Description

Technical Field

[0001] This disclosure relates to the technical field of battery structures for unmanned delivery vehicles, and in particular to a battery structure for unmanned delivery vehicles. Background Technology

[0002] Currently, the last mile (or "last kilometer") of express delivery mainly relies on manual operations by delivery personnel. This delivery method has the following drawbacks: First, it requires a large number of delivery personnel, leading to a significant increase in labor costs; second, in order to improve work efficiency, delivery personnel often need to ride two-wheeled or three-wheeled motorcycles, which not only increases traffic congestion but also poses safety hazards to the delivery personnel themselves, lacking safety; at the same time, it is difficult to guarantee the security of user information when using delivery personnel for manual delivery, and the lack of flexibility in delivery time affects delivery efficiency.

[0003] To address these issues, some manufacturers have conducted further research and development. For example, existing technology patent CN107856763B proposes an intelligent unmanned express delivery vehicle that can achieve fast, efficient, and safe express delivery, thereby not only effectively improving the efficiency of express delivery but also significantly reducing labor costs.

[0004] However, when the aforementioned intelligent unmanned delivery vehicle makes deliveries in the rain, if rainwater enters the battery compartment and directly contacts the electrical connection between the battery pack and the battery compartment, the battery pack is highly susceptible to short circuits or even explosions due to direct contact with external water or other conductive liquids. This not only significantly reduces the battery pack's lifespan and safety but also prevents the intelligent unmanned delivery vehicle from making deliveries in rainy weather, greatly reducing its applicability and delivery efficiency. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a battery structure for unmanned delivery vehicles that not only has a long service life and safety, but also improves the applicability and delivery efficiency of unmanned delivery vehicles.

[0006] The purpose of this disclosure is achieved through the following technical solution: A battery structure for an unmanned delivery vehicle, for installation in the battery compartment of the unmanned delivery vehicle, the battery structure for the unmanned delivery vehicle including a waterproof shell and a battery cell assembly; The waterproof housing has a sealed limiting cavity, and the battery cell assembly is installed and limited within the sealed limiting cavity; The outer peripheral wall of the waterproof housing also forms a connection port that communicates with the sealing and limiting cavity. The conductive terminal of the battery cell assembly passes through the connection port and protrudes from the outer peripheral wall of the waterproof housing. An annular limiting part is fixed on the outer peripheral wall of the waterproof housing. The annular limiting part and the waterproof housing together form a plug groove. The annular limiting part surrounds the conductive terminal. The conductive terminal is disposed in the plug groove. The plug groove is used to be adapted to the plug of the battery compartment. The conductive terminal is used to be electrically connected to the conductive end of the plug. An elastic sealing ring is provided at the bottom of the plug groove. The elastic sealing ring surrounds the conductive terminal. The elastic sealing ring is used to be opposite to the end of the plug. The two sides of the elastic sealing ring are used to press against the end of the plug and the bottom wall of the plug groove when the plug is inserted into the plug groove.

[0007] In one embodiment, the bottom of the insertion slot is further provided with an annular limiting groove, which surrounds the conductive terminal and is used to accommodate and limit the elastic sealing ring. The outer wall of the elastic sealing ring is in interference fit with the inner wall of the annular limiting groove, and the annular limiting groove is positioned opposite to the end of the insertion connector.

[0008] In one embodiment, a first waterproof sealant block is filled between the outer wall of the elastic sealing ring and the inner wall of the annular limiting groove.

[0009] In one embodiment, the waterproof housing is further formed with a guide limiting groove that extends to one side of the waterproof housing formed in the insertion groove. The guide limiting groove is used to be adapted to and opposite to the guide flange of the inner peripheral wall of the battery compartment.

[0010] In one embodiment, the annular limiting portion has a guide limiting flange protruding on one side of the insertion groove, and the guide limiting flange is used to fit with the guide limiting groove on the outer peripheral wall of the insertion connector.

[0011] In one embodiment, a guide bevel is formed at one end of the guide limiting flange adjacent to the opening of the insertion slot.

[0012] In one embodiment, there are multiple guide limiting flanges, which are spaced apart along the inner peripheral wall of the insertion groove.

[0013] In one embodiment, there is an angle between the guide ramp and the inner peripheral wall of the insertion slot, and the angle is 30°-60°.

[0014] In one embodiment, the outer wall of the guide limiting flange is provided with a friction buffer layer.

[0015] In one embodiment, the waterproof housing includes an upper shell and a lower cover. The upper shell forms a limiting groove and a connection port communicating with the limiting groove. The limiting groove is used to accommodate and limit the battery cell assembly. The lower cover is disposed at the opening of the limiting groove, and the outer periphery of the upper shell and the outer periphery of the lower cover are sealed together to form the sealed limiting cavity.

[0016] In one embodiment, the bottom of the insertion slot is further provided with an annular support flange, the annular support flange surrounds the conductive terminal, and the inner peripheral wall of the annular support flange abuts against and supports the outer peripheral wall of the conductive terminal.

[0017] In one embodiment, the gap between the outer periphery of the upper shell and the outer periphery of the lower cover is filled with a second waterproof sealant block.

[0018] Compared with the prior art, this disclosure has at least the following advantages: 1. The aforementioned battery structure for unmanned delivery vehicles, with its waterproof casing forming a sealed limiting cavity, allows the battery cell assembly to be securely positioned and sealed within the cavity. This prevents water or other conductive liquids from entering the sealed limiting cavity during rainy weather, effectively avoiding short circuits caused by direct contact. This allows the unmanned delivery vehicle to continue delivery even in rainy conditions, significantly improving its applicability and delivery efficiency. Furthermore, the waterproof casing effectively protects the battery cell assembly from damage or short circuits caused by direct impact or vibration against the inner wall of the battery compartment. This significantly enhances the lifespan and safety of the battery structure used in unmanned delivery vehicles.

[0019] 2. Since the outer peripheral wall of the waterproof housing also forms a connection port communicating with the sealing and limiting cavity, the conductive terminals of the battery cell assembly pass through the connection port and protrude from the outer peripheral wall of the waterproof housing. An annular limiting part is fixed to the outer peripheral wall of the waterproof housing. The annular limiting part and the waterproof housing together form a insertion groove. The annular limiting part surrounds the conductive terminal, which is located within the insertion groove. The insertion groove is adapted to the connector of the battery compartment so that the connector can be reliably inserted into the groove. The conductive terminal is used for electrical connection with the conductive end of the connector. An elastic sealing ring is provided at the bottom of the insertion groove, surrounding the conductive terminal. The elastic sealing ring is positioned opposite to the end of the connector. The two sides of the elastic sealing ring are used to press against the end of the connector and the bottom wall of the insertion groove when the connector is inserted into the groove, so that when the connector is inserted into the groove, the elastic sealing ring can... The gap between the end and the bottom wall of the connector slot is filled and sealed. This allows the unmanned delivery vehicle to deliver packages even in rainy weather. The elastic sealing ring effectively prevents external water or other conductive liquids from directly contacting the conductive terminals through the gap between the connector and the bottom wall of the connector slot. This avoids short circuits caused by direct contact between the battery cell components and external water or other conductive liquids, enabling the unmanned delivery vehicle to deliver packages even in rainy weather. This greatly improves the applicability and delivery efficiency of the unmanned delivery vehicle. At the same time, the elastic sealing ring can also buffer and disperse the insertion force between the connector and the conductive terminals through its own elasticity, preventing damage or even destruction of the conductive terminals due to excessive insertion force. This greatly improves the service life and safety of the battery structure used in the unmanned delivery vehicle. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Compared with the prior art, this disclosure has at least the following advantages: like Figures 1 to 8As shown, a battery structure 10 for an unmanned delivery vehicle is installed in the battery compartment of the unmanned delivery vehicle. The battery structure 10 includes a waterproof housing 100 and a battery cell assembly 200. The waterproof housing 100 forms a sealing and limiting cavity 110, and the battery cell assembly 200 is installed and limited within the sealing and limiting cavity 110, so that the waterproof housing 100 can reliably limit and seal the battery cell assembly 200 within the sealing and limiting cavity 110. This prevents water or other conductive liquids from entering the sealing and limiting cavity 110 when the unmanned delivery vehicle is making deliveries in rainy weather. This effectively prevents short circuits caused by direct contact between the battery cell assembly 200 and external water or other conductive liquids, enabling the unmanned delivery vehicle to deliver packages even in rainy weather, thus greatly improving its applicability and delivery efficiency. Simultaneously, the waterproof casing 100 effectively protects the battery cell assembly 200, preventing damage or short circuits caused by direct collisions or vibrations with the inner wall of the battery compartment when the unmanned delivery vehicle is subjected to external factors such as impacts or vibrations. This significantly improves the lifespan and safety of the battery structure 10 used in the unmanned delivery vehicle.

[0026] like Figures 1 to 8As shown, further, the outer peripheral wall of the waterproof housing 100 also forms a connection port 120 communicating with the sealing and limiting cavity 110. The conductive terminal 210 of the battery cell assembly 200 passes through the connection port 120 and protrudes from the outer peripheral wall of the waterproof housing 100. An annular limiting part 130 is fixed to the outer peripheral wall of the waterproof housing 100. The annular limiting part 130 and the waterproof housing 100 together form a insertion groove 140. The annular limiting part 130 surrounds the conductive terminal 210. The conductive terminal 210 is disposed in the insertion groove 140 and inserted. The slot 140 is adapted to fit the connector of the battery compartment so that the connector can be securely inserted into the slot 140; the conductive terminal 210 is used for electrical connection with the conductive end of the connector; the bottom of the slot 140 is provided with an elastic sealing ring 150, which surrounds the conductive terminal 210 and is positioned opposite to the end of the connector; the two sides of the elastic sealing ring 150 are used to press against the end of the connector and the bottom wall of the slot 140 when the connector is inserted into the slot 140. When the connector is inserted into the connector slot 140, the elastic sealing ring 150 can fill and seal the gap between the connector end and the bottom wall of the connector slot 140. This allows the unmanned delivery vehicle to effectively prevent external water or other conductive liquids from directly contacting the conductive terminal 210 through the gap between the connector and the bottom wall of the connector slot 140 during delivery in rainy weather. This avoids short circuits caused by direct contact between the battery cell assembly 200 and external water or other conductive liquids, enabling the unmanned delivery vehicle to perform delivery even in rainy weather, thus greatly improving the applicability and delivery efficiency of the unmanned delivery vehicle. At the same time, the elastic sealing ring 150 can also buffer and disperse the insertion force between the connector and the conductive terminal 210 through its own elasticity, preventing damage or even destruction of the conductive terminal 210 due to excessive insertion force. This greatly improves the service life and safety of the battery structure 10 used in the unmanned delivery vehicle.

[0027] The aforementioned battery structure 10 for unmanned delivery vehicles, with a waterproof housing 100 forming a sealed limiting cavity 110, allows the battery cell assembly 200 to be installed and limited within the sealed limiting cavity 110. This ensures that the waterproof housing 100 reliably limits and seals the battery cell assembly 200 within the sealed limiting cavity 110. When the unmanned delivery vehicle is used for delivery in rainy weather, the waterproof housing 100 prevents water or other conductive liquids from entering the sealed limiting cavity 110, effectively avoiding direct contact between the battery cell assembly 200 and external water or other conductive liquids. The contact can cause a short circuit, which allows the unmanned delivery vehicle to deliver packages even in rainy weather, thus greatly improving its applicability and delivery efficiency. At the same time, the waterproof shell 100 can effectively protect the battery cell assembly 200, preventing damage or even short circuits caused by direct collision or compression between the battery cell assembly 200 and the inner wall of the battery compartment when the unmanned delivery vehicle is affected by external factors such as collision or vibration. This greatly improves the service life and safety of the battery structure 10 used in the unmanned delivery vehicle.

[0028] Furthermore, since the outer peripheral wall of the waterproof housing 100 also forms a connection port 120 that communicates with the sealing and limiting cavity 110, the conductive terminal 210 of the battery cell assembly 200 passes through the connection port 120 and protrudes from the outer peripheral wall of the waterproof housing 100. An annular limiting portion 130 is fixed to the outer peripheral wall of the waterproof housing 100. The annular limiting portion 130 and the waterproof housing 100 together form a insertion groove 140. The annular limiting portion 130 surrounds the conductive terminal 210, and the conductive terminal 210 is disposed within the insertion groove 140. 0 is used to adapt to the connector of the battery compartment so that the connector can be reliably inserted into the connector slot 140; the conductive terminal 210 is used to electrically connect to the conductive end of the connector; the bottom of the connector slot 140 is provided with an elastic sealing ring 150, the elastic sealing ring 150 surrounds the conductive terminal 210, the elastic sealing ring 150 is used to be opposite to the end of the connector, and the two sides of the elastic sealing ring 150 are used to press against the end of the connector and the bottom wall of the connector slot 140 when the connector is inserted into the connector slot 140, so that... When the connector is inserted into the connector slot 140, the elastic sealing ring 150 fills and seals the gap between the connector end and the bottom wall of the connector slot 140. This effectively prevents external water or other conductive liquids from directly contacting the conductive terminal 210 through the gap between the connector and the bottom wall of the connector slot 140 when the unmanned delivery vehicle is making deliveries in rainy weather. This avoids short circuits caused by direct contact between the battery cell assembly 200 and external water or other conductive liquids, thus enabling the unmanned delivery vehicle to make deliveries even in rainy weather, thereby greatly improving the applicability and delivery efficiency of the unmanned delivery vehicle. At the same time, the elastic sealing ring 150 can also buffer and disperse the insertion force between the connector and the conductive terminal 210 through its own elasticity, preventing damage or even destruction of the conductive terminal 210 due to excessive insertion force. This greatly improves the service life and safety of the battery structure 10 used in the unmanned delivery vehicle.

[0029] like Figure 2 and Figure 7As shown, in one embodiment, an annular limiting groove 141 is also formed at the bottom of the insertion groove 140. The annular limiting groove 141 surrounds the conductive terminal 210 and is used to accommodate the limiting elastic sealing ring 150. The outer wall of the elastic sealing ring 150 is in interference fit with the inner wall of the annular limiting groove 141. The annular limiting groove 141 is arranged opposite to the end of the insertion connector so that the annular limiting groove 141 can not only reliably limit the elastic sealing ring 150 to the preset position of the insertion groove 140, avoiding the phenomenon of the elastic sealing ring 150 shaking or even displacement when the insertion connector is inserted into the insertion groove 140, but also increase the interference fit area between the elastic sealing ring 150 and the waterproof shell 100, thereby greatly improving the waterproof effect and usage stability of the battery structure 10 used in the unmanned express delivery vehicle.

[0030] like Figure 2 and Figure 7 As shown, in one embodiment, a first waterproof sealant block (not shown) is filled between the outer wall of the elastic sealing ring 150 and the inner wall of the annular limiting groove 141, so that the elastic sealing ring 150 can be more securely fixed in the annular limiting groove 141. At the same time, the waterproof sealant block can further seal the space between the outer wall of the elastic sealing ring 150 and the inner wall of the annular limiting groove 141, thereby further improving the waterproof effect and stability of the battery structure 10 used in the unmanned express delivery vehicle.

[0031] like Figure 2 As shown, in one embodiment, the elastic sealing ring 150 is a waterproof silicone ring, so that the elastic sealing ring 150 can have better sealing performance and elastic cushioning performance.

[0032] like Figure 1 As shown, in one embodiment, the waterproof housing 100 also forms a guide limiting groove 160, which extends to one side of the waterproof housing 100 formed in the insertion groove 140. The guide limiting groove 160 is adapted to and oppositely arranged with the guide flange of the inner peripheral wall of the battery compartment, so that the battery structure 10 for the unmanned express delivery vehicle can be quickly installed in the preset position of the battery compartment by the guide of the guide limiting groove 160. This greatly reduces the installation difficulty of the battery structure 10 for the unmanned express delivery vehicle. At the same time, the battery structure 10 for the unmanned express delivery vehicle can also be reliably limited to the preset position of the battery compartment by the mutual cooperation between the guide limiting groove 160 and the guide flange, thereby greatly improving the ease of use and stability of the battery structure 10 for the unmanned express delivery vehicle.

[0033] like Figures 1 to 2As shown, in one embodiment, the annular limiting portion 130 has a guide limiting flange 131 protruding from one side of the insertion groove 140. The guide limiting flange 131 is adapted to the guide limiting groove on the outer peripheral wall of the plug, so that the plug can be quickly inserted into the preset position of the insertion groove 140 by the guidance of the guide limiting flange 131, ensuring that the conductive end of the plug and the conductive terminal 210 abut against each other and are electrically connected. At the same time, the plug can also be connected to the insertion groove 140 by the guide limiting flange 131. The guide limiting slide grooves cooperate with each other to securely limit the plug in the preset position of the plug groove 140. Moreover, the inner peripheral wall of the plug groove 140 can increase the contact area with the plug by cooperating with the guide limiting flange 131 and the guide limiting slide groove, thereby increasing the friction between the inner peripheral wall of the plug groove 140 and the plug, so that the plug can be more securely limited in the plug groove 140, thereby further improving the ease of use and stability of the battery structure 10 used in unmanned express delivery vehicles.

[0034] like Figures 1 to 2 As shown, in one embodiment, a guide bevel 1311 is formed at one end of the guide limiting flange 131 near the opening of the insertion slot 140, so as to further reduce the difficulty of inserting the connector into the insertion slot 140 and improve the ease of use of the battery structure 10 for unmanned express delivery vehicles.

[0035] like Figures 1 to 3 As shown, in one embodiment, there are multiple guiding and limiting flanges 131. The multiple guiding and limiting flanges 131 are spaced apart along the inner peripheral wall of the insertion groove 140 so that the plug can be more reliably limited in the insertion groove 140, thereby greatly improving the reliability of the electrical connection between the conductive end of the plug and the conductive terminal 210, and thus improving the stability of the battery structure 10 used in the unmanned express delivery vehicle.

[0036] like Figure 5 As shown, in one embodiment, there is an angle between the guide slope 1311 and the inner peripheral wall of the insertion groove 140, and the angle is 30°-60°.

[0037] like Figure 2 As shown, in one embodiment, the outer wall of the guide limiting flange 131 is provided with a friction buffer layer 1312 to increase the friction between the guide limiting flange 131 and the guide limiting groove, so that the connector can be more securely limited in the insertion groove 140. At the same time, when the connector is inserted into the insertion groove 140, the friction buffer layer 1312 can also buffer and disperse the collision force or extrusion force between the guide limiting flange 131 and the guide limiting groove, so as to avoid the guide limiting flange 131 being damaged or even destroyed due to the large collision force or extrusion force, thereby greatly improving the stability of the battery structure 10 used in unmanned express delivery vehicles.

[0038] like Figure 2 As shown, in one embodiment, the friction buffer layer 1312 is a silicone rubber layer, so that the friction buffer layer 1312 can have a high coefficient of friction and buffering performance.

[0039] like Figure 4 As shown, in one embodiment, the waterproof housing 100 includes an upper shell 170 and a lower cover 180. The upper shell 170 forms a limiting groove 171 and a connection port 120 communicating with the limiting groove 171. The limiting groove 171 is used to accommodate the limiting cell assembly 200. The lower cover 180 is disposed on the opening of the limiting groove 171, and the outer periphery of the upper shell 170 and the outer periphery of the lower cover 180 are sealed together to form a sealed limiting cavity 110, so as to prevent external water or other conductive liquids from entering the sealed limiting cavity 110 through the gap between the upper shell 170 and the lower cover 180, effectively avoiding the phenomenon of short circuit caused by direct contact of the cell assembly 200 with external water or other conductive liquids.

[0040] like Figures 1 to 5 As shown, in one embodiment, the bottom of the insertion slot 140 is further provided with an annular support flange 142. The annular support flange 142 surrounds the conductive terminal 210, and the inner peripheral wall of the annular support flange 142 abuts against and supports the outer peripheral wall of the conductive terminal 210. This allows the annular support flange 142 to support and limit the conductive terminal 210 when the connector is inserted into the insertion slot 140, preventing the conductive terminal 210 from shaking or even shifting relative to the waterproof housing 100 due to a large insertion force. This ensures that the conductive terminal 210 can abut against and be electrically connected to the conductive end of the connector, thereby greatly improving the stability of the battery structure 10 used in unmanned express delivery vehicles.

[0041] like Figure 1 As shown, in one embodiment, the gap between the outer periphery of the upper shell 170 and the outer periphery of the lower cover 180 is filled with a second waterproof sealing block (not shown) so that the lower cover 180 can be securely sealed to the upper shell 170, preventing external water or other conductive liquids from entering the sealing and limiting cavity 110.

[0042] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
