[0028] This utility model provides a battery housing 100.

[0029] Please refer to Figures 1 to 4, in an embodiment of the present utility model, the battery housing 100 is applied to a single-row battery pack. The battery housing 100 includes: a first arc-shaped member 1 and a second arc-shaped member 2. The first arc-shaped member 1 and the second arc-shaped member 2 are correspondingly arranged. The first arc-shaped member 1 and the second arc-shaped member 2 are connected and enclose to form an arc-shaped groove 1a for accommodating and limiting the battery. One end of the first arc-shaped member 1 away from the second arc-shaped member 2 is provided with a limiting platform 11. The limiting platform 11 covers part of the notch and is used to prevent the single-row battery pack in the arc-shaped groove 1a from sliding out of the arc-shaped groove 1a; and / or, one end of the second arc-shaped member 2 away from the first arc-shaped member 1 is provided with a limiting platform 11. The limiting platform 11 covers part of the notch and is used to prevent the single-row battery pack in the arc-shaped groove 1a from sliding out of the arc-shaped groove 1a. A plurality of shock-absorbing grooves 11b are formed on the limiting platform 11, and each shock-absorbing groove 11b is arranged at intervals.

[0030] In an embodiment, the first arc-shaped member 1 and the second arc-shaped member 2 are components of the battery housing 100. The first arc-shaped member 1 and the second arc-shaped member 2 are generally arc-shaped shell members with channels for installing battery units inside. The materials of the two are generally insulating and flame-retardant plastic materials, such as plastic alloy materials of polyvinyl chloride (PVC), polyethylene (PE), or ABS (acrylonitrile-butadiene-styrene copolymer) and PC (polycarbonate). Such materials can achieve the effects of flame retardancy and preventing short circuits of the single-row battery pack while fixing the single-row battery pack. The first arc-shaped member 1 and the second arc-shaped member 2 are detachably connected by bolts or buckles, etc. After the first arc-shaped member 1 and the second arc-shaped member 2 are connected, they enclose to form an arc-shaped groove 1a for installing the single-row battery pack. The single-row battery pack is inserted and limited in the arc-shaped groove 1a to further fix and protect the battery pack.

[0031] Furthermore, in order to ensure the stable positioning of the battery pack in the battery housing 100 and reduce its movement during collision or extrusion, a limiting platform 11 is provided at one end of the first arc-shaped member 1 away from the second arc-shaped member 2. This limiting platform 11 directly abuts against one end of the single-row battery pack, thus providing a stable support point. Similarly, a limiting platform 11 can also be provided at one end of the second arc-shaped member 2 away from the first arc-shaped member 1. This limiting platform 11 also abuts against the corresponding end of the single-row battery pack to provide additional stability. Such a design helps to disperse and absorb external impact forces, reduce battery deformation or failure caused by collision or extrusion, and thus improve the durability and reliability of the entire surveying and detecting device.

[0032] It should be noted that in order to further enhance the protection effect of the battery housing 100 on the single-row battery pack, especially when it is subjected to external impacts and vibrations, a plurality of shock-absorbing grooves 11b are designed on the limiting platform 11. These shock-absorbing grooves 11b are evenly spaced along the length direction of the limiting platform 11, forming a series of buffer spaces. Each shock-absorbing groove 11b is independently opened, and there is a certain distance between them to ensure that when the battery housing 100 is collided or squeezed, the impact force can be absorbed and dispersed through the elastic deformation of the shock-absorbing grooves 11b, reducing the force directly transmitted to the battery pack. This spaced arrangement of the shock-absorbing grooves 11b not only improves the impact resistance of the battery housing 100, but also helps to reduce the wear caused by vibration during the normal use of the battery pack, thereby extending the service life of the battery pack and ensuring a stable and reliable power supply for the surveying and mapping detection equipment in a complex and changeable working environment. Through the structure of the limiting platform 11 designed in this way, the battery housing 100 can provide more comprehensive and effective protection for the single-row battery pack.

[0033] The technical solution of the present utility model is to design a battery housing 100. This battery housing 100 is applied to a single-row battery pack. The battery housing 100 includes a first arc-shaped member 1 and a second arc-shaped member 2. The first arc-shaped member 1 and the second arc-shaped member 2 are correspondingly arranged and detachably connected through structures such as bolts or buckles. The arc-shaped groove 1a formed by enclosing the first arc-shaped member 1 and the second arc-shaped member 2. The design of the arc-shaped structure can be adapted to the existing surveying and mapping detection equipment, ensuring that the single-row battery pack is firmly positioned within the battery housing 100, reducing movement during collision or extrusion, helping to disperse and absorb external impact forces, and reducing battery deformation or failure caused by collision or extrusion. By enhancing the stability and durability of the single-row battery pack, this design helps to protect the entire surveying and mapping detection equipment and avoid equipment failures or performance degradation caused by battery pack damage.

[0034] In an embodiment of the present utility model, please refer to Figure 1 and Figure 3 , a series connection groove 11a is opened on the limiting platform 11; the series connection groove 11a extends along the arrangement direction of the single-row battery pack.

[0035] In this embodiment, the design of the limiting platform 11 of the battery housing 100 is further optimized to adapt to the series connection between the unit batteries of a single-row battery pack. The limiting platform 11 is located at one end of the first arc-shaped member 1 or the second arc-shaped member 2 and abuts against the corresponding end of the single-row battery pack. To facilitate the series connection of the battery pack, one or more series slots 11a are specifically provided on the limiting platform 11. These series slots 11a extend along the arrangement direction of the single-row battery pack, that is, they are consistent with the linear layout of the battery pack. The design of the series slots 11a allows the individual batteries in the battery pack to be connected to each other through electrical connectors (such as wires, terminals, etc.) to achieve continuous current transmission. Such a layout not only facilitates the series configuration of the battery pack, but also helps in the maintenance and replacement of the batteries. At the same time, it ensures the neatness and order inside the battery housing 100. In this way, the battery housing 100 not only provides physical protection, but also promotes the electrical integration of the battery pack, enhancing the overall functionality and practicality.

[0036] In an embodiment of the present utility model, please refer to Figure 3 , a clearance slot 11c is provided at one end of the limiting platform 11 close to the series slot 11a, and the clearance slot 11c is located at the notch of the arc-shaped groove 1a.

[0037] In this embodiment, the design of each limiting platform 11 of the battery housing 100 includes a clearance slot 11c, which is located at the notch of the arc-shaped groove 1a and is adjacent to the series slot 11a. The main function of the clearance slot 11c is to provide space for the connection point between the wire of the series-connected battery unit and the battery unit to avoid interference between the wire and the battery housing 100. Specifically, the size and shape of the clearance slot 11c are designed to accommodate the contour of the wire connection point, ensuring that during the installation and operation of the battery pack, the wire can be freely connected to the battery unit without being hindered by the housing. Such a design not only optimizes the installation process of the battery pack, but also reduces the risk of short circuit or wear that may be caused by the contact between the wire and the housing, thereby improving the overall reliability and safety of the battery pack.

[0038] In an embodiment of the present utility model, please refer to Figure 3 , the arc-shaped groove 1a includes a battery slot 2a and a communication slot 1c. The communication slot 1c is located between two adjacent battery slots 2a to communicate the adjacent battery slots 2a.

[0039] In one embodiment, the arc-shaped groove 1a of the battery housing 100 is designed with heat management issues generated by the single-row battery pack during long-term operation in mind. To improve the heat dissipation efficiency, the arc-shaped groove 1a includes a battery groove 2a and a communication groove 1c. The arc-shaped groove 1a cleverly forms the communication groove 1c between the individual battery cells of the single-row battery pack. These communication grooves 1c are opened along the battery grooves 2a, and they can be linear or of any shape that matches the arrangement of the battery cells to maximize the heat dissipation area. The design of the communication groove 1c allows air or other cooling media to flow between the battery cells, thereby effectively removing the heat generated by the battery during charging and discharging. This direct heat dissipation channel design not only improves the heat conduction efficiency but also helps to keep the battery pack operating within the optimal working temperature range, avoiding affecting the battery performance or shortening the battery life due to overheating. Through this innovative design of the communication groove 1c, the battery housing 100 not only provides physical protection but also enhances the thermal management ability of the battery pack, ensuring the stability and reliability of the mapping detection device during continuous operation.

[0040] In one embodiment of the present utility model, please refer to Figure 4 , a plurality of alternately arranged connecting bosses 13 and connecting grooves 13a are formed on the outer wall of the first arc-shaped member 1. Each two connecting bosses 13 enclose to form a battery groove 2a, and each two connecting grooves 13a enclose to form a communication groove 1c; or, a plurality of alternately arranged connecting bosses 13 and connecting grooves 13a are formed on the outer wall of the second arc-shaped member 2. Each two connecting bosses 13 enclose to form a battery groove 2a, and each two connecting grooves 13a enclose to form a communication groove 1c.

[0041] In one embodiment of the present utility model, a plurality of alternately arranged connecting bosses 13 and connecting grooves 13a are formed on the outer walls of the first arc-shaped member 1 and the second arc-shaped member 2 of the battery housing 100, realizing the construction of the battery groove 2a and the communication groove 1c. Specifically, the gap formed between every two adjacent connecting bosses 13 constitutes the battery groove 2a for accommodating a single battery cell in the single-row battery pack; the gap formed between every two adjacent connecting grooves 13a constitutes the communication groove 1c for providing a communication space between adjacent battery grooves 2a. This design allows the battery grooves 2a and the communication grooves 1c to be continuously arranged along the arc-shaped members of the battery housing 100, forming an effective structure that can not only fix the battery cells but also promote the heat dissipation inside the battery pack. Through this structural design, the battery housing 100 not only provides a stable physical support but also optimizes the thermal management, ensuring the performance and life of the battery pack under various working conditions.

[0042] In one embodiment of the present utility model, please refer to Figure 4 , a temperature monitoring hole 1b is opened on the first arc-shaped member 1; and / or, a temperature monitoring hole 1b is opened on the second arc-shaped member 2.

[0043] In one embodiment, in order to ensure temperature monitoring and safety management during the operation of the single-row battery pack, temperature monitoring holes 1b are specially designed on the first arc-shaped member 1 and / or the second arc-shaped member 2 of the battery housing 100. These monitoring holes are located at specific positions on the arc-shaped members and are precisely formed to facilitate the insertion and fixation of temperature sensors. The arrangement of the temperature monitoring holes 1b allows the temperature sensors to directly contact the surface or the vicinity of the battery pack, thereby enabling real-time monitoring of the temperature changes of the battery during charging and discharging. Through these monitoring holes, the temperature data of the battery pack can be effectively obtained and transmitted to the control system or the alarm device, so as to take timely measures when the battery temperature abnormally rises and prevent safety accidents caused by overheating. This design not only improves the safety of the battery pack but also helps to optimize the working efficiency of the battery and extend its service life. By respectively forming the temperature monitoring holes 1b on the two arc-shaped members of the battery housing 100, we can achieve comprehensive monitoring of the battery pack temperature and ensure the reliability and stability of the mapping and detection equipment under various working conditions.

[0044] In one embodiment of the present utility model, please refer to Figure 3 , a plurality of reinforcing ribs 12 are formed on the first arc-shaped member 1; and / or, a plurality of reinforcing ribs 12 are formed on the second arc-shaped member 2; each of the reinforcing ribs 12 is arranged at intervals.

[0045] In a specific embodiment of the present utility model, in order to enhance the structural stability and impact resistance of the battery housing 100, a plurality of reinforcing ribs 12 are designed on the first arc-shaped member 1 and / or the second arc-shaped member 2. These reinforcing ribs 12 are evenly distributed on the inner or outer surface of the arc-shaped member. They are protruding structures that can significantly improve the rigidity and strength of the arc-shaped member without adding too much weight. Each of the reinforcing ribs 12 is arranged at intervals to ensure uniform mechanical reinforcement throughout the arc-shaped member and avoid local stress concentration. The design of the reinforcing ribs 12 can be linear, arc-shaped or other suitable shapes to adapt to the geometric structure and stress characteristics of the battery housing 100. Through the reinforcing ribs 12 arranged at intervals, the battery housing 100 can better withstand external impacts and squeezes, protect the internal single-row battery pack from damage, and thus improve the durability and reliability of the entire mapping and detection equipment. This optimization of the structure enables the battery housing 100 to have excellent protection performance while remaining lightweight.

[0046] In one embodiment of the present utility model, please refer to Figure 4 , a weight-reducing groove 1d is formed on the first arc-shaped member 1; and / or, a weight-reducing groove 1d is formed on the second arc-shaped member 2.

[0047] In a specific embodiment of the present utility model, in order to reduce the overall weight of the battery housing 100 without sacrificing structural strength, weight-reducing grooves 1d are designed on the first arc-shaped member 1 and / or the second arc-shaped member 2. These weight-reducing grooves 1d are grooves opened at appropriate positions on the arc-shaped member, and they can be linear, curved, or any other shape that helps reduce the amount of material used without reducing structural integrity. The setting of the weight-reducing grooves 1d is carefully calculated to ensure that while a certain amount of material is removed, the arc-shaped member can still maintain sufficient strength and rigidity to support and protect the internal single-row battery pack 200. Through this design, the weight of the battery housing 100 is reduced, which helps to reduce the burden on the entire mapping and detection device and improve its portability and operation flexibility. At the same time, the reasonable layout of the weight-reducing grooves 1d also helps to achieve the aesthetics and functionality of the battery housing 100, making it have a good appearance design while meeting the structural requirements.

[0048] In an embodiment of the present utility model, please refer to Figure 1 , both the first arc-shaped member 1 and the second arc-shaped member 2 are made of plastic alloy material.

[0049] In a specific embodiment of the present utility model, in order to ensure the durability and comprehensive performance of the battery housing 100, both the first arc-shaped member 1 and the second arc-shaped member 2 are made of a plastic alloy material of ABS and PC. This material is a mixture of ABS (acrylonitrile-butadiene-styrene copolymer) and PC (polycarbonate), which combines the advantages of the two materials, namely the easy processing and cost-effectiveness of ABS, and the high heat resistance and impact strength of PC. By using the ABS and PC materials, the battery housing 100 is lightweight and economical while also having excellent mechanical properties and chemical resistance, and can effectively protect the internal single-row battery pack from external impacts and environmental factors. In addition, the battery housing 100 made of ABS and PC materials also has good electrical insulation properties and is suitable for use in devices that require electromagnetic compatibility. The selection of this material not only improves the performance of the battery housing 100 but also meets the strict requirements of modern electronic devices for the comprehensive performance of materials.

[0050] The present utility model also proposes a single-row battery pack, which includes a battery housing 100 and a plurality of battery cells. The specific structure of the battery housing 100 refers to the above embodiments. Since this single-row battery pack adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the plurality of battery cells are connected in series; each battery cell is inserted and limited in the arc-shaped groove 1a.

[0051] In this embodiment, the single-row battery pack includes a battery housing 100, and an arc-shaped groove 1a for accommodating and positioning battery cells is provided inside the housing. The battery pack is composed of multiple battery cells, and these battery cells are connected in series to provide the required voltage and capacity. Each battery cell is precisely snap-fitted and positioned in the arc-shaped groove 1a inside the battery housing 100, ensuring that the battery cell is firmly positioned inside the battery housing 100 and preventing displacement when subjected to impact or vibration. The design of the arc-shaped groove 1a allows the battery cells to be evenly distributed along the channel, optimizing space utilization while providing sufficient support and protection. This design not only improves the structural stability of the battery pack but also facilitates the heat dissipation and maintenance of the battery cells, ensuring the performance and safety of the battery pack under various working conditions. Through this design of the single-row battery pack, effective series connection of the battery cells can be achieved while maintaining the compactness and reliability of the battery pack, which is suitable for application scenarios that require high energy density and stable performance.
