Description

Technical Field

[0001] The present application relates to a garden tool. Background Art

[0002] Garden tools, including but not limited to chain saws, trimmers, hedge trimmers, etc., need to be provided with electric energy during use to support the operation of the garden tools. In order to facilitate the garden tools to be carried to any desired place for work, rechargeable battery packs are generally configured on the garden tools. This also means that the battery pack and the garden tools need to be detachable. How to achieve convenient and quick detachable installation of the two has always been a concern of technicians in this field.

[0003] In addition, in order to improve the working endurance of garden tools, it is expected that the battery pack discharge time is as long as possible, which will lead to the increase in the size and weight of the battery pack, which brings difficulties and challenges to the installation of the battery pack on the garden tool. Specifically, the battery pack is large in size and weight, which makes it inconvenient for users to plug and unplug, and at the same time occupies a large space in the shell of the garden tool, hindering the user's grip and affecting the user experience. Utility Model Content

[0004] In view of this, the utility model provides a gardening tool, which can at least partially solve one of the above problems.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] A garden tool, characterized by comprising:

[0007] case;

[0008] A working element, disposed on the housing, and capable of being driven to perform a working task;

[0009] A battery pack, detachably mounted on the housing, for providing the working element with electrical energy required for operation;

[0010] The housing is provided with a battery receiving cavity for receiving the battery pack, and a movable latch provided in the housing; the latch is provided with a locking end at an end close to the battery receiving cavity, and the locking end is used for detachably cooperating with the battery pack;

[0011] The latch moves within the housing to have a locked position and an unlocked position;

[0012] When the lock latch is in the locked position, the locking end extends into the battery receiving cavity and cooperates with the battery pack, so that the battery pack is in a locked state locked in the battery receiving cavity;

[0013] When the latch is in the unlocked position, the locking end is retracted into the housing to be disengaged from the battery pack, and the battery pack is in an unlocked state that can be removed from the battery accommodating cavity.

[0014] Preferably, the housing is formed with a handle for a user to hold; the battery accommodating cavity is located at the proximal end of the handle, and the latch is arranged at the proximal end of the handle.

[0015] Preferably, the handle extends substantially along a direction defined from the battery accommodating cavity to the working element, and a placement groove extending substantially in the same direction as the battery accommodating cavity is formed in the handle, and the latch is limited in the placement groove and can slide therein.

[0016] Preferably, the lock latch is provided with an unlocking operating member, the outer end of which is exposed to the outside of the handle and is used to be operated to drive the lock latch to move to the unlocking position.

[0017] Preferably, the number of the unlocking operating members is two, and the two unlocking operating members are respectively located on both sides of the latch along the movable direction of the latch.

[0018] Preferably, when the battery pack is in a locked state, one end of the battery pack is exposed to the outside of the opening end of the battery accommodating cavity.

[0019] Preferably, the outer wall of the battery pack is provided with a locking block for cooperating with the locking end. When the lock latch is in the locked position, the locking end extends into the battery accommodating cavity and locks with the locking block, so that the battery pack is in a locked state. When the lock latch is in the unlocked position, the locking end is disengaged from the locking block, so that the battery pack is in an unlocked state.

[0020] Preferably, the battery pack is configured to be insertable into the battery receiving cavity through the open end thereof along an assembly direction;

[0021] The locking end has a first locking surface, and the locking block has a second locking surface for cooperating with the first locking surface; the normal direction of the first locking surface is substantially the same as the assembly direction, and the normal direction of the second locking surface is substantially opposite to the assembly direction; when the battery pack is in a locked state, the first locking surface is located upstream of the second locking surface along the assembly direction.

[0022] Preferably, the locking end also has an inclined first guide surface, and the locking block also has an inclined second guide surface; the first guide surface is located upstream of the first locking surface along the assembly direction, and the second guide surface is located downstream of the second locking surface along the assembly direction; when the battery pack is inserted into the battery accommodating cavity along the assembly direction, the first guide surface contacts the second guide surface so that a first force is applied to the latch, and the first force is used to retract the locking end into the shell.

[0023] Preferably, an elastic reset member is provided between the housing and the latch for applying a second force to the latch, wherein the second force is used to maintain the latch in the locked position or to make the latch tend to move toward the locked position.

[0024] Preferably, the end of the latch facing away from the locking end is recessed inward to form a groove; one end of the elastic return member is arranged in the groove, and the other end abuts against the inner wall of the shell.

[0025] By providing a movable latch in the housing of the garden tool, the latch can be moved so that the locking end that cooperates with the battery pack can be moved into the battery receiving cavity or retracted into the housing, thereby quickly achieving locking and disengagement with the battery pack, thereby achieving locking or unlocking of the battery pack in the battery receiving cavity. It can be seen that the present embodiment is a detachable connection and fixing scheme for the battery pack and the housing of the garden tool, and the structure is relatively simple. In practice, the user only needs to perform corresponding operations on the latch to unlock the battery pack, which is relatively convenient to operate.

[0026] In addition, the latch is arranged near the proximal end of the handle and the latch is designed to be relatively small in size or volume, so that the majority of the handle that is held by the user is not affected by the latch. Therefore, when the user holds and operates the handle, the latch will not interfere, so the user has a better feeling of use.

[0027] Furthermore, in certain embodiments, by arranging the battery receiving cavity for installing the battery pack at the proximal end of the handle and arranging the latch near the proximal end of the handle, it means that the latch is relatively close to the battery receiving cavity, or the latch is close to the object it acts on or cooperates with (battery pack). In this way, the volume of the latch and the moving range or distance for locking or unlocking the battery pack will be reduced accordingly, thereby effectively reducing the volume of the entire device and improving space utilization. In addition, the latch is designed to be located on the handle and is close to the battery pack, so that the user can easily operate the latch even when holding the handle, thereby making the unlocking operation of the battery pack relatively simple.

[0035] The terms "near" and "far" used in this embodiment are relative to the user operating the garden tool 100. The term "near" refers to a direction relatively close to the user, and the term "far" refers to a direction relatively far from the user. For example, the battery pack 4 is at the near end, and the working element 2 is at the far end.

[0036] It should be noted that the directional terms such as "near" and "far" are defined for the convenience of description. When the garden tool 100 is used in many other directions and positions, these terms expressing relative positional relationships are not limited and absolute. For example, the above definitions of various directions are only for the convenience of explaining this embodiment, and do not limit the directions of the garden tool 100 of this embodiment in other scenarios including but not limited to product testing, transportation and manufacturing, which may cause it to be reversed or its position changed. In this embodiment, if the above definitions have other clear provisions and limitations, they should follow the above clear provisions and limitations.

[0037] like Figure 1 and Figure 2 As shown, the garden tool 100 of this embodiment includes a housing 1, a working element 2 disposed on the housing 1 and driven to perform a working task, and a detachable battery pack 4 disposed on the housing 1 for providing the working element 2 with electrical energy required for its operation.

[0038] The garden tool 100 of this embodiment can be any type of handheld and needs to be powered by a battery pack for mobile operation, such as a chain saw, a trimmer, a hedge trimmer, etc. The working element 2 is different for different types of garden tools 100. For example, when the garden tool 100 is a chain saw, the working element 2 is a cutting element. When the garden tool 100 is a trimmer, the working element 2 is a trimming element. When the garden tool 100 is a hedge trimmer, the working element 2 is a shearing blade.

[0039] Therefore, the solution of this embodiment can be applied to any of the garden tools 100 listed above, and this embodiment does not limit this. This article mainly describes the chain saw as the main scenario, but based on the above description, it can be seen that the protection scope of the embodiment of the utility model is not limited thereto.

[0040] Any type of garden tool 100 exemplified above may also include other functional components that support the operation of the working element 2, such as a driving part, a control part, etc. It should be noted that these functional components may be selected from any suitable existing structures. In order to clearly and briefly describe the technical solution of the embodiment of the utility model, the above-mentioned parts will not be described in detail here, and the drawings of the specification are also simplified accordingly. However, it should be understood that the scope of the implementation of the utility model is not limited by this.

[0041] like Figure 3 As shown, the housing 1 is provided with a battery receiving chamber 101 for receiving the battery pack 4. The battery receiving chamber 101 is designed with a hollow support structure to reduce the weight of the whole device. The battery receiving chamber 101 forms a retaining portion 102 near the inner wall of the housing 1. The retaining portion 102 is provided with a connecting terminal 103 for electrically connecting to the battery pack 4. The battery receiving chamber 101 is open at the upper end, and the battery pack 4 can be inserted into the battery receiving chamber 101 through the upper end opening along the assembly direction F. The assembly direction F is as follows. Figures 2 to 4 Specifically, the battery pack 4 slides downward along the retaining portion 102 until the lower end abuts against the bottom of the battery accommodating cavity 101 , completing the installation of the battery pack 4 and achieving connection with the connecting terminal 103 at the same time.

[0042] like Figure 4 As shown, a movable latch 5 and a through hole 104 connected to the battery receiving cavity 101 are also provided in the housing 1. Figure 6 and Figure 7 As shown, the latch 5 is close to the end of the battery receiving cavity 101 (such as Figures 3 to 7The latch 5 (shown as the right end) is formed with a locking end 501 for detachable cooperation with the battery pack 4. That is, the latch 5 moves relative to the housing 1 and has a locking position and an unlocking position, and the locking end 501 can enter the battery receiving cavity 101 through the through hole 104 or retract into the housing 1. When the latch 5 is in the locking position, the locking end 501 extends into the battery receiving cavity 101 and cooperates with the battery pack 4, so that the battery pack is locked in the battery receiving cavity 101, and the battery pack 4 is in a locked state. When the latch 5 is in the unlocking position, the locking end 501 retracts into the housing 1 and is disengaged from the battery pack 4, and the battery pack can be removed from the battery receiving cavity 101, and the battery pack 4 is in an unlocking state.

[0043] like Figure 4 As shown, the outer wall of the battery pack 4 (specifically, the outer wall close to or facing the holding portion 102) is provided with a locking block 401 for cooperating with the locking end 501. When the latch 5 is in the locked position, the locking end 501 extends into the battery receiving cavity 101 and locks with the locking block 401, and the battery pack 4 is locked in the battery receiving cavity 101. When the latch 5 is in the unlocked position, the locking end 501 is disengaged from the locking block 401, the battery pack 4 is unlocked, and can be taken out from the open end of the battery receiving cavity 101.

[0044] By providing a movable latch 5 in the housing 1 of the garden tool 100, the latch 5 is moved so that the locking end 501 used to cooperate with the battery pack 4 (locking block 401) is moved into the battery accommodating cavity 101 or retracted into the housing 1, so that the battery pack 4 (locking block 401) can be quickly locked or disengaged, thereby achieving the locking or unlocking of the battery pack 4 in the battery accommodating cavity 101. It can be seen that the present embodiment is a detachable connection and fixing scheme for the battery pack 4 and the housing 1 of the garden tool 100, and the structure is relatively simple. In practice, the user only needs to perform corresponding operations on the latch 5 to unlock the battery pack 4, which is relatively convenient to operate.

[0045] like Figures 1 to 4 As shown, the housing 1 is formed with a handle 105 for the user to hold, the battery receiving chamber 101 is located at the proximal end of the handle 105, and the latch 5 is arranged at the proximal end of the handle 105. In this embodiment, the handle 105 is located at the proximal end of the garden tool 100 as a whole, or closer to the proximal end relative to the working element 2. The battery receiving chamber 101 is also closer to the proximal end relative to the handle 105. The latch 5 is arranged at the proximal end of the handle 105 and the distal end of the battery receiving chamber 101, that is, the latch 5 is arranged on the handle 105 as a whole and is located at the distal end of the battery receiving chamber 101 of the handle 105.

[0046] By arranging the battery receiving chamber 101 for installing the battery pack 4 at the proximal end of the handle 105, and arranging the latch 5 near the proximal end of the handle 105, it means that the latch 5 is relatively close to the battery receiving chamber 101, or the latch 5 is close to its action or cooperation object (battery pack 4). In this way, the volume of the latch 5 and the moving range or distance for locking or unlocking the battery pack 4 will be reduced accordingly, thereby effectively reducing the volume of the whole machine and improving space utilization. In addition, the position design of the latch 5 on the handle 105 and the close distance to the battery pack 4 make it convenient for the user to operate the latch 5 even when holding the handle 105, thereby making the unlocking operation of the battery pack 4 relatively simple.

[0047] In addition, the latch 5 is arranged near the proximal end of the handle 105, and the latch 5 is designed to be relatively small in size or volume as described above, so that the majority of the handle 105 that is held by the user is not affected by the provision of the latch 5. Therefore, when the user holds and operates the handle 105, the latch 5 will not interfere, so that the user has a better feeling of use.

[0048] Further, the handle 105 extends roughly along the direction defined by the battery accommodating cavity 101 to the working element 2, that is, the handle 105 extends along the direction from near to far. A placement groove 106 extending roughly in the same direction is formed in the handle 105, and the latch 5 is limited in the placement groove 106 and can slide in the placement groove 106. In this embodiment, the housing 1 (handle 105) is formed by splicing left and right Havers structures, and accordingly, the placement groove 106 is formed by the Havers structures on both sides of the housing 1 abutting against each other. The placement groove 106 for accommodating or limiting the latch 5 is arranged in the handle 105 in a roughly unidirectional manner, which is equivalent to using the natural or existing structure of the handle 105 to provide a setting and moving space for the latch 5. This not only satisfies the free movement amount required for the latch 5 to lock or unlock the battery pack 4, but also makes full use of the functional characteristics of the known structure to the maximum extent, thereby avoiding structural changes and simplifying the structural complexity to the maximum extent.

[0049] like Figure 4 As shown, an elastic reset member 107 is provided between the housing 1 and the latch 5, and is used to apply an elastic force to the latch 5. The elastic force makes the locking end 501 tend to extend into the battery receiving cavity 101 or keeps the locking end 501 extending into the battery receiving cavity 101, that is, keeps the latch 5 in the locked position or makes the latch 5 tend to move to the locked position. The elastic reset member 107 can be a linear coil spring, and its two ends are biased and arranged on the housing 1 and the latch 5, specifically, one end abuts against the bottom wall of the placement groove 106, and the other end abuts against the inner end of the latch 5 (defined as the end facing away from the locking end 501, or as Figure 6Thus, the elastic reset member 107 always exerts an outward force (defined as Figures 2 to 4 to the right, or to the proximal direction, or to the direction of the battery receiving cavity 101), to ensure that in the absence of external force, the locking end 501 of the latch 5 can always remain extended into the battery receiving cavity 101, that is, the battery pack 4 can always be in the desired locked state, avoiding arbitrary movement of the latch 5 and the resulting unexpected unlocking of the battery pack 4.

[0050] like Figure 6 As shown, the end of the latch 5 facing away from the locking end 501 (the inner end referred to above) is recessed inward to form a groove 502, one end of the elastic reset member 107 is arranged in the groove 502, and the other end is in contact with the inner wall of the housing 1. In this way, the groove 502 can play a role in straightening the compression or extension movement of the elastic reset member 107, ensuring that the elastic reset member 107 can maintain the contact or configuration state with the latch 5 for a long time. At the same time, the above-mentioned straightening effect can also prevent the elastic reset member 107 from scratching the inner wall of the placement groove 106 when it is bent unexpectedly, thereby preventing the latch 5 from being blocked from moving.

[0051] Furthermore, the latch 5 is provided with an outwardly protruding stopper 504, which is located in the seating groove 106 and on the inner side of the penetration hole 104, and is used to limit the outward movement of the latch 5 to prevent the latch 5 from moving outward under the action of the elastic reset member 107 and escaping from the seating groove 106.

[0052] The latch 5 is provided with an unlocking operating member 503, the outer end of which is exposed to the outside of the handle 105, and is used to be operated to drive the latch 5 to move in a direction away from the battery receiving cavity 101, that is, to the unlocking position. Figure 2 As shown, the handle 105 is provided with a substantially long strip-shaped opening 108 for exposing the outer end of the unlocking operating member 503, and the long strip shape provides a moving stroke for the unlocking operating member 503. Therefore, in this embodiment, the locking and maintaining of the battery pack 4 by the latch 5 can be achieved by the elastic return member 107. The unlocking of the battery pack 4 by the latch 5 can be achieved by the unlocking operating member 503.

[0053] Preferably, there are two unlocking operating members 503, which are symmetrically arranged on both sides of the movable direction of the latch 5, specifically on the left and right sides. In this way, the user can operate two unlocking operating members 503 at the same time with one hand, and the experience in force balance and operation convenience is better. Of course, there can also be one unlocking operating member 503, which is arranged on the left / right / upper side of the handle 105, and this embodiment is not limited to this.

[0054] Furthermore, if Figure 2 and Figure 4As shown, when the battery pack 4 is in the locked state, one end of the battery pack 4 (such as Figure 2 and Figure 4 The upper end (shown in the figure) is exposed to the outside of the open end of the battery receiving cavity 101. This structural design can be achieved by configuring the depth of the hollow battery receiving cavity 101. Through this design, after unlocking, the user can operate the exposed end portion of the battery pack 4 to take it out of the battery receiving cavity 101 by pinching, holding, pressing, etc., without providing a mechanism in the battery receiving cavity 101 (specifically, the bottom) for popping up the battery pack 4 after it is unlocked (generally speaking, the function of the pop-up mechanism is to expose the upper end of the battery pack 4 to facilitate the user to take out the battery pack 4), thereby simplifying the structure while facilitating the operation of taking out the battery pack 4.

[0055] like Figures 3 to 7 As shown, the locking end 501 has a first locking surface 5011, and the locking block 401 has a second locking surface 4011 (such as Figure 5 As shown). Both the first locking surface 5011 and the second locking surface 4011 are planes, wherein the normal direction of the first locking surface 5011 is substantially the same as the assembly direction F, or the first locking surface 5011 faces the assembly direction F. The normal direction of the second locking surface 4011 is substantially opposite to the assembly direction F, or the second locking surface 4011 faces away from the assembly direction F. When the battery pack 4 is inserted into the battery accommodating cavity 101 and the locking end 501 is in a state of being locked with the locking block 401, the first locking surface 5011 is located upstream of the second locking surface 4011 along the assembly direction F. In this way, the first locking surface 5011 can serve as a stop for the second locking surface 4011, thereby preventing the battery pack 4 equipped with the locking block 401 from moving in a direction away from the assembly direction F (that is, as shown in FIG. 1 ). Figure 4 The battery pack 4 is moved in the battery receiving cavity 101 (in the upward direction as shown), so that the battery pack 4 is firmly positioned and fixed in the battery receiving cavity 101.

[0056] Furthermore, the locking end 501 further has an inclined first guide surface 5012, and the locking block 401 further has an inclined second guide surface 4012 (such as Figure 5 ). The first guide surface 5012 is located upstream of the first locking surface 5011 along the assembly direction F, and the second guide surface 4012 is located downstream of the second locking surface 4011 along the assembly direction F. Specifically, as Figure 7 As shown, the first locking surface 5011 is provided on (or is) the lower surface of the locking end 501, and the first guide surface 5012 is formed on the lower surface of the locking end 501, or is formed by the upper surface of the locking end 501 being tilted downward. Similarly, the second locking surface 4011 is provided on (or is) the upper surface of the locking block 401, and the second guide surface 4012 is formed on the lower surface of the locking block 401, or is formed by the lower surface of the locking block 401 being tilted upward.

[0057] When the battery pack 4 is inserted into the battery receiving cavity 101 along the assembly direction F, the first guide surface 5012 contacts the second guide surface 4012, so that a force is applied to the latch 5, and the force retracts the locking end 501 into the housing 1. In this way, with the cooperation of the two inclined guide surfaces 4012, 5012, it is helpful to reduce the resistance of the battery pack 4 being inserted downward into the battery receiving cavity 101, making it easier to install the battery pack 4.

[0058] Therefore, the installation and removal process of the battery pack 4 is generally as follows:

[0059] When the battery pack 4 is inserted into the battery accommodating cavity 101 along the assembly direction F (downward), the second guide surface 4012 on the locking block 401 abuts against the first guide surface 5012 on the locking end 501, thereby pushing the latch 5 to move into the housing 1, and the elastic reset member 107 is in a compressed state. After the battery pack 4 is fully installed in the battery accommodating cavity 101, the elastic reset member 107 is released, pushing the latch 5 to move toward the battery accommodating cavity 101, and the second locking surface 4011 of the locking block 401 abuts against the first locking surface 5011 on the locking end 501, and the battery pack 4 cannot be removed from the battery accommodating cavity 101. At this time, the battery pack 4 and the battery accommodating cavity 101 are in a locked state where there is no relative movement between the two.

[0060] When the user slides the unlocking operating member 503 forward, the locking end 501 of the latch 5 retracts into the housing 1, and the first locking surface 5011 on the locking end 501 loses the limiting and stopping effect on the second guide surface 4012 on the locking block 401. At this time, the battery pack 4 can be removed from the battery accommodating cavity 101, and the two are in an unlocked state where relative movement can occur.

[0061] The above are only several embodiments of the present invention. Those skilled in the art can make various changes or modifications to the embodiments of the present invention based on the contents disclosed in the application documents without departing from the spirit and scope of the present invention.
