuring continuous stability during the charging process.

[0029] 3. Optimize heat dissipation performance and equipment safety: The heat dissipation slots on both sides of the charging base housing, together with the hollow structure inside the housing, form a targeted heat dissipation channel, which effectively improves the problem of heat accumulation inside the housing and at the contact interface during charging, slows down the aging of the housing, and improves the safety of the charging process and the service life of the equipment.

[0030] 4. Enhanced structural installation flexibility and practicality: The fixed base achieves wall mounting via fixing ears and holes, while the charging base housing is quickly attached to the fixed base using the gourd holes and hardware hanging plates, making installation and disassembly convenient. The pre-drilled cable routing holes and wiring harness exit design on the bottom facilitates internal wiring organization, further improving the structure's applicability in actual logistics operation scenarios.

[0031] 5. Enhanced reliability of charging interface connection: The male charging connector module housing and the female charging connector module housing are integrated into corresponding positions of the guide structure. With the precise guiding effect of the guide protrusions and grooves, the pins and sockets are ensured to connect synchronously and accurately during the housing connection process, reducing poor contact problems and improving the reliability of the charging connection.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] like Figures 1 to 5As shown, a multi-station dedicated charging dock and battery housing adaptation structure includes a multi-station charging dock housing 1 and a matching battery housing 2. The multi-station charging dock housing 1 serves as the main structure of the charging carrier, enabling simultaneous mounting and charging of multiple batteries. The battery housing 2 is the external protective structure for the batteries to be charged. The two achieve stable connection and charging functionality through a precise housing adaptation design.

[0040] The multi-station charging base housing 1 includes a fixed base 11 fixed to the wall and four charging base housings 12 fixed side by side to the vertical surface of the fixed base 11. The fixed base 11 is made of stainless steel and is integrally formed into a rectangular plate structure. It has symmetrical fixing ears 111 with fixing holes 1111 on both sides. The fixed base 11 can be firmly installed on the wall or the side of the workbench by passing expansion screws through the fixing holes 1111, which meets the installation requirements of logistics operation scenarios. A wire harness outlet 112 is opened in the middle of the bottom surface of the fixed base 11 to centrally lead out the internal wires and avoid the wires being exposed and messy.

[0041] The vertical surface of the fixed base 11 has four evenly spaced charging base mounting slots 113. Each charging base mounting slot 113 has an L-shaped upper plate 1131 and a lower plate 1132 corresponding to each other. The upper plate 1131 extends horizontally into the charging base mounting slot 113, and has two horizontally parallel mounting holes 1133 on its vertical surface. The mounting holes 1133 are used to fix the hardware hanging piece that mates with the hoist hole 122. The end of the hardware hanging piece is curved upward to form a hook structure. The lower plate 1132 is arranged parallel to the upper plate 1131, and has a wire avoidance opening 1134 in the middle to avoid the wiring connection structure at the bottom of the charging base housing 12.

[0042] The charging base housing 12 is also made of ABS engineering plastic and has a rectangular structure. The interior is hollow to accommodate the charging control circuitry, and a circular wiring hole 121 is pre-drilled on the bottom surface. The wiring can be connected to the internal wiring of the fixed base 11 through the wiring hole 121. Two gourd-shaped holes 122 are arranged side-by-side on the contact surface between the charging base housing 12 and the fixed base 11. The larger diameter of the gourd-shaped hole 122 is larger than the diameter of the hook on the hardware hanger, while the smaller diameter is slightly smaller than the hook diameter. During installation, align the larger diameter of the gourd-shaped hole 122 with the hardware hanger, lower it, and then slide it down so that the hook engages with the smaller diameter, thus quickly fixing the charging base housing 12 to the fixed base 11. Combined with the support of the download plate 1132, this ensures the charging base housing 12 is stably installed.

[0043] The charging base housing 12 has a first guide structure on its contact surface facing the battery housing 2, and the battery housing 2 has a second guide structure on its corresponding contact surface that cooperates with the first guide structure. The first guide structure includes two vertically arranged first guide plates 13 perpendicular to the contact surface. The first guide plates 13 are integrally formed with the charging base housing 12, and their width gradually narrows from top to bottom, with the outer edge forming a bevel to facilitate the insertion of the battery housing 2. The inner surfaces of the first guide plates 13 are symmetrically provided with guide protrusions 131 running from top to bottom along their edges. The guide protrusions 131 are cuboid protrusions.

[0044] The second guide structure includes two vertically aligned second guide plates 21 perpendicular to the contact surface. The second guide plates 21 are integrally formed with the battery casing 2. Symmetrical guide grooves 211 are provided on their outer surfaces, running from bottom to top along their edges. The bottom end of each guide groove 211 is open, and the top end is closed. The width of the groove opening at the bottom end is greater than the width of the main body of the groove, with a smooth transition between the two via an arc surface. The distance between the two first guide plates 13 is greater than the distance between the two second guide plates 21, allowing the two guide protrusions 131 to be inserted into the two guide grooves 211 respectively. Precise guidance is achieved through the interlocking of the protrusions and grooves.

[0045] A male charging connector module housing 14 is located between the bottom ends of the two first guide plates 13, and the male charging connector module housing 14 has three metal pins 141. Correspondingly, a female charging connector module housing 22 is located between the top ends of the two second guide plates 21, and the female charging connector module housing 22 has sockets 221 that correspond one-to-one with the pins 141. When the guide protrusion 131 is fully inserted into the guide groove 211, the pins 141 are precisely inserted into the sockets 221, thus achieving circuit connection.

[0046] To improve heat dissipation performance, five evenly spaced heat dissipation slots 123 are provided on each of the two sides of the charging base housing 12. The heat dissipation slots 123 extend vertically and communicate with the internal cavity of the charging base housing 12, which can quickly dissipate the heat generated during the charging process.

[0047] In practical use, the fixing base 11 is first installed in the designated position using the fixing ears 111. Then, the three charging base housings 12 are fixed to the fixing base 11 through the gourd holes 122 and the hardware hanging pieces, completing the assembly of the multi-station charging base. During charging, the operator holds the battery housing 2, aligns the second guide plate 21 with the first guide plate 13, aligns the bottom opening of the guide groove 211 with the top of the guide protrusion 131, and then slides the battery housing 2 vertically downwards. The guide protrusion 131 gradually embeds into the guide groove 211 until the battery housing 2 is mounted on the charging base housing 12. At this time, the pin 141 and the socket 221 are precisely aligned, achieving stable charging. The heat generated during charging is dissipated through the heat dissipation slots 123, ensuring charging safety. When the battery needs to be removed, the guide structure can be separated by lifting the battery housing 2 upwards, making the operation convenient and efficient.
